SECURING A SECOND OBJECT TO A FIRST OBJECT
A method of anchoring a connector in a first object, wherein the first object is a lightweight building element having a first outer building layer and an interlining layer, and wherein the connector includes thermoplastic material in a solid state. The method includes: bringing a coupling surface portion of the connector into contact with an attachment location of the first outer building layer; displacing a portion of the first outer building layer at the attachment location with respect to the interlining layer by applying a first pressing force to the first outer building layer and thereby piercing the first outer building layer; applying a second pressing force to the connector and transferring energy to the connector until a flow portion of the thermoplastic material has liquefied and flown to interpenetrate structures of the interlining layer; and stopping the energy transfer and allowing the flow portion to re-solidify.
METHOD FOR JOINING A DEVICE TO AN OBJECT WITH THE AID OF ULTRASONIC VIBRATION ENERGY AND DEVICE AND INSTALLATION SUITABLE FOR THE METHOD
A method for joining a device to an object with the aid of a combination of ultrasonic vibration energy and induction heating, wherein the device includes a portion of a thermoplastic polymer and a susceptor additive wherein this portion is at least partly liquefied or plasticized through the ultrasonic vibration energy in combination with the induction heating and wherein the joining includes establishing a connection between the device and the object which connection is at least one of a positive fit connection, a weld, a press fit connection, and an adhesive connection. The induction heating is applied for rendering the device portion suitable for absorption of ultrasonic vibration energy than other device portions by raising its temperature above the glass transition temperature of the polymer. The ultrasonic vibration energy is used for liquefying or at least plasticizing the thermoplastic polymer of the named device portion.
METHODS FOR INCREASING A RETENTION FORCE BETWEEN A POLYMERIC SCAFFOLD AND A DELIVERY BALLOON
A medical device-includes a scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes inflating the delivery balloon during a diameter reduction to improve scaffold retention and maintaining an inflated balloon during the diameter reduction and prior and subsequent dwell periods.
Systems and methods for improved ultrasonic welding using energy-director-locating algorithm
A process, for locating a welding energy director, for effective welding together of multiple workpieces at an area of the director. The director includes positioning a workpiece arrangement in preparation to make approaches, for locating the director, wherein the workpiece arrangement includes a proximate workpiece of the multiple workpieces, a distal workpiece, and the welding director positioned therebetween. The process also includes performing a sub-routine comprising moving a locating implement toward the proximate workpiece. The routine also includes determining whether a push-back force, being received at the locating implement from the workpiece, indicates that the locating implement has been lowered to a local terminal point. The routine includes relocating, in response to a negative result, the implement for repeating until a positive result, and determining, in response to the positive results in the location determination, that the director is located directly beneath an area corresponding to the positive result.
Methods for increasing a retention force between a polymeric scaffold and a delivery balloon
A medical device-includes a scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes inflating the delivery balloon during a diameter reduction to improve scaffold retention and maintaining an inflated balloon during the diameter reduction and prior and subsequent dwell periods.
GEAR HOUSING ESPECIALLY FOR AN EPICYCLIC GEAR SET AND METHOD OF MAKING SAME
A gear housing for an epicyclic gear set, the gear housing including a hollow wheel having internal teething and a first front end with a first front-side joining surface; a housing cover having a second front end with a second front-side joining surface for longitudinally axially covering the hollow wheel; and a bonded connection for connecting the first front end to the second front end through the mating of the first and second front-side joining surfaces, at which the hollow wheel and the housing cover are connected to each other by a bonded connection, in particular, by heated tool welding, infrared welding, ultrasonic welding, or rotary friction welding.
Device and method for detecting defects during sealing of a package comprising a foil
A device for detecting defects during sealing of a package including a foil, and a method for detecting defects during sealing of a package including a foil which makes use of such a device. The device may include a distance sensor for determining the distance between at least two clamping elements, and a control unit coupled to the distance sensor for comparing the measured distances to predefined references. Such a device may be operated by, for example, positioning a foil and another part of a package to be connected to the foil between the clamping elements, moving the clamping elements toward one another until a connection between the foil and the other part of the package is formed, determining the distance between the clamping elements over a period, moving the clamping elements apart, and removing the package.
ANCHORING IN A LIGHTWEIGHT BUILDING ELEMENT
A method of anchoring a connector in a first object is provided, the connector having a thermoplastic material in a solid state. The method includes providing the first object and the connector, bringing the connector into contact with the first object from a distal side thereof, causing mechanical vibration energy to impinge on the first object from a proximal end face thereof, the proximal end face being opposite the distal side, while the object and the connector are pressed against each other, until a proximally facing end of connector is at least partially flowable forming a flow portion of the thermoplastic material, and causing the flow portion to flow into structures of the first object, and letting the flow portion re-solidify to cause a positive-fit connection between the first object and the connector.
ANCHORING IN A LIGHTWEIGHT BUILDING ELEMENT
A method of anchoring a connector in a heterogeneous first object that includes a first building layer and, distally of the first building layer, an interlining layer. The method includes providing the first object and the connector, which includes thermoplastic material in a solid state; contacting the connector with the first building layer; applying a first mechanical pressing force to the connector until the first building layer is pierced by the connector and a distal portion of the connector reaches into the interlining layer; applying a second mechanical pressing force and mechanical vibration to the connector until a flow portion of the thermoplastic material is flowable and penetrates structures of the first object, and a distally facing abutment face of the head portion abuts against the metal profile in a region next to the opening; and letting the thermoplastic material resolidify to yield a positive-fit connection.
Electrical heating-joining device and method
An electrical heating bonding device 1 bonds a member M1 to be bonded, which is made of a metal, and a member M2 to be bonded, which is made of a resin. The electrical heating bonding device 1 includes: an upper electrode 11 and a lower electrode 12 which sandwich the member M1 to be bonded, and are electrically conductive with the member M1 to be bonded; a pressurizing unit 20 which applies pressure to a bonding surface between the member M1 to be bonded and the member M2 to be bonded; a temperature sensor 30 which detects a temperature of the member M1 to be bonded; and a control unit 40 which controls the pressurizing unit 20 to apply the pressure to the bonding surface, after the temperature detected by the temperature sensor 30 reaches a predetermined set temperature Ts.
