An applicator machine and a process for heating and coating a section of pipeline. The applicator machine includes a frame configured to rotate about a section of pipeline to be heated and coated, rotating means operable to rotate the frame, and coating material applicators induction coils and radiant heaters mounted on the frame and rotatable therewith. The induction coil is configured to heat a section of pipeline adjacent to the induction coil to a coating material application temperature. The radiant heaters are configured to heat factory-applied coatings. Each coating material applicator sprays coating material through an aperture in a respective induction coil. The applicator includes an enclosure configured to surround a section of pipeline and provision for evacuating and collecting waste coating material. The coating material applicator may be configured to spray powder coating material, such as fusion bonded epoxy powder material and/or chemically modified polypropylene powder material.

Cold spray devices and systems are disclosed. They include a flowpath having an inlet adapted for receiving communication with two or more inputs and an outlet adapted to discharge the two or more inputs. A discharge nozzle may be included in the flowpath of the outlet and a confluence may be included in the flowpath at the inlet for combining the two or more inputs. A nozzle body houses the discharge nozzle separate and downstream from the confluence of the two inputs.

Dispensing device for granular or powdered materials, comprising: a dispensing channel (2a), provided with a longitudinal axis (X), an inlet opening (21) and an outlet opening (22); suction means, arranged to retain, on command, at least a portion of granular or powdered material in contact with an inner surface of the dispensing channel (2a), so as to form an accumulation which obstructs the dispensing channel (2a) and prevents the flow of material.

A device for delivering a predetermined amount of a substance within at least one body cavity of a subject, where the predetermined amount is at an effective amount for treatment of obesity or binge eating disorder. The device includes (a) A volume to contain the predetermined amount of the substance. (b) A delivery end placeable in proximity to the body cavity. The delivery end is in fluid communication with the volume and comprises at least one orifice. (c) A valve mechanically connected to the volume, with at least two configurations: (i) an active configuration configured to deliver the predetermined amount of the substance; and, (ii) an inactive configuration, in which the valve prevents delivery of the predetermined amount of the substance. (d) A fluid tight chamber configured to contain a predetermined volume of pressurized gas at a predetermined pressure.

Systems, apparatus, and method for manufacturing are disclosed. In an aspect, the apparatus may be a cold-spray nozzle. The cold-spray nozzle may include a variable diameter convergent part. The cold-spray nozzle may also include a variable diameter divergent part. The variable diameter divergent part may form a diffuser. Additionally, The cold-spray nozzle may include a ring portion. The ring portion may couple the variable diameter convergent part and the variable diameter divergent part. Additionally, the ring portion may control the opening to the diffuser.

A blasting device has a spray unit for spraying blasting agent onto the surface to be treated. The spray unit has an insert 23′ in which a nozzle 13′ is rotatable. This nozzle 13′ is provided with a number of spray channels 19′ which are at an angle 21′ relative to the supply direction 17 of the blasting agent. The blasting agent is pressed through the spray channels 19′ under pressure and exerts a force on the wall of the spray channels 19′ causing the nozzle 13′ to rotate. The jets emerging from the rotating nozzle 13′ will make a rotating movement. The joint area of the cross-sections of the spray channels 19′ is larger than one third of the cross-sectional area of the circular-cylindrical part of the nozzle. The angle 21′ at which the spray channels are located with respect to the supply direction 17 of the blasting agent is greater than zero and less than 10 degrees.

The present invention relates to an aerosol device comprising: —a container containing a cosmetic composition which comprises one or more powders in a content of less than 7% by weight relative to the total weight of the composition, and—a dispensing head comprising a body and an end part comprising at least two outlet orifices configured to allow spraying of the composition about a longitudinal axis of the end part in at least two different directions, the dispensing head comprising at least first and second chambers, through which the composition stream successively passes before it exits via the outlet orifices.

Various embodiments disclosed relate to a method of cold-spray deposition involving cooling the cold-spray nozzle by at least one of expanding and vaporizing a compressed cooling fluid in proximity to the cold-spray nozzle. The present disclosure also includes a cold-spray deposition spray head, a cooling jacket for a cold-spray deposition nozzle and a cold-spray deposition system comprising the same.

Apparatus for forming a 3D object from powder, comprising: a) delivery means adapted to emit a flow of powder at sufficiently high velocity to enable it to form the 3D object; b) positioning means adapted adjust the position of the delivery means; and c) control means adapted to control: i) movement of the positioning means; and ii) the velocity of the flow of powder.

A new spray process allows for deposition below a critical velocity limit of cold spray, while providing adhesion. Post deposition heat treatment has shown excellent coating strength. A wide variety of materials can be deposited. The spray process is based on ShockWave Induced Spraying (SWIS) but with much slower spray jet projection velocities. High porosity, pore size control, and porosity control are demonstrated to be controllable. Preheating of feedstock and uniform temperature of the SWIS delivery allow for the deposition below critical velocity.
