Embodiments described herein provide for devices and methods for retaining optical devices. The devices and methods described herein provide for retention of the substrate without contacting sensitive portions of the substrate. The devices and methods utilize retention pads or vacuum pins to contact the exclusion zones i.e., inactive areas of the substrate to retain the substrate and prevent the substrate from moving laterally. Additionally, a holding force retains the substrate in the vertical direction, without contacting the substrate. The methods provide for adjusting the devices to account for multiple geometries of the substrate. The methods further provide for adjusting the devices, such as adjusting a gap between the optical device and a suction pad, to alter the holding force of the devices on the optical devices.

A driver device may comprise a housing and a hole located on the housing. The hole may comprise a sealing lip. The driver device may comprise a bit holder located within the housing, and a bit socket located on the bit holder. The bit socket may be aligned with the hole, such that inserting a bit into the bit socket also inserts the bit into the hole. The driver device may comprise a spring located within the bit socket. The spring may cause an inserted bit to partially exit the hole in the absence of an external force pushing the it against the spring. The driver device may comprise a vacuum component connected to the housing, and a vacuum chamber within the housing.

Provided is an alignment tool for a cutting arrangement including a cutting apparatus with a cutting edge for treatment of a workpiece, especially a rotor blade of a wind turbine, in which the alignment tool includes at least one fixation means for fixing the alignment tool to the workpiece and at least one guiding structure to guide the cutting edge of the cutting tool.

A quick-release clamp for a vehicular mount or rack having a rigid stationary first jaw with a clamping surface, and a rigid second jaw opposite with a clamping surface oriented to face the first jaw clamping surface. The second jaw is movable between an open and a closed position relative to the first jaw, where the closed position is capable of retaining one or more objects to be clamped transversely between said jaws. A lever, attached to a variable tensioning system operates to open and close the jaws when sufficient force is applied to overcome the tension of the tensioning system.

Apparatus for use in handling windscreens for example for installation in a vehicle, includes a windscreen anchor assembly comprising a windscreen anchor device and a support arm extending away from the windscreen anchor device. A mount assembly is provided for supporting the windscreen anchor assembly. The mount assembly includes a mount structure for engaging with the support arm such that the support arm can slide bodily in its longitudinal direction with respect to the mount structure.

A vacuum gripper for gripping an object surface using vacuum suction is configured to be portable or operated by a hoist. Battery conservation measures are included to provide a long term vacuum generation capability, together with manually rechargeable mechanism. A manually-operated vacuum pump is also integrated to the vacuum gripper as a safeguard for the battery-operated vacuum pump failure. The vacuum gripper includes an elastic deformable vacuum seal for gripping objects with irregular surfaces, together with press rods or pin array configured to assist the vacuum seal in filling any gaps between the vacuum seal and the object surface.

The invention relates to a leak detection device comprising: a portable leak detection bell-like member comprising a sealing joint and configured to define a detection chamber between the main body and the test zone, the detection bell-like member further comprising a carrying handle which is provided with a control member which can be manually activated to produce a control signal, a gas suction circuit which is intended to connect the detection chamber to a vacuum pump, the gas suction circuit being provided with a controlled valve which can be switched into an open state to connect the detection chamber to the vacuum pump and a closed state to isolate the detection chamber from the vacuum pump, and a control unit which is configured to switch the controlled valve in response to the control signal.

A suction device that holds a member by suction in a stable manner is provided. The suction device includes a columnar main body, a flat end face formed on the main body, a concave part formed in the end face, a fluid flow-forming supply paths for forming a fluid swirl flow in the concave part by discharging fluid into the concave part, the fluid swirl flow generating negative pressure that applies suction to a member, and a linear guide groove formed on the end surface along a direction in which the fluid discharged into the concave part flows out of the concave part.

A vacuum device for a material handling system includes a vacuum device body and a sealing element. The vacuum device body has a vacuum passageway in which H vacuum is generated in response to activation of a pressurized air supply that forces pressurized air through a venturi device. The sealing element moves to a sealing position to substantially seal the vacuum passageway when the air supply is activated, and is urged toward the sealing position via pressurized air that is diverted from an inlet of the vacuum device to the sealing element. The sealing element moves to substantially vent the vacuum passageway when the air supply is deactivated. The vacuum passageway may be in fluid communication with a vacuum cup, which seals against the object when the sealing element is at the sealing position and the vacuum generating device generates at least a partial vacuum in the vacuum passageway.

An end cap holder includes a main body and a pump which generates a vacuum pressure. The main body includes a bore hole extending therethrough along a central axis, and a contact surface which surrounds an end of the bore hole. Activation of the pump may generate a vacuum pressure within the bore hole.
