Abstract: A medical apparatus for orienting and guiding a medical implement includes a mechanical mechanism that includes a first mechanism portion and a second mechanism portion. The first mechanism portion includes a contact element for disposition on a selected emplacement on a portion of a body, and the second mechanism portion includes an operation module for guidance and support of the medical implement. The mechanical mechanism permits displacement of the contact element and the operation module relative to each other in bidirectional motion of translation along a segment of a straight line, and maintains the medical implement in permanent aim at the selected emplacement. The operation module also supports an implement guide for support an implement drive which includes a motorized drive for operating medical implements coupled thereto.

Abstract: An internal surface chucking mechanism (ISM) for gripping and for releasing an internal surface of a workpiece (W) in process on a processing machine is configured for reversible exchange with an external surface chucking mechanism (EXS) dedicated to grip an external surface of the workpiece. The ISM fits machinery where the workpiece is rotating and is non-rotating, in a first mode with the EXS, and in a second mode with the ISM, and vice-versa. A fluid conduit inside the ISM provides fluid, such as oil, for exhaust adjacent and opposite the workpiece. An appropriately oriented exit outlet (353) directs a stream of fluid to impinge on the workpiece, to eject it from the ISM when released from grip. The fluid cools and lubricates both the ISM and the workpiece.

Abstract: A contactless window tape alarm interlock device is provided that eliminates the need to manually connect or separate an alarm system and tape strips mounted on panes of glass contained in operable window frames. This prevents breakage of the connections when the window frame positions are shifted for servicing or cleaning. An assembly containing an oscillator, detector and magnetic coupling coils is mounted to each fixed window casement. An electrical tape strip is bonded to each window pane and is connected with a pair of coils contained in an assembly mounted to each moveable window frame. The coil assemblies are located in magnetic proximity to one another. The signal from the oscillator is coupled to the detector via the coils and window tape. Any change in the coupling between coils or a break in any of the strips causes a detector to set off the alarm.

Abstract: A method and apparatus for feeding sheets, particularly fabrics, from a stack comprises an arrangement for: engaging the opposite edges of the upper sheet of the stack by a pair of restrainer members, bringing a pick-up head into engagement with the upper sheet of the stack while producing air streams from the pick-up head directed outwardly across the opposite edges of the upper sheet of the stack, lowering the pick-up head to depress the stack below the restrainer members whereby the air streams cause the opposite edges of the upper sheet of the stack to curl upwardly to clear the restrainer members, lifting the upper sheet from the stack, and permitting the stack to rise so as to bring the next sheet into engagement with the restrainer members.
