US Patent:

52696731, Dec 14, 1993

Filed:

Jul 23, 1992

Appl. No.:

7/918246

Inventors:

Joseph Kempf - Roselle IL
John Diamond - McHenry IL

International Classification:

B29C 4584

US Classification:

425151

Abstract:

An injection molding machine is illustrated with tie bars extending from a stationary die plate. A movable die plate is slidably movable along the tie bars. Corrugated elastic sleeves cover the tie bars and are seated at opposite ends on the die plates to keep molded parts from contacting the tie bars when the mold is open and thereby protect the molded parts from contamination by lubricant on the tie bars. In the embodiment shown, the corrugated sleeve is made of plastic material and is split longitudinally to facilitate assembly. The split sleeve construction enables the sleeves to be assembled sidewise onto the tie bars, and held snugly onto the bars by wires or cable ties.

Vapor Corporation - Chicago IL

International Classification:

H01H 316

US Classification:

200 6143

Abstract:

A sensitive edge 10 for door systems, lifts, doors, or other moving portions of transit vehicles that come into contact with articles or passengers includes a body defining a resilient deformable leading edge portion 30 and a base portion 32 within which is defined an internal chamber. A coupling portion is defined on and extending from the base for coupling the sensitive edge to the door or similar device 36. The chamber 34 is hollow and at atmospheric pressure and in the preferred embodiment, is filled with air. Within the chamber is mounted a Wiegand wire and pick-up coil 38 that is electrically coupled to a switch for recycling the door or similar device upon engagement of the sensitive edge with an object such as a passenger. Also mounted within the chamber and spaced from the Wiegand wire or pick-up coil and wire is a magnet or similar magnetic field creating device 40 such that upon deformation of the sensitive edge, the magnet and Wiegand wire are brought sufficiently close together to cause a switching function to open the door or similar device.

US Classification:

Abstract:

A contactless pressure switch 10 sensitive to fluid pressure rates of change includes a housing 36 and a diaphragm 42 secured in the housing defining first and second chambers. Ports 48, 50 are included in the first and second chambers to vent the chambers. A magnet 52 is secured to the diaphragm and a switching module 54 is secured to the housing within one of the first or second chambers at a position spaced from the diaphragm. A biasing magnet 53 is mounted with the module to provide symmetrical switching by the module. The other of the first or second chambers is coupled to a sensing tube 28 such that upon a pulse or rate change of pressure being introduced in the other of first and second chambers, the diaphragm is deflected. This moves the magnet 52 toward the module actuating it to switch the module and actuate a desired circuit. In an alternative embodiment, the position of the module may be varied relative to the diaphragm to vary the sensitivity of the switch.
