The force ring (14) and mass element (18) thereby cooperate to exert radially compressive force on the crystal (16), thus effecting friction locks between the radially adjacent pairs of elements which make up the nested combination (14, 16, 18).

Abstract: A method of producing a discarding propelling cage sabot projectile, and to a discarding propelling cage sabot projectile produced according to this method, in which, in a vulcanizing tool including an injection mold, a uniformly thin layer of rubber is applied to the rear gas pressure receiving surface of the sabot so as to secure and seal the individual sabot segments against one another. In such a method, when the liquid sealing material is injected into the injection mold, there exists the danger that, due to the high pressure existing at that time, sealing material may enter, in an uncontrolling manner, into the cylindrical inner annular gap or annulus between the sabot and the projectile body. This may considerably adversely influence the release behavior of the discarding sabot segments and lead to a reduction of hit accuracy.

Abstract: A utility knife employs a slide having a cantilevered lever for capturing a blade therein. A leading blade in a reservoir is capturable by the slide using a tooth resiliently affixed to the slide which is positioned to enter a locking hole in the blade. The tooth may be withdrawn from the hole in the blade whereby the blade may be removed for reversal and reinsertion or for discard. When the captured blade is removed, the slide may be returned to the loading position for capturing the next blade from the reservoir. As long as a captured blade is engaged by the tooth, the slide is prevented from returning to the loading position, and the loading blade in the reservoir is prevented from advancing.

Abstract: An optical system for aiding the driver of a vehicle in judging the proximity of the forward end of the vehicle to an object directly in front of the vehicle, particularly when parking close to a wall or barricade or when pulling up close to another vehicle stopped at an intersection. An illuminated target and a mirror mounted beneath opposite sides of the dashboard are used to reflect an image of the target off the interior surface of the windshield at a location so that the reflected image is in the normal field of view of the driver. A virtual image of the target is perceived by the driver to emanate from a position above the forward end of the vehicle. The driver may gradually advance the vehicle until the virtual image appears to the driver to be juxtaposed with the object at which time there will be a predetermined minimum safe distance between the forward end of the vehicle and the target.

Abstract: A lift-off shoe system uses non-locking sash support shoes (30) movable vertically and spring biased upwardly in a tilt window. Sash pins (25) have heads (26) that interlock with open top slots (31) in sash shoes (30) so that the sash pins are removable from the shoes only by lifting the pins vertically from above the uppermost position of the shoes. This simplifies the shoes, eliminates damage caused by shoe-locking mechanisms, and makes sash removal and replacement simple and convenient.

Abstract: The invention concerns a tensioning device for the cable of a cable window lifter which is mounted in a drive bracket pulled up and down along a guide rail by means of a cable wound around an actuation drum. One cable end is solidly joined to the drive bracket whereas the other cable end is connected by a directional lock to the drive bracket. This directional lock compensates any cable elongation taking place within the cable actuation system by means of spring action. The tensioning device of the invention is characterized by providing further compensating means. This further compensation is needed in the event of excessive stresses exerted on the cable actuation system in the closed window position which results in a spurious cable elongation caused thereby. It also eliminates this compensation when this excess stress is no longer present.

Abstract: A window has an inner sash and outer sash that are removable from the frame. A pivotal step is located along an outer surface of the inner sash. For a double-hung window, there are two pivotal steps, one along each side of the outer surface of the inner sash. For a horizontal slider window, there is one pivotal step along a top of the outer surface of the inner sash. When the inner sash is tilted inward or removed from the frame, the pivotal step can be rotated inward to allow the outer sash to be tilted inward or removed. When the pivotal step is in an operating position in the window, it greatly reduces the air flow from an exterior of the window to an interior of the window around the sashes. With previous windows, there is no step immediately adjacent to an outer surface of the inner sash or, if there is such a step, the presence of the step makes the removal of the sashes cumbersome.

The inner sections of the jamb and head members define channels for slidably receiving window units including a pair of rectangular sash frames each formed from extrusions and including snap-fit extruded cap members. The sash frames also receive removable extruded glazing strips which retain glass window panels within the sash frames.
