Abstract: In a safety-belt system comprising a winding and locking mechanism, a clamping device is provided which carries out a clamping of the safety-belt outside the reel winding, wherein this clamping effect is caused by a lifting motion of the winding and locking mechanism or of a part thereof and is fastened by suitable means so that the load-bearing clamping organ comes to engage with its entire clamping surface on the belt and the approach of the clamping surface to the belt is synchronized. According to the invention clamping readiness of the clamping organ is begun on every vehicle deceleration of more than 0.45 g and on every belt withdrawal acceleration of more than 1.5 g. The belt winder contains, apart from the driving spring and the winding shaft, only the sensor and control mechanism, and does not require any separate locking elements in order to cause preblocking.

Abstract: An edge guard for the trailing edge of a swinging closure comprises a metal strip formed into a general U-shape so as to have inner and outer legs of single thickness extending from a semi-circular base. Non-metallic insulating material is applied to the metal strip so as to be disposed in covering relation to at least certain portions of the strip including a covering relation which prevents the metal of the channel from contacting the trailing edge. Each leg comprises a ridge formed in one or both of the non-metallic material and the metal channel with the ridge projecting laterally of the leg. Various embodiments are disclosed.

Abstract: A removable temporary flood protection device which, when installed in a building doorway, provides a substantially water-tight barrier to entry of flood water through the doorway opening. The flood protection device includes an inner water resistant rigid core and an outer inflatable flexible seal tube. The inner core has a bottom and spaced apart sides which respectively extend generally parallel to the doorsill and door jambs of the doorway and are spaced upwardly and inwardly thereof so that the inner core extends across a lower portion of the doorway opening and thereby providing partial closure thereof except for a narrow space defined between the bottom and sides of the inner core and the doorsill and door jambs of the doorway. The inflatable seal tube is attached to a top of the inner core and extends down along the spaced sides and across the bottom thereof so that the seal tube is located in the narrow space defined between the inner core and the doorway.

Abstract: Electrically-operated hydraulic and mechanical apparatus is disclosed for opening and closing a large door, for example, on a cargo airplane. Door latching or locking apparatus is also disclosed, which serves to prevent the door from being inadvertently opened at any time. The hydraulic and mechanical apparatus are sequentially activated so that, for example, before the door latching operation can begin, full closing of the door is required. Conversely, before opening of the door can occur, full unlatching of the latching mechanism must first occur.

Abstract: An abutment member is mounted on a pair of shafts on which upper and lower rollers are rotatably carried. The abutment member is abuttingly engageable with a wall of a guide rail when both or one of the rollers is caused to move a predetermined amount toward the wall of the guide rail.

Abstract: A security door comprises first and second vertical door jambs spaced from one another to define a doorway therebetween, and a door for closing the doorway. The second door jamb has a generally channel-shaped recess therein extending generally vertically from adjacent the bottom of the jamb to adjacent the top of the jamb. The security door includes a hinge on the first door jamb for supporting the door adjacent one vertical edge of the door, constituting its inner edge. The hinge enables the door to swing on a generally vertical axis between an open position wherein the door is swung out of the doorway and a closed position wherein the door closes the doorway and the opposite vertical edge of the door, constituting its outer edge, is spaced inwardly from the recess in the second door jamb.

Abstract: A console mounted transmission selector assembly has a latching mechanism which is operable to prevent the operator key from being placed in the LOCK position prior to the transmission being shifted to the desired PARK position. The latching mechanism also prevents the transmission selector lever from being shifted out of the PARK position prior to the operator key being manipulated out of the LOCK position. The selector assembly housing has the operator key disposed therein. The key mechanism and the latching mechanism are interconnected by a linkage mechanism which is also disposed within the selector assembly housing.

Abstract: A protective bar for restricting passage through a window type opening in a building structure includes a tubular member adapted to be seated in a recess provided in one side of the window frame with a spring biased slidable bar protruding from the opposite end of the tubular member and adapted to be seated in a recess provided in the opposite window frame member. A malleable material is utilized to form a seat for the spring which biases the rod axially of the tubular member and the malleable material is positively positioned in place by applying axial compression to the material so that it radially expands into a tight frictional relationship with the internal surface of the tubular member. A pull cable release system is also provided which allows the bar to be quickly and easily removed from a location in the interior of the building structure.

Abstract: A spur gear system wherein each gear comprises two gear sections; gear te in the respective sections are staggered a one half tooth pitch distance. The effect is to achieve a relatively high contact ratio with relatively small diameter gears. Teeth on mating gears are of positive (convex) curvature and negative (concave) curvature to provide an enlarged contact area.

Abstract: A window sash in mounted in a window frame by hardware which permits the sash to swing open (1) in an egress mode about an upright axis located closely adjacent one upright side of the frame (2) in a wash mode about an upright axis located near the lateral center of the frame or (3) in an awning mode about a horizontal axis located adjacent the upper side of the frame. All that need be done to change the mode of opening is to switch the position of a single selector lever.

Abstract: An edge guard for the trailing edge of a swinging closure comprises a metal strip formed into a general U-shape so as to have inner and outer legs of single thickness extending from a semi-circular base. Non-metallic insulating material is applied to the metal strip so as to be disposed in covering relation to at least certain portions of the strip including a covering relation which prevents the metal of the channel from contacting the trailing edge. Some non-metallic material is applied to the metal strip at locations where the legs apply self-retention force to the trailing edge and has a higher durometer than at other locations where non-metallic material is applied to the metal channel. In the preferred embodiment the higher durometer material also covers the distal end edge surfaces of the legs.

Abstract: A window or door construction for a building is shown wherein the frame carrying the glass pane or the window or door wing is not fixedly connected to the building but is "floatingly" disposed in a case. Therefore, if adequate spaces are taken into account, the frame can freely move in the case and expand and contract under thermal influences independently of the building. The invention makes it possible to realize window or door constructions of a plastic profile material which, if necessary, also withstand arctic temperatures without their weld joints cracking.
