Title: Reinforced mounting for car seat - has triple ratchet teeth with outer two gripping shear support frame
Inventor: BECKER BURCKHARD
IPC: B60N2/08
Filed: 1980-11-10
Abstract: The sliding seat position is secured by the triple ratchet (20) with the teeth engaging a regularly slotted ratchet rail (25) and with the middle tooth (23) narrower than the slots. A parallel shear support rail (24) has wider slots spaced so that the outer flanges of the outer two teeth (21,22) grip the sides of the slots. The seat setting is secured without danger of vibration. Any excessive impact force on the mounting causes the respective tooth to deform and allows the middle tooth and the other end tooth to grip the shear support rail. The seat mounting provides strong support for seats with safety belts attached.

Title: Method for producing still or moving motion pictures in front of the windows of underground and railway trains moving through tunnels
Inventor: HOCHBERG PETER
IPC: G09F19/22
Filed: 1981-02-18
Abstract: The aim of the present invention, which is designated as "Method for producing still or moving motion pictures in front of the windows of underground and railway trains moving through tunnels", is to employ new methods for the purpose of utilising in front of the windows of moving underground and railway trains surfaces of tunnel walls which to date could not be used or be used only with difficulty by means of conventional methods of informing and advertising (posters, luminous inscriptions). In this case, the cinematographic motion picture effect is utilised to mount individual images of an image sequence of the same or different states of motion in the longitudinal direction of the tunnel wall at the level of the train windows and to render them visible by means of a high-frequency flashlamp in front of the windows of the passing train, when a window is respectively located precisely in front of the individual image. In this case, for the viewer inside the train the different instances of motion imaged on the individual images of the image sequence are combined to form a continuous cycle of motion (motion picture). Likewise, a still motion picture without movement can be generated in front of the viewer's window by rendering visible individual images having in each case the same motifs or sections of motion.

Title: Standing umbrella, in particular garden umbrella
Inventor: MAY ANTON
IPC: A45B23/00
Filed: 1981-04-07
Abstract: A table (25) with a telescopic shaft (18) mounted below it for a crank handle (23) is mounted on a mast (1) held firmly on the ground. By means of this crank, a sliding ring (11) guided on the mast (1) can be adjusted in its height position from the extension position via angular gears (16, 17), a threaded spindle (13) and a nut (12). In the open position, this sliding ring holds the covering rods (7) with the umbrella skin (34) in a horizontal plane via spreading struts (9). When the sliding ring (11) is lowered into the lower end position (11'), the covering rods (7) are pivoted against the edge of the table-top (25) in such a way that the umbrella, as illustrated by dot-dashed lines, forms a truncated cone-shaped enclosure for the mast with the table and the equipment to be set up there, for example chairs (38). It is ensured by the slot bearings (6, 8) that although the umbrella skin (34) is stretched in the open position, the covering rods (7) are moved slightly inwards when it is pivoted down and the tension on the umbrella skin is thus relieved. The crank (22) with the telescopic shaft (18) is located in a sector between two covering rods (7), that is to say is accessible at any time when the umbrella is closed and can be pulled outwards from a retracted position. <IMAGE>

Filed: 1981-10-24
Abstract: The invention describes a process for producing an earth connection (4) between the ends of an electrically conductive element tube (2), which surrounds an insulated heating element (1) with power connection (3). Both the earth connection (4) and the power connection (3) are protected by a plastic plug. The earth connection (4) is equipped with a clip (5), which is attached at a point suitable for it around the ends of the element tube (2), after which the clip (5) and the ends of the element tube are inserted into a two-part injection mould. The tube ends are pressed against the clip (5) by the closure pressure of the mould, as a result of which an adequate earth connection between the ends of the tube (2) is achieved. After this, for moulding the plug, plastic is injected into the mould in a known way. Use is advantageously made of an injection mould which has openings for the tube ends and bends the jaws of the clip (5) around to such an extent that their lateral spacing is slightly less than the corresponding spacing of the openings in the mould. As a result, the clip jaws are put under pressure when the mould is closed. <IMAGE>
