Title: Headrest for motor vehicle seats
Inventor: BUTZ EUGEN OTTO
IPC: B60N2/48
Filed: 1983-04-21
Abstract: In a headrest for motor vehicle seats, the head upholstery carrier is held so as to be displaceable in relation to at least one head upholstery bearing rod (16). The lower plug-in region of said rod, said region being located in a backrest of a seat, is held in a locking sheath (12) which bears a holding spring (21) in its region facing the head upholstery carrier. The holding spring (21) engages in a locking notch (18) of the head upholstery bearing rod (16) and can be moved out of the locking notch (18) counter to its spring restoring force by pressure-actuation. The holding spring (21) forms a strut which can be actuated by pressure at the end approximately in its longitudinal axis (y). The strut is pre-bent in its locking position inside the locking sheath (12) and faces the head upholstery bearing rod (16) with its hollow side (25). The headrest according to the invention permits a very simple design and at the same time a simple unlocking of the head upholstery bearing rod (16) from the locking sheath (12). <IMAGE>
Patent DE-3316659-A1 (DE)
Title: Ball valve
Inventor: KAWANAMI ISAEO
IPC: F16K27/06
Filed: 1983-05-06
Abstract: A ball valve is described, the insert of which is cemented in a valve body of the valve housing, thereby creating the valve chamber for the rotatable arrangement of the balls. On the surfaces of the valve body and of the insert which are in each case opposite the balls there are provided annular grooves having rectangular cross-sections. Provided in these annular grooves are valve seating rings made of polytetrafluoroethylene, which are backed by flexible rubber rings. In this way, the ball and the insert cannot escape from the valve housing when they are subjected to the pressure of the flow medium, and the sealing effect of the ball valve can be maintained for a long time. In addition, the contact surfaces of the valve housing and of the tubular extensions are designed in the form of complementary spherical surfaces, which can slide one on the other. In this way the effect can be achieved that the ball valve cannot be influenced by overloading forces, even if the pipelines deviate from the axis of the throughflow opening on account of external forces.

Title: Method for the introduction of charge air into the cylinder of a combustion engine and engine for implementing the method
Inventor: SCHATZ OSKAR DR ING
IPC: F02B41/06
Filed: 1983-05-18
Abstract: A method for the introduction of charge air into the cylinder of a combustion engine in which the piston of the engine draws in part of the charge air and additional air is introduced into the cylinder until the required charging pressure is achieved, that is either from the start of intake to the end of intake with gradual increase of the charging pressure to the required value, or only during the piston movement in the area of the bottom dead centre. In order to implement the method, the engine is provided with a displacement supercharger, which has at least one supercharger chamber, the swept volume of which is just large enough for it to meet the maximum air demand of a single engine cylinder for a single working cycle, supercharger and engine piston movement being synchronised in such a way that the supercharger then compresses the air and expels it into the engine cylinder when the engine piston is performing the induction stroke.

Patent DE-3320958-A1 (DE)
Title: Auxiliary and signalling switch
Inventor: HEINDORF HELMUT ING GRAD
IPC: H01H71/46
Filed: 1983-06-10
Abstract: The switch has a contact arrangement (6, 8, 9, 10) which is driven by a mechanism (3, 4, 13) and can assume different switch positions depending on the position of a lever (2) which can pivot about a fixed rotation point (2a). For this purpose, the lever (2) is provided with a cam track (2b) which drives a contact arm (8), which can pivot, via a slide (11). The contact point (8d) of said contact arm (8) is located together with a contact lever (6) having contact points (6c, 6d) in the region between stationary contact points (9, 10). For its part, the contact lever (6) is likewise operated by the lever (2) via the mechanism, which forms a latching point (3a). The closing of the respective contact points (6c/9 and 6d/8d or 6d/8d/10 respectively) is controlled by the mechanism which pivots the contact lever (6) (which is shown in the switched-on position) in the direction of the stationary contact point (10), under the influence of a force store (7) if a line-protection circuit breaker which is coupled thereto trips automatically. In the event of a manual disconnection, the slide (11) which slides on the cam track (2b) engages with its hook (11b) behind the contact arm (8), because of the leading lever movement, so that said contact arm is blocked in its pivoting movement and hence only the contact lever (6) and contact arm (8) touch one another. <IMAGE>

Title: Tennis ball serving system with ball spin
Inventor: DLUGI EBERHARD
IPC: A63B69/40
Filed: 1984-09-05
Abstract: Tennis ball serving systems are designed as ball serving systems in which two counter-rotating discs are adjusted so that the tennis ball, on covering the set distance, is given the necessary serving speed. Any desired direction of service can be obtained by pivoting or sliding the serving discs. The ball serving system invented by me and presented in the claims permits the simulation of all ball serving situations which are possible in tennis. This is because, by pivoting the serving discs from vertical to horizontal 0-90 DEG  to right and left in accordance with the drawing in Figure 2, and the differing speed of rotation of the discs, the tennis ball is given axes of rotation which correspond to all ball trajectory possibilities. My ball serving system now makes it possible to serve all three types of service for right- and left-handers in a correct simulation of play. <IMAGE>
