Patent CH-690047-A5 (CH)
Inventor: GENTA GERALD
IPC: G04B19/02
Filed: 1996-02-01
Abstract: The control mechanism for the hours and minutes display on a wrist watch includes a balance wheel (15) acting under the effect of a spring, via an ratchet wheel (18) on a cam (12) situated at the centre of the movement. This in turn is linked to the hour hand. The balance wheel (15) is lifted up progressively under the effect of the cam (12), to fall back suddenly once per hour. When the wheel makes these sudden drops, a toothed sector (23) engages a central pinion via a drive chain (24,25,26), the central pinion carrying the minute hand. Thus once per hour the minute hand is returned to its original position. The balance wheel is also linked to a pawl (30) co-operating with a star wheel with twelve branches carrying a disc indicating the hours.
Patent CH-671615-A5 (CH)
Inventor: RUETSCHE WENDOLIN
IPC: F16B7/20
Filed: 1988-01-28
Abstract: A first joint part (6) consists of a bush (10), a joint bolt (11) and a ring (12) and is inserted into the end of the one pipe (2). Two latching tabs (16) of the bush (10) engage thereby in rectangular perforations (5) of the pipe (2). The joint bolt (11) can rotate in the bush (10) and is located with a head (26) thereon. It is connected to the ring (12) in a rotationally fixed manner. This ring has supporting shoulders (32) for supporting the end faces (4) of the pipes (2, 3). On its circumference, it has two key surfaces (34). A second joint part (7) is of cup shape and likewise is latched with latching tabs (42) into perforations (5) of the other pipe (3). The base (43) has an elongated hole (46) through which a lock (45) of the joint bolt (11) can be inserted. After rotation of the bolt (11) through 90 DEG , a spherical supporting surface (47) of the lock (45) rests on the cylindrical supporting surface (44) of the second joint part (7) and tensions the joint. As a result of this design, the joint can be installed quickly and does not project beyond the circumference of the pipes. The joint is particularly suitable for connecting elements of a load-bearing member of a room divider which are arranged one above the other.

Patent CH-684241-A5 (CH)
Title: Method of producing vascular prostheses
Inventor: BITTMANN PEDRO
IPC: A61F2/06
Filed: 1993-12-22
Abstract: It is found that textile vascular prostheses which have been covered with cells, especially endothelial cells, by filtration of a cell suspension through the prosthetic wall, provide better sealing than prostheses of this kind which have not been covered and consequently cause less after-bleeding. However, it is also found that the sealing provided by the covered prostheses is subject to random variation such that the risk of excessive or excessively long after-bleeding is nevertheless unacceptable. According to the invention, the covered prostheses are after-treated in an after-treatment, which directly follows covering, with a coagulating liquid, for example with the patient's own blood, so that the risk of after-bleeding is eliminated.
Patent CH-653857-A5 (CH)
Title: Erecting chair
Inventor: MEYER BRUNO
IPC: A61G5/14
Filed: 1984-10-22
Abstract: The locking device (53) prevents the seat (17) from ascending quickly in the empty state. In combination with the springs (71, 73) the locking bolt (59) acts as a sensor which detects whether the seat (17) is loaded by a user or not. If the seat is loaded the toothed rack (55) is moved downwards until the toothed flank (83) rests upon the flank (87). Friction between these flanks is then relatively low, so that the steel cable (61) can move the locking bolt (59) counter to the force of the helical spring (71) out of the toothed rack (55) by actuation of the actuation lever (51). However, if there is no-one in the erecting chair (thus, if the seat is unloaded) the spring (27) attempts to push the toothed rack (55) upwards. Due to the forces acting upon the flanks (87, 89) a greater force than that described in the above case is necessary for bringing the locking bolt (59) out of engagement with the toothed rack (55). If the actuation levers (51) are actuated when the chair is empty in each case only the spring (73) is compressed; there is insufficient force which can act upon the locking bolt (59) in order to move the latter. Thus, the seat (17) is reliably prevented from ascending quickly in the empty state. <IMAGE>

Title: Tibio-femoral prosthesis
Inventor: BECHTOL CHARLES O
IPC: A61F2/38
Filed: 1975-05-05
Abstract: The tibio-femoral prosthesis intended to replace the joint surfaces of the tibio-femoral joint, comprises a tibial element (15) intended to be fixed to the upper end of the tibia (47), and a femoral element (13) intended to be fixed to the lower end of the femur (17). The femoral element (13) comprises a lateral condyle and a median condyle used to replace the joint surfaces of the lateral natural condyle (23) and of the median natural condyle (25) of the femur (17). The tibial element (15) comprises a lateral plate and a median plate which are intended to replace the joint surfaces of the natural lateral plate (53) and the natural median plate (55) of the tibia (47). The prosthesis allows the joint to rotate freely without causing pain and without damaging the crural ligament. Furthermore, the prosthesis maintains perfect alignment between the lateral surface and the median surface of articulation of the knee while requiring only a small extraction of bone. <IMAGE>
