Title: Artificial knee joint having improved post and cam structure
Inventor: SUN DOO-HOON
IPC: A61F2/38
Filed: 2009-01-08
Abstract: This invention relates to an artificial knee joint of a PS type having an improved post and cam structure which can replace a natural knee joint. This artificial knee joint, which excludes the posterior cruciate ligament, includes: a femur joint member which is joined to an end portion of a tiber near a femur; a tibia joint member which is joined to an end portion of the femur near the tibia; and a bearing member which is placed between the femur and tibia joint members, wherein the femur joint member comprises the cam and the bearing member comprises the post. In the artificial knee joint, the post of the bearing member and the cam structure of the femur joint member are improved. Therefore, when the femur joint member is slightly rotated from an upper plane to a lower plane at the bearing member, the movement is performed so smoothly that the injury of the post can be minimized. Particularly, when the femur joint member is bent and inserted to a knee through the front depression portion of the post, a more natural rolling movement is enabled. A natural rolling movement is also possible when the femur joint member is completely bent by prevention of collision with the patella. Furthermore, in this artificial knee joint invention which has an improved post and cam structure, when the knee is bent, the displacement of the knee joint can be prevented through the increase of jump distance by placing the front part of the cam of the femur joint member higher than the rest of the cam. Consquently the knee can be bent more completely. For this purpose, the invention provides a PS type artificial knee joint, which excludes the posterior cruciate ligament, includes: a femur joint member which is jointed to an end portion of a tiber near a femur; a tibia joint member which is joined to an end portion of the femur near the tibia; and the bearing member which is placed between the femur and tibia joint members. The bearing member comprises the post formed with a posterior flection and the femur joint member includes the cam where a post contact flection is formed with curvature corresponding to the posterior flection, so that the femur joint member can be rotated on the plane through the contact with the post.

Patent CH-675503-A5 (CH)
Inventor: BERGER FRITZ
IPC: H01H13/12
Filed: 1988-02-01
Abstract: A slide (6), connected to the push-button (3, 4), is supported such that it can move axially in the housing (1). On the housing end facing away from the push-button (3, 4) there is a switching element (17) which contains one or more fixed contact pairs (33) and moving contact supports (27), each of which can be operated by a ram (18 to 20), associated therewith. The ram (18 to 20) is arranged such that it can move in the force path of the slide (6) with respect to the moving contact support (27) and is held in a first position under the influence of a spring (29) and can move into a second position counter to the influence of this spring. This is carried out in such a manner that, when the push-button (3, 4) is pushed, the slide (6) moves the ram (18 to 20) out of the first position into the second position, the ram thereby operating the moving contact support (27). In order to be able to operate the moving contact support (27) without play when the push-button is pressed, it is proposed that a pressure plate (11) be arranged in an overhung manner between the slide (6) and the ram or rams and that each ram (18 to 20) in each case exerts a restoring force on the pressure plate (11) by means of the associated spring (29). As a result of this restoring force, the pressure plate (11) is held in contact with the slide (6) at at least three contact points, the resultant of these restoring forces in the direction of movement of the slide (6) passing through the surface which is limited by the contact points.

Title: Explosive powder-coating installation
Inventor: ZVEREV ANATOLY IVANOVICH
IPC: B05B7/00
Filed: 1979-02-19
Abstract: The installation has an explosion chamber (1), an ignition device (2) for the latter and lines (3, 4) connected to the chamber (1) for feeding the ignitable fuel gas and coating powder. It should be possible to keep the quantity of powder introduced into the chamber (1) constant, in order to maintain the quality of the coating and to avoid loss of powder. For this reason, a carrier gas is used for transporting the powder to the chamber (1). The powder present in the detonation product for coating an object (C) in the chamber (1) is determined (29, 28) for each detonation, and this measurement controls (31) the pressure of the carrier gas. An increase in this pressure gives a higher flow rate per time of flow into the chamber and hence an increased quantity of powder therein. <IMAGE>

Title: Device for separating a stack of flat structures
Inventor: BIZIC MILAN
IPC: B65H3/08
Filed: 1979-12-10
Abstract: A suction head (27) is provided which is movable towards and away from a stack (11). In order to ensure that the topmost flat structure (11') to be lifted from the stack (11) by the suction head (27), when lifted, not only does not displace the second topmost flat structure, but also remains crease-free, a holding down device (32) for the topmost flat structure (11') is allocated to the suction head (27), which holding down device (32) is provided with supporting edges (35, 36) arranged on both sides of the suction head (27). In the process the suction head (27) can be drawn back from a first position in which it projects over the supporting edges (35, 36) into a second position in which the supporting edges (35, 36) project over the suction head (27). Thus, when the topmost flat structure (11') is picked up, a gentle bulging out thereof with respect to the second-topmost flat structure takes place, ensuring neat lifting of this topmost flat structure without displacement of the second-topmost flat structure. The device is suitable in particular for separating stacks of individual sheets of paper or cardboard. <IMAGE>
