Patent number: 6901811Abstract: The invention concerns a device for testing, in a destructive or non-destructive manner, femoral head prosthesis having a blind hole for receiving the end of a femoral prosthesis rod. The device includes a frame provided with a shaft projecting from the frame, said shaft having a substantially complementary shape to said bore and being associated with means for applying a pressure onto the inner bore wall when a femoral head is fitted onto said shaft. This device is characterised in that the shaft includes a sealed jacket having at least one deformable lateral wall portion, and a socket fitted onto said jacket and provided with elastic fingers that extend substantially facing said deformable wall portion of the jacket, and in that said jacket defines an inner chamber in communication with means supplying a pressurized fluid, such that the fluid pressure is transmitted to the inner bore wall via the deformable wall and the elastic fingers.Type: GrantFiled: February 11, 2004Date of Patent: June 7, 2005Assignee: Saphirwerk Industrieprodukte AGInventors: Jean Bäbler, Jürg Burri, Hans Felber, Urs Buntschu, Werner Salvisberg

Patent number: 4915591Abstract: The pump head liner of a small-size precision reciprocating metering pump, which has its application particularly in High Performance Liquid Chromatography (HPLC), is made of transparent material, preferably of synthetic sapphire or monocrystalline zirconium oxide. A pump head casing is designed such that a pump head liner is visually accessible. Cartridge-type check valve units of transparent components are associated with the pump head casing and pump head liner and mounted to be visually accessible. The opening and closing of a ball in a check valve unit can be monitored by an optical sensing system in order to obtain a feed-back signal for governing a control circuitry, having the purpose of compensating the influence of the specific compressibility of the liquid being pumped, upon the pumping efficiency of the displacement system under conditions of high and highest working pressures.Type: GrantFiled: May 9, 1988Date of Patent: April 10, 1990Assignee: Saphirwerk Industrieprodukte AGInventor: Herbert Funke

Patent number: 4572056Abstract: The present invention relates to a plunger or floating piston pump which is particularly adapted for use as a small-size metering pump in performing chemical analyses. In a pump head casing there is disposed a plunger guide bushing made of a ceramic material in which a plunger made of sapphire is slidably guided permanently with extreme accuracy in relation to the bore in an annular seal, said annular seal itself cooperating with said plunger in such a way that there is no clearance between the plunger and said plunger guide bushing. In a modification of the invention, said displacement chamber is formed in a pump head liner which is mounted in said pump head casing. The pump head liner is made of a chemically inert material, preferably of a ceramic material.Type: GrantFiled: November 8, 1984Date of Patent: February 25, 1986Assignee: Saphirwerk Industrieprodukte AGInventor: Herbert Funke
