Inventor: TRUTTMANN PETER
IPC: B21D28/12
Filed: 1997-05-16
Abstract: A method is disclosed of manufacturing a plurality of identically shaped articles from a sheet or web of material. The method includes the steps of forming a sheet or web of material out of one or more layers and then cutting the sheet or web into a plurality of identically shaped articles and a plurality of trim waste members. All of the articles are oriented in the same direction and no part of any article overlies another article. Each of the articles has an outer periphery with at least four spaced apart peripheral segments. Each of the peripheral segments abut against a portion of the periphery of a different adjacent article. The method also requires that when the articles are cut from the sheet or web of material that the ratio of trim waste members to articles is at least 2:1.

Patent CA-2212258-A1 (CA)
Inventor: JONES SHEDRICK D
IPC: A61F2/46
Filed: 1997-07-31
Abstract: The invention is a method and apparatus for embedding an implant of a special design in bone tissue in a way that encourages bone tissue growth in and around the implant thereby achieving greater attachment security over longer periods of time. The user employs a bone-fragment collecting drill to form the bone-tissue hole and deliver the resulting bone fragments to a collecting region. The user crumbles the bone fragments by placing them in the lower of two mating spoon-shaped jaws of a pliers-like device and repeatedly opening and closing the jaws until the bone fragments are crumbled. The surface of the implant is equipped with one or more embedded helical channels and through-holes to permit bone growth into the implant. The installation of the implant consists of partially filling the bone-tissue hole with bone crumbs, packing the helical channels and through-holes with bone crumbs, and installing the implant in the bone-tissue hole. The interspace between the implant and the bone tissue becomes filled with the patient's own bone tissue during the installation process thereby greatly encouraging the growth of bone tissue in and around the implant.

Patent CA-2238916-A1 (CA)
Title: High pressure feed pump
Inventor: SPINNLER FRITZ
IPC: F02M59/48
Filed: 1998-05-28
Abstract: The high pressure feed pump (14) has a plunger cylinder (26) and a cylindrical plunger piston (28) moved back and forth therein. The plunger cylinder (26) and the plunger piston (28) delimit a feed space (24) which, in the case of a filling stroke (F) of the plunger piston (28), can be connected via a filling valve (24) to a supply space for a feed medium. Furthermore, in the case of a feed stroke (F') of the plunger piston (28), the feed space (24) can be connected via a delivery valve (42) to a high pressure space. The plunger cylinder (26) is of essentially rotationally symmetric design and is surrounded with a press fit by a pressure body (44). The external prestress exerted by the pressure body (44) on the plunger cylinder (26) relieves the latter of high stresses when the pump is to generate extremely high pressures.
