The device also includes at least one sealing member is arranged to seal the portion of tube and the portion of bore in a position between the locking assembly and the piercing end so as to leave the mating surfaces downstream including the locking assembly substantially cleansed of the flowable material.
Patent CA-2361030-A1 (CA)
Inventor: TAKEUCHI ESTHER S
IPC: H01M4/66
Filed: 2001-11-05
Abstract: A new sandwich cathode design having a first cathode active material of a relatively low energy density but of a relatively high rate capability sandwiched between two current collectors and with a second cathode active material having a relatively high energy density but of a relatively low rate capability in contact with the opposite sides of the two current collectors, is described. The present cathode design is relatively safer under short circuit and abuse conditions than cells having a cathode active material of a relatively high energy density but a relatively low rate capability alone. A preferred cathode is:      CF x/current collector/SVO/current collector/CF x. The SVO provides the discharge end of life indication since CF x and SVO cathode cells discharge under different voltage profiles. This is useful as an end-of-replacement indicator (ERI) for an implantable medical device, such as a cardiac pacemaker.
Patent CA-2364548-A1 (CA)
Title: Food product which artificially has been given a cell-like structure by coextrusion of several components, and method and apparatus for manufacturing such food product
Inventor: RASMUSSEN OLE-BENDT
IPC: A23P1/12
Filed: 2000-04-13
Abstract: Two or more different materials, especially food materials, are coextruded through adjacent orifices of an extruder. The flows of the two materials are cut in a direction transverse to the flow to form segments of flow. These segments are interspersed so as to join upstream and downstream of each segment of first material to a segment of a second material. Generally two rows of joined segmented flows are extruded side by side. Preferably between the two rows is formed a boundary cell wall which usually is transformed to a harder material after extrusion.  Cell walls of the harder material may surround, in two or three dimensions, cells of softer or foamed material. Co-extrusion is carried out by a method in which the dividing members which segment the flows move across the extruder orifices in rhythm with the imposition of extrusion pressure on the material through the respective orifice. The dividing members may reciprocate or rotate relative to the orifices. Preferably the dividing members are fixed and the orifices are caused to move. In this case, the material may be supplied from respective reservoirs in fixed dye components, to the moving portion. The process and apparatus is particularly useful for producing confectionary products, for instance formed of chocolate, marzipan, or dough materials.
