Title: Multiple-core optical connector and its manufacturing method
Inventor: SATO ETSUZO
IPC: G02B6/38
Filed: 1997-07-31
Abstract: The invention relates to a small-sized multiple-core optical connector having high reliability, which can be easily assembled and manufactured. A plurality of array guide grooves (22) are arrayed and formed on a flat substrate (21). The array pitch interval of the array guide grooves is roughly coincident with the outer diameter of bare optical fibers (4a), (4b). The first optical fiber tape (6a) and the second optical fiber tape (6b) are disposed at the rear end side of the flat substrate (21) so as to overlap each other, wherein the first bare optical fibers (4a) of the first optical fiber tape (6a) and the second bare optical fibers (4b) of the second optical fiber tape (6b) are alternately array-converted and accommodated in the array guide grooves (22). The bare optical fibers (4a), (4b) are pressed from the upside of the bare optical fibers (4a),(4b) at the tip end side of the array, and they are placed and fixed in the array guide grooves. A filter insertion groove (17) is formed in the direction crossing the corresponding array guide grooves (22) at an area where the array guide grooves (22) are formed, a filter (16) is inserted into the filter insertion groove (17), and the filter (16) is attached to each of the second bare optical fibers (4b) at the second optical fiber tape (6b) side.

Title: Thermoplastic foam and process for producing it using carbon dioxide
Inventor: GUSAVAGE GERALD G
IPC: C08J9/00
Filed: 1996-12-18
Abstract: The present invention provides a process for producing thermoplastic foam, including: (a) melting a thermoplastic polymer to produce a polymer melt; (b) introducing a carbon dioxide blowing agent into the polymer melt; (c) adding to the polymer melt one or more additives selected from the group consisting of (1) polysiloxane, and (2) mineral oil;  and (d) extruding and foaming the melted polymer melt, blowing agent, and one or more additives to produce thermoplastic foam. The resultant thermoplastic foam can be thermoformed into various foamed articles, such as foam packaging trays. The quality of foams made from a carbon dioxide blowing agent, and particularly 100 % carbon dioxide, has been found to be substantially improved by adding one or more of the foregoing additives, i.e., polysiloxane, mineral oil and, optionally, polyolefin to the polymer melt during the extrusion and foaming process. Such foams have far less ruptured cells, surface cracks and corrugation than comparable foams made with a carbon dioxide blowing agent but which lack the additives of the present invention.

Patent CA-2249685-A1 (CA)
Inventor: KUIVAMAEKI ISMO
IPC: F16F15/129
Filed: 1998-10-07
Abstract: The invention relates to a load brake comprising a load shaft (4), a flange-likepressure plate (18) fixedly mounted onto the load shaft, a cogwheel (19) arranged on the load shaft with tension means (20, 21) which produce an axial motion and force in the cogwheel as the wheel rotates with respect to the load shaft, a ratchet wheel (22) mounted between the pressure plate (18) and the cogwheel (19), a pawl (23) for preventing the rotation of the ratchet wheel at least in the release direction of the load shaft (4), friction surfaces (28, 29)provided between the pressure plate (18) and the ratchet wheel (22), and the ratchet wheel and the cogwheel (19), whereupon rotation that tends towards the release direction of the load shaft (4) and that is faster than the speed ofrotation of the cogwheel (19) brings the pressure plate (18) and the cogwheel (19) closer together in the axial direction and presses them against the ratchetwheel (22), which results in the braking of the rotational motion of the load shaft (4), whereas rotation that occurs in the release direction of the load shaft (4), that is directed at the cogwheel (19), that exceeds the braking torque and that is faster than the speed of rotation of the load shaft removes the pressureplate (18) and the cogwheel (19) further apart in the axial direction and thus unlocks the braking connection of the pressure plate, the ratchet wheel and the cogwheel. In order to improve the properties of braking, means (30) are provided in connection with one friction pair (22, 19) of the friction pairs formed by the pressure plate (18) and the ratchet wheel (22), and the ratchet wheel (22) and the cogwheel (19), and these means produce an axial preclamping force that presses the elements of the friction pair together.

Title: An oil filter to introduce anti-wear additives into engine lubricating system
Inventor: VOIGHT ROBERT FRANKLYN
IPC: B01D35/02
Filed: 1997-08-01
Abstract: An oil filter (10) includes a colloidal suspension (12) of PTFE particles less than 2 microns in size retained by capillary forces within the intricacies of the filter media (26) until the filter (10) is installed and engine oil flows at first engine start up following installation. The PTFE colloidal suspension (12) is completely and immediately released into the engine lubricating system when oil flow is initiated. The PTFE colloidal suspension (12) is introduced into the oil filter (10) as one of the last manufacturing steps. Oil filter (10) is disposed vertically with its outlet port (14) at the top. A quantity of the PTFE colloidal suspension is introduced into the outlet port (14) to initially fill a portion of the volume defined by a centertube (18) and a retainer (16). The PTFE colloidal suspension passes through openings (20, 24) into contact with filter media (26). The capillary forces acting between filter media (26) and the PTFE colloidal suspension (12) cause the colloidal suspension (12) to be drawn in and retained within the intricacies of the filter media (26) fibers.
