Patent CA-2128426-A1 (CA)
Title: Fuel injector nozzles
Inventor: CALEY DAVID J
IPC: F02M61/08
Filed: 1993-02-17
Abstract: An injector nozzle for a fuel injected internal combustion engine having a selectively openable nozzle for the delivery of fuel to the engine combustion chamber, the nozzle comprising a port (17) having an internal annular surface and a valve member (13) having an external annular surface coaxial with respect to the internal annular surface of the port (17). The valve member (13) being axially movable relative to the port (17) to selectively provide an annular passage therebetween for the delivery of the fuel or sealed contact therebetween to prevent the delivery of fuel. The valve member (13) has a coaxial projection (30) extending beyond the extremity of the external annular surface and positioned so the fuel plume issuing from the nozzle will follow a path based on the external surface (33) of the projection (30) and will pass therealong that external surface (33), to issue from the lower extremity thereof in a substantially coaxial relation to the nozzle. The projection (30) preferably is necked down immediately adjacent the valve member (13) and thereafter is of a converging circular shape, generally of an inverted truncated conical shape.   The projection (30) provides a surface (33) which aids in the control of the fuel plume shape and corrects disturbances to that shape caused by deposits in or on the surface of the nozzle port (17) or valve member (13).

Title: Process for the preparation of polyacetals
Inventor: HOFFMOCKEL MICHAEL
IPC: C08G2/00
Filed: 1994-08-12
Abstract: Abstract Process for the preparation of polyacetals Process for continuous preparation of homo- and copolyoxymethylenes with stable end groups in a homogeneous phase, in which in a tubular reactor with static mixing elements cyclic formaldehyde oligomers are polymerized in the presence of protonic acids as initiators in amounts of 0.005 to 500 ppm in a polymerization zone, in which the residence time of the reaction components in this zone is 0.1 to 10 min and in which the initiator is deactivated immediately after polymerization, there being a fluid transition between the polymerization and deactivator zones which is determined solely by the addition of deactivator, and in which, besides deactivation, stabilization of the chain ends is carried out in the presence of residual monomers, with the volatile constituents being removed from the reaction mixture in a subsequent vent unit. Stabilization is carried out in the presence of alkaline substances, either at temperatures of 150°C to 250°C, if necessary in the presence of water or primary alcohols, or at 175°C to 250°C in the absence of these additives.
Patent CA-2132343-A1 (CA)
Title: Case-mounted rlg readout having block mounted optical sensor
Inventor: THORLAND RODNEY H
IPC: H01S3/083
Filed: 1993-12-07
Abstract: A readout device is provided for use in a ring laser angular rate sensor assembly which has improved low rate performance. Low rate performance is improved by reducing sources of backscatter thus not allowing light to be reflected back into the optical signal carrying medium. Backscatter is reduced by placing the optical sensors (62, 64) directly upon the gyro output mirror (14), thus causing the optical sensors to be dithered along with the laser block (10). By dithering the optical sensors, any backscatter caused by these elements is dealt with by dithering. While the optical sensors are dithered, the readout apparatus (44) continues to utilize the advantages of a case mounting.
