Title: Process for the preparation of alkylphosphonous acid diesters and/or dialkylphosphinous acid esters
Inventor: SCHEFFEL GUNTER
IPC: C07F9/48
Filed: 1990-04-06
Abstract: The abovementioned compounds are prepared by reacting trialkyl phosphites with phosphorus trichloride and/or monoalkyl esters of dichlorophosphinous acid at -20 to +100 DEG C followed by immediately reacting the product with alkylmagnesium chloride or alkylmagnesium bromide at -60 to +50 DEG C, followed by removing the desired compounds from the distillate of the volatile compound. This allows dialkyl esters of alkylphosphonous acids and monoalkyl esters of dialkylphosphinous acids to be obtained without complicated and costly purification of intermediates. The phosphorus-containing esters obtained, in turn, are valuable intermediates, for example for the preparation of flameproofing agents and crop protection agents.

Patent CA-2019439-A1 (CA)
IPC: G01F1/66
Filed: 1990-06-20
Abstract: A mass flow meter working on the Coriolis principle comprises at least one measuring tube (1) at least two energy converters (4, 5) acting as oscillation exciters  (S)  or oscillation  detectors (M) and an evaluating circuit (24) for determining the mass flow.          Waves are produced which travel in and against the direction of flow (X) along the measuring tube (1).    At least one measuring path (A1) serves to find the speed of travel in and against the direction of flow.    The evaluating circuit (24)  determines the mass  flow utilising the  difference  between  the  two  speeds  of travel.   In particular, the difference of the times of travel of the waves can be  processed  in  the  evaluating circuit.     This leads to a measurement independent of a departure from the zero point and of a current profile.

Title: Liquid dispensing system and packaging apparatus which includes such a system
Inventor: QUINN THOMAS P
IPC: F17C9/00
Filed: 1990-08-31
Abstract: ABSTRACT A liquid dispensing system and a packaging apparatus which includes such a system has a chamber 6 of a chryogenic vessel 2 containing a reservoir of liquid gas 1 (such as nitrogen,  oxygen or argon) which is to be dispensed in doses 26 through an outlet port 12 which is in constant communication with a sub-chamber 17.   The sub-chamber 17 is part of a piston 16 and cylinder 1.5 device in which the piston is reciprocated by means 21 and 24 to expand and contract the sub-chamber.   When the sub-chamber 17 is expanded, liquid gas enters from the reservoir 1 through flow ports 18 which are closed by the piston 16 during contraction of the sub-chamber to dispense a dose 26.   Mounted beneath the outlet port 12 is a tubular skirt 25 having internal passages 30 through which purging gas is directed into the region 29 adjacent to the outlet port 12.    The region 29 is purged of air to alleviate ice build-up at the outlet port 12.   The purging gas liquifies at a temperature not greater than the temperature of the liquid gas at the outlet port and provides a back-pressure at the outlet port to restrain flow of liquid gas therethrough prior to the contraction of the sub-chamber 17 to dispense a dose.     The doses 26 are dispensed into open topped containers 34 that are moved successively beneath the outlet port 12 and means 50 is provided for sensing the containers and controlling  the  devices  21  and  24  to  maintain synchronisation between the dispensing and the movement of the containers.

Abstract: Abstract of the Disclosure Connectors for optical cables in ribbon form and a process for making such connectors in which metal plates for the enclosing the cable ends are made by cold, plastic flow forming of grooves in the plates with a punch having ridges produced by a process which produces grooves which hold the positions of the optical fibers between the plates within narrow tolerances.  In the process, a punch body with partially formed ridges is mounted on a head rotatable about the axis of the body and movable toward a grinding wheel which is movable in a path perpendicular to the direction of movement of the head toward the grinding wheel.  After two opposite passes of the grinding wheel along the side of a ridge, the punch body is rotated 180 degrees, and the side of a corresponding ridge on the opposite side of the punch body axis is ground.  The process is repeated with movement of the head toward the grinding wheel, which is measured, until the sides of all ridges are ground.  One of the grooves receives an alignment pin, and after the fibers are assembled with the plates, the end faces of the fibers are ground.

Abstract: An onboard instructor station for a training device provides a human/computer interface that is designed to support an optimum instructor's scan pattern of the training scenario.  All displays and switches required to control and monitor the mission are resident at the instructor's work surface directly in front of, and tangent to the instructor's seated position.  This design allows for a dedicated over-the-shoulder observation position.  Therefore, the instructor may simultaneously observe trainees' actions, a visual scene and device instrumentation while controlling and monitoring the training environment through embedded situational awareness displays and corresponding switches at the work surface.  The unique aspect of this design is the one position from which all tasks can be accomplished through the support provided by the packaging.  This packaging employs flat panel displays which replace the traditional, larger CRT units.
