Title: Draft gear for railroad car coupler system
Inventor: CARLSTEDT RICHARD A
IPC: B61G9/10
Filed: 1985-12-09
Granted: 1990-05-22
Abstract: DRAFT GEAR FOR A RAILROAD CAR COUPLER SYSTEM ABSTRACT A draft gear to absorb and cushion impacting forces on a railroad car coupler system includes a spring package in an inner section of a housing of the gear, The spring package connects with a set of friction shoes carried in friction shoe seats formed in an outer friction bore sec-tion of the housing. The shoes in turn engage with a wedge which extends from the housing outer end. In each friction shoe seat is a grooved recess having an inner, outer, and connecting groove portion arranged in an H-like shape. In each grooved recess in turn is a metallic insert to provide a film of lubricant between the shoes and friction shoe seats respectively. During operation the impacting forces on the coupler system drive the wedge and shoes inward to compress the spring package. This movement is restrained by friction between the shoes and friction shoe seats. Because the inserts are rigid, insert material in the outer groove portions is not readily dislodged, if the shoes move sufficiently inward to expose the outer groove portions. Thus, the coefficient of friction between the shoes and friction shoe seats remains properly regulated to insure continued effective frictional restraint. Additionally, the shoes are inhibited from being stuck when the draft gear is in a compressed state.

Title: Optical system for wide angle ir imager
Inventor: NOBLE MILTON L
IPC: G01J1/42
Filed: 1987-01-09
Granted: 1991-09-10
Abstract: OPTICAL SYSTEM FOR WIDE ANGLE IR IMAGER                 ABSTRACT OF THE DISCLOSURE           The invention relates to a high performance optical system for a wide angle IR imager requiring a cryogenic environment for the IR detector array.  The wide angle requirement makes it necessary for one lens to be behind a "cold aperture" within the cryogenic environment where focusing is difficult and performance of the aperture reduced.  These objectives are minimized by use of a telecentric lens pair, one member of which is within the cryogenic environment.   The telecentric lens pair refocuses the primary image formed by an objective lens, permiting a high quality image to be formed on the IR detector array.  The usual errors in positioning the internal lens, which might impair the quality of the focused image, are avoided by a compensatory repositioning of the externally accessible objective lens.  The use of collimated bundles of light, characteristic of telecentric lens pairs, permits maximum aperture efficiency, and also provides a fourier transformation plane in which spatial filtering may be used to reduce IR background of low spatial frequency.

IPC: C07C31/04
Filed: 1987-10-21
Granted: 1991-02-19
Abstract: Abstract A method of preparing methanol consists in that a synthesis--gas containing carbon oxides and hydrogen is passed through a fixed bed of a copper-containing catalyst under pressure 30.0-15.0 MPa at a temperature of from 150 to 300°C. The catalyst is divided into two parts either in an equal proportion or in a smaller/greater ratio equal to 0.5-1. The gaseous mixture obtained after passing the first part of the catalyst bed is stirred prior to the supply thereof to the second part of the catalyst bed. As a result the reaction mixture is formed con-taining the aim product. Each subsequent direction of passing the synthesis-gas through the catalyst bed and that of removing the reaction mixture are changed to opposite with respect to the previous direction.

Granted: 1993-06-01
Abstract: ABSTRACT      An analytical test strip has a flexible blister (12) thermoformed in a sheet plastics member (22), and a diaphragm (34) which closes the blister to create a reservoir for holding a reagent and/or carrier liquid (32). The sheet plastics member (22) is further formed with one or two spikes (28) the or each of which is disposed within the blister and extends in a reentrant manner towards the diaphragm where it terminates at a point.  For use of the dispenser the blister is pinched by finger pressure applied by the user to cause the spike or spikes to puncture the diaphragm and release the reagent and/or carried liquid which then soaks along an absorbent layer (40) until it reaches a viewing window (20).  The test substance, particularly a liquid, is applied to the absorbent layer at a cavity (16), and combines with the reagent and/or carrier liquid as it moves to the viewing window.  If required, the absorbent layer may include one or more discrete areas or bands (44) of an absorbed reagent substance through which the reagent and/or carrier liquid and the test substance pass.  The medical (or other) condition for which the test is being made is shown as a colour or tone change of the absorbent layer as seen through the viewing window.
