Title: Proportioning brake valve with dual secondary piston
Inventor: BARTHOLOMEW ROY E
IPC: B60T8/26
Filed: 1987-02-13
Granted: 1990-12-04
Abstract: Abstract of the Disclosure A dual circuit brake valve includes a relay piston (50) having primary (82) and secondary (84) areas which are normally communicated to the pressure level at the primary outlet or delivery port (18).  The relay piston (50) responds to a pressure differential across the relay piston to control communication to the secondary outlet or delivery port (22).  A control mechanism (92) is responsive to a control signal to vent the secondary area (84) to thereby establish a differential area across the relay piston (50), so that the relay piston (50) will establish a pressure level at the secondary outlet or delivery port (22) which is a predetermined fraction of the pressure level at the primary outlet or delivery port (18).

Title: Gas scavenger
Inventor: TAYLOR JERRY A SR
IPC: H01L21/22
Filed: 1987-08-21
Granted: 1990-12-04
Abstract: ABSTRACT          A gas scavenger unit educts gases away from semiconductor wafers as they are withdrawn through a plenum in the scavenger from their processing chamber into the atmosphere.  The scavenger has a peripheral wall which generally defines a plenum having two open ends.  The one end of the plenum communicates with the processing chamber and the other end communicates with the atmosphere.  An exhaust port in the peripheral wall communicates with a house gas exhaust system.  The plenum is divided into two chambers by an aperatured interior wall.  The wafers travel through the first chamber and the second chamber communicates with the house gas exhaust system.  The aperatures in the interior wall are disposed about the wafer travel path so that gases from the processing chamber and/or the atmosphere are educted into the house exhaust system without flowing across the wafers.

Title: Jack device for washing machines
Inventor: ANDERSON JEFF H
IPC: B25B27/14
Filed: 1987-10-06
Granted: 1992-04-28
Abstract: Abstract A jack device employed to extract agitators from the drive shafts of washing machines.  The device includes an annular split ring member having two closed ends and enclosed chamber therein.  The enclosed bladder device expands into a split toroidal configuration.  A tube attached at the periphery and extending from under the agitator to the outside tub is employed to transfer hydraulic or pneumatic pressure into the said device resulting in expansion of the same.  The wall of the bladder is thicker in a zone around the periphery than elsewhere.  This thicker zone prevents the device from ballooning out from under the agitator which would result in failure of successfully removing the agitator from the shaft.

Title: Hydrophilic cellulose product and method of its manufacture
Inventor: GRAEF PETER A
IPC: A61L15/28
Filed: 1987-11-17
Granted: 1991-02-19
Abstract: HYDROPHILIC CELLULOSE PRODUCT AND METHOD OF ITS MANUFACTURE                   ABSTRACT OF THE DISCLOSURE The present invention is a method of making a resilient hydrophilic cellulosic pulp particularly suitable for conversion into an absorbent fluff for products such as disposable diapers. The process involves treating a wet or partially dried cellulosic fiber web with an aqueous solution of a glycol and dialdehyde. Glyoxal and propylene glycol are preferred materials. These are desirable sprayed on a wet or only partially dried sheet at some convenient location on a conventional paper machine. This location is not critical, but a point about midway through the press section has given excellent results. The treated sheet is then dried conventionally. There is no need for the use of any catalysts or for a prolonged curing step at elevated temperatures. The products of the invention are characterized by a much increased absorbency rate and by a somewhat higher water holding capacity. The sheets also require less power for milling into a fibrous fluff. Knots or fiber clumps are reduced and there is no significant increase in fiber fines due to embrittlement of the treated pulp product. The invention further includes the products made using the present method.

Granted: 1994-01-18
Abstract: ABSTRACT OF THE DISCLOSURE 1-N-substituted-6-halo-1,4-dihydro-4-oxo-7-piperazino-quinoline-3-carboxylic acids,  useful in feed additives and as antibacterial agents, for example, ciprofloxacin, are prepared in a two-step reaction, from the corresponding 7-halo-quinoline-3-carboxylic acid.  In the first step, the starting material is reacted with a N-alkoxycarbonyl substituted piperazine, which forms an intermediate compound which is substantially insoluble in the reaction medium, and consequently precipitates out in pure form. Then this intermediate is hydrolysed, to remove the N-alkoxycarbonyl group, and yield the piperazino free base.
