Title: Emergency exit door latch
Inventor: LOGAN EMANUEL L

Granted: 1983-10-18
Abstract: EMERGENCY EXIT DOOR LATCH WITH HYDRAULIC RETARDATION OF BOLT RETRACTION Abstract of the Invention An emergency exit door latch includes a pivoted bolt which pivots into registration with a keeper and is urged in the projected position by a spring biased plunger.  The spring biased plunger is retained within a hydraulic cylinder.  Hydraulic lines connect the portion of the hydraulic cylinder in front of the plunger to the portion behind the plunger through a throttling means.  Upon pressing against the door, the swinging bolt urges the plunger rearwardly so as to force fluid in the rear portion of the hydraulic cylinder through the line and the throttling means to the front portion of the hydraulic cylinder thereby allowing the bolt to slowly retract as the fluid is throttled.           Preferably, a push bar is provided having a detent means thereon which locks the bolt in its projected position.  Upon pressing the push bar, the bolt is released so that it can be slowly retracted as pressure is placed on the door.           Preferably, there is an emergency release system which allows rapid transfer of fluid from the rear of the piston to the front of the piston upon the occurence of an emergency condition such as tripping of a fire alarm or smoke alarm.  This emergency system allows the hydraulic fluid to bypass the throttling device which generally retards retraction of the bolt.         An alarm system is connected to the latch and sounds whenever the latch is operated so as to alert personnel within the building that someone is trying to open the emergency door without authorization.

Abstract: ABSTRACT OF THE DISCLOSURE       An aircushion and fluid film bearing arrangement particularly suitable for supporting the undersurfaces of the outer edges of the transport belt in a horizontal belt vacuum filter is disclosed wherein the respective air box sections beneath the edges are fabricated into parallel members each exteriorly rectangular in form and having an air pressure chamber therein triangular in cross-section with its apex forming a longitudinal slot centrally disposed in the flat upper surface of the box, which slot communicates the air pressure admitted to the chamber to the upper surface of the box.  Longitudinal sealing guides are upstandingly mounted on the upper edges of each air box and form fluid-pressure chambers above the flat upper surfaces in cooperation with the undersurface of the transport belt, which chambers con-tain the communicated air pressure and create a fluid cushion  exerting  evenly  balanced  supporting  forces across the outer undersides of the belt. In addition, the sealing guides have flat upper surfaces above which fluid film air bearings are formed which restrict edge leakage of the air from the fluid cushion while preventing direct contact of the belt undersurface with any parts of the air boxes.

Abstract: Abstract of the Disclosure There is disclosed printing apparatus having a pivotally mounted print head which cooperates with a platen, a cam shaft to which a cam is secured for actuating the print head  and to which another cam is secured for driving an  operating a lover   The operating lever is coupled to a slide which drives a feed finger and cam means for actuating an inker.   The travel  of the feed finger is selectively variable by changing the position of the pivot on which the lever is mounted.  The cam means is part of a lost-motion connection which couples the slide to the inker.  As the operating lever is cammed in one direction to move the feed finger forward,  the inker is moved into and out of inking cooperation with the  print head assembly   Because of the lost-motion connection adjustment, of the pivot does not affect the length of travel of the  inker.   When the inker is in inking position the inker is supported at both sides of the platen thereby leaving the platen accessible during threading of the  apparatus with the web of record member.   The print head assembly  includes  a pair of print heads, each print head having at least one series of rotatably mounted drive wheels  and a support.   A plurality of printing bands having different printing elements are trained  about the support and respective drive wheels.   Each support of each print head is adjustable by exerting forces at opposite ends of the support so that all the  printing elements at the support are disposed in a common plane parallel to the platen.   The print heads are rigidly interconnected by plates.  Set screws threadably received by one of the plates are accessible from about the  print head and act on adjusting plates which exert forces at opposite ends of the respective supports.

Abstract: Improved Method of Heat Recovery from Internal Combustion Engines for Supplementary Power ABSTRACT:           Nearly two thirds of the fuel energy consumed in internal combustion engines is expelled as heat in the exhaust gases and coolant. The lower temperature portions of this heat can be upgraded by a heat pump cycle to produce steam which can then be superheated by the higher temperature portion of the exhaust gases. The current pro-posal for achieving this can be improved by superheating the boiler into two sections; directing the high temperature portion of the exhaust gases into the superheating boiler; and conducting the low temperature portion of the exhaust gases through a heat exchanger in the low temperature boiler; and conducting a controllable portion of the exhaust steam from a driven turbine through the second stage, instead of the first stage of the heat pump cycle.
