Abstract: INVENTORS John Richard Cary Walter Herbert Wesner By Thomas W. Brennan TITLE: IMPROVEMENTS IN MANUALLY OPERATED LIQUID DISPENSERS ABSTRACT OF THE DISCLOSURE: A manually operated dispensing device for a container holding a quantity of liquid is disclosed. The device has a variable volume pump chamber within a component retaining body. The chamber is defined by a flexible walled, collapsible container having a closed end or bottom and an open end or top preferably in the form of a compressible bellows, and fabricated of any of the various thermoplastics. The container or bellows is associated with a movable member in the form of a trigger which when actuated compressively stresses the container in a direction to reduce its length and the volume of the chamber therewithin. When the compression stress applied by the actuating member or trigger is relieved or removed, the container regains its original size and shape and returns the actuating member to its initial position. Associated inlet and outlet valves and respective conduits are also incorporated in the device whereby liquid in the liquid container is drawn into the chamber and pumped through a discharge nozzle in the form of a spray, as desired. The alternate application and relief of compressive stress by the trigger or operating member also opens and closes the valves so that liquid can be drawn into the chamber and dispensed therefrom.

Abstract: SEALING ARRANGEMENT FOR HIGH VOLTAGE FUSE         ABSTRACT:  A sealing arrangement for a high voltage fuse comprises a round metal plate that has a center portion that has been machined to reduce the thickness of the center portion.  The center portion of the metal plate is then subjected to a coining or pressing operation to further reduce the thickness of the center portion and also to increase the hardness and smoothness of the center portion so that the center portion can be reliably punctured during fuse operation.          The metal plate is then sealed over the end of the fuse by folding the edge of a metal conducting tube over the edge of the metal plate.  The peripheral portion of the metal plate serves as a stop to prevent the expulsion of fuse parts when the fuse operates.

Abstract: ABSTRACT OF THE DISCLOSURE         An opto-electronic transducer for determining position and/or velocity of one member with respect to another member is provided with light amplitude control.  The transducer is comprised of a scale with a trans-mission grating on a first track and an indexing bar near each end of a sec-ond track adjacent the first, and a reticle with two sections of the same grating, one section being offset spatially one quarter cycle with respect to the other section for producing quadrature signals through two photosen-sors opposite the first track from which relative position and/or velocity between the reticle and the scale can be determined.  A slit is provided in the reticle in order to provide information for determining position relative to the indexing bars.  A single photosensor opposite the second track is used both to detect the indexing bars and to provide a feedback control signal to maintain the amplitude of light illuminating the scale and reticle constant.

Abstract: ABSTRACT         A method and a machine for continuously transferring starting sheets for the electrolytic refining of metals, particularly copper, from the horizontal into the vertical position for introduction into a stand in which the starting sheets are stored for subsequent suspension at equal intervals in the electrolytic refining baths.  The sheets are taken up by cathode bars attached thereto and are advanced continuously at a substan-tially uniform speed along a path of movement which changes continuously from the horizontal to the vertical.  The sheets are successively raised over the transition in the path of movement from the horizontal to the vertical.  Moveable supports in the form of rollers secured to endless chains provide support for the sheets during their transition from a horizontal to a vertical position.

Abstract: HEAD PRESSURE CONTROL SYSTEM  FOR REFRIGERATION APPARATUS                  ABSTRACT OF THE DISCLOSURE       Constant condenser pressure is maintained in an air-cooled condenser of a refrigeration system which operates at either full capacity or reduced capacity depending on the heat load requirements.  When operating at full capacity, the condenser head pressure will be held generally constant at a relatively high control point even in the presence of wide variations in condenser cooling air temperature.  On the other hand, when the heat load requirements decrease and the refrigeration system switches to its reduced capacity operating mode, the control point automatically drops to a substantially lower level, whereupon the condenser pressure is maintained relatively fixed at that lower control point despite major changes in the condenser cooling air temperature. By automatically lowering the control point at reduced system capacity, maximum efficiency and economical operation are obtained.

Title: Safety closure cap
Inventor: COOKE CARL W
IPC: B65D50/04
Filed: 1978-10-30
Granted: 1982-02-09
Abstract: ABSTRACT This invention relates to closures for containers, and more particularly to "safety"  closures having a locking feature so that when sealingly engaged on a container, the cap is locked thereon and can be removed only by special manipulation.  A significant problem encountered with prior art safety closures is that when employing a multiplicity of projections,  or lugs, as the locking means it has been found that they can often be easily sheared , thus neutralizing the effectiveness of the safety locking feature.  Also, in some prior art designs, it is necessary that the projection and the closure be formed from a resilient material to permit the closure to be urged into and out of its locked position.  Such de-signs are unsuitable for use with metal, glass, rigid plastic, or the like.  In the closure of the present invention,  at least three enlarged members are equiangularly spaced about the closure thread and form locking shoulders adapted to interengage corresponding shoulders defined on the thread of the container to lock the threads together and prevent removal of the closure except by special manipu-lation.  A resilient liner is compressed when the closure is drawn down on the container and the compressed resilient liner urges the cap upwardly and maintains the shoulders in locked engagement.

Abstract: ABSTRACT OF THE DISCLOSURE         Stacking apparatus for stacking sheets being fed thereto at high speed along a feed path.  A base is positioned a spaced distance below the feed path of the documents.  A stacker plate is arranged above the base with its upstream end positioned above the feed path and the downstream end adapted to rest upon the base at a spaced distance from the end of the base lying beneath the stacker plate.  The stacker plate is curved to include an upstream concave portion and a downstream convex portion confronting the documents to guide the leading edge of the documents along the bottom surface of the plate downwardly towards the downstream end of the plate to be stacked on the base beneath the downstream end of the plate.  Means are provided for swingably mounting the upstream end of the plate to enable the downstream end to move upwardly as the height of the stack increases.  The stacker plate further includes an end wall at the downstream end for limiting movement of the sheets in the feed direction.  Rebound prevention means are provided on the stacker plate for preventing sheets striking the end wall from rebounding therefrom.
