Abstract: A.C. POWERED SPEED UP CIRCUIT                   ABSTRACT OF THE DISCLOSURE An improved speed up circuit, especially useful with high speed, push pull circuits, is disclosed.  This uses only A.C. power to discharge the interelectrode and depletion capacitances of an output transistor thereby eliminating uncontrolled shunt current from the output to ground through the output transistor thereby allowing the output to reach the desired level in a shorter period of time.  These desirable results are accomplished by capacitively coupling a resistor-transistor speed up circuit to the base of the output transistor to actively pull the base of the output transistor to ground and discharge the inherent interelectrode and depletion capacitances of the output transistor.

Abstract: MODULAR TYPE GUIDED BEAM FLAT DISPLAY DEVICE            Abstract An evacuated envelope has a rectangular display section and a gun section at one edge of the display section. The display section includes front and back walls which are generally rectangular, in closely spaced, parallel relation, and a plurality of spaced, parallel support walls between the front and back walls forming a plurality of parallel channels.  The gun section extends across one end of the channels and includes therein gun structure which will direct electrons into the channels.  In each of the channels is a beam guide which confines the electrons in a beam and guides the beam along the length of the channel.  The beam guide also includes means for selectively deflecting the electron beam out of the guide at selective points along the guide so that the beam will impinge upon a phosphor screen along the inner surface of the front wall.  In each of the channels is a scanning deflector which deflects the path of the beam as it passes from the guide to the phosphor screen so that each of the beams will scan a portion of the phosphor screen.  The beams in each channel are scanned transversely across its portion of the screen in a trans-verse direction opposite to that of the beams in the adjacent channels.

Abstract: STERILIZED STORAGE CONTAINER           Abstract A container is provided having a base and a lid with the base being formed relatively flat but with the center portion of the base raised so that condensation within the container will flow to the edges and out of the container when the lid is not in a closed position.  The lid is held partially open by an actuator pin connected to an expandable chamber which will expand in response to the pressure drop at the end of the sterilizing cycle to withdraw the pin and allow the lid to close onto the base. In this way, the container is closed after the contents have been sterilized and after any condensation within the container has been allowed to drain, but before the container is exposed to unsterile environment.  A valve controlling the flow of steam into the expandable chamber closes when subjected to the high temperature steam, thus capturing the steam which eventually expands to cause withdrawal of the pin. The container lid and base together with a gasket permit steam to be withdrawn from the container but prevent air flow into the container once the lid is closed.  A vacuum created within the container at the end of the sterilizing cycle holds the container lid in place.        In another arrangement, an expandable chamber is em-ployed to cause the container to be sealed at a predetermined pressure after the container has been subjected to a final vacuum in an autoclave cycle but before the container is removed from the autoclave. The lid is first held open by one end of a pivotally mounted lever. A temperature triggered, pressure re-sponsive expandable chamber is employed to pivot the lever, withdrawing the end of the lever which had been supporting the lid and pivoting the second end of the lever into lid supporting position.  When the pressure surrounding the expandable chamber is increased at the end of a vacuum cycle in an autoclave, the expandable chamber contracts, allowing a spring to pivot the lever and withdraw the second end of the lever from supporting the lid, thus allowing the lid to fall and seal on the base.

Abstract: A CONTROL FOR A TWO STAGE MASTER CYLINDER              ABSTRACT OF THE DISCLOSURE A two stage master cylinder having a bore with a first diameter and a second diameter separated by a shoulder.   A first piston is located in the first diameter of the bore to establish a first chamber.  A second piston has a first section located in the first diameter of the bore to establish a second chamber and a second section located in the second diameter of the bore to establish an actuation chamber therein.  A first passage in the second piston connects the actuation chamber with the second chamber.  A second passage in the second piston connects the first passage to a reservoir in the housing.  A shuttle piston located in the first passage has a first surface area exposed to the second chamber and a second smaller surface area exposed to the actuation chamber.  A spring urges the shuttle piston toward the second chamber.  An input force from an operator moves the second piston causing fluid to flow from the actuation chamber through the first passage to the second chamber.  The first section of the second piston acts on actuation fluid and the operational fluid in the second chamber and the first piston acts on the operational fluid in the first chamber to provide the front and rear wheel brakes with a braking signal. The operational fluid in the second chamber acts on the first surface of the shuttle and overcomes the spring to establish communication of between the actuation chamber and the reservoir through the second passage.  Thereafter, the entire input force from the operator acts on the first section of the second piston to pressurize the operational fluid in the first and second chambers in the generation of the braking signal.

Abstract: TITLE               AN OPTICAL SYSTEM FOR VISUAL ANALYSIS OF TWO        ASSEMBLIES BY SUPERIMPOSING OF AN IMAGE ONTO AN ASSEMBLY                             ABSTRACT             An optical system for forming an image of a refer-ence electronic assembly board or various other articles by presenting the reference assembly onto a fully reflecting surface.  The image is projected onto the first surface of a half-silvered mirror, thereby forming a twice reflected image of the reference assembly.  The assembly for analysis is viewed through the half-silvered mirror, so that a viewer sees the twice reflected image of the reference assembly superimposed onto the assembly for analysis.  By removing the full reflecting surface, the system easily converts to one in which a reference plastic film drawing can be used instead of the reference assembly.
