Abstract: AUTOMATIC FREIGHT CAR BRAKE APPARATUS WITH SPRING-APPLIED FLUID-PRESSURE-RELEASED HAND BRAKE                ABSTRACT OF THE DISCLOSURE The usual brake cylinder in a conventional freight car brake apparatus is replaced by a novel cylinder that embodies a pair of pistons and a spring of sufficient strength to effect a hand brake application.  Conventional brake applications and releases are effected accordingly as the usual brake control valve effects the supply of fluid under pressure to and the release thereof from one of the two pistons which are connected to a common piston rod through which force is transmitted to brake applying brake shoes.  The second piston is subject on one side to the force of the spring and on the other side selectively to brake pipe pressure or pressure in a hand brake release reservoir that is charged from the brake pipe to a higher pressure by an air-driven air booster operated by air from the brake pipe.  Thus, the spring is enabled to effect a hand brake application in the absence of fluid under pressure acting on the other side of the second piston.  This application may be released by the supply of fluid under pressure to this other side of the second piston from either the release reservoir or the brake pipe, or some other independent source.

Abstract: ABSTRACT     Two numbers are multiplied together without first changing either of them, if negative, to a positive number, thereby minimizing the time required in the multiplication process.  In the multiplication, depending upon the sign of the multiplier and the sign of a bit in a predetermined bit location of the multiplier as shifted in a shift register, the multiplier and the multiplicand are operated on by either a shift operation  or operated on by a shift and add operation.

Abstract: BUBBLE DOMAIN STORAGE USING IMPROVED TRANSFER SWITCH     Abstract of the Disclosure A magnetic bubble domain storage device comprising a plurality of storage shift registers and at least one major shift register, which serves to provide bubble domains to the storage register and to receive bubble domains from the storage registers.  A novel transfer switch, or gate, is located between each of the storage registers and the major register? which is typically configured in the conventional major/minor loop type of storage organization.  This transfer switch can be made using single level masking or multiple level masking and is characterized in that the locus of bubble domain propagation paths through the switch element generally defines the letter "Y".  These propagation paths are from one arm of the Y to the other arm, from one arm of the Y to the stem or base portion, or the reverse where a bubble domain travels from the stem (base) of the Y to one of the arms of the Y.  In a particular embodiment, the transfer switch is comprised of a Y-shaped magnetic element having a current carrying conductor which crosses the stem portion of the Y-shaped magnetic element.  The particular path travelled by bubble domains through the transfer switch is determined by the presence or absence of a current through the conductor.  Thus, the transfer switch is characterized by at least one magnetic element having a current path crossing the stem portion of the element(s).  The exact shape, width, length, and thickness of the magnetic element, or elements, of the transfer switch can be chosen by the designer in accordance with the propagation structures that are desired.  What is important is that the plurality of paths which the bubbles can follow generally define a Y, where the current path through the transfer switch crosses the path which is along the stem portion of the Y defined by the plurality of propagation paths available.

Abstract: FUEL VAPOR GENERATOR                    Abstract of the Disclosure A fuel vapor generator in the form of a heat conductive member having an elongated U-shaped passageway formed through it.          The member is mounted at the exterior of a carburetor venturi.  A first open inlet end of the passageway extends through the venturi walls and receives atomized fuel from the main fuel nozzle and a portion of the incoming air.  This fuel and air mixture is directed through the passageway where it is heated and the fuel is vaporized.          The fuel and air are drawn from the passageway and returned into the venturi at a location downstream from the main nozzle.  A series of mesh screens extending across the passageway and spaced along its length assist in atomizing the fuel and assuring efficient conduction of heat to the entire mixture of fuel and air within the passageway.

Abstract: VERTICAL TWIN WIRE PAPER MACHINE            Abstract of the Disclosure In a vertical twin-wire paper machine, the initial forming zone is a wedge-shaped zone defined by a small number of deflectors arranged to bring the two wires into pressure engagement with the sheet therebetween and to remove the initial free or rapidly draining water from between the wires as quickly as possible, consistent with good sheet formation with the economical retention of formed components.  The two wires and the sheet therebetween travel through a pressure zone which includes a convexly curved intermittent surface and guide rolls arranged to guide the wires from the wedge zone into wrapping engagement with the intermittent surface under tension causing pressure on the sheet and continued extrusion of liquid through one or both wires.  More than one such intermittent surface may be used, and the final travel of the wires and sheet is to a suction couch roll where the top wire is peeled away at the suction box, leaving the sheet on the upper surface of the bottom wire for pickup and transfer by conventional sheet handling techniques.
