Abstract: Abstract A selective amplifier whose gain characteristic is rendered approximately uniform over the entire frequency band to be amplified with no degradationin the S/N ratio.          The amplifier consists of a band-pass filter and an amplify-ing element, in which a resistor for eliminating the ripples in the transmission characteristic of the filter is constituted with a feed back resistor for the amplifying element, the coil for the parallel resonance circuit in the filter is constituted as an auto-transformer and the capacitor in the serial resonance circuit of said filter is formed with the capacitance of a capacitive antenna respectively to thereby improve the S/N ratio.  The amplifier is suitable to be used at the  top of the high frequency stages in a radio receiver.

Abstract: ABSTRACT.            Lead salt electric storage battery. In a one-cell or multi-cell lead salt electric storage battery with electrodes of first order, the anode of the cell or each cell has an active anode body (4) consisting of a textile material graphitized at a temperature of at least 2500°C. This active anode body is connected with an electrolyte-impervious, electrically conductive cell closure (1) consisting of moulded artificial resin with moulded-in, uniformly distribu-ted short-cut graphite fibers likewise graphitized at a temperature of at least 2500°C. The connection between the active anode body and the cell closure is established either by gluing with an artificial resin glue (5) with mixed-in short-cut graphite fibers, likewise graphitized at a temperature of at least 2500°C, or by embedding fibers at the surface of the active anode body in the artificial resin of the cell closure (1 ) by temporary softening of the surface of said artificial resin by heat or by the application of a volatile solvent. The electrolyte consists of lead silicofluoride (PbSiF6) and/or lead methane sulfonate (Pb(CH3SO3)2) dissolved in water. The cell or each cell of the battery may be perma-nently hermetically closed because no gas is developed within the battery at any time. ( Fig . 1 is considered suitable for accompanying the abstract.)

Abstract: ABSTRACT         A hot-electron or hot-hole transistor includes a base region through which current flow is by hot majority charge carriers.  The emitter-base barrier-forming means comprises a barrier region having a sufficiently large thickness and impurity concentration of the opposite conductivity type that said barrier region is at least over part of its thickness undepleted by the depletion layer or layers present at the emitter-base barrier at zero bias.  The application of a bias voltage (VBE) between the base and emitter of the transistor is neces-sary to establish a supply of said hot majority carriers having energies above the base-collector barrier, and this improves the collection efficiency of the transistor. In one form the emitter-base barrier-forming means also comprises a Schottky contact.  In another form the emitter comprises an ohmic contact.  The supply of said hot majority carriers may be established by avalanche or zener breakdown of said barrier region or by punch-through of the depletion layer(s).  A low emitter capacitance can be obtained by including between the emitter contact and said barrier region a lower-doped zone of either conductivity type so as to spread further the depletion layer(s) at the emitter-base barrier.  The base-collector barrier can be formed by a fully depleted barrier region.  The transistor structor can be formed using ion-implatation or/and molecular beam epitaxy.

Abstract: ABSTRACT OF THE DISCLOSURE     A vehicle hydraulic system is disclosed of the type including a steering control valve (29), a brake system (31), and an auxiliary load circuit (65).  Fluid flow to these load circuits is controlled by a flow control valve assembly (11) including a priority spool valve (85) which controls the flow of fluid from the inlet port (13) to the priority fluid chamber (75).  Fluid flows from the priority fluid chamber to the steering control valve and the brake load system, in parallel, and at equal levels of priority.  A shuttle valve assembly (83) receives a steering load signal by means of a load signal line (44) and a brake load signal from the load signal chamber (111), and transmits the higher of the two load signals into the load signal chamber (93) which biases the priority spool valve toward a position to permit a greater flow of fluid into the priority fluid chamber.  Therefore, the control valve assembly disclosed herein requires only a single pump to provide sufficient fluid to satisfy the simultaneous demand for fluid by both the steering system and brake system.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for determining volumetric fluid flow rate in an arbitrarily shaped fluid conveyance are disclosed.  A plurality of functions, fj(p,mk) (where p is a position in the conveyance and mk depends upon the Reynolds number of the fluid flow), each function being approximately representative of the fluid flow velocity across the conveyance, are linearly combined to approximate the velocity, P(p), of the fluid flow at any point in a plane normal to fluid flow. The scalar constants Aj, k, of the linear combination      , are estimated by solving a system of linear equations,     in which acoustical measurements along the paths yi through the conveyance provide an estimate, ?meas(i), of the actual average velocity ?i at paths yi.  The average fluid velocity and hence volumetric flow across the conveyance can then be determined by taking an area integral of the linear combination    .

Abstract: INCREMENTAL BENDING METHOD AND APPARATUS               Abstract of the Disclosure Small gauge metal tubing is bent into required configuration by a repeated bend-shift-bend method in which the tubing is advanced intermittently through a bend head which operates to put an incremental bend portion of controlled angular extent into the tubing. The method determines the final configuration of the tubing as a function (i) of the number and/or angular extent of the incremental bend portions, and (ii) of the extent of translation of the tubing between successive incremental bend portions.   The method also envisages rotation of the tubing for determining the plane of the incremental bends.   A bending machine for performing the method comprises a powered carriage (3) movable within a channel track (38) under control of a motor (13) and carrying a lazy-tongs type clamping arrangement (8) which is rotatable by a motor (44) for axially rotating a clamped tube (1) being bent.   The carriage (3) moves the clamped tubing intermittently and by controlled amounts through a bending head (4) which comprises a hydraulically operated die and former arrangement wherein the die and former are relatively movable to put an incremental bend portion into that part of the tubing which is engaged with the bending head.   The bending, translating and rotating movements in the machine can be computer controlled.

Abstract: ABSTRACT OF THE DISCLOSURE          A system for transmitting an audio signal in pulse width modulated form on a video signal is disclosed.          The audio signal is modulated by varying the time occurance of at least one edge of a pulse as a function of the voltage level of said audio signal at a selected time.          The pulse is then added to the video signal during each horizontal blanking interval.  Upon receipt of the transmitted signal, the video signal is processed to reform said edge varying pulse.  An output pulse is then generated for each varying edge of said pulse, whose pulse width is a function of the time of occurance of said edge with respect to a stable reference edge.  This output pulse is then used to generate a voltage signal whose level is determined by the pulse width of said output pulse.  The successively generated voltage levels comprise the reformed audio signal.
