Abstract: ABSTRACT OF THE DISCLOSURE     Rail car brake rigging of the type for use in a two-axle, four-wheel rail car truck is disclosed which em-bodies a double-acting brake cylinder and slack adjustor disposed transversely between the side frames of the car truck and connected to parallel brake beams disposed on op-posite sides of the truck bolster, by a pair of spaced bell crank levers pivotably mounted on one of the beams, one arm of each bell crank lever being pivotably connected to the brake cylinder or its push rod, the other arm of each bell crank lever being pivotably connected to one of a pair of push rods joined to the other beam.  The brake cylinder in-cludes a parking brake actuating lever mounted to the hous-ing thereof for manually, mechanically stroking the brake cylinder in the same manner as during fluid pressure actu-ated brake application, without inducing undesirable beam loadings and yet ensuring uniform application of the brakes at all wheels.  The unique geometry of the invention permits the use of beams having small diameter tubular central sec-tions to which cast brake heads may be easily attached by a circumferential weld.  Spherical joints are disclosed for connecting each push rod at its opposite ends to a bell crank on one beam and to the remaining beam.

Abstract: ROTARY ACTUATOR               (Abstract of the Disclosure) A rotary actuator wherein linear movement of a piston and rack assembly disposed in a unitary housing is converted to precise rotational movement of an operating member mounted to a pinion which operably engages the rack.  The operating member extends outwardly from opposite sides of the housing and is adapted for coupling with either a single or a pair of mechanisms for purposes of selectively controlling operation of the mechanisms.  The actuator includes new means for locating and supporting the rack, for locating and sealing a pinion as-sembly in the housing, for precisely controlling rotational movement of the operating member, and for precisely and posi-tively locating mechanism mounting brackets to the housing. The actuator may be either single or double acting.

Abstract: ABSTRACT OF THE DISCLOSURE           In conventional blood pressure measuring apparatus, the simultaneous measurement of a pulse rate and a blood pressure is difficult without the use of complicated attachment devices. In this invention, a pulse rate measuring circuit is provided along with a blood pressure measurement apparatus for a simultan-eous measurement of both pulse rate and blood pressure.  Both measurements are derived from at least one microphone signal contained in cuff-device.  The pulse rate measuring circuit is designed to commence counting of the number of pulses after at least two Korotkoff's sounds have been detected and continues counting until a predetermined number is reached while the time period required for counting the predetermined number of pulses is measured.  The pulse rate is determined by dividing the pre-determined number by the measured time period.

Abstract: ABSTRACT                 In structuring thin layers by means of cathode sputtering. two effects result in redeposition of already sputtered maternal: 1. Readsorption on the layer to be structured as a result of impact of already sputtered material on inclined edges (For example of the etching mask) and 2. Back-diffusion on the layer to be structured as a result of a reduction of the average free path length of sputtered material at higher working gas pressure.                As a result of this, etched structures show either non-etched parts (strong readsorption of sputtered material) or the etched structure shows, strong grooves at the edges of the etching mask (strong back-diffusion of sputtered material).  With a variation of the working gas pressure an adjustability of the average free path length of the atoms of the sputtered material and hence the adjustability of the quantity of material redeposited on the basis of back-diffusion is obtained.  The working gas pressure can hence be adjusted so that the etching tome to remove the readsorbed material and the material deposited again by back-diffusion is locally constant and equal etching rates are obtained for all areas of the structure to be etched.

Abstract: FURNACE PRESSURE CONTROL                         ABSTRACT           There has been provided a control for regulating the pressure excursions in a furnace having forced draft and in-duced draft fans.  A pressure detector responsive to pressure in the furnace delivers an output indicative thereof.         Circuit means, responsive to the pressure detector means and a set point input, delivers a correction signal output.  Fan control means coupled to the induced draft fan is responsive to a demand input signal corresponding to a desired flow rate through the furnace and is likewise responsive to the correction signal for delivering a fan control signal for regulating said induced draft fan in accordance with variations in the flow rate and pressure excursions in the furnace. An override circuit is responsive to the pressure detector and an override set point input to produce an override output for controlling the induced draft fan at a rate substantially higher than that of the correction signal.  There is also provided a transfer and memory circuit responsive to com-bustion air flow to the furnace and a furnace trip condition such that the circuit produces a signal to modify said fan control signal in accordance with the actual air flow to the furnace and in anticipation of an inevitable furnace pressure excursion caused by said furnace trip.

Abstract: ABSTRACT OF THE DISCLOSURE The invention provides means and method for adaptively filtering input signals which are made up of pulse signals and noise, and where the pulse signals occur at unknown times and have unknown durations.  Received input signals are filtered by a signal filtering means having a controllable filter characteristic and also delivered to a signal analyzing means.  The signal analyzing means provides signals to the filter means for controlling the filter characteristic of the filtering means.  This results in the delivery of output signals by the filtering means which correspond to the pulse signals of the input signals while minimizing noise signals. The means and method uses orthogonal transformations of the input signals for processing the input signals and adaptively filtering the orthogonal signal components for providing pulse signals present in the input signal with reduction in the noise level.

Abstract: GAS EVOLVING CLAMP FOR CURRENT LIMITING FUSE                 ABSTRACT OF THE DISCLOSURE         A current limiting fuse of the general purpose type utilizes a mandrel which has a plurality of longitu-dinally oriented and radially spaced ceramic rods around which is wound a fuse element.  Gas evolving clamps are disposed along the mandrel to hold the fuse element against the rods of the mandrel.  This arrangement tends to maintain the spacing of any given portion of the wound fuse element relative to the other portions thereof.  In addition, the gas evolving material evolves arc quenching gas in localized regions between the clamps and the rods during a fusing operation.  The pressure of the gas as it is expelled from the localized regions tends to prevent the formation of fulgurites in the regions after the fusing operation has been completed.  A fulgurite if formed would enhance the opportunity for a restrike of the arc which is undesirable.
