Abstract: Abstract A wall mountable vacuum breaker is disclosed. In one embodiment, there is a escutcheon mountable against the wall over a wall opening, the escutcheon having openings alignable with fluid supply and outlet pipes which terminate near the opening.  There are also a pair of couplings connectable to the respective pipes through the escutcheon, with at least one of the couplings being shaped so as to bear against an outwardly facing surface of the escutcheon when the coupling is connected to the pipe.  This holds the escutcheon  against the wall.  A fastener is provided to connect the main valve body to the respective couplings.  In an especially preferred embodiment, there is provided a decorative shroud that is removably mounted to the valve body so as to enclose the valve body and the fastener.

Abstract: ABSTRACT     This  improved ignition device for a moving grate  type sintering  machine  is an  inexpensive,  compact  combustion device  which can form a strip of flame extending  uniformly and continuously over the width of the strand.   This  igni-tion  device can provide a uniform  ignition intensity,  and the  ignition  conditions of the raw mix can  be controlled optimally by moving the burner and a hood therefor vertical-ly and/or rotatably in accordance with the operational  con-ditions  of the sintering process.  The ignition device thus contributes to prevent the sintered ore from being  unevenly sintered, and to save heating energy.

Abstract: ABSTRACT A data processing system requiring fixed point and floating point computation operations comprises an arithmetic computation unit for providing fixed point arithmetic computations and a floating point computation unit for providing floating point arithmetic computations.  A control store supplies microinstructions to control the operations of both the arithmetic computation unit and the floating point computation unit.  Both units are responsive to several commonly shared control fields of the microinstructions during their respective operations and the floating point computation unit is also respon-sive to at least one additional control field during its operation.  The complexity and cost of the system are reduced over systems which require two complete separate control stores or two completely separate sets of control -fields of a single control store.

Abstract: ABSTRACT OF THE DISCLOSURE           An optical memory disc includes a glass substrate on which a plurality of concentric circular guide grooves or a spiral groove are formed for tracking purposes.  A centering plate is secured to the glass substrate in a manner such that the center of a circular opening formed in the centering plate is exactly coincident with the center of the plurality of concentric circular guide grooves or the spiral groove.  The circular opening formed in the centering plate is utilized to drive the optical memory disc on a turntable.  Since the circular opening is not formed directly in the glass substrate, the center adjustment is easily achieved, and there is no possibility that the glass sub-strate will be damaged when the circular opening is formed.

Abstract: ABSTRACT OF THE DISCLOSURE     A differential pressure transmitter includes a housing, a first chamber within the housing for receiving an input pressure to be sensed and a second chamber for receiving a transmitter adapted to generate an electrical signal representative of the input pressure.  The chambers are separated by a continuously formed, highly resilient diaphragm.  A reaction member embodied as a resilient spring is disposed in the second chamber for sensing a position of the diaphragm resulting from the magnitude of the differential pressure thereacross.  The reaction member has a magnetized structure mounted thereon which coacts with a Hall effect transducer embodied in the transmitter for detecting the relative position of the magnetized structure and therefore of the diaphragm and responsively generating an electrical signal.  The signal may be utilized for positioning actuator controlled dampers within a VAV system duct.

Abstract: IMPROVED CONTROL CIRCUIT FOR A CIRCUIT INTERRUPTER             ABSTRACT OF THE DISCLOSURE   A control circuit is provided for operating a circuit interrupter in response to overcurrent in an alternating-current line in which the circuit interrupter is located. The control circuit includes a transducer for producing output current proportional to the current in the line. A time-current trip signal generator circuit responds to output current representative of moderate overcurrent in the line byproducing a trip signal after the passage of a time period that is inversely related to the overcurrent. An instantaneous trip signal generator circuit produces a trip signal after a predetermined time interval in response to output current between a minimum and a maximum magnitude and increasing at a rate greater than a selectedrate, which conditions indicate the presence of high overcurrent in the line. In the preferred arrangement, the predetermined time interval is measured from the timethat the rate of change of the current exceeds a predetermined rate. Accordingly, when the onset of high overcurrent is detected, the current is interrupted with a minimum possible delay while substantially reducing undesired response to noise and false signals.
