Abstract: PHF. 83.532                24 ABSTRACT:            A baseband-controlled passband equalizing arrange-ment for correcting carrier-modulated data signals comprises a passband correction circuit having variable elements, demodulation and carrier recovery circuits for converting the corrected modulated signals into baseband data signals, and a control circuit responsive to an estimated error in the base-band signals for controlling the variable elements of the correction circuit.  In known arrangements of this type, the modulated signals are sampled before they are applied to in-phase and quadrature equalizer circuits.  An improvement avoiding any problems associated with sampling and providing in-phase and quadrature equalizer circuits is achieved by providing for a passband correction circuit, which comprises fixed delays and variable parameter elements of multipliers and phase shifters and which produces a time-continuous passband output signal in response to a time-continuous passband input signal.  The values of the variable parameters are not affected by the state of the carrier recovery circuit.

Abstract: ABSTRACT OF THE DISCLOSURE Helical screw rotors for a screw rotor machine having improved asymmetric screw profiles on both male and female rotors, wherein the male rotor lobe leading flank comprises solely first and second circular arcs with the first circular arc subscribed by a first radius which lies on a radial line through the male rotor centre at an offset angle .alpha. to the male rotor lobe centerline in the direction of the trailing flank of the rotor lobe to create a male rotor tip point inherently including a male rotor lobe sealing strip.  Groove trailing flank portions of the female rotor lobes are defined by first and second circular arcs subscribed by first and second radii within addendum and dedendum portions of the female rotor lobes, providing a smooth uninterrupted surface starting below the pitch circle and terminating at or near the outside diameter of the female rotor lobes, with the point of tangency of the first and second radii of the female groove trailing flank portion occurring at a point of zero sliding with the male rotor on the pitch circle.  The female rotor lobes have a main lobe peripheral surface defined by a true circular arc swung from an offset circle centered on the rotor axis at the groove trailing side, inherently producing a female rotor lobe sealing strip and significantly reducing the blow hole area of the screw rotor machine.

Abstract: ABSTRACT OF THE DISCLOSURE        An improved lock cylinder assembly is mountable in a lock case and includes a lock body having an exterior side wall.  The lock cylinder assembly is mountable in the lock case and fixable in a selected position therein by a rotation-blocking side setscrew, and a cylinder-anchoring hidden setscrew.  The lock body is formed to include a cavity for the reception of an interchangeable lock core, at least one elongated channel having a longitudinal axis, the channel including an opening in the exterior side wall for the reception of the side setscrew, and a bore having a longitudinal axis for the reception of a hidden setscrew.  The bore extends between the lock body cavity and the exterior side wall to define an opening in the exterior side wall of the lock body.  Each channel opening and the exterior bore opening are situated in circumferentially spaced-apart relation on the exterior side wall of the lock body.          Orientation of the bore within the lock body causes the longitudinal bore axis to lie in skewed non-intersecting relation to the longitudinal channel axis.  The hidden setscrew is threadedly received in the bore and advanceable therethrough to engage lockingly the lock case and thereby anchor the lock cylinder assembly in its mounted position.

Abstract: ABSTRACT         Disclosed is an integrated semiconductor device comprising a semiconductor body with a first surface having a predetermined orientation with respect to a crystalline structure in the semiconductor body. The semiconductor body has a depression formed into the first surface of the body.  A layer of thin film material covers at least a portion of the first surface.  The device further comprises apparatus comprising the layer of thin film material and further comprising a static electric, thermal-to-electric, or electric-to-thermal element.  The diaphragm apparatus forms a slotted diaphragm substantially covering the depression.  The slotted diaphragm comprises a slot sized and oriented so that, in the fabrication of the device, an anisotropic etch placed on the slot will undercut the diaphragm and form the depression.  The static electric, thermal-to-electric, or electric-to-thermal element is substantially supported by the diaphragm and, therefore, is substantially thermally and physically isolated from the semiconductor body.

Abstract: FLUID PRESSURE SENSOR                 WITH TEMPERATURE INDICATOR            ABSTRACT:      A pressure sensor (33) is provided by a bridge circuit on a semiconductor diaphragm (44), with diaphragm deflection being effective to produce an output voltage proportional to the deflecting force.   A constant current source (62)  is coupled to the energizing terminals of the bridge circuit. By measuring the voltage drop across the semiconductor bridge during operation, an output signal indicative of bridge temperature is obtained.  Accordingly two output signals,  pressure  (32)  and temperature  (35),  are derived from a single bridge sensor (33).  This produces a compact, accurate transducer assembly for use in an automotive control system, providing two control signals from a single sensor structure.
