Abstract: ABSTRACT OF THE DISCLOSURE A power circuit includes a DC-AC inverter circuit having a boosting transformer; an intermediate terminal connected to the boosting transformer, through which a DC input voltage is supplied to the boosting transformer; and a control circuit for controlling operation of the inverter circuit.  In the power circuit, first and second conditions are alternatively selected with the control circuit.  In the first condition, the inverting operation is effected with the inverter circuit, and in the second condition, the DC input voltage is led out through the boosting transformer without the inverting operation of the inverter circuit.          According to the above-described power circuit, although two different DC input voltages are alternatively supplied to the power circuit, a constant DC output voltage can be obtained from the latter.  Further, even when a constant DC input voltage is supplied to the power circuit, two Different DC output voltages can be obtained from the latter.

Abstract: ABSTRACT OF THE DISCLOSURE   This invention generally relates to electrical connectors and more particularly to electrical connectors for receiving a male connector or printed circuit board.  Specifically, this invention relates to an improved electrical contact structure within an electrical connector for printed circuit boards whereby the electrical contact maintains electrical continuity therethrough independent of the circuit board until the circuit board achieves electrical contact therewith.  It is sometimes highly desirable or even necessary to maintain an electrical continuity or closed circuit between the paired contact members without the presence of a circuit board therebetween.  Previous designs to achieve the above generally included bifurcated electrical contact members whereby a continuous closed circuit is constantly maintained directly between the contact members with or without the presence of a circuit board there-between.  One problem with such a design is that short circuiting may occur when the circuit board is in place between the contact members due to the continuous direct electrical contact between the contact members simultaneous with the continuous contact between the contact members and the circuit board.  The present invention overcomes the above problems by providing, an electrical connector having electrical contacts which maintain electrical continuity therethrough independent of the printed circuit board until the circuit board is in electrical engagement therewith at which point the direct circuit between the contact members ceases.

Abstract: Abstract of the Disclosure A system is provided for developing a gating signal when a radio-frequency signal receiver is tuned to the center-frequency of a selected radio-frequency signal.  The system comprises circuit means for tuning the receiver to a plurality of frequencies within a range of frequencies which includes the selected signal and for producing an intermediate frequency signal corresponding to the frequency to which the receiver is tuned.  A frequency discriminator is coupled to the circuit means and is tuned to a predetermined frequency, with the fre-quency signal for developing an output signal having a DC component which varies systematically in accordance with the deviation of the intermediate frequency signal from said pre-determined frequency.  A detector is coupled to the frequency discriminator and is responsive to the DC signal component for developing a gating signal, with the gating signal having a first value when the DC component has a value between preselec-ted upper and lower threshold values and with the gating signal having a second value when the DC component has a value which is not between the upper and lower threshold values.  A gating circuit is coupled between the circuit means and an electromechan-ical transducer and is responsive to the gating signal for enabling reproduction of audio signals by the transducer only when the gating signal has the first value.

Abstract: ABSTRACT OF THE DISCLOSURE             CONNECTION MECHANISM FOR AUTOMATIC SLACK ADJUSTER   An automatic slack adjuster for a vehicle braking system includes a yoke assembly which is pivotally mounted on the adjuster body and which is adapted to be connected to a push rod actuated by a fluid pressure actuator.  The yoke assembly includes a recess having an entrance which is adapted to receive the end of the push rod.  An adapter member is threaded on the end of the push rod received in the recess, and a U-shaped connector penetrates the body of the yoke to engage a circumferentially extending groove on the adapter, to thereby define a nonthrust transmitting connection between the yoke and the push rod.  The yoke assembly defines a thrust receiving surface which circumscribes the entrance to the recess, and a thrust washer slidable on the push rod is held at a thrust transmitting engagement with the thrust receiving surface by a nut which is threaded on the end of the push rod.  Consequently, braking thrust is exerted on the yoke assembly through the push rod, the thrust washer, and the thrust receiving surface.

Abstract: A B S T R A C T              The specification describes a new digital compandor which possesses a nonlinear companding characteristic and which is capable of making the conversion between linear and nonlinear code signals without the use of large capacity read-only memories (ROM).  The new compandor receives a linear code signal consisting of polarity bits representative of the polar-ity of a sample value of an original analog signal and a plurality of absolute value bits representative of the absolute value of the sample via a plurality of input terminals.  A first ROM is addressed by a first bit group.  The ROM memorizes a segment bit decision rule for use in determining segment bits based on this first bit group.  A second ROM is addressed by a second bit group which includes some bits in common from the first bit group. The second ROM memorizes a first mantissa bit decision rule for use in determining mantissa bits based on the second bit group.  A third ROM is addressed by the first bit group and memorizes a second mantissa bit decision rule for deter-mining mantissa bits based on the first bit group.  Depending upon the value of the most significant bit among the segment bits supplied by the first ROM, an additional chip selector selects the second or third ROM means.  The original linear code signal is thereby converted into a nonlinear code signal which consists of a polarity bit, a plurality of segment bits that represent the segment to which the sample value of the original analog signal belongs and mantissa bits that indicate the position of the sample bit in the segment.

Abstract: ABSTRACT            Improvements in or relating to Breathable Gas Delivery Regulators The invention provides a breathable gas regulator of the demand type for use with a low supply pressure (10 p.s. i. or less) gas source.     The regulator requires no greater demand effort on the part of a user than is required with present-day regulators of the same type which operate with much higher pressure (70 p.s.i. and above) gas sources, and it requires ducts, diaphragms and valves of no greater size than are required by present-day regulators.  This is achieved by inclusion of a servo valve that is actuated by a fluidic amplifier arrangement responsive to the user's breathing pressure.     In an embodiment of the invention particularly suited for use by an aviator, the regulator includes a pneumatically operated mixing valve arrangement for automatically varying, according to altitude, the proportions of, say, oxygen and air supplied to the demand valve of the regulator, and the mixing valve arrangement includes a fluidic gas concentration sensor.

Improved strength, stability, and wear resistance of the safety roller support member (32) bearing surface(s) are provided in various arrangements (Figures 1, 5 and 6), generally by a relative increase in the area of lateral and skew movement-resisting  bearing surfaces 30 and 34.

New forms of circum-ferentially inextensible but laterally elastic rings (40, 42; 60;70) are proposed (Figures 1, 2 and 3) for bearing member (28) location by substantial lateral compression thereof (without  possible unwanted radially outward loss of location as in the prior art).
