Title: Improvements in or relating to radio receivers
IPC: H03G3/26
Filed: 1933-10-11
Abstract: 427,629. Valve circuits for wireless reception. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Barton, L. E. ; 228, Burrwood Avenue, Collingswood, New Jersey, U.S.A.) Oct. 11, 1933, No. 28072. Convention date, Nov. 3, 1932. [Class 40 (v)] In a system in which automatic gain control is applied to an amplifier the signal is rectified and the D.C. component of the voltage produced is amplified and applied to effect the gain control through a second rectifier, the first rectifier being also the signal demodulator and biassed to effect inter-channel noise suppression while the second rectifier is biassed to delay the application of the control potential until the signal reaches a predetermined amplitude. As shown the rectifiers and gain control amplifier are constituted by a double-diode triode valve 11 the signals being applied to the diode anode 16 which in the absence of signals is negatively biassed due to the opposition of the voltages produced by the cathode resistance 20 and the potentiometer 22 with a variable tapping 21. The potentiometer 22 is shunted across a portion of the main potential divider R1 supplying anode &c. potentials to the receiver and the loud-speaker field winding L1 feeding this potential divider the junction therebetween being earthed. The D.C. and signal potentials developed across the load resistance 24 of the diode 16 are fed to the grid of valve 11 through a resistance 23, the signal output of the triode being developed across the anode resistance 25 and fed to subsequent amplifiers 13, 15, 17 through a condenser 36 while the D.C. gain control potentials are developed across the cathode resistance 20 and fed to the preceding amplifiers 1, 7, 9 through the diode 18 and resistances 27, 28, 29 which are connected in series between its anode and earth. The delay voltage on the diode 18 is due to the opposition of the voltages produced by the resistance 20 and the loud-speaker L1 in its circuit. In a second embodiment Fig. 2, (not shown), the valve 11 is replaced by a diode-tetrode, the tetrode portion of which has two coplanar grids one of which is used as a rectifier anode. In a further embodiment Fig. 3, (not shown), the potentiometer controlling the delay bias potentials is arranged to operate a switch to remove all bias on the signal detector in its position of maximum sensitivity. Specifications 395,277, 410,619, and 427,650 are referred to. The Specification as open to inspection under Sect. 91 comprises also a circuit in which manual volume control is applied between the detector and the first amplifying triode. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 407,317.

Abstract: 964,346. Detecting flaws in metal. TIMKEN ROLLER BEARING CO. Aug. 3,1961 [Nov. 2, 1960], No. 28211/61. Heading G1N. [Also in Division B3] Defects in a wire 24, Fig. 1, being drawn through a die 28 and rewound on a drum 26 are sensed by a head 30 which produces an electrical signal and thus operates a cutter 34 to mark in the manner shown in Fig. 3 a defective length of wire, the cut away defect marking portion being made to overlap the defective portion at both ends by positioning the cutter to commence cutting in front of the detected defect and by prolonging the signal by a hold circuit of suitable time constant. The cutter is controlled by a solenoid, which is responsive to the defect signal, actuating a hydraulic valve controlling the flow of air or fluid to the sides of a piston the rod of which is connected to the pivoted cutter. The wire which is to be used in the manufacture of tapered roller bearings is pushed by pressure loaded rollers 64, Fig. 5, into the feed portion of a cold heading machine 56 and through an aperture 74 in a shear blade 76 to a stop 84, the blade then being moved laterally, to shear a slug and carry it into alignment with a taper die 88. A punch 92, Fig. 8, and a headed pin 78 pushes the slug into a die 94 where a part of the desired taper is imparted, and as the ram recedes the pin 78 is withdrawn clear of the cut-off plane and transferred to a second ramming position where a head die 96 is in alignment with the tapered socket 94. The tapering of the slug is completed and the end is grooved as at 97, Fig. 13. A knock out pin 98 ejects the roller into a shoot 102 where it is guided by a deflector 142 into bins 140 or 138 according to whether or not the wire from which it was made was marked as defective. Control of the deflector is effected by the drop of pressure in an air line 122, Fig. 7, which is coupled via passages 118, 116 to an orifice 114 in a ring unit 104 through which the wire passes, the presence of a cut away mark allowing the air to escape to atmosphere through orifices 132, 134. The air supply line includes an air filter unit, a line pressure safety switch which shuts down the machine if the pressure falls below a predetermined minimum, a pressure reducing valve, an adjustable restriction valve, an air pressure gauge and a reject control switch. Suitable pressures are exemplified and an electrical control circuit which includes a mechanically operated counter provided to maintain the reject solenoid in the reject position until a predetermined number of rollers, made after each defect, have been rejected, is described with reference to Fig. 15 (not shown). The circuit also includes a shut-down switch which is operated by the passage of the end of the wire. Alarm signal lights are included. Specification 964,347 is referred to.

Abstract: 505,893. Thermally-actuated valves. SAFETY GAS DEVICES,. Ltd., RABINOWICZ, M., and KESTENBAUM, I. Oct. 16, 1937, No. 28234. [Class 135] A safety cut-off device for a gas burner comprises a valve plug A, Fig. 1, having a main gas passage B and a passage C 'for a pilot burner which are both adapted to be shut off in the event of the pilot burner being extinguished. The means for effecting. this closure comprises a spring-loaded disc H having a lostmotion connection with the plug A so that the main gas supply can be adjusted whilst the disc H is held in its loaded position by a thermostatic catch engaging in a notch J. The pilot passage C communicates with peripheral grooves D so that the pilot burner is not affected by this adjustment. The thermostatic device is heated by the pilot jet, but on the latter being extinguished the catch is released so that the disc H is actuated to rotate the plug A to a position in which both main and pilot passages are closed. In Fig. 2, two concentric plug members are used, the inner one f being operated through a lost-motion device from the handle C of the outer hollow member b and being retained by a catch q controlled by a thermal element r heated by a pilot jot p. The outer member h can then be adjusted to control the main gas passage d, d<1> without affecting the pilot supply through passages h, i and j. On the pilot jet p being extinguished the inner plug f is rotated by a loading spring w to a closed position. The pilot burner p in this arrangement is pivoted at t and adapted to be swung away from the thermal coil r when the thermal catch has engaged so that it does not play directly onto the coil continuously.

Abstract: 1356509 Educational appliances WESTING- HOUSE ELECTRIC CORP 16 June 1972 [30 July 1971] 28245/72 Heading G5G An instructional system includes a multichannel recording/reproducing medium having stored thereon recorded material in the form of instructions, lectures, questions, remedial material &c. together with channel transfer codes, and listener operated response switches for entering response following a question, these switches being actuated at a branching point in the learning programme. As shown, a four track magnetic tape can move in reverse or forward directions relative to a reading head, and is stopped at the completion of a question, following a recorded lecture, at a branching point BP. The tape remains stationary until a response switch A, B, C, D, E or R (repeat) is manually operated, a particular channel and direction from the branching point being assigned to each switch. Thus, switch A selects channel 2 in the reverse direction while switch B selects channel 4 in the reverse direction, and so on as illustrated. Each response therefore results in the reproduction of supplemental or remedial material peculiar to that response. The recorded code signals following segments of material reproduced following a response serve as transfer signals to ensure reproduction of all the material on the various channels and in the appropriate direction necessary to complete the instruction appropriate to the response, this completion re-establishing the system at the branching point. Particular lesson plans recorded about a branching point are described with reference to Figs. 7, 8 and 9 (not shown), and a block diagram of a suitable circuit arrangement for effecting the required operation is described with reference to Fig. 2 (not shown). The recording medium may be a film, having up to twelve visual-audio channel pairs, instead of a magnetic tape.
