Title: Improvements in or relating to television receivers
IPC: H04N5/57
Filed: 1938-05-30
Abstract: 515,426. Television. FERRANTI, Ltd., TAYLOR, M. K., and WOOD, H. May 30, 1938, No. 16040. [Class 40 (ii)] Adjustment of the gain of a receiver may give rise to a change in the illumination of the black parts of a picture. To prevent such variations, the whole or part of the potential drop across an amplifier valve which varies the over-all gain, 'is used to control the bias of the cathode-ray tube, either directly or by way of a directcoupled amplifier. In one arrangement, the control grid of the cathode-ray tube 15, Fig. 1, is connected over diode 22 and resistance 27 to a tap on the anode resistance 24 of valve 25 whose gain is variable. If its gain is increased its anode current rises, the potential of the tap falls and increases the negative bias on the cathode-ray tube. In a modification, the potentiometer 19 is connected between resistance 24 and N and the cathode of the cathoderay tube is energized by signals (Fig. 2, not shown). In another modification, the varying potential from 24 is applied to one grid of a valve, and rectified signals to another grid, and the output is applied to the cathode of the tube (Fig. 3, not shown). In a further modification, the resistance 24 is connected via a potentiometer 30, Fig. 4, to the anode of the diode detector 3 and provides a negative potential for the grid bias of the video frequency pentode valve 9 controlling the cathode-ray tube. Specifications 475,728 and 494,502 are referred to.

Title: Feeler gauge for checking geometrical tolerances, or dimensions of work pieces and the like
Inventor: SCHAURTE PAUL
Filed: 1951-07-10
Abstract: 691,837. Linear dimension gauges. PATENTUND VERSUCHS-ANSTALT. July 10, 1951, No. 16352/51. Class 106 (ii). A feeler gauge for checking whether a dimension of a work-piece is within predetermined limits, comprises an electric contact co-operating with the feeler member of the gauge, said contact being arranged to become effective before the actual measuring device of the gauge is actuated. As shown, an axially movable gauging member 2 has a feeler pin 12 movable against spring means 14 in its lower end. When a work-piece 24 begins to pass beneath the feeler pin 12, it displaces the pin 12 upwards against the spring 14. A collar 15, rising with the pin 12, causes two contacts 18, 19 to close. Further upward movement of the pin 12 can cause its upper end 16 to contact the gauging member 2 so that the member 2 and the pin 12 move jointly against the action of further spring means 3. A pivoted arm 5 extends through a hole 6 in the upper end of the gauging member 2, the arm being biased about its pivot 4 by a spring 7 so as to bear against the upper surface of the hole 6. If the dimension of the workpiece 24 is below the predetermined limits, the upper end 16 of the pin 12 fails to contact the member 2 and the arm 5 cannot be moved by its spring 7. For such dimensions a contact 8 on the arm 5 remains in engagement with a contact 9 to complete an electric circuit. For work-pieces having a dimension within the predetermined limits, the upper end of the pin 12 engages the member 2 and raises it sufficiently to allow the arm 5 to float between the contact 9 and a second contact 10, thereby breaking the said circuit. For over-sized work-pieces the contact 8 will engage the contact 10 to complete a second electric circuit. The contacts 18, 19 may be used to actuate a counter 22. For checking the dimensions of concave work-pieces, means such as a hand operated lever may be provided to lift the member 2 whilst the workpiece is being brought into its gauging position. By this means, the contacts 18 and 19 will not be actuated as a result of the positioning of the work-piece. The contacts 18 and 19 may be normally closed and arranged to open only when the work-piece is pushed under the feeler pin 12.

Abstract: 276,777. Pobjoy, D. R. June 30, 1926. Joint-making packing.-Interfitting components having different coefficients of expansion, e.g. a cylinder barrel and head, are locked together by a ring and nut, the ring being out of contact with the inner component and having a conical or taper face fitting on a complementary face on the outer component and having a flat face fitting against a nut screwed on the inner component. The cylinder head 1 is secured gas tight to its barrel 2 which has a lower coefficient of expansion, by screwing the barrel into the head, and tightening the lock nut 3 which forces the conical faced ring 4 against the conical face 6 on the head, the ring being larger than the barrel and out of contact with it. The greater expansion of the head then tends to force the threads on the head and nut 3 into closer contact with the threads on the barrel. The nut is provided with cooling fins.

Filed: 1923-06-26
Abstract: 209,386. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Gilson, R. M.). Jan. 8, 1923, [Convention date]. Alternating current relays.-In a track-circuit signalling system for railways, the track relav used comprises a rotatably mounted disc 12 of aluminium depending in the air-gap between the pole-pieces of a soft-iron electromagnet core 6. The core carries two windings, one winding 8 being connected across the track rails, the other winding 9 being of substantially S-form, the middle portion passing through a slot in the pole-piece, so that current in the winding produces two oppositelydirected magnetic fluxes across the air-gap. Winding 9 receives current of the order of several hundred amperes from the secondary of a special transformer Q which is conveniently housed in the relay casing, Fig. 2. The two windings receive current of the. same frequency but displaced in phase, whereby torque is exerted on disc 12 in one direction or the other according to the instantaneous relative polarity of the currents supplied. Two sets of pivoted arms 15, 17 are provided, each arm carrying two contacts 25, 27, 29, 30. Normally the arms are counterbalanced by weights 31, 32 to hold the middle contacts 27, 29 closed. Pins carried by disc 12 engage slots in the lower ends of links 16, 18 pivoted to the arms 15, 17 so that when disk 12 rotates in either direction from its normal middle position, one set of contacts is operated, the other being unaffected. For example, clockwise rotation of disc 12, Fig. 6, opens contact 27 and closes contact 25, contacts 29, 30 being unaffected. An auxiliary contact 35 is also provided, carried by an arm pivoted at 40 and weighted so that contact 35 tends to open. When disc 12 is in the normal position, contact 35 is held closed by a cam 44 on the disc spindle co-operating with a spring arm 42, but when disc 12 is rotated, cam 44 allows contact 35 to open. When the disc is rotated from one extreme position to the other, momentary closure of contact 35 is avoided by weighted arms 45 forming an inertia time-lag device, the spring 42 yielding to allow passage of the cam. An alternative electromagnetic time-lag device is described in which contact 35 is controlled by a Z-shaped armature pivoted between the poles of an electromagnet so as to make a limited rotation when the magnet is energized, the circuit of the magnet being controlled by a contact operated by a cam similar to cam 44. The inertia of the armature is relied on to prevent momentary closure of contact 35.
