Title: Improvements in indicating or counting mechanism for metering apparatus
IPC: G01F15/07
Filed: 1932-04-08
Abstract: 395,468. Counting-apparatus. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Brodie Co., R. N.; 61st Street, Oakland, California, U.S.A.) April 8, 1932, No. 10169. [Class 106 (i).] In a counting and indicating mechanism for liquid-delivering apparatus, the higher denomination of values is indicated by a pointer driven from the lower denomination pointer through an intermediate gear prevented from rotating but capable of a gyratory motion. In the arrangement shown, the meter spindle 16 is geared through pinions 19, 20 with the spindle 21 carrying the gallons pointer 14 and connected by a tubular shaft 24 and universal joints with a similar spindle and pointer for indicating on a duplicate dial. The pinion 20 is spring-urged against a disc 25 fixed to the spindle to permit zeroizing by reversal of the latter. Loose on the spindle 21 is a gear wheel 29 carrying the 20-gallon hand 15 and enclosing a disc 31 the elongated hub 32 of which is eccentrically mounted on the spindle. On this hub is a non-rotating 40-toothed spur wheel 33 adapted by its gyration to drive the wheel 29 through four pins 34 projecting therefrom. The wheel 33 is held against rotation by a disc'35 having an arm 36 engaging between lugs on the casing and frictionally pressed against the wheel by a spring backed by a cam 39 fixed to the hub 32. At each gallon this cam releases the hammer of a bell 42. The disc 31 is notched to co-operate with a pawl on the gear wheel 29 so that when the spindle 21 is rotated backwardly for zeroizing the disc will pick up the pawl and carry the wheel 29 and therefore also the hand 15 back to zero position as determined by a stop pawl on the casing engaging a notch in the wheel.

Abstract: 371,152. Poppet valves. CRAWFORD, F. C., 2196, Clarkwood Road, Cleveland, Ohio, U.S.A. April 7, 1931, No. 10278. [Class 135.] Cooling; making. -To provide for the cooling of poppet valves, the stem 2 of the blank is drilled out to receive a core 6 of copper or other highly-conductive metal, which is welded in position in a non-oxidizing atmosphere. The welding may be effected in a furnace in which an atmosphere of hydrogen is maintained, a small amount of flux 7 being applied at the end of the core, and the temperature being brought slightly higher than the melting point of the core. The core is then drilled hollow, and the outer enlarged end 4 of the blank is swaged down so as to close the end of the valve stem. A wearing-piece is then welded on to the stem end, and the valve head worked into shape.

Title: Television channel indicator
IPC: H04N5/445
Filed: 1973-03-02
Abstract: 1388966 Television channel indicator; cathode ray tube displays SHARP KK 2 March 1973 [3 March 1972] 10331/73 Heading H3Q and H4T A television channel indicator has a character generator 20 responsive to selection of a television channel to generate a character display on a television screen indicative of the channel selected. A switch 47, Fig. 6, is selected with moving the channel selector 3, Fig. 1, so as to programme a encoder 48 such as a diode matrix (Fig. 7, not shown), of a character selection circuit 19 to provide a coded signal output, from a decoder 49 such as a diode matrix, corresponding to the selected channel. The output from the character selection circuit 19 is supplied to a character generator 20 which feeds its output to a signal composition/substitution circuit 17 which enables the channel character indication, VHF channel number or UHF channel U and channel number (Fig. 5, not shown), to be displayed on the tube 7 with or without the video signal from a video amplifier 6 for a time determined by an indicator period setting circuit 18. The character generator 20 includes counters 50 and 53 operated by the vertical and horizontal pulses and from a pulse oscillator 52 having a high frequency compared to the horizontal scanning frequency, vertical and horizontal unit signal generators 51 and 54 formed by gates, segment character and character output signal generators 55, 56 and 57 formed of gates and an AND gate 58. The indicator period setting circuit 18 may be a one shot transistor multivibrator (Fig. 2, not shown) or a transistor Schmitt circuit (Fig. 3, not shown), with the delay period provided by discharge of a capacitor (43). In a modification to Fig. 6 (Fig. 10, not shown), when no synchronizing signals are detected the selection of the channel character signal is inhibited from the character generator 20 so as to prevent indication of that channel on the tube. The channel characters may be made to slant (Fig. 12, not shown), by including integration circuits 64, 65 and a comparison circuit 66 which may be transistor circuit (Fig. 14, not shown), used to control the pulse oscillator 52. With five horizontal scanning lines occurring during one vertical scanning period the integration circuit 64 provides five sawtooth outputs (Fig. 13, not shown), to one sawtooth output from the integration circuit 65. The comparator transistor 66 compares these sawtooth outputs and conducts for each of the horizontal pulses to provide five successively shorter duration output pulses during one vertical scanning period. The pulse oscillator 52, which includes NAND gates 84, 85 is energized by the output pulses from the comparator so as to enable formation of the slanting channel characters..

Abstract: 1469355 Fluid-pressure servomotor systems ROBERT BOSCH GmbH 18 March 1975 [20 March 1974] 11318/75 Heading G3P The stroke ring 13 of a variable displacement pump 10 is adjusted by pistons 16, 17 one of which is controlled by a spring-loaded valve actuated by a pressure signal from one of a number of pressure-responsive valves 62, 63, 64 and by a flow signal produced by the pressure drop across one or more flow restrictors 39, 40, 41. Electromagnetically-actuated valves 68, 69 and 42, 43, 44, which may be computer-operated, determine which pilot valves and flow restrictors are to be operative. The throttles supply a hydraulic motor 49 and may be made adjustable to provide stepless speed control. The motor is connected through a non-return valve 52 to a return line 51 which also receives the return flow from cylinders 54, 55, 56 supplied by the pump 10 through valves 57, 58 and 59. The cylinder 56 can also be supplied through a valve 83 by a constant delivery pump 81 provided with a pressure-limiting valve 85. A further valve (88), Fig. 2 (not shown) may be incorporated in the block 61 of pressure relief valves to permit the pump 10 to be unloaded or to be controlled by a further pressure relief valve (91). The valves 68, 69 may be replaced by a series arrangement of twoway valves (98, 99) Fig. 3 (not shown) which the valves controlling the flow restrictors may be piloted operated if large flows are to be controlled. Both the pressure and flow control systems may be incorporated in a single block and the pressure reponsive valves may be continuously adjusted by a potentiometer (139) Fig. 6 (not shown) in a servosystem.

Abstract: 654,436. Detectors ; radio receiving systems. COMPAGNIE DES FREINS ET SIGNAUX WESTINGHOUSE. April 26,1948, No. 11345. Convention date, May 23, 1947. [Class 40 (v)] A push-pull rectifier is formed by simultaneously coating with equal thickness in one operation opposite faces of a metal base-plate 1 with semi-conductor layers 3a, 3b, and simultaneously coating each of those layers with a counter or contact electrode, and by a pair of connecting electrodes 4a, 4b each bearing at only one point on the counter-electrodes. The connecting electrodes may be formed by introducing molten or fusing comminuted metal in conically recessed insulating members 6a, 6b overlying the base-plate and counterelectrodes except at the tip of the conical recesses. The base-plate by extending beyond the periphery of the insulating members acts as a capacity screen between the connecting electrodes. The layers 3a, 3b may be semiconductor or copper layers formed in recesses of the base-plate and having crystalline needles, e.g. of iron, platinum or gold, produced thereon and finally the counter-electrodes formed by precipitation of vaporized conducting material or by electrolytic deposition. In Fig. 4 a detector as in Fig. 1 is located in a cavity resonator with plates 11a, 11b connected to the electrodes 4a, 4b capacitively coupled with opposite flattened walls 10a, 10b of the reson. ator to form a mixing arrangement. The aerial coupling 9 is arranged as shown to drive the mixer in push-pull and the oscillator 13 and coaxial line 14 to drive it in parallel. The intermediate frequency is taken off in pushpull by coaxial lines 12a, 12b.
