Title: Conveyors
IPC: B65G17/20
Filed: 1977-06-09
Abstract: 1526167 Endless conveyers for cylindrical articles AMERICAN CHAIN & CABLE CO Inc 9 June 1977 [9 June 1976] 24054/77 Heading B8A Cylindrical articles A (Fig. 3) are retained between pairs of grippers 14a, 14b, by the action of the article A being pushed upwardly to engage portions 38, 39 of the grippers. This deflects a spring 35 over-centre of the pivot of the arms 14a thereby causing the arms 14a, 14b to move together, to grip the article A and be retained by the action of the spring 35 in its new overcentre position. In its previous position the spring 35 holds the arms 14a, 14b in their open position. The article A receives its upward push by the action of a transfer arm 20 (Fig. 1). Articles are loaded on to the arm 20 when in its lower position (dot-dash lines) by a conveyer 23. A control circuit (Fig. 8, not shown) insures that articles are fed by the conveyer to the arm 20, and by the arm 20 to the grippers 14a, 14b, only when there are suitable vacancies on the arm or grippers, as the case may be. The control circuit includes photo electric gates PER 1, PER 2, and limit switches LS1, LS2 and LS3. A similar apparatus (except that the arm 20 is replaced by a transfer shoot) is provided for handling the articles A at a discharge station (Figs. 6, 7, and 9, not shown). Opening of the grippers 14a, 14b at the discharge station is effected by a solenoid operated cam member (47) which engages a pin 40 (Fig. 4), and forces this down against a spring 42 from a gripperlocking position.

Title: Improvements in or relating to electric full-wave rectifiers
IPC: H03K7/08
Filed: 1944-12-01
Abstract: 586,098. Pulse modulation. STANDARD TELEPHONES & CABLES, Ltd. Dec. 1, 1944, No. 24103. Convention date, Dec. 6, 1943. [Class 40 (v)] In a full-wave rectifier circuit adapted to produce time-modulated pulses, an A.C. voltage wave is fed to the grid of a valve, out-of-phase versions thereof being derived from the anode and cathode circuits and applied through individual cathode follower stages to two rectifiers whose outputs are combined. This produces a wave with spaced peaks, the timing of which is modulated by the amplitude modulation, in push-pull, of the rectifier inputs. In one embodiment, Fig. 1, the output of a sine-wave oscillator 14a is fed to triode 14b which produces the rectangular waveform 20 by saturating on positive half-cycles and cut-off on the negative. The rectangular waveform becomes triangular, 12, in the integrating network R3, R4, C1, the output from which is fed to the grid of valve 32. Out-of-phase waves from the anode and cathode circuits of this valve are fed through cathode-follower stages 41, 42 and the secondaries 72, 73 of a modulation transformer 70 to diode rectifiers 37, 38 having a common load resistance. Referring to Fig. 2, the rectification " axis " for the wave 12 is set at a predetermined place such as 48 by the grid bias potentiometer 46, Fig. 1, and modulation applied from the primary of transformer 70 shifts this axis between the limits 76a, 77a for example. The rectified output, in the absence of modulation, is shown as curve 50 and this is modulated between the limiting forms 76, 77. The clipper and shaper circuits 60, Fig. 1, clip the rectifier output at level 62 to select the peaks 51, 52 ; 53, 54 ; 55, 56 and convert them into pairs of narrow pulses 51a, 52a, &c. modulated between the limits 78, 79 towards and away from each other. It is stated that the wave applied to valve 33 may be sinusoidal if the modulating swing is limited to the approximately linear portion of the wave near the axis. In a modification, Fig. 3 (not shown), the transformer 70 is connected in the grid circuits of valves 41, 42. Alternatively, the modulation may be applied to separate grids of mixer valves substituted for valves 41, 42.

Title: Throttle control lever locking mechanism for aircraft
IPC: G05G5/08
Filed: 1947-09-03
Abstract: 631,290. Controlling aircraft. GENERAL AIRCRAFT, Ltd., PROWER, C. W., and CHILDS, A. F. Sept. 3, 1947, No. 24341. [Class 4] A multi-engined aircraft fitted with control surface locks is provided with a throttle control lever locking mechanism which prevents simultaneous movement of all throttle levers for take off of the aircraft with the flying controls locked but permits of some of the engines being operated for taxying purposes. The throttle control locking device comprises a sliding plate 4 fitted with a hand grip and sliding in guides 5 mounted on the control quadrant 1. Two levers 6 are pivoted at 7 to the underside of the plate 4 and are urged towards one another by a spring 8, the movement of each lever being limited by a slot and pin arrangement 10, 11. The inner face of each lever 6 is formed with a cam face 9 so that when the plate 4 is moved into contact with the throttle control levers 2 movement of the central throttle levers will cause them to bear on the cam faces 9 to urge the levers 6 outwards to a position where they overlap the guide slots of the outer throttle levers which are then prevented from opening beyond a limited slow running position. If full movement is applied to the outer throttle levers they will act as lateral stops to prevent outward movement of the levers 6 caused by pressure of the central throttle levers on the cam faces 9. A plate 19, secured to the underside of the plate 4, is apertured at 18 to engage a spring-loaded plunger 15, released by a trigger 12, to hold the plate 4 in its locking position. A cable control 20 is attached to the plate 4 and is coupled to the flying control surface locks to ensure simultaneous actuation thereof with the throttle locks. In an alternative arrangement (Fig. 6, not shown), the plate 4 does not slide but is pivoted at its end remote from the throttle levers, the cable 20 being connected to a lever attached to the plate 4.

Abstract: 901,081. Punching jacquard cards. DUNN ENGINEERING ASSOCIATES Inc. Oct. 22, 1959 (July 31, 1958 ; Aug. 20, 1958], Nos. 24727/58 and 26807/58. Class 142 (2). Card punching apparatus, particularly for carpet weaving, includes a drum 72, Fig. 1, for feeding a design sheet 65 line-by-line past a guide 74, reading of each line of the design being facilitated by a row of illuminated segments 82 which are switched on in succession, each segment exhibiting eight squares of the design. The operator presses in succession buttons 78 corresponding to the colours of the eight illuminated squares, an indication of the selection being given by a digital display 314 ; if a mistake is made, it can be corrected by operating the relevant cancelling switch 316 and then pressing the correct button 78. The information is passed through an encoding unit controlled by switches 302, which are pre-set in accordance with the desired relationship between the buttons 78 and the holes in the cards. The signals from the encoding unit control solenoids in a head 212, Fig. 17, which actuate rods 202 coupled by levers 206 to stops 202a which are thereby positioned over any punches 204 that are required to operate ; the head 212 acts simultaneously on a column of rods 202 corresponding to two tufts of the fabric and is automatically stepped from column to column until half the punches have been set ; a second head 212 then takes over to set the remaining punches. When a whole row of the design has been dealt with, a platen 208 is raised to punch a card 211. To cut cards for a cheaper carpet, pile can be omitted on selected squares of the design by operating a switch bar 324, Fig. 1, instead of a button 78.

Title: Improvements in reproduction of sound
IPC: B62D23/00
Filed: 1928-08-29
Abstract: 320,723. Beatty, W. E., (Bell Telephone Laboratories, Inc.). Aug. 29, 1928. Thermionic relays.-A method of reducing noise in sound-record reproduction coinsists in automatically de-energizing the receiver, such as a loud-speaker 4, during the reproduction of blank portions of the records when current of a certain predetermined value flows in the reproducer circuit. A sensitive relay device, such as a voice-operated relay, may be arranged to short circuit the loud-speaker or otherwise divert the reproduced currents whenever they fall to the noise level. In the arrangement shown in the Figure, an electron discharge device 7 of the kind described in Specification 189,12,5 is employed. The currents generated in a reproducer 1, which co-operates with a sound-record 2, are amplified at 3 and utilized to operate the loud-speaker 4 through a transformer circuit 5, 6. A portion of the current from the amplifier 3 is rectified at 8 and delivered to the magnetizing winding 9 of the device 7. A polarizing-winding 10 energized by a battery 11 is provided to supplement the magnetic field produced by the winding 9. When the only currents generated by the reproducer 1 are those due to surface noise, the magnetizing current in the winding 9 is small and the impedance between the anode 1 and the cathode 13 will be low compared with the impedance of the transformer 6 so that these currents are diverted through the electron discharge device 7. At higher currents, the magnetizing current in the winding 9 increases and with correct adjustment of the current in the winding 10 and the output of the rectifier, the transformer 6 offers the lower impedance and the corresponding sounds are therefore reproduced by the loud-speaker 4. The action of the electron discharge device may be made gradual by locating the cathode 13 eccentrically with respect to the anode 12.
