Title: Acceleration responsive device
IPC: G01H1/00
Filed: 1974-05-20
Abstract: 1468081 Vibration measurement ROBERT SHAW CONTROLS CO 20 May 1974 [21 May 1973]  22361/74 Heading G1G Acceleration-responsive apparatus comprises a switch which is tripped in response to acceleration above a threshold level; an electromagnetic device for resetting the switch after each tripping; a capacitor receiving a charge increment each time the switch is tripped and having a bleedpath across it; and a voltage comparator which disables the resetting if the voltage across the capacitor exceeds a predetermined value. In the embodiment shown, for monitoring vibration of powerplant, a shut-down or alarm signal is generated if a vibrational acceleration exceeds a threshold level sufficiently often within a given interval of time. On each occasion that the threshold is exceeded, switch 25 closes and supplies via emitter-follower Q2 a turn-on signal for SCR 17 after a brief delay determined by capacitor 29. The SCR energizes magnet coil 15 which resets the switch to its open position. If the closures of switch 25 occur at a sufficient frequency, the voltage accumulated across capacitor 40 rises above that at the junction of resistors 34, 37 and voltage comparator IC2 turns on transistor Q3. This acts via diode 31 and Q2 to remove the gate signal of SCR 17 so that re-set coil 15 is no longer energized. The turn-on of Q3 also acts via electro-optic isolator IC3 and triac 113 to remove A.C. power from the load. To avoid removal of the A.C. power by the apparatus responding to transients during start-up of the load, a delay circuit including capacitor 82 and voltage comparator IC1 ensures that no voltage C is applied to switch 25 until a pre-set time has elapsed from start-up.

Title: Improvements relating to amplifiers for recording apparatus
Inventor: WOOD LESLIE
IPC: H03G7/02
Filed: 1948-08-25
Abstract: 657,124. Automatic voltage control systems. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Aug. 25, 1948, No. 22400. [Class 38 (iv)] The gain of an amplifier is automatically reduced by means of a selector switch when the signal exceeds a predetermined value and is restored to an adjustable maximum when the signal falls below a predetermined minimum value. A D.C. amplifier A has a gain control potentiometer TR in its negative feed-back path, which is adjusted by a uniselector switch US1. Part of the output of the amplifier which is of negative polarity is applied (through a rectifier when the amplifier is not a D.C. amplifier) to the grid of a normally conducting valve V1A which with a normally non-conducting valve V1B forms a trigger circuit. If the amplifier output is sufficient the anode current of valve V1A is cut-off and current flows through valve V1B. This reduces the bias on the grid of a pentode valve V2 so that voltage pulses applied from a multivibrator valve V4 through a D.C. restoring valve V3 to the suppressor grid cause pulses of current to flow in the relay winding RL1 in the anode circuit. Successive operations by these pulses of the relay contact RL1<SP>1</SP> step the uniselector to reduce the gain of the amplifier until the signal amplitude is insufficient to maintain valve VIA non-conducting. Part of the output of the amplifier is also supplied to the grid of a further normally conducting valve V5 so that when the negative output voltage from the amplifier falls below the level which renders the valve non-conductive a relay RL2 in its anode circuit operates and its contact RL2<SP>1</SP> breaks the direct connection between grid and cathode of valve V6. The charge which had built up in condenser C2 due to the voltage across the cathode resistor slowly leaks away and valve V6 slowly returns to its non-conductive state to release a relay RL3. Contact RL3<SP>1</SP> applies a voltage from a source B to a second bank S2 of the uniselector which is arranged to cause its contact to " home " to a preselected maximum gain position determined by the position of the gap in the shorting plate of a switch SW<SP>1</SP>. Additional banks of the uniselector may be used for other purposes such as range marking.

Title: Method of and apparatus for treating cigar bunches
IPC: A24C1/20
Filed: 1932-08-12
Abstract: 396,230. Cigar-making machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (International Cigar Machinery Co.; 5520, 2nd Avenue, Brooklyn, New York, U.S.A.) Aug. 12, 1932, No. 22606. [Class 130.] A cigar bunch is treated by shaping the previously formed bunch and forcing dry air or gas to flow into, through or over the bunch while it is being shaped in the mould. The air or gas may be heated or chilled before being used, and is supplied under pressure and/or drawn through by suction. The method enables soft, well-filled bunches to be produced with a minimum amount of tobacco. As shown in Fig. 1, an intermittently rotating turret shell 10 carries mould elements 17, 18. Compressed air is passed through a filter or moisture trap 38 and an electric heating chamber 39 to a chamber 43 on the end of the moulds 17, 18, and a chamber 44 at the head end of the moulds is connected to a suction fan 46. In order to allow the air to be passed over the surface of the bunches, cam tracks 20, on which run rollers 19 carried by the upper mould members 18, are shaped to lift the members 18 at intervals during the rotation of the turret. For cigars having tightly wrapped heads, the head is pierced by a needle 49 actuated by a cam 55 on a rotary shaft 51. The bunches are removed from the moulds by pins 23, Fig. 5, carried by an arm 24 on a vertically sliding rod 25, Fig. 1, actuated through a link 27 by a cam. The bunch is engaged by clamp fingers 29 on an arm 30 and transferred to wrapping mechanism 31, the shaft 32 carrying the arm 30 being connected by sprocket gearing 35 to the shaft 37 carrying the clamp fingers. In a modification, the heater 39 is replaced by a chamber surrounded by dry ice or provided with other refrigerating means, moisture being precipitated from the air by a baffle in the chamber. In a further form, a stationary mould of wood &c. is fitted between a pressure chamber and a suction chamber connected respectively to a source of dry compressed air and to a suction fan.

Title: Improvements in cinematograph projectors for miniature films
IPC: G03B1/56
Filed: 1953-08-17
Abstract: 761,138. Kinematograph projectors. SHAMAH, I: Aug. 12, 1954 [Aug. 17, 1953], No. 22613/53. Class 97(1) In a projector in which the intermittent film feed is produced by tension produced by the take-up spool, the film being permitted to feed through the gate one frame at a time, the film passes to the take-up spool over a guide on a pivoted spring- loaded support so that the guide moves under the action of spring tension to detach a film perforation from a locating member between the gate and the guide. In the form shown the lamp 19 is carried in a mount 15 secured by a screw with nut 18c to be adjustable transversely of the optical axis in a slot in a bracket 18 secured by a screw 17, to a mounting plate 16. the screw 17 engaging a slot to permit axial and rotational adjustment. The lamp is fed from a battery 6 through a switch comprising a sliding contact bar 9. The mount of the condenser lens 20 is secured by a screw 23 engaging a slot 24. The film gate is formed by the front of this mount and apertured plate 32. The projection lens 25 is carried on a mount movable on a dovetail slide by a friction wheel.29 operated by an external handle 30. A reflector 35 is carried on a stem 36 rotatable to permit the projection beam to emerge from an aperture 34 or to reflect it to form an image on a screen 36. The film from the feed spool 3 passes through the gate and round a roller 49 on a bell crank 47 pivoted at 48 and acted on by a spring 51 which tends to hold it in the position shown dotted to engage a film perforation on a fixed claw 54. The film is led over a roller or sprocket 50 to the take-up spool 5 rotated by a handle 46. The film tension increases and moves the bell crank against the tension of the spring 51 until the film is freed from the claw 54 and moves forward until the next perforation is engaged with the claw by the action of the .spring. Alternative anchorages 53 are provided for the spring. The film is rewound by transferring the handle 46 to the feed spool spindle, the film tension keeping the film clear of the claw 54 during rewinding. In another embodiment the claw 54 is carried by a spring-loaded pivoted lever engaged by an abutment on the bell crank 47 as the latter is moved by the film tension, to remove the claw from the film perforation. In a further embodiment the film passes from the gate round a film sprocket integral with a ratchet wheel co-operating with a spring-loaded pawl which carries a film roller so that increasing film tension frees the wheel to rotate by one tooth. Adaptors are provided to enable the film spools to accommodate the spools used for winding films of various width. Two projectors may be coupled for sterescopic use.

Title: Fuse for shells, bombs and the like
IPC: F42C15/22
Filed: 1924-09-26
Abstract: 222,495. Pantoflicek, B. Sept. 26, 1923, [Convention date]. Projectile fuzes are armed by centrifugal force set up by the rotation of the fuze or a part thereof during flight by means of wind vanes, and are fired on impact by the cessation of centrifugal force, or by linear or rotational momentum of a hammer, or by the direct impact of a firing-pin on the target. As shown in Fig. 1, the fuze comprises a spindle 5, which is rotated during flight by a windmill 11. This rotation is transmitted to a body 20 containing spring plungers 21. which, under the centrifugal forces thus set up, compress their springs 22 and unlock the spindle 5. On impact, the direct action of the blow drives the spindle 5 with its firing-pin 15 on to the detonator 16. In a modification, Fig. 2, the windmill 11 is enclosed in a recess in the nose of the fuze, and the firing-pin 15 is carried by the rotary body 20 and strikes the detonator 16 when the body 20 continues to rotate while the rotation of the projectile is slowed down by the impact. In another modification, Figs. 3 and 4, the whole fuze is rotated by the windmill 49, and the fuze is fired by the continued rotation of a ring 53 carrying firing-pins 15, while the rotation of the rest of the fuze is slowed down by the impact. Two modifications of this latter arrangement are described, in which the fuze is fired on impact by the forward movement of a momentum pellet, and by the return of a spring plunger by its spring when centrifugal force ceases, respectively.
