IPC: H04K1/02
Filed: 1923-08-22
Abstract: 221,932. Vickers, Ltd., and Ryan, C. P. Aug. 22, 1923. Controlling apparatus; calling ; thermionic modulating systems; secret and selective signalling systems; tone-frequency tuning arrangements; signalling by record-disc operated microphone.-In a wireless control system, impulses are sent at timed intervals at a predetermined acoustic frequency or frequencies together with interfering signals at other acoustic frequencies. The impulses actuate a receiver tuned to the signalling frequency or frequencies, and control a circuit which acts upon an oscillatory inertia member the period of which is that of the impulses and which builds up its oscillations until the desired operation is effected. The Figure shows a record sound disc Q cut with the desired operating and interfering signals and operating a microphone N arranged to modulate, high-frequency oscillations produced by the oscillator K and radiated from the antenna J. The operating signals are of two acoustic frequencies, and at the receiver affect a telephone H of loud-speaker type, near which are placed acoustic receivers S, S<1>, each tuned to one of the acoustic frequencies and carrying microphones s, which serve to excite, through chattering contact relays W, W<1>, electromagnets D, D<1>. An oscillatory inertia member A, having poles a<1>, is controlled by the electromagnets and is provided with a coiled spring C to determine its period. In the example shown it closes an electric circuit E. In a modification, the chattering contact relays w are replaced by transformers with rectifiers placed in the secondary circuit in addition to the windings D, D<1>. Specification 141,269 is referred to. In the Provisional Specification, Specifications 222,285, 223,696, and 224,621 are referred to.

Title: Improvements in or relating to photographic cameras
IPC: G03B19/04
Filed: 1958-07-03
Abstract: 838,861. Photographic cameras. KODAK Ltd. July 3, 1958 [July 5, 1957], No. 21360/58 -  Class 98(1) A camera is provided with mechanism for automatically actuating the shutter and advancing the film one frame, the mechanism comprising, in combination, a shutter shaft 36 adapted to actuate the shutter; a stub shaft 28 in axial alignment therewith; a spring 47 interconnecting said shafts, which can rotate the shutter shaft while the stub shaft is stationary; a film advance mechanism controlled by the stub shaft; first and second escapement mechanisms associated with shutter and stub shafts respectively, and adapted to limit the rotation of each to one revolution; means for releasing the first escapement. allowing the shutter shaft to rotate once to make an exposure, during which rotation it releases the second escapement allowing the stub shaft to rotate, which operates the film advance mechanism and re-tensions the connecting spring 47. The camera casing is divided into two compartments by a partition 2; one compartment (Fig. 2) contains the film transport and take-up mechanism, and the other compartment (Fig. 3) contains the shutteractuating mechanism, film drive and metering mechanism, and the main driving spring 13. The latter is initially wound by hand from core 14 on to a take-up drum 16. The tendency of the spring to return to its original position on core 14 provides the main motive force, rotating drum 16 anticlockwise. Driven from the same shaft 18 is a gear 19, which, by means of a train of gears 22, 23, and a spring clutch 25, turns the shaft 12 carrying a sprocket 11 which advances the film from the supply reel 5 to the take-up reel 6. The clutch 25 can be slipped by manual rotation of shaft 12 for initially loading and threading the film. The connecting spring 47 is initially tensioned by turning the cylindrical member 48 a sufficient number of times on the shaft 36, and then locking it to the shaft. The operation is carried out by depressing the trip member 45. This pushes down one end 44 of a bell-crank 41, which tilts about its pivot, an arm 40 at its other end disengaging from an ear 39 on a sleeve 38 secured to the shutter shaft 36, allowing the latter to revolve rapidly under the action of the tensioned spring 47. After one revolution, it is arrested once more by another leg 52 of the bell-crank. As the shutter shaft nears the end of its rotation, a cam 49 secured to sleeve 38 engages a leg 51 of a dog member 33, which pivots so that another leg 32 disengages from a lug 31 of a sleeve 30 fast with the stub shaft 28. The stub shaft, powered by the motor spring 13, is thus released to make one revolution, so driving the transport mechanism to advance the film one frame, and at the same time re-tensioning the spring 47. A flat spring 34 mounted on the casing urges the dog 33 back so that the leg 32 again intercepts the lug 31 after one rotation of the stub shaft.

Abstract: 976,690. Grinding. CINCINNATI MILLING MACHINE CO. May 29, 1963 [July 10, 1962], No. 21456/63. Heading B3D. [Also in Division G3] The wheel-head 11 of a grinding machine, adjustable on a screwed piston-rod 16 by a hand wheel 20, is advanced towards the workpiece 15, in response to movement of a hand lever 62 to a position determined by a ball detent 60a, until an abutment 16a on the pistonrod engages an adjustable abutment 47 whereafter the wheel head is caused to advance in correspondence with further movement of the hand lever. The piston-rod 16 carries a doubleacting piston 18, chambers 38, 40 on either side of which are always connected by conduits 37, 39 to annular grooves 35, 36 on a slidable sleeve 26 which is movable by pressure changes in a chamber 54 connected to a source of pressure 28 through an elongated port 56 and to sump through an elongated port 64 controlled by a pilot valve member 67. The chamber 54 is therefore maintained at an intermediate pressure which is opposed to the source pressure acting on a smaller area of the sleeve 26 in a chamber 53, and any reduction of area of the port 64 due to leftward movement of the pilot valve member raises the pressure in the chamber 54 causing leftward movement of the sleeve 26 until balance is restored by throttling of the port 56. With the parts in the positions shown, pressure from the source 28 entering an annular groove 31 on the sleeve 26 can pass to the groove 36 and chamber 40 to hold the wheel head retracted, but on leftward movement of the sleeve 26 the pressure and exhaust connections to the piston 18 are reversed, a valve member 27 remaining stationary, causing the wheel head to advance until the valve member 27 is brought to the lapped position by the abutments 16a, 47, whereafter the wheel head can only move in correspondence with the lever 62. In a modification, separate advancing and retracting pistons for the wheel head are provided and the hand lever, which operates the pilot valve through a cam, is movable about a second axis to operate a throttle valve in the conduit leading to the wheel head advancing piston.

Filed: 1930-07-16
Abstract: 358,606. Refrigerating. LEHMANN, B., 16, Schillingstrasse, Reinickendorf, Berlin. July 16, 1930, No. 21537. Convention date, Sept. 18, 1929. [Class 29.] Absorption systems.-For the removal of air and foreign gases, such as decomposition products of the refrigerant, from closed cycle absorption systems, the mixture of refrigerant vapour and foreign gases is led into direct contact with cooled weak solution in a vessel which may be isolated by valves from the refrigerating circuit, whereby loss of refrigerant is minimized when the foreign gases are discharged. The invention is described as applied to a system comprising a generator 1, a condenser 2, an evaporator 4, a reabsorber 3, a cold-producing generator 5 and an absorber 6. Vapour from the generator 1 passes to the condenser 2 and the liquefied refrigerant passes an expansion valve to the evaporator 4, whence vapour flows to the reabsorber. Strong liquor passes from the reabsorber through a heat exchanger 14 and a pressure reducing valve to the cold generator 5, from which evolved vapour passes to the absorber 6 and weak liquor is pumped back to the reabsorber. The weak liquor from the generator passes through a pipe 7 and interchanger to the air removal device 8 before reaching the absorber, from which strong liquor is pumped back to the generator. The weak liquor in pipe 7 is cooled by water or brine in a jacket 9 before it reaches the device 8 and is thus in a condition to absorb nearly all the refrigerant vapour from the gas mixture discharged through a valve 17. A throttle valve 21 is provided in the pipe 7 and a similar valve 20 in the absorber. A connecting pipe 10 with control valves 11, 12, 15 enables the device 8 to be used for discharging gases from the condenser and reabsorber. Gases may also be discharged by way of valves 15, 23 and a device 22 in the weak liquor pipe 13 from the cold generator to the reabsorber. When the pressure in the system is below atmospheric a water jet ejector may be used to effect the discharge of the gases.
