Title: Control means for wireless apparatus
IPC: H01H21/22
Filed: 1945-01-03
Abstract: 587,097. Adjusting wireless apparatus. ROBINSON, E. R., and . MASTERADIO, Ltd. Jan. 3, 1946, No. 237. [Class 40 (v)] [Also in Group XXXVII] The rotation of a control member, which is suitably mounted for both rotary and longitudinal motion, causes the adjustment of a volume control potentiometer (or tuning condenser) and its longitudinal motion causes the step-by-step rotation of a ratchet-wheel and its associated switching means for wavelength change and/or station selection. In Figs. 1 and 2, a sleeve 3, fixed to the control shaft 1 'is capable of rotary and longitudinal motion within a bushing 6. Rotary motion of the sleeve is transmitted to a potentiometer control shaft 8 by a pin 11 co-operating with a longitudinal slot 10 in the shaft 8. Rotation of the ratchet wheel 18 is effected by the longitudinal movement of the sleeve 3 and of the pawl 15 which is freely mounted on the sleeve but biassed towards the ratchet wheel by a spring 12. This spring also causes the return motion of the sleeve 3 which is limited by the contact of the integral flange 14 with the bushing 16. The rotary switch 21 adjusted by the ratchet wheel is located in its different operative positions by the ball-and-socket mechanism 24. The potentiometer 9 may also include the usual on-off switch.

IPC: G03D15/00
Filed: 1924-01-03
Abstract: 212,225. Goerz Photochemische Werke Ges. March 3, 1923, [Convention date]. Films; colouring and finishing.-Photographic and kinematographic films are dulled by applying a fine spray of varnish so as to produce a stippled effect. Positive or negative film or the crude stock may be treated on one or both sides. The varnish or lacquer may consist of a cellulose solution to which a soluble metal salt, such as calcium may be added. In one form, a one per cent solution of nitro-cellulose in half-and-half ether-alcohol is sprayed on the film through a fine nozzle. The film may be coloured simultaneously by adding a suitable pigment to the varnish. The process is applicable for the removal of scratching on kinematograph films, and for covering up any coarseness of grain of negatives due to the quality of emulsion used.

Title: Improvements in instruments for determining the efficiency of fluid heaters
IPC: G01K17/16
Filed: 1949-01-07
Abstract: 656,538. Measuring boiler efficiency. BAILEY METERS & CONTROLS, Ltd. Jan. 7, 1949, No. 506. Convention date, Jan. 9, 1948. [Class 40 (i)] In a system for measuring and recording the efficiency of a steam generator, a voltage proportional to the rate at which heat is being taken up by the water is automatically balanced by a fraction of a voltage representing the rate at which heat is supplied to the furnace, this fraction representing the efficiency. As shown, electrically controlled thermometers 10, 16 responsive respectively to the temperatures of the feed water and the steam control the positions of the cores 11, 17 of differential transformers via cams 34, 33 which ensure output voltages across resistors 27, 28 proportional to the heat per unit mass in the feed water and steam, respectively. Adjustable portions of these voltages are applied in opposition to a resistor 30 across which a voltage is thus produced representative of the gain of heat by the water per unit mass. A slider 35 controlled by a flow meter selects a voltage from this resistor representative of the rate of utilization of heat. Flow meters O, G, measuring the rate at which fuel (of two different kinds) is being supplied to the furnace, control the cores of similar differential transformers, the outputs of which, with corrections for the calorific values of the respective fuels, produce a voltage across resistor 57 representative of the rate at which heat is being given to the furnace. The proportion of this voltage selected by a slider 58 is kept automatically equal to the voltage selected by slider 35, e.g. by a motor control system, as described in Specification 660,105, and the position of the former slider, which represents efficiency, is indicated and, if desired, recorded. In a modification, Fig. 3 (not shown), the voltages representing the heat of the steam and feed-water are obtained directly from a pair of bridges having an arm of each constituted by a resistance thermometer element.

Title: Improvements in or relating to electrostatic storage of information
Inventor: WILLIAMS FREDERIC CALLAND
IPC: H01J31/60
Filed: 1951-01-09
Abstract: 705,508. Pulse storage circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Jan. 9, 1952 [Jan. 9, 1951], No. 649/51. Addition to 657,591 and 705,474. Class 40 (6) In a pulse storage circuit in which one of two charge patterns are set up on areas of the screen of a C.R.T. as described in Specification 705,474, the change from the defocused to the focused condition is made relatively slowly. This ensures proper operation when the beam is deflected as there is then a tendency for the focused spot not to be in the centre of the defocused spot. The circuit employed is a modification of that described in Specification 705,482. The defocusfocus wave is as shown in Fig. 3(c) to cause focusing to occur during the long pulse of the dash-wave (b) but not for the dot wave (a). The dash wave can be shortened, as shown, by the use of a large amplitude pulse. This is achieved by the circuit of Fig. 4, wave (e) being fed to the anode of diode D43 and wave (f) being fed to terminal 37. During the negative-going parts of the waves D43 or D42 are held cut-off so that diodes D21 or D41 conduct to connect either resistor R1 or R3 in parallel with resistor R2. By this means the three levels of wave (b) are established. If the change in intensity of the beam is sufficient to cause focusing, wave (b) may be shaped as in the dotted curve. Specification 645,691 also is referred to.

IPC: C10B21/20
Filed: 1917-07-06
Abstract: 118,777. Merz & McLellan, Michie, A. C., and Weeks, E. G. July 6, 1917. Power-generating systems. - Coal is destructively distilled by superheated steam and the resulting products of distillation condensed and cleansed, the gas being used in an internal-combustion engine, and the coke from the distilling-retort being passed directly to a gas-producer, or being in part passed directly to a boiler which generates steam for power purposes. The producer is supplied with a steam blast heated by the exhaust of 'the internalcombustion engine, the blast for the distilling-retort being superheated by gas supplied from the retort or producer. The cooling- water from the engine may be used to condense the first distillates from the retort gas, and this water is then used as feed-water for the boiler which supplies the blasts. As shown, a conical retort A, lagged with magnesia A<4>, and kieselguhr A<3>, is fed with coal from a hopper A<1>, and with superheated steam from a pipe F<1>. A discharging-device A<2> feeds the coke continuously to a producer B, or in parts to a boiler which generates steam to be utilized as desired for power purposes. The gas from the producer B passes by a pipe B<3> to a stripping- device C, and thence the gas passes to an internal-combustion engine D. The exhaust gases from the engine D pass by a pipe D<1> to a boiler E, and the steam thus generated passes direct to the producer B and through a superheater F to the retort A. The engine D is cooled by water supplied by a pump L<1> and pipe K, and from the water jacket the warmed water passes through a condenser H, in which the first distillates from the retort gas are collected, and thence this feedwater passes through an economizer E<1> to the boiler E. The gas passes from the condenser H to a second condenser J, which is cooled by water tapped off the main K, the condenser J also delivering its distillates to the same well M as the condensed H. The unconcensed gas passes to the stripping-device C, and thence to the engine D. The gas for the superheater F is tapped off the pipe C<1>, or may be supplied either from the producer gas or retort gas.

Filed: 1917-01-18
Abstract: 112,665. Anderson, W. Jan. 18, 1917. Regulating; valves; valves-gear.-To facilitate starting and slow running in an engine using crank chamber compression, a portion of each charge is rejected from the cylinder during the compression and stored in reservoirs d which return the rejected charges towards the ends of the working strokes. Communication between the reservoirs and the cylinder is controlled by a valve h, the point of closing of which determines the amount of charge delivered to the reservoirs. The valve carries a piston k, which is open on its upper face to a passage containing a storage chamber n communicating with the crank chamber through a hand-controlled valve p<1>. At starting, the valve p<1> is closed and a non-return valve q, which is normally held to its seat by a rod y, is left free to open, the crank chamber then charging the reservoir o through the by-pass r. The pressure in the reservoir holds the valve h in its lowermost position until it is reduced by opening the valve p<1>. After starting, the valve p' is opened more or less, and gases escape from the reservoir o to the crank casing, the pressure in the reservoir determining the pressure at which the valve p<1> is closed to cut off communication between the chambers d and the cylinder. Leakage of gas from the cylinder to the reservoir o takes place through a passage k<1> in the piston k, the leakage being balanced by the gases escaping past the valve p' into the crank casing. The valve p<1> and the rod y of the valve q are actuated by Bowden wire mechansm. The reservoir o may be charged by a separate pump and the valve h. may be held open by a screw inserted in the casing x'.

Abstract: 757,739. Servo-assisted braking systems. DUNLOP RUBBER CO., Ltd. Dec. 31, 1954 [Jan. 13, 1954], No. 949/54. Class 103 (1). In a servo-assisted braking system, a disc 1 is secured to the transmission shaft 2 of a vehicle and is braked by pads of friction material associated with a caliper member 5, secured to a torque member 3 which is permitted angular movemen between predetermined limits. When the master cylinder 10 is actuated by brake pedal 19, fluid pressure is forced via pipeline 9 into the piston and cylinder mechanisms 8 associated with the caliper member 5, forcing the pads of friction material into frictional engagement with the disc 1 which is rotating with the transmission shaft 2. The ensuing torque causes the caliper member 5 to commence rotating in the direction of rotation of the disc, between predetermined limits, thus angularly moving connecting-rod 12 to pivot link 13 about its support to pressurize hydraulic liquid in the servo-cylinder 15 and thereby apply the vehicle wheel brakes 18 operatively connected thereto. The servopiston 14 is effective to pressurize the wheel brakes 18 irrespective of the direction of motion of the caliper member 5 and disc 1. The wheel brakes 18 may be of the disc or drum type. In a further arrangement, described in the Specification, the friction pads associated with the caliper member 5 are mechanically operated; the movement of the caliper member 5 actuating a servo-cylinder and associated brake mechanisms as previously described. In a further embodiment, described in the Specification, a lost-motion connection is provided between the caliper member 5 and the servo-piston 14 such that the construction would be single-acting only; this embodiment being suitable for a pneumatically-operated braking system. Specifications 688,382 and 747,965 are referred to.
