Abstract: 771,613. Kinematograph apparatus. BERTONI, V. Sept. 10, 1954 [Sept. 12, 1953], No. 26332/54. Class 97(1) [Also in Group XI] A filter in a light projector comprises a transparent member rotatably mounted in the light path and means for rotating or oscillating the member, a portion of which is immersed in a cooling liquid which is removed from the portion of the surface of the transparent member in the light beam. The system shown comprises two lamphouses 1 with arcs 2 and reflectors 3, the light beams being reflected by inclined mirrors 4 into a common condenser 8. The mirrors 4 are cooled by a circulating liquid entering at 5 and leaving at 6. The light beam from the condenser passes through a cell 9 through which circulates water or an infra-red absorbing liquid. The beam then passes through a transparent disc 13, rotating about an axis 13<SP>1</SP>, the lower half being immersed in a bath 12 of circulating liquid. Liquid is removed from the disc as it leaves the bath by wipers 14. The beam then passes through the film 16 and objective 17. Additional cooling is provided by fans 16<SP>1</SP> and air suction means 18. The beams striking the mirrors 4 may be cooled by discs similar to 13, which discs, three in all, may be the only cooling used. A similar disc may be used to cool the beam from a single lamphouse. Several such discs may be used in sequence and pairs may form cells containing an infrared absorbing liquid such as ferrous sulphate.

Abstract: 723,951. Self-levelling arrangement. FERRANTI, Ltd. Oct. 20, 1953 [Oct. 21, 1952], No. 26349/52. Class 113 (1). Equipment for maintaining unidirectional the axis 11 about which a component mounted on an unstable base 4 is required to rotate comprises a bracket 1 adapted to rotate about an axis 3 which is fixed relative to the base 4, a universal joint 9 for coupling the component to the bracket in such manner that the axis 11 and the axis 3 always intersect at the centre of the coupling, linkage means 13 for adjusting with respect to axis 3 the polar co-ordinates of a controlled point 12 of the component on the axis 11 remote from the coupling and means including pinions 5, 6 for rotating the bracket 1 about its axis 3 so as to rotate, by means of the coupling 9, said component about its axis 11 in the required continuous, intermittent or oscillatory fashion. The linkage means 13 may take the form in which inner and outer shafts 14, 15 coaxial with axis 3 have secured thereto a pinion 19 and an arm 16 respectively. Pinion 19 engages by way of an idle pinion 20 a pinion 21 secured to an arm 17 pivotally secured at the free end of arm 16 for rotation about an axis 18 parallel to axis 3. The gear ratio between pinions 19 and 21 is 2 : 1. The free end of arm 17 carries a pin 22 engaging a socket (not shown) in the component, this socket including the point 12. The distance between pin 22 and axis 18 equals the distance between axis 18 and axis 3. Hence when inner and outer shafts 14 and 15 are rotated together, pin 22 is carried round axis 3 at a constant radius from it, whereas when shaft 14 is held stationary and shaft 15 is rotated, pin 22 describes a purely radial line with respect to axis 3. These motions of the shafts, which thus central the polar angle and polar distance of the point 12, are effected by differential gears 31, 32 actuated by a pair of gyros (not shown). Specification 709,107, [Group XIX], is referred to.

Title: Improvements relating to electric starting systems for internal combustion engines
Filed: 1945-10-15
Abstract: 602,399. Starting prime movers. C.A.V., Ltd., and BEVIS, W. A. Oct. 15, 1945, No. 26895. [Class 38 (iv)] In an electric starting system for an internalcombustion engine of the kind wherein the starting motor a is supplied, under the control of a push-button d, from a battery b normally charged by an engine-driven generator h, an electromagnetic switch e-g so controls the battery-motor connections that the motor cannot be re-energized once the button d has been released and the engine is running. The switch comprises normally closed spring-loaded contacts e in series with the button and starting contactor coil c, the contacts being also under the control of opposed windings f, g which are energized, respectively, by the battery and generator. Starting from rest, closure of button d energizes contactor c and the engine is cranked by the motor. Winding f is also energized and assists the spring loading on contacts e. When the engine fires, winding g is energized by the generator, but contacts e remain closed as the effect of winding g is insufficient to overcome the combined action of winding f and the spring loading. Release of button d de-energizes winding f and contacts e now open under the action of winding g, thereby preventing further actuation of starting contactor c by the button until the engine has been again brought to rest.

Title: Improvements in apparatus for controlling automatically the supply of fluids under pressure
IPC: G05D16/20
Filed: 1936-10-06
Abstract: 483,010. Actuation of switches. BARNETT & FOSTER, Ltd., RAYMOND, C. W. Oct. 6, 1936, No. 27142. [Class 38 (v)] [Also in Group XXXV] Movement of a switch-arm 21 is effected by a diaphragm 16 subject to the opposing actions of gas pressure and a spring 21<1>. A decrease in gas pressure allows an upward movement of diaphragm 16 so that a rack 18 attached to the diaphragm causes rotation of a pinion 20 frictionally secured to an arm 21 which it moves to bring contact 8 to bear on a contact 7. Closure of the contacts 7, 8 causes operation of means for increasing the gas pressure so that the diaphragm is moved downwards and the contact 8 is moved away from the contact 7, and if the pressure becomes excessive the contact 8 is brought to bear on contact 38 causing operation of means to shut off the gas supply. The pinion 20 is loosely mounted on the spindle on which arm 21 turns and is held in frictional engagement with this arm by a spring or is secured thereto through a friction clutch. The switch may be adjusted to close contacts 7, 8 at a higher pressure by moving the arm 21 with a plunger 32 to close these contacts and holding it in this position until the pressure has risen to the desired value. To adjust the switch to operate at a lower pressure, operation of the means for increasing the gas pressure on closure of contacts 7, 8 is prevented and the pressure allowed to fall until the desired minimum pressure is obtained. The chamber 15 and diaphragm 16 may be replaced by a cylinder containing a piston.

Title: A method of and apparatus for converting an optical image into a television signal
Inventor: FAIRHURST HAROLD ALFRED
IPC: H04N9/07
Filed: 1957-08-29
Abstract: 897,911. Television. MURPHY RADIO Ltd. Dec. 1, 1958 [Aug. 29, 1957], No. 27270/57. Class 40(3). The invention relates to an arrangement for producing a chrominance modulated subcarrier wave which is independent of variations in the speed of scan of the pick-up tube. In the described embodiment image light is directed on to the photo-cathode 9 (Fig. I) of an image type pick-up tube via a colour filter 11 and a glass plate 12, the filter comprising, as shown in Fig. 3, Red, Green and Blue filters 13, 14, 15 respectively, separated by black strips 17 and bordered by opaque white strips 16 whilst the glass plate 12 is formed with a plurality of cylindrical lenses extending at right angles to the direction of line scanning and of such focal lengths that each lens forms an image of filter 11 on the photo-cathode 9 with the borders 16 of adjacent images overlapping. In operation, the surface of filter 11 adjacent the tube is illuminated by a source 19 so that the output signal of the tube consists, as shown in Fig. 4, of a series of pulses 21 representative of "whiter-than-white" due to the illumination of the white strips 16, "black" signals 23, 25 due to the black strips 17 and Red, Green and Blue signals 22, 24, 26, respectively due to the strips 13, 14, 15. For carrying out the present invention such output signal may be modulated on an auxiliary carrier wave but, instead, the beam of the tube may itself be modulated by such wave. Fig. 7 shows the latter arrangement in which the beams of the tube is modulated by a carrier wave of frequency f 1  + f, the desired sub-carrier frequency being f and f, being a pilot oscillation of approximately f x 10. The camera output then consists of f 1  + f modulated by the image light transmitted through filter 11 together with a frequency f 2  due to the "whiter-than-white" strips 16. After demodulation in 34 a limiter 33 selects the tips of the "whiter-than-white" pulses and feeds them to a filter 35 which supplies an oscillation of frequency f 2  to a mixer 39 to which is also supplied the upper side band of the total output signal from the camera, viz f 1  + f + f 2 , a limiter 37 excluding the "whiter-than-white" pulses. The lower side band, viz. f 1  + f, of the mixer output is selected by a filter 41 and supplied to a further mixer 42 in which it is combined with the pilot frequency f 1  to produce the difference frequency consisting of a chrominance modulated sub-carrier of frequency f which is independent of variations in the frequency f 2 , i.e. the line scanning rate of the pick-up tube. The luminance signal which is produced by passing the output of demodulator 34 through a L.P. filter 36 is combined with the chorminance signal in adder 43. To obtain precisely constant luminance a portion of the signal f 2  is reversed in phase and added to the modulated sub-carrier so as to convert the signals due to the white strips 16 into black signals similar to those due to the black strips 17.
