Title: Improvements in and relating to the production of sweetmeats
IPC: A23G3/02
Filed: 1938-05-03
Abstract: In the production of an aerated fondant-like compound, a mixture consisting of a syrup in which dextrose is substantially insoluble and an edible colloid having beating properties, e.g. gelatine, is aerated by beating, and a substantial quantity of finely divided crystalline dextrose hydrate is then beaten into the mixture under conditions such that the crystals will remain substantially unchanged in the product.  In an example, a syrup is made by dissolving together 3,82 per cent by weight of sucrose, 10,25 per cent of corn syrup, 9,15 per cent of invert sugar, 3,82 per cent of dextrose and 5,13 per cent of water.  To this is added ,65 per cent of gelatine, 1,96 per cent of water to dissolve the gelatine and 65,22 per cent of finely divided dextrose hydrate.  The dissolved gelatine and syrup are beaten for from 5 to 7 minutes until a soft, marshmallow-like substance is produced.  The dextrose hydrate is then added and the mixture beaten for about 1 minute.  In another example, completely hydrogenated fat is beaten into the mixture with the dextrose hydrate.  Butter or lard and colouring matters, flavours, chocolate or cocoa may be added.  The gelatine may be replaced by egg-albumin, whey protein, or agar-agar.

Title: Improvements in or relating to circuit arrangements for use in colour television receivers
IPC: H04N11/14
Filed: 1965-03-30
Abstract: 1,062,959. Colour television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. March 30, 1965 [April 2, 1964], No. 13416/65. Heading H4F. In a receiver for the N.T.S.C. system in which colour images are reproduced by a cathode-ray tube 32 having a non-linear modulation characteristic in response to gamma-corrected signals applied through a wide-band luminance channel 30<SP>1</SP> and a narrow band chrominance channel 8, the luminance of the reproduced image being a function of both the luminance and chrominance signals, undesired variations in image luminance, which occur during colour transitions due to the inability of the chrominance channel to transmit the necessary high-frequency signal components, are prevented by twice differentiating the chrominance signal in CR (or, alternatively, LR) networks 23 and 26 to obtain a correction signa which is combined with the luminance signal in an adder 29. The Specification includes an analysis of the luminance error by which it is shown that the desired correction signal consists of a second differential component, which is obtained as described above, and a further component directly proportional to the chrominance component. This further component is provided by the chrominance component which passes directly through the luminance channel as a consequence of the location of the chrominance component in the upper part of the luminance signal spectrum. Cathode-ray tube 32 comprises either a Lawrence or beam-indexing tube. Accordingly, the signals are converted to dot-sequential form with the aid of a circuit 31 in which the chrominance signal is (a) remoulded to symmetrical form and (b) demodulated to derive a M-Y correction signal. The output of circuit 31 is applied through a low-pass filter 36 and combined with the luminance signal in an adder 37. In the case of a Lawrence tube blanking (34) and beamswitching (sin # s t) signals are also provided. Delay line 30<SP>1</SP> equalizes the delay in narrow-band circuit 8 and differentiation networks 23, 26, whilst delay line 39 equalizes the delay in lowpass filter 36. If circuit 31 is based on balanced push-pull arrangements, filter 36 and delay line 39 may be dispensed with. In a modification, the correction signal may be derived from the dot-sequential signal at the output of filter 36. Differentiation networks 23 and 26 are transferred to the output of filter 36, adder 29<SP>1</SP> is placed immediately preceding adder 37 and delay networks 30<SP>1</SP> and 39 are combined into one. Another embodiment of the invention, Fig. 1 (not shown), which makes use of a threegun cathode-ray tube, is generally similar to Fig. 2 except that the chrominance signal is applied to two synchronous detectors and a matrix network for deriving three simultaneous colour-difference signals.

Title: A system of hydraulically working the brakes of motor vehicles
IPC: B60T13/16
Filed: 1922-05-13
Abstract: 202,378. Formaca, G. May 13, 1922. Brakes, arrangement and disposition of; hydraulic transmission.- Relates to hydraulic brakes for motor vehicles in which a pump geared to the wheels normally circulates liquid freely in a circuit open to the brake cylinders, the pump circuit being closed to establish pressure in the cylinders. An arrangement of differential gear acting as equalizing mechanism for brakes on the four wheels of a vehicle and means whereby the brakes may be directly applied by the lever which controls the hydraulic system are also described. The gear wheel pump 20 having one of its gear wheels on the transmission shaft 21 normally circulates liquid from a reservoir 22 past the valve 100 and has its delivery pipe 12 open to the brake cylinders 13. The valve 100 is connected with a pedal 8 by a rod 9 in which a spring 10 is interposed. When the valve is closed a pressure is established in the brake cylinders which is limited by the compression of the spring 10 applied by the pedal and which falls with the speed of the vehicle. A safety valve 101 is also provided. The arrangement shown in Fig. 1 comprises two cylinders each having a pair of pistons, each piston being connected to the brake on one of the wheels by rods 4, 7 and lever 17. The rear brakes can also be directly applied by the pedal 8 and also by the hand lever 26 by the rod 19, lever 28 and clutch device 18. In a modification, Fig. 4, a single cylinder is used and this cylinder together with the pump is disposed within a casing 111 which forms the reservoir. The piston rod 114 is in this case connected to a shaft 116 which carries on an arm 120 the pinion 119 of a differential gear A which includes also the toothed segments 118a gearing with the pinion 119 and mounted upon sleeves 117, 118. The sleeve 118 is connected by the arm 121 and rod 122 with the arm 123 carrying the pinion 124 of a second differential gear the toothed segments of which are secured to shafts 125, 126 connected to the brakes on the rear wheels. The sleeve 117 of the differential gear A has an arm 127 which is connected to the arm 128 carrying the pinion 129 of a third differential gear the segments of which are mounted on sleeves 130, 131 connected to the brakes on the front wheels. The pressure on the brakes of the four wheels is thus equalized. To permit direct actuation of the brakes by the pedal 8 which controls the valve of the hydraulic brake, the .shaft 8<a> of the pedal has an arm 8<b> which engages the arm 120 of the differential gear A. The rear brakes may also be independently applied by a hand lever 26 secured to a shaft 134 provided with an arm 133 adapted to engage a slide 132a secured to the rear part 122a of the rod which is connected to the differential gear of the rear brakes. The: rod 122 has secured thereto a slide 132 adapted to engage the slide 132<a>. The several differential gears may be disposed within a casing which may be the gear box.

Abstract: 759,600. Abrasive band machines. ROLLS-ROYCE, Ltd. May 13, 1954 [May 14, 1-953], No. 13591/53. Class 60 Apparatus for surface finishing a curved surface, such as that of a turbine or compressor blade 70, Fig. 12, comprises a work holder, a flexible abrasive carrier 41, Fig. 1, and a pressure-nuid-supply member 105, Fig. 7, disposed on the opposite side of the carrier from the work holder and having a contour 106 shaped to the form of the surface to be finished and provided with fluid delivery channels or apertures 107 to deliver pressure fluid to the back surface of the carrier 41. The carrier, which may be emery cloth, is clamped at 40 to the two ends of a chain 30 tensioned by pneumatically-loaded sprockets 36 and a jockey sprocket 34 and reciprocated by a sprocket 29 connected by a universal coupling 50, Fig. 2, and a chain drive 53 to a wheel 58 which is given an oscillating motion by a link connection and a continuously-rotating disc 56 mounted on the shaft of an electric motor 55. The operative portion of the carrier 41 is renewed for each workpiece by releasing the clamps 40 and operating supply and takeup reels 42, 43. When a concave surface is to be finished, the workpiece is mounted on a vertcally slidable holder 65 loaded by a weight 69 and the member 105 on a dovetail slide 45; for convex surfaces the arrangement is reversed. The member 105 may be made of nickel plated cast iron with a contoured rubber surface bonded thereto or entirely from a rigid material, a silicone grease being applied as lubricant between the member and the carrier 41. Pressure air or liquid is fed to separate chambers 109, 110 and 111, Fig. 8, by ducts 112, 113 and 114 supplied by a changeover valve actuated in accordance with the movement of the carrier 41 relative to the member 105 to avoid undue loss of pressure fluid. For finishing the surfaces of the blade 70 adjacent the platform 71, 72, the carrier 41 travels along lines 73 during part of the finishing operation and then the relative positions of the blade and carrier are adjusted so that the carrier travels along lines 74. To enable this adjustment to be effected, the sprockets for supporting and driving the chain 30 are mounted on a beam 28 which is periodically swung about vertical pivots 24, 25 by an adjustable crank mechanism 86. This mechanism is driven through bevel gearing and a belt 77 by an electric motor controlled by micro-switches and limit switches 98, 99. The micro-switches are actuated alternately by cams rotated by worm and belt drives from the motor 55 to start the motor for the crank mechanism while the limit switches 98, 99 are actuated alternately by the beam 28 to stop this motor when the beam has reached its new angular position. The blade and pressure-nuid-supply member may be adjusted angularly instead of the carrier 41, and an endless abrasive band may be used. Specification 759,642 is referred to.
