Title: Improved method and means for cooling sweetmeats
IPC: A23G7/02
Filed: 1923-08-14
Abstract: 202,634. Bentz, H. Aug. 15, 1922, [Convention date]. Cooling-chambers.-An apparatus for cooling sweetmeats, such as chocolates, comprises an endless conveyer, leading from the coating machine, carrying the articles through a cooling-chamber the upper part of which is cooled by air and the floor of which is cooled by a chilled liquid. The conveyer 31 leads through an aperture 33 and over drums 32, 20, the latter being held in sliding bearings 14 and rotated by worm gearing 19 from a shaft 18 driven from the coating machine. Chilled air is circulated through the chamber 3 by an exhaust fan, deflector plates 39, 41 being fitted in the inlet and outlet air pipes 38, 40 respectively. The conveyer passes over the floor of the chamber which is formed of a number of interconnected tanks 7 through which chilled liquid is circulated. The conveyer travels through the chamber in the opposite direction to the cooling fluids and passes over the top of the interconnected tanks, the articles being cooled by the action of the air and the liquid. The tanks are connected by pipes 8 arranged to prevent air being trapped and form a delivery platform 9 from which the articles are removed from the machine.

Abstract: 167,500. Tigerstedt, E. M. C. Aug. 7, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Synchronism indicators. - Means for indicating synchronism or lack of synchronism between two shafts 25, 125 or the like comprise identical means on each shaft whereby once in each revolution lamps at both the transmitting and receiving ends are lit up from sources at such ends and a further lamp is lit at the receiving end by means of a current arising from the completion of a circuit at the transmitting end. Constant relative positions of the two lamps such as Á<1>, 117<1> at the receiving end indicates maintenance of synchronism. The shafts 25, 125 carry rings 26, 126 with cam-projections 27, 127 making circuit between springs 28, 29 and 128, 129 at each revolution and rings such as 30, 31, Fig. 2, with brushes 35, 36, 135, 136 running over two series of insulated contacts 1, 2, 3, 4, &c. 101, 102, 103, 104 &c. and a, b, c, &c., a, #, &c. on stationary discs 34, 134.

Abstract: 1323987 Crisp-frying PROCTER & GAMBLE CO 5 May 1972 [15 Nov 1971] 21040/72 Heading A4D [Also in Division B8] A method for the prevention of dough accumulation due to stuck crisps on a carrier of a crisp frying machine in which raw dough pieces are held between pairs of carrier members for passage through a cooking zone comprises resting for the presence of a stuck crisp on a carrier using electric photo-sensors 23, 25 and transmitting a signal to an electronic shift register 31, controlling the discharge of a high pressure jet of fluid medium from a nozzle to remove a stuck crisp, testing for the presence of a stuck crisp beyond the high pressure jet with further photosensors 24, 26 and transmitting a signal to the shift register 31 on sensing a stuck chip and actuating, by means of the shift register, means to prevent a raw and dough piece from being deposited on a carrier holding a stuck crisp. The fluid medium may be frying-oil or steam at a pressure of 1000psi with a nozzle bore of #". The method of preventing dough pieces being deposited on the carrier comprises using a compressed air line 40 to blow the dough piece on to a removal conveyer 42. Alternatively a mechanical stripper may be used. The photo-sensors 23-26 may be replaced by mechanical elements. The crispfrying apparatus with which the method is used is similar to that in Specification 1284283 in which the chip carriers comprise upper carrier members 14 moving on an endless conveyer 10 and lower carrier members 19 on an endless conveyer 15.

Moulding celluloid. - In the manufacture of shaped objects from cellulose derivatives of naphthenic acid and of the higher fatty acids, the material is subjected to a preliminary rolling treatment. For example, cellulose trilaurate is rolled between two rollers for 30 minutes at a temperature of 60-70‹ C., the material being twisted and turned several times during the operation. The invention is applicable to derivatives of saturated or unsaturated, substituted or non-substituted higher fatty acids containing more than 8 carbon atoms, e.g. cellulose laurate, ethyl cellulose palmitate, cellulose aceta-stearate, cellulose butyro-ricinoleate or cellulose naphthenate. Pigments, dyes or filling materials may be incorporated during the rolling treatment.

Title: Heat exchanger elements
IPC: F22B37/70
Filed: 1962-06-01
Abstract: 967,022. Forced flow steam boilers; feed-water regulation; steam superheaters. SULZER FRERES S.A. June 1, 1962 [June 9, 1961], No. 21247/62. Heading F4A. A heat-exchange element, particularly for a forced flow, once through steam generator, operating at subcritical or super-critical pressure, comprises two or more tubes 5 extending in parallel between headers 2, 10 the tubes 5 being subdivided over at least part of their length by tubes 6 extending from a header 4 but discharging in common with the annular passages 13 of the tubes 5 into the header 10. The medium to be heated flows from a pipe 11 into a fork pipe 9, one of the branches of which contains a control valve 3, and thus into the headers 2, 4 to flow in parallel through the pipes 6 and passages 13. By means of the valve 3 the flow to the pipes 6 can be controlled independently of the flow to the passages 13 and thus instability of flow in these passages avoided, for example at partial load on a steam generator. As shown in Fig. 3, the element may form the conversion zone of a forced flow once through steam generator. The valve 3 regulating the supply of feedwater from a turbine driven pump 18, 34 to the inner pipes 6 is controlled by a servomotor 38 in dependence upon the pressure differential between the steam outlet pressure and a desired value input obtained from the pressure control elements 47, 50. A fuel supply control valve 44 is regulated in conjunction with the valve 3 by means of an arm 42 and control rod 43. Total feedwater supply is controlled by varying the steam supply through line 33 to the turbine 34 and control is effected by means of a temperature pick-off 36 and valve 35. In a simplified form (Fig. 2, not shown), the valve 3 is regulated by the pressure drop through the steam generating zone. In a modification the branch pipes of the fork pipe 9 form an economizer in the convection section of the steam generator, Fig. 4 (not shown). The invention may also be applied to a superheater in which case the internal pipe is preferably fitted at the outlet end of each superheater tube, Fig. 17 (not shown). The subdivision of the pipe 5 may be effected by a variety of partitions and of differently shaped tubes to give two or more internal passages Figs. 8-14 (not shown). Where the element has pipes 5 with more than two passages separate control valves may be provided for each passage, Fig. 15 (not shown). The control valve is preferably fitted to the passage or passages which are not the most intensely heated.

Abstract: 989,363. Hydraulic reciprocating motors. A. FRASER. May 28, 1963 [March 20, 1962], No. 21303/63. Divided out of 989,362. Heading F1A. In an hydraulic, radial cylinder motor comprising pistons 1 engaging an eccentric 5 and reciprocating in cylinders 2 each supplied from a high pressure ring main 9 via an inlet valve 7 and exhausting into a low pressure ring main 13 via an exhaust valve 19, the inlet valve 7 is timed to open after the piston has begun its downward stroke and the cylinder is connected to the low pressure ring main via a check valve 15 until inlet valve 7 opens, thereby increasing the total volume of liquid passing through the motor, and hence the motor speed, without increasing the rate at which high pressure liquid is supplied to the motor. A further increase in speed is obtained by timing the exhaust valve 19 to close before the piston 1 reaches the end of its exhaust stroke, e.g. 5 or 10 degrees before T.D.C., the high pressure developed being exhausted into high pressure ring main 9 via a check valve 24. The increase in speed will depend on how late in the working stroke of each piston the inlet valve 7 is opened, this timing being adjustable. The valve timing is arranged so that the pistons being moved on their driving strokes always act with a greater moment than the pistons exhausting into the high pressure main.
