Title: Motorised valve
IPC: H02K23/66
Filed: 1972-01-14
Abstract: 1363922 Valves ISIS TECHNICAL FINISHES Ltd 9 Oct 1972 [8 Oct 1971 14 Jan 1972 2 May 1972] 46855/71 1800/72 and 20326/72 Heading F2V [Also in Division H2] A rotary ball valve 2 is connected by sleeve coupling 10 and worm-and-wheel gearing 9 to the motor 7 whose windings are short-circuited, when the valve is in its open and closed positions, by a switch 16 operated by cams 17, the short-circuiting serving to produce a braking action. In Fig. 4, the motor is started by energizing solenoid 19 to move switch 18 to establish a power circuit including the motor windings, and when switch 16 has been moved to its other position the switch 18 is returned to the position shown to maintain a supply to the motor until the switch 16 is returned to the position shown in which the motor windings are short-circuited. A further switch 22 may be included to illuminate lamp 21 to indicate when the valve is open. The lamp may alternatively be located in the positive power line between socket 20 and switch 16. The solenoid 19 may be controlled through an R.C. circuit arranged to return switch 18 after a preset period sufficient to allow operation of switch 16 by the first cam to arrive after energization of the motor. Switch 28, 29 allows local manual control. Solenoid 24 is used either to produce a feedback signal indicating successful operation of the valve or to provide automatic reset of the starter switch, as in Fig. 5. By removing one pair of cams, the valve may be arranged to stop only in closed positions, and switch 18 may be held closed to provide a pulsed flow. In such latter case, the valve may deliver a dosing fluid to a liquid to control pH or redox value, and an electrode measuring the latter value may control switch 18 to maintain the value at a desired level. The motor may also serve to reciprocate the electrode through a cleaning bath or to reciprocate a cleaning collar along the electrode. Instead of mounting the motor, valve and selected switches in a two-part casing 15, the parts may be encapsulated, e.g. in foamed polyurethane. The valve may alternatively be multi-way, and the motor may be reversible.

Title: Improvements in or relating to the tenderizing of meat
IPC: A23L13/70
Filed: 1970-01-15
Abstract: 1,243,605. Tenderizing meat. CORNELL RESEARCH FOUNDATION Inc. 15 Jan., 1970 [17 Jan., 1969; 24 Feb., 1969], No. 2107/70. Heading A2U. Selected edible muscle in the carcase of a freshly slaughtered meat animal is tenderized by the application of sufficient tension to extend the muscle prior to the onset, and during and through the completion of rigor mortis. In one method, applicable to beef carcases which are split longitudinally and each half suspended by the rear leg, extension of the back muscle is achieved by severing the backbone at several locations 2, 4, 6, 8, 10, Fig. 1. To increase the tension due to the weight of the half carcase an additional weight 40 may be hung from the neck region. Other bones are severed at locations 12, 14, 16 tension the corresponding muscle, and in the case of the location 16 the fore leg may be tensioned by an additional weight. Bones are severed at similar locations in pork and lamb carcases, although in the case of pork the preliminary step of removing the fat cover is necessary, and with lamb, which is not split longitudinally, the backbone must be severed by a tool such as a sharp chisel, pruning shears, etc., instead of by sawing as is possible with carcase halves. An alternative method of applying tension to the selected muscles involves the use of a tool such as that illustrated in Fig. 10 comprising two members 52 each fitted with a row of pins 50 for insertion into the muscle to be tensioned and a lever system 56 for extending the tool which is locked in the extended condition by means 54. The use of such a tool converts an adverse articulation of the bone joints to a beneficial articulation in which the muscles are extended. The backbone and rear leg bones in a lamb carcase may be flexed to extend the back and rear leg muscles by suspending the carcase from a hook situated anterior to the pelvic bone.

Filed: 1960-01-25
Abstract: 885,554. Coin-freed apparatus. UNITED MUSIC CORPORATION. Jan. 25, 1960, No. 2686/60. Class 27. A coin totalizer for a coin-freed machine, such as a gramophone, comprises a toothed rotor 2 movable by a spring 13 in the credit direction, pawls 4a, 5a, 6a selectively operated by electromagnets 4, 5, 6 for releasing the rotor for rotation through angles corresponding to the value of coins inserted and a pawl 18 operated by an electromagnet 9 for restoring the rotor to its initial position on receiving one or more pulses from the operated machine. The magnets 4, 5, 6 are operated by the closing of switches 48, 49, 50 by the inserted coins and the pawls 4a, 5a, 6a overlap so that only pawl 6 is withdrawn when magnet 6 is operated, both pawls 5 and 6 are withdrawn when magnet 5 is operated and all three pawls are withdrawn when magnet 4 is operated. Magnets 5 and 6 may be arranged to be energized together when two coins of the lowest denomination are inserted. Accordingly, the rotor is released to rotate only one step, until a long tooth 36 engages pawl 5, three steps, until a longer tooth 37 engages pawl 4 or a larger number of steps, according to the selected lateral position of a threaded stop 22 which is engaged by one of several offset stops 23-27 on the rotor. On movement of the rotor, a projection 32 moves from under an arm of a switch 11 to energize a coil 52 that operates, or conditions for operation, the machine and de-energizes a coil 51 for rejecting coins inserted during operation of the machine. When one or more selections are made in the machine by a lever 65, switch 54 energizes the coil 9 so that pawl 18 operates one or more times to act on teeth 17 and restore the rotor to its original position. Each operation of pawl 18 closes a switch 42 so that a counter 55 counts the number of debit operations. Where only one closure of switch 54 is possible in the machine, a switch 43 can be connected into the circuit so that, while the switch 54 is closed, the coil 9 continues to be intermittently energized until the rotor is restored to its original position.

Abstract: 305,661. I. G. Farbenindustrie Akt.- Ges. Feb. 10, 1928, [Convention date]. Carbohydrate esters.- Higher fatty acid and cyclocarboxylic acid esters of starch and like carbohydrates, which esters are soluble in organic solvents, are obtained by causing the polymerized carbohydrate to swell in alkali hydroxide of at least 30 per cent strength and then permitting the reaction with the halide of the higher fatty acid or of the cyclocarboxylic acid to take place with rise of temperature, heat being applied if desired. The fatty acid halide may be derived from a saturated or unsaturated, substituted or unsubstituted fatty acid containing more than five carbon atoms; suitable halides of cyclocarboxylic acids are cyclopentane and cyclohexane carboxvlic acid chlorides. The esters obtained are soluble in organic solvents, are colourless, and the cyclohexane carboxylic acid esters, although very hard at normal temperatures, are capable of being moulded at 50‹ C. without the aid of a solvent or softening agent. The esterification may be carried out in the presence of an indifferent diluent. In examples, rice starch is treated with 40 per cent caustic soda solution, and then suspended in a mixture of benzene and benzoyl and lauric chlorides, the reaction mixture being allowed to boil gently; powdered agaragar is swollen with 40 per cent caustic soda solution, and to the mixture is added the mixed chlorides of cocoanut oil fatty acids, while allowing the temperature to rise due to the heat of reaction; starch, caustic soda and water are stirred together to produce a gelatinous mass which is introduced into a mixture of phenylacetic acid chloride and benzene, maintained in a state of gentle ebullition by the heat of the reaction. The products obtained are suitable for the manufacture of threads, films, lacquers. coating and insulating compositions, and plastic masses; and they may be moulded by the process described in Specification 289,063, [Class 2 (ii), Cellulose &c.].
