Patent GB-792282-A (GB)
Title: Improvements in and relating to linear-dimension gauges
IPC: B07C5/08
Filed: 1956-04-09
Abstract: 792,282. Gauging-and-sorting apparatus. WINTLE, H. D., and STROM, G. E. April 9, 1956 [April 13, 1955], No. 10773/56. Class 106 (2). A gauge for classifying by length elements 3 produced by a machine having a rotating shaft 4 comprises an arm 7 coupled to the shaft 4 so as to oscillate in response to rotation of the shaft 4, causing a pair of fingers 20, 21 mounted on the arm 7 to sweep across one end of a machined element 3, one finger 20 extending from the arm 7 a greater distance towards the element 3 than the other finger 21 and each finger 20, 21 coupled to an electric circuit, the circuits being operative in response to contact between the element and fingers and means including the circuits for physically displacing the element when contact is made, whereby classification is determined according to whether one, both or neither finger contacts the element. In a machine for coiling one spring 3 for each revolution of the shaft 4 the arm 7 is pivoted on a journal 12 in a plate 13 and is reciprocated through a slot 11 engaging an adjustable eccentric pin 8 on an adapter 5 adjustably secured to the shaft 4. Fingers 20, 21 are individually adjustable on a block 24 in accordance with the degree of tolerance permissible and the block 24 is adjustable in a member 34 in accordance with the desired length of the spring 3. In each revolution of shaft 4 a spring 3 is coiled at the point 2 and about 120 degrees before the end of each revolution switches 39, 40, operated by a cam 43, adjustable on the adapter 5, close to prepare (1) a circuit through a solenoid 72 operating an air valve for displacing bad springs and (2) circuits through thyratrons 48, 49 in circuit with the fingers 20, 21, respectively. Thereafter the fingers sweep past the spring and when a good spring is gauged it contacts only finger 20 which causes the thyratron 48 to fire, if the spring is too long it contacts both fingers 20, 21 and thyratron 49 also fires, if the spring is too short it contacts neither finger 20 nor finger 21 and neither thyratron 48 nor 49 fires. Further thyratrons 70, 71 in the circuit of the solenoid 72 react according to the states of the thyratrons 48, 49; thus 70 fires if neither 48 nor 49 fires, indicating a short spring, and 71 fires if 49 fires, indicating a long spring, and in either case the solenoid 72 is energized and the spring is blown aside. If 48 fires, indicating a good spring, neither 70 nor 71 fires, solenoid 72 is inactive and the spring falls into a hopper. At the end of the revolution the switches 39, 40 open to clear the storage thyratrons 48, 49 and open the solenoid 72 circuit. The whole gauge may be adjusted with respect to the machine end-plate 1 by rotating the plate 13 about the shaft 4 and the switches 39, 40 and journal 12 are enclosed in a housing 46.

Filed: 1962-03-23
Abstract: 992, 034. Automatic speed control. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 23, 1962, No. 11257/62. Heading G3R. [Also in Division H2] The armature 1 of an electric motor is supplied through reversing switch 2 from converter 3 having grid control unit 7. A comparator 6 is supplied with reference and speed-responsive voltages the error signal being applied to unit 7 for speed control of the motor. Forward and reverse solenoids 10, 11, are energized from circuit 9 which is operated in dependence upon signals from the comparator 6. A current-detector coil 12 is adapted to prevent operation of the switch 2 while the motor is being supplied with current. However, under fault conditions, the switch 2 could be operated while it is traversed by current sufficient to damage the switch contacts. To avoid this, the solenoids 10, 11 are associated with auxiliary relays 13, 14, having contacts 13<SP>1</SP>, 14<SP>1</SP>. When the reversing switch is in its forward position, the solenoid 10 is energized, solenoid 11 is de-energized, and contact S is open so that relay 13 is not energized. Thus contacts 131, 141, remain closed. When the reversing switch is to be changed-over, relay 14 becomes energized, the reversing switch not changing its state until the voltage across solenoid 11 reaches a predetermined value so that contact S1 remains closed. Relay 14 opens contact 14<SP>1</SP> in circuit with unit 7 so causing maximum firing delay, the converter operating as an inverter and preventing the flow of armature current until the reversing switch has completed its movement.

Abstract: 932,337. Electrolytic recovery of chlorine from brines. OLIN MATHIESON CHEMICAL CORPORATION. March 23, 1962, No. 11264/62. Class 41. Chlorine produced by the electrolysis of an aqueous brine of an alkali metal chloride, wherein the chlorine is cooled, dried and compressed to obtain liquid chlorine and a " blowoff gas " containing nitrogen and oxygen as air and non-condensed chlorine, said gas being washed with alkaline brine of pH over 9.5 to absorb the chlorine until the pH is reduced to below 6 and then recycling the brine for electrolysis. The brine is usually a sodium chloride brine. The alkaline brine is obtained from cells of the diaphragm or mercury type. The weak and spent brine effluent saturated with chlorine from cells of the mercury type is dechlorinated by vacuum and then by aeration the liquor then being resaturated by contact with salt. Alkali as caustic soda or soda ash then purifies the solution of contaminants in the salt by precipitation and separation: the alkaline brine produced ordinarily has a pH over 9.5 and is suitable for treating blow-off gas. Cells of the diaphragm type yield an effluent containing non-consumed salt plus the caustic product which is treated by crystallisation to precipitate the salt, said salt then being washed to remove much of the caustic liquor: on solution of the salt a brine ordinarily of pH over 9.5 is formed. The " blow-off " gas from the liquefaction of chlorine is treated to recover the chlorine.

Abstract: 657,536. Checking shuttles and picking sticks hydraulically. WEATHERHEAD CO. April 30, 1947, No. 11571. Convention date, May 16, 1946. [Class 142(iii)] [Also in Group XXXII] After a picking stroke, the picking stick (not shown) is retracted by its return spring until a spring 17, coupled to the stick by a link 15, balances the return spring to bring the stick to rest before it is fully retracted; meanwhile a piston P has displaced liquid freely from a cylinder C to a reservoir R through holes 28 in the cylinder wall and a hole 45 in the piston. When the shuttle strikes the picking stick, the piston is pushed further into the cylinder, .closing the holes 28, so that all the displaced liquid passes through the hole 45 which is progressively closed by a metering pin 43, thereby arresting the shuttle smoothly. On the picking stroke, a non- return valve 36 opens to allow the cylinder to refill freely; the final part of the stroke is cushioned by a spigot 51 on the piston entering a hole 52 between the cylinder and the reservoir. A similar construction described has the metering pin on the piston, and another also has the non-return valve in the piston.
