Title: Improvements in and relating to automatic reclosing circuit breaker systems
IPC: H02H3/07
Filed: 1927-12-29
Abstract: 282,811. British Thomson-Houston Co., Ltd., (Assignees of Traver, O. C.). Dec. 30, 1926. [Convention. date]. Cut-out arrangements.-In an automaticallyreclosing circuit-breaker system of the kind in which the circuit-breaker is reclosed automatically a certain number of times and (if the fault persists) is then held out, the interval between tripping and reclosure is made to increase in dependence on the degree of overload. The circuit-breaker 1 connecting two circuits 2, 3 is tripped on overload by the closure of an overload relay 7 which closes a circuit for a trip magnet 6 acting on the latch 5. The overload current also serves to drive practically instantaneously the disc 11 of an induction-ammeter element through an angle dependent on the overload. If the overload is very great the disc is driven so far that a projection 24 thereon engages with a detent 25 and no reclosure takes place. With lesser overloads, however, the disc is free to return under the action of the spring 13 and under the retardation of an induction disc brake 19, the clutch 22 of which slips in the forward movement. After a time which depends upon the angular distance the disc has been moved a pin 17 thereon re-engages with contact-springs 15, 16 and closes the circuit of a relay 9. in series with the contacts 28 of a notching relay 27. The relay 9 completes the reclosing circuit 4 for the circuit-breaker. After the circuit-breaker has been reclosed in this way a predetermined number of times the arm of the notching relay, which is energized by closure of back contacts 29 on the circuit-breaker, moves sufficiently far as to open the contacts 28 and prevent further reclosure.

Filed: 1973-07-26
Abstract: 1430467 Automatic control of machine tools ALLEN-BRADLEY CO 26 July 1973 [31 July 1972] 35612/73 Heading G3N  A machine tool is controlled by a control arrangement including an interface circuit connected to a numerical control system to receive auxiliary command words generated by said N.C. system and from which words state logic signals are generated, a store containing a plurality of storage elements connected to receive and store said state logic signals and a programmable controller connected to selectively address the storage elements and programmed to read the condition of each element whereby to provide a control instruction. In the arrangement shown the programmable logic controller described in Specification 1379181 is modified by the addition of an addressable storage bank which forms a further input circuit and is connected through an interface circuit 15 to a numerical control system 14. The interface circuit 15 comprises a buffer shift register and a read only memory into which the auxiliary command words are read before being de-coded and passed to the addressable storage bank. A flag signal on line 20 is passed from the numerical control through a monostable multi-vibrator in the interface to the addressable storage bank where it is used to control the reading in of the de-coded auxiliary command word. The addressable storage bank 9 consists of a plurality of JK flip-flops, each of which has a set and reset state and has each input connected through an AND gate to the decoder circuit of the interface circuit. These J.K. flip-flops are interrogated by the address de-coder 8 of the controller to obtain auxiliary command information which is then placed as a command instruction in the output circuit 11. In an alternative embodiment Fig. 4 (not shown) an addressable multi-plexer is provided in the interface circuit which reads out the auxiliary command words to the programmable controller to cause it to generate the state logic signal which is then stored in an addressable storage element. In a modification the provision of a separate memory and de-coder circuit in the interface circuit is avoided by providing the controller memory with two portions. The arrangement results from the expanded input/output capacity controller disclosed in Specification 1379941.

Patent GB-955690-A (GB)
Title: A method of producing inosine
IPC: C12P19/40
Filed: 1960-10-19
Abstract: Inosine is produced by culturing under aerobic conditions a mutant strain of the species of the micro-organism Bacillus subtilis in a culture medium containing a carbohydrate and/or a polyhydric alcohol as a carbon source, a nitrogen source, a sufficient amount of a source of adhesive and a source of protein amine acids as nutrient, and a source of potassium, magnesium, ferrous, manganous and phosphate ions, the pH of the culture medium being kept between 4 and 9 and the temperature between 25 and 40 DEG C. Specified carbon sources are glucose, fructose, mannose, cyalactose xylose, arabinose, sucrose, starch hydrolasate, soluble starch, molasses, glycerol, sorbitol, mannitol and ethylene glycol. Mutant strains listed are strains ATCC No. 13,952-13,956.  Nitrogen sources specified are ammonium salts, urea, nitrates and ammonia whilst specified nutrient sources which supply adhesive and a protein amino acid are dry yeast, yeast or meat extract, casein hydrolysate, NZ amine, polyheptone, corn steep liquor and sodium rebonucleate.  Amino acids listed are histidine, aspartic acid, lysine, metheonine, cystine, valine, glycine, tyrosine, leucosine, threonine, tryptophane, proline, arginine, phenyl-alanine serine alanine and glutamic acid. The pH is maintained preferably between 5 and 6.7 by adding ammonia, calcium carbonate, potassium or ordium hydroxide to the culture medium which is aerated preferably by agitation. Inosine is separated from the culture by treating the culture liquid with an anion exchange resin and then with activated charcoal to absorb the inosine.  The absorbed inosine is eluted with ammonia/ethanol/water solution, concentrated and precipitated by adding an inosine-insoluble solvent e.g. acetone.

Title: Printing machine
Inventor: HARRISON HERBERT GEORGE
IPC: B41K3/04
Filed: 1965-08-21
Abstract: 1,122,482. Printing machines. ENGLISH NUMBERING MACHINES Ltd. 15 July, 1966 [21 Aug., 1965], No. 35972/65. Heading B6C. A printing machine, e.g. a machine for printing numbers sequentially, can be set so that it prints on single sheets with a light resilient pressure or so that a greater pressure is applied when a number of sheets with interposed carbons, or relatively thick documents, are to be printed. The typewheels are carried by a plunger rod 20 mounted in a printing head 10 supported by parallel links 11, 12. A pin 22 on the rod 20 engages a slot 24 on a lever 26 fixed to a shaft 28 to which is fixed another lever 51. The lower end of lever 51 has a pin 50 sliding in a slot 49 in a link 47 and connected to the link by a spring 52. The link 47 is pivoted at 88 to a driven disc 61 of a one-revolution clutch 60. The clutch is operated by a member 32, and for printing with light pressure, the link 47 through the spring 52 and levers 51, 26 moves the printing unit 10 downwardly to print. During this operation, one arm 55 of a double-armed lever 55, 58 is engaged by a pin 97 on a manually settable control member 54, so that a recess 59 with a stop-shoulder 98 on the arm 58 is out of range of a projection 53 on the lever 51. If printing with increased pressure is required, the member 54 is rotated by the operator so as to move the pin 97 away from the arm 55 which then moves into a groove in the member 54 under the action of a spring 57, so that the pin 53 now engages the recess 59. If now the clutch is engaged, the lever 51 is rotated as before until the pin 53 engages the shoulder 98 whereupon the link 47 moves independently of the lever 51 and stresses the spring 52. Subsequently, a pin 83 on the clutch disc 61 strikes the tip of arm 58 to pivot the arm downwardly and release the projection 53. The lever 51 is then free to pivot and drives the unit 10 downwardly under the action of the stressed spring 52. During upward movement of the unit, an adjustable stop 94 is engaged by one of the links 12 to limit upward movement of the head 10, but upward movement of the rod 20 continues to bring the typewheels into contact with an ink pad in the head 10. The unit 10 can be swung by means of a handle 33 into a position wherein the typewheels are readily accessible for adjustment. With the operating link 51 stationary, a member 43 associated therewith holds the links 11 stationary. Movement of the handle 33 causes the links 12 to move the unit about its pivot 14 with the links 11, and the slot 24 engaging the pin 22 on the rod 20 causes the typewheels to be projected. At the same time, an arm on the shaft of handle 33 opens a switch in the circuit of a motor driving the clutch 60.
