Title: Improvements in or relating to mine signalling systems or the like in which the signals consist of a single series of impulses
IPC: B66B19/06
Filed: 1921-11-15
Abstract: 193,361. Automatic Telephone Manufacturing Co.. Ltd., and Remington, C. Nov. 15, 1921. Order apparatus ; mine signalling systems.-In systems in which, if the " men " signal is sent during the wind and a subsequent action signal is deferred until the engine has come to rest, the " men " signal is not cancelled until the end of the next wind, the " men " signal is maintained by either of two devices, one of which is released by the transmission of the next signal, and the other by the coming to rest of the engine. The men signal is controlled by a relay 13 which is first energized by the transmission of the " men " signal and subsequently in a locking circuit independent of the first circuit, the locking circuit being broken at the end of the wind, and the first circuit on the transmission of another signal or at the beginning of the wind. The system described is identical with that described in Specification 193,128. Supposing the onsetter at A has sent the signal on his key TK to " raise " " men." The lamp 3 will be maintained alight by relay 13 which, after being once energized in a circuit including wiper 34 and the 3rd bank contact, is locked up in an independent circuit, including contact 40 of slow-acting relay 16. When the engine starts, relay 17 energizes, completes a circuit for relay 16, and opens at 36 the locking circuit of a relay 12 so as to cancel the action signal. This circuit is immediately re-made by relay 16 at contact 45. Relay 17 completes at contact 46 the locking circuit for relay 13 before it is broken at contact 40, but when the engine stops the locking circuit is broken at contact 46 before it is made at contact 40, so that the "men" signal is cancelled. If, however, the " men " signal is sent during the wind, relay 12 locks up and on the stopping of the engine, relay 13 is maintained energized over wiper 34, the 3rd bank contact and a contact of relay 12, the circuit of which is made at 36 before it is broken at 45. On the following action signal, wiper 34 leaves the 3rd contact, but relay 13 remains energized by its independent locking circuit, so that the " men " signal stays alight until the end of the next wind. The Provisional Specification describes further details which form the subjectmatter of Specification 193,128.

Title: Spray guns and the like
Inventor: EDWARDS HARRY
IPC: B29B7/74
Filed: 1960-01-21
Abstract: 913,611. Spray-producers. IMPERIAL CHEMICAL INDUSTRIES Ltd. Jan. 6, 1961 [Jan. 21, 1960], No. 2241/60. Class 69 (3). A gun 1 for generating and spraying polyurethane foams has a mixing chamber 22 for the foam-producing ingredients provided with a number of inlets 21 and an outlet 24, and each ingredient is fed to an inlet via a non-return valve 10. An inert gas, e.g. air, fed to the gun at 17 flows to the downstream side of each valve through a passage 19 and to an annular chamber 16 to mix with the ingredient, and the mixture flows through an inlet 21 to the mixing chamber. Each ingredient is fed to its valve through a channel 3 in an elbow 2 fastened to the gun by a pivoted clamp 5; the elbow slides over the hollow stem of the valve which is sealed by a rubber gasket 11 and a rubber sleeve 13. Slots 15 connect with the central passage of the valve stem through which the ingredient flows, and the latter, in passing through the slots, expands the rubber sleeve and squirts into the chamber 16. An air cap 26 may be attached to the outlet 24, and air is supplied from the channel 17 and via a line 34, in which a needle valve may be mounted, to an annular space 35 feeding a number of outlet channels 36. Handles 28, 29 support switches 30 controlling ingredient supply pumps and the air supply. The automatic closure of the valves under back pressure reduces blockages, and a flow of air alone cleans the gun passages. Specification 856,191 is referred to.

Title: Means for correcting non-uniformity in tires
IPC: G01M1/34
Filed: 1968-01-16
Abstract: 1,220,361. Grinding tyres. GENERAL TIRE & RUBBER CO. 16 Jan., 1968 [1 Feb., 1967], No. 2273/68. Heading B3D. [Also in Divisions B4-B5] A tyre 9 is tested and corrected for non- uniformity by determining the amounts and locations of irregularities and controlling the amount and location of the rubber removed from the tyre so as to diminish or annul the irregularities. As shown, an inflated tyre 9 is rotated against a test drum 7 with a predetermined radial load applied by hydraulic pressure. During rotation of the tyre, the radial force variations are measured by the test drum and recorded on an oscillogram 5 of a read-out device, the curve of the oscillogram being reproduced on cardboard 25 which is wrapped around a cylinder 19 rotatable at the same speed as the tyre. A sensing arm 27 follows the curve and a transducer 29 feeds the signal into a control mechanism for a pair of grinding wheels 31 made of steel and coated with tungsten carbide. The set-up of the cardboard on the drum is such as to allow for the time delay between when a portion of the tyre transmits an impulse to the test drum and when the same portion reaches the grinding wheels. Each grinding wheel is adjustably-mounted on a carrier plate (47), Figs. 2 and 3 (not shown), and is moved vertically into and out of engagement with the tyre by an hydraulic cylinder (53), the travel being controlled by the transducer 29 and checked by a transducer (81) in contact with the carrier plate. A further transducer (87) measures the eccentricity or radial run-out of the tyre and delivers a signal to a central mechanism of an hydraulic cylinder (65) for maintaining a fixed distance between the tyre and a mounting plate (54) for the grinding wheel carrier plate. The irregularities may be ground off by repeating the process until the tyres are reduced to an acceptable level, a separate piece of cardboard being prepared for the cylinder 19 at each stage; alternatively, the irregularities may be ground off on a continuous basis, the cardboard being replaced by a cylinder carrying a flexible strip (93), Fig. 4 (not shown), which is moved as the cylinder rotates by a servo mechanism (95) in accordance with the pattern of the radial force variations, a transducer (97) being provided to follow the curve of the flexible strip and send a signal to the control for the grinding wheels. A comparitor may be used to automatically terminate the process when the radial force variations are within an acceptable range or are too large to be easily corrected. If desired, the driving motor for the tyre, and optionally a brake, may be controlled so as to temporarily halt rotation when grinding is to take place. Grinding wheels of different coarseness may be employed to provide a polished finish and each grinding wheel may be separately controlled if so desired. Instead of using an oscillograph, the measurements from the test drum may be recorded by a memory device such as a tape recorder.

Title: Digital data storage circuit
IPC: H03M1/00
Filed: 1957-01-22
Abstract: 798,057. Data-storing apparatus; digital electric calculating-apparatus. SPERRY RAND CORPORATION. Jan. 22, 1957 [Jan. 23, 1956], No. 2286/57. Class 106 (1). An electric circuit for storing a serial pulse coded binary word signal comprises bi-stable elements 22, 24, 26, Fig. 1, controlled by output pulses from AND circuits 12, 14, 16 which receive the binary word signal on one input and are successively pulsed in turn at their other inputs, at the repetition rate of the binary word pulses, from a commutator 18 or equivalent means, each bi-stable element except the first receiving a resetting pulse during the pulsing period of the previous AND circuit. As described, the binary signal is obtained from the output of a device 10, e.g. a digital computer, and is preceded by a long start pulse which actuates initiation circuits 20, 28 to start a cycle of the commutator and clear the first bi-stable element 22 respectively. The succeeding elements are cleared by the commutator outputs, the first output clearing the second element and so on. The parallel digital outputs from elements 22, 24, 26 are converted in circuit 30 into an analogue voltage which may be read on a meter 102, Fig. 2. In the circuit shown in Fig. 2, the elements comprise latch-type relays having setting coils 46, 48, 50 and clearing coils 52, 54, 56. The long start pulse from 10 energizes 52 through integrating circuit 58 and energizes relay 74 through monostable multivibrator delay 78 and gate 76. Contacts of relay 74 cause clutch 68 to be energized and to rotate arm 64 of the commutator so as to supply negative potential via segments 60 successively via coils 54, 56 and current limiting resistor 58 to the setting coils resistor 44 and earth. With triode 34 in the normal non-conductive condition, the setting coils are shunted by diodes 86, 88, 90 in series with resistor 36. Thus, only if the triode is rendered conductive by a " 1 "- representing positive pulse from 10, thus reducing its anode potential and blocking the diodes, does the setting coil corresponding to the pulse position receive enough current to energize the relay. The relays control contacts 106, 108, 110 in a voltage-divider digital-to-analogue converter 30 of known type. At the end of the commutator cycle, clear relay 77 is energized to release relay 74 and de-energize clutch 68, the rotary arm 64 being returned by spring 65. An electronic commutator may be used.

Abstract: 524,321. Beryllium compounds. I.G. FARBENINDUSTRIE AKT.-GES. Jan. 24, 1939, No. 2499. Convention date, April 5, 1938. [Class 1 (iii)] Solutions containing beryllium in the form of fluorine compounds are treated, e.g., at 50‹C., with an alkaline earth (including magnesium) hydroxide, and the beryllium is separated from the mixed precipitate (a) by treatment with a solution of caustic alkali or of an alkali metal or ammonium carbonate, filtering, and boiling the filtrate to precipitate beryllium hydroxide or basic beryllium carbonate, or (b) by calcining the precipitate, e.g., to 500-700‹C. to convert the beryllium hydroxide into oxide and chlorinating at an elevated temperature in the presence of carbon to volatilize beryllium chloride. In examples, the beryllium solutions treated are obtained from the decomposition of beryllium ores with sodium silico-fluoride; calcium hydroxide is added to the solutions and the suspensions treated with carbon dioxide to convert any caustic soda formed into sodium bicarbonate; ammonium carbonate is then added, the solution filtered and the filtrate boiled to precipitate basic beryllium carbonate.
