Patent GB-896551-A (GB)
Title: Improvements in inverter circuits
Inventor: EASTOP ROBERT HENRY
IPC: H02M3/338
Filed: 1959-01-06
Abstract: 896,551. Inverting. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Jan. 5, 1960 [Jan. 6, 1959], No. 516/59. Class 38 (2). [Also in Group XL (c)] An inverter circuit comprising four switching devices arranged in a bridge configuration so that pairs of opposite arms can be rendered conducting alternately, is characterized in that each load terminal is connected to the junction between respective pairs of unidirectional conducting devices so as to provide paths for excess voltage which tend to occur between switching off one pair of switching devices and switching on the other pair. Four transistors 1, 2, 3, 4 are connected in a bridge circuit having a winding 12 of a transformer 5 connected between the junction of transistors 1, 3 and the junction of transistors 2, 4. Windings 14 are connected between the base and emitter of each transistor such that when transistors 1, 3 are conductive transistors 2, 4 are non-conductive and vice versa. In order to ensure starting the circuit is made assymetrical by the inclusion of resistors 17, 17a. For limiting overshoot when none of the transistors is conductive diodes 18, 19 are provided to prevent the potential across the winding 12 from exceeding a predetermined maximum voltage. A combination of PNP and NPN transistors may be used and the circuit may be separately excited instead of selfexcited.

Title: Improvements in or relating to apparatus for testing combustible gas
Inventor: OLLET WILLIAM JOHN
IPC: G01N25/54
Filed: 1956-01-06
Abstract: The approach to explosibility of a combustible gas such as occurs in the gas-manufacturing and coke-oven industries in which it is convenient to use an electrostatic precipitator for the removal of tar from the gas, is tested in an apparatus comprising a proportional pumping device for delivering the combustible gas and a predetermined portion of added air intermittently to an explosion chamber, electrical means controlled by the ignition device which develops a steady control voltage when the ignition device is in operation, an electronic relay to which the control voltage is applied, and a safety switch which is operated by the electronic relay upon failure of the ignition voltage.  Optionally the safety switch may be also arranged to switch off an electrostatic separator.  The application is an improvement in the apparatus of parent Specification, which eliminates the possibility of explosion in the electro-detarrer when a failure occurs in the ignition voltage of a testing apparatus.

Filed: 1967-01-05
Abstract: 1,196,161. Pipe couplings. R. C. NEWLAND (ENG.) Ltd. 5 April, 1968 [5 Jan., 1967], No. 744/67. Heading F2G. An electrically insulated coupling for Combustible materials comprises an electrically insulating sealing element 9 having a thickness not exceeding À010 inch clamped between end faces of coupling members 5, 6 and fastening means 13 engaging and interconnecting both the members and insulated from one of the members.

Patent GB-1279026-A (GB)
Title: Digital control system
IPC: H03L7/06
Filed: 1970-01-07
Abstract: 1279026 Phase lock INTERNATIONAL BUSINESS MACHINES CORP 7 Jan 1970 [15 Jan 1969] 757/70 Heading G4H A phase locking system in which the output phase, and frequency of a series of pulses is looked to the phase and frequency of the input by means of a digital control loop, comprises a binary counter 52 with a capacity of 63 counts. The point at which counting starts and stops can be varied, when the count reaches 32 an output pulse is produced. A string of pulses at a frequency very much greater than the input frequency on line 58, is produced by oscillator 50, and fed into counter 52. AND gates 62 and 66 are enabled when input pulses arrive and when the count is less than 32, (66), or greater than 32, (62). Thus the count measured by error counter 74 represents the time deviation of the output pulse from the input pulse. The error counter is counted down to zero by oscillator 50 via latch 80 and AND gate 82. The pulses are counted by sealers 70 and 72 depending on whether the count is positive or negative. The counter selected to count is determined by AND gates 68 and 64. The sealers can produce an output via AND gates 88, 90 and OR gates 92, when a number of pulses have been recorded, these output pulses determine the count value at which the cycle restarts, i.e. at which counter 52 stops and resets itself. In this way a phase correction is produced. Outputs from scalers 70, 72 are also fed via frequency integrator 54, into reference counter 52 to determine the count value at which the count commences, thus producing a frequency correction. The feed back loops is thus of the 2nd order. In a second embodiment, the error counter 24 is replaced by, full adder 102, Fig. 4, error register 106, threshold decode logic 108 which supply phase correction pulses on lines 110 and 112, these pulses trigger registers 114 and 116 which add preset constants into full adder 102. The output from the threshold logic 108 is also fed to frequency integrator 118 which supplies a frequency correction pulse. In a third embodiment frequency correction is provided by modifying the frequency of oscillator 50.

Abstract: 785,411. Fuel injectors. SAURER, Ltd., A. Jan. 10, 1956 [Feb 23, 1955], No. 796/56. Class 7(3) A fuel injection valve 3, Fig. 3, lifts a small distance against a first spring 6 to give a low-pressure pre-injection, whereupon the valve becomes loaded by a stronger spring 5 which does not yield until the fuel pressure has risen to that required for the main injection, the spring 6 being located between two movable abutments, 11, 8, associated respectively with the valve 3 and the spring 5. In Fig. 3 the spring 5 acts upon a disc 8 which is abutted by the upper end of the valve 3 after it has risen a small amount for the pre-injection. In a modification the end of the valve 3 is provided with a pintle and in Fig. 5 the valve 30 opens outwardly and opens first against a weak spring 28 until an abutment 29 contacts a plate 26 loaded by the main spring 27 which yields when the main injection pressure is reached.

Title: Improvements in or relating to the treatment of crude cellulose
IPC: D21C11/00
Filed: 1921-01-07
Abstract: 156,777. Harnist, C. July 6, 1914, [Convention date]. Pulp, preparation of; waste products, treatment and utilization of.-In the preparation of cellulose and a valuable residual lye, raw cellulosic materials are subjected to the action of ammonia or other soluble alkali or alkaline carbonate and sulphurous acid in succession or alternately. The material may be subjected to preliminary steaming with or without the addition of alkaline or organic solvents in order to remove tannin, resins, &c., useless in fermentation or in manures, and the ammonia and sulphur dioxide introduced in gaseous form under pressure, with or without the addition of water. The residual lye is neutralized or rendered alkaline and subjected to oxidation as by hot furnace gases, or subjected to hot waste gases from sulphur or pyrites furnaces, in towers, with or without the admixture of catalysts. Sulphur dioxide is thus eliminated, ammonia and alcohol are carried off, and the concentrated liquor may be subjected to alcoholic fermentation, or used as a manure either alone or admixed with potash salts or other fertilizing-substances. Where the material is first treated with ammonia and the liquid is neutralized with sulphur dioxide, the resins and tannins are precipitated and separated. Specification 5552/11 is referred to. According to the Specification as open to inspection under Sect. 91 (3) (a), waste lyes from the calcium bisulphite method may be similarly treated after first treating them with ammonia. The precipitated tannins and resins may be dissolved in turpentine, benzol, &c., and, with or without preliminary oxidation by calcium hypochlorite or potassium permanganate, may be used for sizing paper. Precipitation of these substances may be assisted by the addition of aluminium sulphite. Where sulphur dioxide is used first, its action is moderated by the addition of sacchariferous substances such as molasses, vinasse, or distillery residue. The process is applicable to substances poor in cellulose such as maize straw, rushes, leaves, &c. This subject-matter does not appear in the Specification as accepted.
