Title: Variable voltage devices
IPC: H01F29/02
Filed: 1975-02-24
Abstract: 1485903 Transformers L LEGNAIOLI 24 Feb 1975 [11 March 1974] 7575/75 Heading HIT A star-connected three-phase variable voltage transformer comprises a magnetic core having three limbs X, Y, Z, each having similar windings and associated switches those for limb X being described here. The secondary windings are divided into two similar sets X 1  to X 4 , X 1 <SP>1</SP> to X 4 <SP>1</SP>, the numbers of turns on the windings in each set being in the ratio 1 : 2 : 4 : 8, and switches I-IV, I<SP>1</SP>-IV<SP>1</SP> are provided to switch in selected windings to vary the output voltage of each set in steps of 1/15 th of the maximum, steps of 1/30 th of the maximum being obtained at P A  by averaging the output of the two sets. Fig. 4 shows a circuit for controlling the switching to increase or decrease the output voltage at P A  at a predetermined rate controlled by a multivibrator clock pulse generator 75 which feeds binary counters 65, 67, the pulses to counter 65 being delayed by half a cycle relative to those supplied to counter 67. With switches 51 and 53 open the circuit applies a binary "1" signal to 65, 67 via 69, 71 to inhibit counting; closing 51 or 53 applies a binary "0" via 69 or 71 to cause the counters 65 and 67 to count up or down to operate the switches (shown at 77) in a predetermined sequence to increase or decrease the output voltage respectively, until the voltage reaches its maximum value or falls to zero when NAND gate 59 or 61 will operate to suppress the binary "0" signal to the counters 65, 67 to inhibit further switching. In an alternative embodiment each set of windings includes at least one winding which is permanently in circuit. The fineness of adjustment can be increased by increasing the number of windings to each set. In a further embodiment (Fig. 5, not shown) the transformer T A  giving the output P A  is replaced by a transformer TaS with two input windings A A , A B  fed by X 1 -X 4  and X 1 <SP>1</SP>-X 4 <SP>1</SP> respectively and an output winding Ac.

Filed: 1967-02-22
Abstract: 1,161,453. Battery testing. ATLANTIC RESEARCH CORP. Feb.22, 1967, No. 8341/67. Heading G1U. The useful life of a battery 10 is indicated on a meter 24 which measures the collecter emitter voltage of a transistor 12 forming part of a voltage regulator circuit connected between the battery and its load 11. While the battery voltage exceeds the breakdown voltage of a Zener diode 22 in the voltage regulator the collecter emitter voltage of the transistor 12 is the difference between the battery voltage and the Zener breakdown voltage, this difference being read on the meter 24 calibrated in hours. When the battery voltage falls below the Zener breakdown voltage the Zener stops conducting, the transistor 12 conducts heavily, the collecter emitter voltage falls to a very low value and the meter indicates that the battery has reached the end of its useful life.

Abstract: 851,361. Abrasive blasting. ASHWORTH, N. I. March 13, 1958 [March 14, 1957], No. 8395/57. Class 60. Articles are polished or ground by placing them, together with members serving to cushion the impact of the articles on one another, in a barrel, and subjecting the articles to a blast of abrasive particles while rotating the barrel. The barrel 1 rotates at about 2-4 r.p.m. in a cabinet 5. The barrel is lined with rubber or other abrasive-resisting cushioning material 4a and has perforations 6. A blast of abrasive particles is projected from a gun 2 mounted on a support 2a passing through an opening 1a in the end of the barrel. The abrasive particles mixed in a body of water may be supplied under sufficient pressure to the gun to produce the blast or a mixture of abrasive particles and water may be ejected from the gun by air under pressure. More than one gun ray be provided and may be given a reciprocating or other movement in the barrel. The barrel has a removable cover 10. Treated articles 3 are discharged via a perforated shoot 7. The water-abrasive mixture passes through the perforations in the drum and shoot 7 to a shoot 8 and to a pump 9 which returns it to the gun. The cushioning members 4 may be of abrasiveresistant rubber which may include abrasive particles to provide a non-slip surface and to assist the polishing or grinding action. Alternatively the members 4 may be of aluminous oxide. They may be bells, polyhedral or other shapes and may have interior weights.

Convention date, April 17, 1931. [Class 92 (ii).] Relates to firing mechanism for recoil-operated automatic guns in which a sear 11 carried by the sliding breech-bolt 5 is moved to release the firing pin by the front end 14a of a triggerlever 14 when the breech-bolt reaches its forward position, as described for example in Specifications 133,351 and 219,932, [both in Class 92 (ii), Ordnance &c.]. According to the present invention, an additional member 18 is provided for automatically holding the breech-bolt in its rearward position, when firing is discontinued, to prevent a live cartridge being left in the barrel. In the cohstruction shown, the member 18 is in the form of a gravity-actuated pawl pivoted at 19 to a spring- controlled rod 23 which absorbs the shock when the pawl engages a notch 20 in the breechblock. When the trigger 16 is operated for continuous fire, the pawl 18 is lifted by the rear end of the trigger-lever the front end of which is then in the path of the sear to effect firing when the breech is closed.

Title: Improvements in and relating to sulphur recovery
Inventor: MILNER GEOFFREY
IPC: C01B17/04
Filed: 1951-04-12
Abstract: <PICT:0716244/III/1> In a process for the production of sulphur by partial combustion of hydrogen sulphide the mixture of hydrogen sulphide and sulphur dioxide thereby produced being passed through a plurality of stages of catalytic conversion and the reaction products from each stage of the conversion being treated for the recovery of sulphur, the concentration of hydrogen sulphide is increased before any stage of catalytic conversion by recycling hydrogen sulphide recovered from the waste gases so that the molecular ratio of hydrogen sulphide to sulphur dioxide is greater than 2.  The concentration is preferably increased immediately before the final catalytic stage.  Residual amounts of sulphur dioxide are removed from the gases leaving the final catalytic stage by washing with water in a lime-stone packed tower, and the hydrogen sulphide remaining is recovered by absorption in a medium from which it may be regenerated for recycling.  The amount of regenerated hydrogen sulphide is preferably between 10 and 20 per cent. of the total hydrogen sulphide fed.  In the drawings, hydrogen sulphide passes through flow controller 1 which diverts one-third of the stream to a combustion apparatus 3 to which air is also supplied to oxidize all the hydrogen sulphide to sulphur dioxide.  The combustion products are mixed with the undiverted stream of gas and enter the first catalyst stage 4 at a temperature of about 600 DEG F.  The mixture leaving the converter is cooled in heat exchanger 5 to a temperature just above its dew point by heat exchange with the gas mixture to be admitted to the second stage catalytic converter 7.  The sulphur vapour is then removed by scrubbing with molten sulphur in the scrubber 6, the exit gas from which, together with hydrogen sulphide recovered from the tail gases by scrubbing with aqueous organic amine solution and regeneration therefrom, are passed to the heat exchanger 5 and heated therein to about 550 DEG F. before admission to the second converter 7.  The sulphur vapour from the gases leaving converter 7 is removed by washing with liquid sulphur in a scrubber 8 and the mixture is passed to an absorber 9 packed with lime-stone to remove sulphur dioxide by water washing.  The hydrogen sulphide remaining is led to an absorber 10 for removal by an organic amine solution and the exit gases pass through an oxide purifier 11 to remove last traces of hydrogen sulphide.  The amine solution is passed to regenerator 13 and the hydrogen sulphide liberated therefrom is recycled to the exit line from scrubber 6 as above referred to.
