Title: Improvements in or relating to the production of organic sulphur-containing compounds
IPC: C07C329/00
Filed: 1964-05-14
Abstract: Organic sulphur-containing compounds are prepared by reacting organic halogen-containing compounds with a salt of trithiocarbonic acid in an amount sufficient to form a trithiocarbonic acid monoester salt and decomposing the latter e.g. with a non-oxidizing acid, or permitting it to decompose to form the required organic sulphur-containing compound and CS2, the reactions being performed in an inert solvent.  The CS2 is preferably distilled off during the decomposition step.  The free monoester may be isolated as an intermediate in certain cases.  Starting materials with one halogen on a given carbon atom give -SH compounds, with 2 halogens on one carbon -->C = S compounds and with 3 halogen atoms on one carbon, -CSSH compounds or their derivatives.  Examples describe the preparation of: EtSH; n-BuSH; n-C6H11SH; C6H5CH2SH; HOCH2CH2SH; HOCH2CHOHCH2SH; HSCH2 COOH; HSCH2COOC8H17-i; CH3CHSHCOOH; C6H5COSH; HSCH2CH2SH; polythioformaldehyde; HSCH2SH; polythiobenzaldehyde; and C6H5CSSH.  HSC(S)SCH2COOH is isolated as an intermediate in Example 8.  Ethylene trithiocarbonate is obtained as a by-product in the preparation of HSCH2CH2SH from sodium trithiocarbonate and ethylene chloride in Example 13.  Examples 8 and 12 refer to the reaction of sodium trithiocarbonate with more than one molecular proportion of sodium monochloroacetate or benzoyl chloride giving HOOCCH2 SC(S)SCH2COOH and C6H5CO-S-COC6H5 respectively.ALSO:Polythioformaldehydes (Examples 14 and 15) and polythiobenzaldehyde (Example 16) are prepared by reacting sodium trithiocarbonate with methylene chloride and benzal chloride respectively in an aqueous medium.

Title: Improvements in or relating to the production of hydrogen peroxide
Inventor: HOWE BRIAN KEITH
IPC: C01B15/023
Filed: 1958-06-24
Abstract: In a cyclic process for the production of hydrogen peroxide involving successive reduction and oxidation of an anthraquinone solution and aqueous extraction of hydrogen peroxide, the solution, or degraded solids separated from the solution, have their peroxide-producing capacity regenerated by treating with O2, an O2-containing gas, H2O2, or other oxidizing agent in the presence of a water-soluble base. The treatment is carried out after extraction, but before reduction, and the bases may be used in alcoholic solution.  A portion of the solution may be withdrawn from the cycle for treatment and returned after water washing.  Exemplified bases are aqueous NaOH and KOH, alcoholic KOH, sodium ethoxide, ammonia, Ca(OH)2, pyridine, and trieththylamine.  This oxidation treatment may be combined with the known regeneration treatment of contacting with porous artificial alumino silicates, e.g. sodium aluminium silicate at 90 DEG C.  This contact may be before the oxidation treatment, or on a separate portion of solution simultaneously. Specifications 465,070 and 838,939 are referred to.

Patent GB-871791-A (GB)
Title: Improvements in or relating to character recording apparatus
Inventor: DAVIS ROGER ARTHUR
Filed: 1958-06-25
Abstract: 871,791. Selective printing. INTERNATIONAL COMPUTERS & TABULATORS Ltd. .June 9, 1959 [June 25, 1958], No. 20365/58. Class 100(4). A cyclically pulse operated recording apparatus for printing ordinary and braille characters, or punching, is operated by a signal source represented by two pulses, spaced in two time periods which set, first and second storage devices e.g. magnetic cores 12-1 to 12-N, and magnetic core 19, which together with a rigidly synchronised pulse generator, control the operation of the means to record the signal in a paper web 40. As described the apparatus comprises columns of continuously rotating type-wheels 2 all fixed to a shaft 1 to which is also coupled a photo-electric pulse generator 3 and a distributer 5, the signal pulses being derived from punched cards sensed at first and second sensing stations 6, 15. The record cards have numeral positions 9-0 and zone positions 1, O, X, Y which constitute the two time pulse positions and the cards are-synchronised with the pulses generated by photo electric cells, 22 23 by the rotation of the slotted disc of the generator 3. Lamp 20 shines through the shallow slots for each wheel character position or corresponding to a zone position perforation, while lamp 21 only shines through the deep slots at the group positions or corresponding to numeral characters. The pulses from the cell 22 are connected by the distributer 5 and leads 31 to switch windings 11-1 to 11-Y of four group magnetic stores 12 and to winding 1 1-N of a further store 12N. These five cores comprise the first magnetic store and perforations sensed by the first sensing station cause setting of the cores. The card is then sensed by the second sensing station 15 and sets the second store 19. The cards are fed in the order 9-1, O, X, Y so that in the case of a character code requiring a zone pulse and a numeral pulse the store 19 is operated when the numeral perforation arrives at the second station. A pulse from photo-electric cell resets the store 19 so that the read-out winding 26 fires a valve 27 whose anode is connected by cam contacts to a resetting winding of the first store. The valve remains fired until the cam contacts 28 open which occurs after the last numeral position has passed the second sensing station. As a result, resetting of the cores 12-1 to 12-N will occur during the first cycle of pulses from the photo-electric cell 22 following the resetting of the second store 19. A common read-out winding 33 passes pulses to a valve 34 and the timing of the pulse according to which core was set causes actuation of the printing magnet 35, connected in series with a capacitive quenching circuit.41-44 so that there is a rapid blow by the hammer 38. The first storage device is duplicated by an identical device 49 to enable a following card to be handled in the first sensing station while the first card is still in the second station.

Title: Pure fluid sensing apparatus
Inventor: EASTMAN JAMES M
IPC: G01K11/24
Filed: 1968-04-30
Abstract: 1,216,913. Fluid-pressure servomotor systems. BENDIX CORP. April 30, 1968, No. 20381/68. Heading G3P. [Also in Divisions F1 and H4] An apparatus for sensing a variable condition of a relatively high-pressure fluid in a chamber 38 comprises pure fluid means T generating pressure oscillations of predetermined frequency which propagate through the high-pressure fluid, pure fluid sound receiving means R located in the chamber in spaced relationship with the means T and adapted to resonate at the predetermined frequency to produce corresponding output signals and pure fluid valve means A responsive to the output signals for generating an output pressure representative of the condition to be sensed, fluid control means O controlling the operation of the means T and valve A in timed relationship. The chamber 38 may be the discharge section of a combustion chamber 36 in a gas turbine and the  variable condition may be temperature. The means O consists of a flip-flop oscillator having its output passages 49 and 51 connected to a vortex amplifier 80 controlling the outlet 70 from a Hartmann oscillator 64 and to a control port 138 of the valve A. A second control port 120 is connected through a duct 116 having a series of resonant chambers 122, 124, 126 with a tube 118 situated at the focal point of a reflector 112 and adapted to resonate at the frequency of the oscillator 64. Whenever a pulse is applied by the flip-flop oscillator to the port 138, a lack of pressurized fluid occurs at a control port 90 of the vortex amplifier permitting hot combustion gas to flow through the oscillator 64 and excite the gas 74 in a plug 72 into a selfoscillation to produce a series of gas pressure waves at the tube 118 to produce a pulse in the port 120 opposing that from the port 138 and causing a control jet 134 to be deflected from a passage 140 to a passage 136. The time during which the power jet is biased to passage 140 is proportional to the time taken by the pulse to travel from the generator to the receiver and to the square root of the temperature of the gas in the chamber 38. The flow through the passages 136 and 140 may be time integrated by restrictors 144, 146, 150 and 152 and by chambers 142 and 148 to provide a pressure differential P 1 -P 2  which is a function of temperature. A diaphragm 60 connected to a fuel control for the turbine is actuated by this differential to maintain the gas temperature at the required value.

Filed: 1956-07-23
Abstract: 843,138. Applying adhesive tape to containers. COW & GATE Ltd., and CHARLES, G. K. June 27, 1957 [July 23, 1956], No. 20408/57. Divided out of 842,350. Class 73. Relates to a machine for taping containers 7 which are conveyed along a track so that each engages for initial adherence with adhesive tape 21 led from a spool 22 to a pivoted spring- urged tape guide arm 1 extending across the track, the tape being then cut off as the arm 1 is swung back by the advancing container to carry the tape against a fixed cutter 26. According to the invention, there is slidably mounted on one side of the track an anvil or abutment 10 against which the end of the tape is pressed by the end 8 of the guide arm 1. The arrangement is such that the anvil 10 means in a straight path for a limited distance while the end 8 of the guide arm moves in an arcuate path as the arm is swung back by an advancing container, so that the tape 21 is held under tension while the container engages in the bight or loop of the tape before the tape reaches and is cut by the cutter 26, by which time the anvil is arrested, the end 8 of the arm 1 has moved away from it and the portion of the tape adhering to the container can peel off its end from the anvil 10. The anvil 10 projects upwardly from a plate 11 having pins 12, 13 sliding in a slot 14 in the frame bar 6. A lever 15 pivoted at 16 is normally held by a spring 18 in contact with the guide arm 1 and has a slot 19 for the reception of a pin 20 on the plate 11. Thus the arm, 1 lever 15 and anvil 10 are moved simultaneously by the advancing container. The container 7 with the portion of tape adhering to it, is conveyed without rotating past rollers or other known means (not shown) by which the wrapping of the tape around the container is completed. Specifications 574,156 and 592,34] also are referred to.
