Patent GB-642318-A (GB)
Title: Improvements relating to absorption media for carbon monoxide and to the treatment of gases containing carbon monoxide
IPC: B01D53/62
Filed: 1947-06-10
Abstract: Carbon monoxide is separated and recovered from a gas mixture such as illuminating gas, coke-oven gas or water-gas, by absorption in and desorption from a medium comprising compounds of monovalent copper dissolved or suspended in aqueous solution together with at least one magnesium compound containing a chloride ion, which is present in such a quantity that there is an undissolved deposit in the medium and which depresses considerably the decomposition pressure of the complex cuprous carbon monoxide compounds formed when carbon monoxide is absorbed by the absorption medium.  Magnesium compounds specified are magnesium chloride, carnallite and kainite.  In one embodiment the gas mixture is passed countercurrently to the absorption medium trickling down an absorption tower, and carbon monoxide enriched absorbent drawn from the bottom is desorbed in another tower at a pressure lower than that of the absorption, carbon monoxide thus released being withdrawn.  To prevent foaming during desorption, the absorbent and carbon monoxide liberated may be passed in the same direction through the tower or phenol or a higher alcohol may be added to the absorbent, the absorbent being cleaned and cooled, if necessary, before being returned to the absorption tower.  The gas mixture may be heated before or upon entering the absorption tower. The desorption may be effected in stages, most of the carbon monoxide being drawn off under medium vacuum and the remainder under higher vacuum.  Absorption media forming carbon monoxide complexes having different decomposition pressures may be used, the medium forming a complex with the highest decomposition pressure, such as a cuprous chloride solution without a deposit, being used first, followed by media according to the invention. The gas mixture may be subjected to two or more treatments so that in each successive treatment a quantity of absorption medium is circulated in a separate cycle, each cycle including separate absorption and desorption apparatus; the composition of the absorption media in the various cycles may be different or the same, the degree of vacuum being greatest in the first cycle and correspondingly smaller in the subsequent cycles.

Patent GB-277590-A (GB)
Title: Improvements in or relating to electric remote control systems
IPC: H02J13/00
Filed: 1926-07-16
Abstract: 277,590. Automatic Telephone Manufacturing Co., Ltd., and Remington, C. July 16, 1926. Drawings to Specification. Distant control systems; tell-tale apparatus.- Relates to a system for electrically controlling and supervising apparatus units, such as circuit breakers, located at a remote station. Each circuit breaker has at the control station a corresponding selecting key, which when operated causes the transmission, over two line wires, of a train of impulses under the control of a step-by-step switch. The impulses operate synchronously moving switches associated with the circuit breakers, selection of any one of which is determined by the transmission, at a point in the cycle characteristic of the operated key, of a special impulse over a third line wire. When a circuit breaker changes its position the operation of a switch associated with the circuit breakers is initiated to control the transmission of a code of impulses which is characteristic of the positions of all the circuit breakers and operates synchronously a switch at the control station associated with supervisory lamps. The control and supervisory system is identical with that described in Specification 277,460. The invention resides in the provision of arrangements whereby in the event of the switches at each station becoming out of step, the transmission of impulses is repeated. This repetition is continued until synchronism is again established. Specification 277,460 describes the arrangements for causing the retransmission of signals in the event of the supervisory switches becoming out of step, but the present. Specification states that the arrangements may also be used in conjunction with the circuit breaker selecting equipment. If the receiving switch is not in its normal position at the end of a selecting signal, a relay at the substation causes the operation of the supervisory equipment to control a relay at the control stations and thereby permit the operated selecting key to again become effective. Specifications 252,231, 258,012, 258,178 and 258,179 also are referred to.

Title: Coin tester
Filed: 1961-04-28
Abstract: 914,007. Coin-testing. CARI G.m.b.H. & CO. April 28, 1961 [May 12, 1960], No. 15504/61. Class 27. A coin-tester, particularly for vending machines, comprises two or more inclined tracks m, m<SP>1</SP>, a weight-testing balance k, k<SP>1</SP> at the beginning of each track and thickness-testing projections z and a hole-detecting feeler fe which co-operate to test the contour of the coins. Inserted coins pass down a funnel c, the larger coins being tested for diameter between elements g, f, and fall to the balances k, k<SP>1</SP>. Sufficiently small coins pass between the bentover ends of the balance k to the lower balance k<SP>1</SP> but coins of roughly correct larger diameter are retained on the upper balance and, if of correct weight, they tilt through the required angle to deliver the coin to the track m. The counterweight for the balance may be an adjustable nut l or may be a weight carried by a hairpin clip displaceable in two bores in the balance. The tracks m, m<SP>1</SP> are adjustable vertically in slots m<SP>11</SP> and have a slot n, n<SP>1</SP> for rejecting toothin coins to a reject channel k 3 . The thicknesstesting projections are sip screws z projecting into the appropriate track and a pin fe<SP>1</SP> on each feeler fe projects between the first four of each set of screws. A coin which is inadequately embossed and is in consequence excessively thin is first tilted clockwise by the pin fe<SP>1</SP> and then counterclockwise into engagement with the last pair of screws z and is retained by them. A coin of too-small diameter falls through an aperture i or i<SP>1</SP>, assisted by the feeler. Accepted coins pass over webs o, o<SP>1</SP> to their appropriate delivery channels. Most of the parts of the tester are made of plastic. Coin-clearing.-A plate b forming one side of the coin tracks and carrying the balances k, k<SP>1</SP> is provided with a spring-loaded hinge r so that it can be pivoted by an operating member b 1  to release trapped coins.

Title: Improvements relating to oil filters
IPC: B01D27/02
Filed: 1949-06-13
Abstract: 662,282. Filters. BICKIE, H. M. June 13, 1949. [July 23, 1948] No. 15659/49. Class 46. [Also in Group XXXIV] An oil filter assembly comprises a casing 15, Fig. 1, having top and bottom openings and a filter cartridge 11 having along its axis a tube 14 perforated only within the cartridge and secured to the casing 15 around the openings, the whole being held down on a base 40 by a bolt 60, which serves also as outlet tube. Oil to be filtered passes through a pipe 47, passageway 44 and a groove 45 registering with an opening 21 into the space between the casing 15 and the cartridge 11. A slightly modified mounting base is described (Fig. 2, not shown). The casing with its cartridge is replaceable as a unit when clogged. A base having passages for permitting either fullflow or byepass filtration may be used: two types of filter are then used. For full-flow filtration the cartridge 11 has a low-resistance impregnated cotton waste filling, and the casing 10<SP>1</SP>, Fig. 3, has a length such that the bolt 60 when screwed home does not reach down to a spring-pressed ball 88, Fig. 4, protruding into a recess 83. Oil from the-pump then passes along a passage 103 in a block 100, up a passageway 82. into a groove 85 and around the filter element, then through the element and a hole (not shown) into the interior of the bolt 60. The filtrate then passes into the recess 83, and along passages 89, 90, forces open ball valve 96, and reaches the bearings via passages 95 and 105. For byepass filtration a casing 10<SP>1</SP> is used having a high-resistance element, and a shorter length such that the bolt 60 when screwed home forces the ball 88 off its seating but does not obturate a passage 84. Some of the oil thus passes up the passage 82 as before, Fig. 7 (diagrammatic) and into the casing, the filtrate passing from the recess 83 through passages 84 and 104, Fig. 3, to the engine sump. The remainder of the oil, under the back pressure set up by the element, forces open the ball valve 98 and passes to the bearings along passages 92, 95 and 105. This oil also acts on ball valve 96, (which is open during full-flow filtration), in a direction causing it to close. Specification 662,330 is referred to.

Title: Improvements in cellulose derivative compositions
IPC: C08L1/08
Filed: 1942-11-06
Abstract: To reduce the destructive action of ultra-violet light on a cellulose ester or ether, e.g. in the form of a fibre, foil, or film, a small proportion of an ester of low volatility of an aromatic hydroxy carboxylic acid with a phenol, an alcohol containing an aromatic nucleus, or a cycloaliphatic alcohol, is incorporated with the cellulose derivative before or after shaping it into the desired form.  The amount of ester incorporated does not exceed 15 per cent based on the weight of the cellulose derivative.  The ester used is such that it does not lose more than 5 per cent by weight when one gram of it is heated in a dish in air at 60-70 DEG  C. for 20 hours. The ester may be menthyl, or b -naphthyl salicylate.  It may be an ester of a hydroxy benzene or hydroxy naphthalene monocarboxylic acid, e.g. of salicylic, p-hydroxybenzoic, 2-hydroxy-naphthalene-3-carboxylic, and 1-hydroxy-naphthalene-2-carboxylic acid.  The hydroxyl group of the acid may be esterified with a carboxylic acid, e.g. with acetic or benzoic acid.  The ester of the hydroxy carboxylic acid may be obtained with cyclohexanol, menthol, benzyl alcohol, b -phenyl-ethyl alcohol, phenol, a mono-ether of a dihydroxybenzene, p - hydroxy - diphenyl, a hydroxy - diphenyl - methane, a - or b -naphthol, or 4-methoxy-1-hydroxy-naphthalene. The ester of an aromatic hydroxycarboxylic acid and the cellulose derivative may be dissolved in a common volatile solvent and the solution may be extruded or cast to form filaments or films, or it may be used as a lacquer for coating textiles, wood, metal or other articles.  Alternatively, cellulose ester or ether fibres, fabrics or other articles may be allowed to absorb the aromatic acid ester from a solution or aqueous dispersion, e.g. a solution in ethyl alcohol.  The Provisional Specification describes also the use of esters of other aromatic carboxylic acids, including benzoates, aminobenzoates, naphthoates, phenyl-acetates, and cinnamates, and ethyl, butyl, octyl and other alkyl esters of aromatic hydroxy carboxylic acids, and phenyl salicylate.
