Patent GB-208842-A (GB)
Abstract: 208,842. Goodliffe, W. E. F. Oct. 14, 1922. Vapour engines.-In vapour apparatus for storing and restoring mechanical energy, lique fled gas stored in a boiler drives an engine and passes to an absorber from which it is drawn off and pumped, preferably through a drier, bacK to the boiler. The engine and pump may be in one. In recharging the boiler, heat may be given to the solution and extracted from the condensing gas. A heat interchanger may be arranged between the boiler and absorber. In charging the boiler B, ammonia is drawn from the absorber A by high and low-pressure corn pressors C<1>, C<2> and passes through an intercnoler F in the absorber and over quicklime in a drier D which is jacketed with the absorber solution. The liquefied ammonia drops to the bottom of D and passes through a non-return valve G and the heat interchanger into the boiler. The interchanger is immersed in a water tank, or the boiler, interchanger and absorber are lagged. The boiler and absorber may work with ammonia solution. The boiler may be separate from the absorber and independently heated, the interchanger being dispensed with. The ammonia may be dissolved in ammonium nitrate or thiocyanate instead of water. Carbon dioxide with a damp carbonate as absorber to form a bicarbonate, may be used instead of ammonia. In this case calcium chloride is used in the drier.

Title: Loading structure for an electric signalling conductor
IPC: H01B11/14
Filed: 1930-07-10
Abstract: 360,933. Wire ; metal tape. STANDARD TELEPHONES & CABLES, Ltd., HUGHES, R. L., and BAGULEY, E., Columbia House, Aldwych, London. July 10, 1930, No. 20886. [Class 83 (ii).] A loading tape or wire for a continuously-loaded cable comprises a core of high-resistivity material and an outer layer or layers of material of lower resistivity and higher permeability than the core. The layers may be insulated from one another. A core comprising a tape of an iron alloy containing 35 percent of nickel and small percentages of silicon or chromium may be sandwiched between two layers of a nickel-iron alloy heat-treated to develop a high permeability, the layers being continuously welded to the core and the composite tape thus formed being rolled down'to the requisite dimensions. In modified constructions, a layer of metal or alloy, which is subsequently heat-treated to develop a high permeability, is deposited on a high-resistance core, or a homogeneous tape may have its outer layer treated to alter its magnetic characteristics, the edges of the tape being trimmed to avoid oontinuity of the outer layer. For example, a nickel core may have iron diffused into its surface by cementation. In a further arrangement, a loading structure is formed as a unit of stranded wires, the innermost wire having higher resistance and lower permeability than the outer wires. The inner and outer wires may be of the same material, some of the strands being treated to change their characteristics, but preferably the wires are of different materials. The wires may be insulated from one another. Specifications 313,584, 329,700, [both in Class 36, Electricity, Conducting &c.], and 343,982 are referred to.

Title: Improvements in or appertaining to terry motions for looms for weaving
IPC: D03D27/08
Filed: 1919-08-29
Abstract: 145,306. Stanworth, J., and Stanworth, W. K. Aug. 29, 1919. Pile-fabric looms. - In a terry motion, a weighted hooked lever h pivoted on a lever g is normally maintained out of the path of a projection n on a swinging lever a by a spring-controlled finger &c. k of a lever connected by a wire &c. m to a treadle or other part of the shedding- mechanism. When terry is to be formed, the finger k is moved away from the lever h, which thereupon moves into the path of the projection n. The lever g is thus oscillated and causes the release of the reed v through intermediate levermechanism. The lever a may be rocked through a connexion d by an eccentric on the crank-shaft. A stop w on the lever a limits the return movement of the lever h under the action of the finger k.

Title: Device for filling containers with liquids
IPC: B67C3/30
Filed: 1955-07-22
Abstract: 845,505. Controlling liquid levels; weighing apparatus. WADDINGTON, R. S., and DUVAL, B. Oct. 22, 1956 [July 22, 1955], No. 21236/55. Classes 123(1) and 143 [Also in Group XVII] An apparatus for filling cans by weight with liquids that have a tendency to froth comprises a rack 32 operable by a hand wheel 33 to lower a feed pipe 5 to the bottom of a can placed on a weighing platform 29. When the pipe 5 is at the correct depth in the can a projection 24b operates a plunger switch 24a to permit a gravitation flow of liquid into the can until the exit aperture of the pipe 5 is covered whereafter a centrifugal pump 13, or other suitable means, is brought into action by a delay switch to speed the filling. When the can is full a mercury switch (not shown), associated with a balance beam 28, stops the pump. The rack 32 is then operated to raise the tube 5 up through a cup 2 until a member suspended from the bottom of the tube 5 engages with and acts as a stopper for the cup 2 (see Group XVII). A slide 281 on the balance beam allows the weight to which the mercury switch reacts to be adjusted. The act of placing a can under the pipe 1 rotates a crank 25 to actuate a safety switch. The crank 25 carries a drip funnel 26 drained by a waste-pipe 27. The delay switch may, instead of actuating the pump 13, bring into action a high pressure liquid supply provided separately from a lower pressure supply used in the first-phase of the filling cycle or to operate a throttle-valve arranged to give two separate rates of delivery from a high pressure supply.

Patent GB-652376-A (GB)
Title: Improvements in or relating to the refining and decolorizing of glyceride oils
IPC: C11B3/00
Filed: 1947-08-06
Abstract: Glyceride oils are refined and decolourized by contacting the oil with a liquefied normally gaseous hydrocarbon in a temperature range near the critical temperature incwhich solubility decreases as temperature increases and at a temperature selected to fractionate the solution of the oil and solvent into an upper phase containing substantially decolourized oil and a lower phase containing substantially all of the colour bodies in the oil. This latter phase is insoluble in the solvent and comprises mucilaginous, colloidally dispersed resinous material together with the colour bodies, which, after standing, may be separated from the upper phase.  If the oil contains phosphatides, as in the case of soyabean oil, these are also separated in the lower phase since they are insoluble in the solvent. Although the mixture of impure oil and solvent may be heated under pressure, heating may be unnecessary if the temperature of the solvent and oil is sufficiently high so that their mixture separates into the upper clear phase and the lower dark coloured phase.  The solvent may comprise ethane or butane, but propane or a mixture of normally gaseous hydrocarbons is preferred.  The solvent is normally used in excess of the oil such as about 8 volumes of the solvent to 1 volume of the oil.  The decolourized, partially purified upper phase may then be fractionated at an increased temperature, such as 65 DEG C. when propane is used, to precipitate a second lower phase containing most of the purified triglycerides and leaving other impurities such as free fatty acids in the upper phase. Specification 469,201 is referred to.

Abstract: 1,261,745. Shaping sliding clasp fasteners. B. POREPP. 28 April, 1969 [27 April, 1968], No. 21638/69. Heading B5A. Two rows of sliding clasp fastener links are produced simultaneously by apparatus comprising a roller 1 with two rows of pins 2, 3 relatively staggered, between adjacent pins of which two filaments 10, 11 are fed by pairs of rollers 4, 5 and 6, 7 respectively. Projections 8, 9 on the rollers 5 and 7 are arranged to flatten the filaments at positions spaced by the length of a link such that when a filament is fed between a pair of pins to meet an abutment pin, the filament will bend at the flattened part. When a link has been formed the roller 1 is moved a distance equal to the pitch of adjacent pins in a row so that each filament is shaped around a pin and is ready to be fed between an adjacent pair of pins. The so formed loops are flattened by a stamper 16 and fed into a heated guide channel for stabilizing the link shape before being removed from the roller. Additional projections 17, 18 are provided on the rollers 5, 7 which engage recesses 17a, 18a in the opposed rollers 4, 6 to form shaped areas in the filaments which, when the loops are flattened create engagement or meshing surfaces for the flattened areas of the other row of links.
