Title: Improvements in or relating to processes of purifying crude metal phytates
IPC: C07F9/117
Filed: 1945-09-17
Abstract: Crude metal phytates derived from plant sources such as cereals, soya bean, cotton seed, sugar beet and sugar cane are purified by removal of proteinaceous impurities therefrom by treating the phytates with an aqueous solution of strongly alkaline agents to dissolve or colloidally disperse the impurities.  The metal phytate may be calcium, barium or magnesium phytate and the alkaline agent sodium or potassium hydroxide or carbonate or trimethylbenzyl ammonium hydroxide or mixtures thereof.  After the treatment with alkali, the phytate may be neutralized with an acidic substance such as hydrochloric or acetic acid before being washed with water.  In examples, crude calcium phytate, derived from corn steep water is treated with aqueous sodium hydroxide of various concentrations at elevated temperatures.  The purified phytate, after washing, in some cases with dilute hydrochloric acid is separated by filtration.

Title: Improved process of and apparatus for refrigeration
IPC: F25D3/12
Filed: 1925-09-25
Abstract: 240,485. Slate, T. B. Sept. 27, 1924, [Convention date]. Cold-accumulators; cold-storage chambers. - Blocks of carbon-dioxide ice which volatilize and yield a cold vapour for cooling storage-chambers are carried in good heat-conducting metal containers, which are insulated to prevent too rapid volatilization, the metal containers serving to maintain an approximately uniform temperature in the chamber during the whole period of consumption of the ice blocks. The refrigerator-car or other chamber is fitted with a number of such containers 60 near the ceiling 44, Fig. 1. Open or closed reservoirs 48 of water which becomes frozen may be carried, preferably below a perforated false bottom 47 of the chamber, or a reserve of moisture in the cargo or in the form of water ice packed with the cargo may be employed, to provide latent heat sufficient to prevent undue cooling of the goods. The containers 60 are preferably surrounded by a layer 61 of hair felt insulation, compressed by a winding 62 of adhesive tape, a second layer 63 of hair felt similarly compressed, and an outer covering 65 of canvas or other waterproof material, which is blackened to render it heat-absorbing. The containers are slightly inclined to facilitate drainage when empty, and are supported bv blocks 80 and straps 82. A tray 85 may be provided below each container to direct moisture away from the cargo. The ends of the containers are closed by plugs 66, 67, of balsa wood, having downwardly directed apertures 75, 75<a> for the outflow of the vapour. A tight joint may be effected by a packing-ring 72 compressed between the faces of the plugs and the cylinder by a central bolt 69 having a handled nut 71. This bolt serves as a cold-conducting surface or element. The outflowing vapour has access to the space between the plugs and the entrance of moist air into the vapour passage and container is thus minimized. The chamber is of the usual double-walled construction, with cork, balsa wood or a dead-air space between the walls. The containers are preferably situated at the corners with their outlets directed towards central side doors, where the chamber is warmest.

Title: Anhydrous calcium silicate products
Inventor: SEK GEORGE LAWRENCE KALOU
IPC: C04B28/20
Filed: 1954-08-20
Abstract: A shaped wollastonite (CaO. SiO2) structure is prepared by mixing quick or slaked lime and silica, e.g. quartz, in a molar ratio of about 1 : 1 with about 7.5-.75 times their combined weight of water, shaping the mixture, if necessary after the addition of an agent preventing settling out of the solids, such as spiculated asbestos, highly pulped and beaten paper and starch, indurating at above 173 DEG C. and 125 p.s.i. to form an integrated, porous, crystalline structure of 5CaO. 5SiO2. H2O and subjecting this structure, before or after the removal of uncombined water, to a temperature gradually increasing to 760 DEG C. until wollastonite in a similar form is produced.  One form of wollastonite is formed at 760 DEG C., but if heating is continued up to 1150 DEG C. a second form is produced. Since a contraction is involved in passing from 5CaO. 5SiO2. H2O to CaO. SiO2, it is necessary to allow for this when shaping the initial mixture.  The product is suitable for use e.g. as a refractory, for thermal insulation and for sound deadening, the properties being varied by suitable control of the water content of the initial mixture.  Specification 702,057 is referred to.

IPC: G01R13/22
Filed: 1943-09-21
Abstract: 684,950. Valve switching circuits. SPERRY CORPORATION. Sept. 21, 1943 [June 18, 1942], No. 24438/46. Divided out of 684,948. Class 40 (vi). In a gating valve circuit in which an input signal is passed to a load, an auxiliary circuit is provided so that upon current in the gating valve being suppressed, current flows in the auxiliary circuit, the current in the auxiliary circuit being reduced to a low value when the current in the gating valve is restored, so that the potential change produced at the gate valve load has a predetermined value. The Figure shows a circuit for alternately displaying on a cathode-ray tube, signals applied at terminals 22, 89 feeding the outer control grids of a pair of gating valves 11, 74. A transformer 31, with split secondary, feeds square waves from source 29 to the inner grids of gating valves 11 and control grid of auxiliary valve 94. During a positive half-cycle applied to valve 11, the inner grid passes current, but due to limiting resistance 27 the grid does not rise appreciably above cathode potential, signals applied to the control grid being amplified and fed to the cathode-coupled amplifier pair of valves 43, 63, the negative-going wave from the other half of the transformer secondary cutting off valve 94. During the succeeding half-cycle, gating valve 11 is cut off at the inner grid, the auxiliary valve 94 being driven into grid current to maintain a flow of current through load resistance 41. By suitable adjustment of resistance 97 the current in resistance 41 may be maintained constant or have different values through each half-cycle. In modifications, Figs. 2 and 3 (not shown), the auxiliary valves may be omitted, cross-connections between the screen grid of one gating valve and the anode load of the other providing the auxiliary circuit. Specification 684,948 is referred to.

Title: Reversing gear
IPC: F16H35/00
Filed: 1936-09-09
Abstract: 477,475. Reversing-gearing. SOLTERBECE, O., and KREISINGER, J. Sept. 9, 1936, No. 24580. [Classes 80 (ii) and 80 (iii)] Relates to reversing-gear of the kind in which the reversed drive is effected by applying a brake z, Fig. 2, to a casing a which carries the sliding guided crossheads f of crank linkages connecting cranks d<1>, d<2> on a driving- shaft d to cranks e<1>, e<2> on a driven shaft e. On releasing the brake and engaging a suitable clutch (not shown) to connect the shaft e to a clutch casing b, the linkwork turns solid, yielding a forward drive. The invention comprises means for preventing distortion of through crosshead gudgeon pins i<1>, i<2>, i<3>, i<4>. Thus the pin i<1>, Fig. 1, is pushed radially outwards at one side of the crosshead by a transmission rod 5 from the crank d<1> and is simultaneously pulled radially inwards at the other side of the crosshead by a transmission rod 3 leading to the crank e<2>. There is thus a torque tending to tilt the pin i<1> in a radial plane. To prevent such tilt, the pin i is supported at its two ends in a bracing frame r in turn supported in a second bracing frame p pivoted on a long pin m supported at both its ends by the casing.

Abstract: 950,078. Blasting. BELL INTERCONTINENTAL CORPORATION. July 15, 1960 [July 29, 1959], No. 24695/60. Heading B3D. [Also in Division B5] Moulded parts made of rubber or synthetic material which becomes brittle at low temperatures are deflashed by freezing the flash portions of said parts to a condition of embrittlement and then subjecting said flash portions to abrasive blasting. A batch of moulded articles 10 is supported in an endless conveyer 12 passing round a pair of rotatable heads 18. A loading shoot 22 and an unloading shoot 27 are provided. The conveyer is enclosed within a housing 25 which mounts one or more devices 26 throwing abrasive particles against the workpieces. Spent abrasive particles and the particles of flashings detached from the workpieces pass through the conveyer into a hopper 34 and thence into the boot portion 37 of a bucket elevator 38 delivering into a separator 40 which may include a rotary screen 41 and/or an air separator. Non- re-usable abrasive particles and the particles of flashings are discharged at 42. Re-usable abrasive particles are fed by gravity through a shoot 44 into a storage hopper 32 and thence into a feed spout 70 containing an orifice plate and thence into the throwing device 26. A dust collector 45 has its suction intake duct 46 connected with the interiors of the elevator and separator casings. The workpieces may be frozen prior to being delivered upon the conveyer, as by passing them through a chilled chamber, by spraying them with a cooling fluid, by mixing them with particles of dry ice or by dipping them into a cold liquid bath. The workpieces may be frozen after delivery into the machine, e.g. by mixing dry ice particles into the workpiece load on the conveyer. Preferably, a pipe manifold 50 connected through a control valve to a source of liquid CO 2  has branch pipes 51 carrying spray nozzles 52 projecting into the housing 25. The relatively thin flashings are frozen before the thicker body portions of the workpieces become frozen. The inlet and delivery shoots 22, 27 are provided with controllable closure members to prevent the invasion of a mass of atmospheric air tending substantially to increase the temperature in the housing 25. The apparatus is enclosed within a substantially air-tight thermalinsulated casing 75 having access doors and observation windows. An automatic temperature control system may be provided. The abrasive may be steel shot, aluminium shot or soft grit and may be projected by a sub-ambient temperature gas or air stream.

Patent GB-377830-A (GB)
Title: New or improved plastic product
IPC: C04B28/30
Filed: 1931-09-04
Abstract: A plastic material is prepared by forming in a filling material a hydroxychlorosulphate of zinc and calcium of the formula Ca4O3H2Cl5Zn, 1/2 SO4.  The filler may be inorganic or organic.  In a preferred form the liquid reagents are incorporated with a substance preferably a jellified carbohydrate such as dextrin, starch, &c., which moderates and acts as control on the rate of reaction between the reagents which produce the hydroxychlorosulphate.  The liquid reagents together with the carbohydrate are mixed with the filler, and this mixture is incorporated with a mixture of zinc and calcium oxides and aluminium powder, which latter acts as a catalyst.  Pectin may be added to plasticize the mass.  Examples of organic fillers are dry grass, leaves, straw, old papers, &c. Before incorporation the organic filler may be digested with caustic soda for 6 hours and then submitted to the action of a cutting machine.  It is essential that the reaction should be started under compression which squeezes the liquid re-agents from the colloid and filler and allows them to contact with the zinc and calcium oxides.  The initial pressure should not be lower than 100 kgs. per sq. cm. applied for not more than 3 minutes.
