Title: Improvements in dishwashing machines and the like
IPC: A47L15/23
Filed: 1944-02-10
Abstract: 566,690. Dish - washing machines. PIPE, H. L. Feb. 10, 1944, No. 2469. [Class 138 (i)] In a machine for washing and sterilizing dishes &c., the dishes are placed in a basket 25 inserted in a chamber 11 fitted with a sliding door 19 and fitted with upper and lower rotary spray tubes 24, 21, which are mounted on ball bearings and are supplied by pipes 12, 13 with first a mixture of soap and water and then pure water, the supply being cut off automatically at the end of each complete cycle which is initiated automatically by the closing of a switch 68 when the door 19 is closed. The momentary closure of the switch is adapted to energize an electromagnet 76 which closes a switch 70 and causes energization of the motor 45 which operates the control shaft 44. The switch is held closed by a latch 86 which is released by the energization of an electromagnet 90 by closing of a switch 69 by pin 93 on a cam 54. The hot water is supplied from a tank 17 connected to a water main 16 and fitted with an immersion heater 31 controlled by a thermostat 32 set to maintain a temperature such as 180‹ F. The soap is supplied from a tank 36 by a reciprocating pump 34, the piston 40 of which is reciprocated by a crank 41 on a shaft 43 driven by reduction gearing, comprising a pair of worm and wormwheels 49, 48, 47, 46 from the shaft 44. One revolution of the shaft 43 corresponds to a complete cycle of the machine. The shaft 43 is fitted also with a cam 54 which opens a normally spring-closed valve 51 to permit hot water to be pumped by a rotary sliding vane pump 14 to the pipes 12, 13. The areas of the outlets of the pipes 24, 21 are smaller than the cross-sections of the pipes 12, 13, so that the liquid emerges at high velocity to effect efficient cleansing. Check valves 38, 39 permit inflow of soap during the suction stroke of the pump and outflow during the compression stroke, and during the suction stroke water alone is supplied to the sprayers, and during this stage rinsing and sterilizing takes place. The drain outlet is fitted with a strainer to stop solid food particles from choking the drain.

Patent GB-566167-A (GB)
Title: Improvements in and relating to the preparation of cooked starchy vegetables in powder form
IPC: A23L19/15
Filed: 1942-03-02
Abstract: Cooked starchy vegetables, such as mashed potatoes, are prepared in powdered and readily reconstitutable form by mixing the cooked and mashed vegetable with such a quantity of "seed" powder, preferably an approximately equal weight, as to yield a moderately dry friable powder, which is reduced, as by sieving, to the desired state of fineness and dried, the reducing and drying operations being so carried out as to avoid breaking or bursting the vegetable starch granule - containing cells.  Initially, the "seed" powder is prepared by mixing some of the cooked and mashed vegetable, which has been dried and ground, with, preferably an equal weight of, the wet mashed vegetable, sieving and drying and repeating the operations, except for grinding, with further batches of wet material until the product is substantially free from hard or horny material; thereafter the "seed" powder for any particular batch is retained from a previously treated batch.  The mashed vegetable may be frozen and allowed to thaw before treatment and the initial "seed" powder may also be made from previously frozen mashed vegetable.  The water content of the mixture before sieving is preferably between 40 and 50 per cent, and of the final powder 6 to 8 per cent by weight.  The mixture may be sieved through a 12 to 18 mesh screen by shaking or gentle rubbing. The dried powder may be finally sieved through a 25 to 60 mesh screen and the grains retained by the screen used as seeding material. Drying may be effected in a vacuum drier at a relatively low temperature or by a current of warm or hot air, preferably at a temperature not exceeding 250 DEG  F.

Abstract: 493,254. Wire fabrics. STEVENS, A. H. (Appleton Wire Works, Inc.) Jan. 28, 1938, No. 2766. [Class 142 (iv)] . Flat ribbon-like warp wires 10 are interwoven with tubular weft wires, which become deformed and produce flat knuckle surfaces 11a, 11b those 11a on the paper side being in the plane of the warp knuckles, whilst those in the opposite and wear side are offset upwardly, so that the wear is taken on this side by the warp wire knuckles. The tension of the top shed is arranged to be less than that of the bottom shed. Uniformly spaced flat warp and weft knuckle surfaces result on the paper side. The tubular weft wires may be formed by extrusion or drawing. In the latter case, the weft wires are preferably woven with the seam on the under side. Specification 482,273 is referred to.
Patent GB-920155-A (GB)
Title: Remotely operated gripping tool
IPC: G21C19/105
Filed: 1961-01-24
Abstract: 920,155. Servicing reactors. UNITED STATES ATOMIC ENERGY COMMISSION. Jan. 24, 1961 [March 21, 1960], No. 2768/61. Class 39 (4). [Also in Group XXX] A grab for handling a fuel element in a reactor comprises a pair of jaws 18A, 18B pivoted at 32, 34 to a block 22 integral with a tubular neck 26 and a housing 24. A plunger 16 having cam surfaces A, B at its lower end is slidable within the neck 26 and block 22 and is biased to its lowermost position, shown, by a spring 88. The cam surfaces co-operate with rollers 36, 38, 42 and 44 on the jaws 18A, 18B so that when the plunger is in the position shown the jaws grasp a knob 11 on the fuel element. Energization of a solenoid 92 causes the plunger 16 to move upwards and open jaws. Balls 62 are received in openings 56 in the neck 26 and these balls also engage a groove 76 or 78 in the plunger to lock the plunger in the jaw closed or jaw open position, respectively, the balls being held in the locking position by a flange at the lower end of an extension 54 of a sleeve 14. The sleeve 14 is slidable on the neck 26 and when it is moved down from the locking position shown, so that the extension 54 rests on the block 22 the balls 62 may move out of the groove 76 or 78 and permit the solenoid 92 or the spring 88 to move the plunger to its other position. The grab is lifted by a cable 13 attached to the sleeve 14, the load being transmitted through the engagement of a shoulder 72 on the extension 54 with a shoulder 66 on the neck 26 whereby the jaws are locked in the open or closed position whenever the weight of the grab is taken by the cable 13. This weight may be removed from the cable by lowering the grab so that a member 46 rigid with the block 22 engages the knob 11, continued lowering of the cable causing the sleeve 14 to unlock the balls. Thus when the grab is lowered on to a fuel element with the jaws open, the spring 88 will automatically cause the jaws to close on the knob 11. The member 46 also serves to guide the lower end of the plunger. Micro-switches 94, 96 are actuated in the two extreme positions of the plunger and may be connected to safety devices.

Patent GB-760572-A (GB)
Title: Treatment of acid mixtures containing formic acid
IPC: C07C51/48
Filed: 1953-02-04
Abstract: A fatty acid mixture containing formic acid in minor proportion, together with or in the absence of a minor proportion of water, is freed of said formic acid by treating said mixture with more acetic anhydride than the total amount required to react with any water originally present and with water produced by decomposition of formic acid, thereafter heating the mixture, preferably at a temperature in the range 100 DEG  to 120 DEG  C., for sufficient time to decompose the formic acid, adding to the product at least sufficient water to convert the remaining acetic anhydride to acetic acid and, if necessary, further heating to convert said acetic anhydride to acetic acid.  The process may be applied to an acid mixture comprising a major proportion of acetic acid and a minor proportion of formic acid.  In order to produce anhydrous acetic acid, the amount of water added to the product is just the amount needed to convert the remaining acetic anhydride to acetic acid.  The process is particularly suitable for treatment of fatty acid mixtures comprising acids having up to 4 carbon atoms per molecule and up to 15 per cent by weight of formic acid.  Such mixtures may be produced by partial aerial oxidation of hydrocarbons, such as paraffins or cycloparaffins with subsequent treatment of the product by azeotropic distillation, using for example hexane or toluene as an entrainer, to remove most of the formic acid, ketones, esters and water as an overhead product. The bottoms product so obtained contains acetic and propionic acids, together with formic acid and water.  In an example, a mixture of acetic acid, formic acid and water is distilled in the presence of 45 per cent by weight of acetic anhydride using a reflux ratio in excess of 40:1, and the amount of water necessary to convert the acetic anhydride to acetic acid is added to the bottoms product.  The Provisional Specification describes a broad process wherein formic acid is removed from acid mixtures by heating with acetic anhydride to decompose at least part of the formic acid.  Said heating may be effected in a fractional distillation, acetic acid and excess acetic anhydride being recovered as separate fractions if required. Specifications 721,301 and 744,087 are referred to.
