Patent GB-241149-A (GB)
Title: Manufacture of cellulose compounds
IPC: C08B15/06
Filed: 1924-11-20
Abstract: Cellulose derivatives are prepared by reacting with an ester of an inorganic acid on a salt of a N-substituted or an unsubstituted cellulose thiourethane, or alternatively on a N-substituted or an unsubstituted cellulose thiourethane in the presence of a basic substance, particularly an alkali.  The products are insoluble in water; some are soluble in basic solvents such as aqueous alkalies, and aqueous solutions of organic bases, and also in organic solvents such as strong acetic acid and aqueous alcohol, while others are insoluble in aqueous alkalies but dissolve in a wide range of organic solvents; the solubility of the product depends on the nature and proportion of the inorganic acid ester employed.  Suitable inorganic acid esters are the alkyl, aryl and aralkyl halides, sulphuric acid esters or phosphoric acid esters, and the esters may be diluted with a solvent such as benzole or benzine.  According to one method, the cellulose urethane &c. prepared as described in Specifications 231,801 and 231,802, either in the crude condition or after purification, is converted into a salt, for example, a silver salt or an alkali salt as prepared by dissolving the thiourethane in alkali solution, and then treated with the ester of the inorganic acid either in the cold or with the aid of heat and in the presence or absence of free alkali; alternatively, the thiourethane may be rubbed up or kneaded with powdered alkali or with strong alkali solution, or with a mixture of these.  The alkali may be used in the calculated quantity or in excess and under such conditions that at least a part of the alkali remains undissolved.  When the process is carried out in solution, the product is isolated by filtration, straining, centrifuging, &c., followed by washing or drying; or it may be dissolved and then applied to technical purposes either after previous separation of the bulk of the washing-water or after previous drying; or the precipitate may be treated with a dilute acid before or after washing.  If the operation is not conducted in solution, the final products may be worked up by mixing the reaction mass with hot or cold water, separation of the undissolved portion, and then washing &c. as above.  Examples are given using as the starting materials phenyl- or tolylcellulose-thiourethanes and employing different proportions of di-ethyl sulphate, ethyl chloride and other inorganic acid esters, and different concentrations of caustic alkali solution or even solid caustic alkali.  The products can be used in the manufacture of plastic masses, substitutes for celluloid, horn, ebonite, ivory, glass, tortoiseshell, wood &c., varnishes, lacquers, films, artificial fibres, adhesives, cements, finishes and coatings, waterproof materials, artificial leather, bed sheets, bookbinders and tracing cloth, electrical insulating-compositions.

Title: Method of making push rods

Abstract: 1,038,477. Making push rods; extruding; forging. G.K.N. SCREWS & FASTENERS Ltd. June 23, 1965 [July 7, 1964], No. 27859/64. Heading B3A, B3H and B3P. A method of making a hollow metal push rod comprises the steps of forming a solid slug from stock, forming an axial hole through the slug, extruding the slug to form a tube, and forming each end into a port hemispherical shape. As described, the slug is cut from wire, Fig. 1 (not shown), and put in a die in which both ends are planished flat and central conical depressions are formed by a punch, Fig. 2 (not shown). The slug is then placed in a further die, Fig. 3 (not shown), where the conical depressions are enlarged by a punch into holes passing from both ends substantially through the slug leaving a thin wall of metal which is then removed by punching, Fig. 4 (not shown). The slug is next placed in a die 50, Fig. 5, having a restricted opening 56 through which the slug 5 is extruded by a ram 54 having a projecting mandrel 53 which passes through the slug. When the slug is extruded to the extent of the slug 5 as shown in the Figure, the ram is withdrawn and another slug placed on top of the one already in the die which can then be completely extruded as a tube 5a. After a further similar tube forming extrusion operation the tube is gripped in clamps whilst the ends are countersunk, Figs. 7 and 7A (not shown), and finally gripped in clamps whilst the ends are forged into a hemispherical shape, Figs. 8 and 9 (not shown). Dependant upon the angle of the countersink, the ends may have central holes 88, Fig. 9 (not shown), communicating from the exterior to the interior.

[Classes 83 (ii) and 83 (iv)] [See also Group XL] Cores, coiling; welding.-Helically wound grids for radio valves are made by placing nickel &c. side wires 3 lengthwise along an alundum &c. coated iron mandrel 1, winding a molybdenum &c. wire 4 having a less coefficient of expansion than the core wire 1 helically around, then heating the assembly in a furnace with hydrogen atmosphere to weld the helical wire to the side wires, then dissolving the alundum from the mandrel in a hydrochloric acid bath, so that the mandrel can be withdrawn from the grid. The iron mandrel expands more than the grid and so exerts a welding pressure thereon. Fig. 5 shows apparatus for continuous production in which a coated mandrel wire 1 and side wires 3 are pulled out by a screw-fed clamp 17 while a spool 23 wraps another wire helically around the assembly and the whole then passes on to a furnace 27 at 1350‹ C. which welds the helical to the side wires. The grid so formed is then cut into lengths and immersed in acid to loosen the mandrel wire and allow its removal. The core wire may be 100 mils. diameter, the side wires and the winding wire 1 mil. diameter. This grid is said to reduce shadow effect.

Abstract: 719,606. Bottle washing machines. SEITZWERKE GES. Nov. 14, 1952, [Nov. 15, 1951.] No. 28705/52. Class 138 (1). A bottle washing machine fitted with a device for rinsing the bottles with jets of liquid and provided with baskets for accommodating a plurality of bottles whereby each bottle is disposed in an individual compartment, wherein two nozzles adjoin each compartment and are so arranged above the compartment that their jets are directed towards diagonally opposite corners thereof. Nozzle pairs 12, Figs. 1 and 3 are disposed on the underside of a jet pipe 11, rotatably mounted in the machine as by a flange 13 engaging in a flange 14 of a fixed liquid supply pipe and a pin 15 engaging in a bearing support 16 of the machine. The jet pipe is fixed in operative position by means of screws 2, Fig. 2, carried by angles 20 on the flange 14, clamping against the flange 13. A partition 17, or partitions, is or are provided within the pipe 11 to more uniformally distribute the liquid to the nozzles. Instead of a partition 17 a pipe may be inserted within the pipe 11 so that the annular passage between the two pipes serves to feed half of the nozzles, whilst the inner pipe is then arranged to feed the other half of the nozzles. A side pipe 23, closable by a cap 23, is provided on the upper side of the pipe I adjacent the pin 15. Although a bottle 19 may rest against a side or corner of a compartment of a bottle basket 18 the corners of the compartment are always clear enough to allow passage of the jets which are arranged to deliver liquid obliquely on to the wall and neck of the bottle and thus remove labels therearound. These jets also remove the label straps adhering to the stirrup for the bottle stopper. If owing to a failure of the machine filter, scraps of paper are recirculated to the jet pipe 11 and clog the nozzles 12, the nozzles may be readily cleared. The cap 22 is removed and the flange 13 unclamped and the jet pipe turned through 180 degrees. The nozzles 12 are then cleared by pushing a rod therethrough and liquid is circulated for a period so as to carry the label scraps out through the pipe 23, after which the cap 22 is replaced and pipe 11 reclamped in its operative position.

The connection 10 allows fan 4 to connect with the channel 12 or 13 which is not coupled with the fan 6. The channels 12, 13 each contain a removable pervious heat-absorbing and moisture-retaining mass 15, 16, e.g. of silica gel or brick chips, having an embedded heater coil energized by contacts 14b on the walls of the channels. The connection 10 is swung, by known relay means, to connect the channels in alternation with the fan 6, so that the heat and moisture of the foul air is absorbed in one mass 15 or 16 and is recovered by the fresh air flowing through the other mass. The periodicity of reversal of the connection is variable, and becomes less frequent as the working of the plant proceeds. The heaters are in operation only when fresh air is being drawn through the mass. The flaps 18, 21 are pivotal at 20 to permit the removal of the mass 15, 16.
