Patent GB-141311-A (GB)
Abstract: 141,311. Sterling Telephone & Electric Co., and Davey, W. C. Dec. 31, 1918. Drawings to Specification. Automatic exchange systems.-Relates to relay switching-arrangements for connecting a calling line to an idle selector trunk. In one arrangement, in which the subscriber's line has a connecting-relay for each selector trunk except the last, these relays are energized if the associated trunk is busy and extend to the test lead of the next selector the circuit of a relay, individual to the calling line, which on excitation connects the calling line to the selector trunk and marks this busy by connecting its own low-resistance winding to the selector test lead. In a modified arrangement, each of the connecting-relays has high and low resistance windings, and if all the selector trunks are free when a subscriber calls. all the connecting-relays are energized, each relay (1) breaking the exciting circuits of all subsequent relays., (2) connecting the calling line to the selector trunk, and (3) marking the selector busy by connecting its low-resistance holding-winding to the selector test lead. The arrangements described are identical with those described in Specification 141,106.

Class 34 (ii) [Also in Group I] A conditioning, drying and sterilizing process for cereals consists first in admixing the cereals to be treated with a pulverulent substance, e.g., sand, granular metal, glass powder which is inert to. wards the cereals and having a lower specific heat than the cereals, in a quantity sufficient for filling up all interstices between the cereal grains, this substance being previously raised to a suitable temperature, e.g., 75-120‹C. so as to serve as a heat vehicle by abandoning its heat to the said cereals while sterilizing the cereal surface layer and partially vaporizing the water contained in the cereal grains, then in causing a stream of cold air preferably under depression and in counter-current to flow through the mass of the mixture thus obtained so as to cool the pulverulent substance faster than the cereals and to condense the vapour upon the substance and so to drive away the water, and in mechanically separating the substance and the treated cereals. As shown the cereal to be treated and the pulverulent substance from hoppers 2, 3 respectively, after being mixed in the required proportions by means not shown are fed to an airtight and lagged column 1 down which the mixture falls on to a sieve 9 which separates the grain which is removed at 10 the pulverulent substance being removed at 11 and passed through an oven 12 to heat it before returning to the hopper 3. Air is drawn counter-currently through the column by means not shown, e.g., a fan. Adjusting means are provided at the lower end of the column for regulating the speed of fall of the mixture and consequently the duration of the desiccation.

A second cylindrical overwrap 28 which terminates short of the junctions between parts 12, 14 is then formed. The liner is an integral aluminium body and the filament material is preferably fibreglass coated with an epoxy resin, the vessel being heat-cured when overwrapping has finished and then pressurised so that the liner exceeds the elastic limit and is thus deformed, this being followed by depressurisation whereby the filaments remain in tension to apply an inwards compressive force on the liner.

Abstract: 661,617. Coring apples &c. SMALL, H. J. June 5, 1950 [June 3, 1949]; No. 14989/49. Class 28 (ii). In an apple &c. corer the apple is pressed by hand over a hand rotated tube 1 with end cutting teeth 2, whereby a sliding ejector ring 14 and a core ejecting plunger 13 is pressed back to compress a spring 16 until a pin 15 coupling 14 to 13 slips into a bayonet slot 18. On reversal of the handle 9 the pin 15 is tripped out of the slot 18 by a pawl 19 so that the released spring pressure on 14 and 13 ejects the apple and its core out of the machine. The pawl 19 allows the pin 15 to pass it in one direction of rotation but trips it in the opposite direction on account of its shape and pivoted mounting and its spring pressed plunger 22.

When inoperative, Fig. 5, the bars 63 are sufficiently removed from the spring extensions to allow the heads to freely accommodate themselves to the discs. The mechanism for actuating the tubes 11 to position the heads over desired tracks is detailed in Specification 1,031,276 and the aerodynamic means preventing head and disc flutter in Specification 1,031,275, which are referred to.

Abstract: 151,327. Phillips, E. A. W. June 18, 1919. Springs formed by cutting tubes.- A tubular sleeve of spring material is slitted intermediate of its ends so that under axial compression it bulges and on release of the pressure it returns to its original shape. The device is applicable as a nut-lock, as a means for securing a bolt, &c., in timber, such as a railway sleeper, as an electric coupling or contact, as a device for absorbing shocks, and for other purposes. In the arrangement shown in Figs. 2 and 5, the sleeve 1 which is provided with straight, inclined or spiral slits, is formed integral with the nut 3; upon tightening the nut, the sleeve is expanded into contact with the wall of the bolt hole. With the inclined or spirally slitted tubes the reaction may tend to tighten the nut under vibration. The slitted tube may be used in conjunction with a plain tube, another slitted tube or equivalents, and may be fitted externally with a ring &c. to limit the expansion.

Abstract: 1336615 Depositing a metal grid R C A CORPORATION 18 May 1971 [18 May 1970] 15468/71 Heading C7B A method of making a metal grid e.g. for an electron tube comprises forming a conducting film on an insulating substrate, selectively removing portions of the film e.g. by etching to form a master pattern, electro-depositing metal on the master pattern to form a grid, and stripping the deposited metal grid from the master pattern. The conducting film material is selected from Cr, Ta, W, SnO 2 , In 2 O 3  and the plating metal is one of Ni, Cu, Ag, Au and Pt. The insulating substrate may be glass or sapphire. The conducting film may be Cr 0À1 micron thick and be produced on the substrate by evaporation and cleaned in Caro's acid prior to applying a  photo-resist. A grid pattern may be produced optically and the photo-resist developed exposing squares of the conducting film. These may then be removed by sputter etching or by chemically etching with a ceric sulphate, nitric acid mixture. The master pattern so produced may be plated for 80 sec at 70 Amp/ft<SP>2</SP>. The grid may be successively washed in dionized water, methanol and acetone and then peeled off the master pattern using tweezers. For plating Ni the electrolyte may be nickel chloride, nickel sulphonate, boric acid and naphthalene disulphonic acid, the acidity being adjusted to pH 3À2-4À2 by the addition of sulphonic acid.
