Title: Protecting devices for telephone apparatus
IPC: E04C5/065
Filed: 1955-03-04
Abstract: 782,665. Protective arrangements. WESTERN ELECTRIC CO., Inc. March 4, 1955 [March 5, 1954], No. 6457/55. Class 38 (4). An excess voltage protective device for telephone apparatus comprises, connected between the lead-in conductors and earth, a composite silicon semi-conductive body having a pair of p-n junctions arranged back-to-back and provided with low resistance contacts to the p layers, the device presenting a high impedance to telephone signal voltages, but a low impedance to excessive voltages. As shown in Fig. 2, the device 20 comprises outer layers 21, 22 of p-type conductivity, resulting from a predominance of boron impurities, and an intermediate layer 23 of n-type conductivity. The p-type layers may be formed on the n-type layer by the diffusion process described in Specification 782,662, [Group XXXVI]. The layers 21, 22 are plated with rhodium 24, 25 on which is applied outer electrodes 26, 27 of tin. A lacquer coating 28 envelopes the edges of the device. A thermally-operated arrangement may effect short-circuiting of the device, to prevent damage thereto by overheating, on persistent over-voltage. Thus, the device 20 may be held within a metal cap 34, Fig. 3, by a compression spring 39 which forces an enlarged end of a contact member 36 for the device against a small lead pellet 35 within the cap, the other contact member 37 also having an enlarged head 41 against which the spring presses and which is normally clear of the lower edge of the cap. An insulating ring 40 spaces the device 20 from the inner wall of the cap. Heat developed in the device 20 by prolonged excess voltage is transmitted through contact member 36 to the pellet 35, which eventually melts, thereby allowing the device and its two contact members to be forced by the spring further into the cap until the head 41 engages the edge of the cap. The device is thereby effectively short-circuited and further heating prevented. The whole is carried by a hollow porcelain body 31. Specification 697,880 also is referred to.

Patent GB-461593-A (GB)
Title: Improvements in and relating to processes for the manufacture of foils or films of cellulose tri-acetate
IPC: B29C71/00
Filed: 1936-03-06
Abstract: <PICT:0461593/IV/1> <PICT:0461593/IV/2> An acetylation solution of cellulose tri-acetate, in which the catalyst has been neutralized immediately after completion of acetylation, is cast in an aqueous precipitating bath containing 7--20 per cent of acetic acid, and the film or foil thereby obtained is then washed and dried.  Cellulose acetates containing an acetyl content of not less than 59 per cent calculated as acetic acid are used.  Preferably the solution is subjected to stabilization before being used for film formation, in order to maintain the solution in liquid condition and avoid premature coagulation.  Stabilization may be effected by heating the solution for several hours at temperatures above 20 DEG  C. and preferably at 80--100 DEG  C. after neutralizing the catalyst.  The precipitating bath is preferably kept below 30 DEG  C.  Slit-casting apparatus may be used and the film-forming solution may contain more than 10 per cent of cellulose tri-acetate.  The film may be stretched during coagulation.  Softening agents such as triphenyl phosphates or tributyl phosphates may be added to the film-forming solution in amount up to 100 per cent of the cellulose acetate. In an example, an acetylation solution containing sulphuric acid as catalyst is treated for neutralization of the catalyst and the excess of anhydride is eliminated by addition of methylene chloride or formic acid.  The viscosity of the solution is controlled by heating to 30--50 DEG  C. during filtration, de-aeration, and casting.  The solution is extruded under pressure through a slit into a cooled coagulation bath.  After the first washing, the film is partially dried, washed again, and finally dried.  Softening agents such as glycerine, di-glycerine, and glucose, may be added to the washing baths.  The film may be washed with methyl alcohol, benzol or other organic liquid prior to the drying by heat.  As shown in Figs. 1 and 2, a film is formed by casting the cellulose ester solution from the device 10 on to roller 9 in the precipitating bath 1 containing 7--20 per cent acetic acid solution.  The precipitated film passes over rollers 11--14, then into a washing bath 2 over rollers 15--19, into a second washing bath 3, and then into a drying chamber 4 over heated drying rollers 25--31.  Regulated quantities of air are passed through chamber 4 by means of a fan.  The partially dried film then passes from roller 32 into a bath 5 in which acid brought to the film surface by the drying process is washed out, and then into a bath 6 containing water or methyl alcohol.  This bath may also contain a softening agent and dissolved pigment. The film then passes to the drying chamber 7 and finally to a frictionally driven winding device 8.  If desired, the washing liquid may flow in counter current to the film; the individual baths may be arranged one below another and connected with the precipitating bath by pipes and valves.

Title: Improvements in and relating to iodine compositions
IPC: C07K1/107
Filed: 1927-03-12
Abstract: 267,557. James, R. W., (Merck & Co.). March 12, 1927. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 14, 1927.] Medicines for internal use. - Anthelmintic iodine preparations are obtained by adsorption of free iodine by means of proteins. The iodine may be initially in the form of a colloidal suspensoid containing a protective colloid, or may be crystalline, or in solution in alcohol or in potassium iodide solution, or may be set free from a mixture of an iodide and iodate, by addition of an acid or from an iodide by means of an oxidizing agent such as chlorine gas. Suitable proteins specified are skim milk, egg albumin, blood albumin, gelatine and its derivatives, glue, and nucleinic acids. The iodine or reagents liberating iodine, are in general merely mixed with solutions of the proteins in water while stirring, but in the use of gelatine the mixture is subjected to prolonged heating to 40‹ to 50‹ to prevent gelatinization on standing. The iodine is stated to become in part chemically combined to form an iodized protein which serves as the adsorption vehicle for the remaining free iodine. The reaction mixtures may be employed as such, or the adsorption compounds may be separated by filtration and may be mixed with oil or other vehicle for use as fillings for gelatine capsules or with other excipients for use as tablets or pills. Reference is made to Specification 293,504 and to the prior use of a solution of iodine or castor oil. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the admixture of syrup with the iodine preparations and subsequent desiccating and powdering, and also preparations made by suspending a powder such as charcoal in a colloidal suspensoid of iodine. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specifications 12817/97 and 7097/98, 7740/98.

Title: Improvements in or relating to the bulk wrapping or packing of cigarette packets or other articles of similar shape and to such articles so wrapped or packed
IPC: B65B17/02
Filed: 1940-04-24
Abstract: 537,852. Packeting. MOLINS, D. W., and MOLINS MACHINE CO., Ltd. April 24, 1940, No. 7378. [Class 94 (i)] Relates to the packaging of batches of cigarette packets, or other articles of rectangular block shape for transport to the retailer. According to the invention, a number of packets or articles 1, Fig. 1, are attached to one another by means of adhesive 4 applied to their broad faces so that a composite block is formed. A band 5, Fig. 2, of material such as paper, may be wrapped around the block, or paper strips may be secured from end to end of the block without crossing the end faces. The strip may be scored or weakened in places to facilitate dividing the block. Two or more of the blocks may be attached to one another by adhesive 10 placed on the sides, or at 11 in the ends, of the articles to form a multiple block to which strips of paper may be applied. The blocks are formed by mechanism which receives packets as they leave the filling machine, or to which packets are fed from a stack. The packets 1, Fig. 7B, are carried by a chain conveyer 13 to a rotatable pocketed wheel 14, of the kind described in Specification 343,586, which delivers the packets to a horizontal shoot 15. While the packets are being fed by the conveyer 13, spots of adhesive are applied to their upper faces by rotatable discs 19. A rotating cam 22 holds the discs 19 out of action periodically to prevent adhesive from being applied to the packet which forms the front of the block. The blocks of packets formed in the shoot 15 are delivered on to a belt conveyer 25, Fig 7A, which runs at such a speed as to separate each block from the succeeding one. The leading block is delivered to a chain conveyer 26 which carries it through stripapplying mechanism. This comprises known strip-feeding and cutting devices 30, additional feed rollers 31, 32, and an oscillating gumming roller 33. The gum may also be applied in the manner described in Specification 324,171, [Class 73]. The block is next moved to a position beneath a vertical stacker or dryer 36 into which it is thrust by a vertically-reciprocating platform 37. A lip 38 on the platform folds the lower trailing edge of the strip against the edge of the block, and the other edge of the strip is folded as the block moves upwards into the stack.. If the packets are wrapped in outer covers, for example, of transparent material, they are pushed along the wrapping machine bed 42, Fig. 10, and are thrust up into a stacker or dryer 45. A reciprocating pusher 47, operated by a screw 48 in the manner described in Specification 275,276, [Class 94 (i)], pushes batches of five packets laterally on to a table 49 from the column emerging from the stacks. If paper strip are stuck to the sides of the batches, the strips may be applied by a suction roller in the manner described in Specification 305,684, [Class 73]. Thermoplastic adhesives may be used for sticking the packets together.

In the jointing of paper insulated electric power cables, the method used comprises slipping two stress cones 9 over the cut-back stepped dielectric 4 of the two single core cable lengths, jointing the inner conductors 7 by means of a ferrule 8, applying a layer of polythene tape over the whole of parts 4, 7 and 8 to form a gas-tight sealing layer 10, coating steps 3 of the dielectric 4 with viscous epoxy resin and pushing the correspondingly stepped stress cones 9 into position thereon such that some resin is extruded along the dielectric 4. A tubular mould 11, with apertures 12 and 13 uppermost, is then applied over the joint with the stress cones closing its ends and supporting it, the mould is filled with liquid, cold-setting epoxy resin 16 via aperture 12, and finally the whole joint is covered by a lapping of metal screening tape 17 which connects the cut-back screens 5 of the cables. When jointing concentric cables, a copper tube is used as the mould and is directly connected to the outer concentric conductors of each cable core (Fig. 2, not shown), the outer conductor wires being left long enough to be wrapped around the stress cones and moulded and attached thereto by a wire binding. Paper tape insulation is then applied over both the joint and the exposed ends of the outer cable dielectric, and a metal screening tape is again wound over all. Both of the above joints may be enclosed in a casing filled with insulating compound.
