Patent GB-200254-A (GB)
Title: Means for reducing the distortion in a telephone or like repeating system
IPC: H03F3/02
Filed: 1922-04-25
Abstract: 200,254. Western Electric Co., Ltd., (Western Electric Co., Inc.). April 25, 1922. Drawings to Specification. Transformers. - The input transformer of a thermionic repeater is provided with an iron core of non-uniform cross section, thereby creating a leakage flux. The inductance due to this leakage flux is of such value that, taken in conjunction with the internal capacity of the valve and the capacity of the transformer windings, resonance is established for a desired frequency. For telephone transmission, this frequency is chosen in the neighbourhood of 5000 cycles, which gives the repeater a flat gain characteristic over the important voice frequency range. The necessary leakage flux is preferably created by employing a closed transformer core, that part of the core within the superposed windings being of smaller cross section than the external portion. The core is built up of iron laminations, some of which may not be circumferentially complete.

Title: Improvements in or relating to methods of setting tacky thermoplastic adhesives to anon-tacky state
IPC: C09J7/35
Filed: 1950-05-11
Abstract: An adhesive, which becomes tacky on heating and remains so on cooling, and comprising a thermoplastic resinous material and a thermoplastic plasticizer is immediately set to a non-tacky state, after fusion and subsequent cooling to below the fusion point of the plasticizer, by distributing the same plasticizer over the cooled adhesive in finely divided solid form.  The resultant set adhesive, which may be in the form of a film on a supporting surface, may be rendered tacky again by fusing the adhesive as required and the cycle may be repeated, 3-20 per cent. added plasticizer is usually sufficient.  Adhesive compositions in examples include ethyl cellulose mixed with tri- (para-tertiary butyl phenyl) phosphate or dicyclohexyl phthalate plasticizer, and ethyl cellulose compositions having N-ethyl para-toluene sulphonamide or triphenyl phosphate plasticizer mixed with rosin, or coumarone-indene resin, or modified rosin ester and hydroabietyl alcohol.  Other compositions are polyvinyl butyral composition having N- ethyl paratoluene sulphonamide or a mixture of o- and ptoluene sulphonamide plasticizer and including polymerized rosin, or maleic alkyd-modified rosin ester and hydrogenated methyl abietate.  Powdered silica may be added to the plasticizer to prevent agglomeration.

Title: Improvements in means for inflating pneumatic tyres
IPC: B60S5/04
Filed: 1934-04-19
Abstract: 437,108. Pressure-regulating valves. TECALEMIT, Ltd., and CHALMERS, R. A., Great West Road, Brentford, Middlesex. April 19, 1934, No. 11814. [Class 135] Apparatus for inflating or deflating pneumatic tyres comprises a pressure control unit 1 with a valve 10 which regulates the air pressure from a supply pipe 23 through pipes 24, 40 to a chamber 37 between two diaphragms 34, 35 of a delivery control unit 32. Attached to one of the diaphragms 34 is a valve 52 which controls the air supply from the pipe 55 to the tyre through the pipe 47 until the tyre pressure on one side of the diaphragm 34 equals the regulated pressure in the chamber 37 on the other side, when the valve 52 will close. Attached to the other diaphragm 35 is a release valve 48 so that should the tyre pressure on the outside of the diaphragm 35 be higher than the required pressure in the chamber 37 the valve 48 will open to atmosphere to release the tyre pressure until it equals that in the chamber 37. The pressure in the diaphragm chamber 37 and hence the tyre pressure is determined by the adjustment of the spring loading 20 on a piston 18, which controls the valve 10 and which is subjected to the regulated pressure, by a manually operated cam 26 with a lever 28. The piston 18 is sealed by a diaphragm 15 and has an axial relief passage which is controlled by a valve 11 on the stem of the valve 10 so that if the regulated pressure on the diaphragm 15 is too high the piston moves away from the valve 11 and releases some of the air to atmosphere until the required pressure is obtained. A gauge 57 is provided to normally indicate the required pressure in the chamber 37 but may be connected by means of a valve 58 and a conduit 68 directly to the tyre.

Title: Improvements in or relating to methods of making hectographic copies
IPC: B41M5/025
Filed: 1959-04-08
Abstract: 883,557. Hectographic transfer paper &c. RITZERFELD, W., and RITZERFELD, G. April 8, 1959 [April 19, 1958; Sept 24, 1958 (3); Nov. 6, 1958], No. 11866/59. Class 96. [Also in Group XVI] A method of making hectographic copies from a printing master sheet prepared photomechanically or by inscribing and having printing image areas which comprise a non- staining or only slightly staining leuco dye compound, comprises, prior to the printing process, converting the leuco compound into its alcohol or water-soluble heavily coloured dye salt by the action of an acid, subjecting it to an oxidization process before, with or after the acid treatment and duplicating on to copy sheets moistened with a neutral-reacting copying liquid forming a solvent for the dye salt. Leuco compounds of a triphenyl-methane dye may be used. On photo-mechanically prepared master sheets, the leuco compound and optionally the oxidation medium are contained in a gelatin layer containing a silver halide. An example of a developing liquid is: water 1000 c.c., pyrochatecol 15 gms., sodium sulphite 1.5 gms., potassium carbonate 60 gms., further diluted 1 to 3 in water. In the case of inscribed master sheets, parts of a layer of fat, waxes, leuco compound and oxidation medium is transferred by hand or typewriter pressure to the master sheet from a transfer sheet in contact therewith. The transfer layer may comprise leuco base of methyl violet 50 parts, barium peroxide, potassium dichromate or sodium peroxide 5 parts; petroleum jelly 35 parts; carnauba wax 10 parts. The leuco base of malachite green may be used. The acid, e.g. formic acid may be applied as a vapour, or as a liquid, such as a 20% aqueous solution of hydroxy carbolic acid (glycolic acid or lactic acid) with 4% of formic acid, a 50% solution of acetic acid with 4% of formic acid, a 5% solution of formic acid, or acid-reacting substances, such as saturated aqueous solution of substituted phenols, aromatic carboxyl acid or naphthols, e.g. p-nitrophenol, picric acid, salicylic acid, or α-nitronaphthol, to which substances may be added, e.g. formic acid, acetic acid, salicyclic acid, lactic acid, hydrochloric acid, phosphoric acid, nitric acid, sulphuric acid or glycolic acid; or as a solid, in a watersoluble binder in a colloid or methyl cellulose as a layer on a contact sheet, e.g. amino acid and manganese dioxide or lead dioxide suspended in gum arabic, polyvinyl alcohols or methyl cellulose, the oxidizing substance in this case being contained in the same layer. Otherwise the oxidizing substances may be applied in a bath, e.g. water 1,000 c.c., permanganate 30 gm., potassium dichromate 30 gm. ; oxidizing substances which avoid discolouring the master sheet are, e.g. benzoyl peroxide. The copying liquid is alcohol, water or a mixture thereof, to which a higher valency alcohol may be added to increase the dissolving power.
