Filed: 1949-07-12
Abstract: 666,017. Party line systems. GENERAL ELECTRIC CO., Ltd., and FORBES, W. A. May 19, 1950 [July 12, 1949], No. 18388/49. Class 40 (iv). In a party line system suitable for railway working where the line normally carries no direct current an extension line may be coupled to a main line as required and an alternating current signal is applied automatically to the main line to decouple the extension line on completion of a conversation. As shown, operation of the speak key SK brings up D to connect the operator to the main line and the operator may then dial a wanted party on the main line. If he wishes to couple the extension line a special digit is dialled to operate relay F (of which only contact f1 is shown) thereby bringing up H which locks and couples up the extension line. The required station thereon is then rung by dialling a code of long and short digits-to cause the dialling relay C to connect up long and short bursts of battery to ring all the bells on the extension line. On termination of the call restoration of the speak key connects alternating current over the earth phantom during the release period of D and this brings up U to open locking-circuit of the coupling relay H.

Abstract: 1364163 Press brakes VERSON ALLSTEEL PRESS CO 20 April 1972 [3 May 1971] 18396/72 Heading B3E [Also in Division B5] A press comprises a brake; fast and slow clutches; and a control system having a first switch operable at a predetermined point in a cycle of operation of the press to disengage the fast clutch and to engage the brake a second switch operable to engage the slow clutch and to disengage the brake and means adapted to sense the states of the fast and slow speed clutches for controlling the operation of the press in case of malfunction. In the operation of a mechanically actuated press brake, a solenoid 44, Fig. 2, is energized to supply hydraulic fluid via a valve 42 to a line 52 and, simultaneously, solenoids 72 and 64 are energized to supply the hydraulic fluid, via a valve 70, line 80 and flow control device 82, to the fast clutch 84. The ram 14 of the press brake is thus driven downwardly at a rapid speed. When limit switches 24, 26 are energized by the ram 14 the valves are switched to disengage the fast clutch and to engage the brake 58. Subsequently the solenoid 72 is de-energized to change the position of the valve 70 so that fluid is supplied, via fluid control device 76, to the slow clutch 78. The ram is thus driven at a slow speed, until it reaches its lowest position where a limit switch is actuated to operate the solenoid 72 in order to energize clutch 84 to return the ram at a rapid speed. An electric control circuit (Fig. 3, not shown) is described for detecting the operational states of the valves so as to provide a control of the brake and clutches in case of malfunctions.

Title: Elastomeric polyesterurethanes
IPC: C08G18/84
Filed: 1953-07-08
Abstract: A rubbery polyesterurethane gum is made by reacting a mixture of (a) 1 mol. of a linear polyester containing a preponderance of terminal hydroxyl groups and preferably of molecular weight 400-3000; (b) 0.2-1 mol. of water; and (c) 1-2 mols. of an organic diisocyanate. Preferably the molar quantity of diisocyanate is approximately equal to the sum of the molar quantities of water and polyester.  Instead of water there may be used substances liberating water, e.g. salts containing water of crystallization, materials containing absorbed water, e.g. clay or silica gel or materials decomposing to liberate water, e.g. boric acid.  The Specification lists suitable polyester forming reactants, diisocyanates and salts containing water of crystallization.  The rubbery gum may be cured by milling it at 170-250 DEG  F. with a polyisocyanate (many specified), formaldehyde, a formaldehyde liberating substance or a formaldehyde-amine condensation product and heating the mixture to about 275 DEG  F. under pressure.  If a diisocyanate is used as curing agent, the number of mols. used is preferably equal to or slightly in excess of (2 x mols. of water) + (the mols. of polyester) - (the mols. of diisocyanate used in the gum formation).  In examples (1) and (2) hydroxy polyethylene adipate (M.W. 600-1200) is mixed with water at 50-60 DEG  C., p-phenylene diisocyanate added, the mixture heated to 110 DEG  C., and the mixture poured into a wax-coated container and heated to 135 DEG  C. to produce a gum; (4) the gum of examples (1) and (2) is vulcanized by heating with p-phenylene diisocyanate at 280 DEG  F. under pressure; (5)-(10) the gum of examples (1) and (2) is vulcanized by heating with naphthylene-1,5-diisocyanate at 298 DEG C.; (10) a gum is made by reacting hydroxy polyethylene adipate, p-phenylene diisocyanate and water in the form of Na2SiO3.9H2O, H3BO3 or K2Al2 (SO4)4.  24H2O.  The gum is vulcanized by heating it with p-phenylene diisocyanate.

Title: Improved process for the manufacture of decorative sheet material
IPC: C09D101/18
Filed: 1928-06-29
Abstract: 293,391. Soc. des Brevets J. Paisseau. July 5, 1927, [Convention date]. Ornamenting.-Ce11u1oid or other sheet material having a cellulose ester as a base is coated with a cold composition comprising a substance similar to that of which the sheet is made, colouring- matter such as a coloured powder, a metallic compound, a lake co1oured by aniline dyes, or a white pigment and a solution of an aniline colour, a solvent for the celluloid &c., and a volatile liquid serving as a diluent and mixed in such proportions relative to the solvent that the sheet is neither dissolved nor distorted. As an example, a composition for backing sheet material made from ce11u1ose acetate comprises cellulose acetate, a pigment, ethyl lactate, and ethyl acetate as solvents, and methyl alcohol as a diluent. Acetone, methyl acetate, and diacetate of glycol are also suitab1e, as solvents, and ethyl alcohol and crystallizable benzene as diluents. Where the sheet has a nitrocellulose base, celluloid is substituted for ce11u1ose acetate, amyl or butyl acetate, acetone, or cyc1ohexona1 may be employed as solvents, and alcohol or benzene as di1uents. The coated surface may be polished by applying heat and pressure, patterns may be produced by using stencils, and two coats of composition of contrasting colours may be applied in succession. Special ornamental effects may also be produced by applying to the back of the sheet a coating which contains more pigment than binding material and therefore shrinks and forms sets of cracks on drying, and then a second coating of dark or black composition. The coated sheet may be fixed to a thick sheet to form compound sheet material by coating both with a solvent and applying heat and pressure. By fixing a sheet of paper to the coated sheet, material suitable for making boxes may be made, and by fixing thin sheets of wood, material for use as veneer in cabinet-making or for marquetry may be produced; alternatively, fabric of natural fibres or artificia1 silk fabric, 1oaded, if desired, with pearl essence, may be fixed to the coated sheet.

[Class 141] Guide means for facilitating the correct positioning of the seam lines when marking out material which is to be cut out and made up into garments, comprise a strip of flat tape or the like having one or more ridged portions on its upper face which act as a guide for a chalk or other marking device. The tape 4 is preferably provided with an adhesive undersurface, and may have two parallel ridges 5 formed thereon by pressing the tape down on to two cords 7. The tape may be applied to a dressmaker's dummy figure or to a garment form to set out the seam lines for a garment, the material being applied over the ridges, and the seam lines indicated by means of a piece of grooved chalk. In a modification, the groove between the ridges may be chalked or pigmented, and the material of the garment laid thereon, and pressed into the groove by means of a suitable tool. In a further modification, the material may be applied adjacent to the ridges but not covering the same, the ridges serving as a guide upon which a suitable marking device can be moved to mark lines parallel to the ridges. The ridged tape may be applied to the human figure, or made into a skeleton garment, and then applied either to the human figure or to a lay figure. In the case of a lay figure, instead of using a ridged tape, the seam lines may be marked on the figure by means of parallel cords or the like spaced apart to form a groove which is then chalked or pigmented.
