Abstract: 747,629. Printed circuits; couplings. PHILCO CORPORATION. July 16, 1953 [July 17, 1952], No. 19760/53. Classes 36 and 38 (1). A printed circuit comprises an insulating base 10 having conductive paths 19 thereon made of material which has no affinity for a given solder and which are electrically connected to terminals 18, which may overlie the ends of the paths 19, made of a conductive material which has an affinity for the solder. The circuit may be made from a panel comprising the base 10 clad with a laminated foil consisting of an inner layer of aluminium and an outer layer of copper. The terminals 18 are marked on the copper in an acid-resistant ink and the assembly etched in a medium such as dilute nitric or acetic acid to remove the exposed portion of the copper but not the underlying aluminium. The conductor pattern is then marked on the thus exposed aluminium layer in an acid-resistant ink and the exposed portions of the aluminium etched away with, for example, a mixture of sulphuric and hydrochloric acids. The ink covering the thusformed terminals 18 and conducters 19 is removed with a solvent such as turpentine or benzine. The assembly is then perforated adjacent each terminal as at 14 and circuit components 11 mounted on the plain side of the base 10 with their leads 13 protruding through the perforations 4. The panel is dipped in a fluxing solution and then into a molten lead-tin alloy solder bath, at least to a depth such that solder 21 adheres to the copper terminals 18 and the ends of the leads 13. Reference has been directed by the Comptroller to Specification 639,178.

Filed: 1929-06-27
Abstract: 336,237. I. G. Farbenisdustrie Akt.- Ges. Nov. 16, 1928, [Convention date]. Ester condensation products; chlorine derivatives.-In the manufacture of condensation products from vinyl esters, or of lacquers therefrom, there is added before, during, or after polymerization of the esters a small proportion of a basic substance soluble in organic solvents. The resin is thus rendered non-corrosive and is stabilized to light and heat. Suitable basic substances are guanidine and derivatives thereof, hydrazine and derivatives thereof, dimethylaniline, condensation products of amines such as ethylamine and aldehydes such as formaldehyde; phenylhydrazones, and mixtures of such compounds ; examples show the use of diphenyl guanidine, cyclohexylamine, hexamethylene tetramine, dimethylaniline, and phenylhydrazine. A nitrogen compound having plasticizing properties, for instance a condensation product of urea and formaldehyde or a polyvalent alcohol, may be employed in addition. The basic substance may be fused with the polymerized vinyl ester, or be mixed with a lacquer prepared from the resin; it is added in quantity sufficient to produce neutrality. The examples relate to polymerization products of vinyl acetate, chloracetate, chloride, and benzoate; in the polymerization of the lastnamed benzoyl peroxide is added as well as phenylhydrazine. In the production of lacquers, the vinyl chloracetate resin is dissolved in acetone, with the addition of cyclohexylamine, and the vinyl chloride resin in chlorbenzene and cyclohexanone, with the addition of small amounts of a soluble urea-formaldehyde condensation product and of dimethylaniline.

Filed: 1956-06-28
Abstract: Wool and wool-containing fabrics are treated with an aqueous solution containing permonosulphuric acid or salts thereof and a permanganate at a pH below 11 in order to reduce their felting and shrinking tendencies.  The process may be carried out batchwise in dilute solutions of the reagents containing approximately 0,05% by weight, or continuously with more concentrated solutions containing 0,4% by weight or more of the reagents, which may be mixed together in a single bath or applied consecutively by passing the material first through the permanganate bath and then through the permonosulphuric bath. The wool or fabric may subsequently be treated with an aqueous solution of a bleaching agent, such as sulphurous acid or a salt thereof in the presence of formic acid, or hydrogen peroxide.  The treatment is preferably carried out at temperatures between 10 DEG and 40 DEG C.  The Provisional Specification states that the permanganate treatment may follow the permonosulphuric acid treatment.

Title: Improvements in apparatus for opening and closing bulkhead doors of vessels
IPC: B63B19/00
Filed: 1928-07-10
Abstract: 293,762. Atlas-Werke Akt.-Ges. July 11, 1927, [Convention date]. Operating doors hydraulically.-For opening and closing bulkhead doors from a central control station and locally by means of pressure fluid by an arrangement comprising a floating piston 10 in a cylinder 9 which is connected by its middle part to a door-operating cylinder 12 and is mounted on the pipe line near the bulkhead door, one end of the cylinder 9 is directly connected to the door-closing pipe 6 and the other end directly to a four-way valve 16 which, in turn, is connected directly to the door-operating cylinder 12, to the door-opening pipe 4 and to a discharge water pipe 7. The arrangement provides that individual doors may be closed locally but may be opened only from the central control station. Pressure liquid is supplied from a reservoir 1 through a pipe 2 to a four-way valve 3 at the central control station. As shown, this valve is set for opening the doors by pressure fluid supplied through the pipe 4. Pressure fluid passes through the valve 16 and pipe 18, Fig. 2, to the underside of the piston 13 connected to the door 5, and exhaust fluid passes through the pipe 11, cylinder 9. pipe 15, and valve 16 to the pipe 7, which leads to the tank 8. To close a door locally, the lever 17 of the four-way valve 16 is moved into the position shown in Fig. 1, when pressure fluid from the pipe 4 passes through the valve 15 to the cylinder 9 to the pipe 11, which leads to the upper side of the piston 13, exhaust fluid from the pipe 18 passing through the valve 16 to the pipe 7. When the valve 3 is moved into a position for " bulkheads closed " the pipe 2 is connected to the pipe 6, and the floating-piston 9 is moved to the right to admit pressure fluid through the pipe 11, exhaust fluid passing through the pipe 18, valve 16 to the pipe 4, which communicates through the valve 3 with the pipe 7 and tank 8. Movement of the handle 17 from the upper to the lower position places the exhaust pipe 18 in direct communication with the pipe 7, the closing movement of the door being unaffected.

Abstract: 224,292. Parsons, Sir C. A., Cook, S. S., and Kimber, H. G. Aug. 8, 1923. Starting. - Steam is admitted to an internalcombustion engine cylinder by a valve E brought into operation by a single device which also brings into operation means for reducing the compression in the cylinder, either by restricting the flow of air to the air valve A or by delaying the closing of the air valve. As shown in Fig. 1, the steam valve E is actuated by a cam I and a lever F pivoted upon an eccentric G adjusted by means of a lever K through members L, M, N. The lever K is also connected by a link O to a throttle valve Q for restricting the air supply to the valve A. The throttle Q may be provided with a bye-pass to regulate the quantity of air admitted. In a modification, the compression pressure is temporarily reduced by discharging all or a part of the air charge before the end of the compression stroke, the air-valve lever being mounted on an eccentric and actuated by a cam shaped to delay the closing of the air valve during starting, or to prevent the opening of the air valve before or during the compression stroke.
