Title: Improvements in coin-freed shooting apparatus
IPC: G07F17/38
Filed: 1928-10-08
Abstract: 323,793. Finkelstein, A. Oct. 8, 1928. Shooting-apparatus.-The apparatus comprises two rifles G, H, Fig. 1, of the spring-gun type, placed side by side, each adapted to be loaded and used by a separate competitor on a separate target, the coin-controlled mechanism and the mechanism for returning the parts to normal position being operated by interconnected mechanism extending laterally between the two rifles. The rifle H has similar mechanism to the rifle G which is mounted for movement in all directions and is provided with sights on a dummy rifle g, Fig. 2, When a rod G<14> is pulled after the insertion of two coins, a block G<5> fixed to a sliding rod G<7> compresses a spring G<4> and a trigger catch G<21> retains the rod until the trigger G<17> releases it. A striker G<9> carried by an extension of the rod G<7> hits, when the rifle is correctly sighted, one of four rods T<1>, thereby moving a catch 12 and allowing a rod 11 to drop. The rod 11 is attached to a disappearing object on the head of a target figure 10. There are four figures in each target and the competitor who first causes the four objects of his target to disappear has his coin returned. The block G<5> is normally locked against movement by a stop pin G<19> extending into its path. Coin action, weight; returning coin. - The first coin inserted in a shoot C, Fig. 1, falls to two arms 2, 3 and tilts a diverting arm C' to pass the second coin to a shoot C<8> where it tilts an arm 4, the end of which normallv engages a stop 4c. This frees a shaft 4d which is rotated by a handle A and through linkages withdraws the stop-pins G<19>, H<19> of the rifles. When all the catches 12 of one target are hit, four rods 14 connected thereto are moved to withdraw one or other of the two arms 2, 3, allowing the first coin to be delivered to the successful competitor. This coin in falling tilts a catch 21 to free a shaft 23 which is then rotated by a knob B to return the targets to normal position. An arm 20d on the shaft operates a slide 20, which releases catches 40 holding the stop-pins G<19>, H<19> out of action.

Title: Laminate
IPC: B32B27/00
Filed: 1966-06-29
Abstract: 1,112,463. Laminates. GENERAL ELECTRIC CO. 29 June, 1966 [12 July, 1965], No. 29281/66. Heading B5N. A laminate comprises a resin impregnated core stock and a surface layer comprising glass fibre paper impregnated with a resinous composition comprising by weight 70 parts of a phenolic resin modified epoxy resin, up to 50 parts of a thermoplastic condensation polymer of an epihalohydrin, and a polyhydric alcohol or polyhydric phenol, and from 0À1 part to 3 parts tertiary amine or a compound capable of liberating a tertiary amine upon heating. The core stock may be kraft or other paper or cellulosic, synthetic or organic materials either alone or in combination, and is for example fabric composed of glass, rayon, polyethylene terephthalate, acrylic, or asbestos fibres alone or in combination, e.g. eellulosic paper reinforced with glass fibres. The surface layer is a glass fibre paper, the fibres of which may be sized with silicones or chromium containing materials. The tertiary amine, which acts as a curing catalyst is of the formula R 3 N, where R is a monovalent hydrocarbon radical, e.g. an alkyl, aryl, aralkyl, alkenyl, cycloalkyl or cycloalkenyl radical and many examples of suitable amines are given. Alternatively, the term " tertiary amine" also includes amine derivatives, e.g. salts, and quaternary ammonium bases of amines. In one example, the core stock comprises six plies of fibre-reinforced α- cellulose paper impregnated with a 50% solution of phenol-formaldehyde resin and dried in an oven. The surface layer is one ply of glass fibre paper impregnated with a solution comprising 70 parts phenolic modified epoxy resin, 30 parts of phenoxy resin which is a copolymer of bisphenol-A and epichlorohydrin, and 0À7 part of amine in a solvent. The solution is applied by dipping, brushing, or roller coating, and is dried by heat. The core and surface layers are assembled under heat and pressure which causes curing of the resins. The resulting laminate may be plated with a metal, e.g. copper, to produce a printed circuit board. The adhesion of the metal to the copper may be improved by heat treatment.

Title: Production of non-acidic hydrogen peroxide solutions
Inventor: CAMPBELL JOHN STEWART
IPC: C01B15/013
Filed: 1963-07-24
Abstract: Amide hydrogen peroxide adducts, e.g CO(NH2).H2O2 are prepared by the action of H2O2 and O2 in an aqueous acidic reaction medium in the presence of a solid catalyst as described in Specification 1,041,045, adding a precipitant for the acid used, filtering and then adding the amide (say 5% excess) to the resulting solution and evaporating to dryness. Alternatively the urea may be present during the formation of the H2O2.  The adducts may be used in the oxidation of olefines. The non-acidic solutions of H2O2 produced as above may be reacted to produce substituted hydroxylamines from primary or secondary amines, oximes from primary amines and amine oxides from tertiary amines. Sequestering agents may be present during the latter reaction. Examples describe the production of cyclohexylamine hydrogon peroxide adduct and its conversion to N-cyclohexyl hydroxylamine, and the oxidation of cyclohexylamine to give a cyclohexylamine-cyclohexanone oxime adduct from which cyclohexanone oxime is isolated, the cyclohexylamine being recovered as its sulphate.ALSO:Non-acidic H2O2 solutions are prepared by addition of a precipitant for the acid used in the preparation of H2O2 by the reaction of H2 and O2 in an aqueous acidic reaction medium in the presence of a solid catalyst as described in Specification 1,041,045.  The precipitant is a substance which forms with the acid present a compound of low solubility in the solution and is itself of low solubility therein, e.g. the carbonate or hydroxide of Ca, Sr, Ba, Pb, Na or K or an ion-exchange resin. Preferably a non-acidic oxygen-containing organic compound is present, e.g. acetone, preferably forming at least 20% by volume of the solvent at precipitation.  An H2O2 stabilizer as defined in Specification 1,056,121 may be present. The non-acidic solution may be reacted with an amide to form an amide hydrogen peroxide adduct. The amide is preferably soluble in the solvent medium, e.g. urea when aqueous acetone is the solvent.  H2O2 of low water content may be produced by the reaction of such an adduct with a non-aqueous liquid which dissolves H2O2 preferentially to the amide, e.g. by adding anhydrous acetone to the anhydrous urea hydrogen peroxide adduct and filtering.

Title: Image formation system with scanning drop generators
IPC: B41J2/21
Filed: 1969-06-10
Abstract: 1277234 Facsimile recorder MEAD CORP 19 June 1969 [18 Oct 1968] 29397/69 Heading H4F A liquid drop facsimile recorder comprises one or more drop generators arranged to scan across a plane recording member in successive arcuate paths, linear movement of the recording member providing the slow scan component. In the embodiment described, four photo-electric scanners are mounted on a rotating disc and arranged to successively scan in arcuate paths an original which is slowly moved parallel to the plane of the disc. The resulting video signals which are sequentially representative of magenta, cyan, yellow and black are then passed via a threshold logic circuit to a circuit in which they are sampled to produce pulsed signals indicative of the presence or absence of appropriate dots in the print to be reproduced by the facsimile recorder which comprises a similar arrangement of four liquid drop generators mounted on a rotating disc. The drop generators are preferably inclined in a rearward direction with respect to the rotational direction of the disc so that the drops are projected with a horizontal velocity component which effectively cancels the velocity produced by the disc rotation so that the printed dots have a generally circular configuration.

Abstract: 1348865 Measuring relative humidity electrically HONEYWELL Inc 23 June 1972 [23 June 1971 (2)] 29528/72 Heading G1N A method of producing a relative humidity detector comprises forming electrodes 11, 12 on a quartz substrate, coating the substrate with a mixture of metal oxide and binder, firing to drive off the binder and produce a coherent porous oxide layer, and treating this layer to reduce the electrical resistance thereof. Two different treatments are disclosed. The first comprises wetting the layer with a salt solution, e.g. FeCl 3  solution, to provide chloride ions and then firing to convert part of the oxide layer into an oxychloride. The second comprises impregnating the layer with a humectant material having reversible absorption properties, such as polyethylene glycol or a hygroscopic glycol. After this treatment the detector may be stabilized by subjecting it to cycles in which the humidity is increased and then decreased. A coating of a moisture permeable membrane (e.g. p.v.a.) may be provided for protection. The device may be calibrated using an A. C. impedance bridge, and the resistance values measured on a meter or chart recorder. Fig. 2 (not shown) compares resistance/humidity curves of treated (A) and untreated (B) elements. Calibration should be at a frequency comparable with that subsequently to be used. The electrode 11, 12 may be gold, palladium or platinum and formed by conventional methods. The metal oxide is preferably from Group VIII, particularly Fe 2 O 3 , Ni 2 O 3  and NiO, and the binder may be polyvinyl alcohol.

Title: Improvements in or relating to refractor members for use in lighting fittings for street lighting and like purposes
Inventor: BEGGS STANLEY SUTTON
IPC: F21V5/00
Filed: 1961-08-17
Abstract: 942,608. Refractors for lighting fittings. GENERAL ELECTRIC CO. Ltd. Aug. 28, 1962 [Aug. 17, 1961], No. 29721/61. Addition to 837,607. Heading F4R. In a refractor member for street lighting fittings having four sets of prisms extending in radial planes each set in a different one of four quadrants formed by two perpendicular radial planes, as described in Specification 818,401, the prisms are designed so that in each set the tip angle P is either the same for all prisms of the set or has the same value P for all prisms within the angle A between the central plane and the preferred radial plane, i.e. the plane about which the prisms are designed to concentrate the light, and a different value Pc in the complementary region of axle 90 degrees-A, the prisms being so orientated that the angle T which the internal bisector of the tip angle makes with the radial plane through the centre of the base of the prism is related to the angle A and to the angle # between the said radial plane and the central plane is substantially in accordance with the formula where A is A or 90 degrees-A, # is # or 90 degrees-# and P is P or Pc according to whether the prism lies inside or outside the angle A, the sense of the angle T being such that the tip of the prism lies between the said radial plane and the preferred radial plane for the set. Preferably natively P and Pc may be equal and have a value lying between these preferred values. The arrangement of prisms is similar to that in the parent Specification except in the areas MON and M<SP>1</SP>ON<SP>1</SP> where the different angles of inclination render the refractor suitable for use with light sources of relatively large size. In making a mould for producing the refractor a cutting tool of tip angle P or two cutting tools of tip angles P and Pc are used, the tools being held at progressively changing inclinations, during cutting of successive recesses so that the angle T<SP>1</SP> which the internal bisector of the tool tip makes with the radial plane through the centre of the element of surface to be cut is related to the angle A of the final refractor member and the angle #<SP>1</SP> between the element centre radial plane and the central plane by a formula similar to that for the prisms. The refractor may be in the form of a bowl with frusto-conical sides and a rounded base provided with prisms as described in Specification 911,984.
