Title: Luminous tuning dial for receivers
IPC: H03J1/02
Filed: 1973-02-20
Abstract: 1426562 Illuminated displays AUTOVOX SpA 20 Feb 1973 [21 Feb 1972] 8219/73 Heading G5C [Also in Division H3] In a luminous tuning dial for a receiver having an electronic tuning system which is responsive to variations in the level of a tuning control signal, the dial includes an array of lamps 102a, 102b, 102c, Fig. 2, in parallel circuits, and electronic switches 110a, 110b for the lamps, each electronic switch is connected between a power supply line 109 and one terminal of its associated lamp, threshold switches 106a, 106b, 106c for the lamps, are commonly connected to a conductor 107 for carrying the tuning control signal and are responsive to discrete levels of the tuning control signal to energize lamps sequentially from an end of the array in response to a variation in the level of the tuning control signal, and each threshold switch, except the one 106a associated with the lamp at the end of the array, providing a signal to the control input terminal 110a<SP>1</SP>, 110b<SP>1</SP> of the electronic switch connected with the previously energized lamp to deenergize that lamp. The tuning dial may be used in receivers where variable reactance elements such as variable capacity diodes, are driven by the variations of level of a sawtooth tuning control signal, in a cyclically repeated scanning of a given frequency range and the scanning cycle is stopped when a transmitter of sufficient intensity is tuned in. During each scanning cycle the lamps 102 will momentarily light in succession until the lamp which remains alight indicates the frequency at which the scanning is stopped. The lamps 102 are arranged in compartments (104, Fig. 1, not shown) covered by light transparent plates (105<SP>1</SP>) which indicate the tuning frequency.

Title: Chemically embossed surface covering and method of making same
IPC: D06N7/00
Filed: 1973-02-20
Abstract: 1429943 Embossed surface covering ARMSTRONG CORK CO 20 Feb 1973 [22 Feb 1972] 8371/73 Addition to 1150902 Heading B2E [Also in Divisions B6 and C3] The process of specification 1150902 is modified in that after the application of the catalyst containing composition the sheet is preheated to such a temperature and for such a time as to achieve substantial completion of the polymerisation reaction in the areas where the composition has been applied without causing decomposition of the blowing agent and after the heat of reaction has been dissipated, the sheet is reheated to a temperature sufficient to fuse the resin, to polymerise at least some of the monomer in the remaining areas and to decompose at least some of the blowing agent. The pre-heating may be at 260-300‹F for 50-70 seconds, the dissipation of reaction heat may be at 70-90‹F and the final heating may be at 320-360‹F for 40-90 seconds. In a preferred embodiment, after application of the catalystcontaining composition a coating of a clear plastisol is applied to the surface of the printed gelled plastisol and the clear coated sheet is heated to gel the clear coat, and, if desired, at least partially polymerise the monomer in the printed areas. Decorative chips are then applied over the gelled clear coat and the material re-heated to soften the coat and chips so that the chips adhere to the coat and, if necessary, to complete polymerisation of the monomer. The chip-covered sheet may be roll-coated with a clear plastisol and the coating levelled with a doctor blade. The main polymeric material of the various plastisols, the thermoplastic sheet and the decorative chips may 'be p.v.c. The chips may be of the same material as the clear gelled layer except that they are pigmented. Other materials suitable for the sheet are vinyl chloride copolymerised with vinylidene chloride, vinyl acetate, propionate or butyrate, alkyl substituted vinyl esters, or acrylic monomers, or polymers of styrene, substituted styrenes, acrylic or methacrylic acid, alkyl acrylates or alkyl methacrylates. The sheet may be doctored or roll coated onto a strippable temporary carrier or a permanent backing, e.g. rubberbonded asbestos, vinyl sheet or cellulosic felt.

IPC: B01D46/02
Filed: 1922-03-23
Abstract: 196,457. Oddie, W. M. March 23, 1922. Filtering air.-In apparatus in which dust laden air is fed tangentially to a chamber above an arrangement of filter tubes, the air is by-passed through a separate filter unit at one corner of the filter proper while the main filters are being cleaned. The filter nozzles and the hopper securing means are also modified. A set of sleeve filters A, Fig. 1, communicating with a common receiving chamber A<1>. The air may be by-passed at C into a single tube D while the set of tubes is cleaned, thus maintaining the continuity of the filtering operation. The nozzles E, forming the communicating means between the sleeves and the chamber A', project into the sleeves so that the air passes some distance down the sleeves before impinging against the walls, thus losing some of its initial velocity and obviating the tendency to force dust through the walls of the filter. The dust-collecting bag is secured to the hopper by a fitting shown in Fig. 5, comprising a damper F and two connecting rings. The ring F<1> which secures the fitting to the hopper is smaller in diameter than the ring F<2> to which the bag is secured. The damper is closed when the bag is removed.

Abstract: Bis-(alkoxy aryl) disulphides, in which the alkoxy group may be saturated or unsaturated and the aryl group may have a benzene or naphthalene nucleus and may be substituted or unsubstituted, are prepared by alkylating phenolic disulphides.  The Specification describes the preparation of dithiobis (methoxy-toluene), dithiobis (ethoxytoluene) and dithiobis (allyloxytoluene) by reacting dicresyl disulphide with methyl sulphate, ethyl iodide and allyl bromide respectively.ALSO:Vulcanized rubber scrap from natural rubber, polymers of butadienes 1 - 3, and copolymers of butadienes 1 - 3 with compounds which contain a CH2 = C < group, is reclaimed by heating in the presence of a bis (alkoxy aryl) disulphide, preferably a dithio bis (alkoxytoluene) such as dithio bis (methoxytoluene), dithio bis (ethoxytoluene) or dithio bis (allyloxytoluene), for a time sufficient to soften the scrap to a workable condition.  The amount of bis (alkoxy aryl) disulphide may vary from 0.05 to 6 per cent by weight of the scrap, more being required for synthetic than natural rubber, and the disulphides may be used in conjunction with oils such as dipentene which are normally used in reclaiming.  The process preferably takes place at a temperature of at least 300 DEG  F, the Specification containing examples describing the treatment of natural rubber, butadiene-styrene copolymer and neoprene in a heater under live steam pressure at 365 DEG  F for 16 hours in the presence of small amounts of bis (alkoxy aryl) disulphides and reclaiming oils.

Abstract: 1,129,467. Semi-conductor photo-responsive circuit. RADIO CORPORATION OF AMERICA. March 1, 1966 [March 15, 1965], No.8860/66. Heading G1A. [Also in Division H3] During periods of high light intensity the voltage across the reverse biased photo-diode CR1, which may instead be a photo-transistor or duodiode in series with its load impedance R 1,  would fall almost to zero causing the diode to saturate if not for the clamping diode CR2 whose reference voltage V 3  is between the biasing voltages V 1  and V 2 . The clamping diode is arranged to become forward biased at a predetermined light intensity. During a dark state little current flows through the photo-diode and the potential at junction 1 saturates transistor Q 1  but at the predetermined light intensity the transistor is almost turned off and the output V o  falls from its value of almost V 4  at saturation to almost V 3 .
