Title: Manufacture of patterned pilous materials
Inventor: LANE FREDERICK HENRY
IPC: D04H11/00
Filed: 1950-11-16
Abstract: 687,982. Patterned pile fabrics. DUNLOP RUBBER CO., Ltd. Sept. 24, 1951. [Nov. 16, 1950] No. 28014/50. Class 140. [Also in Group IX] Pilous material, e.g. suedette, havingapattern, e.g. lines, formed of areas with pile separated by areas without pile is produced by applying a heat-settable adhesive to one side of a sheet backing material, e.g. plasticised polyvinyl composition, or woven fabric such as gaberdine, indiana or wigan sheeting, rendering the adhesive ineffective over those portions of the surface where no pile is required by applying a hot embossed roller to the adhesive or to the uncoated side of the backing to set the adhesive over those portions, distributing fibres over the coated surface, and anchoring the fibres deposited on the, still effective adhesive by heating to set it. Suitable adhesives are oil modified phenol-aldehyde resins or heat gellable pastes of finely divided polyvinyl compound, e.g. polyvinyl chloride or a copolymer of vinyl chloride with vinylidene chloride and/or vinyl acetate, dispersed in a liquid plasticiser, e.g. dibutyl phthalate or tricresyl phosphate, which are rendered non-adhesive at above 100‹C. and gelled at 120-170‹C. Loose fibres may be removed from the first set adhesive portion by vibration or brushing. The fibres may be distributed by passing the material, adhesive coated surface down, above a conveyer carrying short rayon fibres, through an electrostatic field.

Title: Improvements in or relating to the production of chlorine dioxide
IPC: C01B11/02
Filed: 1949-11-02
Abstract: Chlorine dioxide is prepared by producing a mixture containing chloric acid and a peroxidized compound selected from the group consisting of perborates, percarborates, pertitanates, pervanadates, perzirconates, the corresponding acids and acid anhydrides and benzoyl peroxide, or mixtures of these materials and maintaining the mixture at a temperature of 30-60 DEG C.  A stream of inert gas may be passed into the mixture to remove the chlorine dioxide as it is formed.  Compounds of titanium, vanadium and zirconium may be oxidized to peracids by other per-compounds and after the reaction to produce chlorine dioxide may be regenerated by further action of the per-compounds.  Such per-compounds are perborates, perboric acid, persulphates, and hydrogen peroxide. The chloric acid may be formed in situ from sodium chlorate and dilute sulphuric acid.  Continuous operation may be secured by regular addition of the reactants to the reaction vessel and regular removal of the reaction products.

An indicator responding to the closing of a pair of contacts upon a liquid level attaining a predetermined value, for example in the filling of an oil tank, comprises a relay winding 3 connected in parallel with a lamp 6 and a bell or buzzer 2 connected to a storage battery 1 through a normally-closed contact 7 of the relay. The liquid-level-sensitive circuit including the contacts to which the circuit responds has a plug which when plugged into receptacle 5 connects the contacts across terminals 8, 9. The contacts are normally closed so that when main switch 4 is closed lamp 6 lights and audible indicator 2 operates for a short interval before relay 3 operates to open switch 7. Thereafter the audible indicator 2 remains silent until the controlling contacts open, the indicator 2 then sounding and the lamp 6 being extinguished. The socket 5 may also be used to supply charging current to the battery 1. The bell or buzzer 2 may be replaced by an electrically operated siren.

Title: Magnetic record apparatus

Abstract: 1393613 Recording and playback MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 16 June 1972 [16 June 1971 (2)] 28433/72 Heading G5R In a juke box, a desired cartridge/cassette in the store is operated by comparing a voltage which indicates the cartridge/cassette selected with a voltage which represents the position of the store, and then moving the store in accordance with the difference in voltage; alternatively, a voltage difference is used to move an indicator to indicate which cartridge/cassette is being operated at any instant. In the arrangement shown, a cartridge in a store 201 (Fig. 2) is selected by holding a switch 3 (Fig. 1) closed until a self pulsing system 5, 6 has stepped an indicator 7 to the desired setting, whereupon a voltage representing the selection is obtained at a potential arm 11 ganged to indicator 7. A voltage representing the position of the store 201 is simultaneously obtained at an arm 102 ganged to the store, and when a detector 105 senses a difference in the two voltages (by detecting current in two resistors 16, 104 connected in series at 32, 132) a solenoid 128 causes a motor 131 to rotate the store. Rotation continues until a position is reached where the two voltages are the same, whereupon the chosen cartridge 202 is transferred to a playback system 204 for playback. The system is also effective to return the cartridge to the store at the end of of the tape, and to provide sequential playback of a series of cartridges, or repeated playback of a given one. A pro-selection of cartridges may be played back by using an R-C memory system (303, 304, as described with reference to Fig. 3, not shown). In the arrangement of Figs. 4, 5 (not shown), a voltage representing the position of the indicator (7) is compared with a voltage representing the position of the store (201), as above, and any disparity (as detected at 15) is caused to energize the pulsing system (5, 6) to move the indicator until it indicates the actual position of the store at that instant.

The piezo-electric filter described in Specification 925,547 is modified in that the resonant frequency of one of the resonators in the fundamental or a given overtone mode differs from that of the other (in the case of a pair) by an amount equal to from 5 to 110% of the frequency difference between resonance and antiresonance for the fundamental or the given overtone. This difference (for a given frequency) is a fixed amount dependent upon the material of the crystal. The selected percentage determines the band-pass of the filter. The filters described are in all respects physically identical to those described in the Specification 925,547, i.e. the invention is applicable to multisection filters in which the pairs to be considered are formed each from one of the series and one of the shunt resonators.
