Title: Selective calling receivers
IPC: H04W84/02
Filed: 1976-09-09
Abstract: 1524128 Selective calling receiver DAINI SEIKOSHA KK 9 Sept 1976 [10 Sept 1975] 37400/76 Heading G4H A selective calling receiver comprises a sound circuit 1 which generates an audible calling sound in response to a calling message, a register 19 in which received messages are stored, a circuit D for displaying the stored message, and a manually operated control circuit 12 which turns off the sound circuit and causes circuit D to display the message stored in register 19. Receipt of a message causes a bistable 2 to be set and an astable multivibrator 5 in sound circuit 1 to be actuated. The resulting sound is maintained until bistable 2 is reset by operation of a switch 13 in circuit 12, operation of this switch also serving to enable gates A1, ..., An, so that timing signals P 1 , ..., P n  can control the operation of circuit D and the transfer of the message thereto via gates TG11- TG14 &c. and decoder 20. The display may be a 7-segment L.E.D. display.

Filed: 1959-02-19
Abstract: 862,076. Drying granular materials. MARK, A. Feb. 19, 1959 [Feb. 25, 1958], No. 5731/59. Class 34(2) Granular material is dried whilst entrained in a stream of hot air flowing through a spiral passage a to n, Fig. 2, formed by a coiled metallic band 2 disposed between two vertical parallel walls 1, 3, of which the wall 3 is removable for passage cleaning purposes whilst the wall 1 accommodates a dried material outlet o. The material is passed into the hot air stream issuing from a hot air generator 12 and a blower 9 through an air lock 15 and is carried along the passage to the outlet o from whence it is drawn by an exhaust blower 7, Fig. 1, through a cyclone separator 5. The dried material collected in this separator is discharged through an air lock 8. As the band 2 is irregularly coiled, broken at 2a, 2b, and has the cut end 2c projecting below the outlet o in order to form a recirculating conduit p, the air entrained heavier, and, therefore, presumably wetter, particles are caused to return to the lower zone d<SP>1</SP> of the first passage turn as they are passing through the lower zone h of the second turn and to pass to the lower zone l<SP>1</SP> of the third turn when they fail to negotiate the right angled deviation into the outlet o. Through the irregular band coiling the air stream velocity varies in the passage sections a to n. The exhaust blower 7 may be omitted.

Title: Method of accelerating and/or promoting chemical reactions and emulsification
Inventor: FUKUSHIMA FUMIAKI
IPC: B01J47/06
Filed: 1962-10-11
Abstract: In Example 3, grape sugar is obtained from sweet potato starch by adding an aqueous dispersions of the starch to a solution of Al2(SO4)3 containing H2SO4 with stirring at 59 r.p.m., the stirred mixture being subjected to a magnetic flux produced by a permanent magnet and to oscillations produced by a crystal oscillator operated at 2.5 kw. and 117 kc./s.  The resulting solution is worked up to give crystalline sugar.ALSO:Reactions (including ion exchange) and emulsification may be promoted or accelerated by subjecting the materials to a magnetic field having lines of force extending in one direction therethrough whilst applying a mechanical force to said materials in the field so as to act in a direction perpendicular to said lines of force.  The magnetic field may be supplied by a permanent magnet or electromagnet or by one or more solenoids provided on the outer walls of the container and supplied with D.C. or A.C. e.g. of 10-300 Kcs.  The mechanical force may be supplied by stirring and/or ultrasonic vibrations generated by an A.C. of 10-300 Kcs.  The reactions may be between solids, liquids, gases, solids and liquids, liquids and gases or gases and solids and may be effected in a non-conductive vessel e.g. of cement, glass, rubber, ceramic, synthetic resin or wood.  A magnetically permeable layer e.g. of low carbon or silicon steel or permalloy insulated with mica, asbestos or synthetic resin may be interposed between the solenoid coils (where used) and the vessel wall; an electrically conductive body e.g. of metal, metal oxide or graphite, may be provided at the centre of the vessel, insulated from the exterior, whereby the magnetic field is concentrated within the vessel.  Where undesired oxidation or hydrolysis occurs, an easily oxidisable substance, e.g. C, Pb or Ni, may be present as part of the stirrer or the electrode or pole generating the ultrasonic vibration or as an electrically positive diaphragm surrounding the electrode or pole and covered with Fe3O4, Cr2O3 or TiO2, to inhibit side reactions.  In Example 1, a stable cationic asphalt emulsion is obtained by adding the asphalt to a mixture of water, formamide, stearic amine, urea, calcium chloride and acetic anhydride whilst stirring the aqueous mixture at 1000 r.p.m. in a magnetic field produced by an 80-100 A, 10 KW A.C. of 182 Kcs flowing in a cooled coil.ALSO:In Example 2, barley straw is cut into 1-1 1/2 cm. lengths and added to a solution prepared by stirring Ca(OH)2, Na2CO3, Na2S and S into water.  The mixture is stirred at 50 r.p.m. in an alternating magnetic field produced by a pair of solenoids encompassing the reaction vessel, for 45 mins.  The resultant fibres were beaten to provide a pale yellow unbleached pulp.

Abstract: 345,263. Printing-surfaces. WADE, H., 111, Hatton Garden, London.-(American Multigraph Co. ; Kelly Avenue, Cleveland, Ohio, U.S.A.) Dec. 17, 1929, No. 38638. [Class 100 (ii).] A printing-plate, on which an image has been prepared, is treated with a substance which will render the plate initially ink-repellent on the plain portions but will not injure the image, and printing is effected with an ink which will adhere on to the image and contains a substance which will continue the surface-treatment of the plate and maintain the plain portions in ink-repellent condition. An aluminium plate for planographic printing has the image produced thereon in fatty or greasy ink by means of a lithographic pencil or other method, and the surface is then rubbed with a solution of a nitrate or sulphate, preferably ammonium nitrate or sulphate, or aluminium, nickel, iron, or copper nitrate. After drying, direct or offset printing is effected with ordinary lithographic ink to which a substance similar to that used for treating the plate, and preferably ammonium nitrate or aluminium nitrate or sulphate, has been added, damping being unnecessary. In the preparation of a photomechanical plate, the nitrate or sulphate solution is added to the light-sensitive layer, and the plate, after exposure, is developed with a developer which will not dissolve the nitrate or sulphate. For intaglio printing, the aluminium or aluminiumcovered plate is etched in the usual way, the etched parts are inked with a fatty ink containing the nitrate or sulphate solution, and the remaining parts are rendered ink-repellent. If a zinc plate is to be used, a phosphate, preferably ammonium monohydrogen phosphate, is added to the preparing solution to prevent oxidation or corrosion of the plate.

A swing- ing frame comprising sick members 9, 10 rigidly connected by cross-members 11 is raised and lowered within the opening about a shaft 13, acting as a pivotal point to provide an incline for the wheels of the semi-trailer, by a shaft 23, Fig. 4, journalled in transverse bearings on the truck frame and carrying lever arms 23a. Rollers 24 journalled to the arms 23a co-operate with arcuate cam surfaces formed on the undersides of the ends of the members 9, 10 to control the movement of the swinging frame. The shaft 23 is manually operable through gearing 22 by a crank 20. Transverse cross-members 15a, 15b, which support the swinging frame throughout its movement are secured at 28 to arms 25 which form the lower portion of linkages in the form of pairs of compasses, the upper arms 26 of which are pivoted thereto at 27 and at 29 to a side-member of the swinging frame.

Separate rail sections 34, 36, 37 are secured, respectively, to base-plates 35 on the truck frame, to side-members 9, 10 on the swinging frame and to base-plates 38 on the truck frame, The rails guide spacer drums 33 fitted between spaced pairs of twin wheels on a common axle of the semi-trailer over the full extent of the truck, the rails being held between the tyres of adjacent wheels. A transverse abutting surface 39 of the truck frame formed with elongated apertures to allow the lever arms 23a to project forms a stop against which the tyres bear when the swinging frame is in the lowered position. The semi-trailer is secured on the truck by a king-pin depending from a bearing surface of the trailer which projects into a longitudinal slot 44 formed in a co-operating bearing surface 41 on the truck platform, where it is resiliently blocked against longitudinal displacement.
