Abstract: 1,115,659. Floor polishing machines. ELECTROLUX Ltd. 22 Nov., 1965, No. 49495/65. Heading A4F [Also in Division H1] A floor polisher comprises a belt pulley 11 (Fig. 1) supported by ball bearings 13 on a shaft 14, dependent from frame 10, and a screwed bearing cover 15 supports a permanent magnet 16 of hemispherical shape having a diametrical recess 17 which may contain a non magnetic e.g. plastic sleeve 26. The magnet co-operates with a hemispherically cupped armature 18 of soft sheet iron extending through the centre of a polishing brush 12 into a downwardly extending cone 20 serving as a finger grip and as a guide receiving a coned ferrule of an overlying polishing or grinding disc (not shown) which may be centrally cupped to engage the magnet surface. A protruding pin or rivet is snapped into the non magnetic sleeve. Drive is transmitted from the pulley to the brush by gravity or spring biased axially slidable pins 29 having heads 31 engaging stops 30 of the brush. Plural magnets may be used; diametrically opposed, peripherally spaced, or disposed centrally. The magnet member may be concave, and the magnet and armature may be transposed.

Abstract: 1,129,159. Viewfinders. RUMANIA STATE BOARD FOR CULTURE & ART. Nov. 4, 1966, No.49561/66. Heading G2E. In a motion picture camera, the image 1 formed on the film 3 by the objective lens 2 is viewed by the eye of an observer at 7. In Fig. 1 the direction of viewing is at 90 degrees to the optical axis, the light rays from the film passing through a prism and lens system 4, 5, 6. In Figs. 2 and 3 (not shown) the observer is behind the film, and views the image 1 through a prism and lens system which permits viewing in a direction parallel to the optical axis. Thus the distortion caused by the observer viewing the image 1 at an acute angle is removed by the reflecting system. This viewfinder arrangement may be used additionally to the existing camera viewfinder, for checking purposes.

Patent GB-506911-A (GB)
Abstract: 506,911. Cathode-ray tubes. RING, F. Oct. 25, 1937, No. 29085. Convention date, Oct. 26, 1936. [Class 39 (i)] To obtain a persistent image on the fluorescent screen' 2 it is scanned by a modulated beam from a gun 10 to produce a charge distribution on the screen, which is then diffusely irradiated by electrons from a flooding cathode 6, these electrons being accelerated by an electrode 4 in front of the screen. The-potentials of the electrodes and the screen material are chosen so that-due to secondary emission resulting from the impact of the scanning beam-the charges on the screen are above or below a critical datum potential; the flooding electrons from the cathode 6 will take the areas above this critical potential to an upper datum level determined by the potential of the electrode 4 while those areas below the critical potential will sink to zero potential. The electrode 4 collects secondaries emitted from the screen. The screen is returned to a datum potential which may be zero or the upper datum set by the electrode 4 ; the return to a datum may be effected by a beam preceding the scanning beam, by a light ray or by lowering temporarily the potential of the electrode 4. Reference has been directed by the Comptroller to Specification 481,094.

Title: Carburation devices for internal bombustion engines
IPC: F02M1/04
Filed: 1972-11-08
Abstract: 1412615 Spray carburetters SOC INDUSTRIELLE DE BREVETS ET D'ETUDES 8 Nov 1972 [17 Dec 1971] 51452/72 Heading F1B A carburation device for an I.C. engine comprises an intake pipe 1 in which upstream of a principal throttle member 2 actuated by the driver is an auxiliary throttle member 3 which opens automatically as the flow rate of air passing through the pipe 1 increases and which controls a metering member 4 regulating fuel flow from a  source 14 substantially at atmospheric pressure to produce a substantially constant richness mixture during normal operation, there being a starting system including a first fuel circuit which opens into the intake pipe at 66 and in which is a valve through which fuel flow is allowed to increase by a temperature sensitive member 19 as temperature drops, the valve being partially closed by a pneumatic member (diaphragm 35) when the pressure in the pipe 1 downstream of throttle member 2 drops below a certain value. A second full circuit, part of which is in parallel with part of the first, is controlled by the pneumatic member but not by the temperature sensitive member, so that the second fuel circuit is opened when the engine is stopped or driven by the starter and closed when the engine is running, this second circuit being in operation only if the first circuit is open. The first circuit comprises orifice 59 in chamber 14, passage 81, orifice 60, chamber 61, orifices 51 and the inner portion 62 of a tube 49, orifices 52, chamber 63, channels 64 and 65, an orifice 66 and chamber 13. The second fuel circuit connects a counter bore 58 to channel 65 via channel 71 and orifices 70 and 74 and contains a valve formed by a ball 67 and a sealing washer 68 which serves as a seat. When the engine is cold and stationary, the bi-metallic spiral 19 acts through a lever 22, one end 47 of which holds tube 49 downwardly so that the first fuel circuit is open. When the starter turns the engine, the pressure downstream of throttle member 2 is not low enough to move diaphragm 35, to which is attached a rod 40, upwards against a spring 46 so the rod 40 holds a push-rod 72 down and keeps ball 67 from its seat 68. Thus the second circuit and the first are still open. When the engine starts and the load is low, rod 40 is raised by diaphragm 35 so that pushrod 72 can rise allowing ball 67 to close on to seat 68 closing the second fuel circuit. If the throttle is opened wide while the engine is still cold, rod 40 is caused to descend again by the diaphragm 35 and the spiral 19 acting through end 42 of lever 22 but ball 67 remains on seat 68 so that the second fuel circuit is closed. When the engine is hot and at rest, Fig. 4 (not shown), the spiral 19 causes lever 22 to rotate clockwise allowing tube 49 to rise, so closing the first circuit and preventing the second from operating, irrespective of the position of the ball 67.

The heat-sensitive layer may also contain a metal salt of a fatty acid having between 10 and 22 carbon atoms which acts as a heat-fusible material and does not enter into the colour forming reaction. The stencil may be imagewise exposed to heat which causes fusion and perforation of the resin layer and formation of a coloured image in the perforated areas. The formation of the coloured image allows the correct exposure to be more easily determined. Specified compounds which change colour are cobalt and nickel complexes of hexamethylene tetramine. Specified compositions which change colour are: (1) a benzoin a phenol or a polyhydric alcohol, sulphur and a metal salt or a Co or Ni complex as above, (ii) heavy metal organic salts with sulphides or sulphur containing compounds (iii) ferric soaps with phenolo or thiosemicarbazides or zincdialkyl dithiocarbamate (iv) lead salts with thioureas (v) silver salts with reducing agents or polyhydric alcohols and (vi) resorcinol and nitroso compounds.
