Title: Improvements relating to apparatus for producing signals indicative of relative position
Inventor: LONG ARTHUR HENRY
IPC: G01B7/00
Filed: 1965-08-20
Abstract: 1,082,096. Measuring displacement electrically. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug.4, 1966 [Aug.20, 1965], No.35813/65. Addition to 953, 449. Heading G1N. The displacement measuring device disclosed in Specification 990, 928 in which four intercalated sets of conductive strips S1-S4 &c., move relative to a member 1 having a conductive toothed profile, is modified so that these sets are sub-divided into two pairs of interlaced strips S1, S3 &c., and S2, S4 &c., placed side by side in non-intermeshing relationship. The interlaced strips may project from a pair of parallel bus-bars, Fig. 2 (not shown) and embedded in moulded resin. In a modification, Fig.3 (not shown), one pair of strips may be duplicated and mounted one on either side of the other pair, thus reducing errors due to tilting of the toothed member. The strips are skewed to reduce the harmonic content of the output signal and the strip assembly may be produced by printing. The arrangement may be arranged in annular form to measure angular displacements.

Inventor: NOYES BERNARD HARRY
IPC: B60Q1/14
Filed: 1959-10-23
Abstract: 888,157. Photo-electric control of vehicle headlamps. KISMET Ltd. Oct. 24, 1960 [Oct. 23, 1959], No. 35991/59. Class 40(3). An automatic headlamp dipping system in which a photoresistance operates a relay, includes means for selecting high or low beams at will. With the switch 13 in position 15, illumination of the photoresistance 2 causes a transistor TR2 to pass current, energising the relay 9 to switch to low beam. Resistor R1 and capacitor Cl reduce the delay in switching back to high beam on removal. of illumination. At any time the arm 17 may be moved to either of positions 14 or 16 which provide low and high beams respectively. The Provisional Specification describes a circuit using only one transistor and with no R1, C1 network.

Abstract: 399,349. Coin-actuated game apparatus ; table games. BRYAN, W. E., Bryan's Automatic Works, London Road, Kegworth, Derbyshire. Dec. 20, 1932, No. 36029. [Class 27.] Coin action, weight.-Coin-actuated amusement apparatus comprises a table pivoted for movement about a horizontal axis but normally held horizontal, a shoot or the like for projecting coins on the table, a target associated with the table, and means for tipping the table on the engagement of a winning coin with the target to deliver to the player the coins accumulated on the table. As shown, a plurality of tables 7 are disposed beneath a glass top 4. and each is provided with a hole 7A communicating by a shoot 15 with a pivoted flap 16 mounted on a spindle 14 connected with the table by linkwork 11, 10, 9 so arranged that the table cannot be tipped by the weight of coins thereon. A coin entering one of the holes 7A, after projection over the table by an adjustable shoot 17 hits the flap 16 and thus actuates the linkwork to tip the table and deliver any coins thereon to the player by way of an inclined surface 20 leading to a side opening, the actuating coin itself being retained in the machine. Each flap 16 is adapted, when actuated, to lock the flap of the preceding table against actuation. The tables are reset by a handle 23 connected with a slide 21, pins 24 on which engage the arms 9 associated with the table. According to the Provisional Specification, the coins may be projected by hand or by a spring gun; the tables may be restored by a spring or by gravity ; coins not reaching, or passing beyond, the table may be automatically returned and the holes 7A and flaps 16 may be replaced by upright pins adapted to be hit by the coins. Testing coins.-The flaps 16 have holes 16B through which small coins pass without actuating the flap.

Title: Improvements in or relating to the manufacture of compounds of the benzanthrone series
IPC: C09B3/02
Filed: 1933-12-23
Abstract: The proportion of by-products formed in the oxidation of benzanthrone for the ultimate production of Bz-2 : Bz-2<1>-dihydroxydibenzanthrone and of vat dyestuffs obtained therefrom, is reduced by carrying out the oxidation with managanese dioxide and somewhat diluted, e.g. 80 per cent sulphuric acid, and/or by a restriction of the time of reaction so that only a portion, e.g. 60 to 70 per cent of the benzanthrone is oxidized to Bz-1 : Bz-1<1>-dibenzanthronyl.  The reaction product is subjected to reduction with bisulphite and extraction with alkali to remove by-products, and may then be either further extracted with organic solvents or with 75--80 per cent sulphuric acid to remove unchanged benzanthrone, or the mixture of Bz-1 : Bz-1<1>-dibenzanthronyl and unchanged benzanthrone may be fused with caustic alkali and subsequently oxidized with sulphuric acid and manganese dioxide for the production of Bz-2 : Bz-2<1>-dihydroxydibenzanthrone.  In examples: (1) purified benzanthrone is dissolved in 80 per cent sulphuric acid and cooled to 2 DEG  C., pyrolusite added during 7 to 8 hours, and the mixture stirred for 15 to 20 hours, the temperature being maintained throughout at 2 to 4 DEG  C.  A small quantity of water is then added and the product washed on a porous plate with 75 to 80 per cent sulphuric acid, whereby unchanged benzanthrone and any oxybenzanthrone are removed.  The product is finally boiled with bisulphite to remove residual manganese.  (2) The reaction mixture of example 1 is diluted with large excess of water, the product boiled with bisulphite, filtered, washed with caustic soda, and finally washed with warm toluene to remove unchanged benzanthrone. (3) Stronger acid (94 per cent) is used for the oxidation, but the reaction time is limited to 4 hours.  The reaction product is treated with bisulphite and alkali, but the unchanged benzanthrone is not removed, approximately 35 per cent being present together with 65 per cent Bz-1 : Bz-1<1>-dibenzanthronyl.  (4) The process of example 2 if stopped short of the final toluene extraction yields a yellowish brown powder containing approximately 70 per cent of substantially pure Bz-1 : Bz-1<1>-dibenzanthronyl and 30 per cent unchanged benzanthrone.  (5), (6) The products of examples 3 or 4 are fused at 130 DEG  C. with a melt of methanol, fused potassium acetate, and caustic potash, drowned in cold water, and aerated until the dyestuff is completely precipitated.  The product is oxidized with manganese dioxide and 93 per cent sulphuric acid at 20--25 DEG  C., and after filtering and treatment with bisulphite consists of Bz-2 : Bz-2<1>-dihydroxydibenzanthrone of great technical purity.  (7) Pure Bz-1 : Bz-1<1>-dibenzanthronyl obtained according to example 1 is oxidized as in example 6. Specifications 251,313, 275,927, 278,112, [all in Class 2 (iii)], and 418,202 are referred to.

A cathode for a thermionic converter comprises a ceramic body having its surface fitted to anchor a metallic coating to it; the pits being so small that the elastic energy stored in the roots of the coating is insufficient to provide the surface energy required for their detachment despite any difference in the thermal coefficient of expansion between the ceramic and coating. Pit dimensions: Diameter 5 . . . 10 microns, depth 5 . . . 10 microns, spacing 15 . . . 50 microns. Producing pitted ceramic surface: (i) Ultrasonic drilling by tungsten wire brush, or (ii) wet moulding on a whiskered metal surface; firing to a moderate temperature; etching away metal and completing firing, or (iii) wet moulding on a surface of ordinary or nylon velvet, which is burnt out during firing. Metal coating: (i) Tungsten is sprayed on with a " plasma " gun, and the process completed by spraying with a mixture including an electron-emissive-material; (ii) tungsten and copper, or tungsten and molybdenum may be sprayed on and one of the metals chemically dissolved to leave a porous surface to receive the electron-emissive-material; (iii) a coating of dense metallic tungsten (a few thousandths of an inch thick) is produced by disassociation of tungsten hexacarbonyl on the hot ceramic surface. This coating is reduced in hydrogen and impregnated with barium - strontium aluminate. Emissive surface: May be alkaline earth or rare earth oxides, or rare earth oxides, or rare earth hexaborides, or aluminates of alkaline and rare earths. The surface is preferably deeply pitted to increase its total area; this may be achieved by adding a filler powder in the last stage of spraying, and removing the powder by chemical means. Cathode connections: Figs. 3, 4 (not shown) illustrate thermionic generators in which the cathode lead is (i) an elastic metal tube within a tubular ceramic cathode carrier and is brazed thereto, or (ii) the ceramic tube beyond the pitted part is coated with graphite, and the whole inner surface of the ceramic is sprayed with metal.
