Abstract: 1,017,055. Fishing reels. H. POLICANSKY. Oct. 4, 1962 [Feb. 15, 1962], No. 5930/62. Heading A1A. A fishing reel comprises a variable friction coupling between its winding handle 21 and the spool 8, the coupling comprising a friction member 37 engaging a friction surface 38 on the flange 8c of the spool 8 and the friction member 37 and the spool being rotatably mounted on a two-part spindle 9, 10 supported between frame side members 1, 2. The spindle part 10 is mounted in a slidable bearing 12 in the side member 2 and is screwed into a bore 11 in the spindle part 9 by means of a lever 51 to vary the pressure on the friction coupling. The lever 51 is keyed to the outer end of the spindle part 10 and is maintained in an adjusted position by a non-rotatable washer 54 urged by a spring 55 to abut a friction washer 53 located on the spindle 10 between the washer, 54 and the lever 51. The friction member 37 is secured to a pinion 32 driven by a gear wheel 31 secured to one end of a shaft 23 running in bearings 26 and having secured to the other end the winding handle 21. A compression spring 57 for urging the friction surface out of contact "with the coupling member 37 is disposed around the spindles 9, 10 between a flange 42 of the coupling member 37 and one of two ball bearings 16 on which the spool 8 is mounted. The pressure between coupling and spool can also be adjusted by rotating the part-spindle 9 whilst the partspindle 10 is prevented from rotating. For this purpose a knob 62 is connected to a pinion 60 engaging a gear wheel 58 keyed to the spindle 9. A compression spring 63 and two friction washers 64 located on the knob shaft 61 maintain the pinion 60 in the adjusted position. An annular member 35 rivetted to the member 37 has three equi-spaced radially projecting portions the arcuate spaces 44 therebetween being provided with ramps pressed out from the coupling member 37 to form three outwardly facing ratchet teeth. A pawl 45 slidably mounted in a cylindrical recess 47 in the slide plate 2 is urged by a compression spring 48 to engage the ratchet teeth to prevent rotation of the coupling 37 in an anti-clockwise direction as viewed in Fig. 3 (not shown). The spring 48 also holds a sealing disc 49 against the inside of a lubricating port 50. An audible clicking device, Fig. 3 (not shown) comprises a toothed ring 65 screwed on to the hub 8a of the spool 8 the teeth thereof being engaged by a finger 66 having a shaft 68 rotatably mounted in a radially extending slot in the side member 1 and provided with an operating knob 70 for disengaging the finger 66. The finger is urged into engagement with the teeth by a pair of semi-circular leaf springs 71 engaging recesses 72 in the finger. When disengaging the finger the knob 70 is pushed radially outwards and the springs 71 leave the recess 72 and grip the inwardly tapering side of the finger to maintain disengagement. The winding handle may comprise an arm hinged to the end of the shaft 23 by a lockable hinge disposed parallel to the arm.

Title: Boron compound
IPC: C06C5/06
Filed: 1962-02-16
Abstract: The double salt <PICT:0989295/C1/1> Cs2B12H12.CsNO3 is prepared by bringing together a source of B12H12= ions, a source of Cs+ ions and a source of NO3 - ions in a solvent inert to the reactants, and isolating the resultant product.  The source of B12H12= ions may be the dihydrogen, the diammonium, a di-(N-substituted ammonium) or a di-(alkali metal) salt and the source of NO3 - ions may be nitric acid or an alkali metal nitrate.  In the reaction medium, the preferred molar ratio of NO3: B12H12 is at least 3.  The cesium salts of B12H12= and NO3 - may be used in the reaction. The preferred solvent, or reaction medium, is water. The double salt product, which is usually separated by precipitation or crystallization and filtration, is used as an ignition composition in electric initiators and squibs.  The initiators are constructed (see Figure) of a shell 11 having a closed end into which is loaded a base charge 12 of conventional explosive, e.g. cyclonite, PETN, picric acid, T.N.T. ethylene dinitramine, tetryl or mixture thereof.  Above 12 there is a primer charge 13 which is a usual primary explosive, e.g. lead azide, or mercury fulminate. Above 13 is the loose ignition charge 14 of the double salt, in which is placed a bridge wire 15 connecting lead wires 16 which are held in place by rubber plug 17 which also seals shell 11. Other conventional sealing means may be employed.  The squib is of similar construction, but the charge consists wholly of the double salt.  Specification 989,293 is referred to.

Abstract: 1493516 Control of AC motors; switching systems for consuming devices; electrical connectors J BAKER 14 Feb 1975 [14 Feb 1974 18 Feb 1974 22 March 1974 27 March 1974 14 May 1974 31 May 1974 7 Nov 1974] 6419/75 Headings H2J H2H and H2E The current to an electrically powered device, disposed in or adjacent a room for performing one or more functions arising from the use of heated water in the room, is controlled in response to variations in the temperature of a pipe supplying heated water to a water outlet in the room. The device may be a fan, an electrically heated floor, carpet or towel rail or a room heater. The current may be controlled by one or more thermostats. Fig. 1 shows the application of the invention to control an exhaust fan 5, operable to remove steam from a bathroom when a hot water tap therein is turned on. A thermostat 4 senses the temperature of the hot water supply pipe 8 and switches the motor driving the fan respectively on or off, when the pipe temperature exceeds an upper or falls below a lower value. Members 4, 5 may be a combined fan and thermostatic control unit or, as in Fig. 1, the thermostat 4 may be connected to an adaptor 2 plugged into a mains supply socket 7 and in turn receiving the plug 6 of the fan. As shown in Fig. 2B the adaptor 2 has a gap 18 between its live plug and live socket members, which are connected to respective leads 21, 22 from the thermostat 4 to couple it in series with the live connection to the fan motor. The latter may be in parallel with additional electrical devices (20) such as a room heater and a towel rail, all controlled by the thermostat 4, Fig. 3 (not shown) or, dispensing with the parallel connection, each controlled by a respective thermostat responsive to the pipe temperature. The circuit of Fig. 4 provides a modification for ambient temperature, which is sensed by a second thermostat 10 (located for example in the roof) set to open at a temperature below the range of the thermostat 11 normally controlling the fan 5, whereby the latter is then controlled by a third thermostat 12 responsive to the temperature of the pipe and having an operating range higher than that of the thermostat 11. The room heater 20 is controlled by a further thermostat 13 responsive to ambient temperature and having the lowest operating range. In the single thermostat arrangement of Fig. 1, a time delay switch may be added to the circuit to change it between manual and thermostat control of the fan.
Patent GB-627094-A (GB)
Title: Improvements in the manufacture of hats and other shaped articles of textile material
IPC: A42C1/04
Filed: 1947-03-07
Abstract: In the method of making hats and other shaped articles by sewing a ribbon, braid or other textile fabric to the approximate shape desired and setting the article in the final shape under heat and pressure, the braid or fabric is made of or contains fibres of a thermoplastic derivative of cellulose and is sewn in a stiffened condition produced by treatment of the braid by a high-boiling point plasticiser for the cellulose derivative followed by extraction of the plasticiser.  In an example, a braid containing cellulose acetate fibres is dipped in a solution of 30 per cent dimethoxyethyl phthalate in isopropyl alcohol and passed between rollers, followed by drying in a hot air oven at 105 DEG  C., at which temperature the braid becomes soft.  The dimethoxy ethyl phthalate is extracted by dipping in ethyl ether and the braid on drying becomes slightly stiff.  In a modification of the method, the plasticiser is present in the cellulose derivative fibre before formation of the fabric. Other thermoplastic derivatives of cellulose which may be used are the cellulose esters cellulose propionate and cellulose butyrate or the cellulose ethers methyl cellulose, ethyl cellulose and benzyl cellulose.  For cellulose acetate, the water-insoluble plasticisers dimethoxyethyl phthalate, dibutyl tartrate, triethyl citrate and p-toluene sulphonamide and for ethyl cellulose, tricresyl phosphate and triphenyl phosphate, may be used and extracted by hydrophobe volatile liquids.  Other plasticisers extractable from the material by water include liquids which are solvents for cellulose acetate at atmospheric temperatures, e.g. diacetin, as well as liquids which are solvents for cellulose acetate only when hot, e.g. glycol and glycerol.
