Title: Crank driven press and fluid control therefor
IPC: B30B15/14
Filed: 1968-06-07
Abstract: 1,236,443. Mechanical presses. E. W. BLISS CO. 7 June, 1968 [6 July, 1967], No. 27249/68. Heading B5F. [Also in Division F2] In a press (10), Fig. 1 (not shown), driven by a crank-shaft 12, the alternating disengagement and engagement of a friction brake 20, Fig. 2, coupled to the shaft is controlled by a valve 38 operable in response to crank-shaft rotation to connect a brake-operating cylinder 24 to a pressure source P in one position or to cause its exhaust in a second position, which latter is controlled by a second valve 30, connected between the valve 38 and cylinder 24, which is responsive to the second position of the valve 38 to cause controlled exhaust of the cylinder through a separate exhaust means. As described, the friction brake 20, engageable against plate 28 keyed to the crank-shaft, is combined with a clutch plate 22 carried on flywheel 16, to be operated therewith to operatively connect the shaft to the flywheel when the brake is disengaged and cylinder pressurized and vice versa when the cylinder is exhausted. The control valve 38 is operated by solenoids 39a, 39b whose energization is controlled by e.g. limit switches set to be operated at a predetermined point in the crank-shaft rotation, to alternatively connect the air-pressure source P to the cylinder 24, when energized, and to connect the input 34 to the valve 40 to exhaust line 62 when de-energized. This latter causes valve 40 to disconnect the cylinder 24 from the valve 38 and to connect in to controlled exhaust line 64 including a surge tank 65 for rapid partial brake engagement and a restriction 67 for a more slow complete engagement. The valve comprises input chamber 45, Fig. 3, connected to valve 38, output chamber 49 connected to the cylinder 24 and exhaust chamber 49<SP>1</SP> connected to exhaust line 64. The three chambers are connected by two passageways 46, 47 each provided with a sleeve 51, slidable to close the connection to the exhaust chamber 49 when it is seated against seat 54 and a poppet 52 movable relative to the sleeve and spring biased to close the lower end of the sleeve and thereby disconnect chambers 45, 49. When the pressure of fluid in chamber 45 is greater than that in chamber 49 the poppet opens until equilibrium is established while the sleeve is located to close the connection to chamber 49<SP>1</SP>, but if the pressure in chamber 45 is reduced the valve as a whole moves to open the connection between chambers 49, 491, the poppet remaining seated isolating chamber 49 from chamber 45.

Title: Improvements relating to colour television apparatus
IPC: H04N9/44
Filed: 1945-10-19
Abstract: 622,202. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 19, 1945, No. 27451. Convention date, Oct. 19, 1944. [Class 40 (iii)] In colour television apparatus comprising a rotatable colour filter wheel having a conducting portion serving as the moving part of an electromagnetic brake, the speed of the wheel is controlled in accordance with synchronizing signals by applying to an electromagnet acting on the conducting portion a current dependent on the phase difference between the synchronizing signals and a signal generated locally at a frequency dependent on the speed of the wheel. In the arrangement shown in Fig. 1, the locally- .generated signal, which comprises a sinusoidal voltage (Fig. 3) generated by the toothed rotor 38 of an inductor alternator 39 is applied via a phase-adjusting network 68 to the grid of a valve 51 to another grid of which are applied synchronizing pulses (Fig. 2) from the vertical deflection apparatus 19, the adjustment of the network 68 being such that a minimum current flows through winding 73 of the electromagnetic brake when the frequency of the sinusoidal voltage (i.e. the speed of the colour filter-wheel 26) is equal to the frequency of the synchronizing pulses. For other speeds the current through 43 increases, thus exercising a retarding effect on the metallic rim 42 of the colour wheel. In practice the speed of the driving motor is adjusted to be slightly greater than the desired speed. Specification 359,947 is referred to.

A gas having a high content of H 2  and CO is made by catalytically hydrogenating a gas derived from the carbonization of coal, and catalytically cracking the hydrogenated gas in the presence of steam, and optionally of air. Hydrogenation is carried out over a cobaltmolybdenum catalyst (converting organic sulphur compounds to H 2 S and olefines to saturated hydrocarbons) at a pressure in the range 1.5 to 30 atmos. absolute and a temperature in the range 250‹ to 700‹ C. Cracking is carried out over a nickel catalyst at a pressure in the above range and at a temperature in the range 600‹ to 1200‹ C. H 2 S is either removed from the gas between the hydrogenation and cracking stages, or, with naphthalene, prior to hydrogenation. The initial gas is cooled for the removal of liquids prior to hydrogenating, and naphthalene may be removed by washing the gas with these liquids, before or after compressing the gas to hydrogenating pressure. Alternatively, the temperature may be kept above the naphthalene dewpoint during hydrogenation and H 2 S removal. Two specific examples are described.
