Title: Improvements relating to the manufacture of gasoline-like hydrocarbons by the polymerisation of hydrocarbon gases
IPC: C07C9/14
Filed: 1937-01-19
Abstract: <PICT:0489105/IV/1> Hydrocarbons suitable for use as motor fuel are obtained by subjecting a stream of normally-gaseous hydrocarbons to elevated temperature and pressure sufficient to convert them to normally-liquid products which are immediately cooled by contact with an absorbent oil containing absorbed gaseous hydrocarbons, separating the gasoline products from the gases and returning the gases to the conversion stage.  The crude gases are preferably washed with an oil to absorb the fixed gases contained therein and this oil is used to absorb the hot conversion products.  Mixed gases containing hydrogen, methane and paraffins and olefines having two to four carbon atoms per molecule, e.g. gases from a cracking plant, are delivered by a compressor 10 through a line 11 into a high-pressure absorber 12 provided with plates, trays, &c. 13 where the gases are treated with a countercurrent flow of oil admitted through a pipe 14.  The residual gases, e.g. hydrogen and methane, escape through a line 15 while the absorbent oil with dissolved gases is passed through heat exchanger 22, and either through coil 87 and line 88 or through line 20, into a fractionating tower 25 into which the conversion products are introduced through a line 26 and from which reflux is re-cycled through lines 27, 29, 31 to the tower 12.  Products in the gaseous state escape through line 35, cooler 36, separator 37, and stripper 47, where gases are separated and re-cycled through line 40 to tower 12, to a stabilizer 54 from the bottom of which stabilized gasoline is withdrawn.  The gases which escape from the stabilizer are passed through a cooler 62 and purifier 68 and after compression by a pump 73 are passed to the conversion coil 75 and soaker 78 the products being cooled in the line 26 by admixture with oil from the tower 12 supplied through line 81. Temperatures of 750-1250 DEG  F, or 400-600 DEG  F., in presence of a catalyst, are maintained in the coil 75 while the pressure in the tower 25 is in excess of 200 lb. per sq. inch.

Title: Improvements in or relating to hollow spindle collet chucks
IPC: B23B31/20
Filed: 1952-01-24
Abstract: 697,440. Chucks. THOMPSON PRODUCTS, Inc. Jan. 24, 1952 [Jan. 30, 1951], No. 1965/62. Class 83 (iii). A hollow spindle chuck comprises a collet 24, fitted in one end of the spindle 11 and engaged by a closing sleeve 13 shifted by rockable fingers 16 engaging a cam sleeve 19, and a work locator 21 adjustably fitted in the other end of the spindle to control the projection of the work, such as a poppet valve 23, beyond the spindle. The work-locator is screwed in a nut 20 and locked in adjusted position by an inclined set-screw 22. To open the chuck, a ring 26 is moved up so that it engages prongs 19e extending through the nut 20 and moves the cam sleeve 19 to the right until the ends 16b of the fingers 16 lie on the larger-diameter portion 19d of the sleeve, the fingers being swung outwards by centrifugal force. The closing sleeve 13 is thus allowed to move back under the expansion of the collet, which is assisted by centrifugal force. To close the chuck, a ring 15 is moved up from the other side and moves into slots in the chuck so that, through segments 14, the cam sleeve is moved to the left, causing the fingers to pivot round their points of contact 17 with a pressure ring P.R. and move the sleeve 13 to close the jaws. An adjusting nut 12 is set and locked by serrations on its periphery and by a plate D so that the jaws grip the work with the correct pressure just before the ends 16b of the fingers reach the smaller-diameter portion 19b of the cam sleeve and then the fingers flex until they engage the portion 19b and are therefore locked there. Rotation of the adjusting nut 12 also rotates the sleeve 13, the segments 14 and the fingers 16 to new positions, so that wear of the cam sleeve 19 and the pressure ring P.R. is distributed.

Title: Manufacture of microwave devices
IPC: H01P1/19
Filed: 1975-10-17
Abstract: 1464511 Ferrite phase shifters GENERAL ELECTRIC CO Ltd 17 Oct 1975 [17 Jan 1975] 2121/75 Heading H1W [Also in Division B3] A microwave device comprises one or more conductors of Ru, Rh, Pd, Os, Ir, or Pt, or alloys or two or more of these metals on, or in grooves in, a first body of ferrite material onto which ferrite powder is arc plasma sprayed. The first body may be a refractory ceramic insulating substrate, e.g. alumina, magnesium titanate, or a composition similar to forsterite, on to which ferrite has been sprayed, but in an example is a sintered block or plate of magnesium manganese ferrite 4 having grooves into which platinum loops 8 are rolled. The assembly is then mounted in a gas-fired furnace, its edges masked, it is heated to 1000‹ C., and then sprayed in raster fashion by a plasma gun, to give the required thickness of deposit 9. Desired microwave circuit elements are formed on the free surface of block 4, e.g. three strips 10, each formed by depositing a chromium film, then a gold film, then a further layer of gold. In an alternative example, the conductors are formed from applying a suspension of platinum powder and glass powder. The ends of the conductors, exposed after spraying the ferrite powder, are painted over with glass bonded silver paste and fired, tin-plated copper wires being soldered to the terminals so formed. A latchable phase shifter incorporating the component made in accordance with either example is made by joining two leads diagonally of the component by wire 11, Fig. 6, leaving the other two for connection to an energizing circuit. The component is mounted on ledges 14 in an aluminium box 12 with lid 13, and connection is made to coaxial connectors 16 so that one contact member 20 at each end hinges the two outer strips 10, while another (not shown) makes contact with the central strip 10.

Title: Improvements in or relating to frequency multiplying apparatus
IPC: H03B19/10
Filed: 1936-01-24
Abstract: 469,416. Generating highfrequency oscillations. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and KEALL, O. E. Jan. 24, 1936, No. 2350. [Class 40 (v)] A frequency-multiplying arrangement includes means for filtering out the carrier component in a carrier frequency modulated by an initial frequency, means for rectifying the envelope of the resultant remaining side bands, and means for selecting a desired harmonic of the initial frequency from the rectified resultant. In one arrangement, Fig. 1, the modulated carrier frequency received on an aerial 1 is applied via a circuit 2 tuned to the carrier frequency and an amplifying valve 5 to a circuit 6, also tuned to the carrier frequency. The circuit 6 is shunted by a piezo-electric crystal 7 series resonant to the carrier frequency, and by a diode 8 in series with a resistance 9. The latter is shunted by a parallel tuned circuit 10 resonant to the desired harmonic in series with a condenser 11. The desired harmonic frequency output may be taken from the circuit 10 or, if the value of the condenser 11 is selected in such a manner that in conjunction with the tuned circuit 10 it acts as a series resonant circuit to an undesired lower harmonic, the output may be taken directly across the resistance 9. In a modification, Fig. 2, the modulated carrier frequency is applied by means of a tuned circuit 2 to two amplifying valves 5a, 5b connected in push-pull, and the output circuits of the valves include tuned circuits 12a, 12b coupled to secondary windings 13a, 13b in series with variable condensers 14a, 14b and piezo-electric crystals 7a, 7b ; symmetrically positioned taps on the secondary windings being connected together and to the cathodes of the valves. The junction points between the variable condensers and the crystals are connected together through a centre-tapped winding 16 coupled to the coil 17 of a tuned circuit 18, which is shunted by the diode 8 and load resistance 9, the latter being shunted by a condenser 1 and circuit 10 tuned to the desired harmonic. The two crystal circuits are so adjusted that each acts to pass only one side band.

Title: Improvements relating to hydraulic motors
IPC: F03C1/34
Filed: 1960-01-23
Abstract: 890,592. Inertia governors. BUDZICH, T. Jan. 23, 1960, No. 2546/60. Class 57. [Also in Group XXIX] An hydraulic motor comprising a stationary cylinder barrel 10, Fig. 1, a plurality of parallel bores 14, reciprocating pistons 16 and a cam-plate 18 rotatable by the pistons to rotate a load 26, includes a valve plate 30 controlling liquid flow into and out of the cylinder which is rotated by an independently-operated control 43 so that the speed of the load may be maintained in a fixed relationship to the speed of the control irrespective of the load. The valve plate 30 having the usual arcuate ports 35, 36, Fig. 3, is formed with an arcuate groove 60 which together with a pin 59 and a shaft 55 splined to the cam-plate 18 permits adjustment of the valve plate with respect to the cam-plate to vary the torque output of the motor. As shown in Fig. 3, with the principal axis 64 of the cam-plate adjusted at, e.g. 45 degrees with respect to the axis of symmetry 34 of the valve plate 30, the motor develops half maximum torque. On, e.g., a sudden reduction in load, the load and cam-plate will be accelerated by the excess motor torque to increase the out-of-phase angle between the axes 64, 34 and so reduce the torque output of the motor to match the reduced load and retain the speed relationship the same. The control 43 may be a constant speed control or programmed for varying speed. It may be either electrically, hydraulically or manually driven. On, e.g., a sudden increase in the speed of the control 43, the axis 34 will approach the axis 64 to increase motor output whence the cam-plate and load will accelerate until the speed of the load again matches the control speed.
