Title: Improvements in or relating to carrier wave modulation systems
Inventor: SOSIN BOLESLAW MARIAN
IPC: H03C1/60
Filed: 1962-04-10
Abstract: 983,116. Amplitude modulation systems. MARCONI CO. Ltd. Nov. 21, 1962 [April 10, 1962], No. 13780/62. Heading H3R. In a vestigial sideband modulation system, to increase the vestigial sideband, the outputs of two double sideband modulators 1, 2, DSBM are combined in carrier phase quadrature by a directional coupler UDC, and the modulators each fed by modulations in relative phase quadrature derived from a video directional coupler VDC, with modulation supplied in phase (or antiphase) to it from an input terminal IN. The input on lead 1 to VDC is fed to modulator 2DSBM with a characteristic increasing with rise in frequency, from zero to one half the input level and fed to modulator 1DSBM with a characteristic falling to one half the input as the frequency increases and the two modulation inputs to modulators 1DSBM and 2DSBM are in phase quadrature. A similar result is produced by the input 2 but with the rise and fall characteristics transposed. A double sideband results as output from UDC but if a low-pass filter LPF is inserted in one input to the coupler VDC and a compensating phase shift network PDN (without filter) in the other, a vestigial sideband output results from UDC. The couplers UDC and VDC may both be of the coupled line type. Alternatively, the carrier C1 may be applied in relative quadrature phase to the modulators and their two outputs directly combined (i.e. coupler UDC dispensed with).

Title: Improvements in or relating to cooling systems for motors of large vehicles
IPC: F01P7/16
Filed: 1934-05-08
Abstract: 442,505. Radiators for motor vehicles. SOC. ANON. DES USINES CHAUSSON, 35, Rue Malakoff, AsniÞres, Seine, France. May 8, 1934, No. 13921. Void [Abridged as open to inspection under Sect. 91 of the Acts, Nov. 10, 1934]. [Class 29] [See also Group XXIX] In a cooling system for the engines of large vehicles, several radiators are arranged in parallel water circulation circuits and are placed successively in operation as the temperature of the cooling water rises and out of operation as the temperature of the water falls. Four radiators a<1>-a<4>, Fig. 1, have separate inlet pipes g<1> and separate outlet pipes e<1> which open into a tank h from which the cooling water is circulated by a pump f through the engine jacket. At starting, the water is returned to the tank through a byepass i. As the temperature of the water rises, a thermostat 10 closes a valve k in the byepass and opens a valve j in one of the radiator inlet pipes. As the temperature of the water rises further, valves in the other inlet pipes are opened in succession. A radiator inlet valve j and byepass valve kare actuated by a lever 14, Fig. 4, pivoted to a stem 15 between the valves and freely mounted on a shaft 12 carrying an arm 13 with projections 13a, which engage the sides of the lever as a thermostat t expands beyond or contracts below a certain point. As the thermostat expands or contracts, a slotted member 8 is pressed against a lever 11 secured to the shaft 12 and tends to rotate the shaft against the resistance of a leaf spring 23 engaging another lever 19 on the shaft. A pin 20 on the lever 19 slides on oppositely inclined surfaces of a projection 22 on the spring thus ensuring a quick movement of the shaft and valve lever 14 in one direction or the other.

Title: Improvements relating to the purification of distillation gases
IPC: C10K1/04
Filed: 1929-05-06
Abstract: 311,404. Cheminova Ges. zur Verwertung Chemischer Verfahren. May 11, 1928, [Convention date]. Condensing processes; materials for purifying. -In removing naphthalene from distillation gases, particularly that remaining after the usual washing with tar oils, by means of a small quantity of a volatile solvent such as xylol, alcohol, or tetrahydronaphthalene, the gas is first charged with so small a quantity of solvent that supersaturation does not occur even at cold places in the pipe system. The gas is then compressed to such a degree that separation of solvent and naphthalene occurs at the cold places. On reduction of pressure for use the gas is undersaturated and further separation avoided. The process is applicable to gas which is supplied under pressure to long distance supply mains, solvent being introduced before compression of the gas.

Title: Improvements relating to card or like indexing, sorting, tabulating and like apparatus
IPC: G06K21/02
Filed: 1929-05-07
Abstract: 327,610. Bacchus, B. C., and Taylor, E. W. May 7, 1929. Sorting cards.-Relates to means for raising a single selected card, tablet or like element, after it has been released from a pack of such elements, irrespective of the position it may occupy in the pack. The cards are retained in the pack preferably by means described in Specification 281,949 wherein the desired card is released by rotation of rods of suitable cross-section into a position in which they can pass through restricted parts in gaps formed on the edge of the card and corresponding to different numerals, letters or the like. The cards 1, Fig. 1, have gaps with restricted entrances 3 to correspond to the characteristic of the individual card, the remaining gaps 4 being parallel-sided. Release is effected by giving a quarter turn to appropriate rods 5 operated by a keyboard. Each card is supported at both ends by shoulders 13 on thin metal frames 6 which can slide vertically on horizontal guide-bars 7 and are urged upwards by springs 8 arranged between lugs on the slides 6, and plates 10 threaded on fixed bars 11. Lugs of individual groups, say of five slides, are preferably staggered as shown by amounts corresponding to the slide thickness, to permit the employment of a useful spring diameter. The slides are normally held inoperative by a series of pivoted levers 16 each of which is held against lugs 15 on the ends of three, or other number of slides by springs 18 stronger than the springs 8 and connecting the levers to plates threaded on fixed bars 21. The springs are staggered in groups of three as shown. The levers are successively raised to disengage the slides by opposite rotation of parallel shafts 24 carrying a series of cams 23, one engaging each lever, angularly displaced relatively to each other as shown. The shafts 24 are geared together through pinions 26, 27, one of the pinions 27 being freely mounted on a shaft 48, their rotation being effected by operation of a ratchet hand-lever 33 through a cross-shaft 32, bevel gearing 31 and a pinion 28. The shaft 29 carrying the pinion 28 passes through to the rear end of the cabinet and operates similar gearing there, so that movement of the lever 33 causes the shafts 24 to be rotated step by step from both ends and in opposite directions. Means for positively returning a slide which may have jammed in the raised position, comprise a hand-lever 52 operating bevel gearing 50 to rotate the shaft 48 and driving, through pinions arranged behind the pinions 27, further pinions mounted on bushings on the shaft 24 behind the pinions 26 and associated with cams 45. Movement of the lever 52 causes the cams to raise levers 43, thereby lowering the guidebars 7 and positively returning any slide which may have jammed. The shaft 48 passes through to the rear of the cabinet where the gearing is duplicated so that the bars 7 are lowered at both ends, return being effected by springs 40.

Title: Improvements relating to marking machines
IPC: B41K3/00
Filed: 1945-06-06
Abstract: 593,104. Marking or embossing machines. ACKWORTHIE, Ltd., J., WRIGHT, E., and WALKER, A. C. June 6, 1945, No. 14230. [Class 100 (ii)] [Also in Group XXII] In a machine for impressing names, etc., upon flat or round articles wherein the workpiece is supported on a table raised to bring it against a marking die which is moved across the work by a reciprocating slide, the diecarrying slide and the table are operated by fluid-pressure actuated pistons, and the supply of pressure fluid to the piston cylinders is controlled by a single member such as a lever. The work-table 18 is adjustable in guides 22 according to the thickness of the work by a screwed spindle 24 the lower end of which is connected to the piston 26 of a cylinder 27 operated by compressed air. A second cylinder 13 operates to rotate a slotted link 7 connected by gears 5 to a spindle 4 in the presshead 3. A pinion 14 on the spindle 4 engages teeth 15 on the die-carrying slide 16 to move the die across the work-piece. If the latter is flat, a circular die 17 is employed which may be rotated positively by a rack and pinion 19, 20, but a flat die may be used if an article which can roll is to be marked. To operate the machine, a treadle 29 or a hand-lever is provided. The treadle 29 is normally held raised by a spring 33, Fig. 4, and is connected by a spring 34 to a rotary-valve arm 40 movable between stops 41. Initial depression of the treadle opens the valve 35, Fig. 12, to admit fluid pressure through a pipe 37 to the cylinder 27 and raise the table 18. Further movement brings the treadle into contact with a combined exhaust and admission valve 50, 47 so as to close the exhaust valve 50 and open the valve 47 to admit fluid pressure from the pipe 37 to the bottom of the cylinder 13 and thus move the die across the work. Upon its release the treadle is raised by the spring 33 and operates the valve 35 to cut off the pressure fluid and connect the cylinder 27 to exhaust. At the same time, the pressure fluid causes the valve 47 to close and the valve 50 to open thus exhausting the bottom of the cylinder 13. The table 18 thus falls and as it nears its lowered position an arm 60 on the spindle 24 engages the exhaust valve 56 of a combined valve 56, 55 similar to the valve 50, 47 and disposed in a pipe 54 connecting the top of the cylinder 13 to the pressure-supply pipe 37. Pressure-fluid is thus admitted to the top of the cylinder 13 thus causing the die-carrying slide 16 to be returned to its initial position. A valve 38 is provided in the supply pipe to the cylinder 27 to adjust the pressure.
