Patent GB-545399-A (GB)
Title: Devices for operating or transmitting code signals
IPC: H04L15/22
Filed: 1941-03-27
Abstract: 545,399. Electric signalling systems. LONDEX, Ltd., BROWN, W. S. F., and STERN, W. March 27, 1941, No. 4116. [Class 40 (i)] In a transmitter for sending a pre-arranged code signal the length of each signal element is measured by the period during which a stepping switch remains in its successive positions, this being governed by the discharge of a condenser through an appropriate resistance. The signalling circuit 1, 2 is under the control of a relay 5 which, as shown, is energized in the odd positions of the switch 12. The stepping magnet 13 is controlled by a relay 15 which interrupts its energizing circuit but is held for a variable period by the discharge of the condenser 16 through one of the resistances 17, 18, 19 according to the position of the switch. These resistances are interchangeable as well as adjustable to determine the lengths of the elements of the code signal.

Title: Apparatus to automatically raise a platform supporting a pile of sheets
Inventor: KING CARL GUSTAVE
IPC: B65H1/18
Filed: 1959-02-05
Abstract: 915,022. Feeding sheets. ROTAPRINT Ltd. Feb. 5, 1960 [Feb. 5, 1959], No. 4141/59. Class 100 (1). Pile tables.-In apparatus for raising a platform for supporting a pile of sheets, the raising mechanism is controlled by an air pressure-responsive device, and the pressure in this device is controlled by a feeler engaging the top of the pile. As shown, sheets are fed from the top of a pile 26 on a platform 17 by suckers 25 which forward them to a rotary offset printing-machine, and the platform is raised to keep the top of the pile at a substantially constant level by chain means operated intermittently by a vertically reciprocating pawl 10 acting on a ratchet-wheel. The pawl 10 is reciprocated through a crank lever 9, a bar 1, a second crank lever 3 secured to a shaft 4, and a lever which is secured to the shaft 4 and rocked by a cam secured for rotation with the impression cylinder of the printing-machine. Depending upon the position of the cam, a spring 18 moves the bar 1 to the left to lower the pawl 10, and the cam moves the bar 1 to the right to raise the pawl and operate the pileraising mechanism. Movement of the bar 1 to the left is prevented when a stop-lever 19 is in the raised position shown, since it lies in the path of a projection 2 on the bar 1. The lever 19 is pivoted to the rod 21 of a piston 22 in a cylinder 23 which is connected by a pipe 34 to a suction line 33. The line 33 is connected to an adjustable device 35 having a nozzle 32. The nozzle 32 is closed by a flap 31 on a pivoted feeler lever 29 when the height of the pile 26 is depleted by a predetermined amount, so that suction builds up in the pipes 33, 34; the piston 22, rod 21, and lever 19 are then lowered, and the bar 1 can be reciprocated to cause the pile to be raised. The suction line 33 can be so connected to the suction system, that the lever 19 will not be lowered if the suckers 25 fail to pick up a sheet.

Title: Improvements relating to pre-payment meters
IPC: G07F15/08
Filed: 1932-02-12
Abstract: 393,369. Prepayment mechanism for meters. HORNBY, R. and WRATTEN, E. H., 7, Carlisle Street, Soho, London. Feb. 12, 1932, No. 4240. [Class 27.] Price-changing mechanism.-In prepayment meters wherein the return of the prepayment mechanism is permitted step by step by an escapement device so that the scale of payment is determined by the number of steps permitted for a given movement of the meter mechanism actuating the escapement device, one member of the escapement device is interchangeable to permit of different numbers of steps while all the remaining parts of the mechanism remain unchanged. The prepayment mechanism set forward bv a coin is returned to zero bv a spindle 2, Fig. 1, driven by gearing 11, 12, 13 from a spindle 10 rotated by a spring under the control of an escapement. The escapement comprises a wheel 8 on the spindle 10 having two concentric rows of staggered pins 9 cooperating with a notched disc 3 driven from a meter spindle 1. For varying the price, the disc 3 is replaceable by another disc of the same size but with a different number of notches, the disc being held in working position by a knurled nut 14 passing through and carried by one arm 15 of a crank lever. The other arm 15a, Fig. 7, of the lever is slotted and engages the end of a slidable rod 16 disposed parallel and close to the spindle 10. When the arm 15 is raised for the disc 3 to be changed, the rod 16 is moved to the left and a stop 17 thereon engages a collar 18 on the spindle, and moves the spindle axially against the action of a spring 20. This disengages the pin wheel 8 from the disc 3, and, at the same time, the spindle 10 is prevented from rotating by the friction between the stop 17 and collar 18. In a modification, Fig. 10, the meter has a changeable toothed wheel 21 which engages one arm of a rocking lever 23, the other end of which carries detents 24, 25 co-operating with the pins 26a of a pin wheel 26 which is connected to the prepayment mechanism.

Title: Process and device for the automatic continuous injection of a fluid adjuvant into a stream of a different fluid
Inventor: DUMOULIN GEORGES
IPC: F04B7/02
Filed: 1969-01-24
Abstract: 1,245,165. Reciprocating pumps. SOC RHODIACETA. Jan.24, 1969 [Jan.26, 1968], No.4303/69. Heading F1A. In a device for the automatic injection of a fluid adjuvant supplied from a resevoir 13 into a stream of a different fluid contained in a channel 15 the pressure in the cylinder 1 or 2 about to commence discharge is increased so as to be greater than or equal to the pressure of the discharge of the other piston. In one embodiment as shown in Fig. 1 as the piston 4 is completing its discharge stroke the piston 3 has already begun its discharge stroke before actual injection from the cylinder 1 occurs. In operation, while the piston 4 is on its descent it triggers the contact 24 to start the descent of the piston 3 which builds up pressure until the constant pressure device 17 triggers the relay 18 to simultaneously change over the value 11, stop and reserve the motor controlling piston 4 and open the valve 27. A simular set of operations occur when the piston 3 is on the descent thus completing the cycle, and hence no interruption or variation in pressure takes place in the injection of the adjuvant. In a modification Fig. 2 (not shown) a common reversible motor (30) with a speed variator (31) is provided to move the pistons (40), (41) simultaneously and in opposite direction and a nitrogen feed (36) is connected to the feed line 14 to establish the desired pressure in the cylinders 1, 2 before the injection phase. A three way valve (37) replaces the valve 27 to allow the channel 14 to be fed either by adjuvant or nitrogen.

Title: Improvements in and relating to the treatment of sulphur
IPC: C01B19/02
Filed: 1959-02-11
Abstract: Impure sulphur is rapidly heated through the plastic range, preferably 160 DEG -370 DEG C., by mixing with a relatively large body of liquid sulphur at a temperature above the plastic range and subjecting the mixture to fractional distillation.  The process may be applied to the purification by distillation of sulphur in sulphur-selenium anode sludge produced in the electrolytic refining of nickel sulphide.  As shown, impure sulphur is delivered tangentially to one or more bubble tray units 25 (Figs. 2 and 3, not shown) in a distillation column 10 having a reboiler 34 from one or more steam-jacketed inlet pipes 14-16 at a temperature of 120-162 DEG C., preferably 120-154 DEG C., and is mixed with, for example, 5-20 times its volume of reflux so as to raise the temperature rapidly above 260 DEG C.  Sulphur containing concentrated impurities is periodically removed through steam-heated bottoms cooling tank 62 while <PICT:0889037/III/1> sulphur vapour is passed through condenser 17.  Condensed sulphur, e.g. at 370 DEG C., is passed through reflux tank 18 and is then partly recycled as reflux via line 19 and partly passed to sulphur quenching and surge tank 21 (Figs. 4 and 5, not shown) via line 20, while uncondensed sulphur vapour is passed through vent condenser 60, wherein the vapour is cooled to below 150 DEG C., and vented wash tower 61, residual gas being passed to the atmosphere. The condensed sulphur is rapidly cooled in tank 21 to below 160 DEG C., e.g. to 120 DEG C., by 10-20 times its volume of sulphur which is recycled between tank 21 and a waste-heat boiler comprising a heat exchanger 48 and a liquid-vapour separator 52. Tank 21 is provided with a steam coil to melt sulphur when starting up. Cooled liquid sulphur is passed through one or more of lines 55 to water-cooled trays in solidifier 24.  The heat exchange medium for reboiler 34 and condenser 17 may be a fused mixture of sodium nitrate and nitrite.  The process may be carried out in the presence of nitrogen.
