Title: Improvements in or relating to railway route setting apparatus
IPC: B61L25/06
Filed: 1957-06-26
Abstract: 864,030. Route-setting apparatus. SIEMENS & HALSKE A.G. June 26, 1957 [June 26, 1956], No. 20226/57. Class 105. Route selection is effected by operating appropriate push-buttons whereby details of the selected route registered in terms of a binary scale (positive or negative magnetization) on a high-speed rotary drum are compared with similarlyregistered existing points settings, signal aspects and track occupancies and the setting is effected by the difference between registrations, subject to no interference by reason of track occupancy or an already set-up conflicting route. Reports of the track occupancy G, points setting W and signal aspects H of the elements of the track system appear as positive or negative magnetization of fixed coils in an initial group 10 and are " read " by a coil attached to a wiper arm rotating in synchronism with the drum 12. This information is recorded in binary code on an " actual " state track on the magnetizable drum 12. The required route is selected by the operation of entry and exit push-buttons on the panel T whereby either a reading coil for this route is rendered operative if the route has been prerecorded on the drum or the route is recorded on a separate drum track from a memory matrix and a reading head for this track is rendered operative. The comparison between the " actual " and " required " states is performed by the computer 13 which, e.g., where a difference exists between an actual and required points setting and the points section is reported clear stores this difference in a separate drum track and when the points have been reported unlocked initiates an operative signal which is transmitted via the selector 11 to the appropriate points setting relay. When the points are changed over to the required state, as reported on the actual drum track, a second signal is initiated by the computer and is passed via the selector to the points locking relay. The required route also includes details of protection which will be required by each of the elements forming the route from neighbouring elements, e.g. safety points. These details are read by the computer acting in conjunction with the electronic device 14 and the necessary setting signals are passed to the controlling relays of the neighbouring elements via the selector 11. When the actual and required states of the elements are identical the precondition exists for the release of the routes entry signal.

Title: Improvements relating to position-finding radio apparatus
IPC: G01S1/02
Filed: 1937-07-21
Abstract: 499,383. Automatic control systems. ROBERTS, O. G. E. July 21, 1937, No. 20266. [Class 38 (iv)] [Also in Group XL] Alignment.-A position-finding radio apparatus for mounting on a vehicle comprises two rotatable loop aerials associated with separate relays and tuned receivers, the loops being rotated into the position of minimum pick-up for two widely separated fixed transmitters by reversible electric motors controlled by the relays, and the position of the vehicle being automatically indicated on a chart by the intersection of two pointers moving synchronously with the loops. In the Figure which shows one of the two symmetrical halves of the apparatus, the pick-up from the frame aerial 10 is fed through the receiver 12 to the galvanometer relay 14 which operates one of the two solenoid relays 19, 20 to close contacts 19A, 19B or 20A, 20B which control the reversible motor 6 by energizing its field windings 21 in a constant direction and its armature 22 in a reversible direction. The motor rotates the frame 10 and pointer 3 by means of the flexible shaft 5 and worm gearings 4, 7 into the position of minimum signal pick-up when the relay 14 opens and stops the motor.

Title: Apparatus for controlling the supply in a can end processing system
IPC: B65G60/00
Filed: 1971-04-19
Abstract: 1335628 Conveying can ends and discharging them from a shoot FLEETWOOD SYSTEMS Inc 19 April 1971 [26 Jan 1970] 20277/71 Headings B8A and B8S Can ends 20 fed from a processing machine (16) (Fig. 1, not shown), to a further processing machine (18), are fed to the machine (18) downwardly through a shoot 34 past spring-urged members 74. These cause a stack to build up, and a further stack builds up in the lower part of the shoot upstream of the entry to the machine (18). Radiation responsive gates 93, 93<1>, operating through peripheral slots in the shoot, respectively control the speed or on-off condition of the respective machines (16), (18). When the system is operating normally, a gap is thus maintained between the two stacks, as shown. The can ends are fed to the shoot 34 by an endless conveyer 38, and are transferred from the latter by the action of suction applied from a manifold 44, and also by the action of rotating feeder wheels 50, 50. In a modification (Fig. 8), the can ends are fed to the shoot 34 by an endless conveyer 124 and a rotating feed roller 132. The drive motor 134 of the conveyer 124, is controlled by a switch 140 which is disconnected when the stack of can ends becomes compressed beyond a predetermined degree. The drag on the roller 132 caused by this condition, tensions a drive chain 136 which drives the roller 132 from the conveyer 124. This causes inward deflection of a jockey wheel 138 thereby operating the switch 140.

Title: A coupling device for use in filling fluid storage cylinders
Inventor: SMITH JOSEPH WILGAR
IPC: F16L37/30
Filed: 1957-06-28
Abstract: 837,921. Pipe couplings. CALOR GAS (DISTRIBUTING) CO. Ltd. June 26, 1958, [June 28, 1957], No. 20484/57. Class 99(1). A coupling device for filling a fluid storage cylinder comprises a pressure cylinder containing a slidable piston, an abutment member for engaging the cylinder outlet and a combined fluid supply nozzle and valve assembly whereby movement of the piston causes relative movement of the abutment member and the nozzle and valve assembly so that the fluid supply nozzle is introduced into the outlet and the valve is operated to allow fluid flow. In Fig. 1 compressed air is fed through the pipeline 3, handle 1, valve 7 into the pressure side of cylinder 5 where it moves a piston 8 to the right to compress a return spring 9 and to cause a V-shaped abutment member 12 to engage the outlet 28 of the fluid storage cylinder. Fluid nozzle 21 enters the orifice 31 and continued sliding movement of nozzle 21 in bushing 22 compresses return springs 25 and allows fluid, supplied via pipe 20 and member 26 to pass through radial apertures 23 in the nozzle 21 into the cylinder outlet. In another embodiment, Fig. 2, compressed air is fed through pipe 52 and thumb operated tap 53 into the pressure side of cylinder 37 to move a piston 49 to the left to compress return spring 50. Rigidly secured to piston 49 is a tubular piston rod 40 through which fluid is supplied to a sliding assembly 41. The hook of member 34 engages the storage cylinder outlet 28 and further movement of assembly 41 causes nozzle 42, Fig. 4, to enter orifice 31 whereafter nozzle 42 retracts against spring 48 thus uncovering apertures 47 to allow fluid to pass from the tubular piston rod through chamber 46 and nozzle 42 into the cylinder outlet.

Title: Improvements in or relating to television receivers
IPC: H04N5/21
Filed: 1962-05-29
Abstract: 979,726. Radio-receiving circuits; automatic gain control; television. MARCONI CO. Ltd. May 29, 1962 [July 28, 1961], No. 20609/62. Headings H3Q, H4F and H4L. In a television receiver for negatively modulated signals interference with the automatic gain control and synchronizing circuits caused by noise is prevented. Video signals, in which the sync. pulses constitute the most positive part of the signal are taken from the anode of a video amplifier V 3  and applied via resistor R 14  and capacitor C 7  to the suppressor grid of a pentode V 2 . This is provided with grid leak bias by means of resistor R 15 , the suppressor/anode path acting as sync. separator and separated sync. pulses appearing on lead F in the anode circuit. Part of the signal is also taken from the anode of video amplifier V 3  via a potentiometer comprising resistors R 10 - R 13  and applied to the common grid of a double pentode V 1 A, V 1 B in which the valve V 1 A acts as a gated A.G.C. valve. Its anode is supplied with positive going line flyback pulses over capacitor C 4 , the bias on the cathode being set by resistors R 1 -R 3  and the grid bias being such that the tips of the sync. pulses on the grid cause conduction, so that there is generated on line B an A.G.C. potential in dependence upon the signal strength. The grid bias and thus the contrast is adjustable by means of a potentiometer R 12 . The video signal available at the join of resistors R 10 , R 11  is also applied to the suppressor grid of pentode V 1B  via a potentiometer comprising resistors R 7 , R 8  and by-pass capacitor C 5 , which applies a suitable D.C. bias and at the same time emphasizes the higher frequency components of the video signal, and more especially sinc. and noise pulses, at the suppressor grid. The arrangement is such that with the maximum allowable signal applied to the receiver the tips of the sync. pulses are just unable to cause conduction in the valve V 1B . The more positive noise pulses, however, cause conduction and the resultant negativegoing pulses in the anode circuit are passed by a capacitor C 2  to the suppressor grid of the AGC valve V 1A  and inner grid of sync. separator V 2 , whereby these valves are biased toward cut-off during noise pulses. A capacitor C 3  connected to a source of negative-going line flyback pulsses compensates for the positive-going line flyback pulses reaching the suppressor grid of the valve V 1A  from the anode via the anode to suppressor grid capacity.

Title: Fractionator control system for reboiling narrow boiling range liquids
IPC: C07C7/04
Filed: 1971-04-19
Abstract: 1329175 Control of fractional distillation columns UNIVERSAL OIL PRODUCTS CO 19 April 1971 [30 Jan 1970] 20764/71 Heading B1B A liquid mixture such as a mixture of ethylbenzene, p-xylene and m-xylene, is separated into a more volatile, overhead fraction (pure ethylbenzene) and a less volatile, bottoms fraction (p- and m-xylene) of narrow boiling range by introducing the feed mixture through line 4 into fractionating column 1 the bottom of which is connected by line 20 and controlvalve 27 to a reboiler 31 wherein a constant flow of the bottoms is at least partially vaporized, and the vapour (and liquid) is passed to the lower section of column I through line 34 which contains a flow-orifice 35 connected to controller 37 whereby the valve 39 which regulates the supply of heating medium to the reboiler through line 32 is controlled. Bottoms product flows out of the system through line 21, the rate being controlled by valve 22 actuated by the liquid-level in the lower section of the column. Ethylbenzene vapour flows from the head of the column to condenser 6; and the condensate divides into two parts, one of which is refluxed to the column through line 9, while the other part leaves the system through line 10 and valve 12 which is controlled by composition analyser 17 to ensure the purity of the ethylbenzene product. When an excessive amount of vapour is generated within reboiler 31, the pressure-drop across orifice 35 is increased and controller 37 acts to reduce the heat input to the reboiler. Similarly, when the pressure-drop across orifice 35 falls off, this is indicative of a loss of vapour generation within reboiler 31; and controller 37 will make a compensating adjustment to the flow of heating medium in line 32. The reboiler 31 as shown is a simple heat-exchanger; but a direct-fired furnace may be employed, the flow of fuel being controlled by valve 39. Modified control arrangements are described for a fractionation wherein it is desired to obtain a high-purity bottoms product; a composition signal being sent from the lower section of the column to controller 37 (Fig. 2, not shown) or the valve 22 (Fig. 3, not shown). Analyser 17 may be of the chromatographic, infra red, or mass spectrometer type; or a boiling point monitor, dielectric constant analyser, or temperature controller may be substituted. The line 34 may contain a bend, and in this case the orifice 35 may be replaced by a pressure-sensing device located on the outside radius of the bend.
