Title: Improvements in and relating to railway vehicle axle counting systems
IPC: B61L1/16
Filed: 1957-04-02
Abstract: 874,654. Photo-electric circuits. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd., and EDWARDS, M. E. April 2, 1958 [April 2, 1957], No. 10800/57. Class 40(3) [Also in Groups XIX and XXX] A photo-electric sensing device for sensing the passage of railway vehicle axles for counting comprises a light unit L and photocell unit P and is associated with a circuit which produces a pulse in response to the passage of an axle. Light from a lamp A mounted at one focus of an elliptic reflector r is formed into a parallel beam by a bi-concave lens l, the beam then being reflected from a prism p formed at the end of a rod t of transparent material to pass along the rod whence the beam traverses the top of a rail, or passed through a slot in the rail, to be focused by a lens formed in the end of a second transparent rod w on a photo-sensitive device comprising a selenium photocell n, Fig. 1, adapted when illuminated to bias to cut off a transistor k. When the light beam is interrupted by the passage of wheel of vehicle, the transistor k onducts to energize a high speed relay APE which supplies a pulse to be counted. The photocell may be a photo-transistor or selenium photo-cell.

Title: Operating device for movable members
Inventor: WEBB CHARLES DUNCAN HENRY
IPC: E05F11/06
Filed: 1967-03-08
Abstract: 1,221,062. Operating and locking device for movable members; remotely operated fastenings. C. D. H. WEBB. 5 Jan., 1968 [8 March, 1967], No. 10973/67. Headings E2A and E2M. An operating device for movable members such as doors and windows comprises forcetransmitting means operatively linked to the movable member through a lost motion device and also linked to a locking bolt on the member through a further transmission system which is operated by part of the movement of the force-transmitting means to release and engage the bolt, the other part of the movement being used to move the member. As shown in Fig. 1, a pivotally movable window 11 is supported in a fixed frame 12 and is operable through a flexible drive member which may include a rigid tube-like casing 13 housing a flexible drive cable 14 which can transmit both tension and compression. The casing 13 is terminated adjacent the window 11 in a terminal member 15 fixed to a horizontal part of the frame 12 and the end of the cable 14 carries a forked member 16 for coupling to the window 11. The central fitting 21 consists of three parallel apertures which are housed partly within a hollow part of the terminal member 15 when the window is closed. The central aperture receives a guide pin 22 mounted on a slide block 23 (see Fig. 5, not shown) having a projecting plate 24 adapted to be received by the forked member 16 and coupled thereto by means of a crosspin and the other two apertures receive guide pins 25 carried by the block 23. The ends of the guide pins 25 are connected to flexible force-transmitting members 26 running through bores in the tubular casing parts 17, the other ends of the members 26 being coupled to actuating means for the bolts 19 mounted in the drive units 18 which contain a rack 28 and pinion 29. In a modification, the casings 17 are replaced with tubular channels 33 (Fig. 6, not shown) formed in the window frame 11. The bolts 19 may thus be connected directly to the ends of the force-transmitting members 26 and the drive unit 18 is omitted.

Title: A machine for automatically cutting sections of equal length from bar or tube material with a like cut at each end
IPC: B23Q7/05
Filed: 1960-03-29
Abstract: 885,441. Sawing. WAGNER, E., and WAGNER, F., [trading as WAGNER MASCHINENFABRIK GUSTAV]. March 29, 1960 [April 10, 1959], No. 11013/60. Class 145. In a machine for automatically severing sections of equal length from a bar/or tube by advancing it through clamping means 2, 3 and past a saw 6 or other cutting means up to an adjustable stop 4, a short initial length is cut off first to clean up the face of the first section and the last section of the bar or tube, which is too short to be gripped by the clamps, is ejected by the next following bar 1<SP>1</SP> without contacting the stop. As the bar 1 reaches the stop 4, the stop yields slightly and closes a switch 5 so that clamps 2, 3 close, feed rollers 7-11 are stopped and the saw 6 cuts off a section. When the saw is withdrawn, the clamps open and feed rollers are driven again to repeat the severing process. Forward motion of the bar drives a roller 12 connected by a slipping clutch 14 to cam rings 21, 22 which are prevented from rotating by a locking fin 15 until the end of the bar clears an arm 17 and closes a switch 18. The switch 18 causes the pin 15 to be withdrawn and releases the lowermost bar 1<SP>1</SP> of a pile of bars to the rollers 10, 11 where the bar closes a switch 20 that prevents further bars from being released, for the time being. The rollers 10, 11 advance the bar 1<SP>1</SP> until it contacts bar 1 and closes switch 18 so that the locking pin 15 is released ready to stop the cams 21, 22 after one revolution. The cam rings control tappets 23, 24 operating switches 25, 26 and 27 and the first action is to close the switch 25 so that the speed of advance of the bar 1 is reduced. At a later stage, shown in Fig. 11, the displacement of tappet 24 closes switch 27 and stop 4 is raised out of the path of the last short section of the bar which is then ejected. Thereafter switch 27 re-opens and switch 26 is closed by a second rise on cam 21 to cause the clamps to grip bar 1<SP>1</SP> before it contacts the stop 4 and ensure that only a short section is cut initially. Finally, switches 25 and 26 re-open and the projection 16 on disc 14 is then in engagement with the locking pin 15.

Title: Improvements in or relating to machines for tamping and perforating articles such aspies
IPC: A21C11/12
Filed: 1957-02-18
Abstract: 858,010. Pie-moulding machines. FOOD MACHINERY & CHEMICAL CORPORATION. Feb. 18, 1957 [April 30, 1956], No.11173/60. Divided out of 858,007. Class 87(2). A machine for conveying articles such as pies in single file, has a rotary housing 62, Fig. 4, carrying a plurality of units 64 for tamping and perforating the upper surface of each article in timed relationship with the movement of the article. The housing is mounted on a horizontal axis adjacent the conveyer and carries three tamping and perforating units 64 adapted through gear means to perform an orbital translatory movement on the housing. Each unit 64 has a lower perforated tamping plate 110 that can be forced upwardly against spring means 108, 109 to cause aligned perforating members 121 on an upper plate 122 to extend therethrough. In operation, Fig. 9, a conveyer carries a pie P past the mechanism and as a unit 64 moves into contact with the pie the tamping motion of the plate 110 against the surface of the pie is stopped when a roller 114, Fig. 10, on the plate 110 engages a guide block 116. Further downward motion of the unit 64 then causes the springs 108, 109 to be compressed as the perforating members 121 pass through the lower plate 110 to perforate the upper crust of the pie P. Fig. 10 illustrates the withdrawal of the perforating members 121 from the surface of the pie P, the springs 108, 109, maintaining the tamping plate 110 in contact with the pie until the perforating members 121 have been completely withdrawn. A pair of guide rods 118 and 119 overlie the outer edges of the pie adjacent the tamping mechanism to prevent the pie being raised from the conveyer 50 by adherence of the crust to the tamping plate 110. The pie tamping and perforating mechanism indicated at B in Fig. 1, forms part of a machine in which the pies are fed by a conveyer A past the mechanism B, and are then inserted at station F into cartons which have been erected by a mechanism D and inserted between blocks 133 on an endless conveyer E. The filled cartons then pass through a carton closing and locking mechanism G. The mechanism G, the mechanism D and the conveyer A are described in Specifications 858,007, 858,008 and 858,009 respectively.

Title: Improvements in or relating to the coking of heavy hydrocarbonaceous residues
IPC: C10B55/08
Filed: 1952-05-05
Abstract: <PICT:0734509/III/1> <PICT:0734509/III/2> <PICT:0734509/III/3> A heavy liquid or liquifiable hydrocarbonaceous residue is continuously coked by mixing it with a naphtha diluent boiling from 100-650 DEG F. and with finely-divided seed coke, preferably of particle size 5-250 microns, subjecting the mixture to a liquid phase coking reaction while maintaining it in a highly turbulent state, separating cake from the mixture withdrawn from the coking zone and utilizing at least some of it to provide the seed coke required for the formation of the mixture.  Preferably the coking is performed at 750-900 DEG F. and 1000-3000 p.s.i.g. and the residence time in the coking zone is 5-60 minutes.  Referring to Fig. 1, a crude residuum from line 1, and at the beginning of the process fresh seed coke from a hopper 7, is fed by a pump 3 to line 5 at 1000-3000 p.s.i.g. which is also fed via line 9 with a slurry of ground product coke in recycle bottoms and heavy naphtha obtained from the coking process.  The mixture flows through a fired coil 11 heated to 800-850 DEG  F. at 4-10 ft./sec. whereby it is maintained turbulent.  The effluent of coil 11 passes to a soaker 17 wherein it is maintained in a highly turbulent state and the coked products are passed through a pressure release valve 21 to a fractionator 23 fed with steam at line 33 to obtain a gas and light naphtha fraction (b.p. below 200 DEG  F.) at line 25, a heavy naphtha (b.p. 200-420 DEG  F.) at line 27, a heating oil (b.p. 430-650 DEG  F.) at line 29, a gas oil (b.p. above 650 DEG  F.) at line 31 and a non-volatile fraction containing seed coke and product coke at line 35.  About 50 to 70 per cent of the mixture in line 35 is passed through a disintegrating device 39 and pump 41 to line 5. The rest of the mixture is passed to a rotary filter 47 having suction applied to its interior and having its outside washed with a stream of product heavy naphtha from nozzle 57. Coke free of heavy bottoms is scraped off the filter 47 and passed via line 61 to a stripper 63 wherein adhering naphtha is removed by steam injected via line 65.  A mixture of wash naphtha and bottoms is sucked from the interior of the filter 47 into a tank 51 from where it is pumped to line 5.  The soaker 17 may have within it (Fig. 2) a draught tube 75 and propeller 77 and may be fed with compressed gas (e.g. product gas) through line 85; the feed from line 15 circulating downwardly through the draught tube 75 and upwardly in the space between the draught tube and the walls of the soaker while at the same time it is given a rotary motion by the propeller 77.  Alternatively the soaker may comprise (Fig. 3) three inverted conical vessels 17a, 17b and 17c; the hot feed being fed tangentially into the top of each vessel at 4-20 ft./sec. whereby a turbulent rotary motion in a downward direction is set up.  The vessels may be in the form of upright cones receiving the feed at the bottom and discharging from the tap.

The two diodes may form part of an integrated circuit carrying the subscriber equipment circuitry. Such a bridge circuit comprising components Z1, Z2, D1, D2 is shown in use with a standard subscriber telephone set in which a receiving amplifier EV and a transmitting amplifier SV are employed, the circuitry JS shown within the broken line being formed as an integrated circuit. The arrangement GA is for metering purposes and a filter circuit TP is used to prevent control pulses for a meter Z from reaching the bridge circuit. Further protection is afforded by a surge voltage diverter UA connected at the input to the subscriber equipment, this diverter having a response voltage which is substantially higher than that of the Zener diodes in the bridge circuit; an impedance L in the filter TP serves as a decoupling resistance between the diverter and bridge circuits. In the absence of any metering arrangement, a separate decoupling resistor must be used. A further less complicated embodiment is described with reference to Figs. 1 and 2 (not shown), in which an impedance in the antiside tone bridge circuit of the equipment acts as the decoupling resistor. Terminals T1, T3 may be provided for the inclusion of a push-button dialling device instead of a rotary dial, the terminals T2, T3 being connected when a rotary dial is used.
