Title: Improvements relating to direct current track circuits for railway signalling systems
IPC: B61L1/18
Filed: 1955-11-03
Abstract: 823,045. Railway signaling track circuits. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., DUCKITT, H., and TILLOTSON, P. Oct. 26, 1956 [Nov. 3, 1955], No. 31463/55. Class 105. In a D.C. track relay circuit having one, viz. 11, track rail continuous as the return for the traction A.C. current, the other rail 12, being divided into sections by insulating joints 13, 14 the current feed set comprises a feed full-wave rectifier 31, 32 fed from an A.C. source 18 as through a transformer 17 and connected at its output terminals across the rails 11, 12 in series with a choke 22 designed to limit the flow of A.C. of traction current frequency and having across the said output terminals a low resistance 20 as a low-impedance path for currents of traction current frequency; and a reference fullwave rectifier 33, 34 preferably fed by the source 18 and means such as a relay 26 connected between the positive terminals of both rectifiers for comparing the output voltages of the rectifiers and for disconnecting, as by the relay contact 26a, the feed rectifier 31, 32 from the track rails when the output voltage of the feed rectifier attains a predetermined magnitude in relation to the reference rectifier output voltage whereby the continued operation of the feed set is prevented before the sensitivity of the track circuit to trains entering the section is reduced due to the half-wave rectification taking place in the feed rectifier on account of an A.C. traction current frequency voltage developing across the feed rectifier output terminals. The two rectifiers may be fed from the same transformer having two secondary windings so adjusted that the output voltage of the reference rectifier 33, 34 is normally greater than that of the feed rectifier so that the relay 26 is normally energized and picked up with its contact 26a in the feed circuit closed whereby an increase in feed rectifier output voltage above a predetermined value releases relay 26 and opens the track feed circuit. For proving the operation of the reference rectifier a relay 27 is connected across the output terminals and is arranged to act as a shunt path of low impedance to the A.C. current of traction power frequency to protect the rectifier from increased output due to the traction power frequency currents being half-wave rectified. The pick-up circuit of relay 27 includes a front contact 26c of relay 26 and a front contact 27e in its holding circuit. The relay 27 has a front contact 27b in the track feed circuit so that this circuit is closed only if the reference rectifier set is correctly energized. A back contact 27d of relay 27 is in the pick-up circuit of relay 26 over resistance 30 to be energized by the reference rectifier after an interruption of the feed circuit which relay 26 picks up relay 27 over contact 26c, should the relay 27 have also dropped away owing to the interruption in the A.C. supply 24.

Title: Method and apparatus for the manufacture of glass containers,such as ampoules,injection bottles and the like
IPC: C03B23/11
Filed: 1960-09-13
Abstract: <PICT:0965661/C1/1> <PICT:0965661/C1/2> <PICT:0965661/C1/3> The invention relates to a method of producing, from drawn glass tube containers free from fragments of glass. The tube, as drawn, is cut into lengths and both ends of each length are sealed to keep the interior clean, one end of each length being opened before making containers from it.  As shown, the lengths 2, Fig. 2, severed mechanically, are supported on rollers 9, 10, 11 and located against a stop 15 by a roller 14 while heated by a flame 12 until a roller 13 removes the end portion 3, which may contain fragments, and seal the end of the remainder which is moved against a stop to flatten the sealed end.  The opposite end is then similarly treated, the tube being heated along its length to produce internal pressure and prevent this sealed and collapsing inwards as a result of reduction of internal pressure due to cooling.  Alternatively, the original tube can be severed by melting to produce lengths with smooth ends free from fragments, one or both ends being open and subsequently sealed. The end sealing may be effected in the machine shown in Fig. 8, wherein the tubes 2 from a magazine 21 are fed by a chain 22 to the rollers 9, 10, 11 below, each tube being lifted to feed it to the next pair of rollers by lifting a bar 24.  One end of end tube is sealed in the portion 26 of the machine, the other end in the portion 27. Chucks 30 in a container forming machine, are rotatable about an axis 29. Tubes 21 for feeding to the chucks are mounted in notches in discs 34, 35, rotatable by a motor 33, and are retained by fixed guides 38, 39.  When a feeler 41 detects that no further useful length of tube remains in one of the chucks a switch is closed to energize a solenoid 45 to pivot arms 46, 461 to move a tube 21 outwards into line with the chuck. The feeler arm 41 is pivoted at its centre and spring loaded to allow the tube to descend into the chuck.  The end of the tube so fed has meanwhile been heated by a flame 50 to open it, while the tube is heated by a flame 51 to maintain the internal pressure.

Filed: 1939-12-06
Abstract: 536,432. Type-bar-making machines. LINOTYPE & MACHINERY, Ltd., SCOTT, R. H., GORSE, W. F., and HAYWARD, A. S. Dec. 6, 1939, No. 31611. [Class 100 (iii)] Assembling and distributing matrices.-In machines having means for altering the cycle of the first elevator, so that it moves only between the line-receiving and casting positions, in order to adapt it for hand-composed lines, the elevator-cam 4, Fig. 1, has two alternative tracks located in the same vertical plane, and the camroller 3 of the elevator-lever 2 is caused to follow one or the other by selecting-means operated by hand or automatically. The normal track comprises a high part 5, which raises the elevator to the distributing position, and the alternative track 6 passes beneath it. The roller 3 is guided on to and off the high part by pivoted spring-pressed fingers 7, 8. When the low track is required, the finger 7 is rocked out of the path of the cam-roller by an interponent 13, which strikes a projection on the finger, and the roller moves the finger 8 aside. The interponent can be moved into the path of the finger 7 by a spring-pressed rod 14, shown in plan in Fig. 6, and is normally held out of action by a spring catch 18, which engages a stop on the rod. The catch can be pulled away by a Bowden wire 19 operated from a handle 26. At the end of the cycle, the rod 14 is re-engaged with the catch 18 by a lever 23 operated by the disengagement of the driving-clutch 27. Where the elevator has a rotatable head carrying two lineholding jaws adapted for machine and hand composition respectively, the means for varying the elevator cycle may be actuated automatically. The shaft carrying the rotatable head has an eccentric portion, which, in one position of the head, allows the latch 18 retaining the sliding rod 14 to be withdrawn by a spring, so as to bring the interponent 13 into action. The handcomposing jaw may have a projection adapted to act through a sliding rod to release the catch of the spaceband shifter-carriage.

Abstract: 287,614. Graseby, R. C. Dec. 21, 1926. Pneumatic conveyers.-In a pneumatic conveyer used for delivering material such as powered fuel to a series of storage hoppers of the hind having a main pipe line with a branch therefrom into each hopper, a main valve for each hopper which when open allows material to pass to the said hopper and closes the remainder of the main pipe line beyond the branch to it, and means for closing the branch and opening the main pipe line beyond it when the hopper is filled, the means to actuate a main valve comprises in combination a fluid-actuated first motor operatively connected to the main valve, a valve to control the supply of fluid to the motor, a second fluid-actuated motor to operate this valve, and control means for the supply of fluid to the second motor actuated by the material in the hopper. The main pipe line 1, Fig. 1, is connected to a series of hoppers 6 - - 9 by branches 2 - - 5 which can be closed by disc valves 11, Fig. 2. Each disc valve is connected through arms 12, 12 and a link to a spindle 13 on which is mounted an arm 14 connected to the double-acting piston. 15 of a cylinder 17. The ends of the cylinder 17 are connected by pipes 18, 19 to a dual valve which, with its operating motor, is contained in the casing 20. The valve comprises two pairs of mushroom heads 23, 23 and 24, 24 carried by rods 21, 22 which are moved by a rocking-arm 25, acted on at one end by a second fluid-operated motor comprising a member 26 moving in a chamber 27 and having a tail rod 28. The other end of the arm 25 is acted on at one end by a second fluid-operated motor comprising a member 26 moving in a chamber 27 and having a tail rod 28. The other end of the arm 25 is acted on by a spring-pressed block 29. An air supply pipe 32 opens into the space between two flexible diaphragms 30, 31 extending across the chamber 27, and another supply pipe 33 opens into the chamber above the diaphragm 31. A pipe 34 supplies air to a chamber 35 from which it passes to either of the pipes 18, 19 according to which valve 23, 24 is lifted. The pipe 34 and a pipe 45 are connected to the main air supply pipe 48, and the pipe 33 is connected by a pipe 49 to hand-operated valve 50 on a control board 51. The pipe 32 is connected to a pipe 46 which opens into the pipe 45. The admission of air through the pipe 45 to the pipe 46, or the exhaust of air from the pipe 46, is controlled by valves 44 mounted on a rod 43 connected through toggle linkage 42 to a pivoted arm 40. A spring 39 connects this arm to the upper end of a swinging arm 36 which is arranged within the hopper. When the hopper is filled, the arm 36 is moved over the position shown in full lines in Fig. 5, and this effects the movement of the valve 11. to'close the branch. Movement of the spindle 13 in either direction closes contacts which are in circuit with lamps 54, 55, respectively, on the board 51. Specification 287,613 is referred to.
