Abstract: 365,592. Glass manufacture. ZAPPERT, E., 55, Chancery Lane, London.- (Dichter, J. ; 4, M³nz Strasse, Berlin.) Oct. 15, 1930, No. 30813. [Class 56.] Forming articles from tubing.-Relates to the formation of bottoms on glass tubes by a machine of the kind in which sections of tubing, each having the length of two finished tubes, are heated in the middle, drawn apart, and the heated ends shaped as required. According to the invention, the operations of melting, drawing-apart, and finishing are performed at a number of stations, the heating of the tubes being effected at two or more stations. The machine comprises wheels or rollers a which support and rotate the glass tubes g and provide a number of working stations I .. VI. The tubes are fed on to the rollers, and are lifted from one station to another, by any suitable devices. Burners c, g are provided for heating [the tubes, and abutments b are provided for preventing the tubes from moving laterally. A tube is heated at stations I and II and arrives at station III with the heated zone of glass in a plastic condition. At this station, oblique rollers z rest on the tube and draw the ends apart in the known manner until they are stopped by the abutments b. A constriction is thus formed in the middle of the tube which is severed by the burner f at station IV. The two short tubes are then transferred to station V and the closed ends are flattened by laterally movable plates p. If rounded bottoms are required, as when making test tubes, a station VI is provided in which the abutments bare replaced by blowheads k. The tubes are pressed against the blowheads by oblique rollers z<1>, and the bottoms are blown to a rounded shape by compressed air supplied to the blowhead, through pipes r.

Title: Pulsed columns for use in physical and chemical reactions
IPC: B01D15/00
Filed: 1964-08-04
Abstract: 1,070,101. Pulsating liquid contact columns. STAMICARBON N.V. Aug. 4, 1964 [July 26, 1963; Feb. 17, 1964], No. 30986/64. Heading B1F. Liquid contained in a column 1 is partly supported by a rubber diaphragm 3, whose other side partly encloses an air cushion 21, 15 which is intermittently supplied with compressed gas so as to cause the liquid column to vibrate at its resonant frequency. Diaphragm 3 has a reinforced centre 6 which is connected by ball-and-socket joints and rod 9 to a slide valve 8. A supply of compressed air to conduit 13 causes downward movement of diaphragm 3 which moves valve 8 to cover rectangular port 10 and uncover rectangular port 11, whereby the pressure in space 21, 15 is released via conduit 19, allowing the diaphragm to move upwards to begin a new cycle. The amplitude of the movement is determined by the volume of air supplied through valve 20, and is observable as pointer 24 moves in transparent tube 26. Chamber 15 contains air, open to space 21 at 14, over oil 16. The oil level 18 is varied to adjust the total air cushion volume and hence the frequency of the diaphragm movement. The pulsation may be sinusoidal, or by opening valve 22 wide and closing down valve 20 saw-tooth pulsations are produced, liquid in the column rising slowly, falling quickly. Fig. 2 (not shown) illustrates an arrangement in which the diaphragm movement pivots a lever which alternately opens inlet and outlet valves supplying air to and releasing air from the cushion behind the diaphragm. The outlet valve acts also as a pressure release safety valve. Figure 3 (not shown) illustrates a diaphragm pulsator as described on a liquid-liquid contact, countercurrent flow, ring-packed extraction column, which may be used to extract nitrolactam from nitrobenzene using ammonia. Figures 4a, 4b (not shown) illustrate arrangements for use with columns containing liquid with quantities of gas bubbles (e.g. CO 2  produced by reaction between liquids in the column), the diaphragms being connected to the columns by bodies of liquid containing no gas bubbles.

Patent GB-656762-A (GB)
Title: Improvements in or relating to electric motor controllers
IPC: H02P1/18
Filed: 1948-12-02
Abstract: 656,762. Controllers. WEST & CO., Ltd., A:. SMITH, M. A. CLEMENT-, and COUPAR, J. Dec. 2, 1948, No. 31246. [Class 38(iii)] Relates to means for preventing a too rapid acceleration of an electric motor. A master controller 2 for a series motor 1 is movable by means of a pedal 3 through a yieldable transmission device comprising a spring 4a. The movement of the controller is retarded by an eddy-current brake comprising a disc 5 and a coil 6 which is energized in accordance with the motor-current. If the retarding-force exerted by the disc 5 is small, the movement of the controller will closely follow that of the pedal, the spring 4a acting substantially as a solid coupling. If the braking-force increases, however, the spring will yield and continued movement of the pedal will have little effect upon the advancement of the controller. At a predetermined current a coil 8a closes contacts 8b to short-circuit an adjustable resister 7 in series with the coil 6. A ratchet device 9 allows the controller to rotate freely in the decelerating direction without moving the disc 5; the position of which may be adjustable relative to the magnetic field. The Provisional Specification refers to the provision of more than one current limit relay, means for entirely stopping the master controller when the motor current exceeds a given value, and energizing the brake coil from a constant voltage supply.

Title: Improvements in and relating to automatic gas valves
Inventor: EVES ERNEST WILLIAM
IPC: F23N5/10
Filed: 1953-11-11
Abstract: 783,699. Fluid-pressure servomotor-control systems. PERL CONTROLS, Ltd. Feb. 11, 1955 [Nov. 11, 1953], No. 31277/53. Class 135. An automatic gas valve has a main valve 4 actuated by a diaphragm 5 the pressures across which are balanced or unbalanced by means comprising a shuttle valve 15 for connecting the space 6 via passage 20 either to the space below the diaphragm or to an atmospheric vent 18, and a flame failure responsive relay 11 which automatically effects displacement of the shuttle valve to its pressure balancing position and closes a valve 34 for the pilot gas supply 37 when it is de-energized on flame failure, movement of the shuttle valve to its venting position being dependent on re-establishment of the pilot gas supply and re-energization of the flame failure relay, the pilot valve being opened manually and held open by the relay: Gas at 2 passes via 7, 8 and bleed 50 to space 48 to lift diaphragm 23. Because of lost-motion between valves 22, 15 valve 22 is lifted off its seat 21 to abut nuts 24 clamping the diaphragm to stem 16 of valve 15, without lifting valve 15 from its seat. On depressing button 28 lever 26 pivots about the end of rod 16 and opens pilot burner valve 34 and brings armature 43 adjacent a flame failure electromagnet 44. On lighting the pilot burner and energizing the magnet, valve 34 is held open and button 28 can be released. Pressure in space 48 acting on diaphragm 23 now lifts valve 15 from its seat 14 and presses it on seat 17 because the lever 26 no longer prevents upward movement of stem 16. The chamber 6 is thus closed to gas pressure at 8 and opened to atmosphere at 18 so that pressure below the diaphragm 5 opens the valve 4. The degree of opening of valve 4 may be controlled by a thermostatically controlled valve in vent 18, the space 6 being open to the gas supply via a bleed 9. On failure of the pilot flame the magnet allows springs 46, 35 to close the valve 34 and downward movement of lever 26 moves valve 15 on to its seat 14 to close valve 4. Should the gas pressure fall below a predetermined value the diaphragm 23 falls and re-seats valves 22, 15 which causes the closing of valves 4, 34. In a modification the button moves the magnet and pilot burner valve directly, release of the button closing the pilot valve and opening a diaphragm valve in series with valve 22. Valve 15 may comprise two parts spring-loaded apart. In a further modification the diaphragm 23 and valve 22 are omitted while in another embodiment the valve 15 is in two fixed portions seating on the ends of passage 19, is connected to a diaphragm carrying the armature, the space at the top of the passage 19 beneath the diaphragm leading to the vent, and the valve 34 is lever operated with lost-motion on an extension of the stem 16 to control the passage 14 leading to the pilot burner.

Abstract: 1,019,245. Electric meters. HONEYWELL Inc. Aug. 16, 1962 [Aug. 21, 1961 (2)], No. 31510/62. Heading G1Q. [Also in Divisions H2 and H3] An overload protective arrangement comprises at least one tunnel diode connected in series with the protected device, e.g. a galvanometer coil 10, and means responsive to the voltage drop across the diode or diodes to provide a shunt path around the device. In Fig. 1, when the current through the coil 10 reaches a predetermined value, the voltage across one or both of opposed seriesconnected tunnel diodes 6, 7 suddenly increases. This limits the current through the coil 10 and increases the voltage across the series circuit to a level such that one or both of parallel diodes 4, 5 become conductive causing a fuse 3 to blow to interrupt the circuit. In Fig. 4, (not shown) on the current through the coil reaching the predetermined level, the sudden increase in voltage across a tunnel diode renders a shunt transistor conductive to short circuit the coil.
