Title: Improvements in apparatus for dispensing liquids
IPC: G01F15/08
Filed: 1960-01-14
Abstract: 882,794. Reciprocating pumps. AVERYHARDOLL Ltd. Jan. 14, 1960 [Aug. 7, 1959], No. 1423/60. Class 102(1). [Also in Group XXIX] In a liquid dispensing apparatus comprising a pump 3, fed under gravity from a tank 1 and discharging through a meter 9 to a pipe 10, to prevent erroneous meter readings when the tank is nearly empty or when a vortex phenomena occurs just prior to emptying, a valve device 5 under the control of a gas detector 16 in the tank bottom is fitted between the pump and the meter. The valve device comprises a main valve member 6 integral with a piston 7 having a calibrated orifice 7b and pilot valve member 15a controlling a duct 7a through the valve 6 and piston 7. The valve 15a is connected to a piston 15 subjected to the pressure prevailing in a Pitot tube 12 opening in the detector 16 opposite to a nozzle 11 connected by a pipe 13 to the pump discharge upstream of the valve 6. If air is present to fill the detector 16, liquid issuing from the nozzle 11 produces in the Pitot tube 12 a pressure greater than that existing in a chamber 5b above the piston 7 to close the valve 15a. Pressure above the piston 7 then builds up to balance pump discharge pressure acting beneath it, whence the liquid which tends to pass to the meter pushes the valve 6 towards closure to cut off the supply to the meter. The liquid then delivered by the pump 3 returns to the tank 1 by a pipe (not shown). If no air is present in the detector 16 the pressure in the Pitot tube 12 falls and the now higher pressure in the chamber 5b raises the piston 15 to unseat the valve 15a. Liquid escapes from the chamber 5b through the duct 7a at a faster rate than it enters through the orifice 7b so that the piston 7 is also raised to open the valve 6. In a modification, the detector 16, nozzle 11, pipe 13 and Pitot tube 12 are replaced by a guided float having beneath it a needle valve which cooperates with the upturned end of a pipe at the bottom of the tank connected to the pump discharge and to the chamber in which the piston 15 slides, so that when the liquid in the tank is insufficient to support the float the upturned end of the pipe is closed and pressure builds up in the pipe to move the piston 15 to close the pilot valve 15a and hence the main valve 6.

Filed: 1965-01-15
Abstract: 1,036,832. Control of motors; transmitting mechanical power. F. SHIBATE. Jan. 15, 1965 [Jan. 23, 1964], No. 1853/65. Headings H2H and H2J. An induction machine 1 is controlled by the combination, in series, in its secondary circuit of a rectifier 3, a D.C. machine 2 coupled to its shaft, and a controlled converter 4. The latter is connected to the A.C. supply 20 through a transformer 5, and has a firing angle control circuit 9 whereby it may operate as a rectifier or an inverter. The magnitude and polarity of the field 23 of the D.C. machine is also adjustable (Figs. 3a, 3b, not shown). When the induction machine 1 is a motor it may be dynamically braked by applying D.C. or reverse phase A.C. to its stator. In Fig. 2 (not shown), the induction machine is a variable speed coupling between a prime mover 27 and a load 32. Its primary circuit is supplied with D.C. at 26 and the D.C. machine is coupled to the load through gearing. In another arrangement (Fig. 4, not shown), there are two induction motors 1, 38 driving separate loads, each with its D.C. machine and associated rectifier, the two being in parallel with each other but in series with a common controlled rectifier/ inverter 4, adjustment of which thus varies the speed of both motors while individual control is effected by the D.C. motor fields. In a further arrangement (Fig. 5, not shown), an additional rectifier 42 is incorporated to establish a voltage across a resistor 44; the polarity of this voltage is reversed when the voltage at the D.C. armature exceeds a predetermined amount and this causes a contactor 48 to close to short-circuit the D.C. armature through a resistor 47. In another arrangement (Fig. 6, not shown), there are two induction motors, wound for two phase, energized from a single-phase supply 20 with phase-splitting capacitors 59, 60; they may be traction motors in this case. The rectifiers 3 may be silicon type and the controlled converter may be mercury arc, valve, thyrister, magnetic amplifier, or rotary type.

Title: Improvements in or relating to electric alarm clocks
IPC: G04C21/20
Filed: 1945-01-24
Abstract: 597,166. Alarm clocks. WARD, H. Jan. 24, 1945, Nos. 1880, 5747 and 10059, [Class 139] An alarm control mechanism comprises a manually adjustable member which can be set to the desired time of operation of the alarm and means which can be manually pushed into an alarm stopping position said means being removed from this stopping position by the subsequent action of the clockwork. In the embodiment shown in Figs. 3 and 4, the alarm control device is applied to an electric clock. A spindle 10 mounted on two plates (not shown) is provided at the outside with a knob having a dial flange which co-operates with a fixed pointer for setting purposes. The spindle 10 carries at its other end a pin 11 which cooperates with the cammed surface of a sleeve 8 which can slide axially on the spindle 10 and which carries a wheel 7 rotated by the clockwork once in twenty-four hours. A spring 17 urges the cammed surface of the sleeve 8 into engagement with the pin 11. The alarm is operated when the pin 11 registers with the notch 9 of the cam as in this position, see Fig. 3, the spring 17 contacts a conductor collar 22 mounted on a spindle 21 and closes the circuit to the alarm device (not shown). As the wheel 7 continues to rotate under the action of the clockwork the sleeve 8 is moved axially down as the pin 11 moves from the notch 9 and so the spring 17 is moved away from the collar 22. If it is desired to stop the alarm then the spindle 21 is pushed inwardly until its notch 27 is engaged by a spring pressed finger piece 28 in which position, see Fig. 4, the collar 22 is out of engagement with the spring 17. The gear wheel 7 continues to be driven by the clockwork and the sleeve 8 is moved axially downward causing the spring 17 to engage an arm 32 which is integral with the finger piece 28. The arm 32 is thus caused to pivot and bring the finger piece 28 out of the notch 27 and so the alarm will operate at the required time in the next cycle of twenty-four hours. Provision is made for the finger piece to be held in the notch 27 permanently if desired. Figs. 6 and 7 show the invention applied to the type of clock in which a tuned reed 50 vibrates to cause the alarm signal. In this case the alarm is operated when the pin 11 carried by a shaft 10 engages the notch 9 in the cammed surface of a sleeve 8 as before. The sleeve 8 is pressed into engagement with the pin 11 by a spring 51. In the operative position, Fig. 6, the reed 50 is free to vibrate and cause the alarm to operate. Upon the continued rotation of wheel 7 the spring 51 is flexed against a spring pressed rod 52 so causing this rod to move to the right and press an extension of one arm of a double armed lever 59 against the reed 50 to prevent it from vibration. Again if it is desired to stop the alarm a spindle 21 is pushed inwardly until its notch 27 is engaged by a finger piece 54, see Fig. 7, whereupon the reed 50 will be held as shown. The push rod 21 is released in the subsequent operation of the clockwork.

Track apparatus for stopping trains. -In apparatus of the kind in which the brake valve is operated by a cam controlled by a plunger carrying a shoe for engagement with a track ramp, a closed air conduit in communication with the brake-pipe extends through the plunger, plunger head, cam shaft and valve casing so that breakage or removal of any part causes an application of the brakes. The apparatus described and shown is similar to that described in Specification 145,580. Fig. 5 shows the spring pressed plunger 41 carrying a shoe as described in Specification 219,551 and provided with a plunger head 50 in which slides a fixed hollow piston 56 in communication through a port 54 with the brake, pipe. The plunger head 50 carries a nose or projection 58 for co-operation with the hollow cam 75 on the spindle of the brake-valve shown in Fig. 9, which is bored to connect the chamber in the cam 75 with the valve cnamber 89, which is connected to the brake pipe by the union 139. The valve spindle carries a cam 127 which serves to operate valves 105, 120. The valve 105 is normally closed, and when opened vents the brake pipe to atmosphere at port 113. The valve 120 is normally open to connect the valve chamber 89 with the driver's valve through the union 133, thus allowing a manual application of the brakes. The operation of the cam 75 by the plunger is controlled by an electromagnet supplied with current through the plunger shoes from a ramp, the circuit being controlled according to the condition of the traffic on the section ahead.

Abstract: 851,054. Combustible gas. STEINMULLER G.m.b.H., L & C. Jan. 22, 1957, No. 2253/57. Class 55 (2). In a process for reducing the hydrogen content while increasing the net calorific value of hydrogen-containing coal gas formed by degasifying coal, more particularly coal dust in suspension, the gas is brought into contact with a solid oxidising agent comprising a reducible metal oxide, preferably Fe 2 O 3'  or CuO, at a temperature which is sufficient for the reduction of this oxide by hydrogen, the reduced oxide then being oxidised by ignition in the presence of oxygen and used again to reduce the hydrogen content of coal gas. Two chambers on fluidised beds may be used in a closed cycle process or alternate oxidation and reduction processes in one chamber alternate with oxidation and reduction processes in the other. Heat produced during oxidation is used in the reduction process.
