Title: Treatment of tar used as sealing medium for the pistons of waterless type gas holders
IPC: F17B1/06
Filed: 1933-03-28
Abstract: 407,534. Tar. TOOBY, C. F., 1103, Foleshill Road, and LANGFORD, P. N., 970, Foleshill Road, Coventry. March 28, 1933, No. 9264. [Class 55 (ii).] To maintain the viscosity of tar escaping from the seal of a waterless gas holder, it is heated prior to its return to the seal in contact with a stream of gas. The tar is conveyed by a pipe e to a tank c where it is heated by steam coils l and treated by bubbling gas just below the tar surface through the perforated head o of a pipe m ; or the gas may be passed over the surface of the tar. The gas is then returned to the gas holder and the tar passed through a tank f to a tank g containing a float h operating a spindle j to put in action pumps which raise the tar through a pipe k to the top of the gas holder. The gas may be preheated by passage through a steam jacket n and the tar may be preheated by steam coils arranged in the tar dam at the base of the holder.

Title: Improvements relating to electrically actuated detection or warning systems
IPC: G08B17/103
Filed: 1947-04-08
Abstract: 636,341. Valve relay circuits. TRIST & CO., Ltd., R., and CHAMBERS, W. A. April 8, 1947, No. 9333. [Class 40 (vi)] [Also in Group XL (b)] In a detection or warning system, a change in the voltage across a photo-electric cell is used to bias the control electrode negatively with respect to the cathode of a cold cathode valve and so to initiate the discharge through the valve. In a smoke detection and warning system, two photo-electric cells 4, 5, normally illuminated with the same intensity, are connected in series across a battery 11. The cold cathode of a valve 14 is connected to the mid-point of the battery and the control electrode of the valve is connected to the junction of the cells 4 and 5. The light beam falling on photo-electric cell 5 is protected from smoke which reduces the amount of light falling on the cell 4, and causes a small negative potential relative to the cathode to be applied to the control grid of valve 14, initiating a discharge through the valve and energizing a relay winding 18. Relay contact 26 connects a visible warning signal 22 and an audible alarm 21 to a potential source 27. Relay contacts 19, 20 break the anode circuit of the valve, and connect the relay winding across the supply 27 so that the alarm signals continue till pushbutton 23 is pressed to reset the circuit.

Class 75 (1) A liquid fuel burner in which fuel fed through a, conduit 14 on to a deflector plate 27 is directed radially outwards on to a rotary diffuser 22 to be atomized at the exit end thereof by an annular stream of atomizing fluid and in which the diffuser 22 is driven by a vane 26 arranged in the atomizing fluid passage prior to the diffuser 22 has the vane 26 arranged in a chamber 1 through which the atomizing fluid passes and which is connected to one or more passages 30, 31 which direct the atomizing, fluid on to the fuel emerging from the diffuser 22. The amount of atomizing fluid passing through the chamber 1 can be varied by adjusting a threaded sleeve 4 so as to allow more or less fluid to pass to atmosphere through orifices 6, 7. A tube 18 rotatably mounted on the conduit 14 on bearings 19, 20 is formed at its forward end into the conically shaped diffuser 22 and has the vane 26 mounted on its outside within the chamber 1. The atomizing fluid enters the chamber 1 in the direction of arrows A and exerts a thrust on the tube 18 in the direction of arrow B so as to urge the small end of the diffuser 22 into an opening 29, to prevent leakage of the atomizing fluid from the chamber 1, and to press a sealing ring 24 against a stuffing member 25. Some of the atomizing fluid may be led from the chamber 1 into the conduit 14 through a pipe 32 provided with a valve 33. If heavy fuel such as mazout is used super-heated steam may be used to drive the vane 26 and to pre-heat the fuel in conduit 14 and an independent supply of air may be fed to chambers 8, 9 leading to the passages 30,31. Blades may be provided in the channels 30, 31 to impart a rotational movement to the fluid passing therethrough.

Abstract: 1, 015, 169. Fluid-pressure servomotor systems. M. DELBERGUE. March 9, 1964 [March 13, 1963], No. 9912/64. Heading G3P. A number of storage tanks 1, 2, 3, Fig. 1, such as vats are emptied in uninterrupted succession by a device comprising a three-way drain valve 7 actuated by a jack 8, a collector tank 11 containing a float 14 actuating a relay valve 16, a connection 17 between the relay valve and a fluid supply conduit 18 for the jack, and a control conduit 19 to convey a pulse of fluid to a reversing valve 28, Fig. 2, for the jack when the level in the collector tank corresponds to the completion of the emptying of a vat. When the tank 1 is empty the liquid level falls in the tank 11 and the float 14 actuates the relay valve 16 to cause a pulse in the conduit 19 to reverse the valve 28 and hence the jack 8 so that the valve 7 now permits the vat to be discharged. The pulse also sounds a whistle 25 to warn the operator to transfer a flexible pipe 5 from vat 1 to vat 3 and to reverse a manual selector valve 26 in readiness for the next control pulse. An air relief valve 22 is also opened by the pulse which passes first through a delay gate 24. A pulse may also be generated by a manually-actuated valve 20. A lubricator 30 is fitted to the fluid supply line 18. Fig. 3 shows a modified arrangement in which the pulse in control conduit 19 opens a valve 32 to supply a whistle 34 through a manually actuated valve 35 the whistle remaining energized through a valve 36 after the valve 32 has closed and to open a valve 38 and close a valve 29. The valve 38 in turn causes actuation of a pair of reversing valves 44.45 and opens a valve 42 to by-pass the valve 38 after the pulse has allowed the latter to close. Termination of the pulse also allows the valve 39 to re-open and actuate a valve 37 to direct the following pulse to a valve 41 instead of the valve 38 so that the valves 44, 45 will be connected to atmosphere and reverse the supply to the jack. In a further modification, the valve 37 is manually actuated.

Convention date, April 5, 1930. [Class 143.] The weight recording, indicating, integrating or printing mechanism of a weighing- machine is actuated by electrical impulses, means being provided to produce a set of electrical impulses for each digit of the weight when the weighing mechanism has attained its equilibrium position and the number of impulses in a set being equal to the number denoted by the corresponding digit. A drum 2 is rotated through an angle proportional to the load and registers with a fixed annular chart to indicate the load. The cylindrical surface of the drum is provided with a number of contact strips 9 divided axially into zones corresponding to the different denominations of the weight. Brushes mounted on a slide 4 are moved transversely across the surface of the drum, each brush contacting with the strips of a zone. The resultant impulses operate through apparatus of known type to set or actuate indicating, integrating or printing mechanism. In a modification the chart is transparent with opaque lines or opaque with transparent lines, and the impulses are produced by light-sensitive cells moved transversely of the chart. When the invention is applied to a machine of the sliding-weight type, the drum may be replaced by a strip of film having opaque and transparent areas and unrolled by a spindle connected to the sliding weight. The drum is clamped during the reading operation, a dashpot or other device serving to effect a time lag between the unclamping and clamping of the drum.
