Title: Improvements in and connected with screw pile driving
IPC: E02D5/38
Filed: 1927-03-17
Abstract: 281,148. Braithwaite & Co., Engineers, Ltd., and Freeman, R. March 17, 1927. Piles; piles, driving.- Apparatus for driving screw piles including a rotatable screw head is provided with a thin walled metal cylinder connected to the screw head so that it follows the latter into the ground and constitutes a mould for a concrete or like pile. The screw head a, Fig. 1, is rotated by means of a solid shaft b, or by means of a hollow tube c, Fig. 3, the lower end of the shaft or tube being provided with flats which enter a correspondingly shaped socket d in the screw head. The neck f of the latter is formed with a circumferential groove h within which engages an inturned flange i on the thin walled metal shell or tube g. Sections of any length may be added to the tube g as sinking proceeds. Rollers may be supported around the driving shaft or tube at intervals to locate the latter axially in the tube g, and, if necessary, to support it against external pressure. Alternatively, the driving shaft may be made with an external diameter slightly less than the internal; diameter of the tube g. Flanges k, Fig. 3, provided for bolting together the sections of the driving tube c may also serve to support the tube g. When sunk to the required depth, the driving shaft or tube is withdrawn, and the tube g filled with concrete, cement aggregate or other filling. A hollow pile may be produced by using a temporary or permanent inner shell.

Title: A process for the melting of metals, for example copper, and an electric furnace forthe performance of said process
IPC: C22B5/06

Abstract: 982,135. Metal melting furnaces. I. PROPERZI. Feb. 26, 1962 [March 4, 1961], No. 7450/62. Heading F4B. [Also in Division H5] Metal 3, e.g. copper, to be melted in a furnace is completely covered by a layer 9 of graphite or carbon powder through which the heating current passes, the layer 9 thus acting as a heating resistance and as a protective layer which also maintains a reducing atmosphere in contact with the charge. In the three-phase furnace shown three electrodes 5 are each supported in a well in an upper part 4 of the furnace provided with rollers which run on rails 17 supported by brackets 23 from a lower part 16 of the furnace enclosing an elongated melting basin 1 which is provided with a pouring spout (not shown) and may contain a floor 2 of carbon or silicon carbide. An hydraulic piston 19 enables the furnace to be tilted about pivots 20 on an axis A-A near the pouring spout. The current bars 6 of each electrode 5 are secured to a bar 11 supported from the furnace part 4 by insulated screws 12 and 13 permitting vertical adjustment of the electrode. Each bar 11 is connected by leads 14 to a transformer bar 15. Each electrode 5 has a tapering end 7 to reduce the loss of heat through the electrode. Alternative forms of electrode are described (Figs. 6-9, not shown). When charging and discharging the furnace, the upper part 4 is moved to the right, loss of powder 4 from the upper portion being prevented by a portion 18 of the lower part 16. In a modified construction (Fig. 5, not shown) the lower part 16 is duplicated, so that two melting basins 1 are served by one electrode system, which may include any number of electrodes depending on the number of phases of the supply.

Title: Improvements relating to electric water heaters
IPC: F24H1/20
Filed: 1947-03-19
Abstract: 628,193. Electric water heaters. G.M. ENGINEERING (ACTON), Ltd., FLETCHER, F. L., STOWE, G., and SMITH, P: A. March 19, 1947, No. 7614. [Class 39(iii)] A water heater comprises a storage container 5 having at least one separate shroud tube 13 into which condensed water is directed by a condensing device above the water level, a hood 22 having a depending skirt 21 being supported in the storage container 5 so as to cover the upper open end of the shroud tube 13 whereby air pressure in the hood prevents water entering the shroud tube 13 by the top. An inlet pipe 14, outlet pipe 15, electric heating element 16, and a thermostat 20 are carried by a plate 17, and pass through a plate 8 which supports the container 5. The cold water is delivered to a space formed between the hood 22 and a hood 24 secured to it, so that the lower surface of the conical depending hood 22 serves as a condensing surface for distilled water in the tube 13. The cold water flows down a pipe 23 and enters the container 5 through holes 25. Water pressure in the container 5 opens a valve 40 to allow the tube 13 to be filled initially. When the tube 13 is full and valve 40 is closed, no water can enter it, an air lock being formed under the hood 22. A bent pipe 29 is provided in container 5. In one alternative construction the valve 40 is dispensed with and a vent pipe passes through the hoods 22 and 24 and depends in the tube 13, which is then initially filled from the top until the water level therein covers the lower end of the vent, and an airlock is established. In two further modifications, the tube 13 is filled from the top through a hole in its wall, which hole has a valve operated by a bimetallic member or by a float in the tube 13.

In electronic apparatus for plotting instantaneous point values of a recurrent electrical waveform against the timebase of a display device (Fig. I) pulses from a master pulse generator trigger a waveform generator producing the waveforms to be examined, which are applied to the Y deflection plates or coils of a cathode ray tube through a gate circuit which is recurrently opened for a short time interval to make a plot by pulses from a pulse generator triggered by the output of the master generator through a variable delay circuit, thus determining the point on the waveform whose value is to be displayed. The master generator output also triggers a sweep circuit whose recurrent output waveform is applied to the X deflection plates or coils through a time delay circuit controlled by the gating pulses so that at the instant of making a plot the instantaneous values of the sweep voltage and of the waveform to be examined are respectively applied to the X and Y deflection plates or coils of the C. R. tube. In a modification (Fig. 2) the master pulse generator pulses a trigger circuit to initiate the operation of the sweep generator and of the gating pulse generator, while the gating pulse generator operates a sweep termination circuit through a fixed time delay circuit to impress the instantaneous value of the sweep voltage on a peak amplitude measurement circuit (which may include a storage circuit) developing a deflection voltage applied to the X coils or plates of the C. R. tube. Details of the sweep generating and terminating circuits appear in Fig. 3 (not shown).

Abstract: 1,149,832. Electro-chemical analysis. STANDARD OIL CO. Feb.21, 1967 [Feb.21, 1966], No.8087/67. Heading GIN. The nitrogen content of a nitrogen-containing material is determined by a process comprising catalytically converting the nitrogen to ammonia and automatically titrating the ammonia electrochemically. The nitrogen-containing material may be converted to ammonia over a heated nickel/magnesia catalyst in the presence of humidified hydrogen in tube 2. The ammonia is introduced into the titration zone of cell 4 and is detected by sensing electrode pair 12, 14, causing imbalance between the potential difference between these electrodes and a reference potential. The imbalance is applied as a signal causing the generation of hydrogen ions by electrodes 8, 10. The amount of electricity required to produce enough hydrogen ions to restore the balance is a measure of the amount of nitrogen in the material under test.
