Title: A method and apparatus for forming columns of material in soil
IPC: E02D3/10
Filed: 1963-12-17
Abstract: 1,074,688. Boring earth etc.; piles. R. E. LANDAU. Dec. 17, 1963 [Dec. 21, 1962; July 5, 1963 (2); Nov. 21, 1963], No. 49805/63. Headings E1F and E1H. Apparatus for forming columns of material in the ground comprises an auger 10 having a flight 12 and carrying a hopper 16 at its upper end. The auger and' hopper are rotated by a shaft 26 driven by motor 30 and reduction gearing 28. The motor and gearing are mounted on a carriage 32 slidable on uprights 44, 46, the weight of the motor, gearing, carriage, hopper and auger providing the force driving the auger into' the ground. During normal boring the lower end of the auger is closed by a cap (58, Figs. 4, 7) which may be replaced by a drill head to penetrate obstructions or bedrock, or by a bit (292) to sample the ground, or by a probe to test the earth. The auger is prevented from falling rapidly through voids or soft ground during drilling by a pivoted spring urged member (254, Fig. 4) fixed to the uprights and engaging the underside of the flight. The hopper is loaded with coarse sand M for forming a sand drain by a bucket 176 pivotally mounted on a carriage and having a slide 192 which opens on contact with the coaming 132 of a pivoted, pneumatically controlled door giving access to the hopper. As the auger which is not rotating is withdrawn from the hole sand is fed into the hole, the falling of the sand being ensured by air supplied from nozzles 108, 116 and by a vibrator 166. Apparatus (Fig. 6 not shown) suitable for forming a concrete pile, has extending within the auger a shaft (270) carrying a flight (286). The shaft (270) is driven in either direction by gearing (278), or permitted to rotate with the hopper by the disengagement of a clutch (29), and may be fed vertically by a feed-nut (272). The flight (286) serves to eliminate segregation of the aggregate of pre-mixed concrete, and to feed the concrete into the cavity formed by the auger. A vibrator may be inserted into the freshly deposited concrete through the shaft (270) apparatus may be lowered through the shaft to sample and bearing test the ground, a weight may be added to the shaft (270) during drilling through obstructions or when depositing the concrete, and a drill may be fixed to the shaft (270) to drill bedrock to form a seat for the pile. A pile having a smaller diameter upper portion may be formed by reverse rotation of the auger as it is withdrawn from the upper portion.

Abstract: 1375200 Selective signalling SCHLUMBERGER INSTRUMENTS ET SYSTEMES 28 Oct 1971 [28 Oct 1970] 50070/71 Addition to 1314264 Heading G4H In a data transmission system, a central unit is connected to a plurality of stations by a single two-way (one-way-at-a-time) transmission link common to all the stations and an select a station by sending a mixture of p+1 frequencies uniquely characteristic of the station, then select a data point from several within the selected station by sending a mixture of p frequencies uniquely characteristic, within the station, of the data point, the selected data point transmitting data, the central unit comprising switching means for switching the central unit into a receiving mode for a preset time after the transmission of at least one mixture of frequencies, and each station comprising switching means for switching the station into a transmitting mode for a preset time after the detection of said at least one mixture of frequencies. When a station receives a combination of 4 out of 6 frequencies which identifies the station, an inhibit multivibrator is set and a monostable is triggered (both in response to the trailing edge). The monostable gates a combination of frequencies (from oscillators at the station) specifying the number of data points at the station, to an output line, the presence of the signal being detected to connect the output line to the transmission path for as long as it lasts (the duration of the monostable). The station next receives a combination of 3 of the possible frequencies which identifies a data point at the station, the concurrent set state of the inhibit multivibrator permitting these to trigger (at their trailing edge) a monostable which gates each of a combination of frequencies to the output line or not according to the value of respective data values at the data point. The presence of the signal on the output line is detected to connect the output line to the transmission path for as long as it lasts (the duration of the monostable). The inhibit multivibrator is reset by inhibition frequency sent from the central unit after all the data points have been called. The data-point identifying frequencies can perform a control function (via a duration discriminator) by making them of longer duration. The transmission path is a two-wire telephone line, or a radio link. The main switch at the cantral unit (see above) is controlled by a time base circuit which also controls the transmission of signals to the stations. Various further details are as in the parent Specification, and the use of movable connecting strips permits the system to be readily converted to use with a four-wire transmission path as in the parent.

Abstract: 1,253,652. Electron beam apparatus. NATIONAL RESEARCH DEVELOPMENT CORP. 4 Nov., 1968 [3 Nov., 1967], No. 50148/67. Heading H1D. A magnetic lens for focusing a beam of charged particles 12 on to a target 16 comprising an electrically conducting circular wire coil 13 is positioned around the beam axis behind the target 16 with respect to the beam by a distance W, from the target position axially to a plane containing the inner diameter of the nearest face of the coil to the source 11, which is less than the mean between the inner and outer diameters (= R 1  + R 2 ) of the coil. Preferably the difference between the inner and outer radii (R 2 -R 1 ) is at least twice the axial thickness T of the coil and R 2  is at least twice and preferably three times R 1 . Also R 2  is preferably not less than 5T. The coil may have a layer 20 of material of high magnetic permeability applied to the side remote from source 11 with, as shown in Fig. 4, a removable central insert 21. The high permeability layer may extend around the edges and front face of the coil, and cooling ducts for the coil may be incorporated in these layers, Fig. 3 (not shown). Alternatively, as shown in Fig. 4, the coil may be formed as a series of alternately axially offset concentric sections 30 with the passages therebetween being used as duets for a cooling fluid, e.g. transformer oil. The coil may be concave towards the source 11, Fig. 2 (not shown). Electrical connection to the inner radius of the coil may be made by using a number of symmetrically distributed connections (23) to a copper foil screen (22) interposed between layer 20 and the coil, Fig. 5 (not shown). As it is employed behind the target the lens may conveniently be housed outside the vacuum envelope, thus facilitating easier cooling in cryogenic apparatus enabling the lens to be operated in a superconducting state. The lens may be used in an electron beam cutting or welding apparatus, in transmission or scanning electron microscopes and in electron probe X- ray microanalysis apparatus.

Title: Improvements in or relating to Electrolytic Hygrometers
IPC: G01N27/12
Filed: 1966-11-15
Abstract: 1,187,389. Electrolytic hygrometers. CENTRAL ELECTRICITY GENERATING BOARD, F. BENNETT AND I.J. CONIBEAR. Feb. 9, 1968 [Nov. 15, 1966], No. 51088/68. Heading G1N. In an electrolytic hygrometer in which the moisture from a gas is absorbed by the electrolyte of a cell to change its resistance, the electrodes are made of platinum or of a metal in the platinum group and the electrolyte of partially hydrated phosphorous anhydride with a trace of cadmium. The cell is energized by a low frequency, i.e. less than 15c/s, voltage and the trace of cadmium is provided to prevent the formation of platinum black on the electrodes. During operation the cadmium is cathodically deposited on the electrodes so that during their function as anode they are provided with a protective layer of cadmium. Cell construction:- The cell is formed of two spirally wound platinum electrodes encased in a narrow bore plastics tube which is tightly coiled, potted and encased in stainless steel. Cell cleaning:- To remove any platinum black which may have formed on the electrodes, aqua regia is occasionally introduced into the cell, after removal of the electrolyte. While in this state the electrodes may be electro-polished to remove unevennesses on their surface by applying a low frequency voltage across the electrodes. Cell regeneration:- The cell is recharged with fresh electrolyte in the form of orthophosphoric acid with the trace of cadmium. The acid is partially dehydrated by passing dry air through the cell and then by the brief application of a low frequency voltage across the electrodes. Operation:- An energization circuit for one cell (INT) in operation and four cells (EXT 1-4) under rejuvenation comprises a voltage source stabilized by neon stabilizer (OA3), which is connected to the cells through relay controlled switches (RLA2), (RLA3), (RLB1-3) of relays (RLA), (RLB). Relay (RLA) is controlled by the output of multi-vibrator (12AU7) to be alternatively energized and de-energized at a frequency of 1c/s. Relay (RLB) is controlled by relay (RLA) so that the cells are energized by D.C. with alternating polarity. Switch (SW1) serves to apply the voltage either to the cell in operation or to the cells under rejuvenation and switch (SW2) completes the energization circuits to the cells through a meter (A) whereby their operation or rejuvenation may be monitored.

Abstract: 1,070,030. Data storage on deformable plastic material. RANK XEROX Ltd. Dec. 16, 1964 [Jan. 2, 1964], No. 51247/64. Heading G4C. Digital data is stored by modulating the intensity of the light spot of a flying spot scanner 40 according to the data to be stored, forming an image of the light spot on to a prechanged photo-conductive sheet 41 over coated with a film of a deformable plastic material, whereby a latent electrostatic image of the light spot is produced and heating the plate 41 (as by heat gas blower 50), whereby the plastic overcoat becomes deformed in those areas which are charged. The deformation may be erased so that the plate 41 may be used again by heating to a higher temperature. Data is read out using the same light source 40 tracked at constant intensity, areas of the plate 41 which are deformed causing (frost) scattering of the incident light which is collected by a lens system 46 and detected by a photo-multiplier tube 42. A mask 48 prevents direct light reaching the tube 42. The photo-conductive sheet which is on a transparent conducting base (e.g. of stannic oxide) may be charged by corona discharge from a fine wire grid (61, Fig. 3, not shown) in an atmosphere of nitrogen. The data track format, as illustrated in Figs. 4-6 (not shown), is circular and includes clock marks corresponding to two different frequencies on either side thereof whereby, using tuned filters and a difference amplifier, the light spot is accurately made to follow the track path. The recording area is divided into a number of concentric zones, the recording density varying from zone to zone but constant within each zone. Each track includes a datum area of 25 (8-bit) characters, the last five of which specify the starting address of the track. Alternative optical arrangements are illustrated in Figs. 7-9 (not shown), all of them using light reflected from the plate 41 instead of transmitted light.
