Title: Filter element and method of making same
IPC: B01D29/00
Filed: 1950-07-06
Abstract: 683,639. Filters; filtering media. HAWLEY PRODUCTS CO. July 6, 1950 [July 13, 1949], No. 16944/50. Class 46 [Also in Group V] A filter element of moulded fibrous material comprises a tubular body having an open and a closed end, an upper portion, a lower portion of smaller crosssection and a base portion. The upper portion 1, Fig. 1, is surmounted by a flange 2 and is integral with a lower portion 3 provided with flutes 7 which extend into a frusto-conical base portion 4. Four of these flutes extend also into the bottom portion 5, Fig. 3. The upper portion 1 is arranged to fit snugly inside a filter casing 11, Fig. 4, to form a seal with it, the flange 2 resting on a flange 10 of the casing 11 for ease of removal. The direction of flow is outwards, flow of the filtrate to the outlet 13 being facilitated by the flutes 7 and by the fad that the lower portion 3 of the element is spaced from the casing 11. Fig. 5 (not shown) illustrates an apparatus for preparing the element: a heavy perforated mould 16 roughly in the shape of the finished article is covered by a screen 17 having the desired shape. Suction is appliedthrough an inlet 18 of the mould 16 to cause deposition of fibres from a dispersion contained in a vessel 14 in which the body is immersed. After a sufficient layer of fibres has been deposited upon the screen the mould is removed and the moulded element transferred for drying or dried upon the mould 16. The element may be made from celluose fibres such as wood pulp, sulphite pulp, cotton linters, wheat and oat straw, bagasse and esparto, or fom wool fibres or spun glass or synthetic fibres or fom any combination of these, e.g. 50 per cent cotton linters and 50 per cent rag stock. The fibres are held together by a binding-agent which is preferably a wet-strength resin for example, a one-stage phenolic resin of the phenolformaldehyde type or a melamineformaldehyde type of resin. The resin may be applied by immersing the moulded fibrous article in it for a sufficient length of time to allow a coating to form on the fibres, but preferably by introducing the resin into the beater in which the fibres are beaten. The resin finally becomes deposited on the individual fibres which may then be moulded into the finished product without the need for an immersion step.

Title: A process for refining hydrocarbon oils
IPC: C10G17/02
Filed: 1938-06-10
Abstract: 505,141. Purifying oils and waxes. ELKINGTON, H. D. (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij) June 10, 1938, No. 17326. [Class 91] In the refining of mineral oils by treating with a strong acid, the sludge is separated in the presence of a low-molecular hydrocarbon at a temperature above the critical temperature thereof. The low-molecular hydrocarbon may be added before, during, or after the addition of acid. Examples are, methane, ethane, propane, n-or iso-pentane or -butane, propylene, ethylene, or natural gas. The oil may be pre-diluted with mutual solvent for the oil and low-molecular hydrocarbon, whereby high pressures are avoided. Examples are, ethane, propane, butanes, heptanes, gasoline, naphtha, or chlorinated hydrocarbons such as propyl chloride. Strong acids specified are, sulphuric, phosphoric or a mixture of sulphuric and acetic acids. Crude wax-containing mineral and tar oils, or distillates especially lubricating and transformer oils are treated. In an example, a residual oil is freed from asphalt by adding propane, and the resulting solution is saturated with methane at 300 1b. pressure and treated with concentrated or fuming sulphuric acid at 20‹ C. After agitation, the sludge readily settles, and the oil is freed from ethane, and propane, and finally neutralized with caustic soda, isopentane being added to avoid emulsions. Waxes may also be purified at a temperature above the melting point.

Title: Method of and apparatus for modulating electron streams
IPC: H01J31/42
Filed: 1936-06-23
Abstract: 472,861. Cathode-ray tubes. FARNSWORTH TELEVISION, Inc. June 23, 1936, No. 17420. Convention date, July 6, 1935. [Class 39 (i)] In cathode-ray tubes such as television image - dissectors, an intense, composite electron stream corresponding to an optical image is produced by means of a grid having a continuous photo-electric surface on one side and an insulating surface on the other side. The grid may be formed by uniformly coating a wire foundation 25, Fig. 2, with insulation 26 and then adding a photo-sensitized silver layer 27 on one side, or a silver foundation 29, Fig. 3, may be coated on one side with insulation 26 and photo-sensitized on the other side 30. In both cases, the insulation is applied by smoking with burning magnesium and the silver is photo-sensitized by oxidizing by a glow-discharge in oxygen and applying caesium, excess of caesium being removed as by baking the tube at 60 on the pump. The grid 4, Fig. 1, so prepared is mounted with its photo-electric surface facing a window 2 and a cathode 7 producing electrons flooding the grid. When an optical picture is projected through the window 2, corresponding charges are produced on the insulation 26 of the grid and an electron image is produced and deflected over an apertured anode 17 containing a more positive electrode 19 to produce television signals. Discharge of the charge image on the insulation 26 may be produced by leakage or the presence of gas, but preferably by secondary electron emission consequent on bombardment of the insulation by some of the faster electrons from the cathode 7. Other of these faster electrons may produce secondary emission from the photo-electric surface, some secondary electrons and the photo-electrons producing charges on the insulating surface of the grid. The grid 4 may be positive with respect to the cathode 7 and a separate accelerating anode may be used. Wall coatings 12, 14, 22 form an electrostatic lens. The electron stream flowing from the grid 4 towards the anode 17 may be focused and deflected magnetically. Specification 472,859 is referred to.

Title: Improvements in or relating to sawtooth current generators
Inventor: PLUMLEY MAURICE CHARLES
IPC: H03K4/32
Filed: 1953-06-25
Abstract: 757,593. Sawtooth generating circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. June 25, 1954 [June 25, 1953], No. 17598/53. Class 40 (6). A sawtooth current generator of the resonant return type comprises a driver valve driven by pulses produced in the output valve of a sinusoidal oscillator. The Figure shows a convetional driver valve output circuit for producing a sawtooth current in a deflection coil 5 and comprising an H.T. boost capacitor 3 and a damping diode 6. The drive for the output valve is obtained from a sinusoidal oscillator valve 7 biased by a grid leak circuit such that anode current flows only during the peaks of the grid voltage waveform. The resulting current pulses through the valve 7 are made more rectangular by feeding back of voltage through a capacitor 16, the grid current limiting the peaks of the grid voltage and the resistor 11 being of such magnitude that the voltage fed back does not distort the sinusoidal voltage in the tuned circuit 8, 9. The feedback voltage may alternatively be obtained from a winding on transformer 2 or from an undecoupled resistor in the screen grid of a screened grid output valve. The point during the forward stroke at which the driver valve becomes conductive is adjusted by adjusting the width of the pulse on its grid and this is done by adjusting the value of the grid leak and thus the bias of valve 7.
