Title: Improvements relating to receivers of radar signals
IPC: G01S7/34
Filed: 1965-04-02
Abstract: 1,094,422. Monitoring radar signals; aerials; radio receivers. MAXSON ELECTRONICS CORPORATION. April 2, 1965 [April 13, 1964], No. 14097/65. Headings H3Q, H4A, H4D and H4L. [Also in Division G4] A hand-portable radio receiving device comprises in one housing aerials 26, 28, Fig. 2, detectors 14, 16 fed from respective aerials, a video amplifier 40, Fig. 3, having a gain which decreases as input signal amplitude increases followed by a pulse lengthening circuit 42, and a battery. The device is particularly utilized for detecting on a craft the presence of signals from a distant radar transmitter e.g. on a pursuing craft, the receiver output being fed to an external meter and/or head-phones. By inserting a fixed amount of attenuation before the video amplifier and noting how far the craft moves towards the transmitter to give the same output as before attenuation coarse range is estimated. The amplifier (see Division G4), Fig. 3, comprises alternate PNP, NPN transistor stages in cascade to afford an overall gain approximately varying as 1/log (input level). The aerials are directional thereby providing manual direction-finding. Aerials.-Each aerial, Fig. 2, is an openended rectangular waveguide; the waveguides have parallel longitudinal axes, their open ends are in the same plane but orthogonal to one another to permit a signal output for waves of any polarization, the waveguides incorporate posts 36 for matching to free space, and a plastic window is glued over the open ends. A frequency range of 1G c/s. to 70 G c/s. is mentioned. To reduce aerial aperture on low frequencies ridged waveguides are used, Fig. 5 (not shown).

Title: Improved process for the production of cellulosic plastic board or like material
IPC: D21J1/00
Filed: 1941-11-05
Abstract: 555,285. Cellulose ester fibrous sheets, boards &c. COTOPA, Ltd., and CHIPPINDALE, E. Nov. 5, 1941, No. 14261. [Class 2 (ii)] [Also in Group VIII] Fibrous plastic sheet, board, or like material is obtained by saturating a fibrous partially esterified cellulose material with an acetylating mixture containing a liquid which prevents solution of the cellulose ester, allowing the reaction to proceed so as to acetylate the material to a higher degree of esterification, and subjecting the material to pressure so as to bond the swollen fibres and form the desired sheet material. Cotton waste which has been acetylated to produce a fibrous material containing 20-30 per cent. of combined acetic acid may be hydrated, i.e. pulped with water to a degree suitable for forming a paper. The paperlike partially acetylated material may be built up in layers to the desired thickness and placed in a press, each thickness being separated e.g. by a perforated metal sheet resistant to acetylation liquids. The press may be made of zincfree bronze. It may be placed in a closed vat into which is run an acetylation mixture comprising acetic anhydride, acetic acid, zinc chloride, and benzol or ethyl acetate. The fibres are swollen but kept intact and they are further acetylated up to 55-60 per cent. combined acetic acid. They are then bonded into a board by the pressure of a hydraulic ram. The board may be washed by means of an inert solvent such as benzol. The compressed material still in the frame is transferred to an oven in which hot air is freely circulated. It may be completely dried in this oven, or it may be washed with water and then dried. Specifications 280,493, 323,500, 323,515, 323,548, 324,680, [all in Class 2 (ii)], 372,312, 395,737, [Group VIII], and 489,928, are referred to.

Title: Improvements relating to hand operated grease guns
IPC: F16N3/12
Filed: 1927-05-27
Abstract: 275,134. Kreidel, H. May 27, 1927. Single - acting suctionvalveless piston pumps; suction and delivery reservoirs. - A hand-actuated grease gun comprises a working cylinder h with a grease receiving chamber h<1> at its upper end and a delivery nozzle i which when pressed against an oil hole forces a plunger e down into the grease chamber h<1> of a cylinder h thereby forcing the grease through a non- release valve k and through the nozzle i, the cylinder h being packed by a ring n at its lower end and its upper chamber h<1> being packed by an annular packing ring o. When the gun is withdrawn from the oil hole a spring l withdraws the cylinder head h<1> from the plunger e and causes a vacuum which is filled up by grease entering from the main container a through ports f. The vacuum also causes the piston b to move down in the container a, the packing disc b<2> being sufficiently tight to maintain the vacuum until this movement takes place. The chamber h<1> of the working cylinder is spun over at the end to grip the elastic packing ring o and its retaining ring p. The piston b can be easily withdrawn from the main grease container by a chain and spring bolt which arches the packing disc b thus relieving its edges from pressing against the sides of the container.

Title: Improvements in or relating to the treatment of meat
IPC: A23L13/70
Filed: 1941-11-07
Abstract: 557,007. Preserving food. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Nov. 7, 1941, No. 14361. Convention date, Nov. 13, 1940. [Class 49] Food is sterilized and the growth of bacteria, mould, &c. thereon is inhibited by maintaining a low proportion of ozone in the surrounding air. The concentration employed is from 0.1 to 1.0 parts per million, and the period of treatment is from twenty to forty hours. The food when in the form of meat is rendered tender by temporarily keeping it at a temperature of about 60‹F in an atmosphere having a humidity of about 90 per cent, the ozone being introduced during this process. Apparatus for carrying out the above treatment comprises a chamber 11 in which the food 15 is suspended from rails 12. The air therein is circulated by a fan 19 which forces it through openings in a duct 23 and draws it back into a compartment 16 through a glass wool or other filter 21 impregnated with manganese dioxide to reduce the remaining ozone to oxygen and so prevent excessive accumulation of ozone. The air passes over a water reservoir 24 and through a water spray 22, in which is a cooling coil 28, and past a steam-heated coil 57 before passing through the fan 19. A temperature bulb 31 actuates an instrument 18 whereby a three-way mixing valve 32 is operated, e.g. by compressed air led by lines 33, 34 to a diaphragm 35, to determine the temperature of the coil 28. A temperature bulb 41 actuates an instrument 17 which both determines the temperature of coil 57 through a diaphragm 54, and the position of a damper 44 through a diaphragm 45. The ozone generator 59, which may be of the silent electric discharge type or a low pressure mercury discharge lamp having a quartz envelope enclosing electrodes 61, 62, is located either in a duct 65 or directly in the duct 23. Specification 510,813 is referred to.

Title: Television image projector
IPC: H04N5/74
Filed: 1950-06-09
Abstract: 684,706. Cathode-ray tubes. SOC. GENERALE d'ELECTRONIQUE. June 9, 1950 [June 9, 1949], No. 14471/50. Class 39(i) [Also in Group XL(b)] . A cathode-ray device for projecting optical images. comprises a screen P, Figs. 1, 2, scanned by the beam and formed as - a metal support 1 coated with insulation 2, and on the insulation 2 are secured, at one edge thereof, a network of small metal elements 3 having a thickness of 100-3000 Angstroms e.g. 1000 Angstroms and the major portions of which are spaced from the insulation 2 by the order of a few microns e.g. 1.5 microns, the elements 3 constituting a plane mirror when at rest. The scanning beam impinges on elements 3 and passes through them generating a larger number of secondaries which emerge from the opposite sides and go to the layer 2; provided the original beam emerges from the elements 3 with a velocity of less than 200 volts the secondary emission ratio of the layer 2 is less than unity. Thus the elements 3 are charged positively and the support 2 negatively in dependence upon the beam modulation and the resultant electrostatic attraction between them'causes elements 3 to deflect proportionally. The light generated by slot source S and reflected by mirror M on to screen P is normally reflected by P and focussed on to the edge of slot S<SP>1</SP> so that no light passes through diaphragm D; however when an element 3 is deflected the direction of light it reflects is slightly altered so it can pass through slot S<SP>1</SP> and form an image point on a screen behind it. All the dimensions of elements 3 are smaller than the width of a line and the rows of elements are greater in number than the number of lines; the elements may be square and the rows preferably make an angle of 45‹ with respect to the scanning lines. The insulating layer 2 has such a resistivity and thickness as to discharge the target before the next scan. The light emerges from the cathode-ray tube through an optically plane polished window G. The members 1, 2, 3 may be of nickel, magnesia and aluminium respectively. The gun anode potential is variable to obtain maximum efficiency. The desired amount of contrast can be obtained in the final image by a selective variation of the brilliancy of the various points of the source S or by varying the shape of slot D. Dimensions of a particular example are given. The metal base and insulation may be transparent and light projected on to and reflected from the opposite side of the metal elements to that scanned by the electron beam.

Title: Process for the complete, or almost complete, extraction of the sugar from molasses
IPC: C13B35/04
Filed: 1926-06-11
Abstract: 266,187. Steffen, (nÚe Jelinek), L. May 20, 1926, [Convention date]. Purifying saccharine liquids; refining sugar.- Relates to a process for extracting sugar from molasses by precipitation, as tricalcium saccharate, from diluted molasses by means of lime until the liquor still contains about 0.5 per cent of sugar, the saccharate being separated by filter pressing and worked up to sugar, and the sugar remaining in the liquor being precipitated completely by adding an excess of lime. According to the invention, the saccharate obtained in the second precipitation is separated by filter pressing, mashed with fresh dilute molasses solution. and the soluble sugar-lime compound produced precipitated as insoluble saccharate by lime. The molasses is first diluted with water in container b and forced by pump c into precipitation apparatus comprising a cooler v, a container r in which powdered lime is added, and a precipitation chamber d. The saccharate produced is separated in filter press f, and the liquor passed to container g from which it is forced by pump h into a similar precipitation apparatus where the sugar remaining in solution is precipitated by excess of lime. The tricalcium saccharate produced is separated in filter press k, the liquor passing to waste, and is next mashed in receptacles l with fresh dilute molasses and passed to container b where it is mixed with a further amount of diluted molasses, the mixture being passed to the pre. cipitation apparatus d, v, r. The amount of lime now required for precipitation is less than formerly owing to the higher activity of the lime liberated on mashing the saccharate with the molasses.
