Title: Improvements in, and relating to, resistor elements for use in electric resistance furnaces
IPC: H05B3/16
Filed: 1932-02-24
Abstract: 400,605. Resistance furnaces. BIRMINGHAM ELECTRIC FURNACES, Ltd., Tyburn Road, Erdington, Birmingham.- (Electric Furnace Co. ; Salem, Ohio, U.S.A.) Feb. 24, 1932, No. 5474. [Class 39 (iii).] A resistor unit for an electric furnace is formed with parallel lengths a joined by semicircular ends b having integral supporting lugs c. The grid is of V-section and may be made by casting, forging, or shaping from rolled section metal, the suspension lugs c in this case being welded or otherwise connected to the body after the length of rolled section has been shaped to zig-zag form. Alternatively the grid may be made up of a series of sections, each comprising one or more sinuosities, welded together at their ends. The furnace chamber is formed with shelves or ledges d on which the supporting lugs b rest. A floor or hearth resistor, as shown in Fig. 2, has the lugs c arranged so that the apex of the V-section is uppermost, in order to radiate heat upwards and shed scale &c. falling from the work under treatment. A roof resistor is formed, as shown in Fig. 5, so as to radiate heat downwardly, the lugs c projecting from the bottom of the V-section. In the case of resistors for mounting vertically on the side or end walls, the lugs may be at right-angles to the plane of the grid. The ledges d may communicate with openings formed in the furnace walls provided with removable closures f, Fig. 8, to facilitate the insertion and withdrawal of the resistors. Conductors g<1> are welded to opposite extremities of the grid, and pass through holes in the closure f.

Title: A method of and apparatus for determining and indicating electrically the presence, position or properties of bodies
IPC: G01S11/02
Filed: 1925-02-28
Abstract: Relates to methods and apparatus of the kind described in Specification 228,167, [Class 37, Electricity, Measuring &c.], in which the proximity of the ground to an aircraft is indicated by providing on the aircraft an oscillating circuit comprising open capacity areas; and consists in modifications of such apparatus. The presence or movement of the body to be detected varies the capacity, and therefore the natural frequency, of the oscillating circuit, and this variation is detected by the heterodyne or beat method as in the prior Specification; or a relay or measuring or recording apparatus may be controlled.  The Specification as open to inspection under Sect. 91 (3) (a) states that the observed body may affect the inductance of the p  oscillating circuit and that the apparatus may be used for qualitative and quantitative determinations in chemistry. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the preparation of rod-shaped bodies of crystalline material
IPC: C04B33/32
Filed: 1955-02-24
Abstract: <PICT:0779957/III/1> A rod of crystalline material, e.g. high-purity germanium, silicon, or a compound of elements of groups 3 and 5 or 2 and 6 of the periodic table, is grown from a rod-like stub 2 of material suspended from a holder 19 which is moved upwardly and axially of the stub while additional amounts of material are fed periodically to a molten drop 11 formed by a heating coil 20 on the bottom of the stub.  The process is carried out in a vacuum or inert atmosphere inside a quartz tube 4, seals being provided for the shaft 21 for displacing the holder 19 and for shaft 52 carrying a concave-ended plunger 51 by which material from hemispherical container 50 is periodically lifted to the drop 11. In a modification the plunger 51 is dispensed with, the holder 19 being periodically displaceable downwards rapidly until the drop 11 dips into the supply of material situated below it whereafter it is raised rapidly into its previous position.  The material may be pulverous form or may be crystallites in needle form produced in a preceding purifying process, the speed at which the holder 19 is drawn upwards being preferably about 0.5 to 5 mm. per minute.

Title: Improvements in polymers of hexadienes
IPC: C08F36/04
Filed: 1943-04-08
Abstract: The mixture of 2-methyl- and 4-methyl-pentadiene-1,3, produced by dehydration of 2-methyl-pentanediol-2,4 which is itself made by hydrogenation of diacetone alcohol, is polymerized alone or copolymerized with such polymerizable compounds as butadiene, acrylonitrile, styrene and methyl methacrylate.  It is also incorporated as a modifier in the copolymerization of butadiene with other polymerizable compounds.  In examples: (1) the mixed methyl pentadienes are heated with sodium and oleic acid in a steel tube at 45-100 DEG  C. for several days to yield a rubber-like polymer. Solvent or emulsion polymerization may also be used; (2)-(6) mixtures in varying proportions of the methyl pentadienes and butadiene, acrylonitrile, styrene or methyl methacrylate are emulsified in a solution of the sodium salt of higher fatty alcohol sulphuric esters, buffered to, say, 6.5-8, an oxidizing catalyst such as sodium perborate, and promoters or modifiers such as carbon tetrachloride, acetaldehyde, and potassium cyanide added, and the mixtures polymerized, usually at temperatures of 38-50 DEG  C.; (7)-(9) mixtures of butadiene and acrylonitrile are copolymerized in the presence of the mixed methyl pentadienes in amounts up to 16 per cent of the other monomers, to soften the copolymers.

Title: Detection of video signal drop-out
IPC: H04N9/88
Filed: 1975-02-11
Abstract: 1495583 Television NORTH AMERICAN PHILIPS CORP 11 Feb 1975 [14 Feb 1974] 5745/75 Heading H4F A device which detects and compensates for sinusoidal waveform type disturbances in a video signal retrieved from a video disc store, comprises a delay 6, Fig. 1, of one line period to which the signal is applied. The delayed and undelayed signals are demodulated 2, 7 and differenced 8. A sinusoidal waveform dectector 9 receives the differenced signal and emits a pulse, having the same duration as the period of the sinusoidal waveform which is fixed dependent upon certain demodulator characteristics, upon detecting the disturbance. This pulse controls the switching of a unit 3 for selecting as output the signal delayed by one line period in place of the undelayed signal when the latter contains the disturbance. The pulse further conditions an inhibitor 11 to blank out the detector at the corresponding section of the next line to avoid subsequent selection of the delayed signal as output upon the occurrence of the disturbance therein which has previously been compensated for upon its occurrence in the undelayed signal. One embodiment of detector 9 and inhibitor 11 is described with reference to Fig. 5 (not shown). In the preferred embodiment only the luminance component of the incoming video signal is applied to the device but the detector output pulses are further employed to select the chrominance signal delayed by one line period (suitably adapted in the case of a PAL signal) instead of the undelayed chrominance signal since the latter then contains a disturbance corresponding to that detected in the luminance component.

Title: Digital scan converter
IPC: G01S7/298
Filed: 1977-02-11
Abstract: 1529281 Radar scan conversion HOLLANDSE SIGNAALAPPARATEN BV 11 Feb 1977 [16 Feb 1976] 05894/77 Heading H4D The radial to raster scan-converter described in Specification 1,388,233 using a single random access memory (RAM) to store the video data is stated to result in a severe limitation of the resolution of the final display, e.g. use of the RAM with 16 modules each storing 1024 bits limits the raster to 128 lines each of 128 elements. To overcome this limitation, the area A, Fig. 1 being scanned is divided into NXN sub areas, e.g. 7 x 7 and the data from each sub area is stored in a corresponding RAM, each storing 128 Î 128 bits. This results in an N fold increase in line and element resolution. The video data is fed from the radar, a radial line at a time into an input buffer 11, Fig. 2. The storage capacity required for the buffer is decided on assuming the azimuth of Fig. 1 is 45 degrees (i.e. a maximum length diagonal is being scanned), i.e. the line and element resolution X#2. The line data in buffer is serially divided into N portions and corresponding data bits of each portion are read out in parallel. An address generator 1 produces N sets of addresses for said N bits in said N sub memories, each address having its own frame of reference, a train of such addresses might be where m = 0, 1, 2,3,4... successively, #r = value of range increment. After storage of the sub area data in the submemories, the RAM is read out at the fast-flicker free rate (with switch 14 in other position), the parallel/serial outputs from the N sub memories being serially combined in a picture line memory 18 via a buffer register 16 to give complete raster lines.
