Abstract: 550,018. Vehicle bodies. KEEP, T. B. June 14, 1941. No. 7550. [Classes 103 (iv) and 108 (i)] [Also in Group XXXIII] A pillar for the body construction of motor vehicles, tramcars, tramcars, railway vehicles and aeroplanes comprises a base from which extends two wings one of which is normal to the base while the other for at least a part of its length is bent, bowed or inclined away from the first, a channel being thus provided to receive a wooden fillet to which sheeting may be secured. A double-deck vehicle body, Fig. I, comprises pillars 1, seat rails, 5, 6, waist rails 7, 8, cantrails 9, 4, light rail 10 and mould rail 11. Core panels 15, 16 extend from the lower and upper floors 3, 13 respectively to the rails 7, 6. To the exterior of the pillars metal sheeting is affixed. Figs. 2, 3 show sections at X-X, Y-Y of a pillar construction form comprising a metal sheet bent to form a base 17 and wings 19, 19a the wing 19 being bent outwardly at 19b. A wooden fillet 22 to which the metal sheet 21 is screwed is secured between the wings. In a modified construction, the wing 19 is bent inwardly at 19b and then inclined outwardly and in another construction it is curved or bowed outwardly from the goint 19b. Adjacent the windows a pair of Z-section members 27 bear on the fillet 22 and the base 17, piping 29 being interposed to prevent metal to metal contact and a cover strip 24 overlapping the flanges 28 of the members 34. The window panes 25 are retained by fillets 34 secured by screws 39 that enter hardwood or fibre strips 35. In an alternative construction, Fig. 4, stepped blocks 38 are secured to the base 17 and against the wings 19, 19a and are embraced by a channel-section flushing 42, the window panes 35 being retained by fillets 34 screwed to the blocks. The wings 19, 19a instead of being formed in one piece with the base 17 may comprise separate flanged members welded to the base. Specification 486,245 is referred to.

Filed: 1958-03-10
Abstract: 911,756. Valve and transistor circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 10, 1959 [March 10, 1958], No. 7617/58. Class 40 (6). A circuit whose Q is increased by positive feed-back comprises a series-resonant circuit L, C, positive feed-back being applied to a tap on the inductance L from a transistor T1 in emitter-follower connection. Resistor R in the feed-back path stabilizes the loop gain at less than that producing oscillation. As shown, three such circuits tuned to different frequencies are connected as narrow-band filters across a wide-band source V. The transistor may be replaced by a valve in cathode-follower connection, and the feed-back may alternatively be returned to a capacitive tap on the resonant circuit (Fig. 4, not shown). The arrangement may also be connected across a line or the output of an amplifier to act as a narrow-band rejector circuit (Fig. 7, not shown). Reference has been directed by the Comptroller to Specification 744,198.

Abstract: 700,278. Signs. GENERAL MOTORS CORPORATION. March 26, 1952 [April 2, 1951], No. 7700/52. Class 3(2) [Also in Groups XXXI, XXXIV and XXXVII] An indicator comprises a light source 56 an indicating element 28 and a prism 33 located between them so as to distribute the light over the indicating element. As shown in Fig. 2 the indicating element 28 is a transparent panel with opaque black indications marked on it, the panel being mounted in the front of a housing 35 which also supports the prism 33 so that it is immediately behind the panel. The housing also supports a tube 52 having a reflecting inner surface and at the remote end of which the light source 56 is mounted. Part of the prism is concealed from the light source 56 by a part 68 of the housing and the apex of the prism is cut away so that internal reflection in the prism of rays from the light source 56 illuminates the panel 28 uniformly. Three devices 12, 14, 16, Fig. 1, constructed as above are mounted on the dashboard of a motor car; the indicator 12 is controlled by a switch which is operated by a servomotor in the engine oil supply system, when the pressure is low so that the indicator 12 is then illuminated; the indicator 14 is controlled by a switch which is actuated when the parking brake is on so that the indicator 14 is then illuminated; the indicator 16 is controlled by an additional contact on the cut-out between the generator and the battery so that, if for any reason the cut-out is not closed by the generator so that the battery is not being charged, the indicator 16 is illuminated; all the indicator circuits are supplied through the ignition switch so that they do not operate when the ignition is switched off.

Title: Improvements in or relating to laminated structrues
IPC: B27D1/04
Filed: 1941-06-18
Abstract: 550,693. Laminated structures. KREMER, H. June 18, 1941, No. 7735. [Class 140] [Also in Group XXIII] Laminated and other built-up structures are made by impregnating the component parts with a thermo-setting resin, thereafter bonding them with a cold-setting synthetic resin or a thermosetting resin that can be set at a temperature lower than that necessary for the impregnating resin and finally subjecting to heat to set the impregnating resin. In the manufacture of a section of an aircraft fuselage, wood veneers are impregnated with a water-soluble phenol-formaldehyde resin in the A stage, dried and cut to shape. The frames and stringers are cut and bent to shape and preferably similarly impregnated. The assembly is united on a former by a methylated spirit solution of a resorcinol-formaldehyde resin made by heating the components in the presence of sodium hydroxide solution, neutralizing with acetic acid, cooling and adding an alcoholic solution triethanolamine. The structure is placed in a rubber bag, which is then exhausted and heated in a steam autoclave at 85 ‹C. to set the resorcinol-formaldehyde resin and advance the phenol-formaldehyde resin to the B stage. Finally the phenol-formaldehyde resin is converted to the C stage by treatment in a stoving oven at 150‹C. Alternatively the impregnating resin may be a water-soluble urea-formaldehyde resin and the bonding effected by a ureaformaldehyde resin modified by accelerators or set in the cold.

Abstract: 550,238. Treating cellulosic yarns with esterifying agents; coated fabrics: weltless cord fabrics. BRITISH CELANESE, Ltd. June 27, 1941, No. 8110. Convention date, July 24, 1940. [Class 2 (ii)] [Also in Group VIII] Tyre carcases and other articles are made of or from cellulosic yarns, filaments, or the like which have a surface of cellulose phthalate and are coated with a plastic material. Cellulose or regenerated cellulose yarns or filaments may be treated with a solution of phthalic anhydride in an organic solvent such as acetic acid. The regenerated cellulose yarns may be obtained by hydrolysis of cellulose acetate, nitrate, formate, propionate. butyrate, or other cellulose derivative. They may be obtained from cellulose ester yarns which have been stretched to increase their tenacity. The phthalyl radical may be introduced to the extent of 5-20 per cent. of the' weight of the cellulose. The materials may be boiled with the phthalic anhydride solution with or without a catalyst such as zinc chloride and paraformaldehyde mixture or toluene-sulphonic acid and formaldehyde. For the production of tyre cords, the superficially phthalated filaments or fibres are doubled together. The cords may be woven into fabric before coating or they may be coated directly with a plastic composition while in parallel relationship in the form of a warp sheet without the use of a weft. The cords or fabrics may be fed through a calender where they are coated with a rubber composition so as to produce a tyre carcase, No precoating with latex is required. Instead of rubber, the plastic material used may be a plasticized cellulose acetate or other cellulose derivative, or resin. Imitation leather, and balloon cloth are examples of other articles which may be produced.

Title: Improvements in or relating to the production of low carbon ferrochromium alloys
IPC: C21D3/04
Filed: 1949-03-26
Abstract: A method of desulphurizing ferrochromium containing 50 to 90 per cent chromium and undesirable amounts of carbon and sulphur, during the course of a decarburization process in which the ferrochromium in comminuted particle form, e.g. of fineness below 30 microns, is mixed with a comminuted oxidant such as chromium oxide or iron oxide and, preferably after pelleting, is heated at subatmospheric pressure, e.g. about 2 mm. mercury absolute, at a temperature sufficient to promote decarburization but below the fusion point of the material, the said method comprising supplying at least 10 per cent of the combined oxygen of the oxidant as silica and adding the oxidant in amount at least equal to that required for removal of the desired amount of carbon.  The pellets may be heated to a temperature in the vicinity of the solidus temperature of the ferrochromium but not exceeding 1300 DEG C. until the composition of the ferrochromium approaches the eutectic, then lowered to below the melting point of the eutectic, e.g. below 1265 DEG C. until the carbon content is below that of the eutectic, e.g. below 2.7 per cent, and the temperature is then increased to be in the vicinity of the solidus but below the liquidus, the temperature adjustment being such as to maintain porosity of the pellets.  The resulting highly compacted, uniformly porous, strongly cohesive, fine grained, nonfriable aggregate may contain 50 to 90 per cent chromium, not more than 2 per cent carbon and the remainder substantially all iron, and may have a density between 5.6 and 6.5 grams per c.c.  It may be used for introducing chromium into a bath of molten ferrous metal.  The production of a ferrochromium containing 66.89 per cent chromium, 25.54 per cent iron, 0.01 per cent carbon, 0.009 per cent sulphur, 6.2 per cent silicon and 1.12 per cent silica is referred to.

Abstract: 1346552 Signal generator PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 23 Feb 1972 [26 Feb 1971] 8340/72 Heading G4H A signal generator for use in the encoder or decoder of a pulse code modulation system with non-uniform coding comprises a source of clock pulses 200, a pulse counter 205 with a series of counting stages, a switching unit 208 connected between the source of clock pulses and the pulse counter and a resistance encoding network 204 coupled to the counting stages of the counter and to an analogue signal output 201 and is characterized in that the switching unit comprises a plurality of switching elements each of which is associated with an individual counting stage of the pulse counter for decoupling the stage from the preceding stages and coupling it directly to the source of clock pulses, and in which the switching elements are controlled from a control unit according to a programme. The generator also counts at 209 the number of clock pulses supplied to pulse counter 205 and produces this as the PCM word output on lines 202. The stages 205 of the pulse counter are connected byswitches 208 to clock pulse input 200. The output of each stage is fed to scaling resistors 206 and the analogue output is taken from the junction of these resistors and resistor 207. The clock pulse input also feeds the stages 210 of counter 209 and the parallel outputs 202 of these stages constitute the PCM word output. Control unit 213 provides signals on lines A to switches 208 and the control unit is fed by inputs Z which detect the various counts at which the slope of the transfer characteristic changes. In operation, clock pulses are first fed to stage 205-0 of the pulse counter and an analogue voltage builds up stepwise at 201. When the count at which the characteristic changes is reached switch 208-0 is moved to the solid position and, for example, 208-rk to the dotted position thus feeding 205-rk directly with clock pulses and building up the voltage at 201 by different size steps. At the same time, the total number of pulses supplied is counted in counter 209 and provided as output on parallel lines 202. In use in an encoder (Fig. 3), the input voltage signal is applied at 300 and compared at 302 with the voltage at 201. When equality is reached, the flow of clock pulses from 301 is stopped by gate 304 and the count in counter 209 is converted from parallel to series at 305 and appears at output 306 ready for transmission.
