Title: Improvements relating to electrical communication systems
IPC: H04B1/56
Filed: 1945-03-15
Abstract: 589,158. Two-way transmission. SIEMENS BROS. & CO., Ltd., and CHRISTIAN, D. A. March 15, 1945, No. 6573. [Class 40 (iv)] [Also in Group XL] In a system in which intelligence is transmitted by the use of an electron beam, transmission in both directions is accomplished by the use of a single beam in the cathode-ray tube CR. Speech incoming from the line E is applied to the subsidiary deflecting plates SVP and causes deflection of the beam in a vertical direction, thus reproducing the speech currents in the secondary of transformer TR6 and these are transmitted to line W via AMP2 and the hybrid HB2, no effect being produced in the secondary of TR4. Similarly, speech incoming from W is applied to plates SHP and causes deflection of the beam in a horizontal direction, the output, which is to transformer TR4 only, being applied to line E via AMP1 and hybrid HB1. These deflections are in addition to those produced by the main deflecting plates HP and VP. The beam continuously executes a rectangular trace over the target area at supersonic frequency due to the application of alternating potentials of symmetric triangular waveform to the main deflecting plates HP and VP with a phase difference of 90 degrees. In a modification (Fig. 3, not shown), these alternating potentials are dispensed with and the beam is normally stationary during silence. The system may be to the arrangements described in Specifications 567,451 and 567,674, to which reference is made in the Specification. Specification 589,159 also is referred to.

Title: Process and apparatus for the manufacture of cast irons of low carbon content
IPC: C21C1/00
Filed: 1935-03-04
Abstract: Low-carbon cast irons are produced in a cupola which is blown with a blast heated to a high temperature, e.g. 400-700 DEG  C., the working of the cupola being regulated so that the melting of the charge, formed mainly of steel scrap with proportions of fuels, and of siliceous and calcareous materials much higher than those normally used, takes place rapidly in a reducing atmosphere and in a zone of small height at a temperature of 1700-1800 DEG  C.  The proportions of carbon used is at least 50 per cent greater than that normally used, and the addition of limestone is regulated so as to obtain a slag in which the proportion of silica to lime is lower than 1, and the melting temperature of which is much higher than that of ordinary slags produced in cupolas.  The cupola used for the process is formed of a metallic cylinder sprinkled externally by the trickling of water, is provided with water-cooled twyers and is closed at its top by a charging bell below which is an outlet for the escape of gases. Part of the gases are supplied to an air heater in which the blast is preheated to the high temperature required.  The cast-iron produced is deoxidized and desulphurized and the slags may be used for the manufacture of cement.  Alloy cast irons may be produced by adding metals such as nickel or chromium to the charge.

Title: Apparatus for generating an electrical output signal of variable frequency
IPC: H03L7/16
Filed: 1975-02-06
Abstract: 1490731 Variable frequency generator SOLARTRON ELECTRONIC GROUP Ltd 6 Feb 1975 [14 Feb 1974] 6816/74 Heading H3A The output of a variable frequency oscillator 10 is controlled in coarse and fine stages to obtain a desired output frequency 168, the oscillator control circuit comprising variable delay means 30, 32 for producing signals 36, 38 having the same frequency but different phase and means 44 for producing a signal V representative of the phase difference therebetween, which signal is compared with a reference signal V RV  to produce an oscillator control signal 58. Coarse setting.-An approximation to the desired frequency is obtained by means of a manual adjuster 14 which causes f 0  to vary continuously until the required value appears on a display 194 (whose least significant digits are temporarily inhibited). Operation of adjuster 14 is detected at 100 to cause the inverted output from a gate 90 to disable a FET 64 in the control loop. Signal V is compared with V RV  at 72 : if they differ by more than an amount V L , logic 80-92 admits clock pulses 188 to a counter 96 whose output 98 controls the delay time of a delay circuit 32 (delay circuit 30 being fixed), gate 90 being enabled (even if 14 is released) while this is done; thus the main control loop 30-64 is already close to an equilibrium position when it is switched on (signal from gate 90 removed) for the fine adjustment. Fine setting.-V RV  is selected by means of a potentiometer 56: signal V is compared with V RV  at 50 and the difference signal 58 is applied via FET 64 to control oscillator 10 until equilibrium is reached. The outputs of 30, 32 are fed (via a phase shifter 112) to a further phase detector 110 which switches an inverter 62 into or out of the control loop so that small increases or decreases in f 0  result in positive- or negative-going changes respectively applied to the oscillator (to decrease or increase f 0 ), irrespective of whether the phase difference of 36 and 38 is leading or lagging. The output frequency fo may be frequency modulated by modulating V RV  with a varying frequency V M  from a potentiometer 122 ganged to a variable bandwidth filter 66. Oscillator 10 may be a varactor-controlled transmission line oscillator or a voltage- or current-controlled multivibrator circuit. Delay 30 may be a surface acoustic wave delay. Delay 32 may be a transmission line of variable length.

Title: Improvements in or relating to a gang mower
IPC: A01D75/30
Filed: 1945-03-19
Abstract: 616,255. Lawn-mowers. WORTHINGTON MOWER CO. March 19, 1945. No. 6873. Convention date, Sept. 15, 1942. [Class 6 (ii)] A gang mower comprises a series of units each consisting of a frame spring-mounted on a pair of pneumatic land-wheels and having rotary cutters driven from the wheels and mounted on frames supported and pivoting about the wheels. A lever 32 pivoting on a cross rod 11 has one end fixed to the cutter frame at 34 and has at the other end a spring 43 fixed to a chain 41, which passes over a non-slip pulley 37. The height of cut is varied bv turning the pulley which is locked in position by a pin 39. On striking an obstruction the cutter frame will swing out of the way, the spring 43 forcing it back into position. The units are formed in two rows, the front row units being hinged at 46 and 47 to each other. The hinge pin also engages a swivel bearing bracket mounted on the centre of each of the units in the second row. Thus the front and rear units are close-coupled making a framework which permits hinging only on axes extending in the direction of travel. The gang-mower is towed by a tractor and the arms 51 are connected by chains 55 to springs 54 fixed to the tractor to prevent the gang from swaying. In a modification a spring-wheel may be substituted for the pneumatic land-wheels. The pulley 37 may be dispensed with and the spring 43 connected direct to the main frame, the chain 41 also being fixed to the frame. Instead of comprising separate units the gang may comprise a rigid framework with land-wheels and cutters in similar positions to that shown in Fig. 1.

Abstract: 1435447 Carbon fibre preparation; acrylonitrile copolymers ASAHI KASEI KOGYO KK 15 Feb 1974 [24 Feb 1973] 7049/74 Heading C1A Carbon fibres having improved physical properties and requiring a shorter preparation time than hitherto, are prepared by the controlled carbonisation of copolymers of acrylonitrile (99À95-85%), and phosphonates of the general formula where R=H or CH 3 , A=-O(CH 2 ) x H 1 (x=1-4), B is a halogenated alkoxy group where the halogen is Cl, Br or I, n = 0-2, m = 0-2, and n+m = 2. Optionally a fluid co-monomer may be employed, including amides, esters and salts of unsaturated mono-or di-carboxylic acids, α-substituted acrylonitriles, vinyl ester of carboxylic acids, unsaturated sulphonic acids and their salts vinyl chloride, vinylidene chloride, styrene, vinylpyridine, &c., and other olefinic compounds. Copolymerisation is effected using free-radical initiators, in any liquid system, but preferably in aqueous emulsion or suspension. The copolymers are dissolved in either aqueous solutions of inorganic compounds, or in organic solvents, and the resulting solutions used to prepare stretch-orientated fibres by any of the known spinning processes. Following an optional heat treatment in an oxidizing atmosphere at 180-300‹ C. for 0À5 to 30 hours, the fibres are carbonized into carbon fibres by known methods at temperatures from 700-1800‹ C. in non-oxidizing atmospheres, and may be further converted into graphite fibres by further heating up to about 2500-2800‹ C. in non-oxidizing atmospheres. In one example, a copolymer consisting of acrylonitrile (98% by weight), bis-chloroethoxy vinyl phosphonate (1À5%) and sodium methallyl sulphonate (0À5%) were oxidized at 230‹ C. for 4 hours, and then converted into carbon fibres with a tenacity of 243/mm.<SP>3</SP> and a modulus of elasticity of 18À3 Î 10.<SP>3</SP> kg./mm.<SP>2</SP>.

Title: Improvements in process for producing hydroxy-ethyl cellulose in sheet form
IPC: C08B11/08
Filed: 1957-03-04
Abstract: Hydroxyethyl cellulose in sheet form is continuously produced by forcing an aqueous solution of an alkali metal hydroxide through a continuously moving sheet of indefinite length of dry natural cellulose in fibrous form to contact all the fibres with caustic alkali solution of about the same concentration and thereby effect uniform alkalization of the cellulose, removing from the moving sheet excess caustic alkali solution, then passing through the moving sheet ethylene oxide to react with the alkali cellulose and finally washing the moving sheet to remove residual caustic alkali and unwanted reaction products, the conditions in the alkalization zone and ethylene oxide reaction zone respectively being such that the proportion by weight of ethylene oxide reacting with the alkali cellulose is 0.1 to 2 per cent, based on the weight of the cellulose, and that the sheet of hydroxy-ethyl cellulose contains an appreciable proportion of material which has retained its original fibrous form due to the fibres not having been completely etherified, drying the washed sheet, and calendering the sheet to reduce its thickness and increase its density.  The caustic alkali solution may contain 1 to 6 per cent NaOH.  The cellulose sheet may be cellulose pulp, paper, cotton batting or cotton fabrics.  In the example a 6 per cent aqueous NaOH solution is forced through a continuously travelling paper web to yield alkali cellulose containing 40 per cent cellulose and 2 per cent NaOH.  The sheet of alkali cellulose is then led into a chamber in which ethylene oxide gas is forced through the sheet to effect etherification to a level of about 1 per cent with substantially none of the fibres remaining unreacted.  The sheet is then washed successively with water and a dilute aqueous solution of SO2.
