Abstract: 301,689. Knorr-Bremse Akt.-Ges., and Uhlmann, A. April 3, 1928. Addition to 295,544. Surface treatment with liquid materials.- Relates to the vehicular apparatus claimed in the parent Specification for spraying tar or the like on roads by means of air under pressure supplied by a compressor 2 which is driven by the propelling engine 1 and mounted on a tractor, the compressed-air tank 5 and the tar tank 6 being carried on a trailer 3 and the suction of the compressor being used for filling the tar tank. According to the present invention, a single pipe 10 leading to the tar tank can, by a three-way cock 11, be placed either in communication with the compressed air tank or with the suction side of the compressor. Further, instead of a float valve to prevent overflow from the tar tank from passing to the compressor, a spring-closed atmospheric valve 15, Fig. 2, situated in a casing 20 is opened by the weight of tar flowing into a vessel 13 to interrupt the suction in the pipe 10 when the tar tank is full. A solvent in a container 17 may be forced by the air pressure in the tank 5 through the spray pipes for cleaning purposes.

Title: Improvements in or relating to demodulators for pulse amplitude modulated electric signals
Inventor: MCDONNELL DENNIS
IPC: H03K9/02
Filed: 1952-04-22
Abstract: 711,409. Pulse modulation circuits. GENERAL ELECTRIC CO., Ltd. April 22, 1953 [April 22, 1952], No. 10167/52. Class 40 (5) Amplitude modulated pulses are demodulated by a circuit in which a cathode-follower valve 1 feeds the positive pulses from its load resistor 2 to charge condenser 5 through the normally non- conducting diode 4. The voltage across condenser 5 is applied to the output cathode-follower valve 6. In the intervals between pulses, a diode 9 becomes momentarily conducting due to the sudden drop in its cathode potential derived from the cathode of valve 1 through condenser 8, so that the charge on condenser 5 is shared with condenser 8. Thereupon diode 9 reverts to its normally non-conducting state and condenser 8 partially discharges through resistor 11 to a voltage determined by the level of the output signal across cathode resistor 7 of valve 6, before the next applied pulse causes the sequence to recommence. The amplitude of the modulation component in the output signal is thereby enhanced.

Title: A process for the production of sulphur dioxide from sulphates
IPC: C01B17/50
Filed: 1957-03-29
Abstract: <PICT:0837027/III/1> Sulphur dioxide is produced by conveying granulated material, comprising a metal sulphate and optionally a solid reducing agent, e.g. sulphur or carbon, in an amount insufficient to effect complete reduction to sulphite or sulphur dioxide, on a moving grate in the form of an endless conveyer through a three-stage heating and reduction system at each stage of which hot combustion gas is passed through the solid, exhaust gas from the second and third stages being passed to the first stage and exhaust gas from the first stage being passed for recovery of sulphur dioxide, the conditions being such that the exhaust gas from the first stage contains free oxygen, the sulphate is partially reduced in the second stage to produce sulphur dioxide, and the sulphate is substantially completely reduced in the third stage to produce sulphur dioxide by reaction with the hot combustion gas passing therethrough.  Inert gas may pass through the solid in the second stage.  The exhaust gas from the third stage may pass to the first stage via the second stage.  Air may be added to exhaust gas before passing to the first stage.  The combustion gas may be produced by burning coal dust, coal gas, oil, or sulphur. Sulphates which may be used are ferrous, magnesium, calcium and aluminium sulphate.  A mixture of calcium sulphate and clay, in which case cement may also be produced, and a mixture of sodium sulphate and aluminium sulphate or alumina, in which case sodium aluminate may also be produced, may also be used.  The temperature in the first stage may be 500-800 DEG C., that in the second 900-1200 DEG  C., and that in the third up to sintering temperature. As shown, sulphate-containing material is passed from a granulating device a via a hopper b on to a conveyer belt d which conveys the material through three separate heating zones I, II and III, each surmounted by a hood into which fuel is passed from pipe c and air for combustion from pipe p.  The air for combustion is preheated before passing into the hoods by being drawn through the hot residue on belt d by pump l.  The exhaust gas from zone III is withdrawn at k and is partly recycled to zone III at g and is partly passed to zone II at f.  The exhaust gas from zone II is withdrawn at h and is passed to zone I at e.  The exhaust gas from zone I is withdrawn at i and is passed through hopper b.  In a modification (Fig. 2, not shown), the lower halves of zones II and III are combined and exhaust gas from both zones is withdrawn through a single outlet and is partly recycled separately to zones II and III at f and g respectively and is partly passed to zone I at e.

IPC: B23K9/073
Filed: 1968-03-04
Abstract: 1,181,944. Control of D.C. motors. AIR REDUCTION CO. Inc. 4 March, 1968 [3 March, 1967], No. 10396/68. Heading H2J. [Also in Division G3] In a consumable electrode arc-welding system the electrode feed speed is automatically varied to compensate for arc current variations thereby to maintain the arc current constant at a predetermined value. As shown, a consumable electrode 20 is fed into an arc 34 by rollers 26, 28 driven by an electric motor having an armature 30; arc current variations are detected by a Hall-effect sensor 112 the output of which is applied over an amplifier 118 and a resistor 120 to one input of an operational amplifier 80 having a second input derived from a sawtooth generator 58, the arrangement being such that the output from the amplifier 80 is in the form of pulses having a pulse-length which varies in inverse proportion to the arc current variations. These output pulses are applied over a voltage divider 46, 48 to control the switching of transistors 40, 42 connected between a D.C. source 36 and the armature 30 of the feed motor, which thus receives unidirectional energizing pulses having a duration dependent upon arc current; the speed of the motor is proportional to the pulse-length, and thus the electrode is fed into the arc at a speed which varies to compensate for arc-current variations. The initial feed speed at start-up is determined by the adjustment of a potentiometer 100, associated with the amplifier 80, which sets the pulse-length to a suitable value when no arc-current is flowing. The armature 30 is shunted by a diode 44 which guards against current reversal in the motor and which protects the transistors 40, 42 against excessive voltage should the motor field collapse.

Title: Improvements in the manufacture of films
IPC: A24C5/56
Filed: 1929-04-04
Abstract: 334,271. M³nch, C. April 4, 1929. Cigarettes.-A non-transparent composite film of cellulose ester, especially cellulose acetate, for use in tipping cigarettes comprises a very thin layer in which the colour or pigment if present is in insufficient quantity to destroy its waterproof character, and a very thin layer containing sufficient finely divided pigment to render it substantially non-waterproof and give it a matt surface. The film as a whole is waterproof and non- porous, but, owing to the matt surface and porosity of the non-waterproof layer, it may easily be united to the paper of a cigarette by means of an aqueous adhesive. The film may be made by casting one of the layers as a solution upon a surface from which it can afterwards be stripped, allowing it to dry, casting the other layer thereon, allowing this to dry, and finally stripping the united layers as a single film. The pigment in the waterproof layer may consist of dyestuffs, mineral pigments, or metal powder, and the finely divided filler in the non-waterproof layer may be barytes with colouring matter if desired. In an example, the waterproof layer contains 2 parts by weight of bronze powder to each part of acetyl cellulose, i.e. about 1 volume of bronze powder to 3 volumes of acetyl cellulose, and the non- waterproof layer contains about 1 volume of mineral pigment to 1 volume of acetyl cellulose. Reference has been directed by the Comptroller to Specification 337,501.
