Abstract: 595,423. Double-belt moulding machines. SHRIMPTON, W. J., and BRITISH ARTIFICIAL RESIN CO., Ltd. March 18, 1946, No. 3991/45. [Class 87 (ii)] [Also in Group VIII] An apparatus for making sheet materials from loose fibrous materials and a binder, has two moving conveyers, one above the other, made from interconnected platen members, the lower conveyer extending forward beyond the upper, a high frequency pre-heating device being situated above the extending portion. In passing between the conveyers the materials are pressed, e.g., by ramps which may be cam or hydraulically operated, and heated. The platen members of the caterpillar conveyers may have side plates or deckle bands to prevent side spread. In the operation of the apparatus shown in Fig. 1 the binder and fibrous material from the hopper y are fed on to paper from roll w in an amount controlled by roller z. The material is then preheated by the high frequency device 1, another paper facing being applied from roll u. Pressure is then applied by means of cam operated ramp r the material then passing by the movement of the conveyers to the burners q and s. finally being cooled in zone t. Continuous steel bands u and v may be used to prevent sticking, while side spread is prevented by side plates j. Specification 551,179, [Group VIII], is referred to.

Filed: 1924-02-20
Abstract: 235,613. Chemical Engineering & Wilton's Patent Furnace Go., Ltd., Wilton, T. O., and Wilton, N. Feb. 20, 1924. Endless-band conveyers, granular material carried on; draining.-In apparatus for drying and neutralizing ammonium sulphate during its manufacture, by feeding it upon a conveyer which carries it while it is being dried and neutralized by ammonia or other agents, the crude damp salt is carried on a belt, band, or chain through a casing sub-divided into chambers wherein it is successively neutralized', freed from excess moisture, and automatically delivered to a final drier. The conveyer may be perforated and provided with slats or the like. During the first part of the travel the excess mother liquor is drained off into a tank 20 by suction shoes such as 29, 29A disposed below that portion of the conveyer and connected to a vacuum pump 33. The sulphate having been neutralized is conveyed through a hot air chamber 49 to which hot air is supplied by a steam heater or coke furnace, or, as shown, by causing the hot waste gases from a saturator 11 for producing the sulphate to pass through pipes 43, 45 to an air heater 46, which heats air drawn through a pipe 47 and delivers it through a pipe 48 into the chamber 4'9. Suction shoes 35, 35A draw the hot air through the sulphate on the conveyer. The salt may be further dried by a steam chamber or pipes 37 fitted beneath the conveyer, after which it is delivered into a hopper 38 and through a final drier 39 provided with a revolving paddle and supplied with hot air. A shoot 40 delivers the dried granular salt into a hopper 41 above a weighing-machine 42. Means, for example a stirrer or paddle, may be provided for agitating the salt while on the conveyer. In another construction of the apparatus steam or hot gas is conveyed within a longitudinal flue at the bottom of the enclosed casing, the neutralizing agent being passed over the surface of the salt.

Title: Thermoplastic polymer sheets and articles obtainable therefrom
IPC: C08J9/34
Filed: 1964-02-05
Abstract: A process of forming a sheet of thermoplastic polymer foam comprises extruding a hot sheet of a foamable thermoplastic polymer composition, rapidly chilling the principal surfaces only of the sheet to prevent expansion thereof and to form outer skins while permitting the still warm core of the sheet to expand, the chilling being controlled to form a sheet consisting of a foam polymer core having a density of at least 18 lbs. per cu. ft., and a non-porous, smooth, tough polymer skin on either side of the core, the core comprising between 50% and 94% of the total thickness of the sheet and being integrally united to the skins, which have a substantially higher density than the core.  The preferred thermoplastic polymer is a styrene polymer containing more than 50% styrene. Other suitable polymers listed are cellulose ethers and esters, homopolymers and interpolymers of monomeric compounds containing the CH2=CH< group, e.g. olefins, vinyl halides, vinyl esters of carboxylic acids, vinyl ethers, unsaturated carboxylic acids and their derivatives and interpolymers of the above with a ,b -unsaturated polycarboxylic acids and their derivatives.  Polycarbonates, polyurethanes, polyethylene terephthalate or nylon may also be used.  Suitable foaming agents are volatile liquids boiling below 100 DEG  C.  The surfaces may be chilled by mixed air and water blasts, by air alone or by other inert gases, e.g. nitrogen, argon, carbon dioxide and helium at a temperature and a velocity sufficient to cool only the skin.  The invention is of particular importance in the manufacture of cups, but food trays, buckets, plates and face masks may also be prepared.

Abstract: 1480034 Sulphur dioxide removal DRAVO CORP 6 Feb 1975 [13 March 1974] 5061/75 Addition to 1457028 Heading C1A Sulphur dioxide is removed from a waste gas stream, in a wet scrubber 1 comprising a contact zone and a demister unit 2, by contacting the gas stream with an aqueous solution containing calcium salts and a magnesium ion concentration of 250-5000 p.p.m. and recycling a portion of the aqueous effluent to the scrubbing unit 1 and passing a portion to a thickener unit 21 to precipitate contained salts and passing at least a portion of the clarified thickener overflow to the demister unit 2. The utilization of a magnesium ion containing aqueous liquor results in a thickener overflow low in scale forming components, e.g. calcium sulphate or sulphite and thus permits the use of the thickener overflow in the demister without causing plugging. A preferred embodiment comprises passing the waste gas into the wet scrubbing unit 1 at 6 and introducing the scrubbing liquor at 7; the treated gas passes through the demister unit 2 wherein entrained solids and water droplets are removed and is discharged at 8. The effluent liquor is discharged from the scrubber unit 1 via line 9 to hold tank 10 where it is admixed with fresh scrubbing slurry, e.g. aqueous lime and magnesium hydroxide. One portion of the aqueous liquor from hold tank 10 is recycled to the scrubber unit 1 via line 19 and another portion to thickener tank 21 where salts such as carbonates, sulphites and sulphates precipitate out and the clarified liquor is discharged from the thickener tank 21 via line 29 to the conduits 5 and 5<SP>1</SP> which direct the thickener overflow to spray nozzles 3 and 4 for use as demister water.

Title: Improvements in or relating to signal generators

IPC: G06F1/02
Filed: 1966-02-04
Abstract: 1,134,056. Processing digital signals. MULLARD Ltd. 4 Feb., 1966, No. 5120/66. Heading G4A. A signal generator for generating a sequence of samples of the amplitude of a swept frequency wave comprises a number of accumulators 2, 3, arranged in series, the first of which is incremented by a signal from a clock 1, each signal also actuating an adder 8 which adds into accumulator 3 the contents of the previous one 2. At the beginning of each sequence the accumulators are set to fixed values by a setter 4 actuated by the clock, the capacity of the last accumulator and the magnitude of the fixed values being so chosen that the proportion of the last accumulator that is full, at any instant, corresponds to the particular phase of the wave at that instant. Determining means 9 then interpret the contents of the last accumulator and actuate a translator 10 which transmits the amplitude of the wave corresponding to that particular phase. If N denotes the power of the desired frequency sweep, then N + 1 accumulators in series are required, and to generate waves having different waveform but the same fundamental frequency, a number of translators all fed by one determining means, may be used. Alternatively if two waves of the same waveform but differing in phase, are required then a further accumulator incremented by an amount corresponding to the phase difference, may be used, the single translator receiving signals alternately from the said last and further accumulators. The output of the generator in the form of Sine and/or Cosine waves may form one input of the multiplier (22) (Fig. 3, not shown) of a Fourier analyser, the other input comprising the unknown wave to be analysed. The multiplier output is fed into an integrator having a recirculating store of period such that the integrated parts of a number of sequences, which parts correspond to a particular frequency, are separated to give the spectral component of the unknown wave which has this frequency.
