Title: Method of and apparatus for cleaning gases
IPC: B01D47/02
Filed: 1971-04-19
Abstract: 1324766 Apparatus for cleaning gases TECHNICAIR SA 19 April 1971 [14 May 1970] 24483/71 Heading B1R Dust-laden gas enters cleaning apparatus 1 through inlet 15, and passes down channel 14, over the surface of the cleaning liquid in the base of the apparatus and eventually leaves the apparatus by outlet 26, following the path shown generally by the arrows past various guides and baffles. As the gas passes over the liquid, it entrains and is partially wetted by the liquid. Deflector 17 is so shaped that the gas flow in chamber 35 diverges into two streams, part passing to outlet 26 while the rest flows vortically and is eventually drawn by the venturi effect through the gap between edges 16a, 17a of deflectors 16, 17, as the result of which it is thoroughly wetted. The liquid supplied to the apparatus through line 70 is controlled by differential pressure sensor 73. Various modifications allowing improved liquid entrainment are described (see Figs. 4-8, not shown). A symmetrical double flow apparatus is also envisaged (see Fig. 9, not shown), and the closed base of the apparatus may be replaced by a water seal (see Figs. 10, 11, not shown).

Title: Packaging of yarn and filaments
Inventor: OSBORNE WILLIAM FRANCIS
IPC: B65H54/80
Filed: 1952-10-01
Abstract: 730,795. Coiling yarns, &c. into containers. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Sept. 16, 1953 [Oct. 1, 1952 ; Sept. 7, 1953], Nos. 24570/52 and 24650/53. Class 120(3). A process for packaging rapidly moving yarns or filaments e.g. of a total denier of not less than 1,000, into containers comprises entraining the yarn in a stream of gas or vapour flowing down a tube and projecting the entrained yarn or the bundle of filaments into a container, the length of the tube, which is preferably metallic and flexible or spirally wound, being sufficient to prevent the disturbance of the individual filaments as they leave the tube. For a 1,000 denier multi-filament yarn at a speed of 2,000ft. per minute and an air speed of 6,000 ft. per minute disturbance is avoided when using a 30 inch tube of “ inch bore but not when the tube has a length of only 12 inches. Filament disturbance is avoided when conveying a tow of 3,000 denier at a speed of 2,000 ft. per minute with an air speed of 5,000 ft. per minute by using a 7 foot length of ¥ inch bore flexible tubing with rigid ends 30 inches long on either side of the flexible length. The individual filaments may be stuck together before entering the tube by means of a temporary adherent coating. The outlet of the tube may be reciprocated or oscillated across the open diameter of the container to cause the yarn or filaments to lie evenly in the container. The motion may be derived from cams and a pantograph linkage. Alternatively the tube may remain stationary and the container may be reciprocated and rotated. The container may be jigged.

Title: Counting device and circuit arrangement therefor for counting railway vehicles
IPC: B61L1/16
Filed: 1958-07-31
Abstract: 898,791. Counting-apparatus. WESTING- HOUSE AIR BRAKE CO. July 31, 1958 [Aug. 7, 1957], No. 24660/58. Class 106 (1). A counting device for use in a railway car routing system comprises sequentially actuated normally open and normally closed contacts and a plurality of impedance elements connected one in parallel with each of said contacts, the impedance elements being connected in series with one end terminal connected to a potential source and the other to earth, the contacts operating so that the normally open ones close and the normally closed ones open to maintain the total impedance between said terminals constant, and an output lead connected to a point between said terminals, such that the potential between the output lead and earth changes in accordance with the count registered. When storage information is available in a Route Storage Bank 14, a relay 1-2ADP is energized establishing a circuit via its contact a to energize the magnet AGMC of an auxiliary counter 11 every time a detector 12 registers the passage of a railway car axle thereby energizing a relay AZTP. In the counter 11 pairs of contacts a1, a2; b1, b2, &c. are successively actuated. When the fourth axle is detected, corresponding to a complete car, a circuit is completed over contacts e2, d1 to energize a reset relay AGRS which releases the magnet AGMC to reset the counter 11. Operation of the contact b of the relay AGRS completes a circuit for the drive magnet 1C1MC or 2C1MC of a counter 23 or 43 for the corresponding track 1 or 2 according to the state of contact a of a relay 1-2A1P. If a count of less than four is registered by the counter 11 when the contact a of the relay 1-2ADP closes, the relay AGRS will be energized over the intermediate contacts a<SP>1</SP>-d<SP>1</SP>, a<SP>2</SP>-d<SP>2</SP>, so that a second count is registered by the appropriate counter 23 or 43 for cars with more than four axles. Tens counters 24, 44 are also provided, closure for example of contact j1 energizing relay 1CRS to reset the counter 23 and over its contact C and energize the tens relay 1C2MC. Resistors are connected in parallel with the contacts of counters 23, 24, 43, 44. Thus for the counters 23, 24, the impedance from junction 25 and lead 20 to earth decreases linearly as the track fills and the impedance from junction 25 and lead 20 to lead 19 increases linearly. As described, a minimum impedance from lead 20 to earth is obtained when the counters 23, 24 register forty-two, due to the connections effected by the lead 41. The counters 43, 44 for the track 2 operate in a similar fashion. An output from the counters is fed over leads 17-20 to a computer which calculates the distance which each particular car must roll on the track before it is halted. Reset buttons 1TCB, 2TCB are provided to reset the counters 23, 24; 43, 44 when the associated storage tracks are clear of cars.

Title: Improvements in and relating to mist-producing apparatus
IPC: F41H9/06
Filed: 1935-09-04
Abstract: 464,134. Producing mist or fog. KRONENBERG, P. Sept. 4,1935, No. 24674. [Class 81 (i)] Mist or fog for military purposes or for plant protection is formed by bringing an oil, fat or other organic substance into contact with an oxidizing catalyst in presence of air or other oxidizing gas under such conditions that there is insufficient oxygen for complete combustion, so that the greater part of the organic substance is merely vaporized and forms a mist in the atmosphere. Organic mist - producing substances specified are crude paraffin oil, solid paraffin, lignite oils, crude petroleum jelly, naphthalene, anthracene, mineral oils in general, nitrobenzene, aniline, turpentine, oleic acid, tallow, tar, and pitch ; for horticultural purposes nicotine or pyrethrum mixed with solid paraffin may be used. The catalysts consists oxides of cadmium, cerium, vanadium, uranium, cobalt, nickel, manganese, chromium, copper, iron, or mixtures of these ; they may be prepared by heating salts of the metals with volatile acids and may be in the form of wire or granules or deposited on a carrier. The catalyst may be in finely divided condition and kept absolutely dry or, preferably, are heated before the organic substance is brought into contact therewith. In the form shown in the Figure a catalyst k, such as chromium oxide in small pieces, is arranged in an open tube s having a damper r to regulate the air supply. Oil is supplied from a vessel o, or solid paraffin,from a perforated tray t. The catalyst is first heated by burning benzine or alcohol thereon and after the flame has died out the oil is admitted and the air supply adjusted to maintain a temperature of 400 to 500‹ C. In a modification, the catalyst is arranged in a tubular vessel having a closed base except for an admission pipe for compressed air. In a further modification, a porous cylindrical case is coated or impregnated with manganese dioxide and filled with a mixture of solid paraffin with nicotine or pyrethrum. The case acts as a wick and is ignited and as soon as it glows sufficiently the flame is blown out and combustion and vaporization proceed without flame.

Title: Improvements in and relating to electric gas-blast switches
IPC: H01H33/91
Filed: 1935-09-05
Abstract: 443,416. Gas-blast switches. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Sept. 5, 1935, No. 24795. Convention date, Sept. 6, 1934. [Class 38 (v)] The arc drawn between the fixed and movable contacts 2, 3 is subjected to an air or gas blast produced in channel 6 by means of a compression chamber'4 and a piston 5, which is coupled to the movable contact 3, as by linkage 7, so as to be actuated only during the circuit-opening operation. According to the invention, the channel 6 is separated from the chamber 4 by means, such as an adjustable valve 8, which only releases the supply of air at a predetermined relative position of the contacts or at a given pressure in 4 corresponding to that relative position of the contacts. In this way, losses by leakage due to the imperfect fit of the rod 3 in the nozzle-contact 2 are reduced, and the valve can be adjusted to provide either a uniform flow, or a blast which is stronger at the commencement and then diminishes in intensity, or vice versa. The release of the supply of air may be effected by the engagement of the piston 5 with the valve-stem 9, as shown, or the valve may operate in dependence on the contact position, or the pressure in 4. The valve may provide an increased crosssection of outflow passage on decrease in gaspressure, so as to compensate for variation in the latter.
