Title: Improvements in or relating to clad aluminium alloys and method of manufacturing same
IPC: C10K1/12
Filed: 1936-05-28
Abstract: A method of manufacturing clad aluminium alloys comprises applying to a basis alloy a covering layer of corrosion-resistant aluminium alloy containing between 6,5 per cent and 12 per cent of aluminium. Examples are given of such alloys containing respectively 7 per cent and 9 per cent of aluminium.  The high magnesium content tends to prevent diffusion of copper from the core alloy into the covering layer.  Difficulty in welding may be obviated by interposing between the basis alloy and the covering an intermediate layer of pure aluminium and effecting a diffusion of the covering and/or basis alloys into the intermediate layer.

Title: Improvements in rotary compressors
IPC: F04D19/02
Filed: 1936-05-29
Abstract: 479,427. Centrifugal and axial - fiow compressors. JENDRASSIK, G. May 29, 1936, No. 15192. Convention date, May 31, 1935. [Class 110 (i)] Axial-flow or radial-flow turbo - compressors with working and guiding rows of blades have the blade carriers formed with channels to conduct the boundary layer of gas from higher to lower pressure regions, the channels having discharge orifices formed to give the returning gas a direction component the same as that of the main flow. The inlet orifices may be directed perpendicular to or against the main flow. The channel outlets have a smaller area than the inlets, and the channels in any one stage have a smaller area than those in a higher-pressure stage. The guide blades may rotate or be stationary, and there may be two or more successive rows of rotating or stationary blades. The channels 68, Fig. 9, of the rotor 56 are formed under rings 58 carrying the rotor-blades 60 and clamped by rings 57 having channels and boundary rings 59. The guide-blades 61 are carried by rings 63 which with the rings 64 are grooved to form the channels 69 with boundary rings 65, all these rings being carried by member 62 which may rotate or be stationary. The channels may be formed by annular grooves in the casing walls with the rotor-blades projecting into the grooves. The free ends of the blades 83, Fig. 12, may be riveted to a crown-ring 86 which may carry auxiliary blades 87. The channels may have guide vanes 88, carried by the rings 81, 82 to increase the velocity of the returning gas. The rise of pressure within any row of blades may be dirninished without risk of detachment by subdividing the blades into several rows, or into one row, Fig. 8, with split profiles having one or more splits. The guide-vanes may be adjustable so as to contribute either a rise or a drop in the pressure or to keep the pressure unchanged. The Specification as open to inspection under Sect. 91 states also that to enable each blade to produce the same pressure in each of its portions, it is made narrower in the centre than at its ends and it is also centrally twisted to obtain a more favourable angle of impact with respect to the velocity at that portion. In Fig. 16 (Cancelled), a rotor-blade and a guideblade are shown in section at A on a central line and at B and C at their ends. The angle alpha<1> is greater than the angles alpha<2>, alpha<3> and the width t<1> less than the widths t<2>, t<3>. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in contact arrangements of electric switches
IPC: H01H5/02
Filed: 1942-10-29
Abstract: 560,264. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 29, 1942, No. 15208. Convention date, Oct. 31, 1941. [Class 38 (v)] A thermally-operated element acts on a pivoted contact base 31 to open a circuit. One fixed contact 24 is attached to a part of the casing but is preferably mounted on a flat bent strip spring, while the other 34 is carried on a spring blade 33 fixed to the base 31 and extending down behind a rigid magnetisable arm 35 secured at its upper end to the blade 33 near its connection with the base 31. The contact 34 is borne on a pin 34a which passes through the arm 35. A permanent magnet 28 is mounted so as to hold the contacts in engaged 'position. Successive positions taken up by the contact arm in opening and closing the circuit are shown at a ... e in the Figure. The pivoted base 31 is caused to rotate anticlockwise under the pressure of a thermostatically operated arm on the projection shown. The contacts remain held together by magnetic force while the spring bends at 37 until at a given point they snap apart, the spring straightening (position c). On release of' the thermostatic pressure the magnetic attraction on the armature 35 causes rotation of the base 31 in a clockwise direction, say from position c to position d, when the attraction overcomes the spring 37 to bring the contacts together (position e). During these operations, the movement of the contact 34 is first a sliding one downward (position b), which will break any weld on the contacts. On re-making the circuit, a weld may occur which will hold through continued movement clockwise of the base 31 until position a is reached. If no weld happens there will be a slight upward sliding movement from position e. Provision is made for the contacts to be held apart in one position of the knob adjusting the thermal device (not shown). Specifications 423,897, 424,746, [both in Group II], and 451,832 are referred to.

Title: Process and apparatus for the production of vinyl chloride from acetylene-containing gases
IPC: C07C17/08
Filed: 1961-04-28
Abstract: <PICT:0949985/C2/1> Vinyl chloride is produced by reacting a preheated acetylene-containing gas with hydrogen chloride in a first cooled reaction zone containing a mercury salt catalyst to produce a vinyl chloride-containing effluent, and then conducting the effluent through a second heated reaction zone containing a mercury salt catalyst of greater activity than the catalyst in the first zone to convert any residual acetylene to vinyl chloride, the first and second reaction zones being uniformly maintained at a temperature in the range 110 DEG  to 170 DEG C.  The acetylene-containing gas may be obtained in the cracking of petroleum hydrocarbons. Acetylene-containing gas mixed with dry hydrogen chloride passes through an inlet 2 (see the drawing) is heated by heat exchanger plates 3, and reacted in a first reaction zone 4 containing active carbon impregnated with mercuric chloride, the temperature being maintained in the above range by dissipating the heat produced in the reaction with cooling water flowing in a jacket 5. The effluent passes to a second reaction zone 6 containing active carbon impregnated with mercuric vanadate and heated by a jacket 7. Before leaving by outlet 10 the effluent passes through active carbon 8 cooled by a jacket 9 to absorb any mercury salt sublimed in the first or second reaction zones. Examples are given.

Patent GB-646651-A (GB)
Title: Method of manufacturing yarn from long fibres
IPC: D01G21/00
Filed: 1947-06-16
Abstract: 646,651. Preparing fibres for spinning. FAIRBAIRN LAWSON COMBE BARBOUR, Ltd., and LEHIGH SPINNING CO. June 16, 1947, No. 15758. Convention date, Sept. 30, 1940. [Classes 120(i), 120(ii) and 120(iii)] In the manufacture of yarn from long fibres, the fibre feed is regulated so as to form a fibre web of substantially uniform weight per unit length, the web is subjected to a plurality of combing operations each followed by the collection of the resulting sliver under a pressure greater than its own weight into a roll from which the sliver is fed to the succeeding operation, and the combed fibre is subjected to further treatment including at least one drawing operation and is finally spun into yarn. As shown hard or soft raw fibre 20 is fed on a feed table 25 from a barrow 21 on the weighing platform 22 of the feeding apparatus A described in Specification 646,652 at such a rate that a weight-indicating hand 54 shifts in synchronism with a hand 60 moving at a speed proportional to the speed of table 25. The fibre then passes to a Good's machine B where it is sprayed with softening .emulsion 80, the resulting sliver being collected in a roll 112 under pneumatic pressure of 60 lb. in a roll former C which is similar to that described in Specification 646,649, except that provision is made for supplying a foraminous woven-wire separator strip 117 to interleave the layers of sliver. Soft fibre rolls 112 are then placed in a conditioning room 160 under controlled temperature and humidity for 12-24 hours. A number of rolls are then assembled in a creel W which is similar to that described in Specification 646,650, provision being made for the separator strip to be taken up on a core 116a; the slivers are fed to a breaker card D, and the resulting single sliver is wound under 40 lb. pressure at 162. Rolls 162 are then fed from a creel 164 to a finishing card E to produce, under 40 lb. pressure, a roll 165 which is transferred to a creel 166 from which the sliver is passed through a drawing frame F and collected in cans at 167. The sliver may then receive three further drawing operations, after each of which it is collected in cans, and finally spun into yarn which is collected on cheeses. Rolls 112 of hard fibre are fed from a creel similar to creel W to a second Good's machine, the resulting sliver being wound under 60 lb. pressure in a roll former similar to C, a separator strip being again used. This step is repeated three times in succeeding machines, the resulting sliver being fed from a roll through a gill drawing machine and collected in cans, thence through a second drawing machine, and finally spun on a horizontal gill spinner.

Abstract: 370,721. Momentary-contact switches. WILLIAMSON, C. M., Litchfield Gardens, Willesden Green, London. May 29, 1931, No. 15785. [Class 38 (v).] A tube 1 is closed at one end by an insulating bush 14 carrying a fixed contact 12 arranged to co-operate with a movable contact 11 carried by an insulating bush 10 on a piston 3, normally urged against a stop pin 8, by a spring 9 which also serves to make electrical connection with the contact 11. To operate the switch, a piston 2 is moved to the left by means of a rod 5 which is then released. The piston 2 then returns under the action of a spring 4 and the air pressure moves the piston 3 to make contact at 11, 12. When the air leaks away, the piston 3 moves to the left due to the spring 9 and contact is broken. The period during which contact is made is controlled by adjustable nuts 6, 7 or by an adjustable air leak. In a modification, the piston 3 is replaced by a thin metal diaphragm.

Title: Method of and apparatus for washing hot gas
IPC: B01D47/06
Filed: 1936-06-05
Abstract: 481,184. Washing gases. FREYN ENGINEERING CO. June 5, 1936, No. 15792. Convention date, June 6, 1935. [Class 55 (ii)] Blast-furnace gas is washed by impinging it at a temperature above 100‹ C. against fixed surfaces sprayed with hot water so that the moisture content of the gas is increased, then bringing it to its dew point by impingement against baffles wetted by cooler water and finally passing it through a cooling stage in which turbulence due to change in direction is avoided and a fog is formed. Hot gas from a dust catcher enters tangentially at 12 a tower 10 containing in the lower part hurdles 13 of inverted tear drop section with hot water sprays 14 and more closely packed hurdles 16 in the upper part with cooler sprays 17. Gas passes at its dew point through pipe 32 to a condenser 11 and passes without turbulence between vertical parallel plates 33 with cold water sprays 34. The plates 33 may be corrugated. Moisture and fine dust are finally separated centrifugally by horizontal passage between arcuate plates 36g, the gas being deflected to the entry 36c by an inclined baffle 36b, and passing with acceleration in semicircular passages to the opposite outlet 36f and thence to pipe 44. The plates 36g are rubber coated and wetted by sprays 37, and their outlet end is curved more sharply. Water in the tower 10 is recirculated, about 20 per cent being led off to a clarifier 22, the water being replaced from a reservoir 26 and fed to the sprays 17. Water from condenser 11 is fed to the reservoir, which also receives water from the clarifier 22. The temperature of the sprays 17 is adjusted by varying the quantity from each source, so as to bring the gas to its dew point. The bottom of the tower has an arcuate baffle to give the gas a circular flow and has an annular curtain of spray at the inlet.
