Abstract: 863961 Liquefaction of gases HYMATIC ENGINEERING CO Ltd 12 Jan 1960 [23 Jan 1959] 2529/59 Headings F4H and HG13 Prevention of blocking of an expansion orifice 8 by frozen impurities such as water and carbon dioxide contained in compressed gas to be liquefied by expansion at said orifice after being cooled in a coil 11 in heat exchange with cold vapour resulting from the expansion is effected by passing the cold impurity-containing gas through a porous membrane 9 located adjacent and upstream of the orifice 8 and subjecting the gas stream to a relatively small pressure drop. The orifice 8 is inclined at an angle of between 30 degrees and 60 degrees to the longitudinal axis of the apparatus thereby directing the jet of liquefied gas against a porous angularly adjustable deflector 10 which in turn distributes  the cold liquid over a wide area at the bottom of a dewar flask 4 having on its outer surface photoelectric cells. The member 9 may comprise sintered metal, wire mesh or ceramic material of 5 micron pore size.

Title: Improvements in or relating to fluid absorbing compacted fibrous material
IPC: D04H1/70
Filed: 1964-01-22
Abstract: 1,057,462. Fibrous fabrics; paper. ANNE CO Ltd. Jan. 22, 1964 [Feb. 23, 1963], No. 2764/64. Headings D1R, D2A and D2B. A method of producing absorbent fibrous material suitable, for example, for use in catamenial appliances comprises subjecting a wet surface of compacted fibrous sheet material to intermittent pressure applied by means of a plurality of gas streams impinging intermittently on the surface of the sheet, so that a material is produced having a permeable facial layer with small zones which are more compacted and other small zones which are less compacted than an interior less permeable layer. The interior layer may lie between two facial layers the outer surface of one of which may be treated, e.g. with resin, paraffinic hydrocarbon, silicone or other water proofing compound to render the surface impermeable to liquid. Pulp sheet 1 is wetted on both surfaces by sprays 10 and is fed between travelling wire mesh belts 2 which serve to interrupt the passage of streams of air directed at the two surfaces of the sheet. Nozzles 3 carried by reciprocating arms 5 and supplied with pressurized air by tubes 14 supply the streams of air which tend to displace the fibres of the facial layer from between the wires of the wire mesh and to compact the fibres together under the wires. The treated sheet material is dried by means of a drier 4 and suitably folded or stacked. In an alternative arrangement wet pulp sheet is fed directly from apparatus in which the sheet is deposited to the section of apparatus in which it is subjected to the gas streams thus eliminating the need for sprays 10.

Filed: 1927-02-01
Abstract: 290,329. British Thomson-Houston Co., Ltd., and Dreghorn, H. Feb. 1, 1927. Alternating-current commutator machines.-An alternating-current commutator moto.r is arranged to run at a few definite speeds by being wound as an ordinary induction motor and by having a commutator winding connected to the secondary winding so that the voltage introduced into the secondary may, by suitable switching arrangements, cause the machine to run supersynchronously or subsynchronously as required. In the form shown, the motor is adapted for three speeds and comprises a primary winding P connected to slip-rings B, a regulating commutator winding R and a secondary winding S connected in star. With the connections as in Fig. 1, the machine runs subsynchronously and by connecting the secondary windings as in Figs. 2 and 3 respectively, it runs synchronously and hypersynchronously. Jf a be the ratio of effective regulating volts to effective secondary volts per phase at standstill and N the synchronous speed, the three no-load speeds with the connections as in Figs. 1, 2 and 3 are N (1 - a), N, and N (1+a) respectively. If the current be too great, resistances may be employed during the times when the motor speed is changing from one fixed speed to another. Power-factor correction at sub and supersynchronous speeds may be effected in known manner by rocking the brushes. The .Specification describes also connections whereby 6-phase commutation may be effected with the use of a 3-phase. resistance only.

Title: Improvements in and relating to the conversion of pig iron
IPC: C21C5/34
Filed: 1955-01-31
Abstract: A process for converting pig-iron to steel by blowing with an oxidising gas containing at least 30 per cent oxygen comprises preheating the blowing mixture, during at least part of the process after the carbon has been reduced to at least 1.5 per cent, to such a temperature that the weight of reactive oxygen passing through each tuyere per minute does not exceed 1 kg when the mixture is oxygen-enriched air or 1.4 kg. when the mixture contains oxygen and carbon monoxide.  The mixture, or one or its constituents may be heated before or after the blower and the heated mixture may be used before the carbon has been reduced to 1.5 per cent.  The method of calculating the temperature required under different conditions is given.

Title: Improvements in and relating to the measurement of moisture
Inventor: JASON ALFRED CHARLES
IPC: G01N27/22
Filed: 1952-02-04
Abstract: <PICT:0732969/III/1> <PICT:0732969/III/2> A moisture-sensitive unit comprises an aluminium wire 12, Fig. 1c, part of whose surface is anodized to form a thin layer 11 of aluminium oxide, which is almost completely covered with finely-divided graphite 13, so that the conductivity and/or capacity between the aluminium wire 12 and the graphite coating 13 is affected by the humidity of the atmosphere and may be measured. In one form of measuring circuit (Fig. 2, not shown), the sensitive unit, in conjunction with an interrupter operating at constant frequency, is alternately charged by a battery and discharged through a meter whose <PICT:0732969/III/3> deflection is proportional to the capacity, and hence indicative of the moisture absorbed by the aluminium oxide from the atmosphere.  In another measuring circuit, Fig. 3, the unit 26 is one arm of a D.C. bridge, the unbalance current being amplified by a push-pul amplifier with negative feed-back, and measured at terminals T.  The unit may be made in sheet form, and may be used against a surface by covering it with a layer of insulating plastic.  Calibration.-A saturated air source at a controlled temperature is obtained by pumping air at 41, Fig. 4, into a saturator 42, where it passes through a diaphragm 45 of filter paper dipping into a reservoir 46 and through an outlet pipe 47 to affect the sensitive unit 49.  The temperature of the saturator 42 is maintained constant by a circulating liquid at a thermostatically controlled temperature in the jacket 43.  The apparatus may be used to measure partial pressures of the vapour of alcohol, acetone, ether, naphthalene, acetamide, ammonia, methylamine, dimethylamine, and trimethylamine.  It may also be used to measure the salinity of salt solutions, and in the measurement of moisture content of foodstuffs, building materials, timber and raw materials generally.  Specification 559,240, [Group XXXVI], is referred to.

Shaft 9 is slidable horizontally by rod 10 in member 12 (Fig. 2) which is slidable vertically along shaft 11 to maintain the knife at a constant angle. To adjust the knife in Fig. 1, servomotor 15 moves member 12 vertically causing shaft 9 to slide horizontally and carrier 4 to rotate. Alternatively the carrier 4 could be rotated directly by the servomotor. In Figs. 3-6 (not shown) the connections between shaft 9 and shaft 11 are modified. Knife 6 may be axially movable on shaft 9 by a second servomotor 17 (Fig. 5).

Abstract: 469,812. Projection screens. DENTON, J. M. Jan. 31, 1936, Nos. 3000 and 26195. [Class 97 (i)] In a perforated screen of woven fabric, the sections of the screen are joined together by placing their adjacent edges side by side so as either to abut or overlap, and holding them by adhesion to a strip of openwork or perforated material arranged so that its perforations coincide with those of the screen. The strip may comprise a lace netting held by gum or cellulose solvent, and blocking of the perforations by the solvent may be prevented by a blast of air. As shown, to facilitate joining, the two sections A, B are held on a backing D carrying pins E to engage the perforations. The joining strip G, coated with a suitable adhesive, is threaded over the pins E and pressed against the sections A, B until fixed, when the backing D may be removed. A second strip, which may be imperforate, may be placed on the opposite side of the screen. Alternatively a grid strip K, Fig. 10, may be employed, the transverse members K<1> of which are coated with adhesive ; the lateral members K<2> can be cut away after adhesion of the members K<1>.
