Title: Method for the prevention of felting shrinkage in assemblies of  wool or other keratin fibres
Filed: 1971-07-08
Abstract: 1361243 Reducing felting shrinkage of wool COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION 8 July 1971 32150/71 Heading DIP A process for reducing felting shrinkage in a textile material of wool or other keratin fibres processed on the woollen system, comprises treating the material with a reducing agent, rinsing to remove excess reducing agent, and subsequently treating with a cross linkable acrylic polymer -in conjunction with a cross linking agent therefor, and heat curing. The 'reducing agent may be sodium bisulphite, metabisulphite, sulphite or hydrosulphite, sodium sulphide in alcohol or thioglycollic acid or a salt thereof. The cross-linkable acrylic polymer may be formed from monomers such as acrylic and methacrylic acids and their salts, amides, esters and nitriles. Specified are methyl, ethyl, n-butyl and 2-ethylhexyl acrylates; methyl, ethyl, n-butyl, isobutyl, lauryl, stearyl, hydroxyethyl, hydroxypropyl, dimethylaminoethyl and t-butylaminoethyl methacrylates; and methylol acrylamide. The hardness of the polymer may be adjusted by varying the proportions of the monomers, or by copolymerizing with styrene, vinyl chloride, or vinyl acetate. Specified cross-linking agents include: methacrylic acid, hexamethoxymethylmelamine, 1-hydroxymethyl - 3 - 5 - dimethoxymethylmelamine, N, N'-bis (methoxymethyl) urea, 4, 5- dihydroxydimethylolethyleneurea, N, N'-dimethylol urea, tetramethylol acetylene diurea, N, N'-dimethylol ethylene urea, N, N'-dimethylolpropylene urea, 4-methoxy-5, 5-dimethyl-N, N'-dimethylol propyleneurea, tris (1-aziridinyl) phosphine oxide, and vinylcyclohexene dioxide. In the examples the reducing agent is applied to a plain weave woollen, blanket or flannel from 3% solution at 60‹C. The polymer is applied as a 2.5% emulsion containing 5% of the cross linking agent. The material is dried at 100‹C for 10 min and cured at 130‹C for 10 min.

Convention date, Dec. 1, 1934. [Class 135] In a regulating valve for heating-systems or the like having a guard cap g which shrouds the valve spindle d, the packing gland f, and the lock nut c of an auxiliary pre-setting sleeve a, the unauthorized removal of the cap g for the purpose of adjusting the sleeve a is prevented by a threaded sleeve h in the throat of the cap, this sleeve being operated by a suitable key so as to abut directly or indirectly through an intermediate member, a part of the valve such as the gland nut f, so that the cap is slightly raised and the bayonet or other connection k by which the cap is secured to the valve is locked or clamped in position. The nut c is formed with cams or projections l for engagement with two inclined ridges k in the cap g, which form a bayonet connection. The sleeve h has internal grooves i for engagement by the key. Fig. 5 shows a form in which the sleeve h is rotatably connected to a bell-shaped member n having a serrated lower edge cooperating with projections l<1> on the nut c. The bell n has projecting ribs p taking into recesses in the guard cap. In this way rotation of the guard cap is also prevented. The Specification as open to inspection under Sect. 91 refers also to a screw-threaded connection between the guard cap and the valve. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to directional radio aerial systems
Inventor: BATES RICHARD HEATON TUNSTALL
IPC: H01Q3/32
Filed: 1956-10-23
Abstract: 817,770. Aerials. DECCA RECORD CO. Ltd. Jan. 23, 1958 [Oct. 23, 1956], No. 32345/56. Class 40 (7). [Also in Group XL (b)] A directional aerial of variable directivity comprises a strip transmission line consisting of an inner conductive strip together with spaced shielding plates, the effective spacing of one or both of the plates and the strip being variable, and a number of radiator elements. In one embodiment the strip conductor 40, Fig. 11, is associated with a fixed shielding plate 42 and a moving shielding plate which comprises a rotating eccentrically mounted conductive cylinder 43. A slab of dielectric 41 is held between the strip 40 and the fixed plate 42, this ensuring that the phase velocity of a wave in the line is different from that in an air-spaced line; alternatively a number of metal posts may be used. Conductive plates 44, 45 are provided to reduce the leakage of signals from the sides of the line and one of these plates supports a number of unipole radiators 46 along the length of the line so spaced that the radiation forms a directional beam. The radiators may alternatively be mounted in the position shown dotted at 47 or may comprise slots in one of the walls 44, 45 instead of the unipoles shown. As the cylinder 43 rotates the phase velocity of a wave in the line varies cyclically and the several radiators are excited in cyclically varying and relatively different phase, so that the directivity of the aerial varies cyclically. In a second embodiment the effective spacing of the shielding plates 51, 52, Fig. 13, is varied by inserting dielectric between the strip 50 and the plates. Thus a rectangular block of dielectric 54 has cut in it a slit which straddles the strip 50 the amount of straddling being varied cyclically by moving the block 54 to and fro by means of an oscillating unit 56. Unipoles 62 are the radiator elements.

Title: An improved process and apparatus for separating magnesium, beryllium, and like metals which sublime from their ores and compounds
IPC: C22B26/22
Filed: 1935-11-27
Abstract: In a process for producing magnesium, and like metals which sublime, from their ores or compounds, the ore in subdivided form is mixed with an iron alloy carbide, the latter being heated by high-frequency currents to the temperature at which the reduction of the ore and the distillation of the metal takes place, the reaction being carried in a continuously evacuated container, the pressure in the latter being maintained below the dissociation temperature of the ore being treated.  When the alloy carbide used is ferro-chromium having a high carbon content, e.g. of the order of 10 per cent, a decarburized ferro-chromium is also produced.  The pressure in the container is not above 2 mm.  In an example, chrome ores containing an appreciable percentage of magnesium oxide are mixed with ferro-chromium alloy having a higher carbon content and treated, magnesium and a low-carbon ferro-chromium alloy is produced.  Other alloys such as ferro-manganese may be used as reducing agents.  The process is carried out in the apparatus described in Specification 466,763.

Abstract: 911,932. Dish-washing machines. MODERN EQUIPMENT CO. Ltd. Sept. 19, 1961 [Sept. 26, 1960], No. 32941/60. Class 138 (1). In a dish-washing machine having a reservoir of a size sufficient to hold the amount of water necessary for the washing and rinsing operations, the bottom of the reservoir is located above the bottom of the washing compartment so that water may be discharged from the reservoir under the action of gravity. The reservoir 14 is filled with water through inlet pipe 15, and when the float 18 has risen to a predetermined level it closes a switch 19 in the circuit of a motor 30 and a heater 17 in the reservoir 13. Any excess water overflows into the washing compartment 13 through an outlet pipe 43 and thence through a drain 28 past an open valve 29. The door 12 is then closed to close a safety switch (not shown) to energize the heater 17. When the water has been heated sufficiently a thermostat 17a energizes the motor 30. The latter operates a pump 21 for circulating water via a sump 22 to a rotary sprayer 20 for discharge over dishes in racks (not shown). The motor 30 also rotates a cam 31 which first closes a switch to maintain the motor in operation independently of the switch 19, and actuates a solenoid switch 37 to open an inlet valve 24 to allow hot water to flow from the reservoir 14 into the washing compartment. The washing operation continues until the cam 31 engages a lever 42 to open the outlet valve 29. After the necessary draining period the inlet valve 24 is again actuated by the cam 31 to admit rinsing water to the washing compartment 13. This is drained after the required first rinsing period, and a second rinsing period is initiated by the cam 31 which ceases when the cam 31 deenergizes the motor 30. The sump 22 is provided with coarse and fine mesh filters 25 and 26 respectively.

Abstract: 1,037,429. Variable-ratio gearing. MAYBACH-MOTORENBAU G.m.b.H. Aug. 21, 1963 [Aug. 23, 1962], No. 33157/63. Heading F2D. A hydromechanical variable-ratio gear corn prises hydrodynamic torque converters 14, 16 connected in parallel and preceding a constantmesh spur gearing providing two forward and two reverse ratios. The common turbine shaft of the torque converters, which forms the input shaft of the spur gearing, can be braked by a hydrodynamic brake 44 to facilitate changing the ratio of the spur gearing. The transmission is particularly intended for diesel railway locomotives, the engine driving a shaft 10 geared to a shaft 13 driving the impellers of the converters 14, 16, the turbines of which are fast on a shaft 20 carrying the rotor 47 of the hydrodynamic brake 44. For the lowest speed range converter 14 is filled and converter 16 empty and drive is transmitted from the turbine shaft 20 through gears 22, 23, an engaged clutch 34, 35, gears 28, 27, an engaged clutch 42, 38 and gears 29, 31, 33 to a final output shaft 32. A second speed range is obtained by emptying converter 14 and filling converter 16, the ratio of the spur gearing being unchanged. To obtain third speed range, converter 14 is filled and converter 16 emptied, and clutch 34, 35 is disengaged and a clutch 36, 37 engaged so that the drive is transmitted from the shaft 20 through the engaged clutches 36, 37 and 42, 38 and through gears 29, 31, 33 to the output shaft. During this shift the hydrodynamic brake 44 is filled to slow the shaft 20 to facilitate engagement of the clutch 36, 37. All the clutches may be of a baulked dog type described in Specification 683,503. The top speed range is obtained on emptying converter 14 and filling converter 16. In a modification the converter 16 may be replaced by a hydrodynamic coupling. For reverse speeds clutch 38, 42 is disengaged and a clutch 39, 43 is engaged to clutch a gear 30 to the gear 28, the gear 30 meshing the gear 31 so that various speed ranges can be obtained by selectively filling converters 14, 16 and selectively engaging clutches 34, 35 and 36, 37.
