Title: Improvements relating to electric heating elements
IPC: H05B3/50
Filed: 1944-11-06
Abstract: 592,124. Electric heating resistances. SIMPLEX ELECTRIC CO., Ltd., HULBERT, C. LACY-, and BARTON, A. V. Nov. 6, 1944, No. 21680. [Class 39 (iii)] [Also in Group XXII] A method of compacting an insulating material 12, such as fused magnesia, in which a heating resistance 10 is embedded in a metal tube 11, comprises pressing the tube, between the inner ends of its end plugs, with suitable dies 19, 20 which move transversely to the tube so as to form longitudinal ribs 46. Temporary end plugs which may be of vulcanized rubber are provided, with heavy-section terminal connections, as at 13, passing through them. One end may be permanently plugged. Thus, a sealing and insulating washer 15 is inserted and may be of glass fused to the tube, followed by an insulating plug 16, e.g. of steatite, having indentations 17 into which parts 18 of the tube are depressed. For long lengths of tube, the dies are closed intermittently and the tube is fed therebetween, only when the dies are open, in steps that are less than the length of the dies, to compress the tube throughout its length except for the ends.

Title: Improvements in or relating to telephone station apparatus
IPC: H04M1/274
Filed: 1962-06-05
Abstract: 982,952. Impulse transmitters. GENERAL ELECTRIC CO. Ltd., A. E. HARROLD, and C. S. SMITH. July 8, 1963 [June 5, 1962], No. 21709/62. Heading H4K. Apparatus for calling frequently wanted numbers comprises a cam 54 which is slid able on but keyed to a vertical shaft 57 and which for each digit rotates clockwise (Fig. 2) until it engages a stop on an index member, the appropriate number of impulses being sent on its return movement. As shown the index members consist of rows of pins 24 . . . 35 which pass through holes in cylinders 5, 6 and have flat faces 36 forming the stops. To register a number a lever 97 is depressed to the position shown (Fig. 1), thus coupling the normal dial 3 through a cam assembly 92 to a bar 110, which cooperates with a finger 108 slidable on a vertical shaft 109. Actuation of a push button (not shown) energizes a motor 10 to rotate the cylinders 5, 6 to bring the appropriate row of pins opposite the finger 108, which moves one step upwardly before each rotation of the dial 3, so that each digit is registered by a measured inward movement of the corresponding pin. A lever 125 enables the finger 108 to be stepped without operation of the dial, in order, if required, to provide a long interdigital pause, and a cancelling bar 4 actuated by a knob 130 serves to restore any displaced pins to normal before dialling. To transmit, the relevant push button is actuated with the lever 97 in the raised position. In this case the cylinders 5, 6 are rotated by the motor 10 to bring the appropriate row of pins opposite the cam 54. For each digit to be sent a motor 58 operates to rotate the cam 54 clockwise (Fig. 2) until it engages the flat face of the displaced pin. The motor then reverses, and impulses are sent during the return movement of the cam. Before each movement the cam is raised one step on its shaft 57 to bring the pins into effect successively. Finally a release relay energizes to restore the apparatus. In modifications, which are not susceptible to setting by dialling, the rows of pins are replaced by detachable comblike structures having teeth of different lengths according to the values of the digits to be transmitted. The circuits of the push buttons, motors, &c. are described with reference to Fig. 3 (not shown). Specification 837,033 is referred to.

Patent GB-341897-A (GB)
Title: Improvements in the production of artificial filaments, threads, films or other materials
IPC: D01F2/28
Filed: 1929-07-17
Abstract: Artificial filaments, films, or the like of reduced lustre are produced by incorporating with the spinning solution, titanium oxide or mixtures or compounds thereof in the finely divided form. The filaments &c. may be produced by wet or dry spinning processes, and the invention is particularly applicable to spinning solutions containing cellulose acetate or other esters or ethers of cellulose. The titanium oxide which is present, for example, from about 0,5 to 5 per cent calculated on the weight of the basic material of the spinning solution, may be incorporated by any suitable means, for example, an aqueous paste of the pigment is worked up with part of the solvent used, and the paste so obtained, in which the water is partially or completely replaced by the solvent, is directly incorporated in the spinning solution.  When grinding the titanium oxide in the presence of liquids it is preferable to work in the presence of a dispersator and/or protective colloid such as Turkey red oil, and/or in the presence of oils such as oleic acid, linseed oil, or olive oil. The aqueous or oily paste may then be worked up with part of the solvent used for making up the spinning solution. The titanium oxide, alone or in admixture or in compound form, when obtained by precipitation, should be subjected to calcination at temperatures, for example, of from 600 DEG  to 1100 DEG  C., and if desired, in the presence of calcium phosphate to inhibit colour change.  Examples of admixtures to the titanium oxide are: zinc oxide or carbonate, boric acid or a borate such as barium or calcium borate, and also colour correcting or modifying substances.  Suitable compounds of titanium mentioned are calcium and barium titanate. According to the Provisional Specification, finely divided pigments other than titanium pigments may be used in the process.  The following mixed titanium pigments are also mentioned:-titanium oxide and silica; titanium oxide, magnesia and silica; titanium oxide, silica and a silicate.  Specifications 326,461, 326,462, 328,247, 333,504 and 334,195, [all in Class 2 (ii) Cellulose &c.], are referred to.

Patent GB-739817-A (GB)
Title: Detergent compositions
IPC: C11D1/14
Filed: 1953-08-17
Abstract: In the manufacture of detergent products by treating an alkylaryl compound with an excess of a sulphonating agent and neutralizing the mixture, an addition of methyl alcohol is made to the mixture before it is neutralized, whereby a salt of methyl sulphate is formed in the mixture on neutralization.  The tendency of the dried products to cake is thus reduced. Specification 738,879 is referred to.ALSO:Finely-divided detergent compositions containing an alkylaryl sulphonate are made less liable to cake by incorporating a minor proportion, e.g. 2-6 per cent, of a water-soluble salt of methyl sulphate.  The components may be mixed and the mixture then finely subdivided, e.g. by spray-drying, or a preformed mixture may be obtained by sulphonating an alkylaryl compound with an excess of sulphuric acid, adding methyl alcohol to form methyl sulphate and neutralizing the mixture, which may then be spray dried.  The compositions may also include other detergents, e.g. a higher alkyl sulphate, or additives such as sodium tripolyphosphate or other alkali-metal phosphate, an alkali-metal silicate or carbonate, carboxymethyl cellulose or a higher fatty alcohol. Comparative experimental results are given of the caking of compositions containing sodium dodecylbenzene sulphonate, with and without sodium methyl sulphate.  The use of potassium and magnesium methyl sulphates is also mentioned.  Specification 738,879, [Group IV (b)], is referred to.

Title: Improvements in or relating to sewing machines
IPC: D05B3/02
Filed: 1936-08-18
Abstract: 468,109. Sewing - machines. UNION SPECIAL MACHINE CO. Aug. 18, 1936, No. 22674. Convention date, Dec. 21, 1935. [Class 112] In a sewing-machine with a laterally vibrating needle in which the needle effects the feed or assists in effecting the feed, the pivot of the needle bar carrier in which the needle reciprocates is between the needle and the carrieroperating means. The needle bar 15 reciprocates in the carrier 30 under the influence of a shaft 35 and links 38, 39, 37, Fig. 3. The carrier is pivoted in a bearing 31 at the base of the sewing head. The needle bar carrier is rocked about its pivot 31 by a rock-shaft 41 and arms 44, 45. The shaft 41 is driven from the main shaft 35 by an eccentric 56 and arm 58, Fig. 1. The amount of rock given to the shaft 41, and carrier 30 is varied by twisting the eccentric 64 relatively to the shaft so as to raise or lower the driving eccentric 56 by the aid of the shoulders 63, the eccentric 56 being loose on the shaft but coupled thereto for driving purposes by a member 62 secured to the shaft and having a key 61 slidingly engaging slots 60 in the eccentric, Fig. 7. For holding the eccentric 65 stationary while the shaft 35 is turned in relation thereto to effect the adjustment, a spring-pressed stop 68 is depressed by its knob 70 to engage the shoulder 67. The adjustment is indicated by the scale 73 on the flywheel hub. The looper shaft 50 is driven by the intermediary of the idle helical gear 54 meshing with equal gears 52, 53. The lower feed roller 20 is given a step-by-step rotation in unison with the needle jogs by an arm 94 adjustably connected to the link 95 on the shaft 96 which is oscillated by the eccentric 77 on the shaft 50. The co-operating presser wheel 18 is pivoted on a bracket 105 on the presser bar and can be thrown up out of action past the hump 114 of a blade spring 110. The feed wheel 20 is adjusted up or down to give proper coaction with the presser wheel by a thumb screw 87 at the end of a screw which enters the tapped lug 88. An arm 86 has a projection 91 which enters notches in the screw 87 to indicate adjustment. Usual four-motion feed dogs may replace the feed wheel.
