Title: System for supporting and/or controlling bodies
IPC: G01C19/38
Filed: 1959-01-23
Abstract: 854,393. Automatic control systems. STANDARD TELEPHONES & CABLES Ltd. Jan. 23, 1959 [Jan. 28, 1958], No. 2564/59. Class 38 (4). Variations in tension in a member coupling two bodies are detected by a rnagnetostrictive detector the output of which compensates for the variations in tension by controlling magnetostrictive means altering the dimensions of the member. In Fig. 3, precession of a gyro 22 rotates a shaft 23 which is supported at each end by adjustable wires 24-31 attached to the shaft tangentially. Changes in tension in these wires are detected by magnetostriction effects which change the inductance of detector coils 40-47. Detector coils, e.g. coils 40 and 42, associated with opposing wires, are connected in series and form part of separate A.C. bridge circuits (not shown), the outputs of which are amplified, rectified and applied to series-connected corrector coils associated with the two wires, e.g. coils 48 and 50 co-operating with permanent magnets 56 and 58. The magnetostrictive effect of these corrector coils 48-55 eliminates tension changes due to small angular movements of shaft 23. To permit larger angular movements of shaft 23 without restraint the detector coils are also suitably connected to a circuit 65 controlling a servomotor 67 which rotates wheels 32, 33 carrying wires 24-31. In a modification, signals from coils 48-55 serving as detector coils, are applied to wide-band amplifiers which energize coils 40-47 serving as corrector coils. In this arrangement the signals correspond to rate of change of tension and an integrating circuit is incorporated in the circuit controlling servomotor 67. An arrangement is also described for permitting movements without restraint of one body relative to another from which it is supported by four adjustable wires each of which has a coil responsive to tension controlling a coil correcting tension utilizing magnetostriction effects. The Specification also refers to an arrangement for maintaining a platform stable in which three gyroscopes mounted as in Fig. 3 are associated with mutually perpendical axes, signals representative of precession of the gyros being obtained either from the detector coils or from devices responsive to light reflected by mirrors carried by the gyros. Signals derived from magnetostriction coils detecting precession of a gyro may also be utilized to control torque applied to the gyro to eliminate such precession.

Patent GB-1122943-A (GB)
Title: Process for the manufacture of linear polyesters
IPC: C08G63/85
Filed: 1966-01-20
Abstract: In the manufacture of linear polyesters by polycondensing (a) an ester of a dicarboxylic acid and an aliphatic diol, other than bis-(b -hydroxyethyl) terephthalate or (b) a mixture of bis-(b -hydroxyethyl) terephthalate with an ester as specified in (a), stannous oxalate is used as the polycondensation catalyst. The glycol ester is preferably obtained by reacting the dimethyl ester of the dicarboxylic acid with the glycol in the presence of zinc acetate, cobaltous acetate, manganous acetate or a mixture of cobaltous acetate and calcium acetate.  Phosphorous acid or triphenyl phosphite may be present during the polycondensation to act as anti-oxidant. Examples disclose the manufacture of polyesters by reacting (1) and (2) dimethyl terephthalate and 1:4-butanediol or 1:6-hexanediol; (3) dimethyl sebacate and ethylene glycol; (4) 1:2-dodecane dicarboxylic acid and ethylene glycol; (5) a mixture of dimethyl isophthalate and dimethyl terephthalate (80/20) and ethylene glycol; (6) dimethyl hexahydroterephthalate and ethylene glycol; (7) dimethyl adipate and ethylene glycol.

Title: Improvements in and relating to apparatus for detecting positional relationship
Inventor: SPENCE WILLIAM
IPC: B65H26/02
Filed: 1958-01-27
Abstract: 886,721. Control of D.C. motors. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 8, 1959 [Jan. 27, 1958], No. 2683/58. Class 38 (3). [Also in Group XXX] In a friction driven winding apparatus, the slip of the hauling cable is detected and compensated for by a magnetic tape device. Thus, the Lilly controller of the winch drum drives a magnetic tape which carries a signal thereon (e.g. a magnetic peak flux). When the winder conveyance stops at a predetermined level, the tape at the same time stops with the signal thereon positioned in front of two stationary magnetic pick-ups A, B, so that normally the windings F 1 , F 2  of amplidyne AM receive equal impulses and the output of the amplidyne being the difference of the sizes of the impulses does not influence motor M. However, if with the conveyance positioned at this level the signal on the tape is out-of-level with the two pickups, due to cable slip, the impulses received by the two windings will be unequal and the amplidyne output will operate motor M. The motor M acting through a differential LB (not shown) will compensatingly adjust the Lilly controller to bring it into correspondence with the position of the conveyance. As shown, the contactors BC, BC<SP>1</SP> are closed when the winder conveyance reaches the said level and the contactors BIS, BIS<SP>1</SP> are closed when the winder brakes are applied and the amplidyne is then operated. This occurs thus only when the conveyance is stationary. The magnetic tape may be replaced by a film coated with a sensitive emulsion so as to operate optically. Specification 2684/58 is referred to.

Title: Improvements in or relating to electrodes for arc welding
IPC: B23K35/02
Filed: 1951-02-02
Abstract: 692,650. Welding by fusion. QUASI-ARC CO., Ltd., and BARBER, B. K. Jan. 18, 1952 [Feb. 2, 1951], No. 2694/51. Class 83 (iv). A composite electrode for arc welding comprises two or more core wires 1 and 2, each covered with a uniform layer of flux material 3 and 4 and wrapping means 5 for binding together the covered cores. The wrapping 5 may be either blue asbestos paper longitudinally disposed around the two cores and of such width that the edges slightly overlap, or tape wrapped helically around the cores, or the wrap - ping may be formed by a woven or braided sheath which fits closely over the cores. The wrapping is fixed to the flux coatings by an adhesive such as a solution of sodium silicate or gum arabic. In an embodiment the wrapping may be indented towards the line of junction of the fluxed core wires as shown in Fig. 4 and the flux coatings 3 and 4 may be joined integrally along their line of contact as shown in Fig. 5. The core wires may be of the same or different material and similarly the layers of flux material covering the component core wires may be of the same or different composition. The flux coating may be applied by extrusion, painting, spraying, or dipping and may be applied simultaneously to all the cores. Alternatively the layer of flux may comprise a wrapping of yarn or paper and the flux layer may be reinforced by a winding of metallic or non-metallic material. When the electrode is to be coiled for use on an automatic welding machine a bundle of metal strands may be used for each core wire to give enhanced flexibility.

Title: Improvements in the thawing of frozen fish
IPC: A23B4/07
Filed: 1961-01-24
Abstract: Frozen blocks of edible animal matter, particularly fat-free fish such as cod, are thawed without "run-away heating" by exposing each block repeatedly (at least twice) to irradiation by an R.F. field the strength of which, on each occasion is pre-determined to give an optimum value of the mean rate of energy input per unit mass of the edible matter, the field strength being also pre-determined, at least in part, on the basis of the state of the block at the initial instant of irradiation by the field and of the frequency of the field.  Each block, glazed or packed in ice, may be passed at a uniform rate through a succession of separate R.F. fields, temperature inequalities in the block being caused to equalize by internal heat conduction between exposure to successive R.F. fields. The experimental procedure is described; in the examples radio frequency fields of 36-40 mc/s. are employed.  The invention is regarded as a development of the method described and claimed in Specification 928,452.

Title: Improvements in or relating to method of treating latex and products thereof
IPC: C08C1/08
Filed: 1927-01-31
Abstract: 268,299. Naugatuck Chemical Co., (Assignees of McGavack, J.). March 24, 1926, [Convention date]. Latex, treating.-A concentrated latex having low viscosity is produced by adding an unhydrolized creaming agent to latex, removing the layer of thickened latex from the serum, and subjecting it to a hydrolizing action. Suitable creaming agents are vegetable colloids such as pectin, Irish moss, or karaya gum, which are dissolved in cold water, and are added to the latex in the proportion of 0.4-0.7 or more parts of the colloid to 100 parts of rubber. The latex separates into a layer containing practically all the rubber at a concentration of about 50-55 per cent solids, and a serum layer, in 30-50 hours. The creamed latex has a high viscosity which is reduced by hydrolizing, for example, by heating to a temperature below the boiling point of water, say 80‹ C. for two hours. Stabilizing agents, such as saponin or soaps, are preferably added to the creamed latex before heating.

Abstract: 361,719. Disintegrating material by rasping. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Payne, J. H. ; 79, West Street, Ballston Spa, New York, U.S.A.) Jan. 28, 1931, No. 2786. Convention date, Jan. 28, 1930. [Class 59.] When the pressure of logs 16 on a grindstone 10 is excessive, springs 14, 15 are compressed to reduce the resistance of a carbon pile 45, and affect the circuit of a Wheatstone bridge formed by resistances 43 .. 46, so that the potential of the grid 32 of a discharge device 30 is changed. The output from the device 30 changes accordingly, to readjust the field 40 of a generator 27 which supplies a motor 22 feeding the logs 16, to bring about a reduction in the rate of feed. Similarly when the pressure on the grindstone falls below a predetermined value, the rate of feed is correspondingly increased. The predetermined pressure may be adjusted by varying the ratio between the resistances 43, 44.

Patent GB-638769-A (GB)
Title: Improvements in or relating to the process for production of carbon monoxide
IPC: C01B32/40
Filed: 1948-01-30
Abstract: Carbon monoxide is made by reducing a metal oxide, e.g. iron oxide, by a gas-containing carbon monoxide and/or hydrogen to a lower stage of oxidation or to the metal, re-oxidising the thus reduced metal oxide with carbon dioxide to yield a mixture of carbon monoxide and carbon dioxide, and removing the latter therefrom.  In a preferred embodiment, a reducing gas, which may be preheated at 21, <PICT:0638769/III/1> is passed through pipe 8, and a heated oxide bed 6 and burned in air and/or oxygen admitted through pipe 10, the resulting gases heat up a superheater 7 and exit through pipe 12, a waste heat boiler 20, which may be byepassed, and the preheater 21 to the atmosphere with or without prior removal of carbon dioxide.  The apparatus is then purged by passing carbon dioxide from pipe 18 downwardly through 7 and 6 and out through pipe 14, after which valve 15 is closed and the gases, viz. a mixture of carbon monoxide and carbon dioxide, leave through pipe 16 for subsequent cooling and removal of carbon dioxide.  In modifications, the carbon dioxide may be dried before use, preheated or passed in the same direction as the reducing gas, which may be water gas, producer gas, blast furnace gas, distillation gas (coke-oven gas &c.) or industrial hydrogen. The steam from the waste heat boilers may be used for purging the apparatus or for the carbon dioxide recovery process.  The carbon dioxide recovered from the spent gases and the carbon monoxide-dioxide mixture may be reused in the process, and the gas, mainly nitrogen, remaining after carbon-dioxide removal from the spent gases may be used as an inert gas or as raw nitrogen.  The superheater 7 may be separated from the vessel containing the oxide bed 6 or it may be integral with it, e.g. as an annular space around the bed or the bed may be in an annular space round the superheater.

Abstract: 584,910. Cathode materials and processing. M O VALVE CO., Ltd., GAIT, A. W. W., and TAPPING, C. W. March 6, 1942, Nos. 2968 and 9518. [Class 39) (i)] In the manufacture of an activated indirectly heated cathode, a metal cylinder whose diameter is less than that of the final cathode is coated with activating material so thickly that the diameter of the coated cylinder-is greater than. that of the final cathode, and the coated cylinder is then passed through a die to reduce its diameter to that of the final cathode. The coated cylinder may be carried on one of two pins 6, 7, one of which protrudes through a die 9 and the other extends from a plunger 5 movable by crank arm 10. As the plunger approaches the die, the pins first come into contact, thus supporting the cathode, and pin 6 is then pressed back through the die against the pressure of spring 8. The excess activating material is thus scraped off. The throw of arm 10 may be adjusted for cathodes of different lengths. In a modification, the plunger 5 is hand operated and carried on two pillars, and pin 6 is omitted ; the apparatus can be inverted so that excess material falls away from the die. The activating material may comprise barium and strontium carbonates, ball-milled for 16 hours with butyl acetate, methyl alcohol, ethyl oxalate and nitrocellulose; specific proportions are given in an example. Dimensions of cathode and coating are also given.
