Abstract: 1,089,223. Monitoring radio links. SOCIETA' ITALIANA TELECOMUNICAZIONI. March 9, 1966 [March 12, 1965], No. 10294/66. Heading H4L. A radio receiving station which comprises two receivers normally working in parallel is provided with a logic circuit responsive to signals P1, P2 from the respective receivers which occur when a pilot tone level falls below a predetermined value, and signals R1, R2 occurring when the noise level in the respective receivers increases above a predetermined level. The arrangement is such that an alarm signal is given at the receiver and also transmitted back to the transmitter via an auxiliary radio link when P1 occurs with P2 or R2, or R1 occurs with P2 or R2 this indicating the possibility of a fault at the transmitter. However, when only P1 or R1 occurs the first receiver is switched out of circuit and when only P2 or R2 occurs the second receiver is disconnected.

Filed: 1940-06-15
Abstract: 539,089. Vitamin concentrates. DISTILLATION PRODUCTS, Inc. June 15, 1940, No. 10417. Convention date, Oct. 14, 1939. [Class 2 (iii)] [Also in Group III] Oil is extracted from fish tissue by means of a low vapour pressure solvent (that is a solvent having a boiling-point above 78‹C. at 1 mm. pressure) which may be a natural vegetable or animal oil, containing anti-oxidant, or a fish oil residue from which the vitamin fraction has been distilled off, or a hydrocarbon oil. The solvent may be distilled off from the extract under high vacuum, leaving the fish oil containing vitamins and anti-oxidant. If desired the extractant oils may contain other vitamins so that the final product when a vitamin concentrate is desired, may contain vitamins A and E, E and K, or A, D, E and K ; the last-named being obtained from halibut or tuna liver by extraction with a mixture of soya and wheatgerm oils and subsequent high vacuum distillation. In examples (1) ski-jack livers after treatment with alkali in a known manner are extracted with soya oil from which 10 per cent. of its weight has been removed by high vacuum distillation ; (2) soup-fin shark livers are treated as in example (1) but with sardine oil residue mixed with crude corn oil as solvent; (3) halibut livers are extracted with sesame oil, a vitamin A concentrate being if desired separated from the extract by high-vacuum distillation ; (4) blue-fin tuna livers are extracted with a petroleum fraction boiling at 100-200‹C. at 0.1 mm. pressure mixed with crude corn oil, the extract being distilled in a high-vacuum still to remove the solvent mineral oil, and if desired the residual oil is again distilled to separate a vitamin A and D concentrate.

Title: Improvements in electro-dynamic power transmitting apparatus
IPC: B63H23/24
Filed: 1941-08-18
Abstract: 548,588. Transmitting mechanical power. BRITISH THOMSON-HOUSTON CO., Ltd., and JEWITT, D. E. Aug. 18, 1941, No. 10490. [Class 38 (iv)] Where two or more prime movers drive a common load, each through an electrodynamic coupling consisting of a field structure associated with an armature, the relationship between the number of poles of one coupling and that on the other or others is such that the load can be driven at a reduced speed by one or more prime movers running at normal speed, the slip energy of the driven couplings being supplied to the load through the couplings of the idle prime mover or prime movers. A slip propulsion system may comprise internal combustion engines or turbines 1, 2 each driving, through a coupling 3, 4 comprising a field structure 7, 8, a polyphase armature 9, 10 and a pole face squirrel cage winding, a common reduction gear 5 and propeller shaft 6. To obtain efficient operation at 80 per cent. propeller speed and the prime mover 2 held stationary the coupling 3 has four times the number of poles of coupling 4. A similar arrangement may be applied to a twin screw drive. A modification is described for a triple screw-drive with three pairs of prime movers, each pair normally driving one screw and wherein, for example, the outer pairs of prime movers may be stopped and their screws driven respectively through their electrodynamic couplings which are supplied in parallel each from one of the couplings of the centre pair.

Title: Improvements in or relating to knitted articles and to methods of knitting
IPC: D04B1/06
Filed: 1931-04-09
Abstract: 376,350. Knitting. WILDT, E., HOLMES, H. H., and WILDT & CO., Ltd., Adelaide Works, Leicester. April 9, 1931, Nos. 10548 and 15005. Drawings to Specification. [Class 74 (ii).] Hosiery knitted fabric having non-laddering properties is produced from ground and warp loops knitted together or interlocked, the latter lying on the rear face of the fabric. The warp loops may, in places, appear on the front face of the fabric or be absent altogether from some wales. Generally, the ratio of the diameters of the ground and warp yarns is 1À4 to 1 or over. In a preferred method of carrying the invention into effect the warp yarns are made to appear on the rear face by adjusting their tensions relatively to the ground yarn. In a method illustrated by drawings, each warp yarn is first wrapped round its needle and subsequently the ground yarn is laid on the needles, but this order may be reversed. Specifications 313,657, 327,958, 327,987, 327,988, 328,026, 331,930, [all in Class 74 (ii), Knitting &c.], 347,307, and 364,108 are referred to.

Title: Improvements in or relating to take-down mechanism
IPC: D04B15/88
Filed: 1936-09-17
Abstract: 479,080. Knitting - machines ; looms. RAVEN, R. F., and RAYNOR, H. A. Sept. 17, 1936, No. 10655/37. Divided out of 467,659. [Class 74 (ii)] [Also in Group IX] Relates to take-down mechanism suitable for use in circular machines for knitting small diameter tubular elastic fabrics and in other machines such as looms. Two or more pairs 52, 52a of take-down rollers are rotated by ratchet wheels 53, 54 respectively. Pivoted on the spindles carrying the ratchets are two rockers 56, 56a, each carrying, at one end, a roller or its equivalent 57 and being connected at its other end to a tension spring 58 anchored to a relatively stationary part. Each rocker carries a pivoted pawl 59, coacting with ratchets 53, 54. The rollers 57 are caused, by the rotation about a vertical axis of the takedown mechanism to traverse the inclined or suitably shaped underface of a ring or race 60, thus lowering the pawls 59 one or more teeth on the ratchets. If the tension in the fabric passing between a pair of rollers becomes great enough, it will cause thespring 58 to remain tensioned and that pair of rollers will not be rotated until this tension is lessened. In a modification, Fig. 5, the cam ring is divided into semicircular portions 60a, 60b, pivoted at 61, and oppositely inclined to give two racks per revolution to the take-down mechanism. The inclination of each half-ring is adjustable by means of a trunnion nut 64 and spindle 63 provided with a knob 65 and indicator 66. Alternatively, both halves may be simultaneously adjustable by means of toggle links connected to a common nut mounted on a spindle adjacent the axis 61. For insertion of the fabric, the roller may be moved apart by means of a lever 71, and mechanism similar to that described in Specification 357,323, means 72 may be provided to adjust the gap between the take-down rollers according to the grip desired or the fabric thickness. The rollers 57 engage the upper surface of the cam ring 60. A second pawl 73 associated with each ratchet wheel is operated by a spring 74 to prevent reverse rotation of the take-down rollers. Specification 467,659 also is referred to.

Title: Improvements in stiffeners for boots and shoes
IPC: A43B23/08
Filed: 1924-05-01
Abstract: 235,353. Macdonald, D. B. May 1, 1924. Stiffeners. - Counter and toe stiffeners of the flat type treated w i t h a stiffening medium and afterwards conformed to shape with an upper on a last are provided with slits or cuts at one or more places to facilitate the shaping of the stiffener to the curvature of the last. A counter stiffener 1, Fig. 1, may be slit centrally at 2 vertically from its upper edge, so that the edges of the parts may overlap and allow the stiffener to conform to the last. The slit may however be made from the lower edge 4 upwards, or the stiffener may be slit on both edges. In a modification, Fig. 3, an opening 5 may be made in the centre of the stiffener and a small layer 6 placed under it to cover the opening. Where the stiffener is composed of several layers, an opening may be made in each of the outer layers and the intermediate layers may have an opening cut or merely slit. The bottom edge of the stiffener may have V-shaped or other suitable notches or gaps formed therein in known manner.
Patent GB-650223-A (GB)
Title: Production of magnesia
IPC: C01F5/06
Filed: 1948-04-19
Abstract: Periclase crystals are obtained from impure magnesian materials such as dolomite, magnesite, brucite, calcite, serpentine, or olivine by firing the material with the inclusion of lime at a temperature above 2800 DEG  F., to combine the impurities as calcium compounds which are separated by physical and/or chemical means such as classification, washing, froth flotation or magnetic separation followed by treatment with sulphuric acid to remove the residual calcium oxide, without affecting the periclase formed. Dolomite may be fired alone at 3000 DEG  F. to form periclase crystals of 5 microns size or a small amount of iron oxide may be added forming both dicalcium ferrite which acts as a flux and magnesium ferrite which is absorbed in the periclase, thus facilitating magnetic separation.  Alternatively boron compounds, fluorite, topaz or cryolite are added as fluxes and a temperature of 3200 DEG  F. employed.  If silica is present in the starting material, sufficient lime is added to form calcium compounds of the impurities, and the silica into dicalcium silicate; a temperature above 3450 DEG  F. is employed and the dicalcium silicate spontaneously dusts on cooling when it inverts from the a  or b  to the g  form, thus, with or without a light grinding, freeing the crystalline periclase.  Further cleansing of the periclase by physical and chemical means may follow.

Title: Improvements relating to governing means for internal combustion prime movers
IPC: F02D1/00
Filed: 1944-06-05
Abstract: 580,149. Regulating. LUCAS, Ltd., J., HOOKER, S. G., WATSON, E. A., and IFIELD, R. J. June 5, 1944, No. 10792. [Class 7 (vi)] Fuel supply is governed by the speed of the compressor and absolute temperature of the air entering the compressor in accordance with expression N=C #T, N being the rate of rotation of the compressor, T the absolute temperature and C a constant. The compressor is driven by the engine which also drives a rotary member a, Fig. 1, carrying spring pressed plungers d engaging a fixed swash-plate e which reciprocates them to draw fuel from an inlet h, i and deliver it through an outlet j, k. To vary the quantity of fuel delivered, the inclination of the swashplate e is adjusted by a piston q connected thereto by a rod s, the piston sliding in a cylinder p open at one end to the delivery pressure of the pump through a passage t and at the other end to the same pressure as modified by a restricted orifice in a passage u. A vent v in the end of the cylinder is normally closed by a lever wand the piston is at rest. Should the speed become excessive, the pressure of fuel, delivered from radial passages o in the rotary member a and communicating by an axial passage m with the fuel inlet passage i, displaces a diaphragm 2 forming one wall of a chamber 4 communicating by a passage 5 with the chamber housing the rotary member a and the diaphragm rocks the lever w, against the pressure of a spring y, opening the vent v. The piston q then moves to the right reducing the fuel supply until reduced speed lowers the pressure in the chamber 4 and the spring y rocks the lever w to close the vent v. The pressure resisting the movement of the diaphragm 2 is modified by a thermo-sensitive element 10 connected to the diaphragm by a rod 11. The ratio of the inlet and outlet pressures of the compressor may be substituted for the direct thermal control. The vent v<1>, Fig. 2, of the cylinder p<1> is controlled by a lever w<1> rocked by a diaphragm 24 the sides of which are exposed respectively to the inlet and outlet pressures of the compressor 13. The diaphragm operates against the action of a spring 20 engaging the end of a second lever 19 having an adjustable contact 22 with the lever x' and the power of the spring is modified by the pressure of an evacuated capsule 21 engaging the opposite end of the lever 19. In another modification, a thermo-sensitive element 35, Fig. 3 acts directly against a rod 33 closing the outlet 17<2> from the vent v<2> of the cylinder p<2>. The rod 33 carries a piston 30 opposite sides of which are exposed fto the fuel pressures in front and behind an orifice 37 in the fuel supply line 38 from the pump and the size of the orifice is adjusted by a tapered plunger 39 actuated by an evacuated capsule 41 exposed to atmospheric pressure. Alternatively, the rod 33 may be associated with capsule and the thermal element determine the size of the orifice 37.

Title: Process for the purification of polymerizable heterocyclic nitrogen compounds
Inventor: MARWIL STANLEY JACKSON
IPC: C07D213/06
Filed: 1958-04-03
Abstract: Polymerisable heterocyclic compounds containing carbon and nitrogen only in the heterocyclic nucleus and having unsaturated hydrocarbon side chains when mixed with the corresponding saturated compounds are separated and purified by fractionating the mixture so as to concentrate the polymerisable compounds, subjecting the resulting concentrate to fractional crystallisation, recovering the molten polymerisable compound and polymer and separating the polymer from the polymerisable compound by known methods such as heating in propane to precipitate the polymer, fractional distillation or steam distillation.  The process may be used for the separation of 2-methyl-5-vinylpyridine from a mixture containing 2-methyl-5-ethylpyridine and also for the separation of other alkene, alkadiene or alkyne substituted heterocyclic nitrogen compounds such as pyridines, quinolines, isoquinolines, piperidines, pyrroles, pyrrolidines or pyrrolidones, when mixed with the corresponding saturated compounds.  Polymer formation can be partly inhibited in the fractionation step by the addition of an inhibitor such as sulphur, ditertiary butyl catechol or ditertiary butyl polysulphide. Specifications 734,754 and 734,756 are referred to.
