Title: Improvements in or relating to processes for the protection of articles consisting of ferromagnetic material
IPC: H01F1/18
Filed: 1956-08-02
Abstract: 803,566. Transformers and inductors. VACUUMSCHMELZE A.G. Aug. 2, 1956 [Aug. 2, 1955], No. 23914/56. Class 38 (2). [Also in Groups XV and XXXVI] Coiled or laminated ferromagnetic material is protected by applying thereto a layer of mica by electrophoresis, this term meaning the migration under the influence of an electric field of particles suspended in a fluid, e.g. gas, vapour or liquid. Specifically, mica particles of size 1 to 20 microns, are dispersed in distilled water and a magnetic core comprising a coil of ferrous alloy strip 10 mm. wide and 0.05 mm. thick and containing 50 per cent nickel is made an electrode in a vessel containing the dispersion and forming the other electrode. A voltage of 60 at 0.5 amp. is applied for half a minute to deposit a layer of mica 1 mm. thick on the core. If desired, after drying, the core is dipped in varnish to provide a hard outer shell, the inner layer of mica remaining soft. A plurality of mica layers may be applied, the particle size differing from layer to layer and instead of varnish a synthetic resin may be applied to the core, e.g. by dipping, spraying, brushing or casting. The dispersion may include bonding agents, e.g. 10 to 20 per cent by weight silicoresin or water glass.

Title: A composite sheet material
Inventor: SMITH HILBRE HENRY
IPC: B32B15/08
Filed: 1963-06-15
Abstract: 1,028,630. Laminates and laminating. COTTON SILK & MAN-MADE FIBRES RESEARCH ASSOCIATION. June 15, 1964 [June 15, 1963; Oct. 30, 1963], Nos. 23920/63 and 42757/63. Heading B5N. A heat-reflective fabric, comprising a basic fabric having applied thereto an aluminium or other metal foil made porous by rupturing in the interstices of the fabric as by pressure by a resilient surface, has applied on at least one side of the fabric a resilient material having a bulk density less than the density of the material from which it is formed such as a porous or non-porous foamed material, typical materials being polyester foam with interconnected cells, and polyurethane or rubber foam. An additional layer of fabric may be applied to the remote side of the resilient material. To make the material a web of metal foil roller-coated with adhesive may be laminated to a viscose or other fabric between a hard roller and a rubber-covered roller (applied to the free surface of the foil to press it into the fabric and produce apertures by rupturing), and the composite web so formed may be coated with adhesive on the fabric side and laminated to a foam web between a further pair of rollers. Alternatively, Fig. 3, the foil web 11, coated with adhesive at 63, may be laminated to the fabric web 10 between hard rollers 50, 51, by the intervention of the web 12 of foam material which is then separated from the laminate by a roller 54 transferred to the reverse side of the laminate by rollers 55, 58, and bonded the underside of the laminate (coated with adhesive at 64), between rollers 52, 53. In a further modification a preformed combined web of fabric and resilient material, fed between rollers, is carried back to enter the nip of the rollers again in the same direction, an adhesivecoated metal foil being fed into the nip between the two laminate layers, the resilient layer of the first part of the laminate web thus being used as the resilient material to laminate the foil to the fabric layer at the same time rupturing it by pressure. The fabric layer may be of knitted or other material and a backing fabric of the resilient material may be provided.

Title: Process for separating carbonate compounds from the alkaline electrolytes of fuel cells
IPC: H01M8/06
Filed: 1969-05-12
Abstract: 1,213,777. Separating carbonates from hydroxides. VARTA A.G. 12 May, 1969 [14 May, 1968], No. 24152/69. Heading C1A. [Also in Division H1] Potassium and/or sodium carbonates may be separated from the alkaline electrolytes of fuel cells by passing the carbonate containing electrolyte over solid potassium and/or sodium metal hydroxide. It is preferred that a storage vessel containing the solid hydroxide be connected to an electrolyte circuit when the carbonate level in the electrolyte reaches for example 2 moles of carbonate per 4 moles of hydroxide. The carbonate free hydroxide leaving the storage vessel is preferably mixed with fresh fuel (e.g. methanol) and water and returned to the electrolyte circuit. Oxygen is fed to the fuel cell along with electrolyte either in the form of air or derived from the decomposition of H 2 O 2  wherein the resulting water may be used to dilute the carbonate free hydroxide.

Title: Methods of and apparatus for reproducing pictures
IPC: H04N1/405
Filed: 1971-04-19
Abstract: 1355540 Facsimile apparatus DR-ING RUDOLF HELL GmbH 19 April 1971 [18 March 1970] 24271/71 Heading H4F  Relates to reproducing an original, which has been scanned orthogonally, with a half tone (screened) pattern that is rotated relative to the direction of scanning. For colour originals a plurality of half tone separations are produced with their half tone patterns rotated through different angles. The original is effectively covered with one or more raster networks, the meshes and angles of inclination of which are so dimensioned that large meshes having a congruent network structure and orthogonally oriented with respect to the scanning direction are obtained which are called "parcels". Two such parcels 5, 6, 7, 8 and 6, 7, 9, 10 are shown in Fig. 1 the half tone pattern network lines 1 and 2 of one raster network being shown. Each parcel is divided into sub-areas Ia . . . IIIc as shown in Fig. 3c, the parcel being scanned in three vertical lines (one scan indicated at 27) and the appropriate information for reproducing such a half-tone dot pattern, e.g. for a constant tone as shown in Fig. 3c, is stored in a core store, and is read out when a tone corresponding to that constant tone is scanned in the original. Reproduction of each sub-area is effected by an on-off modulated light spot from a line scanned C.R.T. (the original and light sensitive paper being disposed on longitudinally stepped, rotating drums) each sub-area being scanned in a plurality of lines, e.g. 1-8, Fig. 6, each line comprising 12 elemental areas (30 represents the C.R.T. light spot). The core store is initially loaded with information for reproducing the subareas of each parcel for each of a plurality of tonal values for each half-tone pattern inclination. Input and output registers are associated with the store which in response to a scanned tonal value in the original which is binary coded, cause the appropriate parcel of information to be selected and the appropriate sub-areas therein to be reproduced in the correct sequence. Due to the symmetrical nature of many of the sub-areas for each tonal value for each raster inclination the information for a subarea may be read-out for reproduction as stored or inverted thus reducing the amount of information it is necessary to store. The video signal from the original may be stored on magnetic tape and by altering the drum diameters scale changes may be produced. Half-tone raster networks at 45 degrees, arc tan <SP>1</SP>/ 3  and arc tan <SP>2</SP>/ 3  are described the reproduced dots being square (as shown), circles, elipses, triangles or rectangles. The sub-areas of the raster networks may be square (as shown), rectangles, triangles, rhombi or hexagons. Reference has been directed by the Comptroller to Specification 1,234,975.

Title: Improvements in or relating to sliding-clasp fasteners
IPC: A44B19/38
Filed: 1931-08-28
Abstract: 370,316. Sliding-clasp fasteners. RAYMOND, A. F., 113, Cours Berriat, Grenoble, Isere, France. Aug. 28, 1931, No. 24289. Convention date, Aug. 28, 1930. [Class 44.] In a sliding-clasp fastener in which the stringers a, b carrying the usual fastener members a', b<1> may be completely separated, the end of one stringer b carries a housing d in which is a sliding sheath e normally urged outwards by a spring f. A stop member c on stringer a is normally housed in the sheath e and housing d as shown. To effect the normal disengagement of members a<1>, b<1> the slider is moved into abutment with the end of sheath e, the spring f retaining sheath and slider in the position shown, with the terminal members a<1>, b<1> still in engagement. To effect separation of the stringers, the lower end of the slider is pressed into the housing d against the action of spring f, thus disengaging the terminal members a<1>, b<1> and allowing stringer a to be withdrawn in the direction of arrow F.

Title: Improvements in and relating to methods of obtaining vacuum tightness in x-ray tubes
IPC: H01J35/12
Filed: 1952-09-29
Abstract: 715,669. X-ray tubes. GENERAL ELECTRIC CO. Sept. 29, 1952 [Sept. 28, 1951], No. 24343/52. Class 39(1) [Also in Group XXII] In an X-ray tube anode in which the anode body 21 has a thin-walled portion 21<SP>1</SP> separating a cooling chamber 23 from the target button 22, the wall 21<SP>1</SP> has embedded within it a cup-shaped insert of dense material such as molybdenum. This enables the wall 21<SP>1</SP> of the anode body, which is of cast metal such as copper, to be made thinner than otherwise; the total thickness of target, copper wall, and molybdenum in the example described is # inch or less, the target button accounting for <SP>1</SP>/ 16  inch of this. Figs. 3 and 5 (not shown) illustrate different arrangements of baffles for directing the flow of fluid in the cooling chamber. In the modified arrangement of Fig. 7 (not shown), the electrons impinge normally on the target, and a method of manufacturing this form is shown in Fig. 6. The tungsten target button 22 is placed flat on a graphite plate 49, and anchored in position by pins 50 fitting into holes 51 in the plate. Above this is placed the insert 25, similarly anchored by pins 52 fitting into holes 53. Insert 25 is thus spaced from target 22 by the thickness of the horizontal bent portions of pins 50. The main anode body of copper is now cast over this structure, preferably under vacuum, so that copper flows between the target and the insert 25, thus embedding the latter; the graphite plate 49 is then removed, leaving the completed anode. The form shown in Fig. 2, with a cup-shaped insert, may be made by a similar method.

Title: Process for the purification of silicon halides and halogenosilanes
IPC: C01B33/08
Filed: 1959-07-15
Abstract: A silicon halide or halogenosilane is purified, for use in the preparation of silicon, by contact in the vapour or liquid form, before or after fractional distillation or sublimation, with brown amorphous silicon, activated graphite, or highly activated silicic acid, or a mixture thereof, at from the boiling point of liquid air to 300 DEG C.  The graphite is activated by oxidation with air at red heat, and the highly activated silicic acid is obtained by hydrolysis of silicon chloroform with water.  As a modification, the amorphous brown silicon may be partially oxidised, e.g. by air at elevated temperature.  The contact materials may be deposited on carriers, e.g. quartz glass, or other glass, or other inert materials.  Contact may be effected at atmospheric pressure to 10 atmospheres.  Examples refer to the purification of silicon chloroform, silicon tetrachloride, and silicon tetrabromide, after distillation.

Abstract: 1353247 Electromagnetic couplings STANDARD MAGNET AG 19 April 1971 [17 March 1970] 24415/71 Heading H2A [Also in Division F1] A pump embodying a dynamo-electric coupling to isolate the drive shaft 5 from the chamber through which the pump fluid is circulated comprises a driving member 7 of the coupling mounted on the shaft 5 and located radially inside a part-spherical non-magnetic boundary wall 8 of the chamber and a driven member 10 of the coupling carrying the impeller blades 13 and located radially outside the wall. The driving member 7 comprises a part-spherical shell formed of a number of segments of magnetic material permanently magnetized in the radial direction (Fig. 4, not shown) and the driven member 10 comprises a part-spherical magnetic ring carrying a squirrel cage with skewed bars (Fig. 3, not shown). The second member is supported from a disc 14 carried by a spherical ball 16 mounted between bearings 15, 15<SP>1</SP>. The pump may be the cooling water pump of a combustion engine, the drive shaft 5 being rotated by a pulley wheel 6. In a modification, (Fig. 5, not shown) the driving member (50), or a magnetic yoke thereof, is not mounted directly on the shaft 5 but is carried by a bellows (51) coupled via a capilliary tube with a fluid-containing tank (53), so that thermal expansion of the fluid will move the driving member closer to the boundary wall 8. This reduces the air gap between the two members, thus decreasing the slip and increasing the pumping rate when the cooling fluid being pumped gets too hot. Reference has been directed by the Comptroller to Specification 1,287,145.

Abstract: 633,671. Electromagnetic relays. GENERAL RAILWAY SIGNAL CO. Sept. 10, 1947, No. 24865. Convention date, Sept. 17, 1946. [Class 38 (v)] The two laterally-spaced cores 15, 16 are connected at the R.H. end by a magnetic yoke 17 and near the R.H. end by two permanent magnets PM1 and PM2 and are adapted to attract or release an armature 24 against a spring bias according to the direction of current in the series-connected windings 34, 35. After attraction, the armature remains in its attracted position when the windings are de-energized. The flux from the permanent magnets has two paths, one through the armature and the other through the yoke 17 which it normally saturates, the former being normally insufficient to attract the armature from its released position. A comparatively small current causes attraction of the armature since the flux due to such current while assisting the permanent flux through the armature readily passes through the yoke 17 where it opposes the permanent flux. At release, a considerably greater current than that necessary to effect the release will not cause reattraction of the armature owing to the high reluctance of the saturated yoke 17 where the permanent and electromagnetic fluxes are now in the same direction. The arrangement may be designed so that the " pick up " and " knock down values of the forward and reverse currents are equal.
