IPC: F23D14/62
Filed: 1970-02-11
Abstract: 1303266 Gas burner H MAILE and H WOBBERMIN 11 Feb 1970 [11 Feb 1969 28 Feb 1969] 6478/70 Heading F4T In an atmospheric gas burner (Fig. 1), an air supply passage 10 contains a gas supply chamber 12 which has a gas outlet aperture 15 defined by an end 121 of the gas supply chamber and a plane surface 141 which communicates with a conical surface by way of a curved annular surface 142, whereby gas from aperture 15 flows, by the Coanda effect, over the surface 142 and the conical surface and induces air flow through the air supply passage 10. The aperture 15 is adjustable.  In another embodiment (Fig. 2), the gas supply chamber 22 is in the form of an annular jacket and gas leaves this chamber via an annular space 25 and flows as a boundary layer over a surface 241 drawing air in at the intake region 13 and mixing with it within a region defined by a Venturi-shaped wall 24. In modifications (Figs. 3 and 4, not shown), annular Venturi-shaped secondary air inlets are provided downstream of the burner bodies 10 and 20. In place of Venturi-shaped inlets, Laval jets may be used to supply secondary air, the amount of which may be controlled. The burner may be controlled by a thermostat or pressure regulator.

Abstract: 340,859. Inductances ; insulators. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13A, Emmasingel, Eindhoven, Holland. Feb. 27, 1930, No. 6585. Convention date, Mar. 2, 1929. [Classes 36 and 37.] An inductance coil is screened by enclosing it in a one-piece metal case, the walls of which are then deformed to adjust the value of the inductance. The coil 2 may be suspended by straps 14 in a metal case 1 with spherical ends. The coil is connected to a measuring circuit and the case placed between the jaws of a vice, which are closed until the inductance attains the desired value. The case may be exhausted or filled with dry air and hermetically sealed. In such a case the lead 17, Fig. 2, may leave the case through an insulating sleeve 15 which opens into a metal cup 16 filled with cement. The ends of the case may be doublewalled. The case may consist of insulating material with conducting lining instead of metal. A switch may be mounted on the case. The Specification as open to inspection under Sect. 91 (3) (a) states that the inductances may be adjusted by moving the coil or a piece of metal within the case. This subject-matter does not appear in the Specification as accepted.

Title: Laminated magnetic recording tape
IPC: G11B5/84
Filed: 1965-02-16
Abstract: 1,039,648. Magnetic structures. GENERAL ELECTRIC CO. Feb. 16, 1965 [March 20, 1964], No. 6697/65. Heading H1H. [Also in Division B5] A laminated magnetic recording tape comprises a polycarbonate supporting lamina which is in direct contact with a magnetic lamina comprising magnetic particles in polycarbonate binder. Suitable polycarbonate resins are aliphatic, aromatic or heterocyclic compounds and may include plasticizers, stabilizers, fillers, curing agents, dyes and pigments. Suitable solvents are alkyl halides, e.g. methylene chloride and ethylene chloride. Suitable magnetic materials are iron, metal alloys, #Fe 2 O 3  and Fe 3 O 4 . The magnetic lamina is prepared by forming a dispersion of the magnetic particles in a solution of the carbonate binder in a solids/solvent ratio of 20: 80 by weight. This dispersion is applied by doctor blade to a temporary support having a smooth surface, e.g. a belt of polyethylene terephthalate, stainless steel or aluminium. The magnetic material is oriented and dried by air, oven, blower, or radiant heater to give a layer 0À0004 inch thick. The supporting lamina may be based on a glass fabric reinforcement which may be woven or unwoven and of which details are given. If this fabric has a starch oil sizing this latter may be removed by heating. Thereafter the fabric is optionally subjected to a priming coating of an elastomer such as ethylene propylene rubber, polyisobutylene, polycarbonate elastomer, silicone fluid, polyethylene-vinyl acetate copolymer and nitrile silicone. The fabric is then impregnated with the polycarbonate which has a M.W. between 15,000 and 20,000, using knife edges to control thickness. The fabric is dried either wholly in a vacuum, or partly in air followed by heating in an oven at 130‹ C. for 1 hour. The dried tape is then subjected to a heat-pressure treatment-for example by calendering-to give smooth even surfaces. Alternatively these surfaces are formed by laminating polycarbonate films on either side of the glassreinforced tape. Continuous processes may be utilized. The supporting lamina is united with the magnetic lamina by heat and pressure and a uniform surface is provided. A further supported lamina containing silica as filler instead of magnetic particles may be applied tothe base layer on the opposite side from the magnetic layer. In this case the base layer need not be glass-reinforced.

Title: Improvements in or relating to control arrangements comprising a saturable inductance for thermionic valves and other circuits
IPC: G05F1/00
Filed: 1940-04-15
Abstract: 537,801. Valve generating circuits ; radio receivers. PHILIPS LAMPS, Ltd. April 15, 1940, No. 6809. Convention date, April 17, 1939. [Class 40 (v)] [Also in Group XXXV] An inductance has an iron core which is variably saturated by a winding carrying alternating current and variable amplitude. The value of the inductance depends upon the average slope of the magnetization produced by the A.C. and hence increases with increasing amplitude thereof. The frequency of the output of a back coupled discharge tube 7 is controlled by feeding a high harmonic thereof derived from a multivibrator 8 into a circuit comprising the saturating windings 4a, 4b of an inductance 2a, 2b fed with a synchronizing oscillation of the same frequency supplied to a transformer 12 from a generator at the other end of a transmission line. Any frequency drift is corrected by the change in the inductance of the windings 2a, 2b in the timed grid circuit arising from want of synchronism. The control synchronizing oscillation alone may be fed to the saturating windings 4a, 4b. Constant voltage for supplying an oscillator 7 and multivibrator 8, Fig. 6, from a variable voltage source 14, 15 may be obtained by a grid controlled tube 17 varying the current in a resistance 16 in the supply circuit in accordance with changes in the high frequency output a part of which is fed into saturating windings 4a, 46 to form inductance 2a, 2b in a circuit 20 tuned to a frequency slightly different from that of the oscillator 7. The rectified voltage appearing across this circuit is fed to the grid of the tube 17. Remote tuning of the oscillatory circuit 24 of a radio receiver may be obtained by an inductance 2a, 2b, Fig. 7 saturated according to the output of an oscillation generator 26 controlled by a resistance 27. Any change due to variation of the supply voltage 30, 31 is annulled by a second inductance 2a<SP>1</SP>, 2b<SP>1</SP> saturated by windings fed from the D.C. source and consequently varying oppositely from the A.C. saturated windings.

Abstract: 1454357 Data processing system SIEMENS AG 15 Feb 1974 [21 March 1973] 6911/74 Addition to 1447680 Heading G4A The Specification describes the way in which the entries in the chain list store of the Specification 1,447,680 are established and maintained. The operating system produces a current virtual address and a corresponding current real address or a sequence of such addresses. The page part of the current virtual address is concatenated with a base address to access the appropriate entry in a page table which is loaded with the page part of the current real address thereby to establish or update the page table. The page part of the current virtual address is then decremented and again used to access the page table so as to produce the page part of real address corresponding to the virtual page preceding the current virtual page in the program sequence of virtual pages. This real address is then concatenated with a base address to access the appropriate entry in the chain list store which is loaded with the page part of the current real address. The page part of the current real address is then used to access the chain list store which is loaded with the page part of the real address corresponding to the preceding virtual page. In this way each time a new entry is made in a page table or an old entry is updated (e.g. due to page relocation) the chain list store is updated so that it contains one entry for each real page in the working store, each entry, except those corresponding to the first and last pages in the sequence, giving the real address of the preceding and succeeding pages in the sequence of virtual pages. - Additional data, e.g. data indicating that the succeeding page may only be used in certain circumstances, or store protection data, may be stored in the chain list store.
