Title: Improvements in and relating to variable-speed gears
IPC: F16H37/08
Filed: 1935-04-03
Abstract: 454,444. Variable-speed gearing. ANDERSON, H. P. H., 19, Radcliff Road, South Kensington, London, and HENDERSON, A., 25, Chiltern Road, Sutton, Surrey. April 3, 1935, No. 10357. [Class 80 (ii)] A variable-speed gear comprises a system of epicyclic bevel pinions 6 on a carrier 4 driven by a driving shaft 3, a bevel gear 1 attached to the driven shaft, and a bevel gear 2 rotatably mounted on the driving shaft 3 and driven by it at a variable speed through a ratchet device 17, 16, 13, 15. The speed of the bevel gear 2, and therefore the driven bevel 1, is varied by varying the eccentricity of the ring 17 of the ratchet device, which is driven from the shaft 3 by a coupling 28, 30 which allows the relative displacement of the ring 17, the connection between this ring and the boss 7 of the gear 2 being by elements 13 pivoted to rings 8 secured to the boss 7 and having members 16 with ratchet teeth engaging alternately with teeth on the ring 17 at the point where the ring is least distant from the axis of the shaft 3 so that as the eccentricity is increased the boss 7 and gear 2 is driven correspondingly faster. The elements 13 are all geared together by teeth 14 engaging with a toothed ring 9 so that at any time only the element transmitting the drive engages with the ring 17, the others being held away by the gearing 14, 9 until they in turn take up the driving position. In a modified construction, the driving elements 13 are in the form of slides moving in radial guide slots in one member and having teeth adapted to engage with teeth on the other member. Each of the said slides has a pin engaging in slots in a common ring member so that the radial movement of any one of the slide members produces a corresponding movement of the others. The members 16 need not have ratchet teeth engaging with teeth on the drum 17 but may transmit the drive purely by frictional contact. Specifications 325,431, [Class 80 (i)], and 342,793 are referred to.
Patent GB-709674-A (GB)
Title: Oxidation of hydrocarbons
IPC: C07C51/215
Filed: 1952-04-25
Abstract: Liquid hydrocarbons containing less than 6 carbon atoms are oxidized in the liquid phase in a solvent medium containing an oxidation catalyst by means of gaseous oxygen with removal of water from the reaction mixture substantially as it is formed. Preferably a portion of the reaction mixture is allowed to distil over during reaction, condensed to allow of water removal by separation into phases, and the hydrocarbon phase returned to the reaction zone.  The aqueous phase may be treated for recovery of water-soluble products. Reaction temperatures of 125-225 DEG  C. and pressures of 200-2000 p.s.i. are preferred.  Air or oxygen may be used as oxidizing gas.  A ratio of 0.5-10 mols. of oxygen to each mol. of fresh hydrocarbon introduced is preferred.  Recycled hydrocarbon may range from 5-50 parts per part of fresh hydrocarbon introduced.  Preferably the oxygen is completely consumed.  Metal salts, especially of cobalt, nickel, copper or manganese with acetic, propionic, benzoic or naphthenic acids are preferred; 0.1-1.5 per cent by weight of catalyst based on solvent is used.  Specified solvents are acetic-acid, acetone, benzene and methyl or ethyl acetate.  The partial distillation may be assisted by the use of inert stripping gases.  The condenser is preferably maintained at -7 DEG -+25 DEG  C. In an example, n-butane in acetic acid with cobalt acetate is treated with air, a portion of the reaction mixture being distilled as above described, and mainly acetic acid recovered with some acetate esters and methyl ethyl ketone.

Title: Improvements in or relating to pulse generating thermionic valve apparatus
IPC: H03K5/01
Filed: 1940-06-17
Abstract: 581,561. Valve modulating circuits. BLUMLEIN, A. D., and WHITE, E. L. C. June 17, 1940, Nos. 10484/40 and 910/41. [Class 40 (v)] A circuit for generating short pulses of radiofrequency energy comprises a high-frequency valve-oscillator with high-voltage pulses applied to its anode circuit and provided with means for rendering the grid positive a predetermined time after the application of each pulse so as to damp the grid circuit and to cause the oscillation to decay rapidly. As shown in Fig. 1 (10484/40), high-voltage pulses are applied to the anodes of oscillator valves 4, 5 by interrupting the current flowing through a valve 1 and inductance 2, as in Specification 579,725. A lower voltage is applied to the grid circuit by a tapping on the coil 9 connected through.a time-delay network 10 and grid leak and condenser 11, 12. In a modified circuit, the network 11 is replaced by an inductance coil in series with the grid leak 11, 12 and a diode valve with its cathode connected between the coil and the grid leak and its anode connected to earth. In another modification, shown in Fig. 1 (910/41), a time delay network 6 is connected between the oscillator grid circuit and earth. At the start of the oscillations a negative pulse appears across the network and is propagated along it, being reflected at its mis-terminated outer end 5, and appearing after a suitable delay as a positive pulse on the grids and so causing the required damping. The time-delay network may be replaced by an inductance in series with a resistance-condenser combination.

Title: Improvements in or relating to memory matrices and the production thereof
IPC: G11C29/00
Filed: 1970-03-05
Abstract: 1,269,465. Read only memory. SOC. INDUSTRIELLE HONEYWELL BULL. 5 March, 1970 [6 March, 1969], No. 10739/70. Heading G4A. [Also in Division H1] The invention relates to a read only memory and to a process for fabricating a memory matrix. An insulating support 1 is coated with a uniform resistive layer 20 and then with a first conductive layer 21. A series of parallel notch pairs 22, 23 is cut through the two layers to form a rectangular mesh pattern and an insulating plate 14 is placed between each pair to overlap the notches. The plate may be a varnish uniformly deposited and cut by photo engraving. A further conductive layer is added and the three layers are etched to provide orthogonal bands 2, 3 and resistive lamellµ 5 connecting bands 2 and 3, bands 2 being formed by the layers situated between the notches and by the portions connecting these layers. Notches are cut in the top layer of bands 2 adjacent the cross-over points with bands 3. The memory may be covered with a photosensitive lacquer having windows partially exposing the lamellµ, selective lamellµ may be masked and the remaining lamellµ etched away to provide the memory. The lamellµ may have fusible portions situated between enlarged pads so that selected lamellµ may be destroyed by passing large currents through the fusible portions.

Title: Improvements in machines and methods for producing high intensity electric currents
Inventor: RIOUX CHRISTIAN PAUL GILBERT
IPC: H02K39/00
Filed: 1963-03-19
Abstract: 1,042,451. Dynamo - electric machines. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. March 19, 1963 [March 19, 1962], No. 10746/63. Heading H2A. An electrical machine comprises a rotor consisting of a high inertia mass 1 and an integral conductive sleeve 2 co-operating with a stator comprising conductive laminations such that when electrically conducting liquid is injected into gaps 8 with the rotor rotating at high speed a closed circuit is formed and a high intensity current pulse produced. The stator is a solid of revolution with cuts 9, produced by electro-spark machining thereby providing an effectively laminated construction as described below. Each stator lamination comprises oblique axially extending parts 5, radial parts . 6 and an outer section 7 having an axially extending central zone 7a, which is conductively joined to the adjacent laminations, and oblique marginal zones 7b to produce a C-shaped element so that when current flows in the direction shown a magnetic field is produced having radial and tangential components. In effect the machine comprises a normal D.C. series machine so that once the rotor speed is greater than a critical value, provision of a small magnetic field, either by the remanence of the components used or from an external coil will cause current build up when the circuit is completed by the injected liquid. The tangential radial field produced by the stator increases the excitation field and interacts with the current in the rotor to convert the kinetic energy of the rotor mass into a high intensity current pulse. The rotor may be driven up to speed by a small electric or fluid-powered motor. It is preferable that the part of the stator immediately adjacent the rotor is not laminated thereby reducing the parasitic eddy currents. The stator may be made fluid-tight in order that a gas plasma can be produced at 10 by the high intensity magnetic field, alternatively the current pulse may be led to terminals for use in an external circuit. In modifications, two oppositely-rotating annular rotors, which may be laminated, are used and co-operate with two stator members which are located both inside and outside the rotor, Figs. 5-8 (not shown). Alternatively, the rotor may comprise an enlarged diameter shaft portion integral with a flywheel cooperating with a stator comprising annular spaced-apart laminated structures which are connected to an external load. This machine may be further modified by making part of the co-operating faces of the stator and rotor curved. The injected liquid which may be mercury or other conductive liquid metal or metal alloy is introduced under pressure to ensure rapid filling of the gaps which are axially disposed to avoid centrifugal pressures. The downstream ends of the gaps may be provided with an adjustable throttle member and improved outflow is facilitated by centrifugal action in radial passages.

Title: Improvements in and relating to the production of pseudoxazolone derivatives and reduction products thereof
IPC: C07D263/42
Filed: 1944-06-07
Abstract: Pseudoxazolone derivatives of the general formula <FORM:0602025/IV(b)/1> where R is hydrogen or a hydrocarbon group are prepared by subjecting a -halogenoacylamino acids of the general formula CO2H.CHR-NH-COCH (hal) R1 to treatment with a tertiary nitrogen base or a strong inorganic base and a dehydrating agent.  An essential condition for the success of the process is that the group R.CH= is of such a character that the formation of the unsaturated group (R minus H)=C= cannot occur in the removal of H.Hal, such as where R is H or phenyl.  The compounds so produced may be hydrogenated to oxazolones.  In examples: (1) a -bromophenacetylglycine is treated with acetic anhydride and pyridine; (2) a -bromphenacetylalanine is similarly treated; (3) a -bromphenacetylalanine is mixed with pyridine, the separated pyridinium bromide treated with more pyridine and acetic anhydride; (4) as in (2) but using an N-sodium hydroxide solution of a -bromophenacetylalanine; (5) phenacetylalanine is heated with acetic anhydride and then treated with pyridine and bromine; (6) mandelylaline, made by condensation of alanine with acetylmandelyl chloride, is treated as in examples (1)-(4) above; (7) 4-methyl-2-benzylidenepseudoxazolone is hydrogenated in ethyl acetate solution in presence of a Raney nickel catalyst to form 4-methyl-2-benzyl-oxazolone.
