In a system of the kind in which the output of a transformer-coupled transistor relaxation oscillator is rectified to provide a D.C. supply, the D.C. output voltage is stabilized by controllers the base emitter potential in accordance with a voltage derived from an auxiliary winding on the transformer. In one embodiment the transistor 1 together with transformer windings 6, 8 and low-voltage supply from a relaxation oscillator as disclosed in Specification. 763,445 and the high-voltage pulses induced in winding 6 when the oscillator cuts off are rectified at 10 to supply a load 12. The amplitude of oscillation is determined by the bias voltage across a resistor 19 in the base/emitter circuit of transistor 1. Resistor 19 is also included in the base/collector circuit of a transistor 14 to the emitter of which is applied a portion of the oscillator voltage obtained from an auxiliary winding 13 and a reference voltage 18. Then if the emitter becomes more positive than the base due to a rise in oscillator voltage, the transistor 14 conducts and produces a positive bias for the base of transistor 1. In a modification, Fig. 1, of the drawings accompanying Provisional Specification 1514/55, the highvoltage D.C. load is supplied from a separate winding 14, and the output of the control winding 13 is rectified at 15 and compared with a reference voltage 16 to provide the bias across resistor 19 in the base/emitter circuit of the oscillator transistor 1.

Patent GB-756902-A (GB)
Title: Improved platinum catalysts
IPC: B01J27/13
Filed: 1954-10-18
Abstract: A catalyst, especially for use in reactions involving dehydrogenation and isomerization of alkyl-substituted C5-ring naphthenes to aromatic hydrocarbons, comprises a carrier material in which is incorporated platinum and a minor proportion each of aluminium fluoride and aluminium borofluoride. The carrier is preferably alumina, but silica gel, activated carbon, diatomaceous earth, magnesium sulphate, asbestos, high silica glass, microporous zirconia gel, and activated bauxite may also be used; in some cases a non-porous carrier, such as porcelain or metals, is suitable.  The amount of platinum may be 0.05-1 per cent by weight of the catalyst and the amounts of aluminium fluoride and aluminium borofluoride each at least 0.03 moles (e.g. 0.16 moles) per kilogram of catalyst.  The catalyst shows increased activity in the dehydroisomerization of methylcyclopentane to benzene as compared with platinum catalysts containing aluminium fluoride and borofluoride separately, and catalysts containing boron phosphate with or without magnesium oxide or zinc fluoride.  In an example solutions of aluminium fluoride and borofluoride, prepared by dissolving alumina gel in solutions of hydrofluoric acid and fluoboric acid respectively, are incorporated with alumina gel together with tetrammine platinous hydroxide solution, and the product dried and reduced in hydrogen.  The platinum and the fluorine compounds may be distributed evenly throughout the catalyst particles or may be applied to the surfaces of the particles.  When the reaction involves the conversion of two reactants, only one of which requires isomerization, e.g. the simultaneous conversion of C6-ring naphthenes and C5-ring naphthenes, the fluorine compounds may predominate near the centre of the catalyst particles and the platinum near the surface.  For this purpose the surface of the particles may be partially neutralized with an alkaline-reacting material, e.g. a compound of calcium, magnesium, barium, zinc, lithium, sodium or potassium.  The catalyst may be used in the hydroforming of gasolines and naphthas, and reference is made to its use also in the dehydrogenation of olefins to diolefins and in oxidation reactions.

Abstract: 787,529. Automatic voltage and current control systems; supply systems for consumption apparatus; exciting arrangements for generators. ECLAIRAGE DES VEHICULES. SUR RAIL. Oct. 19, 1955 [Oct. 19, 1954], No. 29906/55. Classes 35 and 38 (4). In a generating system for providing current at a constant voltage and polarity, e.g. for vehicle lighting, an amplidyne generator has its excitation controlled by a vibrating-contact voltage regulator. An amplidyne generator A supplying a buffer battery B and load terminals 28, 29 comprises a series field 1, a starting field connected across the battery terminals and a control field 3. The control field is connected between the short-circuited generator brushes and the common point between a resistor 6 and the vibrating contacts 8 of a voltage regulator C, the latter elements being series connected across the generator output whereby operation of the contacts causes a reversal in control field energization. The regulator C also comprises a voltage winding 10 and a holding winding 11, the latter being energized from a shunt circuit for contacts 8 comprising a resistor 15 and an element 16 which may be linear or non-linear. A resistance-capacity circuit 13, 14 connected across contacts 8 improves the operation. The vibrating contacts 18 of a current regulator D, comprising also a current winding 20, are connected in series with voltage contacts 8 whereby the current output of generator A is maintained substantially constant until the battery voltage reaches its storage value, whereupon the voltage regulator takes over. The regulator D has a holding winding 21 and comprises other circuitry similar to that of regulator C. In a modification, Fig. 4 (not shown), the regulators have seriesconnected holding windings energized from a common circuit connected across the series arrangement of both pairs of regulator contacts.
