Title: Improvements in and relating to electric power supply apparatus
Inventor: WALTER GEORGE OSCAR
IPC: H02M3/156
Filed: 1962-10-22
Abstract: 1,064,942. Automatic voltage control. A.P.T. ELECTRONIC INDUSTRIES Ltd. Jan.22, 1964 [Oct.22, 1962], No.39849/62. Heading G3R. An electric power supply apparatus includes a series control element between an input and an output, and means for controlling the voltage at the input as a function of load current and of the voltage across said element. As shown, a voltage regulator comprises a first stage including a switching transistor 12 which provides the input to a second stage including a series resistor 23 and a series transistor 13 the impedance of which is controlled in known manner to provide a stabilized voltage at output terminals 11. A voltage proportional to the voltage across the transistor 13 and to the load current through resistor 23 is derived from a voltage divider 41, 42 and is applied to an amplifier 25 together with a reference voltage derived from a Zener diode 33. The output from amplifier 25 controls the switching rate of transistor 12; thus when the load current is at its maximum, the output voltage of the first stage is reduced so that the voltage across transistor 13 is at a minimum value consistent with the transistor not being in a saturated condition, and when the load current is at a minimum value the output voltage of the first stage is increased. The arrangement thus enables the transistor 13 to be operated at a point near its condition of maximum dissipation, without risk of damage.

Filed: 1961-11-10
Abstract: 939,747. Laminates. ALLMANNA SVENSKA ELEKTRISKA A.B. Nov. 10, 1961 [Nov. 11, 1960], No. 40278/61. Drawings to Specification. Class 140. [Also in Groups XXXV and XXXVI] An electrically insulated high-voltage conductor, such as a high-voltage coil, has a bandage of insulating material, wrapped in several layers around the conductor and comprising a self-carrying layer of mica flakes, which may be made by a process similar to paper making, and a backing layer to which the mica layer is bonded by a softener-free foil of thermoplastic material, the bandage being impregnated with a resin which is completely polymerizable. The thermoplastic foil is preferably polyethylene glycol terephthalate or a polycarbonate foil, but may comprise polyamide, polystyrene, polypropylene, polyvinyl chloride or polyvinylidene chloride, and the backing layer is preferably of woven glass fibre though asbestos, cotton, silk and paper could be used. Suitable resins are epoxy, alkyd and phenolic resins. The laminated bandage is produced by passing the three separate layers between a pair of heated rollers so that the bonding takes place only at the surface and so causes no obstruction to the flow of impregnating fluid, which flow is further helped by perforating the bandage, with a spiked roller, over less than 10% of the area so as to reduce the risk of holes right through the insulation when in position. The insulation is dried in a vacuum before impregnating it at pressure.

Abstract: 933,336. Jointing. B. P. J. CIRELLI. Nov. 27, 1959 [Nov. 28, 1958], No. 40487/59. Class 83 (4). A method for repairing broken or cracked parts, in particular cast or moulded machine parts, in which two sections located on opposite sides of a break or crack in a part are connected by one or more insert elements fitted transversely to the line of break in recesses formed in each part and locked by providing complementary slots in the adjoining wall surfaces respectively of each insert and its recess to form a series of subrecesses, and driving into the sub-recesses so formed wedge members having only limited portions of their perimeter in contact with the sub-recess walls, these portions being so oriented to the break that most of the oppositely acting forces exerted operate in directions perpendicular to the break, the slots in the insert having contact surfaces for the wedges a greater mean distance from the break than have their complementary slots in the recess, the resultant forces thus tending to force the broken sections together, whilst those forces tending to force apart the sides of the recess from the insert are minimized. Figs. 1, 2 and 3 show a metal part 1 having a crack 2 repaired according to the invention using bars 3 and tapered wedge members 6. Figs. 8, 9 and 10 show modifications of the invention using circular, square and rectangular tapered wedge members 7.

Abstract: 1,273,176. Scanning apparatus. MULLARD Ltd. 14 Aug., 1969, No. 40738/69. Heading H4F. A mirror and torsion wire combination M1 is mounted on a body CA for oscillation about a first axis of the body at the natural resonance frequency determined by the wire and moment of inertia of the mirror, and the body itself is oscillated about an axis transverse to the first axis, thus performing line and frame scans respectively, the frame frequency being less than the line, or natural resonance, frequency, and being related to and synchronized with the line frequency in that the oscillation of the body is timed from the oscillation of the mirror. As shown, a vane secured to the mirror swings in the gap of a vane switched oscillator VSO to produce an output therefrom once per cycle of oscillation of the mirror. The output is shaped and amplified and fed to an electromagnet which couples with an armature on the mirror to sustain oscillation at line frequency. The output is also fed via a switch ES to a multi-pole stepping motor driving the body CA by an eccentric or cam arrangement. Such apparatus may be used in infra-red thermography employing a single cell detector, the output from which may be fed to a cathode ray tube having a long persistance phosphor. Line and frame frequencies of 96 Hz and 1 or 2 Hz respectively are mentioned.

Title: The preparation of cyclic diketones
Inventor: ROBINSON ROBERT
IPC: A23L27/20
Filed: 1960-11-28
Abstract: A cyclic diketone is made by reacting glyceraldehyde, or any compound capable of giving rise to glyceraldehyde in the presence of alkali, with a ketone containing the group -CO.CH2- in the presence of an alkali catalyst and obtaining the cyclic diketone from the reaction product. Instead of glyceraldehyde there may be used glycidaldehyde or carbohydrates such as glucose. Examples of ketones are diethyl, ethyl propyl, ethyl isoamyl, and methyl ethyl ketones or acetone. The alkali catalyst may be an alkali metal hydroxide.  The reaction is best effected in the presence of 20 to 200% by weight of water based on the other reactants. Except when using glycidaldehyde, the reaction mixture is preferably refluxed.  The product may be recovered by saturating the reaction mixture with an inorganic salt, the unwanted by-product extracted with a solvent, the aqueous layer is acidified and the product is extracted with a solvent (e.g. ether or benzene). Examples describe the preparation of 3 (or 5)-methylcyclopent-2-en-2-ol-1-one.
