Title: Improved method and device for heating incandescent cathodes of electric discharge vessels
IPC: H02M7/10
Filed: 1936-02-06
Abstract: 460,739. Rectifying alternating current. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Feb. 6, 1936, No. 3666. Convention date, Feb. 8, 1935. [Class 38 (ii)] In a high-tension rectifier system, the rectifier cathodes are heated by high - frequency currents supplied from a separate source through at least one high-tension condenser which separates the high-frequency source from the high-tension circuit. High-frequency current from the source 15 flows through the cathodes of the series-connected rectifiers 17 .. 21 round the external circuit comprising high-tension condensers 3 ... 7, the condenser 16 isolating the main low - frequency supply transformer 1, 2 from the highfrequency source 15. The condensers 3, 4, 5 form one group while another group is formed by 6, 7, joined at one end through the transformer 2 and at the other through auxiliary condenser 14 and inductance 32. Blocking resistances are included in the anode circuit of each rectifier to exclude high-frequency currents, and the cathode circuits comprise resonant circuits 28, 23, &c. tuned to the frequency of source 15 ; by this means losses due to the condensers 3 ... 7 are minimized. Alternatively, current transformers may be used, one for each cathode.

Filed: 1954-02-09
Abstract: 761,892. Cricket &c. balls. TWORT, T. R. Feb. 7, 1955 [Feb. 9, 1954], No. 3788/54. Class 132(2). Relates to covers for cricket and like balls in which the cover consists of two hemispherical cups each made up of two quarter sections 10 joined by a stitched band 11, the band being flanked on each side by a false quarter section lining 10a, Fig. 3, to take up the thickness of the band. In the known form, Fig. 3, the linings 10a are bevelled off at 10b towards the edge of the cup to accommodate the seam joining the two cups and this leaves the perimeter of the cup uneven because the ends of band 11 stand proud of the bevelled edge of linings 10a. According to the invention, Fig. 7, the false quarter sections linings 10a are of constant thickness and an additional lining 12 having a bevelled perimeter 12a covers the linings 10c and the band 11. The additional lining 12 and the linings 10c may be formed from a single piece of material suitably grooved to receive the band 11, or the lining 12 may consist of more than one piece of material.

Title: Digital computer control system
Inventor: KELLY MICHAEL JOHN
IPC: G06F9/26
Filed: 1966-01-28
Abstract: 1,073,106. Microprogramming. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 28, 1966, No. 3855/66. Heading G4A. In a computer control system, the address of a control word in a read-only store is derived, at least in part, from comparisons of condition data with a part of the preceding control word and predetermined control data. In Fig. 1 (not shown), bits from the current control word from a microprogramme readonly store are stored in a first register (1) and decoded (3) to select one of n AND gates (5), each also fed with a respective condition bit (e.g. error latch on, overflow), the AND gate outputs being ORed (6) to provide one bit of the address of the next control word. Another address bit is derived in an analogous way, the register involved (2) storing bits which do not change at each microprogramme step, from either the control word or a keyboard or data being processed. Fig. 2 (not shown) shows a modification in which only one OR gate is used, receiving all the AND gate outputs. Fig. 3 (not shown) shows an alternative modification in which the second address bit, if one, forces the first address bit to be zero and resets the second register (2) through a delay (12) and, if the first bit was one, sets a latch (13) providing a condition input to one of the first AND gates (5) for use in the following microprogramme steps. A reset for the latch (13) is also provided. The over-ride (forcing) facility may be provided for other conditions, enabling them to be examined in a given priority order, by duplicating the latch (13) etc, In all cases, further address bits can be obtained in a similar way or directly from the current control word.

Abstract: A polyolefin object e.g. a plaque, blow moulded bottle, biaxially oriented film, is coated by a method wherein the area to be coated with a coating composition such as paint or lacquer e.g. alkyd, nitrocellulose, acrylic or chlorinated rubber lacquers or latex paints, is first coated with an amorphous propylene polymer that has been modified by being reacted with an ethylenically unsaturated carboxylic acid or anhydride containing a sufficient number of carboxyl groups and anhydride groups that are equivalent to carboxyl groups to supply from 0.15 to 5.0% of carboxyl groups by weight of the modified polymer.  The amorphous propylene polymer may be amorphous polypropylene, or a copolymer of amorphous propylene and a copolymerizable ethylenically-unsaturated hydrocarbon monomer e.g. ethylene, butene -1, or ethylene and dicyclopentadiene, containing at least about 20 mol. per cent of propylene units.  The amorphous propylene polymer may be reacted with acrylic, methacrylic, itaconic, fumaric, crotonic acid or maleic anhydride.  The modified polymer may have a reduced specific viscosity of from 0.5 to 5.  The modified polymer may be applied e.g. by brushing or spraying, in the form of a solution e.g. in hydrocarbons or chlorinated hydrocarbons, containing 1 to 15% by weight of the polymer.  The polyolefin object may be of high density polyethylene or stereo regular polypropylene.  The coating is dried by baking at a temperature of 180 to 275 DEG F. for 10 to 30 minutes.
