Title: Electric driving device
IPC: H02P6/20
Filed: 1967-09-11
Abstract: 1,141,414. Electric motors. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 11 Sept., 1967 [14 Sept., 1966], No. 41330/67. Heading H2A. [Also in Division G1] The current through the stator windings of a commutatorless electric motor is switched by electronic switches controlled on starting by an auxiliary photo-electric arrangement including a light source which is extinguished when the induced e.m.f. in the stator windings reaches a predetermined value which is sufficient to directly control the electronic switches. The motor has a polarized rotor and a stator having at least two stator windings and operates from a D.C. source. As shown, stator windings 1, 2 are supplied from D.C. source 4 through transistor switches 5, 6 which are rendered conducting alternately by the e.m.f. induced in the non- energized stator winding. On starting when no induced e.m.f. is present screen 12, rotating with the permanent magnet rotor, allows light sensitive resistors 9, 10 to be illuminated alternately from lamp 8 to operate switches 5, 6. When the rotor is running the induced e.m.f. charges capacitor 30 through diode 29 until it counteracts the forward bias on transistor 25 and renders it non-conducting to switch off lamp 8. Alternatively the lamp is connected in series with the stator windings so that after the motor has started the voltage drop across the lamp reduces to less than its operating voltage and it is extinguished. A motor having three stator windings connected 120 degrees elect. apart and using phototransistors to control the electronic switches is also described, Fig. 2 (not shown).

Filed: 1973-09-07
Abstract: 1437112 Semi-conductor device MULLARD Ltd 7 Sept 1973 42131/73 Heading H1K In a method of manufacturing a semi-conductor device wherein a surface of a silicon semi-conductor body is selectively masked against oxidation, a recess formed in the unmasked portions of the surface and the recess oxidized, the side wall of the recess is provided with a layer which inhibits lateral oxidation of the body underneath the mask. A semi-conductor body 3 having masking layers 5 of silicon oxide and nitride has a recess formed. The recess and the masking layer are covered with a nitride layer 16 and an oxide layer 17. A thin coating (18, Fig. 6, not shown) of aluminium or chromium is formed over oxide layer 17 and coating of positive photoresist (19) provided. The photoresist is exposed but the portion underlying the overhang of the masking layer is shaded by the opaque metal layer (18). The exposed portions are removed to leave the unexposed portion which is used as a mask for the removal of the oxide and nitride layers 16, 17. The remnant oxide and nitride layers under the overhang inhibit rapid lateral oxidation when the recess 7 is oxidized. The nitride layer may, however, be wholly converted to oxide during the oxidation process. Bipolar and field-effect transistors optionally in integrated circuits may be made using this method. Oxidation of the recess may be allowed to penetrate a layer of one conductivity to a layer of opposite conductivity or an insulating substrate of sapphire. The recess may not be completely filled with oxide and the nitride layer may be formed on an intervening oxide layer with the nitride layer 16 in the recess extending up to join that of the masking layer 5.

In a second viewing area is displayed the last completed line and in a third viewing area is displayed the line under composition. The characters, commands and values are fed in from a keyboard and stored in a memory as well as being displayed in the first viewing area. Upon completion of a justified line all the data stored in respect of that line is transferred to a photographic printing unit and also displayed in the second viewing area. The printing unit comprises a rotating disc carrying several character fonts and associated timing marks so that the machine logic may energize a flash device to print a selected character. Font change is produced by radial movement of the disc. The characters are positioned by a travelling mirror. The film is moved for line spacing. A collimator and variator lens system is movable to produce point size changes by varying the image magnification. The selected font and point size are continuously displayed to the operator as an insert in the line under composition. Input of characters is inhibited until the appropriate command information has been input. Specifications 1,529,464 and 1,529,466 are directed to other features of the machine described.

Abstract: The bonding of rubber to polyethylene terephthalate tyre cord is improved by treating the filaments to be used for the manufacture of the tyre cord or the cord yarn or fabric with an alcoholic solution, aqueous alcoholic solution or aqueous emulsion of a glycidyl ether of an aromatic or cycloaliphatic polyhydroxy compound having two or more glycidyl ether groups and a heterocyclic or aliphatic amine, heating to 160 DEG -245 DEG C. and subsequently treating the product with an aqueous dispersion of a resorcinol-formaldehyde precondensate and a vinyl pyridine latex. The glycidyl ether may be the reaction product of epichlorohydrin with resorcinol, phloroglucine or pyrogallol and the amine may be piperazine, piperidine, pyridine, hexamethylene diamine, diisopropyl amine, dicyandiamide, dimethyl piperazine or guanidine.  The treated material may be heated to 160 DEG -245 DEG C. for 1-330 seconds.  The glycidyl ether and amine may be applied to the filaments prior to stretching or the cord yarn after stretching may be treated with the clycidyl ether and amine and then guided through a chamber in which a slight shrinkage can occur under the action of superheated steam or hot air, a temperature of 220 DEG -245 DEG C. preferably being used to set the treating agents.
