Title: Detection system for detecting synchronism between television video signals emanating from different sources
IPC: H04N5/275
Filed: 1976-05-04
Abstract: 1516434 Television THOMSON CSF 4 May 1976 [7 May 1975] 18249/76 Heading H4F A circuit for detecting synchronism between at least two television signals generates pulses I, of duration 2#t 1  delayed by T 1  from each sync pulse in one signal, and pulses Io having one edge Fo delayed by To from each sync pulse in the second signal and detects when edge Fo does not coincide with pulse I 1 . Such detection indicates a time difference between sync pulses of more than #t; i.e. non-synchronization. A monostable circuit at the output of the detector generates a pulse for at least one frame when non-synchronization is detected so that coincidence of line sync pulses without coincidence of field sync pulses cannot indicate synchronization.

Title: Improvements in or relating to valve-guides for internal combustion engines
Inventor: MARSHALL PETER ROBERT
IPC: F01L3/08
Filed: 1954-06-23
Abstract: 780,073. Making valve-guides. BIRMING- HAM SMALL ARMS CO., Ltd. Dec. 1, 1955 [June 23, 1954], No. 18365/54. Class 83 (2). A valve-guide, for an internal combustion engine poppet valve, is made by powder metallurgy and the surfaces adapted to be exposed to harmful fluids are coated with a corrosionresistant metallic coating. The guide is preferably made from iron powder and graphite which acts as a solid lubricant. After pressing the powder in a die, the resulting compact is sintered and a protective coating of copper, nickel, chromium, tin-nickel alloy, copper-tin alloy, iron, nickel-cobalt alloy, bronze, brass, silver solder or brazing solder is then applied by electrodeposition, spraying, or by depositing the end of the guide in a bath of molten metal which is drawn into the pores thereof by capillary attraction. The coating is preferably applied only to these surfaces exposed to corrosive conditions in use whereby the remaining surfaces may retain their porosity and be subsequently impregnated with lubricant. A flux may be used when the coating is applied by impregnation.

Abstract: 1,177,342. Separating hydrocarbons. BRITISH PETROLEUM CO. Ltd. 25 April, 1967 [27 April, 1966], No. 18386/66. Heading C5E. One or more components of a hydrocarbon mixture comprising C 8  and/or C 9 , alkyl and/or alkenyl, aromatic hydrocarbons are separated by a process comprising one or more fractionally crystallization stages, optionally one or more distillation stages, and one or more sorption stages in each of which the feedstock is contacted in the liquid or vapour phase with a compound having the basic nuclear structure: and which forms an inclusion complex more readily with one or more components of the mixture than with the other components, and desorbing the sorbed components therefrom. Suitable compounds are tris-(o-phenylenedioxy) phosphonitrile trimer, o - phenylenediaminophosphonitrile trimer and 2,3-naphthyldioxy phosphonitrile trimer. They may be used in the free state, or on a support, suitable supports being ground firebrick, diatomaceous earth, silica gel, alumina or porous glass, the support being preferably silanized. The feed may be diluted by an inert gas or liquid, and the subsequent desorption of the sorbed components may be effected by displacement with another sorbate, by elution with an inert gas or liquid, by reducing the ambient pressure, or by raising the temperature. A purging stage may be interposed between the sorption and desorption steps. Para-disubstituted benzenes are absorbed preferentially to mono-substituted benzenes, and both of these types preferentially to other types. The number and sequence of process stages may be varied according to the feed and the yields and purities of the products required.

Filed: 1972-04-20
Abstract: 1331037 Welding by pressure PRODUCTION TECHNOLOGY Inc 20 April 1972 [26 April 1971] 18420/72 Heading B3R [Also in Division H2] In a method of joining a stranded wire cable 66 to a connector piece 62, the wire 80 is inserted in a sleeve 64 so that end surfaces 84, 76 of the wire and sleeve are flush. The end surfaces are pressed against the end 70 of the connector piece rotated relatively thereto in order to friction weld the sleeve and wire to the connector piece. The sleeve may be collapsed on to the wire 80 and for this purpose may have a slot 82 which need not be parallel to the sleeve axis. The welding may be carried out using the machine in Fig. 1 where the cable and sleeve (WP-2) is gripped in a non-rotating chuck 16 mounted in tail-stock 18. The connector piece (WP-1) is held in a chuck 14 rotated via hydraulic transmission 28 by a motor 26. When the desired speed is reached the drive is disconnected and the chuck continues to rotate due to the inertia of flywheel 24. Tailstock 18 is then moved by cylinder 20. The method is particularly suitable for electrical components made of aluminium or copper but may also be used for joining hook or eye connectors to steel cable.

Abstract: 479,839. Compound sheet materials. GREIG, L. T. H. July 8, 1936, No. 18964. [Class 140] [Also in Group XXXIII] Components of aircraft are formed by winding tensile reinforcement material into the desired form of the component, also winding thereon or therewith into the same form unpregnatable strip material to form virtually continuous skins or laminµ and impregnating or embedding the whole in a cement-like substance capable of being hardened. As applied to the formation of a wing, a lattice work of tensile material in flat strip form is wound on a core 1, Figs. 1 and 2, and laminated by superimposing windings 2, 3 of opposite hand. The strips may be of textile fabric and may have longitudinal wires braided in or wound between the laminµ or may be of wire or metal ribbon. Each strand 2, 3 is anchored at end frame or other anchorage 4. The lattice is impregnated with cement. A covering of fabric strips 5, 6 is next applied and also impregnated with cement preferably during winding. The whole may be again treated before or after removal of the core. Where it is desired to form a window frame or other interruption of the general form, the interstices of the lattice may be locally widened by causing certain of the strands to run together for a distance and then to diverge to pick up the reticulated pattern. Elements such as struts or fittings may be embedded in the structure as shown in Fig. 5 where 10 is a threaded ferrule. The structure described may be reinforced with an internal framework and may have an outer covering of metal or fabric.

Title: Manufacture of carboxylic acid esters
IPC: C07C67/08
Filed: 1934-06-28
Abstract: Esters of carboxylic acids are produced by hydrolyzing a mixture containing dialkyl sulphates by heating with water until the dialkyl sulphate is wholly destroyed and reacting the mixture, containing alkyl hydrogen sulphate, with an inorganic salt of a carboxylic acid or free carboxylic acid or both, free sulphuric acid or excess of alkyl hydrogen sulphate being present at all times.  The alkyl sulphate mixture may be made by absorbing ethylene in sulphuric acid, a typical mixture being 50--55 per cent diethyl sulphate and 30--40 per cent ethyl hydrogen sulphate, the remainder being sulphuric acid. After hydrolysis of the diethyl sulphate for instance by boiling with water with agitation, about 80 per cent of the equivalent quantity of calcium acetate may be added.  In examples the hydrolysis is effected at 75--80 DEG  C. and the product is heated with: (1) calcium acetate; (2) acetic acid; (3) acetic acid and alcohol or acetic acid calcium acetate and alcohol.  Dilute aqueous distillate fractions are returned to the next batch.  The production of esters from the liquors obtained by absorbing propylene and butylene in sulphuric acid is mentioned.  The sulphuric acid remaining after the removal by distillation of the ester and unreacted alcohol and carboxylic acid may be concentrated at ordinary or reduced pressure to about 70--72 per cent strength and is then preferably heated under pressure to above its boiling-point, for instance 175--180 DEG  C. for 0,25--2 hours to carbonize organic matter so that it can be separated by filtration, after which the acid may be further concentrated to 90 per cent strength or more.ALSO:Sulphuric acid left after the production of esters from alkyl sulphates is concentrated at ordinary or reduced pressure to about 70--72 per cent strength and is then preferably heated under pressure to above its boiling point, for instance 175--180 DEG  C., for 0.25--2 hours to carbonize organic matter so that it can be separated by filtration, after which the acid may be further concentrated to 90 per cent strength or more.
