Patent GB-613705-A (GB)
Title: Process of preparing new substituted thiobarbituric acids
Filed: 1946-06-25
Abstract: Allyl - (1 - ethylpropyl- and 1 : 2 - dimethyl - propyl)-barbituric acids are manufactured by condensing thiourea with a substituted cyanoacetic ester of the formula <FORM:0613705/IV(b)/1> (wherein R represents a 1-ethylpropyl or 1 : 2-dimethylpropyl group and R1 a common esterifying radical, e.g. methyl, ethyl, propyl or isopropyl), preferably in the presence of about two molecular proportions of metal alcoholate (e.g. sodium ethoxide or methoxide), and hydrolysing the resulting imide, e.g. by heating with a mineral acid such as dilute hydrochloric acid. The products may be purified by dissolving in alkali and reprecipitating with acid, followed by recrystallization from a solvent, e.g. alcohol, and they may be converted into salts by treatment with a metal hydroxide, e.g. sodium hydroxide.  Substituted cyanoacetic esters of the general formula above are obtained by condensing a cyanoacetic ester with an equimolecular proportion of diethyl ketone or methyl-isopropyl ketone by the Knoevenagel reaction (e.g. in the presence of ammonium acetate and glacial acetic acid in benzene), reducing the condensation product by means of hydrogen in the presence of a hydrogenation catalyst, e.g. palladium-charcoal, and treating the reduced compound with an allyl halide (e.g. chloride or bromide) in the presence of a metal alcoholate (e.g. sodium ethoxide).

Title: Process and catalyst for the conversion of hydrocarbons
IPC: B01J23/04
Filed: 1944-10-11
Abstract: A catalyst for hydrocarbon conversion processes comprises a major amount of a synthetic alumina gel containing between 0.1 and 1 per cent. of an alkali metal and a minor amount above 8 per cent. (preferably 12-25 per cent.) of boric oxide.  The alkali metal may be introduced as a hydroxide, nitrate, sulphate or acetate, and the boric oxide as boric acid, or as an alcoholic solution of boric oxide.  The added substances may be incorporated by mixing with the wet hydrous alumina gel prepared by precipitation of an aluminium salt solution with ammonia, or by impregnation into the dried gel. Alternatively the required amount of the alkali metal salt may be added before precipitation of the alumina gel by ammonia, or precipitation may be effected by alkali metal hydroxide, and the excess alkali metal washed out of the gel.  Before inclusion of the added substances the washed gel may be peptised by treatment with dilute acetic acid.  The final gel may be calcined at 600 DEG -1100 DEG F. and may be in the form of a fine powder, spherical marbles, or pellets.  Cracking of a hydrocarbon oil using the above catalyst may be effected under 1-5 atmospheres pressure at 750 DEG -1100 DEG F., with a contact time of 0.5-30 seconds; a fluidized catalyst, moving bed, or fixed bed system may be employed.  Other hydrocarbon conversion processes in which the catalyst may be used include isomerization of olefines, reforming of gasolines and naphthas, and dehydrogenation of naphthenic hydrocarbons.

Title: Process and apparatus for the sterilised filling of liquids, more especially beverages like beer, fruit juices and the like, into glass bottles having a suitable closure
IPC: B67C7/00
Filed: 1932-07-14
Abstract: 407,672. Sterilizing empty cleaned bottles. SCHLOR, F., Menziken, Switzerland. July 14, 1932, No. 19869. [Class 138 (i).] In a method for sterilizing empty previously cleaned bottles, in which the bottles are subjected to the action of wet steam in a sterilizer, the bottles are conveyed gradually from a cool zone into a region of increasingly hot steam vapours, remain in the hottest steam vapours for a period sufficient to effect sterilization, and are then conducted gradually into a region of increasingly cool steam vapours or cooler air. The method is especially for use with immediately succeeding bottling and bottle-sealing operations. As shown, a conveyer 2 feeds bottles 1 carrying protective cups 5, preferably of magnetizable material or coated with such material, through an opening 9 in a chamber 4 on to trays 11 carried by chains or ropes 10. The bottles are conveyed along the path shown, past the guide-rollers 13-21. Steam jets 91, 92, 93 keep the top of the chamber hot, and a refrigerator, comprising brine-filled pipes 39, keeps the bottom cold, the chamber being divided by baffles 34-38. A blower 25 sucks from the chamber 4, via pipe 24, cooled steam vapours, and from near the workroom ceiling, via pipe 26, steam vapour. This vapour, with cold air from the lower region, is forced into a washer 29 and then, by a blower 32, through a pipe 33 into the lower region, passing between the baffles 36, 37, 38. The bottles are removed through an opening 40 and placed on a conveyer 42 in a cooling tunnel 43, which may be replaced by roofing and to which is supplied cold sterilized air, by pipe 47 from the blower 32, or cold sterilized water. Just after the bottles reach the bottling machine 44, the cups 5 are removed by an electromagnet and returned to the conveyer 2 for re-use. Into the machine 44 and the bottle-sealing machine 48, which have water seals, is blown steam or a steam-air mixture or sterilized air by injector nozzles. Crown corks to be sealed on the bottles are sterilized by a spray of hot steam or a jet of flame.

Abstract: 730,396. Toy trains. FEINTE, H. Aug. 8, 1952, No. 19998/52. Class 132(3). [Also in Group XXX] A railway signalling system for a railway track with signals normally at danger (see Group XXX) and adaptable for toy railways comprises an L-type impedance chain connected to insulated sections 2a ...2g ... ,Fig. 1, of one rail wherein a line 4 from one pole of a source 5 feeds the parallel arms 6a ... 6g ... (resistances) of the chain, while the series arms are polarized relays 3a ... 3f ... which connect adjacent sections 2a, 2b ...2f, 2g ... the other pole of the source 5 being connected to a continuous rail 1 and the polarized relays being such as to respond only when a sufficiently high current passes therethrough on presence of a train in a section, e.g. 2d, such a current requiring ahead sections i.e. 2e, 2f to be free to clear the entry signal for such ahead section 2e. The signals consist of green and red lamps 10, 11, respectively, Fig. 4, connected in series between the rail 1 and the line 4, a resistance 12 being connected across the green lamp 10. Operation of the relay e.g. 3a to close contact 8a, short circuits the red lamp 11b so that the green lamp 10b receives sufficient current to illuminate it. When the relay is unoperated the current through the green lamp is insufficient for illumination but the current through the red lamp is sufficient for illumination. The polarized relay 3a, &c. on operation also connects power from the source 5 directly to the corresponding section 13a, &c. of the traction rail 13 . The traction power source may be a different source to the source feeding the relays and it may be a D.C. or an A.C. supply, being used at the same time to feed the signal lamps. The resistance 12 may be a relay winding, the relay operating when the red lamp is short circuited to connect up the source of traction power to the corresponding traction rail section 13a, 13b &c. The system may be used for traffic in both directions in which case an individual traction power rail or trolley wire is necessary for each direction.

Filed: 1972-04-29
Abstract: 1430767 Motor vehicle safety systems PEKTRON Ltd 24 April 1973 [29 April 1972] 20008/72 Heading B7H A system for inhibiting starting of a motor vehicle engine until the driver has fastened his seat belt comprises a first switch S1 activated when the driver sits in the driving seat, a second switch S2 incorporated in the seat belt buckle or reel so as to be actuated when the belt is fastened or extended, and a control circuit which permits starting of the engine only if both switches S1, S2 are actuated in the correct sequence. When the driver sits on the seat, closure of the switch S1 energizes a bi-stable transistor circuit, one transistor T3 of which is consequentially set in the "off" condition so that a positive current flows through a resistor R18 to operate a switching circuit including a transistor T13 which inhibits current supply to the starter solenoid S or to the engine ignition system when it is in the off condition. Subsequent closure of the switch S2 when the seat belt is fitted causes a trigger circuit including a transistor T1 to produce a signal which switches on the transistor T3 so that the switching circuit permits starting of the engine. Once starting is permitted the transistor T3 remains on even if the seat belt is unfastened or the driver rises briefly from the seat so that the ignition supply is not interrupted. Switches S3, S4 associated with the front passenger's seat and seat belt are connected to additional bistable and trigger circuits which can operate the switching circuit. An alarm buzzer B and lamp L are energized by a warning circuit including transistors T4, T5, T6 when engine starting is inhibited or the driver's or passenger's seat belt is unfastened with the engine running. A switch S5 is operated by selection of a gear or release of the hand brake so that the engine can be run with the driving seat occupied and the belt unfastened without the alarm operating provided that the gear shift mechanism is in neutral or the handbrake is applied.
