Title: Flame-start arrangements for engines
IPC: F02N19/06
Filed: 1971-11-16
Abstract: 1325511 Flame-start installation for an internal combustion engine DAIMLER-BENZ A G 16 Nov 1971 [21 Nov 1970] 53174/71 Headings F1K and F1B A flame start installation for an internalcombustion engine comprises an electric switch which permits continued operation of the installation after the engine has started only if a predetermined minimum engine speed is maintained. As shown a relay 3 is energized by way of a contact 2 on the engine starter switch and switches on the motor driven pump 1 thus rendering the flame start installation operative. On completion of the engine starting operation, operation of the flame start installation is maintained by an engine speed monitor 5 with a switch connected in parallel with the contact 2. The installation is also controlled by a thermosensitive device 4 responsive to the temperature of the engine cooling water.
Patent GB-542362-A (GB)
Abstract: 542,362. Workmen's time recorders. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 3, 1940, No. 9724. Convention date, June 10, 1939. [Class 106 (iv)] [Also in Group XVI] A card-controlled mechanical trip-device for the impression-hammer of a time-recorder or like machine comprises a card-operated lever mounted on an adjustable card-abutment and co-operating with a bail in connection with a trip which abuts on a hammer-latch. Provision may be made for restraining the trip to prevent repeat operation, and for power-return of the hammer and associated parts. In the time-recorder shown in Figs. 1 and 3, a hammer 21, mounted on a shaft 36, is urged towards type-wheels 23 by a spring 22 and is normally restrained by a latch 19 on a shaft 20. A bail 15, mounted on vertical pivots, engages a trip 17 which abuts on the tail 18 of the latch. The bail engages also a bell-crank 14 which is arranged in the path of the card C and is mounted on an adjustable card-abutment 12. When the card is inserted, the bell-crank and bail cause the trip to release the latch, and the hammer is fired. Thereupon, the tail of the hammer rocks the shaft 20, an arm 20a thereon depresses the trip 17 to prevent repeat operation of the hammer if the card is held down, and another arm 25 closes motor-contacts 26, and permits a pawl 27, mounted on a cam 32, to engage a ratchet-wheel 29 on the motor-shaft 31. During revolution of the cam, an arm 37 is rocked to maintain closed the contacts 26, and to retain the shaft 20 and latch 19 in displaced position. Near the end of a revolution, an eccentric 33 on the cam rocks the shaft 36 to restore the hammer, the arm 37 returns, and the latch re-engages the hammer. For preventing printing under certain conditions, even if a card is inserted, the trip 17 is depressed by a finger 50a on a bail 50 in connection with a link 40 which is operated by a cam 42, a cam 43, or a bellcrank 47 during a programme-change, a hammercycle, or when the card-receiver 11 is displaced. Specification 530,208 is referred to.

The pivoting action is provided by cooperating cylindrical surfaces on the nozzle and the body. Switch 46 has an actuator 46a spring- biassed to the on position but movable to the off position by lug 44 on the nozzle. Catches 36 are spring-biassed outwardly through slots in the nozzle wall, Fig. 6 (not shown) and engage a lip 126 on the body to releasably lock the body in its vertical non-operative position. The motor may be driven at one of two speeds selected by switch 134 and a lamp 136 is arranged to be illuminated whenever the motor runs, a transparent section 74 being provided in the wall of the body in front of the lamp. The dust is separated in a filter bag attached by a rubber ring to exhaust conduit 54, and filtered air passes through filter 100 and screen 102 into the motor compartment, past the motor 96 and lamp 136, and out of the body through vents 76. A cap 110 may be removed from an aperture 106a in the wall of the suction channel 56 to allow a suction hose to be connected. The nozzle 11 consists of an upper part 14 and a lower part 16 held together by a rubber bumper band 18.

The innermost cylinder 1 may be heated by an electric coil 6 and a platform 11 is provided to support the specimen being heated. The tubes may be of ceramic material, or the inner one may be of heat resisting glass and the outer ones of aluminium or stainless steel. The tubes are supported in concentric grooves in end plates which are insulated by further plates spaced from them by cylindrical members at their perimeters. The specimens are inserted through central openings in one of the end plates and the further plate. The cylinders 2, 3 have radiation shields in the form of reflective layers 12, 13 and they may also be cooled by liquid or gas. A layer of insulation 40 is provided round the inner tube, e.g. a fibrous refractory material. The spaces 4 and 5 may be evacuated or provided with insulating material. To prevent oxidation of reflecting surfaces where these are provided the spaces may be filled with an inert gas or provided with a material to absorb oxygen. In the form of Fig. 3 the innermost tube 61 is of a refractory material, e.g. silica, the heating coil 66 being wound round it and covered with cement 660. The specimen to be heated is inserted in a work tube which projects from tube 60 through the extension tube 76 which is also of refractory material. The innermost tube is insulated by ceramic wool 640 bound with wire 67, an internally polished stainless steel tube 62 and a lined steel or aluminium tube 63. A further ceramic tube 68 is clamped by band clips 71 to end plates 70, e.g. of asbestos composition, each of which is separated from spacing rings 74, 75 and 78 by a mass of ceramic wool 77. The outermost casing 73 is supported on an instrument unit 80 having a temperature gauge 81, a temperature control 82 and an ammeter 84 for the heating current. In a modification (Fig. 5, not shown) the innermost tube is of square section and is closed by a refractory brick door operated manually by a linkage mechanism.

Title: Process for the preparation of epsilon-caprolactam
IPC: C07D201/10
Filed: 1966-12-06
Abstract: e -Caprolactam is prepared by subjecting a compound of the formula <FORM:1109376/C2/1> where X is hydroxyl, alkyl or aryl to the action of a nitrosating agent in the presence of polyphosphoric acid.  The nitrosating agent may be, for example, nitrosyl sulphuric acid, nitrosyl-sulphuric acid anhydride or sodium nitrite. The group X may be of the formula -Y-R where Y is a phenyl or naphthyl residue and R is hydrogen or alkyl of 1-7 carbon atoms.  The nitrosation is preferably carried out at 20-220 DEG  C. using 0.1-2.5 mols. of nitrosating agent per mol of compound.  The compound where X is -Y-R is prepared by the reaction of cyclohexane carboxylic acid, its anhydride or a derivative thereof which is converted into the free acid under the reaction conditions, with an aromatic compound of the formula H-Y-R, in the presence of polyphosphoric acid.  The two reactions can be combined into a process for the simultaneous production of e -caprolactam and an aromatic acid from cyclohexane carboxylic acid and the compound H-Y-R.

Annular cavities between thrust bearings 12 and member 13 and tubes 29 respectively thermally insulate the bearings. The tubular member 13 and the series of tubes 29 constitute the "rotatable carrier". Cooling liquid stored in radial passages 17 is vaporized by heat generated in the disc and the vapour is displaced inwardly by liquid flowing centrifugally outwardly; the vapour passing along respective passages 18 is condensed at the end where cooling fins 19 are provided. In Fig. 1, not shown, hub flange 24 and tube 29 are omitted: instead, member 13 (and passages 18) is continued to the end of hub 10 and has an integral inwardly-directed flange secured by bolts to the end of hub 10, and is in contact with the hub between bearings 12.
