Title: Improvements relating to levelling devices for rising and falling structures
Inventor: MCNULTY FRANCIS JOSEPH
IPC: B64F1/32
Filed: 1961-04-12
Abstract: 952, 645. Levels. LLOYD'S PACKING WAREHOUSES (HOLDINGS) Ltd. July 9, 1962 [April 12, 1961], No. 13096/61. Heading G1F. [Also in Division B8] A platform, deck, or other structure which is raised and lowered by hydraulic rams acting at its corners, e.g. the aircraft loading platform described in Specification 920,101, is kept level as it rises and falls by attitude responsive switches, located one at each corner which control the flow of hydraulic fluid to and from the rams. Rams 1a-1d are supplied with pressure fluid through a conduit 7 and valves 4a-4d and exhausted through valves 6a-6d and a conduit 8. Mercury switches 18 are located one at each corner and interconnected by a conduit 19 so that the level of mercury within each switch is proportional to its height with respect to the others. When the platform is level the parts are as shown and contact is made between contacts 20, 21 in each switch. When a change-over switch 15 is in position 15a solenoids 14 of the supply valves 4a-4d are energized to open the valves and cause the platform to rise. If one corner rises more quickly than the others the mercury level in the associated switch will fall away from the contact 21 thus breaking the circuit to the solenoid 14 and closing the valve 4. The closure may be complete or partial and results in the corner concerned rising more slowly or stopping until the others reach the same level. During lowering, the switch 15 is in position 15b and the solenoids 14 of exhaust valves 6a-6d are open. Also contacts 16 are closed by a relay 17. If one corner moves down lower than the others the mercury in the switch rises until contact 22 comes into the circuit. Thus a positive potential is applied to both ends of the relay 17 which is thereby deenergized and allows contacts 16 to open. This breaks the circuit to the solenoid 14 of the lowering valve 6, which closes. In the event of a hydraulic or mechanical failure which causes the platform to tilt, the mercury in the lowest switch reaches a contact 23 which energizes a "fail-safe" relay 28. This arrests the platform by opening contacts 29 thereby de-energizing all the solenoids 14 and closing all the valves 4, 6.

Title: An improved variable speed and reversing gearing
IPC: F16H3/68
Filed: 1921-05-11
Abstract: 183,951. Hatcher, E. C., and Rooke, T. May 11, 1921. Variable-speed toothed gearing comprises intermediate shafts 34, 35 driven through a worm- and-wheel pair 36, 37 and driving through a like pair 41, 42 and connected by alternative trains brought into action by clutches. The driving and driven shafts are 31, 32 respectively. In a form shown in Fig. 5, the alternative trains are spur and are operated by double clutches 40 upon the shaft 35. In a form shown in Figs. 1, 2, the alternative trains 38, 39 are worm-and-wheel, and the shafts 34, 35 cross each other at right angles. Four clutches 40 on the worm-wheel shafts 35 are brought into action singly to yield three speeds and reversed driving, being operated through selector bars 43 from a lever 45 moving in a gate 46. In a form shown in Fig. 4, the worm-geared crossed intermediate shafts 34, 35 are carried in a revoluble frame 33a. Means for reversing the drive are provided independently of the four clutches 40, so that four speeds in either direction are obtainable in addition to a solid drive. The clutches 40 are operated by two grooved collars 70, and the reversing-gear by a lever 65. The terminal worm-wheel 42 is loose upon an extension 33b of the carrier 33<a>. The wheel 42 has two clutch members 55. 62 and the extension 33b one member 63. A clutch sleeve 57 has a sliding connection 64 with the driven shaft 32. As shown, the wheel 42 is locked by a sliding member 51, and the shaft 32 is driven from the carrier 33<a> in a direction which may be the same or not as that of the shaft 31. When members 51, 57 are slid to the left, the member 51 clears the wheel 42 and by dogs 52 engages dogs on the carrier. The member 57 releases the carrier and engages the wheel 42 only, yielding a reversed drive. The solid high-speed drive is effected when the members 51, 57 are moved to the extreme right, the wheel 42 and carrier being both clutched to the shaft 32. The locking member 51 may be held against rotation by springs, or by a magnetic or liquid-circulation device.

Title: Improvements in Vibrating Decelerating Relays for Controlling Electric Motors.
IPC: H02P3/12
Filed: 1918-08-20
Abstract: 128,459. Breeze, V., and West & Co., A. Aug. 20, 1918. Systems for continuous-current motors only.- In vibrating decelerating relays for use with electric motors to prevent excessive voltage rise when resistance is suddenly cut out of the shunt field circuit, the operating-coil D of the relay is arranged in shunt tb the field circuit F and its variable resistance R, the relay contacts C, C' being normally closed, and short-circuiting a part of the field resistance. A coil D<1> in series with the armature opposes the shunt coil except when the motor runs as a generator, and at starting and speeding up ensures in action of the relay. If when running at high speed a part of the field resistance is suddenly cut out, the resulting voltage rise energizes the coil D sufficiently to open the contacts; the consequent diminution of voltage and the inclusion of resistance in the coil circuit causes the closing of the contacts and results in maintaining the relay in vibration until the motor speed has adjusted itself tn the increased field strength.

Title: Production of conjugated diolefins
Inventor: HABESHAW JOHN
IPC: C07C2/86
Filed: 1958-04-29
Abstract: Isoprene is produced by catalytically condensing formaldehyde with isobutene in a vapour phase mixture of isobutene and butene-1, which latter remains unreacted, distilling the product to obtain unreacted isobutene and butene-1, overhead and a bottoms fraction containing isoprene which is recovered.  The starting material may be a C4 cracked petroleum fraction preferably containing at least 20% isobutene, not more than 10-15% butenes; less than 5% of butadiene and containing butene-2 in addition to butene-1.  Recycle of unreacted material is controlled to prevent build-up of butene-1. The process may be combined with an isomerisation process which converts butene1 to butene-2, the initial material either being introduced into the condensation reactor, usually when butene-2 is absent, or the isomerisation reactor if butane-2 is present.  In the former case all or part of the overhead from the distillation following the condensation reactor is isomerised and the effluent distilled to separate butene-2, the overhead being recycled to the condensation.  In the latter case the whole overhead from the distillation following the condensation may be recycled to the isomerisation or part may be recycled to the condensation direct or to the distillation following the isomerisation.  The isomerisation may be effected as described in U.S.A. Specifications 2,403,672 and 2,428,516, preferably at below 200 DEG C. e.g. using mineral acids which may be supported on alumina, kieselguhr, bauxite or porcelain chips or over silica-alumina, surface-active earths, magnesium oxide, activated brucite, activated magnesite, reduced nickel or cobalt, black chromium oxide or tungsten/nickel sulphide.
