Title: An improved process for the reactivation of catalyst used in the destructive hydrogenation of hydrocarbon oils
IPC: B01J38/00
Filed: 1930-10-20
Abstract: Catalyst used in the destructive hydrogenation of oils, and not susceptible to sulphur poisoning, is reactivated by separating it from the oil and treating it with hydrogen, preferably at an elevated pressure such as 50 atmospheres or more and at a temperature not above 700 DEG  F.  The hydrogen is preferably free from hydrocarbons liquid at normal temperature: gases from a hydrogenation retort may be used after cooling and scrubbing with oil under pressure.  If unpurified hydrogen is used, the catalyst should preferably be treated with substantially pure hydrogen for a short period before return to the retort.  Catalysts specified are the oxides and sulphides of chromium, molybdenum, tungsten, aluminium, zinc, and of the metals of the alkali, alkaline earth, and rare earth groups.

Title: Improvements in or relating to shock absorbers and other damping means
IPC: B60G17/033
Filed: 1937-11-16
Abstract: 505,221. Controlling shock-absorbers. ARMSTRONG, F. G. G. Nov. 16, 1937, No. 31455. [Class 108 (iii)] Two or more shock-absorbers or other damping means are adjusted by a common remote control which operates on separate hydraulic or vacuum conduits, one for each shock-absorber, to vary the adjustment of all the shock-absorbers similarly, independently of any prior difference of'setting. In the form shown in Fig. 1, rotation of the cam 14 by means of the knob 15 moves the cam follower 13 and the bridgepiece 12 to compress or expand the bellows 11a, 11b, the pressure variations being transmitted through pipes 22a, 22b to the shock-absorbers and used to adjust the settings thereof in, for instance, the manner described in Specification 497,325. In a modification, Fig. 3, differential controls are provided for a pair of groups of shock-absorbers. Rotation ofthe knob 40 controls all four bellows 43a, 43b, and 49b, and rotation of the knob 46 controls the two bellows 49b only. In a further modification, Fig. 5, a vacuum tank 58 is connected by a pipe 57 to one side of a reducing-valve casing 56, a manually adjustable knob 61 controlling the settings of two reducing valves from which run pipes 54 to bellows 50a, 50b, controlling the settings of two shock-absorbers through the links 51. 52.

Title: Improved arrangements for circuit selection
Inventor: KINSEY RONALD WILLIAM STANLEY
IPC: H04Q3/00
Filed: 1955-11-04
Abstract: 816,219. Automatic exchange systems. SIEMENS EDISON SWAN Ltd. Oct. 19, 1956 [Nov. 4, 1955], No. 31634/55. Class 40 (4). In circuit arrangement for choosing a free one of a number of circuits in a group, of the type in which one of a number of similar discharge paths 11-12 is allotted to each circuit, one such path passing current and locking-out the others, each path 11-12 is individually associated with a magnetic amplifier 251 having a low resistance D.C. magnetizing winding (I) connected in series with that path, and having an A.C. winding (II), (III) connected between a source of A.C. 2ACS and an output terminal 2T individual to that path, the current flowing in which depends upon the current flowing in the D.C. winding (I). As shown, each circuit in the group when free causes a direct control current to flow in winding (I) of a switching magnetic amplifier 2S2 individual to that circuit, whereupon a greatly increased A.C. flows in winding (II), (III) of each switching magnetic amplifier affected. This produces across each of the relevant rectifier load resistors 2R4 a voltage in opposition to the positive voltage connected thereto and reduces the potential of the corresponding cathodes 11 to a value lower than that of auxiliary cathode. 13. The glow discharge then transfers from the gap 12-13 to one of the marked gaps 12-11, the voltage drop across 2R1 locks out the other gaps, and the current flowing in winding (I) of 2S1 of that gap produces an output signal at the terminal 2T to initiate selection of the chosen circuit. The output magnetic amplifiers such as 2S1 are arranged so that for the fundamental frequency applied from 2ACS the two sections (II), (III) of the A.C. winding assist in producing flux in the two outer limbs of the core and neutralize each other in the central limb so that in the quiescent condition no appreciable A.C. is induced into winding (I). When the direct current flows in winding (I) alternating voltages of even harmonic frequencies are produced in winding (I), the second harmonic being relatively large, and rectifier 2MR1 provides positive feedback. To restore the circuit arrangement to normal, the control currents of magnetic amplifiers are cut off. In another embodiment (Fig. 1, not shown), 2S2 and its associated circuitry are replaced by a cold cathode tube individual to the circuit concerned which is fired when that circuit is free, and the circuit is restored to normal by raising the cathode potentials of these tubes.

[Also in Division B1] Flat folded filter papers for gas or liquid filters, are made by running a continuous strip 10 of paper through embossing means 27, 28, whereby the paper is compressed along transverse fold lines, and subsequently folding the paper along these lines (Fig. 7, not shown). As shown, the paper is embossed by rollers 27, 28 having alternate co-operating projections and recesses, and the intermediate parts of the rollers do not grip the paper, which is moved by rollers 23, 25. The rollers may alternatively have only co-operating projections, or a single roller may compress the material against a plane surface Rollers 27, 28 could be replaced by one or two vertically reciprocating dies. The fold line spacing may be adjusted by changing the rollers or dies, or by varying their speeds relative to that of the drive rollers 23, 25. The embossed strip 10 receives glued strings (87) for spacing the folds and then passes between further, grooved, drive rollers (79, 83) into a channel (77) of four angle-bars, whose variable spacing offers resistance to the strip, causing it to fold up (Figs. 6-8, not shown). The folded strip is cut into lengths.

Title: Improvements in shock resistant condition responsive instruments
IPC: G01L7/04
Filed: 1963-08-13
Abstract: 1,046,292. Linkwork. DRESSER INDUSTRIES Inc. Aug. 13, 1963 [Aug. 31, 1962], No. 31956/63. Heading F2K. [Also in Division G1] An instrument, e.g. a pressure or temperature responsive instrument, is provided with a shock limiting pivotal linkage between its driving and driven parts, the linkage comprising a pin-andslot connection between a pair of links, a spring normally maintaining the pin at one end of the slot, but allowing the pin to slide in the slot, against the spring bias, if the linkage is subjected to a shock loading in the longitudinal direction of the slot. In a pressure responsive gauge incorporating a Bourdon tube 10, movements of the free end 14 in response to pressure changes are transmitted to a member 20, by way of a bracket 16 and link 18, the member 20 being slidably adjustable by. means of screws 24 on a toothed gear segment 26 pivoted in a shaft 28 and driving a pinion 36 on a pointer carrying shaft 38. The bracket 16 and link 18 are connected by a pivot member 40 moving in an elongate slot 44 in the link 18. A spring 46 holds member 40 in engagement with the top of the slot 44, as viewed in Fig. 1 and sudden movements of the end 14 of the Bourdon tube from the dotted to the full line positions in Fig. 1 will cause flexing of the spring 46, and will prevent shock being transmitted to the pointer movement. Whilst normal movements of the end 14 will be transmitted without relative movement between the bracket 16 and link 18, sudden movements of the end 14 from the full to the dotted line positions in Fig. 1 are allowed for by the connection between the link 18 and member 20 being provided by a member 50 moving in a slot 54. A spring 56 also serving as the pointer return spring holds the member 50 in engagement with the top end of slot 54 as viewed in Fig. 1. Alternatively a spring similar to the spring 46 may be provided between the member 50 and link 18 (Fig. 4, not shown). The springs 46, 56 may be of such strength as to just ensure engagement of the members 40, 50 with the ends of their respective slots and this will eliminate oscillation of the pointer due to pressure fluctuation though stronger springs are used where it is only required to protect the gauge movement against shock loading.

Abstract: 849,350. Jet-propelled aircraft. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Oct. 7, 1958 [Oct. 16, 1957], No. 32323/57. Class 4. An aircraft wing with a trailing edge flap has a jet-propulsion engine mounted on the wing and discharging a jet stream rearwardly from its nozzle over and clear of the wing upper surface, and means operable to deflect the jet stream downwardly to impinge on and spread out laterally over the surface so as to follow the flap upper surface and to leave its trailing edge as a long thin spanwise-extending jet sheet. Fig. 3 shows a section of a wing 2, a spar 9 of which supports by a frame 10 a gas turbine engine 7 enclosed in a nacelle 8 and discharging through a cranked exhaust duct 12 faired in at 8a. Normally, the jet stream 14 extends rearwardly clear of the wing, but for extra lift, a deflector 15 is raised from a recess 18 in the spar 9 to extend across the jet and deflect it as shown. The trailing edge flap 6 of small chord is operable to deflect the jet further as required. The deflector 15 comprises one or more vanes 16, and end plates 19, 20 completing the wing upper surface in the extended and retracted positions. Each vane may be bowed convex downwards. This assists the jet in spreading out spanwise when deflected. The wing may have three such engines mounted in spanwise series, spaced so that the jet sheets formed on deflection are contiguous at the trailing edges. Each engine may have its own deflector, or a single deflector may extend spanwise along the wing. An alternative to deflector 15 comprises a member which is normally retracted but can be raised to contact the undersurface of the jet stream. The upper surface of the member curves downwardly in the rearward direction, so that the jet is induced to follow the surface by the Coanda effect. This surface may also be curved downwardly and laterally, to assist in the lateral spreading of the deflected jet. The engine 7 may be mounted with its rear end raised, to reduce the bending needed in the jet pipe, or may be mounted above the wing. In Fig. 6, the engine is mounted in a nacelle 21 supported above the wing by a strut 22. Jet deflection is effected by an eyelid 23, and the trailing edge flap 25 is of greater chord than flap 6, e.g. 30-35% of the local wing chord. Alternative ways of effecting deflection are by pivoting the engine within its nacelle, or by pivoting the engine and nacelle together. The engines may also drive propellers.
