Abstract: 1341994 Stabilizing hydrocarbons SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 19 April 1971 [5 March 1970] 22940/71 Heading C5E  The fouling of heat exchanger surfaces used to heat hydrocarbon materials is reduced by the addition of hydrazine and/.or one or more alkyl derivatives thereof having less than 5 carbon atoms. 5-50 ppm. by weight of hydrazine is added, in the form of an aqueous solution, to kerosine which is then heated in furnace tubes prior to hydrotreating to remove olefinic, aromatic and sulphur-containing components; the use of hydrazine is compared with the use of a commercial inhibitor consisting of polyisobutylene succinimide.
Patent GB-1387916-A (GB)
Title: Buoyant power plant
IPC: B63B35/44
Filed: 1972-05-16
Abstract: 1387916 Floating structures SANDERS ASSOCIATES Inc 16 May 1972 [24 May 1971] 23010/72 Headings B7A and B7S [Also in Divisions G6 and E1] A power-generation plant is embodied as a buoyant structure intended to be moored at sea and includes a housing in which generation equipment is disposed in such a way that the weight distribution of the structure is such that it will float in an upright position and have high roll stability. As shown, the housing 10 is of hemi-spherical form having a double, compartmented outer wall 10a and an arrangement of internal compartments at levels L1-L7 the lowest of which forms a reactor compartment housing a nuclear reactor 62 and attendant steam-generation equipment. The upper levels enclose other equipment typical of a power plant, as well as a hospital, laboratory and control centre. The flat, upper deck 12 of the housing supports a superstructure 18 having above-deck levels L01, L02 which contain navigational, communications and control instrumentation. The deck also supports a spherical water tank 14 whose contents are intended for use in emergencies arising in connection with the reactor and generation equipment. Above this tank, a further level L03 houses lookouts and radar equipment. The structure has a centre of gravity below its metacentre and is arranged to behave as a pendulum whose natural frequency of oscillation is below that likely to be encountered even in bad sea conditions. The confined volume of level L7 is so large that, even if the rest of the housing 10 becomes flooded, the structure as a whole will still float. Deck 12 can be partially enclosed by a storm shield 98 when necessary. Various arrangements for mooring the structure are described. In one arrangement (Fig. 3, not shown), the housing is supported in gimbals and eyelet connectors are provided at 90 degree spacings around the outer gimbal ring. The connectors receive cables which extend to sea bed anchor pins. In another arrangement (Fig. 4, not shown), the gimbals are replaced by four trunnions; each of four mooring lines has a bifurcate end to provide connections to a pair of the trunnions. In a further arrangement (Fig. 5, not shown), the housing has eye connectors both above and below the water line; each mooring cable is bifurcated to provide a connection to one of the upper eye connectors via an associated pulley and, directly, to one of the lower eyes.

Title: Improvements in or relating to blowers and compressors
Inventor: FRANKEL ADOLPH
IPC: F16K11/087
Filed: 1958-07-18
Abstract: 906,541. Axial-flow blowers and compressors. RICHARDSONS, WESTGARTH & CO. Ltd. July 10, 1959 [July 18, 1958], No. 23144/58. Class 110 (1). A rotary bladed blower or compressor comprises a combined by-pass and throttle valve which is adjustable to full-flow position and various positions of throttle; in its positions of throttle the valve opens two by-pass passages, one of which connects the space upstream of the valve to the inlet of the machine while the other one connects the space downstream of the valve to the inlet. In the blower shown, which is used for circulating gas in a closed circuit, a portion of the diffuser passage is formed by a spherical member 28 which can be turned from the position shown in Fig. 1 to positions in which, as shown in Fig. 2, the flow through the diffuser passage is throttled. Gaps then occur between the member 28 and the upstream part 26 and the downstream part 30 of the diffuser, whereby gas is returned through the gaps to the inlet casing 24 of the blower. When the member 28 is turned into a position at right angles to that shown in Fig. 1, the spokes supporting the inner cone of the member 28 cornpletely block the diffuser passage so that all the gas discharged by the blower is returned to the inlet casing 24 through the gap between the diffuser part 26 and the member 28. Gas can then flow from the inlet casing 24 through the gap between the member 28 and the diffuser part 30 to by-pass the blower and maintain free circulation in the closed circuit.

Title: Feeding bar stock for automatic lathes or the like
Inventor: HILLIER MALCOLM EDWIN
IPC: B23B13/00
Filed: 1957-07-22
Abstract: 827,417. Lathes. AUTOMATION Ltd. July 18, 1958 [July 22, 1957], No. 23176/57. Class 83 (3). Means for feeding stock-bars B through the spindle 1 of an automatic-lathe comprises a divided feed-tube T coaxial with the spindle, and to which the bars are delivered laterally, and a pusher 15 adapted also to withdraw rearwardly and eject the unusable remnant of bar left after machining. Figs. 1-3 show a stock-feed means of the kind described in Specification 728,898, except that a number of carriages 13, Fig. 3, support the movable part 12 of tube T. The carriages slide on rods, one of which, 18, is moved by one of the carriages to operate valves 101, 103 in the automaticcontrol system (not described). A normallyengaged clutch (not shown), controls rotation of the spindle and operation of the turret and tools (not shown), and of the spindle-collet 2, so that the machine stops when the collet opens, the clutch being operated by a lever 8 controlled by the bar-feed. Interchangeable grippers 19 to grip rods of round, hexagonal, &c. section are fixed to the forward end of the pusher 15 and grip the stock when this is held by a stock-stop 7. A ball-bearing 22 on the pusher permits rotation of gripper 19 with the stock, and a stock-ejector 33, retracted by a spring 36, is movable in the pusher to an extent fixed by a slot 35 in the pusher and a pin 34 on the ejector. When the forward-end of the gripper 19 engages the end 57, Fig. 6, of the spindle-collet 2, the pusher is withdrawn automatically, and near the end of this movement the rear end of the ejector 33 engages a fixed stop. Further withdrawal of the pusher ejects the remnant-of-stock 48 through an opening in feed-tube T, or in a breach-tube 12A into which the pusher retracts. Tube T is then opened to receive a new stock-bar, rolled or, as shown, dropped from a magazine. The newbar is then advanced to the stock-stop and gripped by the pusher before being gripped by the spindle-collet and machined. In a modification (Fig. 8, not shown), a ball-bearing is arranged between the end of the pusher and the gripper, which rotates in a self-lubricating bush. The pusher of Fig. 9 is used for ejecting remnants through an opening provided in the bottom of tube T, Fig. 12, by lateral movement of a part 86, or a part 90A, or both. In this pusher the gripper 19 is mounted in a selflubricating sleeve 32, and the ejector 69 is moved by a spring-returned rod 78, which extends through the sloping rearward end 105, Fig. 13, of the pusher. The rod 78 is held by a stop 96 to eject the remnant, and the stop is pivoted to its release position by the end 105 during continued rearward movement of the pusher. For most of its length the feed tube may have a single-piece body with a movable section 91, Fig. 11, to admit the stock, or as shown, a two-part body 89, 90. The ejection section 86 is attached at its ends by brackets 87 to section 91 so that they move together.

Abstract: 1310616 Irradiation apparatus ATOMENERGIKOMMISSIONEN 13 May 1970 [16 May 1969] 23215/70 Heading H5R Matter to be irradiated-e.g. circulating blood-is introduced into a curved duct (5, Fig. 1, not shown) of an irradiation apparatus by use of an elongate band which is pressure-resistant in the longitudinal direction but flexible in a transverse direction, and is provided with holder members for the receipt of tubular containers-e.g. a continuous pipe, or one or more test-tubes-whereby the band may be thrust into the duct with a rapier-like action. The arrangement shown employs a pair of stainless steel bands 7 and 8, the tapered end 14 of band 7 projecting into a slit formed in the curved end of band 8 at the end 12, such that the composite structure is, in Fig. 3, flexible in the plane of the paper. The bipartite handle 9, 10-which may be provided with a scale for indicating the dose for different depths of insertions within the duct-is readily disassemblable to permit the introduction between the bands of a silicone rubber tube 19 which is mounted within and around the holder members 15, 16, and 17 secured to the band 8. The tube may be repeatedly coiled around the pins 16 to give a desired number of passes of the fluid through the  radiation field; a number of different tubes may be mounted between the bands to permit the simultaneous treatment of different fluid samples; the tube may be of rectangular crosssection to spread the liquid out in a direction perpendicular to the radiation; and the portion of the tube which, in use, enters the radiation field may be replaced by a cast unit having ducts formed therein. Reference is made to the possibility of dispensing with the protective band 7.

Signals are produced when the leading and trailing edge of each data mark 10 on a card is sensed, and these signals are combined to represent the data. Corresponding index positions of adjacent card columns are sensed in overlapping time intervals by a common photo-transistor 16 coupled to staggered light guides 13, 14. Waveform A shows the output from a photo-transistor 16, the first two downward transitions corresponding to passage of the leading edge of the card past guides 13, 14. An emitter 34 is triggered by the leading edge of the card to generate pulse trains C, D which coincide with the passage of the leading and trailing edges of index positions in the odd- and even-numbered columns past guides 14, 13. Waveform B, obtained from differentiator 15, is applied, together with its inverse, to pairs of gates in a generator 25, the gates of each pair being enabled alternately by pulses C, D. The outputs of the gates set bi-stable circuits, and a final output pulse is only obtained if both bi-stable circuits of a pair are set, one by the leading edge and the other by the trailing edge of a data mark.
