Abstract: 1,177,290. Correspondence control systems. R. ROSSELLINI. May 5, 1967 [May 5, 1966], No.21087/67. Heading G1N. An arrangement for the remote control of a zoom lens comprises a control lever mechanically coupled via step-up gearing to a synchro-transmitter electrically connected to a synchro-receiver coupled via step-down gearing to an output shaft and a friction brake 18 acting on the rotor of the synchro-receiver which brake is adjustable to vary the degree of damping. By a suitable choice of the transmission ratios of the gearing (which may be equal) and the moments of inertia of the rotatable components and adjustment of the brake, for example by means of a calibrated spring, the system is arranged to be critically damped. Flywheels may be added to the rotors of the synchrotransmitter and synchro-receiver and further damping, e.g. of a magnetic type, may be provided.

A reverse sequence is followed if the whole anchor or the casing member 12 is to be raised to the surface for re-use elsewhere. The valves and pumps used for controllably ballasting the tanks in the buoyant casing member 12 may be located on that member, or on the legs or deck of the platform 15. The tanks in the casing member 12 may be provided with agitating pumps or stirrers and used for storing drilling mud or crude oil when in position on the sea bed.

Title: Improvements in or relating to Nuclear Reactor Fuel Elements.
Inventor: BURTON WILLIAM ROBERT
IPC: G21C3/20
Filed: 1968-05-06
Abstract: 1,187,929. Fuel elements. UNITED KING- DOM ATOMIC ENERGY. 27 March, 1969 [6 May, 1968], No. 21438/68. Heading G6C. A fuel pin for use in a fast breeder reactor fuel element which includes a cluster of parallel metal-sheathed fuel pins intended for operation at temperatures of at least 700‹ C. has its fissile fuel separated from its metal sheath by an interlayer in which natural or depleted uranium metal predominates. The interlayer may be in intimate contact with the sheath, or alternatively may be bonded to the sheath by a good heat-conducting material such as sodium, or still further there may be a compatibility barrier between the interlayer and sheath where necessary. The interface between the interlayer and fissile fuel may include grooves or depressions on either or both of the interlayer and fuel surfaces so as to provide a measure of voidage. Alternatively, or in addition, the interlayer and/or the fuel can be provided with distributed voidage so that its/their density does not exceed 80% of theoretical. A uranium alloy which does not undergo phase changes within the operating temperature range envisaged (700-800‹ C.) is used for the interlayer, e.g. a U-Mo alloy. The sheath and interlayer may be co-extruded in order to obtain intimate contact between them. The fissile fuel may be mixed UO 2 /PuO 2 , mixed UC/PuC, PuO 2  alone, or PuC alone. Where carbide fuel is employed it is convenient to employ a sodium bond between interlayer and sheath, since sodium is compatible with carbide fuel. Stainless steel may be employed as the sheathing material. U-Mo alloys are not wholly compatible with stainless steel at the operating temperatures envisaged and a compatibility barrier consisting of a thin coating of Al 2 O 3  on the sheath interior or interlayer exterior may be necessary. Alternatively, electroplating with a suitable inert metallic material may be employed. Otherwise the sheathing material may comprise niobium or vanadium.

Abstract: 1330422 Texturing filaments BADISCHE ANILIN-& SODA-FABRIK AG 19 April 1971 [11 Feb 1970] 21474/71 Heading DIF A process for the manufacture of textured filaments composed of synthetic linear materials of high molecular weight comprising subjecting the filaments to a turbulently flowing medium in a location between a filament inter channel and a filament guide channel in which the filaments are heated to a temperature at which molecular re-orientation occurs in the filaments, the flow of medium being such that it guides the filaments through the guide channel and past at the end of the guide channel a point where there is an increase in cross-section causing a suction effect, said point representing the inlet end of a slightly tapered zone having radial orifices extending in the longitudinal direction and through which an ingress of ambient air takes place so as to produce a temperature drop, the length of the orifices and the distance between filament guide channel and the orifices being adjustable to produce resonance in the flowing medium and cause a continuously moving stellate baffling effect to be exerted on the filament thus stabilising the filaments without causing them to adhere to each other. The process is applicable to polyamides, polyesters and isotactic polypropylene, particularly nylon and polyethylene terephthalate. The process may be carried out in the apparatus shown in Fig. 1 wherein filaments 3 enter a chamber 1 at a filament inlet channel 4 and contact a heated fluid medium i.e. air which is fed to the apparatus via the inlet 14. The filaments are then conveyed along the filament guide channel 5 to the chamber 2. This chamber tapers slightly and is provided along its sides with slots 10. This chamber is held in position by a screw 9. The length of the slots may be varied by moving the cylindrical metal element 11. This element may be fixed in position by screw 12.

The corrugations in the members 3, 7, 8 may be of dovetail shape. The compression members 8 have their ends 9, 91 bent in opposite directions to permit welding to the sheets 3, 7. The top member 3 of the framed beam has its ends bent downwardly to form inclined end members 4 having inwardly-directed flanges 5 which are welded to the bottom member 7 and support the framed beam on the lower flanges of the main beams 2. Each flange 5 is inclined to correspond with the inclination of the surface of the Range of the beam 2. The framed beams are so supported that the bottom sheets 7 lie somewhat below the lower surface of the main beams, and each bottom sheet 7 may be so arranged that at one end 13 it falls just short of the flange of the adjacent main beam 2 and at the other end 14 projects under the corresponding beam flange so that adjacent bottom sheets 7 are practically in contact. Diagonal members 10 in the form of thin metal sheets are welded in position between the compression members 8. Concrete 11 is filled in above or against the sheet 3 which constitutes permanent centring, and concrete or plaster 12 may be secured to the bottom sheet 7 either before or after positioning the framed beams. If desired, the framed beams may be of bow-string form.

Heating means 6 is indirectly associated with the strip 4, and operates the relay. Two contacts 8, 8<SP>1</SP> mounted on a spring tongue 7 are made of materials having respectively high wear, and low contact resistance properties and are mounted opposite similar contacts 9, 9<SP>1</SP> on the strip 4. An insulated pin 10 joins the strip 4<SP>1</SP> to the tongue 7 and ensures that changes in the set of the strip 4 due to ambient temperature, do not affect the contact gap, by making a like deflection of the strip 4<SP>1</SP> compensate by moving the tongue 7. In a changeover contact configuration pairs of contacts are disposed on either side of the tongue 7 and are respectively in engagement with contacts mounted on a second spring tongue insulatedly connected to the strip 4, opposite the contacts mounted on the strip 4 as above. The tongue 7 is insulatedly joined to the strip 41.
