IPC: B21C1/06
Filed: 1972-12-21
Abstract: 1364809 Drawing TECHNOFIL SpA 21 Dec 1972 [31 Dec 1971] 59149/72 Heading B3P The drawing drums 14 of a wire drawing machine are arranged in a spiral configuration. Wire 15 is drawn by the drums 14 over one of a number of guide pulleys 17, 17<SP>11</SP> arranged at the corners of the machine and through dies 16 positioned between the drums 14. The angle subtended at the cente of the drum 14 by the points at which the wire 15 contacts and leaves the drum 14 decreases progressively from one drum to the next, e.g. from 340 degrees down to 300 degrees. After passing through the final die 18, the wire 15 is annealed and coiled. Each drum 14 is slightly displaced to one side relative to the immediately preceding drum to permit alignment of the wire 15 with the die 16. Each drum 14 is mounted on a shaft 19 having gear wheels 23, 24 which are connected by cogged belts 25 to the gear wheels of the adjacent drums. One of the shafts 19 is driven by an electric motor to cause rotation of all of the drums 14.

Title: Improvements in or relating to high speed bias weaving and braiding
IPC: D04C1/06
Filed: 1968-12-30
Abstract: 1,202,000. Braid. PRODUCT & PROCESS DEVELOPMENT ASSOCIATES Inc. 30 Dec., 1968, No. 61711/68. Headings D1C and D1K. A braiding machine comprises a series of guides 22 through which yarn passes from a supply and which are movable in a zig-zag path to braid the yarns together. In an arrangement the guides 22 are each arranged in individual blocks 23, Fig. 5, mounted as a whole in a frame. A series of cams 27, 31 driven from a drive shaft 36 impart vertical and horizontal motion to the blocks, such that the yarns extending from them to a feed roller are braided together. The yarns are fed at right angles to the back of the blocks to prevent them becoming twisted on the feed side. Alternatively after each portion of braiding the braid is held by the feed roller and the guide blocks given reverse motion to effect back twisting. Braiding of the next portion is commenced when the yarns are free. Instead of blocks the guides may be tubes which are similarly operated by blocks or are carried in raceways controlled by switches to manipulate the guide links to cause the yarns to become braided. The briad can take various forms and configurations.

Title: Methods of reactor power determination in nuclear reactors
IPC: G21C17/00
Filed: 1979-01-31
Abstract: A method for rapidly and accurately generating an output signal (8) corresponding to the power of a nuclear reactor comprises generating out-of- core neutron flux reactor power signals (2) at different time intervals and utilising predetermined relationships therebetween to adjust a more accurate thermal power signal (1) which has a slow response to transient power conditions. By means of a feedback loop (9), a delayed power signal (3) is fed back to a difference unit (5) to generate a signal in proportion to the difference between the neutron power signal (2) and the delayed power signal (3), which signal is combined with the thermal power signal (1) in a summing unit (4) to obtain a value equal to the instantaneous core power then being perceived by thermal sensors but not immediately available due to the time lag of the thermal response. The output signal (8) is used for reactor control, power limitation or safety shut-down. <IMAGE>

Title: Process for producing a combination yarn
IPC: D01H4/06
Filed: 1979-08-30
Abstract: The object of the process is to produce a yarn comprising a core of continuous filament and a sheath of staple fibers. The staple fibers are delivered to a suction surface comprising a perforated collecting surface exposed to relative suction in a suction zone, the fibers being conveyed in a current of air moving virtually at right angles to the surfaces of two counter-rotating friction discs having narrowly spaced opposing faces defining a gap. From the suction zone, the staple fibers are transferred, generally at right angles to the axis of the current of air, into the gap. The continuous filament is united with the staple fibers in the suction zone, and both components are twisted in the gap between the counter-rotating friction discs.

Title: Air-compression direct-injection internal combustion engine
IPC: F02M61/18
Filed: 1979-10-01
Abstract: An air compression direct-injection internal combustion engine having a combustion chamber shaped as a body of rotation arranged in a piston is adapted so that in use a rotational motion is imparted to inflowing combustion air, and at upper engine speeds fuel is deposited, by means of a needle nozzle with controllable cross-section, partly in the form of a film on the wall of the combustion space in the direction of the air motion, whereas during idling and at lower engine speeds and loads direct mixing with the combustion air occurs, the fuel injection pressure at the nozzle bore and thus the speed of the fuel jet being maintained constant or substantially constant over the entire operating range of the engine. The speed of the fuel jet is adjusted so that at nominal rotary speed of the engine it is substantially equal to the swirl speed of the combustion air in the vicinity of the fuel jet, and as the rotary speed decreases the speed of the combustion air is reduced substantially to form a speed difference causing friction between air and fuel. The diameter of the injection orifice is selected in accordance with the ratio of engine R.P.M. between idle and nominal speed.
