Title: Improvements in or relating to a pre-stressed beam, column or pile
IPC: E04G21/12
Filed: 1952-02-21
Abstract: 743,406. Concrete structural members; posts. FELDMAN, A. May 21, 1953 [Feb. 21, 1952; March 1, 1952; March 20, 1952; April 4, 1952], Nos. 4583/52, 5444/52, 7175/52 and 8638/52. Classes 20(1) and 20(4). A beam, column or pile consists of reinforced concrete elements 1, 2, 3 held together under compression by a number, preferably two, of high tensile wires 22. The elements are assembled face to face in two groups on two working benches 14 which run on guide rails 17 on rollers 15, 16. The ends 16 may be raised as in Fig. 25, to facilitate the positioning of the wires, by a jack which co-operates with extendible arms to transmit the longitudinal thrust from one group to the other. The jack then presses the ends 16 downwards to bring the groups. into alignment whereby the wires 22 are tensioned. The groups in the aligned position are spaced slightly, the space either being closed by the tension in the wires when the arms are removed, the residual tension being sufficient, or the space is filled with a buffer plate before releasing them. The benches are kept in the horizontal position, against the tendency of the tension in the wires to raise the ends 16, by spring pressed balls 19, which engage the underside of a slot between the rails 17. Alternatively, the wires may be tensioned by a jack acting horizontally on brackets attached to the adjacent ends of the horizontally aligned groups, the rollers 16 remaining on the rails. A buffer plate is inserted before the jack is removed. Preferably a mild steel rod, which may later be removed, is tensioned, in a groove 4 along the back of the beam to prevent it bellying out. The elements 1, 2, 3 are rebated and grooved at 4 and 6 and the end elements 2 have metal anchoring plates 9. The thrust transmitting elements 3 may be specially reinforced or fitted with apertured thrust plates 11 to take actuating pins of the jack. The rebates and grooves may be grouted with cement or other fireproof material to cover the wires and to give the cross section of the structure a regular outline.

Title: Improvements in and relating to transverse driven bodies
IPC: B64C23/00
Filed: 1932-02-16
Abstract: 383,821. Aerofoils, propellers, and sails. ZIEGLER, J. F., 2, Schwarzenbergplatz, Vienna. Feb. 16, 1932, No. 4630. Convention date, March 27, 1931. [Classes 4, 114, and 115.] Transverse driven bodies such as aerofoils, sails, and turbine blades, which are designed to produce a reaction inclined to the direction of motion and which have a conducting passage extending from the pressure side of the surface to the suction side are formed with means for reversing the direction of fluid flow in the passage between an inflow slot of which both edges lie within the outline of the bottom surface and an outflow slot situated in the apical or main zone of the suction surface, such means taking the form of a C-shaped passage, whereby the suction stream first travels forwardly, then is reversed backwardly and leaves in the apical or main zone. This passage may be formed between a main transverse driven body or surface and a frontal body which forms in combination with the main portion, a body having a streamline contour. As applied to an aerofoil, Fig. 1, a lower inflow slot 1 communicates with an outflow slot 2 in the main zone 4 of the upper surface adjacent to apical zone 3. Between the slots is a direction reversing passage 5 having a nozzle-like constriction 6 opening into a larger space where the passage bends round. The inner wall 9 of the conducting passage is reflexly curved and further intake slots 10 may be provided. The slot opening may also be covered with a pervious material. In a modification several outflow slots are employed between normally closed resilient hinged tongues so that the slots which are most effective at any time will open. In a modification, Fig. 7, lower slots c<1> are controllable by springs or by non-automatic means such as those shown. In a still further modification, the wing surfaces are constructed with overlapping resilient scales between the edges of which the air passes. As applied to a mainsail 11, Fig. 2, the sail is secured to a mast 12 and is provided with an air-gap or with openings 13 for the passage of air. At either side of the mast and tangential to it are auxiliary surfaces 14, 15 which overlap the mainsail and are separated therefrom by leech ropes 16, 17 or struts. The surfaces 14, 15 extend past the passages 13 and thus form intake and outlet slots according to the direction of the wind. The air flow through the gaps 13 may be made smoother by sewing in a curved piece 18 of sailcloth or by the employment of a hollowedout rotatable mast as shown in Fig. 3, which Figure also shows the sail subjected to the action of the wind.

Title: Mechanism for controlling the lateral adjustment of tool units of a track maintenance machine
IPC: E01B27/16
Filed: 1972-02-01
Abstract: 1337513 Railway track maintenance machines FRANZ PLASSER BAHNBAUMASCHINEN INDUSTRIE GmbH 1 Feb 1972 [19 Feb 1971] 4655/72 Heading E1G [Also in Division G3] A tool unit of a railway track-maintenance machine is moved laterally and/or pivotally on the chassis of the machine by means responsive to a rail sensor while the machine is in motion, so that correct relative position of tool and rail is maintained to prevent damage when the tool is lowered, e.g. for compacting ballast. The sensor may comprise a feeler actuated potentiometer but preferably is an inductive switch 15, having contacts which are operated when the field of a permanent magnet is sufficiently disturbed by the presence of the rail. A sensor is provided on each side of each rail, spaced to provide a "dead band" to prevent too-frequent operation, and for machines designed for points and crossings, further sensors, more widely spaced, may alternatively be used when required. On such machines, tool units for each rail are individually controlled, but as shown both units are controlled as a pair. The sensors operate electro-hydraulic valves, via amplifiers if necessary, controlling hydraulic actuators 14 or control electric motors which drive a lead screw type actuator. Similar sensors in the same housings may detect rail supports and stop the vehicle for a maintenance operation when actuated. The machine also has rail lifting and aligning tools, measuring wheels and a wire or optical datum line (11) (Fig. 1, not shown).

Title: Thermo-plastic yarns and method of processing them
IPC: D02G1/02
Filed: 1956-02-17
Abstract: Synthetic thermoplastic yarns, such as those made from polyamide, polyester and polyvinyl fibres, are submitted to dry heat in a twisted state, at a temperature sufficient to enable the molecules to adapt themselves to the twisted formation of the yarn, whilst held under tension to a degree sufficient to render the yarn substantially completely elastic.  The twist in the yarn is preferably applied by a false-twist device and the yarns may exhibit crimp or bulk effects. Staple fibre or continuous filament yarns may be treated.  If the process is applied to monofilament yarns, useful active and latent <PICT:0834552/IV (a)/1> torsional forces are imparted and delustering takes place.  Plied yarns may be processed.  One processed yarn may be plied with an unprocessed yarn and the plied yarns may then be processed together.  The unprocessed yarn may be non-thermoplastic, such as of cotton or wool.  Incidental to the processing, yarn may be dyed or sized by passing it under a roller rotating in a liquid bath, the dye being developed as it passes through the heating zone or the size being dried.  The apparatus employed may include a dye applicator 95, tension device 11, thermostatically controlled heater 10, false-twist spindle 2 and a frictiondriven take-up spool S. Specification 803,105 is referred to.
