Title: Improvements in or relating to steam power plants
IPC: F01K3/00
Filed: 1931-07-10
Abstract: 381,924. Power-generating systems; steam turbines. MARGUERRE, F., 32, Augusta-Anlage, Mannheim, Germany. July 10, 1931, No. 19906. Convention date, July 14, 1930. Addition to 359,140. [Classes 110 (iii) and 122 (iii).] In a plant of the kind described in the parent Specification wherein the turbine performance is varied independently of the steam supply by varying the preliminary heating of the feedwater, governor-controlled means are provided which permit, during normal working, variations in performance without variations of steam supply, but which, on reaching abnormal load variations, vary the steam supply. In the construction shown in Fig. 1 wherein preheaters V1, V2, V3 are supplied with bleed steam from points 1, 2, 3, the control is normally effected by adjusting the valve R. On losing the valve R, the condensate passes to the storer S. On opening the valve R, the pump UP being of greater capacity than the pump P, additional water passes from the storer S to the preheaters. To maintain the water temperature, additional steam from a point 4 and supplied through a valve W controlled by a thermostat or pressure regulator is passed to the preheater V3. The governor r controls a valve K which adjusts the valve R through a relay, and controls also, through lost-motion mechanism, a valve Z in the steam supply which valve is opened or closed when the load i abnormally low or high. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an alternative method of control wherein the regulation first affects the steam supply. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in t-squares
IPC: B43L7/02
Filed: 1950-08-10
Abstract: 703,754. Mathematical drawing-appliances. EVANS, W. J. Aug. 13, 1951 [Aug. 10, 1950; March 19, 1951], Nos. 19961/50 and 6553/51. Class 97(3) In a T-square the stock and blade are fitted together for relative sliding movement as well as relative pivotal adjustment and releasable means, e.g. frictional means or wedge means are provided operable consequent upon the sliding movement for permitting or preventing the pivotal adjustment. To this end one or more surfaces on the blade are adapted normally under spring pressure to birid frictionally on a complemental surface or surfaces on 'the stock or a tapered end on the blade' is adapted under spring pressure or manual action to cause intermediate elements to bind frictionally on a surface of the stock. As shown the arcuate bevelled end of the blade 8 is urged by a tensioned spring 12 against a circular chamfered wall 3a of the stock which comprises a base 1 having a part circular recess 3 with a central rotatable boss 5 which has projections outwardly there from two faces parallel with the straight edge of the blade and in rubbing contact with similar faces of a recess or slot 7 in the blade. The cover plate 2 is'fixed to the base 1 and has a recess conforming to the recess 3 in the base 1 so that the blade is maintained in frictional contact with the inner surfaces of both base and cover plate by the spring 12 forcing the blade against the surface 3a and .the inner rim of the recess in the cover plate. Circular holes in the base and cover plate receive discs 1b, 2b fixed at the two ends of the boss 5. These' discs are graduated for reading the angular displacement of the blade. The blade has two straight edges, viz. 8a for drawing lines at angles to the stock g from 0 to 90 degrees and 8b for drawing lines at angles 90 to 180 degrees during which the T-square is reversed. In an alternative construction the tapered end of the blade forces, by wedge action, two segmental frictional elements against the arcuate surface of the stock under the influence of the springs. The stock is formed with upper, lower and intermediate plates with a circular hole through them, the blade passing into such hole through a gap in the intermediate plate. In a modification of this alternative construction the spring is omitted and stops retain the blade in the hole in the stock. Specification 597,020 is referred to.

Abstract: 1,000,998. Spinning yarns. E. BOBKOWICZ. May 21, 1963 [May 29, 1962], No. 20617/62. Headings D1F and D1W. [Also in Divisions B2 and B5] Textured filament yarn is made by extruding a layer of synthetic resin through an extrusion head, stretching the layer longitudinally to orientate the resin molecules, contacting the layer while soft on at least one side thereof with a fibrous web, pressing the layer and web together to form a composite web, slitting the composite web longitudinally into a plurality of ribbons, and twisting the ribbons into yarns. The yarn comprises a continuous core of synthetic resin surrounded by a sheath of fibrous material some portions of the fibrous material being embedded within the core, and other portions extending outwardly from the core, substantially free from resin. In a modification, the fibrous web is replaced, at least on one side of the resin layer, by a layer of paper, powdered pulp-like material, e.g. linters or paper pulp, or metallic foil. The resin layer may be extruded as a continuous film or as a plurality of parallel filaments. The fibrous web may be performed, or may be formed in situ by blowing staple fibres onto the tacky resin layer. The composite web may itself be bonded in the same way by a resin layer to a further fibrous web, to form e.g. a paper layer sandwiched between two resin layers with a fibrous layer on each outer side. After slitting into ribbons, the twisting operation is preferably carried out with application of pressure or heat and pressure to consolidate the ribbons. The resin may be any extrudable thermoplastic or thermosetting material e.g. nylon, polypropylene, polyacrylonitrile, polyethylene, a polyamide, polyacrylate, a cellulose ester such as cellulose acetate, regenerated cellulose, a polyester or a rubber compound. The fibrous web may be formed of e.g. wool, cotton, bast, remie jute, flax hemp or kenaf, sisal, sansiveria, agaive, glass fibres, asbestos fibres, or man-made fibres such as polyamide, polyester or polyacrylonitrile. If the web is preformed, the fibres therein may be randomly or parallelly arranged. In one embodiment, a synthetic resin, melted in chamber 3, is extruded at 5 in the form of a layer 6. Devices 7 for producing aligned fibre webs, feed such webs 8, 9 by rollers 10, 11 on to opposite sides of layer 6. The web is bonded to layer 6 by passage between rollers 12 which are cooled and are rotating at a speed higher than the extrusion rate, to form a composite web or laminate 13, which then passes via guide 14 to slitter device 15. The resulting ribbons 16 are fed to twisting machine 17 containing spindles 18. Yarn packages 19 are deposited in pots 20.
