Title: Improvements relating to asphalt compositions
IPC: C08L95/00
Filed: 1963-04-01
Abstract: A composition comprises asphalt in which is dispersed 0.1 to 40% by weight based on the composition of an ethylene/vinyl acetate copolymer containing 5 to 40% by weight, based on the copolymer, of vinyl acetate.  The composition may be made by mixing asphalt and the copolymer at 300-330 DEG F. in a sigma blade mixer or with high speed agitation. The asphalt used may be natural, derived from crude oil, or oxidized. The composition has a penetration ratio greater than that of the un-modified asphalt.

Abstract: 666,290. Gas turbine plant. LUCAS, Ltd., J. May 9, 1950. [May 16, 1949] No. 12952/49. Class 110(iii). [Also in Groups XXVII and XXIX] Liquid fuel controlling means for a gas turbine engine comprises a fuel controlling device responsive to blower air pressure and valve means movable between two positions for enabling either the full delivery pressure of the blower or a predetermined part thereof to act on the fuel controlling device. As shown, burners 2 are supplied by a swashplate pump b adjusted by a servo-piston h responsive to pressure in a chamber above the piston, this pressure being regulated by a hinged leak-off valve o actuated by a diaphragm w subject to the pressure drop across a throttle z in the supply conduit to the burners. A movable member 3 of the throttle is adjusted by a bellows 17 which, according to the position of a valve member 14, is exposed either to full blower air pressure communicated thereto through a passage 13 from a conduit 10 through which the blower air is passed, or to a predetermined part only of such pressure communicated through a passage 19 from a Venturi 9. The valve member 14 is actuated by pistons 6, 7 subject, through passages 8, 11, 12, to the pressures before, after, and at the throat of, the Venturi, so that the valve member 14 is actuated automatically at a predetermined blower air pressure. Modifications are described in which the connections to the pistons 6, 7 are varied, and in another arrangement only one piston is employed. In a further modification, the valve member 14 is actuated by a diaphragm subject to the pressure rise across the blower. Specification 577,016, [Group XXIX], is referred to.

Abstract: 721,102. Tool grinders. FLUCKIGER, W. May 12, 1953 [May 31, 1952], No. 13246/53. Class 60 A machine for grinding cutting tools such as turning tools, milling cutters and the like comprises a frame 1 and two movable parts carried thereby. The first movable part carries the tool to be ground and comprises an angular shaped support 2 one of the arms of which is vertical and slides in a guide integral with the frame and arranged on the inside thereof, whilst the other arm is horizontally arranged above the frame. The support 2 is vertically adjustable by a handwheel 7. A tool carrier 5 is mounted on the horizontal arm 2 and is movable therealong by a handwheel 6. The carrier carries a vice 9 into which the tool 10 to be ground is fixed; the vice has a semi-cylindrical box fitting a correspondingly shaped recess in the carrier, enabling the tool to be pivoted around an axis cross-wise to the tool and parallel to the direction of movement of the carrier 5. The second movable part comprises the grinding head 3 which consists of an electric motor 22 driving, through a belt, a grinding wheel 11 mounted on a spindle of the expansible type to facilitate changing of the grinding wheel. The motor, spindle and transmission are enclosed in a casing provided with ventilation slits. The grinding head is mounted so as to be pivotable about a horizontal axis y-y on the upper end of the vertical arm of an angular piece 12, the end of the horizontal arm of the angular piece being fixed to the upper end of a piece mounted in a vertical groove in the frame and also adopted to turn about a vertical axis x-x which intersects the axis y-y. The movements of this sliding and rotating piece and consequently of the grinding head 3 may be obtained either manually by the operation of handwheel 8 or selectively either by hand or by means of a motor located inside the frame. An electromagnetic coupling arrangement acting on the members of a transmission mechanism placed between the handwheel 8 and the motor on the one hand and the sliding and rotating piece on the other hand makes it possible to effect either vertical movement or angular movement of this piece. Adjustable stops are provided to limit the extent of these movements. Scales 16, 17 are provided for determining the angular movements of the head 3 about the axes y-y and x-x.
Patent GB-132491-A (GB)
IPC: F41A25/02
Abstract: 132,491. Schneider et Cie. Sept. 10, 1918, [Convention date]. Recoil apparatus. - Relates to means for regulating the length of recoil in brakes of the kind having a fixed or recoiling cylinder provided with an axial control rod, working within the hollow brake - piston rod. and a valve for moderating the run-out. According to the invention, shown in Figs. 6 and 8 applied in conjunction with a recoiling brake cylinder A, the liquid passes the piston E by way of short tapered grooves a in the cylinder wall and long tapered grooves b in the control rod B. By rotating the rod D of the piston E, or, as shown, the control rod B, passages c in the piston may be registered wholly, in part, or not at all, with the grooves b, thus causing a long recoil, one of intermediate length, or a short recoil, respectively. The first position is shown in Fig. 6, and the last in Fig. 8. The rotation may be effected by hand or automatically by the means described below, in accordance with the gun elevation. An arm B<2> on the rod B engages in a box g on a slide G which is movable longitudinally in a guide h on a member H transversely movable in a bearing F<1> in the cradle F. The member H carries a roller H<2>, and is pressed outwards bv a spring H<1>. When the gun is elevated, the roller contacts with a guide J on the gun-carriage cheek I, and rocks the control rod B into the cut-off position, as shown.

Abstract: 1,098,745. Cooling reactors. BABCOCK & WILCOX Ltd. March 29, 1965 [March 28, 1964], No. 13280/65. Heading G6C. In a marine nuclear reactor the steam generating heat exchangers are mounted within the spherical pressure vessel partly above the core. The water coolant and moderator is circulated upwards through the core, to the heat exchanger, and then downwards between the core and the pressure vessel inner surface, by convection. The coolant pressure may be above the critical value. The heat exchanger is protected by a neutron absorptive shield interposed between it and the reactor. The coolant flow through the exchanger is divided into two parts, the cooler of these, which flows through the pre-heater section of the exchanger, is directed towards, and cools, the upper cover of the pressure vessel.

Title: Drawing filaments, films and like articles
Inventor: JONES ROBERT EDWARD
IPC: D02J1/22
Filed: 1954-05-07
Abstract: A process for hot drawing one or more filaments, ribbons or films made from linear polyesters to at least twice their original length, comprises heating the formed polymer by allowing one or more narrow streams of hot fluid, particularly gases or vapours such as steam, to impinge on the polymer at the same time as the polymer is being stretched.  If desired, the filaments may be subjected to a second heating by passage, for instance, through a steam bath either before or after the heat-treatment by the stream of hot fluid.  In a preferred embodiment, the apparatus to be used consists of feed and draw rolls, the latter revolving at at least twice the peripheral speed of the former and one or more jets positioned between the rolls and close to the line of travel directing steam at 100 DEG  C. transversely across the filaments, ribbons or films.  If two or more jets are used, the jets are not placed opposite each other. Frictional drag may, if desired, be produced on the rolls or capstans of the draw frames by either spraying them with water, or, preferably, with a solution of a wetting agent, such as a 0.5 per cent solution of "Subrol" (Registered Trade Mark), sprayed at the rate of 125 c.c./minute.
