IPC: E04G11/28
Filed: 1954-11-20
Abstract: 800,301. Casting concrete structures. WILLIAMS, C. I. Nov. 20, 1954, No. 33657/54. Class 20(2) A method of building a concrete structure by the pouring of successive lifts of concrete, comprises non-removably casting one pigtail anchoring member having an externally threaded end portion in the last poured lift, and when said last poured lift has set, disconnecting a concrete form from a similar pigtail anchoring member cast in the previously poured and set subjacent lift, and raising the form to a position for pouring the next superjacent lift where it is secured to said one pigtail anchoring member cast in said last poured and set lift. In the casting of a concrete block 13, Fig. 1, such as is used in dam construction, a lift 15 is moulded using shuttering 10 secured by she-bolts 21 to pigtail anchors 18 set in the previously cast lift 14, and when the lift 15 has set, the shuttering 10 is elevated by means of hoists 22 into a position for pouring the next lift and is secured to the lift 15 by she-bolts 21 engaging pigtail anchors 18 in the lift 15. The pigtail anchors 18 are supported, during the moulding of a lift, by dummy she-bolts 31 at the upper part of the shuttering 10. The dummy shebolts are removed after setting of the concrete, and the screwed ends of the pigtail anchors 18 are then accessible to shebolts 21 used to secure the shuttering for pouring the next successive lift. The level of the shuttering is adjusted by means of jacks 26. A hoist 22 consists of an A frame 37, 38, Fig. 3, carrying winding mechanism 47 for a cable 53 whichpasses over a sheave 42 at the apex of the A frame to a hook 54 engaging a hanger 64 on the shuttering. The A frame is secured by means of an anchor in the form of a hair pin 56 or pigtail 61, which is set in the previously cast lift, and by a cable 46 or rod extending therefrom to the apex of the A frame. Hardened pointed members 59 at the lower ends of the A frame penetrate the upper surface of the lift. The hoists 22 are removed when the shuttering has been secured by the she-bolts, and the concrete is then poured. Specification 800,302 [Group I] is referred to.

Abstract: 607,311. Turbine power plant. SOC. CIVILE D'ETUDES THERMO-MECANIQUES. Dec. 14, 1945, No. 33942. [Class 110 (iii)] In a power plant comprising a number of free-piston air compressors driven by supercharged internal-combustion reciprocating engines also of the free-piston type and in which at least one of the compressors is used to supercharge the reciprocating engines and the remainder are connected in series and used to supply combustion air to a boiler at a pressure equal to that of the steam, the exhaust gases from the reciprocating engines are used to heat in a heat exchanger the combustion air before its use in the boiler and are then passed to a low-pressure stage of a gas turbine, the highpressure stage of which is fed by the combustion gases from the boiler and the steam from the boiler is used to feed a condensing steam turbine, the condensate from which is returned to the boiler. In the plant shown, the boiler 7 supplies steam and burnt gases at equal pressures to the turbines 8, 9 and is supplied with pressure air by a bank of free-piston air compressors 1<1>, 21, 3<1> driven by supercharged internal-combustion free-piston reciprocating engines 1, 2, 3. The compressors 1<1>, 2<1>, 31 are arranged in series, the air being cooled during compression in coolers 4, 5, and heated in an heat-exchanger 6 by the reciprocating engine exhaust gases. The compressor 0<1> is used to supercharge the engines 0, 1, 2, 3 and the exhaust gases after passing through the exchanger 6 are passed into a low-pressure stage of the turbine 8. Part of the condensate from the turbine 9 passes through a cooler 11 before entering the intercoolers 4, 5 and part passes through the feedwater heaters 10. The cooling water leaving the coolers 4, 5 passes through the cooling jackets of the engines 0, 1, 2, 3 where it is converted into steam and then used in a lowpressure stage of the turbine 9. This steam may be superheated before use in the turbine 9 by a special circuit through the boiler. A solid fuel such as powdered coal or a gaseous fuel such as blast furnace gas or natural gas can be burnt in the boiler.

Title: Two-position mechanism
Inventor: UNDERDOWN PERCY JAMES
IPC: H01H13/56
Filed: 1964-08-21
Abstract: 1,071,524. Releasable-fastenings. A. F. BULGIN & CO. Ltd. Nov. 10, 1965 [Aug. 21, 1964]. No. 34313/64. Heading E2A. [Also in Division H2] A two position mechanism comprises a member 9 mounted to slide in a framework between the two positions, means 19 serving to bias the member into the first position, a plunger 4 having a part 18 which can engage a part 17 carried by the sliding member and a latch 26 which can engage with the sliding member, the arrangement being such that when the plunger is depressed initially the part 18 of the plunger engages the part 17 and moves the sliding member 9 from the first position to the second position in which the latch engages with the sliding member, so as to hold the member 9 in the second position upon release of the plunger which returns to the initial position, depression of the plunger a second time causing the plunger to act upon and release the latch from engagement with the sliding member which is then returned to the first position under the influence of the biassing means. In the construction shown the part 17 is a pawl and the part 18 is a notch in the plunger; the plunger is biassed to its initial position by a spring 6 and the latch is biassed by a spring 27 to the position in which it engages a wall of an aperture 25 in the sliding member 9 when the plunger is depressed; when the plunger is depressed for the second time it does not engage the pawl 17 since once the pawl is released by the notch 18 it is pivoted out of the way of the part 18 by the biassing means 19, thus the second depression of the plunger 4 allows it to be depressed enough to engage the latch 26 and pivot it from engagement with the aperture 25 wall; the means 19 then moves the plunger 9 back to its initial position and the spring 6 restores the plunger to its initial position; during the movement of the member 9 to its initial position the pawl 17 engages a bevelled part 23 of the framework which moves it to the position in which subsequent depression of the plunger causes the notch 18 to engage the pawl. The sliding member may have electrical contacts secured to it in such a position that they contact electrical terminals fixed to the framework; alternatively the sliding member can mechanically move an indicator flag.

Abstract: 170,515. Koppers, H. Dec. 6, 1920. Coke ovens.- In an horizontal coke oven with vertical heating-flues fired from their lower ends, the width of the oven is reduced from the bottom upwards to correspond approximately with the fall in temperature of the heating-gases. The upward taper may be uniform or may be produced as shown by stepping the walls so that the width of the flues increases as that of the oven is reduced. T h i s construction provides a greater wall thickness between the horizontal flue h and the gas space a at the top of the oven, and the heat insulation at this point may be improved by incorporating in the brickwork vertical joints k parallel to the ovens. The roofs of the gas space a and the flue h may be arched. Specification 7664/11 is referred to.
