Title: Improvements in or relating to wireless reception apparatus
IPC: H04B1/16
Filed: 1919-12-17
Abstract: 159,683. Robinson, J., and Crowther, H. L. Dec. 17, 1919. Receiving systems and apparatus; thermionic detectors; heterodyne receiving systems.-In a wireless reception apparatus of the kind described in Specification 153,690, the intensity of the received waves is caused to vary a resistance connected to an oscillatory circuit. Preferably two local oscillators are provided, beating with each other, and the varying resistance is connected to one of the local oscillators to vary its frequency and thus alter the pitch of the beat note. As shown in Fig. 1, the output circuit of the last low-frequency amplifier 5 is connected by e. transformer 6 through a condenser and grid leak 8 to the grid and filament of a valve 7. The plate-filament resistance of this valve is thus varied according to the intensity of the received signals. Two valve oscillators 10, 12 producing oscillations of slightly differing frequency give a beat note in the telephone 16. The varying resistance 7 is shunted across the tuned plate circuit of one of the oscillators 10, thus varying the frequency of this oscillator and varying the pitch of the beat note. Fig. 4 shows a modification in which highfrequency energy is applied direct to the grid of the variable-resistance valve 19. This valve may be connected to the local oscillators in the manner shown in Fig. 1. As shown in Fig. 4, it is connected in series with the plate battery'20 of the oscillator 21. The incoming energy thus varies the effective potential applied to the plate of the oscillator 21, and alters the frequency of this oscillator and the pitch of the beat note.

Filed: 1945-11-26
Abstract: 601,297. Reinforced concrete; casting buildings in situ. COCKMAN, F. R. Nov. 26, 1945, No. 31870. [Classes 20(ii) and 20(iv)] In the making of a reinforced concrete structure, the reinforcements are formed as hollow members by means of which the concrete is introduced into, and distributed in, the space to be filled. In the Figure, the reinforcement is shown as comprising vertical tubes 1, and horizontal tubes 2 welded together with communicating bores, and subsidiary horizontals 2a. The shuttering is not shown. The tubes 1 are spaced at intervals along the wall shuttering, the bottom ends being sealed off by feet 3 which may rest upon a damp course. The horizontals 2 are spaced in the floor or roof shuttering, and all the tubes have simple openings in their walls, or as shown, branches 4, for the passage of the concrete into the shuttered space. The tubes 1, 2 each have one or more connections 5 for attachment to the concrete supply conduits 6, 6a, 6b, &c. Frames 7, 8 for doors, windows or other permanent fittings such as cupboards, fireplaces and chimneys are incorporated in the hollow reinforcement framework and form part of the shuttering, the attachment shown being by straining- wires 9, or by solid or hollow reinforcement rods 10 which are hooked on to the horizontals 2. The framework itself is cross braced as required by solid or hollow rods 11 or by straining-wires (not shown). The pouring is commenced at the lowest connection 5, and continued at progressively higher connections. The filling can be controlled by dampers or valves in the hollow reinforcements, the valves being left in the framework. The subsidiary horizontals 2a may be used for pouring partitions or for pouring piers 12. Ducts for water, gas, electricity &c. may be incorporated in the framework, and the shuttering, particularly on the inner wall surfaces, may be permanent, e.g. of asbestos sheeting or panels. Similarly permanent floor boards and ceiling panels may be used as shuttering, the floor boards being provided with the necessary air escape outlets. Normal reinforcement rods may be hooked over the tubular frame, or hooked ends of reinforcement rods may be inserted in the branches 4 which themselves reinforce the structure against shear strain where floors join walls. The wall shuttering may be shaped to provide ledges to support floor joists, the ledges being reinforced by rods which are looped around the adjacent horizontals 20. The whole or any appropriate part of the tubular reinforcement may be prefabricated.

Filed: 1922-11-23
Abstract: 203,964. Newman, Ltd., W. H., and Vale, T. H. Nov. 23, 1922. Tobacco pipes.-To prevent entry of dirt &c., the passage in the mouthpiece is adapted to be closed by a rotatable member which can be turned to uncover the passage when required. As shown, the mouthpiece bore 4 terminates in two diverging passages 5 which emerge at opposite ends of a flat face. Midway between these,passages is an integral central screw-pin 6 on which screws an elliptical closure member 7 formed with a flat inner face, so that when screwed home it closes the ends of the passages 5, but when rotated through half a turn it leaves a narrow space 8 for the smoke. The piece 7 corresponds in shape with the end of the mouthpiece and is rounded on its outer side. It may be prevented from becoming completely detached by heading over the end of the screw-pin 6 or otherwise. In the case of a mouthpiece having a single central passage, the closure member 7 mav be formed with a hollow central screw-pin with side exits for the smoke; or the passage may terminate in an externally screwed sleeve, cut away at one side, and engaged by a tapped hole in the closure member. The minor axis of the member 7 is preferably less than the distance between the ends of the passages 5, so that these are exposed for cleaning when the member 7 is rotated through a quarter turn.

Abstract: 759,845. Gas turbine plant. SCHILLING ESTATE CO. Dec. 19, 1952 [Dec. 24, 1951], No. 32274/52 .Class 110(3) A gas turbine plant, for feding combustion products to a consumer, comprising a plurality of constant volume explosion chambers feeding the turbine through a plurality of tap points through which gases are extracted from the explosion chambers for establishing at the rear of the turbine stages a counter pressure decreasing in conformity with the expansion of the gases in advance of the stages has the explosion chambers disposed alongside the turbine housing with the nozzle valves which supply the working fluid close to and in substantially the same radial planes as the stage nozzle and blade assemblies.. The two stage turbine rotor 1, Fig. 1, has wheels 2, 3 with blade rows 4, 5 contained in a housing 6. The turbine is fed with combustion gases from four explosion chambers a, b, c and d arranged around the housing 6. The axes of the explosion chambers are parallel to the axis 11-11 of the rotor 1 and there is almost complete overlap between the axial lengths of the housing and explosion chambers. The housing and chambers may be bolted to each other by flanges, welded to each other or cast as an integral unit. The chambers are enclosed in a cooling jacket 12 and each comprises an inlet section in the form of a venturi nozzle 13 containing an air charging valve 15 and a fuel injection valve 17 built into the valve 15. The chambers are tapped at three points 18, 19 and 20 controlled by valves 21, 22 and 23. The valves 21, 22 are arranged to open so that they pass combustion gases at a pressure above the charging air pressure to the nozzle 24, 28 feeding the rows of blades 4, 5. The valve 23 allows the gases at the air charging pressure to flow to the consumer 39, in this case, a useful power turbine. The turbine 1 drives the charging compressor 38. The valves 21, 22, 23 are controlled so that when one chamber is discharging through the valve 23, another is discharging through the valve 21 and a third through the valve 22. The fourth has all the valves closed. The gases passing through the valve 22 are mixed in a chamber 27 with the exhaust gases from the blades 4 and the exhaust gases from the blades 5 are mixed with the gases passing through the valve 23 in a pipe 34 before passing to the turbine 39. It is also stated that the operation of the valves is so arranged that the fall in pressure in the chambers 18 and 27 and 34 are coincident so that the pressure drop across the wheels 2, 3 remains constant. A number of these gas turbine plants may be used to feed a single consumer or a single plant may be used to feed a number of consumers. In the former cases the plants may be identical or differ in size. Specifications 288,321, 288,322, 315,366 [all in Class 51(i)], 410,049, 419,004, 759,840, 759,841, and 759,844 are referred to.
