Title: Improvements in rotary apparatus applicable for use as a compressor or engine
IPC: F01C11/00
Filed: 1927-07-13
Abstract: 286,148. Iranee, J. B. July 13, 1927. Movable - abutment type ; working-fluid supply; valve-gear; packing drums and abutments; bearings, arangement of.-The outwardly-sliding abutment of a rotary engine or the like comprises a number of relatively slidable plates, the inner ends of which are maintained in contact with the periphery of an eccentric cylindrical piston by mechanical means actuated by a rotary part of the engine. The piston P<1>, P<2> have end members P<1> - - p<4>', extending to the casing and rotating in fluid-tight engagement therewith, supported by bearings B, B<1> which also serve as thrust bearings. The abutment plates G<1>, which may each be cut in two pieces with spring rings inserted in a. circular aperture or be cut as shown in Fig. 7, are assembled in a carrier U with their outer ends bearing on a rocking seat J therein; the carrier U slides in a housing on the casing under the action of a rocking lever L controlled by a cam or eccentric K rotating with the piston. An internal combustion engine arrangement is shown comprising two pistons P<1>, P<2> rotating in a single cylindrical casing 1. One piston compresses the charge and transfers it by a valve controlled conduit D to the other piston chamber where it is ignited. To reverse the engine a second valve V<2> in the transfer conduit is brought into action and the first valve V<1> held out of action, and at the same time the connections of the supply and exhaust pipes to the ports E', O<2> are interchanged. The combustion space is varied by screwing in the plugs which contain the valves V<1>, V<2>. The pistons may be arranged at 180‹ in which case each abutment is actuated by the other piston. With a three piston arrangement the third may be used with steam generated by the heat of the exhaust gases or may be used for the further expansion of the combustion products.

[Class 60] In a machine suitable for grinding all the crank-pins of a crankshaft in one operation, the crankshaft 20 being operated upon is mounted between centres 21, 22 and is rotated at the same rate as a similar crank-shaft 100 mounted on a transversely movable slide 120, the crank-pins of the shaft 100 carrying grinding wheels 51 ... 54 which are driven through belt gearing 75 ... 78, tensioned by idler pulleys 91 .. 94, from an electrically rotated shaft 61. The headstock and tailstock carrying the centres 21, 22 are adjustable on the machine base 11 to which, when in position, they are clamped by bolts. The crank-shafts 20, 100 are driven through worm gearing 135, 136 and 128, 144 respectively by a shaft 137 which is driven through worm gearing in a casing 141 by a shaft 143 normally connected by a dog-clutch 147 to the shaft 61. The slide 120 may be fed by a screw 121 either continuously or intermittently. The screw 121 may be operated by a hand wheel 123 or gearing such as shown in Specification 6784/01, [Class 60]. The grinding wheels are trued successively when worn by rotation in contact with a diamond 162 carried by a rod 161 adjustably mounted in a holder 160 which can be slid on ways 165 on a slidable table 12 by rotating a stud 171 carrying a pinion 167 engaging a rack 164.

Patent GB-579673-A (GB)
Title: Means for pulsing radio frequency oscillators
IPC: H03K3/78
Filed: 1943-11-19
Abstract: 579,673. Pulse signalling. STANDARD TELEPHONES. & CABLES, Ltd. Nov. 19, 1943, No. 19414. Convention date, Nov. 23, 1942. [Classes 39 (i) and 40 (v)] Pulse potentials for exciting a radio-frequency oscillator by application to its anode circuit are also applied to a readily-excitable device such as a spark-gap associated with a resonant radiator, the device emitting radiation and setting the main oscillator into oscillation with a minimum delay. The resulting radiofrequency pulses are thus timed evenly with respect to the applied pulse potentials, and are of even and increased amplitude. As shown, the pulse potentials are generated at 31 and are applied to the anode circuits of a push-pull valve oscillator having tuned anode, grid and cathode circuits 18, 24, 30. The pulses are also applied to one side of a spark-gap 34, the other side of which is connected to a radiating conductor 36 about a quarter-wave long. The conductor 36 quickly bursts into oscillation and by radiation starts the valve circuit into oscillation. The spark-gap may comprise cylindrical carbon electrodes in coaxial relation, supported on axial metal rods which are screwed into metal binding-posts to provide axial adjustment (Fig. 2, not shown). The conductor 36 and the lead from the pulse producer 31 are secured by screws to the binding-posts, which are supported on an insulating base. The invention has particular application in radio detection systems, and in time-modulated pulse systems such as are described in Specifications 511,222 and 523,575.

Abstract: 1399451 Electron multiplier G W BALL 8 Sept 1972 [8 June 1971] 19445/71 Heading H1D An electron multiplier comprises a chain of dynodes mounted on a stack of spacers, of which one is shown in Fig. 3; each spacer is formed of insulating material with a conductive layer 19 formed at each end and a conductive layer 20 along its side forming a resistance connecting the end layers, each dynode being electrically connected to the adjacent end layers of two adjacent spacers. Each dynode may be secured to a plate which is clamped between two of a stack of spacers mounted on a ceramic rod which passes through an aperture 18 in the spacers; the plates may also be attached to a second stack of spacers which are similar but do not have the conductive coatings. The resistance of strip 20 may be increased to a desired value of 1-2 megohms by reducing its area by flowing abrasive particles against it. In a modification (Fig. 5, not shown), each spacer is cylindrical, and in another modification (Fig. 4, not shown) the spacer is elongate with small apertures near the ends for two support rods and a larger central aperture. The input to the multiplier may be ions or photons.

The spindle is rotatably mounted in a structure 7 rigidly supported on a worktable 7 reciprocatable on a bed 1 of the machine by a hand wheel 3 or hydraulic "creep" feed drive to carry the workpiece mounted in a chuck 9 on the spindle past the grinding wheel 5 carried by a mounting 4 on the bed, the axis of the spindle being contained in the vertical plane containing the direction of movement of the worktable. A pinion on the spindle meshes with a rack formed on a crossbar 10 mounted in a slideway in the head 7. The end of the crossbar has a ball and socket connection with the follower 16 which has rollers 17 engaging each side of the arcuate guide member 13 which may be in the form of a sine bar and mounted on a support plate 14 pivotally adjustable on a support 15 of the bed 1. In use, the sine bar is set with a tangent of its midpoint at 45 degrees to the direction of movement of the worktable and the workpiece is set with its axis at an angle to the direction of movement of the table somewhat less than half the cone angle of the workpiece. As the workpiece is moved by the worktable, the rate of rotation imparted to the workpiece by the sine bar decreases, the helix formed on the workpiece having a substantially constant helix angle along its length. In another embodiment, the guide member is in the form of an arcuate slot.

Ammonia or a volatile amine such as diethylamine, triethylamine, diisopropylamine, allylamine or ethylamine is used to provide all or part of the alkalinity in the process in which a single application of liquid to an exposed silver halide emulsion layer develops exposed areas and produces a corresponding reversed image in a receiving element in contact with the emulsion during development, whereby evaporation from the element after separation from the emulsion reduces residual alkali and thereby avoids instability of the image therein. The ammonia or volatile amine may be included with the processing liquid in a sealed liquid-dispensing container of the type described in Specification 684,592, and such container may be introduced between or provided within the silver halide emulsion layer and the image receiving element, whereby the liquid may be dispensed and spread between the layers after exposure by application of pressure to the assembly. The reversal methods of Specifications 703,231 and 714,412 may be used. Example 1 specifies a water solution of sodium carboxymethyl cellulose, diethylamine, sodium hydroxide, sodium sulphite, sodium thiosulphate, hydroquinone, metol and chlorobenzotriazole as processing liquid. Examples 2 and 6 specify similar mixtures using diethylamine and example 5 a mixture in which the only alkali is ammonia. Specification 684,591 also is referred to.
