Title: Improvements relating to diesel engines with overhead valves
IPC: F02F1/32
Filed: 1953-03-03
Abstract: 732,856. Diesel engines. SANDERS, A. F. March 23, 1954 [March 3, 1953], No. 5833/53. Class 7(3). In an air-cooled diesel engine with a detachable cylinder head 13, Fig. 2, and two overhead valves 27, 28 for each cylinder 11, wherein the piston reciprocates as near as possible to the cylinder head, the arithmetic sum of the diameters of the valve heads (plus the necessary clearance between the heads) is large enough to be of greater width than the cylinder diameter, the cylinder being recessed 29 to allow the valves their full lift. The combustion space, including a part-spherical chamber 17, Fig. 1, and an interconnecting recess 18, is offset to one side of the cylinder with its centre lying on a diametrica line of the cylinder which is substantially a right-angles to the common central plane of the valves 27, 28, Fig. 2. The chamber 17, Fig. has an orifice 20 for an injection nozzle and the recess 18 opens into the cylinder through a port 25; the valves may have different lifts and be of unequal size. The compression rings 31 are so disposed in the piston that at T.D.C. they are located substantially centrally in the upper cylinder end 24. The Provisional Specification describes an embodiment in which the upper end of the cylinder is chromium plated or otherwise treated to resist wear ; a cylinder liner may also be provided.

Title: Apparatus for measurements employing neutron radiation
IPC: H01J47/12
Filed: 1946-02-25
Abstract: 616,544. Determination of hydrogen atom concentration. SHELL DEVELOPMENT CO. Feb. 25, 1946, No. 5839. Convention date, April 10, 1945. [Class 40 (i)] [Also in Group XXXVI] In an apparatus for determining hydrogen atom concentration in a substance, fast neutrons are discharged into the specimen where they are scattered, and converted by collision with hydrogen atoms into slow neutrons, which fall on a test member the material of which is partially converted by impact of the slow neutrons into an unstable isotope, which subsequently disintegrates and emits ionising particles which are detected and counted, the number emitted in a given time being proportional to the slow neutron emission and to the hydrogen atom concentration in the specimen. In Fig. 1, a hydrogen-containing fluid is circulated through a metal pressure barrel 3 containing a porous core 1 whose degree of saturation is to be measured. A source of fast neutrons 9 (which may be a radium-beryllium mixture) in a lead container irradiates the core and the fast neutrons are scattered and converted by collision with hydrogen atoms of the fluid to slow neutrons. These bombard a test member (which may be of rhodium, indium, silver, manganese, dysposium) partially converting it to an unstable isotope. The test member comprises the cathode 15 of a radiation detector 17 of the Geiger counter or ionisation chamber type having anode 19, and the counter output is applied through switch 35 to an amplifier having recording and indicating units 25, 26. After irradiation of the core and test member for a prescribed time with switch 35 open, the fast neutron source is removed to a distance and switch is closed. Beta particles emanated by the disintegrating isotope in the test member ionise the radiation detector causing current pulses to pass between the electrodes. The pulses are amplified and counted, the number registered in a predetermined time being proportional to the slow neutron production, which is a function of the hydrogen atom concentration in the core, and consequently of the degree of saturation of the core with the hydrogen-containing fluid. In a modification (Figs. 2, 3, not shown), the test member may take the form of a plate placed adjacent to the core, which after receiving the emergent slow neutrons may be removed to a distance and placed in proximity to a radiation detector with amplifier and indicator. The detector wall may have a window of beta-ray permeable material such as mica supported on a metal lattice. The device may be used for measurements of gas pressure, liquid-level, concentration of a substance in a mixture, presence of moisture, determination of hydrogen in metals, in which hydrogen-containing substances are involved.

Title: Improvements in or relating to devices for automatic transfer of attachment or coupling between relatively moveable members
IPC: F16K3/14
Filed: 1928-02-25
Abstract: 312,615. Mason, H. L. Feb. 25, 1928. R o t a r y disc valves; piston valves; wedging or jamming.-A reciprocating or rotary sliding valve of the gate or full-way type having at least two moving members is provided with means, in the form of sliding bolts, balls, or similar coupling members, for obtaining a rigid connection between one of the moving members and the valve casing during part of the movement of the primary moving member, and to the primary moving member itself during the other part of its movement. In the example shown in Fig. 9 of a rotary double disc valve, the discs 33<1>, 45 are wedged outwards into close contact with the seatings in the closed position, as shown. In the first part of the opening movement of the spindle 48 the central wedgemember 39 moves relatively to the valve discs and carrier-yokes 37, 37', the latter being secured to the casing by the balls 43, 43<1> which engage recesses in the valve casing. This relative movement releases the wedging action of the member 39 whereupon the balls 43, 43<1> move into recesses in the wedge member 39 and release the carrier yokes from the casing. The carrier-yokes 37, 37<1> valve discs, wedge member 39, and spindle 48 all now move in unison until it is desired to close the valve, whereupon the reverse action of the coupling members and wedge member takes place. A similar arrangement of locking-balls &c. is shown applied to the loose floating follower-member of the piston valve described in Specification 277,075. thus dispensing with springs. According to the Provisional Specification, the above coupling-arrangement is applicable more widely as a means of releasing a member which had been attached to another and attaching it instead to a third.
