Title: Improvements relating to induction electron accelerators
IPC: H05H11/00
Filed: 1952-02-08
Abstract: 695,688. Magnetic field measurements. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 8, 1952 [Feb. 14, 1951], No. 3424/52. Class 37. [Also in Group XL (a)] An orbital induction electron accelerator has a cyclically varying magnetic field acting upon charged particles injected into the field and then deflected from the field, the energy level of the particles being measured by apparatus which is rendered operative when acceleration commences and inoperative when the particles are deflected from the field. The accelerating field is provided by solenoids 11, 12, Fig. 2, energized with A.C. from a source not shown; when the A.C. passes from a negative valve through zero to a positive valve, the change in flux in an easily saturated core 17 produces a positive pulse which actuates a pulse generator 20 to excite an electron gun 13 and inject electrons into the chamber 5 for acceleration by the magnetic field; the electrons are deflected from the accelerating field by windings 21 . . . 24 energized by a pulse generator 25 actuated by a pick-up coil 26; normally, the electrons are deflected from the accelerating field when the field is at its positive maximum, but it may be desired to deflect them after the accelerating field has passed its positive peak value, and the invention enables the accelerating field to be measured over the whole period from injection to deflection of electrons. The negative pulse developed at 18, Fig. 2, when the electrons are injected is applied at 18, Fig. 3, to render valve 41 non-conducting and valve 42 conducting, so that valve 48 draws more current and valve 49 draws less current, and hence point 39 increases in potential while point 40 decreases in potential; the diodes 32 ... 35 conduct and meter M registers the current developed in winding 29, Fig. 2, by the accelerating field. When the electrons are deflected from the field by a pulse from generator 25, a negative pulse is developed over current transformer 27 at 28 and applied to 28, Fig. 3, to render valve 42 non-conducting and valve 41 conducting so that the potential of point 40 is above that of point 39 and the diodes are non-conducting, the meter ceasing to register. The deflection of the instrument M is proportional to the average current through it, which, at constant frequency is proportional to the time integral of the current flowing through it, i.e. to the time integral of the voltage induced in coil 29 or the change of flux during the acceleration period, i.e. to the final energy of the electrons. Specifications 574,812 and 585,992, (both in Group XL), are referred to.

Title: Cooling rotary piston engines
IPC: F02B55/04
Filed: 1962-01-31
Abstract: 984,773. Rotary-piston internal combustion engines. NSU MOTORENWERKE A.G., and WANKEL G.m.b.H. Jan. 31, 1962 [Feb. 10, 1961], No. 3595/62. Heading F1F. In a rotary piston I.C. engine working on a four-stroke cycle and of the trochoidal type, the piston 7, Fig. 2, is formed with a plurality of internal chambers 13 communicating through coolant supply ducts 14, Fig. 1, with an annular reservoir 15 in the piston fed from a duct 16 and through drain ducts 17 with a coolant collecting cell 18 formed in the piston. The reservoir 15 is sealed on its outer periphery by a resilient seal ring 22 carried by the piston and the ducts 14 open into the chambers 13 at the outer radial extremity thereof. Radial ducts 19a formed in a fixed plate 19 collect the coolant from the cell 18 and pass it to return ducts. During the rotation of the piston and its planetary movement around the inner contour 8 of the housing, the acceleration forces change in direction so that the coolant is first forced through the ducts 14 into the radially outward portions of the chambers 13 and thence inwardly to pass out through the drain ducts 17. In a modification, the collecting cell may be formed in the end face of the housing instead of in the piston. A seal ring similar to the seal ring 22 is then fitted on the other end face of the piston to prevent the leakage of coolant between the piston and the adjacent and face of the housing. In a further modification, a further seal ring radially outwards of the seal ring in the said other end face of the piston is fitted. Any coolant passing the inner seal ring is then collected in an annular piston chamber and returned to the collecting cell. Specification 893,938 is referred to.
