Title: Apparatus for producing controlled nuclear fusions
IPC: H05H1/14
Filed: 1973-05-25
Abstract: 1387098 Thermonuclear fusion apparatus EUROPEAN ATOMIC ENERGY COMMUNITY 25 May 1973 [29 May 1972] 25121/73 Heading G6P Thermonuclear fusion apparatus (Fig. 1) comprises a reaction chamber 1 having axiallyopposed plasma inlet and outlet 2, 3 each surrounded by three inter connected windings 2a, 2b, 2c and 3a, 3b, 3c spaced symmetrically in the circumferential direction. The inlet windings create a driving field to impart kinetic and thermal energy to the inlet d-t plasma which, having undergone fusion reactions within the chamber 1 possesses surplus energy which is collected by the outlet windings. Within each set the windings may be delta- or star-connected and feedback from the outlet to inlet windings is achieved by interconnecting them in parallel or series. In order to impart minimal rotational energy to the ingoing plasma, the inlet windings may be supplemented by a further set 12a, 12b, 12c (Fig. 4) of opposite hand to the first set 11a, 11b, 11c. A similar arrangement at the plasma outlet recovers rotational energy from the emergent plasma.

Abstract: 467,390. Typewriters. BURGESS, A. F. (Smith & Corona Typewriters, Inc., L. C.) Sept. 18, 1936, No. 25440. [Class 100 (iv)] Keys.-In a type action including a key-actuated lever and a spring- returned universal bar depressible by the lever, there is provided a keytouch varying pressure device depressible by the universal bar and constantly spring-urged towards it, and a manually settable device for varying the returned or at-rest position of the pressure device with respect to the normal or at-rest position of the universal bar, so as to vary the point of contact between the universal bar and the pressure device when the bar is depressed by a key and thereby to regulate the key touch. In a type-lever action of the kind described in Specification 389,395 the key levers 15, carried by links 18, 19 operate type levers 12 through links 13, 17 and sub-lever 14, and a finger 14a overlies, but is normally spaced slightly from a universal bar 29. The bar is carried by arms 30, pivoted at 32 and operates the carriage escapement, and, by a link 40, the ink-ribbon mechanism 38. The spring 41 of the mechanism 38 acts to return the universal bar 29, against a stop, after depression by the finger 14a. The key action is returned by a spring 22. A touch regulator frame 45 is pivoted at 44 and provided with bendable contact lugs 47 underlying the arms 30 of the universal bar. The frame is drawn upwards by a spring 48 and retained by an arm 58 of a bell-crank lever 50. The springy upper end 54 of the lever 50 extends through a notched and numbered slot in a flange 56 so that it can be set to seven positions. In each position the arms 30 of the universal bar engage the lugs 45 after a different portion of their stroke and in one end position they do not engage them at all.

Abstract: 711,979. Spring suspensions. ALFORD & ALDER (ENGINEERS), Ltd. Oct. 30, 1952 [Oct. 31. 1951], No. 25499/51. Class 108(2) A wishbone for a vehicle suspension of the kind in which the chassis is supported from each wheel by a linkwork comprising upper and lower links, one at least of which is of wishbone form, is made with an oil lubrication reservoir extending longitudinally of one or both side members of the wishbone, means for filling the oil reservoir with oil and lubricant - passages between the reservoir and the bearings of the wishbone. In the arrangement shown, a bracket 13 carrying a stub axle 12, is formed with a screw-threaded king-pin 14 which is journalled on a bearing 46 carried by a wishbone 21. The lower end of the bracket 13 is connected through a ball and socket joint to a lower'wishbone 17 A helical suspension spring (not shown) bears on a trunnion member 38 journalled on side members 22 of the wishbone 21 and the upper end of the spring is carried in a spring case which is connected bv vertical tension rods (not shown), to a rigid cantilever extending from the chassis below the lower wishbone 17. A shock absorber 48 is connected between the trunnion 38 and the cantilever. The side members 22 of the wishbone 21 consists of rectangular tubes interconnected by struts 24. 25. The inner ends of the members 22 are each closed by a tubular hub 29 for a bearing bush 30 which is connected by an oil passage 31 in the hub 29 with the side member 22. The wishbone is journalled on pins 47 on chassis brackets 18. AT-member 35 is carried on a cross pin 34 journalled on bushes 33 in tubes 32 at the outer end of the wishbone and the stem of the T-member forms a screw threaded bearing for the king-pin 14. The bushes 33 are drilled at 40 to afford access of oil to the crosspin bearings and the cross pin 34 is drilled to afford access of oil to the king-pin bearing. The trunnion 38 is journalled in. bushes 37 in tubular members 36 on the side members 22, the members being drilled to afford access of oil to the bushe- 37. The outer ends of the tubes 29, 32, 36 are sealed by spun-in closure plates 43. Each side member is provided with an oil filling hole 45. The lower wishbone 17 may be of similar construction to the upper wishbone. Alternatively the lower wishbone may be replaced by radius rods which may incorporate oil reservoirs. In a modification the spring may bear upon the lower wishbone, the tension rods then being unnecessary. In another arrangement, Fig. 6 (not shown), the closure plates 43 are replaced by screwed plugs and the struts 24, 25 by a single strut extending diagonally between the side members.

Title: Optical interferometer
IPC: G01B9/02
Filed: 1972-05-31
Abstract: 1397443 Polarizing interferometer ERNST LEITZ GmbH 31 May 1972 [3 June 1971] 25506/72 Heading G1A [Also in Division G2] A method of measuring linear or angular speed or position change of an object, or optical path differences, by evaluating the change of the interference between beams of coherent light, comprises splitting at 113 a beam derived from a source 111 of coherent light into at least two phase-correlated partial beams, introducing phase or frequency changes dependent on speed, position or path difference in one at least of the beams, at 116 and combining at 113 the partial beams to form a beam which comprises partial beam components in individual mutually complementary states of polarization. Two signal beams each containing components of both partial beams are derived, by divider lens 117, 117a, from the partial beams, and each signal beam is analyzed by means including at least one linearly polarizing analyser 119, e.g. a Wollaston prism, specific to that beam to generate at least two beams of variable brightness so modulated that the maximum of one coincides with the minimum of the other. These signals are displaced in phase by an angle other than 180 degrees, by a #/4 plate 118, and are evaluated, e.g. by photo-diodes 120 ... 123 to determine the required speed &c. Several modifications are described. In one Fig. 2 (not shown), a phase grating (217a) with a line-gap ratio of 1:1 is associated with the lens 117, and bi-refringent plates (219, 219a) comprise the analyzer. In another, a polarization-neutral divider surface (317) divides the recombined beam, Fig. 3 (not shown), a calcite plate (319) acting as analyzer, and in Fig. 4 and 5 (not shown) the method is applied to a Mach-Zehnder interferometer. In Fig. 4 (not shown), visual comparison of the signal beams is made through eye-pieces (433, 434), and in Fig. 5 (not shown) two recombined beams are produced at (513a) and each is divided at gratings (517, 517a) from which six signal beams are derived. In Fig. 6 (not shown), movement of a linear or radial phase grating (613) is transformed into the required signals, and in Fig. 7 (not shown) the sequence of steps is altered, the recombining of the partial beams occurring at lenses (726 ... 729) after the analyzing step (719, 719a) and just before evaluation (720 ... 723). In Fig. 8 (not shown), a Wollaston prism (813) is the moveable element, a Pockels cell (834) providing the phase displacement between the components of the recombined beam. Fig. 9 (not shown) illustrates the invention applied to a Sagnac type interferometer, and in Fig. 10, shown, a chess board cross grating 1013 is the moveable element and provides four partial bundles, the polarization state of two being changed by bi-refringent near surface mirrors 1050, 1050a. The bundles are recombined and formed into signal beams at neutral divider cubes 1017a, 1017b, for analysis &c. at 1019 ... 1019c, &c. In Fig. 11 (not shown), the moveable element is a Wollaston prism (1113).
