Abstract: 1,251,333. Electron beam irradiation apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 25 Oct., 1968 [31 Oct., 1967], No. 49528/67. Heading H1D. An electron gun for emitting a sheet electron beam through a window on to an object to be irradiated, comprises a tubular anode 9, Fig. 1, provided with the window 12, an electron emitter filament 1 and a slotted intermediate tubular focusing and accelerating electrode 5 in which the slot is fitted with a wire mesh 7 to prevent the field between the electrode 5 and the anode 9 from penetrating into the space between the electrode 5 and the filament 1. The anode 9 is earthed, the electrode 5 held at a negative potential of 25-300 kV. and the filament 1 and a further slotted tubular electrode 3 held at a potential of 200- 2000 V. negative with respect to the electrode 5. The accelerating section within the electrode 5 is operated at a low voltage gradient of e.g. 500 volts per cm. and the second accelerating section between the mesh 7 and the window 12 at a high voltage gradient of e.g. 30 kV. per cm. The wire mesh 7 may have about 20 wires of 0À01 inch diameter per inch and the wires may be inclined at an angle of about 20 degrees to the longitudinal axis of the beam so as to prevent striations in the final beam. The slotted tube 3 may be of magnetic material with a filament feed wire (14, Fig. 2) together with the filament forming a single turn induction loop whereby a transverse magnetic field (15) is produced across the slot in the electrode 3, (3a) deflects low energy electrons longitudinally by an angle sufficient to eliminate shadows from the filament supports 2. The gun of Fig. 1 may be modified to produce angularly spaced multiple beams (Fig. 3). In the modification of Fig. 4 the tube 3 is replaced by focusing electrodes 16 mounted on the filament support plate 17. Each focusing electrode 16 may be constructed from a thin metal plate having a high resistivity or each electrode 16 may be segmented into a longitudinal array of plates (Fig. 5) interconnected by resistors such that when the filament 1 and the electrodes 16 are supplied with A.C. the instantaneous voltage applied to each pair of electrodes matches that applied to the adjacent region of the filament. A potential difference may be maintained between the electrodes 16 and the filament 1. In further modifications the electrodes 16 of Fig. 4 may be replaced by a single resistive planar mesh electrode or by a longitudinal array of mesh electrodes electrically interconnected mesh electrodes, an additional mesh electrode may be incorporated into the gun of Fig. 4. In the gun of Fig. 7 two beams are produced in diametrically opposite directions through the windows 12 in anode 9. A mesh electrode 27 is provided between the emitter filament 1 and each mesh window 7 in the tubular electrode 5. In the multiple beam gun of Fig. 8, radial electrodes 32, 33 split the electron stream emitted by the filament 1 into three separate beams. The electrodes 32, 33 may be constructed from a number of electrically inter-connected plates.

Abstract: 1296714 Endless conveyers GUENTHER SYSTEMS Inc 9 Feb 1970 [11 Feb 1969] 6039/70 Heading B8A An endless conveyer comprises a series of pairs of endless members 335-341 (only one member of each pair visible in Fig. 2) which have a substantially common path along a downward run A and a lower horizontal run B but are progressively relatively offset (in a horizontal direction) along their upwardly rising runs. Load-carrying platforms C are formed by flexible members 344 (Fig. 3) secured to a series of tubular members 346-352. Each member 346-352 is connected laterally between the two endless members of a respective pair of members 335-341. The endless members are chains and are secured to the tubular members as shown in Fig. 4. The platforms C thus form a horizontal load carrying surface from a load-receiving area immediately downstream from sprockets 334 around which all the chains pass to sprockets 328 at the downstream end of the upper horizontal run. As the platform flexes round the sprockets 328, the load is forced by the remaining horizontal trailing portion of the platform on to load delivery platform D feeding an aircraft. Parallel linkage under the action of jacks 26 enables a lower section 262 of the conveyer to be extended upwardly or to be lowered. Further jacks enable vertical adjustment of the load delivery platform D. The invention may be applied to lifting loads over obstacles (Fig. 6, not shown).

Abstract: 1316922 Weighing apparatus BIZERBA Ltd 25 Jan 1971 [27 Jan 1971] 3250/71 Heading G1W A spring balance such as a counter scale adaptable to register in different systems of weight units, e.g. avoirdupois and metric, comprises at least one coil spring 10 having two anchors 16, 17 associated with different numbers of spring coils, one anchor 17 being floating while the balance registers according to one system of weight units, and being held by means 19 while the balance registers according to the other system. In Fig. 1, a fixed anchor 16 and a floating anchor 17 both engage the same spring 10 and are adjustable along the length of the spring. An arm 19 pivoted at 20 is spring-loaded against a stop 18, where it is clear of the anchor 17. When it is brought into a second position and held by a latch 22, V-notches 23 engage the anchor 17 to fix it. In a modification, Fig. 5, the anchor 16 is held stationary when the anchor 17 is floating, by engagement of an arm 35 of the arm 19 with a bell-crank 30 carrying the anchor 16. In this case, the holding force of spring 21 must be greater than the tension of spring 10 under maximum load. When the arm 19 is moved to its second position to hold the anchor 17, the anchor 16 is moved up to relax the spring 10, the pointer 38 initially moving away from zero. As the anchor 17 is engaged, the upper part of spring 10 is tensioned to move the pointer back to zero. In Fig. 3, springs 26, 27 in series are interconnected by the arm 19 which when floating allows both springs to act, and when latched, renders the spring 27 ineffective. The mechanism may be inter-connected by rod 40, Fig. 5, with a scale plate shifting mechanism as described in Specification 1316921.
