Abstract: 874,608. Lowering apparatus. BILLING- TON, J. H. Dec. 8, 1959 [Sept. 17, 1958], No. 29728/58. Class 78 (1). Crates are lowered from position 10 to position 11 by falling in cascade fashion along shoots 12, 13. The shoots 13 form a set pivoted at 14 on pillar 15 and extend rightwards as far as a roller 18. The shoots 12 form a set pivoted at 14 on pillar 16 and extend leftwards as far as a roller 18. Each shoot is balanced such that normally the inner end projects upwards to receive a crate and such that when the crate is on the platform, the shoot projects downwards to discharge the crate. The crate, in falling, thus descends in a zig-zag path, the gap between each set of shoots 12 and 13 being bridged by the rollers 18 carried by pillars 17 and the movement of each set of shoots being in unison and being braked by virtue of each shoot being connected to ropes 20 connected to dashpots 19.

Title: Improvements in bombardment induced conductivity devices
IPC: G01T1/26
Filed: 1948-11-16
Abstract: 676,425. Discharge apparatus; manipulating particles. WESTERN ELECTRIC CO., Inc. Nov. 16, 1948 [Dec. 4, 1947], No. 29783/48. Addition to 676,411. Classes 39 (i) and 39 (iv). [Also in Group XL (b)] A solid insulating body producing discrete impulses of current under the impact of radiation (including X and y rays as well as α, p particles, electrons and mesons) is subjected to an alternating voltage field or is made so thin and the direct voltage field made so high that a space charge effect is avoided. The insulating body is preferably a single crystal of diamond having electrodes as disclosed in the parent Specification. It is suggested that electrons released from atoms may enter the field of foreign atoms or imperfections in the crystal and form a space charge, so that an alternating voltage of, e.g., 20 cycles/second across the crystal will reverse the movement of electrons and tend to remove the space charge. Similarly a very intense direct voltage field will tend to overcome the field of the imperfections. As shown in Fig. 9, a hot cathode emits electrons which are modulated by a grid 49 and pass to an anode 47 constituted by a crystal whose conductivity changes in accordance with the electrons striking it; an alternating field is provided by source 52 and a source 54 acts somewhat as the normal anode voltage source; the amplified output is taken from 50. In Fig. 6, the cathode rays from 21 are modulated in intensity by source of signals 28 to impinge on the crystal 20 and provide an amplified output; the cathode-rays may be modulated in deflection to hit or miss the crystal, which thus acts as a pulse generator, Fig. 7 (not shown).

Title: Improvements in or relating to electric discharge tubes
IPC: H01J9/04
Filed: 1926-11-25
Abstract: 282,205. M-O Valve Co., Ltd., Bartlett, A. C., and Ryde, J. W. Nov. 25. 1926. Vacuum tubes.-A cathode for a gas discharge tube, such as a biphase rectifier, consists of a metal containing nickel or iron coated with a compound of an alkaline earth metal such as barium nitrate, and subjected to heat treatment whereby a compound of alkaline earth metal and the metal of the electrode is formed which enables the running potential to be lower than that of the uncoated electrode. In the preferred process a nickel electrode is coated with moistened barium nitrate and dried. The coated electrode is heated in a vacuum furnace or in air to 750 C. for half-an-hour and then cooled. During the heating stage the nitrate reacts with nickel and changes to a reddish-brown colour. A coating which is black and crystalline, or leadgrey or white is unsuitable. The electrode may be exposed to air without adverse effect. A biphase rectifier has a single cathode and two anodes.

Abstract: 784,144. Photo-electric apparatus for examining objects. CASELLA (ELECTRONICS), Ltd. Oct. 21, 1955 [Oct. 21, 1954], No. 30302/54. Class 40 (3). Apparatus for examining objects such as microscope slides and photographic plates or films comprises a mask 1, having an aperture such as a slit 2 illuminated by means of a steady light source 3, means for scanning the image of the aperture over the object 11 and registering or recording means 19 indicating the light transmitted by the object as determined by photocell 18. The scanning means comprises a rectangular (or other multisided) prism 5 rotated so as to cause the image of the slit to move across a section of the object. The repeated vertical scans across the object caused by rotation of the prism 5 may be combined with movement of the object at rightangles to the direction of scan so that the whole area of the object is investigated. As shown, a sharp reduced image of the mask aperture is obtained by introducing an inverse microscope 8 between the prism 5 and the image plane. This also reduces the linear scanning movement due to rotation of the prism and to prevent the reduction the inverse microscope may be placed before the prism (Fig. 5, not shown). Alternatively the image produced by the inverse microscope may be formed in the plane of a second apertured mask and an optical magnifying system used to produce an image in the plane of the object (Fig. 3, not shown). In a modification of the apparatus two dimensional scanning of a fixed object is achieved by the use of two refractive prisms 5a and 5b rotating about axes at right-angles to each other. The apparatus may be used for particle counting, size determination, and density or colour measurement. Specification 714,350 is referred to.
