Title: Improvements in and relating to a Method of Measurement of Electric Charges
Inventor: JEAN-CLUCHET
IPC: G01R5/28
Filed: 1968-11-04
Abstract: 1,188,470. Measuring electric charge. COMMISSARIAT A L'ENERGIE ATOMIQUE. Nov. 4, 1968 [Nov. 17, 1967], No. 52223/68. Headings G1Q and G1U. The charge on a capacitor C c  is determined with the aid of an electro-meter of capacitance C e  from three voltage measurements, for each of which a variable D. C. supply (across AD, Fig. 1, not shown) is adjusted to bring the moving element of the electro-meter into a constant reference position. The three measurements are made: (1) with the capacitor and electrometer in series across the supply, the capacitor initially carrying the charge to be measured; (2) as (1) but with the capacitor initially discharged; (3) with the electro-meter alone across the supply. The supply voltage required to attain the reference position is measured in each case, enabling the unknown charge to be deduced without calibrating the electro-meter and without knowing the value of C c  or of any stray capacitance c in parallel with it. Fig. 2 shows a practical arrangement for measuring the charge on an ionization chamber to determine the radiation dose absorbed by it. The ionization chamber itself (not shown) comprises a cylindrical outer electrode and a central electrode, and is fitted into a brass sleeve 6 on the earthed casing 1 of the apparatus. A pin 13, spring-urged towards the chamber, connects the central electrode to the quartz fibre 8 of the electro-meter. The outer shell 9 of the electro-meter is insulated from the casing 1 and connectible via push-button switch 23 to the variable voltage supply. Plunger 35 enables pin 13 to be earthed to discharge the electrometer and the ionization chamber. The quartz fibre is illuminated by a lamp 38 (gas tube) and viewed through a microscope 39. For safety an earthed flexible contact 40 is arranged to engage the pin when the ionization chamber is not in place.

Title: Improvements in or relating to symmetrical current controlling devices
IPC: H03K17/70
Filed: 1963-09-20
Abstract: 1,070,412. Semi-conductor switches. ENERGY CONVERSION DEVICES INCORPORATED. Sept. 20, 1963 [Sept. 28, 1962; Jan. 18, 1963 (3); June 17, 1963], No. 54994/66. Divided out of 1,070,411. Heading H1K. [Also in Divisions G1, H2 and H3] A symmetrical switch comprises a semi-conductor material between ohmic electrodes, the material being reversibly switchable from a blocking to a conductive state. It may be switched from the blocking to the conducting state by application of a direct or alternating voltage the instantaneous value of which exceeds a threshold value and reverts to the blocking state when the instantaneous current falls below a minimum holding value, and thus in every half cycle where an alternating voltage is applied. Superimposition of a direct voltage on the alternating voltage causes an increase in resistance in the conductive state which remains after the removal of the direct voltage, but increasing the applied alternating voltage well above the threshold value decreases the resistance. In a typical device the semi-conductor material is in the form of a body with electrodes on opposed faces or on the same face. Alternatively it is a layer on one face of a conductive or insulating block. Where the block is conductive it may constitute one electrode of a device or the common electrode of a pair of series-connected devices. In each case further control electrodes may be provided on the body or layer. In a particular form of device the body is necked and insulated control electrodes are provided on the necked region between the main electrodes. The semi-conductor material may alternatively be a coating on one or both of two wires which may lie in contact side by side or crossing one another or twisted together Specified mixtures of tellurium with arsenic, germanium, gallium arsenide, silicon, indium antimonide gallium, germanium and silicon, germanium and gallium arsenide, gallium and arsenic, or arsenic and germanium, mixtures of arsenic, tellurium, germanium and silicon, and mixtures of tellurium, arsenic gallium and lead sulphide are suitable materials. Various treatments and methods of providing electrodes to such materials are discussed. The materials may be prepared by grinding up the components, melting in a sealed vessel and grinding or casting the resulting material to the required form. Alternatively they may be vapour deposited on a substrate. For instance, a sequence of layers of Te, As, Ge, As, and Te may be deposited on a steel substrate, the layers unified by heating and tungsten electrodes then provided. It is stated that the materials in general may be improved and stabilized by additions of arsenic, sulphur, phosphorus, antimony, arsenides, sulphides, phosphides and antimonides, gold, carbon, chlorine, oxygen, nickel, iron, manganese, aluminium, caesium and other alkali or alkaline earth metals, by electroforming, and by various mechanical and heat treatments, etching, and radiation bombardment. The theory of operation of the devices is discussed in the Specification.

A machine for crimping a pick 16, Fig. 4, to the stem of a flower (not shown) comprises a base 12 having guide ways 38 on which the picks are placed, e.g. from a stack 14, a pair of push rods 24 slidable in the ways 38 to feed a pick between crimping jaws 48 which are movable at right angles to the direction of movement of the rods 24, and a cam 64 operated by fluid pressure for closing the jaws 48. Artificial flower stems of wire or polyethylene are referred to, the picks being of thin metal and having arms 22 which are closed about a stem by corresponding elements of the jaws 48. These are cammed about pivots by a bell-crank lever 62 operated, against a return spring, by a pneumatic cylinder 112 which is supplied by a valve 100 controlled by a lever 116. A further pneumatic cylinder 120, for operating the feed rods 24, is supplied through a sensing valve 130, the piston 130a of which is retracted by a pick positioned for crimping, thus interrupting the supply to cylinder 120. The supply is resumed to advance a further pick when a crimped pick is removed. The valve 130 may be operated by a lever 136, Fig. 2 (not shown). Picks are fed beneath a spring 74, and a resilient member B cushions return movements of a feed-slide 42 which are effected by a spring. In another construction, Fig. 7, the feed slide is operated by a hand-lever 150 which also controls a valve 164 for operating the crimping cylinder 112. A further construction, in which both crimping and feeding are operated pneumatically, has a switch (200), Fig. 8 (not shown), operated by placing a flower stem in the machine, the switch controls a solenoid for operating the valve. Alternatively, the stem may operate the valve direct.
