Patent GB-1256367-A (GB)
Title: Continuous-casting moulds
Inventor: CROWELL RICHARD SHELMIRE
IPC: B22D11/041
Filed: 1968-12-16
Abstract: 1,256,367. Continuous casting. UNITED STATES STEEL CORP. 16 Dec., 1968 [22 Dec., 1967], No. 59785/68. Heading B3F. A refractory collar 11 on the top end of an open-ended mould 10 has a flange 12 depending into the mould cavity 13; gas (such as nitrogen) from passages 22 prevents molten metal entering a space 20 between the flange 12 and the mould wall. Preheating of the flange 12 by an embedded graphite electrical conductor 18 inhibits freezing of the melt within the collar so that scum collecting on the melt surface may be drained off periodically through a spout 17 at one end of the collar 11. Oil is introduced to the mould through passages 24. Melt entering the space 20 is detected by thermocouples 23 which cause the gas pressure to be raised to force it out. The refractory collar 11 has an angle-iron frame 14 with slotted lugs 16 which co-operate with bolts 15 pivoted to the mould top to secure or release the collar.

Several suitable forms of alumina are specified, e.g. alpha, beta, gamma, delta, eta, theta, kappa, chi, rho or amorphous forms, hydrated aluminas being preferred to non-hydrated forms. Preferably the alumina is activated by calcining or by heating in steam to raise the surface area to above 59 m<SP>2</SP>/g. Small amounts of chromium may also be included in the composition.

Patent GB-684655-A (GB)
Abstract: 684,655. Ordnance mountings. AKTIEBOLAGET BOFORS. April 26, 1951 [April 28, 1950], No. 9779/51. Class 92(i) [Also in Group XXX] For sensing when two objects, such as guns or cranes, are in danger of colliding, each is connected to means, such as contacts 13, 15 and associated resistances 12, 14 which provide a voltage proportional to the angles a, #, made by the objects to a line in a given plane, or by the projections of the objects on to a given plane. The contacts are connected as shown to the parts 21, 24, in a circuit comprising a direct current source 20, resistances 18, 19 and rectifiers 22, 23 and the winding 25 of a polarized relay is arranged between the contact 15 and the point 24. The arrangement is such that no current will flow through the winding 25 until the contacts 13, 15 are in such positions as to produce a voltage difference sufficient to exceed that across resistances 18 or 19: it is proved by the aid of Figs. 1 and 2 (not shown) that the angles α and # made by the guns and cranes under such conditions are likely to result in a collision. The contacts 27 of relay 25 lead to terminals 28, 29 of a circuit which may be used for so moving the guns or cranes that they strive to become parallel. An indication giving the position of the guns or cranes in relation to each other is obtained by a second relay 30 and associated circuit 31 to 34. In a modification the potentiometers 12, 14 are replaced by variable transformers in an A.C. circuit, and in another modification the resistances 18, 19 and rectifiers 22, 23 are replaced by polarized relays.

Title: Electric motor driving-gear
IPC: B23Q15/26
Filed: 1978-12-28
Abstract: An electric motor control apparatus has means for stopping the motor M when an output shaft 136 driven thereby is in predetermined angular positions. The said means includes a motor supply circuit containing, in addition to a main control switch CSW, light-emitting diodes LED1, LED2 and corresponding photo-transistors PT1 and PT2. In the said predetermined positions of the output shaft, openings (186, 188) or notches (190, 192) in a rotary member (160) fixed for rotation with the output shaft allow light from one or other of the light-emitting diodes to reach and activate the corresponding photo-transistor, thereby interrupting the circuit and stopping the motor with the output shaft in the respective angular position. Alternatively, permanent magnets mounted on the rotary member may co-operate with a Hall effect element to stop the motor in predetermined angular positions of the output shaft. <IMAGE>

Title: Spectrophotometer Device
IPC: G01N21/90
Filed: 1979-01-11
Abstract: A dual wavelength spectrophotometer for ampoule content inspection, in particular for a ampoule leak detection using the so- called dye bath immersion technique. Light transmitted through the ampoule 3 is received by a bifurcated fiber optic cable 4 providing via a random mix arrangement substantially identical ampoule optical signature signals. Each is directed through preselected interference filters 5, 6, chosen on the one hand on the basis of the dye being used and the glass ampoule and its contents on the other hand. Associated with the filters are respective photodetectors 9, 10, the output signals of which are connected to a difference amplifier 11. The output of the latter is compared in comparator 13 with a preestablished threshold signal, which represents the minimum level of dye from which to effect a reject status. The ampoule contents or a particular component thereof may also be investigated in this manner. The photodetector outputs are also summed in summing amplifier 12 and the resultant compared in another comparator with a second preestablished threshold in order to provide a fail-safe system capability against optical failure and the like. The difference signal/comparison circuit leg may be constructed to provide logarithmic function capability and thus produce an output which is proportional to concentration. Therefrom the concentration of the ampoule contents or the dye can be determined, for example to lie within a preestablished "window". <IMAGE>

Title: Methods of Producing Thin Films
IPC: H01L31/18
Filed: 1979-05-31
Abstract: A thin film of a metallic chalcogenide (a sulphide, selenide or telluride) is produced on a substrate by utilising an organometallic compound as the starting material, which compound includes in its constituents the metal and the chalcogen which would form the desired metallic chalcogenide. The compound is heated and decomposes and the constituents react to produce the metallic chalcogenide on the surface of a substrate. Suitable organic compounds are metallic diethyl dithiocarbamates, enabling a thin film of the sulphide of the corresponding metal to be formed. The metals may be zinc, cadmium, copper or other metals or mixtures thereof. The process enables electroluminescent, photoconductive and photovoltaic layers to be produced by the inclusion of suitable activators or dopants. The substrate may be positioned at a distance from the heated compound so that the vapours given off are deposited on the surface of the substrate.

Title: Heating divers suits etc by exothermic reactions
IPC: B63C11/28
Filed: 1979-08-17
Abstract: The heating of submersible hulls 4, diving suits 5 and other underwater equipment usually involves use of electrical batteries. However, in cold water operations these electrical batteries prove quite inadequate for the task. The invention provides for a self-contained heating system involving the bringing together in a submerged reaction vessel 7 of substances capable of reacting together exothermically. Preferably one of the substances is a metal e.g. aluminium in ingot form 14, and the other substance is an aqueous solution of sodium hydroxide stored in an accumulator bladder 17. The accumulator jacket 18 and the reaction vessel 7 are disposed outside the hull 4. In operation, ambient sea water continually flows through pipe 23 under the action of pump 24, before passing to a helical heat exchanger 21. The heat generated by the exothermic reaction heats the sea- water which passes via a stand-pipe 26 to the inlet end of the diver's hose 6 and to a radiator 10 within the submersible. <IMAGE>

Abstract: A circuit arrangement ME is provided for restoring overload channels in the receiving section of an earth digital voice interpolation- type interface module. A binary configuration indicating a given signal sample, which includes a bit for an overload channel, is transferred to a respective line in a random access memory RAM1-RAM6 during the first half of the channel time. A bit for an overload channel is stored in the second half of the channel time. When the next following binary configuration is received, the overload channel bit is shifted to the left by one position and a second bit is stored in the position previously occupied by it. Upon receiving further binary configurations, the previously stored bits are further shifted to the left until reception of the bits relating to the overload channel has finished. <IMAGE>
