Abstract: 1,002,556. Ball mills; polymerizing apparatus. A. SZEGVARI. Oct. 27, 1961 [Oct. 28, 1960], No. 38637/61. Headings B1X and B2A. In a continuous process for the coarse or fine grinding of material while suspended in a liquid, the grinding elements are agitated so that repeated contact occurs between them to cause the progressive grinding of the material as it advances through the grinding zone. In the apparatus for grinding material, the suspension is continuously fed by a pump 3 into either the top or the bottom as shown of a cylindrical vessel 1, which may be jacketed for temperature control, and the suspension of the ground product continuously removed through a screen 7 from the opposite end at 4 of the vessel after being acted upon within the vessel by the grinding elements 8 which are agitated by a rotatable shaft 5 having arms 6 which extend to within a clearance of three grinding element diameters of the inner wall of the vessel and arranged at an angle to one another along the length of the shaft. Agitation of the suspension produces a general helical flow without lateral flow. Alternatively, the vessel may be arranged to rotate to effect agitation and the screen 7 for retaining the grinding elements within the vessel arranged vertically so that the final suspension flows over the top edge of the vessel. Further, the grinding elements may be removed from the vessel with the suspension and subsequently separated from it. The apparatus described is based on Specification 716,361 which is primarily for "batch processing". It is stated that the invention may be applied to polymerization.

Title: Navigational system
IPC: G01C21/00
Filed: 1967-08-25
Abstract: 1523713 Automatic control COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT 25 Aug 1967 [26 Aug 1966] 39311/67 Heading G3N In an aircraft flight control system an inertial guidance system is provided with continuous correction. The actual craft position is compared with a desired position and the error difference  signal is applied to the craft flight controller 13 in addition to the inertial control signals from 10. A film carried in the craft stores the profile information of a strip of terrain over which the craft is routed. The film is optically scanned in a comparison device 20 which is fed with the actual craft altitude measurements, from an echo altimeter 28 so as to derive the instantaneous craft path. This information is supplied to an evaluator 25 which also receives information from a calculator 21 corresponding to the required craft zone position and which derives the course deviation parameters used to effect correction. In the comparison device, 20, the film, 100, contains the profile information of the terrain over which the craft is guided by the inertial control, 10. The items 32, L and RS scan the film, 100, moved in correspondence with aircraft speed, and form images of contour lines of the terrain above which the craft is flying. A large number of contour lines are formed to provide a sharp definition of the craft position point. The latter is projected by the lens, L, on to the receiving surface, RS, of a vidicon tube, the scanning beam of which picks out the point of greatest electric charge, i.e. the craft present position, and evaluates the track deviation as represented by the distance of the craft position point from the centre point of RS. The mark, 31, is rotated in correspondence with the measured craft altitude so that at each altitude the marks q and p are aligned and a clear image is formed at FRS and a contour line is traced as the film 100 is moved. In an alternative form the diffused light source, 30, is replaced by a laser which produces sets of diffraction patterns corresponding to different craft altitudes which are focussed to produce the contour line images.

Filed: 1972-08-25
Abstract: 1419514 Shaft encoders WHESSOE Ltd 24 Aug 1973 [25 Aug 1972] 39705/72 Heading G1A An incremental shaft encoder comprises a disc mounted for rotation with the shaft and having a plurality of IR opaque elements which co-operate with'five pairs of IR sources and detectors spaced an even number of fifths of the widths of the opaque elements and connected to decoding logic which develops ten distinct signals representative of the direction and amount of the shaft rotation, and a counter being arranged to develop a count representative of the shaft position. The encoder comprises a toothed disc 1 with five IR sources 4 and five detectors 5 arranged with a spacing of 4/5 of the width of a tooth 3. The outputs of the detectors form a 2-or-3-out-of-5 code which is decoded by a logic circuit to produce an (inverse) 1-out-of-10 code. An encoding logic circuit converts this to a BCD code for application to the least significant digit (units) of an output display. A pair of bi-stable triggers also respond to combinations of the decoded signals to determine the direction of rotation of the disc and to control two monostables to apply pulses to the forward and reverse inputs of a "tens" counter which is followed by "hundreds" and "thousands" counters. Further logic circuitry is connected to the detector outputs to indentify false codes and set a fault bi-stable which operates an indicator. Insertion of a tool to bridge a pair of contacts and depression of a "lamp-test" button which applies a testing signal to the decoders driving the display, clears the fault bi-stable and resets the counters to states determined by plug connectors and chosen for convenience in realigning the system. The sources may be IR LEDs and the detectors phototransistors. The vanes may extend axially instead of radially. The spacing between the detectors may be made equal to 2/5 of the vane width so that all five co-operate with a single vane. Position outputs for control or recording purposes may be provided. The system may be linked to a float for liquid level measurement, Fig.4 (not shown).

Title: Improvements in and relating to methods and apparatus for developing electrophotographic materials
IPC: G03D5/06
Filed: 1960-11-22
Abstract: An apparatus for coating liquids on web comprises a bath containing the liquid, a roller mounted to rotate with its lower portion immerse in the liquid, a feed mechanism for traversing the web across the upper portion of the roller, means for holding the web under yielding pressure against the roller, a main motor which is normally effective to operate the feed mechanism and to rotate the roller so that its upper portion travels in the same direction as the web and that the peripheral speed is sufficiently in excess of the linear speed of the web to form and maintain a turbulent head of liquid and a normally ineffective idler motor, operative on stoppage of the main motor, to drive the roller at a slower speed.  The web may be held under yielding pressure either by spring-loaded guide rollers or by an air blast and the web is in contact with the roller over an arc of 7 degrees or less.  If the feed mechanism, normal a roller driven through a slipping clutch to avoid excess tension, is stopped the roller in the liquid is switched to a lower speed by the use of the idler motor, coupled to the roller by a freewheel connection, which prevents accumulation of liquid on the web.

Filed: 1974-09-13
Abstract: 1435250 Wire saws LUMALAMPAN AB 13 Sept 1974 40076/74 Heading B3D [Also in Division D1] In a method of making a wire saw crystals of hard material are deposited on a support wire by heat in a gaseous atmosphere which includes at least one substance which can yield the desired crystals of hard material. The support wire may be formed from tungsten, molybdenum, tantalum, osmium and rhenium or alloys of these and the substances providing the hard material which form the layers of crystals on the support wire are provided from borides, nitrides and carbides. In the process of making the saw the wire is heated by passing an electric current through it whilst it is located in a reaction chamber containing a gaseous atmosphere which incorporates the substance providing the hard material, the latter being deposited by thermal decomposition or reduction to form hard crystals on the wire surface well suited to the sawing function. The crystal formation is dependent on the control of the temperature, the nature of the constituents of the gaseous material, the pressure of the gaseous material and the nature of the support wire which controls the rate of diffusion of the crystals formed thereon. The coating of the wire may be carried out in two stages by providing two successive layers of crystals, the first layer inhibiting the crystal growth of the second layer.
