Inventor: COOPER VICTOR JAMES
IPC: B21B38/00
Filed: 1962-08-28
Abstract: 982,664. Optical testing apparatus. MARCONI CO. Ltd. July 19,1963 [Aug. 28,1962], No. 32980/62. Heading G2J. To determine faults in a reflecting surface a standard mark is reflected by that surface and its image compared with an identical reference mark, irregularities in the surface producing "kinks" in the image of the mark. The standard mark R is formed by reflecting light from the source 6 on to the surface 1 by the mirror 3, the reference mark S being the shadow cast by that mirror 3 and the light source 4. The surface may be scanned by a T.V. camera, the results being monitored or displayed on a C.R.O. When the surface 1 is moving, the mirror drum 2 is rotated at substantially the same speed to obtain a stroboscopic effect each mirror 3 may comprise a number of reflecting strips to give a "grating" effect.

Title: Improvements relating to electricity maximum demand indicators
IPC: G01R11/56
Filed: 1933-11-27
Abstract: 426,362. Supply meters. CHAMBERLAIN & HOOKHAM, Ltd., and JAMES, S., 4, New Bartholomew Street, Birmingham. Nov. 27, 1933, No. 33116. [Class 37] In order to give an alarm or reduce the load when a maximum demand indicator is approaching a predetermined position, an epicyclic mechanism is adapted to be driven by a meter and a constant-speed motor, the joint effect being to operate a circuit controlling mechanism for actuating a signal or opening the circuit of power-consuming apparatus. A pair of sun pinions a, b are connected by a planet pinion c carried by an arm on an arbor h, on which the sun pinions are freely mounted. The sun pinion a is driven by the meter through gearing d, e, the other sun pinion b being driven through gearing f, g by an electric or other constant speed motor. The speed of the sun pinion b is arranged to correspond with the speed of the sun pinion a when the load is slightly less than the predetermined maximum. In alignment with the arbor h, and connected to it by gearing j, k, is a second arbor i carrying an insulating drum l on which is mounted a metal ring m having an extension n at one side. Spring contacts o, p bear on the ring m and the cylinder l so as to close a circuit when the extension n engages the contact p. At predetermined time intervals the pinions k; j are separated momentarily, allowing a spring q to return the drum l to its initial position determined by the engagement of a projection r on the drum with a resilient or spring-controlled stop s. Instead of separating the wheels k any other parts of the train actuating the drum may be separated, for example, the wheels j or any of the wheels a, b, c. In place of the extension n a stepped segment may be provided so that a number of contacts may be closed successively so that machines may be successively cut out while the demand is rising in the neighbourhood of the maximum. Alternatively, a cam may lift a spring contact into engagement with another contact or contacts.

Patent GB-469877-A (GB)
Title: Improvements relating to the electrostatic separation of particles
IPC: B03C7/00
Filed: 1935-11-29
Abstract: 469,877. Electrostatic separators; treating ores. WIEGAND, E. L. Nov. 29, 1935, No. 33141. Convention date, Dec. 3, 1934. [Classes 72 and 82 (i)] In the electrostatic separation of a mixture of dry material particles, the separation is effected at a temperature which is above 250‹ F. but below the temperature at which the desired separation is prevented through agglomeration of the particles by fusion, the selected temperature being one at which the desired separation is effected by reason of the differentiation in the motion response, brought about by heating, of the particles to the electrostatic field. The separated class of particles so obtained may be resubjected to the same process at a different temperature within the same range to effect a further separation. The selected temperature used is preferably one which approximates to the temperature at which the separated particles are used. The material to be treated is heated in a furnace 36 heated to the selected temperature, preferably by heating elements 36, and flows through a spout 37 into a duct 21 and then on to a cone 26 whence it flows into the electrostatic field produced between an annular electrode 45 connected to the positive terminal of a variable unidirectional electric circuit, the negative terminal of which is connected to the remainder of the apparatus, preferably to the cone 26 and gate 29. The flow of the material from the cone is controlled by the adjustablymounted gate 29, and the latter as well as the duct 21 being provided with heating elements. Due to the difference in motion responses produced in the different kinds of materials in the mixture treated, the separated classes will collect in the containers 46, 47, 48 and pass to receptacles 52. The upper ends of the division walls of the containers are provided with adjustably mounted gates 55, 56. The cone 26 may be vibrated or jogged in any convenient manner.

Title: Cooling device for continuously cast strands
IPC: B05B12/00
Filed: 1974-07-26
Abstract: 1481220 Continuous casting VEREINIGTE OSTERREICHISCHE EISEN-UND STAHLWERKE ALPINE MONTAN AG 26 July 1974 [27 July 1973] 33162/74 Heading B3F A continuously cast slab 2 is cooled by spray from nozzles 10 distributed across the width and over a given length of the strand path and are displaced, during casting, by means which displace them over horizontal straight paths parallel to the strand surface and transversely of the strand within a given displacement range. As shown the nozzles 10 are in rows on consecutive pairs of headers 9, 9, 11, 11 and 12, 12 at the ends of pipes 13, 14 and 15 paired in consecutive cooling sections 6, 7, 8 and which can slide in bearings 16 to move the headers and nozzles between limits 17 and 18 on either side of the strand axis 20. The headers are moved back and forth during casting, by fluid-actuated pistons, electric motor or crank rods, in a cyclically uniform, e.g. sinusoidal way or in an irregular way with a longer dwell period near the strand axis 20 then near the edges 19. The headers 11 are staggered in transverse position with respect to headers 9, 12 as indicated, so that they approach one another as the others move apart, and vice versa. The arrangements are applied at both broad sides of the strand path. When the strand width is changed, the positions of the limits 18 are changed, e.g. by changing a limit switch. The positions of the limits 17 are chosen so that the middle zone is sprayed when the opposed headers of a pair are at their closest.  There may be a single nozzle in each cooling section 6, 7 or 8, moving back and forth between the limits 18, instead of a pair moving towards and away from each other. The cooling sections 6, 7, 8 follow an oscillating mould and are followed by two pairs of withdrawal rollers (4) with intervening guide rollers (3).

Title: Improved process for the conversion of mineral oils into hydrocarbons of low boiling point
IPC: C10G1/00
Filed: 1928-11-15
Abstract: 325,487. Kamm, E. D., Odams, R. C., and Imperial Chemical Industries, Ltd. Nov. 15, 1928. Hydrogenation, destructive; hydrocarbons, cracking.-Motor spirit is obtained from coal paste or crude oil by submitting these materials to destructive hydrogenation, part of the products being cracked while the undesired or unchanged liquid products are returned to the destructive hydrogenation stage. The raw material is supplied by a pipe 13 to a, pump 12 which forces it into a hydrogenation tower 1. The products pass by a pipe 14 to a heavy oil catch-pot 2 maintained at 350‹ C.;.the heavy oil is returned by a pipe 15 to the pump 12. The uncondensed vapours pass to a condenser 3, where the middle oil is condensed and passed to a catch-pot 6 maintained at 200‹ C. Petrol vapour passes on by a pipe 18 to a condenser 4 and to a catch-pot 5 at normal temperature. Middle oil passes from the catch-pot 6 into a cracking still 7 under pressure and returns by a pipe 22 to the heavy oil catch-pot 2. Hydrogen from the petrol catch-pot 5 returns through a washer 24 to the tower 1, make-up hydrogen being added at 26. In an alternative form the cracked middle oil passes to a flashing chamber at 350‹ C., where it is separated into a heavy oil fraction for re-cycling and a middle oil and petrol fraction. The latter fraction is separated in a dephlegmating column, the middle oil being returned to the cracking still and the petrol passing to a condenser. In an example an oil containing 86 per cent boiling above 300‹ C. and 14 per cent boiling between 200-300‹ C. was treated with hydrogen at 200 atmospheres and 450‹ C. for one hour in the presence of 5 per cent of hydrated ferric oxide. The product contained 20 per cent of petrol and 30 per cent of middle oil, the remainder being returned for re-treatment. The middle oil was cracked at 450‹ C. for 15 mins. The product contained 37 per cent of petrol, 45 per cent of middle oil, and a residue which was returned for re-hydrogenation. The hydrogenation is preferably performed at pressures above 100 atmospheres, whereby the formation of gas is diminished; the cracking is performed at a. lower pressure.

Abstract: 1,121,750. Measuring rate of rotation. HONEYWELL Inc. July 21, 1967 [July 25, 1966; Aug.29, 1966], No.33578/67. Heading G1N. Apparatus for measuring rate of rotation comprises an electrically conductive vibratory wire 12 restrained at three points 14, 22, 16 dividing the wire into first and second portions each extending through a respective one of two perpendicular magnetic fields, and a signal generator 42 connected to points 14, 22 for passing an alternating current through the first portion of the wire to cause the wire to vibrate in the vertical plane as seen in the drawing, so that when the apparatus is rotated about the longitudinal axis of the wire 12, the second portion of the wire tends to lag relative to the support 10 and will thus intersect lines of the magnetic field so that an alternating voltage is generated in the second portion of the wire. The generated voltage has an amplitude dependent on the rate of rotation and a phase dependent on the direction of rotation. The frequency of generator 42 is the same as the natural resonant frequency of the wire. Point 22 may be at the midpoint of wire 10 or may be offset therefrom by up to 6% of the total length of the wire to damp out unwanted vibrations. There may be two supports 22 one each side of the midpoint of the wire. As shown, the support 22 is in the form of a cross wire rigidly attached to wire 12. Instead, a knife edge or a small hole in a bracket may be used. The two portions of the wire 12 may be of different weights.
