Patent GB-1203896-A (GB)
Title: Improvements in installations for handling bulk materials
Inventor: VIDAL LUCIEN RENE
IPC: E02F3/46
Filed: 1969-05-20
Abstract: 1,203,896. Drag line scrapers for piling loose material. L. R. VIDAL. 20 May, 1969 [22 May, 1968; 31 Dec., 1968], No. 25699/69. Heading B8E.  A drag line scraper for moving loose material comprises a bucket 28, Fig. 1, suspended from a carriage 19, which is moved along a beam 18, pivoted on a tower 1 about a vertical axis, by a cable 13 and a winch 12, is returned by a cable 17 and a winch 16 and has a cable 15 attached between the leading edge of the bucket and a winch 14. In operation, the winches 12, 14 rotate together and as cables 13, 15 are wound in the carriage 19 and the bucket 28 move to the right in Fig. 1. The bucket moves horizontally because the cable 17 is paid out by the winch 16. When the carriage passes under a fixed stop 23 a movable stop 31 on the cable 17 is arrested so that cable 17 is not paid out any further. Since cables 13, 15 are still being wound in by winches 12, 14 the bucket 28 rises diagonally until the sequence of operations is halted by a limit switch. Reversal of the drive causes the cable 17 to return the carriage to the left, cables 13, 15 being simultaneously paid out. When the stop 31 abuts a stop 24 the clutch slips so that cable 17 is halted. Continued rotation of the winches 12, 14 pays out cables 13, 15 so that the carriage moves to the left-hand end of the beam under the weight of the bucket. A band clutch is described with reference to Fig. 3 (not shown). This ensures that the winch 16 is clutched to the winches 12, 14 when the bucket is moving away from the tower but not when it is being wound in. Raising or lowering of the bucket may be controlled by an electromagnetically operated pivoted pawl which co-operates with stops on the winch 16 to prevent its rotation in either direction as desired. In a second embodiment, Fig. 4, a beam 153 is rotated by a pinion 107 and a chain the ends of which are attached to the tower. The operation is substantially as previously described except that the carriage return winch 129, Fig. 6, is clutched to the winches 119, 120 by a pawl 124 and a toothed wheel 123. Slipping is provided for by a plate 126 and friction pads 127.

Abstract: 1,219,267. Light modulators. MULLARD Ltd. 21 May, 1968 [5 June, 1967], No. 25853/67. Heading H4F. [Also in Division H1]  A light modulation system comprises a Faraday effect element in the form of a single crystal of YIG in which at least some of the yttrium or iron is substituted by another element to improve the Figure or Merit (ratio of the Faraday rotation per cm. at saturation to the Saturation magnetization) as compared to YIG itself. For optimum operation the crystal should have a low saturation magnetization, a high specific Faraday rotation, and for broad band operation the effect should be linear over a high proportion of the band of transparency (e.g. between 1À2 and 4À5 microns). The crystal may comprise Y 3 Fe 5-x Ga x-y Al y O 12  wherein x lies between 0À9 and 1À5, preferably 1À2, and 0 # y# x. 0À005 to 0À02 atoms of silicon may also be substituted for some of the Ga and/or Al in the above formula. Indium (In) or Scandium (Sc) may be substituted for some of the iron in YIG at x values from 0À6 to 0À8 for broad-band operation. Europium (Eu) or terbium (Tb) may be substituted for all of the yttrium in YIG. With all the yttrium replaced by Tb or Eu, and also some of the iron replaced by gallium and/or aluminium, good materials as regards both Figure or Merit and shorter wavelength transparency are obtained. In particular, Eu 3 Fe 5 _ X Ga x O 12  where x lies between 0À2 and 0.8, or Tb 3 Fe 5-x Ga x O 12 , where x lies between 0À05 and 0À5, are good Faraday rotators (Aluminium may be interchanged in part or in full for the Gallium). Specific crystals referred to are Y 3 Fe 3 . 85 Ga 1 . 15 O 12  (disc-shaped crystal), and Y 8 Sc 0 . 7 Fe 4 . 3 0 12 .

Title: Improvements in or relating to multi-coloured sheets or coatings of polyvinyl resins
IPC: B32B27/00
Filed: 1948-10-05
Abstract: A process for the manufacture of self-supporting sheets of polyvinyl resins bearing a multi-coloured design comprises printing on a support a design in colours each formed of a suspension of a polyvinyl resin and a pigment in one or more plasticizers, the differently coloured elements of the design extending through to the support surface and covering its whole area, and thereafter causing the printed material to gelatinize by the application of heat.  The resin may be polyvinyl chloride or copolymers of polyvinyl chloride with other polymerisable substances.  The plasticizer may be tricresyl phosphate; lead carbonate may be added as a stabilizer. The design may be printed upon an endless metal belt from which it is removed after gelatinizing.  The resin suspension may be diluted with a volatile solvent in which the plasticizer is soluble but the resin is not. The suspension, after kneading, is stood at a temperature between 25 DEG  and 40 DEG  C. in order that the resin will be swollen by the plasticizer as a pre-stage of gelatinization. Alternatively toluene, xylene or petroleum fractions such as white spirit may be added to achieve this result.  The gelatinization may be effected in a chamber heated by steam or electricity, by means of infra-red rays or high-frequency installations.  A glossy surface may be obtained on the design by subjecting it to radiant heat after gelatinization.

Ice-making, plate apparatus for.-In apparatus comprising upright freezing plates or slabs A and transverse upright and bottom walls A<1>, A<2>, A<3> assembled in a tank so as to provide a set of independent cells for water to be frozen, the edges of the slabs are formed with hollow boxes or chambers C into which the slab pipes B open, the boxes having ports C', C<2> D1, D<2>, communicating with similar ports in adjacent slabs or inthe transverse walls, whereby the number of joints outside the slab is materially reduced. Preferably the transverse walls are cast integrally with the slab, the pipes B being embedded in the casting. The ports in the boxes are formed by the core holes of the casting. The boxes have partitions C<3> staggered at opposite ends so that the medium is circulated in a tortuous passage through the pipes and boxes. The pipes B are straight open-ended pipes, but a second system of pipes G for a refrigerating medium may be embedded in the slab. They are preferably formed of weldless tubes bent into a U- shape, the bends extending outside one edge of the casting, and the free ends at the other edge are connected by welding bends thereto. The slabs are cast with lugs A', A<8> whereby they may be connected by bolts A<9>, and the bottom transverse wall A<3> may have connections K through which air may be supplied for agitating purposes. In the case of slabs at the ends of the tank, only one port C<1>, Fig. 5, is provided in the box C, and the pipes B are suitably bent to open into the box. The bends of the pipe G may at one end be located within the box, or within the equivalent passage at the edge of the slab where the transverse walls are separate, as shown in Fig. 7. A T-fitting B<6>, Fig. 8, may be used to obviate the special form of core hole necessary in the arrangement shown in Fig. 4. The connections E, F for the medium, normally the thawing medium, circulating through the pipes B and boxes are cast with the slabs. Separate intermediate transverse walls H<1> for subdividing the water cells have cast-in bent pipes H<2> extending through the bottom to provide securing means for the walls. One end of each pipe is plugged, and a hole H<6>, Fig. 2, is provided in it for the admission of liquid from the bottom chamber D, the liquid being discharged outside the tank through the other open end of the pipe. Where the second system of pipes G is not used, refrigerant is circulated through the pipes B, and connected passages. According to the Provisional Specification separate transverse walls may be connected to the slabs by bolts extending over the width of the transverse walls, or transverse walls of channel section may be used and be connected by bolts through the flanges of the channels. The bottom wall may contain straight pipes communicating with passages in the upright transverse walls.

Abstract: 151,839. Barton, B. C., and Carr, R. H. Oct. 28, 1919. Presses, governing and controlling; presses, producing part of stroke of, hydraulically; working valves.-In presses in which the ram is moved up to its work by low-pressure liquid and caused tc complete its stroke by high pressure liquid, low-pressure liquid from an inlet t lifts a valve w when permitted by a spindle v<1> and passes through passages 11, 6, 55, 24 and 56 to a port 54 leading to the press cylinder. When the ram reaches its work, the pressure in the cylinder increases and causes a valve 1 to close the passage 6, a smaller quantity of low-pressure liquid thereafter passing through passages 10, 9 in the valve 1. When the pressure in the cylinder is equal to that in the low-pressure pipe, a ram 34 exposed at one end to the first pressure and at the other to the low-pressure supply pressure through a pipe u is in equilibrium, and a ball valve 14 is allowed to open to admit high-pressure liquid from an inlet 16, this liquid passing-through a strainer and an apertured diaphragm. The high-pressure liquid closes the valve w and thus shuts off the lowpressure supply. When the pressing operation is completed, the spindle v<1 >is operated to retain the valve w in closed position, and an exhaust valve 40 is opened, thereby relieving the pressure on the upper end of the ram 34, and allowing the constant pressure on the lower end of the ram to close the high pressure inlet valve 14. The valves and passages may be arranged in a single block, as shown, or distributed between two blocks.
