Cine cartoon films are prepared by the use of superposed displaceably or deformable two-dimensional elements, horizontally mounted and each comprising a part of a complete cartoon figure, these elements being manipulated by an operator and continuously photographed to provide animation of the complete figure. The displaceable inter-connected elements, (17, 18, 19, 20, 21, 22 and 23) as in Figs. 5, 6 (not shown) are pivotally mounted on the transparent plates (13a, 13b, 13c, 13d), which are manipulated through handles (16), and which are placed between spaced fixed masking plates (9) hinged together at (11). A slotted finger (14) on each plate (13) engages a pin on the underlying plate (9). Camera 3 is mounted on rails 6 vertically above the apertures 10 in Plates 9, and lamp 8, which may be tubular, are mounted around the camera lens (3a) as in Fig. 3 (not shown). More than one figure may be used in the apparatus. Unwanted reflections may be avoided the use of polarised light with filters. Ultraviolet light may be used with fluorescent movable elements. In another embodiment, the head (31) of a figure 13 made of deformable sheet material and is manually deformed through rods(33) attached at points (32) of the head, as in Figs.7, 8 (not shown).

Abstract: 1515888 Rolling mill guide jaws HERMANN BERSTORFF MASCHINENBAU GmbH 31 Oct 1975 [28 Nov 1974] 45341/75 Heading B5A A guide jaw for a rolling mill or calender is adjustable so as to accommodate to relative adjustment of the rolls to prevent the lateral emergence of working material. The guide jaw includes a fixed carrier 9 upon which a base plate 11 is slidably mounted by means of a groove and key arrangement 16, 17. Adjustment of the plate relative to the carrier is effected by a screwed rod 34 which bears upon the upper edge of the plate. Guide lugs 18 and 19 are cast atop the base plate and receive a pivot shaft 23 which is rotatable in the lugs but restrained against longitudinal movement relative to them by a pin 25 which engages an annular locking groove in the shaft. One end of the pivot shaft is squared off and carries a lever 27 biased by a spring 29 to a position in which it is locked against rotation by a projection which engages a projection 32 of the carrier 9. An intermediate plate 38 is slidably mounted along the pivot shaft by means of lugs 39, 41, 42 and is adjustable along the shaft by means of nuts 45, 46. A material engaging jaw plate 52 is rotatably mounted on the intermediate plate by means of a flanged disc 56 which engages a centrally located recess 57 of the intermediate plate. The jaw plate is rotated relative to the intermediate plate by means of adjusting screws 49, 51 rotatably mounted in supports 47, 48 welded to the lugs 39, 41. In use, relative adjustment of the rolls is accommodated by suitable adjustment of the base plate over the carrier, the intermediate plate along the base plate, and the jaw plate over the intermediate plate. To move the guide jaw clear of the rolls, the lever 27 is pulled back against the spring 29 to withdraw projection 31 from projection 32 and the lever is then manipulated to rotate the pivot shaft and then pivot the intermediate and jaw plates from the roll gap.

A cartridge 10 carries a number of indicia 18, such as the names of different types of film which it may contain. The leading edge 22 of the film which extends from the gate 16 of the cartridge has a mark such as a notch 24, which aligns with one of the indicia 18. When the cartridge is used to take up a reel of exposed film, the trailing end of the film has a similar notch (34), Fig. 2 (not shown). Thus the type of film in the cartridge is readily identifiable to the photographer or to the film processor.

An apparatus comprises a submerged pump 31 supplying slurry to a nozzle 47, air and liquid being aspirated through partly immersed apertures 52 the lower edges of which constitute the inlet of the aspiration tube 51. By opening the valve, 62 part of the slurry flow may be discharged to a mixing chamber 61 where pressurised dilution liquid is added, the diluted slurry then passing through conduit 27 to a place of use. The waste may be contained in a tank (20, Figs 1 and 2, not shown) divided into two chambers (22, 23) between which the slurry is circulated by the aerator and a return pipe (24); or in an oval channel (80, Fig 5, not shown) round which it is circulated; or a rectangular lagoon (85, Fig 11, not shown) having floating barriers (103, 108) to define flow paths. The aeration apparatus may be supported on floats (87) and have a clearing rod (101, Fig 10, not shown) for the nozzle 47. Preferably the nozzle is spaced more than 15 diameters above the liquid surface; the inlet of the aspiration tube is 5 to 6 nozzle diameters below the surface; the length of the aspirator tube is 30 to 40 times, and its diameter 3 to 4 times, the nozzle diameter; and the stream of liquid strikes the surface at an angle sufficient to ensure penetration but less than 85.

Abstract: <PICT:0961200/C6-C7/1> Chromic acid is made electrolytically, using alkali metal chromate solution as anolyte in a two-compartment cell the permionic barrier of which is permeable to alkali metal ions but impermeable to CrO3 ion, continuing electrolysis until the alkali metal oxide content is less than 11% by weight, and preferably below 5%, then withdrawing the anolyte and isolating CrO3 therefrom. The catholyte may be NaOH, Na2CO3, or NaHCO3 solution.  Preferably the Na2O to CrO3 ratio in the anolyte is maintained at 1:3 to 1:15, and at 60-80  DEG C. The permeonic diaphragm may be asbestos impregnated with a polymer, e.g. maleic anhydride polymerized with divinyl benzene or styrene, and is mounted in contact with the cathode and slightly spaced from the anode consisting of lead coated steel sheet. A range of polymers are described as impregnating compounds.  The anolyte is continuously withdrawn and the CrO3 content concentrated to about 67% solution in an evaporating tower fed at its base with hot air.  The concentrate is then cooled and the CrO3 crystalized out to form a slurry which is then filtered or centrifuged. Specifications 961,198 and 961,199 are referred to.

A railway car has a centre sill 10 extending longitudinally thereof and has at each of its ends a draft rigging including a vertical yoke 24 contained within a horizontal yoke 20, each of the yokes being free to move longitudinally with respect to the other and to the sill, follower blocks 27 and 28 abutting the yokes 20 and 24, respectively, and a cushion 29 interposed between them. Shanks 21 and 25 are integral with yokes 20 and 24, respectively, and shank 25 is slotted at 26. A coupler shank 23, slotted at 30 to receive a key 31, penetrates yoke 20, the key 31 extending into a slot 32 in yoke 20 with which it makes contact in draft when pressure is applied through blocks 27 and 28 upon the cushion 29 and a key 33 extending through slot 26 holds yoke 24 against movement. In draft, the shank 23 is drawn away from yoke 24 and shank 21 away from the cushion 29. In buff, the struck coupler shank applies pressure to yoke 24, key 31 moving in slot 32 in yoke 20 and in slots 35 in the centre sill. The movement displaces yoke 24 causing shank 25 to move and key 33 to move in slot 22. Cushion 29 is compressed and the shanks 21 and 25 penetrate the bolster assembly 16, pressure applied to the cushion tube 19 being transmitted to the non struck end. Key 33 travels in slots 37 and 38 in sill 10 and bolster assembly 16 as tube 19 moves away from the draft stops 34. In buff, at the non-struck end, tube 19 moves shank 21 and yoke 20 to the left, applying pressure to cushion 29. Block 27 is engaged by yoke 20 applying pressure on block 28 which is held against movement since yoke 24 is stopped by key 33 contacting stop 34.

In all cases the volume of space in the recess is not entirely occupied by the ring. The inner edges of the recess are preferably bevelled, and a spring ring may be provided to urge outward the part of the ring in the recess. The cap 10 may carry a seal acting on the reduced section of the cable; this may be of similar pattern to the invention, or otherwise. The frusto-conical outer member gripping the armour may be on a collet sleeve separate from the cap, or omitted if the cable is unarmoured.

The resistive network 24-27 along with feedback resistor 18 of the first solid state operational amplifier 15 ensure that the amplifier output voltage is -I 1 R s . The current from the other wire 4 sets up a voltage I 2  Rs at terminal 11.
