Abstract: 1,034,265. Endless conveyers. ASSER ENGINEERING Ltd. Oct. 28, 1964 [Oct. 29, 1963], No. 42618/63. Heading B8A. [Also in Division A2] A machine for the continuous manufacture of confectionery, such as tarts, pies and cakes, comprises a motor-driven endless conveyer, e.g. comprising twin endless chains, and one or more than one processing unit, e.g. a unit for laying pastry, for bases of tarts, in tins carried by pallets on the conveyer, a blocking unit for forming the bases of the tarts, a unit for depositing fillings into the formed bases, a unit for laying pastry, for lids, over the filled bases, and a blocking unit for forming the lids. Each processing unit is reciprocated, in linear bearings, along the conveyer so that, during each processing movement with the conveyer, the relative velocity between said unit and the conveyer is substantially zero. Each processing unit may be mounted on a shaft, which extends parallel to the length of the conveyer, and is supported by said linear bearings. The shaft may be reciprocated by cam mechanism driven by an electric motor, which may also drive the conveyer. Each processing unit may be linked temporarily to the conveyer, so as to move synchronously with it, and may then be disengaged from the conveyer and returned to the starting position, as by mechanism comprising a cam, or a spring or a pneumatic or hydraulic ram.

Relates to a combine-harvester having a cavings riddle 1 through which air is blown obliquely by a fan 2, there being a grating 3 at the rear end of the riddle permitting unthreshed ears to fall into a collecting compartment 4 from which they are returned to the machine through the action of an ejector fan 5. According to the invention the discharge opening of the ejector fan leads into a return duct 6 which passes up over the cavings riddle and opens below a downwardly facing plate 9 which is fastened to the wall 7 of the harvester-body. The base of the collecting compartment 4 slopes towards the faninlet.

Abstract: 1,067,337. Ink - ribbon mechanism. ADDRESSOGRAPH MULTIGRAPH CORPORATION. Oct. 13, 1965, No. 43465/65. Heading B6F. Ink-ribbon feed.-An ink-ribbon feed comprises an intermittently operated rotatable feed drum 35 contacting the ribbon, a pressure roller, Fig. 3 (64), a ratchet-and-pawl mechanism 111 to draw the ribbon R from a frictionbraked supply spool 17, and a delicate let-off or jockey device 155, 157, 169. 171 arranged to lengthen the ribbon by an amount equivalent to each intermittent feed. The ribbon is a light " once-only " ribbon feed across a printing plate P and below a platen 15. The feed is derived from the printing machine by a link 109 which oscillates a pawl (121) of the ratchet mechanism. Fig. 6 (not shown), connected to a gear 119 rotating a small gear on the pressure roller shaft 63. The pressure roller comprises a resilient surface and is movable to a non-operative position for threading the ribbon. The pressure roller 64 is spring mounted and the pressure is adjustable by a mechanism (81, 85); it has a carbon scraper blade (97) and a carbon collecting tray situated below. From the drive and pressure rollers 35, 64 the ribbon is guided over rollers 175, 177 and a second jockey device 195 keeps the ribbon taut while the take-up spool 23 winds up the used ribbon. The spool 23 is continuously driven through a friction clutch during a feeding operation. Brakes.-An adjustable friction brake, Fig. 4 (not shown), stops the feed rollers from spinning and a brake 161, Fig. 1, operated by a light, long spring 165 acts directly on the ribbon on the supply spool 17. Adjustable feed.-The amount of ribbon feed is adjustable to suit the size of the printing area by a shroud (133), Fig. 6, having a cam surface (135) which controls the amount of engagement the pawl (121) has with the ratchet-wheel 117. The shroud is manually adjustable by a knob 143 and rod 141 having a pointer 147 addressing a scale 145.

Title: Improvements in the treatment of waste pickle liquors
IPC: C01G49/08
Filed: 1963-11-05
Abstract: Iron oxides, particularly magnetite, are obtained together with calcium sulphate from waste pickle liquor containing iron sulphates by mixing it, with agitation, with a lime slurry in proportions such that a pH of 7 to 8 is maintained in the mixture and oxidizing the neutralized mixture.  Magnesium oxide and/or hydroxide may be substituted for lime.  Neutralisation and oxidation are carried out over a period in toto of at least 4 hours and at a temperature of 180 DEG  F. to the boiling point and the solid and liquid contents are separated from each other, at least the mixing and oxidation steps being carried out continuously.  Oxidation may be by bubbling in of air or of oxygen and may be conducted in a separate vessel from the neutralization step.  Temperature control may be effected by introduction of steam.  The solid contents may be removed by allowing the mixture to settle and decanting the liquid, which may contain only 2 p.p.m. of iron, or by filtering or centrifuging and may contain 90 to 95% solids, comprising 75 to 90% of dihydrated calcium sulphate particles and a balance of iron oxide particles comprising up to 100% magnetite as dense agglomerates, which may be removed by a conventional magnetic separator. The calcium sulphate obtained is substantially orthorhombic.

Title: Production of crystalline semiconductor materials
IPC: C01B25/06
Filed: 1966-09-29
Abstract: <PICT:1110488/C1/1> Crystalline semi-conductor material is prepared by a method comprising reacting the components in a substantially horizontally disposed tubular crucible to synthesize the semi-conductor material, turning the crucible into a substantially upright position and subjecting the melt to unidirectional freezing. The process is carried out in an apparatus as shown in Figure 1.  The arrangement consists of three furnaces 11, 12, and 13 have a common axial bore within which is disposed the crucible 8. The cross-section of the crucible may be circular or triangular and the crucible may have a recess or constriction 31 between its ends whereby part of the crucible to one side of the recess constitutes a melting boat during the synthesis.  The two components of the semi conductor material are placed into the crucible which is then sealed under a high-vacuum. Heat from the furnaces melts the components and then the apparatus is turned into a vertical position so that the melt may be subjected to unidirectional freezing, from the bottom upwards by vertical movement of the furnaces, especially furnace 13.  After crystallization by unidirectional freezing, the crudible may then be turned back to the horizontal position.  The method is applicable to the preparation of indium phosphide and arsenide, gallium arsenide and mercury telluride.

Abstract: 1305487 Increasing lift on aircraft R A MAYER JNR 21 Sept 1970 [25 Sept 1969] 44842/70 Heading F2R An aircraft is provided, on an exterior surface, with a plurality of slots substantially parallel to the normal direction of motion, and with means for generating a flow of air and directing it to said slots. For example a wing 2 may be provided with ribs 10 each having a central aperture 11 so that the wing contains a chamber made up of a plurality of sections 13, each bonded at its upper limit by an inclined baffle 14 which, together with wing surface 7, defines a discharge chamber 15. Ambient air is supplied to the wing from pressure chamber 8, which may be supplied either from the engine 5 or by separate blowers, and passes to each discharge chamber 15 by way of inlets 16 in the ribs and is emitted over the upper surface of the wing through elongated slots 17, thereby producing or increasing lift. Each slot may be provided with deflectors (18), Fig. 4 (not shown), extending inwardly into the respective chamber 15 and inclined towards the edge of the wing, thus tending to confine emitted air to the centre of the wing and prevent spillage over the edges, and it is possible to vary the area of the slots 17 throughout the length of the wing in order to achieve a constant air velocity. Similar slots 20 may be provided on tailplane 19, and further slots 22 in the upper part of the aircraft nose, which may be supplied in such a manner as to control pitch roll and yaw. Additional slots may be provided on the lower surface of the tailplane or on any part of the fuselage.
