Title: Production of shaped articles
IPC: B03B7/00
Filed: 1972-02-08
Abstract: 1405587 Board manufacture NATIONAL RESEARCH DEVELOPMENT CORP 13 July 1972 [21 July 1971 8 Feb 1972] 34243/71 and 5817/72 Headings D2A and D2B [Also in Division B5]  A board making process comprises depositing a layer of an aqueous slurry comprising a mixture of a fibrous waste material and a mineral waste material and controlling the water content of the slurry so as to produce a coherent agglomerated layer having a degree of wet strength, and then forming the layer under heat and pressure. The aqueous slurry may be deposited upon a liquid permeable support from a hopper or an extruder having means for discharging the slurry at a predetermined rate. The liquid permeable support may be an endless moving belt of metal or plastics mesh or gauze. The water content of the slurry may be regulated by means of a series of pressure rolls, by vacuum e.g. employing a cylindrical vacuum filter, by passage between top and bottom belts moving between converging fixed plates, (Fig. 3 not shown), or by drying. A plurality of formed agglomerated layers may be superimposed one on the other and laminated, or a single agglomerated layer may be formed and further layers deposited thereon by means of hoppers or extruders to form a composite which is then pressed to obtain a laminated agglomerated layer. Forming under heat and pressure may comprise moulding or passage between pressure rolls. The boards may be embossed. The fibrous waste material may be cellulosic fibres derived from waste paper, waste chopped rags, sisal, Boardmaking Apparatus. Typical apparatus for making board from papermill sludge effluents may comprise a screw extruder 3 for jute, or hessian, or nylon, polyester or polypropylene fibres, or asbestos or glass fibres. The mineral component may be a clay, e.g. china clay, an oxide e.g. silica, titanium dioxide, or antimony trioxide, or calcium carbonate. The waste materials may be derived from food, tobacco, quarry and mineral wastes, asbestos slurry wastes, and paper mill wastes. Additives such as fillers e.g. silica, quartz, limestone, pulverised fuel ash; styrene-butadiene, vinyl acetate, vinyl chloride, and acrylic resins; phenol-formaldehyde, melamine-formaldehyde, and urea-formaldehyde resins; flame retardants e.g. borates, boric acid, monoammonium phosphate and aluminium hydroxide; alum and starch; may be incorporated in the slurry. The agglomerated layer may contain a reinforcing medium e.g. glass fibres; or be laminated to on one or both surfaces with a reinforcing layer e.g. of woven hessian or glass fibre mat; or, the reinforcing medium may be sandwiched between two agglomerated layers and laminated by passage through pressure rolls. The process may be used for making insulation fibre boards, hardboards, and packaging boards. depositing the sludge effluent on an endless permeable belt, and chain-driven pressure rolls 7 for removing water from the sludge. The belt may be provided with cleaning water sprays 8 and rotary brushes 9.

Abstract: 666,559. Magnetrons. DEPARTMENT OF COMMERCE, DIRECTOR OF THE OFFICE OF TECHNICAL SERVICES OF. Feb. 27, 1948 [April 30, 1946], No. 5992/48. Class 39 (i). A magnetron with a multi-resonator anode comprising a plurality of segments is provided with a condenser, one plate of which is connected to the odd anode segments and the other plate to the even anode segments, adjustable means being provided for moving one of the condenser plates to tune the magnetron. Fig. 2 shows a fragmentary view of the anode which comprises 12 vanes 28 each of which is provided with a lower step 32, for enlarging the clearance between the anode and the upper hat 34 of the cathode, and an upper step 40 for accommodating the fixed lower plate 42 (only part of which is shown) of the condenser. The condenser plates may be in the form of discs which may be plane or corrugated and the upper plate 56 is adjustable from outside the magnetron through a bellows mechanism; the discs are connected to alternate anode segments, the connections to the upper disc being flexible if the disc is plane, and the discs thus serve to strap the magnetron as well as to tune it. Additional strapping of the normal ring type may be provided at the other end of the anode but this is generally a disadvantage. The anode structure is welded to magnetic polepieces 10, 12 and is provided with cooling fins 75.

The length of a filled patty is varied by altering the position of an end portion 6 of increased thickness on a tube 2 relative to a nozzles 5 by turning a handle 14 connected by a roller 12 and eccentric stub 13 to the tube 2 through which a filling flows; a spring biased lock 15 locks the handle in any desired position by locating in peripheral holes 17 in a plate 16. In operation, dough flows from an inlet (3) into an annular space 9 formed by the tube 2 and a body 1, eventually passing the end 6 and emerging from the nozzle, while a filling is passed intermittently down the interior of the tube 2 to be surrounded by the dough. A cutter (18) on the nozzle cuts the dough at the intervals between the filling portions. The position of the tube 2 and hence the length of patties is varied during feed of dough, which takes place at constant pressure. Various fillings may be used.

Filed: 1940-04-13
Abstract: 542,591. Photographic developing apparatus. MORSE, S. H. April 13, 1940, No. 6706. [Class 98 (ii)] Apparatus for developing with ammonia gas or a vapour produced by heating developing liquid electrically inside a developing tank of D-shape in cross-section having its curved face perforated to permit passage of developing gas to sensitive layers fed thereover, is characterised by electric heating means of rectangular form in front elevation, arranged adjacent to and following the contour of the four edges of the perforated face, and heated evenly to prevent condensation on the face. As shown, a closed tank A is supported within a box E which is also closed except at F where the layers are fed into it. The curved face B of the tank is perforated and the lavers are fed over it by a motor-driven endless belt H<SP>1</SP>. The heating coil R enters the tank at the bottom of one end beneath a curved baffle plate P of the same shape as the face B of the tank, proceeds along beneath this plate to the other end of the tank, rises up the other end in the manner indicated, proceeds back along the top of the tank above the plate, and then descends in the manner indicated back to the point of entry. Developing liquid is fed into the tank A from a supply tank N through a pipe Q having a control valve O, and drips on to the plate P just within the bottom upturned edge P2. A short baffle P<SP>4</SP> depends from this edge so that heat circulation is induced via passage T as indicated by the arrows. Condensation is promoted on the face U of the tank by a daught through passage J and outlet pipe J<SP>1</SP> produced by a motordriven fan L on the top of the apparatus; and the draught also serves to remove surplus gas from the point of delivery K of the layers. Condensed liquid runs out through a pipe V. A thermostat may be fitted in the tank.
