Title: Process and apparatus for the manufacture of tiles
Inventor: BUCHEL A
IPC: B28B3/20
Filed: 1972-02-24
Abstract: 1374858 Moulding plastic substances, &c. INTEROPTIK HANDELSANSTALT 24 Feb 1972 [1 March 1971] 8667/72 Heading B5A [Also in Division F2] Tiles 5 are formed by extrusion of clay, Fig. 1, between a plurality of relatively adjustably spaced die blades 2 of a die 1, into a plurality of vertically juxtaposed layers 3 between which, as the layers move into contact at 8 on leaving the die, a powdered release agent is injected and to the upper and lower exterior surfaces of which is applied impermeable sheets 39, 40, which act to prevent excess evaporation from these surfaces and consequent warpage of the exterior layers; during drying subsequent to the cutting of the layers by a knife 4 to form stacks of juxtaposed tiles 5. The sheets 39, 40 preferably comprise aluminium, oiled paper, or regenerated cellulose and are removed by combustion during baking of the tiles, together with the release agent, e.g. comprising polyvinyl acetate and polyvinyl alcohol powder, which, after drying, acts to temporarily adhere the layers to facilitate transportation. The die 1, Fig. 3 is provided with upper and lower members 12 which are of adjustable inclination, by screws 13, to regulate the lateral flow of the clay between the blades 2. The spacing between the blades 2 is fixed at their downstream ends by steps 15 of the blades 2 locating in notches 14 of the die outlet. The adjustment of the blade spacing, to ensure the same flow between all blades 24-27, is effected at their upstream ends, by engagement of nuts 33-35, Fig. 4, carried by the blades 25-27, on both sides of the central blade 24, with threads 30-32 of concentrically arranged shafts which are simultaneously or independently manually rotatable from the exterior of the die. The shafts on both sides of the central blade 24 are engaged at 36 with the central blade 24, and the threads 30, 31, 32 are of progressively increasing pitch, e.g., in the ratio 1 : 2 : 3 to provide a progressively decreasing adjustment towards the central blade 24 upon simultaneous rotation of the shafts. The nuts 33-35 are mounted within blade notches 37, Fig. 3, by clips (38), Figs. 5 and 6 (not shown), which are of U-section in planes parallel and transverse to the blades.

Stereogrammetric apparatus.-In hand plotting machines for survey photographs in which the motions of the measuring device takes place in two planes at right angles, the movement are distributed so that motion of the image carriers takes place in one plane and the motion of the inlet reflectors of the measuring telescope in the other plane. This is effected by the provision of an intermediate body 14 which is slidable along an axis 3 without rotation, by which movements may be transmitted to the reflectors in a vertical plane. The guide 1 is pivoted to the lever 12 and mounted in a frame 1 in the vertical shaft 3 by which the image carrier is rotated about the front principal point of the lens 9 and may be clamped in position on the lever 12 by the nut 13. The vertical component of the movement of the guide 1 is transmitted by lever 12 intermediate body 14 and lever 17 to the reflector 20 and the horizontal component is transmitted to the image carrier 2 by the axle 3, as shown. The points of contacts 22, 23 of the movable body 14 with the levers 12, 17 are equidistant from the vertical axis 3. The lower part of the body 14 consists of a circular ring against which the lever 12 bears, and is at right angles to the axis. A spindle 15 is fitted to prevent rotation of a body 14.

Abstract: 1,174,963. Discharging molten metal. AJAX MAGNETHERMIC CORP. 24 Feb., 1967 [11 March, 1966], No. 9038/67. Heading F4B. [Also in Division G3] In a furnace for supplying a pouring device with molten metal, a storage chamber supplies a smaller exit chamber the level in which is maintained constant by automatically controlling the pressure in the storage chamber in dependence on the level in the exit chamber. In Fig. 1, molten metal is supplied from a remote melting furnace (not shown) through a runner 11 to an entrance furnace 10 from which the metal flows through a conduit 12 to a large capacity holding furnace 13. From furnace 13 the metal flows through a conduit 14 to an exit furnace 15 which supplies single and multiple orifice pouring devices through runners extending sideways from the top of the exit furnace. The furnaces and runners may be heated by electric induction and three electrodes 22, arranged at different levels in the exit furnace, maintain the level in that furnace between limits by controlling solenoid valves 28, 29 so that air pressure in the holding furnace is either increased by coupling a fan 25 or decreased by venting to atmosphere at 30. The entrance furnace may be dispensed with and the holding furnace may also be the melting furnace.

Title: Wire and rod plating process and product thereof
Inventor: MANSON WALTER J
IPC: C25D7/06
Filed: 1961-03-13
Abstract: 938,192. Electrolytically coating wire, rod or strip. KENMORE FOREIGN CORPORATION. March 13, 1961, No. 9104/61. Class 41. To produce a pore-free and crack-free metal coating on wire, rod, or strip, the wire, rod, or strip is firstly electroplated, secondly coldworked, e.g. by drawing through a die or rolling, and thirdly further electroplated. During the first plating the wire, rod, or strip, is passed in and out of the electroplating bath at least ten times to deposit a series of layers at least 0.0005 inch thick thereon. The second plating also results in a series of layers at least 0.0005 inch thick. The core of wire or rod may be Ni, Fe, Cu, Al, steel or alloys of these metals and the metal to be plated may be Zn, Sn, Cu, Ni, Ag, Fe, brass, alloys of these metals or bronze. The same or different metals may be used for the two electroplating steps. As shown in Fig. 2, wire 10 is pulled through a die 31 and then formed into a helix which is fed through a series of treatment baths 70 to 80. In one example, drawn steel wire passes through the following baths in sequence: alkaline aqueous cleaning, rinsing, sulphuric acid, rinsing, copper cyanide plating, sulphuric acid, acid copper sulphate plating and washing baths. The wire is then fed through another similar apparatus wherein it is drawn in a die, cleaned and rinsed, acid treated and then plated, e.g. in a sulphuric acid-CuSO 4  bath. The alkaline cleaning is in a bath containing 8 oz. per gallon of a sodium phosphate and carbonate composition at 180‹ F., the wire being made the anode at a current density of 50-75 amps. per sq. foot of wire surface. The copper cyanide bath consists of an aqueous solution of copper cyanide, sodium cyanide and sodium carbonate and may be operated at 25 amps. per sq. foot of wire surface. In another example, Ni instead of Cu is electroplated on to the drawn product, the bath comprising H 3 BO 3 , HF and nickel carbonate at pH 3.6-3.8 and 104‹ F. Plating may be in three or more steps with cold working between successive plating steps. The product can be further cold worked after the final plating step. Specification 775,769 is referred to.
