Filed: 1974-09-11
Abstract: 1521034 Stretched extruded nets NETLON Ltd 27 Aug 1975 [11 Sept 1974] 39546/74 Heading D1R A plastics mesh in which each opening is 4 sided is stretched so that the strand intersections are deformed to form 2 sides 2a of a hexagonal mesh with original sides 1a and newly formed sides 2a of confluent portions of pairs of strands 1a, all molecularily orientated along their length. The length of each strand 2a is at least 2 preferably 3.5 times the diameter of a national circle of area equal to the cross sectional area of the strand 2a at its midpoint. The quadrilateral starting mesh is formed by extrusion with the intersections formed before or as the strands are extruded, or by adhesive bonding of the strands where they cross. Preferably the mesh is tubular and formed from a counter-rotating concentric pair of circular dies having spaced orifices. Polyethylene, polypropylene, polyamide and polyester resins are specified. In one embodiment the starting mesh in rope (bunched) form is stretched in the machine direction to lengthen and orient the strands 1a, but leaving the intersections unstretched. The mesh is then stretched in the transverse direction to elongate the intersections into strands 2a extending in the T.D. Finally the mesh is M.D. tensioned in rope form. In a second embodiment the mesh in rope form is M.D. stretched to orient strands 1a and elongate the intersections into strands 2a, followed by T.D. tensioning. In the third embodiment the directions of the second embodiment are interchanged. The stretching of the intersections yields a lighter net with a softer feel.

Title: Process for purifying nickel sulphide
IPC: C01G53/00
Filed: 1966-09-06
Abstract: Nickel sulphide may be purified from copper, cobalt, iron, lead and arsenic by selective chlorination of the impurities using gaseous chlorine at 400-700 DEG  F.  The mixture is then cooled and the impurities are leached out.  The cobalt chloride may be leached out with water. Chlorine water or ammoniacal ammonium carbonate solution may be used to leach out the impurities. Generally, leaching with water is followed by leaching with chlorine water or ammoniacal (NH4)2CO3.  Chlorine is used, diluted with an inert gas, in amounts of from 1 to 4 times that required to completely chlorinate the impurities.  The reaction may be carried out in a rotary furnace, a suspension roaster or a fluidized bed.  To avoid unduly high solution of nickel chloride formed the redox potential of the solution of chlorine water is maintained between +400 and +600 millivolts whereas, if ammoniacal ammonium carbonate is used the redox potential is maintained at below +200 millivolts and may not be used to remove iron.

Abstract: 1,076,044. Feeding webs. DIAMOND NATIONAL CORPORATION. Oct. 2, 1964 [Dec. 5, 1963], No. 40255/64. Heading B6B. A web is passed in over a roller (20), Fig. 1, and between slitters (28) and driven drums (52, 54) to a roll core (50) which rests on the nip of the drums to be rotated thereby and form a roll (R). The core is vertically slidable between guides (98), Figs. 3a and 6, which are swingable by fluid motors (90) between a slightly retracted position, Fig. 6, and a position against the core bearings. A bar (144) co-operating with a scale to indicate roll diameter rests on the roll (R) and is slidable on bars (136) a block (138) carrying the bar engaging limit switches to start the drive of the drums when in the lowest position and stop the drive when the roll reaches the required diameter. Resting on the roll is a two-section rider roll (226), Figs. 1 and 11, carried on three arms, (218, 222) at the ends and a third at the centre, pivoted on a shaft (216) carried by a beam (190) vertically slidable by the rotation of screws (192, 194) by a motor. The beam carries six abutment portions, one extending in each direction over each of the three arms as (218), such as shown at (228, 232, 238). Each abutment portion is connected to the underlying arm by a pneumatic diaphragm, such as shown at (240, 242, 246, 248), the left-hand diaphragms being controlled to counter-balance the weight of the roll (226). Initially, the beam is lowered until the roll (226) rests on the core (50) with the arms as (222) pivoted downwardly to position (222<SP>1</SP>). As the roll (R) increases in diameter, the arm is forced up to position (222<SP>11</SP>), closing a switch (274), whereupon the beam is raised, thus allowing the arm to drop again, opening a switch (272) to stop the beam drive, this operation being repeated continually.
