Abstract: 1,230,794. Silica of reduced water content. O. W. BURKE, Jnr. 24 April, 1968, No. 19344/68. Heading C1A. Wet silica pigment having a free water retentivity (defined) of 0À8-3 parts/part SiO 2  is derived from a pressed cake which breaks up into polygonal prisms and which may be made by applying a pressure to opposed surfaces of a body of precursor wet silica pigment to express the desired amount of water and impart the polygonally cracked structure thereto. The precursor pigment is one precipitated from an aqueous solution of an alkali metal silicate, e.g. with a 20% excess of CO 2  over that required to form carbonate. The pigment body may be enclosed in a foraminous or reticulated support, e.g. a filter cloth, placed in a press and a pressure of 50-1000 p.s.i. applied. In some examples, the precursor pigment was slurried in the presence of H 2 SO 4  and possibly also aluminium sulphate and subjected to shear with a propeller agitator prior to filtering (e.g. at a N 2  pressure of 200 p.s.i.) and pressing.

Abstract: 1,253,142. Stock feeders. A. W. SCRIBNER. 13 Jan., 1969 [20 Sept., 1968], No. 1863/69. Heading B3W. In an intermittent stock feeder in which a fluid pressure operated gripper 25 is mounted on a fluid pressure-operated feed slide 24 reciprocable through alternate feed and index strokes, a valve unit 80 for controlling the operation of the gripper and the feed slide is moved bodily to clamp the stock against retrograde movement when force is applied to a piston-rod 86 to cause an index stroke of the feed slide. The slide is mounted on the pistonrod 22 of a fluid pressure cylinder 16 which is adjustably mounted on a rod 12, the head 72 of a guide screw projecting from the slide engaging in a groove 73 in a parallel rod 11. The slide is returned by a spring 33. The gripper 25 comprises an arm 34 pivoted to the slide by means of a stud 35, a fluid pressure piston 41 acting on one end and the other end overlying the stock, upward movement of the arm being limited by abutment against a thrust washer on the underside of the stud head. The slide also carries an impact buffer cylinder arrangement 45. Pressure fluid is supplied simultaneously to the three cylinders through a single conduit 60 via the valve unit 80 which is mounted on the vertical arm of a bracket 91 adjustably mounted on a block 13 of the feeder frame. Pressure fluid continuously supplied to the valve cylinder 84 from a supply 94 normally biases the valve member 85 upwardly to the position shown in Fig. 4 in which exhaust ports 110, 111 are blocked by a gasket at the upper end of member 85 and fluid passes to the conduit via a bore 114, passage 115 and annular passage 116 to actuate the gripper 25, advance the slide 24 in a feed stroke and advance the buffer piston-rod to the cushioning position shown, Fig. 1. To cut off the fluid supply the piston-rod 86 which is movable relative to the member 85 is moved downwardly, e.g. by engagement of a bolt on a press ram, a shoulder 117 on the rod first closing the passage 115 and a shoulder 120 then engaging the gasketed upper face of the member 85 to lower the member and put the conduit 60 in communication with the ports 110, 111. The impact on the rod 86 causes the valve unit to move bodily downwards to clamp the stock, the unit rising automatically when the rod 86 returns to the Fig. 4 position. The preferred fluid pressure medium is air. In another embodiment the gripper is actuated by a combined pneumatic/hydraulic piston and cylinder arrangement. The valve unit may be mounted on the bed or ram (Fig. 7, not shown) of a press to which stock is being fed.

Abstract: 1,257,306. Measuring thickness electrically. AGFA GEVAERT. March 11, 1969 [April 11, 1968], No. 17621/68. Heading G1N. The resistance and hence the relative thickness of transversely spaced longitudinal zones of an electrically conductive web or coating is measured by passing an A. C. current through the strip via an electrode e.g. a roller 12 and a plurality of electrodes 15 e. g. a split roller 13 and measuring the current in the circuit the electrodes 15 being connected to a common point and the potential difference between the electrodes 15 and the common point being maintained substantially zero. As described, the method has application to the coating of a liquid film on an insulating strip. A zone is selected in a unit 19, Fig. 5 (not shown) and a rotatable switch connected in a circuit, Fig. 5 (not shown) mounted inside the roller 13 is caused to rotate until the selected section of the roller 13 is connected to a recorder 18. The D. C. output from the circuit inside the roller is applied to the recorder 18 which may be a strip recorder which plots the thickness profile of the coating or an X-Y recorder which automatically indicates which zone is being measured, in that case a continuously rotatable selector being used in unit 19. Alternatively an alarm or a coating application control mechanism may be operated. The absolute thickness of the coating may be determined by measuring the specific constructivity of the liquid coating before application and automatically dividing this into the resistance values obtained for the respective zones, Figs. 6 and 7 (not shown).
