Abstract: 1378092 Tabletting machines UP JOHN CO 10 Oct 1972 [16 Nov 1971] 46692/72 Heading B5A [Also in Division G3] In a machine for making compressed articles, e.g. tablets, in a mould, in which the quantity of material in the mould is controlled in response to electrical measurement of the force exerted during compression, means are provided for disabling the control system when the measured signal is below a prescribed value (indicative of an insufficient supply of material. A table carrying a plurality of dies 13 moves in the direction of the arrow A. The dies are filled on the right hand side; the quantity is controlled by adjustment of a cam 152 which raises plungers 12 to eject surplus material which is removed by a scraper 153. Compression takes place on the left between two plungers 11, 12 actuated by rollers 19, 28, the position of the lower one being manually adjustable at 33. The upper roller is held by a link carrying a strain gauge 38 in a bridge (which may be wholly in the link), the output of which is amplified at 63. The output of the amplifier is smoothed at 74 and is measured by a meter 82 whose pointer 84 operates contacts in relay circuits 88, 89. The sitnal to the meter is limited for safety by diodes 96. The meter relays control contacts ML, MH in the circuit of a reversible servo-motor 154 which adjusts the cam 152 in the appropriate direcion when the force exerted by the plungers exceeds upper or lower limits (due to too much or too little material in the mould). Push switches S1 S2 provide manual operation of the servomotor. Also in series with the motor circuit are the contacts AR of a further relay 108 which is energized via a thyristor 109 triggered by the output of the amplifier 63; thus, if this drops below a prescribed value (due to insufficiency of material supply) tiggering does not occur and no cam adjustment is made, thereby eliminating the need for re-setting when the material supply is restored. While the servomotor is operating, triggering signals are applied to a second thyristor 117 (with a Zener diode 146 to limit trigger voltage) in series with a 3 second thermal delay 114. When this times out an alarm 116 is sounded. Another delay circuit 121 disconnects the supply if correction continues for 60 seconds. The machine may be similar to that described in Specification 1,152,061.

[Also in Division B3] In a process for cold rolling metal strip or sheet, the lubricant used during rolling is subsequently irradiated to form a protective coating on the metal. In an example, a strip. 2 is coated with lubricant as it passes between the rolls 4 of a cold rolling mill, the lubricant conveniently being sprayed on the rolls. The lubricant is then dried and spread uniformly over the strip by passing the strip through an oven 6. The strip is irradiated, in a vacuum chamber 8 provided with roller seals 14, by means of electron beams, X-rays or gamma rays. The lubricant coating is cross linked or polymerised to form a protective coating on the metal. The lubricant may be a rolling oil, liquid paraffin, palm oil, polyethylene, or dioctyl sebacate. A second coating may be applied to the strip following partial or full irradiation of the initial coating. The second coating, which can be vacuum deposited epoxy resin, can then be similarly irradiated. Alternatively, the second coating can be deposited on the initial coating before irradiation of both coatings.

Abstract: 1,169,056. Making pistons; altering physical properties. ALUMINUM CO. OF AMERICA. 18 Oct., 1967 [25 Oct., 1966], No. 47523/67. Headings B3A and B3V. [Also in Division C7] The fatigue strength of an aluminium or aluminium alloy casting is improved by subjecting the casting to a substantially isostatic pressure of at least 3000 p.s.i. while maintaining the casting at a temperature of at least 600‹F. but less than the melting point of the metal for a time sufficient to render the casting substantially free from micropores over 0À0001 inch in size. Tensile strength also is improved, and pressures up to 100,000 p.s.i. and temperatures up to 1000‹ F. are referred to. Application times range from several seconds to more than an hour. The pressure may be applied by dies or fluid, e.g. helium gas. A casting may be quenched immediately after treatment, followed by an artificial ageing. Alternatively, a separate heat treatment may be applied after the isostatic pressure treatment. A rough sand casting may be machined, improved by the isostatic treatment, heat treated and then finish machined. In an example, an aluminium alloy piston casting including 4¢% Cu, 1¢% Mg and 2%Ni, was heated to 850‹ F. and placed in a preheated die. A ram was forced against the piston for 1¢ minutes at 47,000 p.s.i. In a further example the piston had a Ni-Fe ring insert. In another example specimens from an aluminium alloy casting containing 9% Si, ¢ Mg and 1À8% Cu were treated isostatically, after which they were reheated to 980‹ F. for 8 hours, quenched in water at 150‹ F. and artificially aged for 10 hours at 310‹ F.
