[Class 7 (v)] An admission valve 3 for starting-air is opened by fluid-pressure acting on a piston 6, only part of the force on the piston coming into operation at first and the whole force later In one form, Fig. 1, the piston 6 is mounted on the valve stem 5 and has parts 16, 17 of larger diameter and a cam-actuated valve 13 controls the supply of fluid to spaces 21, 24 above and below the piston. A passage 9 equalizes pressure above and below the enlargement 16. Fluid pressure acts first on the upper face 15 ; when this passes the edge 14 of the valve casing, fluid is admitted to act on the enlargement 16, which closes the lower end of the passage 9. The escape of fluid below the enlargement 17 ceases when the enlargement passes the outlet 18, the valve then being cushioned by air in the space 24. In modifications, (a) the enlargement 17 is omitted and the space 22 serves as a cushioning space ; (b) two simple pistons are mounted on the valve stem, the pressure fluid first acting on one and then on both; (c) one simple piston on the valve stem is acted on first by low-pressure fluid and then by high-pressure fluid ; and (d) the piston 6, Fig. 5, is mounted on a spindle connected by a lever 50 to the valve stem 5.

Abstract: 1370718 Magnetic storage arrangements GOODYEAR AEROSPACE CORP 15 March 1972 [12 April 1971] 11973/72 Heading H3B [Also in Division G4] A plated wire memory array has alternate pairs of drive wires 30a-30h pulsed in opposite directions, i.e. wires 30a, 30b are pulsed one way, wires 30c, 30d are pulsed the opposite way and so on. In prior art devices (Fig. 1, not shown) they were all driven the same way so that a wire could be accidentally driven by the fringe fields of the adjacent wires. In the present array the fringe fields are stated to cancel each other out thus allowing the wires to be more closely spaced and the bit packing density to be improved.

Patent GB-734973-A (GB)
Title: Improvements in or relating to fractional fusion methods
IPC: C22B9/02
Filed: 1953-04-30
Abstract: In a "zone-melting" process for treating an electrically conductive material, the molten zone is heated by the passage through the material of an electric current between two electrodes in contact with the molten zone.  In a process for producing pure lead for use in electric accumulator plates, an ingot of impure lead is supported in a long horizontally-disposed firebrick trough which is movable within a chamber containing nitrogen.  Two vertically-extending graphite electrodes mounted within the chamber are lowered to contact one end of the ingot and a voltage is applied between the electrodes to melt a zone having a thickness of one-tenth of the total length of the ingot, the electrodes being further lowered so that they are immersed in the molten zone.  The trough is then moved longitudinally so that the zone moves from one end to the other of the ingot. Finally the electrodes are removed so that the molten zone solidifies and the end containing impurities is cut off.  The molten zone may be agitated mechanically or by ultra-sonic waves and the solid parts of the ingot on either side of the zone may be cooled to limit the thickness of the zone.  Further pairs of electrodes may be provided so that several zones are formed.

Title: Improvements in and relating to the treatment of starch
IPC: C08B30/12
Filed: 1943-07-26
Abstract: A starch preparation suitable for use in coating paper is obtained by treating a raw starch milk derived from cereal or root starches with a diastatic enzyme at a temperature below the gelatinising temperature of the starch so that about 10-20 per cent of the starch is rendered soluble, separating the insoluble portion and further modifying it to give a thin boiling starch. The raw starch milk which may be a 22 DEG  Baum<\>ae suspension with a pH adjusted to 4.5-6.5 is treated at 120-135 DEG  F. for 18-30 hours with a diastatic enzyme such as Vanzyme (Vanderbilt) and the starch residue filtered off and washed.  It is then further treated, either with an enzyme such as Amyliq (Wallenstein), Vanzyme (Vanderbilt) or Diastase (Rohm and Haas) at a pH of about 7 at 164-170 DEG  F. for a period of time up to 30 minutes, after which the enzyme is killed by raising the temperature to 205 DEG  F. and then cooling; or by chemical agents such as peroxides, chlorine or acids.  The resulting thin boiling starch which should preferably be used freshly may be incorporated with a china clay suspension containing a dispersing agent such as sodium pyrophosphate in the proportion of 12-15 lbs. of starch to 100 lbs. of clay and then applied directly to the paper.
