Title: Dispersion strengthening of lead
Inventor: ROBERTS DAVID HENRY
IPC: B21C23/01
Filed: 1962-05-21
Abstract: Dispersion strengthened lead is produced from partly oxidized lead powder by extruding it with an extrusion ratio, e.g. 20: 1, such that the oxide coatings on the powder particles are broken up into fragments which are distributed throughout the lead which has become welded together, without subsequent rolling.  Prior to extrusion, the lead powder is preferably subjected to a mechanical process, e.g. vibration ball milling, whereby the oxide coatings on the particles are broken up into fragments which are forced into the particles, while further oxidation takes place on fresh surfaces, e.g. by continual changing of the air or oxygen in the ball mill.  The process is also applied to lead base alloys, e.g. cable sheathing alloy 98.2% Pb-0.8% Sb.  Specification 892,597 is referred to.

In a device for registering electric pulses in a calculating or like system which operates with series-mode binary pulse signals, comprising a chain of elementary memory circuits, each of which is capable of registering the pulse or pulses, if any, occurring in one or more definite code-moments and has a closed circulation loop including a pulse-regenerating stage 1, controlled by reshaping pulses, and a delay element 6, the memory circuits being interconnected by controlled transfer connections or switches for progressively shifting the registrations in these circuits in at least one direction along the chain, each memory circuit includes a controlled circulation-interrupting transfer connection or " maintaining switch " 10 in the closed loop and separate from the regenerating stage. In the device shown in Fig. 2, the regenerating stage 1 comprises a triode having the circulating positive pulse or pulses applied at 3 to its control grid and reshaping pulses applied at 4 to its cathode. The positive output obtained at 5 from a polarity-inverting transformer (Fig. 4, not shown) in the anode circuit of the triode may be tapped off at 16 and is recirculated through the delay 6 and switch 10 to the point 3. The complementary output also may be obtained on a second tapping-off channel 16. Right and left shift connections 19, 20 include further normally inoperative switches 7 and 17 respectively.

These control voltages are obtained from further coincidence gates, Fig. 8, controlled by right and left shift control stages 50 and 51 similar to the stages 1. Normally the outputs Ad, Ag of stages 50, 51 are negative and a positive voltage A is obtained by applying the complementary outputs Ad, †g to rectifiers 54, 55 of the gate 54, 55, 58.
