Patent GB-965763-A (GB)
Title: Improvements in or relating to a method of rapidly producing metal powders of high purity
IPC: C22B5/00
Filed: 1960-11-02
Abstract: Metal compounds such as oxides are reduced to metal powder by adding a solid organic reducing agent and heating the reducing agent and metal compound in a gaseous reducing agent to bring about reduction until no solid reducing agent remains and then continuing the heating in the gaseous reducing agent until the metal compound is completely reduced. The reduction of higher oxides and ammonium compounds of molybdenum and tungsten is particularly referred to, as is the use of hexamine, fats, waxes and starch as solid reducing agents.  As gaseous reducing agents hydrogen, carbon monoxide and ammonia may be employed. Alternatively the reducing atmosphere may be that resulting from vaporization of the solid reducing agent.

The first pair in the sequence provide a motive fringe pattern with light outputs along certain  directions, i.e. a set of collimated sources, while the second pair provide a second motive fringe pattern with a light output which depends for its intensity upon the degree of reglster of the transmissive directions of the second pair with those output directions of the first pair, the transducers thereby, as the elements of the second pair are moved relative to one another with the member, receiving a sinusoidal signal of light intensity, the signal being derived from the integration of the outputs along several transmissive directions of the second pair. The gratings may be four in number and arranged discretely along the path or, as shown in Fig. 8 two of the gratings may be formed on each side of a plate 63 of transmissive material which plate is moved in the direction of the arrow whereby the pair A experiences movement in a first sense and pair B in a second sense to increase the resolution of the system by a factor of 2. A single pair of gratings 91, 93, Fig. 9, may be provided and the light path may be arranged to pass through different regions of the pair by means of a mirror surface 97 on the rear face of the carrier of grating 93. This latter system may be modified so that the second element of the second grating pair traversed by the light is composed of 4 sub-gratings arranged in quadrature so that directional information of the move - ment may be obtained. The peaks of the alternating waveform are connected electronically to measure the movement.

Abstract: 1515308 Lasting shoes BRITISH UNITED SHOE MACHINERY CO Ltd 1 Sept 1975 [31 Aug 1974] 38152/74 Heading A3B  A shoe lasting machine of the type in which powered wiping rolls 2, Figs. 1, 2, having helically ribbed working faces are moved relatively to a lasted shoe assembly, has a guide 100, &c to engage a shank S secured to the shoe assembly and thus align the shoe assembly between the rolls. The guide 100 acts through automatic control mechanism to raise side clamps 30, Figs. 2, 3, to a height corresponding to that of the shoe assembly before the side clamps grip the shoe assembly firmly. A movable carriage 10, Fig. 1, mounts pivotally a jack post 12 raised to the operative position shown by a servo, a heel band 16 then engaging the shoe assembly. The guide 100 is a grooved roller which runs along a rib 104, Fig. 2, of the shank S as the jack post 12 is raised. The grooved roller 100 is journalled in an arm assembly 120 pivoted about pins 122 in the machine frame and biassed to the operative position by a pneumatic servo. In moving from its inoperative, withdrawn position to the extended position shown and before raising the jack post 12, the guide roller 100 runs down the back of a hold-down 24. As the jack post 12 raises the shoe assembly to the operative position, the roller 100 can rise also against the biass of the servo 130. The guide roller 100 thus senses the height of the shoe assembly. An arm 118, Fig. 3, of the arm assembly 120 carrying the guide roller 100, is engaged by a nose 181 at the end of a sensing arm 180 biassed to turn about its pivot 182 by a servo 190.
