Abstract: 504,990. Shank stiffeners for shoes. MUSEBECK, G. E., and MUSEBECK SHOE CO. July 23, 1938, No. 21920. [Class 17 (ii)] The outer edge of a shank stiffener for boots and shoes beneath the fifth metatarsal and cuboid bones has greater stiffness than beneath the remainder of the foot to provide normal support for the base of the fifth metatarsal when this loses contact with the ground due to elevation of the foot by a shoe heel. The shank stiffener may comprise a metal plate 10 extending from the metatarsus, where it is curved to support the arch, to rearward of the heel breast. It is stiffened at its outer edge by a reinforcing member 17 which rests in a longitudinal groove 16 in the upper face of the stiffener and which is extended rearwards and flattened and perforated for attachment to the insole or sole.

Filed: 1962-06-08
Abstract: 958,326. Electric correspondence control systems. COMMUNICATIONS PATENTS Ltd. June 8, 1962, No. 22243/62. Heading G1N. [Also in Division B7] The control member'of a ground-based flight trainer is loaded to simulate the feel during actual flight, using a displacement transducer and an accelerometer to determine the basic value of the load, these signals being modified in a computer by factors representing the simulated flight conditions. As shown (Fig. 2) movement of the control column produces a signal from a displacement pick-off which is modified in a flight computer in accordance with the static forces, e.g. friction, elasticity, Mach number, etc. This is fed into an amplifier A together with a signal from an accelerometer, and opposed by the signals from the displacement pick-off of a hydraulic servo-motor, and from a force transducer measuring the load on the control column. The output from amplifier A is fed through a phase-sensitive rectifier to produce a D.C. signal energizing the servomotor. The accelerometer output signal may be modified by shaping circuits to give a desired loading variation, simulating the inertial effects of the control mechanism and the mechanical assemblies coupled to it.

Title: Improvements in or relating to the purification of selenium
IPC: C01B19/02
Filed: 1948-08-24
Abstract: A solution of impure selenious acid is purified by precipitation therein of an adsorbent, e.g. a basic aluminium compound, such as aluminium hydroxide, or ferric hydroxide.  Thus crude selenium is oxidized to selenium dioxide, which is dissolved in water.  The pH of this solution is adjusted to 6 or 6.5 by adding ammonium hydroxide and aluminium sulphate solution is then added.  After standing for 24 hours the supernatant liquid is removed, and the selenium recovered by passing sulphur dioxide through the warmed filtrate.  The precipitation of the adsorbent is preferably effected in the presence of sulphide ions, e.g. by adding ammonium sulphide liquor before the precipitation.

[Also in Divisions B1 and F4] Packing material for use in transferring heat or moisture between two fluids (e.g. in cooling towers) is composed of sheets of asbestos fibrous material bearing against one another at mutually spaced places and therebetween forming passageways extending throughout the packing, at least part of an external surface of the sheet material being covered with inorganic substance which is fused to solidify it on to the fibres to increase the hardness of the sheet structure. The sheets may be alternatively plain and corrugated and may be bonded together, e.g. by water glass; they may contain organic binders which are subsequently driven off by heating. The covering substance may be one or more kinds of enamel or other ceramic particles applied in powder form or as a dispersion and may be applied to the asbestos fibres before, whilst, or after the asbestos is being formed into sheets, being subsequently fused after the sheets have been put together to form packing. Additional substances, e.g. to increase penetration into the fibres may be present. For some applications the covering substance may be metal which may be sprayed on to the outer faces of the packing. Additional covering may be applied at selected parts of the sheets, e.g. the channel openings. If the packing is to be used for moisture transfer the fibres are only partially coated so that their absorbing capacity is not seriously impaired; they may be impregnated with a salt, e.g. lithium chloride. Apparatus, Fig. 1, for controlled heating of the packing 26 comprises a kiln 10 containing a heater 32 and an inner chamber 22 in which is a lattice 24 blanked-off by shields 28 to ensure that all of the hot air or other gas circulated through the chamber by the fan 34 will pass through the packing. By controlling the circulation velocity of the hot gas and by adjusting the amount of oxygen it contains by means of the inlet and outlet dampers 16 and 18, the organic binder constituents of the packing can be oxidized and the covering fused combustion being controlled without the generation of temperatures which would be harmful to the asbestos.
