Title: Disintegrating bodies
IPC: F42B8/16
Filed: 1965-07-19
Abstract: 1,103,467. Practice projectiles. K. DIEHL. 19 July, 1965 [18 July, 1964], No. 30501/65. Heading F3A. A body, such as practice ammunition, which is intended to disintegrate in use, is formed from metallic powder grains embedded in a matrix which coats the grains and disintegrates suddenly and completely beyond a predetermined stress limit. The matrix may be composed of a fatty acid metallic salt or salts with a melting-point 20% above the maximum expected temperatures. Calcium, aluminium, barium, copper, lead and zinc stearates are among those salts mentioned as suitable as well as palminates, oleates, resinates, laurates, naphthenates or telates of these metals. The powder grains may consist of a hardened metal alloy such as an iron-silicon-chromiumnickel-copper alloy and have a size range between 0À06 and 0À2 mm. The body may be made by mixing the powder with a solution of the matrix substance or substances and pouring or compressing the mix in a mould. The solvent, which may be a hydrocarbon, is then evaporated by heating, the mix then being heated to the melting-point of the matrix to coalesce the matrix around the powder grains. The resulting body may then be coated, e.g. with clear varnish.

Title: Improvements in the production of aluminium from aluminium alloys
IPC: C22B21/00
Filed: 1950-12-18
Abstract: A process for the production of aluminium from an iron-aluminium alloy having at least 10 per cent. of iron, by treating the alloy with a halide or halogen-containing substance to distill off aluminium as its sub-halide vapour or by treating the alloy with a liquid metal solvent such as zinc, is characterized in that the thermodynamic activity of the aluminium is increased by arranging that the alloy has a silicon content of at least 80 per cent. of the atomic proportion of iron present in the alloy, the added silicon being introduced as silicon or a silicon alloy to the alloy or by smelting selected material to produce an iron-aluminium-silicon alloy of the desired silicon content.  A silicon containing material such as clay may be mixed with ore containing aluminium and iron, such as bauxite, the mixture being reduced to form the alloy in which silicon is preferably present in an atomic proportion equal to or slightly in excess of the iron content.  The Provisional Specification relates generally to the production of aluminium from a material containing aluminium and an element which would reduce the activity of the aluminium, by addition of a third constituent which, by interaction with the said element, has the effect of increasing the activity of the aluminium.

Abstract: 1,041,287. Worm extruders. FARBENFABRIKEN BAYER A.G. Aug. 4, 1964 [July 31, 1963], No. 31208/64. Addition to 924,108. Headings B5A and B5B. A screw or worm extruder for melting thermoplastic synthetic resin, especially polyamides or polyurethanes, comprises a screw housing 2 provided with a heated melting zone 5, a tempering zone 6 preceding the heated melting zone in the direction of flow of the material, and a melt supply zone 8 after the melting zone, the screw housing being constructed in the region of the tempering zone as a unilaterally secured torsion member secured to the exterior of which is a lever 14 serving, in the operation of the screw, to actuate the switching-on and off contact 15 for the drive of a metering device (not shown) for the material, the screw 3 ending with its threads at the outlet end of the tempering zone 6 of the housing whilst a stirrer 16 or 17 is arranged in the melting zone. In Fig. 1, the stirrer 16 is a paddle. In Fig. 3, the stirrer 17 is a fork between the prongs of which an immersion heater is fixed. In operation, if for example, the rate of feed of material rises in relation to the rate of outflow of melt, the position of the solid-liquid interface in the worm housing will shift towards the feed aperture, increasing the torque and changing the torsion of the screw housing. By arranging that the screw ends with its threads at the outlet of the tempering zone a considerable increase in the melt output can be achieved while accurately maintaining the quantity of melt removed.

Title: Improvements in or connected with radio-navigational apparatus and the like
IPC: G01S1/02
Filed: 1919-12-15
Abstract: 160,251. Murray, J. Erskine-, Robinson, J., and Crowther, H. L. Dec. 15, 1919. Bearings, determining; heterodyne receiving systems.-In a direction-finding system of the typo in which the frequency of the transmitted wave is a function of the direction of transmission, the receiving station is provided (1) with a tuned circuit to give a heterodyne effect of high or inaudible frequency to the continuous signalling wave, and (2) with another tuned circuit on which the heterodyne effect is impressed to give a superimposed heterodyne effect of low or audible frequency. The transmitting station comprises a directive transmitter adapted to emit successively along bearings between North and South continuous waves having a different frequency for each direction of propagation. Preferably the transmitter is adapted to transmit during 180‹ of rotation only. As the frequency for each direction of propagation is known at the receiving station, by listening for the minimum transmission of the signalling wave, that is, for the wave propagated in line with the receiving station but in the opposite direction, and recording its wavelength, the bearing of a line joining the transmitting and receiving stations can be found. The receiving station comprises two tuned circuits 4, 5, and 8, 9, 10 adapted to self-oscillate, as shown in Fig. 1, or having oscillations induced therein from an independent source. The circuit 4, 5, 6 is tunable between the range of the transmitting wave, for example 1000 to 2000 metres, whilst the circuit 8, 9, 10 is tunable to a low frequency, for example 20000 to 40000. When the circuit 4, 5, 6 is tuned to the wave-length corresponding to the direction of minimum transmission, two equal heterodyne '' swells " will be produced as the signalling wave rotates about the transmitting station, but if the circuit 4, 5, 6 is not tuned to the correct wave-length two heterodyne "swells" of unequal intensities are produced. As the limit of audibility is restricted, ordinary heterodyne between the signalling wave and the circuit 4, 5, 6 could only be compared over a very small angle on either side of the minimum, where signals may be very weak. For this reason, heterodyne effects in the circuit 4, 5, 6 are superimposed on the circuit 8, 9, 10 to obtain beats of audible frequency. An audible beat frequency will thus not be produced in the circuit 8, 9, 10 until the frequency of the signalling wave has varied sufficiently to produce beats in the circuit 4, 5, 6, which are of the order of the frequency of the oscillations in the circuit 8, 9, 10. The angle at which signals are heard may therefore be widened by increasing the frequency of the circuit 8, 9, 10. Specification 149,827 is referred to.

Abstract: 1516342 Automatic control of coating "weight" USS ENGINEERS & CONSULTANTS Inc 29 July 1975 [29 July 1974] 31649/75 Heading G3R The "weight" (thickness) and distribution of coating, e.g. zinc, applied to a strip is controlled in response to the output of gauges which scan the width of the strip. Surplus coating is removed by "air" knives; the air (or other fluid) pressure is adjusted according to the error in the overall total thickness of coating (both sides), over a whole scan, and their position is adjusted by servo-motors according the gauge output at selected parts of each scan, e.g. near the edges. One end of one knife only is adjusted at a time (by a pre-set amount) after successive scans, in a pre-set sequence. The measuring gauges emit x-rays and the resulting fluorescence, which has a known relationship to the coating "weight", is detected. The control logic circuits are described in some detail; allowance is made for the transit time between the knives and, in one embodiment, for changes made in the product specification made during a scan. Typically, the scanning rate is 1 inch/sec. and signals are sent to the control logic at 0À5 sec. intervals, each corresponding to the average thickness over the previous 0À5 inch. The measuring heads are retracted more rapidly, and the control signals are derived during the retraction period, the individual thickness signals having been stored for this purpose. Each stored signal is compared with a minimum thickness reference and the average for the whole with a desired thickness reference.
