Title: Method and apparatus for diminishing the effects of heat, fluid flow and drag on a body
Inventor: CLARK JAMES
IPC: H01L23/34
Filed: 1969-06-09
Abstract: 1277894 Utilizing electrical energy on aircraft; cooling aircraft surfaces J CLARK 9 June 1969 29156/69 Headings B7G and B7W [Also in Divisions F2 and H1] Apparatus for diminishing the effect of heat on an aircraft body, includes a semi-conductor junction associated with a radio-active material together supported by and coverng at least a portion of said body. The junction comprises an outer P-type layer and an inner N-type layer. The radio-active material may form a layer over the semi-conductor materials, or between the body and the semi-conductor materials, or may be interspersed or diffused throughout the semiconductor materials. α- and #-rays emitted by the radio-active material ionize surrounding fluid and excite electronic, into rational and rotational states of the fluid to diminish surface friction and electrons produced on ionization induce a reverse bias across the junction which may be used as a thermoelectric generator from which electrical energy may be transmitted to equipment within the aircraft. The reverse bias reduces thermal conductivity across the junction.

Filed: 1972-06-23
Abstract: 1347610 Surveying instrument KERN & CO AG 23 June 1972 [24 March 1972] 29459/72 Heading G1F In a surveying instrument, an electro-optical telemeter comprises a transmitter 4 and a receiver 5 each having a mass distribution symmetrically disposed about the pivot axis 6 of a telescope 2. Thus rotation of the instrument about axis 6 through any angle always results in a stable position being attained. Since the extremities of the transmitter 4, telescope 2 and receiver 5 lie on a circle 7, rotation through 180 degrees is possible to allow error compensation without meeting obstructions.

Title: Nuclear reactor fuel elements
Inventor: SAUNDERS ALAN CHARLES ANTHONY
IPC: G21C3/16
Filed: 1964-07-23
Abstract: 1,081,874. Fuel elements. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. June 3, 1965 [July 23, 1964], No. 29708/64. Heading G6C. A fuel element comprises a stack of fuel members 1 and a helical coilspring 5 within a closed tubular sheath 2, the sheath having an end closure member 3 and the spring 5 being disposed between the stack of fuel members 1 and the end closure member 3 for consolidating the stack of fuel members, characterized in that the reaction of the spring is supported solely by the sheath. Two axially closed coils 6 at the end of the spring 5 adjacent the corresponding end closure member 3 are of greater diameter than the remaining axially open coils 7 and are gripped by the sheath, the remaining coils 7 being freely slidable within the sheath. The end closure member 3 has a skirt 8 with which it is secured to the sheath 2 by an electrical resistance butt weld. The spring 5 is inserted into the sheath 2 to an extent such that the outer end coil 6 is spaced from the end of the sheath and the reaction of the spring is supported solely by the frictional engagement of the end coils 6 with the sheath so that no force is exerted on the end closure member 3, thereby facilitating welding of the closure member to the sheath. Assembly of the spring in the sheath is effected by entering the coils 7 into the sheath and, when the coils 6 abut the end of the sheath, applying a clockwise torque to the spring to wind up the coils 6 into a smaller diameter so that they will enter the sheath. Upon release, the coils 6 unwind and increase in diameter to grip the sheath. The fuel element, which in the embodiment described includes a zirconium-aluminium sheath housing uranium dioxide pellets, is intended for use in a cluster of fuel elements in spaced parallel array, the elements being secured to a grid at one end to control the cluster geometry and slidably guided by a grid at the other end to compensate for thermal expansion. Spacing of the elements intermediate their length is controlled by helically wound wires on certain of the elements. One end of the wire of each fuel element is secured in a passage 17 in the end closure member 3 and the other end in a similar passage in the end closure member (not shown) at the opposite end of the fuel element.

Abstract: 1465158 Secondary radary; antennas THOMSON-CSF 5 July 1974 [7 Sept 1973] 29990/74 Headings H4D and H4A An antenna system for primary and secondary radar comprises a reflector R having square cosecant elevation characteristics, a primary feed F, positioned at the focus of the reflector and connected to the primary radar TX/RX2 via waveguide 1, and further comprising at least two probes 8, 9 positioned within feed F, whereby TX and RX signals from and for the secondary radar 15 are coupled into the primary feed; and two auxiliary radiating feeds 17, 22 located at either side of the primary feed horn 6 and connected to the secondary radar transmit side-lobe suppression signals. In Fig. 1, primary radar signals are coupled from waveguide 1 through matching waveguide 4, and emerge having polarization vector 7 into circular waveguide 5. Secondary radar signals are coupled into waveguide 5 by probes 8, 9 and dielectric slab 16, of, e.g. polypropylene so that they have a vertical polarization vector 10. Probes 8 and 9 are fed in phase opposition by hybrid circuit 13 which comprises a power divider and filter for removing any primary radar signal from probes 8 and 9. Side-lobe suppression signals are transmitted by auxiliary feeds which comprise dipoles (171, 172, Fig. 5, not shown) arranged in a polyester glass sealed housing having a metal reflecting plane (173). The polar diagram of the feeds 17, 22 (Fig. 3, not shown) shows how their main lobes suppress the secondary lobes of the primary feed. In another embodiment, (Fig. 2, not shown) the primary radar signals are circularly polarized and the secondary radar signals are ellipitically polarized. The secondary radar is equipped with a diplexer (130), having absorbent loads (131, 132) for dissipating primary radar signals in the secondary radar circuit.

Title: Improvements in or relating to exothermic mixtures
Inventor: ATTERTON DAVID VALENTINE
IPC: F24V30/00
Filed: 1954-10-22
Abstract: An exothermic mixture comprises aluminium, an amount of oxidizing agent well below that needed to completely oxidize the aluminium, 1-10 per cent by weight of a fluoride to facilitate burning of the aluminium and lowering the temperature at which reaction starts, and a small quantity of alkali aluminate sufficient when moistened to set up a reaction with the free aluminium in the mixture.  When the mixture is moulded with water into a sleeve or other shape, sufficient heat is generated to dry off the mixture and render the sleeve &c. self-drying.  The alkali aluminate may be sodium aluminate in an amount between 0.5 and 1.5 per cent by weight of the mixture, and it may be added to the mixture before moistening or to the water used for moulding.  The time delay before the self-drying action commences may be increased by the addition of small quantities of an acidic material such as boric acid, or according to the Provisional Specification, of base metals e.g. up to 5 per cent magnesium powder, with or without 0.01-0.25 per cent of salts of noble metals, e.g. copper sulphate.
