The arms 11, 12, 13 may be adjusted by hand in accordance with information telephoned from the sub-stations, and with the aid of the protractors shown, or may be moved electrically in synchronism with the azimuth movement of the telescopes at the sub-stations. The arms 11, 12, 13 and their protractors may be slidably mounted on rails 14, 15, 16 which are rotatable about a vertical axis so that the points about which the arms turn may be adjusted when the positions of the sub-stations are altered. Tha frame 5 may carry a graduated sector 17 moving over a graduated arc 18, and a pivoted arm 19 adjustable by hand, to enable a gun to be sighted so that the target may be hit at a predetermined point in its path.
Patent GB-603074-A (GB)
Title: A process of manufacturing nutrient materials in the form of flakes
IPC: A23L19/15
Filed: 1941-09-06
Abstract: A food to be eaten with water, skim milk or hot milk is made by mixing potato, tapioca or sago starch, 5-50 per cent. of milk protein and not more than 100 per cent. of water, the proportions being calculated on the dry weight of the final product, heating the mixture on a rotary drum to 100-170 DEG C. and there pressing to a thin layer, which is dried simultaneously or immediately thereafter, and comminuting the dry film to coarse flakes.  The milk protein may be casein but is preferably skim milk powder. The water may be added wholly or in part as skim milk.  Addition to the mixture of a calcium compound, e.g. calcium monophosphate, lactate or chloride, and adjustment of the pH of the mixture to 5-6.5, e.g. by the addition of phosphoric, hydrochloric or lactic acid or an acid salt, diminish the swelling properties of the final flakes.  Substances having a slight disintegrating action upon starch, e.g. hydrogen peroxide, may be added to the mixture. Vitamins, salt, sugar and flavourings may be added before or after the heating and pressing operations.  The flakes may be rendered brittle and browned by further heating at 120-150 DEG C.  The Specification as open to inspection under Sect. 91 comprises also the employment of starches in addition to potato, tapioca and sago starches mixed with any protein e.g. soya bean protein and gluten, also in the proportion of at least 5 per cent. of the dry starch.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to nuclear reactor fuel elements
Inventor: BLAKE LESLIE REGINALD
IPC: G21C3/17
Filed: 1961-03-28
Abstract: 926,344. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 5, 1962 [March 28, 1961], No. 11413/61. Class 39 (4). A metallically sheathed fuel element for a nuclear reactor comprises at least one fuel segment (e.g. fuel segments 12, 13, 14, 15, as shown) of tubular section slit continuously from one end to the other and in direct contact over its outer periphery with the sheathing 11, the resultant slot 18 of keyhole section being filled with a compressible medium, e.g. hydrogen or helium under several atmospheres pressure. The slot 18 imparts radial electricity to the fuel section in a manner analogous to a slitted ring, whereby the contact pressure of the fuel against the sheathing 11, although increased as expansion of the fuel proceeds, is eased by the elasticity of the fuel. The fuel segments 12, 13, 14, 15 are stacked within the sheathing 11 between opposing dished faces of end plugs 16, 17 having rounded extremities and the end portions of the sheathing 11 are swaged over these rounded extremities as a reinforcement for joins effected by spot-welding between the end plugs and the sheathing. Although the slots 18 are shown as being aligned, they may be disposed in a random angular relationship. An alternative to the slot being straight is to out it helically with a pitch several times the diameter of the segment. If the fuel is uranium metal and the possibility of temperatures in excess of 700 C. at the sheath/fuel interface has to be allowed for, the sheathing may be of composite construction so as to afford a layer of a refractory metal in contact with the fuel. An advantage of this shape of fuel segment is that the temperature at the fuel centre is less than if the section were solid which makes possible the use of the fuel at higher heat ratings.

Abstract: 1476327 Electric resistance heating BOC INTERNATIONAL Ltd 7 March 1975 [14 March 1974] 11479/74 Heading H5H A resistor 6 for use in evaporating liquids consists of a liquid permeable body having recesses 18 in the surface to facilitate escape of vapour generated deep within the body thus reducing entrainment of liquid in the vapour. Resistor 6 is a hollow open ended cylinder of carbon fibres mounted under compression between annular terminals 4, 16. Tube 2 conducts liquid to the interior of resistor 6 via perforations (not shown) within the cylinder. It is connected via collar 8 to a low voltage high current source 10 and via terminal 4 to the resistor. Support 12 interconnects source 10 and terminal 16 and is separated from collar 8 by resilient, biasing insulator 14. The recesses may be blind holes (28, Fig. 5, not shown) or elongate grooves 18. Grooves 18 may be inclined to the axis of the cylinder and may extend to the ends of the cylinder. To suit the liquid being evaporated, they may be broad or narrow, may have a depth from one third to nine tenths of the thickness of the wall of the cylinder and have any desired crosssectional shape. The width of rib left between grooves is approximately the same as the depth of the grooves, and less than twice this depth. Where the resistor is too permeable and liquid passes through too quickly, an inner linning of permeable insulating material may be provided, e.g. of alumina (7, Fig. 2, not shown).

Title: Improvements in rapid acting valves for vacuum brakes
IPC: B60T13/46
Filed: 1932-04-23
Abstract: 397,962. Fluid-pressure brakes. VACUUM BRAKE CO., Ltd. and STEVENS, W. C. I., 3, Old Queen Street, London. April 23, 1932, No. 11711. [Class 103 (i).] A rapid-acting valve for vacuum brakes comprises a diaphragm 4 separating a chamber and connected to the train pipe 10 and a chamber 9 connected to the brake cylinder and a primary valve 18 adapted to effect a local admission of air to the train pipe from the atmospheric inlet 28 and a secondary valve 16 adapted to admit air to the brake cylinder, the valve 18 closing when the valve 16 opens and the valve 16 closing when the pressure in the train pipe and brake cylinder balances. When train pipe pressure increases on brake application the valve 18 is first opened by the hollow stem 20 of the diaphragm and the valve 16 is then opened by the spring 21 and closes against the valve 18 which closes the atmospheric port 26, air being admitted to the brake cylinder through a restricted port 27 only, until brake cylinder and train pipe pressure balance and allow the valve 16 to reclose. These operations take place at each admission of air to the train pipe. The brake cylinder is evacuated through a non-return valve 13. In running conditions the spring 21 is uncompressed.
Patent GB-1003623-A (GB)
IPC: B65H7/06
Filed: 1962-03-27
Abstract: 1,003,623. Gauging apparatus. CHICAGO MACHINERY LABORATORY Inc. Mar. 27, 1962 [April 3,1961], No.11752/62. Heading G1M. [Also in Divisions B4 and B6] In a stapling machine for book signatures SG conveyed towards a stitching mechanism SM along a saddle plate SD over which they are draped so as to straddle the latter, the thickness of one side of the signature groups is gauged at an apertured portion 20N of the saddle plate and the wire fed to the stapling heads arrested in response to a gauging signal corresponding to a non-standard number of pages. As shown best in Fig. 6, the sheets pass between an idle roller 31 and a cam 30 rotating with a driven shaft in synchronism with the feed of the signature groups, so that the high portion 35 is operative in gauging. The idle roller 31 is carried between areas 63 fast with a shaft 61 which is rocked by the cantilever action of the roller 31 if the latter deflects from a detum position due to the passage of a faulty signature group. A long spring-loaded lever 85 rigid with shaft 61 will thus also be deflected into either of the dotted positions and close one or other of a pair of microswitches 94, 95 to energize a solenoid and, by means of a push-rod, pivot clockwise a lever in the stitching mechanism to hold a pivoted feed holder out of contact with the stapling wire used therein. A timing cam 116R (Fig. 6) bearing against a roller 115 on the lever 85 has a dwell 116L and is driven in synchronism with the gauging cam 30. The latter holds the lever 85 in the datum position until the dwell is operative (during the time the cam portion 35 is operative in gauging), the lever 85 then being primed in a floating condition for rocking in either direction. Provision is made for adjusting the separation of the roller s and the position of the cam 30 on shaft 36. U. S. A. Specification 1,252,011 is referred to.
