The means to interengage the stud in the socket may comprise an annular shoulder 33a which may be on a rib 33 facing the flange 29 on the stud portion 16 and a recess 22 in the wall of the bore of the socket portion 15. Alternatively the recess may be in the form of slots in the wall of the socket to receive the annular rib (Fig. 7, not shown). In a further embodiment (Figs. 9, 10 and 11, not shown) the stud is formed with a recess and the socket portion is formed with a projection and also the abutments in the form of resilient lugs dispersed with and the flange, such as 19, forms the abutment. In this case the recess may be annular and the projection may be an annular rib or the stud may be generally cylindrical and have a circumferential recess and the socket portion formed with a circumferential rib on the wall of the bore, the periphery of the rib being generally oval and adapted to deform as the stud is forced into the bore and snap engaged into the recess. In a further embodiment (Fig. 13 to 15, not shown) the stud of the stud portion is provided with a series of annular serrations or tongues which engage the recess of the bore of the socket or alternatively the bore in the socket may be in the form of a series of serrations or tongues which engage the shoulder of the stud or alternatively the stud and bore may both have serrations or tongues which interengage each other.

Light from a source 3 may pass through the grating or be reflected by the grating (Figs. 3, 4, not shown). Detectors 9, 10, 11 are positioned respectively to detect the zero order 6, the first order 7, and the second order 8 of diffraction. The detectors may feed threshold units 14, 15, 16 coupled to an AND gate 19 via inverter 17, directly and via inverter 18 respectively so that for an authentic card the zero and second orders must be less than the threshold and the first order must be above the threshold. Alternatively the detectors may feed comparators 21, 22 coupled to AND gate 24 via threshold circuits 23, 25 arranged so that the ratios of the energies of the diffraction orders must lie within predetermined limits. The grating may be produced by etching using a photoresist coating to define the grating lines.

Title: Improvements in up-draught gas producers with particular relation to the use of woodfuel therein
IPC: C10J3/00
Filed: 1936-11-30
Abstract: 480,392. Gas - producers. TELFORD, W. M. Nov. 30, 1936, No. 32763. Convention date, Dec. 3, 1935. [Class 55 (i)] In a gas-producer provided with a central downwardly depending gas offtake pipe 9, tar and heavy hydrocarbons preliminarily distilled from the fuel, particularly wood, are converted into permanent gas by positioning the inlet end of the offtake pipe within the zone of incandescent fuel, the conversion being facilitated by fore-shortening the cooling jacket 12 thereof through which steam from a boiler 11 circulates before its admission to the combustion chamber 1, mixed with air, through a pipe 7, Fig. 6, tangentially arranged thereto. The pipe 7 enters into the space between the unlined walls of the combustion chamber and an external casing 4, the gasefying medium circulating therethrough at a high velocity before entering the combustion chamber through a grate 2 which is smaller in cross-section so as to form a barrel-shaped mass of incandescent fuel. The diameter of the offtake pipe 9 is specified as one-tenth that of the combustion chamber and its unjacketed end is preferably constructed of heat-resisting steel.

Title: Improvements in metallic moulding powders and processes for their production
IPC: B22F1/17
Filed: 1938-11-11
Abstract: 521,051. Making metal powder. JOHNSON BRONZE CO. Nov. 11, 1938, No. 32897. Convention date, July 18. [Classes 83 (ii) and 83 (iv)] Metallic powders which are cold moulded into metallic articles and then sintered have the smooth surfaces of the particles roughened or given a dendritic form by sintering and are next ground before moulding. The original powder may be formed by grinding or by reduction by heat, such as the heating of an iron carbonyl, and a relatively coarse powder, passing through a 100 or 150 mesh to the inch screen, is preferably mixed with a finer powder, e.g. passing through a 250 mesh screen. The two powders may be of the same or different metals or alloys and the grinding of the coarser powder is performed in an oxidizing atmosphere so that the particles become coated with oxide which is subsequently reduced when the sintering is performed in a reducing atmosphere. In an example, for making bronze bearings, the coarser powder is produced by grinding bronzeturnings &c. under oxidizing conditions and is mixed with a finer copper powder which may also be oxidized or not. The mixture is then heated in a reducing atmosphere at a temperature between 500 and 1,800F., preferably about 1,300F., and then ground ready for moulding. The moulding is preferably performed with the addition of about 5 per cent. of tin. A metal powder may be mixed with a reducible metallic compound before sintering, e.g. oxidized iron and iron oxide or oxidized copper and copper oxide; copper cyanide, copper oxalate &c. may be sintered in a reducing atmosphere. In making moulded articles the metallic powders may be used alone or mixed with other powders.

Title: Nuclear reactor fueling method
IPC: G21C5/18
Filed: 1969-06-30
Abstract: 1,203,570. Breeder reactors. UNITED STATES ATOMIC ENERGY COMMISSION. 30 June, 1969 [8 Aug., 1968], No. 32911/69. Heading G6C. In a large fast reactor, loss of coolant, e.g. sodium, from the central portion of the core produces positive reactivity. This effect, which is a safety hazard, is largely contributed to by any Pu-240 isotope and fission products present in the central core portion. This danger is minimized, according to the invention, by a method of refuelling which includes the step of introducing into the central core portion fuel having less than 8% Pu-240 isotope content and removing the fuel from this core portion before the isotope content exceeds 25%. As shown in Figs. 1, 2 a spherical core has a central zone A surrounded in turn by zones B, C and a breeder blanket. Zone A is fuelled with PuO 2 - UO 2  fuel in which the Pu is "clean", i.e., it contains less than 8% Pu-240 content. The Pu-240 content increases during burnup of the fuel and before this content attains 25% the fuel in zone A is transferred to zone B as partially "dirty". The fuel in zone B is next transferred to zone C where it becomes "dirty", i.e., it contains more than 25% of isotope Pu-240. The "clean" fuel for zone A may be obtained from the breeder blanket which initially contains UO 2 . The fuel from zone C is reprocessed to remove fission products and the partially "dirty" fuel obtained is used in zone B. In another embodiment (Figs. 3, 4, not shown) the core is cylindrical and fuel elements extending right through the core have sections having different fuel compositions depending upon the axial and radial position in the core of the particular section. Thus a fuel element extending through the central zone of the core has its central section extending through the core centre fuelled with PuO 2 -UO 2  in which the Pu-240 content is less than 8%. Sections of the fuel element to either side of the central section contain partially "dirty" Pu and the end sections forming the axial breeder blankets initially contain UO 2 . The fuel elements forming the outer zones of the core have sections filled with Pu which is "dirty" in differing degrees, the degree of "dirtiness" increasing with increase of the distance of that section from the centre of the core.

Abstract: 863,774. Furnace slag pockets. LOHMEYER, E. Sept. 30, 1959 [May 19, 1959], No. 33180/59. Class 51 (2). Cleaning of an open hearth furnace slag pocket is facilitated by air pipes disposed along the floor and opening to the atmosphere outside the slag pocket, whereby cool air drawn into said slag pocket by the furnace draught during operation prevents the slag solidifying into a large mass. In a modification, Fig. 3, porous water pipes 10 are laid along the floor and covered with a layer 15 of lime, magnesium oxide or dolomite. Vertical and horizontal channels 8 and 9 are respectively formed in a layer 7 of the above oxides covering the side walls and floor of the slag pocket. After operation of the furnace water supplied through pipes 10 and sprinkled from above into channels 8 and 9 causes the oxides to form hydroxides with consequent swelling which breaks up the slag mass.
