Title: Improvements in or relating to nuclear reactors
IPC: G21C3/28
Filed: 1960-04-29
Abstract: 882,598. Fuel elements. HUET, A. April 29, 1960 [May 13, 1959], No. 15235/60. Class 39(4) Fuel elements are formed with axial channels and the helical transverse channels, as shown at c so that coolant flowing in the channels c enters the axial channel tangentially; with H 2 O or D 2 O as coolant, this arrangement causes separation of steam in the axial channel, which steam is then superheated. The direction, number and cross-section of the transverse channels may vary along the element; the rod and the axial channel may be cylindrical or frustro-conical. The element may be of metal, oxides, or oxides mixed with a ceramic material, and may have a sheath with surface undulations.

Abstract: 712,560. Wire fabrics. EASTERN ROTORCRAFT CORPORATION. June 18, 1952 [June 19, 1951 ; Jan. 14, 1952], No. 15341/52. Class 45. [Also in Group VIII] A net device comprises a plurality of flexible cable runs 10 which are generally parallel when the net is folded and extend in zig-zag fashion when the net is open, each interior run being attached to the adjacent run on one side at spaced points and being similarly attached to the adjacent run on the other side at alternately spaced points to form a series of parallelograms when the net is open, a plurality of load attachment terminals 13. 14 being located at the ends of the cable runs. The cable runs 10 are connected together to lie in the same plane by clips 11 which are crimped or swaged as indicated at 12. The load attachment terminals consist of rings 13 and hooks 14 attached to the sides of the net. Rings may also be inserted at intervals in the net to provide holding down points if the whole area of the net is not required. By connecting the cable runs so that they are in the same plane the net can lie collapsed so that the runs are substantially parallel to each other so that the net can be rolled up.

Abstract: 954,795. Transformers. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 2, 1960 [May 5, 1959], No. 15349/60. Heading H1T. The single layer turns 1 forming transformer or other coils, which may be insulated by interwound flat strip material 2, are introduced into a mould and embedded under pressure in a mixture of an unsaturated thermo-hardenable polyester resin and glass fibres which is then hardened to form an insulating envelope. An injection moulding process may be used and supporting beams in the mould may form part of the finished structure. The envelope formed may be 1 to 2 mms. thick at 4 being thickened up to 1 cm. at 3 so that when the coils are disposed on a core the thickened parts 3 act as spacing members and provide spaces between the coils permitting air circulation. Fig. 4 shows an arrangement with two separated layers of turns for a transformer with an air space between them for cooling purposes. An example of the composition of a suitable paste is given.

Title: Improvements relating to gas cut-off valves
Filed: 1936-06-02
Abstract: 475,664. Thermally-actuated valves. BRITISH BRASS FITTINGS, Ltd., and SPERRYN, G. N. June 2, 1936, No. 15357. [Class 135] [Also in Group XIII] A thermally-actuated safety cut-off valve for gas burners of the kind initially opened by hand, has a heat responsive member f to which is secured a pillar i carrying a heat-catching disc or plate j, the plane of which is perpendicular to the pillar. The plate is rotatable to change the portion of its periphery exposed to the burner flame or flames. The plate may be of polygonal form and may rotate on the pillar i or with it. In the former case, the plate is secured to the pillar by a nut and spring washer. In either case, however, the connection may be made by riveting over the ends of the pillar. The riveting is performed so that the plate is readily adjusted but maintained in adjusted position by friction. The pillar i may be screwed into the member f which is shown as a bi-metallic strip. If more than one heating conducting plate j is used, a distance piece is inserted between them. As shown, the valve c is opened against a spring by a hand plunger e operating on its stem d. A burner with five nozzles such as h is also shown.

Abstract: 476,257. Gauging toothed gears. PRETTY, H. J. June 6, 1936, No. 15882. [Class 106 (ii)] Relates to apparatus in which two meshing gears are mounted to revolve respectively with rotary discs of the same ratio which have their peripheries flexibly connected to moving members which move synchronously while there is no variation and at different speeds while there is variation, and consists in forming the members as parallel moving slides carrying cooperating parts of an indicator. A base block 11 has a transverse slot 12 in which are adjustably mounted upright pins upon which are sleeves 14, 14 fast with rotary discs 1.5, 15. The gear pair to be tested 16 are mounted above the discs and secured by nuts 17. The gear ratio is the same as that of the discs 15. Either of the gears may be a master. To the periphery of each disc is secured a flexible steel strip 18, the other end of which is secured to a slide 19. The slides 19 are mounted on balls 20 working in grooves 21. The strips 18 are kept taut by weights 22 flexibly connected to the slides 19. A stationary scale 25 is secured to one slide 19 and co-operates with a long pointer 26 pivoted at 27 to a bracket 28 fast on the slide. Engaging the pointer 26 near its pivot is the lever 29 fulcrumed in a spring blade 30 fast on the slide and pivotally connected at 31 to a block 32 fast on the other slide. As the gears are rotated if there is no variation in the angular velocities of the gears, the two slides will travel equally and the reading remain at zero. Any variation between the gears will cause one slide to move relatively to the other when the indicator will give a reading.

Title: Improved method of drying materials
IPC: F26B1/00
Filed: 1938-05-28
Abstract: Materials which solidify and harden during the drying operation, such as lime sludge from the sulphate cellulose process, are dried by first drying the material in a thin layer until it has hardened and substantially lost its adhesive power, and then crushing the hardened material into small pieces or particles which are finally dried in a thicker layer than the original one, preferably by blowing air therethrough.  The process is carried out in an apparatus having two chambers, in the first of which the wet material is dried in a thin layer on a conveyer.  The material is then crushed and introduced into the second chamber in which it is laid in baskets, on nets or on wire-net carriers or conveyers through which hot air is passed.

Abstract: 1421696 Measuring peak voltages TOKYO SHIBAURA ELECTRIC CO Ltd 11 April 1974 [14 April 1973] 16161/74 Heading G1U [Also in Division H3]  The output of an analogue-to-digital converter 1 is normalized so that the highest encoded value it derives from a time-varying analogue input signal 5 is a predetermined value. For an initial period whenever the output of register 7 is greater than that of register 11 it is transferred to register 11 so that at the end of the initial period the register 11 holds the highest value that has occured. Switch 10a is then opened and switch 10b closed. The complement of the signal in register 11 is then converted at 16 to analogue, adjusted at 17, and subtracted at 4 from the reference voltage 3 used by the converter 1 to effect the desired normalization. The input 5 may be an electrocardiac waveform, the output may be converted at 14 back into (normalized) analogue form.
