Title: Improvements relating to cradles used on buildings and the control and installation thereof
Inventor: COOLE PETER JAMES
IPC: E04G3/22
Filed: 1964-10-20
Abstract: 1,064,529. Taking up slack in electric cables. CRADLE RUNWAYS Ltd. Oct. 20, 1965 [Oct. 20, 1964; May 11, 1965; May 12, 1965], Nos. 42807/64, 19883/65 and 20069/65. Heading B8B. [Also in Divisions E1 and E2] A workmen's cradle 8 is suspended from a trolley 3 at the top of a building by cables 6, 7 on which are a number of guiding rings carrying plugs 16, 17 which can be engaged with any two adjacent sockets of one of a series of horizontal rows of sockets 12, 13, &c., on the face of the building, to restrict the length of cable on which the cradle can swing. The plugs 16, 17 operate microswitches and the electrically driven winding drum in the trolley has limit switches, so that the cradle can only be wound up and down for the distance between the trolley 3 and the sockets 12 or between any two adjacent horizontal rows of sockets according to which row of sockets are engaged by the plugs. The traversing of the trolley and winding of the cradle are controlled by push buttons by means of an electric cable between the trolley and the cradle. The trolley 3 is traversed along a track 2 when the cradle is at the top and when a wander plug 9 is disengaged which cuts out the winding motor. When the plug 9 is engaged with one of a series of sockets 11 the traversing motor is cut out and the winding motor circuits are prepared for operation. In a modification each set of two plugs and two guiding rings are mounted on a bar, the bars being carried in brackets on the cradle, Fig. 4 (not shown). The cable from a winding drum 54, Fig. 5, passes over a pulley 53 mounted to be moved along shafts 56, 57, shaft 56 being screw threaded so as to move the pulley 53 along the shafts in order to keep the cable between the pulley and drum at right angles to the axis of the drum. The screwthreaded shaft 56 is turned by a wheel 58 having rollers 59 adapted to be engaged by projections 60 on the drum. A cable for supplying electricity to the cradle is mounted on a winding drum, Fig. 8 (not shown), having a traversing pulley driven by mechanism similar to the drum 54 and driven through a slipping clutch which slips when the cradle is moving and thus keeps the cable taut. A plug 16 or 17 comprises a main tube having a split spring collar at one end. A second outer tube can be slid on the vacuum tube so that its conical end engages a conical recess in the collar to expand the collar and force a flange thereon into a recess in the socket and thus lock the plug in the socket, Figs. 2, 3 (not shown).

Title: Improvements in fuel elements for nuclear reactors
IPC: G21C3/36
Filed: 1965-10-12
Abstract: 1,070,677. Fuel elements. KERNFORSCHUNGSANLAGE JULICH DES LANDES NORDRHEIN-WESTFALEN C. V. JULICH. Oct. 12, 1965 [Oct. 22, 1964; Feb. 23, 1965], No. 43320/65. Heading G6C. A fuel element for use with water-cooled or metal-cooled nuclear reactors comprises an incoherent filling of particles of the carbides, oxides or nitrides of fissile materials coated with carbon or carbides, or with beryllium oxide, contained in a can of a corrosionresistant metallic material, e.g. a zirconium alloy or corrosion-resistant steel, closed in a vacuum-tight manner. Fillers such as beryllium oxide in the form of a powder or beads and having good thermal conductivity may be mixed with the fuel particles. The fuel particles may be arranged in the annular gap of a fuel can of hollow cylindrical form, the coolant flowing over both the inside and the outside walls of the can which are preferably kept at different temperatures by having the fuel particles, mixed with a filler in powder or bead form, non- homogeneously distributed over the crosssection of the fuel element. It is thus possible to raise the temperature of the coolant in two stages as, e.g. in a water-cooled superheater reactor. This non-homogeneous distribution of the fuel/filler mixture can be obtained by the insertion of very thin partitions in the annular gap or by utilizing the demixing in accordance with the differential mass of the particles which occurs on the mixture sliding down an oblique plane. Furthermore, it is possible for the mixture of fuel particles and filler to be so charged throughout the length of the fuel element that a particularly desirable distribution of the neutron flux density is obtained. A further improvement consists in filling the spaces between the solid constituents by helium or other inert gas at a pressure equal to that of the coolant flowing over the element. The fuel particles and the optional filler may be introduced into the can and packed as dense as possible by shaking or vibration.

Abstract: 1287115 Counting sheets KOMBINAT ROBOTRON VEB 3 Sept 1969 43561/69 Heading G4D Flat sheets 3 (i.e. punched cards) are moved serially along a conveyer 2, and are counted by photo-electric means which sense when two sheets are placed one above the other and cause rejection or a halt in the conveyer. Light from a source 8 impinges on the lateral edges of the sheets 3 and causes a pulse to be received at photo-electric elements 13, 14 by way of a rotating glass prism 15. If there are two sheets, two pulses are received. The resulting electrical pulses are fed to an electronic device (Fig. 3, not shown) which, if there are two pulses received in quick succession i.e. two coincident sheets sensed, activates a rejection or halt means. The prism 15 may be dispensed with and the elements 13, 14 moved instead. In another embodiment (Fig. 4, not shown) the prism 15 is dispensed with and one or more matrices of photo-electric elements are used.

Title: Electrophotographic and like recording processes
IPC: G03G5/147
Filed: 1962-11-26
Abstract: 1,033,419. Liquid development of electrostatic images. GEVAERT PHOTO-PRODUCTEN N.V. Nov. 26, 1962 [Nov. 27, 1961], No. 44694/62. Addition to 1,020, 503. Heading G2H. The process of the parent Specification is modi - fied in that the electrostatic charge image is formed by traversal through an electric field of a photo-conductive material having a hydrophobic surface layer which is subjected to a simultaneous or prior exposure to a radiation pattern. If a photo-conductive material having rectifying properties is employed an A.C. field may be used, typically of frequency 50 to 5000 c/s. Non-sinusoidal A.C. or combined A.C. and D C. may be used for the field. The photo-conductive materials may be as in the parent Specification or as in Specifications 1,020,504 and 1,020,506. If the backing of the material is positive to the photo-conductive layer the developed image is a negative of the original while if the backing is made negative a positive copy is obtained. Development to give a visible image may be effected by passing the exposed sheet between rollers across which the field is applied, one of which is wetted with the developer liquid which may be as in the parent Specification with the optional addition of a conducting acid, salt, or base. The rollers may be smooth or the applicator roller may be grooved providing that contact with the sheet to be developed is sufficient to cause a bead of developer to be formed between roller and sheet. Alternatively developer may be applied to an intermediate roller engaging a hollow transparent drum having a photo-conductive outer surface surrounding a light source and document to be copied placed on its inner surface so that simultaneous exposure and development occur. The developed image may be transferred to a paper sheet brought into contact with the outer surface of the drum (Fig 5 not shown). In a modification (Fig. 6 not shown), the intermediate roller is dispensed with.
