Title: Improvements in or relating to processes for the preparation of carbon base materials and nuclear reactors including such materials
IPC: G21C5/12
Filed: 1958-01-21
Abstract: Shaped carbon bodies, suitable for use in nuclear reactors as moderators, reflectors or heat carriers, are prepared from graphitic carbon, either by mixing it with a deuterated heavy hydrocarbon material in which the atomic ratio of deuterium to carbon is at least 1.3 to 1 and compressing the mixture, or by compressing the carbon and then impregnating it with the hydrocarbon.  In either case the shaped bodies are then subjected to high energy, i.e. above 500 KeV, radiation in order to convert the deuterated hydrocarbons and carbon into a non-graphite carbon with a small, i.e. 0.5-5% by weight, content of firmly bound deuterium.  The graphitic carbon is prepared at temperatures of 2000 DEG C. to 2500 DEG C.  Suitable radiation includes a -, b -, and g -rays, and fast electrons, protons or neutrons.  For example, the shaped pieces may be introduced into a nuclear reactor.  The exposure to radiation is preferably effected between 100 DEG C. and 400 DEG C., especially below 300C DEG ., and the final product preferably has a deuterium:carbon atomic ratio of at least 1:5.  The deuterated heavy hydrocarbon material may be prepared by the deuteration of heavy naphthenic or paraffinic hydrocarbon material, i.e. material whose vapour pressure is at least 20% below the operating pressure at the temperature at which the high energy radiation treatment is performed.  Preferably the material has a melting point of at least 50 DEG C.  Suitable materials include naphthenic hydrocarbons having two or more rings, for example polynaphthenes derived from polystyrene or from anthracene, phenanthrene and acenaphthene; napthenic oil fractions; branched or unbranched alkanes having 10 or more carbon atoms, including mixtures, for example paraffin wax and heavy mineral oil fractions; and alkene polymers such as polythene.  The deuteration may be performed by the method of Specification 798,030. Specification 798,029 also is referred to.
Patent GB-1462971-A (GB)
Title: Heat exchanger
IPC: F28F21/06
Filed: 1974-01-16
Abstract: 1462971 Making heat exchangers; coiling and bending ATOMENERGI AB 16 Jan 1974 [16 Jan 1973 24 Aug 1973] 02062/74 Headings B3A and B3E [Also in Division F4]  A convector space heater comprises a single tube 1 wound into a continuous non-spiral coil of generally flattened overall configuration and having a medial reference plane, the coil comprising a series of loops having runs connected by end portions with some of the runs on at least one side of the reference plane being spaced closer thereto than others on that same side. As shown the coil is supported at its centre and near the end portions by spacer elements 2 each of which is made up of three pivotable and suitably recessed co-operating sections 3, 4. Pivoting of the sections 3, 4 so that they lie in the same plane (see Figs. 3 and 5) displaces the runs of the tube coil so that some are spaced closer to the medial reference plane. The tube may be made of metal, crosslinked polyethylene or reinforced rubber. The coil may be produced by winding a tube around various types of spaced apart upright formers (see Figs. 8-10) which are later removed after spacers (19, Fig. 12) have been inserted (see Figs. 11-15). Each former may comprise a stack of separate circular or semicircular discs held together axially by a central nut and bolt (see Fig. 8); the adjacent discs may be displaced relative to one another (see Figs. 9 and 10). The members serving to space apart and support adjacent turns of the coil may be in the form of rods (21, Fig. 18) or grooved bars (23, Fig. 17) between which the tube turns are clamped; clamping together serves to compress the coil and hence reduce its thickness (see Fig. 18). In an alternative construction (not shown) the bend portions of the coil are coaxial and are wound on uprights that act both as formers and supports. The uprights can be metal tubes with ribbed sleeves to locate the tube turns. Preferably the uprights are mounted in a wooden frame and are spring urged away from each other to keep the coil taut.

Title: Improvements in clamping means in heel-attaching and heel-building machines
IPC: A43D83/00
Filed: 1948-01-26
Abstract: 640,548. Heel - attaching machines. POCKIN, H. W., and BROMLEY, J. H. Jan. 26, 1948, No. 2264. [Class 17(i)] In a heel attaching or building machine, hydraulically operated clamping means are provided by which the heel and shoe are clamped with an adjustable pressure. The hydraulic fluid is sealed in the pressureapplying position while the attaching pins are driven against the pressure of the sealed hydraulic fluid only. A heel clamp F vertically above a heel rest R is attached to a cylinder D in which is a fixed piston E. Fluid pressure is supplied through a control valve C from a pump B to an axial passage in the piston E to move the cylinder D and clamp F towards the rest R. The control valve C operated by a treadle K through a rod J then seals the fluid under pressure in the cylinder D while the pins are driven, after which the control valve is returned to cut off pressure from the cylinder D so that the latter can be returned by a spring Y up to a stop T. A reservoir A in the return from the valve C to the pump B keeps the system primed. The cylinder D has two bores of different area so that if a high heel is clamped as in Fig. 6 the fluid enters the space SP to give a light pressure while if the clamp F is lowered further for a shorter heel the fluid enters the space ST to give greater pressure. The two bores can be connected by small bores to prevent air locks and oneway ball valves for relieving the pressure from ST may be provided as shown in Fig. 6. In operation, a shoe and heel are positioned on the rest R and the treadle K depressed which through a latch L and rod J operates the valve C to admit fluid to the cylinder D to clamp the heel. Further depression operates the valve C to seal the fluid in the cylinder D and at the same time through a collar P and a lever Q engages a single cycle clutch to operate a driving plunger I by an eccentric N. A cam surface S then engages a lever M which withdraws the latch L to allow 'the rod J to be returned by the action of a spring W and the lever Q to disengage the clutch. The parts thus return to their initial position ready for the next operation. Specification 544,315 is referred to.
