Filed: 1960-04-13
Abstract: 938,230. Foundry plant. BADISCHE MASCHINENFABRIK A.G. April 13, 1960 [Feb. 10, 1960], No. 13154/60. Class 83 (1). In an automatic moulding installation empty boxes 5, 6 are lifted from a conveyer 3 to an upper or lower box moulding station 7 by a lifting appliance 9 movable on a transverse beam 1, and comprising a sand measuring and filling container 12, a filling frame 36 and a profile strickler 40, and moulded boxes are moved from the moulding station to a parallel conveyer 4 by a lifting appliance 10 which is driven on the same transverse girder 1 and comprises a presser head 31 and a box turning device for drags 6 or a box clamping device for copes 5. The control arrangement is such that the start of each working stage is separately controlled in dependence on the orderly finishing of the preceding operative stages for both the empty box appliance and the filled box appliance independently of one another, which appliances are themselves only jointly or successively transversely driven in the same direction. The lifting appliances 9, 10 are moved transversely by the cylinders 2. The boxes are positioned on the conveyer 3 by' plungers 13, and the box-gripping fingers 17, Fig. 4, engage under the box pins 18 and are movable vertically by cylinders 15 and horizontally by cylinders 16. The grippers are positioned by pins 26 and elements 21 engage in slots 22 in the box pins 18. On the lifting appliance 10 associated with the apparatus for moulding drags the grippers are rotatable through 180 degrees by a crank 23, Fig. 4, operated by a piston 24. The press cylinder 30 has a counterpressure piston 32. Blowing nozzles 35 on the appliance 9 clean the moulding plate 8 during movement of the appliance to the left. The profile strickler 40 follows a cam path 41 during strickling, e.g. to hollow out the surface towards the middle of the moulding box so that a greater consolidation of sand will take place at the moulding box edges.

Title: Improvements in or relating to cable sheaths
IPC: H01B13/22
Filed: 1956-05-01
Abstract: 864,513. Automatic temperature-control systems. JOHNSON & PHILLIPS Ltd., and HARRIS, D. J. Aug. 1, 1957 [May 1, 1956], No. 13369/56. Class 38 (4). [Also in Group XXII] A method of heating a metallic cable sheath prior to reducing it on to a cable core by drawing both through a die 4, Fig. 2, includes a control system which utilizes the change of resistance on heating of the sheath to operate a relay and reduce the heating current. The sheath 1 is heated by alternating current from a secondary coil 10 of a loading transformer, the dies 3, 4 acting as electrodes. When the temperature of the sheath becomes excessive its resistance between an electrode 14 and the die 4 increases so that the potential drop across a primary coil 13 of a voltage transformer also increases while the drop across a transformer primary coil 12, in parallel with a resistance 13 in the heating circuit, decreases. The change in distribution of potential drop causes the energization of a transformer secondary coil 15 to cancel that of a coil 16 which is in opposition and was previously the greater, so that the input to an amplifier 17 falls and a relay 19 is operated by coil 18. The D.C. saturation winding 20 is thereby opencircuited causing a decrease in the energization of the loading transformer primary winding and a reduction of the heating current. On a falling temperature the relay switch closes to increase the energization and the heating current. A modified control system, Fig. 3, introduces a third electrode 25 and a loading transformer having two secondary windings 26, 28 so related that the voltage across the dies 3 and 4 is ten times that across the dies 25 and 3. Current transformers 29, 31 maintain a potential drop across resistances 30 and 32. When the temperature of the sheath between the dies 3 and 4 becomes excessive the resistance increases causing the potential drop across the resistance 32 to decrease, that across the resistance 30 remaining constant since the voltage in the circuit of winding 28 is small. The input of an amplifier 33 is thereby decreased and a saturation winding open-circuited as before. Specifications 627,793 and 627,815 are referred to.

Title: Improvements in or relating to fuel element assembly for nuclear reactors
IPC: G21C3/16
Filed: 1960-04-14
Abstract: 913,658. Fuel elements. BABCOCK & WILCOX CO. April 14, 1960 [April 17, 1959], No. 13372/60. Class 39 (4). In a fuel element for a reactor in which pressurized water acts as both a coolant and moderator, fuel pins are spaced apart within a chamber and the outer layers of pins, adjacent the chamber inside surface, have a lower fissionable content than the inner pins, to avoid a higher rate of heat generation at the surface than in the element interior. In addition, when the pins are in square cross-section groups, the four corner pins have a further reduced fissionable content such that a reduction of coolant flow past the corner pins due to diagonal blowing, does not cause overheating of the comers. Each pin contains both fissionable and fertile material, thorium. As shown, the assembly 10 comprises a flow chamber 12 with coolant inlet and outlet, 14 and 16 respectively, and contains fuel pins 18. Each pin is formed of fuel cylinders 24 within tube 22 which is sealed by cap 28 with insulating pellet 26 between the cap and fuel. Spacing members 30, 32 are brazed to the fuel pins and permit the flow of coolant with a small pressure drop. The outer layer pins are connected by spacers 32 which project outwards and maintain a space between the pins and wall 11. The complete pin assembly, 20, is positioned within 12 by the shoulder 34 which engages the outer fuel pins 18A. Specification 913,653 is referred to.

Title: Improved process and apparatus for the manufacture of aluminium lubricating greases
Filed: 1943-08-23
Abstract: <PICT:0584370/III/1> In the manufacture of aluminium grease, the hot grease of temperature 200 - 350 DEG F. usually 280-300 DEG F. is finished in two stages, firstly the grease is rapidly cooled in a cooling zone to the transition temperature or nearly thereto, and secondly the cooled grease is transferred to a transition zone comprising a number of vertical towers where it is kept at constant transition temperature and at rest for a period of time until the transition from a stringy or rubbery form to an unctuous gel is effected. The transition temperature varies from 90-180 DEG F. depending on the grease composition; thus 140-160 DEG F. for an aluminium stearate grease, 100-140 DEG F. for a 80-95 per cent. stearate and 20-5 per cent. aluminium naphthenate grease, and 90-120 DEG F. for a 80-95 per cent stearate and 20-5 per cent. naphthenic acid grease.  The greases may be made from the usual aluminium soaps including such soaps of synthetic fatty acids made by the oxidation of paraffin wax.  The cooler may comprise ordinary cooled pipe coils, a jacketed kettle, or preferably a jacketed helical conveyer type chiller.  The transition towers are well insulated or jacketed, and are preferably of a height of at least twice, but not more than five, times the diameter.  In the plant shown, the hot grease is fed through the cooler 2 and then into one of the transition towers 4. The latter are provided with floating pistons 5 which are raised by the incoming grease compositions.  After the transition is completed, the towers are emptied by supplying compressed air from line 6, the grease passing through line 7, through a filter 8, into the filling equipment.
