Title: Improvements in or relating to prepayment meter mechanism
IPC: G07F15/00
Filed: 1933-01-12
Abstract: 410,559. Prepayment mechanism for meters. GRASEBY, R. C., Venner Works, Kingston By-Pass Road, New Malden, Surrey. Jan. 12, 1933, No. 1071. [Class 27.] Mechanism for preparing basic charges.-Relates to prepayment meter mechanism of the kind described in Specification 397,651 in which the commodity control is actuated by quantity mechanism set forward by prepayment and returned to zero by driving means, for example, a spring wound by prepayment, under the action of a consumption meter and a time motor, the connection between the meter and the quantity mechanism comprising a control barrel driven by the meter and having flats thereon to allow rotation of a flier which is driven by the driving means. According to the invention, the flier is allowed to rotate either by rotation of the barrel on its own axis, whereby the flier is released or by bodily translational movement through space of the barrel or by both simultaneously, the meter and the time motor being each connected to the barrel, the one to rotate it on its own axis and the other to give it or permit it to have bodily translational movement, and each motor operating independently of the other. As applied to an electricity meter, one sun-wheel 2 of an epicyclic quantity mechanism is rotated by prepayment thereby setting forward a planet-wheel 3 connected to a gapped switch control disc 5, similar to that described in Specification 1363/14, [Class 27], and winding up a return driving spring 4. The other sunwheel 6 is fixed to the spindle 7 of a flier having arms 8, 9 which pass through grooves 11 in a barrel 10 when this is rotated. The barrel 10 is rotatably mounted in the end plates 14, 15 of a cage 16 which has a gear wheel 20 connected through gearing 21 to a time motor 22. The barrel carries a wheel 17 meshing with a wheel 18 on a spindle 19 in alignment with the spindle 7 and rotatable in the end plate 15, this spindle 19 being connected by gearing 23 to the consumption meter 24. The meter 24 rotates the barrel 10 on its own axis to release the flier, the spindle 7 of which is rotatable in the end plate 14, and allow the spring 4 to return the disc 5 towards zero position. The time motor rotates the cage 16 bodily and the flier driven by the spring 4 follows the barrel 10 round. At the same time, the barrel being geared to the spindle 19 rotates on its axis and allows the flier to move still further. The time motor allows the return of the disc 5 in accordance with the standing charge to be collected. The cage 16 may be rotated by the time motor in a direction to cause the flier to wind up the spring 4, the rotation of the barrel 10 on its axis, caused by its being geared to the spindle 19, releasing the flier to allow its rotation in the opposite direction.

Title: Improvements relating to graphite structures in nuclear reactors
Inventor: BRIDGE HARRY
IPC: G21C1/12
Filed: 1962-01-12
Abstract: 1,021,452. Moderator structures. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 2, 1963 [Jan. 12, 1962; Feb. 7, 1962], Nos. 1212/62 and 4806/62. Heading G6C.  The graphite moderator structure of a nuclear reactor comprises graphite having different thermal expansion coefficients in regions of different normal operating temperature with the objective of dimensionally stabilizing the graphite under neutron irradiation. The coefficient of thermal expansion in at least one direction in each region is selected by (a) correlating the temperature of normal operation of that region with the irradiation temperature required to produce the same net damaging effect on graphite under the irradiation conditions of chosen available graphite irradiation data; (b) estimating for such irradiation temperature the bulk dimensional changes indicated by said data; and (c) using these dimensional changes to determine the requisite coefficient of thermal expansion. The regions may be layers of uniform thickness but, in general, the structure is divided into regions each defined by isotherms corresponding to the limits of preselected temperature ranges covering the full compass of the temperature distribution. In order that dimensional stability may prevail in all directions, the graphite selected should have a random crystal orientation of high crystallographic perfection and be substantially isotropic at least to the extent of the thermal expansion properties.
