Title: Reactor control
IPC: G21C7/08
Filed: 1946-05-10
Abstract: 817,755. Nuclear reactors. GOETT, J. J. May 10, 1946 [May 22, 1945], No. 14251/46. Drawings to Specification. Class 39(4). In a nuclear reactor abnormal rises in the value or rate of rise of neutron density are prevented. Spheres of neutron absorbing material are projected at high velocity, into a horizontal channel in the reactor core in response to signals from a neutron density measuring instrument mounted near the reactor reflector. The spheres of cadmium, boron or silver are stored in a container which is mounted adjacent to the reactor outer surface and which is maintained spinning about a horizontal axis. An aperture associated with the container and the horizontal channel, is opened in response to the output from the measuring device and the spheres are projected, in a stream, into the channel by reason of their stored kinetic energy. The impact of the spheres is abosrbed by an air cushion formed inside the channel. Should the electrical supply into the motor spinning the container fail, a flywheel mounted on the container spindle maintains rotation. The reactor consists of a carbon moderator, with water cooled, uranium, fuel rods and cadmium control rods mounted in vertical channels. The reactor upper surface is shielded by a mass of water and lead shot. The fuel rods are aluminium sheathed. Specification 817,751 is referred to.

Title: Bags
IPC: B65D30/24
Filed: 1978-04-12
Abstract: The bag (1) comprises two layers of a plastic film lying on top of one another. After cutting-off of an appropriate length of a tubular structure one open edge is transversely closed with a weld line (2). The opposite end of the bag (1) is cut in such a way that an outwardly projecting, trapezoidal piece (4) is formed. This piece (4) is preferably asymmetrical because it has been shown in practice that this shape is more comfortable to use. The two layers are then welded to one another along two lines representing the continuation of the trapezoidal sides and extending inwards from the edge. The weld lines are designated by the numeral (3). The two angles formed on either side of the trapezoidal sides are blunt angles and are designated by the letters  alpha  and ss. As can be seen, the angle ss is larger than the angle  alpha . Experience has shown that the full bag can be laid aside without liquid flowing out. <IMAGE>

Title: Topping up devices
Inventor: BUSHROD CHARLES JAMES
IPC: H01M50/618
Filed: 1964-04-09
Abstract: 1,099,741. Battery topping up device. ELECTRIC POWER STORAGE Ltd. April 8, 1965 [April 9, 1964], No. 14766/64. Heading H1B. In a topping-up device for a battery of the type having a filling tube 35 for supplying liquid to the battery container and a vent tube 36 which terminates inside the container at the level of liquid it is desired to provide, a liquid trap 37, 38 is provided for the filling tube so that air cannot escape through it but is trapped in the upper part of the cell and so prevents the further entry of liquid after the bottom of the vent tube has been reached. As shown, the liquid trap is formed in a chamber 30 and comprises a cap 37 and depending skirt 38 secured to the vent tube 36. A baffle 41 surrounding the top of the vent tube 36 provides an air lock which prevents liquid entering the top of the vent tube. In filling a plurality of cells liquid is supplied through inlet 16 of a first cell to chamber 30 and then over the top of filling tube 35 into the cell. Air is displaced from the cell via vent tube 36 and out through outlet 17. When the bottom of the vent tube is covered with liquid, the liquid can no longer enter the filling tube 35 and thus follows a tortuous path, provided by the baffle 41, to the outlet 17 of the cell. The other cells are then filled in like manner in succession. The topping-up device may have a removable plug in its top to enable a hydrometer syringe to be inserted into the cell through the vent tube. In Fig. 4 (not shown), the liquid trap is provided at the lower end of the filling tube. The liquid trap may be provided by an inverted J-shaped filling tube whose upper end opens into a supply chamber. Alternatively, the filling tube may be J-shaped with its upper end connected to the chamber. The cells may be separately vented, vented through a common manifold or, as shown, vented through the interconnecting passage through which liquid is supplied to the successive cells. The topping-up device is applicable to a battery wherein the filling tubes are in the bottom of a common channel into which liquid may be poured. The ends of the vent tubes may be formed as interchangeable bells 42 of different sizes to allow different liquid levels to be attained.
