Title: Roller driving arrangement
IPC: B65G13/071
Filed: 1980-12-03
Abstract: This invention relates to a device for axially locating a driving spool (22) one drive shaft (18) of a line shaft live roller conveyor (10) having rollers (12) driven by elastomeric drive belts (24) extending from corresponding spools (22) on the shaft (18) extending transversely beneath them. There is a relatively loose frictional fit between the spools (22) and the drive shaft (18), and the twist of each drive belt (24) between the spool (22) and the roller (12) results in a tendency for the spools (22) to shift along the drive shaft (18) with the intermittent application of load. The present invention provides a locating device (28) with a C-shaped resilient body (32) with a mouth (34) which may be transversely snapped over the drive shaft (18) to grip the drive shaft (18) to securely retain it in the desired axial position. <IMAGE>

Title: Microwave Oven
IPC: H05B6/80
Filed: 1981-08-24
Abstract: The oven has a shelf 26 for supporting articles to be cooked. The shelf is supported on four posts 28 at its corners and to which are attached for example knife edges 154 resting in V troughs attached to arms 158 pivotally mounted at 162 and acting on a leaf spring 94 terminating in a septum 46 which obturates the light reaching a photocell 42 from a light source 44 to an extent dependent upon the weight of the article on the shelf 26. Alternative embodiments employ variations in the mechanical structures operatively connecting the posts 28 to sensing means which may be mechanical rather than optical. The signal from the photocell 42 is converted to a digital signal indicative of the weight of the article and this signal is one of the input signals to a microprocessor determining the amount of time for cooking the article. The posts 28 are of small cross- section and pass through apertures in the bottom wall 24 of the oven cavity small enough to prevent the escape of microwave energy. <IMAGE>

Title: System for managing the issuance and return of selected articles such as tools, keys and the like
Inventor: HOLLOWELL JUN ROBERT L
IPC: E05B11/00
Filed: 1981-10-06
Abstract: An article is attached e.g. via a chain to a key 46 which is normally held inside a housing by spigot 50 engaging hole 48. It is released by insertion and rotation of second key 54, whereupon this second key is locked inside the housing and cannot be removed until the first key 46 (with its attached article) is replaced and rotated back to the illustrated position. As shown insertion of key 54 pushes sprung lever 40 out of notch 34 in bar 24, and rotation turns cog- wheel 28 to move the bar and also causes the key to be held by spigot 58 entering hole 56 in the key 54. Longitudinal movement of bar 24 causes key 46 to rotate out of engagement with spigot 50, so that it may be withdrawn, and also permits lever 42 to engage notch 38 so that further motion of bar 24 is forbidden until key 46 is returned. An electrical system is also described. <IMAGE>

Title: Production of ceramic nuclear fuel pellets
Inventor: RIGBY FRANK
IPC: C04B35/64
Filed: 1981-10-19
Abstract: In the production of nuclear fuel pellets consisting essentially of uranium dioxide formed into compacts and sintered, magnesia is included in the compacts and the compacts are sintered first in a reducing atmosphere and then in an oxidising atmosphere, the reducing atmosphere being maintained until the temperature is high enough for grain growth to occur. By delaying the introduction of the oxidising atmosphere grain growth may be enhanced more than is to be expected from the resulting hyperstoichiometry in the uranium dioxide and the presence of the magnesia.

Title: Plant treatment device
Inventor: BALS EDWARD JULIUS
IPC: A01M21/04
Filed: 1982-07-08
Abstract: A plant treatment device comprises a cup-shaped body (16) with internal screw threads (17) in which is engaged a neck of a non- collapsible, closed liquid container (19), the container having external screw threads (18) on its neck to engage with said screw threads (17) on the body (16). The screw threads (17, 18) do not precisely match and thus define an air path (20) therebetween. A flange of a member (10) is sealingly trapped below said container neck in said body, the member (10) having a depending, cylindrical tubular portion extending out of the body and carrying a wick (11). A groove (15) in the flange of the member (10) allows air to pass along said air path (20) into the container, as liquid flows through the wick. A cap (13) is screw- threadedly engaged on the tubular portion of the member (10) and contains an O-ring (14). Tightening of the cap compresses the O-ring and thus a variation in the capillary force is produced by varying said degree of engagement of the cap on said tubular portion of the member 10. <IMAGE>

Title: Tubular underground cavity such as a traffic tunnel or pipeline
Inventor: FINSTERWALDER KLEMENS
IPC: E21D9/06
Filed: 1984-09-05
Abstract: Between the outer surface of the lining (1), which absorbs ground pressure, of a tubular underground cavity, e.g. a traffic tunnel, and the ground (9) there is provided a layer (10) of a mineral clay, e.g. bentonite, and water, which layer can be deformed plastically in the event of relative displacements between the ground and the lining and thus limits the reciprocal transmission of forces. With normal ground conditions the sealing action of the layer is above all utilised, so that the requirements of crack width limitation of the lining can be decreased. In areas prone to subsidence, in which longitudinal movements of the ground are to be expected to a greater extent than under normal ground conditions, because of the predeterminable, almost constant coefficient of friction of the material of the layer it is possible to limit the longitudinal forces and longitudinal deformation of the lining. <IMAGE>
