Title: Nestable container
IPC: B65D21/02
Filed: 1971-11-23
Abstract: 1364880 Nestable containers; containers; discharging articles REYNOLDS METALS CO 23 Nov 1971 57393/73 Divided out of 1364879 Headings B8D B8C and B8S A nestable container formed in one piece of sheet material comprises a planar top flange 13 joined by a downwardly and inwardly-curled edge portion 14B to a toroidal bead 15, which is curled in the opposite sense to the edge portion and spaced below the plane of the flange. The bead reinforces the flange and is adapted to support the container on the flange of a like container when nested therewith. The container may be of metallic foil, e.g. aluminium, or a laminated construction using paper, foil and plastics in any desired combination. The foil container may be provided with external thermosetting coating or layer and an internal thermoplastics coating to which a closure 22 may be heat-sealed, Fig. 3 (not shown). A reclosure cap 23 is provided for closing the container after the closure 22 has been removed. The lowermost of a nested stack of the containers may be released by dispensing apparatus comprising a reciprocable yoke having arm end portions 26 supporting the stack and arm intermediate wedge-shaped portions 31 adapted to engage between the beaded flanges of the two lowermost containers to release the bottom container while supporting the rest of the stack on movement of the yoke in the direction of arrow 33. On reverse yoke reciprocation, the stack is moved back on the arm end portions to permit the procedure to be repeated. A method and apparatus for forming the container is described and claimed in Specification 1,364,879 (Division B3).

Title: Improvements in steam-heated oven installations
IPC: F24C7/00
Filed: 1947-01-07
Abstract: 605,905. Steam-heated receptacle chambers &c. BRITISH OVERSEAS AIRWAYS CORPORATION, and SAUNDERS, F. S. Jan. 7, 1947, No. 581/46. [Class 28(i)] A steam heated chamber for receptacles specially designed for aircraft comprises a thermally insulated heating system including a boiler, the rising steam from which circulates through an oven supporting therein a number of food containers, most of the condensed steam being collected to flow by gravity to a sump before entering the boiler through an opening below the normal liquid level in the boiler. The apparatus may also be used for warming frozen foodstuffs. The boiler 49 heated by an electric immersion heater supplies steam through pipes 58 to the jackets 65 holding the food containers 45. The boiler also supplies steam to a storage tank 67 providing hot water for washing up. Boiling water for tea may be drawn from the boiler through a cock 81 which can be swivelled up and enclosed behind the doors 53 which close a recess for warming plates. Condensed steam from the outside of the food containers trickles through holes 90 into a trough 47 leading to the boiler sump 48. The boiler is about six pints capacity but normally holds only two pints to allow room for generation and escape of steam. The steam supply is controlled by hand operated gate valves 61. The apparatus is surrounded by a lagged casing 43 having a lagged hinged lid 46. The food containers are suspended by their flanges on cork gaskets 50 in the cover plate 44 and have covers 55 and side handles. A pipe 72 heats the storage tank by steam which when condensed runs out of the ends of the pipes 72 through holes 90 and trough 47 to the sump 48. The bottom of the sump opens into the boiler so that condensate may return to the boiler to complete the circulatory system. A temperature gauge 82 is connected to a thermal responsive element 83 in the boiler. A pipe 84 connected to the sump leads to a water level gauge. The storage tank 67 and the boiler 49 may be replenished from a leader tank (not shown) one connector leading directly to the storage tank, the other arranged to discharge water into the trough 47. A small blow off valve is fitted in the top of the oven.

Title: Quickly Bringing a Second Source of Direct Current into Operation to Continue to Supply a Load when a First Source of Direct Current Previously Feeding it has Failed.
IPC: H01H33/59
Filed: 1966-12-29
Abstract: 1,162,505. Emergency power supply systems. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION 29 Dec., 1966 [29 Dec., 1965], No. 58242/66. Heading H2H. A load 1 is normally supplied from a D.C. source 6, 7, the failure of which causes a thyristor 15 to become conductive to allow the load to be supplied from an auxiliary D.C. source, such as a battery 9. Failure of the source 6, 7 causes de-energization of a relay 21, whereupon contacts 22 close, but the operation of the relay is slower than that of the thyristor. Closure of contacts 22 render the thyristor non-conductive but the auxiliary supply to the load 1 is maintained over the contacts. When the main D.C. source 6, 7 is re-established, the relay 21 is energized to open contacts 22 and the thyristor 15 remains non-conductive. A device 23 is provided to protect the thyristor from reverse voltage and a source 10 is provided to charge the battery 9. A diode 18 prevents the auxiliary source feeding into the main source and a Zener diode 16 is provided to prevent the gate cathode potential of the thyristor becoming too large. In a second embodiment the auxiliary battery is divided into two parts which are connected in series by the thyristor to supply the load upon failure of the main source, but which are connected in parallel and arranged to be charged from the main source when this source exists.

Patent GB-2004971-A (GB)
Title: Protective sheathing of tubes
IPC: F16L58/16
Filed: 1978-09-19
Abstract: A tube 1 is provided with a protective sheath by applying cement mortar 3 or a mixture of cement mortar and fibres to the outer wall of the tube, while the tube is slowly rotating, and wrapping the mortar with a banding element 4 wound about it. The use of impervious sheet material for the banding element has the advantage that it forms a closed outer skin and hinders the evaporation of mixing water in the mortar, rendering subsequent treatment unnecessary, also that it protects the mortar from media which have a corrosive action on cement. The use of a fleece, an unwoven fabric or a woven fabric has the advantage that the banding element presses into the cement slurry and forms a common layer therewith; sealing and protection against corrosive action can then be achieved by applying a bitumen or plastics material coating. <IMAGE>

Title: Improvements in or Relating to Rotors
IPC: F01D5/14
Filed: 1978-10-20
Abstract: To simplify the production of a rotor for turbomachinery requiring blades which are markedly curved at their point of attachment to the rotor hub, the desired curvature is achieved by subjecting the rotor to a torsional couple whereby the blade roots are caused to adopt the desired curvature. In the simplest case the rotor is firstly performed with substantially straight blades and the internal profile of the rotor hub appropriately shaped to ensure the desired relative displacement. Twisting of the whole length of the rotor may be followed by annealing, and then twisting of a part of the rotor. <IMAGE>

Title: Distribution system
IPC: B65G47/53
Filed: 1978-11-28
Abstract: Distribution system for feeding foodstuffs, sweets or other similar material to a number of weigher packer units or other outlets according to demand without re-circulation or long- term storage utilises a series of main vibratory conveyors 10-13 to carry the material along a main feed path, each outlet 31-38 being fed by a separate and independently driven branch conveyor 15-22 whose conveying surfaces bridge gaps between the main conveyors but are not vibrated thereby. When the branch conveyors are inoperative the main flow is carried across their surfaces by the impetus imparted by the associated main conveyor. On demand from the associated outlet the branch conveyors are operated to divert all or part of the main flow laterally from the main feed path. The conveyors are controlled on a demand basis by transducer devices 40-46 acting as level probes positioned along the main feed path. The branch conveyors may be vibratory or endless belt conveyors. <IMAGE>
