Title: Flask Gauge.
IPC: B07C5/12
Filed: 1966-08-17
Abstract: 1,160,759. Detecting surface irregularities. OWENS-ILLINOIS Inc. Aug. 17, 1966 [Aug. 23, 1965], No. 36756/66. Heading G1M. A gauge for detecting an excessively bulged or sunken side surface 12 of a flask or similar container comprises reference fingers 21 adapted to contact the wall of said containers for guiding an advancing upright flask along a prescribed horizontal path, a plurality of horizontally movable electrically conducting feeler fingers 22 vertically arranged in a series at one side of said path and means for yielding by urging the fingers into contact with one of said container side surfaces. In the embodiment described the gauge is mounted on a framework above a conveyer 10 which carries the flasks. The gauging and reference feelers are supported by an adjustable bracket 16 one set of feelers on each side of the conveyer and the fingers are mounted for rocking movement on a pivot rod 23. The reference fingers orientate pairs of gauge rods 25 which co-operate with the gauge fingers 22 to close an electrical circuit if the flask is faulty. There are two gauge rods for each set of feeler fingers 22, each gauge rod having a flat surface 25 at Figs. 6 and 7 (not shown) for contact with the feeler fingers, one rod contacting the fingers when the flask side surface bulges and one when the side surface is sunken. When the electrical circuit is closed, a reject solenoid valve is operated which permits flow of air under pressure through nozzle 35 Fig. 5 (not shown) across the path of the flasks, to eject the faulty container.

Title: Sintered bearings and methods of making them
IPC: B22F7/04
Filed: 1961-10-18
Abstract: In a process of producing a porous sintered bearing a metal powder mixture comprising copper and not greater than 43% of lead is distributed on a support such as steel and sintered at 882-954 DEG C. in a non-oxidizing atmosphere containing not more than 0.1% carbon dioxide and having a dew point of less than 5.5 DEG  C.  The mixture may also contain up to 2% by weight of the copper of metals such as tin, antimony and zinc and the powder mixture should be finer than 100 mesh or 130 mesh.  Sintering is carried out in hydrogen, cracked ammonia or a methane atmosphere.  The steel backing may first be coated with copper and the sintered bearing may be plated with tin or indium or hot dipped in tin, indium, antimony or alloys of these with lead.  Alternatively, the powder mixture may be sintered on a non-adhering surface such as oxidized chrome steel or graphite to form a self-supporting porous bearing.

Filed: 1930-12-12
Abstract: 366,211. Tumbler switches. ARNOLD, C. L. and M. K. ELECTRIC, Ltd., Wakefield Street, Edmonton, London. Dec. 12, 1930, No. 37542. [Class 38 (v).] A tumbler switch has an actuating member 14 and a contact-member 11 pivoted at 10 to the bridge. Pins 17, 18 are carried respectively by the actuating and contact members and are embraced by an endless coiled spring 21. A plate 24 has a slot 25 which engages the pin 17, and a slot 26 which engages the pin 18. A third slot 29 allows for movement of the plate relative to the pin 10. Extensions 27, 28 engage the underside of the bridge during the sliding action of the plate. In action, the pin 17 moves the plate 24 causing the end of the slot 26 to move the pin 18 thus positively moving the contact-arm 11 across the deadcentre. Extensions 22, 23 on the contact-arm engage the bridge to limit the movement in each extreme position. Specification 350,615 is referred to.

Title: Improvements in and relating to addressing machines
IPC: B41L47/46
Filed: 1930-12-13
Abstract: 363,819. Addressing - machines. SKREBBA-WERK METALLWAREN GES., 17, Hilda Strasse, Freiburg, SKREBBA, H., 10, Neuwerkhof, and KAMMER, K., 3, Kanalweg, both in Lahr, both in Baden, Germany. Dec. 13, 1930, No. 37688. Convention date, Dec. 13, 1929. [Class 100 (ii).] In an addressing- machine of the kind comprising a printing-plate magazine combined with a rotary drum adapted to carry the plates to printing position, each plate after use is discharged into a guideway leading to the top of the magazine, whereby the plates travel in a closed circuit and may be used repeatedly. As shown, printing-plates c stacked in a magazine b and carried round to printing position by a drum k are detached from the drum by the end d of a guide channel f which directs the plates back into the magazine. The part d may bo in the form of a pivoted member adapted to be moved into an inoperative position so as to allow repeat impressions of any desired address and, incidentally, to close the channel f so as to prevent the lowest plate from dropping out ; alternatively, the part d may be in the form of a slidable member mounted in grooves on the channel. The side edges of the printing-plates engage grooves in the channel, and the plates are therefore bent to the curvature thereof ; alternatively, to avoid this bending and to reduce friction, the plates may have laterally-projecting pins riding in the channel grooves. The channel is provided, also, with retaining projections or springs to prevent reverse movement of the plates. The magazine b may be removably mounted in a frame l rigid with the channel f, and the member l may swing into an inoperative position about a vertical pivot bolt at one side of the apparatus or about a horizontal pivot, or it may slide horizontally axially of the drum or at right-angles to that direction. A pin o normally engaging a hole r in the frame l, and preventing movement thereof, is spring-pressed towards a rotary adjustable cam p provided with a notch t whereby the pin is released in a predetermined position of the drum. The machine may print constant matter in combination with the addresses, e.g. the member k may be the drum of a rotary duplicator. The Specification as open to inspection under Sect. 91 (3) (a) states that the channel f may be arranged in an oblique direction relatively to the magazine b or shaped to discharge into the magazine through a curved portion of large radius. This subject-matter does not appear in the Specification as accepted.

Filed: 1973-08-10
Abstract: 1402496 Fuel elements ATOMIC ENERGY OF CANADA Ltd 10 Aug 1973 [1 Dec 1972] 37988/73 Heading G6C A nuclear fuel element having a sheath of Zr or a Zr-alloy is provided with a crosslinked siloxane lacquer coating on the inner surface of the sheath as an interlay between it and the fuel. A silicone grease is first applied as a thin layer in the sheath and then baked at 300‹ C. in a partial vacuum, with oxygen present, so that oxidative cleavage of the side chains of the grease occurs to form a crosslinked siloxane lacquer coating bonded to the sheath. The partial vacuum removes hydrocarbon products emitted by the silicone grease during the heating. Uranium dioxide fuel pellets are subsequently stacked in the sheath in an argon atmosphere. The siloxane lacquer coating retards cracking of the sheath by iodine vapour emitted by the fuel during burn-up and acts as a lubricant for the fuel to prevent rupture of the sheath by thermal ratchetting of the fuel against the sheath caused by differential thermal expansion between the fuel and the sheath.
