Abstract: An elongated trough is slidably located on a vertically pivoted trough to carry pipe from a derrick floor to a pipe rack when there is little or no height differential between the derrick floor and the pipe rack. The slidable trough may be removed when the height differential is such that pipe will slide down the vertically pivoted trough by gravity.

Abstract: A plantain impregnated with fruit juice, particularly orange juice, having a unique taste and texture. Plantains are selected with ripeness such that the sugar content is derived from at least 70% conversion of the starch to sugar, peeling the plantains and then apply a high vacuum to the plantains. The plantains are then immersed in a solution of fruit juice. After holding the vacuum for a time, the plantains are held immersed in the fruit juice under superatmospheric pressure for a sufficient dwell time to substantially completely impregnate the plantains which are then removed and frozen. The plantains prior to impregnation are desirably preserved from fungus attack by ripening the plantains in a low humidity of about a maximum of 40% relative humidity and/or contacting the plantains with a fungicide, such as that containing chlorine.

Abstract: This invention relates to a process for the extraction of oilseeds and oilseed materials with two mutually immiscible solvents, the first solvent comprising a lower alkanol containing dissolved ammonia, and the second solvent comprising a lower alkane or halogenated lower alkane. The process yields two improved products, a proteinaceous meal of reduced glucosinolate content and a high quality triglyceride oil, both acceptable as food ingredients.

Abstract: Passivated coprecipitated nickel-alumina catalysts are provided which require minimal reactivation treatment for use as primary steam reforming gasification catalysts and no reactivation treatment when used for catalyzing methanation reactions. The catalysts are prepared by conventional coprecipitation techniques but are calcined at temperatures in excess of 480.degree. C. and reduced at temperatures less than 600.degree.. Passivation is effected by conditioning at 175.degree. to 200.degree. C. in carbon dioxide.

Abstract: Bodies of silicon nitride are produced by enclosing a silicon nitride powder in a gas-tight glass casing and subjecting the casing to isostatic pressure using gas as a pressure medium at a temperature of at least 1600.degree. C. and a pressure of at least 100 MPa. The casing is a glass having a high softening point. The casing is evacuated and sealed before compressing. The product may be pre-formed by isostatic compacting at a pressure of at least 100 MPa at a temperature considerably below the sintering temperature. The casing is cooled at a rate of at most 1000.degree. C. per hour and at a pressure of not over 10 MPa.

Abstract: An apparatus for transferring tubulars between pipe racks and a drilling rig floor including a stationary trough located below and extending towards the drilling rig and a movable trough aligned with the stationary trough having one end supported on the drilling rig floor and the other end powered to move between a lower position for transferring pipe to and from the stationary through and on upper position for transferring pipe to and from the drilling rig floor. A carriage having a frictional coating and wheels which run on guide structure below the stationary trough pushes and guides the pipe along the stationary trough. An endless chain system drives this carriage along the length of the stationary trough and includes a shock absorber system for dampening the forces on the carriage and chain when a pipe impacts the carriage. Two pair of legs extending between pipe racks and the stationary trough are provided.

Abstract: An object of ceramic or metallic material is manufactured by isostatic pressing of a body preformed from a powder of the metallic or ceramic material, the preformed body (10) then being embedded in glass, for example in a mass of glass particles (16) in a vessel (15) which is resistant to the temperature at which the sintering of the metallic or ceramic material is carried out, the material embedding the preformed body being transferred to a melt having a surface limited by the walls of the vessel, below which surface the preformed body is located, and a pressure necessary for the isostatic pressing of the preformed body then being applied on the melt by a gaseous pressure medium.

Abstract: In an axially telescopic coil carrier comprising a plurality of parts for receiving threads or yarns, wherein carrier elements extending from a respective ring element extend lengthwise of the coil carrier, from a substantially cylindrical surface and are guided for displacement relatively to each other, reinforced sections are provided near the ring members in which adjacent carrier elements are connected to each other by circumferential supporting elements. The free ends of the carrier elements project axially beyond these reinforced sections. At least a part of the supporting element of each coil carrier part projects, at least in that zone of the reinforced section which is remote from the associated ring member, radially no more than into the surfaces on which the inner edges of the free ends of the carrier elements of the adjacent coil carrier part are disposed. The supporting elements thus form radially effective supports for these free ends of the carrier elements.

Abstract: A tumbler lock having an outer cylinder and an inner cylinder rotatably mounted therein with springless plate-shaped tumblers which move freely in guide slots. Tumbler locks of known construction can be opened by unauthorized persons because an object can be inserted through the windows in the plate-shaped tumblers required for the insertion of the key, wedged against the side faces of the windows and the tumblers lifted from their locked state. This is foreclosed in the invention because the side flanks of the windows in the area of the key guide which are parallel to the direction of the motion of the tumblers are covered by protective strips connected with the inner cylinder.

Abstract: A pipe feeder for automatically moving pipe off of or onto the top row of a stack of pipe. A pair of stanchions are provided with a system for supporting a plurality of rows of pipe next to the stanchions such that the length of pipe is generally parallel to the plane of the stanchions. A pair of upright guides are coupled to the pair of stanchions respectively and a frame is coupled to the pair of guides for movement to different levels along the pair of guides. The frame comprises a pair of endless chains adapted to rest across the top row of pipe. Each chain has a plurality of feet attached thereto for engaging the pipe on which the pair of endless chains rest for moving pipe when the chains are driven. A driving system is provided for driving the pair of endless chains in unison in first or second directions for moving the pipe toward or away from the pair of stanchions.

Abstract: In a method of replacing a section of an old cast iron main with a new main of plastics pipe material, the section to be replaced is isolated from the adjacent live main after a by-pass is fitted between the section and the main. One end of the pipe is then pushed up the isolated section until a desired length is located within the isolated section and the other end of the pipe is connected to the end of the adjacent main. This enables the isolated section to be kept alive solely by gas flow through the pipe from the main and the by-pass can therefore be removed.
