Abstract: RECOVERY OF LIQUID HYDROCARBONS FROM       OIL SHALE BY ELECTROMAGNETIC HEATING IN SITU              ABSTRACT OF THE DISCLOSURE          A method of electromagnetic heating in situ recovers liquid hydrocarbons from an oil shale formation containing kerogen in an inorganic matrix where the formation is substantially impermeable to fluids under native conditions.  A block of the oil shale formation is substantially uniformly heated in situ with electro-magnetic power to a temperature of about 275°C where there is pyrolysis of a portion of the kerogen to gas and shale oil at a pressure sufficient to overcome the capillary pressure of the shale oil in the matrix, thereby providing substantial fluid permeability to the formation.  The gas thereupon escaping from said block and the shale oil driven thereby are recovered, thereby further increasing the permeability of the formation.          The magnitude of the electromagnetic power is controlled to raise the temperature of the block relatively slowly to increase the rate of pyrolysis of the kerogen as the permeability of the formation increases to produce gas at pressures above the necessary to overcome the capillary pressure and below that at which there is substantial escape of the gas bypassing shale oil within the formation rather than driving the oil before it.

Abstract: PROCESS FOR PRODUCING COMPOSITE MATERIAL                              ABSTRACT A process for producing composite materials which comprises subject-ing particles of a malleable matrix material, i.e., a metal or alloy or the components of a matrix alloy and particles of a reinforcing material such as a carbide or an oxide or an intermetallic to energetic mechanical milling under circumstances to insure the pulverulent nature of the mill charge so as to enfold matrix material around each of said reinforcing particles to provide a bond between the matrix material and the surface of the reinforcing particle. The process is exemplified by the use of aluminum alloy as the matrix material and silicon carbide as the reinforcing particles. Reinforcing particles are present in an amount of about 0.2 to about 30 volume percent of total matrix and reinforcing particles. The invention is also directed to the product of the process.

Abstract: ABSTRACT OF THE DISCLOSURE    An electric resistance seam welding method and apparatus includes a continuous wire electrode which is passed successi-vely  over a first electrode reel and thereafter over a second electrode reel via a plurality of guide and deflection rollers, the outer surfaces of the wire confronting each other when passing over the reels and being pressed together by the reels by a predetermined welding force against interposed workpieces to be seam welded together. An electric current is applied so as to pass from the second electrode reel to the first reel through the wire electrode and the interposed work-pieces, and the wire electrode is motor driven for feeding the workpieces through the reels. A copper wire is utilized as the wire electrode and has a tensile strength at the elastic limit of between 11 and 13 kg-f/mm2 and has a percentage elongation at break of 26 to 17 %. The reels are pressed to-gether by a force of 60 to 70 kg, and the copper wire is subject to a tensile stress of less than 10 kg-f/mm2 while passing over and between the reels. The reels are maintained at an operating temperature of 10 to 30° C as the wire elec-trode passes thereover, so that a maximum elongation of the wire of 6 % when passing over the first reel, and a maximum further elongation of the wire of 6 % when passing over the second reel, is attained.

Abstract: Abstract A bow-forming ribbon has a decorative flexible ribbon member and a drawstring connected loosely to the ribbon at points along its length by relatively stiff retainer members.  Each retainer member extends generally transversely across the ribbon member, and each is inclined with respect to the transverse direction at an angle.  Each retainer member is inclined at an angle different from that of the preceding retainer member.  On forming the ribbon into a bow by pulling the drawstring relative to the ribbon, the inclined retainer members tend to skew the adjacent loops or segments of the bow relative to one another, so that loops distributed at various angles around the axis of the bow are formed, thus avoiding the tendency for the successive loops to seat themselves on one another in a fan shape.

Abstract: Abstract A hoist mechanism is provided that includes a first and a second lifting arm connected at a first pivot point, a hydraulic cylinder connected to said lifting arms, and a stop means located on one end of the second lifting arm.  During the initial lifting of the hoist mechanism the first arm remains stationary as the second lifting arm rotates around the first pivot point.  The hoist mechanism functions in this manner until the two lifting arms reach a predetermined angle with each other.  When the lifting arms reach this angle, the stop means acts to convert the action of the hoist mechanism into that resembling a scissors hoist, with both lifting arms rotating, as the hoist mechanism is further extended.  The hoist mechanism is designed such that the effective length or the second lifting arm is constantly increasing as the second lifting arm rotates from the rest position to the predeter-mined angle.  This is accomplished in certain embodiments by the stop means including a shaft attached to the dump bed and a track which is a part of the second lifting arm.  The shaft and the track function as a slidable connection which trans-mits the weight of the dump bed and its payload onto the hoist assembly.  The shaft is confined within the track and moves back and forth therein as the dump bed is raised and lowered.
