Abstract: CONVERSION OF SYNTHESIS GAS WITH IRON-CONTAINING FLUID CATALYST                           ABSTRACT      A method is disclosed for the conversion of synthesis gas to a liquid hydrocarbon product having a boiling range of less than 204-44°C (400°F) at a 90% overhead and containing approximately 5-25% of an aromatic product.  The novel method involves contacting synthesis gas with a single particle catalyst containing iron, a crystalline acidic aluminosilicate zeolite having a silica-to-alumina ratio of at least 12, a pore size greater than about 5 Angstrom units, and a constraint index of about 1 to 12, and a siliceous matrix.  The catalyst does not contain promoters and the alumina content of the matrix is limited.

Abstract: Abstract of the Disclosure A seal of the type resembling a padlock and compris-ing a plastic housing having two portions joined only by a frangible portion, each of the housing portions having an aperture for receiving an end of a shackle.  In the illus-trated and preferred embodiment, the weakened portion is disposed at the bottom of a narrow elongated recess formed by adjacent housing portions, to minimize the effect of exposure to sunlight on the weakened portion.  The seal can be easily fractured along the weakened portion, unintention-ally, by unauthorized persons trying to remove the seal without destroying it, and can be easily fractured inten-tionally by authorized service personnel to facilitate removal.  In an embodiment of the invention in which the shackle is a wire having reverse bent end portions, which end portions are each maintained in a flexed condition, when assembled into the housing opening, and in which the two housing portions are connected only by a centrally disposed thin web, attempts to remove an end portion will cause the extreme end of the reverse bent portion to pierce through the wall of the housing and start a fracture in the thin connec-ting web, which provides evidence of tampering, and often causes the web to break, allowing the housing portions to separate, giving obvious evidence of tampering.

Abstract: ABSTRACT OF THE DISCLOSURE         A batch type automatic icemaker adapted for instal-lation in the freezing compartment of a refrigerator is provided with a thermal member having first and second ends.  The first end of the thermal member is in communication with at least one of the ice-forming cavities and positioned below the water level.  The second end projects into the cold air within the freezer.  The second end is of a sub-stantially larger mass than the first end.  Since the first end is of a small mass relative to the second end and is thermally isolated from the mold, the cold freezer air cools it at a much faster rate than the water in the mold or the mold itself.  The cooler surface of the first end chills the water in contact with it with a minimum of supercooling.

Abstract: PLASMA SPRAY METHOD AND APPARATUS     ABSTRACT OF THE DISCLOSURE      A plasma spray method capable of directing plasticized powders against a substrate for deposition of a protective coating thereon is disclosed.  Various structural details of the apparatus described enable the attainment of high particle velocities without melting the particles.  The technical con-cepts employed are directed to normalizing the temperature of the plasma stream at a reduced value prior to the injec-tion of coating particles.  A general reduction in tempera-ture and substantial elimination of a thermal spike at the core of the stream are achieved.  Coating particles are injected into the plasma stream only after the plasma is first cooled and then accelerated.  In detailed embodiments, a nozzle extension assembly having a plasma cooling zone, a plasma acceleration zone, a powder injection zone and a plasma/powder discharge zone is affixed to the downstream end of a conventional plasma generator.

Abstract: ABSTRACT     A process and apparatus are provided controlling the heat input of an extractive distillation column.  The bottom of the column is heated with a major stream of thermal energy which is either slowly varying in time or controlled by the amount of starting material mixture and with a minor stream of thermal energy which is controlled by sensing the thermodynamic state in the upper half of the column during the process.  The major stream can provide about 90 percent and the minor stream about 10 percent of the heat fed to the column.  The minor stream can be controlled by the temperature at one point in the upper half of the column, by the temperature difference at two points in the upper half of the column or by gas chromatographic analysis of the extract material concentration near the top of the column. The process allows to keep the concentration of the extract material in the raffinate low.

Abstract: ABSTRACT Disclosed is a torque transmitting and blocking device which includes a cylindrical drum, a pair of arcuate shoes positioned within the drum, and a spanner bar or ring extending between the shoes to one side of the axis of the drum.  On the other side of the drum axis the shoes are displaceable toward each other and may conveniently be lightly biased apart.  The shoes have sur-faces, which may include holes, lateral or transverse projections, or the ends of the shoes, through which rotative forces may be transmitted from sources external of the drum and through which the shoes may retransmit such forces. Application of a rotational force through such a surface into a shoe in a direc-tion tending to displace the shoes toward each other results in rotation of the shoes and bar within the drum, and consequent transmission of torque, if desired, out of the drum through another shoe surface.  Application of a rotational force into a shoe in a direction tending to displace the shoes away from each  other throws the shoes into a jamming relationship with the wall of the drum and prevents transmission of torque past or through the device.  Applications of the device in apparatuses for winches, stepping clutches, and automatic load holders are disclosed.

Abstract: ABSTRACT         An apparatus for changing the leverage of a bicycle pedal by telescoping the pedal on the pedal arm during rotation of the pedal arm and pedal guide around the pedal axis; the apparatus comprising a pedal guide which includes a lead bolt and has the pedal attached thereto, a pedal arm, a cam plate, a cam ring, a ring bearing, a pedal axle, a sprocket, and a spindle housing.   The lead bolt of the pedal guide rotatably attaches to the cam ring which peripherally enclosed the ring bearing.   The ring bearing is peripherally located around the cam plate thus enabling the cam ring to rotate with respect to the cam plate.   As the pedal arm and pedal guide rotate, the cam ring and cam plate control the telescoping motion of the pedal and pedal guide by controlling the movement of the lead bolt of the pedal guide.   The pedal guide slides on the pedal arm.   The sprocket is fixedly connected to the pedal axle.
