Abstract: ABSTRACT OF THE DISCLOSURE An elongated base if provided including a pair of opposite side opposing fulcrum surfaces disposed in a plane extending therebetween trans-versely of the base.  A pair of elongated longitudinal side-by-side levers are disposed between the fulcrum surfaces and include opposite end portions projecting from opposite sides of the aforementioned plane.  A first pair of end portions define opposing jaw faces for clamping an auto body portion therebetween and anchor structure is carried by the base for applying a pulling force thereon in a direction opposite to the direction in which the first end portions project.  The elongated levers, when retracted in said opposite direction relative to the base, are longitudinally slidable relative to each other when the second pair of end portions are spaced apart and structure is provided for interlocking the levers against longitudinal displace-ment relative to each other when the second pair of end portions are forced together by engagement of the fulcrum surfaces on the remote sides of the levers as the result of the levers being displaced relative to the base in a direction to advance the first pair of end portions of the levers.  The remote surfaces of the levers are slightly divergent toward the second end portions thereof and displacement of the levers relative to the base to advance the first pair of end portions of the levers causes the fulcrum surfaces to apply clamping forces to the remote surfaces of the levers centrally intermediate their opposite ends.

Abstract: ABSTRACT OF THE DISCLOSURE     An electrophotographic recording material is disclosed including an electrically conductive support, and a photoconductive layer comprising an organic photo-conductor, a binder, a sensitizing dyestuff and con-ventional additives.  The recording material can be imaged with an argon ion laser and has a sensitivity in the blue spectral region to prevent blue lines and markings used on paste-up register sheets from appearing on the electrophotographic printing plate during copying in a reprocamera. Additionally, the sensitivity in the yellow spectral region prevents yellowed originals from being produced with background. Finally, the material is in-sensitive in the red spectral region so that it can be handled in the red light of a darkroom.

A downhole sonde is provided with an acoustic tansmitter and at least one acoustic receiver.  The trans-mitter is repetitively driven with a unique or charac-teristic swept frequency signal.  Propagated acoustic energy detected at the receiver is cross-correlated with the characteristic transmitter swept frequency signal to provide indications of the arrival of various modes of acoustic energy propagation at the receiver.  Logs as a function of borehole depth of the speed of propagation of the various modes of propagation may be derived.     -I-

Abstract: Abstract Of The Disclosure In a formed coke process of the type in which carboni-zation and calcination of coal is carried out prior to briquet-ting, the hot calcined char is cooled by means of a hydrogen-rich gas at superatmospheric pressure so as to effect concurrent cooling and desulfurization of the char.  High sulfur coal containing 1.5 to 4 wt.% sulfur can be used while obtaining a char and a formed coke product with a sulfur content of 0.8 wt.% or less.  The cooling can be done in two stages:  (1) a first stage in which sulfur removal and cooling to a temper-ature not lower than about 800°F are accomplished with a hydrogen-rich gas, and (2)  a second stage in which further cooling to about 200°F or less is accomplished with an inert gas.

Abstract: ABSTRACT A labelling station in a labelling machine, more particularly for bottles, has one or more glueing segments mounted upon a carrier driven in rotation.  The axes of rotation of the segments are arranged, upon the carrier, between the centres of curvature of their pick-up surfaces (which are curved cylindrically with a radius shorter than the distance between the axis of the carrier and the gripper cylinder) and the pick-up surfaces, and move in a circular path concentric with the axis of the carrier.  The carrier, gripper cylinder, and glueing segments are coupled together, by a step-up and a non-uniform transmission, in such a manner that they rotate in the same direction. The said glueing segments carry out an accelerated or a retarded rotary motion in the opposite direction in such a manner that their pick-up surfaces roll off upon the glueing roller, the labels, and the gripper cylinder.  The labelling station is designed for selective operation with one or more glueing segments, and the step-up and non-uniform transmissions are exchangeable in such a manner that the step-up ratio of the transmission between the carrier and the gripper cylinder is inverse to the number of glueing segments on the carrier and of the divisions of the gripper cylinder.  The non-uniform transmission is in the form of a hypocyclic drive, each rotary wheel of which is rigidly coupled to the drive-shaft of the removal element and comprises drive-pins, while the stationary ring-gear comprises teeth with flanks varying in steepness according to the acceleration or retardation of rotation required for the rolling motion of the glueing segments at individual stations.  At least that section of the ring-gear which operates in the vicinity of the gripper cylinder, is exchange-able.

Abstract: Abstract of the Disclosure When a door of a microwave oven is opened during a programmed cooking operation, a door open monitoring circuit provides a door open signal to a microcomputer so that the microcomputer interrupts to execute the programmed cooking operation.  A control circuit measures time lapsed from the re-closure of the door to provide the microcomputer with a control signal indicative of whether a cooking switch has been operated within a predetermined period of time after the re-closure of the door.  In response to the control signal, the microcomputer executes the remaining programmed cooking operation in case that the cooking switch has been operated within the predetermined period of time or clears it otherwise.  The function of the control circuit may be performed by the microcomputers.

Abstract: Abstract of the Disclosure Carbon fibers are provided which bear an improved finish coating upon the surface which is capable of withstanding the high temperatures (e.g., above 500°F.) commonly encountered during the formation of composite structures employing a poly-imide matrix. The sized carbon fibers prior to the curing to form a rigid polyimide coating are flexible, may be readily handled without significant damage, and are amenable to good impregnation with the matrix resin thereby facilitating the for-mation of quality composite structures.  The finish comprises a mixture of selected precursors for the formation of a rigid poly-imide (as described).  More specifically, the size composition is formed from at least one aromatic diamine, at least one aromatic dianhydride, and at least one aromatic tetracarboxylic acid diester.  A film-forming polyamic acid oligomer readily forms and is present as an intermediate reaction product within the finish coating and the aromatic tetracarboxylic acid diester has been found to beneficially serve primarily as a flexibility preserving diluent during the early stages of the polyimide-forming reaction which takes place within the finish coating.  The finish is fully compatible with a polyimide matrix.
