Abstract: Abstract of the Disclosure A system for the formation and use of a bore hole, partic-ularly for the recovery of oil from an oil-bearing under-ground formation.  An eversible elongate permeable tube, preferably formed of woven cloth, including outer and inner walls, connected at a rollover area, is urged into the formation by a driving fluid.  Drilling fluid is pumped through a central passageway in the tube and carries a central pipe forward.  The drilling fluid assists break-up of the formation to form a cuttings slurry which passes back along the outside of the eversible tube.  Means is provided for turning the tube, as from the vertical to the horizontal, by use of a turning segment in the eversible tube.  Such pipe preferably includes a flexible helical segment capable of turning and of serving as the ultimate support casing.  Also, gravel packing techniques.

Abstract: Abstract Of The Disclosure A grip for pulling cable, especially fragile cable such as fiber optic cable.  The grip can pull such fragile cable with or without a fragile connector at the end thereof. The grip com-prises a rigid, hollow protective sheath with an open tail end for receiving the cable end therein, a pulling device coupled at the lead end of the sheath, and a braided open wire mesh sleeve coupled at the tail end of the sheath for engaging the cable upon a longitudinal stretching thereof which radially reduces the sleeve around the cable.  The pulling device can be a flexible wire loop rotatably coupled to the protective sheath.  The open wire mesh sleeve can be closed along its length, split along its length or both closed and split in the two sections along its length.  A method of inserting the fragile cable with a fragile connector at the end includes the steps of inserting a hollow rigid tube into the sleeve, inserting the fragile connector into the tube, removing the tube from the sleeve, maneuvering the con-nector into the protective sheath and radially reducing the sleeve by stretching.

Abstract: 809 . ?N     INVENTOR:       FRANZ VOGLER     INVENTION:      APPARATUS FOR CLEANING SOLDERING IRON BITS     ABSTRACT OF THE DISCLOSURE     For cleaning hot soldering iron bits which are contaminated or soiled by tin oxides and soldering residues a flat felt or sponge has often been heretofore used.  This cleaning technique is impractical, incomplete and frequently causes spatters of soldering tin or pewter at the place of work.  This is unacceptable, especially when precision soldering electronic devices.  This problem is solved by using an apparatus driven by an electric motor.          The hot soldering iron bit or tip is momentarily placed between two cleaning bodies which rotate towards each other.          These two rotating cleaning bodies thus enclose the soldering iron bit and protectively clean the same.  The cleaning bodies are mounted in a removable holder or cage provided with a tin collection container or receptacle.  For enhancing the self-cleaning action of the two cleaning bodies the spacing between the axes or shafts of the two cleaning bodies is smaller than the mean diameter of both cleaning bodies.          Additionally, two strippers or scrapers engage into each cleaning body.

Abstract: ABSTRACT OF THE DISCLOSURE    In a trailer having two steerable wheels, there is provided a device which, in response to the lateral acceleration of a turn, applies a steering force to the wheels such that the tires generate a side force toward the center of the turn which is equal and opposite to that of the trailer resulting from the acceleration.  As a consequence, no net force is exerted on the tow vehicle by the trailer, preserving its handling characteristics. The application is either through a mass on the trailer, or through use of the mass of the trailer itself.                  * * * * * * * * *

Abstract: ABSTRACT OF THE DISCLOSURE:           The present invention relates to a process for the purification of hexamethyldisiloxane, which is rendered impure by toluene or other solvent which may not be completely separated distillatively from hexamethyldisiloxane.  The process may also be used in like manner for purification of hexamethyldisiloxane which is rendered impure by other sub-stances.  It is based upon the fact that hexamethyldisiloxane forms with acetonitrile a hitherto unknown azeotrope.  This azeotrope forms a heavier acetonitrile-rich phase and a lighter hexamethyldisiloxane-rich phase, which are not miscible with one another.  This azeotrope boils already at 71.4°C and makes possible in this way separation of hexamethyl-disiloxane from its impurities at relatively low temperatures.          Moreover one or more entraining distillations are carried out in the presence of excess acetonitrile and the acetonitrile is again separated off distillatively from the lighter phase thus produced.  In addition to the above indicated azeotrope systems there is also provided an azeotrope system of hexamethyl-disiloxane and toluene as ?ell as a further one of acetonitrile and toluene.  All three azeotrope systems are likewise the subject of the present invention.

Abstract: #1601 CYCLOIDAL SONIC MILL FOR COMMINUTING MATERIAL SUSPENDED IN LIQUID AND POWDERED MATERIAL          ABSTRACT OF THE DISCLOSURE    An annular treatment chamber is formed by a gap between inner and outer inertial ("inductively reactive") members.  At least one of these members, typically the inner one, is vibratorily driven cycloidally in an orbital path, which is typically circular or elliptical, at a frequency of the order of 50-500 cycles per second The granular material to be comminuted may constitute material suspended in a liquid or may be in particle form.  This material is continually fed into the annular gap and exited therefrom after comminution has been accomplished.  While in the annular gap, the material is driven circumferentially around the annular chamber with a high shear force while being subjected to radial vibratory forces developed therein.  The fluid material is thus simultaneous-ly subjected to high forces of cyclic nature having both shear and radial components which tends to effect cavitation in liquids and high comminution forces in powdered material to effectively commin-ute both types of material in the case of liquid material, effec-tively comminuting the solid particles into a colloidal suspension in the liquid.

Abstract: ABSTRACT OF THE DISCLOSURE     A positive drive and an improved clutch actuating mechanism for use therein is disclosed.  The positive drive has a housing (10) retaining a pair of spaced drive clutches (54 and 56) which lock a pair of axles (18 and 20), respectively, to housing (10) for one-to-one rota-tion.  The clutches are moved from the disengaged to the engaged mode by axial movement of drive couplings (30 and 32) which include cam members (38 and 40) respectively. Input torque is transmitted from the housing to the cam members by means of a shaft (48) and the axial forces required to engage the clutches are transmitted from the shaft to the cam members through engagement of a shaft cam surface (49) and a ramp cam surface (51).  In accordance with the invention, the engaging cam surfaces are defined by a common locus of generating lines (101-106) such that the cam surfaces are in surface-to-surface contact, rather than line contact or point contact, over the entire range of pivotal movement of the shaft, relative to the cam mem-bers.
