Abstract: PROCESS FOR THE PREPARATION OF FIBER-REACTIVE DYESTUFFS       Abstract of the disclosure:      A process for preparing fiber-reactive dyestuffs has been described which leads to a mixture of a fiber-reactive phthalocyanine dyestuff and a fiber-reactive azo dyestuff.          This process utilizes the aromatic amine with the fiber reactive group, which so far was lost owing to an incomplete reaction in the preparation of the fiber-reactive phthalo-cyanine dyestuff by reacting phthalocyanine sulfochlorides with said aromatic amine and optionally other amines not containing any fiber-reactive group, for the preparation of azo dyestuffs, the amine acting as diazo component for these azo dyestuffs.  Accordingly, in this novel process phthalo-cyanine sulfochlorides are reacted with aniline or naphthyl-amine compounds, which contain as fiber-reactive group the vinyl sulfonyl, the .beta.-sulfatoethyl-sulfonyl, or the .beta.-hy-droxyethyl-sulfonyl group, and optionally with another amine in common manner to give the phthalocyanine dyestuff, and subsequently the unreacted portion of the aromatic amine with this fiber-reactive group is diazotized and coupled with a coupling component which leads to yellow azo dyestuffs.  In this manner a green to blue-green or olive-green dyestuff mixture is obtained.     These fiber-reactive dyestuff mixtures are suitable in common manner for the dyeing of cellulose fibers, poly-amide fibers and leather.  With the novel process, a com-plete utilization of high-grade dyestuff intermediates and furthermore a pollution control of production waste waters are ensured.

Abstract: A B S T R A C T             A fire ladder includes as opposite side a pair of elongate flexible cables in the form of interwoven strands of wire.   Hollow tubes flattened and scored on their upper surfacer extend rigidly between the cables to provide the ladder rungs.   The rungs have initially open ends into which looped portions of the cables are inserted.  One side wall of the rung is then crimped inwardly and pressed against the oppo-site wall to firmly clamp the cable within the rung.   Hook-like arms secured to the ends of the cables serve to suspend the lad-der from a window sill and may be folded by means of a hinge structure to a collapsed storage position occupying little space. A spring located within the hinge arms maintains the hook-like support spaced apart during use, while stops prevent the arms from pivoting excessively.

Abstract: ABSTRACT OF THE DISCLOSURE A power screwdriver for use with a flexible string of dis-connected screws retained in head to tip orientation by attachment to a continuous length of plastic, paper or similar flexible material. The string of screws feeds into a rearward section of a reciprocating shaft of the power screwdriver where the screws are individually ad-vanced into alignment with an engaging bit, the combination bit and shaft being continuously rotated during the course of use.  As the forward screw is prepared for engagement by the rotating bit, the retaining plastic or similar material is severed, leaving the for-ward screw free for emplacement.  The screw is engaged and advanced to a forward opening of the shaft by thrust pressure applied by the user to reciprocate the shaft rearward with respect to a power train which is keyed to continuously rotate the shaft and bit.  When the thrust pressure is withdrawn, a spring compressed by the rearward motion of the shaft returns the shaft forward to a stable position. In conjunction with this motion, a dog mounted within the shaft catches the head of a lead screw and carries it forward for engage-ment by the bit.  As the thrust pressure is sequentially applied and released, the constantly rotating bit engages and drives the severed screw into a wall or other receiving material.  This pro-cess may be repeated without interruption until the string of screws is exhausted.

Abstract: TELESCOPING SEATING SYSTEM WITH AUTOMATICALLY FOLDING CHAIRS           In a telescoping seating system having a number of rows  which may be moved between an extended or use position and a retracted or storage position, chairs or other seating is mounted on stanchions which are pivotally mounted to the rear of the deck in each row.  The stanchions are pivoted to an upright position when the system is extended for use and folded to a horizontal position when the system is retracted for storage by means of an actuator mechanism mounted to the forward portion of the next higher row and operative in response to relative movement between adjacent rows.  In this manner, the height of the seats is independent of the rise of the system for more comfortable seating  A torsion rod assembly is mounted beneath the seating to counterbalance at least some of the weight of the seating in the storage position.  Locking members engage the stanchions in the use position to secure the seating in the raised position.  The locking members are released in response to the closing motion between adjacent rows to permit the seating to be folded to the storage position in the space between adjacent decks.

Abstract: TITLE OF THE INVENTION               METHOD AND APPARATUS FOR MINING MINERALS, ESPECIALLY COAL FORMATIONS     ABSTRACT OF THE DISCLOSURE    Disposed herein is a new method and improved apparatus for digging and mining earth formations, especially coal formations.      A mining or excavating machine having a movable frame with a drive means mounted on the frame is provided with a rotatable structural member and a rotatable cutter support having cutter bits mounted thereon.  The structural member is rotatably mounted on the frame and connected to the drive means so as to be driven in one direction of rotation about a longitudinal axis of the structural member.  The rotatable cutter support assembly with the cutter bits mounted thereon is rotatably mounted on the structural member and is freely rotatable about its longitudinal axis.  The mining machine is then positioned so that the cutter bits will reduce the mineral formation by driving the structural member in one direction of rotation about its longitudinal axis.  Engagement of the mineral formation with the cutter bits then causes the freely rotatable cutter support to rotate about its longitudinal axis in a direction that is reverse to that of the power driven structural member.  This method of mining mineral formations, especially coal, allows the type cutter bits commonly used to penetrate and fracture the mineral formations without undue and unnecessary frictional engagement, eliminating unnecessary dust and sparks.    A new type cutter bit is also disclosed herein for use with the apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE Thermostatic sensor for controlling radiator valves either directly or by remote control, comprising a cup-like metallic vessel (1) with a compressible plastic bellows (3) and a means (6) for effecting control movements in response to expansion or contraction of the bellows.  The space between the vessel and the outside of the bellows is hermetically enclosed and filled with a wax medium (2) with high coefficient of thermal expansion. A sensor of this type is produced in one way by inserting wax in freely-fluid condition into the vessel (1), after which the bellows in compressed or sucked-together condition is dipped down into the fluid medium and is there allowed to expand again, after which the vessel is closed by means of a washer or the like. Another way of producing the sensor is by dipping the bellows into a freely-fluid mass of wax while the bellows is compressed, and the wax is then allowed to solidify.  The outside wax is shaped to conform to the inside of the vessel and is inserted in place and hermetically sealed.
