Abstract: A process for the purification of epsilon-caprolactam (I) contg. basic substances (II) and other impurities comprises determination of the content of (II), heating (I) with 0.8-1.3 mole urea per 2 moles (II) and distilling the purified (I) under reduced pressure. Also claimed is (I) with a total impurity content of not more than 0.2 wt.% (pref. not more than 0.1 wt.%) (see below), obtd. by this process.Pref. (I) is heated with 0.9-1.1 moles urea (per 2 moles II) for 20-120 (pref. 30-60) mins. at 140-240 (pref. 180-210) deg.C. After fractional distn., the purified (I) can be redistilled in the presence of 0.1-0.5% alkali hydroxide; this reduces the impurity content to not more than 0.1 wt.%.

Title: Fire door with an espagnolette fastening
Inventor: HUSTADT ACHIM
IPC: E05C9/18
Filed: 1993-02-22
Abstract: The invention relates to a fire door with a wing (1) equipped with an espagnolette fastening (5, 6, 7, 8), the free espagnolette ends of which engage, in the locking position, into recesses of locking plates. It was found that door frames, when they consist of hollow aluminium profiles, experience very pronounced deformation under the effect of heat, this being caused by the high coefficient of thermal expansion of aluminium. Such usually arcuate deformations of the frame profiles entail the risk that the ends of the espagnolettes engaging into the locking plates will jump out of these and the door wing will therefore open prematurely and undesirably, with the result that the fireproofing effect is then cancelled. This problem is solved, according to the invention, in that the upper espagnolette (6) of the espagnolette fastening is coupled to a sleeve-shaped espagnolette attachment (9), in which an extendable pin (10) or bolt is guided displaceably, and in that a propellant expanding as a result of the effective heat is located inside the espagnolette attachment. By means of the sleeve-shaped espagnolette attachment, it is possible to guide an extension pin (10) displaceably therein and to accommodate a propellant (14) which increases its volume under the effect of warmth or heat. As a result of the expansion effect of the propellant when heat is generated, the extension pin (10) moves out of the sleeve, so [lacuna] Original abstract incomplete. <IMAGE>

Title: Method of changing pitch of note of wind instrument - has rotatable sleeve fitted with longitudinal holes in its wall running parallel to tube axis
Inventor: SAILER PETER
IPC: G10D9/04
Filed: 1993-03-05
Abstract: The hole (5) is fitted with a housing (3) in which a tube (4) is inserted which has additional note holes (6) in its wall. These additional note holes (6) run parallel to the tube axis. By rotating the tube (4) in the housing (3) these holes can be held open when held clear of the flanges (3a, 3b) or the holes can be closed by being positioned immediately over the flanges. This variation in the cross-sectional area of the air flow changes the pitch of the note. ADVANTAGE - The device is fitted wholly inside the instrument.

Title: Plate catalyst
Inventor: HUETTENHOFER KLAUS DIPL ING
IPC: B01J35/02
Filed: 1993-05-13
Abstract: To increase the contribution to the catalytic activity of a plate catalyst (18, 30) induced by flow guidance of a fluid medium, it is provided that the fluid medium is deflected at least partially from a principal flow direction (12) in at least one reaction compartment (6, 36) by a structure (8, 10, 32, 34) and arrangement of the plates (2, 4, 26, 28) and adjacent plates (2, 4, 26, 28) to each other. In this case a reaction compartment (6, 36) is delimited between each two directly adjacent catalyst plates (2, 4, 26, 28) and a holder apparatus (20) which is permeable to a fluid medium on an inlet and an outlet side, into which holder apparatus the plates (2, 4, 26, 28) are installed. By this means the vortexing of the fluid medium is considerably improved in comparison to plate catalysts with laminar throughflow, which also provides the possibility, at predetermined separation rates, of decreasing the volume of a plate catalyst according to the invention in comparison with the volume of a plate catalyst having laminar throughflow. The invention is applicable to all plate catalysts, in particular to catalysts for nitrogen oxide reduction by the SCR (selective catalytic reduction) process. <IMAGE>

Title: Apparatus and method for reducing the cross-section of elongate stock
Inventor: ECK WERNER DR
IPC: B21C1/02
Filed: 1993-06-04
Abstract: The present invention describes a new apparatus for reducing the cross-section of elongate stock and, in particular, of elongate stock containing metal, such as wire. The wire is passed through a first drawing device and driven at a first peripheral speed. The wire is then bent over a bending body and passed through a second drawing device, through which it is driven at a speed higher than the speed of the first drawing device. The wire is thus subjected to a simultaneous tensile and bending stress which leads to the desired reduction in cross-section of the wire.

Inventor: ERATH HERBERT
IPC: B23B41/06
Filed: 1993-07-10
Abstract: A drilling device for making undercut holes is proposed in which the drilling spindle (4) is pivotably mounted in a pivot bearing (13). A deflection element (19) which projects on one side on a rotary ring (11) tilts the drilling spindle (4) out of the position of the drilling centre axis (17). In order to obtain a wobbling movement, the rotary ring (11) is set in rotation by means of a drive device (2). The drill head (5) of a drilling tool connected to the drilling spindle (4) thereby performs a wobbling movement about the bearing centre point (18) of the pivot bearing (13). <IMAGE>

Title: Device for guiding a disc spring
Inventor: KNORR KARL
IPC: F16F1/32
Filed: 1993-07-16
Abstract: To guide disc springs (216, 217) on a guide stem (311) or in a guide bush (314), an elastic intermediate element (32, 34) which bridges the functionally necessary radial distance is inserted between the opposite metallic surfaces. The disc springs are thereby centred better relative to the guide element and between each another. The force transmission between the disc springs is more uniformly distributed and the out-of-balance is reduced. <IMAGE>

Title: Process for the production of a continuous, curved cover comprising a plurality of glass elements
Inventor: PAETZ WERNER DIPL ING
IPC: C03B33/07
Filed: 1993-07-23
Abstract: Two different processes are indicated for the production of a continuous, curved cover comprising a plurality of glass elements. In contrast to known processes, in which the glass elements are bent individually from single-sheet safety glass, where large production tolerances occur as a consequence of the subsequent thermal prestressing process, resulting in clearly visible impact points between the glass elements, in accordance with the invention first two glass sheets of approximately equal size, each taking up the entire area of the cover, are bent and cooled and subsequently cut into individual glass elements. The two glass sheets or pairs of glass sheets are laminated together before or after the cutting operation to give a laminated glass sheet or laminated glass sheet elements. Covers produced by this process are suitable, in particular, for an openable segmental arched roof for a vehicle.

Title: Device to supply screws to screwdriver
Inventor: BAUER JOERG R
IPC: B25B23/06
Filed: 1994-03-04
Abstract: The device has a pivot arm (12), which is moved relative to the housing (2). The arm has a grab with at least two jaws (18) at the end. The jaws enclose a groove to hold the shaft of a screw. The arm may be pivoted into a screw-in position, in which the head (55) of a screw is located directly in front of the driver journal (52). A control rod (30) is moved against the force of a spring (40). The free end of the rod is located next to the free end of a screw (53), which is held by the jaws. When the screw is screwed into a workpiece, the rod engages on the workpiece and is moved against the spring. This moves the jaws apart to release the screw, and frees the pivot arm to move out of the screw-in position.
