Abstract: AXISYMMETRIC CORRECTION COIL    SYSTEM FOR NMR MAGNETS           ABSTRACT OF THE DISCLOSURE    Even and odd pairs of axisymmetric correction coils are disposed on a cylindrical form at specified longitudinal positions.  The coil pairs are intended to provide correction fields for high strength magnets employed in NMR imaging applications.  The locations of the coils are chosen so that each coil pair generally contributes to all significant terms in the spherical harmonic expansion representation of the axial magnetic component in the volume within the central region of the cylindrical form except that certain coil pairs are selected and designed so as to fail to produce a particular one of these spherical harmonic component terms.

Abstract: 65175-66 ABSTRACT OF THE DISCLOSURE In the receiver for bandspread signals, the pseudo-random code (PRC) stored in the receiver is synchronized with the code of the received and modulated signal, and the modulation is recovered. The means provided for this purpose include control loops. In the receiver, the modulated carrier signal, after being converted to the IF value, is digitized and then multiplied by the stored PRC. The signal produced in this manner is sampled at twice the rate at which the PRC is read out of the memory. The sampled signal is provided to a counter, and I and Q signals are formed from the counter output values. The controlled variables required for synchronization and demodulation are determined from these I and Q signals in control loops.

Abstract: ABSTRACT OF THE DISCLOSURE:           In a method for producing chip- or fibre-board, a fluid concentrate is added to at least one component of the raw materials used to produce the said chip- and/or fibre-board.  These raw materials comprise a cellulosic material (eg wood chips) and a bonding agent preferably in a glue bath.  The fluid concentrate is preferably added to the organo-chemical bonding agents,  or to the glue-bath containing  the bonding agent.   The  fluid  concentrate consists of specific parts by weight of boric acid and a water-soluble compound,  or a water-soluble mixture of compounds, containing at least one alcohol, preferably a primary alcohol,  and at least one water-soluble aliphatic amine or polyamine and/or an alkoxyamine or an alkanolamine, as well as water if necessary.  These ingredients  are mixed with each other and are then pressed, using a specified pressing power at a specified temperature.   The fluid concentrate is thus used as an additive to organo-chemical bonding agents, or to a glue-bath containing such a bonding agent for the production of chip- or fibre-board.  Use of the stated amounts of the fluid concentrate significantly improves the flame-retarding properties of the boards thus made.

Abstract: ABSTRACT           A method and apparatus for use in form, fill, and seal machines wherein a polyfoil material is compressed between two jaws, one jaw having a secondary induction coil which passes through an electromagnetic field and induces a current in the metallic layer of the polyfoil, to heat and then seal the polyfoil.  In a preferred embodiment, a plurality of nonconductive sealing jaws, each contain-ing a secondary induction coil, are mounted on an endless carrying means and a plurality of opposing corresponding rigid pressure jaws are also mounted on an endless carrying means and are arranged so that, as the carrying means advance continuously, each sealing jaw and corresponding pressure jaw con-tact and compress together facing thermoplastic layers of a polyfoil material and each secondary coil passes through an electromagnetic field to induce a current in the secondary induction coil which in turn induces a current in the area of the metallic foil layer proximate to the secondary induction coil to heat the foil and soften the adjacent thermoplastic materials which, because they are pressed together, will fuse and harden upon cooling.  In continuous transverse sealing of a filled polyfoil tube, the pressure jaws may include a knife to sever the seals, the polyfoil tube may be preformed before it is sealed, and the sealing and pressure jaws may have an alignment means to facilitate severing and sealing. The secondary induction coil is preferably an elon-gated twin loop coil folded so that one loop is fully subjected to the electromagnetic field and the second loop induces a current in the polyfoil tube.

Abstract: ABSTRACT      A bicycle sprocket drive which utilizes a crank having a number of splines and a sprocket having mating indentations or slots in its face.  The splines and the mating radial slots have tapered driving faces.  By cold forming the tapered slots into the front face of the sprocket, as by a stamping process, the removal of material from the sprocket is avoided.  The resulting back faces of the sprocket slots, because they are displaced from the remainder of the sprocket, serve to provide the desired alignment of the drive sprocket with the rear or driven sprocket of the bicycle.

Abstract: IMPROVED MANHOLE RISER HAVING INTEGRAL FLEXIBLE WATERLOCK FOR MANHOLE COVERS AND HAVING A WATER      TIGHT SEAL FOR SEALED MANHOLE COVERS           ABSTRACT OF THE DISCLOSURE      A hollow, flexible, bendable, cylindrical-shaped, hat-like sleeve is water-tightly joined with the upper end of the riser section of a manhole structure. The free end of the sleeve is trimmed so that its upper edge fits beneath the shoulder of the frame supporting the manhole cover to prevent subsurface water from entering into the manhole interior through the regions between the manhole cover supporting frame and the top of the riser section, which is usually fitted with adjustment rings to bring the manhole cover frame up to grade. The sleeve is easily cut to any height to accommodate either a greater or lesser number of height adjustment rings. The sleeve flange is cast into the riser section. The sleeve may be folded into itself to significantly lower its profile to expedite handling, transportation and assembly. A plastic clamping band may be placed into the interior of the sleeve to water-tightly join the upper end of the sleeve to the manhole cover support frame.

Abstract: An improved fastening element for a nipple 5 provided with a bead 6 in a comforter consists of a tapering part 1 with end flange 2, which part may be provided with a borehole 9 and can snap into a fixing space 8 bounded by a protective disc 4 and a ring flange 3 making a single piece with the protective disc or arranged on the protective disc with inwardly directed shoulder 7, which tapering piece 1 can move in the fixing space 8, and which tapering piece 1 locks the nipple 5 between itself and the protective disc. This avoids the nipple 5 being always clamped against the edge of an opening 10 in the protective disc, as is the case with the known fastening elements, since the piece 1 is clamped on top by the shoulder 7. This avoids constant rubbing against the rubber of the nipple with the risk of total rubbing off of the rubber. <IMAGE>

Abstract: The linear feed device is suitable for extremely slow feed rates or extremely small feed steps. It works with two motors (M1, M2) which drive a nut (16) and a screw spindle (2) via an intermediate drive (12-15; 22-25). The intermediate drives have slightly different transmission ratios, e.g., 1:0.340909 and 1:0.3414634. With a thread pitch of 2 mm of the spindle, this results, with the same direction of rotation of the motors, in about 0.0013 mm advance per revolution of the motor shafts. With the help of step motors, therefore, extremely small advance steps can be achieved.

Date Apr. 26, 1984.A method of transferring a service channel over a fibre optic system line is proposed. The system line normally transmits regular data signals with a specific highfrequency (34% Mbits), which are coded according to a certain code. The power spectrum of the code is heavily suppressed for lowfrequencies. In accordance with the invention, the space at f=O is utilized to transmit a service channel with a low bandwidth. The service channel signals are frequency modulated and the frequency modulated signal is caused to pulse width modulate pulses forming the regular data signal. The pulse width modulation is done in two different ways, depending on whether the data signal is an RZ-coded bit flow or an NRZ-coded bit flow.
