Abstract: Method for joining by crosslinking plastic components comprising a resistor enabling them to be heated electrically to the appropriate temperature for joining. According to the invention the crosslinking agent is introduced onto the components whose temperature is adjusted for a sufficient period to allow the agent to diffuse without crosslinking and the temperature of these components is then raised between approximately 150 and 350 DEG C for a period of time longer than the half-life of the agent, so as to induce the crosslinking of the plastic, thus ensuring the leakproof joining of the components. The invention applies especially to the production of gas distribution networks.

Abstract: Electrodialysis is used to separate at least one species of a first group of elements present in ionized form from at least one species of a second group of elements present in nonionized form in water-containing solutions, provided that the pH of the solutions and the oxidation state of species of the second group have the appropriate values.  If necessary, either the pH, the oxidation state or both are adjusted in the solution fed to the electrodialysis unit such that species of the first group are present in ionized form and species of the second group are present in a nonionized form.  The method is applicable to a large number of solutions from metallurgical and chemical processes.      Species of the first group include at least one element of groups IA, except Fr, IB, IIA, IIB, IIIA except B, IIIB, IVB, VIIB and VIII except Os of the periodic table; the elements V, Cr, Sn, Pb and Bi: and acids of N, S, F, Cl, Br and I.  Species of the second group comprise acids containing at least one element including B, C, Si, Ge, P, As, Sb, Se,   Te and F.  Electrodialysis is carried out in one of more stages at 10-500 A/m2 and 0-60C while minimizing water splitting, and using alternating cationic and anionic permselective membranes forming alternating concentrate and diluate cells between an anode and a cathode.  The ionized species migrate through the membranes from the diluate to the concentrate cells and the nonionized species remain in the diluate cells.  Solution concentrated in ionic species is withdrawn from the concentrate cells, and solution containing the nonionized species is withdrawn from the diluate cells.  The electrode compartments are rinsed with appropriate rinse solutions.

Granted: 1992-03-31
Abstract: ABSTRACT OF THE DISCLOSURE:         A conveyor is disclosed which serves for trans-porting bales of hay or the like material in a curve. It is made up of a frame, having a bale-receiving and a bale-discharging end; of an endless link  chain extending between the frame ends and following the conveyor curve, and of an upright shoulder plate, mounted on the frame between its ends.  This plate follows the chain on the chain side facing inwardly of the curve and is provided, on one face, with a plastic chain support for carrying the chain.  This chain support is formed with a pair of parallel grooves longitudinally extending between the frame ends.  Each groove has an opening on the side of the support facing away from the shoulder plate.  These grooves are configured and spaced from one another for slidably supporting the chain strands between the frame ends.  The strands are fitted into the grooves and protrude partly out through their openings.  Finally, bale-driving spikes are fixed to the chain, outwardly of the grooves, to carry the bales from the receiving to the discharging ends of the conveyor.

Title: Distance-controlled tunneling transducer and direct access storage unit employing the transducer
Inventor: POHL WOLFGANG D
IPC: G11B21/21
Filed: 1989-09-27
Granted: 1994-10-25
Abstract: ABSTRACT This distance-controlled tunneling transducer (1) comprises a plurality of sharply pointed tips (2) arranged in an array at tunneling distance from the electrically conductive surface (6) of a storage medium (7). Each tip (2) is attached to a cantilever beam (3) permitting the distance between each tip (2) and the surface (6) to be individually pre-adjusted by electrostatic means (8, 9). Arranged in juxtaposition with each cantilever beam (3) is a simple active control circuit (12, 13, 16) for adjusting the tip/surface distance during operation of the storage unit thus preventing crashes of the associated tip (2) into possible asperities on the surface (6) of the recording medium (7). Each control circuit (12, 13, 16) is designed such that its operating voltage, at thesame time, serves to pre-adjust its associated cantilever beam (3) and to maintain the gap width essentially constant.

Inventor: STOJANOVIC GEORGE
IPC: A61B5/03
Filed: 1989-09-29
Granted: 1995-07-18
Abstract: Apparatus for selectively aspirating and draining a body cavity includes a cylindrical housing having a flanged closure at one end from which extends a cannula within a flexible catheter for placement into the cavity.  An open discharge port at the other end of the housing is attachable to a suction tube.  A pair of cylindrical check valves are coaxially positioned within the housing together with the cannula which includes a sharpened end that retractably extends through the catheter and a self-sealing elastomeric closure plug in each valve.  The opposite end of the cannula terminates in one end of a receiver mounted in the housing, the other end being closed with a removable plug and adapted for attachment to an aspirating syringe.  A side port of the receiver communicates with a self-supporting balloon that is dimensionally responsive to air pressure within the cavity and therefore functions as a pressure indicator.  Withdrawal of the cannula from the cavity and check valves permits drainage of the cavity through the catheter, check valves and suction tube, with the catheter remaining in place unless separately withdrawn.

Abstract: Extrusion of a mixture of vegetable bits with a binder, particularly wood chips with a weather-resistant binder, involves precompressing in a compression chamber of an extrusion press the mixture by a compression stroke transverse to the extrusion axis, the compression stroke being delivered by at least one precompression piston. Prior to the precompression elongated bits of the mixture are acted on by an orienting influence so that the elongated bits are deposited substantially parallel to the extrusion axis. The outer layers of the mixture are compressed with a reduced precompression ratio so that the bits oriented prior to precompression remain fixed in position during the subsequent extrusion stroke. Preferably the elongated bits in the mixture are oriented by free fall of the mixture through a plurality of upright, thin-walled bars of approximately equal height positioned above the compression chamber during filling of the extrusion apparatus by a mechanical hopper moving to and fro over the bars continuously.
