Patent CA-2228570-A1 (CA)
Inventor: STEIN BERND
IPC: B21D22/16
Filed: 1996-09-04
Abstract: The invention concerns a method of producing pressure-rolled pipes (3) with a pressure mandrel (1) and one or a plurality of pressure rollers (2), the pipe (3) being disposed between the pressure mandrel (1) and the pressure rollers (2) and being plastically deformed by the force applied by the pressure rollers (2). In order to produce pipes with thickened wall sections at the ends, according to the invention, a first pressure mandrel (1a) with a stepped portion (4) at the tailstock end is used in a first operating step. The pressure rollers (2) commence their deforming action at the stepped portion (4) at the tailstock end, operating in the direction of the machine spindle.  The semi-finished pipe (3a) is then removed from the first pressure mandrel (1a). In a second operating step, at the end where a thickened wall section (5) has already been produced, the semi-finished pipe (3a) is clamped in a rotary chuck (6) (clamping mandrel or the like) mounted in the pressure roller machine. A second pressure mandrel (1b), which is secured at the tailstock end and has an outer diameter (d2) corresponding to the inner diameter of the thickened wall section, is inserted into the semi-finished pipe (3a). The pressure rollers (2) then shape the second thickened wall section from the tailstock end towards the machine spindle side.

Title: A floating skimmer
Inventor: CLARKE NEVILLE
IPC: E02B15/04
Filed: 1996-08-09
Abstract: A substantially clog-free skimmer (2, 40, 80) is described for location in a body of contaminated water, the skimmer is provided as the inlet for an oil/water separator which separator does not form part of the present invention. The skimmer (2, 40, 80) is designed to prevent the ingress of large sized rubbish or to substantially orientate relatively smaller sized rubbish such as leaves and the like so that the filtering system (61) of the skimmer (2, 40, 80) is not clogged during operation of the skimmer. The inlet of the skimmer has curved walls which orient the relatively smaller sized rubbish into an orientation which has the effect of not clogging the filter when the rubbish is collected in the filter. The correct orientation of the rubbish is achieved by having substantially curved walls associated with the inlet means or inlet ports. The skimmer may take a variety of forms and be fixedly attached to or at the base of the body of water or it may be free to float and be self-levelling by being provided with adjustable buoyancy tanks. If the skimmer is designed to be fixedly located at or towards the base of the body of water it is provided with a flexible membrane to allow the top portion of the skimmer to be self-levelling. The advantage of the skimmer is that it is substantially clog-free.

Abstract: A viscous heater includes a housing, a rotor, a silicone oil working as a viscous fluid, a radiator region, and circulating water working as a circulating fluid. The rotor is accommodated rotatably about a rotary axis in the housing, and includes a shearing member. The shearing member is formed so as to surround the rotary axis, and rotates along a rotary locus as the rotor rotates. The radiator region is defined in the housing, and includes a first radiator chamber and a second radiator chamber. The first and second radiator chambers are disposed so as to interpose the rotary locus of the shearing member therebetween. The viscous fluid is accommodated in the housing. The circulating fluid flows in the radiator region. The viscous fluid is sheared by the rotor to generate heat. The resulting heat is transferred to the circulating fluid to carry out heat exchange. Instead of the single and independent shearing member, the rotor can include a first shearing member and a second shearing member, and, instead of the first and second radiator chambers, the radiator region can include a single and independent radiator chamber. Not only the viscous heater exhibits superb heat-generating performance, but also it can be readily boarded on a vehicle and solve the problems associated with altering the general configuration (or the dimensions) of its rotor or its housing.

Abstract: A method for a fabricating a silica glass was provided. The method includes the steps of adding silica and a dispersant to a premix solution obtained by dissolving a monomer for acrylic resin and a cross-linking agent in a distilled water, and dispersing the mixed solution, and adjusting the pH of the mixture, to form a sol; removing air bubbles from the sol, and then aging the resultant sol;adding a polymerization initiator and a catalyst to the aging-treated sol, and adjusting the pH of the reaction mixture; pouring the reaction mixture into a mold, and then gelating the mixture; aging the obtained gel; demolding the aging-treated gel, and then drying the demolded gel; thermally-treating the dried gel to remove organic substances from the gel; and performing a hydroxy group elimination reaction and a sintering reaction on the gel from which organic substances have been removed. Therefore, a high purity silica glass tube, in which cracking after drying scarcely occurs and shrinking ratio is markedly low, can be obtained. Also, a large silica glass tube can be manufactured by this fabrication method.

Filed: 1998-01-29
Abstract: Integrin-immunoglobulin chimeric protein heterodimer complexes in which the .alpha.-chain and .beta.-chain of integrins have been associated in a stable state. These complexes are not only usable as drugs as such but also applicable to the assaying of binding of integrins to ligands and the detection of substances binding to integrins or those inhibiting binding of integrins to ligands. These comnplexes are also usable as diagnostic agents.  It has been found that integrins isolated in a stably associated structure would bind to extracellular matrixes under physiological conditions in the presence of plasma components, which indicates that integrins and, in its turn, extracellular matrix receptors might be usable as substitutes for platelets.

Title: Method and apparatus for implementing a wireline transmission connection
Inventor: TOMMISKA ANTTI
IPC: H04L27/26
Filed: 1997-05-09
Abstract: The invention concerns a method and apparatus for implementing a wireline transmission connection, especially a VDSL transmission connection. The transmission connection is implemented in electric form so that a separate frequency range is reserved for either transmission direction. To allow efficient filtration of radio-frequency interferences by using as simple an apparatus as possible, the frequency band of the transmission line (13) is divided into sub-bands limited by international radio amateur frequency bands (AB1...AB6) and the transmission connection is implemented in at least some of these sub-bands (a) by generating for each sub-band to be used a carrier wave with its own modulator and (b) by dividing the bits of the bit stream (DATA_IN) to be transmitted between the modulators of the transmission direction in question so that each carrier wave is modulated with some of these bits.
