Patent CA-2133383-A1 (CA)
Inventor: IMAI KOJI
IPC: B01D35/147
Filed: 1994-09-30
Abstract: A filter includes a case, filtering material housed within the case, a cover which covers an open end of the case and is non-rotatable relative to the case, and an annular fastener clamping the cover to the case. The case includes a large-diameter portion at the open end of the case, the large-diameter portion including a convexity forming an engagement tab. The cover has a concavity into which the convexity is received to prevent the cover from rotating relative to the case. Moreover, the cover includes a screw thread on the outer periphery thereof. The annular fastener has a screw thread on the inner periphery thereof mated with the screw thread on the outer periphery of the cover. On the other hand, the annular fastener has a small-diameter portion engaged with the large-diameter portion of the case by which engagement and mating of the screw threads the annular fastener secures the cover to the case. By preventing relative rotation between the cover and the case, the filter can be easily installed by being screwed onto a threaded member of an automotive engine or the like.

Title: Method of forming a product integrally with a surface layer and the product
Inventor: HIRAKAWA HIROYUKI
IPC: B29L9/00
Filed: 1994-10-24
Abstract: ABSTRACT OF THE DISCLOSURE      This method of forming a product integrally with a surface layer material achieves to use a single forming die capable of vacuum forming and urethane forming and to require no preheating step before vacuum forming, by employing a surface layer material having a sufficient shapability at an urethane forming temperature and an urethane base which can endure residual stress caused by elogation of the surface layer material after vacuum forming.  Thus,  the product can be manufactured at a low cost. First, a surface layer material 2 which comprises a synthetic resin having a 30% modulus of 0.1 to 2.0 kg/cm is placed at a forming die (a first die 3) which is capable of vacuum forming and urethane forming, and vacuum formed into a predetermined shape. Second, a liquid urethane raw material which becomes an urethane base 1 having a maximum bending load of 30N or more after forming is introduced into a cavity of the forming die and solidified, thereby formed into the urethane base 1 integrally with the surface layer material 2.

Title: Apparatus and method for detecting coagulation/lysis of liquids
Inventor: EXNER THOMAS
IPC: A61B5/145
Filed: 1993-09-06
Abstract: A method and apparatus for testing the susceptability of a test sample to change between a liquid state and a coagulated state. A test sample (4) is applied to a porous sheet (5). The sample spreads through the porous sheet until it coagulate when the flow stops. By measuring a parameter indicative of the extent of spread or rate of spread of the sample e.g. the conductivity/elec-trical impedance (8) between thin electrodes (2, 3) on either side of the sheet (1), one may determine when coagulation and/or subsequent lysis of the sample occurs.

Inventor: LIN MARK WENJENQ
IPC: B61F5/16
Filed: 1995-06-30
Abstract: A novel combination of a rail car supported on a within the center bowl of its truck bolster comprises a unitary wear liner closely fitted within the center bowl so as to require no exterior protection from grit and debris carried in the environment outside that of the center plate assembly held in the bowl. The unitary wear liner is required to be formed from specified reaction injection molded (RIM) polymers which when moulded, are found to be free of microscopic voids >20µm and therefore, fully dense, unlike prior art polymeric wear liners for the center bowl. This property of being fully dense unexpectedly allows the liner to have specified physical properties which permit a railroad car truck equipped with the liners to operate with exceptional reliability, safety and for a long period of time.

Title: Multiphase staged passive reactor
Inventor: BODNARAS GEORGE
IPC: B01F5/06
Filed: 1994-06-03
Abstract: A multi-phase staged passive reactor (10) for promoting interphasic interaction of a first substance in a liquid phase with a second substance in a non-miscible liquid phase, a solid phase or a gaseous phase. The reactor comprises a plurality of stages (C, D and E) which define a flow path for the substances in different phases. Each stage is shaped to define a substantially curved flow path (12) having a centre of curvature located to one side of the flow path (12). Thus, for example, stages (D) and (E) have a respective centre of curvature (14, 16), on opposite sides of the flow path (12) whereby, in use, as the substances flow through the reactor (10) particles of the second substance are forced to migrate through the first substance, first in one direction and then in substantially the reverse direction due to an inertial field of changing direction thus generated. Due to the differences in the relative densities of the respective phases, differential inertial forces are exerted on each phase as the mixture flows along the general flow direction of flow path (12) the interphasic interaction thus produced includes both mechanical interaction due to for example, collisions and energy transfer, as well as chemical reactions due to, for example, oxidation and ion-exchange. There are no moving parts in the reactor (10) which is of relatively simple construction, and it is extremely efficient, achieving high reaction rates, high mass transfer rates and high mining rates.
