Patent CA-1165033-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE   A process is disclosed for curing a sand-furan resin mixture used m foundry practice to form cores and molds by the use or sulfur dioxide gas without forming sulfuric acid. Curing occurs when the furan resin, that is one containing a predominant amount of a furan moiety, is intermixed with a minor amount of a diisoproylbenzene monohydroperoxide (DIPBMHP) or diisopropylbenzene dihydroperoxide (DIPBDHP), or a mixture thereof. In addition to reacting with gaseous sulfur dioxide without forming sulfuric acid, these specific alkaryl hydroperoxides of which the monohydroperoxides have at least one alkyl ring substituent, have the peculiar characteristic of curing the resin in such a way that the DIPBMHP or DIPBDHP moiety becomes chemically bound in the cured resin. The result is a cured core or mold having a novel composition and superior physical properties compared to prior art cores and molds made with furan resins, in which the reaction with sulfur dioxide produces sulfuric acid. Cores end molds made by the instant process perform as well as, or better than those made with hexamethylene tetramine initiated thermally polymerized phenol-formaldehyde novolac resins, when used under comparable shell casting conditions.

Abstract: LOWER ALLERGENICITY AND LOWER THROMBOGENICITY FOODSTUFF AND PROCESS FOR PREPARING THE SAME          ABSTRACT OF THE DISCLOSURE     Foodstuffs  of  lower  allergenicity  and  lower thrombogenicity  are  prepared  by  removing a  water-soluble glycoprotein which occurs therein, the glyco-protein  being allergenic  and  thrombogenic.   In  a preferred processing sequence,  the foodstuff is sub-jected to extraction at a pH above about 4.5, and the resulting supernanent subjected to isoelectric extrac-tion by lowering the pH to between about 4.5  and about 4.0, whereby the glycoprotein precipitates.  The glycoprotein precipitate is removed and,  if desired, the supernatent,  with optional pH adjustment to its starting pH,  is  returned to the foodstuff residue. The  use  of glycoprotein in appropriate  dosages  to desensitize  atopic  individuals  who exhibit  hyper-sensitivity to common allergens is also described.

Abstract: VISCOUS SPRING DAMPER                     ABSTRACT A viscous spring damper including inner and outer mem-bers connected by an elastomeric shear spring and having a main or first fluid chamber disposed therebetween for communication with a second fluid chamber in the inner member through a res-tricted orifice.  The inner and outer members are relatively movable for stressing the shear spring and varying the volumes of the chambers while fluid is transferred therebetween through the restricted orifice.  An elastomeric bladder within the second fluid chamber is selectively chargeable with gas pressure for calibrating the damping characteristics, varying the initial spring rate or leveling a vehicle on which the damper is installed.  An elastomeric diaphragm is included in the main fluid chamber for providing a selectively chargeable diaphragm gas chamber.  Integrally formed wear ribs in the diaphragm minimize diaphragm abrasion effects at points of engagement between the diaphragm and the inner member and preclude an hydraulic lock between the diaphragm and the inner member.

Title: Arrangement for transmitting signals between two  relatively rotatable parts
Inventor: MARTENS GERHARD

Filed: 1983-02-10
Granted: 1987-03-03
Abstract: ABSTRACT:          The invention, useful in computer tomography, relates to an optical transmission arrangement for trans-mitting data between two relatively rotatable parts. The invention utilizes a hollow cylinder with a mirror-coated inner surface onto which the light is incident at the smallest possible grazing angle and is frequently reflected.  The light is coupled in and out through a coupling section in the hollow cylinder, which can be smaller as the angle is smaller at which the light is incident onto the inner surface.  In this case, there is obtained on the one hand a small pulse widening and on the other hand a comparatively low damping because the reflecting power at small angles of incidence is constantly comparatively high.

Therefore the light is propagated through the coil-like optical fiber in opposite directions, light from the coil-like optical fiber is synthesized and is incident on the light detector, and the speed of the rotation angle is detected by the output of the light detector.

Abstract: ABSTRACT: X-ray analysis apparatus.           In an X-ray analysis apparatus provided with a detector comprising photodiode-detection elements, it is possible to eliminate the dark current and the background current from the measurement signals due to the fact that elements in the signal reading device can be combined.          Due to the fact that also during the measurement at a stationary peak beside the signal amplitude also signal ratios can be obtained from combinations of detector elements, the correct position and amplitude of the peaks to be measured can be determined. The detector can also be provided with mutually separated detector elements which have such a surface area and configuration that the dark current can already be compensated thereby.

Abstract: PRODUCTION OF INSULATED ELECTRICAL CONDUCTORS            Abstract of the Disclosure:     In providing a dried insulation layer upon conductor, a covering fluid layer is initially provided by a process and apparatus in which the layer is formed from composite material comprising magnetically permeable particles homogeneously mixed with a fluid carrier.  The fluid layer is formed by passing the conductor through a reservoir of the material and then vertically through a die orifice.  The reservoir of fluid applies pressure at the die orifice and this pressure is adjustable to vary the rate at which the material passes through the orifice and thus varies the diameter.  This pressure is controllable by adjusting the height of the reservoir above a die orifice or by adjusting gas pressure acting downwardly upon the material.  The diameter of the layer is advantageously measured after it is dried and variation in measured diameter from that desired effects a change in pressure to alter the diameter towards that desired.  The diameter of the layer may, however, be measured with the layer in fluid form.     - i -
