Title: Method of preparing catalyst for hydrogenation of hydrocarbon oil
Inventor: KAMO TETSURO
IPC: B01J27/188
Filed: 1991-10-15
Granted: 1997-06-03
Abstract: Disclosed  is  a  method  of  preparing  a  catalyst  for hydrogenation  of  a  hydrocarbon  oil,  in  which  an  aqueous solution containing a metal of the Group VI of the Periodic Table and a metal of the Group VIII of the same along with a hydroxycarboxylic  acid  and  optionally  phosphoric  acid  is added  to a carrier  substance consisting essentially of  at least one of an inorganic oxide and an inorganic hydrate, and the resulting blend is kneaded, shaped and thereafter dried at a temperature not higher than 200°C.   The catalyst has a high catalyst activity and is used for hydrogenation of a hydrocarbon  oil,  especially  satisfying  the  requirement  of reducing the sulfur content in a light oil.

Title: Organometallic containing mesophase pitches for spinning into pitch carbon fibers
Inventor: MCCONAGHY JAMES R JR
IPC: C10C3/10
Filed: 1991-11-07
Granted: 2002-01-15
Abstract: An improved process is disclosed for producing a unique metals-containing anisotropic pitch suitable for carbon fiber manufacture.   Soluble,  aromatic-orgarnometallic  compounds are added to a carbonaceous feedstock which is substantially free of mesophase pitch and the resulting composition is heat soaked to produce an isotropic pitch product containing mesogens  and soluble, aromatic-organometallic compounds.   Next,  the pitch product is solvent fractionated to separate mesogens which contain  metals  from  the  organometallic  compounds.     The metals-containing  mesogens are heated to a temperature sufficient to cause fusion to produce a metals-containing  mesophase pitch.       In another method, the carbonaceous feedstock is heat soaked to produce an isotropic pitch product containing mesogens and high molecular weight,  soluble,  aromatic-organometallic compounds are added to the mesogen containing isotropic pitch product prior to solvent fractionation. Metals-containing carbon fibers  produced  from the  mesophase  pitch  exhibit  enhanced stabilization, tensile strength and modulus properties.           Alternatively, the solvent fractionation or separation is conducted under supercritical extraction conditions to produce a metals-containing mesophase pitch.  Organometallic compounds may be added to the carbonaceous feedstock either prior to or after the heat soak step.

Title: Magneto-optic overwriting medium with rare earth-transition metal layers
Inventor: TOMOKO OHTSUKI
IPC: G11B11/10
Filed: 1992-01-10
Granted: 1996-09-17
Abstract: The object of the invention is to eliminate by using a multi-layered film initializing field in magneto-optical  recording capable  of direct overwriting,  and  to decrease the restrictions on the compositions of materials for media.   The medium consists  of  two  exchange-coupled RE-TM  amorphous  layers  (a memory  layer  and  a  reference layer) whose Curie temperatures are almost the same and only one of which is RE-rich without a compensation temperature, the two layers being laminated directly or indirectly with an intermediate layer that allows exchange-coupling to be interposed.  Before recording is carried out, the reference layer is magnetized in one direction.  Pulses of energy are emitted from the memory layer side so that the temperature of the reference layer remains below its Curie temperature when one of the bit data is recorded but reaches its Curie temperature when the other of the bit data is recorded.

Title: Free-species analyte assay
Inventor: SCHWARZBERG MOSHE
IPC: G01N33/74
Filed: 1992-05-26
Granted: 1999-12-28
Abstract: A method of determining free analyte level in a sample containing the analyte in free and bound portions is accomplished in sequential steps as follows. The sample is combined with a known first liquid volume containing soluble anti-analyte receptor in excess of the free analyte in the sample. The resultant mixture is incubated for a period of time sufficient to allow the binding reaction of the free analyte with the anti-analyte receptor to reach substantial completion to form a first incubation mixture. A known second liquid volume is added thereafter which contains soluble conjugate sufficient to reduce the sample proportion in the resultant mixture to no greater than 10% v/v, with the conjugate comprising a labeled analyte or labeled analog thereof, to allow the conjugate to bind with the anti-analyte receptor not bound in the first incubation mixture to form a second incubation mixture.       Thereafter, separation means is introduced to the second incubation mixture which comprises a solid phase coated with immobilized binder fox the anti-analyte receptor, which binder is in excess of the anti-analyte receptor to bind substantially with all of the anti-analyte receptor in the incubation mixture. The solid phase is then separated and washed from the mixture. The amount of conjugate that is bound to the solid phase is measured, and the free analyte concentration in the sample is determined.

Patent CA-2101714-C (CA)
Inventor: EDELEN STEPHEN ALTON
IPC: F16H61/32
Filed: 1993-07-30
Granted: 1999-08-24
Abstract: A position-feedback-control servomechanism for shifting the transmission of a vehicle has both an adaptive proportional-integral-differential controller to compensate for manufacturing variations, etc, and a voltage-compensation system that senses the battery voltage and prevents the gain of a servomechanism drive motor from varying significantly when the battery voltage changes. The motor is preferably a permanent-magnet type to whose terminals the battery voltage is switched on and off. The switching is done by electronic switches that are under the control of a pulse-width-modulated signal. The width of the pulses of the pulse-width-modulated signal is controlled by both a closed-loop position-error signal and a signal derived from an open-loop measurement of the battery voltage.

Granted: 1999-12-28
Abstract: A method is disclosed for separating a multicomponent gas mixture comprising at least three components into three product streams by means of adsorbent membrane zones operating in series. Each product is enriched in a different component based upon the relative strength of adsorption of each component on the adsorbent material. A non-permeate primary component product is obtained by the selective adsorption and permeation through the adsorbent membranes of secondary components which are more strongly adsorbed than the primary components in the gas mixture. Two or more permeate streams enriched in more the strongly adsorbed components are withdrawn from the membrane zones as individual secondary products, each of which contains a different component distribution determined by the relative strength of adsorption of the secondary components on the adsorbent material. Increased recovery and product purity are realized by the integration of pressure swing adsorption (PSA) and cryogenic separation systems with the adsorbent membrane zones. PSA reject gas is used as a membrane sweep gas to increase the permeation rates of secondary components.

Title: Process and device for the manufacture of mouldings and mouldings manufactured in accordance with that process

IPC: C08F216/06
Filed: 1994-07-15
Granted: 1999-01-19
Abstract: A measured amount of a material that is crosslinkable by impingement of a suitable form of energy, especially UV light (3), is introduced into a two-part mould (1) of which the cavity (15) determines the shape of a moulding (CL) to be produced. The two mould halves (11, 12) are held a small distance from one another so that a thin annular gap (16) is formed between them, which gap is in communication with the mould cavity (15) and through which gap excess material can escape. The crosslinking is triggered by impingement of the selected form of energy, the impingement being spatially restricted to the cavity (15) by suitable moulding (21) so that material disposed outside the mould cavity is not crosslinked.  In that manner mouldings are obtained that do not require subsequent mechanical processing, and the mould is reusable. The process is especially, but not, however, exclusively, suitable for the manufacture of contact lenses.
