Title: Synthetic peptide specificity of anti-myelin basic protein from multiple sclerosis cerebrospinal fluid
Inventor: WARREN KENNETH G
IPC: A61K38/00
Filed: 1991-10-22
Abstract: Human basic myelin protein (h-MBP) has a molecular weight of 18.5 KD and contains 170 amino acid residues. Synthetic peptides ranging in length from 8 to 25 residues and covering the entire length of the protein have been produced. Antibodies to h-MBP (anti-MBP) were found to be neutralized by the synthetic peptides, which span the h-MBP from about amino acid residue 61 to about ammo acid residue 106. The synthetic peptides, which cover both the amino (about residues 1 to 63) and carboxy (about residues 117 to 162) terminals of h-MBP did not neutralize purified anti-MBP. Accordingly, intrathecal administration of selected synthetic MBP peptides may be used as a treatment for Multiple Sclerosis by neutralizing anti-MBP.

Patent CA-2057629-A1 (CA)
Title: Slant plate type compressor with modified low capacity bias spring
Inventor: TERAUCHI KIYOSHI
IPC: F04B27/16
Filed: 1991-12-13
Abstract: A slant plate type compressor with a variable displacement mechanism is disclosed. The compressor includes a drive mechanism having a drive shaft rotatably supported in a compressor housing and a coupling mechanism for drivingly coupling the drive shaft to pistons such that rotary motion of the drive shaft is converted into recipro-cating motion of the pistons. The coupling mechanism includes a slant plate having an inclined surface. The slant angle changes in response to a change in pressure in the crank chamber and, thus, changes the capacity of the compressor. The drive shaft includes an inner end portion which has a diameter that is smaller than a diame-ter of the remainder of the drive shaft. A bias spring which has an outer diameter that is greater than a diameter of the remainder of the drive shaft is resiliently mounted on the inner end portion of the drive shaft between the slant plate and the cylinder block. The bias spring restores the slant plate back to its maximum slant angle when the slant angle is decreased below a predetermined angle without the bias spring interfering with the free pivoting motion of the slant plate between various inclination angles. Thereby, the impact forces which act on the internal component parts of the compressor when the com-pressor is started can be reduced, while at the same time the bias spring still can sufficiently urge the slant plate toward its maximum slant angle if the slant angle decreases below the predetermined slant angle.

Patent CA-2070644-A1 (CA)
Title: Apparatus and method for detecting faults in can end sealant depositing machine
Inventor: ALBERTSEN ALBERT
IPC: B21D51/26
Filed: 1990-12-04
Abstract: The present invention detects sealant deposit faults by detection of a quantity related to sealant flow within the valve chamber of the needle valve employed in the sealant depositing machine. A  proximity detector (120) indicates to an electronic controller (100) when a can end (30) is in position for depositing the sealant. The electronic controller preferably monitors the pressure within the valve chamber (26) during at least one predetermined interval of time during the open and close operation of the needle valve (27). Upon detection of a pressure abnormality during one of these predetermined intervals of time, the electronic controller generates a reject signal which enables the transport mechanism to remove that particular can end from the stream of can ends going to the next station and place it in a reject pile (38). The monitoring takes place during an initial opening period of the needle valve, and during a time when the sealant flow is relatively steady. The rate of flow of sealant into the controllable valve may also be measured directly or measured from the pressure difference measured on opposite sides of a flow restrictor (117).

Title: Photographic film processing
Inventor: SYKE DAVID A
IPC: G03D3/08
Filed: 1990-12-14
Abstract: In known film processing techniques, the amount by which a film is processed at each stage is determined chiefly by time. If a film is either over- or underexposed, it may be incorrectly processed producing unsatisfactory results. The present invention utilises an arrangement which measures changes in the infrared density of the film during processing to ensure that satisfactory results are produced. The arrangement comprises an infrared light emitting diode (22) and an infrared sensitive photodiode de-tector (26) which are both mounted in a support (20). Film (34) passes between the diode (22) and the detector (26) so that the amount of infrared radiation being transmitted through the film can be determined to provide a measure of the infrared density of the film at each stage during its processing.

Title: Disengager stripper containing dissipation plates for use in an fcc process
Inventor: CETINKAYA ISMAIL B
IPC: B01D45/12
Filed: 1992-10-20
Abstract: A method and apparatus for an FCC process uses dissipator plates at the outlet of a disengaging vessel to provide a quick separation of catalyst from product vapors and to prevent reentrainment of catalyst by stripping gas which is passed into the disengaging vessel. The process and apparatus use a riser for the conversion of an FCC feedstock and direct the effluent from the riser directly into a disengaging vessel to separate catalyst from the product vapors. Catalyst is directed downwardly out of the outlet of the disengaging vessel and through a series of dissipator plates that eliminate the tangential velocity that would be otherwise introduced by the vortex and would lead to reentrainment of catalyst. The dissipator plates are located in a stripping vessel positioned immediately below the disengaging vessel outlet to receive catalyst as it leaves the disengaging vessel.
