Title: Electrolytic removal of tin oxide or titanium nitride from a coater
Inventor: GORDON ROY G
IPC: C25F1/00
Filed: 1991-02-15
Abstract: A method for the removal of tin oxide (12) or titanium nitride (22) from a coater surface (10). The coater (10) is used to apply the tin oxide (12) or titanium  nitride (22) to a glass substrate.  When the build-up of tin oxide (12) or titanium nitride (22) on the surface (10) reaches a certain thickness, it must be removed.  The coated surface (10) is used as a cathode in an electrolyte (14) having an anode (16). The tin oxide (12) or titanium nitride (22) is electrochemically removed from the surface (10).
Patent CA-2077134-A1 (CA)
Inventor: NORIMATSU NORIKO
IPC: H04M1/724
Filed: 1992-08-28
Abstract: Appareil radiotéléphonique comprenant une unité d'indication du temps, une unité de mesure du temps, un contrôleur d'appels et une source d'alimentation auxiliaire. L'unité de mesure du temps mesure une période écoulée afin de détecter le moment où prend fin une période déterminée qui a été entrée au préalable dans l'unité d'indication du temps. Lorsque la mesure indique que la période est écoulée, le contrôleur d'appels limite le lancement d'appels. En outre, l'unité d'indication du temps et l'unité de mesure du temps sont alimentées par la source d'alimentation auxiliaire lorsque la source d'alimentation principale ne fonctionne pas, ce qui permet de mesurer le temps écoulé dans cette éventualité. Le lancement d'appels peut donc être limité après une période déterminée ou à partir d'un certain point dans le temps.

Title: Erythrocytes and thrombo-erythrocytes as target specific abents
Inventor: COLLER BARRY S
IPC: A61K35/18
Filed: 1991-11-12
Abstract: The present invention provides new compounds and methods for promoting platelet aggregation, and controlling bleeding. The present invention is based on the surprising discovery that erythrocytes conjugated to certain peptides and polypeptides containing an R-G-D (Arg-Gly-Asp) sequence (collectively termed herein "RGD  peptides") according to the invention, selectively bind to activated platelets but not to unactivated platelets. In recognition of the dual nature of the derivatized erythrocytes, they are termed herein "thrombo-erythrocytes". The thrombo-erythrocytes have no significant change in their rheological properties. In a preferred aspect, the thrombo-erythrocytes have the majority of RGD peptide cross-linked specifically to glycophorin A and glycophorin B on the surface of the erythrocyte. In the thrombo-erythrocytes of the invention, preferably, the N-terminal Arg of the R-G-D sequence should be spaced within 9-50 Angstroms, more preferably 10-40 Angstroms, and most preferably 11-25 Angstroms, from the erythrocyte protein to which the RGD peptide is conjugated. The invention is further directed to erythrocytes modified by replacement of their intracellular contents with a composition comprising a label or agent. Such modified erythrocytes are termed herein "carrier erythrocytes". The carrier erythrocytes have use in delivery of such labels or biologically active agents to specific tissues by conjugation to a targeting agent.

Filed: 1993-07-13
Abstract: The invention provides a new feed product, especially a fish feed product in the form of pellets or particles, with high fat content and superior physical properties.            The product is made immersing feed pellets in a first hot oil bath with a temperature higher than 100°C to secure drying of and simultaneous fat absorbtion.            This treatment is followed by a cooling in a warm oil bath kept at a temperature of 40 - 60°C. This completes the fat absorbtion and results in a dry product consisting of hard and smooth particles with high fat content, which are free flowing and do not agglomerate.

Title: Screened electromagnetic coil of restricted length having optimized field and method
Inventor: CHAPMAN BARRY L W
IPC: H01F7/20
Filed: 1992-08-24
Abstract: A primary gradient coil (4') and a screen coil (5') with the primary coil (4') are constructed to create a substantially null field adjacent to the gradient coil (4'). This coil (3) related to active electromagnetic field screen coils of restricted length and a method of optimizing the magnetic fields created by such coils over one proximate volume while maintaining a null field over a second proximate volume. A method is disclosed for generating the coils (4', 5') by considering the screen coil to be of infinite length, deriving a Fourier transform of the axial and other components of the field in which the transform is the sum of the per-missible harmonic modes on the coil surface in which a coefficient C n is derived representing the nth harmonic. A perfect screen coil is created and the number of terms C n selected using least squares optimization until there is no longer a signifi-cant change in the resulting field. Examples are given in for creating unscreened, screened, linear, axial and transverse gra-dient coils.
