Patent CA-2026841-A1 (CA)
IPC: D21F5/04
Filed: 1990-10-03
Abstract: A transfer apparatus is disclosed for transferring a tail of a web from a press roll to a dryer of a dryer section.  The apparatus includes a lead-in roll which is disposed adjacent to and spaced relative to the press roll for leading the tail of the web from the press roll towards the dryer.  A dryer felt extends around the lead-in roll and from the lead-in roll to the dryer such that the tail is supported by the felt from the lead-in roll to the dryer.          The felt and the dryer define therebetween a positive air pressure in-going nip.  A rotatable suction roll is disposed adjacent to and on the opposite side of the felt relative to the in-going nip such that in use of the apparatus, the suction roll generates a flow of air from the positive air pressure in-going nip through the felt such that when the tail of the web is being transferred from the press roll towards the dryer, the tendency for the positive air pressure in the vicinity of the in-going nip to prevent threading of the tail between the felt and the dryer is inhibited.

Abstract: IMPLANTABLE ELECTRODE AND METHOD FOR FABRICATION             ABSTRACT    An implantable electrode of the type in which an elongated wire coil forms the electrode surface.  The electrode coil is mounted around an insulative lead body and is stabilized on the lead body by means of a plastic filler between the individual turns of the electrode coil, extending radially outward to approximately one-third of the diameter of the electrode coil wire.  The filler is produced by stretching a portion of the lead body which normally displays an outer diameter greater than the inner diameter of the electrode coil, sliding the electrode coil over the lead body and inserting a mandrel into the lead body to urge the lead body into contact with the electrode coil.  This assembly is heated to encourage flow of the lead body into the spaces between the electrode coil to stabilize the coil on electrode body and to prevent fibrotic ingrowth around the electrode coil wire.

Title: Method for rapid magnet shimming
Inventor: GLOVER GARY H
IPC: G01R33/20
Filed: 1991-05-09
Abstract: ABSTRACT OF THE DISCLOSURE    Determination of the shimming fields for a polarizing NMR magnet is performed by acquiring two NMR images with evolution times differing by ?.  A pixel by pixel division of the images yields a third image whose phase is proportional to magnetic field inhomogeneity.  Several such inhomogeneity images are acquired within a cylindrical volume and the data of the images is fit according to a set of polynomials approximating the fields of the magnet shim coils.  The coefficient  of this fitting procedure are used to set the current level in the corresponding shim coils.  The interaction between correction fields is accommodated by an empirically derived correction matrix.  This procedure may be repeated to provide more accurate shimming.

Title: Suction cup for use in windows
Inventor: ADAMS WILLIAM E
IPC: F16B47/00
Filed: 1991-07-29
Abstract: An improved suction cup (110) made of a light transmissive material is provided having a head (112) and a cup portion (114) a concave interior surface adapted to contact a window and an exterior surface opposite said interior surface. A ridge (118) of material is provided along the outer portion of the exterior surface, so that, when the suction cup is in a sealing position, the ridge of material is generally parallel to the mounted surface.      In such an arrangement, light (130) passing through the ridge (118) of material continues in a straight path (134) and does not converge at a focal point (140).      Alternatively, surface deformations, such as grooves (218), circular ridges (216), dimples (318), and roughing, may be provided on the exterior surface of the suction cup. These surface deformations diffuse the light passing therethrough, preventing all of the light from converging at a focal point.

Abstract: Lactoneotrehalose, a novel saccharide shown by the formula O-.beta.-D-galactopyranosyl-(1~4)-O-.beta.-D-glucopyranosyl .alpha.-D-glucopyranoside, is prepared by allowing a saccharide-transferring enzyme to act on an aqueous solution containing lactose and amylaceous substance. Lactoneotrehalose is a non-reducing oligosaccharide, extremely stable, readily soluble in water, and substantially free of hygroscopicity, as well as having a satisfiable quality and moderate sweetness. These render lactoneotrehalose very useful in the preparations of orally-administrable products, cosmetics and pharmaceuticals.

Title: Electromagnetic relay with a contact spring mounted on an armature
Inventor: BIEHL WILFRIED
IPC: H01H3/00
Filed: 1991-11-07
Abstract: ABSTRACT OF THE DISCLOSURE A relay having a contact spring connected to an armature in which the contact spring is constricted near the free edge of the armature and is broadened into a T-shaped end to provide a double contact or bridge contact relay further includes supporting tabs applied to each of the transverse legs of the contact spring.          The supporting tabs are struck by the armature during armature motion directed toward opening of the contacts.  This transmits a jolt of force in the immediate proximity of the contact pieces during opening of the contact pieces in order to break any welding or adhesion of the contacts.  The relatively weak spring modulus for ensuring closing of the contacts is retained.

Title: Discharge excitation gas laser device
IPC: H01S3/0971
Filed: 1991-12-23
Abstract: In a discharge excitation gas laser device such as an excimer laser device provided with laser medium gas and a pair of electrodes opposite to each other in a gas-tight vessel, the laser medium gas is discharge-excited while inverting the polarity of a DC pulse voltage applied to the pair of electrodes opposite to each other for every pulse.  In this way distribution of atoms and ions constituting the laser medium gas in the discharge region including the neighborhood of the main electrodes is made uniform even at a high repetition rate oscilla-tion.  Thus it is possible to realize a discharge excitation gas laser device having a good stability of DC pulse discharge without increasing unnecessarily the flow speed of the laser medium gas and no lowering in the pulse energy owing to a high efficiency operation.
