Title: Saccharide for supplementing energy to living body, and uses
Inventor: SHIBUYA TAKASHI
IPC: A61K31/70
Filed: 1991-11-12
Granted: 2002-07-23
Abstract: A composition for supplementing energy to a living body, which contains neotrehalose as effective ingredient, is disclosed. Neotrehalose is a disaccharide, therefore, when used in the composition, enables 2-fold higher energy supplement than in the case of using monosaccharide.      Neotrehalose has non-reducing properties, and this renders the composition stable for a relatively-long time period.

Granted: 1997-10-14
Abstract: In  a  method  for  preparing a starch solution, particles containing starch  are  mixed  with  cold  water and subjected  to  shear  forces,  such  that  any agglomerates formed are  broken  up,  and  each  individual  particle is wetted, whereupon  the mixture  is heated to at least about 60°C and maintained in the heated state until the viscosity maximum  of  the  solution has passed. The wetting and the heating take place before a viscosity  that is unacceptable from the point of view of handling has been reached.      A device for implementing the method, a starch solution prepared in accordance with the method, and the use of such a starch solution for making paper are also disclosed.

Filed: 1991-12-18
Granted: 1995-09-12
Abstract: A process is disclosed for fabricating lightweight honeycomb type structures out of material such as silicon carbide (SiC) and silicon (S).  The lightweight structure consists of a core to define the shape and size of the structure.  The core is coated with an appropriate deposit such as  SiC or Si  to give  the  lightweight  structure strength and stiffness and for bonding the lightweight structure to another surface.  The core is fabricated from extremely thin ribs of appropriately stiff and strong material  such  as  graphite.    First, a  graphite  core consisting of  an outer hexagonal  cell with six inner triangular cells is constructed from the graphite ribs. The graphite core may be placed on the back-up side of a SiC  faceplate  and then coated with SiC to produce  a monolithic structure without the use of any bonding agent. Cores and methods for the fabrication thereof in which the six inner triangular cells are further divided into a plurality of cells are also disclosed.

Title: Apparatus and method for applying ink to a substrate
Inventor: LEOPARDI EMMETT II
IPC: B41F31/02
Filed: 1991-10-28
Granted: 1995-08-29
Abstract: This invention relates to an anilox printing apparatus (20) for depositing ink onto a substrate (23) in a predetermined pat-tern. The apparatus (20) has a reservoir (22) provided with a weir (30) so that ink (24) may continuously overflow the top or end of the weir (30) and be removed from the reservoir (22) in a controlled fashion while maintaining a constant backpressure of ink (24) in the reservoir (22). This arragement provides the advantage that ink leakage and splashing caused by debris entering the nip associated with a doctor blade (26) held against the anilox roll (25) or by surface imperfections interfering with the seal formed by such a doctor blade (26) are eliminated. This also provides a printing apparatus (20) for complete coating of the peri-phery of the anilox roll (25) with ink (24) without a high pressure system.

Abstract: A striker pin device for providing a visual indication of an operated condition of an associated fuse, comprising a tubular housing 18 coaxially arranged within the fuse with an end of the housing in contact with an end of the fuse.  The tubular housing has a closure structure comprised of a one-piece integrally formed closure member having a projection protruding out of the housing and an opened end with a cavity. A piston with a central projection received in the opened end of the closure member forms a gas tight enclosure containing pyrotechnic material therein. An ignition element is attached to a brass pin which extends through the projection of the closure member and is connected to a tubular terminal or electrical conductor member which is attached to a high resistance pilot wire, which in turn is stretched through the fuse. The ignition element attached to the brass pin extends through the pyrotechnic material, between the contacting surfaces of the closure member and the piston, and between the contacting surfaces of the piston and tubular housing for electrical connection between the ignition element and the housing. Ignition of the pyrotechnic material drives the piston and thus a striker pin toward the opposite end of the housing to cause the striker pin to pierce the fuse cap thereby providing the visual indication of the operated condition of the fuse, the pyrotechnical material being ignited upon rupture of the low resistance fusible elements by the resulting flow of the shunt current through the electrically connected elements of the striker pin device.

Title: Method for fitting the roll mantle of a tubular roll intended for a paper machine or equivalent with glide bearings and a tubular roll that makes use of the method

Abstract: A method for providing a tubular roll mantle of a roll for a paper machine or equivalent with glide bearings and a roll including glide-bearings. The roll mantle is supported on a stationary roll axle by hydraulic glide-bearing members acting upon the roll mantle or upon the roll ends. The bearing members are loaded hydraulically by a pressure medium. The roll mantle is supported on the roll axle by at least one pair of glide-bearing members which acting radially and/or axially in opposite directions. When an outside force that shifts or attempts to shift the roll mantle in the direction transverse to the main loading direction and/or in the axial direction is applied to the roll mantle, the pressure in the glide-bearing member placed at the side of the higher loading is adjusted to a level higher than the pressure in the glide-bearing member acting in the opposite direction so that the outside forces are neutralized. In another embodiment, the roll mantle is permitted to be shifted over a certain distance in the main loading direction. When the roll mantle approaches its preset extreme position in this direction, the movement of the roll mantle is brake down, and finally the movement is stopped in its extreme position by the glide-bearing members.
