Abstract: The invention concerns a roll (1) adjustable in zones. The roll comprises a stationary roll axle (3), around which the roll mantle (2) is arranged revolving. The deflection of the roll mantle is regulated by means of glide shoes (5) supported on the roll axle (3) and acting upon the inner face (4) of the roll mantle (2) in the direction of pressing of the roll (1), said glide shoes being loaded by means of a loading produced by pressure fluid by means of pistons (8) placed in cylinder bores in the central axle (3) underneath the glide shoes (5). Adjoining glide shoes (5) in the roll are, at least in pairs, sealed (6) relative each other, being displaceable in the radial direction of the roll (1), so that flow of fluid between the glide shoes (5) and the inner face (4) of the roll mantle (2) is substantially prevented over the lateral ridges on the glide shoes (5) sealed (6) relative each other. Hereby, the power requirement of the rotation of the roll can be made lower.

Title: Blood perfusion system and tube means used therein
Inventor: NOBUYOSHI MASAKIYO
IPC: A61M25/08
Filed: 1989-10-11
Granted: 1995-11-14
Abstract: In a blood perfusion system comprising a dilation catheter defining a lumen and including a dilating member at the leading end, and a sheath defining a bore through which the dilation catheter is inserted to define a blood intake gap between the outer surface of the dilation catheter and the sheath bore and including a transverse bore branched from the sheath bore, a tube is connected at one end to the transverse bore and at another end to the lumen of the dilation catheter at a trailing end.  When the sheath having the dilation catheter inserted therein is set in a blood vessel, a pump in the tube operates to take blood into the blood intake gap in the sheath, pass through the tube and the dilation catheter lumen, and feed back to the periphery of a lesion through the open leading end of the dilation catheter.  The patient's own fresh blood can be injected without the need for a further cutdown or puncture for blood intake.
Patent CA-2002378-C (CA)
Inventor: MCEWEN STEPHEN N
IPC: B01D21/00
Filed: 1989-11-07
Granted: 1996-11-26
Abstract: The filtration system includes a tank and a pump for suctioning clean filtrate from the tank and pumping filtrate into a discharge manifold.  The pump includes a suction inlet port,  an impeller and a discharge head.  A suction connection to the filtrate is provided in the side wall of the tank and a fixed discharge housing includes an annular enclosure which cooperates, when the pump is installed, with the pump discharge head to connect the pump discharge to the manifold.  To install the pump, the inlet suction port and  impeller  are  passed  horizontally  through  the annular enclosure for sealing connection with the tank receptor ring.   The discharge head mates with the annular enclosure whereby filtrate may be pumped from the tank through the discharge head to the manifold. To remove the pump,  the pump is displaced in the opposite horizontal direction by withdrawing the head from the annular housing and the impeller and suction inlet port through the annular housing.           Alternatively, the pump can be pre-mounted in a holder or container, with the discharge head pre-aligned with the annular enclosure, where the inlet suction port does not require sealing connection with a receptor ring.

Title: Continuity logging using differenced signal detection
Inventor: KROHN CHRISTINE ELIZABETH
IPC: G01V1/42
Filed: 1990-06-06
Granted: 1999-12-07
Abstract: A method of determining the continuity of a lithographic layer located between two vertical boreholes is disclosed. A seismic source is lowered in the first borehole while simultaneously a receiver pair, preferably a pair of "vertical" geophones spaced apart by about two feet, are lowered in the second borehole to develop a "differenced signal". The recording of high amplitude signals within a layer is an indication of a continuous, low velocity layer.      The middle of a layer can also be discovered using a single vertical receiver and finding the place of phase reversal.

Title: Ice cube and crushed ice dispenser
Inventor: GOETZ GLENN E
IPC: F25C5/04
Filed: 1990-12-17
Granted: 2001-03-20
Abstract: A selective ice cube and crushed ice dispenser having a crusher section including a crusher arm mounted to a horizontal shaft axially rotatable in either direction, and a stationary crusher arm mounted to one side of the shaft. When the shaft is driven in one direction, ice pieces fed to the crusher section are caught and crushed between the rotating and stationary crusher arms. However, when the shaft is driven in the opposite direction, the ice pieces escape down the side of the shaft opposite the stationary crusher arms thereby avoiding being crushed. The ice piece feed within the ice piece receptacle is also rotatably driven by the shaft and is operable to feed ice pieces to the crusher section regardless of which direction the shaft is being driven.

Title: Information processing apparatus and method
Inventor: HIRAYAMA TOMOSHI
IPC: G06K9/62
Filed: 1991-03-26
Granted: 2000-07-25
Abstract: An information processing apparatus with a hand-writing character recognition function includes an input device having a pen and tablet for inputting a user's hand-writing character information, and a selecting device for selecting a desired block type character on the basis of the hand-writing character information, selection of the block type character (corresponding to the hand-writing character information) being effected by the hand-writing character recognition function. A detecting device detects a similarity condition between first and second hand-written characters initially input by the user on the input device, and hand-writing character information for the user based on the first and second hand-written character is registered if the similarity condition was detected. Subsequently, if the user inputs a hand-written character similar to the user's registered hand-writing character information, the input hand-written character is translated into the desired block type character.

Typically, the transparent screen is mounted in the shroud and is removable therewith.     Filtration devices are formed or mounted in the shroud so as to, be disposed adjacent to the fans when the shroud is placed over the structure. A suitable power supply, such as a battery pack or the like, is used to selectively power the fans. It is anticipated that at least the shroud (and the components mounted thereto) will be disposable.
