Title: Method for a reel change in a winding machine, and winding machine suitable for carrying out the method
Inventor: KAIPF WALTER
IPC: B65H19/29
Filed: 1996-05-24
Abstract: A method for change a reel in a paper winding machine which has at least one carrier roll. The paper web (3) is fed to the carrier roll (1). It wraps around a portion of the circumference of the carrier roll and is wound onto a reel (3.1). Shortly before reaching a desired reel diameter, the machine speed (V) is reduced to a creep speed (k). Subsequently, a weakened line (8) running transversely across is formed on the web and, upstream of the weakened line, an adhesive is applied, while keeping the relative speeds of the web and the covering surface of the carrier roll (1) equal or close to one another. After the web is adhered to the reel (3.1), the reel is expelled or ejected, as a result of which the web is severed at the weakened line (8).

Title: Method of linking data processing units, method of controlling an exchange, data processing unit, controller, and exchange
Inventor: DAASE DETLEF
IPC: G06F17/30
Filed: 1996-09-27
Abstract: The construction of large control systems requires the cooperation of data processing units (PU1, PU2) which operate with different operating systems (OS1,OS2). To that end the data processing units (PU1, PU2) access each other through a linkage of their data bases (DBMS1, DBMS2). By means of this linkage data from the other data processing unit (PU1, PU2) are made visible (processable) in accordance with the data model of its own respective data base (DBMS1, DBMS2). In this case the data bases (DBMS1, DBMS2) are linked by means of a replication mechanism which runs between their data base managers (DBM1, DBM2). This method of linking data processing units (PU1, PU2) is used to build the controller of an exchange from different data processing unitswhich cooperate to produce switching functions.

Patent CA-2193180-A1 (CA)
Title: Packet transferring device
Inventor: MURATA MAKOTO
IPC: H04L69/40
Filed: 1996-12-17
Abstract: When a data transferring operation ends in failure because a call was released in the midst of data transfer or the like, the data should be transferred again.  In this data re-transfer, it is desirable to reduce the time spent for data transfer regardless of the functions provided by a terminal side.  For this purpose, an order number is assigned to a packet containing data before it is sent.  This number is stored in a storage section.  Further, when a packet is confirmed as to its receipt by a transmission receiver, the order number of the packet is also stored.  For a resending operation of the same data, a transmitted packet and an untransmitted packet can be discriminated from each other through comparison between order numbers of a sent packet and a transmitted packet.  Based on the discrimination result, only untransmitted packets are subjected to a resending operation.
Patent CA-2194068-A1 (CA)
Inventor: SHIEH WEN
IPC: A23L5/20
Filed: 1995-06-23
Abstract: The immobilized enzyme for removal of residual cyclodextrins is either a combination of an alpha-amylase and a CGTase which has been immobilized or a fungal alpha-amylase which has been immobilized. In addition to either the fungal alpha-amylase or the CGTase and alpha-amylase, a debranching enzyme can also be employed. When using a debranched enzyme, the debranched enzyme is also immobilized. By using the immobilized enzyme, the step of inactivating the enzyme is eliminated and the contamination due to the inactivated enzyme is also eliminated.
Patent CA-2195284-A1 (CA)
Inventor: SCHAEFER RICHARD L
IPC: C21D9/00
Filed: 1997-01-16
Abstract: A plunger-style valve assembly for use in a launder system of a machine for casting parts made from molten aluminum or other metal comprises a valve body having a longitudinally-extending inlet passageway and a longitudinally-extending outlet passageway which communicate with one another through a valve port centered about a vertical axis.  A raised circular valve seat defines the valve port, and a vertically-movable valve element is aligned with the valve port and the valve seat.  The valve element has a resilient, heat-resistant sealing member secured to the lower end thereof.  The valve element can be raised or lowered so that the resilient sealing member moves into and out of engagement with the raised valve seat, thereby controlling the flow of molten aluminum from the valve body inlet passageway to the valve body outlet passageway through the valve port.

Patent CA-2197635-A1 (CA)
Title: Lavage instrument
Inventor: OLSON DANIEL H
IPC: H01M50/517
Filed: 1997-02-14
Abstract: A hand held lavage instrument 10 which generates a pulsatile fluid flow having amodulated waveform and provides selectable voltage increments for multiple fluid flow rates is disclosed. The fluid pump 60 used in instrument 10 generates a pulsatile fluid stream having a modulated back pressure waveform, and therefore, a modulated impact force waveform for a more tactually pleasing fluid stream for a lavage patient. Fluid pump 60 uses a multiple return worm shaft 80 and a reciprocating piston 70 to generate the pulsatile fluid stream. Worm shaft 80 has a continuous dual threaded groove 85 with a right handed threaded portion 87 and a left handed threaded portion 89. A follower 90 is used to translate the rotational movement of worm shaft 80 into reciprocal movement of piston 70 within the pump housing 62. The push-pull ratio of worm shaft 80 dictates the waveform modulation of the pulsatile fluid stream. A push-pull ratio of the worm shaft that is less than one produces waveform modulating with decreasing amplitude peaks during each fluid pulse. A push-pull ratio of a worm shaft that is greater than one produces a waveform modulation with constant amplitude peaks during each fluid pulse.

Title: Dual display system
Inventor: MOSCOVITCH JERRY
IPC: G06F1/16
Filed: 1997-04-28
Abstract: A display system includes a base, a pair of electronic displays, and an arm assembly that supports the displays from the base in vertical or horizontal registration. In one implementation, the arm assembly is a single telescopic member that rotates relative to the base and locks in vertical and horizontal orientations, the displays rotate relative to the member between corresponding extreme angular positions in which the operative angular orientation of the displays relative to horizontal is maintained, and the length of the member is adjusted to minimize separation of the displays. In another implementation, the arm assembly has separate arms rotating about vertically spaced axes and linked to minimize the separation of the displays automatically when vertically or horizontally registered. In a simple implementation, the arm assembly is a rigid arm that releasably attaches to the base only in vertical and horizontal orientations, the displays mounted releasably to the arm in pre-defined angular orientations that preserve their operative angular orientation, and one display can be connected to the arm at spaced apart position to adjust separation of the displays.

IPC: A61L27/00
Filed: 1997-06-26
Abstract: Bioabsorbable medical devices are prepared by oxidizing derivatives of cellulose, including methyl cellulose, carboxymethylcellulose, and cellulose acetate. The resulting material is formed into films, sponges and, in the case of oxidized methyl cellulose, gels, due to its unique property of being water soluble. The resulting devices are particularly useful in limiting surgical adhesions, and for hemostasis. Other uses include wound dressings and as a replacement for more expensive bioabsorbable gels such as hyaluronic acid.

Title: Electrical connections to encased electronic devices
Inventor: DIEMAN CHARLES A JR
IPC: F42D1/045
Filed: 1996-01-22
Abstract: A method and apparatus for operably connecting electronic devices through a closed container is achieved by securing one end of a laminate connector (28) to a first electronic device, e.g., a fireset circuit (22). Device (22) is placed in a housing (12) which defines a housing closure surface (16). A cover (14a), which defines a cover closure surface (18) dimensioned and configured to engage the housing closure surface (16), is placed on the housing (12) to define a housing-cover joint (20a), and the laminate connector (28) is disposed within the housing-cover joint (20a). The housing-cover joint (20a) is sealed with an adhesive and the second end of the laminate connector (28) is connected to a second electronic device. The thinness of the laminate connector allows it to pass through the housing-cover joint (20a) without significant adverse affect on the seal therein or on the pressure-bearing ability of the housing (12) or the cover (14a). In one application, the invention may be used to electrically connect an encased fireset to an external arming device.
