Patent CA-2304332-A1 (CA)
Inventor: GUILLAUME DIDIER
IPC: E06B5/16
Filed: 2000-04-07
Abstract: There is created in a modular shaft door system a fireproof lift shaft door (1) predominantly by flange-mounting, to standard shaft door panels, of flat insulating material housings (30) filled with high-efficiency, novel insulating material layers (31). These insulating material housings are so constructed that they have throughflow chicanes in the region of the closing edge and form, in the closed state, additional labyrinth-like obstacles (36) against the passage of flame and gas in co-operation with the door frame. An overall flat mode of construction of the shaft door (1) enables, with minimal loss of usable shaft cross-sectional area, the doors to be mounted in rational manner by simple flange-mounting to the shaft wall (3). A wide door frame may compensate for large constructional tolerances, and appropriate fastening elements allow the alignment of the shaft door in all directions and in a range corresponding to the large constructional tolerances.
Patent CA-2307968-A1 (CA)
Inventor: ANGLE RICHARD
IPC: H04L12/56
Filed: 2000-05-09
Abstract: A memory management technique for maintaining packet order in a packet processing system involves maintaining a START indicator and a VALID indicator for each memory block in a packet memory. Packets are written in a number of successive memory blocks, and the START indicator corresponding to the first memory block of the number of successive memory blocks is set to indicate that the packet is available for processing.  The packets are processed by a packet processor. When the packet processor completes the processing of a particular packet, the VALID indicator corresponding to the first memory block associated with that packet is set to indicate that the packet is ready to be forwarded.  The packet may become ready to be forwarded out of order. However, the packets are forwarded in first-in-first-out order by processing the packets in first-in-first-out order and only forwarding a particular packet if the VALID indicator corresponding to the first memory block associated with that packet is set to indicate that the packet is ready to be forwarded.  Thus, a packet is not forwarded unless and until all previous packets have been forwarded, even if the packet is ready to be forwarded before one or more previous packets.

Title: Ferroelectric liquid crystal devices with twisted structure
Inventor: LIU JIAN-YU
IPC: C09K19/02
Filed: 1998-11-25
Abstract: A hybrid analog/binary electro-optic modulator using a twisted ferroelectric liquid crystal structure is provided. Ferroelectric liquid crystals with a tilt angle of between about 20~ and about 25~, preferably about 22.5~ are used. Rubbing directions for the two cell walls (relative to one another) can be varied from about 45~ to about 90~. In one embodiment, a weak buffing force is used resulting in a relatively weak anchoring energy at the surface, aligning the liquid crystal molecules without locking the molecules into the buffing directions and a high pre-tilt structure for the molecules close to the surface boundaries. In one embodiment, strong buffing is used with buffing directions offset about 45~. Use of this invention provides relatively fast response time, low required driving voltage, high contrast, and/or the ability to achieve both analog and binary operations.

Title: Arrangement for executing program code with reduced memory requirements
Inventor: SOEPENBERG GERRIT H
IPC: G06F9/445
Filed: 1999-12-20
Abstract: A Java virtual machine (2), comprises an execution engine for executing Java byte code and a memory management system (14). The memory management system (14) performs garbage collection to remove objects that are not reachable from the current state of the Java program. In the prior art memory management system objects of the representing a class definition are only removed from memory if the classloader object which has loaded the class object is not reachable. According to the present invention the memory management system (14) is arranged for removing classes which do not have any instantiated objects which can be reached in the present state of the program even if the classloader is still reachable. This results in a substantial saving of memory. Preferably the objects representing a class definition have a method which can signal to it that the definition can be deleted from memory if it has no instantiated objects anymore.

Abstract: A cross sealer for a bag making machine includes a frame with an upper seal bar unit and a lower seal bar unit in aligned opposed relation. One is movable seal bar unit which includes a rigid support beam of a lightweight construction and a light weight seal bar connected to the beam by a plurality of adjustable stud units for adjusting the position of the seal bar. A rotating shaft spans the cross sealer and is connected by a plurality of eccentric linkages to the beam between side plates of the frame. The linkages support the beam and seal bar and transfers the sealing force onto the beam and bar for moving the bar into sealing engagement across the width of the web. The opposed seal bar unit is similarly constructed with a beam and a seal bar with the units interconnected by adjustable stud connectors. The second seal bar unit is mounted as a substantially stationary unit and includes a plurality of substantially fixed connectors supporting of the fixed beam along a plurality of locations to form a relatively rigid beam support. Alternate fixed beam supports include air cylinders to provide a cushion support for the seal unit. The connecting studs in the opposed seal units are offset to allow the respective beams to deflect and conform more fully to each other and to form an effective smooth and constant seal across the web. The eccentric shaft is shown driven by a servo motor and alternatively by a fluid cylinder and linkage drive unit. The drive system includes a controlled drive and linkage to provide for various seal dwell periods and configurations.
