Inventor: TAMURA YASUO
IPC: B27N3/04
Filed: 1991-08-02
Abstract: A laminated material comprises a plurality of straight portions of vegetable stalks, each having an epidermis mainly of lignocellulose and a porous core. These straight portions of vegetable stalks are impregnated with a thermal hardener solution of a high-molecularisable liquid compound, resinified liquid, or mixture thereof. The stalks are then arranged in parallel to form a layer of a sheet-like material, the sheet-like materials are stacked on each other and pressed to cause the layers to come into close contact in a flat condition. It is possible to alternate the directions of vegetable stalks in adjacent sheet-like materials in order to increase the bending strength and other physical strength of the stacked multi-layer laminated material, such as a pillar-like laminated material. Such pillar-like material is made by using a female mold and male mold, pressed together, the vegetable stalks being placed in the female mold and hot-pressed. After the vegetable stalks are laminated, the resin compound in the thermal hardener solution can be set or hardened by heat treatment.

Title: Telecommunication switching system having adaptive routing switching nodes
Inventor: BALES BRUCE M
IPC: H04Q3/545
Filed: 1992-10-22
Abstract: A telecommunication switching system having switching nodes that perform adaptive routing by utilizing the fact that the switching nodes are arranged in a first and a second hierarchy. In addition, each switching node maintains routing information based on telephone and switching node numbers which identify the switching nodes. A destination switching node transfers its routing information back to an originating switching node which combines that routing information with its own in order to determine shorter call paths for subsequent call routing. The first hierarchy is a dialing plan hierarchy having groups of switching nodes at each dialing plan level. The second hierarchy is a switching node hierarchy based on the switching node number of each switching node with at least one switching node ofthe switching node hierarchy being at a different level in the dialing plan hierarchy. In order to route a call, a switching node first routes through levels of switching nodes in the dialing plan hierarchy until a second switching node is encounteredwhich can determine the identification of the destination switching node based on a dialed telephone number. The second switching node then routes the call through the node hierarchy using the identified node number until a path is determined to the destination switching node.

Patent CA-2101912-A1 (CA)
Title: Planing Boat Hull Form
Inventor: VAN DIEPEN PETER J
IPC: B63B1/40
Filed: 1993-08-04
Abstract: This invention relates to a marine vessel hull form, in particular to a high speed planing boat. It describes a new and distinctive shape of hull which, unlike other hull forms developed to date, features the shape which modifies the flow of water underneath and around it in such a manner that the waves behind the hull at speed are reduced to a minimum. This hydrodynamic effect results in reduced resistance and thus increased speed and / or reduced fuel consumption. Further, it will result in reduced wash behind the boat, an effect that will enable it to operate at full speed near shores where local regulations limit crafts' speed because of shore erosion caused by waves generated by boats and ships. The hull form described in this invention offer more stability than the traditional hulls do, due primarily to higher beam to length ratio and to the stern shape, which departs from the traditional "V", which is not particularly stable at speed or stationary.
