Patent CA-2028887-A1 (CA)
IPC: H01G11/00
Filed: 1990-10-30
Abstract: A B S T R A C T      A gasket (4) or collecting electrodes (1) are used as members for separating the inside from the outside of an electrical double-layer capacitor and small holes (5) are provided therein through which the internal air is drawn.  Thus the  internal pressure becomes lower than the atmospheric pressure and the pressure difference is generated between the inside and the outside.     Due to this pressure difference, collecting electrodes (1) are pressed to solid polarizing electrodes (2).  Hence the resistance in the contacts between the collecting electrodes and the solid polarizing electrodes can be reduced.  Since the contact force is obtained by the pressure difference between the inside and the outside, the contact force is applied equally to every part of the contacts.  As a result, there is no contact where its contact resistance is not reduced.     Further,  there is no need of provision of any device for generating the contact force outside the electrical double-layer capacitor.

Title: Process for the preparation of 2,2'-oxydisuccinate
Inventor: GUTIERREZ EDDIE N
IPC: C07C51/347
Filed: 1990-11-30
Abstract: ABSTRACT            A process for the preparation of 2,2'-oxydisuccinate is disclosed which utilises a combination of a low reaction temperature and a minimum excess of calcium hydroxide to an organic reactant.  The use of a non reactive alkali metal salt of a strong or weak acid in the reaction mixture allows somewhat higher ratios of calcium hydroxide to reactant and somewhat higher temperatures. 2,2'-oxydisuccinate is produced in about 5 hours while gelation of the reaction mixture is substantially minimized.

Patent CA-2047372-A1 (CA)
IPC: H04Q11/04
Filed: 1991-07-18
Abstract: A data terminal interface for a terminal adapter and an attached computer provides complete flexibility and control of information in a communication environment for a user. Communications between the terminal adapter and a digital network may be provided in existing digital systems, such as either the Digital Communications Protocol or Integrated Services Digital Network system, for example. The data terminal interface facilitates the exchange of information between the terminal adapter and the computer via an asynchronous data module in the terminal adapter. Through the data terminal interface, the computer is able to directly control user interface ciruitry in the terminal adapter by responding to and sending unlimited information to this interface circuitry since conformance to a digital protocol is not required for message traffic between these two units. Also the data terminal interface permits all functions that a user is able to perform at the terminal adapter, such as going off-hook, pressing a button, etc., to be performed by the computer and provided to the network. Specific applications such as call screening, custom alerting and automatic call distribution are easily achieved through use of the data terminal interface.

Title: Fishing lure
Inventor: GAUNT JACK R
IPC: A01K85/14
Filed: 1991-07-18
Abstract: FISHING LURE Abstract of the Disclosure An improved fishing lure is disclosed which has an action which is more attractive to fish. The fishing lure of the invention has an elongated main body portion, tapered from a broad scooped nose end to a substantially pointed trailing end. The lure is secured to a fishing line by means of a plurality of holes through which the leader is woven from a location on top of the lure adjacent the nose, downwardly and rearwardly through a nose hole. The leader then passes upwardly through a central hole, remains on top of the lure to a position forward of the tail where it again passes through a hole in the body and terminates in a fish hook. The nose hole is wide enough in diameter to permit lateral freedom of movement of the line within the hole. The action can be varied for a given test line and a given trolling  speed by changing the position of  the central hole relative to the nose hole. The action can also be varied by varying the diameter of the nose hole.

Patent CA-2063333-A1 (CA)
Inventor: KIRA MASAKI
IPC: H04L1/22
Filed: 1992-03-18
Abstract: A fault occurring in a data frame is detected, thus avoiding incorrect data processing when the data frame is transmitted between a high-level unit and a low-level unit through a down transmission line or an up transmission lines which are used for connecting the high-level unit and one or more low-level units in series.  The data frame includes at least two fault monitor bits with an alternating bit pattern having different binary values.  Each low-level unit detects fault monitor bits with an alternating bit pattern having uniform binary values "HH" or "LL" as an alternating bit pattern breakdown fault occurrence.  When fault monitor bits of a data frame have a broken alternating bit pattern, being detected by a fault detecting means in the low-level unit as an alternating bit pattern breakdown fault occurrence, the low-level unit transmits a fault-occurrence notifying signal to the high-level unit through the up transmission line.  It is desirable to use a signal also conveying a broken alternating bit pattern of "HH" or "LL" as a fault-occurrence notifying signal.
