Patent CA-2126610-A1 (CA)
Title: Digital data-dependant ac impedance termination of telephone line
Inventor: PARKER GEOFFREY H JR
IPC: H04M1/24
Filed: 1994-06-23
Abstract: The potential impedance mismatch of digital terminal equipment and a line test unit conforming with the Bellcore standard of terminating the line with a 600 - 900 ohm impedance during data reception includes a controllably disabled AC impedance, operable to normally bridge the tip and ring leads of the telephone circuit under test with the required (600-900 ohm) impedance during data reception, under direct control by the craftsman's keypad or software control resident in the test set's microcontroller, to selectively remove the AC matching impedance that would otherwise bridge the line. The AC impedance is comprised of a D.C. blocking capacitor and a resistor coupled in series with a controllable solid state relay which is normally rendered conductive during data reception to bridge the tip and ring leads. By direct manual control from the craftsman's keypad, or software control resident in the test set's microcontroller, the control signal supplied by the microcontroller to the solid state relay may be removed, so as to selectively decouple the AC matching impedance that would otherwise bridge tip and ring leads of the telephone line during data reception.

Patent CA-2133229-A1 (CA)
Inventor: RAMSAY THOMAS W
IPC: F04B35/04
Filed: 1994-09-29
Abstract: The present invention relates to an Electro-Magnetic Induction-Driven Piston compressor.          Various devices have been previously proposed for compressing gases or air, reciprocation, Screw and Centrifugal compressors. In practice however, these devices have proven weaknesses either at the point of the gas packing gland, or the sealing devices where the shaft enters the unit. The gas packing or seals try to prevent the high pressure and in certain cases dangerous gases from leaking into the atmosphere, causing premature shutdown of tile unit. Therefore, it is the object of the present invention to prevent one or more of the above mentioned weaknesses and disadvantages.

Patent CA-2166087-A1 (CA)
Inventor: CYRKIEWICZ MARCELI
IPC: C08K3/00
Filed: 1993-08-12
Abstract: This invention is concerned with a process for preparing ceramic-like materials suitable for a wide range of application by binding an inorganic filler of a grain size of up to 20 µm, used in the form of phosphogypsum or phosphogypsum and magnetite, or phosphogypsum and glass-forming oxides, with epoxy resin or a mixture of epoxy resin and polyester resin, the latter amounting to 80 % by volume, with the volume ratio of the resin component to the filler being 1:0.45-2. The resultant ceramic-like materials are water resistant and can be easily formed, also by casting, and additionally by mechanical working, if required. The ceramic-like materials containing magnetite show magnetic properties, while those containing glass-farming oxides are able to absorb an X-radiation of 45-55 keV and a hard radiation of 0.6-1.25 MeV. The addition of an expanding agent such as butyl isocyanate to the raw composition makes it possible to prepare an expanded material with completely closed pares. Due to very good adhesion of the ceramic-like to metal, glass, plastics, concrete it can be easily joined with these materials both during the polymerization process and after its termination, also by using a prepolymerized composition as a binder.

Inventor: KIM IN KI
IPC: B60L13/03
Filed: 1994-09-28
Abstract: The present invention relates to a switch system for personal rapid transmit which offers passengers a non-stop direct origin to destination in a small on-board unit. The switching device is installed at a certain area in a network shape including main path and diverging path and merging path therefrom. The switch system for personal rapid transit comprises guideway (10) which includes rails necessary to travelling in its inside; small vehicles (30) which automatically travel on the guideway, including a vehicle chassis (40) equipped with guidance wheels which are inserted into the inside vacancy of the guideway; and electromagnetic switch means (70), arranged at front and rear of the vehicle chassis, which performs the switching operation so that it provides attraction force to the rail when the vehicle travels on a straight main path, and that it controls the vehicle to travel into the preset direction by making a close contact with the rail when the vehicle goes into the switch section. As a result, the present invention provides, for switching at short headways of one half second without moving parts on the guideway thereby allowing a high volumn of vehicles to be operated, a swift vehicle's travel even in the switch section of the guideway thereby offering passengers rapid transit to destination.
Patent CA-2171565-A1 (CA)
Title: Recline optical system
Inventor: PETSINIS ANGELO B
IPC: G02B27/00
Filed: 1996-03-12
Abstract: An optical system for use in a viewing housing, such as a visor or a frame similar to eyeglass frames, which enables a viewer to directly view a virtual image of objects positioned at various acute angles below the viewer's direct line of sight. A primary use would be for viewing objects while the viewer is in a reclined position. The optical system compromises a series of reflectors capable of specular reflection. Light from objects to be viewed are reflected by two or more reflectors to the eyes of the viewer. One or more of the reflectors has a means for adjusting its position. This allows the viewer, in various states of recline, the ability to view objects that are in positions at various acute angles below the viewer's direct line of sight. Refraction capabilities of prisms may be utilized as reflectors, and as a means to increase the vertical field of vision to the viewer and/or reduce the size of the system.
Patent CA-2173086-A1 (CA)
Title: Data clock recovery circuit
Inventor: GARCIA PALANCAR FRANCISCO MANU
IPC: H03L7/087
Filed: 1996-03-29
Abstract: Based on a phase locked loop (PC1, CP1, VCXO) which receives an incoming data signal (DS) and generates a recovered clock signal (RC). In the event that this incoming data signal (DS) includes low frequency cycling, false phase locking can occur, consequently leading to impaired operation. To avoid this, according to the invention, there is also included a false locking detector (FLD) to which is applied the incoming data signal (DS) and the recovered clock signal (RC) and the output of which, which is added in an adder circuit (ADD) to that coming from the first loop, produces voltage pulses when both signals are not at the same frequency, provoking a non-locked state. Only when the frequency is correct, does the false locking detector (FLD) not alter loop operation.
