Patent CA-2080100-C (CA)
Title: Humanly operable, recreational, readily disassemblable water cycle
Inventor: SCHMID AUGUST
IPC: B63B7/00
Filed: 1992-10-07
Granted: 1998-01-20
Abstract: To permit rapid assembly and disassembly of the water cycle so that, when disassembled, it can be stored or transported in minimum space.  The cycle, which has at least three flotation bodies (2a, 2b, 2c), which are elongated or torpedo shaped, is formed of tubular frame elements which are coupled together by push-in connectors with spring-loaded pin locks (9, 30, 30', 33, 41) so that individual frame elements (6,7,8; 12,13,14; 24,25) of the cycle can be disassembled into the frame elements, or, selectively, snapped together.  The flotation bodies are preferably inflatable and formed with a keel.  A pedal and crank arrangement is coupled to a transmission which can drive a propeller or, directly via a chain, a paddle wheel.  To prevent damage to the propeller if it meets an obstruction, a propeller attachment and a housing therefor is releasably mounted on a frame for pivoting movement upwardly and downwardly, with various positions of the propellers selectable by a spring loaded engagement hook engaging in recesses in a positioning disk; and, to permit lateral deflection, the housing is rotatable about an axis transverse to the direction of movement (A) of the cycle, and positioned in predetermined location by a spring-loaded claw clutch to permit release, in the lateral direction, if an obstruction is encountered.

Patent CA-2102194-C (CA)
Inventor: LAROSA CHRISTOPHER P
IPC: H04L7/00
Filed: 1993-01-21
Granted: 1998-11-24
Abstract: The present disclosure includes a discussion of a method of phase adjustment for use in a clock recovery scheme. The phase adjustment circuit automatically holds the clock phase during periods of poor channel quality. The clock recovery scheme generates a sampling clock signal (139) which is synchronous with the received signal (131). Additionally, the clock recovery scheme generates at least two error signals (347, 349, 351, 353) which indicate the quality of the received signal at different sampling phases. The smallest error signal is referred to as the minimum error value. Each error signal (347, 349, 351, 353) is compared to the minimum error value, creating a corresponding normalized error magnitude signal. Each normalized error magnitude signal is processed to determine the desired phase of the sampling clock signal. Dependent upon the processing of the normalized error magnitude signals, the phase of the sampling clock signal is either shifted or maintained until the next sampling point.

Title: Salt composition containing calcium magnesium acetate and sodium silicate
Inventor: SIMPER JACK L
IPC: C09K3/18
Filed: 1992-03-05
Granted: 1999-09-07
Abstract: The inventive composition contains salt, calcium magnesium acetate (CMA) and sodium silicate, and may optionally contain sodium ferrocyanide, diatomaceous earth, and/or other materials. The composition is useful for facilitating the melting and removal of snow and ice, and is stable and non-corrosive. The inclusion of both CMA and sodium silicate in the salt composition provides better corrosion resistance than can be obtained by the inclusion of comparable quantities of either CMA or sodium silicate alone. The inventive salt composition is considerably less expensive to manufacture than CMA-containing salt compositions which provide comparable corrosion resistance.

Patent CA-2113095-C (CA)
Inventor: SUTTON PHILIP
IPC: G01S17/89
Filed: 1992-07-09
Granted: 2002-03-26
Abstract: An etectro-optical detection system for detecting objects (12) em-bedded within a partially transmitting medium comprises means (20) to receive electromagnetic radiation in two close spectral channels (28, 212): a signal channel (212) where the wavelength and bandwith of the signal channel are optimised to correspond to the peak of transmission of the medium and a reference channel (28) where the wavelength and bandwidth are selected to correspond to a spectral region where attenua-tion in the medium is high. The signal and reference channels are then subtracted (213) so as to remove the effect of reflected radiation from the signal channel (212). The signal is processed digitally (218) to provide an enhanced image of the field of view. In a particular arrangement for de-testing objects underwater a CCD TV camera (20) is used with three sep-arate CCD detector arrays providing concurrent red (R); green (G), blue (B) output signals. The green and blue signals are combined in an adjus-table ratio to provide the image signal to match the prevailing conditions of the partially transmitting sea. A notch filter is employed to cut out light in a spectral band between the signal and reference channels.
