Patent CA-2122910-A1 (CA)
Inventor: RUDE EDWARD T
IPC: E05C17/64
Filed: 1992-11-03
Abstract: There is disclosed a friction hinge assembly capable of providing hinged motion of two elements (1, 3) with a programmable frictional torque. The frictional torque can be made to vary with the angular orientation of the two hinged elements. The frictional hinge assembly is comprised of a band (17) wrapped around a pintle (5) which is constrained to move rotationally with the first hinged element. One end of the band has a lug (19) configured to press against the second hinged element, exerting there-upon a torque about the pintle. The other end of the band has a tail (25) to which is applied a controlled force to produce the desired frictional torque between the band and the pintle.

Title: Acid catalyzed process for preparing amino acid polymers
Inventor: ADLER DAVID E
IPC: C08L77/04
Filed: 1994-09-15
Abstract: ABSTRACT The present invention relates to an acid catalyzed thermal polycondensation process for producing amino acid polymers. More specifically, amino acid polymers are produced by thermally condensing a mixture of one or more amino acids and optionally one or more polyfunctional monomers, using an acid catalyst, while maintaining an intimate admixture. Processing techniques useful for maintaining an intimate admixture include adding to the mixture one or more processing aids,using mechanical means, and combinations thereof. The amino acid polymers produced by this process are useful as cleaning and detergent additives; fertilizer and pesticide additives; personal care product additives; dispersants for inorganic particulates, aqueous emulsions, and drilling muds; and water treatment and oil production operation additives as corrosion and scale inhibitors.

Title: Exercise apparatus for simulating free-weight squat repetitions
Inventor: WILSON JERRY L
IPC: A63B21/06
Filed: 1994-12-20
Abstract: An exercise apparatus has a platform, including a seat which supports the back and head of the user, that is rotatably attached to a frame that rests on the floor. A pivot arm, which is fixedly attached to the platform and rotatably attached to the frame, allows the platform to move between a first position where the legs of a user lying on the seat are bent approximately 90 degrees at both the knees and at the hips when the user's feet are placed on a leg support that is attached to the frame, and a second position where the user's legs are substan-tially fully extended.  Movement of the platform is resisted by elastomeric weight straps which extend between the frame and the pivot arm or weight plates which are mounted on the platform.  The weight straps and weight plates can either be used separately or in combi-nation with one another.  Stops limit the travel of the platform so that the platform does not move past its desired first and second positions.

Title: Signal encoding and decoding system
Inventor: TASAKI HIROHISA
IPC: G10L25/18
Filed: 1995-03-09
Abstract: A signal encoding system A1 includes a bark spectrum calcu-lating device 2 for calculating a bark spectrum as a parameter based on an auditory model, a bark spectrum encoding device 3 for encoding the bark spectrum, a sound source calculating device 4 and a sound source encoding device 5. The bark spectrum calculat-ing device 2 includes a power spectrum calculating device 6, a critical band integrating device 7, an equal loudness compensat-ing device 8 and a loudness converting device 9. These devices are formed by engineering the functions and effects which are similar to those of the auditory model. The decoding process perform the conversion in the opposite direction. As a result, the signals can be encoded and decoded through less calculation in a manner well matching the human auditory characteristics.          When speech signals are to be encoded, it can be realized through less calculation and memory while suppressing noise components other than the speech signal.

Title: Polyurethanes cured with 4,4'-methylene-bis-(3-chloro-2,6-diethylaniline)
Inventor: ROSENBERG RONALD OWEN
IPC: C08G18/38
Filed: 1993-11-17
Abstract: Polyurethane prepolymers are disclosed prepared with mononuclear aromatic diisocyanate such as toluene diisocyanate and an aliphatic diisocyanate such as H12MDI. These prepolymers can be cured with 4,4'-methylene-bis-(3-chloro-2,6-diethylaniline) to form a cured urethane elastomer with reduced propensity to crack during the curing process, extended pour life (a slower rate of viscosity buildup after curative and prepolymer are mixed), low hysteresis, and a low level of free toluene diisocyanates and/or other toxic or volatile substances to increase worker safety during processing. It has also been found that prepolymers made from toluene diisocyanate and cured with a blend of two aromatic diamine curatives yield urethane elastomers with the same reduced propensity to crack during the curing process.

Patent CA-2162824-A1 (CA)
Title: Synchronization monitoring in a network element
Inventor: WOLF MICHAEL
IPC: H04J3/06
Filed: 1995-11-14
Abstract: In digital transmission systems, such as synchronous transmission systems according to the SDH/SONET standard, there is a need to have information on the synchronization status of the system. A known approach is to monitor the pointer activity. This is disadvantageous in that because of a hysteresis in the pointer processor, information derived from the pointer activity only conditionally reflects the synchronization status.            In a network element (1) according to the invention which forms part of a transmission system of the above type, at least one interface unit (2, 3, 4) contains, besides an optical-to-electrical transducer (5), a synchronization-monitoring device (6) which derives a synchronization status parameter, e.g., TIE, RMSTIE, by comparing an external clock frequency (Te) with an internal clock frequency (Ti). For this, the synchronization-monitoring device (6) comprises a phase-comparing device (37), a memory device (25), and an evaluating device (26).
