Patent CA-2066087-C (CA)
Inventor: TAKAHASHI AKIRA
IPC: G11B11/105
Filed: 1992-04-15
Granted: 1999-09-07
Abstract: A magneto-optical recording medium has a recording layer whereon information is magneto-optically recorded.      A readout layer is provided on the recording layer. The readout layer has a compensating temperature that is located between room temperature and the Curie temperature. In the readout layer, upon an application of a light beam, the in-plane magnetization occurs at room temperature and a transition from the in-plane magnetization to vertical magnetization occurs as the temperature of the irradiated area of the readout layer rises above a predetermined temperature. By employing this magneto-optical recording medium, with an application of a light beam that is intensity-modulated into two levels, only a spot having a temperature not less than a predetermined temperature is involved in the reproduction; therefore, a recorded bit with a size smaller than the diameter of the light beam can be reproduced, thereby greatly increasing the recording density. Further, the level of the reproduced signals is increased, and crosstalk from the adjoining tracks is reduced; thus, information recording and overwriting can be conducted more easily.

Title: Rotating gold pan for separating gold particles from ore
Inventor: KRENZLER LEO M
IPC: B07B13/11
Filed: 1993-01-05
Granted: 1998-08-25
Abstract: A separator pan (10) is set into a rearwardly leaning position (Fig. 4). A lower portion of the pan sidewall (28) slopes downwardly as it extends outwardly from the pan bottom (12). A spiral rib (32), inside of the pan (10) slopes upwardly as it extends axially outwardly from the interior of the pan (10).  Pan (10) is rotated in a direction causing the spiral rib (32) to coil inwardly. Large particles of gold ore, introduced into the pan (10), gravitate out from the pan, owing to the sloping nature of the lower portion of pan sidewall (28).  Smaller particles, including small particles of gold, are trapped between spiral rib (32)  and sidewall  (28)  and bottom wall (12) of pan (10).  As the pan (10) rotates, these small particles are moved inwardly and into a hub cup (14).

Abstract: Differentially  expressed  Leishmania  genes  and proteins are described.   One differentially expressed gene (A2) is expressed at significantly elevated levels (more than about 10 fold higher) in the amastigote stage of the life cycle when the Leishmania organism is present in macrophages than in the free promastigote stage.  The A2 gene encodes a 22 kD protein (A2 protein)  that is recognized by kala-azar convalescent serum and has amino acid sequence homology with an S-antigen of Plasmodium falciparum  Vietnamese  isolate  VI.     Differentially expressed Leishmania genes and proteins have utility as vaccines,  diagnostic  reagents,  as  tools  for  the generation of immunological reagents and the generation of attenuated variants of Leishmania.

Title: Method of cutting compressible materials
Inventor: GEFFROS MIKE
IPC: B26D7/08
Filed: 1991-04-26
Granted: 1999-09-14
Abstract: A method of cutting stacked layers of compressible material utilizing a steel rule cutting die. An open cell foam member (18, 20) is placed in the area between spaced portions of the cutting die (16) to define a flat upper surface substantially flush with the sharpened upper edge (16a) of the cutting die. The stacked layers (22) of compressible material are placed on top of the foam member (18, 20) and on top of the sharpened upper edge (16a) of the die and the upper platen (10) of the associated press is Powered to precompress the stacked compressible layers (22) prior to the cutting operation by the die. The foam member ( 18, 20) is an open cell member and has a compressibility such that it maintains a flat upper face ( 18a, 20a) flush with the upper cutting edge of the die during the precompression of the layers (22) and thereafter moves downwardly in a smooth translatory manner to allow the layers (22) to be moved downwardly through the cutting die. The invention methodology avoids distorsion of the fabric pile during the cutting and allows the cutting of even very high stacks of compressible fabric without substantial variation in the shape or length of the cut pieces and without any substantial beveling of the edges of the cut pieces.

Abstract: Method and apparatus for effecting mode switching from a transmission mode to a command mode of an intelligent modem operatively coupled to a digital data device and a telephone line is disclosed. A termination of the modem's transmission mode (400) is effected after a predetermined silent time interval (406) in which no data is received from the device and prior to the transmission of additional data on the line. Operation of the modem switches to a buffer mode (410) in which data sent from the device is temporarily stored instead of being transmitted on the telephone line. If the stored data is a proper escape sequence (424) operation of the modem switches to the command mode. If a proper escape sequence is not received, operation of the modem switches to a purge mode (418) in which the stored data is transmitted on the telephone line. The apparatus comprises a data interface, a novel modem controller and a modem engine. The modem controller (20) includes the data buffer (60) for storing the data received from the digital data device (22) when operating in the buffer mode.

Title: Snowmobile
Inventor: MARIER GREGORY J
IPC: B62M27/02
Filed: 1994-06-08
Granted: 2000-05-16
Abstract: A snowmobile construction wherein the components are laid out so as to improve the center of gravity of the snowmobile and position the major components so that they will exert a large portion of their weight on the drive belt.      The snowmobile includes a built-up frame assembly that defines a cradle in which the engine is positioned and which drives the drive belt through a pair of transmissions. One of these transmissions is disposed within the frame assembly and in a casing carried by an opening in one side of the frame assembly. The snowmobile is steered by a steering shaft that extends across the top of the engine and through a space between the exhaust manifold of the engine and the engine so as to provide a compact assembly. The positioning of the transmission inboard of the frame permits the use of a forwardly positioned seat with foot rests disposed outwardly of the transmission but closely adjacent the sides of the frame.
