Patent CA-2088638-A1 (CA)
Inventor: DORSCHT JOHN P
IPC: B02C21/02
Filed: 1993-02-02
Abstract: A tumble grinder is disclosed in which material which is already sufficiently small in size, primarily being abrasive aggregate or earthen material, may be discharged from the receptacle to bypass the comminution apparatus and thus substantially reduce wear thereto.  A portion of the cylindrical wall of the receptacle is provided with classifying openings, for example by providing a screened opening as a band around the receptacle.  The classifying openings permit material which is already smaller than the size of the openings to fall therethrough, thereby bypassing the comminution apparatus.  Preferably, a conveyor is positioned beneath the receptacle, to catch and discharge the material which falls through the screen or other classifying openings to a pile located away from the receptacle.          Sidewalls positioned on either side of the receptacle stop any material which is flung out to the side, and redirect it down onto the conveyer.  The apparatus may be advantageously mounted on a trailer, for towing from site to site.  In such an arrangement, it is advantageous to provide an integrated, transportable system, in which the receptacle is moveable between an operating position and a transportation position.

Patent CA-2095579-A1 (CA)
Title: Sod roll stacker
Inventor: SCHOUTEN BEN H
IPC: A01B45/04
Filed: 1993-05-05
Abstract: A sod roll stacker assembles sod rolls on a platform member to form an approximately square layer of sod rolls. When the layer is complete, the platform is removed allowing the layer to fall on a support member below the platform. The platform is then moved to its former position. The above cycle of operations is repeated. The support member is rotated about a vertical axis through about 90° after each cycle so that a stack of rolls is built up having the axis of the rolls in each layer at about 90° to the adjacent layer, thereby increasing the stability of the stack.

IPC: B65H54/28
Filed: 1993-08-13
Abstract: ABSTRACT OF THE DISCLOSURE             CABLE REEL LEVEL WIND MECHANISM         A cable guide mechanism for evenly winding a cable for an electric powered vehicle onto an on-board reel having a cable guide that is reciprocated across the reel to neatly and closely wind the cable onto the reel.  The cable guide is driven by a drive linkage to reciprocate in proportion to rotation of the take-up reel.  The drive linkage includes a lever having a fixed pivot end and a free end attached to the cable guide. An eccentric crank driven by the rotation of the take-up reel is attached to a connecting rod that connects the end of the crank to an intermediate point on the lever arm.  Accordingly, the range of reciprocation of the cable guide is substantially greater than the diameter of the path swept out by the crank, and the drive linkage may be contained in a compact package.

IPC: G11B7/095
Filed: 1993-09-14
Abstract: A recording and/or reproducing apparatus for a disc-shaped optical recording medium includes a rotation drive mechanism, a head device, a discriminating device, a first processing device, a second processing device, a third processing device and a controller. A disc-shaped optical recording medium is loaded on the rotation drive mechanism and is run in rotation at a constant linear velocity. The head device includes a laser light source and a photodetector unit and is movable in the radial direction of the disc-shaped optical recording medium for recording/reproducing information signal on or from the disc-shaped optical recording medium. The discriminating device discriminates the type of the disc-shaped optical recording medium loaded on the rotation driving device The photodetector unit includes first, second and third photodetectors. The first processing circuit takes a difference between output signals from the first photodetector and those from the second photodetector. The second processing circuit takes a sum of output signals from the first photodetector and those from the second photodetector. The third photodetector generates an error signal based on an output signal from the third photodetector. The controller selectively changes over an output from the first processing circuit to an output from the second processing circuit and vice versa based on a detection output from the discriminating device to produce reproducing signals.
Patent CA-2108449-A1 (CA)
Title: Method of compensating for the movement of the antenna for a sonar
Inventor: DOISY YVES
IPC: G01S15/50
Filed: 1992-03-27
Abstract: A method for towed sonar arrays, wherein antenna movement is electronically compensated to suppress the Doppler shift in the fixed echoes. For this purpose, a series of M sensors in a towed linear antenna (203) which includes N sensors (205), and where M < N, are selected and electronically switched so that they scan the antenna in a phantomlike manner in the opposite direction to antenna movement and at twice its forward speed. To avoid having too many physical sensors, their signals are interpolated to obtain a sufficient number of phantom sensors to reduce the increment of the phantom sub-antenna's movement and thereby suppress the interfering lobes caused by the incremental nature of said movement. The method allows the sensitivity of sonars to be increased without increasing their power.

Abstract: Summary Process and Installation for the Identification of Materials This invention consists of a process and an installation to identify materials. Materials are exposed to laser energy, and after the material is heated, the thermal radiation of the material is measured. Following this, a material-specific evaluation takes place, based on optical and thermal material properties. At least one area on the surface of the material to be identified is subject to a short, point-shaped exposure of laser radiation. The material-specific thermal impulse response for the radiated surface area of the material is both locally and temporally measured, and evaluated as regarding the kind of material.

Abstract: For a long time human-powered flight has been attempted but with no success so far.     This invention solves this old problem because it uses the flier's weight rather than his power. Flight is accomplished by alternatively loading the wings with the flier's weight if the wings are placed one on top of the other, or by the alternative loading of the wings' connecting point and the wings' ends if they are connected on the same plane.

Title: Process and device for the fabrication of tobacco products with a variable density of tobacco
Inventor: BABEY JACQUES
IPC: A24D1/00
Filed: 1994-06-03
Abstract: When manufacturing a cigarette which is completely or partly formed of strands or sides of expanded tobacco or short strands, or else containing a smaller amount of tobacco, difficulties are encountered in obtaining a cigarette which has an acceptable measured compressibility value. By providing a cigarette-manufacturing machine (1) with a cam (3) which has at least one additional bearing surface (32A, 33A, 34A, 35A) it is possible, just before the operation (15) of nipping the top off the twist (20), to compress a certain number of regions (22) of the said twist, thereby increasing the tobacco density in these regions. A cigarette including one or more regions (22) with a tobacco density which has been increased in this way has a measured compressibility value which is equivalent to a normal cigarette. <IMAGE>
