Patent CA-2060801-A1 (CA)
Inventor: GARNEAU FRANCOIS
IPC: B62M3/04
Filed: 1992-02-06
Abstract: ABSTRACT    A pedal mechanism for a human propulsion vehicle such as a bicycle wherein the length of each of the pedal arm is increased during the power stroke and decreased during the return stroke of the rotation cycle. It comprises a pair of sun gears rigidly attached to the frame of the vehicle, each meshed to an adjacent planetary gear of identical diameter. A lever,  radially projecting from each of the planetary gears, generate the alternative movement of the corresponding pedal arm. The levers also change the angular orientation of the pedal arms by moving them toward the power stroke zone, forcing the pedals arm to stay as long as possible in power stroke, thus giving the pedal mechanism no dead point. This pedal mechanism is very suitable for bicycle, especially mountain bicycles and racing bicycles where high power and efficiency are crucial.

Title: High efficiency light valve projection system
Inventor: DOLGOFF EUGENE
IPC: H04N5/74
Filed: 1992-02-19
Abstract: ABSTRACT OF THE DISCLOSURE       A light valve such as an active matrix LCD between crossed polarizers, utilizing, for instance, individual transistors to control each "pixel area" of the LCD and storage elements to store video signal data for each pixel, with optically shielded "dead spaces" between pixels to eliminate electric field crosstalk and non-information-bearing light bleed through, is illuminated with a bright independent light source which creates a video image projected via specialized projection optics onto an internal or external screen without distortions, regardless of the angle of projection onto the screen. Use of heat sinks, IR reflective coatings, heat absorbing optics, optional fluid and a thermistor controlled pixel transistor bias voltage injection servo circuit stabilizes image performance, maintaining accurate color and contrast levels as the LCD changes temperature. In one embodiment of the invention, use of a multi-color LCD with a stepped cavity, producing different thicknesses of LCD for the different wavelengths that pass through it, allows a linear correspondence between the wavelengths passing through the LCD to produce true black, high contrast and CRT-like color rendition. A dichroic mirror arrangement is used to overlap differently colored pixels in the projected image. Use of striped mirrors duplicate pixels, where necessary, eliminating spaces between pixels, creating a continuous image with no apparent stripes or dots. A special venetian-blind type of screen is also disclosed and methods for using the system to view three-dimensional video are also explained.

Abstract: PROCESS OF MAKING BLOCKS OF BAGS         ABSTRACT           A process of making bags having blocked stubs, which are joined by perforation lines substantially only to the lower ply while a substantially continuous slit separates the upper ply.  A tubular web of synthetic thermoplastic material is formed in longitudinal sections with a transverse perforation line extending through only the upper ply.  The web is cut a second time through both plies with offset perforations severing the lands between the first perforation line in the upper ply thus forming a continuous slit extending substantially the width of the upper ply, while leaving the lower ply attached to the stub by a transverse perforation line.  Bags having side gussets can also be made using this process.  The process can be employed as a  single bag process,  or,  by previously dividing the tube longitudinally with hot-wire welders into multiple tubes, as a multi-bag process.

Abstract: A method for decoding F2F signals as well as a device for decoding F2F signals read from a magnetic data carrier is provided. The signal read from the card by a magnetic reading head 91 is amplified by an amplifier 912 with a very high gain,  discriminated  in  a  discrimination  and  integration station 913 to receive a binary looking signal. Out of this digitized signal in a reference time acquisition station 917 a start-up time value is set and a phase is estimated to determine the correct end of a bit cell in a phase estimating station 918. In a symbol correlation station 920 the received binary signal is correlated with all possible symbol combina-tions based on the estimated phase to create a correct bit stream. This bit stream might be processed further by a bit recovery station 922 providing a corrected bit stream ready for interpretation.

Abstract: Abstract Method and Device for Continuous Surface Treatment of Bar-shaped Elongated Materials Having a Metallic Surface The invention concerns a method and a device for the thermal surface treatment of bar-shaped elongated materials having a metallic surface by means of an electric arc which rotates, magnetically driven, about the axis of the strand, whereby the arc moves between an annular electrode (anode) and the strand led through it and used as cathode.            According to the invention, the problem of developing improved measuresfor arc stabilization are, among other things, solved thereby that the electric arc is set rotating by means of a direct current magnet located behind the annular electrode in the direction of travel of the strand and, at the same time, that the magnetic field induced by the direct current magnet counteracts the pulling effect of the arc base due to the moving strand and that the annular electrode current is divided into two partial currents.            The field of application is primarily in the thermal surface treatment of bar-shaped elongated materials having a metallic surface.

Abstract: A first bill feeding plate 33 and a second bill feeding plate 34 cooperatively constitute a bill feeding passage 31 of a bill discrimination apparatus 1. The first bill feeding plate 33 is formed at a. bottom of a casing 67, which is swingably supported on the second bill feeding plate 34 through a hinge shaft 36. An opening lever 82, having an engaging hook 83 and an operating projection 84, is swingably supported at a distal end of the casing 67. The first bill feeding plate 33 is fixed to the second feeding plate 34 when the engaging hook 83 is engaged with an engaging piece 94.      Pulling up the operating projection 84 causes the opening lever 82 to start a swing motion about a bearing piece 87. This causes the engaging hook 83 to separate from the engaging piece 94, and the casing 67 rotates in a counterclockwise direction. Thus, the first bill feeding plate 33 separates from the second bill feeding plate 34 to widely open the bill feeding passage.
