Title: Non-synchronous shifting hydromechanical steering transmission
Inventor: REED BRADLEY O
IPC: B62D11/18
Filed: 1990-11-01
Abstract: NON-SYNCHRONOUS SHIFTING HYDROMECHANICAL           STEERING TRANSMISSION              ABSTRACT OF THE DISCLOSURE         An infinitely variable speed hydromechanical steering transmission includes a range-changing mechanism flanked by a pair of hydrostatic units which are commonly driven by a mechanical input to produce respective mechanical and hydrostatic outputs.  These outputs are combined in left and right output planetary gear sets which are interconnected by a cross-shaft extending centrally through the range-changing mechanism and hydrostatic units.  The range-changing mechanism includes a plurality of clutches and brakes that are selectively engaged in pairs to incrementally change the mechanical output speed on the cross-shaft and thus to operate the transmission in a plurality of forward and reverse speed ranges.  Each range change is accompanied by a step change in the hydrostatic outputs.

Patent CA-2037796-A1 (CA)
Inventor: HOLZINGER DIETER
IPC: B65H19/22
Filed: 1991-03-08
Abstract: A winding machine for winding a traveling web of paper or the like.  A carrying drum extends across the web.  A first pair of primary levers supports the pins at the end of a cylinder on which the web is to be wound.  The primary levers have one end with a fork for receiving a respective journal pin of the cylinder and another end that is mounted in the region of but eccentric to the axis of the carrying drum.  The primary levers swing the cylinder over approximately 90° around the carrying drum to a second position.  A second pair of secondary swing levers pick up the cylinder at the second position and move it to a third position along a substantially horizontal second pathway.  A first drive connected with one primary lever introduces a moment of rotation to the axis of the cylinder moving along the primary path.  A sensor detects the radial position of the cylinder and a setting device adjusts the radial position of the first drive in order to align it with the cylinder.  There may be a secondary drive for imparting rotation to the cylinder over the secondary path.

Patent CA-2050164-A1 (CA)
Title: Particle detector and particle detecting apparatus having the detector
Inventor: KOUZUKI CHIHIRO
IPC: G01N15/12
Filed: 1991-08-28
Abstract: A particle detector is designed to detect particles such as cells and blood corpuscles. The particle detector includes means for passing and recovering, through an orifice, a multilayer flow consisting of an inner layer of a conductive liquid specimen, a middle layer of conductive first sheath liquid, and an outer layer of nonconductive second sheath liquid surrounding them.      A pair of electrodes disposed on opposite sides of the orifice contact the conductive liquid.      A particle detecting apparatus incorporates this particle detector, and a detector circuit connected to the pair of electrodes detects a particle signal on the basis of differences in the electric impedance between the electrodes.      An electric current flows from one electrode to the other electrode through the conductive liquid portions, that is, the inner layer A and middle layer B. Since the outer layer C is nonconductive, the current does not flow in it. Accordingly, the diameter of the orifice effectively is substantially the same as the diameter of the middle layer.      The diameter of the middle layer. may be freely changed by varying the flow rate balance of the conductive liquids and nonconductive liquid. Accordingly, the apparent diameter of the orifice may be changed as desired.

Abstract: A vacuum assisted sheet transfer assembly to has an array of support bars 46 which guide the unprinted side of a freshly printed sheet S along a curved transfer path P. The support bars overlie the airflow inlet 44 of a manifold housing 16, with the support bars providing smooth surfaces for engaging and supporting the unprinted side of the sheet material as it is pulled along the transfer path while simultaneously limiting the flow of inlet air through elongated inlet apertures 52, 54. As air is drawn through the inlet apertures 52, 54, the unprinted side of the sheet is drawn into engagement with the support bars as it moves along the sheet transfer path. The sheet transfer assembly 10 eliminates the need for conventional skeleton wheels and the like. Marking, smearing and smudging are prevented since the printed side of the sheet S is not handled or contacted in any way as the sheet is conveyed along the transfer path p.

Title: Display control device
Inventor: FUKUDA MASAO
IPC: H04N9/31
Filed: 1992-01-30
Abstract: ABSTRACT OF THE DISCLOSURE   In a display control device according to this invention, video signals are given in parallel each of a plurality of extracting means via a common bus means.  For this reason, each extracting means can selectively extract  any of  the video signals.  Each extracting means extracts a portion of or all  of  required video  signals  in correspondence  to a display area  (an area on the display means defined by a display pattern)  to be extracted  from each of  the video signals.   The  extracted  video  signals  (concretely  real luminance signals, interpolated luminance signals, and color signals)   are  interpolated  in  horizontal  and  vertical directions  according  to  a  magnification  of  the  display pattern  on  the  display means.  This  interpolation  is  an operation to supplement picture elements corresponding to a number of scanning lines and length of the scanning lines which  become  short  when  a  specified  area  of  the  video signal, which is an original signal, is enlarged.  The video signals thus interpolated are given to corresponding display units  on  the  display  means,  respectively.   As  a  result, video signals can be developed at an optional position on the  means  with  an  optional  size,  and  in  an  optional combination.
