Patent CA-2047161-A1 (CA)
Inventor: WEEGER ENGELBERT
IPC: B61F3/16
Filed: 1991-07-16
Abstract: A bogie for rail vehicles, particularly commuter or short-haul vehicles, has two wheel sets spaced apart in the direction of travel.  One wheel set is mounted upon a wheel mounting frame which is coupled to a tranverse member of the bogie frame by way of an intermediate beam member.  The latter is coupled to the transverse beam member by means of a resilient pivot which permits cardanic movement.   The coupling between the wheel mounting frame and the intermediate member comprises two coupling mechanisms spaced apart one each side of the longitudinal axis of the bogie and with their major axes inclined at an angle of between 10 and 40 degrees relative to the longitudinal axis of the bogie.  The arrangement is such that a lateral force applied to one wheel of the set by a curved rail will be translated into a rotational  force to rotate the wheel mounting frame and therewith the wheel set, to negate the aforesaid lateral force.       Such an arrangement reduces wheel flange wear and the risk of derailment.

Title: Pixel interlacing apparatus and method
Inventor: DEMOS GARY
IPC: H04N7/01
Filed: 1992-02-07
Abstract: An image processing system uses a pseudo-random pixel interlace method and apparatus for capturing groups of pixels as image frames. This pseudo-random method eliminates the artifacts commonly present in standard regular line raster scan imaging systems. Moreover, the pixel interlacing method permits the construction of higher resolution frames from a series of orthogonal lower resolution frames. An enhancement circuit deduces information from previous pixel group frames and contributes additional detail to the pixels of the frame being processed. The format of the pixel interlaced groups permits the present invention to be used in a wide variety of normally incompatible target display rates. The present invention can also be used in a computing system as an auto-synchronizer for processing signals from different sources.

Inventor: CHARPENTIER JACQUES
IPC: B21B35/00
Filed: 1992-03-06
Abstract: Procédé permettant d'éviter la coulure sur une machine de coulée entre cylindres.  Le procédé consiste à mesurer en au moins 20 positions équidistantes à la périphérie de l'un au moins des  cylindres  et  à  chaque  tour  la valeur d'un paramètre tel que l'intensité électrique ou la pression du fluide qui alimente le moteur assurant la rotation des cylindres ou encore le couple ou l'effort exercé par la bande sur l'un au moins des cylindres.  Dès qu'on constate au tour n en 3 positions successives une diminution de la valeur de l'un au moins de ces paramètres par rapport à la valeur aux mêmes position relevée au tour n-1, on réduit la vitesse de rotation du cylindre jusqu'à disparition de l'écart puis revient progressivement à la vitesse initiale. Ce procédé permet de couler des bandes de longueur normale sans rebut ni chute.

Abstract: An optical distance measuring apparatus wherein a processing system including a central processing unit and first and second local oscillating circuits serve to detect and calculate a phase difference between the electrical phase of a modulated signal outputted from a reference oscillator electrically connected to a light source via a modulating circuit and the electrical phase of a demodulated signal outputted from a demodulating circuit electrically connected to a light receiving portion.  Distance between the apparatus and an object is measured based on the detected phase difference with reference to the electrical phase of a reference signal outputted from a reference oscillator.  A first local oscillating signal is outputted from the first local oscillating circuit and it is then subjected to frequency conversion together with the demodulated signal in a mixer so as to output a first intermediate frequency, while a second local oscillating signal is outputted from the second local oscillating circuit and it is then subjected to frequency conversion in a mixer together with the demodulated signal so as to output a second intermediate frequency signal.          One of the first and second intermediate frequency signals is selected depending on the present distance between the apparatus and the object to be measured.
