Title: Electronic odometer
Inventor: SHIDA MAKOTO
IPC: H03K21/40
Filed: 1990-05-22
Granted: 1997-03-25
Abstract: The present invention relates to an electronic odometer.  Integrated distance travelled data to be stored in a nonvolatile memory is divided into three portions, i.e., high order digital data, medium order digital data, and low order digital data.  A plurality of memories constituting the nonvolatile memory are provided.  The digit which represents the medium order digital data is used to select addresses or part addresses within the memories which are to be used.  The high order digital data which is required to be the most reliable of the three portions are written into at least three memory positions which have been selected by the medium order digital data and the low order digital data is written into at least one of the rest of the memory positions selected by the medium order digital data.  When extracting the integrated distance travelled data from these memories, the high order digital data is determined by applying majority rule to the data read out from the at least three selected memories.  The reliability on the integrated distance travelled data is enhanced by the application of majority rule.

Title: Apparatus for timing races
Inventor: NOBS ERWIN
IPC: H04N7/18
Filed: 1990-06-14
Granted: 2000-05-16
Abstract: This race timing apparatus of the video finish type includes a photo sensitive CCD bar (5) which may be read at a predetermined frequency in correspondence with the run past speed (Vi) of the image of the race. The images are stored and visualized by means of a commercial recorder (22) and monitor (23) of a fixed standardized sweep frequency.       Since the image acquisition frequency by the bar is not synchronous with the visualization frequency, one proceeds with the generation of image parts using buffer memories (19, 20), the image parts being next stored in an image memory (21) and then read in a discontinuous manner by jumping over image parts in synchronism with a standard TV sweep. The apparatus enables the offering of a system at a low overall cost price since it employs a recorder and a monitor currently obtainable on the market.

Title: A bearing holder for bearing mounted on journals
Inventor: ROGGE DIETER
IPC: F16C13/02
Filed: 1991-01-08
Granted: 2001-05-01
Abstract: A bearing holder for bearings mounted on journals includes a lower support socket secured to a frame, and a cover part pivotally connected with the socket. The cover part is able to be locked in a shut position, folded onto the bearing positioned in the support socket. In order to provide a bearing holder of this type, which makes possible the removal and insertion of the journals without releasing the cover parts by hand, and without having to be pivoted and locked for the purpose of opening and shutting, cover parts are pivotally bearinged on two upper lateral parts of the support socket about axes which are parallel to the journal. Such cover parts include an upper, longer arm and a lower, shorter arm of a two-armed lever. The lower arm forms an actuating part, which, in the folded back, opened position of the cover part, extends into the interior of the support socket, so that by lowering the bearing, which abuts against the same and is placed on the journals, into the support socket, the bearing pivots the cover parts into shut position, in which the latter has its inner, arcuate sides in snug engagement with the bearing. Thus, the cover parts which, in this manner, are folded into their shut setting, and have their end faces abutting against each other, are provided with an automatic device locking the cover parts together.

Title: Air delivery system and oven control circuitry cooling system for a low profile impingement oven
Inventor: CRISP DUANE L
IPC: F24C15/00
Filed: 1991-05-06
Granted: 1995-01-17
Abstract: ABSTRACT An impingement oven comprising a cooking chamber, a conveyor, and a plurality of plenums.  A plurality of finger duct members attached to each plenum are located above and below the conveyor. Adjacent sidewalls of adjacent duct members are tapered relative to one another to define an outwardly tapered air return space in a direction away from the plenum.  A plurality of air deflectors are secured to an inner surface of each duct member for deflecting air through a plurality of nozzles located on the duct member.  A partition between the plenums segregates return air flowing from the cooking chamber to adjacent plenums.  For at least two ovens stacked one above the other, the invention further includes a cooling system having a cooling compartment and a central cooling duct for drawing cool air from near floor level and moving the cool air upwardly to cool the control circuitry for each of the stacked ovens.  The cool air is then exhausted out of the cooling compartment to substantially insulate the oven control circuitry from the radiating heat of the oven below.
