Title: Pop-up temperature indicator for use in a 3-cd type air compressor or similar device
Inventor: RAY JENNIFER L
IPC: G01K13/02
Filed: 1999-02-08
Abstract: A temperature indicator for indicating when a specified temperature has been exceeded in a fluid flow through a conduit. Such conduit having an aperture and the temperature indicator being mountable in such aperture and engagable therewith such that the temperature indicator projects through such aperture and into such fluid flow in such conduit. The temperature indicator includes a housing which substantially encloses an internal chamber and has a bore extending from the internal chamber to an external surface of the housing. An indicator member is disposed, at least in part, within the internal chamber and extends into the bore. A biasing element is disposed within the internal chamber and exerts a biasing force between the housing and the indicator member and urges the indicator member toward the bore. A bonding agent forms a bond between the indicator member and the housing to thereby restrain the indicator member from movement toward the bore under action of the biasing element. The bonding agent is thermosensitive to substantially release the bond between the indicator member and the housing when a temperature of the bonding agent substantially reaches the specified temperature.

Title: Fault indicator providing contact closure on fault detection
Inventor: SCHWEITZER EDMUND O JR
IPC: G01R31/08
Filed: 1999-03-11
Abstract: A fault indicator for detecting the occurrence of a fault current in a monitored conductor includes a rotatably mounted indicator flag. The flag is positioned in either a reset indicating or a fault indicating state by a magnetic pole piece, which is magnetized in one magnetic direction or the other by momentary application of a current in one direction or the other to an actuator winding on the pole piece. An auxiliary magnetic circuit comprising an auxiliary pole piece magnetized by the actuator winding, a reed switch and a bias magnet magnetically aligned to oppose the reset magnetic orientation and reenforce the trip magnetic orientation of the magnetic pole piece provides contact closure upon occurrence of the fault current.

Title: Set of progressive multifocal ophthalmic lenses
Inventor: BAUDART THIERRY
IPC: G02C7/06
Filed: 1997-09-09
Abstract: The invention concerns a set of progressive multifocal ophthalmic lenses, each having a first progressive multifocal surface and a second surface preferably spherical. It proposes to define the set of lenses with regard to the optical characteristics of the lenses, and particularly wearer power and oblique astigmatism, in worn conditions. For this purpose, the invention defines an ergorama associating with each sight direction in worn conditions a target object point, and a given power. This ergorama supplies a power target for a definition by optimisation of the lenses, and is used in a radii plotting programme for calculating the optical characteristics during optimisation. The set of lenses has substantially identical optical performances for a given addition, whatever the power of the far vision reference point.

Title: Method for signalling a noise substitution during audio signal coding
Inventor: DIETZ MARTIN
IPC: H04B1/66
Filed: 1998-03-13
Abstract: The invention relates to a method for signalling a noise substitution during audio signal coding. According to said method, the audio signal is first transformed in the frequency range to obtain spectral values. The spectral values are subsequently grouped to form spectral value groups. On the basis of a detection whether a group of spectral values is a noise group or not, a coding table is allocated to a non-noise group or a tonal group by means of a coding table number for redundancy coding of the same. If a group is a noise group it is allocated an additional coding table number which does not refer to a coding table in order to signal that this group is a noise group and that it must not be redundancy coded. By signalling noise substitution by means of a Huffman-code table number for noise groups of spectral values which are for instance scale factor band sections and which must not be redundancy coded, an opportunity is provided for implementing availability of a noise substitution in a scale factor band in the bit flow syntax of the MPEG-2 Advanced Audio coding Standard, without intervening in the basic coding structure and without having to touch the structure of the existing bit flow syntax.

Title: An improved electrochromic medium capable of producing a pre-selected color
Inventor: GUARR THOMAS F
IPC: G02F1/1524
Filed: 1998-03-26
Abstract: An improved electrochromic device, the device incorporating an electrochromic medium that comprises at least three electroactive materials having absorption spectra that add together such that the color of the electrochromic medium can be pre-selected by individually choosing the concentrations of the at least three electroactive materials. The electrochromic medium generally maintains the preselected perceived color throughout its normal range of voltages when used in an electrochromic device. The at least three electroactive materials include at least one electrochemically reducible material (cathodic material), at least one electrochemically oxidizable material (anodic material) and at least one additional electroactive material which may be either an anodic or cathodic material. Thus, there are always three electroactive materials present in the medium, with at least two either being anodic or cathodic materials. The pre-selected color may be chosen from a wide variety of colors and may be, for example, red, orange, yellow, green, blue, purple. For electrochromic mirrors for motor vehicles, a presently preferred color is gray.

Abstract: A baler plug removing system for unplugging a conventional hay baler without the user having to risk bodily injury or leave the comfort of the tractor cab.  The inventive device includes a bar member having an engaging face that is extendable between a pair of feed rollers, a plurality of wheels rotatably attached to the bar, a pair of opposing tracks that are secured to the conventional baler that receive the plurality of wheels, a pair of front bearing for guiding the front of the bar, a pair of rear bearings for guiding the rear of the bar, and a pair of hydraulic cylinders connected to the bar for extending/retracting the bar along the tracks. A plurality of push hooks are preferably connected to a rear portion of the bottom surface of the bar for pulling in hay from the pickup into the feed rollers. A plurality of pull hooks are preferably attached to the bottom surface of the bar adjacent the engaging face for pulling tightly compacted hay from between the feed rollers. It can be appreciated that other well-known means of extending/retracting the bar along the tracks, such as an actuator chain gear system, may be utilized instead of a pair of hydraulic cylinders.  When hay becomes plugged between the feed rollers of the conventional baler, the user actuates the pair of hydraulic cylinders that extend the bar into the feed rollers thereby pushing and severing the plugged hay. When the user retracts the bar the pull hooks catch upon the plugged hay drawing it away from the feed rollers thereby unplugging the baler without the user having to leave the tractor cab.

Inventor: KOURILOVITCH ANDREI
IPC: G01D5/347
Filed: 2000-02-07
Abstract: The present invention relates to optical reading systems for incremental encoders. An incremental encoder, whether linear or angular, consists of an encoding disc or linear scale with optically transparent and non-transparent or reflecting and non-reflecting patterns, with a light source on one side and photo detectors on the other side. The light source in this invention produces light stripes. These light stripes are adjustable to match the pattern of the encoding element. A photo detector assembly detects the light stripes going through or reflected from the encoding element.        Description of the prior art Incremental encoders, in their simplest form, produce electronic pulses with light, encoding elements and photo detectors. An optical mask between the light and the encoding element or between the photo detector and the encoding element enhances the performance of this assembly and makes it possible to read very fine lines. Other known devices for more precise readings use diffraction gratings and measure their relative shifts. These methods are costly because of the necessary time to adjust the optical elements.
