Inventor: GRAY DAVID A
IPC: B27L11/00
Filed: 1995-09-14
Abstract: An improved chute and spout assembly for use with a wood chipper that clears logjams by the use of hydraulic rams attached to the chute near the chipper. The rams move between an extended position, for moving the logs, and a retractedposition, when the logs are sliding by gravity on the interior surface of the chute. The rams are oriented and spaced apart in order to move the logs when jammed without interfering with each other when more than one ram is extended into the interior of the chute to move the logs. When retracted, the ends of the rams areapproximately flush with the interior surface of the chute. Each ram is independently controlled for flexibility in clearing logjams.

Title: Simplified bar code decoding method
Inventor: WANG YNJIUN P
IPC: G06V30/224
Filed: 1995-09-14
Abstract: The reading and decoding of two-dimensional bar codes in a bar code reader are simplified and field loading of different data character sets is en-abled. Decoding of bar/space patterns of a bar code is simplified by deriving T-sequence data representative of the bar/space pattern and then processing a majority of the T-sequences directly into decoded values representative of the bar/space pattern. Dynamic load-ing of new data character sets fully or partially superseding a factory installed default character set correlation listing is enabled by use of loadable correla-tion listings keyed to foreign language characters, symbols, words or phrases relevant to particular applications. The loadable correlation listings can be en-coded into a two-dimensional bar code and laoded via a reading of the bar code by the bar code reader.

Patent CA-2178129-A1 (CA)
Title: Current Flow Indicator
Inventor: JONES THADDEUS M
IPC: G08B17/06
Filed: 1996-06-04
Abstract: An apparatus connectable between a current source and an electrical load for indicating current flow through the load above a threshold level. The indicator includes two negative temperature coefficient (NTC) thermistors, and a neon indicator lamp. The first thermistor is connected directly in series with the electrical load and the second thermistor is connected in series with the neon lamp. The thermistors are packaged together by an epoxy resin which thermally couples the thermistors so that both thermistors operate at substantially identical temperatures. Current flow above the load's operational threshold level causes the first thermistor to heat to anequilibrium temperature well above the ambient temperature. At this elevated equilibrium temperature both resistors have extremely low resistance values. Thelow resistance value of the second thermistor permits maximum current flow to the neon lamp which illuminates the lamp. As the current flow through the load drops, the self-heating experienced by the first thermistor decreases and the resistance value of the second thermistor increases. When the current flow through the load fallsbelow the load's operational threshold level, the resistance value of the secondthermistor is sufficiently high to limit the current flow to the neon lamp and prevent illumination. The failure of the neon lamp to illuminate provides a visual indication that the current flow to load is below the load's operational threshold.
