Patent CA-1296905-C (CA)
Title: Apparatus for cutting vegetation
Inventor: COLLINS IMACK L
Filed: 1987-10-19
Granted: 1992-03-10
Abstract: ABSTRACT OF THE INVENTION        Apparatus for cutting vegetation with a rotatable head carrying a non-metallic cutting line extended into a cutting plane.   As  the  line extension decreases from an established preset length an actuator in the head permits additional line to be extended automatically from a supply source  within  the  head.    The  actuator  imposes  a  back pressure against the line of magnitude correlated to the sensed pull tension wanting to extend the line outward of the head.  After the cutting line length is extended to its restored original preset length, the actuator in response to the operational forces imposed thereon secures the cutting line against further extension until a subsequent decrease in line extension is incurred.  In one embodiment an iner-tial  drag  brake  is  activated during  the course  of  line feedout and is deactivated after the length of cutting line has been fully restored.

Title: Digital power metering
Inventor: HAMMOND SCOTT H
IPC: G01R21/133
Filed: 1988-03-18
Granted: 1991-10-08
Abstract: DIGITAL POWER METERING                      ABSTRACT OF THE DISCLOSURE Method and apparatus for metering polyphase power sources in which cycles for each phase are sampled at each degree and converted to a binary representation of amplitude. Sampling commences with a zero cross-over and a first digital conversion provides range data for developing scaling factors which are retained in memory and for providing a selective gain for amplifying the same sampled degree and obtaining a second, range digital conversion. The scaling factor and the range data then are multiplied to develop a digital representation of the sample amplitude which may have as many as 21 significant bits plus a sign bit. These expanded data valuations for current and voltage then are selectively multiplied for such degree sampled to develop data available for generation of 12 electrical parameter outputs. Generally, six of these outputs will be elected by the user. Volt amperes are computed with respect to the zero cross-over events for both voltage and current samples, while quantities such as Q and var are developed by selective delayed multiplication of the unit degree samples.

Abstract: DIFFUSER FOR COLOR ANALYZER                           ABSTRACT        There is disclosed herein a diffusing device for use with photographic darkroom color analyzers when no gray card appears in any of the frames on the strip of film which have the same lighting conditions as the frame to be analyzed. The diffuser is used for determining correct color balance of an area of film which is mottled, such as human skin, by eliminating moles, freckles, dark shadows etc. from the image being analyzed with light blockers. The diffuser is made of flat translucent material in a plurality of shapes. Supports hold it above the analyzer sensor. The invention includes a variety of light blockers of various shapes made of opaque material such as sheet metal, all light blockers having the same area. A diffuser of an appropriate shape is placed within the protected image to be analyzed and moved around until it is within an area of flesh selected to be analyzed. If there is a small area of the selected area that should not be included in the analysis, such as a mole, freckle or dark shadow, then one or more light blockers of appropriate shapes are selected to be placed on top of the diffuser to block the undesired small area of light from the analyzer sensor. Then the film is analyzed in the usual manner using an exposure factor appropriate for the combination of the diffuser and light blockers.

Abstract: In cases where a first communication control unit locks a second communication control unit to communicate with the second unit, the first unit stores a data representing a time remaining until the locking of the second unit is released.  In these cases, the second unit stores a data representing an address of the first unit as a lock address corresponding to an address of a unit which locks the second unit.  In cases where a third communication control unit tries to communicate with the second unit and fails the communication with the second unit, the third unit connects with the second unit and reads out the data representative of the lock address from the second unit, and then the third unit connects with the first unit in response to the lock address and reads out the data representative of the lock remaining time from the first unit.  The third unit retries to communicate with the second unit after the lock remaining time elapses.
