Title: Method for measuring the weight of a suspended load
Inventor: ANDERSON ROBERT N
IPC: G01G19/14
Filed: 1992-01-08
Abstract: Abstract of the Disclosure A method for measuring the weight of a suspended load, such as the bucket of a dragline, is disclosed.  The method incorporates visual observations by a person such as a test engineer, or the operator of the dragline.   During a dig cycle, once the steady state operation of the hoist is achieved, sampling of parameters such as hoist motor armature and field currents, and hoist and drag rope lengths, is performed.  Using the calculated values of the force applied to the load and the geometry determined by the various  rope  lengths,  the  weight  of  the  suspended  load  is calculated for each sample in the dig cycle.  The calculated weight data may be accepted or rejected based upon the presence of dynamic factors observed by the test engineer or operator, or evident in the data.   Calibration of certain values,  such as the hoist efficiency,  may  take  place  on-site,  rather  than  relying  on theoretical or modeled values.  If multiple hoist motors are used, data is sensed at each, and the hoist pull force applied by each individually calculated, for improved accuracy.

Title: Multi-roller electrostatic toning
Inventor: PICKETT JOHN E
IPC: G03G15/08
Filed: 1992-01-08
Abstract: Non-magnetic and non-conductive powdered toner is applied to a rotating image cylinder having an electrostatic pattern. A container having a closed bottom and sides and open top contains the powdered toner. The powder is fluidized by introducing air through a pervious closed bottom of the container, and by vibrating the container. The toner is simultaneously stirred and electrically charged to a potential of greater than about 7kv (plus or minus polarity) by rotating elements with radial pointed appendages in the container. Toner is transferred from the container to an image cylinder at an exposed nine o'clock position of the image cylinder by a plurality of transfer cylinders. A first transfer cylinder is mounted so that its periphery is just above the open top of the container and an applicator cylinder has its axis below the axis of the first cylinder, and its periphery adjacent both the first cylinder and the image cylinder. A second cylinder is for the removal of opposite sign charged toner and low charge toner from the applicator cylinder.      Scrapers scrape unused toner from the first and applicator cylinders so that it falls into the open top of the container.

Inventor: KNAUER PETER
IPC: B41F7/02
Filed: 1992-01-14
Abstract: To positively lock in position  a pair of eccentrically journalled blanket cylinders (3, 6), movable between three positions, namely in engagement with a first pair of plate cylinders (1, 4), or a second pair of plate cylinders (2, 5), or in engagement with neither plate cylinder, the blanket cylinders having a printing substrate  passed therebetween for perfecting printing, the eccentric bearings (7, 8) for the blanket cylinders are secured to operating disks(9, 10) which, each, are coupled to a scissor-link arrangement formed by two pairs of links (16, 18;17, 19), joined at a common pivot point.  Pneumatic cylinder-piston arrangements move the pivot points (1618, 1719)      to compress one of the scissor link pairs to V position,while the other  link pair is moved  to slightly over-center in-line position for a toggle or locking effect;  when both scissor link arms are in half-open V position, the blanket cylinders are disengaged from the plate cylinders. Abutment stop means, located between the blanket cylinders, receive the pivot points, when the link arms are in essentially in-line or toggle position, and adjustment bolts (42, 43, 44, 45) can control the position of the scissor link arms, when in V position for accurate adjustment of the locked position of the blanket cylinders.

Title: Methods for making toothed belt construction
Inventor: THOMAS DANNY L
IPC: B29C43/02
Filed: 1990-07-20
Abstract: An improvement is provided in a method of making a toothed belt construction that has a toothed surface means and that comprises a belt sleeve from which individual endless belts are subsequently cut in a conventional manner, the belt sleeve having a preformed fabric means lining the toothed surface. The method includes the first step of forming the preformed fabric to have serially disposed tooth-shaped projections throughout its length so as to line the toothed surface thereof. The fabric is disposed onto an externally toothed cylindrical mould member used to form the belt sleeve.      The belt sleeve is formed on the mould member with material so that the fabric forms part of the belt sleeve with the material. The preforming fabric is formed from an endless tubular sleeve that has the tooth-shaped projections formed therein while the fabric means is still in the endless tubular sleeve form thereof. The endless tubular sleeve in its pre-formed condition is disposed on the mould member by axially sliding the sleeve in a telescoping manner onto the mould member before the step of forming the belt sleeve. The fabric is disposed in the endless tubular sleeve form thereof between a pair of cooperating and telescoped cylindrical mould members respectively having teeth that index with each other to form the tooth-shaped projections of the fabric. One of the mould members is formed by deforming a first sleeve of polymeric material under heat and pressure against a cylindrical mould device that has teeth thereon. The first sleeve is removed from the mould device and is inverted. A second sleeve of polymeric material is deformed under heat and pressure against the inverted first sleeve to form teeth in the second sleeve.   The sleeves are inverted while the second sleeve is against the first sleeve. The inverted sleeves are separated to comprise the cylindrical mould members to be utilized to form the fabric therebetween.
