Title: Transverse screen anchoring and adjustable deck- mating reinforcement in screen box modular systems
Inventor: JOHNSON LOUIS W
IPC: B07B1/34

Granted: 1988-03-15
Abstract: A screening basket has one or more screen decks and has upright side walls integrated with cross beams. A side beam, at approximately the center of gravity of the basket, is integrated with each of the side walls as well as with the cross beams to provide a unitary, rugged basket capable of vibratory movement on a support frame. A pair of cross shafts extend transversely of the screening basket and project beyond the side walls. These shafts are journaled in the side beams and have one projecting end geared together for opposite rotation. These projecting ends carry eccentric weights of different mass to provide an oval vibratory stroke of the screening basket upon rotation of the shafts. Adjusting mechanism is provided to adjust the relative position of the weights on the shafts to vary the angle of stroke. These weights are arranged to receive auxiliary weights to vary the amplitude of vibratory stroke as well as the shape of the stroke. The screen decks include tensioning clamp mechanism on at least one end which also is adjustable for lateral alignment with the screening. The screen decks preferably comprise at least two sections with end and intermediate tensioning clamp mechanism. These screen sections are supported on cross beams in turn supported on end bars pivotally mounted centrally thereof to the side walls of the basket to conform precisely to the contour of the underside of the screen.

Title: Frequency synthesiser
Inventor: MCCANN KENNETH D
IPC: H03L7/081
Filed: 1983-11-03
Granted: 1986-06-24
Abstract: ABSTRACT                "FREQUENCY SYNTHESISER"     A frequency synthesiser provided with frequency reduction means which includes a pulse swallow circuit PS which cancels cycles from the frequency Fo under the control of a rate multiplier RM.  To prevent phase jitter at the output of phase comparator PC due to the cancelled cycles, a compensation signal HP is derived from the swallow command signal A and from the multiplying fraction n/x of the rate multiplier.  In order to keep the DC level of the signal HP constant, the signal HP is bidirectional with respect to a mid-point voltage level and the total area of the pulses in one direction is the same as the total area of the pulses in the other direction.  The invention is applicable to both phase locked loop synthesisers (Figure 2) and direct synthesisers (Figure 11).     (Figure 2)

Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for converting bales of wood pulp sheets to fluff.  There is a non-rotating horizontal bed plate having a port through which the cutter tips of a cutting mill project from below. A cylindrical casing is journalled on its lower rim for rotation above said bed plate about a vertical axis that is perpendicular to the bed plate.  Sets of guide means are mounted to the interior of the casing.  Each guide means set holds a bale such that the bales are prevented from centrifuging radially outwardly but can settle on the bed plate.          The guide means are located so they keep all portions of the areas of the bales offset or radially spaced from the casing axis in which case the bales are driven in an orbital path as they are swept over the cutting mill.

Abstract: ABSTRACT OF THE INVENTION A pliers-type tool for setting pull-type blind fasteners of a kind requiring the stem of the fastener to be severed after it has been pulled to set the fastener.  A pair of blades mounted on pivotal holders arranged to be rocked by an actuating member of the tool after the stem has been pulled is provided.  The actuating member is slideably mounted on the pull bar and a tooth of a latch engages both parts during an initial part of the setting stroke. When the fastener has been set the latch becomes disengaged from the pull bar while continuing to retract the actuating member.  Such disengagement is controlled by a cam which is adjustable on the housing of the tool to vary the length of stroke of the pull bar in accordance with the thickness of workups in which the fastener is being set.

Abstract: ABSTRACT:       A plasma and heating treatment is performed to reduce the density of charge carrier traps adjacent the interface of an insulating layer (12) e.g. of thermally grown silicon dioxide and a semiconductor body 10. Dur-ing this plasma and heating treatment the device struc-ture so far formed (12 to 16) is covered with an addi-tional layer (20) e.g. of silane-deposited silicon con-taining hydrogen, and this additional layer (20) protects the insulating layer (12) from direct bombardment by the plasma. After the plasma and heating treatment the addi-tional layer (12) is removed from at least most areas of the semiconductor device structure (12 to 16). The heat-ing e.g. at about 400°C or less may be effected during and/or after the plasma treatment.

Abstract: A connector for a flat cable having an insulated flat conductor, and the combination thereof. The connector comprises a metal plate which is bendable along a bending line to form two arms, each arm having a tubular member extending toward the other arm and positioned so as to be coaxial when the tubular members are opposed. The interior size of one tubular member is larger than the exterior size of the other tubular member by at least 1/3 the thickness of the conductor so that the other member is receivable in the one member. Both members are deformable at their ends so that when the arms are brought together, the smaller member deforms inwardly and removes insulation from the conductor and also deforms the conductor without passing through the latter and the larger member deforms outwardly and removes insulation from the conductor without passing through the latter. The deformed portions of the members conductively contact the conductor.

The liquid and gases  are  separated by a phase separation-collection device,  and the  liquid portion is collected and recycled through a central conduit by a recycle pump having its impeller located  in  the  upper portion of the  conduit.   The pump impeller bearing is pressurized and purged by a clean com-patible fluid,  such as hydrogen or oil, to exclude reactor liquid  containing  fine  solids  from the bearing and  seal surfaces.   A second liquid recycle pump can be provided at the lower end of the reactor and operated in series flow relationship with the upper pump.   The second pump can be located either within the reactor vessel or external to it and connected thereto by conduits.
