Patent DE-3569920-D1 (DE)
Title: Variable speed conveyor apparatus
Inventor: ARCHIBALD DAVID WALTER
IPC: B65G29/00
Filed: 1985-08-06
Granted: 1989-06-08
Abstract: Conveyor apparatus comprising a plurality of pairs of links (6, 8) which are pivotally interconnected to define an endless chain. The chain is entrained around first and second index members (2, 4). In order to provide a differential speed effect, the first and second index members (2, 4) are driven at different rates, and guide means (24, 26, 28, 30) provided to control movement of the links (3, 5) between the first and second members (24). The guide means (24, 26, 28, 30) control the folding and unfolding of the pairs of links (6, 8) to thereby allow the chain to move at different speeds on the two index members (2, 4). The spacing between alternate links changes as they move from one index member (2) to the other (4). This can be made use of in an apparatus for arraying sheet material into a series of plies. Such an apparatus comprises two of said endless chains interconnected by a plurality of parallel spaced rollers (1) arranged in an endless path. Material is fed continuously between successive rollers (1) when they are spaced apart forming loops and subsequently off-loaded by rotating the rollers (1) in a direction opposite to the direction of rotation of the endless path.

Title: Rigid link multiple disk refiner
Inventor: GOLDENBERG PHILIP HENRY
IPC: D21D1/30
Filed: 1985-09-05
Granted: 1989-12-28
Abstract: 57 A multiple disk refiner which includes a housing and a rotor hub mounted for rotation within the housing. A plurality of spaced refiner rotor disks are interleaved with spaced refiner stator disks, the pairs of disks being coaxial with the hub. The confronting faces of the stator disks and rotor disks have ribbed surfaces formed thereon for abrading and fibrillating a stock suspension as it passes in the spaces between the rotor and stator disks. The improvements of the present invention largely reside in a specific drive means for interconnecting the rotor and the rotor disks, the drive means including rigid links each of which has one end pivotally secured to the rotor and the other end pivotally secured to one of the rotor disks. A similar arrangement is provided utilizing rigid links for supporting the stator disks in proper position between the rotor disks while still providing some axial movement capability.

Abstract: An inlet feeds dust- and fume-laden air into the first chamber of a filtration unit under the suction of a blower at the far end of the unit.  Initial dust removed is by an electro-filter followed by a flat test-filter sepg. the first chamber from a larger chamber through which the air passes via a casing to the blower, and forming a settlement zone from which the air then passes into a row of parallel filter cartridges before final discharge. Increase in pressure between electro-filter and test-filter, as measured by a first meter indicates clogging of the test-filter following satn. of the electro-filter.  Failure to correct this is followed by increased loading of the cartridges, expressed as increased readings with a second meter.

Abstract: To move a plurality of interconnected segments which a zig-zag, accordeon or bellows pleat arrangement on or between which sheet elements such as projecting elements from a folded sheet are located along a transport path and to permit, selectively, expansion or compression of the segments for handling of sheet elements, and compact storage, an endless belt, preferably a gear belt sprocket chain or the like, is provided engageable with the segments. Preferably, lifting rollers are provided, selectively engageable with the belt to slightly raise the segments from transport rails, and decrease friction of the segments with respect to the rails. The segments can be stored, when empty or loaded, when collapsed against each other, and spread apart for sheet material handling. A plurality of such system can be located or adjacent each other, so that, when the segments are spread apart, suitable mixing or insertion steps can be carried out. To permit a space-saving arrangement, the transport path can be sinuous, with 180 DEG  rotating elements, having carrying rods engaging the segments coupled to a disk, turning the segments about an arcuate path defined by the travel of the carrying rods on the disk. The segments can be raised, again, by placing a cam track adjacent the disk, on which the carrying rods can run off by means of cam follower rollers.

Abstract: In an eccentric disc grinder, the grinding disc unit (7), during the machining of the workpiece, preforms a movement revolving around the eccentric shaft (4) driving the grinding disc (8). In order to prevent the rotary speed of the grinding disc unit (7) from being able to increase up to the rotary speed of the eccentric shaft (4) during idling as a result of the friction occurring at the bearing (6) carrying the grinding disc unit (7), a magnetic or electro-magnetic coupling device with a coupling part (20) fixed to the housing and a coupling part (21) fixed to the grinding disc is arranged between the grinding disc unit (7) and the housing (3). The two coupling parts (20, 21) face one another in the axial direction. One of the coupling parts is a magnet part with a magnetic field extending to the other coupling part. This interacts with the other coupling part in such a way that a holding force is exerted on the coupling part (21) fixed to the grinding disc and is thus exerted on the grinding disc unit (7), which holding force is effective in the peripheral direction of the grinding disc unit (7). <IMAGE>
