Abstract: The present invention provides an adjustable and automatically disengaging overload clutch for driving a tool, comprising a first clutch half frictionally engaged with a second clutch half and a coupler bracket for transmitting torque from the second clutch half to the tool. The clutch further comprises a spring connecting the second clutch half to the coupler bracket to transmit torque from the second clutch half to the coupler bracket. The spring is designed so that if a predetermined torque is exceeded, the second clutch half is released from the coupler bracket, thus preventing the transmission of any further torque. Levers associated with the coupler bracket and the second clutch half are also provided for disengaging the second clutch half from the first clutch half.

Abstract: An adjustable viscous shear coupling suitable for use in a high performance four-wheel drive vehicle comprises a housing containing a viscous fluid therein, a shaft extending into the housing, a set of outer disks non-rotatably connected to the housing, a set of inner disks non-rotatably connected to the shaft and interleaved with the outer disks, and an axially movable pressure piston which bears against the disks and adjusts the gap width between the inner and outer disks. One of the sets of disks is provided with frictional linings. The disks are brought to bear against each other in a controlled manner so that torque can be transmitted therebetween in a smooth, hump-less manner by a combination of frictional engagement and viscous shear.

Abstract: The invention relates to a portioning device for deep-frozen foodstuffs, more particularly fish. The portioning device is adapted to the portioning of parallelpipedic slabs (3). The slabs (3) are fed lying flat in the transverse position via a conveying path (6) to a drum (2) which is disposed above the conveying path (6) and whose generated surface (10) is equipped with heated separating webs (11, 12). The heated separating webs (11, 12) of the drum (2), which is driven in synchronism with the feed, subdivide the slab (3) in synchronism into individual portions (4,5). The shape of the portions (4,5) depends on the arrangement of the separating webs (11,12) on the drum generated surface (10). The subdivision of the slabs (3) into individual portions (4,5) is performed free from cutting losses, since the heated separating webs (11,12) soften up the deep-frozen foodstuffs at the cutting place.

Abstract: A device for detecting an object such as a tank in a target area and for causing a horizontal mine to be fired at the object, comprises first and second microphones which detect noise, including noise from a tank, in the target area, in infrared sensor having a directional characteristic which is narrow with respect to the target area and which extends towards the center of the target area to define a target window, and an electronic evaluation unit. The electronic evaluation unit receives acoustic signals from the microphones and calculates a correlation function from the acoustic signal. If a property derived from the calculated correlation function, for example, the correlation or the correlation gradient, exceeds a predetermined threshold, the firing mechanism of the horizontal mine is enabled. If the infrared sensor also detects the presence of an object within its target window, the electronic evaluation unit will cause the horizontal mine to be fired.

Abstract: Superabrasive cutting elements, backed compacts and methods for their manufacture are disclosed wherein metal coated superabrasive particles are cemented under HPHT conditions. The superabrasives bond to the metal of the coating and the metal coatings of adjacent particles bond to each other forming a matrix. A binding aid with thermal expansion characteristics close to that of the superabrasive particle can be infiltrated through or otherwise mixed with the particles to assist in the bonding between the metal coatings and to fill in voids. Catalyst and non-catalyst binding aids can also be used. Uncoated, smaller superabrasive particles can be interstitially dispersed among the coated particles to increase the superabrasive concentration and can self bond to form a cemented/sintered structure. Tungsten is a preferred metal coating and silicon is a preferred binding/sintering aid. The superabrasive can be diamond, cubic boron nitride, boron doped diamond or crushed, sintered polycrystalline aggregates.

Abstract: A video display system includes a frame buffer includes five sets of one or more video random access memories. An address generator for generating address locations in the frame buffer generates ship select, row select and column select address signals. Because the frame buffer comprises five sets of video random access memories, the generation of the address signals requires divide-by-five operations to be carried out. Accordingly, the address generator includes a unique divide-by-five circuit wherein the division is carried out by a sequence of additions and multiplications. In comparison to conventional systems, the video system of the present invention makes more efficient use of memeory capacity in the frame buffer.
