Abstract: The invention relates to a method and a shielding housing for shielding a printed circuit board, or a part of it, from disturbances caused by electromagnetic interference (EMI). In the method, in the manufacturing phase of the printed circuit board there are cut in the board slots (U) through the printed circuit board (pc), the length of the slots being L. The first part (2) of the housing is soldered to the printed circuit board (pc) in such a way that it approximately interconnects the ends of the cut slots (U). This first part constitutes one side wall of the shielding housing. The second part (1) of the shielding housing is made up of a cover (5) and three side walls, in which there is formed an inside groove having a height which corresponds to the thickness of the printed circuit board. After the soldering of the components, this second part (1) is slipped on the printed circuit board so that the printed circuit part between the slits (U) cut in the printed circuit board will be left on the inside of the side walls (7, 7 min , 7 sec ) of the second part (1) and will bear on the inside grooves of the inner walls. The first part (2) and the second part (1) have locking means (3, 4) which lock the parts detachably to each other.

Abstract: The present invention is concerned with a device for preliminary crushing of a possibly clogged, material to be ground and for feeding of the said material into a jet mill containing a compressed flow of circulating grinding gas and material, so as to produce ultra-fineground admixtures to be used in industry. In prior art, exclusively ejector-type or injector-type feeder devices were used as feeder devices of jet mills of the said type, in which feeders the shifting of material into the pressurized mill takes place by means of the grinding gas. Besides their high energy consumption, another drawback of these prior-art feeder devices consists thereof that the grinding gas jet of the ejector, consisting of water vapour, sucks considerable quantities of air into the jet mill, along with the material, which causes a heterogeneous grinding result and makes the recovery of heat after the grinding difficult. In order to eliminate these drawbacks, a device in accordance with the above invention has been developed, which comprises a substantially vertical so-called plug pipe, which is at its upper end provided with a feeder funnel and which is at its bottom end, either directly or via an additional pipe, connected to the jet mill above the zone of the grinding gas nozzle. At the upper end of the plug pipe, preferably in its feeder funnel, at least one pushing means is provided which moves back and forth and which both crushes any clogged material and forces the crushed material as a tight plug through the pipe into the jet mill.

Abstract: A press fabric, for use on papermaking and similar machines, is of the open-ended variety, and has loops at each end enabling it to be closed into endless form during installation on the machine by means of a pin seam. The machine-direction (MD) yarns 1, from which the loops are formed during the flat or endless weaving of the fabric, are coated multifilaments. The coating 3, either permanent, semi-permanent, or soluble, gives the multifilament 2 a monofilament-like structure, enabling good loop formation and stability. The use of multifilament yarn provides a fabric having improved elasticity in the machine direction, and a greater degree of compressibility, following the removal of a soluble coating material, than can be obtained using monofilament yarn.

Filed: 1990-01-04
Granted: 1994-04-05
Abstract: ABSTRACT OF THE DISCLOSURE           In a data processing system in which each of the data processing units is implemented using pipeline techniques and has a cache memory unit employing a store through strategy, the time required to prepare a write instruction operand address can be substantially shorter than the time required by the execution unit to prepare the associated write instruction operand.  In order to utilize time difference, apparatus is included in the execution (E-)cache unit for storing the write instruction operand address during the preparation of the associated write instruction operand.  After storing the write instruction operand address, a next address is entered in an input register of the E-cache unit. When the newly entered address is associated with a read instruction, does not conflict with the write instruction operand address, and produces a "hit" signal when applied to the E-cache unit tag directory, the read instruction is processed by the E-cache unit.  When a second write instruction operand address is entered in the input register, the read instruction operand address conflicts with the stored write instruction operand address or the read instruction operand address results in a "miss" when applied to the E-cache tag directory unit, the address is stored in the input register until the write instruction operand has been determined and the associated  write  instruction  has been processed by the E-cache unit.

Abstract: Disclosed is a fastener system comprising a male or stud element with a split or bifurcated head, forming two prongs, that fit inside a female or socket sleeve.  Inside the socket sleeve is an internal annular ring of lesser diameter.  The stud prongs deflect when pushed in contact with the internal ring until the prongs pass the ring at which point they deflect out and lock into the sleeve.  This locking action allows for a variety of items to be clamped together along the length of the rivet sleeve providing that at each end there is a head of larger diameter than the sleeve.  This head can be replaced by any number of integrally molded items requiring a locking/mating action or where locking and rotation is desired.
