Title: A high-gradient magnetic separator
Inventor: CHRISTENSEN ORLA
IPC: B03C1/02
Filed: 1983-03-11
Granted: 1986-08-21
Abstract: A high-gradient magnetic separator is provided for filtrating weakly magnetic particles from a fluid in which they are suspended. The fluid is caused to flow through a separation chamber arranged in a gap formed between a pair of opposed pole surfaces of a pair of separate permanent magnetic devices connected with a closed magnetic circuit which includes yoke members. The permanent magnetic devices generate a strong magnetic field in the gap, the magnetic field having a field direction substantially transverse to at least a portion of the flow path of the fluid through the separation chamber. The permanent magnetic devices each include at least one permanent magnetic member having a substantially linear demagnetization curve. A matrix of soft magnetic material is located in the separation chamber to create local magnetic gradients in the magnetic field. The matrix includes strands extending in planes substantially transverse to the magnetic field direction. A major portion of the matrix strands have an orientation transverse to the magnetic field direction and to the main flow direction of the fluid.

Title: Injection molding system having an insulation sleeve
Inventor: GELLERT JOBST ULRICH
IPC: B29C45/30
Filed: 1984-08-16
Granted: 1989-06-01
Abstract: This invention relates to an injection molding system of the type wherein a heated probe is centrally located in the hot runner passage. The probe has a pair of circumferentially spaced melt channels, each with an upstream portion which branch out from a common central inlet to a downstream portion along the outer surface of the probe. The probe is seated in a well in the cavity plate and a hollow cylindrical insulating sleeve is located between the downstream portion of the probe and the wall of the well. The outer surface of the probe and the inner surface of the insulating sleeve have longitudinally extending grooves which are aligned to form the downstream portions of the melt channels. The insulating sleeve is formed of a thermoplastic material with low thermal conductivity and a high melting temperature. In addition to insulating, the sleeve provides the advantage that it avoids the space between the probe and the well wall filling with melt which often results in problems on color changes and the degradation of the stagnant material which is trapped.

Abstract: A monolithic integrated circuit chip preferably includes a pair of data busses capable of conducting in parallel the number of signals which can be processed simultaneously by the components on the chip. Signals on the busses are carried in a time-multiplexed manner, each bus having a pred. etermined number of time slots. Preferably, each component on the chip is connected to one or both of the busses and is assigned a particular time slot for the bus to which it is connected. The resulting chip is of a structured, rather than a custom, design. Accordingly, it can be readily expanded or contracted in the number of signals which can be simultaneously processed. The number of components which can be included on the chip is limited only by the number of time slots available on the bus to which it is connected. By providing two busses, such common circuit elements as two-input adaer subtracters can be readily accommodated by a chip designed according to the instant invention. The bit-slice organization of the chip significantly reduces the design effort of the components connected to a bus, since a one-bit slice is merely replicated for each conductor of the bus. Ease of expansion along this dimension is achieved at virtually no cost.

Abstract: Cellulose acetate butyrate gas separation membranes are prepared from a casting solution containing from about 10 to 30 percent polymer, 35 to 70 percent solvent, and 15 to 30 percent pore-forming agents. A film casting solution is cast onto a substantially flat support surface and a dense layer is formed on the exposed film surface. The film is gelled, washed, and dried to produce a particularly useful gas separation membrane. The cellulose acetate polymers used in this preparation have molecular weights of at least about 20,000, and have about 10 to about 45% butyryl groups, about 2 to about 35% acetyl groups, and about 0.8 to about 2 percent hydroxyl groups, by weight. The membranes may be used for separating a feed gas into a permeate fraction and a residual fraction, and are particularly useful for separating gases in the purge gas stream of ammonia plants to recover a permeate which is relatively rich in hydrogen. Cellulose acetate butyrate membranes may be used to improve the separation of ammonia plant purge gases which contain ammonia as well as hydrogen and nitrogen, especially when there is no pretreatment of the purge gas to remove ammonia gas.

Abstract: To permit safe writing of the pointer (P) pointing to the current record in a cyclic memory or ring memory, e.g. an EEPROM, the new record (D'#3) is written to the memory location (R3) containing the oldest record, and then the pointer (P) is updated. The pointer (P) consists of a first pointer (P1, P1*) and a second pointer (P2, P2*) redundant with respect to the first pointer. Each pointer contains a check value in the form of the inverse or complement code of the actual pointer. Due to the second pointer and the check value, the pointer is written with optimal safety. In case of a disturbance in the course of pointer updating, the old first pointer can later alternatively be recovered from the second pointer or the second pointer updated with the aid of the new first pointer.
