Abstract: ENHANCED PRODUCTION OF PROTEINACEOUS MATERIALS IN        EUCARYOTIC CELLS          ABSTRACT OF THE DISCLOSURE           Disclosed is a method of enhancing expression of recombinant DNA in eucaryotic cells.  A tissue specific enhancer element obtained from the genome of an organism and active in a selected tissue type is combined with a transcriptionally com-petent transcription unit comprising a promoter and exons encoding for the proteinaceous material of interest (or its precursor).  This recombinant DNA is transfected into cells derived from the same tissue as the tissue in which the enhancer element normally functions to enhance expression of endogeneous DNA.  The resulting transformants express the exons of the transcription unit at high levels as the enhancer element increases the copy number of mRNA.  The enhancer element operates to increase transcription independent of its orientation and position provided it is located within an active region on the DNA, generally between about 1-10 kilobases (kb) from the 3' or 5' end of the transcription unit.

Abstract: Abstract:        The invention provides an improved method for producing cinnamoylanthranilic acid compounds having hydroxy and alkoxy substituents.  The method involves reacting a nuclear substituted benzaldehyde derivative with a 2-carboxy malonanilic acid and a cyclic amine.          The reaction is carried out in an inert solvent medium and the cyclic amine is employed in a molar ratio of about 2-10 moles per mole of substituted benzaldehyde derivative reactant or 2-carboxy malonanilic acid re-actant.  This produces a crystalline precipitate of a cyclic amine salt which can be separated and then treated with an acid reagent to yield the desired compound.

Title: Process for the production of cast iron with  spheroidal graphite
Inventor: BRANDENBERGER URS
IPC: C21C1/10

Granted: 1988-02-16
Abstract: Abstract PROCESS FOR THE PRODUCTION OF CAST IRON               WITH SPHEROIDAL GRAPHITE      There is disclosed the treatment of an iron melt with metallic magnesium so as to produce spheroidal graphite in the subsequently formed cast iron, which necessarily results in the formation of a slag which contains sulphur.  In order to stabilise the sulphur present in the slag, an additive is introduced which acts to prevent re-sulphurisation into the melt.  One example of an additive to be used includes CaSi alloy, whereby the sulphur content of the unstable compound (magnesium sulphide) present in the slag is converted into a stable compound, namely calcium sulphide.  Therefore, the sulphur in the compound magnesium sulphide that becomes free, in the case of fairly long standing time prior to casting, is prevented from going back into the melt and reacting there with the dissolved magnesium (intended for the spheroidal graphite production) and forming magnesium sulphide again.   By the effective "setting" of the sulphur in the slag itself, re-sulphurisation of the melt is effectively prevented.  The slag can remain on the melt surface for a longer time, thereby providing a heat-insulating effect, so that longer standing times are possible, which are required in some production techniques.

Abstract: ROUTING ADDRESS BIT SELECTION IN A PACKET SWITCHING NETWORK Abstract A multi-stage packet switching network (100) includes a plurality of packet switching nodes (110) each included in one stage of a sequence of stages (101, 102, 103) of the network.  Each node (101-1-x) of a stage (101) is connected to a stage bus (220-1) that indicates to the node "ith" stage in the sequence of stages it is a part of, i.e., where in the sequence of stages that node appears.  Each node includes circuitry (450) that responds to the information carried by the associated stage bus to select "ith" most significant bit (504) of the destination field (502) of a received packet (500) as the bit on the basis of whose value the packet is routed at the node.  On a circuit pack (200) that includes nodes of a plurality of stages, the first stage bus is connected to a register (250) whose contents are the number of the first stage of the pack in the sequence of stages.  Adders (210) interconnect the stage buses of sequential stages and act to increment by one the value carried by each sequential stages' stage bus.  FIG. 2.

Abstract: ABSTRACT OF THE DISCLOSURE A system for technique and accelerated reaction training of a person by a training program in which an array of lights is positioned visibly in front of the person, with each light signigying a different particular movement pattern to be executed by the person in a given amount of time.  A control system selectively energizes one light of the array at a time, signifying a particular movement pattern to be executed, in a sequence of lighting of the array of lights unknown to the person undertaking the training program.  In this program, the sequence of lighting of the array appears to be random, such that the person waits for an unknown light to be energized, and must then react in a measured time period with the particular movement pattern to be executed in response to that particular light. The control system is programmable to enter a different individual time period of response for each different light, and then times each individual time period of response. Additionally, an audible feedback is supplied to the person by an acoustic transducer which is activated by the control system at the end of each individual time period of response to audibly signal, such as by a beep, to the person the end thereof.  In a preferred embodiment, the control system is microprocessor programmed and operated.  The microprocessor is coupled to an address bus, a control bus, and a data bus, and each of the array of lights, as well as additioal controlled features said as a voice sythesizer which provides audible instructions, is coupled to and controlled by the microprocessor by signals issued on the address bus, the control bus, and the data bus.  The array of lights comprises an array of six lights arranged in top and bottom horizontal rows of three lights, with the top and bottom rows being aligned vertically with respect to each other. Moreover, the system is preferably constructed and provided in a portable carrying case, wherein the array of lights is mounted in the top portion of the carrying case, and the control system and programming keyboard therefor is located in the bottom portion.

A latch is provided in the input/output controllers which responds to the synchronizing signal by storing the condition of the priority lines and whether an interrupt is pending.  In response to a broadcast interrupt origin request instruction from a processing unit, all input/output channel controllers will respond at the same time but only the one with the priority interrupt for the requesting processing unit gives a non-zero response.
