Abstract: ABSTRACT It is known to produce electrolysis metal coated steel strip by a method comprising pickling a hot-rolled steel strip, rinsing a first time and cold-rolling, and thereupon cleaning, rinsing a second time, tightly coiling, annealing and thereupon skin passing, upon which the strip is electrolytically coated.  In this invention, during the cleaning operation the strip is first passed through a dip bath, after brushing then through an electrolysis bath, in which known saponifying, emul-sifying and suspension forming compounds are added to the bath liquids, whereupon the so cleaned strip after brushing and rinsing is passed through a (second) conditioning bath, in which there is added to the bath liquid between 10 and 5000 ppm of a substance which under annealing conditions blocks at least one of the above-described surface reactions causing graphitisation and which because of its electronic configua-tion (sp- or d- configuration) adsorbs preferentially to the active metal surface.  This produces strip free from surface graphite.

Abstract: ABSTRACT OF THE DISCLOSURE           This disclosure relates to a multi-microprocessor unit which is adapted for implementation in a single MOS semiconductor chip, which unit includes a plurality of sets of registers where each set represents a different processor.  The unit further includes common elements which are shared by the different sets of registers in a time multiplex manner.  The shared elements include two scratch pad memories, an arithmetic logic unit, and a control unit which incorporates a composite read only memory from which control signals are fetched to initiate the respective data transfers and arithmetic operations.  This control memory acts as a decoder for encoded microinstructions retrieved from outside of the multi-processor unit.  In this sense, the present invention employs both vertical and horizontal microprogramming as these terms are conventionally defined. The different sets of dedicated registers are formed of 4-bit shift registers so as to permit a four-way time slicing among the processors.

Title: Method of automatically assembling and mounting contacts in plug-type connectors, and connectors produced according to the method
Inventor: BAUERLE GERHARD
IPC: H01R24/00
Filed: 1976-04-08
Granted: 1979-12-04
Abstract: ABSTRACT OF THE DISCLOSURE            The present invention relates to a method of auto-matically assembling and mounting contacts in plug-type connectors, with the plug-type connector consisting of a housing and a strip made of insulating material,  which strip can be joined with the housing and which supports the contacts.  In addition, the present invention relates to connectors produced according to the method.  With prior art connectors of this general type, the contacts have been embedded in the insulating strip in a heat treatment process, e.g., by thermoplastic coating or with an ultrasonic welding technique.  The heat treatment processes which can be used are relatiaely expensive and can be executed only with the aid of costly machinery, requires much time, and con-tacts are coated with a plastic film at least at contact sections protruding from the insulating strip, which means that the contacts must subsequently be cleaned.  The present invention overcomes these disadvantages by providing a web material as a band-like strip of insulating  material into which the contacts are mechanically embedded.  The housing is joined with the strip of insulating material and sections of a desired length are separated from the band-like insu-lating strip only during the final assembly stage in which said insulating strip is joined with said housing.

Abstract: Abstract of the Disclosure Conducting cermets with volume fractions of metal down to 0.045 are produced by coating relatively coarse refractory oxide granules with fine metal powder particles and compacting and sintering the coated granules.  Using oxide granules in the size range 400 to 800 microns it is possible to make conducting cermets having the same volume fraction of metal and thus the same thermal expansion coefficients as insulating cermets prepared from finer granules of the same oxide.  The cermets can be used to fabricate tubes and components for electric lamps and may include integrally formed conducting and insulating regions.

Abstract: OVERSIZED DATA DETECTION HARDWARE FOR DATA PROCESSORS       WHICH STORE DATA AT VARIABLE LENGTH DESTINATIONS          Abstract of the Disclosure Size exception detection hardware for use with a digital data processor arithmetic unit for providing high-speed detection of lost data which results from storing an arithmetic result in a destination which is smaller than one or both of the source operands.  In response to data processing machine instructions, the arithmetic unit performs arithmetic operations on variable length operands and sends the arithmetic results to variable length destinations. The operand and destination lengths are specified by length fields in the machine instruction.  The destination length is specified independently of at least one of the operand lengths and hence may be less than such operand length. The size exception detection hardware looks at both the output field of the arithmetic unit and the destination length field in the machine instruction and generates a size exception program interrupt signal when the part of the arith-metic unit output field located outside of the destination length contains significant data.  The size exception interrupt is generated during the same machine control cycle during which the arithmetic unit performs the arithmetic operation  which gives rise to the size exception.

Abstract: ABSTRACT           A sample of material to be analyzed is applied in a thin layer to a substrate such as an elongated tape and then is illuminated by a laser beam of such wavelength and power that at least a portion of the sample is vapourized.          The substrate is non-absorptive at the laser wavelength and therefore is unaffected by the laser beam.  The vapourized matter is removed from the region at which vapourization takes place, and is subsequently excited in a plasma to facilitate analysis by a conventional spectrometer.

Abstract: LOGIC CONTROL FOR ELECTRONIC  KEY TELEPHONE LINE CIRCUIT     Abstract of the Disclosure An electronic key telephone line circuit is dis-closed for controlling the hold and disconnect conditions with respect to associated telephone stations in response to transient signals generated upon on-hook to off-hook and off-hook to on-hook transitions of those stations.  Due to the nature of the switchhook contacts, the tip and ring leads open before the A-lead opens.  Since the disconnect condition is determined from a transient signal caused by the tip and ring lead opening together with an A-lead open, and since by its very nature the transient response of the tip and ring lead transition can be finished before the A-lead opens, timing is used to delay the transient signal to insure that the line circuit goes into the proper mode.
