PURPOSE:To efficiently form base plates in possession of protruded parts and recessed parts without producing any waste of the material by forming the protruded parts on one side of edges of the base plate, and the recessed parts on the other side of the edges are put opposite to one another in the same shape and the same size. CONSTITUTION:Plural sheets of electrode base plate 1 are made by die c...

A product line is provided for forming a sheet product composed of products such as bacon slices resting on a pre-cut thin substrate such as a sheet of paper. The substrate sheets are pre-cut to a predetermined length, and a flow of individual products and a flow of pre-cut sheets are coordinated such that the products deposit onto the pre-cut sheets in a predetermined pattern. The line may also i...

Film dispenser for the strip-wise covering of surfaces, especially automobile windows, in which the film running off a supply roll is guided past a wetting strip of absorbent material and guided over a circumferential part of a pressure roll and applied to the surface without bubbles by moving the film dispenser. The injection moulded plastics housing has a labyrinthine dosing device for feeding a...

A splicing apparatus for spun yarns comprises a splicing member which has a cylindrical splicing hole, a slit for insertion of the yarns and a jet nozzle jetting a compressed fluid and opened to the splicing hole in the tangential directions, and yarn end control nozzles, yarn cutting devices, a yarn guiding means and yarn clamping devices, which are arranged in sequence on both sides of the splic...

1. High speed compression bandage consisting of a film (1) for covering and protecting a wound with a bloodsealing torus (2) located on the film, as well as fastening means (3) connected to the film, characterized in that the film (1) and the torus (2) constructed as a pressure ring are made in one piece from the same rubber-elastic plastic, the torus (2) having an acute (5) cross-sectional shape ...

Novel, multiple-tritiated steroid-20,17- spirolactones of general Formula 1 wherein -A-B is -CH2-CH2-, -CH=CH- or and R is hydrogen or tritium and n is 0 or 1, are usable as tracer materials for the detection of mineralocorticoid receptors.

PURPOSE:To recover quickly a trouble by bracketing a trouble generated point in response to data from a scan-out means. CONSTITUTION:Test data is scanned in to a shift register S-Reg, and a control line 5 is set to ''0'', and a required number of shift pulses are generated on a line 2 to circulate once data in the register S-Reg through a shift loop. If a fixed trouble exists in a logic circuit FF...

PURPOSE:To detect runaway surely by providing plural check points in a memory area where contents of data are executed by the detecting method using a watching timer, and resetting the watching timer after passing these check points. CONSTITUTION:If a periodic interrupt IRT for resetting a watchdog timer WDT is generated at a certain time, the processing of a check point 1(CP1) is performed first....

A method and apparatus for the determination of the concentration of certain chemical substances such as glucose, urea, enzymes, etc. in biological solutions such as blood, serum, urine, using a technique of differential pH measurement using two pH electrodes, and measuring pH changes in the solutions after the addition of specific reagents, the concentration being determined according to the form...

In order to avoid producing any secondary waste in the production of a fibrous and a granular material from household, agricultural, forestry waste, organic waste of the manufacturing and/or service industries, the primary waste first undergoes an opening treatment in an opening unit and then, after removal of any metallic components by magnetic separation units, is divided into three fractions. S...

A flexible polyurethane foam article with regions of different hardness is made by introducing into a mould a foam formulation giving a foam of a given hardness and then introducing a foam formulation giving a foam of different hardness directly into the first foam formulation at a time corresponding to a volume expansion in the range 100% to 2300%.

In this case, one or more light sources of a specific wavelength are used in a known way to illuminate a selected section of the material layer, the reflected light is recorded by a camera, and the signal thus obtained is evaluated, in order, e.g. to determine flaws. This method is improved by selecting a specific wavelength of the light source that is tuned to the surface to be monitored and the ...

1. A process of bonding one face (31) of a first body of rubber (3) to one face of a second body of rubber (1) which consists of a) applying said face (31) of the first body (3) to said face of a second body (1) with interpositioning of a connecting layer (2) of vulcanizable rubber, b) evacuating gaseous inclusions imprisoned between the rubber bodies [(3) and (1)] and/or resulting from a subseque...

The fleece web (60) to be patterned is guided past a first treatment station (36-38, 64) between a perforated supporting member (40) and a perforated drum casing (30, 33). At the same time, by being subjected to fluid, the fleece web (60) is provided with a first pattern, in that the fibres are ordered by the specific position of the perforation of the member (40) and of the casing (30, 33) in ord...

Resilient foam particles and moldings are obtained employing a lightly crosslinked polymer such as a styrene polymer with volatile fluid foaming agent that has low permeability through the polymer. Multiple expansion will permit low density particles for molding.
