1. Process for producing a spiral-shaped flat coil (4) for a shock wave tube, characterized in that a mask in the form of a spiral is photographically transmitted on to a printed circuit board (9) having a supporting layer (11), with an electroconductive layer (13) lying thereabove and a light-sensitive top layer (15), in that the top layer (15) is developed, in that the spaces between the spiral ...

A shock wave tube has a coil carrier, an isolating foil, and a diaphragm. The diaphragm is made of a bronze alloy, preferably beryllium bronze. The diaphragm is silvered on the side facing the coil carrier. The coil carrier is made of an aluminum oxide ceramic. Advantages deriving from the use of the materials are long life, substantially constant technical parameters and good reproducability of t...

A modular multi-channel automated medical analyzer device is disclosed, characterized by use of an ion selective electrode and/or enzymatic electrode/wash cell system which permits rapid analysis of various substances of interest contained within undiluted body fluids such as whole blood, serum and/or plasma. The ion selective electrode and/or the enzymatic electrode are disposed upon a probe whic...

An entangled composite fabric having a sharply delineated pattern on the upper surface, and a method for producing same without any additional off-line finishing step. The fabric of the invention has the feel of a soft linen.

An aqueous phenol formaldehyde resole, suitable for use in the manufacture of phenolic foam insulation, has a molar ratio of formaldehyde to phenol in the range of from about 1.7:1 to about 2.3:1, and a weight average molecular weight greater than 800. Preferably, the resole also has a number average molecular weight greater than 350 and a dispersivity greater than about 1.7. Phenol formaldehyde r...

A foamable phenolic resole composition is foamed and cured with an acid curing agent which is an anhydrous aryl sulfonic acid which has a pKa of less than about 2.0 and which reduces the compatibility of the resole with water, e.g. benzene, toluene or xylene sulfonic acids. The phenolic foam formed has cell walls which are substantially free of perforations. The preferred anhydrous aryl sulfonic a...

PURPOSE:To recover granular vinyl chloride resin suitable for processing into a paste, by passing an aqueous dispersion of vinyl chloride resin through a screen having a specific screen opening, mixing a special organic liquid with the resultant aqueous dispersion, forming an aggregate and treating the resultant aggregate. CONSTITUTION:(A) An aqueous dispersion of vinyl chloride resin is passed th...

A heat resistant precoated steel sheet suitable for use in the manufacture of a muffler of an automobile exhaust gas system comprising: a hot dip aluminized steel sheet, a chromate pretreatment layer formed on at least one surface of said hot dip aluminized steel sheet and having a chromium pickup of 10 to 50 mg/m2, a primer coat formed on said pretreatment layer and comprising a cured polyamide i...

The magnet frame of a dynamoelectric machine comprises a removable, generally cylindrical inner member concentrically disposed inside a cylindrical outer member. The inner member is supported in a cantilever fashion at only one of its ends, and most of its outside surface is normally separated by a relatively small circumferential gap from the cooperating inside surface of the outer member. The ou...

A process for preparing collagen tubes includes extruding an aqueous gel containing about 1.5% native collagen through a cylindrical spinneret equipped with a central concentric tube designed to receive a part of a coagulation bath, followed by coagulation of the internal and external walls of the tube, leaving the spinneret in a coagulation bath constituted by about 70% acetone and 30% ammonia, f...

L'INVENTION CONCERNE UN PROCEDE D'OXYDATION DE SUBSTANCES DISSOUTES OU EN SUSPENSION DANS UNE SOLUTION AQUEUSE.

SELON LE PROCEDE, ON INJECTE A L'ENTREE D'UN REACTEUR TUBULAIRE POLYPHASIQUE 6, D'UNE PART LA SOLUTION AQUEUSE A UNE TEMPERATURE TELLE QUE LA REACTION D'OXYDATION S'EFFECTUE A UNE TEMPERATURE COMPRISE ENTRE 70C ET 370C ET A UNE PRESSION ABSOLUE PE COMPRISE ENTRE 5 BARS ET 210 BA...

It is constituted by a wrapping made of a semi-rigid synthetic material 1 not covering the corpse but with a bottom forming a collector and ends 7, 8 fulfilling functional capacities avoiding any spilling however the coffin is tilted. The aim is to avoid the drawbacks of the plastic cover which encloses the deceased in certain districts and which by its airtight nature slows down normal decomposit...
