A techniqu for producing measurements of physical characteristics of subsurface media near a borehole penetrating the earth is disclosed that uses multiple transducers positioned along a borehole tool. A number of transducers of a first type, such as transmitters, are separated from each other along the tool by a preselected separation, and a number of transducers of a second type, such as recei...

The inner ends of cover-supporting ribs of an umbrella are pivotally connected to a rib carrier which is longitudinally slidable in a hollow shaft by means of a handle extending out through a longitudinal slot in the shaft. The rib carrier is slidable by means of the handle between a closed position in which the rib carrier is near the lower end of the shaft and the rib members together with the c...

A plant to extract meat from small crustacea, specially antarctic shrimps (Kril) consists of a mechanism to crush the carapaces, one for sepg. any readily floating particles, and one for sepg. the meat. A liq. is used to flush away the floats and the sinks are taken by an ejector to the meat separator. - This system has a higher productivity and a better meat yield than conventional methods.

A dispensing gun for fluids such as urethane foam and the like is provided in which separate fluid components are individually led to the gun and are mixed within a replaceable mixing and dispensing nozzle member. After gun use, the used nozzle member can be removed for cleaning or replacement with a fresh nozzle, thereby obviating difficulties encountered in cleaning and purging the entire gun. A...

A process is provided for mechanically surface-finishing a textile fabric which comprises ccontinuously feeding said fabric from a source of supply, such that said fabric lies in a single plane, subjecting successive adjacent sections of the fabric to intermittent mechanical impact with an abrasive means across the width of said fabric thereby avoiding substantial sustained contact between the fab...

A laser control device (4) includes a pulse repetition interval timer (4d) and a pulse width timer (4b) that, upon each setting, directs one pulse having a predetermined pulse width to a laser system (5) that emits a laser beam in response thereto. A pulse cycle timer (42) is provided which sets the pulse width timer at preset intervals during a time period from its initial setting until the reset...

Method for detecting flaws in coatings such as, e.g., dust particles, so-called sags or wetting flaws on a surface of a coating, preferably a surface of a coating in the automotive industry. The surface of the coating is irradiated by a fluorescent tube in such a way that a mirror image of the fluorescent tube is produced by the surface of the coating. In addition to the mirror image of the fluore...

An automatically controlled vehicle eg a bulldozer, mower or sprinkler truck has a distance sensor for detecting the vehicle running distance, an orientation sensor 5 for detecting the running direction thereof, and a processing unit for teaching the running course of, one travel of the vehicle by sampling the running direction detected by the orientation sensor every predetermined running distanc...

An edible suspension of a finely divided food material in a liquid suspending medium which swells cellulose, the suspension also containing microfibrillated cellulose in an amount sufficient to produce a stable, homogeneous suspension. The microfibrillated cellulose, a form of cellulose having a very large available surface area per unit of weight, acts to confer, among other benefits, greater sta...

The invention relates to a method wherein uncured urethane formulations are bonded to a cured rubber or synthetic rubber substrate in such a manner so as to provide greater bonding strength than has been achieved previously in urethane formulation bonding to rubber or synthetic rubber. The substrate is cleaned, a coating of a cyanoacrylate adhesive is applied, followed by a liquid or paste urethan...

This invention relates to a body of three-dimensional fabric, a method of producing such bodies or parts of various shapes from three-dimensional fabric and also relates to apparatus for industrial performance of this method.

A gas discharge display device has a discharge chamber and a post-acceleration chamber which are separated by a perforated control disc having line and column conductors thereon. The post-acceleration chamber is limited at its lateral boundary by at least one spacing frame which leaves the post-acceleration chamber support-free in its active volume. The inner boundary of the lateral spacing frame ...

In the manufacture of bodies of foamed plastic material, a polymeric synthetic resin base material is mixed with a cross-linking agent, a foaming agent and at least one further additive.
