Fibrous polyolefin nonwoven sheets are bonded and stretched in a continuous, multiple stage process. First, the sheet is heated without significant stretching to a temperature that is close to, but below, the melting temperature of the polyolefin. Then, as the sheet is forwarded to a first stretching stage, the sheet temperature is decreased by 5 DEG to 40 DEG C. and thereafter the sheet is alte...

Apparatus and method for preparing cooked crabs for further processing to separate meat from shell by centrifugal action is disclosed. The apparatus comprises a holding means (28), cooperating with a clamping means (190, 192) for securing a crab body (30) to a conveying means (20). The conveying means (20) moves the crab body (30) which has had the carapace shell removed along a predetermined path...

The surface texture of a moving transparent film is determined by applying a beam of collimated electromagnetic radiation at an angle of incidence sufficient to produce detectable backscattered radiation; collecting the backscattered electromagnetic radiation while avoiding specularly reflected radiation; and evaluating the intensity of the collected radiation for two components, a first component...

A method and apparatus for the on-line determination of the bonding strength of a plural layer laminate having at least one outer layer transparent to electromagnetic radiation, said method comprising: directing a collimated beam of electromagnetic radiation onto the substantially flat surface of said laminate at an incident angle substantially greater than a normal to the surface of said laminate...

Spray dried detergent granules containing high levels of certain surfactants are compacted under certain conditions and admixed with other ingredients to form dense, rapidly dissolving detergent compositions.

1. Process for the production of an assembly adhesive seal, characterized in that a second adhesive sealing composition based on urethane prepolymers having free NCO groups is applied to a first adhesive sealing composition based on polyurethanes which has been applied to a pane which is to be assembled, the surface of said first adhesive sealing composition having been treated after shaping and b...

The present invention provides a device and method for protecting, by means of a casing, a measuring instrument or a specialzied tool fixed to the end of a drill string. Said drill string has substantially at is end and before said tool a first guide member and said casing has a second guide member, said first and second guide member being adapted for cooperating together so as to allow movement o...

The invention relates to a hydrodynamic retarder having two independent operating circuits. Opposite a double rotor on the one hand is a stator fixed to a housing, and the rows of vanes concerned are inclined. The other half of the rotor forms with a rotatable stator and a second operating circuit having rows of blades equally effective in both rotational directions. The stator of this second oper...

Linear low density copolymers (LLDPE) are blended with up to about 10 weight percent of an aromatic polymer, e.g., polystyrene or poly(para-methylstyrene), to give films having improved MD tear strength or equivalent MD tear strength and higher stiffness compared to the LLDPE alone. Also, extruder torque is lower and bubble stability is greater in blown film extrusion with the blends as well as in...

In a color image sensor, CCD chips having peculiar spectrum distribution characteristics are arranged in two rows on a base with the CCD chips in one row staggered with respect to those in the other row. A pair of convergent rod lens arrays is located between a color document and the array of CCD chips for projecting an image of the document onto the CCD element array. The CCD elements each having...

A recording disc comprises a substrate having a tracking servo groove of spiral or concentric pattern on one surface thereof. The servo groove has a constant depth and a variable width which varies to allow generation of a position indicating signal. An eraseable recording layer is deposited on the surface of the substrate to store information signals. The recording disc is fabricated by a method ...

Borate Solution Soluble Polyvinyl Alcohol Films Conventional polyvinyl alcohol envelopes will not readily dissolve in wash water which has a significant borate concentration and a pH frequently encountered in wash liquors. Herein, such films are rendered sufficiently soluble in such solutions. In the preferred embodiment this is done by utilizing a polyvinyl alcohol film wherein at least a portion...

HIGH IMPACT STRENGTH FIBER RESIN MATRIX COMPOSITES Improved fiber resin matrix prepreg fabrics are disclosed which are comprised of a first layer of reinforcing fabric coated with an epoxy resin composition and a discrete second layer of an epoxy resin modified with an elastomeric polymer. The discrete second layer is provided with a support comprising a gauze-like, lightweight fibrous mat or carr...

Multifilament bundles are impregnated with an ultraviolet curable resin to form a composite material suitable for use as a strength member in cables and other applications. The coating material is desirably a bisphenol-A-diglycidylether diacrylate resin and a diluent therefor. The inventive coatings obtain good wetting of the filaments, allowing rapid penetration into the roving or yarn. A much fa...

A method of rapidly dissolving particles of water soluble polymer gels in water. A suspension of gel particles is formed and subjected to conditions of high shear in a particle size reduction apparatus whereby finely sliced particles are formed and instantly dissolve in water. Sufficient water is present that heat is dissipated and molecular degradation of the polymer is avoided.

An improved mechanism for delivering motive power to the wheel-tire units on a land vehicle, comprising a differential having two operating modes, namely a "locked" mode and an "unlocked" mode. The unlocked mode is used when a tire is punctured; differences in tire diameter incident to tire puncture are effectively compensated. The locked mode is used when the vehicle is traversing slippery terrai...

An improved process for obtaining juice from fruit. The fruit is processed to provide a pumpable fluid puree of fruit and juice which is pumped at pressures in a range of from about 100 to about 1000 pounds per square inch in a single pass through a rigid porous tubular housing having a diameter of from about 5/8 inch to about six inches and having a food grade ultrafiltration membrane deposited o...

A drilling template for accurately positioning latch holes and lock cutouts in door stiles. The template includes a pair of spaced, parallel, rectangular, frame member that are rigidly interconnected at one end. The frame members straddle a vertical door stile with the interconnecting end firmly against the edge of the stile. Clamps on one frame member are then tightened. A latch hole drilling gui...
