A defect detection system is especially applicable to string type potatoes for removing the black spots and includes removing or sorting out potatoes with black spots. It includes a pair of line scanning cameras focused on opposite sides of a vertical on a common line, spaced above the conveyor belt to the height of the potato. Such opposite sight lines provide for effective sensing of leading or ...

An inspection method and apparatus for searching a fabric in strip form to find lump type and void type flaws on both faces of the fabric. Strobes and image pickup elements are arranged at opposite sides of the fabric in transportation. The strobes at one side of the fabric are caused to emit light, and the image pickup elements at the same side detect light reflected by the fabric while the image...

The lift-up hanging tab for plastics containers, e.g. as used for dispensing serum, medicines etc. is basically a one-piece plastics member which has a flat tab with at least one hole (4) through which it is connected by welding, gluing, riveting or the like on at least one attachement base (E) of the container. The tab is provided on at least one edge with an arcuate wing (2) which extends to for...

A cable mount for securing a bundle of cables to a mounting surface is integrally molded with a high strength releasable cable tie portion joined at its head to a surface mountable support plate by a flexible hinge adjacent a strap positioning and securing channel. Insertion of the tip of the strap of the cable tie portion into the channel automatically aligns the head of the cable tie to accept t...

This invention deals with viscosity improvers which are obtained through the use of a mixed catalyst system comprising a tertiary organo halide and a Lewis acid catalyst.

This invention relates to phenolic resin compositions containing propylene glycol mono methyl ether acetate as a solvent. It also relates to the use of these compositions in foundry binders.

The invention relates to the monitoring of the drilling operations of a well using a drill bit (5) mounted at the end of a drill string (4), which can be taken up by the travelling block (8) of a lifting gear installed in a derrick, in order to permit the addition or removal of members from the drill string. By measurement with the aid of sensors (23) associated with the lifting gear and connected...

The invention relates to the preparation of low-viscosity aqueous dispersions of glycerol esters of long-chain fatty acids by dispersing under mechanical agitation in the aqueous phase, wherein the starting material is constituted by soap-free glycerol esters having a content of less than 2% by weight of free glycerol esters, a content is set of 0.5-6% by weight of alkali soaps of long-chain fatty...

Foamed products are prepared by subjecting a crosslinked polymer such as an ethylene-carbon monoxide copolymer susceptible to heating by high frequency electromagnetic radiation such as microwave or radio frequency which has been imbibed or impregnated with a suitable mechanical or physical blowing agent such as a halogenated hydrocarbon to sufficient high frequency electromagnetic radiation to ca...

A method is provided for the preparation of stable aqeuous dispersions of non-solvated, un-neutralized, low amine, low acid number polymerized fatty acid polyamider resins. In the preferred method of this invention, a polymerized fatty acid polyamide resin which has been prepared so as to have a low acid and low amine number is liquefied by heating the polyamide resin to a temperature where it is ...

The selection of the proper solvent systems for polyalkylene carbonates which completely dissolve the polymer at high temperatures but are non-solvents at lower temperatures allows one to obtain discrete particles of the polymers suitable for many applications, processing and handling. The particle size can be controlled from about 30 to about 3000 microns in diameter.

A matching method and apparatus for the automatic cutting of patterned fabrics by an integrated marking and cutting system first defines matching points in each of the patterns of panels to be cut and digitizes these points so that the coordinates and respective identification codes for each of the points are recorded in a memory. Matching relationships are then defined for the matching points whi...

An aqueous alkaline dispersion of a rubbery graft or over polymerized copolymer of a diene and a vinyl pyridine on a polyacrylate seed (core or substrate), said acrylate polymer having a Tg of not above about -20 DEG C., desirably also containing a polybutadiene, and a water soluble, heat reactable phenolic resin, in certain amounts is useful in forming an adhesive for bonding glass fiber reinfor...
