2079818 9115358 PCTABS00007 The invention relates to a process for manufacturing a multi-layer, preferable twin-layer composite of a polystyrene foam film and a coextruded unfoamed film, especially for further processing into labels or mouldings making use of the shrinking capacity of the films, in which a polystyrene material is extruded together with nitrogen as the blowing agent and a pore form...

An electronic surveillance system includes a signal generator for generating a magnetic field, a signal receiver within the influence of the magnetic field, and a ferromagnetic marker adapted to pass in said field for detection. The signal receiver includes an arrangement for generating a non-rotating field at a first frequency, and a rotating field at a second frequency that is lower than the fir...

Methods, compositions and apparatus are provided for coating a substrate with a strongly adherent hydroxyapatite coating, which allows for ingrowth of natural bane and strong bonding between the coating and the substrate. The procedure provides for coating under conditions which form sticky particles which bind to the substrate to from a crystalline hydroxyapatite coating. The coating has particu...

An apparatus and method are disclosed for securing elastic to a flexible backing for use in catamenial pads. The apparatus includes means for feeding the backing sheet onto a first drum having a plurality of surface grooves formed therein. The backing sheet is pulled into each of the grooves such as by a vacuum. A strip of elastic is then placed across each of the grooves and anchored at its respe...

A two piece brush for dispensing and applying a material in gel form comprises a brush element having a plurality of bristles and an elongated handle pivotably secured to the brush element for movement from a position adjacent the brush element to a position substantially at right angles to the brush element. An opening is provided extending through the brush element to the bristles which aligns w...

The invention is a three dimensional sensing system which utilizes two flexibly located cameras for receiving and recording visual information with respect to a sensed object illuminated by a series of light planes. Each pixel of each image is converted to a digital word and the words are grouped into stripes, each stripe comprising contiguous pixels. One pixel of each stripe in one image is sele...

In a surgical gown belted by tie-strings, one of the tie-strings has one end secured to the gown and the other end releasably attached to a transfer card, and means is provided for adhesively but releasably securing the transfer card to the front of the gown.

The object of this patent is a new device to elastically join and separate the frames of the glasses to their rims. The innovative aspect of the device is essentially that it eliminates two glasses, joined respectively to the rim and to the extremity of the frames, and the screw pivot that makes up the current structure of many normal or elastic joints currently used to guarantee the elastic openi...
