METHOD AND APPARATUS FOR SENSING OR DETERMINING ONE OR MORE PROPERTIES OR THE IDENTITY OF A SAMPLE In the method and apparatus, optimum correlation between measured and known values of transmittance or reflectance determines the property or identity of a sample. Three or more discrete radiation components can be selected which are transmitted or reflected by relatively different amounts due to int...

Single and multiple porous media impingement type air filter elements are disposed in filter housings which provide access to the filter elements from top opening doors or plenums in the housing for service or repair of the elements. Housing sections defining the plenums are provided with mechanism to lift and swing the housing sections clear of the filter opening, and the housing sections are mov...

A hybrid non-transferred-arc plasma torch system (2) utilizes an arc plasma torch (4) whose hollow body (10) carries internally a cathode (11) aligned with a relatively small diameter nozzle (12) which functions under a created arc to issue and arc flame (19) through the nozzle (12) with a plasma gas (32) applied to the chamber (14) of the hollow body (10). An external anode (30) electrically isol...

A bottle mouth defect inspection apparatus having a ring-shaped light source for irradiating a ring-shaped bottle mouth portion to be inspected, a photo-electric conversion sensor for converting a reflected light from the bottle mouth portion into an electrical signal and an electronic processor for processing the electrical signal to thereby inspect the existence or not of defects on the bottle m...

An uncured polyurethane coating formed by applying polyurethane paint containing isocyanate prepolymer on a substrate is cured by a method which comprises applying a catalyst (cure accelerator) on the uncured polyurethane coating and subsequently exposing the polyurethane coating to a heating atmosphere of 60.degree. to 100.degree.C. By this method, the reaction of urethanation explosively proceed...

A pigmented thermoplastic polymer masterbatch composition comprises a polyester of melting point above 200.degree.C based on polyethylene terephthalate, a second polymer to plasticize the polyester/and pigment in an amount of at least 20 parts per 100 parts of composition.

Relative angular movement between two linear members is detected by shining light from a light source (11) through a triangular mask (12) in one member onto a mirror (10) in the other member and reflecting the image of the triangular mask onto a linear array of detectors (15). Movement between the two members causes different detectors in the array to be illuminated and the position and number of ...

A process for blow molding and fluorination of a hollow thermoplastic article includes bringing a blank to rest against the inside wall of the blow mold as a result of introducing an inert blow gas. An inert gas/reaction mixture is then introduced in the hollow article for fluorinating the inside surface of the hollow article. After the inside surface of the hollow article has cooled off, the iner...
