Granted: 1982-03-02
Abstract: Abstract A process is disclosed for the production of double-faced articles of clothing, particularly scarves and ties. Two pieces of fabric are sewn together along their edges by means of two seams situated at a distance from each other in such a way that their respective reverse sides face towards each other and their edges, folded inwards between the two seams, are in each case double.  The invention is characterised in that the two pieces of fabric are first interconnected by means of a first seam and then have their edge portions folded inwardly as far as permitted by the first seam, after which the second seam is stitched to interconnect the doubled over edges and cause them to lie tightly against each other.  The result is a simplification of procedure and more uniform product.

Title: Removal of suspended matter, dissolved organics,  and emulsions from effluents
Inventor: ALEXANDER DOUGLAS S
IPC: C02F1/54
Filed: 1979-07-11
Granted: 1982-08-17
Abstract: ABSTRACT OF THE DISCLOSURE         Contaminants such as suspended inorganic solids and many dissolved organic materials in low concentration and emulsified oils, are removed from water by addition to the water of a small but effective amount of a polymer emulsion such as SBR latex, and agitation.  The contaminants rapidly settle with the agglomerated particles from the latex to give a solid residue and clear, substantially clean supernatant water which can be readily removed.  The settling process may be accelerated by addition of a latex coagulant, such as calcium, magnesium, aluminum ions or polyionic polymers.          Sinking or floating agents may be used prior to coagulation, to ensure sinking or floating, as desired, of separated solids.

Abstract: TRUNNION AND          TRUNNION PACKING SLEEVE INSERT FOR ROTARY DRUM FILTER     Abstract A rotary drum filter used to form and wash a pulp mat in the paper making process has a cylindrical filter drum with trunnions at its opposite ends mounting the drum for rotation about a central axis.  One of the trunnions is hollow and is rotatably connected to an open end of a stationary vacuum pipe for draining filtrate from the drum during its rotation.  Packing material provides a fluid seal at the rotatable connection between the vacuum pipe and the hollow trunnion.  The hollow trunnion has an inner wall lined with a fiberglass reinforced plastic material.          An outer end portion of the inner wall is recessed to pro-vide a seat for a packing sleeve insert made of an abrasion-resistant material.  The inner surface of the packing sleeve insert provides a continuation of the lined inner surface of the hollow trunnion.  An outer flange collar of the insert is threadedly fastened to an outer end surface of the hollow trunnion to hold the insert in place.  When the packing sleeve insert wears out, it is removed from the trunnion and replaced with a new one.

Granted: 1982-06-22
Abstract: °              ABSTRACT OF THE DISCLOSURE In order to measure the temperature of the mid-span first stage rotor blade of a gas turbine engine, an optical pyrometer is mounted in the inner casing of the gas turbine engine and includes an elongated sight tube extending from the optical lens of the pyrometer and through the wall of the engine separating the inner casing from the rotor. The sight tube includes an array of spaced apertures extending therethrough in the vicinity of the optical lens, with each aperture extending at an acute angle to the longitudinal axis of the sight tube away from the optical lens.  Pres-surized air within the inner casing passes through the ar-ray of apertures and effectively forms a conically-shaped fluid screen for preventing smoke, dust, fumes, or other contaminants from contaminating the optical lens.  A sec-ondary fluid screen may be provided by mounting the free end of the sight tube in an enlarged opening in the wall of the engine casing, whereby a secondary, generally cylin-drical flow of air is developed for shielding the open end of the sight tube.  The upstream edge of the sight tube may project into the slow path of the combustion gases flowing to the rotor stage whereby such combustion gases will be deflected and directed around the circumference of the sight tube to further inhibit contaminants from entering the sight tube and contaminating the optical lens.
