Title: High solids polyester resin-based coating  composition and method of making same
Inventor: LASHER EDWARD A
IPC: C09D167/08
Filed: 1979-04-25
Granted: 1982-08-24
Abstract: ABSTRACT OF THE DISCLOSURE           A low molecular weight polyester resin is made by condensation reaction of particular polyols and carboxylic acids, in a reaction mixture having excess hydroxyls and a system functionality between about 1.6 and 1.8.  In one embodiment, an aliphatic diol, a cyclic dicarboxylic acid and a monobasic fatty acid are condensation reacted together to produce the polyester resin, whereas in a second, and preferred, embodiment, the monobasic fatty acid is present as a hydroxyl-bearing, polyol-esterified oil or fatty acid.  The polyester resin of either embodiment can be cross-linked with an aminoplast resin, in the presence or absence of pigment,in a coating composition comprising 90% by weight and higher amount of solids to produce cured coatings exhibiting good hardness, flexibility, chemical resistance and gloss.  Pigment can be present in the cured coatings in amounts up to at least 60% by weight of the solids.

Abstract: 287-17.0l ECV:ls ABSTRACT OF THE DISCLOSURE           The gear drive from the hand wheel to the chain drum includes a worm wheel coaxial with the chain drum.  An idler shaft parallel to the plane of the worm wheel carries a worm engaging the worm wheel and a bevel gear.  The hand wheel shaft is parallel to the chain drum shaft and carries a bevel gear engaging the bevel gear on the idler shaft.  Between the worm wheel and the chain drum is a release mechanism which includes a release ring which when rotated about the axis of the chain drum is cammed to push a release plate into disengagement posi-tion.  This release ring has a gear segment thereon which is engaged by a gear segment on a release actuating lever.  In a modified embodiment this release lever also carries a cam which urges a brake shoe against a brake drum on the chain drum to apply a restraining force to the chain drum when the release mechanism is released.  There is also described a similar type of brake for chain drum drag on a conventional hand brake mechan-ism which utilizes only spur gears rather than a worm gear drive.

Granted: 1981-06-30
Abstract: A b s t r a c t The invention relates to a bed of the water bed type and com-prising a seat cushion or bed cushion having a support cushion (2) of an elastic foam plastic or foam rubber material which is enclosed in a water sealed and gas sealed bed tick (1) of a pliable but non-elastic material.  The length and the width of the support cushion is substantially the same as those of the bed tick whereas the height of the bed tick is larger, for instance 20 % larger than the height of the support cushion.  The support cushion is formed with several vertical through holes (5) having a cross section corresponding to a circle the diameter of which is 45 - 75 % of the height of the support cushion.  The water bed may be formed with side edges which are stiffer than the remaining portions of the bed or it may be immer-sed in a base plate having a frame (16) surrounding the entire water bed portion.  The water bed portion may be substantially less than the base plate (14) and the water may be secured in the base plate in that the sides (17) of the base plate in which the water bed is immersed are undercut and/or in that the water bed is formed with connection tongues (18) which are introduced in longitudinal slots (19) of the base plate.

Abstract: ABSTRACT OF THE DISCLOSURE        An improved yarn strand winding device and support cap adapter therefor comprising an end cap having an axial projection for insertion into the ends of a tubular yarn support carrier.  Mounted on the projection of the end cap is a resilient, radially expandable ring having internal surface portions matingly received about the projection with radial protrusions on the projections residing in corresponding recesses in the ring.  Upon initial rotation of a yarn support tube by peripheral engagement with a driving roller, the tube and rings of the end cap adapters move slightly relative to the main body of the cap to move the cap projections into engagement with surface portions of the ring and expand the ring against interior walls of the tube, thus ensuring positive grip of the tube to prevent improper transfer tail formation and provide proper yarn package build during yarn collection.

Abstract: Abstract A nuclear cardiology system (M) for use with a scintillation camera for evaluating cardiac function by real time measurement of the variation of radiation from the heart of a patient to whom is administered a radioactive tracer.  The camera (C) provides data describing the location of individual counts repre-senting radiation events coming from the patient. The system segregates, in real time, counts corre-sponding to radiation from an electronically defined region of interest (30) describing an investigated part of the heart, such as the left ventricle. Synchronized by the patient's electrocardiogram, (20) time gated memory circuitry divides each heart-beat into a series of subintervals, and stores indications of the respective amounts of radiation events emanating from the region of interest during each of the subintervals.  Calculating circuitry (32, 40) scans the stored information and, based on the maximum and minimum respective radiation amounts detected in the subintervals, computes the fraction of blood ejected by the heart in each beat. A strip chart recorder (12) provides a permanent representation of the curve of radiation from the region of interest, as defined by the indicated series of subinterval radiation amounts.

The process com-prises coating both sides of the metal sole with adhesive, fixing the metal sole on a first of the slabs corresponding to the first injection so that the metal sole is at a distance from the last when the injection mould is closed and provides between the mould cavity of the first slab and the last a gap corresponding to the thickness of an insole of the footwear which insole is produced by the first injection, thereafter stripping said first slab and bringing into  facing relation to an exposed side of the metal sole a second of the slabs for injecting an outsole of the footwear which outsole will cover the exposed side of the metal sole.  The metal sole is fixed on the first slab by means of at least two withdrawable finger members which project into the mould cavity of the slab, the metal sole comprising at least two notches located in two opposed portions of its periphery, the distance between the finger members being slightly less than the distance between the two notches of the metal sole so that the metal sole can be set and positioned on the first slab by means of flexibility of the metal sole and by the hooking of the finger members in the notches.  The distance between the metal sole and the last is obtained by means of at least one  spacer pin which is fixed under a lower face of the last said pin projecting to an extent equal to the thickness of the insole produced by the first injection. And an injection mould for carrying out this process.

Abstract: Abstract Remote-cutting instrument formed by an inner tube rotating within an outer tube, in which an initial cutting point where portions of the tubes first come together during a cutting cycle is defined at the distal extremity of the sides of the tubes and cutting edges extend from this initial point longitudinally along the sides of the tubes.  The co acting side edges of the tubes diverge in the proximal direc-tion.  There are end cutting edges of circular form, defining cusp-shaped points.  Partial or total minisectomies (removal of the meniscal cartilage from the knee) are performed by an appropriately sized instrument inserted into the joint space by a needlelike puncture incision.  Discrete pieces of the meniscal cartilage are severed by rotation of the inner tube at speeds of the order of 200 rpm or below and the discrete pieces are transported away in succession through the inner tube under the influence of vacuum.
