Patent CA-1280861-C (CA)
Inventor: GOTO FUMIO
IPC: B29C39/24
Filed: 1987-12-15
Granted: 1991-03-05
Abstract: Abstract Moldless process for manufacturing foamed arti-cles is disclosed wherein a trim cover is first prepared as having a composite structure of an outer surface material such as fabric and an inner backing material of low melting point such as a thin foam of polystyrene and having a shape substantially corresponding to a final contour of a fin-ished article to be obtained; the trim cover is heated and forced to form a pre-shaped cover conforming to the final contour of the finished article preferably by means of a restraining frame such as a basket or plastic cage config-ured to the final contour of the finished article: high reactive polyurethane composition foamable at low internal pressure then poured into the pre-shaped cover and allowed to foam and expand to fill substantially an entire volume of the pre-shaped cover; and then externally heating of the pre-shaped cover is conducted at or near temperatures of the melting point of the backing material so as to con-siderably shrink the backing material interposed between the surface material and the foaming polyurethane and cause the backing material to virtually disappear while allowing the polyurethane to further expand to adhere to and become integral with the inside of the surface material to thereby obtain an integrally foamed article without the use of the so called mold.

Title: Process for making expanded fiber
Inventor: VINSON KENNETH D
IPC: D21D1/38
Filed: 1987-12-18
Granted: 1992-09-29
Abstract: ABSTRACT     A process for making mechanically expanded fiber from fibrous material having a fibrillar ultrastructure. The expanded fiber is made by impacting the fibrous material with a plurality of fine media. Impacting by the fine media causes the fibers to expand from a fibrous form to a highly fibrillated form, wherein fibrils separate from, or become substantially dissassociated from, the fibrous material ultrastructure. Cellulosic fibrous material is particularly applicable to the process. Cellulosic fibrous material is preferably impacted with fine media at least until the cellulose-containing phase of an aqueous slurry containing 0.5%, by weight, of cellulosic material will retain at least fifty percent of the initial volume of such cellulose-containing phase upon unagitated settling for a period of sixty minutes.

Title: Hot melt adhesive applicator and temperature control circuit therefor
Inventor: DENNISON RICHARD L
IPC: H03K17/00
Filed: 1988-05-25
Granted: 1992-05-19
Abstract: Abstract of the Disclosure A hot melt adhesive applicator operable at a number of selected temperatures having a portion of the circuitry for control of the applicator temperature at a point remote from the applicator body. The remotely located circuitry employs a differential amplifier (39) and a zero crossing detector (38) for controlling the operation of a triac (41) which, when turned on, increases the temperature at the applicator. The differential amplifier (39) is protected by a clamping circuit (66-6n) from receiving a signal, when a temperature setting is changed from a high to a low setting, that would otherwise cause the differential amplifier (39) to provide an output required for turning on the triac (41) which would cause a run away condition to exist.

Abstract: ABSTRACT         A resistive  fault in an electrical cable is located by  applying  a  DC voltage  to one end of  the faulted cable conductor.  The steady state DC voltage and current are measured at the end of the conductor where the voltage is applied.   Simultaneously, the DC voltage is measured at the other end of the cable.  The voltage is  then  reversed  in  polarity  and  the measurements repeated.  Several repetitions of this procedure at each end of the conductor yields sufficient information to compute  the  location of  the  fault with reasonable accuracy.   The procedure  is  carried out using two computer-based units, one at each end of the cable, with the  two units  communicating over the conductor under test.

Granted: 1992-07-28
Abstract: Abstract of the Disclosure Enhanced telephone services are provided through a multi-service telephone switching system that contains a programmable adjunct connected to a telephone switching system.  Specifically, this system includes a telephone switch that serves at least one subscriber and an adjunct connected both through one or more distinct paths, such as a number of hunt group lines, and through a datalink, such as a simplified message desk datalink, to the telephone switch. The telephone switch routes a telephone call involving this subscriber to the adjunct through an available hunt group line and provides a message to the adjunct over the datalink specifying a condition under which the call was routed.  In response to this message, the adjunct takes complete control of the call substantially throughout the remainder of its duration and provides a desired enhanced service that has been pre-defined by a service script stored within the adjunct. Different service scripts can be invoked to provide correspondingly different enhanced services to the subscriber depending upon the specific condition for which the call was routed to the adjunct and/or a specific event occurring during the call.

Abstract: ABSTRACT OF THE DISCLOSURE         An acidic aqueous cleaner, preferably in micro-emulsion form, which is of a pH in the range of one to four and is useful for cleaning hard surfaced items, such as bathtubs, sinks, tiles and porcelains, and even some such items which are not acid resistant, such as those of a European enamel known as zirconium white enamel, comprises synthetic organic detergent, such as a mixture of anionic and nonionic detergents, e.g., sodium paraffin sulfonate, higher fatty alcohol ethoxylate sulfate and higher fatty alcohol or phenol ethoxylate, car-boxylic acid e.g., mixture of succinic, glutaric and adipic acids, and phosphonic acid, e.g., aminotris (methylenephos-phonic acid) in an aqueous medium.  Preferably a phosphoric acid is present to further improve protection of such European enamel surfaces.  The acidic cleaner is useful to remove soap scum, lime scale and grease from surfaces of the mentioned items without adversely affecting such surfaces, and removals of the scum, scale and grease is easy, being effected by applying the microemulsion to the surface to be cleaned, followed by wiping it off.  Although the cleaned surfaces may be rinsed that is not necessary and the surfaces will be left clean and shiny after wiping, even without rinsing, or with minimal rinsing.  In the described emulsions the carboxylic acid components effectively remove soap scum and lime scale, the detergents remove greasy soils and promote effective contact between the acid and the surfaces to be treated, and the combination of phosphoric and phosphonic acids prevents acidic attack of the dicarboxylic acids on the surface being cleaned, with the phosphoric acid increasing protective action of the phosphonic acid component.

Abstract: METHOD OF MAKING MULTI-FOCUS OPHTHALMIC LENS     ABSTRACT         A method of producing multifocal ophthalmic lenses having a near vision minor lens element adhesively secured to the ocular surface of a major lens is disclosed.  The ocular surface of the major lens is finished to provide an ophthalmic prescription lens.  This ocular surface may have a spherical, cylindrical, or prismatic curvature, or any combination thereof, and thus generally may have a complex toric curvature.  The minor lens has a predetermined "add power", to provide a near vision segment on the major lens, and preferably is flexible, or is made flexible as by heating, so that it can conform to the shape of the toric curve on the ocular surface of the major lens without distorition or change in its add power.  An adhesive material is placed on the major lens, and the minor lens is carefully positioned and gently pressed against it so that it conforms to the curvature of the major lens.

Abstract: A method and apparatus for testing wearing apparel that defines an enclosure for moisture vapor transmission.  Thin, flexible, waterproof liners which have a high permeability to moisture vapor are inserted into the interior of the apparel and filled with water.  The water may be heated to simulate body temperatures and to produce higher concentrations of moisture vapor inside the apparel article.  The amount of moisture transferred to the external environment of the apparel article, as well as the amount of moisture absorbed and condensed in the apparel article itself, can be measured by the weight differences which occur over a test period.  The method is non-destructive and suitable for quality control, as well as for new product design.
