An animal control device for prohibiting animal access to or egress from a desired area. The transmitter comprises a flexible transmitter strip and strip extensions that are designed to be physically unobtrusive. The strip further comprises on/off switch, frequency control, AC power plug and a battery backup. The receiver and emission component of the device comprises a removable and adjustable animal collar, or plurality of animal collars which emit audible sound, ultrasound, vibration, or mild electric shock.

Animal control device

An automatic animal feeder includes a housing has a top wall, a bottom wall and a peripheral wall having an opening therein. A plurality of food delivery assemblies is positioned in the opening. Each of the food delivery assemblies includes a food drawer slidably positioned in the opening. The drawer is selectively extended inwardly or outwardly of the housing when a rod threadably coupled thereto is rotated. A motor is mechanically coupled to the driving rod. A processor is mounted in the housing and is electrically coupled to each of the food delivery assemblies for selectively turning on the motors. A first time control is electrically coupled to the processor for selectively inputting a time and date when each of a selected one of the food trays will be extended outwardly from the housing. A cooling assembly is mounted in the housing for selectively cooling an interior of the housing.

Process for the purification of caprolactam obtained from the depolymerization of polyamide-containing carpet

The present invention provides a process for the preparation of purified caprolactam comprising the steps of:

Process for the purification of caprolactam obtained from the

A process for recovering monomer from multi-component waste material that includes a hydrolyzable polymer, includes contacting the multi-component waste material with water and subjecting the resulting mixture to heat and pressure to form a liquid aqueous portion and a water insoluble portion. The liquid aqueous portion mainly includes depolymerization products of the hydrolyzable polymer, and the water insoluble portion mainly includes components other than the depolymerization products. This mixture is cooled and the liquid aqueous portion and the water insoluble portion are separated. Monomer that formed the hydrolyzable polymer is recovered from the liquid aqueous solution.

Monomer recovery from multi-component materials

Useful fertilizer solutions of high nitrogen and high sulfur content can be prepared from ammonium sulfate, ammonium nitrate and urea in water. By selecting proper ratios, low salt-out temperatures can be achieved to use optimum amounts of inexpensive urea.

Solutions of ammonium sulfate, ammonium nitrate and urea, with high

This invention is a method to recover caprolactam from a combined stream of mother liquor from a caprolactam crystallizer and other lactam containing aqueous streams, the improvement comprising steam distilling the combined stream at a temperature of from between about 180.degree. C. to 235.degree. C. in the absence of any depolymerization agent such as phosphoric acid; so that the residue from the steam distilling remains fluid; relatively low levels of caprolactam remain in the residue; less residue is generated; the recovered caprolactam has improved high quality; and losses of caprolactam due to side reactions are reduced.

A flame-retardant pile carpet having a relatively pliable primary backing and a tufted surface, said surface being comprised of fibers selected from the group consisting of polyester and polyamide fibers having incorporated therein from 0.1 to 15 percent by weight of a compound selected from the group consisting of zinc oxide and zinc hydroxide, said fibers being bonded to said backing with a bonding substance comprising a latex material and a hydrate material, said latex material being selected from the group consisting of polymers and copolymers of vinylidene chloride, and said hydrate material being selected from the group consisting of aluminum hydroxide and hydrated aluminum oxide, the ratio by weight of said latex material to said hydrate material being within the range 1:2 to 1:4.5.

Flame retardant carpet

A flame-retardant polyamide fiber is prepared and made into a flame-retardant carpet. The polyamide fiber has incorporated therein from 1 to 15 percent by weight of zinc borate and from 1 to 15 percent of an organic halide which is substantially non-reactive with the polyamide except at temperatures above 300.degree. C. The flame-retardant fiber shows improved luster and improved colorfastness to light when dyed.

Flame-retardant polyamide fiber for use in carpets

A flame-retardant pile carpet having a relatively pliable primary backing and a tufted surface, said surface being comprised of fibers selected from the group consisting of polyester and polyamide fibers having incorporated therein from 0.05 to 15 percent by weight of a compound selected from the group consisting of antimony oxide and zinc borate, said fibers being bonded to said backing with a bonding substance comprising a latex material and a hydrate material, said latex material being selected from the group consisting of polymers and copolymers of vinyl chloride and vinylidene chloride, and said hydrate material being selected from the group consisting of aluminum hydroxide and hydrated aluminum oxide, the ratio by weight of said latex material to said hydrate material being within the range 1:2 to 1:4.5.
