Abstract: An electronic safety baton for providing a portable, multifunction security apparatus which includes both visual and audible interface is embodied as a baton housing that externally includes a lighting element, a speaker, a display screen, pulse sensors, two manual actuators, and a baton charging surface, internally includes a rechargeable battery, and utilizes a discrete floor charger mat. The electrically interconnected components on and in the baton housing enable a pulse reading system, a lighting system, and a panic system, each of which use electricity from the battery and are activated through manual engagement. The baton charging surface, when engaged with the floor charger mat, enables the recharging of the battery by allowing externally sourced electricity to be directed to the battery.

Abstract: An apparatus for teaching an individual proper body rotation when striking a ball is disclosed which includes an elongated body member having a first end portion, a medial portion and a second end portion. A strap is connected to the elongated body member for securing the elongated body member in a is substantially horizontally disposed position on a portion of a lower lumbar region of the individual's back whereby at least a portion of the medial portion and the second end portion of the elongated body member extends outwardly from the individual. Upon the individual assuming a ball striking position and simulating a swing or a ball striking motion, at least the second end portion of the elongated body member is caused to cross over a ball striking zone when the individual's hips, lower body and upper body are properly rotated during the swing or ball striking motion. The apparatus may further include a back rest assembly, a rib assembly and a propiteal fossa engaging assembly.

Abstract: A method and apparatus for thermal processing a photosensitive element includes heating a composition layer on a flexible substrate to a melt temperature of an unirradiated area of the composition layer and maintaining the flexible substrate at a temperature below the melt temperature while pressing a heated absorbent layer against the heated composition layer, and repeating these steps for multiple cycles. A further embodiment of the method includes a step of cooling the flexible substrate and layer laminate on each cycle to maintain the flexible substrate at the desired temperature below that of the heated composition layer.

Abstract: The present invention is directed to: a non-interlacing expirating yarn bulker comprising a body having an enclosed yarn passage extending therethrough. The yarn passage includes an inlet region, a throat region and an expanding region. A single pressurized fluid channel extends through the body and intersects with the yarn passage in the throat region. Cross sectional areas at certain defined locations in the yarn passage exhibit predetermined relationships. In addition, the inlet region and the pressurized fluid channel both are symmetrical about a common reference plane of symmetry;a replaceable wear member insertable into a body of a jet having a yarn passage with an inlet region and a throat region. The wear member has an upstream face, a downstream face, and a channel extending therebetween. The intersection of the channel and the downstream face of the member defines a wear edge.

Abstract: A sensor for use with a yarn processing apparatus that includes at least one roll over at least a portion of the surface of which at least one yarn is conveyed is operative to generate an accumulation signal representative of a wrap accumulation of yarn circumferentially around the surface of the roll.

Abstract: A baffle structure that includes a generally cylindrical portion and at least one generally linear portion is associated with each roll in a yarn processing. The generally cylindrical portion is spaced a predetermined clearance distance from the surface of the roll with which it is associated to define a generally curved channel about the roll. The generally linear portion of each baffle structure extends toward the other roll, with the generally linear portions overlapping each other to define a substantially linear channel between adjacent upstream and the downstream rolls. The generally linear portion extending from the cylindrical portion of the upstream roll toward the downstream roll has an edge thereon. The edge is disposed within a predetermined close distance of the surface of the upstream roll such that the edge lies within the boundary layer of air able to be generated about the upstream roll.

Abstract: An integral structure is provided for chemical processing and manufacture, in which a plurality of laminae are joined together and having inlet and outlet ports connected by a three dimensionally tortuous channel. Chemicals are introduced through the inlet ports and processed along the channel, with desirable product withdrawn through the outlet ports. The laminae are of materials selected to be compatible with the chemical process, from the group consisting of elements of groups III, IV or V of the Periodic Table, ceramics, glasses, polymers, composites and metals. Processes of manufacture of the apparatus and processes utilizing the apparatus are also disclosed herein.

Abstract: A process for the encapsulating of substances immiscible with water by dispersing the substance to be encapsulated in a distribution medium in the presence of a hydrate or bisulphite adduct of a polyacrolein or acrolein copolymer and reacting said hydrate or bisulphite adduct with a water-soluble, polyfunctional, monomeric or polymeric hydrophilic compound and, optionally, additionally with a curing agent or an aminoplast precondensate to form an insoluble capsule.

Abstract: A running yarn is spliced into a running tow by entangling filaments of the tow with and about filaments of the yarn with an air-jet device, the leading portion of the yarn is severed to leave a small protruding tail, and the tail is entangled within the tow with a second air-jet device. The air-jet devices comprise two halves which are separated and positioned on each side of the tow until a splice is to be formed; they are then closed to form cylindrical treatment chambers of diameters which impart a rounded shape to the tow, so that filaments are entangled about the yarn by the air jets. The air-jet devices are preferably designed to provide a forwarding action on the filaments.

Abstract: Leather is coated on at least one face with a curable composition comprisingI. a polymercaptan containing at least two mercaptan groups per average molecule,Ii. a polyene having, per average molecule, at least two ethylenic double bonds, each .beta. to an atom of nitrogen, sulfur, or oxygen, the sum of the mercaptan groups in the polymercaptan and of such ethylenic double bonds in the polyene being more than 4, and the composition is then cured on the leather with or without the application of heat, optionally in the presence of a Bronsted acid, a Bronsted base, or a source of free radicals, as a curing accelerator.In this manner the leather is provided with a wearing or decorative surface having high gloss and smoothness, enhanced ease of cleaning, and decreased permeability to liquids.

Abstract: A process for finishing keratinous material, especially rendering it shrink-resistant or imparting to it durably pressed effects, comprises1. treating the material with a polythiol ester of the formula ##EQU1## WHERE R.sup.1 represents an aliphatic or araliphatic hydrocarbon radical of at least 2 carbon atoms, which may contain not more than one ether oxygen atom,R.sup.2 represents a hydrocarbon radical,p is an integer of from 2 to 6,q is zero or a positive integer of at most 3, such that (p + q) is at most 6, andr and s each represent zero or 1 but are not the same, and2. curing the polythiol ester on the material by means of a polyene containing, per average molecule, at least two ethylenic double bonds each .beta. to an oxygen, nitrogen, or sulfur atom, the sum of such ethylenic double bonds in the polyene and of the mercaptan groups in the polythiol ester being more than 4 and the combined weight of the polyene and the polythiol ester being from 0.5 to 15% by weight of the keratinous material treated.

Abstract: An improved suction nozzle is comprised of a narrow constant height slot passageway open at one end and communicating at the other end with an expansion chamber which, in turn, is connected to a cylindrical manifold. An orifice in the end of the manifold assists in the development of parallel fluid flow along the manifold axis.
