Abstract: An exercise garment includes an outer layer of clothing which is in the form of a warm up suit or sweatsuit loosely fitting on the user. An inner layer of clothing made of elastic resistance material is secured to the inside of the outer layer of clothing. The inner layer of clothing is anchored at spaced locations so that the user is required to stretch the material of the inner layer during various body movements while the outer layer remains loose fitting.

Abstract: Dye mixtures of fiber-reactive azo dyes and their use for dyeing hydroxy- and/or carboxamido-containing fiber materialRed-dyeing fiber-reactive phenylazoaminonaphthol dyes, yellow-dyeing fiber-reactive phenylazoaminobenzene dyes, blue-dyeing fiber-reactive copper formazan dyes and navy-dyeing fiber-reactive disazo dyes of the formulae (1) to (5) as claimed and defined in claim 1 are described which are suitable for dyeing hydroxy- and/or carboxamido-containing fiber material, such as cellulose fiber materials, wool and synthetic polyamide fibers individually or together or some of them together or as a mixture in trichromatic dyeing methods. During the dyeing process a definite hue within the color triangle can be obtained and kept constant by adding the individual dye solutions of the individual dyes and/or mixtures of some of the dyes in a controlled manner by means of the ATR measurement technique.

Abstract: Daylight loading packaging for photographic paper in the form of rolls comprising lateral, annular flanges and a casing lengthening piece welded to the flanges, which casing lengthening piece is connected at one end to the start of the paper roll and is free at the other end, the flanges presenting a concentric annular hole the edge of which is welded to the edge of the roll tube and which on one side of a paper base has at least one blackened layer forming a light barrier, at least one aluminium layer forming a vapour barrier, at least one layer which increases resistance to puncture, and furthest away from the paper base a layer which permits welding to the casing lengthening piece and the roll tube, and which has on the other side of the paper base a layer of a synthetic polymer applied by extrusion which imparts a tension to the material which prevents an inward collapse of the flange (seen from the roll).

Abstract: The invention relates to Pd/K/Au, Pd/K/Ba or Pd/K/Cd supported catalysts built up in the form of an outer layer, the production thereof and the use thereof for preparing vinylacetate from ethylene, acetic acid and oxygen in the gas phase. The specified catalysts are produced by impregnating the support particles with a solution of salts of the corresponding elements and then drying them, with the dynamic viscosity of the solution being at least 0.003 Pa.s and the solution volume in impregnation being more than 80% of the pore volume of the support particles and the duration of the impregnation and also the time until commencement of the drying being selected so as to be sufficiently short for, after completion of the drying, the specified metal salts to be present in an outer layer of from 5% to 80% of the pore volume of the support particles.
Abstract: An easy-opening blister card package is disclosed having a rigid container sheet with cavities formed in it and a closure sheet to seal the cavities. Between the cavities are finger tabs that are accessible by detaching individual sections of the blister card package. Once a section is detached, a finger tab is exposed which is pulled to form a larger pull tab. The pull tab is sufficiently large to allow the user to comfortably grasp it to peel apart the sealed layers. An alternate embodiment of the invention discloses a child-resistant blister card package wherein an additional seal must be broken to form the pull tab.

Abstract: An improved metal-semiconductor-metal (MSM) photodiode, specifically a new high responsivity AND high bandwidth photodetector, resulting in a high gain-bandwidth product is disclosed. The disclosed device is an MSM photodiode in which the anode and cathode are made of different materials of differing opacity and possibly including different electrode dimensions as well. Using an opaque anode and a transparent cathode reduces surface reflections off the opaque electrodes allowing more light to be absorbed within the active semiconductor region. However, it concurrently keeps the transit distance for the slower moving holes to a minimum. Thus, the long tail in the impulse response due to hole collection is minimized, resulting in increased bandwidth.
Abstract: Process for the preparation of acyloxyalkanesulfonates having improved properties The acyloxyalkanesulfonates are obtained in accordance with the invention by direct esterification in which at least one fatty acid is esterified with at least one ammonium hydroxyalkanesulfonate of the formula HO-A-SO.sub.3.sup.- + NR.sup.1 R.sup.2 R.sup.3 R.sup.4 in which A is a C.sub.2 -C.sub.4 -alkylene and R.sup.1.sub.1 R.sup.2.sub.1 R.sup.3 and R.sup.4 are hydrogen or a C.sub.1 -C.sub.4 -alkylene group in the presence of an esterification catalyst at a temperature of not more than 200.degree. C., with removal of the water present. This process gives a product of high acyloxyalkane-ammonium sulfonate content without the need for a consistency regulator to be added.

Abstract: An electrically controlled faucet is disclosed which is operable by pushing a button or placing hands within the operating range of a sensor. The faucet is mounted to a sink deck or like surface using specially configured gasket means which insure against slippage of the faucet on the deck. The gasketing means provide special channels through which electrical operating wires can be securely passed from the faucet to operating means below the sink deck. These operating means include a solenoid valve that controls fluid flow through the faucet and a temperature control valve fluidly linked to the solenoid valve. Solenoid disabling pressure buildup in the line linking the temperature control valve and solenoid is bled through special bleed means in the temperature control valve inlets.
Abstract: Polyaspartate, useful for inhibition of incrustations due to materials causing hardness in water and of value in detergent formulations, can be prepared by reacting maleic acid or fumaric acid in a molar ratio of 1:1-2.1 at temperatures greater than 190.degree. C., followed by conversion of the polymer formed in this reaction to a salt of polyaspartic acid by basic hydrolysis.
