Disclosed herewith is an improved reel assembly for surveyors and other construction trades wherein the resilient member that retrieves the plumb line or string is entirely enclosed in the spool assembly that is contained within the housing of the reel assembly. The spool assembly is formed so that it is difficult to obtain access to the resilient member thereby precluding inadvertent release of t...

In a combustion apparatus, gas for combustion is fed in a combustion chamber receiving a heating medium such as sand to continuously blow the heating medium upwardly to thereby circulate the heating medium in the combustion chamber.

A method of making a shielding gasket integral with a surface comprising the steps of (a) preparing a gasket material consisting of a mixture of an elastomer, a conductive filler, a catalyst and a bonding agent; (b) filling a mold with the gasket material; (c) covering the mold with a surface chosen to be bonded to the gasket; and (d) curing the gasket material in contact with the surface to utili...

A process for producing olefins and gasoline from residual oil by thermally cracking a side cut fraction from a fractionation tower, quenching the cracked product with residual oil, producing coke from a portion of the quenched product and using a portion of the coke to provide reaction heat for the thermal cracking.

A heat-recoverable article for bonding to an object, particularly for sealing a joint between pre-insulated pipes, consists of a layer of heat-recoverable polymeric material (23), a layer of a bonding material (30,32) which preferably is heat-activatable, and a laminar metal heating element (24,26) which has a plurality of apertures through its thickness to permit the element to be deformed in the...

A necklace device has two skin electrodes mechanically tethered to it at relatively widely separated locations to detect the wearer's heart beat or another body signal. The electrodes are electrically connected, by the necklace itself or by conductors which it conceals, to circuitry in a pendant or other necklace ornament. The pendant circuit processes the body signal and may store it, display inf...

A process for converting alpha -hydroxycarboxylic acids to hydroxy free aliphatic carboxylic acids and aldehydes in the presence of a catalyst of the formula: MaM'bOx wherein M is at least one of an element selected from Group IB, VIB, IVA; and M' is at least one of an element selected from Groups IA, IIA, IVA, VA, VIA, VIIIB, VB.

Body member conformable disposable articles and processes for their preparation are described. A preferred embodiment is a disposable absorbent article comprising a flexible, elastic, moisture impermeable backing film, an absorbent layer superposed thereon and a moisture permeable topsheet joined to the backing film along the edges of the topsheet. A portion of at least one longitudinal edge of th...

A sanitary towel for absorbing body fluids composed of an absorptive hydrophilic fiber filling having a cover, the cover being composed of a liquid-impermeable composite material and having a defined liquid-permeable zone. The core of the filling material contains an insert having high absorptive polymers therein and being covered with a liquid-permeable woven carrier material, fleece or tissue. S...

A disposable diaper has a moisture impermeable backing sheet, a fibrous absorbent batt and a flexible hydrophobic facing sheet overlying the batt, the components being secured together to form a sandwich structure; the facing sheet has an aperture in the central crotch region of the diaper with zones of elastication in the facing sheet tending to apply tensioning forces to the facing sheet for urg...

A method for separating a basic amino acid from its fermentation broth, or the liquid resulting from the intermediate treatment of the fermentation broth, containing high-molecular weight contaminants which entails permeating the broth, or liquids resulting from the intermediate treatment of the broth, through a semi-permeable membrane, until the basic amino acid is separated from the high-molecul...

TOUCH TYPE COMPUTER KEYBOARDS Disclosed is a computer system comprising a keyboard provided with an array of keys, the keys being manually actuable by single finger strokes to enter information to the system dependent upon the keys actuated, wherein the computer system is switchable by a single finger stroke applied to the keyboard into a program mode of operation in which instructions may be ente...

An anatomically form-fitting, generally self-adjusting disposable absorbent garment (10) comprising an outer cover (20), absorbent means (22), disposed within the outer cover (20), for absorbing and containing body fluids and other exudates. Full-length, fixed position fasteners (70, 72, 74, 76) are attached to the outer cover (20) for securing the disposable garment (10) around a wearer and provi...

Apparatus for damping torsional vibrations in the power trains of motor vehicles has a first flywheel connected to the crankshaft of the engine and a second flywheel which is rotatable relative to the first flywheel and can be coupled to the input shaft of the change-speed transmission by a friction clutch. Angular movements of the flywheels relative to each other are opposed by a hydraulic damper...

An apertured, autogenously bonded fibrous web substrate. A nonwoven web contains apertures with a consolidated or densified area surrounding each of the apertures to attract fluid and allow easy passage thereof through the nonwoven web.
