Abstract: A device in a cutting torch which comprises a torch body with a valve housing and a nozzle and with a cutting oxygen duct, a heating oxygen duct and a combustion gas duct disposed in the torch, there being disposed in the torch a connection line which contains a throttling member between the heating oxygen duct and the cutting oxygen duct and wherein disposed in the cutting oxygen duct before the connection line is a valve member which permits a flow of heating oxygen to pass through the cutting oxygen duct only in the direction towards the orifice of the nozzle.The connection line between the heating oxygen duct and the cutting oxygen duct comprises at least one cooling oxygen duct (7) disposed in the nozzle which is elaborated with three sealing surfaces towards the torch body. The cooling oxygen duct (7) has a diameter which is so adapted in relation to the orifice diameter in the cutting oxygen duct of the nozzle and to the size of the heating flame that during heating of the workpiece a cooling oxygen pressure is rapidly built up in the cooling oxygen duct which prevents hot combustion gases from penetrating into the cutting oxygen ducts and that in the case of short nozzle distances to the workpiece the flow of cooling oxygen is prevented from becoming so great that the surface of the workpiece which is situated below the orifice of the cutting oxygen duct is cooled so rapidly that hole-piercing is rendered more difficult.

Abstract: A high pressure relief valve including a housing, an applied spring assembly, a valve seat with a seat opening, a valve poppet, a valve stem, a C-bracket, and an adjusting drive. The valve is intended for pressure relief of liquid hot-separator product which may contain solid components in the form of ash, catalyst, and unreacted coal components. The hot-separator product may be, in particular, a product of the hydrogenative liquefaction of coal. To obtain improved service life of the parts subject to wear, as well as to obtain good control characteristics and a tight valve closure, the valve has the following characteristics: (a) the throttle gap between the valve seat (10) and the valve poppet (11) is in the form of a surface gap between two broad-surfaced (or shallow-surfaced) bodies; (b) an excursion of the valve poppet (11) is produced by actuation of the adjusting drive (4); and (c) the excursion of the adjusting drive (4) is converted into rotary motion of a stem nut (3), which latter motion is converted to a lesser (i.e., geared down) prescribed linear motion of the valve stem (2) via an interior screw or worm part.

Abstract: Contact lenses can be made by machining an inner concave surface into a plastics material blank, then mounting the blank in a lathe and machining the outer convex surface thereon. Repeated measurement with a micrometer is needed during the latter machining to ensure that the lens vertex is correctly formed. To avoid this, the sensor described herein comprises a laser source (12) from which radiation passes over a knife edge member (13) and the blank (10) to a detector (15), the items being arranged so that, when the lens has been correctly machined, a surface diffraction effect occurs leading to a detectable signal from the detector (15). The disclosed sensor apparatus could be used during manufacture of items other than contact lenses.

Abstract: This invention relates to novel therapeutic uses of beta-adrenergic agonists in humans and animals. The uses include increasing muscle growth and reducing fat uptake from dietary input, retarding or reversing atrophy of denervated muscle, alleviating or reversing the effects of various diseases (including cancer), modification of foetal and neonatal growth, and possible genetic modifications of the developing foetus. The preferred beta-adrenergic agonist is clenbuterol. Surprisingly, the beta-adrenergic agonist can be mixed with a beta-adrenergic antagonist to obviate or mitigate unwanted side-effects without excessively inhibiting the wanted novel effects.

Abstract: The aim of the invention is to provide a method for determining significant losses in bone density which is less cost-intensive, does not expose the patient to radiation and whose response time is shortened in terms of the interaction between osteoclasis and osteosteosis. According to the invention, this is achieved by using measuring values of real or mathematically simulated processes of bone density losses contained in electronic storage media, reflecting the temporal dependency of laboratory parameters with respect to practically or theoretically known clinical symptoms, as reference values during the process. Measuring values of bone markers are determined, using widespread laboratory techniques, from serum or urine samples during steps in which the samples are prepared such as the addition of antibodies, incubation stops, separation methods and insertion in analysis techniques. Said values are associated with losses in bone density and are written into an electronic data memory with the aid of an input marker. According to the invention, said values are used to determined significant losses in bone density.
