Abstract: A hindgas implement for protective gas coverage of the root of a welded seam that may be fixed to work pieces to be welded by means of vacuum chambers (11, 13) that are emptied of air via pipe branches (25). After that protective gas is fed to the root of the welded seam via a diffusor (19) and is withdrawn via outlets (21, 23). By means of this, hindgas coverage can also be achieved in welding together of major, extensive work pieces made up of plate as there is no dependence on free edges on which to clamp the hindgas device.

Abstract: 1521125 Cellulose nitrites, sulphates and nitrates R G SCHWEIGER 8 July 1975 [10 July 1974] 28676/75 Heading C3A Nitrite esters of cellulose which may be converted to sulphates or nitrates are prepared by reacting water-containing, cellulose having not more than 12% water content with dinitrogen tetroxide or nitrosyl chloride at less than 50‹ C. with stirring in the presence of at least three parts by weight of a swelling or solubilizing solvent for the nitrite ester per part by weight of cellulose in the presence of proton acceptor. The cellulose preferably contains 4-12% water by treatment with a highly polar aprotic solvent. The solvent used is N,N-dimethylformamide and the highly polar aprotic solvent may be N,N-dimethylformamide, N,N-dimethylacetamide or pyridine. The sulphate ester may be prepared by reacting the nitrile ester with SO3 or a complex thereof and neutralizing with a base to give the alkali salt form.

Abstract: The use of certain prepolymers of 4,4'-methyienebis-(phenyl isocyanate), in place of the latter diisocyanate itself in the preparation of polyurethane-polyureas using aromatic diamine extenders, has a number of advantages par- ticuiariy when the compositions are prepared by reaction injection molding techniques using two streams of reactants. The principal advantages are (i) a useful increase in gel time and (ii) a ratio of amounts of the two reactant streams which more nearly approaches 1:1.This latter factor not only improves the efficiency of mixing of the components in the mixing head but, together with the longer gel time, significantly increases the output of mixed reactants per unit of time. The prepolymers of 4,4'- methyienebis(phenyi isocyanate) employed to achieve the above results are those derived from polyoxy-ethylene polyoxypropylene polyether diols and triols (MW = 1000-10.000), polytetramethylene glycols (MW = 600-5.000) and polyester diols and triols (MW = 500-8.000).

Granted: 2000-10-24
Abstract: A wave-forming generator for generating inclined surfaces on a contained body of water. The water is propelled against the surface-shaping generator with sufficient force to impart the desired shape to the water surface, and the generated surfaces can include waves, such as tunnel waves, appropriate for surfing and other water skimming manuevers on the surface of a body of water. Surfaces generated can require a wide range of skills to negotiate, from beginning to advanced levels. The surfaces generated are substantially stationary with respect to the water containment means, the water itself moving with respect thereto.

Abstract: A low profile alternating current electrical plug is disclosed in which the electrical pins are terminated in lands at right angles to the axis of the pins. These lands are used for crimping wires to the pins as well as for mechanically stabilizing the pins in the molded plug body. Forming these lands at right angles to the pin axis permits a very thin plug body. The electrical cord exits the plug head at an acute angle to the line of the power pins as well as at an acute angle to the axis of a mating electrical outlet. The wires exit the plug head, however, at a right angle to the pin axes and parallel to the wall thereby maintaining the low profile. At the wire exit, a cone-shaped sleeve acts as a shock absorber for forces exerted on the cord, thereby absorbing most of these forces before they reach the pin area. A removal ring is made integral with the low profile plug, lying parallel to the plug when not in use, but pivoting to a perpendicular position when grasped by a finger. Due to the low profile of the plug and the wall-hugging position of the cord, decorative covers can be installed over both the wire and the plugs, making the entire electrical installation aesthetically appealing.

Title: Magnesium treatment process and apparatus for carrying out this process
Inventor: HENYCH IVO
IPC: C21C1/10
Filed: 1990-11-28
Granted: 2000-01-18
Abstract: A magnesium treatment process is proposed for the production of a treated iron melt 1 containing less than 100 g/t non-metallic inclusions. The treatment reaction is so arranged that the magnesium is introduced into the melt from a chamber 4 at a depth of at least 200 mm below the surface 10. Thus the quantity of vaporised magnesium produces a mixing energy of at least 1,000 W/m3, which ensures the necessary elimination of non-metallic inclusions. The surface of the molten mass is covered by a non-oxidising, preferably a reducing atmosphere.

Title: Supported-lip low interference metal stab seal
Inventor: DOWNES STEPHEN
IPC: E21B33/04
Filed: 1992-01-09
Granted: 2003-07-29
Abstract: An improved metal-to-metal seal of a generally U shaped configuration which utilizes an enlarged seal portion on the interior and exterior of the inner and outer seal legs to effect an initial seal. The initial interference of the seal legs is maintained by disposing a solid support ring in the annulus between the seal legs with holes in the support ring to prevent pressure lock and to balance pressure distribution within the seal. The invention is shown in a unidirectional form with a single pair of seal legs extending axially from an annular base and in a bidirectional form with a pair of seal legs extending axially in both directions from an annular base. An alternative form of the invention discloses a support member of U shaped configuration which allows greater flexibility in the seal legs while maintaining initial sealing contact. This support member also has holes to prevent pressure lock and to balance pressure distribution within the seal. The seal legs are manufactured of a relatively softer material while the support member is manufactured of a higher strength material to ensure an initial interference type seal.
