Abstract: An abutment swivel doorstop has a mounting plate mountable onto a door frame, a stop member pivotally and slidably mounted on the mounting plate, a biasing means for urging the stop member in the disengaged position, a keeper pivotally mounted on the mounting plate, and a latch mountable on a door which is hingedly mounted within the door frame. The stop member is rotatable between a door opening position and a door blocking position and slidable between a disengaged and engaged position. The keeper is rotatable relative to the stop member between a locked and an unlocked condition. The keeper has a cam for urging the stop member against the biasing means and into the engaged condition as the keeper rotates between the locked and unlocked conditions. As the keeper rotates between the locked and unlocked conditions, the stop member engages and disengages the mounting plate and the latch for locking and unlocking the door to the door frame.

Abstract: A  hydroforming  process  and  apparatus  for  manufacturing components  of  a  vehicle  exhaust  or  intake  manifold.    The hydroforming process is utilized to form a tubular member to the desired configuration for use in a manifold.  The tubular member is loaded into a hydroform press and filled with a suitable liquid. The liquid within the tube is pressurized in order to maintain a predetermined internal fluid pressure which prevents collapse and crimping of the tube during forming.  The hydroform press includes two sets of dies to form a compound bend in the pressurized tube. Upper and lower dies close on the tube first to bend the tube in a vertical plane.  Horizontal dies are wedged inwardly spreading the first die set and bending the tube in a horizontal plane.  As a result, a compound configuration may be placed on the tube making it suitable for use in a vehicle manifold.

Abstract: The filter device (10), provided for the filtration of fluids, comprises two interconnected material structures (14, 16) forming a filter unit (12). The two material structures (14, 16) are mechanically stable, at least one of the two material structures (14, 16) being elastically deformable. The two material structures (14, 16) an connected to each other at opposite connecting sites, with one (16) of the material structures forming an arch between the connecting sites. This arch has been generated by elastic deformation of the respective material structure (16) so that this material structure (16) is mechanically biased. A stretching movement of this material structure (16) is prevented by the connection of this material structure (16) to the other material structure (14) which in turn is of substantially plane configuration and is tensioned. Each thus constructed filter unit (12) offers high stability against the forces generated by the fluid flow so that a filter element (10) comprising such filter units can be inserted without additional constructions or elements which maintain the arched structure of the curved one material structure (16).

Abstract: This invention relates to a process for reduction of virus inactivating chemicals and/or detergents in an aqueous composition containing a water-soluble plasma protein. By selecting a suitable combination of temperature and concentration above 0.5 M of a salt with a high salting out effect according to the Hofmeister series, vesicles containing the virus inactivating chemical and/or detergent are formed. These vesicles are removed from the aqueous phase, e.g. by phase separation or filtration, and the protein thereafter isolated from the aqueous phase. The water-soluble plasma protein can be e.g. antithrombin III, transferrin or albumin. When the aqueous phase comprises e.g. a salt of citrate or sulphate in a concentration above 1 M at room temperature, the reduction of virus inactivating chemical or detergent can be as high as 2000 times or more, giving a final concentration below 5 ppm.

Abstract: An aluminum melting method wherein an atmosphere above the aluminum charge is comprised of two strata, a lower strata covering the aluminum charge comprised of a non-oxidizing gas and an upper strata comprised of combustion gases from one or more burners.  Heat from the burner or burners radiatively heats and melts the aluminum while the lower strata protects the aluminum from oxidative effects which would result if the aluminum surface were contacted with the combustion gases, thus serving to reduce dross formation.

Abstract: A method of producing micron sized sulphur granules involving the following described steps.   Firstly, heating sulphur until the sulphur becomes molten.  Secondly, heating water and inducing movement of the heated water at velocity. Thirdly, injecting an unbroken stream of the molten sulphur under pressures in excess of 500 p.s.i. into the heated water moving at velocity.   An explosive dispersion of the molten sulphur into fine sulphur granules occurs, enhanced by shear forces exerted by the movement of the heated water at velocity. The described method is capable of producing spherical sulphur granules of less than 45 microns.  In the preferred ranges, spherical  sulphur granules of less than 10 microns can be obtained.

Abstract: A hockey stick is provided with an offset or bend angular to the plane of the face of the blade and positioned to begin substantially at the location where the transition from the heel of the stick to the shaft becomes approximately equal to the cross section of the shaft in its parallel plane. In a preferred form a second bend then makes a rapid transition to the full offset configuration within the dimension of the shaft such that the blade portion trails the plane of the center line axis of the shaft and due to centrifugal force the trailing blade tends to rotate closed thereby cupping the puck by the blade results in reduced deflection and easier pass reception. According to the preferred embodiments, the offset is positioned where it can be located closest to the blade and in the parallel offset form the completion of the offset to its full off-set dimension takes place dimensionally as is possible within a unitary stick construction of a blade with shaft receiving handle portion. The offset of the invention can be directed positively or negatively angled for different affects and performances.
