Patent EP-0493667-A1 (EP)
Inventor: SCHMIDT WALTER
IPC: B29C48/03
Filed: 1991-11-18
Abstract: The invention relates to an extruder head, comprising a feed part (3), which is fastened to the flange plate of the extruder barrel, surrounds a section of the channel carrying the extrudate to the extrusion dies and has a projection (5) in the surface of which there is formed a distributing surface for the extrudate has half of a further section of the channel, comprising an end part, which surrounds the die(s), is fastened removably to the projection (5) of the feed part (3) and comprising a central part, which is enclosed by the two other parts and forms on the side facing the projection (5) of the feed part (3) the other half of the section of the channel for extrudate distribution, the feed part bearing a further projection, serving as abutment, at the other end of the parting surface between feed part (3) and central part (10), and the central part (10) having two further parting surfaces, which run at obtuse angles to the first-mentioned parting surface and bear against the projections. It is the object of the invention to join the three parts (3,9,10) together with the necessary firmness by as few screw connections as possible and also to gain sufficient surface area for the attachment of additional parts. The invention consists in that, at both the lateral ends of the central part (10), screw bolts (26) engage through holes made in the latter approximately perpendicularly to the plane of the distributing surfaces into the projection on the feed part (3), in that, perpendicularly to the parting surface (13) between feed part (3) and central part (10), screws (12) in the central section connect these parts to each other, in that the end part (9) is fastened by a series of screws (11) to the central part (10) and by a further series of screws (8) to the projection (5), and in that a removable bar (16), on which the central part bears, is fastened to the abutment. <IMAGE>

Abstract: The pivoting device has at least one pivoting arm (1) which is arranged on at least one support (2). There engages on the pivoting arm at least one brake (7, 9) which is ineffective when pivoted up and secures the pivoting arm (1) against pivoting back. When the pivoting arm (1) is pivoted down, the brake (7, 9) comes into operation so that the pivoting arm (1) cannot fall down unintentionally. As the brake (7, 9) is made inoperational when the pivoting arm (1) is pivoted up, only the dead weight of the pivoting arm (1) has to be pushed up, which even disabled persons can carry out easily. <IMAGE>

Abstract: A venting cap (1) has a female luer taper (2) which fits on the male tapered nose (53) of an arterial blood sampling syringe (50). The cap has a hydrophilic filter (6, 75) of porous polyethylene impregnated with cellulose. Gas is purged from the syringe by holding the capped end of the syringe above its plunger (51) and advancing the plunger until gas and arterial blood is expelled from the nose (53). When blood contacts the filter (6, 75), the filter expands and seals preventing escape of blood. The cap may include a flow restrictor (10) which concentrates blood flow to only a portion of the filter and thereby prevents premature sealing.

Abstract: The present invention is a method for separating a gaseous mixture to produce an enriched gas having a predetermined purity which comprises the steps of a) passing the gaseous mixture into a first adsorption bed at an adsorption pressure in the range from about 15 psig to about 500 psig, b) withdrawing enriched gas from the first adsorption bed and passing the enriched gas into a product reservoir, c) when the purity of the enriched gas from the first adsorption bed drops below the predetermined purity thereby becoming lean gas, passing then lean gas from the first adsorption bed into a second adsorption bed to substantailly equalise the pressure of the beds, d) stopping the flow of lean gas from the first adsorption bed and evacuating the first adsorption bed while purging the first adsorption bed by passing enriched gas from the product reservoir into the first adsorption bed, e) further pressuring the second adsorption bed by passing enriched gas from the product reservoir into the second adsorption bed to back fill the second adsorption bed, f) further pressurising the second adsorption bed by passing the gaseous mixture into the second adsorption bed at abn adsorption pressure in the range from about 15 psig to about 500 psig, and g) repeating the above steps in a continuous cycle treating the second adsorption bed like the first adsorption bed and the first adsorption bed like the second adsorption bed.

Abstract: An air turn comprises air bars (12) supported on a body (10) at spaced points (16, 17) so that the air bars lie in an arcuate path to define a web travel path about the turn. The air bars (12) have Coanda nozzles to create a web-supporting air cushion. The supports at the jacking points (16, 17) are individually adjustable to enable the air bars (12) to be bent slightly to a convex arcuate shape as seen tangentially to the turn. Dampers (54) in inlets (48, 50, 52) control the air supply individually to zones (33, 35, 37) along the air bars. Baffles (58) regulate the air flow to exhaust zones (56) between the air bars to create higher and lower pressure zones supporting the web. 
     These measures each reduce the risk of the web creasing or folding.

Abstract: A structure of a ferroelectric capacitor (C) is provided on a source region (24) between a gate electrode (23) and a local oxide film (26). The capacitor (C) has a ferroelectric film (29) sandwiched between an upper electrode (32) and a lower electrode (28), and a film (31) for preventing oxygen from diffusing between the lower electrode (28) and a first interlayer insulating film (30). The film (31) is made of SiN or SiON. Even if for the purpose of transforming the crystallinity of the ferroelectric film (29) it is subjected to an oxygen annealing treatment, oxygen is blocked by the film (31). Therefore, the variation of the threshold voltage and the increase of the leakage current of a transistor scarcely occur. Thereby, the degree of freedom of setting the condition of forming ferroelectric film increases, and a ferroelectric memory of high performance and of large scale integration can be formed.
