Patent EP-0342420-A2 (EP)
Inventor: RENZ WALTER DIPL-ING FH
IPC: E05B65/00
Filed: 1989-04-29
Abstract: When the frames of the wings (3, 4, 5) of a sliding folding element (2), for example a sliding folding door, are produced from plastic sections or from thin aluminium sections, these are sensitive to distortion even when they are equipped with reinforcement, because the latter cannot extend right into the frame corner. To ensure that the load on the second wing (4) and further wings during the opening of the first wing is reduced to a minimum, the second wing (4) can open only when the first wing (3) is opened at approximately 180 DEG and retained on the second wing (4) by means of a first locking device (17). Released particularly via the first wing (1) is a second locking device (18), by means of which the second wing (4) is fixed relative to a stationary frame (1). By means of a third locking device (19), the folded-together position of the first and second wings can be secured additionally in the initial opening movement of the second wing (4). <IMAGE>

Abstract: A fiber spool apparatus for a braiding machine or the like, comprising a support (12), a fiber supply spool (20) rotatably mounted on the support (12), a housing (18) fixedly mounted on the support (12) and having a plurality of recessed portions on the inner surface thereof, and a coil spring mounted within the housing (18). The coil spring has an inner end operatively associated with the spool (20) and an outer end in engagement with the inner surface of the housing (18). Wenn fiber (F) is fed from the spool (20) to the braiding machine, the spool (20) is rotated in a first direction to wind and tension the spring by engagement of the outer end thereof in one of the recessed portions in the housing (18) rotation of the spool (20) in the first direction until the spring reaches a predetermined tension. Continued rotation of the spool (20) in the first direction causes the outer spring end to slip from one recessed portion to another after the spring has reached the predetermined tension. In the event of slack in the fiber (F) being fed to the braiding machine, the tensioned coil spring , by engagement of its outer end in one of the recessed portions of the housing (18), causes the spool (20) to rotate in the opposite direction to maintain tension in the fiber (F).

Abstract: An image display apparatus comprising an insulating substrate (1) having electron sources (13) controlled by X-Y matrix electrodes (10, 11) and a face plate (4) coated with a phosphor material in opposed relationship with the substrate is disclosed. An electron source at each intersection of the X-Y matrix control electrondes is made up of a plurality of cold cathodes (2) connected to an X-control electrode (10) and a plurality of gate electrodes (3) connected to a Y-control electrode (11) opposed to the cold cathodes in the same plane, and the electron source is formed on the substrate surface on other than the X- and Y-control electrodes. A voltage applied between the cold cathodes and gate electrodes arranged in opposed relations on the same surface causes a high electric field of about 10⁷ V/cm at the forward end of the cold cathodes leading to an electron emission. A part of electrons thus emitted enters the anodes directly. Another part of electrons flow into the opposed gate electrodes to generate secondary electrons in the surface of the gate electrodes. The secondary electrons thus generated are accelerated by the positive voltage (anode voltage) applied to the phosphor surface of the opposed face plate and bombarded on the phosphor material, which is thus illuminated.

Abstract: Disclosed is a pneumatically-driven bellows pump (2) apparatus for oscillating liquid into a localized area of the human body, preferably methyl-tertiary butyl ether or another solvent, into the gallbladder (4). The pump (2) includes a fluid reservoir in the form of an inverted syringe (16) attached via a stopcock (14) to the bellows. The bellows (7) is attached via a second stopcock (11) to a catheter (3) also attached to a priming syringe (10). An inlet pinch valve (13) is disposed between the bellows (7) and the fluid reservoir and an outlet pinch valve (12) between the bellows and the fluid receiver. 
     To use the pump, a pigtail catheter (3) with outlets in the pigtail is inserted into the desired area of the body, preferably a receptacle such as the gallbladder (4), to introduce liquid for gallstone (5) dissolution. Liquid is infused into the receptacle by decompression of the bellows (7) with the inlet (13) but not the outlet (12) valve open and then by compression of the bellows (7) with the outlet (12) but not the inlet (13) valve open. Repeated infusion and aspiration is accomplished by decompression and compression of the bellows (7) with the inlet valve (13) closed and the outlet (12) valve open, or by compression and decompression of the bellows (7) while the inlet valve (13) is open and the outlet valve (12) is closed alternated with compression and decompression while the inlet valve (13) is closed and the outlet valve (12) is open. Complete aspiration is accomplished by the use of a vacuum pump attached to the fluid reservoir. Also disclosed are syringe units and a transfer cap for use with the pump (2), together with a method for dissolving gallstones (5).

Abstract: Compositions which cure to gels by exposure to ultraviolet radiation are made by blending a photoinitiator with an acrylamide functional polyorganosiloxane having 1 to 2 siloxane units which contain acylamide groups which can be acrylamide or a combination of acrylamide and acetylamide. The hardness of the gel can be adjusted by varying the ratio of acrylamide and acetylamide in the polyorganosiloxane where the harder gels have the highest percentage of acrylamide groups. The autoclave stability of the gels can be increased by including in the compositions a tertiary amine which neutralizes the by-produced acids from decomposition of the photoinitiators. These gels have low temperature flexibility, can be made with a durometer to fit the particular application and can be made to have autoclave stability. The gels are useful as encapsulants for electronic devices.

Abstract: An improved method is disclosed for generating a compressed representation of a source data string each symbol of which is taken from a finite set of m + 1 symbols, a₀ to a m  . 'The method is based on an arithmetic coding procedure wherein the compressed representation is recursively generated as successive sub-intervals within a predetermined interval. The width of each sub-interval is theoretically equal to the width of the previous sub-interval multiplied by the probability of the current symbol. The improvement is achieved by approximating the width of the previous sub-interval so that the approximation can be obtained by a single shift and add operation using a suitable shift register.
