IPC: F16D65/56

Abstract: The present invention relates to a brake actuator for use in a disc brake, the brake actuator incorporating an automatic adjuster mechanism to take account of friction pad wear. In certain known brake actuators a clutch mechanism comprising one or more clutches is used to provide for the required control of the rotational movement of a threaded adjuster sleeve (19) in which a tappet (21) is located. These clutches are located around the outside surface of the adjuster sleeve (19) and thus, due to overall spatial require­ments within the actuator (1), the outside diameter of the adjuster sleeve (19) and as a result, the diameter of the threaded bore in the adjuster sleeve (19), have to be limited in size. The threaded tappet (21) thus comprises an enlarged diameter head region and a reduced diameter threaded region. Due to the limited diameter of the tappet (21), the tappet (21) can tilt or be damaged, resulting in premature and/or even pad wear. 
     The present invention provides a brake actuator comprising a drive shaft 93) rotatably supported in an actuator housing (1) and coupled to an internally threaded adjuster sleeve (19) by coupling means (7) which convert rotational movement of the drive shaft (3) into axial movement of the adjuster sleeve (19). The internally threaded adjuster sleeve (19) is retained against rotational movement and is screw threadedly engaged with a hollow tappet (21) within which a clutch mechanism (23, 35) for interconnecting the drive shaft (3) and tappet (21), is located. The clutch mechansim (23, 25) is thus located within the hollow tappet (21) so that the diameter of the threaded connection between the tappet (21) and adjuster sleeve (19) can be optimised to at least reduce the problems of premature and uneven pad wear inherent in previous constructions.

Abstract: An isolator and method of using it for providing a contamination-free atmosphere in which a surgical procedure can be performed or equipment that is sensitive to environmental contamination can be assembled. The isolator includes an inflatable bag (10) of flexible material through which filtered air is pumped to continuously change the air and maintain a positive pressure in the bag. For use in surgery, a portion of the lower side is made of a surgical drape material (30) of elastic material to allow a body member upon which a surgical procedure is to be performed to be pulled into the work space of the bag through an incision in the drape that is smaller than the member to cause the stretched elastic material to tightly surround the member and reduce the chances of disease organisms from entering the work space from outside the bubble.

Abstract: Les circuits intégrés utilisés dans une technologie à porte isolée (p.ex. CMOS) ont été protégés contre une décharge électrostatique (ESD) par un transistor à effet de champ à porte métallique. Il a été établi qu'un transistor bipolaire ''parasite'' existe en parallèle avec le dispositif à porte métallique. De manière surprenante, on obtient une protection supérieure en supprimant la porte métallique, pour ne compter ainsi que sur la charge d'avalanche du dispositif bipolaire pour la protection de polarité opposée. On a considéré comme établi que l'effet de champ du dispositif de porte métallique limitait de manière indésirable le passage de courant dans la technique de l'art antérieur. La technique de l'invention peut être mise en oeuvre de manière avantageuse en utilisant une diode plutôt qu'un transistor comme élément protecteur.

Abstract: A sample of biological medium liable to be contaminated by viral particles is first of all treated to digest the nonviral DNA and RNA nucleic acids and to preserve the viral nucleic acids. The sample is then purified, if appropriate, for example by being passed through a cartridge (32) containing a gel for retaining the proteins present in the sample. The viral nucleic acids are then extracted and denatured in the presence of an extraction medium in a storage vessel (62). They are then collected and then detected by an appropriate process, for example by a colorimetric process. The invention makes it possible to carry out in a particularly simple manner the polyspecific detection of the viral genomes containing DNA and RNA, especially in biological media such as serum. <IMAGE>

Date Nov. 3, 1988.Especially in gripper, insertion and bending tools of automatic insertion machines for electric components, the problem arises, that the production flow is adversely influenced because of solder accumulations at the tools. In machine design it is already known to apply hard material layers on a nitride base to improve tool surfaces; normally, better solder resistance is expected of them. According to the invention at least one second layer is provided as the cover layer with solid-lubricant properties, besides the nitride base layer. The base layer has here preferably a gradual change from high density in the boundary region to the base material of the tool to a porous rough structure at the boundary surface to the cover layer, where the change of the density can be continuous. The metal-nitride layer is advantageously a titanium nitride. With such coatings, the service life of the tools can be increased by more than one order of magnitude.
