Patent AU-648593-B2 (AU)
Title: Improved fastening device
Inventor: HUTCHINSON T GORDON
IPC: B42F3/00
Filed: 1991-09-16
Granted: 1994-04-28
Abstract: A fastening device or apparatus having at least two parts or components wherein reliance is on the deformation of an oval/ellipse shaped aperture which deformation results from the insertion of a stud component into the aperture which is formed within a socket component. The present invention permits the attachment of the two components and the release of such attached components both steps being achievable using the squeezing or pinching forces on only the periphery of so called socket component and exertable with the use of one hand; more specifically the use of the fingers of one hand. More particularly, the invention is very simply based upon the deformation by a substantially cylindrical shaped member of an oval or elliptically cross-sectioned aperture which results in forces, due to the deformation and due to the characteristics of the material in which the aperture in located, which cause the two components to interengage and the interengagement can be caused to be released by the simple squeezing or pinching of only the socket component using the fingers of one hand. The stud and socket components may be adapted to have a plurality of interengagement discs on the stud component and at least one recess within the aperture of the socket component which recess cooperates with one of the discs of the stud component to result in the interengagment of the two components when the stud component is inserted into the socket component aperture. Where there is more than one recess in the aperture of the socket component each of the recesses may interengage with one of the discs of the stud component. The resulting interengagement will be adjustable in that the stud portion will be more or less into the aperture and as the number of disc/recess interengagements increases so do the security of the connection of the two components increase. There may also be two "stud components" a first and a second which may be connected together end-to-end using a socket component adapted to interengage with each of the two stud components. The end-to-end interengagement may be made and released by the one hand deformation of the socket component - that is the changing of the aperture from ellipse to oval by squeezing parallel to the major axis and then releasing allowing the aperture to tend toward an elliptical shape which results in the engagement of the two stud components. Release is accomplished by simply squeezing along the major axis causing deformation of the aperture to the circular/oval cross section allowing the dissengagement of the stud components. The fastener of the instant invention can thus be engaged and disengaged having access to only the socket component.

Title: Plasmids for construction of eukaryotic viral vectors
Inventor: MCVEY DUNCAN L
IPC: C12N15/09
Filed: 1998-09-23
Granted: 2002-07-04
Abstract: The present invention provides a dual selection cassette (DSC) comprising first and second DNA segments having homology to a eukaryotic viral vector, positive and negative selection genes, each operably linked to their own promoter, and one or more unique restriction enzyme sites (URES) or sitey-directed homologous recombination sites. The present invention also provides a plasmid, pN/P, comprising an independent positive selection marker gene, an origin of replication, and a dual selection cassette. The dual selection cassette and pN/P plasmid can be used to produce eukaryotic gene transfer vectors without requiring temporally-linked double recombination events or the use of specialized bacterial strains that allow the replication of plasmids comprising defective origins of replication. This method usefully increases the ratio of desired to undesired plasmid and vector constructs. Additionally, this invention provides a method for the creation of eukaryotic viral vector libraries.

Title: Stepped bore type hydraulic booster - has master piston guided in bore of booster piston and subjected to reaction pressure
IPC: F15B9/10
Filed: 1969-02-13
Abstract: The hydraulic booster comprises a cylinder with bore of two different dias, the larger one accommodating a booster piston connected to one or more acutators, and the smaller one a master piston actuated by a pedal etc. The pressure-chamber, in which the pressure is formed thrusting the booster piston in the working direction, is connected either to the pressure supply or the return pipe via passages in both pistons and the housing, dependent on the relative position of the pistons to each other. The master piston is guided for part of its length in a bore in the booster piston. Its working face is always exposed to the pressure in the chamber formed by this bore and an annular chamber and which thrusts the booster piston in the working direction, so that this pressure can be felt as a reaction force opposing actuation of the master piston.

Abstract: A modular modular control apparatus for a water treatment system which periodically undergoes a regeneration cycle including a backwash phase and a replenishment phase. The modular control apparatus has a modular design which includes interchangeable timer modules, a drive motor module, a drive mechanism, a valve cartridge unit, a brine valve module and interchangeable brine valve levers. The timer modules are rugged and relatively inexpensive but are not adjustable. Thus, to adjust the predetermined interval between regeneration cycles, a different timer module is installed. The drive mechanism includes two camming elements which in cooperation with an interchangeable lever and brine line sealing module draw a brine solution from the brine tank to replenish the treatment media and refill the brine tank with water to form a new brine solution. The use of interchangeable brine valve levers allows the quantity of brine solution used to replenish the treatment media to be easily adjusted. The valve cartridge includes a spool valve member, an inner piston and a guide assembly, which together form a unitary valve cartridge. The valve cartridge can be removed as a single unit which facilitates the installation, removal and repair of the cartridge. The control assembly also includes a user friendly housing. The front housing member is povotable whereby the valve cartridge and the control modules located in the interior of the housing are accessible from the front of the modular control apparatus. The valve body includes a brine valve module which is removable as a unit form the valve body. The sealing module is also removable as a unit from the brine valve module. <IMAGE>
Patent JP-S6337519-B2 (JP)
IPC: H01L21/00
Filed: 1982-04-09
Abstract: A method of manufacturing packages for LSI chips starts with the usual steps of punching holes in green sheets, screening patterning paste (adapted to form cermet conductors or the like after firing) onto the green sheet, and inspecting the green sheets optically. Here, subsets of green sheets are then stacked and compressed into sublaminates. The sublaminates are then functionally inspected electrically. Inspection is done by means of electromechanical contact, scanning electron microscope like techniques, or by other means of irradiating the conductors to energize them for electrical measurement. Measurement may be made between pairs of terminals on only one side of the device being tested, or on both sides of the device. Beams can be applied both top and bottom from a single source or plural sources. Measuring instruments employ various electromechanical techniques as well as electrons, light used photoelectrically, ions, or pneumatic ion jets. Secondary electrons can measure the specimen's potential locally or change its charge. This method can also be employed for the purpose of inspecting other multilayer structures (such as large multilayer printed circuits formed on a plastic base) prior to final assembly of the conductors and the various substrates into a laminated support for electrical circuits. This testing process can also be applied after firing of patterned green sheets prior to plating, as well as after plating.

IPC: A61K33/18
Filed: 1988-04-01
Granted: 1998-08-13
Abstract: Known pharmaceutical preparations with iodine content in an (organic) solvent have high water contents. They cannot be stored for long times and often produce high local iodine concentrations in the application area, which result in skin irritations. They delay the operation due to their relatively slow evaporation, which is further uncomfortable for the patient due to the cooling effect. It is an object of the invention to overcome these disadvantages. The preparation according to the invention has only very small water content or is even completely non-aqueous. The preparation is storable for several years and evaporates very quickly on application without producing any excess local iodine concentrations. Unexpectedly, the non-aqueous preparation is thoroughly microbicidal in the 10-seconds range and further also kills spores quickly and with high efficiency.

Abstract: The present invention relates to a process for the one-stage resalting and purification of oligopeptides. Oligopeptides are often not formed directly as acetates when synthesised. Acetate salts of oligopeptides are however desirable as bulk-active material for medical and formulation reasons. Processes known from the prior art have hitherto involved two separate steps or pyridine-containing solvents. The resalting and purification can be combined in one step and the use of pyridine as solvent can be avoided, if the oligopeptide in the form of its chloride salt is purified with an acetate-containing solvent by liquid chromatography methods.

Abstract: An absorbent article having a topsheet and an absorbent core material. The acquisition distribution layer is located between the topsheet and the absorbent core material. The acquisition distribution layer is made of a three dimensional apertured film that defines a large void volume space between the acquisition distribution layer and the absorbent core material. The acquisition distribution layer provides high void volume for lateral spillage during repeated insult moments because the topsheet, which is in contact with the user, is held away from dispersing fluid that is unabsorbed by saturated core material. The void volume space provides a pathway for unabsorbed fluid to flow over the top plane of saturated core regions to unsaturated regions of the core material for absorption. The void volume space allows this migration of fluid to occur without the fluid coming into contact with the topsheet, thereby avoiding a feeling of wetness for a wearer.
