Abstract: ABSTRACT OF THE DISCLOSURE         A method for forming cellular shades using sheer materials.  Strips of sheer material are creased to define tabs and central portions.  Strips of a non-bonding material are placed over the central portions.  Beads of adhesive are placed over the tabs and these assemblies are stacked, whereby the tabs are adhered to the central portions of the successive strip, while the non-bonding material prevents adhesion of the tabs to the central portions of the corresponding strips.  When the adhesive has set, the non-bonding strips can be conveniently removed, yielding a cellular shade which can be formed of substantially any fabric material.

Abstract: ABSTRACT OF THE DISCLOSURE    The present invention is directed to the elimi-nation of ascorbic acid interference in assay sys-tems, particularly assay systems based upon oxidase-peroxidase coupled reactions.  When ascorbic acid is present in a sample, it can act as a reductant thereby interfering with an assay's reagent system. The present invention eliminates this interference by quickly oxidizing any asceorbate thereby preventing ascorbate from acting as an unwanted reductant.  The ascorbate is oxidized using a dual oxidant system comprising a water soluble polymer bound to Cu+2 and an organic or inorganic oxidant such as chromate, peroxide, or a N-halo derivative.  This invention is surprisingly selective and generally will not itself interfere with the assay's reagent system.  Further-more, the present invention is so fast and efficient that it can be incorporated into a convenient format, such as a conventional "dip-and-read" reagent test strip system.

Abstract: A damping circuit is described for the antenna resonance circuit (28) of a radio transmitter-receiver (10) which in a transmitting phase transmits a time-limited high-energy interrogation pulse and in a receiving phase following the transmitting phase is ready to receive high-frequency response signals coming from a responder (26) which transmits said response signals as reaction to the reception of the interrogation pulse.  In the damping circuit (24) a damping member (R4, R5, R6) is provided which is adapted to be connected to the antenna resonance circuit and disconnected therefrom.  A switching means (T4, T5) on receiving a switching voltage applies the damping member (R4, R5, R6) to the antenna resonance circuit (28).  A first energy-storage element (Cl) chargeable by the HF interrogation pulse serves for furnishing the switching voltage and a second energy-storage element chargeable by the HF interrogation pulse in dependence upon the time profile of the HF interrogation pulse enables the application of the switching voltage present at the first energy-storage element to the switching means (T4, T5).

Title: Dental handpiece assembly
Inventor: MARTENS LESLIE V
IPC: A61C1/05
Filed: 1990-09-18
Abstract: ABSTRACT OF THE DISCLOSURE     A gas driven medical or dental handpiece assembly of the type having a turbine driven dental tool.  A sterile coolant supply is usable with the handpiece to provide liquid fluid under pressure to irriagate the patient site and cool the dental tool.  The coolant fluid is derived from a cartridge connected to the handpiece.  The cartridge is replaced for each patient.  The cartridge is divided by a flexible diaphram into a propellant chamber and a liquid chamber.  Initially the liquid chamber is full and the propellant chamber is empty with virtually a volume of zero.  A propellant gas under pressure is introduced into the propellant chamber of the cartridge to displace the diaphram and move the liquid through a fluid conduit to the tip of the handpiece.  The propellant is derived from a portion of the compressed gas used to drive the turbine.          Another portion of the compressed gas is diverted to a chip air conduit of the handpiece.  The handpiece assembly eliminates the use of the conventional common water supply as irrigant or coolant fluid.  Use of the removeable fluid cartridge allows sterilization of the entire handpiece eliminating much of the risk of cross contamination between patients.

Abstract: ABSTRACT   The apparatus consists of a casing (1) and a rotating cover (2) with baskets (5) to hold the contact lenses which are to be cleaned. The rotating cover (2) is set on the casing (1) by means of a guide rod (6). The contact lenses are first lowered into a tub (9) in the casing containing a cleaning and disinfecting solution (3). After an adjustable amount of time, the rotating cover (2) is pushed up by a push rod (7). The tip of the push rod (7) is guided down a helical groove (12), thus rotating the cover by 180°. At the end of its path, the push rod ends up in a hole (24) and the contact lenses are thus lowered into the tub (8) containing the neutralization solution.

Title: Process for making a possibly flat synthetic resin moulded block and preform for use in such a process
Inventor: HAUNOLD FRITZ
IPC: B27K3/24
Filed: 1990-04-27
Abstract: (57) Abstract In a process for making a synthetic resin moulded block from fibres containing cellulose like wood fibres and a condensa-tion resin binder like phenolic resin, for the continuous production of a mould blank or plate, a layer (19) of the viscous binder is applied on a web-like conveyor (2), especially a paper impregnated with phenolic resin, and a fibrous mass is then applied to it in the form of a fibre cake (20. A second coated web of conveyor material (7) is then continuously laid upon the fibrous mass with the coating of binder (26) downwards, whereafter the laminated structure (27) thus obtained is heated and compressed in a heated strip press (10), whereby the binder is distributed generally uniformly on the porous volume of the laminated structure. After the compressed laminated structure (27) has cooled it is used as the preform for the production of high-pressure moulded blocks. In another embodiment of the process, the laminated structure may be directly converted into a synthetic resin  moulded block by in-creasing the pressure, pressing temperature and the time in the strip press with the curing of the binder.
