Title: Process for making metal dental restorations
Inventor: HORNIG WOLFGANG
IPC: A61C13/00
Filed: 1987-03-05
Granted: 1991-12-17
Abstract: A PROCESS FOR MAKING METAL DENTAL RESTORATIONS                ABSTRACT OF THE DISCLOSURE The process for making metal dental restorations consists in that an impression of the tooth or jaw to be treated is prepared using an electrically non-conductive materiel, the inner wall of said impression is coated with a heated low-melting alloy and then the interior is filled up with filling material in which fixing pins are inserted in the case of crowns, inlays and bridges. Alternatively, the impression is filled up with tradiational filling materials and an electric conductive coating is produced by vaporizing a metal layer, spraying a conductive lacquer or currentless deposition of an electrically conductive layer.  Again, alternatively the impression may be filled up with electrically conductive plastic.  The replica of said tooth so produced is separated from the impression, and there is galvanically applied an intermediate layer of a base metal after which one or more layers of high-melting point noble metals are galvanically applied to the intermediate layer, the filling material, the innermost electrically conductive layer and the intermediate layer first being then removed and, if desired, porcelain and/or plastic is applied as facing or substitute teeth on the dental restorations thus resulting.

Granted: 1991-07-16
Abstract: VEHICLE RESTRAINT HAVING AN UPWARDLY BIASED RESTRAINING MEMBER     Abstract of the Disclosure A vehicle restraint for preventing accidental movement of a vehicle away from a loading dock.  The vechicle restraint comprises a frame mounted on the front face of the dock and a restraining member having a hook like configuration is mounted for movement on the frame between the lower storage position and an upper operative position where the restraining member is engaged with an abutment, such as an ICC bar, on the vehicle.  The restraining member is biased upwardly to the operative position and a power operated means is arranged to move the restraining member downwardly from the operative position to the storage position where it is locked in the storage position by a releasable latching means.  On release of the latching means, the biasing mechanism will move the restraining member upwardly into engagement with the ICC bar, and the biasing means enables the engaged restraining member to follow both upward and downward movement of the ICC bar during a loading operation.

Title: Variable speed generator-motor apparatus
Inventor: BANDO AKIRA
IPC: H02P9/00
Filed: 1988-08-12
Granted: 1991-09-17
Abstract: Abstract A generator-motor apparatus has economical protection measures for use in a variable speed pumping-up electric power plant.  The apparatus comprises a main transformer, a secondary winding of which is coupled to an electric power system, a power system breaker connected to a primary winding of the main transformer, and a synchronizing breaker connected in series with the power system breaker.  The generator-motor has a rotor mechanically coupled to a pump-turbine and an armature winding connected to the power system through the synchronizing breaker, the power system breaker and the main transformer.  An excitation circuit, including a frequency converter, supplies a field winding of the generator-motor with an AC voltage of variable frequency. A converter transformer for feeding the converter is branched from a function of the power system breaker and the synchronizing breaker.  The arrangement is such that the power system breaker does not need to have such a large current breaking capacity as the excitation breaker employed in prior art arrangements.

Title: Composition useful in process for preparing powadir membranes from tetrahalobisphenol a polycarbonates
Inventor: BECK HENRY N
IPC: B01D53/22
Filed: 1988-09-19
Granted: 1994-10-04
Abstract: ABSTRACT       The invention is a semi-permeable membrane which comprises a polymeric matrix with two porous surfaces and a region which functions to separate one or more gases from one or more other gases.   A composition is disclosed that is useful for the preparation of of a bisphenol-based polycarbonate membrane wherein at least 25 percent by weight of the bisphenol moieties are tetrahalogenated, preferably Cl or Br.  The composition includes (i) a bisphenol-based polycarbonate wherein at least 25 percent by weight of the bisphenol moieties are tetrahalogenated, wherein the halogen is Cl or Br, (ii) a solvent for such polycarbonate, and (iii) a non-solvent for such polycarbonate.       A process is described  wherein the composition is heated and extruded into a shape suitable for membrane use such as a hollow fiber.   The formed membrane is then passed through a quench zone wherein the mixture undergoes phase separation, and the solvent non-solvent are removed and a discriminating region capable of separating oxygen from nitrogen is formed. The membranes of this invention exhibit excellent separation factors and flux.  Such membranes are less prone to being damaged due to handling and exposure to contaminants due to the internal region which affects the separation, as the porous surfaces function to protect such region.

Date Jun. 29, 1989.A device for taking samples of arterial blood with a view to its subsequent gasometric analysis comprises a main body forming a reservoir in which a free piston travels. Said piston isolates the blood from the air and cannot be manipulated by the operator. The device also includes a filter located at the end of the piston stroke which is permeable to air and impermeable to blood, allows the operator to observe the blood as it advances, and acts as a barrier to excessive blood flow, and a stopper which ulitmately seals the system and facilitates its tranport. In contrast to conventional invasive systems, this device, which does not need to be sterilized, makes it possible to obtain a blood sample which, after sampling, is only minimally contaminated with the ambient air, is available in a sufficient quantity, and is only slightly coagulable.
