Title: Contact Lens Cleaning and Disinfecting System
Inventor: BOROVSKY SIMCHA
IPC: G02C13/00
Filed: 1992-07-17
Abstract: A contact lens cleaning and disinfecting system is formed as a compact unit with an upper housing portion (1) containing a UV lamp and a lower base portion (2) containing a cleaning/disinfecting chamber (15, 16) which is filled with saline solution, a lens holder (14), a turbulence mechanism (17, 19, 20a) for inducing turbulence in the fluid, and an electronic control unit (21) for operating the UV lamp and the turbulence mechanism in a single cleaning/disinfecting cycle of comparatively short duration.  The lens holder (14) has a pair of lower lens holder portions (14a, 14b) for the lenses and an upper bracket (14c) for shading the lenses from direct UV radiation.  The turbulence mechanism has a magnetic pedal (20a), tethered on the end of a flexible spring (20b). The pedal is driven by a magnetic flux generator (19) in a subsonic oscillation range to create a whirlpool in the fluid which swirls in and around the lens holder portions. Particles, films, and other deposits dislodged from the lenses are carried by the whirlpool above the upper bracket of the lens holder where they are disinfected by the UV radiation.  The UV disinfecting and turbulence cleaning avoids the need for any manual scrubbing, heating of the lenses, detergents, preservatives, or disinfectant chemicals.

Title: Mechanism and Method for Allocating Active Objects on a Processor Stack
Inventor: KALAS IVAN
IPC: G06F15/00
Filed: 1994-02-11
Abstract: MECHANISM AND METHOD FOR ALLOCATING ACTIVE        OBJECTS ON A PROCESSOR STACK     When an object call from the stack results in the invocation of a hierarchy of class constructs also on the stack, a base class removed more than a predetermined number of levels from the derived class whose member object was called, has no means of directly accessing the originating program to implement an independent task outside the invocation chain. After determining that the data object is constructed on the stack,  a mechanism is provided for following the chain of pointers found in the stack frame link records to directly access the originating activation record in the stack for base classes having independent task constructors.

Title: Locking and unlocking apparatus for access door on a passenger railway vehicle
Inventor: BRILLANT DANIEL
IPC: E05B51/02
Filed: 1994-06-13
Abstract: An  apparatus  for  mechanically  locking  and  unlocking  a passenger access door panel on a railway vehicle which includes a locking lever arm, one end of which is pivotally secured to a movable door panel and having a roller secured at the opposite end, and having a biasing means to pivotally bias the roller against a locking support structure secured to a structure adjacent to the movable door panel when such door panel is moving into the closed position.  The locking support structure has a first rail surface at an inclined angle to the door panel anda second rail surface which is substantially perpendicular to the door panel and is positioned so that the roller on the locking lever arm will roll along the first inclined rail surface when the door panel is moving into the closed position, and such that when the door panel reaches a fully closed position, the roller will move beyond such first inclined  rail  surface  and  be  biased  to  move  against  the perpendicular rail surface to thereby lock the door panel in the fully  closed  position.    The  apparatus  further  includes  an unlatching lever assembly that will pivot the locking lever arm and roller away from the perpendicular rail surface in response to automatic controls activated by a door opening mechanism, or in response to a manual controls.

Inventor: UCHIMURA MITSUO
IPC: B22D11/11
Filed: 1994-08-30
Abstract: A semi-solidified metal composition having an excellent workability is continuously produced by pouring molten metal into an upper part of a cooling agitation mold, agitating it while cooling to produce a slurry of solid-liquid mixed phase containing non-dendritic primary solid particles dispersed therein and discharging out the slurry from a lower part of the cooling agitation mold.  In this case, a ratio of shear strain rate at a solid-liquid interface to solidification rate of molten metal is adjusted to a value exceeding 8000 in the cooling agitation mold.

Abstract: 2133341 9319995 PCTABS00027 A sealing system of the type in which a locking pin is received in a cavity containing a tooth that cooperates with the pin to prevent withdrawal of the pin. The object of the invention is to provide this type of seal but which is at the same time both of high security and simple to manufacture. In the system of the invention, the cavity (2) has two openings (14, 16) adjacent to each other and separated by the base (17) of the tooth (18). The cavity is otherwise totally closed and its inner wall (21), which extends to the bottom of the cavity, is curved under the base (17) of the tooth. This permits manufacture using an injection mould having a plate (39) provided with a fixed part (40) and a part (41) rotatably mounted on the fixed part to define therebetween the male mould portion for moulding a cavity with a tooth. An actuator (42) serves to rotate the rotary part (41) during opening of the mould, the rotary part (41) having a curved surface (52) corresponding to the curved part of the inner wall (21) of the cavity.  Security seals and devices incorporating the new sealing system are also described.

Title: Method and apparatus for froth flotation
Inventor: YALCIN TURGUT
IPC: B01D1/14
Filed: 1995-01-16
Abstract: A mineral flotation device used for separating fine particles of hydrophobic minerals from a ground ore pulp by making them attach to air bubbles inside a vertical cylindrical column into which a mixture of air and said ore pulp is pumped either tangentially or axially at the bottom. Tangential pumping generates a centrifugal force field which facilitates the formation of air bubbles and subsequent bubble-particle attachments. With axial pumping, air bubbles are produced either by letting the said mixture impinge on a baffle uponentry into the said cylindrical column or by pumping the said mixture through a nozzle. The froth products formed from bubble-particle aggregates are removed by various means depending on the type of application and the desired outcome. Fast flotation is obtained by immediate discharge of the froth formed. Clean froth products are obtained by passing the froth through an expanded or wide froth column and through a magnetic field.
