Title: Separation process of zeolites
Inventor: CARATI ANGELA
IPC: B01J20/30
Filed: 2001-12-18
Abstract: The object of the present invention relates to a simple, rapid and inexpensive process for effecting solid-liquid separations in the case of zeolites, also having small crystals. This process, which is particularly useful for the recovery of zeolite crystals in suspension in the crystallization water, comprises treating this suspension of crystals with an acid or one of its precursors and subjecting the resulting mixture to filtration or decanting. According to a particular aspect of the invention, the crystalline phase is separated in a mixture with oxides which can be used as ligands. Said oxides can be generated by the reagents of the zeolite preparation reagent mixture, not transformed into crystalline phase during the synthesis hydrothermal treatment, or they can be added to the suspension of crystals before the separation treatment, or again they can be generated by precursors suitably added to the crystallization slurry.

Inventor: BROCK DAVID A
IPC: G01N33/558
Filed: 2000-02-18
Abstract: Disclosed is an improvement to a dry assay device
for determining the concentration of a first analyte
in a sample of body fluid and a second analyte in the
same sample of body fluid. The device involves the
use of a strip of an absorbent material through which
the sample of body fluid flows and wherein the first
analyte is determined colorimetrically in a first region
of the strip and the second analyte is determined
by an immunoassay which takes place in a second region
of the strip located downstream from the first region.
The improvement involves placing the strip in a hollow
casing having a top and a bottom and which is so constructed
that when the top and bottom of the casing
are mated there is formed a U shaped, body fluid impervious
barrier around the first region of the strip
to prevent the sample of body fluid from flowing in
any direction other than in the direction of the second
region of the strip.

Abstract: The invention provides a lead frame size requiring a
reduced area, and a package reduced in size. Adjacent light
couplings (4) have an insulating and light shielding element
(5) disposed therebetween to block a light transmission from
one to the other. The insulating and light shielding element
allows the light couplings to be arranged close together while
preventing crosstalk occurring therebetween. In another
construction, a primary light coupling section and a secondary
light coupling section are formed around each light emitting
element on the primary side and each light receiving element
on the secondary side. The primary and secondary light coupling
sections are optically interconnected through an insulating and
light transmitting element. This construction realizes
optical paths of reduced volume, and secures a sufficient
distance for preventing crosstalk even where adjacent light
couplings are arranged with a reduced distance therebetween.

Abstract: A centrifugal braking mechanism is a device for
braking a spool (12) that is rotatably supported in a reel body (1).
The braking mechanism uses centrifugal forces in order to
produce braking force against rotation of the spool (12). The
braking mechanism (23) includes a plurality of brake members (53), a
brake housing (52) having a cylindrically shaped brake liner,
and an adjusting mechanism. Each of the plurality of brake
members (53) is configured to move in a radially outward
direction relative to the spool in response to rotation of
the spool (12). The brake housing (52) and brake liner (57) are moveable
in an axial direction relative to the spool (12) and brake
members (53) such that any selected number of the brake members (53)
may contact the brake liner to generate the braking force.
The adjusting mechanism is used to selectively move the
brake housing (52) and brake liner (57) into any of a plurality of
axial positions thereby determining the number of brake
members (53) that are contactable with the brake liner (57) in
response to centrifugal force. The level of braking force
desired is determined by the number of brake members (53) that
may contact the brake liner (57).

Abstract: FM demodulation and decoding in a fixed point DSP is
disclosed. The fixed point DSP must carry out division and
arctan calculations for which there is no dedicated hardware.
Division is normally achieved either by using the Newton-Raphson
method or by using "conditional subtraction'
instruction. Another and faster technique is to use a table
look-up approach. However, in a table look-up, if the
denominator value is very small, the size of the table look-up
will be large. The present invention manipulates the in-phase
representation of the denominator to overcome the table look-up
problem by adding the integer two (2) to the value of 1/RL
(34) to obtain 1/RL+2 before using the look-up table (36) to
reduce the instruction cycle time. In addition, for decoding,
the invention uses an efficient implementation of pilot
frequency computation by choosing DFT snapshot value (46) at
0°, 90°, 180°, 270° and 360° to reduce the number of
multiplication steps.
