Title: Method and apparatus for implementing adaptive forward differencing using integer arithmetic
Inventor: CHANG SHEUE-LING L
IPC: G06F5/01
Filed: 1989-08-14
Granted: 1993-07-20
Abstract: ABSTRACT OF THE INVENTION              A method and apparatus for implementing adaptive forward differencing technique in integer arithmetic resulting in an increase in precision while minimizing the number of mathematical operations to be performed is disclosed.  The method and apparatus of the present invention provides for using a floating binary point adaptive forward differencing technique in which the binary point of the forward difference register, containing the value of theparametric function, is not shifted during parameter adjust-up and adjust-down operations.  The binary point of the succeeding forward difference registers each containing a value corresponding to succeeding higher order derivatives of the parametric functions, are initially shifted a number of bits equal to a predetermined number of bits 'N' multiplied by a multiplication factor (referred to as guard bits) and the binary point is shifted to the right by one bit when an adjust-up operation is performed and to the left by one bit when an adjust-down operation is performed respectively reflecting the removal of a guard bit when an adjust-up operation is performed and the addition of a guard bit when an adjust-down operation is performed.

Title: Identification system using information-carrying signals on a portable object, such as a key and a signal detecting apparatus
Inventor: SAMOKINE GEORGES
IPC: H04Q9/00
Filed: 1989-08-23
Granted: 1993-10-26
Abstract: The exchange device (not shown) is installed in a lock and emits a modulated carrier wave. The key (2) possesses circuits (27, 28, 29, 23) for demodulating the modulated carrier wave received and for reconstructing a first signal (PR) representing the information emitted by the exchange device, and processing circuits (23, 25, 30) receiving the first signal (PR) and generating a second signal (D) representing the information to be transmitted. The second signal causes an impedance (26) to vary abruptly, so that the charge detected by the exchange device varies and so that the information is thereby transmitted to it. Moreover, the impedance (26) is designed as a limiter. A clock signal (41) is obtained from the modulated carrier wave by clipping, and the supply voltage (AC) is obtained by rectification and regulation. The system makes it possible particularly to use a contactless connection between the key and the lock, for example by means of a single pair of coils. <IMAGE>

Granted: 1993-04-27
Abstract: ABSTRACT OF THE DISCLOSURE            A  pivoting  support  for  chairs,  seats  and  the  like comprises a main support member which is connected to the base  structure of the chair and a seat support member   which  is  pivotably  connected  to  the  main support member  with the interposition of an auxiliary support member.  The latter is articulated to the main support member about a first horizontal axis and to the seat support member about a second horizontal axis parallel to and in front of the first horizontal axis. First resilient means are interposed between the main support member and the seat support member for biassing the seat support member towards a position in which it is rotated upwardly relative to the auxiliary support element.   Second resilient means are also interposed between  the main  support member   and  the  auxiliary support  member  for  biassing  the  auxiliary  support member  towards  a  position  in  which  it  is  rotated upwardly relative to the main support member.  The user can pivot the seat backwards by downward rotation of the  seat  support element  relative  to  the  auxiliary support element,  overcoming the action of the first resilient means, or forwards by downward rotation of the  auxiliary  support  member  relative  to  the  main support member, overcoming the action of the first and second resilient means.

Granted: 1994-03-29
Abstract: ABSTRACT      A method and apparatus provide for the continuous digestion of comminuted cellulosic fibrous material (e.g. wood chips) to produce paper pulp, with increased sulfidity.  When black liquor is withdrawn from the continuous digester, instead of merely passing it to a pair of flash tanks and then to recovery, the concentrated liquor from a first flash tank is fed to a vessel in which the comminuted material is slurried with a liquid.  Since the black liquor remains in intimate contact with the chips for a significant period of time, the lignin in the chips is partly sulfonized.  Ultimately the black liquor is replaced with white liquor or the like, and the separated out black liquor is circulated to recovery or disposal.  A high pressure feeder and a solids/liquid separator are utilized.

Abstract: A method and apparatus are provided for increasing the efficiency of treatment of a paper pulp slurry with chlorine gas, such as in the bleaching or delignification of deciduous wood chemical pulps, coniferous wood chemical pulps, and non-wood fibrous chemical pulps. Chlorine gas is intimately mixed with the pulp in a fluidizing mixer (14), the pulp preferably having a consistency of about 7-12%, and then is passed to a retention vessel (20). The discharge of pulp from the mixer to the retention vessel, and from the retention vessel to other treatment structures, is throttled by valves (30, 31) so as to increase the pressure in both the mixer and the retention vessel to above atmospheric, and preferably in the range of about 15-150 psig (1 to 10 bar above atmospheric pressure). The chlorine gas is added to the mixer through one more discs (53) of porous materials having pore sizes in the range of about 5-175 microns, such as porous ceramic or sintered metal discs. The increased pressure during the chlorine treatment, and the introduction of the chlorine gas in the form of minute bubbles, improve the solubility of the chlorine in the pulp slurry and thereby increase the efficiency of treatment.

Abstract: The present process produces the meso dialkyl 2,5-dihaloadipate from a mixture of the racemic dialkyl 2,5-dihaloadipate and meso 2,5-dihaloadipate. In the disclosed process, a 2,5-dihaloadipoyl halide is formed under conditions which result in the formation of an acidic compound. The 2,5-dihaloadipoyl halide is then esterified under conditions wherein the ester of the dihaloadipoyl halide is allowed to remain in contact with the acidic compound, thus allowing the racemic diester to epimerize in the presence of the acidic compound to the meso form and then the meso diester spontaneously crystallizes. In the last stage, the meso diester produced is removed.

Abstract: A protective safety container (10) for encasing toxic drug filled glass vials (18) is disclosed. The container includes a molded plastic body (12) that is shaped to conform to the shape of a vial to be protected. A plurality of spaced longitudinal ribs (32) are formed on the inner surface of the container body (12) that act to engage the vial (18) and hold it firmly in position, and also form a cushioning air space between the vial and the container. A molded plastic annular base (14) is adapted to be snap fitted into the body (12) such that the vial (18) cannot be easily removed once it is secured within the container. Disposed in the top (15) of the container is a small aperture (26) having a frangible disk (28) disposed therein. The disk (28) may be removed so that a hypodermic needle may be inserted into a stopper (19) in the vial (18) to withdraw the vial's contents. The aperture (26) is too small, however, to permit removal of the stopper itself. All of these features combine to provide a protective container for a glass vial which will prevent the intentional or accidental discharge of the vial's contents to the surrounding area.
