Title: Process of regenerating a high-boiling scrubbing solution which contains co2 and h2s
Inventor: FRITZSCHE HANS-JOACHIM
IPC: B01D53/14
Filed: 1990-05-22
Granted: 2000-08-08
Abstract: The scrubbing solution has a boiling point above 100°C under atmospheric pressure and is used for gas purification at temperatures from 5 to 70 °C and is thus laden with at least CO2 and H2S. For regeneration, the laden scrubbing solution under a pressure of at least 2 bars and at a temperature of at least 60°C is supplied to an expansion zone and is expanded therein, A flashed-off gas which is rich in H2S is withdrawn from the expansion zone. The scrubbing solution from the expansion zone is subjected to a hot regeneration, by which the scrubbing solution at a temperature below its boiling temperature is stripped with an inert gas so that its residual loading is substantially removed. Mixed gases which contain inert gas are withdrawn from the hot regeneration and are contacted with scrubbing solution.

Title: No-twist slit-rolling approach ("nta") apparatus and method  for manufacturing steel reinforcing rod
Inventor: PONG DAVID TENG
IPC: B21B13/12
Filed: 1991-02-01
Granted: 1999-06-01
Abstract: A no-twist ("NTA") apparatus and method for manufacturing steel reinforcing bar which allows steel reinforcing bar to be manufactured with greater speed and precision than by conventional methods.  The NTA method employs numerous stands, with the shafts of the rolls of the first two stands offset 45° from a predetermined plane and 90° from each other.  The third and fourth stands comprise rolling and splitting stands and the shafts of their rollers are perpendicular or parallel to the predetermined plane and form equal angles with the shafts of the first two stands so that the bar can be fed to the rolling and splitting stands without intermediate twisting and the single bar can be split into a plurality of bar segments.  The remaining stands are arranged into at least two lines of stands, in each of which the sides of the rolls of the first stand are offset 45° in a first direction from the predetermined plane and the sides of the rolls of the second stand are offset 45° in a second direction opposite to said first direction relative to the predetermined plane.  Alternatively, the sides of the rolls of the first and second stands in the two lines are respectively offset either by 90  and 0° or 0° and 90°.

Title: Pressure limiting valve with teflon seal
Inventor: VOSS RICHARD
IPC: F16K17/04
Filed: 1990-07-27
Granted: 1996-03-05
Abstract: A pressure limiting valve (1) with flow rates of 2000 litres per minute and over has a valve piston (10) in the form of a tubular sleeve (20).  With the attached control piston (60), this valve piston (10) forms a structural unit in which the control piston (60), the diameter of which is correspon-dingly smaller, is loaded by means of a spring plate (26) and a valve spring (11) which is adjustable and predetermines the force at which the valve (1) opens.  The specially stepped construction of the valve piston (10) and its large diameter are possible because use is made of special kinds of sealing rings (19, 51 and 75) bearing on the outside on the large-diameter valve piston (10) and on the control piston (60) without hampering their movement significantly through fric-tion.  A good seal is nonetheless ensured because the sealing rings used (19, 51, 75) are very hard but create little fric-tion and lie closely against the valve piston (10) and the control piston (60) owing especially to the construction of the annular groove (50, 55 and 76) with a bevel (54, 58, 77).

Patent CA-2047897-C (CA)
Title: Beam scan velocity modulation apparatus
Inventor: ALTMANSHOFER ROBERT DALE
IPC: H04N3/32
Filed: 1991-07-25
Granted: 1995-12-26
Abstract: In a beam scan velocity modulation (SVM) system for a television receiver, a video signal is applied to a differentiator followed by a limiting differential amplifier. A driver amplifier coupled to the limiting amplifier drives an output stage that supplies current to an SVM coil. Certain video signals with large high frequency content may tend to produce excessive dissipation in the devices of the output stage. To prevent this, a current source for the differential amplifier is controlled by a voltage obtained from a current sampling resistor, which voltage is a measure of the average current through the output stage. The magnitude of the current source is varied by a current limiting feedback circuit to thereby vary the peak-to-peak signal output from the limiting amplifier to prevent overdissipation of the output devices. The driver amplifier performs a coring operation that is unaffected by the variable limiting.
Patent CA-2055987-C (CA)
Inventor: KESSLER WILLIAM KURT
IPC: H04M1/57
Filed: 1991-11-21
Granted: 1995-08-22
Abstract: Telephone call identification service that safeguards the privacy of an originating station (calling party), while providing useful identifying information to a destination station (called party), is achieved by an encryption process. The encryption process includes combining the originating number with the telephone number of the destination station to form a message. Thereafter, the message is encrypted using the Data Encryption Standard (DES) or the Rivest, Shamir, Adleman (RSA) encryption algolithm to form ciphertext which is transmitted to the destination station. Using either encryption process, the ciphertext is reversible. A telephone switching office, preferably equipped with an electronic program-controlled switching system, executes the encryption algorithm and safeguards the keys used for encryption and decryption. When reversibility of the ciphertext isdeemed to be undesirable, the telephone switching office uses modulo n processing of the ciphertext to render it non-reversible.

Title: Method for reproducing conifers by somatic embryogenesis
Inventor: PULLMAN GERALD S
IPC: C12N5/04
Filed: 1990-10-22
Granted: 1997-12-30
Abstract: The invention is a method for reproducing coniferous trees by somatic embryogenesis using plant tissue culture. It comprises a multistage process in which a fertilized immature-embryo is excised and cultured to induce early state proembryos, which may be further cultured in liquid media without auxins or cytokinins but with the addition of abscisic acid, to develop late stage proembryos. In some species, it is desirable to significantly raise the osmotic potential of the late stage development medium. The medium may have added exogenous abscisic acid and must contain an absorbent material. After several weeks in culture the vigor and morphology of the embryos developed by the process are improved and the tendency of premature germination is reduced. The somatic embryos may be germinated before or after storage and transplanted to soil for further growth.

Granted: 1996-11-12
Abstract: A system for creating and modifying intelligent tele-phone network call processing logic trees which can be custom-ized for individual customers and created in a user-friendly vis-ual environment (10, 15, Fig. 3-5). Service primitives are de-fined as logical graph nodes (20, Fig. 2, Fig. 3) which can be visually assembled into logic trees (Fig. 5) which represent the service logic flow and which provide default values for all ser-vice options. Higher level nodes, assembled from a plurality of service primitives, can likewise be defined and stored (12, 13, 19) for later use as entities in defining yet further call process-ing logic trees. These call processing logic trees are interpreted to allow the service control point computers (17) to implement the services in the switched telephone network (18) by sequen-tially executing the specified call processing primitives. A lib-rary (12, 13, 19) of defined nodes and defined node assemblies which represent service features can thus be made available to permit graphical manipulation into complete logic trees repres-enting new services. These logic trees are then interpreted by generic programs in the service control point to actually pro-vide the described services.
