Title: Treatment of gas streams
IPC: C01B17/04
Filed: 1988-05-02
Abstract: A first hydrogen sulphide containing waste gas stream from an oil refinery is combusted in a first combustion chamber 16 using pure oxygen to support combustion. The combustion products are cooled in heat exchanger 20, and a part of the combustion products are recycled to the chamber 16 to moderate the temperature therein. The remainder of the combustion products are mixed with a second hydrogen sulphide containing waste gas stream of different composition from the first stream. A proportion of the hydrogen sulphide content of the mixed stream is combusted in combustion chamber 28 again using pure oxygen to support the combustion. The resulting sulphur dioxide reacts with residual hydrogen sulphide to form sulphur vapour.
Patent ZA-907563-B (ZA)
Title: Device for the measured dispensing of liquids out of a storage container
Inventor: RAAB ALFRED
IPC: B67D1/00
Filed: 1990-09-21
Abstract: A dosing system has a vessel for holding a fluid and a dosing device for dispensing a measured quantity of fluid from the vessel. The dosing device hermetically seals the vessel and has a valve with a fluid passage, a piston surrounding the valve and a cylinder housing surrounding the piston. The valve is positioned in a first position wherein fluid is gravity fed from the vessel to a chamber formed between a drive face of the piston and the cylinder housing. The valve can be reciprocated from the first position to a second position whereat the valve closes the inlet from the vessel to the chamber. The piston closes the passage within the valve when the valve is in the first position and opens the passage when the valve is moved to the second position to permit discharge of fluid from the chamber. When the valve moves to a third position, the drive face of the piston moves toward a shoulder of the cylinder housing to thereby pump the fluid from the chamber. The valve can be moved between these three positions to repeatedly discharge fluid. When the valve returns from the third through the second to the first position, the drive face of the piston will move away from the shoulder of the cylinder creating suction in the chamber. This suction will assist in the gravity feed of fluid from the vessel to the chamber. The dosing system is particularly useful in a dispenser for a beverage and the vessel can be a bag-in-box container. A pliable funnel portion is provided between the vessel and the dosing device whereby the dosing device may be pushed into or pulled from the vessel.
Patent ZA-913224-B (ZA)
Title: Acoustic transducers
Inventor: TABIN JOZEF
IPC: G10K11/02
Filed: 1991-04-29
Abstract: A broadly tuned transducer system for pulse echo ranging systems has a rigid plate (1), to a planar radiating front surface of which is applied at least one layer of acoustic coupling material (6) having a density intermediate between that of the plate and an atmosphere into which the transducer is to be coupled. Three or more driver assemblies spaced apart in a two dimensional array are rigidly secured to a rear surface of the plate, each assembly having a loading block (3) and a piezoelectric element (2) compressed between the block and the plate (1). The driver assemblies all have the same resonant frequency on axes perpendicular to the plate and are driven in phase; they occupy not less than one fifth and not more than four fifths of the area of the rear surface of the plate, which is rigid enough to prevent the excitement of significant flexural oscillations. The arrangement permits the transducer to have a large planar radiating surface whilst using quite small piezoelectric elements (2).
Patent ZA-916511-B (ZA)
Title: Diamond alpha particle detector
Inventor: JONES BARBARA LYNN
IPC: G01T1/26
Filed: 1991-08-16
Abstract: A radiation detector element which is optimised for the detection of alpha particles comprises a layer (10) of diamond or diamond-like carbon with first and second electrical contacts (14, 16; 18) applied to the surface of the layer. The layer is formed on a silicon substrate (12), together with an electronic circuit (T1, T2, T3). Each of the contacts (14, 16; 18) defines a rectifying junction with the layer (10), thus defining a back-to-back diodic structure, having junction characteristics which are responsive to the intensity of radiation incident on the detector element. The electronic circuit is powered by a battery (24) or a solar cell (28), and activates an LCD indicator (26) if the intensity of the incident radiation exceeds a predetermined level. The radiation detector element and the electronic circuit are housed on a card (22) which is sized similarly to a conventional identification card. <IMAGE>

Title: Internetworking system and method
Inventor: TAKASHASHI SOICHI
IPC: H04L69/14
Filed: 2000-04-06
Granted: 2004-03-03
Abstract: An internetworking system and method enabling efficient communication between networks that use different protocols. A network management station comprises a first connection setting unit, a downstream frame generator, and a frame communication unit. The first connection setting unit establishes a first connection over a network A to reach a gateway network element. The downstream frame generator produces a downstream frame containing identifiers of remote network elements. The frame communication unit sends out the downstream frame through the established first connection, and/or processes an upstream frame received through the same. The gateway network element serves as a mediation device, comprising a second connection setting unit and a frame mediation unit. The second connection setting unit establishes a second connection reaching the network elements, over networks B and C whose protocols are different from that of the network A. The frame mediation unit mediates the transport of downstream frames toward the network elements through the second connection. It also mediates the transmission of upstream frames toward the network management station.

Title: Construction of dna sequences and their use for microbial production of proteins, in particular human serum albumin
Inventor: LAWN RICHARD M
IPC: C12N15/00
Filed: 1982-08-25
Granted: 1985-12-24
Abstract: By means of reverse transcription of mRNA coding for a desired polypeptide, there is obtained a set of overlapping fragments of duplex cDNA, which together correspond to the whole mRNA molecule. The fragments have overlapping regions bearing sites for restriction enzymes, such that cutting and ligation gives DNA corresponding to the polypeptide. This is introduced into a vector in reading frame with a promoter. Transformation of a microorganism enables expression of the polypeptide. The construction via fragments enables large molecules to be made. Thus, human serum albumin (HSA) is produced by E. coil transformed with plasmid pHSAI. This includes DNA made from fragments derived from reverse transcription of mRNA from human liver.

Title: Chemiluminescent esters thioesters and amides and their use in assays
Inventor: MCCAPRA FRANK
IPC: C07D221/06

Granted: 1992-10-14
Abstract: In accordance with the present invention, specific binding assays are disclosed which utilize an chemiluminescent compound, i.e., moiety, which has increased stability in aqueous solution. The chemiluminescent moiety is an ester, thioester or amide in which the ester, thioester or amide linkage is between (1) a heterocyclic ring or ring system containing a carbon atom to which the linkage is attached, wherein the heteroatom within the heterocyclic ring or ring system is in an oxidation state which renders such carbon atom susceptible to attack by peroxide or molecular oxygen to form an intermediate which decays to produce chemiluminescence, and (2) an aryl ring or ring system. The aryl ring or ring system contains at least one substituted six-member ring. The substituted six-member ring has two or more substituent groups, where at least two of said two or more substituent groups sterically hinder hydrolysis of said linkage. One or more of the substituent groups which sterically hinder hydrolysis of said linkage may be an electron withdrawing group. The substituted six-member ring may have one or more additional substituent groups in addition to the substituent groups which sterically hinder hydrolysis of the linkage. Such additional substituent groups may also be an electron withdrawing group. The carbon atom in the heterocyclic ring or ring system, to which the linkage is attached, may also have a secondary substituent of the formula RnX-, where X is selected from the group consisting of O, N, S and C, where R is any group, and where n is a number such that X has proper valency.
