Patent ZA-921228-B (ZA)
Title: Apparatus for treatment of living tissues and organes by means of electro magnetic waves
Inventor: BROERS DIETER
IPC: A61N5/02
Filed: 1992-02-20
Abstract: The device has a high-frequency oscillator stage (1) and a low-frequency oscillator stage (2) with a frequency range from 1 Hz to 100 KHz, which are used for generating modulated wave trains and to radiate these wave trains via a transmitting antenna onto the tissue to be treated, or onto a patient. According to the invention, a (partial) frequency run is generated in the frequency range of the low-frequency oscillator stage (2) and during this process a frequency-specific reaction of a patient (8) is detected via a sensor (10) and a signal analyser (11). As soon as a reaction occurs, the frequency run is stopped and the frequency present at the time is retained for a further radiation process. <IMAGE>

Title: Acoustic transducer.
Inventor: CHEREK BOGDAN
IPC: G10K13/00
Filed: 1993-08-09
Abstract: A flexural mode acoustic transducer system for use in pulse-echo ranging systems has a radiating plate (2) of which even-numbered antinodal zones (A2, A4, A6, A8), counting from a drive connection (4) to a driving element (10) at the centre of the plate, are formed with rings of apertures (40) to reduce the radiating areas of those zones, thus reducing cancellation in the far field, and improving the matching of the device to the atmosphere into which the plate is radiating. The plate is backed by a sound deadening layer (32) on a flange (30) of a transducer housing (22), from which it is separated by a foil (34) which is non-adherent to the plate, and is preferably covered by an acoustically transparent fabric having a pore size small enough to exclude damaging particulates. <IMAGE>

Title: Vinyl acetate catalyst preparation method
Inventor: COLLING PHILIP M
IPC: C07C67/055
Filed: 1993-10-14
Abstract: A method of preparing a catalyst particularly useful in the reaction of ethylene, oxygen and acetic acid in the vapor phase to form vinyl acetate comprises impregnating a porous support with water soluble salts of palladium and gold, fixing the palladium and gold on the support as water insoluble compounds by contacting the salt-impregnated support with a reactive solution in two separate fixing stages wherein the treated support is dried and allowed to stand prior to treatment in the second stage to precipitate the insoluble compounds on the support and reducing the insoluble compounds to free palladium and gold. The catalysts prepared in this manner have been shown to provide improvement with respect to reduced selectivity to CO2 during the vinyl acetate forming reaction.

Title: Secure network proxy for connecting entities
Inventor: GREEN MICHAEL W
IPC: H04L29/08
Filed: 1997-09-12
Granted: 2001-03-28
Abstract: A proxy which is part of a firewall program controls exchanges of information between two application entities. The proxy interrogates attempts to establish a communication session by requesting entities with a server entity in lower layers in accordance with defined authentication procedures. The proxy interfaces with networking software to direct a communication stack to monitor connection requests to any address on specific ports. The requestor's address, and the server's address are checked against an access control list. If either address is invalid, the proxy closes the connection. If both are valid, a new connection is setup such that both the requestor and server are transparently connected to the proxy with variable higher levels being connected in a relay mode. Protocol data units are interrogated for conformance to a protocol session, and optionally further decoded to add additional application specific filtering. In one embodiment, an OSI architecture comprises the levels.

Date Aug. 18, 1994Biological activation waste water purification method is disclosed, wherein the waste water is biologically purified in an activation process. Activated sludge is pumped into a circulation circuit comprising a flow channel and at least one distribution channel. Raw waste water is added to the activated sludge to form an activation mixture which is gradually denitrified as it flows through the circulation circuit. The activation mixture is aerated so as to suspend the activated sludge in the mixture while gradually saturating the activation mixture with oxygen so as to change the denitrifying of the mixture to the nitrifying of a mixture as the mixture flows through the circulation circuit. The activation mixture then flows to a fluidized bed filter where it is separated into purified water and activated sludge. The apparatus for biological activation waste water purification comprises a tank with at least one basic module on the bottom of the tank and spaced from the walls of the tank and defining a flow channel about the module. The module has a pair of partition walls which define a pair of separation spaces with the side walls of the basic module and also define a distribution channel which communicates with the flow channel. The partitions also have at least one opening communicating with the separation space and the distribution channel. Aeration members are located in the tank between the basic module and the walls of the tank and between the pair of partitions.
