Patent ZA-837073-B (ZA)
Title: Railway signalling apparatus
Inventor: HEINRICH WALTER
IPC: B61L21/06
Filed: 1983-09-22
Abstract: The invention relates to a device for train location and track-free signalling in the field of an electronic actuator, the actuating groups of which contain microcomputers and are connected to one another via geographic data lines arranged according to the route of the track. Axle counter results acquired at counting points arranged between the actuating elements are passed on along the set routes from actuating group to actuating group. The track-free signalling and the train location occur, using the microcomputer of the actuating groups, by comparing the axle counts registered at the individual counting points. If the distances between the individual counting points are stored, the speed of the vehicles can be determined by means of a real-time determination of the passage of the first axles of the vehicles.

Title: Nonwoven wiper laminate
Inventor: KEBBELL MICHAEL J
IPC: D04H1/56
Filed: 1989-09-26
Abstract: Nonwoven wiper having improved absorbency characteristics and streak-free wiping properties having a laminate construction including a relatively high basis weight middle layer of meltblown thermoplastic microfibers with fibers added and, on one side, a lightweight layer of generally continuous filament thermoplastic fibers having a larger average diameter with a microfiber layer on the other side. These wipers are strong, fabric-like, and are useful for a wide variety of applications including industrial uses, food services, as well as many others.

Title: A polynucleotide tuberculosis vaccine
Inventor: CONTENT JEAN
IPC: C07K14/35
Filed: 1995-11-13
Abstract: Genes encoding Mycobacterium tuberculosis (M.tb) proteins were cloned into eukaryotic expression vectors to express the encoded proteins in mammalian muscle cells in vivo. Animals were immunized by injection of these DNA constructs, termed polynucleotide vaccines or PNV, into their muscles. Immune antisera was produced against M.tb antigens. Specific T-cell responses were detected in spleen cells of vaccinated mice and the profile of cytokine secretion in response to antigen 85 was indicative of a Th1 type of helper T-cell response (i.e., high IL-2 and IFN-gamma). Protective efficacy of an M.tb DNA vaccine was demonstrated in mice after challenge with M.bovis BCG, as measured by a reduction in mycobacterial multiplication in the spleens and lungs of M.tb DNA-vaccinated mice compared to control DNA-vaccinated mice or primary infection in naive mice.

Title: Overload control method for a packet-switched network
Inventor: MA JIAN
IPC: H04L12/801
Filed: 1999-04-27
Granted: 2004-03-31
Abstract: The invention relates to a method for controlling overload in a packet-switched network, especially a mobile or wireless network where the transmission control protocol (TCP) is used as the transport layer protocol. A congestion notification information is added to a data packet following a data packet lost due to a buffer overflow. This is an effective way to improve TCP performance in wireless and mobile networks, since congestion control can be performed completely independent from retransmissions. The proposed mechanism provides a simple way of introducing TCP congestion avoidance control strategies into wireless and mobile networks. In addition, the congestion notification information should be added at least not later than a threshold number of following packets to thereby fasten the rate of congestion control initiation and loss recovery due to congestion.

Title: Processing seismic data
Inventor: ROBERTSSON JOHAN OLOF ANDERS
IPC: G01V1/36
Filed: 2002-05-28
Granted: 2006-07-26
Abstract: A method of determining a vertical component of particle velocity from seismic data acquired using at least one receiver disposed within a water column includes determining the vertical component of particle velocity from the pressure at a first location and a second location. The first location is the location of a first receiver, and is vertically beneath the second location. The method uses an operator accurate for seismic data acquired at a vertical separation between the first and second locations of up to at least 0.4 times the minimum wavelength of seismic energy used to acquire the seismic data. The second location may be at or above the surface of the water column. Alternatively, the method may be applied to a twin streamer seismic surveying arrangement in which the second location is below the surface of the water column and is the location of a second receiver.

Title: Valve element for a steam trap
Inventor: VIVIAN TOM
IPC: F16T1/02
Filed: 2009-10-06
Granted: 2013-12-04
Abstract: There is provided a valve element for a condensate trap comprising an expansion chamber in the form of a metallic bellows having a variable axial length and having first and second ends sealed with first and second end caps respectively. A valve closure member is provided on the second end cap and is arranged to cooperate with a valve seat. A first guide member is coupled to the first end cap and axially extends into the bellows and a second guide member is coupled to the second end cap, axially extends into the bellows and cooperates with the first guide member. This allows relative axial movement between the first and second end caps but restricts relative radial movement between the first and second end caps. This helps to ensure that the valve closure member properly seats on the valve seal.
