Patent ZA-805128-B (ZA)
Title: Device for the pouring of plaster
Inventor: DELCOIGNE A
IPC: B28B1/30
Filed: 1980-08-20
Abstract: The present invention concerns the manufacture of objects made of plaster, essentially in the form of boards and, specifically, the pouring onto a moving conveyor of a mixture of plaster and water into a reservoir with an open bottom installed on top of said conveyor. It proposes to integrate the upstream rear wall of the reservoir within a surface of greater dimensions than the rear wall, and displacing said continuously, with the purpose of presenting a different portion of the surface as the upstream rear wall. The invention allows continuous cleaning of the upstream rear wall without disturbing the pouring process.

Title: Novel prostaglandin analogues and process for making same
Inventor: MIHELICH EDWARD DAVID
IPC: C07D303/14
Filed: 1982-02-19
Abstract: A novel process for the oxidation of olefins to the corresponding alpha-epoxy alcohols which can be incorporated in the total synthesis of members of a novel class of prostaglandin analogues. Olefins are reacted with singlet oxygen in the presence of a group IVB, VB or VIB transition metal catalyst, excluding chromium. The reaction is fast and highly selective to the alpha-epoxy alcohol. When cyclopentene is oxidized in the process of the invention, high yields of cis 2,3-epoxy-cyclopentan-1-ol are obtained. The latter compound is used as a starting material in the synthesis of prostaglandin analogues. The prostanoids of the invention are characterized by an oxa group replacing the methylene group at the 7-position, and the absence of a hydroxyl or other substituent at the 11-position. Members of this class of prostanoids show important cytoprotective properties in animal tests.

Title: Vehicle wheel
Inventor: HUININK HEINRICH
IPC: B60C15/02
Filed: 1984-10-05
Abstract: A vehicle wheel on which can be mounted a pneumatic tire which essentially includes rubber or rubber-like synthetic material, and has a carcass with load-carrying cords which are anchored in the bead regions of the tire via inextensible core rings. The wheel has a rigid rim with laterally outwardly disposed rim flanges; disposed axially inwardly of these rim flanges on the radially outer side of the rim are seating surfaces for the tire. To minimize disrupting effects on the tire tread, while at the same time improving the emergency operating conditions, a support member is disposed axially inwardly of the seating surfaces on the rim. This support member has a diameter which is greater than the diameter formed by the rim flanges. In the region of a given rim flange, the tire wall extends laterally outwardly from a given core ring in a substantially flat manner, and in particular in an angular range of from 0 DEG  to 20 DEG  relative to the axis of rotation of the tire. The carcass neutral line passes through the same region of a given rim flange in such a way as to avoid a turning point. The core rings are eccentrically disposed in their head regions in such a way that when the tire is mounted, the inner diameter of the tire in these bead regions is less than it is during mounting of the tire.

IPC: H04L69/40
Filed: 1997-02-21
Granted: 1998-08-19
Abstract: A transmission monitoring and controlling apparatus is provided between a first system and a second system. The transmission monitoring and controlling apparatus monitors information transmitted through a Fibre Channel. Then, a back controller analyzes the monitored information and stores the information in a controlling memory based on the analysis. For example, when the first system writes data on the second system, the back controller stores the data in the controlling memory. Therefore, even if a failure has occurred in the second system, the transmission monitoring and controlling apparatus is able to read the data from the controlling memory and send the data to the first system instead of to the second system.

Title: Signal correction
Inventor: PARKER JONATHAN
IPC: H03L7/00
Filed: 1999-04-19
Granted: 2003-02-12
Abstract: In a receiver circuit, in which an analog tuner is used to demodulate received signals into in-phase I and quadrature Q signals, typically, the generated I and Q signals are not always reliably separated by exactly 90{ of phase, but any phase imbalance can cause additional noise, due to cross-talk between the I and Q signals. As the phase difference between the received nominal in-phase and quadrature signals is anything other than exactly 90{, there will be a degree of correlation between the received signals. Thus a measure of correlation is calculated in block 22, and the degree of correlation used as a measure of the amount of phase imbalance, allowing an appropriate correction to be applied so that the signals used for further processing are truly orthogonal. The correlation calculation block 22 provides an output to a lookup table 24 in which phase imbalances are stored. The measured phase estimation is then supplied via a loop filter 26 to a correction block 20.
