Abstract: ABSTRACT                    Container Closures A container closure,  especially for a drinks can, includes a line of weakness around at least one aperture closed by a displaceable tab.   The line of weakness is sealed by a polymeric material which has been applied as a plastisol and then gelled, the polymeric material being free of polyvinylchloride and the fluid plastisol having a low viscosity in the range 200 to 1800 mPa at 100s-1 and 43°C and below 2000 mPa at 441s-1 and 40°C.  The opening below 2000 mPa at 441s  and 40°C.  The opening force for the tab at the or each aperture is in the range 10 to 60N to allow opening by finger or thumb pressure. The plastisol is for instance based on acrylate ester polymers or styrene/ethylenically unsaturated carboxylic acid copolymers and comprises plasticiser such as dialkyl esters  of  phthalic  or  other dibasic  carboxylic  acid, including  polyester  type materials  and  optionally   a viscosity  depressant  such  as  a  volatile  diluent, a protective colloid and/or an emulsifier, and filler.

Inventor: FORD MICHAEL G
IPC: A61M5/168
Filed: 1991-03-28
Abstract: A system (8) is provided for weighing and monitoring flow from multiple fluid sources (76) into a flow system (10) wherein incoming fluid is received in a weighing bag (80) att-ached to a control system for monitoring the amount of fluid passed through the weighing bag (80) and for preventing admis-sion of air into the flow system (10). An alarm attached to the weighing bag (80) warns when fluid in the weighing bag (80) is approaching empty, so that the fluid in the weighing bag (80) can be replenished from the fluid source (76) before the weigh-ing bag (80) runs dry. If fluid in the weighing bag (80) is not re-plenished, the system automatically shuts down. The fluid pump (72) can be absolutely calibrated using the controlled admission of known amounts of fluids into the weighing bag (80) so that the amount of fluid introduced into the flow system (10) through the weighing bag (80) can be calculated automatically.

Title: Square-root anti-symmetric filters
Inventor: DREWERY JOHN O
IPC: H03H17/02
Filed: 1992-02-13
Abstract: A filter is produced having a real and an imaginary part, such that for positive frequencies the frequency characteristic F of the filter is F = A + jS. The real part A is a skew-symmetric filter and S is a real symmetric filter symmetric about the cut point.  S is related to A by S = $m(r)[A(1-A)]. Once A has been chosen the filter can be derived. A method of forming the filter involves deriving symmetrical and antisymmetrical windows from the filters frequency characteristic A and S and combining the windows to form an asymmetric window.

Title: Speech encoding and decoding capable of improving a speech quality
Inventor: TAGUCHI TETSU
IPC: G10L19/02
Filed: 1992-12-15
Abstract: In an encoding device (103) operable in response to an input speech signal by means of an adaptive transform coding to produce an output encoded speech signal, the input speech signal is partitioned into data blocks by a partition circuit (113).  Each of data blocks is decomposed into a plurality of frequency components by a Fourier transformer (114).  A spectral envelope calculator (120) estimates intensity of a spectral envelope of the input speech signal.  In cooperation with a scalar spectral calculator (115) and a bit assignment determiner (121), a quantizer (116) quantizes or encodes the frequency components with phase information selectively removed from a part of the frequency components on the basis of the intensity of the spectral envelope.  In a decoding device, a phase information assignor assigns pseudo-phase information to each of the frequency components from which the phase information is selectively removed.

Title: Electrokinetic potential measurement
Inventor: PETZOLD JAMES C
IPC: G01N27/07
Filed: 1991-10-04
Abstract: The measurement of electrokinetic potential is of importance in paper-making. A measuring cell (12) for a specific potential known as streaming potential of the kind disclosed in EP B1 0 079 726 is now provided with measuring electrodes (40, 42) of a metal which forms a reversible electrochemical reaction with pure water to oxidise the metal. The electrodes (40, 42) used in the measurement mode in the cell have a film comprising an oxide of the metal electrochemically formed thereover. Such electrodes are found to give more stable and consistent measurement than the stainless steel electrodes used previously. Silver, lead, copper and alloys such as lead and silver are preferred. The measuring electrodes (40, 42) are regenerated within the cell (12) through electrochemical reduction to bare metal, followed by oxidation to re-form the film. This is performed with the aid of auxiliary electrodes (60, 62) in the cell. A control system (50) for the measurement and regeneration mode is described. Excess excursions of the measurement mode voltage are monitored to indicate that the regeneration procedure is to be entered. The measuring electrode (42) in the cell compartment (22) in which the measurement pad is formed is provided with a shroud (13) to protect it during the flushing of the pad from the mesh (14) in the cell.

Patent CA-2099027-A1 (CA)
Inventor: DERBY JEFFREY H
IPC: H04N21/434
Filed: 1993-06-23
Abstract: A packet communications network relies on a few simple parameters to characterize the wide variety of traffic offered to that network, such as peak bit rate, mean bit rate and average packet burst length. A better representation of many types of traffic relies on an equivalent burst length which produces the same loss probability distribution, but assumes that the distribution is uncorrelated and exponential. Access control and bandwidth management based on such an equivalent burst length produces improved decisions due to the more accurate representation of the actual traffic distribution.

Abstract: Abstract of the Disclosure In  a  cross-connect  multiplexer   (CCM2),   a plurality of interface units, among others those (AE1) for STM-1 signals of the synchronous digital hierarchy (SDH),  are  connected  to  a  space-division  switching network (RKF). The section overheads of these synchronous transport modules (STM-1) overall are partly received and analyzed and partly multiplexed and sent out in a section overhead server (SOHS) with the assistance of a network control unit (NCU). This process is simplified by STM-1 signals being converted into a plurality of D39 signals, known per se,  of  a bit rate of  38.912 Mbit/s,  and conversely, only bytes necessary for transmission of the section overheads being inserted into only one of the sixteen frame columns of a D39 signal belonging to the STM-1 signal via the space-division switching network (RKF). It is only these special columns of in each case sixteen STM-1  signals which are  combined to  form a separate D39 signal which is received or transmitted by the section overhead server (SOHS). Such cross-connect multiplexers (CCM2) are used in network nodes of digital networks.            Figure 4

Abstract: Optimized indication signals of a completed data frame transfer are generated by a network adapter which reduces host processor interrupt latency. The network adapter comprises network interface logic for transferring the data frame between the network and a buffer memory and host interface logic for transferring the data frame between the buffer memory and the host system. The network adapter further includes threshold logic where a threshold value in an alterable storage location is compared to a data transfer counter in order to generate an early indication signal. The early indication signal may be used to generate an early interrupt signal to a host processor before a transfer of a data frame is completed. The network adapter also posts status information status registers which may be used by the host processor to tune the timing of the generation of the network adapter interrupt signal.
