Patent CA-2164659-C (CA)
Inventor: MEHNERT WALTER
IPC: G08C19/28
Filed: 1995-12-07
Granted: 2004-06-22
Abstract: In a process for the serial transmission of measurement values which are continuously supplied by a sensor and which occur at the transmitter end in digital form, to a receiver, the measurement values are ascertained at such short time intervals that their deviation from the respectively precedingly ascertained measurement value can be represented generally by only two bits of which the one reproduces the sign and the other the value of the deviation. Of the measurement values which occur within a predeterminable period of time, only a respective one is completely transmitted as an absolute value while of the others only the respective incremental alteration values which are related to the one measurement value are transmitted. At the receiver end 'virtual' measurement values corresponding to the measurement values occurring at the transmitter end are synthesised by the transmitted incremental values being added, correctly in respect of value and sign, to the completely transmitted absolute value.
Patent CA-2166397-C (CA)

IPC: G06F17/50
Filed: 1994-06-29
Granted: 2000-03-21
Abstract: A method of and apparatus are disclosed for evolving successive populations of molecular structures and evaluating each evolved structure of each population with desired physical and/or theoretical properties. An initial population of molecules is provided (12, 14) in terms of representations of a number of member molecules. Evaluation is performed by a fitness function (16, 18), which compares the initial population and evolved generations of member representations with the set of desired properties to provide a numerical measure or value of fitness for each structure (20, 22). That numerical value indicates how closely the compared member representation corresponds with the set of desired properties (24, 26). The next population is generated by changing the structure of selected molecules of a population dependent upon the numerical measure of fitness (28), and the process repeats (30, 14). Subsequent populations evolve towards even better fitness. The process is terminated when an acceptable molecule evolves.

Abstract: A granulator for granulating molten material comprises a rotary atomiser to which the molten material is supplied. Without the assistance of fluid jets, the molten material is broken up into globules which are caused to pass through an air curtain containing entrained granules. This has the effect of accelerating the cooling rate of the globules to form granules and also of reducing the kinetic energy of the granules so that the length of their flight path is reduced thereby allowing the overall size of the granulator enclosure to be reduced.

The bottom ends of the grid walls form a base which is large compared to the height of the walls. Each grid (10) stands on the cell bottom in stable manner durinthe operation of the cell and is easily removable from the cell and insertable in the cell. Each grid (10) has generally vertical through-openings (13) dimensioned to allow the molten cell content to occupy the inside of the through-openings. These vertical through-openings (13) are in communication with the molten aluminium in the pool or layer (32) so that the molten aluminium occupies at least a part of the height of the openings (13). These grids reduce movements in the aluminium pool and their top parts may act as a drained cathode.

Abstract: An asymmetrical data communications system (ADCS) provides point-to-multipoint television programming including conventional television programming, near video-on-demand (NVoD) or video-on-demand (VoD), and the full variety of available programming, via a compressed, digitized UHF transmission. A program subsystem of the ADCS receives programming from content providers and processes the received signals for channel and VoD or NVoD service, then sends the aggregated signal to a transmission subsystem that modulates, channelizes, amplifies, filters and broadcasts the digital UHF signals over the air. Subscribing viewers are equipped with an intelligent control box (ICB) suitably configured to receive, demodulate, and decode the digital UHF broadcast and to transmit the resulting signal to one or more display or other terminal devices. The ICB further provides a matrix switch or gateway for receiving signals over any available transmission path. In addition to the ICBs of the subscribing viewers, a return path subsystem of the ADCS system includes a session control and administrative facility to which the ICBs are linked via the public switched telephone network or suitable wireless alternative so that transaction and viewing data can be received from the subscribing viewers. The return path subsystem, in turn, is linked to the program subsystem in order to route to that subsystem any information necessary or useful for providing programming.

Abstract: Lampe fluorescente à électrode externe et unité d'éclairage utilisant ladite lampe fluorescente. La lampe fluorescente (10) comprend un tube de verre (1) dont la surface interne est revêtue d'un matériau fluorescent (3) et qui contient une quantité prédéterminée de gaz rare, une paire d'électrodes (2, 2') disposées à la surface externe du tube de verre (1) en direction axiale, et un élément réfléchissant disposé sur le côté opposé à l'ouverture (4) au travers de laquelle la lumière est émise. Une partie de l'électrode (2, 2') est transparente. Un élément réfléchissant (6') est disposé sur la partie transparente. Quand une partie de l'électrode (2, 2') comporte une partie transparente, la capacité de la lampe ne diminue pas notablement et l'énergie qui lui est fournie est proche de celle fournie à la structure sans partie transparente. L'émission de lumière augmente donc d'une quantité correspondant à l'influence de l'élément réfléchissant (6'). La partie transparente peut avoir n'importe quelle forme, telle que fentes ou orifices multiples. Comme la lampe fluorescente (10) comporte des électrodes externes transparentes, la lumière est émise par l'ouverture (4) et par les parties transparentes (6) formées sur les électrodes externes (2, 2'). La lumière émise par la partie transparente (6) est réfléchie par l'élément réfléchissant (11), puis rayonnée depuis l'ouverture de l'élément réfléchissant en forme de U. La lampe (10) comporte une structure constituée d'une électrode externe partiellement transparente et d'un élément réfléchissant (11) qui réfléchit la lumière traversant la partie transparente (6), puis éclaire la zone d'éclairage, de façon à augmenter la quantité de lumière.
