Granted: 1998-12-15
Abstract: In a convergence error detecting apparatus for use in combination with a display system of a projection type which displays, onto a display panel, a projected image signal which has a first synchronization signal of a predetermined frequency, and for detecting a convergence error signal representative of a convergence error appearing on the projected image signal, image pickup device is operated by a second synchronization signal of a frequency different from the predetermined frequency, for picking up the projected image signal to produce a pickup image signal by the use of the second synchronization signal, and processing unit processes the pickup image signal to detect the convergence error and to produce a convergence error signal representative of the convergence error.  The convergence error signal is supplied to the display system to remove the convergence error in the display system.

Title: Kit of moulded concrete blocks and gravity retaining wall made therefrom
Inventor: HAGENAH GERHARD
IPC: E04B2/08
Filed: 1992-09-18
Granted: 2003-04-22
Abstract: Known sets of structural elements have blocks with depressions and cross-shaped, T-shaped or Z-shaped connecting pieces which come to be located therein. Only retaining walls which are oriented in a straight line can be constructed.      The set of structural elements according to the invention has, in addition to blocks with depressions, coupling pieces with at least a part thereof being in the form of a truncated cone, with corresponding cross-sec-tional shape of the depression. In this manner, a rota-tion of blocks, in particular located one above the other, is possible. Curved retaining walls can thus be erected.

Title: Video telephone station having variable image clarity
Inventor: KUZMA ANDREW JOHN
IPC: H04N7/50
Filed: 1994-03-23
Granted: 1994-10-02
Abstract: Video telephone apparatus 10 for transmitting video information over a limited bandwidth communications channel includes a source 110 of video frames which arecompressed to reduce the amount of redundant information, and to reduce the level of detail according to a user-selected control signal. The video frames are presented to a compressor 500 at a rate which is varied in order to maintain a constant rate data signal at the compressor's output. As the level of detail is decreased the frame rate is correspondingly increased, thus providing the user with the ability to trade off between image clarity and smoothness of motion. Such tradeoffs are useful when the bandwidth of the communications channel is severely constrained. The control signal is transmitted to the video telephone apparatus 10 from a far-end video telephone over the same channel.
Patent CA-2119794-C (CA)
Title: Method for increasing expansion and improving texture of fiber fortified extruded food products
Inventor: CHIU CHUNG-WAI
IPC: A23L7/10
Filed: 1994-03-24
Granted: 1997-10-14
Abstract: A method is provided to increase the fiber content of extruded foods without compromising overall eating quality. It has been recognized that dietary fiber is beneficial in human diet; however, it has been difficult to obtain good or acceptable texture in extruded foods fortified with high fiber because the addition of dietary fiber to these foods adds density. It has now been found that the addition of resistant starch to starting dough mixes for extruded food products not only increases the total dietary fiber of the extruded food product, but also increases expansion and improves the texture of the extruded food over over compositions that do not contain the resistant starch and over compositions that are fortified with other forms of dietary fiber, such as oat bran.

Abstract: A plurality of parallel chain loops have outwardly extending blades and travel in plastic channels over an inclined deck. The chains extend between shafts which rotate in opposite directions and are mounted to the shafts so that alternating chains move up the incline and the others move down. Refuse bags deposited on the deck are torn open by the blades. Small refuse objects fall between the chains and slide down the deck to be discharged, while larger objects are carried by the upwardlymoving chains to the top of the deck. Refuse objects are thereby initially segregated by size.

Abstract: The invention provides an improved ripple pan which compensates for the over-deposition of threshed grain onto the outer portions of the grain pan by channeling the grain to the center of the pan. The pan has a central section with ripples that are perpendicular to the flow of the grain, and two outer sections with outer edges that are elevated above the central section. The ripples on the two outer sections are biased such that the outer edges of the ripples are located rearward of the inner edges of the ripples. An alternate embodiment of this invention solves the problem of excessive grain deposition in the central section of the ripple pan. This embodiment has two outer sections configured similarly to the first embodiment and a central section with a center peak which slopes downward on either side of the peak to the inner edges of the outer sections.

Abstract: An apparatus and related method are disclosed, for receiving, maintaining an d growing biological cells ex vivo within a portable cassette, without exposing the cells to the external environment. The portab le cassette is used in combination with a processor instrument that facilitates an initial inoculation of the cassette with cells of the ki nd to be grown and to distribute those cells in a predeterminded pattern (e.g., uniformly) throughout a cell growth chamber. Thereafter, the portable cassette is used in combination with an incubator instrument that incubates the cell growth chamber so that the cells are optimally expanded. The same processor instrument then is used to harvest the expanded cells from the portable cassette. Both instruments are configur ed to condition the portable cassette during stages of the cell growth process, without disturbing the cassette's sterile system. In additio n, an updatable memory device associated with the cassette stores significant information about the cassette and its condition during the various steps of the cell growth process. Such information is useful both for subsequent archival purposes and for facilitating a resumption of t he cell growth process in the event of any instrument failure or significant alarm condition.

Abstract: Ce procédé de fabrication d'habitations (D) de dimensions standard à l'aide d'une installation de fabrication mobile (100), permet de concevoir complètement la fabrication de maisons de dimensions standard dans un environnement d'usine automatisé. La structure principale de l'installation de fabrication mobile est suffisamment haute pour que l'on puisse y assembler et déplacer des maisons de dimensions standard. Plusieurs chaînes de production (P1-P5) indépendantes permettent de produire chacun des éléments de l'habitation sous la forme de sous-ensembles. On installe les meubles de rangement, les appareils, la toiture, etc. et on effectue les finitions et la peinture dans les maisons partiellement achevées, avant que celles-ci ne quittent l'étage de production. Cette installation de fabrication mobile permet de faire passer, au moyen d'un élément de transport (T), une maison de dimensions standard, en cours de construction, d'une chaîne de montage à la suivante, jusqu'à l'achèvement de la maison. Ensuite, en empruntant une route dont l'accès est régulé, on transporte les maisons achevées sur l'élément correspondant et vers des sites individuels, sur lesquels on a préalablement construit des fondations conçues spécifiquement pour recevoir ces habitations de dimensions standard. On peut déplacer la maison, à partir de l'élément de transport, pour la poser directement sur les fondations. Des moyens de levage (N1-H3) de grande puissance, tels que des ponts de levage à ouverture libre, constituent le matériel clé pour la manipulation et le transport sur les chaînes de montage, à l'intérieur de l'installation de fabrication mobile. Dans la structure principale de cette installation, on peut prévoir une allée traversante carrossable, suffisamment large pour que des semi-remorques pourvus de remorques chargées puissent y circuler.
