Patent CA-2186613-A1 (CA)
Inventor: GIGL JOHN J
IPC: B29C67/00
Filed: 1995-04-25
Abstract: A method and apparatus for making high resolution objects by stereolithography utilizing low resolution materials which are limited by their inability to form unsupported structures of desired thinness and/or their inability to form coatings of desired thinness. Data manipulation techniques, based on layer comparisons, are used to control exposure in order to delay solidification of the material on at least portions of at least some cross-sections until higher layers of material are deposited so as to allow down-facing features of the object to be located at a depth in the building material which is equal to or exceeds a minimum cure depth that can effectively be used for solidifying these features. Similar data manipulations are used to ensure minimum reliable coating thicknesses exist, above previously solidified material, before attempting solidification of a next layer. In addition, horizontal comparison techniques are used to provide enhanced cross-sectional data for use in forming the object. Further, several techniques for automatically performing Z-error correction through the manipulation of a three-dimensional object representation are described. Still further, techniques for producing objects useful for investment casting applications are described, including techniques allowing for the drainage of unsolidified material. A method and apparatus for the automatic generation of vents and drain is also provided.

Title: Separating and concentrating certain ions using ion-binding ligands bonded to membranes
Inventor: DI LEO ANTHONY J
IPC: B01J20/32
Filed: 1995-04-25
Abstract: A method for removing, separating and concentrating certain selected ions from a source solution that may contain larger concentrations of other ions comprises bringing the source solution in contact with a composition comprising an ion-binding ligand covalently bonded to a membrane having hydrophilic surface properties. The ligand portion of the composition has affinity for and forms a complex with the selected ions, thereby removing them from the source solution. The selected ions are then removed from the composition through contact with a much smaller volume of a receiving solution in which the selected ions are either soluble or which has greater affinity for the selected ions than does the ligand portion of the composition, thereby quantitatively stripping the complexed ions from the ligand and recovering them in concentrated form in the receiving solution. The concentrated ions thus removed may be further separated and recovered by known methods. The process is useful in the removal of selected ions, including noble metals and other transition metals from a variety of source solutions-such as are encountered in semicondutor, nuclear waste cleanup, metals refining, environmental cleanup, providing ultra high purity fluids, electric power, and other industrial enterprises.  The invention is also drawn to the ligand-membrane compositions.

Title: Recipient en plastique recycle
Inventor: FEHN GREGORY M
IPC: B32B27/32
Filed: 1995-08-01
Abstract: Récipient constitué de plastique recyclé après utilisation ("PCR") et procédé d'utilisation de ce type de récipient. Ce dernier présente à l'intérieur une couche de polypropylène ou EVOH ou une pellicule de polyéthylène fluoré empêchant les substances contaminantes contenues dans le plastique recyclé de se mélanger au contenu du récipient. Lorsqu'on utilise l'EVOH, le récipient comporte généralement une couche supplémentaire de polyéthylène ou polypropylène recouvrant l'EVOH afin d'éviter que ce composé ne se détériore sous l'effet de l'humidité. Afin de produire ce récipient, on compose d'abord une résine comprenant le plastique recyclé. L'adjonction des différentes couches susmentionnées permet de réaliser un récipient composé de plastique recyclé et comportant une barrière qui limite la migration de substances contaminantes depuis les matières recyclées vers le contenu du récipient. On peut ainsi utiliser ces récipients pour les denrées alimentaires. Lorsqu'on utilise une pellicule de polyéthylène fluoré, la fluoruration peut se produire avant ou après la formation du récipient.

Title: Road surface repair attachment for dump-truck
IPC: E01C19/48
Filed: 1997-09-10
Abstract: A box of the attachment apparatus receives asphalt from the discharge chute of a forward-tip dump-truck. The asphalt is deposited on the rod in a stripe, and is compacted by being rolled over by the rear wheel of the truck. The thickness of the stripe is set by side-runners, which hold the bottom of the box clear of the road. The weight of the asphalt-laden box loads the side-runners against the road, and permits pre-compaction, in which the stripe of asphalt is partly pre-compacted before being rolled over by the wheel. Where the truck has double rear wheels, the stripe can be as wide as the width of both wheels. The box is carried on a parallelogram linkage, which is mounted from the chassis of the truck.

Title: Optical record carrier and method for recording and reproducing signals therefrom
Inventor: TANAKA SHIN-ICHI
IPC: G11B20/10
Filed: 1996-04-01
Abstract: An optical record carrier (RC and RC'), and methods and apparatuses for recording and reproducing an information on and from said optical recording carrier (RC and RC'), whereby the effects of crosstalk from adjacent tracks (TR) is reduced, and stable tracing control is possible, is achieved. A  recording track (TR) to which information (Sm) divided into sector units (S) is recorded is formed in a spiral or concentric pattern on the surface of the optical record carrier (RC and RC'). Each sector further comprises sixty frames (FRf). Each frame (FR) comprises a re-sync pattern (RS), frame address (FA), data (INF), and postamble (PA) fields. Identification information (SA) indentifying the sector location of the information (INF) is recorded to the data block of the first frame (FR1). The user data (UDf) is recorded after the data (INF) is scrambled using a value (SR) generated by a fifteen-stage maximum-length sequence generator (603) based on the value of this identification information (SA). The correlation between signals on adjacent tracks (TR) is thus reduced, and the effects of crosstalk are randomized, thus reducing the effect on the track error signal and enabling extremely stable tracking control.
