Patent CA-2038583-A1 (CA)
Inventor: MAEDA SHIGEMI
IPC: G11B27/10
Filed: 1991-03-19
Abstract: An information recording and reproducing device uses a recording medium which is provided with units composed of blocks and a unit information recording area. The recording area contains unit allocation information, sector number information indicating the number of sectors per unit, and unit number information identifying each unit. When the recording medium is placed in the device, the respective information is read by a calculating unit and is used forcalculating physical sector numbers corresponding to a block specified in recording and reproduction operations. Access operations are performed to the calculated sectors, which allows the desired information to be recorded. The block includesdummy sectors which are added before and after each group of a predetermined number of effective sectors. When high-volume information is recorded over several blocks, the dummy sectors may be provided only for the first and last blocks. The device records a group of information whose volume varies from the smallest block number toward the larger block numbers, while it records a group of information whose volume is fixed from the largest block number. Thus, the recording area iseffectively used. The device easily conducts the information management when a host device specifies a block. The file management may be executed by providing a unit for recording file management information separately from a unit for recording files.

Filed: 1991-07-12
Abstract: ABSTRACT           A method and apparatus for flipping and folding a pliable workpiece, such as a pre-hemmed sleeve blank, along a desired fold axis.  A workpiece is conveyed past a flipping roller and down against a clamp bar wherein it is clamped at a predetermined time by a lower hem guide.  The flipping roller is sped to impart linear momentum to the unclamped, trailing portion of the workpiece.  The flipping action serves to re-orient the workpiece from a right side-up orientation to an inside-out orientation so as to properly present the workpiece for subsequent seaming or stitching operations.  A sensor is provided to determine the length of the workpiece so as to enable the device to clamp the workpiece about any desired fold axis.

Patent CA-2070835-A1 (CA)
Inventor: HERKENBERG WOLF
IPC: B01D17/02
Filed: 1990-12-05
Abstract: Des substrats oléophiles hydrophobes en feuilles souples, relativement minces, tels qu'un film de polyéthylène, sont utilisés comme base d'un nouvel agent sorbant en cas de défense contre des nappes de pétrole. Associant une haute densité de stockage à une forte affinité pour le pétrole, les substrats présentés dans cette invention sont destinés à être déployés sur des zones sensibles au large ou près des côtes en tant que première ligne de défense contre des nappes de pétrole qui s'approchent ou pour une intervention rapide afin de contenir le pétrole à proximité de la source d'écoulement. L'efficacité et l'économie pour des applications spécifiques sont obtenues en se basant sur le principe selon lequel l'absorption du pétrole par masse unitaire de substrats sous forme de film augmente si l'on réduit l'épaisseur du substrat. Selon cette invention, le dispositif sorbant spécifique comprend deux films souples (28a, 28b) placés en couches et scellés, qui présentent au niveau de l'un des deux films au moins une pluralité de bulles aplatissables (29) comportant de petites ouvertures (25a, 25b) situées à l'opposé les unes des autres de manière à ce que les bulles aplaties cèdent du volume et se dilatent lorsque le pétrole y pénètre, formant ainsi des poches (23) capables de contenir un volume considérable de pétrole. On peut avantageusement incorporer des additifs décomposant le pétrole au film à partir duquel, selon cette invention, sont fabriqués les dispositifs sorbants.

Title: Apparatus and method for transient thermal infrared spectrometry of flowable enclosed materials
Inventor: MCLELLAND JOHN F
IPC: G01J5/60
Filed: 1992-08-11
Abstract: ABSTRACT OF THE DISCLOSURE  A method and apparatus for enabling analysis of a flowable material enclosed in a transport system having an infrared transparent wall portion. A temperature differential is transiently generated between a thin surface layer portion of the material and a lower or deeper portion of the material sufficient to alter the thermal infrared emission spectrum of the material from the black-body thermal infrared emission spectrum of the material, and the altered thermal infrared emission spectrum is detected through the infrared transparent portion of the transport system while the altered thermal infrared emission spectrum is sufficiently free of self-absorption by the material of emitted infrared radiation.          The detection is effected prior to the temperature differential propagating into the lower or deeper portion of the material to an extent such that the altered thermal infrared emission spectrum is no longer sufficiently free of self-absorption by the material of emitted infrared radiation.  By such detection, the detected altered thermal infrared emission spectrum is indicative of characteristics relating to molecular composition of the material.

IPC: B25B7/00
Filed: 1992-09-30
Abstract: ABSTRACT OF THE INVENTION           A crimping tool comprises a pair of handles, crimping jaws, dies, and/or die nests, positioned at one end of the handles and in alignment with each other to receive a connector therebetween, a linkage extending between the handles and joining same together such that one handle pivots relative to the other and forces the jaws, dies, and/or die nests toward each other. A spring is positioned between the handles to facilitate the opening movement of the tool.   The spring in the present invention is configured with a fracture zone, and is positioned in such a location that the spring is flexed during each cycle of operation.  The fracture zone may include one or more coils, and such coils break, after a predetermined number of cycles, to affirmatively indicate to the user that the tool requires inspection and/or servicing.  When the spring breaks, the tool may still be manually opened, but only with some difficulty, so that the operator cannot ignore the need for inspection and/or servicing.
