Abstract: A motor vehicle window (1) intended to be glued to the fixing flange (3) of the window frame of a motor vehicle body is provided along its edge with a profiled bead (4) made from a hardened adhesive material. This profiled bead (4) forms an intermediate element which is no longer plastically deformable between the window (1) and the bead of adhesive (12). The bead (12) has, in cross-section, substantially the shape of a U and has anchoring projections (9, 10). The anchoring projections (9, 10) determine a shape-matching and force-transfer join between the bead of adhesive (12) and the profiled bead (4). They can, furthermore, serve to fix, by clamping, various fishplates, attachments or profiled strips.

Title: Data error correction system
Inventor: HARTNESS CARL B
IPC: G11B20/18
Filed: 1987-09-01
Granted: 1992-06-02
Abstract: ABSTRACT OF THE DISCLOSURE         A data storage system has a plurality of individual data storage units, each of which can undergo unpredictable independent failure.  By dividing data blocks to be stored therein into a number of sub-blocks one or more less than the number of data storage units and creating a redundant data sub-block of the type permitting reconstruction of any one sub-block of data using the remaining sub blocks and the redundant sub-blocks, and then storing each of the data sub-blocks and the redundant sub-block on a different one of the data storage units, it is possible to reconstruct any one failed data sub-block of a related group using the other sub-blocks.  It is necessary to be able to detect the failure of the sub-block, and the preferred way is by a multibit error detection code appended to each sub-block, or by failure sensed within and by an individual data storage unit.  The system is preferably implemented with disk drives functioning as the data storage units in view of the well-known tendency of such devices to occasionally generate an error which prevents reading a previously written record on one of them.

Abstract: WIRELINE WELL TEST APPARATUS AND METHOD      ABSTRACT         An improved technique for monitoring subterranean formation test data is provided utilizing an electric wireline to transmit data in real time from sensors positioned downhole in a test string to surface computing and readout equipment The electrical connection between the downhole sensor and the wireline is made by a current coupler technique which reliably allows for transmission of signals representative of downhole test parameters, with the transmitted signals being insensitive to the presence or conductivity of the well fluids. A transmit ter/receiver coupler half is carried in the well via conductor wireline on a latch tool for coupled electrical engagement with a mating receiver/transmitter coupler half contained in a down-hole landing recepticle.  The latch tool may be electrically activated to mechanically latch and electronically or mechani cally activated to unlatch from the lanalng recepticle, so that a full bore passage is provided through the landing recepticle when the latch tool is not interconnectcd with the landing recepticle   Two-way data transmission is possible, so that downhole instrumentation and equipment can be activated from the surface via control signals transmitted through the coupler device, and data from downhole sensors can be transmitted in real time to surface computing and recording equipment

Granted: 1993-03-16
Abstract: PHOTORESPONSIVE ARRAY                 ABSTRACT OF THE DISCLOSURE An array for sensing the relative intensity of electromagnetic radiation at a plurality of locations employs a network of photodiodes and non-photoresponsive diodes. A first terminal of each photodiode, e.g. the anode, is electrically connected to a common point which is one terminal of the array. The non-photoresponsive diodes are connected in like-polarity series. The second terminal of each photoresponsive diode is connected to a different connection of non-photoresponsive diodes in the string. The array is scanned with a voltage ramp signal and each change in current flow indicates an illuminated diode. The particular voltage at which current flow changes discloses which photodiode is illuminated. Embodiments of the novel array can be made monolithically without a significant number of conductor cross overs. Monolithic embodiments of the array may be conveniently formed from monocrystalline semiconductors and thin films of amorphous and polycrystalline semiconductors such as amorphous silicon and electrodeposited cadmium telluride-containing semiconductors.

Patent CA-1329100-C (CA)

IPC: A24C5/42
Filed: 1988-05-16
Granted: 1994-05-03
Abstract: ABSTRACT    This invention relates to portable manually operable cigarette making machines, one problem is the number of moving parts any reduction of these parts reduces the cost of the machine and the wearing of these parts.  These machines have two basic functions controlled by a single drive handle, the first controls compaction of tobacco, the second ejection of tobacco.          The compaction function is improved by two alternative cam arrangements interacting with the compactor.  In one embodiment, a stud moving in an internal cam raceway controls all cam motion, this greatly simplifies backward and forward motion of the compactor, preferably the stud is a roller stud.  In the other embodiment, an internal cam cooperates with an internal cavity of the compactor.  In both embodiments movement of the handle drive, first moves the compactor forward, then the compactor remains stationary, while further motion of the handle ejects the tobacco.  This not only reduces moving parts hence complexity and wear, but also reduces tobacco dust infiltration, which tends to clog the machinery.

Abstract: The process as defined in my invention for recovering vegetable oleaginous substances from oil-containing natural substances comprises a series of continuous combined pressing and extraction steps to increase and simultaneously to guarantee a high quality product for different kinds of natural substance starting materials.  This is accomplished by subjecting the natural substances, conditioned and comminuted if necessary, after mixing with a solvent phase containing some oil to an intensive processing, mixing and extraction in the shear field of at least one rotor-stator unit and subsequently feeding the resulting liquid phase, through a filter if necessary, to a distillation column.  The solid phase is extracted in successive stages until a residual oil content of 1% is reached and the solvent is fed back to a solid phase in a counterflow.  The process as defined in my invention is universally applicable to all fat and oil-containing natural substances using suitable fluid extraction means.  An apparatus for performing this process is also provided. A variety of rotor-stator assemblies are provided for the rotor-stator unit as defined in the nature of the natural substances being processed.
