Title: System for generating line drawing of a scanned picture
IPC: G06T5/00
Filed: 1978-07-05
Abstract: A digital system detects edges in a full tone picture by scanning and reproduces them in solid lines of controllable width to provide an outline drawing of the picture. Each line of video information produced by scanning the picture is digitised by an A-D converter. Each digital sample is compared to a digital sample delayed by a predetermined amount to generate a difference signal which is indicative of a change in the gray scale in a direction perpendicular to the scanned lines. The digitised samples of the video signal are stored in shift registers having capacity sufficient to store data representing a plurality of scan lines. Selected digital samples from the stored data are compared to samples of the line being scanned to detect changes in the gray scale in a direction parallel to the scanned lines. These detected changes in the gray scale are combined to generate a signal which operates a printer to generate a line drawing of the scanned picture.

Title: Extraction process using stabilized emulsions.
IPC: B01D11/04
Filed: 1979-10-03
Abstract: An extraction process for transferring at least one species between a fluid phase and a first liquid phase contacting the fluid phase with an emulsion of the first liquid phase in a second liquid phase that constitutes a liquid membrane permeable with respect to the species to be transferred is characterised by the feature that the emulsion is stabilized by the presence therein of at least one particulate solid which is substantially insoluble in and non-reactve to constituents of and contained in each of the phases. Preferred solids are fumed silica and carbon black. In one embodiment, the phase into which the species is to be transferred is kept lean with respect to the species to be transferred. In another embodiment, mass action is utilized to maintain a driving force by counter-transport of a different species. Where all phases are liquid, one phase is regarded as the bulk phase and the first liquid phase termed the internal phase is contained in a surrounding membrane of the solids-containing second liquid phase, called the external phase. Transfer may be from the bulk to the first liquid phase or vice versa. The bulk and internal phases are normally aqueous in nature.

Title: Method and apparatus for generating complex characters.
IPC: G06K15/10
Filed: 1980-12-16
Abstract: A character compaction and generation method and apparatus which is particularly adapted to the generation of complex characters such as Kanji characters. A dot matrix defining a given character is compacted into a sparse matrix, with the original character being reconstructed for printing or display from the compacted character defined in the sparse matrix. Each character in the complex character set is compacted and stored in memory one time only, with decompaction being performed each time a given character is to be generated. A set of symbols are defined to represent different patterns which occur frequently in the entire complex character set. Different combinations of the symbols define a given character. The information stored for each sparse matrix representing a given character is comprised of each symbol in the sparse matrix, its position, and its size parameter if the symbol represents a family of patterns which differ only in size. Three groups of different patterns are defined which occur frequently in the complex character set, namely, a first group which has a fixed size for each pattern, a second group which has one size parameter which must be specified for each pattern, and a third group which has a plurality of size parameters which must be specified for each pattern.

Patent ES-8400033-A1 (ES)
Title: Surgical evacuation device.
IPC: A61M1/00
Filed: 1981-09-16
Abstract: A surgical fluid evacuator comprises a flexible, compressible reservoir which draws a substantially constant vacuum to permit uniform removal of fluid from a surgical incision through a wound drain catheter. The reservoir comprises a pair of congruent, articulated plates (10a, 10b) having the area between them sealed from the atmosphere by a flexible membrane 40. A spring (14) between the plates (10a, 10b) biases them apart to create a vacuum in the reservoir. As the reservoir, and spring, expands to draw fluid the articulated plates hinge to vary the shape of the reservoir to at least partially offset the decreasing force of the spring on the plates.
Patent ES-8303207-A1 (ES)
Title: Tandem brake booster.
IPC: B60T13/563
Filed: 1982-03-09
Abstract: A tandem brake booster (10) having a housing (12) with a cavity therein divided by a first wall (24) and a second wall (28) into first, second and third chambers (20, 26 and 30). The first and second chambers (20, 26) are connected to each other through a control valve (62) and the first and third chambers (20, 30) are connected to each other by a conduit (38). The second wall (28) is connected to the first wall through lever arrangements (100 and 102). When the first chamber (20) is connected to a source of vacuum, air is evacuated from the first, second and third chambers (20, 26 and 30). In response to an input force, the control valve (62) interrupts communication of vacuum to the second chamber (26) and allows air to be communicated to the second chamber (26). With air in chamber (26) and vacuum in the first and third chambers (20 and 30 ) a pressure differential is created across walls (24 and 28). This pressure differential simultaneously acts on the first wall (24) and second wall (28) by moving the first and second walls (24 and 28) in opposite directions to develop first and second output forces. The second output force is transmitted through the lever arrangement and added to the first output force to produce an operational force for activating a master cylinder.

Title: Oil detection device for e.g. marine bilge monitoring
IPC: G01N21/17
Filed: 1983-03-02
Abstract: The scatter cell of the detector arrangement comprises a housing through which water carrying suspended oil may flow, and is provided with an inlet window for incident light and outlet windows (13,14) for receiving light scattered from the suspended oil. Typically the incident light beam is provided via an infra-red solid state laser but another light souce may also be used. A baffle may be mounted adjacent the window to ensure that only scattered light reaches the outlet windows. Scattered light reaching the windows is fed to respective photodetectors, pref. via optical fibres. Advantageously the scatter cell also includes a further output window whereby the intensity of the incident beam may be monitored thus providing for computation for compensation of changes in that intensity. The outputs of the photodetectors are coupled to electronic circuitry, e,g, a microprocessor, programmed to compute an oil concentration level from the absolute and relative values of the photodetector outputs.
