Title: Recognition of objects particularly biological materials
IPC: G01B11/02
Filed: 1975-02-01
Abstract: 1494357 Image analysis OBJECT RECOGNITION SYSTEMS Inc 1 Feb 1975 4472/75 Heading G1A [Also in Division G4] To compare an object with a reference the object is scanned in two dimensions to form an analogue video signal representing the object; portions of the signal, each corresponding to at least one line of the scan, are averaged and compared with the reference. The averaging can be done by filtering or otherwise; the comparison is made by digitizing the average values and comparing these with the reference. In Fig. 1 a biological specimen 14 is illuminated by a flying spot scanner 11, and a video signal is produced by detector 16. This signal is amplified at 17, and filtered at 18 to remove the line scanning frequency, and higher frequencies. The filtered signal is displayed on CRT 19, which is synchronized with the line scan. The signal amplitude is digitized at 21, but not more often than once per line, so that the amount of digital data to be handled is kept small. The digitized signal is coded and fed to computer 23 where it is compared with stored results obtained when a reference specimen was examined. In a further embodiment, Fig. 2, (not shown), a conventional camera tube may be used to scan the specimen; the computer can receive its inputs from a printer attached to the converter. The signals to be compared with a known reference each correspond to the average of at least one line of the scan. If the CRT trace in Fig. 1 is used, it is an average because of filter 18 and because the lines are superimposed. If an A/D converter is  used, this may be of the kind which digitizes the average value of a signal during the sampling period (here during at least one line), in which case the further averaging of filter 18 is not necessary though preferable. If the A/D converter is of the type which digitizes the value of a signal at the start of the sampling period, the filter is necessary.

IPC: H01B1/00
Filed: 1959-02-11
Abstract: 870,767. Making electric contacts. DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT. Feb. 11, 1959, No. 4817/59. Class 83 (2). In the manufacture of solderable electriccontact elements of silver-cadmium oxide by oxidation of the cadmium in a silver-cadmium alloy, those surfaces of the element which are subsequently to be soldered are protected against oxidation during the oxidation treatment. A moulded element of silver-cadmium is partially enclosed in a crucible of refractory material and is oxidized by calcining in air at 700-850 C. The surface of the element which projects into the crucible is protected from oxidation; an inert or reducing gas may be introduced into the crucible. Alternatively, the solderable surface of the element may be protected by a gas-tight layer of a ceramic material such as aluminium oxide applied by a flame-spraying process. In another embodiment two sheet-like elements of silver-cadmium alloy are superposed with their solderable surfaces in contact. These surfaces are sealed around the edges, for example, by welding, and the elements are then calcined in oxygen for 70 hours at 800 C. The two sheets are then separated.

Abstract: 465,380. Oil-break switches; contacts. WHITEHEAD, G. E., and WHITEHEAD'S ELECTRICAL INVENTIONS, Ltd. Feb. 19, 1936, No. 5089. [Class 38 (v)] A switch or circuitbreaker has its " fixed " contact located in a perforation in a partition or barrier across the oil tank but leaving one or more channels which is or are adapted to be nearly closed by a valve except when the switch or breaker contacts are closed. As applied to the circuit-breaker described in Specification 464,643, in which the "fixed" contact 3 is urged towards the movable contact 2 by a spring 8 and is in sliding engagement with a resilient sleeve contact 6, for example of the character described in Specification 409,085, in a tubular extension 7 of the terminal stem 4, the valve is in the form of a flanged member 15 carried by the pin 10 which engages slots 9 in the extension 7 to limit the travel of contact 3. The flange is provided with recesses 16 which are staggered with respect to longitudinal pressure-relieving grooves 14 formed in the tube 7. There is a slight clearance between 7 and the insulating shrouding tube 11 which is housed in perforations in cross-barriers 12, 13 in the switch-tank. When open, the valve allows free access between both sides of the partitions, and when the breaker opens, the valve causes the oil under the partitions to be placed under pressure, the oil only slowly escaping through the perforations. With excessive pressure the valve is lifted, but in any case the oil flows back through the tube when normal conditions are restored. Perforations may replace the recesses 14, 16.
