Title: Temperature control for photometric cells - controls thermoelectric cells from cell and ambient temperatures
IPC: G05D23/24
Filed: 1975-01-09
Abstract: Response time for the adjustment of temperature for spectrophotometric cells is reduced by direct temperature control of the cell. A spectrophotometric temperature control (10) comprises a cell (12) with two light transmission chambers (14) which form receptacles for reference and sample materials. A thermistor (16) is placed in a hole (18) in the cell to be in physical contact with the cell and is placed between two thermoelectric cells (28, 30) with thermal masses (32, 34) permitting stable heating or cooling in response to a signal from an electronic control circuit with two channels. One channel senses temperature changes from the thermistor (16) while a second channel senses ambient temperature changes from a second thermistor (36) placed in the photomultiplier tube compartment.

Title: Protecting schottky power diodes in reverse direction - using double Zener diode, bilateral diode switch, or varistor
IPC: H01L29/47
Filed: 1975-02-18
Abstract: Schottky power diode protected in the reverse direction. The novelty is that it is connected in parallel with a device possessing a first triggering threshold (1) in the forward direction, where (1) is larger than the forward voltage drop at the terminals of the diode, and a second triggering threshold (2) in the reverse direction where (2) has a value lower than the breakdown voltage in the reverse direction of the diode. The triggering device is pref. a wired or integrated double zener diode, a bilateral diode switch or a varistor. The Schottky diode pref. uses a layer of epitaxial Si with a layer of Mo, the Mo being coated with Ni before applying a silver anode. The Schottky diode is protected by a device connected in parallel which does not participate in the conduction in the forward direction but has rapid triggering action to protect the diode in the reverse direction.

Title: Detecting corrosion in buried pipes under cathodic protection - by measuring values and signs of point potentials, maximising certainty
IPC: G01N27/416
Filed: 1976-06-18
Abstract: Method of detecting points of corrosion in a buried metal element; e.g. a pipe, incorporates carrying out, while the pipe is under a cathodic protection potential, an exact measurement of the potential between a point on the ground vertically above a point of electrical leakage, localised by conventional techniques, and a point 2-10 m away, pref. laterally in relation to the axis of the pipe. Those points of escape showing the lowest potential are points of probable corrosion. Those points of leakage are subjected to a further test. The cathodic protection is cut off for a period and a measurement is made to determine the sense of the potential difference between a point on the ground vertically above such a point, and a point remote transversely with respect to the axis of the pipe. The point is considered as a corrosion point with a high degree of certainty if it shows as an anode with respect to the other point. The probable points of corrosion may be determined, if only the potential is measured, and the certain points of corrosion may be determined, if the sign is measured. Prior art methods allow only possible points of corrosion to be determined, in a short space of time.

Title: Cutting system for trimming continuous sheet to length and width - uses lengthwise and transverse cuts forming rectangular openings between sheets to be separated
IPC: B26D11/00
Filed: 1976-07-23
Abstract: The system cuts to length sheetsr or pockets of sheets of paper, aluminum foil, plastic, etc., either rolled on to drums or folded in a zigzag pattern. As the strip is fed forward continuously, a first double lengthwise cut (5, 6) is made near its lengthwise edges (7, 8), its length being a function of the final length of the sheet or packet of sheets. The mid-point of this cut coincides with the centre line (2) separating two sheets or sets of sheets. A transverse cut (9) is then made in front of this centre line by a first cylinder with knife, and then a further transverse cut (12) after the line by a second such cylinder. The part cut out is then sucked up to leave a rectangular opening (15). A further double lengthwise cut (20, 21) is then made, ending at the opening, after which the edge strips (18, 19) thus formed are sucked up and the sheet separated by accelerating its forward speed.

Title: Topographical code for giving map references - uses graduated numbered frame to give code using abscissa and ordinate measurements
IPC: G09B29/10
Filed: 1977-03-11
Abstract: The topographical code enables one to identify a given territory on a geographical map of whatever scale and the exact place and location of a site. A rectangular frame is drawn on the map in which the territory is exactly inscribed. The sides of the frame are subdivided by means of a numbered scale. This scale enables one to reference any position by means of an abscissa and ordinate. For a map of scale 1/1.000.000, the sides of the frame are divided into 999 graduations. The identity of a town and place can thus be identified by a code as well as its name.

Title: System for cleaning heat exchange plates in rotating regenerators - having a mobile trolley and high performance jets
Inventor: FRAUENFELD MARTIN
IPC: F28G1/16
Filed: 1977-04-28
Abstract: The equipment comprises a range of jets for projecting the cleaning fluid towards the plates to be cleaned. The direction of teh jets is virtually parallel to the plane of the heat exchange plates and is mounted in such a way that it may be moved radially relative to the planes of the plates. The jets are fed by cleansing fluid at low or medium pressure which they discharge into ejector tubes situated on the axes of the jets. In the ejector tubes the cleansing fluid is mixed with the ambient heat exchange agent which is sucked into the tubes by the action of the jets. Jets of the mixt. are directed by the ejector tubes between the heat exchange plates. Method prevents the build-up of layers of deposits on the heat transmission plates which can occur with previously known cleaning methods.
