Inventor: GROT WALTHER GUSTAV
IPC: C25B13/08
Filed: 1982-10-22
Abstract: A process for preparing a fluorinated polymer having carboxylic ester groups from a corresponding polymer having carboxylic acid groups is disclosed, wherein the polymer having carboxylic acid groups is treated with a selected ortho ester, acetal, ketal, borate ester or sulfite ester. The process is useful for assuring that all of the carboxylate groups of a polymer are in the ester form before an extrusion or lamination procedure, both of which are performed with heat and pressure, so as to preclude decarboxylation of free carboxylic acid groups during such procedure.

Title: Improved apparatus for transferring printed material onto a chain delivery
Inventor: JAMIESON H WILLIAM JR
IPC: B65H29/04
Filed: 1983-09-29
Abstract: improved apparatus for facilitating the transfer of a printed sheet, without smudging or wrinkling, to a chain delivery mechanism of the type commonly used in an offset printing system. The apparatus is of the type that includes a bar having a pair of clips at its opposed ends for engaging the continuous chains of the chain delivery. The bar includes at least one paper contacting member that is both rotationally and longitudinally adjustable thereon. The clips, which releasably secure the bar to the continuous chains, are arranged to apply compressive retaining forces to the (inner) vertical side members pre-selected links of the continuous chains so that the mobility of the links of the chains is substantially unaffected by the presence of the clips.

Abstract: A variable format CRT display is driven by a transistor 10 which is turned-off by a synchronising pulse 20 and is turned on when the coil current generated by a diode and capacitor circuit 44 reaches a settable threshold 54. Drift compensation is exercised by a delay mechanism fixed by the synchronising pulse, which sets a latch 22, quenching transistor 25 and allowing capacitor 26 to charge through a variable resistance 46. When the ramp voltage 24 attains the voltage of a second capacitor 27, comparator 18 generates a pulse 30 setting latch 12 and turning off transistor 10. The flyback current 43a is clipped to a pulse 43b which fires transistor 40 to enable a current minor 34, 45 to charge capacitor 27 until the ramp voltage reaches a reference value 29 whereat capacitor 27 discharges and capacitor 26 is discharged. If discharge is not centred on pulse 43b, the charged state of capacitor 27 will vary to tend to maintain centring. Variables 32, 36 and 54 exercise gross control.

Abstract: A paper making machine includes a dryer section which constitutes 50% or more of the length of the paper machine. It has been proposed to reduce or obviate this dryer section by subjecting the paper sheet simultaneously to high nip pressures and temperatures, but conventional wet press felts are not suitable in a press drying system. 
     The invention is concerned with an endless foraminous belt for releasing moisture from fibrous paper making dispersions or sheets formed therefrom which comprises a flexible corrosion and stretch resistant sheet having a high tensile sheet and formed from fine woven metallic mesh in which the warp and weft filaments are bonded together at their points of intersection, as by sintering. The belts can be used in press drying or in other parts of the paper machine.

Abstract: A hydronic heating system circulates hot water from a boiler 11, 13 through a radiator means 20 by a pump 15. An ambient temperature control thermostat 22 feeds control means 25 which controls the fuel valve 30. A sensor 35 senses the water temperature in the boiler heat exchanger 13, and the control means 25 hold the pump off until the water temperature reaches a predetermined value, thereby avoiding condensation and rust in the boiler. In this invention, for improved operation the control means monitors the rate of change of water temperature when the burner 11 is turned on, thus checking that the sensor is working. The system may also be shut down if the rate of change of temperature is too low (not heating properly), or too high (water level 43 too low).

Abstract: Um eine umgebungsunabhängige Kontaktgabe zu erreichen, sind zwei hermetisch verschlossene Kontaktpillen (31, 32) vorhanden. Jede Kontaktpille weist einen Umschaltekontakt auf und besitzt als bewegliches Glied eine Membran (1, 1') aus elektrisch und magnetisch leitendem Material, welche Membran infolge des durch einen Permanentmagneten (35) bewirkten und durch den Kern (37) einer Steuerspule (36) fliessenden Magnetflusses an entsprechenden Kontaktpolen (5, 6' oder 6, 5,) haftet. Für die Umsteuerung des Relais genügt ein Stromimpuls durch die Steuerspule, welcher einen Steuerfluss bewirken muss, der nur wenig grösser ist als der Permanentmagnetfluss, weil sich die beiden Flüsse nach eingeleiteter Umteuerung in ihren Wirkungen unterstützen. Dank dieser Unterstützung ist die benötigte Steuerleistung so gering, dass eine direkte Ansteuerung durch TTL-Schaltungen möglich ist. Durch andere Anordnung des Permanentmagneten im Magnetkreis sind auch monstabile Relais realisierbar.

Abstract: In order to pest control tobacco there is provided in a gas tight tobacco storage room an inert O2 lacking atmosphere with O 2  between 0 and 5%, CO 2  between 1 and 20% and the balance N 2 . This atmosphere is maintained until mortality of the pest. The system for providing this atmosphere includes essentially a generator, which can be a combustion chamber (1) associated to a catalytic chamber (2) (in the case of an open circuit system in which air is drawn from the atmosphere) or a catalytic chamber alone (in the case of a closed circuit system in which air is drawn from the tobacco storage room itself) and a cooling tower (3). 
     The system is generally provided also with an evaporator (5) and a condenser (6) to control the humidity of the inert atmosphere, and a heat exchanger (7) in which the combustion heat is utilized to heat the inert atmosphere at a temperature which speeds up the mortality of the pest.

IPC: H01J49/42
Filed: 1984-02-22
Abstract: This invention relates to a method of operating quadrupole mass spectrometers with only an RF potential applied to the filter rods so that the spectrometer operates to pass all ions above a particular value of m/e. In practice, spectrometers operated in this way usually show a marked loss in transmission efficiency for ions of high m/e when operated with an RF potential low enough to pass ions of m/e < 10, and the invention overcomes this defect by providing a method of switching the RF potential between two or more values at which ions of different ranges of m/e values are efficiently transmitted, and combining the output signals at each value to give a resultant signal more accurately proportional to the number of ions formed in the source of the spectrometer, irrespective of their m/e values. The invention can be used to improve the accuracy of total pressure measurement using a conventional residual gas analysing mass spectrometer, eliminating the need for additional pressure gauges.
