Title: Improvements in or relating to method and means for treating polyethylene surfaces to render them adherent to decorative matter
Inventor: TRAVER GEORGE WHITE
IPC: B29C35/08
Filed: 1952-08-07
Abstract: <PICT:0771234/IV(a)/1> The surface of polyethylene sheet is treated to render it adherent to adhesives, pigments, inks, flock and other decorative material by supporting the sheet between an electrode member and a support member of electrically conductive material, providing one of the members with a dielectric cover, spacing the cover from the other member by one-eighth of an inch or less, and applying a voltage to the electrode to cause an electronic discharge across the sheet. As shown, polyethylene film 12 is passed between the upper run 17 of a belt 14 and a series of discharge tubes 21. The belt 14 comprises a fabric base and an upper conducting layer, and is wider than the web.  The tubes 21 each comprise a glass envelope 23, gas-tight and filled with argon or other inert conducting gas, and an electrode at one end.  By means of a series of transformers, one for each tube, an electrostatic field of force is established through the web between the tubes and the belt. The tubes are arranged at a slight angle as viewed in plan to the direction of feed of the web, to ensure equal treatment of all parts of the web, and are spaced from the belt 14 by one-eighth of an inch or less. The run 17 is supported on rollers 18.  In one example, the tubes 21 are 40 inches long, having 37 inches effective length over the film. The belt is operated at 100 feet per minute and the voltage employed is 10,000 or more.  The film is passed twice under the tubes.  In another embodiment, the sheet to be treated is placed between a plate of conducting material and a glass plate, the latter having a sheet of conducting material attached to the surface thereof remote from the conducting plate; the two conducting members are connected to a transformer secondary.  Selected areas of the sheet may be treated, if desired.  Specification 715,914 is referred to.

Abstract: 1304191 Indicating departure of a measured parameter from predetermined limits MONSANTO CO 27 April 1970 [28 April 1969] 20165/70 Heading G4H Apparatus for monitoring values of a parameter, such as the viscosity of rubber, in the form of analogue signals comprises a punched card reactor 6 for reading coded tolerance limits of the signal at predetermined times and generating digital signals representative of the limits and a control signal, a comparator 5 responsive to the control signal and a clock 4 for generating timing signals and sampling the parameter at predetermined times, an analogue to ditial converter 3 controlled by the timing signals, a comparator 8 for comparing the digital output signal from the converter with the tolerance limits and indicating when the signal is outside these limits and a data recorder 12 for recording the tolerance limits and the sampled parameter value in decimal form. Analogue values of the viscosity are measured by a strain gauge and fed via a line 22 to the converter 3. A punched card encoded with binary coded decimal values of tolerance limits of the viscosity and the non-determined times at which the rubber should have a viscosity lying within these limits is inserted in the reader 6 so that when the binary coded decimal time signal from the clock 4 coincides with one of the times encoded on the card, the comparator 5 generates an output signal which is supplied to a circuit 7. The circuit 7 sends a read out signal to the converter 3 so that a sampled digital value of the viscosity is fed both to a comparator 8 and a multiplexer 9, each of which also receive the encoded values of the tolerance limits. The multiplexer, under the control of signals from the clock 4 supplies the parallel coded data representing upper tolerance limit, then the sampled viscosity value followed by the lower tolerance limit to a serializer 10 which provides a decimal output to the recorder 12 such as a typewriter, teletype terminal or paper tape punch. If the sampled value lies outside the tolerance limits a lamp 13 is illuminated by a signal from the comparator 8 and the information is stored in a flip-flop which is interrogated at the end of the predetermined sampling times and is printed out in the form of a query mark. Instead of recording the measured viscosity and the viscosity tolerance limits at pre-determined times, the time the viscosity takes to reach a predetermined value and time tolerance limits may be recorded. The apparatus may also be used in gas chromatography and spectroscopy.

Abstract: 221,222. Luma-Werke Akt.-Ges. Aug. 31, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Switches, mechanical; without quick action; handles. - A switch for controlling and preventing unauthorized interference with the electric equipment of a motor road vehicle comprises a multi-position rotary switch-member to control the various lamp circuits, operated by a detachable key having teeth which engages the switch member and depress it so as first to render active the ignition and starting circuits. As shown the switch member comprises a conducting plate i mounted with insulation on a disc b loose on a shaft c. The switch-member co-operates with a number of fixed contacts to control the lighting circuits. It is operated by the detachable key d placed on the shaft and held in place by a spring plunger f and slot e. The action of inserting the handle couples it to the disc b and depresses the disc against the action of spring s so that it engages with the spring pin k connected with the ignition terminal m and removes a shoulder v from an earthed plate l thereby rendering active the ignition circuit which, when the handle is off, is automatically earthed. Contact pins in association with the starting and other circuits are similarly rendered active when the handle is pushed into place, but the pin u associated with the lighting circuit always engages the contact-member. A spring- pressed plunger r coacting with depressions in a flange q of the disc b serves to determine the various switching positions.
