Abstract: ABSTRACT OF THE DISCLOSURE   A cation exchange membrane of a fluorocarbon polymer containing pendant carboxylic acid and/or carboxylate groups, preferably having, at a predetermined ratio, pendant carboxylic acid and/or carboxylate groups and pendant sulfonic acid and/or sulfonate groups uniformly distributed therein,is produced by contacting with a reducing agent a fluorocarbon polymer containing pendant groups of the formula:          -O(CF2) mSO2X wherein X is a fluorine atom, a chlorine atom, a hydrogen atom, M or OM in which M represents. a hydrogen atom, a metal atom or an ammonium group, and m is as defined above, and transforming the resultant to a film.  An excellent double-layer type composite cation exchange membrane can be produced by laminating the above-mentioned membrane having pendant carboxylic acid and/or carboxylate groups and pendant sulfonic acid and/or sulfonate  groups  on  a membrane of a fluorocarbon polymer containing pendant sulfonic acid and/or sulfonate groups.  In such a type of double-layer cation exchange membrane, both the two membranes are based on the same kind of polymer and, hence, peeling-off at the interface of the two layers can be well prevented while exhibiting high current efficiency and low electrolytic voltage.

Abstract: Case 04-4267-U.S. APPLICATION OF PAUL A. DIDDENS GRAY TONE RECORDER      ABSTRACT A gray tone recorder uses a selective variation in a recording stylus duty cycle of an electrostatic recording system which recording stylus continues to write at full voltage using a dry toner electrostactically attracted to a recording paper by an electrostatic charge deposited by the recording stylus.  The full voltage recording operation produces a high degree of consistency in the gray level density while the duty cycle variation is effective to vary the separation between record segments by producing variable length segments within fixed recording time periods to achieve a gray scale record. The toner is subsequently fixed or bonded to the paper to create a permanent record.  Input data codes are compared with a sequence of fixed codes during a writing time period to determine the cut-off point of each write cycle.  The system is adaptable for a plural stylii write head by supplying individual stylus write data during each write cycle.

Abstract: ABSTRACT OF THE DISCLOSURE:        A vapor pressure pump for delivering a liquid into a system operating at a higher pressure or located at a higher level by action of a vapor pressure produced from a portion of the liquid to be delivered.  The pump comprises a closed reservoir for liquid, which includes an unidirectional liquid inlet, an unidirectional liquid outlet, a vapor exhaust valve adapted to balance the pressure between the unidirectional liquid inlet and the reservoir during its filling.  The pump also comprises a vapor generator for producing vapor inside the reservoir at a pressure sufficient to force out the liquid contained therein through the liquid outlet, and a control device for operating the vapor generator only when the liquid fed by the liquid inlet has reached a predetermined level in the reservoir.  According to the invention, the vapor generator comprises an evaporation chamber in vapor communication with the closed reservoir, and a device responsive to the control device for sampling a portion of the liquid contained in the reservoir when the liquid in the reservoir  has reached the predetermined value, and for supplying the sampled liquid into the evaporation chamber.          The vapor generator also comprises a heating system for evaporating the sampled liquid supplied into the evapo-ration chamber to produce the pressure vapor required to force the liquid out of the reservoir.

Abstract: ABSTRACT OF THE DISCLOSURE In a system for recirculative precollation copying of a set of simplex document sheets in reverse serial order on a copier providing a choice of precollated simplex or duplex (two-sided) copy sheet copying, more efficient duplex copying without an initial document counting circulation is provided by assuming that the copy sheets selected for duplex copying are non-orientation sensitive copy sheets such as plain paper (rather than special orientation restricted copy sheets requiring consistent inversion for proper output or binding edge orientation, such as sheets prepunched with binder holes, certain preprinted sheets, etc.) by making an initial assumption as to whether there are an odd or even number of simplex document sheets in the set of document sheets before they are counted, by making a selection of whether it is desired to copy odd or even document sheets in the first circulation of the document set for copying, then, in response to this initial assumption and selection and choice of duplex copying, automatically circu-lating the set of document sheets for copying onto copy sheets on the first circulation of the document set before they have been counted, wherein the copying of document sheets on the first circulation is restricted to copying only alternate document sheets in accordance with the assumption and selection, counting the number of document sheets during the first copying circulation to actually determine whether there are an odd or even number, then automatically in the second circulation, in response to this actual determination, copying only the other alternate document sheets (not copied in the first circulation) twice (onto two copy sheets) if the initial assumption was erroneous, or automatically copying all of the document sheets once if the initial assumption was correct. Ones of the two copies of document sheets copied twice in the second circulation are made on the back side of copy sheets copied in the first circulation, and the others of the two copies are made onto additional copy sheets to provide a desired buffer set thereof (preferably of only even pages) enabling duplex copying of all document sheets on subsequent circulations of the document set. The initial assumption and selection are preferably made to avoid ever copying a last (first copied) odd document sheet in the first circulation by copying only the next-to-last and subsequent alternate document sheets.
