Abstract: An ion exchange membrane which comprises a layer of fluorinated polymer which has carboxylic functional groups, a second layer of fluorinated polymer which has sulfonic or carboxylic functional groups at a surface layer, and a web of support material therein, and which has channels in the membrane which extend from window areas of the membrane to blind areas of the membrane occluded by members of the support material, is described. Precursor membrane which contains both reinforcement members and sacrificial members, and from which the ion exchange membrane is made, is also described. The ion exchange membrane can be used to separate the compartments of a chloralkali cell, and such a cell operates at low voltage, high current efficiency, and low power consumption.

Abstract: An electronic key (A) includes an electrical plug (10) which is connected with the power, and ground, and output terminals of an encoder (20). An electrical jack (30) is adapted to receive the electronic key plug (10) to supply ground and power thereto and receive an encoded signal therefrom. A decoder (50) is connected with the jack to receive the encoded signal and produce an enable signal if the encoded signal has a preselected code. The enable signal is extended by a first latch (54) to an indefinite duration and the extended enable signal closes an enabling switch (56) and disables an alarm control (80). The enabling switch (56) allows an automotive ignition key (60) to operate the automotive ignition (62). When the enabling switch (56) and the ignition key switch (60) are closed, the first latch is reset and a second latch (68) is enabled to continue producing the enable signal of indefinite duration.

Abstract: Filled thermoplastic compositions useful, e.g., as sound-deadening sheeting for automotive carpet are obtained by blending about 5-55% by weight of ethylene/.alpha.-olefin copolymer, the .alpha.-olefin containing from 4 to 10 carbon atoms; about 2-12% by weight of plasticizer selected from the group consisting of processing oils, epoxidized oils, polyesters, polyethers and polyether esters; about 40-90% by weight of filler; and optionally elastomeric polymers.

Abstract: An optical film reader for projecting and enlarging micro copy information recorded in rollfiche format on rolls of photographic film or the like which provides a film transport mechanism enabling rapid manual scanning of the enclosed rollfiche strip in both directions, with instantaneous reversal of the scanning direction without backlash in the film drive. A low glare, high contrast viewing screen is mounted at 45.degree. to the vertical and placed low at the front of the unit perpendicular to the viewer's line of sight. Movable projection optics are provided for scanning of rollfiche microcopy which is wider than that projectable on a fixed sized screen at one given time at a given magnification ratio; the movable projection optics allow projection of the micro copy data or eye-readable index area of the rollfiche by means of a single scanning lever.

Abstract: Process for locating solder on a precalculated position on an electrical terminal. Metal strip stock coated with a thin layer of solder is fed through a strip guide for precisely positioning the metal strip stock between a pair of rollers. A solder wire is cold bonded to the metal strip stock and the strip stock is subsequently stamped into a terminal.

Abstract: Biaxially oriented, balanced, low shrink tension, heat-shrinkable polyolefin film having a shrink percent of at least 7% in both MD and TD at 110.degree. C. and a shrink force of not greater than 2.2 MPa in both MD and TD at 110.degree. C. is produced by a sequential hot/cold/hot/cold treatment of ordinary biaxially oriented, balanced, heat-shrinkable polyolefin film where the film is stretched and relaxed, respectively in the two hot stages of the treatment sequence.

Abstract: The invention provides an improved process for making an iron-activated cathode for a chloralkali cell, and an improved method for lowering the operating voltage of a chloralkali electrolysis cell, which comprises adding to the cathode compartment of the cell a solution of a water-soluble or caustic-soluble ferrite and passing an electric current through the cell. By virtue of the invention, the hydrogen overvoltage in the cell is lowered, and considerable operating improvement thereby attained.

Abstract: Electronic shut-off circuit is provided in a capacitor discharge ignition system for internal combustion engines to protect against excessive high-speed operation. The circuit includes an electronic switching component connected across the main capacitor of the ignition system. A trigger coil is connected in circuit with a control electrode of the electronic switching component. The trigger coil is selected to generate a sufficient voltage to bias the switching means to its conductive state, thereby providing a low impedance shunt path to short the capacitor and to prevent it from discharging its energy into the primary of the ignition coil. A resistance-capacitance network, in circuit with the switching component, serves to hold it "on" until the engine is shut off.

Abstract: Low molecular weight polydisperse isocyanate-functional acrylic polymers are prepared by direct reaction of the monomers, e.g., 2-isocyanatoethyl methacrylate and butyl acrylate, in the presence of a mercaptan chain-transfer agent and a polymerization initiator but in the substantial absence of water and of Lewis-type bases.

Abstract: A pendulum-type product slicing machine is provided wherein the product is carried on a support frame mounted for swinging movement in an arc with respect to a slicing blade. The slicing blade is an endless band which is supported in an inclined plane such that the lower end of the product carrier may traverse the lower run of the blade for complete severing of the product carried thereby. Mechanisms are provided for control of the thickness of the slices and for automatic operation of the carrier.

Abstract: Vegetable proteins may be converted into isolates which are useful for preparing imitation cheese products. These unique isolates are characterized in general as: having an NSI of at least 90, having not been subjected to enzymatic or chemical hydrolysis, forming an insoluble gel when reconstituted in water at a 15% by weight protein isolate concentration and heated to 85.degree. C. for 30 minutes, and yielding a melt value of at least 15 cm.sup.2. The isolates are prepared under conditions which precondition the protein molecules so that they may be converted, upon heat treatment, into protein aggregates which simulate the hydrocolloidal attributes of caseinate. The heat treatment causes restructuring of the proteinaceous molecules into large molecular weight aggregates.
