Abstract: VEHICLE SPEED CONTROL DEVICE                        ABSTRACT         A system for automatically limiting the maximum speed   of  a   vehicle  to  a   predetermined  maximum, particularly suitable for use with off-road vehicles such as  aircraft  deicing  trucks.    The  system  utilizes  a magnetic hall effect sensor to generate a speed signal which  is  compared  to  a  signal  representative  of  a preselected maximum vehicle speed.   In response to the comparison  a  pulse-width  modulated  control  signal  is generated and used to control a transistor in series with the   ignition   coil   primary   thereby  intermittently disrupting the ignition system.

Abstract: ABSTRACT            Lithium-containing   brines   containing   mono   and multivalent cations, especially magnesium, and anions are treated by electrodialysis to effect separation of a lithium concentrate low in multivalent cations from which lithium can be recovered as chloride, sulfate, or carbonate.  Brine containing 0.03 to 15 g/L Li and a ratio of Mg:Li as high as 60:1  is subjected to one or more electrodialysis steps.  The preferred cationic and anionic membranes are those that are strongly acidic and have sulphonic acid radical and trimethylamine derivatives, respectively, as active groups at 3 to 4 milligram equivalent per gram of dry resin and have a matrix of styrene divinyl benzene copolymer on a pvc base.  Electrodialysis is carried  out  at  a  pH  below  7  under  turbulent conditions.   The number  of  electrodialysis  steps depends on the permselectivity of the membrances, the Mg:Li ratio in the feed and that in the concentrate, the latter being maintained at 5:1 or less.   The chloride concentration in the electrode compoartments is maintained at less that 3 g/L.   In multi-step electrodialysis, a portion of the magnesium may be removed in an intermediate stage by the addition of lime,  the lithium in the resulting solution being further    concentrated    by    electrodialysis. Electrodialysis is carried out in at least one unit comprising  a  multiplicity  of  alternating  anion permselective   membranes   and   univalent   cation permselective membranes defining alternating diluate and concentrate cells between an anode and a cathode compartment.   Lithium is recovered from withdrawn concentrate.

Abstract: IMPROVED FLUID CATALYTIC CRACKING       METHOD AND APPARATUS                   ABSTRACT OF THE DISCLOSURE          A fluidized bed catalytic cracking process and apparatus are disclosed.  Hydrocarbon feed and catalyst are introduced into a vertical riser reactor (1).  Catalyst and cracked hydrocarbons exit a downstream end (5) of the riser reactor.  Catalyst is deflected down to a primary stripper (17).  Entrained catalyst, which was not deflected, is separated from the cracked hydrocarbons in a cyclone separator (21) and discharged via a dipleg.  Stripped catalyst from the primary stripper (17) passes to a secondary stripper (23) and then to a first stage regenerator (33), which partially regenerates the catalyst, and a second stage regenerator (29) which completes the regeneration.  The resulting hot regenerated catalyst is recycled to the secondary stripper to aid in stripping and to the riser (1) to crack the hydrocarbon feed.  A mixing tray (31) between the primary and secondary strippers may be used to mix catalyst from the primary stripper, and the cyclone dipleg with hot regenerated catalyst prior to passage of the mixture into the secondary stripper (23).

Abstract: ABSTRACT OF THE DISCLOSURE A method is disclosed for detecting the occurrence of a binding or complex-forming reaction between specific substances by utilizing the binding reaction to complete an electrical circuit, and then measuring a change in the elec-trical state of this circuit.  In a preferred embodiment, a layer of antigen is coated onto a non-conductive base between a pair of electrically conductive layers superposed on the base.  Anti-bodies which react with the foregoing antigen are treated so that they become bound to fine electrically conductive, metallic particles. The electrically conductive particles having antibody bound thereto are then added to the antigen layer deposited on the base and allowed to react therewith.  Electrically conductive particles are thereby bound to the base due to the binding reaction between the antigen and antibody to thereby form aggregates of elec-trically conductive particles which bridge the electrically conductive layers and complete the circuit.  Such a method is highly useful for the detection of antigens in the blood serum of a human patient.

Abstract: FASTENER DRIVING TOOL Abstract of the Disclosure A fastener driving tool of the type utilizing a motor driven energy storing flywheel and a recipro-cating fastener driving ram employs a flywheel having a metal peripheral surface that selectively engages a metal surface of the ram in order to drive the ram into engagement with a fastener to be driven into a workpiece.  An elastic cord returns the ram to a retracted position when the ram is disengaged by the flywheel, and a pair of elastic bumpers are employed to limit the travel of the ram in the direction of the retracted position and the direction of the fastener engaging position.  The ram, bumpers and cords form a subassembly that permits the ram, cord and bumpers to be removed from the fastener as a unit. The cord is made relatively long to reduce the amount of stretch per unit length applied to the cord thereby to increase the life of the cord.  The motor and fly-wheel may be rotated in opposite directions to reduce precessional forces.

Abstract: An industrial process for producing polyols comprises subjecting sugars to aerobic fermentation using Moniliella tomentosa var pollinis in a fermentation medium containing a water-soluble or water-dispersible polymer which is capable of retaining the cells in the fermentation medium. The process is especially suitable for the industrial production of erythritol and/or ribitol. The process overcomes the disadvantage shared by prior proposals wherein cells are lost from the fermentation media through being carried away by the foam produced during fermentation.
