Abstract: An APPARATUS FOR SEPARATING TOBACCO FROM CIGARETTES     Abstract of the Disclosure The separating apparatus is mounted for vibration on a stationary support and employs a pair of vertically spaced screens and a cover plate spaced a preset  distance over the upper screen.  The spacing of the screen from the cover plate is such that the vibrating means imparts a suf-ficient amount of energy into the frame to lift the ciga-rettes on the upper screen off the upper screen to impact against the cover plate.  The bouncing reaction of the cigarettes between the upper screen and cover plate effects an efficient separation of the tobacco from the paper and filter material, if any.  The tobacco passes through the upper screen onto the lower screen and is removed at the end of the frame.

Abstract: ABSTRACT         Valve mechanism supplying creme on the tops of a succession of two rows of cookies for sandwiching.  The cookies are moved along a sandwiching machine by a conveyor beneath a rotating stencil supplying creme to the cookies, under the control of a one-piece valve assuring a uniform supply of creme on the tops of cookies of each row of cookies to thereafter be sandwiched by other cookies sup-plied to the cremed cookies as passing along the conveyor.          The valve is in the form of a one-piece valve block sup-ported at one end and rotationally adjusted to balance the flow through orifices in a stencil sleeve within which the valve is mounted.  The creme enters the stencil sleeve from one end of the tube.  The stencil sleeve has an outlet port for each row of cookies, which in turn supplies the creme to annular orifices in a rotating stencil, rotating at the speed of travel of the conveyor and the cookies carried thereby.  The valve may be adjusted to shut off the flow entirely and proportion the flow between the two orifices to assure the same amount of creme be supplied to the row farthest from the inlet to the valve as to the closer row as the scroll is rotated to supply creme to the two rows of cookies.

Abstract: ABSTRACT OF THE DISCLOSURE        An improved process for the production of halogens and alkali metal hydroxide by electrolysis of aqueous solution-of alkali metal halides in a flowing mercury electrolysis cell wherein the salt solutions do not have to be purified.  The process comprises subjecting the amalgam leaving the electrolysis to decomposition to form mercury and an alkali metal hydroxide solution and subjecting the mercury to anodic polarization in an electrolyte with a counter-electrode maintained at a sufficiently negative potential to remove from the mercury at least a portion of metal impurities contained therein and recycling the purified mercury to the electrolysis cell.  The metal impurities in the mercury are preferentially anodically dissolved in the electrolyte so that the level of impurities in the mercury will be held below the levels which would adversely affect the electrolytic reaction taking place in the electrolysis cell.

Abstract: ABSTRACT             In the known process of co-use of a catechol-monophenol-formaldehyde condensation product and a "RFL" dip for bonding polyester fibres to the rubber in reinforced rubber articles, the use of the condensation product in the form of an alkanolamine salt instead of the ammonium salt, as hitherto used, leads to certain advantages.   In addition to lowering a problem due to the evolution of ammonia fumes, there is on average a slight increase in bond strength and the compositons are more easity cleaned from the processing machinery used.

Abstract: Abstract of the Disclosure Simple and inexpensive steering mechanism for marine craft wherein motion from a manually-operated steering wheel controls a remotely disposed rudder or other steer-ing member.  The present invention is characterized by an absence of gear mechanisms after the steering wheel for "stepping-up" the number of revolutions from the steering wheel in order that the steering member may be moved into steering position without requiring an excessive number of steering wheel revolutions.  In lieu of such gear mecha-nism, a pulley-belt device is employed.  As in the prior art, the stepped-up revolutions are conventionally fed in-to a rotatable flexible shaft assembly; and a ball screw cylinder or the like converts the rotary motion of the stepped-up revolutions into linear motion of a member which controls the steering.  Since the steering wheel controls the direction of rotation of each pulley used in the sys-tem, as well as the direction of rotation of the rotatable flexible shaft assembly and the screw in the ball screw cylinder, all of which rotate in the same direction, it becomes readily known whether a ball screw cylinder con-tains a right or left hand threaded screw member therein, thus facilitating aftermarket replacement of steering sys-tems.  With prior art gear mechanisms, this capability is not readily available.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved industrial process and apparatus are provided for producing chlorine and iron oxide in a multistage recirculating-fluidized-bed reactor wherein ferric chloride in the vapor phase is reacted with an excess of oxygen at tempera-tures from 550 to 800°C.  The improvement comprises utilizing a reactor that includes an initial "dense" zone and a downstream "dilute" zone.  In the dense zone, a fuel is burned, reactants and recirculated iron oxide particles are heated, ferric chlo-ride is vaporized and at least 50% of the ferric chloride is converted tochlorine and iron oxide.  A solids volume fraction from 0.3 to 0.6 and a superficial gas velocity from 0.15 to 0.6 meters/second are maintained in the dense zone.  In the down-stream dilute zone, a solids fraction from 0.005 to 0.05 is maintained, along with a superficial gas velocity from 1.5 to 6 meters/second which is from 5 to 25 times the superficial gas velocity in the dense zone, and the conversion of ferric chloride is continued to greater than 95% completion.
