Patent CA-1036725-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE   The salt of a weak acid and a weak base is removed from a solution by contacting said solution with an emulsion.  Said emulsion comprises an exterior phase which is characterized as immiscible with said solution and permeable to the weak acid and/or weak base in their un-ionized forms. One of the species which can permeate through said exterior phase reacts with a reactant present in the interior phase of the emulsion which converts said permeating species to a non-permeable form, i.e., by neutralization, thus providing a continuing driving force for the permeation of said permeating species.  The other nonreacting or nonpermeating species is stripped from solution by passing an inert gas through said solution. Preferably, stripping and neutralization in the interior phase of the emulsion are carries out simultaneously.  By selection of the reactant present in the interior phase of the emulsion, the process of the instant invention may be designed to remove either the weak acid or the weak base in the interior phase of the emulsion.  In a preferred embodiment, ammonium sulfide, dissolved in an aqueous solution, is removed from said aqueous solution by permeating ammonium through the exterior phase of an emulsion and neutralizing said ammonia in the interior phase with an acidic reactant. Simultaneously, hydrogen sulfide is removed by steam stripping or air blowing of the aqueous solution.

Abstract: ABSTRACT OF THE DISCLOSURE           There is provided a self-contained presence detector useful, for example, as an automatic door sensor.  The detector includes light transmitting means, light detecting means, and electrical circuitry associated with the light transmitting and detecting means.  Each of the light transmitting means has a light emitter such as a light emiting diode and a lens assembly to project controlled generated light beams.  The light sensing means has detection areas intersecting in such a manner as to form a detection pattern through a detection area.  In one embodiment wherein the detector is used to control an automatic door, the detector is disposed on a vertical framing mullion or door jamb adjacent the door in such a manner as to minimize accessibility to the detector chassis whenever the door is closed.

Abstract: ABSTRACT OF THE DISCLOSURE:          A process for increasing the exchange yield in ion exchange processes, in which at least one stored reaction fraction obtained in a previous exchange reaction, a solution of exchanging ions supplied from outside and water are delivered to a washed bed which is filled with water and charged with the ions to be exchanged and, after the discharge from the bed of the water and of a solution obtained as product, the same number of reaction fractions as that previously supplied and having the same volume is collected and stored in order to be subjected to a further exchange reaction in an identical manner and same sequence.  The process of the invention is characterized in that a displacement occurring in the direction of flow and relatively to one another of those liquid particles which are delivered simultaneously or in immediate succession to the bed is substantially prevented until the discharge from the container of the bed is reached, and that the co-ion content of the at least one reaction fraction is kept constant by keeping constant the volume of the reaction fraction, of the solution supplied from outside and of the liquids discharged from the system and of the co-ion content of the solution supplied from outside.  The invention enables one not only to operate at the highest possible exchange yield but also to obtain waste products which satisfy the conditions prescribed for environmental protection.

A speaker cone is mounted within the housing and has a rib which engages the pick-up arm when it moves between its first and second positions.  A second gear is rotatably mounted within the housing and has a cam which engages a rocker arm on which a bell is mounted.  The bell moves between a first non-ringing position and a second ringing position as the gear and cam are rotated.  A third gear is mounted for rotation and reciprocation between a first position where it engages the set of teeth on the disc and a second position where it is out of engagement with this set of teeth.  The third gear is constructed to ring the bell when it is rotated and when the bell is in its second ringing position, the third gear normally being urged to its second position.  The disc is movable out of engagement with the stylus of the pick-up arm permitting the latter to move to its first position, while simultaneously operatively connecting the first gear to the second gear.

Abstract: INTERNAL DIVISION ACTUATION OF  VENTILATED FLOPPY DISK STACK               ABSTRACT OF THE DISCLOSURE    A hollow tubular actuator device operates through an enclosure formed by aligned holes in multiple floppy type storage disks.  The disks, separated by interposed ventila-ting spacers, are clamped between inflexible end plates in a closely spaced continually rotating stack assembly.  The actuator preferably rotates with the stack and translates axially relative to the disks and spacers.  The actuator has a slotted opening for transmitting variable pressure to a selected spacer (address) in the stack and thereby varies the aggregate pressure equilibrium in the stack due to centrifugal air flow.  This acts to deflect the orbits of disks peripherally, on either side of the selected address space, forming a gap useful for obtaining external access to otherwise inaccessible storage surfaces adjacent the selected space.
