Abstract: ABSTRACT           A method and system for precipitating vapors from a continuous coater and retrieving suspended mat-ter therefrom. The entrance and exit passages com-municating with a spray coating booth are vented to a scrubbing chamber where a precipitant spray drives the vapors through a precipitant baffle.  Suspended matter in the vapor is thus precipitated and drained into a recovery tank.  The scrubbed vapors are then exhausted up a stack.  In one embodiment of the inven-tion, the vapors are vented through openings in the top of the entrance and exit passages, in which embodi-ment there is also provided an input chamber for receiv-ing the vapors and transferring the same to the scrub-bing chamber.  In a second embodiment, the vapors are vented through openings in the side walls of the entrance and exit passages, in which case they are vented directly to the scrubbing chamber.  In both embodiments, the precipitant spray is directly against the precipitant baffle resulting in the precipitation of large particles, such that there is no requirement for the provision of a plenum chamber or settling area. Additionally, the precipitation baffle is kept clean by the constant spray.

Abstract: ABSTRACT OF THE DISCLOSURE     An exemplary embodiment comprises an acoustic signal pickup, amplification and reproduction sections wherein the latter contains a plurality of sound sources which influence a shared sound transmission arrangement collecting the sound, influencing it upon formation of a specific transfer characteristic.  Given such hearing aids, the originally set fre-quency characteristic should also be maintained given the maximally attain-able output level.  To this end, the disclosure provides two identical sound sources, proceeding from which the generated sound is supplied to the ear with specific adaptation to a particular individual hearing loss. For example, the desired transfer characteristic is achieved by establishing selected differential transmission properties for the respective acoustic channels leading from the respective sound sources to the shared passage leading to the ear.  An inventively improved hearing aid is particularly suitable for employment as a hearing prothesis for hearing-impaired persons.

Abstract: APPLICATION OF                      SAMUEL A. ARCARA            FUEL ENTRAINED OXYGEN COMPENSATION FOR                 CALORIFIC CONTENT ANALYZER                          ABSTRACT   A colorific content analyzer for determining the calorific content of a combustible gas has a compensation means for compensating the analysis of the calorific content for fuel entrained oxygen.  The gas is combusted to achieve substantially stoichiometric combustion by varying the air/fuel ratio supplied to a combustion chamber by a rotary valve which is speed controlled in response to a sensing of oxygen in the combustion products.  A first measurement of the calorific content of the fuel gas is made using a normal operation of the analyzer and a second measurement is made using a known amount of air added by the rotary valve to the combustible gas stream.  The true air/fuel ratio and the calorific content of the fuel gas is then computed using a predetermined relationship among the system variables.

Abstract: ABSTRACT OF THE DISCLOSURE:           The present invention deals with organic titanium-chelates containing, as chelate builders, only acetylacetone and triethanolamine.  They are extremely soluble in glycol-ethers and even a small addition thereof to these new substances effects an extraordinary improvement in the stability of aqueous solutions.  It is preferable to use 50 to 80% solu-tions of these new chelates, from which very highly diluted solutions of extraordinarily high stability may be produced. For example, even after being stored for several months, 1 to 5% aqueous solutions of these new chelate preparations exhibit no precipitation or turbidity.  They may therefore be used very effectively in aqueous systems as cross-linking agents.
