Inventor: FEDERMAN JAY L
IPC: A61K49/04
Filed: 1992-02-19
Abstract: Foreign substances may be removed from a mammalian body cavity containing an aqueous phase by injecting into the cav-ity a water-immiscible, optically clear, biocompatible debridement fluid to at least partially displace the aqueous phase; and rem-oving the aqueous phase and the foreign substances. In addition, a method is provided for visualizing a transparent foreign sub-stance in a mammalian body cavity using a water-immiscible; optically clear, biocompatible fluid having a refractive index different from that of water. The debridement fluid may also be used to reposition desirable substances, such as a lens in an ocu-lac cavity, or to remove a secondary membrane from a cavity lining or structure. Preferably, a liquid heavier than water, such as a perfluorocarbon liquid, is used as the debridement fluid.

Title: Flow control system
Inventor: TIMPANY PETER L
IPC: B01D21/00
Filed: 1993-10-19
Abstract: ABSTRACT    Existing   devices  for  controlling  flow  in   water   and wastewater   treatment   systems   utilize   mechanical   valves, adjustable  height  weirs  and  gates  which  are  expensive   to manufacture  and  maintain,  and in some  circumstances  such  as during  winter,   difficult  to  operate.   A  relatively  simple substitute for such devices to control the flow from one zone  or area  to  another includes a casing defining a  weir  chamber,  a submerged weir in the chamber, an inlet on one side of the casing for introducing liquid into the chamber, a liquid outlet from the chamber on the other side of the weir, connected to a second zone or  area at a flooded level below the liquid level in the  second zone or area,  and a duct in the casing for introducing gas under pressure into and out of the chamber for actively controlling the liquid  level in the chamber and consequently the flow of  liquid over the weir between the inlet and outlet.  The use of the above described  apparatus involves a novel method of  controlling  the flow of liquid over a weir.

Patent CA-2127483-A1 (CA)
Inventor: TAGUCHI TETSU
IPC: G10L19/113
Filed: 1994-07-06
Abstract: In a speech signal encoding system comprising a maximum similarity series extracting unit (50) for producing a series of excitation pulses appearing at an equidistant time interval and an identical amplitude, the maximum similarity series extracting unit sums up, as a waveform, a series of autocorrelation coefficients to produce a series of summation result coefficients. The autocorrelation coefficients correspond to polarized pulses which are equal to one another in pulse interval and pulse amplitude. The polarized pulses form a plurality of pulse sequences which have phases different from one another. The maximum similarity series extracting unit extracts a polarity of each of the polarized pulses by the use of a dynamic programming method using a degree of an accumulated similarity as an evaluation measure and selects, as the excitation pulse series, one of the pulse sequences which has a maximum waveform similarity between the summation result coefficient series and a series of cross correlation coefficients.

Title: Process for producing and processing wash water in a washing installation, and washing facility
Inventor: LAUER GUENTER
IPC: C02F9/00
Filed: 1993-05-28
Abstract: A b s t r a c t The invention pertains to a process for the production and processing of wash water for a washing facility, in particular a car washing facility, in which the wash water is used in at least of washing operation for the cleaning of a motor vehicle or the like and is drained off after each washing operation. In order to use only comparatively small quantities of the wash water,  in accordance with the invention it is provided that the washing water that is drained away is reused,  in an essentially closed water circuit, for subsequent washing operations, that for that purpose the water that is drained away is collected and fed to a filtering facility or a similar kind of treatment apparatus, and that at least a partial quantity of the filtrate or similar kind of pure water that is generated in the treatment apparatus is fed to at least one subsequent washing operation as wash water. The invention also pertains to a washing facility, in particular a car washing facility with at least one spray head or similar kind of wash water outlet, which is provided for bringing the wash water out onto a motor vehicle or a similar kind of object to be cleaned. What is characterizing about the washing facility in accordance with the invention is the fact that it has a collection arrangement for collecting the wash water after each washing operation, that the collecting  arrangement  is connected  with  a  water  treatment apparatus for the treatment of at least a portion of the collected water, and that the filtrate or pure water outlet of the treatment apparatus is connected with at least one wash water outlet of the washing facility. In the washing facility in accordance with the invention, the wash water that is needed is thus used in an almost closed water circuit.
