Title: Perforated arch-shaped fill bar for splash type water cooling towers
Inventor: KINNEY OHLER L JR
IPC: F28F25/08
Filed: 1992-04-08
Abstract: Improved synthetic resin splash-type fill bars (32) for water cooling tower fill assemblies (26, 28) are provided which give enhanced cooling results over virtually the entire range of duty conditions encoun-tered in commercial practice. The bars (32) are prefer-ably integrally formed of PVC and present a dome-like cross-sectional configuration, with an imperforate, fore and aft extending upper apex section (36) and downwardly and outwardly diverging, apertured sidewalls (38, 40) terminating in bifurcated feet (42, 44). The sidewall apertures (50) are nominally circular and are arranged in staggered rows to maximize dispersal of descending hot water in a tower fill. The bars (32) are advanta-geously used in crossflow cooling tower (10), and are preferably oriented transverse to incoming cooling air currents entering the fill assemblies (26, 28) of the tower (10).

Patent CA-2069808-A1 (CA)
Title: Analogue-to-digital converters
Inventor: THURSTON ANDREW M
IPC: H03M3/02
Filed: 1992-05-28
Abstract: P/8677/SPECIAL/us ABSTRACT   (Figure 3) Analogue-to-Digital Converters An  analogue input is converted to digital data output with a  null in the quantisation noise corresponding to  the frequency of the intended analogue signal.  This is achieved by feeding  back  the  digital  output to  be  combined,  in analogue  form  with  the   analogue  input,  the  resulting difference signal being fed through a loop filter.  The loop filter may include resonant circuits e.g.  parallel resonant circuits.   To  reduce  the  phase change at  high  and  low frequencies from ?90°, which could cause instability, but to avoid the  problems of having a resistor in series with  the resonant  circuit,  which  would cause any input  or  output capacitance  to ground of adjacent buffers to degrade the  Q factor  and the notch shape, the resonant circuit on the one hand and  resistive  means on the other hand  are  connected between  the ground and the inputs of a pair of differential inputs such as on a buffer.  Alternatively, a signal derived from the  digital  output  may  be  used  in  place  of  the resistive means.

Title: Transesterification and other conversion reactions of acid derivatives, using an amidine
Inventor: DRAUZ KARL H
IPC: B01J27/24
Filed: 1992-07-14
Abstract: ABSTRACT OF THE DISCLOSURE    Optically active substances and biomolecules such as peptides, amino acids and nucleic acids are sensitive to elevated temperatures, extreme pH values and/or long reaction times. During chemical synthesis, therefore, these molecules easily become racemised or denatured.  The inventive method provides mild reaction conditions for saponification, ammonolysis or transesterification of acid derivatives or splitting of polymer-bonded molecules.  Transesterification, saponification or splitting of polymer-bonded molecules, e.g. in Merrifield synthesis, is brought about by combined use of an amidine base and a metal compound in the presence of an alcohol or water.  When amino acid or peptide esters are saponified, the splitting is brought about with lithium hydroxide alone under mild conditions.  The use of an amidine base, more particularly DBU or DBN, in combination with the metal salt accelerates the reaction so strongly that even sensitive acid derivatives can be reacted under mild conditions.

Abstract: RECEPTACLE FOR STORAGE AND DISPLAY OF NOTIONS     ABSTRACT OF THE DISCLOSURE      A receptacle for storage and display of needles has a flat rear panel of cardboard and a flat front panel of light-transmitting plastic material.          Each panel has a first section and a second section, and the first sections are bonded to each other except to define a first chamber with parallel pockets for first portions of needles.  The second sections are separably bonded to each other and define a second chamber for second portions of needles.  The second section of the rear panel has a first leaf which can be pivoted away from the second section of the front panel, and a second leaf which can be pivoted relative to the first leaf and carries a tongue at the junction of the two leaves.  The second section of the front panel has a first flap which can be pivoted away from the rear panel and away from the second portions of the needles so that such second portions become accessible upon pivoting of the first flap and the first leaf away from each other and away from the needles. A second flap of the second section of the front panel can be folded over the second portions of the needles and can be retained in such position by the tongue of the second leaf upon pivoting of the first flap back to its original position adjacent the second portions of the needles.

Title: Optical clock extraction
Inventor: BARNSLEY PETER E
IPC: H04B10/61
Filed: 1992-05-07
Abstract: In a high speed optical clock extraction arrangement, an incoming digital signal is divided between two paths (11, 25). The signal on one path (25) is fed direct to a receiver (203), while the signal on the other path (11) is fed to a non-linear optical amplifier (1) which has separate gain and absorbing regions. The non-linear optical amplifier (1) is triggered by the incoming signal to pulsate at a clock frequency contained in the signal, and the resultant strong output clock signal is coupled into the path (25) carrying the incoming signal to the receiver (203). The non-linear optical amplifier (1) can provide a very high frequency clock output as a result of selective modification of the carrier lifetime.
