Abstract: 243,061. Yamamoto, S. Aug. 20, 1924. Cooling air, tubular apparatus for; cooling air by direct contact with cooling medium.-In a process for cooling air and regulating its humidity, the air is dried by passage through alternately used chambers 1, 2 containing fuller's earth, Florida earth, or other acid clay absorber, and is cooled and remoistened by contact with sprayed water in a heat-insulated chamber 6, the heat of absorption imparted to the air in the absorbing chambers being removed by causing the air to pass through a nest of cooled tubes on its way from the drying chamber to the moistening chamber. The tubes are contained in a chamber 4 and are cooled by a water spray or air current from a pipe 4<1>. The water for remoistening and finally cooling the air by its evaporation is sprayed from a nozzle 8. The temperature and humidity of the air issuing from the outlet pipe 10 are regulated by varying the supply of water through the nozzle 8. Any water not vaporized is trapped by zig-zag plates 9.

Abstract: An electromagnetic shielding panel (1, 2, 3, 4, P5) incorporates at least two electroconductive coatings (10 and 6, 7,8). In two of the panels (1,2) the coatings are carried on separate sheets of float glass (5,9), one of the coatings 10 being an anti-abrasive coating is on the outermost surface of the glass (9) in the panel arrangement, while the other coating (6,7,8) being a relatively soft abrasive-sensitive coating, e.g. silver, is on the innermost of the glass 5 in the panel arrangements. In other panel arrangements (3,4,P5) the two coatings are located on opposing sides of one glass sheet 9 and on two of the panels (3,4) a plain sheet of float glass (11) is employed to protect the soft silver coating (6,7,8). In another panel (P5) a sheet of glass (9) carrying an anti-abrasive coating (10) is employed. The panels are of the double glazed type (Fig. 1, Fig. 3, Fig. 5) and the laminated type (Fig. 2, Fig. 4). This invention utilises the enhanced capacitive coupling (C) between the two coatings (10 and 6,7, 8) to effectively earth the innermost silver coating (6,7,8) by way of the anti-abrasive coating 10 without any direct electrical connection being required to be made to the innermost coating (6,7,8).

Granted: 1996-06-11
Abstract: A  gas  analyzer  arrangement  for detecting the presence or quantity  of  a  gas  of  interest  includes a source of  electromagnetic radiation for directing a light beam through a light  conditioning  device  such  that the light beam  is collimated  into a  parallel beam of light. The conditioned light beam is then directed through  a gas sample  cell  which  contains  a  sample  of  the  gas  of interest.  The gas  of interest  has associated therewith, vibrational rotational  absorption lines  specific to that gas and which are  effective for  altering the  light beam according to  the absorption characteristics thereof.  The altered light beam  is  then  directed  to  a birefringent etalon device  which has  been sized specifically to match those  absorption  lines  of  the  gas  of  interest.   An electro-optical  modulator   device  associated  with  the birefringent etalon modulates the absorption lines between the transmission  spectra maxima  and a  point between the transmission spectra maxima so  that  an  absorption ratio can be  utilized to  determine the presence or quantity of the gas of interest.

Abstract: In a multiprocessor system comprising a plurality of processors and a main memory common to the processors, each processor comprises at least one vector calculation unit which is specific to a vector calculation and which is independent of the vector calculation units in the other processors.  A register holds a configuration signal representative of configuration of the vector calculation units in each processor.

Title: Audio dosage control system
Inventor: LOVEJOY KIM A
IPC: H03G3/32
Filed: 1991-07-31
Granted: 1995-02-14
Abstract: Microphones (38, 39) sample the sound output from the speakers  (20-23)  of a sound amplification system.   The resulting time domain analog signals undergo  a  Fast  Fourier  Transform  which  yields frequency  domain  signals  representative  of  the intensities of the frequency bands which compose the sound.   The intensities or levels of each band are compared to stored permissible level limits for each frequency band.   Attenuators  (AF1-AF16)  respond to signals indicative of band levels being exceeded by respectively attenuating the frequency bands to which they are tuned so the speaker output does not contain frequencies which exceed permissible limits.  The time weighted permissible averages for each frequency are also integrated to provide for production of signals representative of the cumulative sound dosage.  When total dosage is trending toward exceeding permissible limits for the time during which the listeners are expected to be listening, the cumulative dose signals operate another attenuator (115) to cause the volume emitted by the speaker to drop to a permissible level.
