Patent ES-428360-A1 (ES)
Title: Method of cooling air and apparatus intended therefor
IPC: F24F1/0059
Filed: 1974-07-17
Abstract: A method and apparatus provides conditioning of an air stream by cooling in a regenerative heat exchanger having two groups of channels separated from one another by walls through which heat exchange occurs. The air stream to be conditioned flows through one group of channels while an auxiliary air stream flows through a second group of channels the walls of which comprise wettable material maintained wet by means of water which is caused to evaporate by the auxiliary air stream to result in cooling. The wettable material provides a substantially stationary liquid layer maintained in the channels of auxiliary air flow so that evaporation takes place directly from the walls separating the two groups of channels to obtain high heat exchange efficiency. The wettable material may be wick-like absorbing material layers which eliminate the requirement of continuously flowing large quantities of water so that the evaporative surfaces may be rewetted intermittently and kept wet over a period of time prior to subsequent rewetting. This is accomplished by providing an excess amount of water. In addition, intensive rinsing of the evaporative surfaces may take place to remove dust particles and mineral deposits occurring in the water. The auxiliary air stream may be split off from the stream of air to be conditioned before and/or after the air stream has been conditioned by cooling to provide greater efficiency.
Patent ES-442689-A1 (ES)
Title: Method and apparatus for testing antibiotic susceptibility
IPC: G01N33/15
Filed: 1975-11-17
Abstract: The light scattering of a number of aliquots of a given bacterial/broth suspension, each containing a different antibiotic are rapidly measured and compared with the forward light scattering of a control suspension of the bacteria in the absence of antibiotic. The inhibitory effectiveness of each antibiotic on the growth of the bacteria is then computed from the substantially simultaneous readings and printed out. The bacterial/broth suspension samples are conveniently deposited in a disposable, plastic, transparent, compartmented container or cuvette into which antibiotic discs are introduced into all but one compartment (chamber) from a ganged disc dispenser. After a brief agitated incubation period of about three hours, the covette is inserted in a photometric analyzer which measures the intensity of light scattered at some angle to the incident beam by each sample chamber and compares it with the light scattered at the same angle by the control chamber to which no antibiotic has been added. The relative effectiveness of each antibiotic is computed and recorded to determine which of the antibiotics is most suitable for treating the patient. The partitioned cuvette includes a filling reservoir from which the inoculated broth is introduced as equal volume aliquots into the interconnected lobes of a row of double lobed chambers. Rotation of the partitioned cuvette transfers the equal volumes of broth inoculum from the interconnected lobes to the transparent and separated lobes of the chambers. Then different antibiotic discs are simultaneously dropped within apertured tubes which are located within all chambers except the control chamber. Elution of the antibiotics into the liquid samples begins immediately. The cuvette is then placed in an incubator/shaker for approximately 3 hours at approximately 36 DEG C to promote bacterial growth and antibiotic elution. The light scattering readings are obtained at the end of the agitation/incubation period and the relative antibiotic effectiveness computed in an analyzer into which the cuvette is inserted and indexed past a light source. The light passes through a lens system which directs a beam of light successively through the transparent lobes of the cuvette. The readings are obtained at a predetermined angle of scatter of, for example, 35 DEG . Initial analog signals are converted to binary digits and logarithms to simplify normalization of the antibiotic-mediated inhibition of bacterial growth by the total growth in the control chamber. The normalized growth inhibition values are printed out and rated on a scale of 0 (no inhibition, total resistance) to 100 (complete inhibition, total susceptibility). In addition the total growth, which has occurred in the control chamber during the agitation/incubation period, is printed out as a logarithmic difference (growth index).
