The filter medium is single-ply so as to be non-entraining.  Each strand preferably has a smooth outer surface for repelling particles smaller than the size of the openings in the filter.  The frame may laterally adjustable, if desired.  In an alternative embodiment, the filter includes a single-ply sheet of a filtering material having openings cut therein.  The filtering material preferably has a smooth outer surface facing the air-flow for preventing the particles from clogging the filter.  The openings may be made in the filtering material by processes such as laser cutting, x-ray lithography, chemical etching, or by stretching a microporous sheet.  The percentage of the filter surface area that is open to air flow is sufficient to enable air flow without the use of mechanical blowing means.
Patent CA-2125200-A1 (CA)
Inventor: BERGER ADAM L
IPC: G06F17/28
Filed: 1994-06-06
Abstract: An apparatus for translating a series of source words in a first language to a series of target words in a second language.  For an input series of source words, at least two target hypotheses, each comprising a series of target words,  are generated.   Each target word has a context comprising  at  least one  other  word  in  the  target hypothesis.  For each target hypothesis, a language model match score comprises an estimate of the probability of occurrence of the series of words in the target hypothesis. At least one alignment connecting each source word with at least  one  target  word  in  the  target  hypothesis  is identified.    For  each  source  word  and  each  target hypothesis, a word match score comprises an estimate of the conditional probability of occurrence of the source word, given the target word in the target hypothesis which is connected to the source word and given the context in the target hypothesis of the target word which is connected to the source word.  For each target hypothesis, a translation match score comprises a combination of the word match scores for the target hypothesis and the source words in the input series of source words. A target hypothesis match score comprises a combination of the language model match score for the target hypothesis and the translation match score for the target hypothesis   The target hypothesis having the best target hypothesis match score is output.

Title: Method and apparatus for testing refrigerant
Inventor: CONDIT DAVID A
IPC: G01N31/00
Filed: 1994-08-05
Abstract: A method and apparatus for testing refrigerant of one type for contamination by refrigerant of another type as would be the case if an air conditioning or refrigeration system charged with a non-chlorofluorocarbon refrigerant received a replenishment charge of a chlorofluorocarbon refrigerant. A sample of the suspected refrigerant mix is exposed to a re-agent that will decompose the contaminant refrigerant but not the refrigerant that is proper for the system. The sample is then tested for a product of the decomposition. If the prod-uct is present, then one can conclude that the contaminant refrigerant is present.
