Title: Labeling of hydrocarbons
Inventor: BRINKMAN KERRY C
IPC: C07B63/00
Filed: 1992-05-01
Abstract: ABSTRACT OF THE DISCLOSURE         A population of thousands of hydrocarbons, liquids or gases can be traced from a point of sampling, and back to the originating source by employing combinations of labeling compounds in a base 2 or higher coding system to give Mn-1 possible codes where n is the number of labelers and M is a variable such as concentration, enabling any specific hydrocarbon thus sampled to have its provenance verified in terms of origin or quality; monitoring gasolines at motorist service station sites is a notable example of practice, but other hydrocarbon liquids and gases may be traced.

Title: Powder inhaler
Inventor: MCAUGHEY JOHN J
IPC: A61M11/00
Filed: 1991-09-30
Abstract: A dry powder inhaler (10) consists of a chamber (12) into which powder is introduced from a metering system, and a mouthpiece (26) through which a patient inhales, connected by a duct (16), so that air flows through the chamber carrying the powder into the patient's lungs. Within the duct is an impactor (25) consisting of a plate (27) spaced in front of a similary sized aperture, and between the chamber and the impactor plate is an orifice (18) narrower than the duct, so the air stream is diverted along S-shaped paths to avoid the plate. The presence of the impactor can improve the efficiency of delivery of a drug to the lungs, and decrease the unwanted dose to the mouth and throat, as the latter is principally due to agglomerates or larger particles which are intercepted or broken up by the impactor.

Patent CA-2099146-A1 (CA)
Inventor: JONES MARK A
IPC: H04N1/41
Filed: 1993-06-25
Abstract: An IDCT method decimates a 2-D IDCT into two 1-D IDCT operations and then operates separately on the even and odd pixel input words.   In a common processing step, selected input values are passed directly to output adders and subtractors, while others are multiplied by constant, scaled cosine values. In a pre-common processing step, the lowest-order odd input word is pre-multiplied by ~2, and the odd input words are summed pairwise before processing in a common processing step.  In a post-common processing step, intermediate values corresponding to the processed odd  input  words  are  multiplied  by  predetermined coefficients  to  form  odd  resultant  values.    After calculation of the even and odd resultant values,  the high-order and low-order outputs are formed by simple subtraction/addition, respectively, of the odd resultant values from/with the even resultant values.   The input values are preferably scaled upward by a factor of ~2. Selected bits of some intermediate resulting data words are optionally adjusted by forcing these bits to either "1"  or  "0".     The IDCT system includes  a pre-common processing circuit (PREC), a common processing circuit (CBLK), and a post-common processing circuit (POSTC), which perform the necessary operations in the respective steps.  The system also includes a controller (CNTL) to generate signals to control the loading of system latches and, preferably, to time-multiplex the application of the even and odd input words to latches in the pre-common circuit.

Patent CA-2107167-A1 (CA)
Inventor: KONIECZYNSKI RONALD D
IPC: B05B5/16
Filed: 1993-09-28
Abstract: An apparatus for transferring electrically conductive coating materials, such as water-based paint, from at least one source to one or more coating dispensers or spray guns for discharge onto a substrate includes two "parallel" flow paths, each having a large reservoir pump, which transmit coating material to a common valve which, in turn, switches flow to the coating dispensers from one flow path to the other. Each parallel flow path provides a voltage block between one or more sources of coating material and the electrostatically charged coating material discharged from the spray guns to ensure that there is never a completed electrical path between the source of conductive coating material and the charged coating material during a coating operation. Additionally, a rapid and efficient color change capability is provided for the entire system which permits different colored coating materials to be dispensed from the apparatus herein with minimum downtime of the coating operation.
