Title: Salts of 3-(cis-2,6-dimethylpiperidino)sydnone imine
Inventor: SCHOENAFINGER KARL
IPC: C07F9/06
Filed: 1993-05-14
Abstract: ABSTRACT          The present invention relates to 3-(cis-2,6-dimethylpiperidino)sydnone imine salts of the general formula I.                                  (I) in which X denotes H2PO4 or             processes for their preparation and their use.  The salts of formula I are not hygroscopic, which makes them more suitable for the preparation of pharmaceutical compositions.  In aqueous solutions they set a weakly acidic pH, favourable for the stability of the sydnone imine and acceptable for parenteral administration.  They lower the blood pressure, the pulmonary artery pressure and the left ventricular end-diastolic pressure, without provoking reflex tachycardia, thus being useful in the control or prevention of disorders of the cardiovascular system.

Patent CA-2115955-A1 (CA)
Inventor: PARRISH GREGORY C
IPC: H04N5/12
Filed: 1994-02-18
Abstract: Successive pixels representing video data in successive lines in a raster scan are buffered. Each of the lines has a sync pulse defining the line beginning. A phase adjustment is determined between the sync pulse, preferably at a particular level in the sync pulse, and an adjacent one of system adjacent clock signals at a particular frequency. The actual or expected phase adjustment between the pixels at the end of each line is also determined. The difference between the phase adjustments at the beginning and end of each line is then determined. Progressive adjustments are made in the phase of each successive pixel in the line relative to the system clock signals in accordance with the number of system clock signals in the line and the determined difference in the phase adjustment between the line beginning and end. In this way, the pixels of video data are synchronized with the system: clock signals. When the actual phase adjustment relative to the system clock signals is determined at the end of each line, the difference in the phase adjustments at the beginning and end of such line is determined from the phase adjustment for such line and the phase adjustment stored for the previous line. When the expected phase adjustment is provided for the end of each line, this estimated value is altered for each line by an amount equal to the actual phase adjustment at the beginning of such line and the estimated phase adjustment at the end of such line.

Abstract: ABSTRACT The present invention discloses a gas venting system for use in metallic enclosures housing electrical circuit breakers of the type having gas vents in the circuit breaker case for venting gases produced during the interruption of a fault current.  The enclosure includes one or more covers which provide access to the interior of the enclosure and one or more vents through which the circuit breaker gases can exit the enclosure.  The gas venting system includes a gas chute made from an electrically nonconductive and substantially flame retardant material.  The gas chute is generally tubular and hollow in shape and has a breaker end aperture and at lease one vent end aperture.  The apertures communicate with one another through the hollow gas chute.  The gas chute is attached to an inside surface of the breaker enclosure such that when the enclosure cover is closed the breaker end aperture is in close proximity to and encloses the circuit breaker gas vents and the vent end aperture is in close proximity to and encloses the enclosure vents.  Any gases produced by the circuit breaker during the interruption of a fault current and exiting through the gas vents in the breaker case must enter the gas chute through the breaker end aperture.  The gas is then directed to the vent end aperture where it exits the enclosure through the enclosure vents.  An electrically non-conductive and substantially fire retardant spark/flame arrestor covers the inside surface of each enclosure vent to prevent molten metal particles form hitting the enclosure and to prevent flames from exiting the enclosure.

Title: Aqueous dispersion of composite particles including polymeric latex
Inventor: EMMONS WILLIAM D
IPC: C09D17/00
Filed: 1992-11-12
Abstract: Inorganic material particles such as titanium dioxide (10) pigment particles (12) are dispersed in an aqueous medium with a polyelectrolyte pigment dispersant (20). A selected, relatively hard, polymeric latex (40), which adsorbs onto the surface of the inorganic material particles in the presence of the pigment dispersant, is added, as well as a film-forming binder (64) to give a formulated coating composition. The strongly adsorbing polymeric latex can include residues of polymerized itaconic acid or dihydrogen phosphate functional groups, or have a high level of acid functional groups or acid functional groups distributed preferentially at the surface of the latex. The adsorbed latex particles space the inorganic particles apart in the coating film (60), improving performance properties. Alternatively, a single selected polymeric latex is used to both strongly adsorb to the pigment particles and to serve as binder, or a mixture of a selected, strongly adsorbing polymeric latex having a low effective glass transition temperature and a conventional binder latex is employed.

Title: Circuit for generating signals in phase quadrature and associated methodtherefor
Inventor: GILLIG STEVEN F
IPC: H04B1/40
Filed: 1993-10-29
Abstract: A quadrature generator (975, 1075) for generating a pair of pulse trains maintained in perfect phase quadrature with one another. The quadrature generator (975, 1075) includes a feedback control loop for altering the duty cycle of an oscillating signal applied to a master-slave flip-flop pair (450, 650) configured to generate a pair of pulse trains maintained in a relative phase relationship. The feedback control loop controls the duty cycle of the oscillating signal applied to the master-slave flip-flop pair (54, 58) which, in turn, is determinative of the phase relationship between the pulse train pair generated by the master-slave flip-flop pair (54, 58). When the pulse trains generated by the flip-flop pair (450) are beyond phase quadrature, a control signal generated by the feedback control loop alters the duty cycle of the oscillating signal applied to the flip-flop pair (450); to alter the phase relationship between the pulse trains of the pulse train pair.

Title: Low toxicity interleukin-2 analogues for use in immunotherapy
Inventor: HEATON KEITH
IPC: A61K35/14
Filed: 1993-04-13
Abstract: The properties of two recombinant human IL-2 analogues with mutations at Arginine 38 (.fwdarw. Alanine) and Phenylalanine 42 (.fwdarw. Lysine) were analyzed and compared to those of native IL-2. These analogues were found to maintain their ability to bind to the intermediate IL-2 receptor, p75, while binding only minimally to the high affinity p55 + p75 receptor complex. The analogues also maintained the ability to stimulate peripheral blood mononuclear cells to generate lymphokine activated killing (LAK). However, IL-1.beta. and TNF-.alpha. secretions were significantly reduced in response to the analogues, as compared to the native IL-2 molecule. These analogues are therefore potentially valuable low-toxicity alternatives to IL-2 in human immunotherapy and adoptive immunotherapy treatment strategies.

Title: Method and apparatus for the measurement of the mass flowrates of fluid components in a multiphase slug flow
Inventor: WATT JOHN STANLEY
IPC: G01F1/712
Filed: 1993-05-20
Abstract: A dual energy gamma-ray transmission gauge (10) includes radioisotope sources (11) for emitting gamma-rays (l3) of two different energies. Gauge (10) also includes a gamma-ray detector which produces signals as a response to the detected gamma-rays. fi single energy gamma-ray transmission (17) is disposed upstream of gauge (10) for providing further signals indicative of the respectively detected gamma-rays. These signals are subsequently directed to a processing computer (16) together with signals indicative of the pressure and temperature of the flow obtained from two sensor means (18, 19). The intensities of the gamma-rays are recorded and thereafter a value indicative of the mass flow rates of oil, water and gas can be calculated. The mass flow rates of liquid phases are calculated at substantially all times, however, the phase fractions of oil and water are determined only when a slug is passing gauge (10) in order to maximise the path length of the liquid phase through which the gamma-rays pass.
