Patent CA-2088652-A1 (CA)
Title: Improved oxidative coupling dye for spectrophotometric quantitative analysis of analytes
Inventor: YU YEUNG S
IPC: G01N31/22
Filed: 1993-02-02
Abstract: A dye couple, comprising 3-methyl-2-benzothiazolinone hydrazone (MBTH) and 8-anilino-1-naphthalenesulfonate (ANS), is used as an indicator in a reaction cascade producing a strong oxidizing agent, such as hydrogen peroxide or other peroxides or perborates. The strong oxidizing agent reacts with the dye couple to produce a blue dye stuff. The MBTH-ANS dye couple exhibits strong and flat spectral absorption at the region of about 600 to 650 nm. This region is free of blood color interference, which enables one to measure glucose and other analytes that react with an oxidase enzyme to produce the strong oxidizing agent, through the use of LED optics, accurately without much optic calibration. Further, the MBTH and ANS are very soluble in aqueous solution, yet become insoluble upon oxidative coupling. The poor solubility minimizes dye fading, thus providing a stable endpoint.

Title: Low affinity coating blanket for rotary offset presses
Inventor: DEMOORE HOWARD W
IPC: B41N10/04
Filed: 1993-11-03
Abstract: LOW AFFINITY COATING BLANKET   FOR ROTARY OFFSET PRESSES     ABSTRACT         The transfer layer (28) of a coating blanket (10) has a low affinity for liquid coating material or ink, rather than a high affinity which characterizes convention-al nitrile rubber and photopolymer blankets.   The low affinity material, for example a fluorinated polymer or a silicone elastomer, resists wetting by the liquid media, and has a tendency to form a non-spreading bead or droplet of the  liquid coating material on the transfer media surface.   The low affinity surface provides smooth and quick release of the substrate from the nip between the coating blanket cylinder (12) and the impression cylinder (20).  The low affinity transfer surface further inhibits the accumulation of ink and/or liquid coating material, thereby preventing split  images,  ghost  images,  offset images and back-trapping defects.

Abstract: COMPLÉMENT DE SERRURE Dans la plupart des serrures de porte, on sait que le pêne pénètre dans le cadre et que pour ouvrir la porte, il suffit de déverrouiller la serrure tourner la poignée ou appuyer sur la clenche pour ainsi sortir le pêne de la gâche de manière à dégager la porte. La présente invention fonctionne en conjonction avec toutes les serrures qui utilisent le principe du pêne. Elle est novatrice en ce sens qu'elle n'agit pas sur le mécanisme de la serrure mais directement sur le pêne. Tous les pênes étant similaire, le dispositif que nous décrivons ci-après est donc universel. Dans la présente invention, il n'est point nécessaire de déverrouiller la serrure pour ouvrir la porte, en effet, il suffit d'actionner un mécanisme qui se trouve dans le cadre de la porte et dont la fonction est de repousser le pêne dans la porte à l'aide d'un poussoir. Il suffit par la suite de pousser ou de tirer sur la porte pour l'ouvrir. Pour actionner le poussoir, on peut utiliser divers moyens: un moteur (Figure #1), un solénoïde, un électro-aimant, un cylindre pneumatique, ou tout autre mécanisme, l'objectif étant toujours de pousser le pêne hors de la gâche afin de dégager la porte.

Filed: 1993-09-02
Abstract: A drive for a phacoemulsification probe includes a drive circuit for supplying electrical power to the probe, circuitry for sensing the electrical power supplied by the drive circuit to the probe and for supplying electrical signals indicative of the magnitude of the electrical power supplied. A manually operable input device provides a signal indicative of the transducer power level desired by the user of the probe. A control circuit is responsive to the signal indicative of the desired transducer power level and to the signals indicative of the magnitude of the supplied electrical power for providing control signals to the drive circuit to control the power applied in an efficient manner. The drive circuit includes a totem-pale switch, responsive to at least one of the control signals, to apply power in a square-wave waveform, and a switching regulator for supplying a supply voltage to the totem-pole switch. The totem-pole switch has circuitry associated therewith which is responsive to one of the control signals to initially vary the frequency of the square-wave waveform. The regulator is responsive to a second control signal from the control circuit to vary the voltage supplied by the regulator to the totem-pole switch to control the amplitude of the square-wave waveform. The switching nature of this system substantially minimizes the power consumption of the drive circuit as compared with conventional techniques.
