Title: Method and Apparatus for Interleaving Pulses in a Liquid Recorder
Inventor: BECERRA JUAN J
IPC: B41J2/05
Filed: 1996-02-07
Abstract: A liquid recording apparatus ejects droplets of liquid onto a recording medium. The apparatus has multiple liquid emitters whose emissions are activated by multiple power pulses. The power pulses are controlled to maximize the number of emitters which can be simultaneously energized while keeping the instantaneous power usage within prescribed boundaries. The multiple emitters are organized into banks of emitters whose numbers are small enough that all emitters within a bank can receive a correct level of power simultaneously without exceeding capacity of a shared power source. A circuit interleaves the power pulses to the emitters so that no bank of emitters are receiving power at the same instant of time. In this fashion, the recording apparatus can achieve maximum recording speed while employing the smallest capacity power source which is practicable.

IPC: C07C11/24
Filed: 1994-11-14
Abstract: Compensation for catalyst activity decline in multi-bed selective hydrogenation of acetylenes in the presence of olefins by providing inter-bed heating so that the product from the first bed is heated before it is fed to the second bed, and the temperature at which the product from the first bed is fed to the second bed is increased as the catalyst activity declines.  In a modification, when the catalyst is fresh, the product from the first bed is cooled before it is fed to the second bed, but, as the catalyst activity declines the temperature at which the product from the first bed is fed to the second bed is increased, so that after a period of use the product from the first bed is heated before it is fed to the second bed.

Patent CA-2214763-A1 (CA)
Title: Pump for conveying hot media
Inventor: KUHRT HAUKE
IPC: F04D7/06
Filed: 1996-03-05
Abstract: The invention concerns a pump for conveying hot media, said pump comprising a pump housing, a seal housing disposed at a distance from the pump housing and connected to the pump housing via a Chinese lantern-shaped structure and disposed at a spacing from the seal housing, a fan wheel disposed in the spacing, and a shaft which penetrates these parts. The cooling of the seal housing and of the bearing housing is improved in that the delivery direction of the fan wheel extends from the pump to the bearing housing. The drive motor can be screened from the heated air flow by the bearing housing. Owing to a heat-insulating device on the pump housing, the cooling air flow is not heated substantially before it reaches the seal housing. The protective plate surrounding the fan and the seal housing is used to guide the air such that the air drawn in first flows radially to the seal housing and is then deflected axially.
Patent CA-2216994-A1 (CA)
Inventor: ROTHBERG JONATHAN M
IPC: G06F17/50
Filed: 1996-03-27
Abstract: In a specific embodiment, this invention comprises a method for selecting highly targeted lead compounds for design of a drug that binds to a target molecule. The method comprises screening a diversity library against the target molecule of interest to pick the selectively binding members. Next the structure of the selected members is examined and a candidate pharmacophore responsible for the binding to the target molecule is determined. Next, preferably by REDOR nuclear magnetic resonance, several highly accurate interatomic distances are determined in certain of the selected members which are related to the candidate pharmacophore. A highly accurate consensus, configurational bias, Monte Carlo method determination of the structure of the candidate pharmacophore is made using the structure of the selected members and incorporating as constraints the shared selected members and incorporating as constraints the shared candidate phamacophore and the several measured distances. This determination is adapted to efficiently examine only relatively low energy configurations while respecting any structural constraints present in the organic diversity library. If the diversity library contains short peptides, the determination respects the known degrees of freedom of peptides as well as any internal constraints, such as those imposed by disulfide bridges. Finally, the highly accurate pharmacophore so determined is used to select lead organics for drug development targeted at the initial target molecule.
Patent CA-2220923-A1 (CA)
Title: Process of high purity albumin production
Inventor: BURTON STEPHEN JAMES
IPC: A61P17/02
Filed: 1996-02-29
Abstract: A process is provided for the preparation of albumin which has extremely low levels of or is essentially free of colorants, metal ions, human proteins, host proteins, fragments of albumin, polymers or aggregates of albumin and viruses, and which is essentially non-glycated, relatively high in free thiol and with an intact C-terminus. The process comprises passing albumin (preferably expressed and secreted by transformed yeast) through positive mode cation exchange and then positive mode anion exchange chromatography. Other steps may also be employed, for example ultrafiltration, gel permeation chromatography, affinity chromatography binding the albumin (for example using blue dyes) and affinity chromatography binding contaminants (for example using an aminophenylboronic acid resin). Elution of albumin, with a compound having affinity for albumin, from a material having no specific affinity for albumin is also disclosed, as is removal of ammonium ions with a counter-ion.

IPC: A61K38/095
Filed: 1996-06-07
Abstract: Pharmaceutical compositions for orally delivering a therapeutically effective amount of a drug to the colon without significant release of the drug in the upper GI tract after oral administration of the composition are described. The composition is a unit dosage in the form of a tablet that comprises about 0.01 % by weight to about 10 % by weight of the drug that is useful in treating a colonic disorder or that is absorbed from the colon; about 40 % by weight to about 98 % by weight of a hydrocolloid gum obtainable from higher plants; and about 2 % by weight to about 50 % by weight of a pharmaceutically acceptable binder. The compositions are useful for treating lower GI disorders in human subjects by administering a suitable amount to a subject in need thereof. A particularly preferred aspect is the process for preparing such composition in the form of a tablet.

Title: Speed measuring apparatus and toy for measuring speed of moving member
Inventor: OKADA SETSUO
IPC: G01P1/00
Filed: 1997-12-10
Abstract: A speed measuring apparatus and a toy for measuring a speed of a moving member has a quartz oscillator for generating a clock signal which has a predetermined frequency, a CR oscillator for generating a clock signal which has a higher frequency than that of the quartz oscillator, a comparative circuit, connected with the quartz oscillator and the CR oscillator, for comparing the oscillation frequency of the quartz oscillator as a reference signal with the oscillation frequency of the CR oscillator, a corrective circuit, connected with the comparative circuit, for calculating a corrective factor in accordance with a result from the comparative circuit, a measuring unit, connected with the CR oscillator and the corrective circuit, for measuring a speed of the moving member in accordance with the clock signal from the CR oscillator and thecorrective factor from the corrective circuit, and a display unit, connected with the measuring unit, for displaying the speed computed by the measuring unit. Therefore, in the speed measuring apparatus and the toy, the speed can be measured correctly with an increased number of significant figures, and the increase of the cost is suppressed, even if the oscillation frequency of the CR oscillator is fluctuated by the fluctuations of the temperature and the humidity, because the clock signal from the CR oscillator is corrected in accordance with the clock from the quartz oscillator.
