Title: Solid phase enrichment of intact cells using intracellular constituents
Inventor: KALIONIS BILL
IPC: C12Q1/6804
Filed: 1997-01-17
Abstract: The present invention provides a simple, cost-effective method, and kit, for enriching one or more target cells from a mixed cell population. According to the invention, target cells are detected by a detecting agent which attaches to an intracellular constituent of the target cell, for example, a nucleic acid, peptide, protein, etc., in the cytoplasm underlying the outer cell membrane or outer cell wall. The detected cells are then concentrated from the mixed population of cells using a solid phase support system which may include an immunoaffinity or immunomagnetic system. The enriched cells may then be identified and visualized using an identifying agent and a signal generating system. The present invention also provides a method for increasing the sensitivity of the enrichment of cells from a mixed population of cells by amplifying a selected intracellular constituent of the target cell prior to enrichment.

Abstract: A user-authentication system includes an AUD for transmission of dtmf tones to a user-verification system over a telephone network. In a memory module of the AUD, voice and access data are stored for subsequent transmission to a user-verification system. A compensating system associated with the AUD generates two low frequency and two high frequency tones, and selectively amplifies them to varying levels to compensate for transmission efficiencies associated with conventional telephone microphones. The user-verification system further detects unauthorized users, and includes memory storing data relating to access numbers used, and a user's voice, a transmitter transmitting a first signal requesting voice information and a second signal relating to time, a receiver receiving the tones and the signal relating to time, and an analyzer device determining whether the access number used to reach the user-verification system is identical to previous access numbers used, whether the signal relating to time corresponds to the time of user-transmission of the tones, and whether the user's voice corresponds to the stored data. A system for routing a tone signal from the AUD to an intended user-verification system includes a central switch receiving tones from the AUD including an initial alert tone followed by data tones representing voice-related and destination-related data. The central switch includes an analyzer device analyzing the tones, and a routing device routing the tones to a user-verification system in response to the alert tone. A system for performing amplitude equalization associated with each of the user-verification systems has a receiver receiving tones relating to a user's voice, an amplifier generating an amplification factor for each of the tones, and a correcting device using the amplification factors to correct subsequent voice tones.

Title: An improved structure of a waterbed
Inventor: CHOW ANDY
IPC: A47C27/10
Filed: 1998-11-16
Abstract: An improving structure of a waterbed includes a water filling bed mattress, a plurality of transverse partitions, an air bag unit and a bed protecting cover. By installing a plurality of transverse partitions, the vibration of water impact from simultaneously gravitational pressure of the user is relaxed; the stability of the water filling bed mattress can be increased. The high frequency fusion portion of the water filling bed mattress is prevented to be destroyed, thus the water will not leak out. Another, the longitudinal partitions are installed in the medium portion of the water filling bed mattress in order to isolate the transverse vibrations from water in the left and right sides of the bed due to pressure andthe stability of the water filling bed mattress is increased effectively. The longitudinal partitions are formed with the water openings which are not symmetric in the left and right sides for releasing the pressure of the water flow. Moreover, the firmness of the water filling bed mattress can be adjusted by air pressure of the air bag unit so to satisfy the demand of different users.

Patent CA-2265185-A1 (CA)
Inventor: MATTEAU ROBERT
IPC: A24C5/40
Filed: 1996-12-12
Abstract: A non-smokable tobacco product comprises a rod or stick-shaped element of cigarette tobacco with a filter element at one end and both enclosed by a tubular wrapper. The product is rendered unsmokable by perforations extending through the wrapper of the tobacco or the filter element so that when air is drawn through the filter substantially all of the air enters through those perforations, there being insufficient air flow through the tip end to propagate normal cigarette combustion of the tobacco at that location or to permit any appreciable amount of smoke reaching the smoker's mouth. The product is rendered smokable by the user covering the perforated region of the wrapper or the filter element by means of a strip, a sliding tubular band, or a ring which blocks air flow through the perforations and thus converts the product into a self-made cigarette that can be smoked in the manner of a regular cigarette.

IPC: C07D311/72
Filed: 1997-12-04
Abstract: Disclosed is a process whereby d-alpha-tocopheryl succinate (TS) can be crystallized in a short period of time by subjecting a fluid TS at particular temperature to a particular rate of shear for a particular time in order to accomplish crystallization.
