Title: Reactivation of damaged cells - by exposure to pulsed microwave energy
Inventor: GOLANT MICHAIL BORISOVIC
IPC: C12N13/00
Filed: 1992-01-24
Abstract: Reactivation of damaged cells is effected by exposing them to a series of pulses of microwave energy at a frequency selected on the basis of biological results (sic; see below), monitoring the state of the cells at intervals, and terminating the treatment when the desired effect has been achieved. The microwave energy density is 0.01-10 mW/cm2 and the frequency is 30-60 GHz. The pulse duration is 0.5-3 min. and the interval between pulses is no more than 5-10 times the pulse duration. The total exposure time is no more than 30 min. The frequency is selected by exposing samples of the cells to a series of frequencies within an octave range (esp. 30-60 GHz) and observing the effect. Adjacent frequencies within the range should differ by no more than 20%, esp. 6-7%. USE/ADVANTAGE - The process may be used in the biological food industry (sic) and in medicine (cell types cited in exmaples are phagocytes, yeast cells and bone-marrow cells). Pulsed irradiation is more effective than continuous irradiation in restoring cellular activity

Patent DE-4219857-A1 (DE)
Inventor: KERSTEN JENS-HEINRICH
IPC: B65D83/00
Filed: 1992-06-17
Abstract: The invention relates to a flexible container (10) for dispensing liquid from a delivery aperture (12) on the closure part (14), a venting valve (18) being assigned to a venting aperture (90) of the container (10), which venting valve is opened in the case of negative pressure in the container (10). The closure part (14) is arranged on a metering body (20) which is inserted in a sealing manner in the opening of the container (10) and is provided with two outlet channels (24, 26). The outlet channels (24, 26) serve to deliver the liquid in the form of a jet or of droplets and, by turning the closure part (14), can be connected selectively to the delivery aperture (12) of the closure part (14). The liquid is located in an internal bag (50) which communicates via a shut-off valve (64, 66) in each case with the outlet channels (24, 26). When the container (10) is turned upside down, the liquid can be delivered by squeezing the container walls in the form of droplets or of a jet in dependence on the position of the closure part (14) by opening the corresponding non-return valve (64, 66) whilst the venting valve (18) remains closed. The relevant non-return valve closes automatically while the venting valve opens when the pressure on the container walls is removed. <IMAGE>

Title: Diaphragm-type pump with no seals for liq. or gas - has smooth and flexible main tube with concentric elastic outer end valves and actuated gas or liquid filled pumping chamber
Inventor: BALTUS RENE
IPC: F04B43/10
Filed: 1992-07-13
Abstract: A diaphragm pump has a pumping chamber with suction/pressure valves which are elastically deformed by the operating medium. It has a flexible tube with diaphragm valves at the ends. Concentrically around this, is a tube which is not constricted when unstressed and which has a body on the conveying part of the pump filled with a gas or liq. and connected to an actuating device.

Liquids or gases can be fed into the pumped medium through a microporous tube or fabric; similarly liquids or gases can be extracted from the medium. The pump and valve casings can be made as half-shell construction and applied in a sec. operation. The prods. are slim. The function is not adversely affected by long fibres or solid particles in the pumped medium.

Title: Misfire detection system for IC engine - has monitor detecting variations in engine speed during firing cycles and providing correction for uneven running from mechanical effects.
Inventor: NISHIMURA YUKINOBU
IPC: F02D45/00
Filed: 1992-09-18
Abstract: The engine speed is monitored by one sensor (3) and a processing control (53) computes the variation in engine speed during a firing cycle for each cylinder, or for a set period before and after TDC for each cylinder.
