Patent DE-4009970-A1 (DE)
Inventor: TYMIEC MARIAN DR
IPC: A61B5/022
Filed: 1990-03-28
Abstract: In conventional processes for measuring blood pressure, a pressure cuff is applied to an extremety such as the upper arm or a finger and all the blood vessels supplying this extremity are completely or partially compressed for the entire duration of the blood pressure measurement or at least periodically. Until now, it has not been possible to measure blood pressure continously without considerable damage to the patient. The process for measuring blood pressure according to the invention is monoarterial and therefore the supply to the corresponding extremity is never cut off. To determine the blood pressure curve, given characteristic values, such as maximum amplitude, for consecutive blood pressure pulses are compared and used to determine the true pulse pressure curve.
Patent DE-4013925-A1 (DE)
Inventor: GROSS RICHARD A
IPC: B65D47/20
Filed: 1990-04-30
Abstract: A pivotable dispensing closure includes a removable tear tab (50) on the closure actuator (20) or on the body (12) of the closure which interferes initially with the pivoting of the actuator on the body. The tear tab (50) is connected to the actuator or body by a frangible bridging means (64) and is positioned between the body and actuator adjacent an actuator finger pad (30). The tear tab makes the closure resistant to premature actuation of the actuator during shipping and handling prior to purchase, and its absence provides evidence that access has been gained to the contents of the associated container. <IMAGE>

Title: Four-stroke cycle IC engine - has geometrical expansion stroke greater than geometrical compression stroke
Inventor: SCHALL REINHARD
IPC: F02B75/32
Filed: 1990-05-08
Abstract: Instead of a circulating thrust piston, a mechanism is incorporated which combines a circulating gear with a thrust piston.
