Title: Screw, nut and thread rolling die
Inventor: SUZUKI YASUO
IPC: F16B25/00
Filed: 1991-07-12
Abstract: ABSTRACT    A screw having a main thread (2) to be screwed in and a sub-thread (3) formed in the direction opposite to the main thread, which is characterized in that a slant surface (3b) of the sub-thread on the screw-loosening side has a sharp slope whereas that (3a) on the screw-tightening side has a gentler slope.    When such a tapping screw as above is screwed into a pre-drilled hole (4) and the sub-thread (3) advances in the direction opposite to the screwing-in direction thereof while acting like a wedge because the slope of the slant surface (3a) on the screw-in side is gentler.    When the screw is subject to torque  in the screw-loosening direction after tightened, the torque acts on the sub-thread (3) in the tightening direction thereof and, because of the sharp slope of the slant surface (3b) on the screw-loosening side, the sub-thread resists the unscrewing of the screw as if eating into the surface of the pre-drilled hole and prevents the screw from loosen-ing.

Inventor: TRELL ANDERS E
IPC: H04M11/02
Filed: 1991-12-27
Abstract: A B S T R A C T            A method for signalling/communication within an entrance telephone system or similar,  and a system utilizing the method, which facilitates selective communication from an entrance center or central unit (1) to desired and addressed substation (5, 5', 5") via a loop including at least two conductors, and which also facilitates entrance lock opening or similar function from such a substation (5, 5', 5"). After approved  addressing  operation  of  the  central  unit  (1) performed by a visitor, the central unit (1) performs feed of work current to the loop (2, 2') joining the central unit (1) and connected substations (5, 5', 5"), and transmits an address code unique for addressed substation (5, 5', 5"). By means of a signal detecting means (6, 6', 6") only addressed substation (5, 5', 5") then establishes a galvanical connec-tion with the loop (2, 2') and the central unit (1). The central unit (1) performs thereafter generation of a ring signal, detection of "hook off" or other status or signalling changes, and on detection of not completed reply, or termina-ted entrance telephone communication/function, the feed of work current to the loop is interrupted. Address information from the central unit (1) is preferably transferred using a signalling type different from the signalling type whereby substations (5, 5', 5") connected to the loop (2, 2') can influence the central unit (1) during an established connec-tion in order to initiate entrance lock opening or other function.

Title: Method of determining the stroke volume and the cardiac output of the human heart
Inventor: WESSELING KAREL H
IPC: A61B5/029
Filed: 1992-01-28
Abstract: Method of determining the stroke volume of the human heart from the pulse-type blood-stream pressure signal derived from the aorta and consisting in each case of a systolic and a diastolic period. Said method comprises calculating the flow q(t) from the pressure p(t) and integrating the flow over the systolic period, the aorta being regarded as a transmission line supple-mented with a windkessel compliance and the pressure/volume relationship in the aorta as an arctangent relationship. The pres-sure represented by the pressure signal - for each stroke prior to the calculation of the flow - is linearised by means of the arctan-gent relationship, for fixed aorta length, of the aorta pressure cross section, the values, associated with the final diastolic pressure, of the characteristic impedance of the transmission line and windkessel compliance being adhered to or is used without modification. The characteristic impedance of the transmission line and the windkessel compliance are continuously adapted to the pressure of the windkessel compliance for each stroke concerned.  Additionally, to calculate the flow, the flow through the pe-ripheral resistance is added.
