Patent DE-4322043-A1 (DE)
Inventor: MICHELSON GEORG DR
IPC: A61B3/12
Filed: 1993-07-02
Abstract: In a method for measuring the flow rate of a liquid, particularly of the blood, a frequency shift of a laser beam reflected in the fluid, according to the optical Doppler effect, is determined. It is intended, however, to develop this method and to propose a device for carrying out the method, in order reliably to permit spatially and temporally resolved measurement of the flow rates of the flowing medium. It is proposed that, at each sampling point, a number N of measured values are formed corresponding to the reflected light, N being an integer equal to or greater than 2, and that, from the temporal variation in the intensity of the reflected light thus measured at the corresponding sampling point, the Doppler shift is calculated and the flow rate at each point of the grid field is determined therefrom. <IMAGE>

Patent DE-4341538-A1 (DE)
Inventor: HAMBURG DOUGLAS R
IPC: F02D35/00
Filed: 1993-12-06
Abstract: The internal combustion engine 22 has an exhaust conduit 30, a catalytic convertor 32 and exhaust gas oxygen sensors 38, 36, upstream and downstream respectively of the catalytic convertor 32. An engine parameter controller 40 receives inputs from both the upstream and downstream oxygen sensors (38, 36). A temperature sensor 70 is associated with the downstream sensor 36 and the controller (40) may activate a heater 48 to warm up the downstream oxygen sensor 36 when the temperature sensor informs the controller 40 that the temperature of the downstream sensor has fallen outside a predetermined operating range. The heater may be powered by a signal of variable duty cycle. The controller may rely on the signal from the upstream sensor 38 when both oxygen sensors have a dynamic output and on the signal from the downstream sensor when both sensors emit steady state signals. <IMAGE>

Patent DE-4412804-A1 (DE)
Title: Optimization and heating-cost measurement in central heating
Inventor: NECKIEN EBERHARD
IPC: G01K17/06
Filed: 1994-04-14
Abstract: The invention relates to a circulation pump having a commutated low-voltage motor which performs two functions: the circulation of the heat transfer medium from the boiler or buffer storage to the radiator, and the determination of heating costs in a simple, inexpensive manner. The motor is fixedly connected to the pump impeller which circulates the heat transfer medium, and thus the flow rate can be determined via an electronic rpm indication. The flow rate of all the pumps gives the heating costs, which are charged proportionately for one pump. When using the pump in individual rooms, an energy saving can be expected. The operator of the heating installation can himself determine the running time, as required, by means of a thermostat and a timer. The radiator thermostat is no longer necessary. The pump should run in an energy-saving manner as a result of the following novel feature: the rotor of the motor runs in an air bubble; the air bubble is back pressure. As a result, no absolute shaft seal is necessary. This results in an energy saving.
Patent DE-4417513-A1 (DE)
Title: Container with bar code marking
IPC: B65D25/20

Abstract: During the manufacture of the container a data carrier or encodable element is integrated within it so that the container and the data carrier cannot be simply separated from one another. The information encoded into the element is extracted by a reader and decoder unit. The encodable element remains functional over repeated usage since it is protected from the usual types of damage encountered from wear and tear by conventional elements, which are either stuck or screwed onto the container.

Abstract: The first of two energy absorbent media used, is reversibly deformable and has a first compressive modulus. The second is deformable with a larger modulus. At 50% and 10% compression, the ratio of its moduli is 1.5 at the greatest. The first medium absorbs a first impact energy by compression at least for a time, while the second medium is compressed by no more than 10%. Its deformable volume is dimensioned to absorb no more than 60% of a second impact energy. The first medium is foam with a ratio of moduli between 2 and 3, at 50% and 10% compression. Its modulus is smaller, near 50% compression. Its volume is so dimensioned, that it absorbs a first impact energy, by no more than 50% compression, at least for a time, whereas the second foam is compressed by no more than 10%. A variety of foams may be used, such as polypropylene, polystyrene, and polyurethane foams in suitable half-hard, and EA or 'energy-absorbing' modified grades may be used.
