Title: Automatic determn. of carbon di:oxide content, esp. in beer - by abruptly enlarged detenting chamber connected to pressure gauge
Inventor: WIELAND DIETER
IPC: G01N7/14
Filed: 1979-05-16
Abstract: A housing forming a detenting chamber, to which a feed and a drain line are connected, for a fluid, esp. a beverage, the CO2 content of which is to measured, has two hollow cylindrical chambers in each of which a plunger is positioned. These are in line one behind the other, are rigidly attached together, and their dia are different. The detenting chamber extends between the facing front faces of the plungers, and is connected at one end to the fluid inlet and at the other to the fluid outlet. The feed line passes through one plunger and the drain passes through the other. The plungers act as shut-offs so that in a first position the fluid feed and the fluid drain are open, whilst when the plungers are displaced by an automatic control mechanism into the second position, the inlet and the outlet are closed. The detenting chamber can be connected to a pressure gauge and to a thermometer, and in the first position of the plungers, it has the min vol, whilst in the second position of the plungers its vol is max. Used for determining the carbon dioxide content of a liq such as beer, flowing in a pipeline or contained in a pressure vessel, at predetermined intervals.

Title: Viscous paste drying method - by heating in vacuum after forming azeotropic mix. with added organic solvent
Inventor: LIPP EBERHARD ING GRAD
IPC: A23L27/10
Filed: 1979-06-15
Abstract: Viscous pastes such as hydrolysed proteins and/or meat extract which tend to agglutinate by the effect of exothermic heat when the moisture content ops, are dried by first adding an organic solvent to the damp paste. The solvent, pref. isopropyl alcohol, methylene chloride or acetone, is a low-boiling substance which forms with the water an azeotropic mixt. which is mixed with the paste to a uniform dispersion. The subsequent drying is pref. done in a vacuum. This saves the labour intensive drying in thin layers on sheets in drying cabinets at 300-330 K which requires many drying cabinets andcalenders. It saves labour, time, capital and energy.

Title: Vehicle fuel consumption instrument - has analogue display of digitally measured summed pulse values using LED or moving coil meter
Inventor: KIRCHER ULRICH
IPC: G01F15/06
Filed: 1979-07-28
Abstract: The vehicle fuel consumption measurement and display arrangement involves measurement of consumption over successive equal fixed distances and determination of impulse summations for each distance. It retains the measurement principle of the arrangement in patent DE2741118 but achieves clarity of display by using an analogue rather than a digital indicator. The impulse sum is converted into an electrical parameter, e.g. a voltage, which is then displayed on an analogue or quasi- analogue indicator, e.g. using light emitting diodes each corresp. to a measurement value. Intermediate parameter values can be displayed by the simultaneous illumination of two light emitting diodes since they have a slow transition arrangement. Alternatively, an electrical needle pointer instrument may be used (e.g. a moving coil meter).

Title: Seat belt rewind mechanism driven by DC motor - automatically reels in belt when fastener is released
Inventor: ZUEDNER WERNER
IPC: B60R22/48
Filed: 1980-05-21
Abstract: The motor replaces the more conventional winding mechanism operated by a coil spring. The advantages offered by the motor drive are that the recoiling torque is independent of the length of belt which has been unreeled such that the tension is the belt when in use can be set at a low value, and that operation is quieter. The motor is coupled to the shaft of the drum on which the belt is wound when not in use, typically the coupling is through a reduction gear. The motor supply is switched off when the belt is in the fully reeled-up condition. To unreel the belt it can be pulled against the torque or more preferably, a slipping clutch may be provided. When in use, the motor torque may be reduced, or the motor switched off, by switches in the seat belt fastener.
