Title: Water heating supply installation - has thermostatic valve in consumer run-in pipe and servomotor to adjust drive nozzle cross section
Inventor: BAELZ JUERGEN DIPL ING
IPC: F24D10/00
Filed: 1975-06-09
Abstract: A water heating installation has a jet pump in the run in pipe to the consumer. The drive nozzle cross section of this jet pump may be adjusted by means of a setting or servo motor and which is attached to a bypass pipe braking off the return pipe from the consumer, and acting as a return mixing system. There is a thermostatic valve situated in the run in pipe going to the consumer and operating in relation to the surrounding temp. The servo motor of the jet or injector pump is operated by the difference between the actual pressure in front of the thermostatic valve and a required valve in the reduction sense of the operative drive nozzle cross section at increasing actual pressures.

Title: Quartz Colpitts oscillator with varactor diode - is able to pull frequency over wide range and oscillates at higher harmonic
Inventor: THANHAEUSER GERHARD DIPL ING
IPC: H03B19/00
Filed: 1975-07-31
Abstract: The quartz Colpitts oscillator can be pulled over a width frequency range and oscillates at a higher harmonic. An inductor (L1) is coupled in series with the quartz crystal (Q). The inductor forms a series resonant circuit with the varactor diode used for frequency pulling and with a capacitive voltage divider (C1,C2). The resonant circuit is tuned to the diode average capacitance. A damping resistor is coupled in parallel with the crystal and is larger than the series resonant resistance of the crystal at the working harmonic but still low enough to prevent the crystal from being excited at its fundamental.

Title: Sucrose-based dry beverage mixt. with good colour intensity - obtd. by colour-plating tricalcium phosphate, added to improve free-flow props.
Inventor: BAIL JAMES LEE
IPC: A23L5/42
Filed: 1975-09-22
Abstract: A dry beverage mix contains sucrose (I) at least partly as crystals colour-plated by deposition of colour from aq. soln. ad a small amt. of finely-divided Ca3(PO4)2 (II) homogeneously dispersed, the (II) particles also being colour-plated before blending and some fo the colour originally plated onto (II) is transferred to the surface of the coloured (I) particles. In fruit-flavoured mixes: a greater colour intensity is thus achieved compared with colouring (I) only. The whitish shade of (II) (added to improve free-flowing characteristics) is offset; reflectance is reduced and minor additives can be thoroughly blended without loss of hue by attrition milling (if coloured (I) crystals are broken their exposed uncoloured surfaces are coloured by transfer from (II)). Amt. of soln. required to colour-plate (I) is also reduced.

Patent DE-2608375-A1 (DE)
Title: Rollover protection frame for tractor - with friction grip sliding joints to absorb impacts until movement halted by stops
Inventor: PIEROTH OTTO
IPC: B60R21/13
Filed: 1976-03-01
Abstract: The tractor cab is protected by a rollover frame with uprights secured on the axle assembly and with cross struts to support the roof. The coupling between the uprights and the cross struts acts as a clamp to grip the cross struts, and is tightened by bolts (11). If the vehicle rolls over then the lateral impact on the frame causes the clamp to slide. The frictional force serves to absorb the impact. The amount of sliding is limited by stops (13) on the cross struts. The clamp enables the frame to be assembled without drilling the frame members. Damages frame members are easily replaced.
