Title: Hydraulic automatic steering for small boat - has wind vane to actuate control pistons via turbine to swing outboard motor
Inventor: ARNDT JUN WALTER
IPC: B63H25/22
Filed: 1976-01-20
Abstract: The hydraulic automatic steering is for sports craft, and is supplied with pressure fluid via a fluid pressure plant, which in turn is actuated by a turbine wheel, driven by movement of the craft through the water. The hydraulic system is fastened to the boat, and may be combined with hydraulic systems already present. A wind vane is turnably held in a hydraulic control unit and actuates a control piston. Turning of the rudder causes the control head to execute a complimentary turning movement, which is used to return the control piston to a zero position, thereby blocking the hydraulic fluid supply or return to the working cylinder.

Title: Video disc reading head frequency characteristic measurement - uses repeated ramp drive to disc and filtering and mixing to remove head harmonics
Inventor: HENKES DIETER
IPC: G11B19/28
Filed: 1976-03-09
Abstract: The disc (1) motor drive (2) is driven through an amplifier (4) by a repeated ramp or sawtooth waveform produced by a signal generator (3) with a repetition period typically of 45 seconds. The same signal is used to drive the X axis or excursion of an output recorder or oscilloscope (13). On the disc, a signal of constant frequency, corresponding typically to 2.5 MHz at 1.5 revolutions per minute, is recorded. The head (5) detects a variable frequency signal from 0 to 6 MHz as the ramp friction drive changes the disc speed, and this is mixed (6), filtered (8) mixed again (9) filtered again, and rectified (12) to produce the 7 excursion signal to the output recorder or oscilloscope (13).

The top edges of the U-clips have slots into which are screwed self tapping screws (13) which serve to secure the trim strip (10). The trim strip is then covered by a central spring strip (14) so that the screw heads are hidden. The U-clips are welded in place if required, and can be located flush with the lip if the lip is cut away at these sites. The trim strip is demountably attached and can be replaced when damaged, or to change the colour trim. The fitting does not present any extra rust spots for the car and is simple to apply in mass production.

Inventor: SPERNER FRANZ DR
IPC: A61C5/77
Filed: 1976-08-27
Abstract: Dental castings are made, e.g. crowns, bridges, prostheses, by melting 5-100g metal or alloy, esp. 20-70g noble metal alloys, or 10-50g Co-Cr alloy, in a ceramic crucible. A high-frequency induction coil surrounds the crucible; and the transition from the solid to the molten state is detected by the sudden increase (Sa) of the current flowing through the coil. Signal (Sa) is used for raising the temp. of the melt is a subsequent prescribed time, followed by casting in a mould. Signal (Sa) can be indicated optically or acoustically; and/or used to start the automatic casting of the melt. A thermocouple is inconvenient in view of the small amt. of the melt; the invention is superior to visual observation which is hindered by slag on the melt.

Title: Single pipe house heating system - has continuous metal water pipe with heat for rooms conducted through support brackets
Inventor: KOPONEN TAUNO KALERVO
IPC: F24D3/00
Filed: 1976-08-27
Abstract: The house with single-pipe mains for central heating or cooling system comprises a continuous metal pipe of constant inside dia. mounted on one or two adjoining walls for rooms to be heated or cooled. The metal pipes of different rooms are connected without valves without metal, plastic or rubber pipes of the same inside dia. to one or more continuous pipe coils which are connected to the main pipe.

The cradles are fixed and do not affect the vol. or pressure of the medium. He at transfer occurs according to whether the rate of flow of air over the surface structures increases or decreases, depending on the heat of the room atmosphere.

Title: Stopping styrene homo- or copolymerisation - by addn. of nitric oxide, esp. in emergency, to liq. or vapour phase
Inventor: WATSON JAMES M
IPC: C08F12/08
Filed: 1976-03-05

Title: Additional acceleration control circuit - regulates motor run-up allowing reliable starting without risk of final overspeed
Inventor: EMILIUS ERWIN ING GRAD
IPC: H02P5/00
Filed: 1977-09-19
