Title: Protective circuit for smoothing iron - includes two spring loaded contacts supplying power only when iron is handled or rested correctly
Inventor: WIENANDT REINHOLD
IPC: D06F75/26
Filed: 1978-02-17
Abstract: Two contacts in parallel on a smoothing iron ensure that if it is not rested correctly, the current is switched off, so that the possibilities of damage to the linen and more serious fires are completely excluded. Switches are provided under the handle and at the back end of the handle onto which the iron can be tilted backwards and rested temporarily. Thus only when the iron is used or positioned correctly, power is supplied to it.

Title: Two stage water pump for caravan - has stages separately driven with flow directly from one into other
Inventor: BEVIER GUENTER
IPC: F04D13/14
Filed: 1978-06-03
Abstract: A single casing (1) with a cover (2) contains two separate pumps side by side. Each pump has its own electric motor (6) and an impeller (5) on the shaft extension of the motor.

Title: Mandelic acid optical resolution - using optically active 2-benzyl-amino-1-butanol derivs. as resolving agents (NL 8.3.79)
Inventor: HALMOS IMRE AUREL
IPC: C07C51/487
Filed: 1978-09-06
Abstract: Optical resolution of DL-mandelic acid involves reacting DL-mandelic acid with an equimolar amt. of an optically active 2-benzylamino-1-butanol of formula (I), isolating an optically active mandelic acid salt of formula (II), and working this up to give optically active D(-)- or L(+)-mandelic acid (where X is Cl, Br, F, NO2 or CH3).

Title: High resolution, analogue measurement rapid conversion processing - uses low resolution converters and non-linear gain devices
Inventor: BUCHNER KLAUS ING GRAD
IPC: G01R13/34
Filed: 1979-03-28
Abstract: An arrangement processing analogue measurement signals first converts them into digital form for intermediate storage, and later converts them back to analogue form for visual display on a display unit or pen recorder. Higher reduction and conversion speeds are achieved without unduly increasing demand on converter performance. The analogue signals are intentionally distorted prior to conversion by multiplying the low signal values with higher gain than the high values. The distortion is subsequently removed on conversion back into analogue form by reversing the gain variation. The distortion and correction processes involve direct or inverse functions of non-linear exponential or quadratic form. The a-d and d-a converters are low resolution, e.g. 4-bit devices.

Title: Reactor pressure vessel support - by clamp rings straddling welded seams of offtake pipe connections
Inventor: HARAND ELMAR
IPC: G21C13/036
Filed: 1979-04-26
Abstract: Parent Patent DT2850651 described a support for a cylindrical reactor pressure vessel against a biological concrete shield by several horizontal support tubes which extend to fit around the offtakes on the reactor cylinder. The weld between each offtake and its pipe is now straddled by a clamp ring which in turn is supported by the horizontal support tube. This relieves the weld of all load so that it is not necessary to dismantle the support tubes to gain access for a routine inspection of the weld quality.
