Patent DE-2360583-A1 (DE)
Title: Clock with electronic digital indicator - has manually operated switch connecting cct. to change indication by set amount
Inventor: SCHOEMBURG HANS
IPC: G04C3/00
Filed: 1973-12-05
Abstract: In electronic digital clocks the correct time is shown by numbers formed by light emitting diodes, fluorescent tubes etc. The operating voltage is taken from time measuring apparatus, usually of an electronic nature, via an electronic circuit. To change the time on the clock according to the invention the time measuring apparatus itself is left untouched. Neither is anything done to the circuit between the said apparatus and the time indicator. Instead a special circuit is switched on by a manually operated key or switch which changes the figure elements directly in the way desired. This provides a simple operation for the user and protects the precision of the complicated electronics.

Title: Wire heating element for blower with axial fan - has one or more heating wire spirals arranged spirally around blower axis
Inventor: MAYWALD KLAUS
IPC: F24H9/18
Filed: 1974-02-16
Abstract: The spirals are inserted in holes in the arms of star-like insulating supporting plates, and the arms are held in position by U-shaped clips mounted in a supporting ring; the arms of the U have projections which can be bent at 90 deg. so as to grip additional holes in the insulating plates provided with a step on their edges facing the clip, which limits the insertion of the plate into the clip; in this position the projections and holes are in line with each other, so that the wires may be fed through holes both in the plates and in the clips.

The cap assembly may be produced by injection moulding from thermoplastics.
Patent DE-2447850-A1 (DE)
Title: Stabilisation of output voltage of DC transformer - with chopper of constant working frequency having keying ratio varied
Inventor: KORN JOEL DR ING
IPC: H02M3/156
Filed: 1974-10-08
Abstract: Between the timing generator and the d.c. voltage transformer there is connected a one-kick multi-vibrator with a RC element defining the pulse duration. At each pulse of the timing generator the RC element is excited. The pulse duration defining the "on" period of the d.c. voltage transformer is also influenced by the charge reversing voltage dependent on the input voltage. This is done in such a way that as the input and charge reversing voltages increase the pulse duration of the d.c. voltage transformer decreases. The one-kick multi-vibrator consists of two gates, the first acting as an inverter and the second as a NOR gate.

Title: Low resistance clamp for overhead electric wiper bar - with bracing insert to press clamp edges evenly on bar
Inventor: LAUBE HEINZ
IPC: B60L5/20
Filed: 1974-12-23
Abstract: The overhead electric wiper bar has a carbon strip (1) secured in a metal clamp (2) which grips the dovetail edges of the carbon strip. For improved contact between the carbon and clamp, the clamp is divided at the bottom and after the carbon has been positioned an insert strip (12) is placed between the ends of the clamp to splay the bottom part of the clamp apart. This causes the profiled edges of the clamp to press more firmly into the dovetail profiles. Additional clamping is provided by a C-shaped clamp (14) clipped over the main clamp. The system provies a low resistance clamp for longer liefe, which can even support broken pieces of carbon strip.

IPC: F28F21/06
Filed: 1975-04-07
Abstract: A synthetic covering for heat exchangers and tubes for heat exchangers, comprises a highly elastic layer(b) of synthetic material with a high modulus of elasticity, and a thin coating layer(c) of a material of high tenacity with a low coefft. of friction. Beneath the elastic layer (b) immediately on the inner metallic surface of the tube wall, there is an underlayer(a) of a plastic which, when applied, has a low viscosity. The elastic layer(b) has a structural component(b1) of a material which has a high degree of resistance to change of form at high temps., and an elastic component (b2) of a material extremely capable of adapting itself elastically to change of shape. The lining described is much more resistant to expansion and contraction due to temp. changes, and is uniform in thickness, so that familiar cleaning techniques can be employed. There is less tendency for foreign matter to adhere to the lining, and the friction of the heat exchanging medium is reduced.

Title: Pneumatically activated mechanically operated delay mechanism - has spring wound by air jet discharged periodically from nozzle
Inventor: KLOCKE HARALD
IPC: F03G1/08
Filed: 1975-04-30
Abstract: A conventional mechanism (1) contains an appropriate system of gears and ratchets to give a delayed and prolonged output and is driven by a coiled spring (2). The outer end (3) of the spring is fixed and the inner end is attached to a shaft which has a radial arm (5) attached to it. The arm carries an open box (7) which closes over a jet nozzle (6) when the spring is unwound. The nozzle is connected to a source (11) of compressed air thr resulting jet forces the box (7) and arm (5) away from the nozzle and thus rotates the shaft and winds up the spring. The control valve (10) is operated periodically to wind up the spring as necessary.
