Title: Shuttering plates for concrete made from foam or hard plastics matl. - have at vertical and horizontal edges keying features for joining purposes
Inventor: LOBMEYER JAKOB
IPC: E04B2/86
Filed: 1973-10-03
Abstract: The shuttering panels made from foam plastics or from solid plastics are used for making double wall shuttering units, using panels which have at their vertical ends dovetailed or cylindrical keying slots for accommodating matching locking profiles at the end of adjacent shuttering panels. The horizontal edges have similar keying features and keying slots. The flat walls of these plates have shallow dovetail grooves which taper downwards. These keying features on the panel surfaces are used for attaching layers of plastic. In addition these keying features ensure that the shuttering panels remain firmly in contact with the concrete even if the plastics shuttering panels are distorted due to thermal changes. The concrete which fills these grooves on pouring also prevents upwards floating of these lightweight shuttering panels.

Title: Pressure gas A.C. switch - has switching contact engaging piston in gas pressure chamber with adjustable piston latch
Inventor: KESSELRING FRITZ DR
IPC: H01H33/915
Filed: 1973-10-18
Abstract: The pressure gas switch has a chamber in which moves a piston, coupled to the switching contact owing to the gas pressure increase. The gas pressure rise in the chamber begins in the zero passage of the current to be broken. An adjustable latch releases the piston only when the pressure has attained a preset value after a given time period, equal to one quarter of the cycle period of the current to be broken. This value must coincide with a specified current phase shift. The switching gas pressure may be limited to the preset value in the chamber by a specified device. The latch may be controlled by a magnetic system, energized by the phase-shifted current and arranged in a space magnetically screened from the current to be broken.

Title: Rotating spindle with electromagnet controlled axial position - soft iron disc rotates on spindle between annular windings
Inventor: BRAUN WERNER DR-ING
IPC: F16C39/06
Filed: 1973-11-03
Abstract: A rotating spindle for a sealless rotary pump is positioned both axially and radially by means of a soft iron disc mounted coaxially on the spindle by a ring. The disc rotates in an axial space formed between two annular magnetic cores which have annular electrical windings disposed inside them to produce two toroidal magnetic fields each toroidal magnetic circuit being completed by way of the disc. In this manner radial movements of the spindle are avoided by the production of induced currents in the disc which beget a centring effecting on the spindle. Axial movements are prevented by known control circuits which adjust the currents in each of windings in response to axial movements of the spindle.

Title: Lamp control switch for vehicle direction indicators - has non stable multivibrator as impulse generator in series with current coil
Inventor: SCHULZ HORST
IPC: B60Q11/00
Filed: 1973-12-21
Abstract: The lamp switch has fewer switching contacts and therefore increased reliability. A resistance-Diode combination is connected to a contact. When the contact is closed the diode is in the non-transmitting mode. A condenser then loads the astable multivibrator via a resistor. When the contact is open a voltage divider controls the impulse time of the resistance diode combination. The loading applied to the multivibrator is then limited by the maximum permitted voltage that may be applied to the resistors. The frequency of the lamp signals is the reciprocal of the periodic time of the multivibrators.
