Title: Safety cut-out switch for car - which isolates battery or generator and links hazard flashers to low power circuit
Inventor: HAHN GUENTHER
IPC: H01H35/14
Filed: 1973-09-04
Abstract: The safety cut-out switch has a cylindrical housing at the bottom of which is an inertial mass. When the inertial mass is displaced by a collision in any direction it moves a support peg from under the spring loaded catch. The catch then drops and cuts off the current supply from the battery by open circuiting two contacts at the top of the housing. In dropping the catch closes two small contacts at the bottom of the housing. This connects a single cell in the car battery to a special low voltage hazard warning flasher, whose power requirements are low enough not to cause an explosion hazard.

Title: Air conditioning system for buildings - passes treated air through external walls to control surface temperatures
Inventor: GUSS SYLVESTER
IPC: F24F7/04
Filed: 1973-09-18
Abstract: A fan takes in ambient air and discharges it through an air handling plant containing a heater and a cooler into passages in the external walls of the building. The flow through each passage is adjustable by a damper. After flowing through the passages the air is discharge to atmosphere through a stack. The air flow through the external walls affects the inner surface temperature and thus the inside comfort conditions.

Title: Sealing profile for shuttering for concrete placing - is made from flexible material in two different stiffness zones for support and for flexible sealing of gaps
Inventor: RIKER RUDOLF
IPC: E04G17/00

Abstract: The seals for shuttering prevent any leakage of concrete and the final product does not require correction work. The sealing section of the profile which has flexible sealing lips is made from more flexible material than the remaining part of the sealing profile. Both materials are firmly connected to produce an integral unit. The sealing profile flanges enclose the edge of the rectangular plate and the sealing profile is firmly nailed on the edge of such a plate. In the free state the groove in the sealing profile forms a dovetail groove with differently sloping edges. The flexible lip angle is greater relative to the vertical line than the same slope on the other flange made of more rigid plastics material. On connecting the sealing profile is stressed and it firmly clamps the shuttering plate edge.

Title: Tube post diverter - has separate guide tubes for use with each outlet but mounted on common carrier
Inventor: KARDINAL HANS-JOACHIM
IPC: B65G51/24
Filed: 1974-02-18
Abstract: The diverter has a pivoting guide tube between a main union and two branch unions, so as to connect it with one of the latter in one position.
