Patent DE-2711762-A1 (DE)
Title: Three position switch for AC circuit - has unidirectional semiconductor device coupled to current line terminals
Inventor: LIEBERMAN GILBERT
IPC: H01H9/02
Filed: 1977-03-17
Abstract: The switch housing has a base plate, a cover, terminal clamps and a switching element for the circuit making or breaking. In addition to the switching element (18) it contains a unidirectional semiconductor device (20) coupled to the terminals (12, 14) for the current line (16). The switching element can be brought into three positions. The first two positions are for the circuit making and breaking respectively, while the third position permits reduced current supply to the load. In this position the current is permitted to flow through the semiconductor device. Thus only positive, or only negative voltage components of the individual cycles can flow through the load. A diode is preferably used as the semiconductor device.

Title: Continuous ozonisation process for unsatd. organic cpds. - uses a co-current reactor which dissipates the heat of reaction evenly
Inventor: CARDUCK FRANZ-JOSEF DIPL CHEM
IPC: B01J19/00
Filed: 1977-03-29
Abstract: Continuous ozonisation process, of unsatd. cpds. partic. of long chain cpds. or with high molecular weights such as olefins oleic acid or linoleic acid etc. in the presence of water is claimed. Process consists of causing to react in a co-current way a fresh charge of the mixt. to be ozanised with a gas contg. ozone which has been previously used to ozonise an already partially ozonised charge of the mixt. Simultaneously. a partially ozonised charge is made to react co-currently with a fresh charge of gas contg. ozone. The reaction may be regulated and accelerated such that the heat of reaction is not produced suddenly in a small space, but is spread out through the entire space. The heat of reaction may be dissipated by uniform evaporation of the water without varying the temp. and pressure in the reactor. The system allows a quantitative transformation of the participating products without having to use costly counter-current reactors.

Title: Blade for applying paint to flat surfaces - has internal passageways to ensure even distribution and gap and hole dimensions ensure even paint flow
Inventor: HERMANSON HERMAN A
IPC: B41F31/08
Filed: 1977-05-05
Abstract: The blade for applying paint to flat surface is composed of two strips of material bonded together. The upper strip (4) is provided with a transverse hole (13) midway along its length. This hole (13) runs into two sloping grooves (12a, 12b). A thin layer of material is removed from the triangular surface formed by the grooves (12a, 12b) and the lower edge (14), to form a narrow parallel gap. Paint flows in through the hole (13) and out along the edge (14). The dimensions of the holes (12a, 12b, 13) and the central gap are so chosen to ensure an even flow of paint along the edge (14). Mathematical formula by which these dimensions can be calculated are based on the hydraulic radius, flow or velocity and viscosity of the point.
