Filed: 1983-05-13
Abstract: The system of mounting the rear wheel of a bicycle of 
the present invention consists of a device adapted to connect 
in a quick and precise way said rear wheel and the frame 
fork, without being obliged however to disconnect the chain 
nor the speed-charge pinion unit from the freewheel of 
speed-change gearing, said members remaining always 
fixed to the bicycle frame, so that the operation of connecting 
or removing the wheel may be easily effected by a single 
person.

Title: Method and apparatus for operating with commutation fault protection a commutation installation composed of several commutation fields, in an electric energy distribution network
IPC: H02H11/00
Filed: 1983-08-03
Abstract: An arrangement for generating in each switching panel of a multipanel switching facility of an electrical power distribution network a digital operating-state image derived from command inputs and switching position signals. The digital operating state image is transmitted to a collecting memory arranged in a coupling panel which produces an overall image of all switching panels; which overall image is transmitted to the individual switching panels at periodic time intervals. A checking procedure is then conducted in the individual switching panels using the overall image. The arrangement utilizes microprocessors which are coupled to one another so as to exchange data via several transmission paths which are one-bit wide. This arrangement obviates the need for an interlock cable harness in the switching panels and cross-cabling between the switching panels.

Abstract: A dry etching method is composed of the steps of 
evacuating the reaction chamber (4) in which a substrate (5) 
to be etched is set, introducing etching gas (1) into the 
reaction chamber, causing the substrate to adsorb the 
introduced etching gas and thereafter evacuating the etching 
gas remaining in the reaction chamber, and irradiating the 
surface of the substrate to be etched with photon energy 
from a source (8) through a light window (10) provided in the 
reaction chamber, to cause etching by the etching gas. A 
process of film formation involves supplying metastable 
molecules, instead of the photopn energy, to react with the 
adsorbed gas to form a film.

Title: Overload snap circuit-breaking switch for domestic apparatuses
IPC: H01H77/04
Filed: 1987-12-19
Abstract: The invention is directed to an overcurrent-protective switch for household appliances such as a vacuum cleaner. The snap switch has a housing in which a contact mounting unit is mounted at one end of the housing and contains one of two current terminals of the switch. The other current terminal is mounted at the other end of the housing and is configured to define a contact-engaging surface. A resilient interrupting contact member is fixedly connected to the one current terminal and has a metal center strip by means of which it is held in one of two end positions. In the first end position, the contact member is held in contact engagement with the contact-engaging surface of the other current contact terminal and, in the second end position, it is disengaged from the contact-engaging surface. When the center resistance strip is cool, the contact member is in its first position and the current circuit between the two current terminals is closed. On the other hand, when excessive current passes through the center strip, the latter heats and expands causing the contact member to snap over into the second position to interrupt the current circuit between the two current terminals. A reset plunger returns the contact member to its first position.
