Patent DE-3176106-D1 (DE)
Inventor: CARIM HATIM M
IPC: A61N1/04
Filed: 1981-11-20
Granted: 1987-05-21
Abstract: A non-polarizable electrode is disclosed comprising a metallic sensing element in contact with an electrolyte gel or other conformable, electrically conductive skin-interfacing material containing dissolved electrolyte salt and an oxidizing agent. The oxidizing agent reduces the metal on the surface of the sensing element to a metal cation which reacts with the anion of the electrolyte salt to produce an insoluble compound which is deposited on the sensing element to render it non-polarizable. The preferred embodiment of the invention relates to silver/silver chloride electrodes.

Title: Self-starting brushless d.c. motor
Inventor: VAN HOUT HENRICUS MARINUS
IPC: H02P1/16
Filed: 1982-08-12
Granted: 1986-02-27
Abstract: A motor is self-starting using only one magneto-sensitive element because the motor is of a two-phase type and is provided with a detection device which detects towards which of the two phases the rotor is mainly directed. A presetting circuit compares the detected rotor position with the state of an energizing circuit in order to set this circuit so that the energizing circuit energizes the stator phases for said specific rotor position in such a way that starting of the motor is guaranteed, although initially with an undefined direction of rotation. By presetting the commutating direction of the energizing circuit the rotor subsequently locks the field which rotates in the correct direction if it has started in the incorrect direction.

Title: Method of forming continuous strip of amorphous metal
Inventor: BOSMAN JOHANNES BERNARDUS ANTO
IPC: B22D11/06
Filed: 1983-06-16
Granted: 1986-04-30
Abstract: Continuous strips of amorphous metal are formed by forcing a row of jets of molten metal through a corresponding row of orifices in the nozzle of a reservoir for molten metal onto a chill surface moving transverse to said row and within a distance of 2,5 mm from said nozzle, on which surface the jets join together to form a melt puddle for solidication by very rapid cooling of the metal into an amorphous strip which is carried off by the chill surface. In order to obtain thicker strips than has been possible heretofore, the metal is forced onto the chill surface by at least two parallel rows of jets emerging from parallel rows of orifices in the same nozzle and the melt puddle is formed by the jets of all rows in combination.

Patent DE-3484863-D1 (DE)
Inventor: GREENBERG HARRY B
IPC: C12N7/04
Filed: 1984-06-26
Granted: 1991-09-05
Abstract: This invention relates to processes which are used to produce, isolate, and characterize human rotavirus/animal rotavirus reassortants and to produce live attenuated vaccines and vaccine precursors. In the present strategy there is involved the new use of either (1) high titer hyperimmune antisera or (2) monoclonal antisera to select reassortants with the desired human phenotype. A point of novelty is the finding that antiserum or monoclonal antisera alone, so long as it possesses high titer neutralizing activity against only the 34-38Kd glycoprotein or of the animal parent, is sufficient to use for selection of reassortant rotaviruses with human phenotype. Also, the novel products are live attenuated vaccine precursors and vaccines.

Abstract: A jack for modular plug connectors designed for connection to a printed circuit board includes a housing formed of three parts which when interfitted define a receptacle for receiving a modular plug connector which terminates a multi-conductor cord. A plurality of jack contacts are held through the interfitting relationship of the various housing parts in a manner such that the jack contacts are entirely enclosed within the housing except for the projecting portions thereof which are adapted to be inserted into the printed circuit board. The plug receiving receptacle is partially defined by a surface adapted to provide a backing support for the jack contact portions engaged by the contact terminals of the modular plug connector. According to one embodiment, one of the jack housing parts which substantially surrounds the longitudinal extent of the modular plug connector when the latter is inserted into the plug receiving cavity is formed of a material which is electrically conductive and which provides good electromagnetic and radio frequency radiation shielding. In use, a cord shield terminating contact pin of the modular plug connector may contact one or both of the conductive housing part and a grounded jack contact to ground any electrostatic charge in the cord shield to prevent electrical arcing.
