Title: Circuit arrangements for discharging capacitors by means of a relay
IPC: H01H9/54
Filed: 1983-03-22
Abstract: 1. Circuit arrangement for discharging capacitances by means of a relay, a reactor (33) and a resistor (11) being arranged in series with a contact (a) of the relay (A) and an RC series circuit (15, 23) being provided in parallel with the contact (a), in particular for the automatic closing of an interrupted pover feeding loop before the point of interruption in the operationally provided pover feeding loop of a pover feeding facility, in which arrangement the reactor (33) exhibits a core of saturable magnetic material, characterized in that the inductance of the unsaturated reactor (33) is of such a magnitude and the RC series circuit (15, 23) is dimensioned in such a manner that an arc produced at the contact (a) when the contact (a) closes is extinguished after the vinding capacitance of the reactor (33) has been charged and the capacitor (23) of the RC series circuit (15, 23) has been discharged, and that the capacitor (23) is dimensioned of sufficient size for the voltage produced across the RC series circuit (15, 23) after the extinction of the arc to remain below the minimum value of the flashover voltage of the contact (a) during the closing process of the contact (a), in which arrangement the voltage/time area produced up to the saturation of the reactor (33) is of such a size that the saturation occurs only after the closing of the contact (a).

Title: Cicuit arrangement for automatically closing a remote power supply loop by way of substitution
IPC: H04B17/40
Filed: 1983-03-28
Abstract: A circuit for automatically closing a backup remote feed loop upon interruption of the remote feed loop of a remote feed device for supplying electrical users by means of DC series feed has a holding winding and a response winding disposed in a longitudinal arm of a switching relay, the contact of the switching relay being disposed in a cross-arm in series with a choke coil. The relay operates with a very low voltage drop at the holding winding and occupies a relatively small volume. The circuit can be utilized as an auxiliary relay controlled by means of a delay circuit for selectively cutting in and cutting out the response winding of the relay, particularly in remote feed repeaters or regenerators.

Abstract: A stable aqueous latex of a copolymer containing at least 
40 percent by weight of a polymerized olefinic unsaturated 
nitrile is described. The copolymer comprises a main polymer 
core of from 40 to 100 percent by weight of the polymerized

Abstract: Die Vorrichtung zum lösbaren Befestigen eines schei­
benförmigen Werkzeugs, vorzugsweise einer Schleifscheibe 
(6) od. dgl. an der Arbeitsspindel eines kraftgetriebenen 
Handwerkzeugs, insbesondere eines Winkelschleifers, be­

Schließteil (8). Letzteres besitzt die Form einer ringformigen 
Scheibe mit einem axial abstehenden Bund (7). Dieser greift 
in die Bohrung (5) der Schleifscheibe (6) od. dgl. ein. Das 
Schließteil (8) ist auf den zapfenförmigen Ansatz (3) des 
Grundteils (1) aufsteckbar, wobei ein Steg (12) in eine 
radiale, in Achsrichtung randoffene Aufnahmenut (11) des 
zapfenförmigen Ansatzes (3) eingreift. An die Aufnahme (11)

Title: Method and apparatus to seal coated paperboard materials
IPC: B31B50/00
Filed: 1984-12-21
Abstract: A method and apparatus for forming a seam on a 
thermoplastic coated container, which container has been 
formed from a single blank (6) or a continuous by bending a 
substrate member (4) from which container was formed and 
overlapping edges (22, 24) thereof to form the seam. 
According to the practice of this invention, the edges (22, 24) 
of the substrate member (4) which are to be overlapped and 
joined to form the seam are each heated, prior to their 
overlapping, by energy from a laser (16) to thereby render 
the thermoplastic coatings on the overlapped portions of the 
substrate member soft and tacky so that they will adhere to 
each other when pressed together and allowed to cool. The 
laser energy is applied by directing an unfocused laser beam 
of 10.6 µm wavelength over a zone of about 1,26399 cm 
(one-half inch) in width to each other to the two edges (22, 
24), the web or blanks (6) being fed along a conveyor (12) 
past the stationary laser sources (16).

Title: Casting method and apparatus
IPC: B22D7/06
Filed: 1984-05-08
Abstract: Castings are produced by sandwiching a central mould part 10 between two outer mould parts 36, 38 during the casting process. The central mould part 10 is then transferred sequentially from between the outer mould parts 36, 38 and subsequently re-located between the outer mould parts in a vacant, relatively cool, and dry condition for the production of a further casting. In one embodiment a plurality of central mould parts are transferred sequentially from the outer mould parts to a removal station 45, a quenching station 50, and a drying station 70, before being returned to the central mould parts.

with an electrically conductive powder (10), applying pressure 
to obtain a compacted powder (11) in the groove (21) and then 
heating the compacted powder (11) to a temperature that in­
creases the conductivity and ductility of the compacted pow­
der and its adhesion to the substrate without adversely affect­
ing the shape or condition of the substrate (20).

Chlorid enthalten, durch Aufschlämmen in Wasser oder Altsäure oder 
Flußmittelbad gegebenenfalls durch Zusatz von weiterer Säure oder von
