Patent DE-2908124-A1 (DE)
Title: Rings of resilient plastics for document file - have ends which hook together and are riveted to file
Inventor: PATERSON DOUGLAS ALEXANDER AND
IPC: B42F13/10
Filed: 1979-03-02
Abstract: A document file has filing rings made from resilient plastics strip. The strip (1) has a hook (3) formed at one end which passes over a small projection (7) at the opposite end and then engages the sloping edge (6) of a slot (4) and so forms a circle. The strip (1) is attached to the spine of the file by a rivet which passes through a hole (11) in the middle of the strip. The width of the strip (1) is increased locally around the edge of this central hole (11). This type of plastics is less likely to damage the documents around the filing holes.

Title: Purificn. of flue gas from fluidised-bed combustor - by contact with iron oxide, vanadium pent:oxide and limestone
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D53/86
Filed: 1979-08-03
Abstract: Removal of pollutants (SO2, NO2, HCl, HF) from flue gases generated in a fluidised-bed combustion unit is carried out by (a) injecting a Fe-contg. material (I) into the hot zone (above 850 deg.C) of the fluidised bed, (b) contacting the gas at 400 deg.C with a V205 catalyst, (c) injecting the gas into a fluidised bed of ground limestone at 180 deg.C, and (d) cooling the gas by heat exchange and separating CaSO4 in a filter unit. Specifically (I) is Fe2O3 and/or FeSO4 or some other Fe-contg. waste product convertible to Fe3O4 at the working temp. The combined catalytic action of the Fe3O4 and V205 provides practically 100% conversion of SO2 to SO3, which reacts with the limestone to form CaSO4 as a useful by-product (e.g. for cement mfr.).

Title: Hose connected to pipe with clip and sealing ring - esp. of elastomer or natural rubber, improves tightness of joint
Inventor: EHRENBERG KURT
IPC: F16L33/18
Filed: 1980-06-30
Abstract: A connection of a hose to a pipe end is effected by means of a hose clip; in the region of this clip there is an elastic sealing ring between the pipe and the hose. Pref. the external and/or internal faces of the elastic sealing ring has a circumferentially grooved profile. The sealing ring may be entirely or partly of an elastic material possessing no cold flow such as an elastomer or natural rubber. The ribs on the outer and/or inner faces may have a zigzag form or an undulating form. In a variant, the sealing ring comprises a metal ring and concentric elastomer or natural rubber ring bonded or vulcanised to it. The use of an inserted sealing ring improves the tightness of the joint over a long period of time as a result of aging of the tube material and also due to temp. differences.

Title: Generator/motor of modular construction
Inventor: GEIGER OTTO
IPC: H02K29/00
Filed: 1981-03-06
Abstract: A generator/motor arrangement has three generator elements and three motor elements which are in each case arranged on a common shaft between stator plates. The units act both axially and radially. In order to achieve magnetic independence from one another in the respective reference system, they are alternately pulsed in the periodic sequence from 120 DEG  and 135 DEG  by a thyristor triode circuit (triacs, bidirectional) in such a manner that a motor torque is produced as a result of the mechanical preset of 15 DEG  with respect to the respective time, which motor torque becomes effective when the generator is loaded and in each case initiates an optimum torque for supporting the externally absorbed mechanical drive energy.

Title: Device for feeding an electrically conductive medium
Inventor: SCHAEFER GERHARD ING GRAD
IPC: B05B5/10
Filed: 1981-03-16
Abstract: In a potential separating device for liquid media, the liquid medium is removed from an earthed feed system (6,14) and fed, via a metering device (5), in a pulsating manner in individual amounts to a container (2) consisting of insulating material. At the same time, the feed opening (4) for the medium which is input in a pulsating manner is arranged inside a Faraday cage (7) of the earthed, electrically conductive container lid. The Faraday cage and the metering device are matched to one another in such a way that the amount of medium still inside the Faraday cage is completely separated from the feed opening. The respective amounts of medium (15) are no longer atomised in the high-voltage field so that unnecessary formation of gas and adverse influences on the medium are avoided. The device is advantageously used in potential separating devices for high-voltage paint spraying systems.

Abstract: 1. Method for the forwarding of emergency calls from persons requiring assistance, in wich method an emergency call subscriber set, which is connected to a subscriber line of an automatic telephone exchange network, after actuation of a sensor automatically selects the call number of an emergency call exchange connected to the automatic telephone exchange network and after the thus effected build-up of a telephone connection gives out an identification and an alternate speech direction equipment in the emergency call subscriber set is subsequently switched to become effective through a control signal of the emergency call exchange, wherein its speech direction can be switched over through tone frequency switch-over control signals sent from the emergency call exchange, characterised thereby, that the identification is sent as continuous signal with the tone frequency or tone frequency combination differing from emergency call subscriber set to emergency call subscriber set until the alternate speech direction equipment is switched to become effective, that the alternate speech direction equipment is switched to become effective through the switch-over control signal first sent, that the alternate speech direction equipment is switched during the reception of the switch-over control signal to one of the possible speech directions and during the non-reception to the other speech direction, wherein a fixed association is predetermined, and that the release of the telephone connection is effected through a release command transmitted from the emergency call exchange to the emergency call subscriber set, wherein the emergency call subscriber set is set into the rest state through this release command.
