Title: Foam suppressor for washing powder - produced by later addition of carrier material after prior agglomeration with part of carrier material
Inventor: PERNER JOHANNES DIPL CHEM DR
IPC: B01D19/04
Filed: 1980-04-05
Abstract: Prepn. of a low-melting foam suppressor in fine particulate form comprises spraying the foam suppressor melt onto fine particles of inert, inorganic support material 0.2-4 pts. wt. of foam suppressor melt and one pt. wt. of carrier material having a mean particle dia. less than 100 micron are used; the carrier particles are at a higher temp. than the m.pt. of the foam suppressor and spraying is carried out until the mixt. agglomerates to particles of dia. 100-1500 micron; there after 0.02-0.3 pts. fine particles having a softening point above the temp. of the mixt. are added and the mixt. is allowed to cool to below the melting temp. of the suppressor. Used as a foam suppressor for household washing powders where the basic anionic constituents tend to excessive foam prodn. Method enables a low-melting foam suppressor to be produced in a powdered form which has a long shelf life. The later addn. of the quantity of powder, which may be the same material as the original carrier material, results in stabilisation of the agglomerated material.

Title: Stress steel wire insertion rollers - have hydraulic stressing cylinder varying pressure dependent on motor torque
IPC: B65H51/10
Filed: 1980-06-10
Abstract: One or more pairs of motor-driven friction rollers are moved in relation to each other by a stressing element, to generate pressure between them and the length of prestressing steel wire running between them. The motor tongue is transmitted to the steel wire during inserting. The stressing unit, i.e. the upper part of a housing (2), is provided with an activating hydraulic cylinder (24) actuated by energy which varies according to motor tongue. The cylinder can have fluid connection to a motor connection (26) for hydraulic fluid. Thus a change in fluid pressure through the hydraulic motor (11) causes automatic adaptation of pressure generated by the cylinder. The roller slippage is reduced, without increasing the appliance size and weight.

Title: Circuit arrangement for subscriber stations in a telephone PABX system with a total of two subscriber stations
Inventor: HELSMORTEL LUC
IPC: H04M1/715
Filed: 1981-02-10
Abstract: The invention relates to a circuit arrangement for subscriber stations in a telephone PABX system with a total of two subscriber stations, both subscriber stations having exchange access and being able to connect to one another. The intended object of the invention is to implement this connection procedure at low cost. According to the figure, this is enabled in that, when the changeover contacts (k1 to k4) are actuated, the first subscriber station (T1) is disconnected from its own connection line (a1/b1) and the second subscriber station (T2) is simultaneously disconnected from its connection line (a2/b2) and connected to the connection line (a1/b1) of the first subscriber station (T1), in that, furthermore, a feed voltage supply (E2) can be connected between the speech wires (a2/b2) of the connection line of the second subscriber station (T2) and in that two changeover contacts (k5/k6) which, when actuated, connect the connection line of the second subscriber station (T2) to the exchange-side output (m/n) of the exchange circuit (AS) and disconnect the exchange circuit (AS) from the exchange line (m/n), are likewise disposed in the pair of wires (m/n), which lead to the exchange, of an exchange circuit (AS) used for an exchange connection. The advantage of the circuit arrangement according to the invention is that only one exchange set is now required and therefore also only one transformer is required and the call connection needs to be provided at only one point in the circuit arrangement. A feed voltage supply for ... connected via matching resistors and not via feed inductors. The invention can be used in every telephone system with two subscriber stations. <IMAGE>

Title: Self-cleaning shower head
Inventor: WAGNER FRITZ ING GRAD
IPC: B05B15/528
Filed: 1981-02-28
Abstract: In order to avoid encrustations, in particular lime deposits, in the region of the jet former, relatively thin-walled tubes (2) formed from flexible material are provided as jet outlet openings. The tubes (2) are configured such that, when the water supply is shut off (pressure-free state), they collapse or fold together and thus block off the jet outlet opening (3) to the atmosphere and so prevent drying, which leads to lime deposits from the water. If the water supply is opened, then the effect of the water pressure is to widen the respectively collapsed or folded-together tubes for operation and to form the jet outlet opening (3), as a result of which even different types of encrustations in this region, as early as their initial formation stages, are removed and flushed away. <IMAGE>

Title: Gun for inert-gas shielded welding
Inventor: OSSEGE JOHANNES
IPC: B23K9/29
Filed: 1981-06-11
Abstract: The invention relates to a gun for inert-gas shielded welding, whose nozzle-shaped mouthpiece has a longitudinal bore which is provided at the end with a widened area. The diameter of this widened area should be at least three times as great as, and the depth at least two to four times as great as, the diameter of the longitudinal bore. By virtue of this special design of the mouthpiece, on the one hand the guide of the welding wire is kept as narrow as possible in order to obtain a good current contact and to prevent an uncontrolled escape of the inert gas through the nozzle. On the other hand, by means of the widening of the nozzle according to the invention, a bonding of the welding wire and, consequently, an interruption of the welding procedure is completely ruled out. Welding sputter does not penetrate into the widened area and deposits on the edge of the nozzle tip. With such a nozzle tip according to the invention, a fault-free welding is possible without interruptions.
