Patent DE-3039512-A1 (DE)
Inventor: SAUMWEBER ECKART DR ING
IPC: B60T8/34
Filed: 1980-10-20
Abstract: An anti-locking brake force regulating device for rail vehicles has a digital evaluation circuit which monitors the speed, acceleration and slip of at least one braked wheel and transmits braking instructions to a brake actuating element. The instructions include a rapid or slow increase or decrease of brake pressure or maintaining the brake pressure constant. In order to achieve a smooth control during a braking operation, the evaluation circuit is such that after instructing a rapid change of brake pressure in response to exceeding a predetermined threshold value a slow change of brake pressure in the same direction as the rapid change is instructed if the threshold value is again exceeded and the slow pressure change begins by a maintaining brake pressure constant phase. The slow or pulsed brake pressure change is preferably maintained for a fixed predetermined period of time.

Title: Electrochemical reference electrode
Inventor: MARSONER HERMANN DIPL ING
IPC: G01N27/401
Filed: 1981-01-08
Abstract: Electrochemical reference electrode for the potentiometric measurement of ion concentrations, consisting of an electrode body made of electrically insulating material, in which there is a cavity which via an orifice in the electrode body can be brought into contact with the sample to be examined and in which a reversible reference electrode of the second type, preferably of type Ag/AgCl is enclosed. The object of the invention is to provide a liquid bridge which has a low electrical junction resistance, permits the potential to be established rapidly and precludes mixing of electrolyte solution with the sample. Furthermore, an arrangement was required which is suitable, even for very small construction, for analysing micro-amounts of biological fluids. This object is achieved by the electrode body orifice, which leads to the sample, being sealed by a synthetic, hydrophilic, organic gel which contains an aqueous solution of a neutral salt or neutral salt mixture, and the cavity being wholly or partly filled by this salt solution and/or this gel. <IMAGE>

Title: Apparatus for the automatic stacking of blanks for ceramic tiles, especially roof tiles
Inventor: WIELIGMANN FRIEDRICH ING GRAD
IPC: B65G57/30
Filed: 1981-01-20
Abstract: In an apparatus for the automatic stacking of blanks for ceramic tiles, especially roof tiles, the tiles or roof tiles (1), lying flat on a feed conveyor (2), are conveyed into the region of a lifter (5). The lifter lifts off the roof tile from the feed conveyor and moves it into the region of vertically arranged gripper elements (7, 8) which are located opposite one another and which grip laterally, at opposite edges, the roof tiles lifted off from the feed conveyor by the lifter. The gripper elements consist of rotating endless bands (9, 10) which are each covered with a flexible plastic coating (11, 12). The bands are guided via deflecting rollers (13, 14 and 15, 16) the upper deflecting rollers (14, 16) of which are made movable. These deflecting rollers are assisted by springs (17, 18) which tension the bands tautly over the upper deflecting rollers. Laid behind each of the bands towards the inside of the apparatus is a supporting strip (19, 20), on which the bands are supported, so that an exact vertical guidance of the bands is guaranteed. The lower part (19a, 20a) and the upper part (19b, 20b) of the supporting strips are designed so as to be bendable or pivotable in the opposite direction to the bands or outwards. <IMAGE>

Title: Device for the full annealing of nonferrous material in strip form
Inventor: KYRIAKIS JOHN
IPC: C21D9/60
Filed: 1981-01-21
Abstract: A device for the full annealing of nonferrous material, such as copper or aluminium, in strip form is incorporated in such a way in a continuous drawing or rolling process that, following this process, the material is guided in such a way by means of two rotatable pulleys arranged a distance apart that the material undergoes heating to the temperature required for the full annealing of the strip of material due to the flux induced by an induction coil arranged between the two pulleys. In this arrangement, one of the two pulleys is provided with a pulley rim formed by two circumferential grooves and composed of an electrically conductive material in order in this way to achieve an electrical short-circuit between the strip of material fed to one circumferential groove and taken off via the other circumferential groove. The secondary winding decisive for the operation of the induction coil is thus provided by the strip of material itself, while its primary winding is connected to a variable mains supply. The two pulleys are furthermore incorporated in a system for the quenching of the fully annealed strip of material, this system comprising a quenching chamber and a replenishment tank, each containing a certain quantity of a fluid used for the quenching process, the two quantities being held at the same level. <IMAGE>

Patent DE-3139919-A1 (DE)
Title: High-speed coating appliance and painting aid
Inventor: MEIXNER KURT
IPC: B05B9/04
Filed: 1981-10-08
Abstract: The high-speed coater is notable for simplicity, including ease of handling, and the advantages obtained by the use of both hands. While the left hand constantly introduces the desired quantity of paint into the brush by pumping, the right hand can work on uninterrupted. There is no need to dip the brush into the paint pot. Paints of low viscosity, which can be mixed in the paint container or drawn from the original container by siphon, are particularly suitable. When the pump is moved, the paint is passed through the delivery tube directly into the brush and can immediately be continuously applied. The high-speed coating appliance helps to save time in decorating and maintenance work, and can be used anywhere, since no energy source whatever is required, even at a distance from the house, because it is easy to carry. The appliance can be economically produced and is suitable for house painters, farmers and house and garden owners.

Title: Lighting unit with an integrated loudspeaker system
Inventor: FINOCCHI FRANCO
IPC: F21V33/00
Filed: 1981-12-15
Abstract: The innovation relates to lamps which can simultaneously be used for other purposes as well. The lamps used for this purpose are chiefly commercially available lamps in the most manifold variations, for example, pendant, floor standard and table lamps. Loudspeakers were built into these lamps. The sound source (loudspeaker) is not visible from outside. This combination dispenses with conspicuous and also mostly disturbing loudspeakers in dwellings, lounges, restaurants etc. If a plurality of combinations are suspended or set up in a room, they can be connected to operate both in mono and in stereo. They can be controlled centrally or also decentrally. The electrical signal feed for the loudspeakers can be provided inconspicuously, in a manner similar to the power supply for the illumination. Electrical interference does not arise in this case.

Title: Scrubbing device, especially for the waste air from paint spray booths
Inventor: JAHN HELMUT
IPC: B05B14/468
Filed: 1981-12-28
Abstract: A scrubbing device for scrubbing particles out of gases, in particular out of the waste air from paint spray booths, has an elongate inlet opening, formed by baffle walls, for the gas to be purified and the scrubbing liquid, and a pool of scrubbing liquid located below. In order to effect a relatively small pressure drop of the air flow over the scrubbing device and hence to minimise the energy consumption and the evolution of noise, the scrubbing device is designed in such a way that, on one longitudinal side of the inlet opening, the baffle wall on that side extends at first downwards and then outwards and forms, with the surface of the pool of scrubbing liquid, a first gap of such a height that the gas flowing essentially horizontally has at that point the highest flow velocity within the scrubbing device, and that, downstream of the first gap and of the edge of this baffle wall, a first impingement surface is provided which extends upwards from the pool of scrubbing liquid and, together with a second impingement surface arranged above and extending transversely to the first impingement surface, forms a second gap at the top.

Title: Process for desulphurisation of flue gases from a solids incineration plant and device for carrying out the process
Inventor: THUEMMLER SIEGFRIED
IPC: B01D53/00
Filed: 1982-02-12
Abstract: To desulphurise the flue gases from a solids incineration plant, it is proposed to cool the flue gases below the dew point prior to entry into the stack (16) and to collect the sulphur-containing condensate which forms and desulphurise it by passing it through an ion exchanger (12). The cooled flue gas themselves are expelled through the stack by means of a ventilator (15) or the like. The waste gas tubes (5) of the boiler (1) are led into a collection chamber (6) from which the flue pipe (14), with the ventilator arranged therein, is led to the stack (16). Condensate precipitating in the collection chamber (6) is taken up in a condensate collection chamber (7) and is introduced by a pump (10) via a hose piece (11) into the ion exchanger (12). The sulphur-containing condensate is there desulphurised and the desulphurised liquid can be discharged via an outlet hose (13) into the sewage system. <IMAGE>
