Patent DE-3629706-A1 (DE)
Title: Method for coding and transmitting analog information
Inventor: DIRR JOSEF DIPL ING
IPC: H04B3/38
Filed: 1986-09-01
Abstract: In the main application, multi-valued coding is effected in such a manner that sums of phase changes of periods of different magnitude, and their direction, a number of periods of only one alternating current of different magnitude, and the amplitude magnitudes, are provided as code element steps. Transmission is based on angle and pulse modulation. The invention reduces the bandwidth even further by basing the transmission on single-sideband amplitude modulation. The reliability of frequency modulation can be achieved, for example, if the amplitude magnitudes are avoided as coding means so that the amplitudes of the alternating coding current are always of the same magnitude. In addition, the advantages of pulse code modulation can be obtained if the amplitude magnitudes are only used in 2 or 3 steps.

Title: Electrical switch
Inventor: ZIEBARTH WALDEMAR
IPC: H01H13/20
Filed: 1986-09-04
Abstract: An electrical switch is proposed whose electrical switching contacts can be influenced by means of an operating element, via a switching piece. The operating element is in this case mounted displaceably on the insulating material housing and the switching piece is mounted on the insulating material housing such that it can rotate. A component which is supported in a sprung manner on either the switching piece or the operating element and is assigned to a profile track provided in the operating element or switching piece respectively is arranged between said switching piece and operating element in order that the operating element describes an operating path which is independent of the path which the switching piece must travel in order to cause the contact parts to switch over and for the purpose of the operating element additionally returning automatically from the switching positions to its quiescent position after being released or automatically assuming its quiescent position after any existing latching is released. The effective length of the path travelled by the component on the profile track is limited to the intended free play (idle path) by means which are provided on at least one of the two parts.

Title: Trickle-film reactor, without a nozzle plate, for the continuous elimination of dissolved water constituents
Inventor: ADAM MATTHIAS DIPL BIOL
IPC: C02F3/10
Filed: 1986-09-19
Abstract: The invention relates to a trickle-film reactor, without a nozzle plate, for the continuous elimination of dissolved constituents from waters which are very largely free from suspended matter, such as ground water, by predominantly oxidative processes. The aim of the invention is the creation of a treatment plant for newly built plants and for the reconstruction of existing plants which are not suitable for complete retention of water. Reliable and low-maintenance water treatment is to be made possible. The object underlying the invention is to develop a continuous trickle-film reactor, without a nozzle plate, which reactor combines the advantages of a dry filter stage, wet filter stage and sedimentation stage. According to the invention, free-floating packing material having a density substantially less than 1 g/cm<3>, preferably foamed polystyrene balls, is provided in the open reactor, together with a retention depth regulator having a vent orifice. Additional aeration is performed predominantly in the wet filter zone. A guard over the pure water outlet from the sedimentation zone reduces the discharge of sink materials.

Abstract: In a circuit arrangement for processing a video signal containing horizontal and vertical synchronisation pulses and having a counting device (4) which passes through cycles and is clocked in dependence on the horizontal synchronisation pulses and in which one cycle corresponds to a standard ratio of the frequencies between the horizontal and vertical synchronisation pulses, an evaluating arrangement (22) which detects the phase angle of the vertical synchronisation pulses with respect to control pulses output in each cycle by the counting device (4), and a change-over switch (24) which, controlled by the evaluating arrangement (22), derives a frame synchronising signal from the control pulses (indirect synchronisation) when the phase angle at least almost matches, and otherwise from the vertical synchronisation pulses (direct synchronisation), the disturbances are reduced and thus the picture display is improved by means of a divider (3) via which a number of selected vertical synchronisation pulses, which is reduced in accordance with its divider ratio, is supplied to the counting device (4) for transfer into an initial position, the phase angle only being detected when the selected vertical synchronisation pulses occur. <IMAGE>

Patent DE-3642340-A1 (DE)
Title: Cellar window in a solid frame
IPC: E06B5/06
Filed: 1986-12-11
Abstract: A steel frame (10) with Z-profile is cast in a solid frame (1) consisting of concrete. The cellar window frame (20) bears, on the outer side, on projecting flanges (12) of the steel frame. Fastened on the two vertical legs (21) of the cellar window frame are horizontal lugs (23) which can be plugged through slots (13) of the flanges. When, on plugging in, the window frame has reached its position, then latching takes place automatically by resilient tongues (24) which are integrally formed on the plugged-in part of the lugs. The connection between window frame and solid frame can thus be carried out simply and rapidly without tools. The lugs can be fitted both for steel window frames and plastic window frames. <IMAGE>

Patent DE-3724099-A1 (DE)
Title: Gas-foam scrubber
Inventor: GEIER-HENNINGER KURT
IPC: F23J15/04
Filed: 1987-07-21
Abstract: The use of a gas-foam scrubbing unit, because of the heat recovery potential, is not a continuing expense factor, but the investment cost of such a unit is paid back very rapidly. The hot vapours at 60-70@ which rise from the gas-foam scrubber have an air humidity of approximately 80%. This heat loss, calculated over the energy input, will then lie below 5%. The correct design of the pipe cross-sections, the water flow rate in the gas-foam scrubber and also the foam surface area with air outlet for the purified exhaust gases are decisive. Feeding water in order to replace loss by evaporation is not critical. The pH meter and the water circulation carry the pilot function in order that lye and foam-forming fluid are always present in the vessels. Monitoring must be carried out at certain intervals. The container, gas-foam scrubber, must be fabricated from stainless steel, likewise the piping and circulation pump and also the emergency cooling in the water supply area. The gas-foam scrubber is a contribution to keeping the air clean, and one side effect is that it is also a silencer for loud gas exhausts. <IMAGE>

Abstract: The invention relates to a wheel set guide means for bogies of rail vehicles, in particular short-distance vehicles. 
<??>In such vehicles, a continuous floor at as low a level as possible is desired.

One of the wheel sets is driveable, the movable wheels being connected in a torsion-proof manner by means of gear means so that in terms of running technology the same effect is achieved as if the driven wheel set were connected to a rigid wheel set shaft without, however, said shaft being in the way of the floor so that a vehicle equipped with these bogies can have a continuous floor at a low level.
