Title: Concrete interconnecting ring for forming walls, and wall formed from interconnecting rings
Inventor: EHL BERNHARD
IPC: E01F8/02
Filed: 1988-10-01
Abstract: A concrete interconnecting ring having four side walls and, if appropriate, an insertable base slab is intended to be further developed such that walls of variable thickness and with freely selectable cultivation surfaces can be formed therefrom. Moreover, the intention is that said novel interconnecting ring can be easily combined with connecting rings of different forms. A connecting ring fulfils these requirements if a) the side walls (2, 3) run in an essentially rectilinear manner and form a rectangle, b) the length of the longer side wall (3) is approximately 1.5 times that of the shorter side wall (2), c) all the side walls (2, 3) exhibit a uniformly repeating interconnecting structure on their outer surface, and d) the interconnecting-structure elements occur at least four times on the shorter side walls (2). The design possibilities can be improved still further if further connecting rings of different forms can be combined with the abovementioned connecting ring, in particular connecting rings in the case of which all the side walls correspond to the shorter side walls (2) and together form a square. Usage lies predominantly in horticulture and agriculture. <IMAGE>

IPC: F02M35/12
Filed: 1988-10-24
Abstract: In a known air intake device, intake noise dampers are provided in series in the air intake pipe, especially in the region of the air filter. The construction is comparatively bulky and expensive as regards assembly. According to the invention, the intake tube (3) of the air intake device (1) is simultaneously designed as a noise damper and arranged directly behind the driver's cab. In this arrangement, various noise- damping elements (known per se) are combined and arranged in the region of the bend of the tube in such a way that they use the available space optimally for noise damping both in terms of space and in terms of their effect. <IMAGE>

Title: Circuit arrangement for signalling an operational state of a washing machine
Inventor: DIRR JOSEF DIPL ING
IPC: D06F34/28
Filed: 1989-02-22
Abstract: A monitoring device for household appliances is known (German Offenlegungsschrift 3404211 A1), in which control devices are provided for observing the operational state, irrespective of the location of the latter, the said control devices converting the respective operational state into encoded electric signals. Decoding devices, which control corresponding optical and/or acoustic display devices, are in the receiver, which has a mains connecting lead. In the case of washing machines it is especially important to signal the end of the washing process. The devices for this are naturally intended to be very cheap, that is to say "the soup should not cost more than the fish". According to the invention, large expenditure is avoided by providing, in the washing machine, a switching means which marks the end of the washing process and which subsequently applies a continuous or intermittent high-frequency alternating current in the region of 30-146 KHz to an existing low-voltage lead. In the receiving location, which is connected to a socket of the low-voltage supply, there are simple evaluation means with which this operational state is signalled acoustically and/or optically.

Title: Process for decontaminating soils which are contaminated with hydrophobic organic substances
Inventor: WESSLING ERWIN DR RER NAT
IPC: B09C1/10
Filed: 1989-02-25
Abstract: When soils which are contaminated with hydrophobic organic substances of low volatility are decontaminated, an insufficient or excessive amount of ozone is frequently used. It is an object of the invention to allow the ozone added to be metered. This object is achieved by adding ozone as a function of the specific properties of the soil, only such an amount of ozone being added that the soil contaminants can be converted by oxidation into products which can readily be subjected to microbial biodegration without unduly decimating the number of microbially active organisms. The process is particularly suitable for contaminated soils.

IPC: H03G11/04
Filed: 1989-06-09
Abstract: The signal voltage is applied to a high-ohmic load, such as an amplifier input, via a coupling capacitor as a.c. coupling.  The signal voltage is compared with two voltage  thresholds, defining a voltage window.  When the signal voltage lies outside the voltage window, a shifting current is fed to the capacitor via a load-side circuit node, with the current shifting the signal voltage back into the voltage window. Pref. the shifting current is approx. constant and is oppositely polarised for exceeding or non-reaching the both different voltage thresholds.  Typically two comparators (K1,2) are used in a specified circuit arrangement w.r.t. the circuit node (A). ADVANTAGE - Facility for evaluating lowest signal portions even with level limiting of a signal voltage.
