Title: Prefabricated lattice fence elements connection - involves plug coupling in end holes in interfacing channelled bars with stops
Inventor: ZAPF JUERGEN
IPC: E04H17/14
Filed: 1978-12-20
Abstract: Lengthways bars with a gutter-shaped profile are interconnected by cross bars to make up prefabricated lattice elements for a fence. The channels in the lengthways bars (3) face the cross bars (4), with an open end plug in the openings (5) formed. There is a plug element (6) for each pair of openings in adjacent elements (1, 2) for plugging with one end into each opening. Each plug coupling element is fitted with a stop (7) which limits the depth of insertion. Connection of lattice elements is simple and inexpensive, and stability is enhanced, while unwarranted dismantling is difficult.

Title: Mixing appts. for gases, vapours or liquids - where appts. is designed to minimise thermal stresses caused by the different temps. of the constituents being mixed
Inventor: STEEGMANNS GEORG
IPC: F22G5/12
Filed: 1979-02-27
Abstract: The appts. consists of a mixing tube (I), which is joined by connectors to both an inlet for one fluid and an exit for the mixt. On the outside of tube is a concentric tube (II) forming a ring chamber. The wall of tube (II) has a radial hole forming a ring gap round a radial inlet pipe for a second fluid. The second fluid flows along chamber and then through holes into tube (I); but a part of this fluid also flows via the ring gap into an outer ring chamber located concentrically round tube (II) and formed by an outer casing. The appts. is intended esp. for mixing fluids which have very different temps., so thermal stresses at the radial inlet are minimised.

Title: Transferring metal powder compacts from press to sintering trays - where die filling shuttle pushes compacts onto conveyor belt fitted with magnetic hoist loading compacts onto trays
Inventor: LOMBERG ALFONS
IPC: B22F3/00
Filed: 1979-03-28
Abstract: Reciprocating die filling shoe or shuttle has a hinged extension arm pushing the compacts onto a conveyor belt (I), which is driven stepwise and synchronised with the operation of the press. When a prescribed length of belt (I) has been filled with the compacts, a magnetic hoist or pusher lifts all the compacts and transfers them to a sintering tray located on another conveyor belt (II), which is located below and at 90 degrees to belt (I). Each longitudinal stroke of the magnetic hoist is pref. followed by the stepwise movement of belt (II), a counter pref. synchronises all the movements, and the overall result is that the compacts can be loaded in specific patterns on the sintering trays without using manual labour.

Abstract: A contrast correction signal is generated to compensate for the limited contrast range of known image converters. The one of the primary color signals having the highest luminosity is low-pass filtered, its amplitude indicative of darker picture portions boosted, by use of a nonlinear amplifier, the resultant signal is subtracted from a blanking signal which has been subjected to the same nonlinear amplification and the resultant difference signal is multiplied by the composite television signal. The multiplier output constitutes the correction signal which is added to the composite color television signal. The method and system are illustrated with respect to the PAL, NTSC and SECAM systems.

Title: Infinitely variable mechanical speed change transmission - incorporates crankpin with eccentric drive to control alternately operated clutches to rotate output spindle
Inventor: SCHILLER JOHANNES
IPC: F16H29/20
Filed: 1979-09-13
Abstract: The drive for a changeover mechanism which operates in a stepless mabber. It has a crankpin steplessly adjusted in an eccentric radius forming an output. This is connected to a moving member, so as to travel in a complete circle and drive a toothed member to rotate a gearwheel.

Title: Ozone generator operating by electrical discharge - has metal-coated dielectric serving as anode to add ozone to air passing to IC engine
Inventor: PRUSS GUENTER
IPC: F02B51/00
Filed: 1980-07-04
Abstract: An ozone generator (3) is located in the air inlet line (1) between the air drier (8) and the air filter (2). The inlet line has a spiral plate to cause eddying or turbulence in the incoming air. Alternatively, the ozone generator is connected to the air inlet line via a hole passing through their adjacent walls. The ozone generator consists of a stainless steep casing acting as cathode and enclosing a dielectric coated in metal acting as anode. The air gap between the dielectric and the casing forms the discharge space. Air is admitted radially into the discharge space and the ozone/air mix passes radially out of the space at the opposite end to the air inlet. Cooling air is allowed to flow axially through the generator. The ozone generator, the drier and the air filter may form a single unit. The advantage lies in greater efficiency through more complete combustion.
Patent DE-3027454-A1 (DE)
Inventor: MUELLER HANSJOERG
IPC: B01D21/00
Filed: 1980-07-19
Abstract: The device concerns a twin-settling basin consisting of two funnel-shaped settling basins, of which one is arranged inside the other. Each of the two settling basins is intended to receive solids particles of different size ranges. The outer settling basin has, at its upper end, feed means (1, 2, 3) for the liquid to be treated, which means also contain flow deceleration means (2, 3). The solids-laden liquid first passes through the outer settling basin, where the coarser contaminant fractions are separated out. Via further flow deceleration means (6), the liquid then enters the inner settling basin in which the finer solids particles are precipitated. The solids particles separated off from the liquid are discharged via pipes (11, 12) which are connected to the bottom of the settling basins and whose shut-off devices are controlled in accordance with the respective level of the solids particles in the two settling basins and with the filling level in the inner settling basin. The device is suitable both for the treatment of effluents of any types and for separating off solids formed in chemical precipitation processes, or for carrying out sedimentation processes of any type. <IMAGE>

Title: Non-contact inductive coupling circuit - has primary and secondary stages with band-pass filters for handling two-way transmissions of different frequencies
Inventor: ZIERHUT HERMANN DIPL ING
IPC: H04B5/00
Filed: 1980-08-04
Abstract: The non-contact inductive coupler is designed to allow information to be transmitted across a variable gap between two units. The primary unit has an oscillator (S) that is coupled to a band pass filter consisting of a capacitor (C1) and inductance (L1) that transmits a frequency (f1) signal across the gap to a secondary unit filter (C2,L2). The transmitted signal is rectified in a bridge circuit (B) and is amplified (V1). A second frequency (f2) signal is produced over a secondary unit filter (C3,L3) and this is received and is filtered (C4,L4) by the primary unit to control an amplifier (V3) coupled to the transmitting oscillator. The system operates in a self regulating mode to maintain operating voltages within the working range.
