Title: Wind-induced noise reduction for telescopic aerial - adding projections to prevent formation of cyclic wind eddies
Inventor: GOETZ HANS DIPL ING
IPC: H01Q1/00
Filed: 1978-10-25
Abstract: The telescopic aerial is for motor vehicles and has as its object the reduction of perceptible noise, due to wind oscillation inside the vehicle. The cylindrical basic aerial rod (1) forms part of a telescopic aerial assembly and is provided with projections or discontinuities in its smooth surface. These discontinuities may take the form of a spiral (2), short projections, axial flutes, or similar. The object is to prevent the formation of wind eddies at regular intervals which can generate a tone. The modified length of the aerial should extend from its root on the car body to at least roof height. The modified aerial rod may be formed by extrusion, or may be a fabrication with separate projections attached to a plain cylinder.

Title: Electronic ignition system with inductive proximity detector - operating in conjunction with cam lobes on distributor rotor to generate ignition timing impulses
Inventor: ANGER ALOIS
IPC: F02P7/067
Filed: 1979-04-30
Abstract: The proximity detector (9) is fitted on a carrier (24) inside the distributor housing (11). The cam on the distributor rotor is fitted with a cylindrical magnetic equivalent (12) of the cam lobes. This attachment is definitely registered with respect to the rotor in order to give the correct timing. As the rotor spins a square wave output is generated by the proximity detector (9) which is then used to control the ignition instant. The proximity detector carrier can be linked (23) to a pneumatic advance and retard bellows. By changing the angle of the detector face relative to the rotor radial axis, the ignition point can be moved. The proposed proximity detector and modified rotor end can be fitted as a replacement for the contact breaker assembly on some existing distributors.

Title: Sewing machine with alternately-operating twin needle-bars - producing decorative two-thread chain-stitch or three-thread lock-stitch seams
Inventor: GEORGIEV KIRIL ALEXANDROV
IPC: D05B73/00
Filed: 1979-05-23
Abstract: A decorative stitch is produced from two needle-threads which alternately form loops which interlace with each other on the underside of the fabric. The stitch exhibits a single straight line of thread on the face of the fabric, and alternating loops on the reverse. A mechanism for producing the stitch has two needle bars driven from a single mainshaft, whereby the needle bars are inclined towards each other along lines which intersect at a point on the surface of the stitch-plate above the axis of the looper. The seam incorporates two or more different threads in a variety of combinations, and can be produced by a comparatively simple and reliable mechanism which is capable of high productivity.
Patent DE-2929052-A1 (DE)

Title: Unloading ceramic tiles kiln car racks - using reciprocating rams pushing baked tiles sideways out of racks to form single row on conveyor belt (NL 3.9.80)
Inventor: KUIJPERS JOHANNES A
IPC: B65G59/12
Filed: 1980-02-23
Abstract: The storage racks have open sides and travel horizontally and stepwise past an ejector fitted with a horizontal row of vertical stacks of rams. The ejector is reciprocated transversely, so each ram enters a slot in a rack and drives a tile onto a conveyor belt. The rams in adjacent stacks are pref. located at different heights and used together with an inclined conveyor belt so only a single row of tiles is formed on the belt. The storage racks are located on a row of kiln cars, and the invention provides mechanical handling plant for the progressive and automatic unloading of the kiln cars, which travel stepwise along a track. The ram assembly is located on one side of the track, whereas the conveyor belt is located on the other side of the track.
Patent DE-3007295-A1 (DE)
Title: Demodulator for two data signals - has zero detector with two spacing converters, subtractor and accumulator for modulation at two frequencies
Inventor: PARRAS KARLHEINZ DIPL ING
IPC: H04L27/156
Filed: 1980-02-27
Abstract: The demodulator has a detector for detecting waveform passages through zero in a pulse sequence. The detector output is passed via a delay circuit to a spacing converter that produces a multi-bit signal describing a number depending on the delayed pulse sequence. The number describes the inverse of the frequency of the received signal. The pulse sequence is passed to a second spacing converter. The multi-bit signals from both converters are added in a subtractor to give a difference. An accumulator produces the average of the multi-bit signals over a given time and passes it to a comparator. The frequency of the demodulated signals is determined by exceeding or falling below a selectab threshold signal.

Title: Seal welding machine for plastics multicompartment packages - has removable frames fitted to welding plate for various patterns of containers
Inventor: MEYER KLAUS
IPC: B65B51/12
Filed: 1980-03-26
Abstract: Welding station for packaging machines is intended esp. for seal-welding covering foil onto multi-compartment, moulded lower containers. The welding machine comprises an upper part containing a heatable welding frame and a lower part containing the abutment; the two parts can be brought together or moved apart after welding. Specifically, the welding plate fixed to the lower part (and/or upper part) of the housing has fixing means enabling a spectacle frame to be detachably fitted into it. This spectacle frame has the necessary welding and/or abutment surfaces for the pattern of welding seams to be produced for the particular packages being processed. In the lower part of the welding machine the spectacle frame has a peripheral welding rubber strip. For the seal-welding of plastics foil onto lower containers, where the pattern of the container assemblies frequently needs to be changed. The removable spectacle frame is comparatively light and can be replaced by another of different form for each change in the form of the packages. In this way the need to remove the heavy welding abutment frame from the lower part of the welding machine is eliminated while at the same time the previous method of laying replaceable bars and rubber strips across this heavy frame is eliminated, together with the attendant time-consuming work.

Title: Static converter for speed control of asynchronous motor - has regulator circuit forming separate commands for real and wattless current components
Inventor: PUTZ ULRICH DR ING
IPC: H02P27/04
Filed: 1980-05-30
Abstract: A converter-controlled asynchronous motor operates over a wide speed range with forced and machine fed commutation. The converter and its control system operate without a feedback signal from the motor rotor. In order to define the operating point of the motor the significant components of the machine circle diagram are used. The magnetising current component is set by the voltage regulator in the control system, and the active, torque producing component by the frequency or speed regulator. These components are added geometrically and applied to the current regulator. In addition, the phase shift between voltage and current is evaluated from the two components and used in the control circuit for the machine-commutated inverter.

Title: Ore dressing grinding circuit - passes underflow of cyclone classifier to water-only cyclone for power savings
Inventor: KELLERWESSEL HANS DR ING
IPC: B03B9/00
Filed: 1980-10-24
Abstract: Device to segregate or separate fine-grained materials of high density from the accessory constituents, specially from finely ground particles of high density on the recirculated classified material of grinding circuits of ores, uses in addition to the conventional hydrocyclone classifier a water-only cyclone with a flat bottom. The latter processes the underflow of the hydrocyclone classifier which has usually a very high solids content. Its own underflow is passed to the flotation department, while its overflow is recycled to the mill feed. This saves power for the repeated grinding of fine-grained material.
