Patent DE-2935457-A1 (DE)
Title: Colour shade exposing from eight basic colours - using transparent covers on covered original and forming raster elements of overlapping or covering shape
Inventor: KUEPPERS HARALD
IPC: B44D3/00
Filed: 1979-09-01
Abstract: The eight basic colours used contain white, yellow, orange red, magenta, violet blue, cyan, green and black. The colour transition values in each colour shade are formed as a proportion related to white and black. On a covering document are inserted transparent coatings and the shade evaluation stages are formed by raster elements, which may be transparent or opaque. The shade evaluation stages may be formed not by rastering but by overlapping half-tones. If the originals are trans transparent and in yellow, magenta, and cyan the transparent covers are organe red, green and violet blue. White covers are not necessary, as the transparent white light is proportionally effective. The exposed colour shades are determined by the results of the used shade evaluation stages. From the originals and covers can be formed a code for each colour shade, with precise characteristic.

Title: Automatic noise slicing for pulse modulated light receiver - uses comparator with reference set by mean signal level and pulse component fed by capacitor to amplifier
Inventor: GRIESE HANS-JOACHIM DR ING
IPC: H04B10/60
Filed: 1979-09-14
Abstract: Information transmission by pulse modulated light, e.g. infra-red, is received by ohoto-diodes (7). Their load consists of two resistors in series (8,12). One (8) is shunted by an inductor (9) and the pulse component of diode outout appears across it. The other (12) is shunted by a capacitor (13) and the 05 component appears across it. Since the mark/soace ratio of the transmission is typically 1:50 the DC component is mainly due to noise. The pulse comoonent is fed via a capacitor (10) to an amplifier (11). The amplifier outout is fed to a comparator (14) with the DC component as its reference input. The comparator output is the pulses with their base levels sliced off above the mean noise level. The slicing level is self-adjusting for varying noise level.

Title: IR beams across waterway identify passing ships - by comparing hull and superstructure signatures with stored data from which irrelevant detail is suppressed
Inventor: KAEHLER HELMUTH DR RER NAT
IPC: G01V8/20
Filed: 1979-10-05
Abstract: Ships moving along a waterway interrupt a pattern of IR light beams. Two beams, spaced along the waterway and close to water level, are interrupted by the hull. Their outputs are used for computing speed, direction and overall length. Two pairs of beams, at different heights in a vertical plane, are interrupted by the superstructure. Their outputs are processed to suppress irrelevant detail and converted to two frequency/length signature codes which represent superstructure outline, by combining beam outputs with speed and length data. The ship is identified by comparing length and the two signatures with stored data for all known ships, and selecting the one which gives the best fit. More than one set of data may be stored for each ship, to allow for tides and loading of the ship.

Title: High-speed economy helicopter - has fixed wings for high-speed lift, propellers for high-speed thrust, and rotor idling with blades in neutral pitch
Inventor: ROUSSEAU PETER DIPL PHYS
IPC: B64C27/04
Filed: 1980-03-22
Abstract: The high-speed, high-economy helicopter has a streamlined fuselage with variable-incidence stub-wings adequate for the full lift requirement at higher-than-cruising speeds. The rotor then continues to turn slowly, its blades automatically held in the plane of rotation. Contrarotating propellers at the wingtips at high speed operate - high efficiently since they can be specially designed for these conditions - with loads differing only by the torque due to rotor rotation. During vertical ascent one only operates, at low load to balance the lift reaction torque.

Title: Boiler for water heater - has jacket and return water passes along outside wall, mixes with heater water
Inventor: SEIDL FRANZ DIPL ING
IPC: F24H1/28
Filed: 1980-04-22
Abstract: The horizontal boiler has a deflection chamber for fluid or vapour fluids. It has a combustion chamber, concentrically surrounded by a water jacket, and feed- and return-pipes, being located close to or concentrically within each other. The pipes are formed, so that at least a partial mixing of the return water with the already heated boiler water, takes place in the warmest area of the boiler. The feed- and/or the return have associated elements within the boiler. These permit a return inlet, e.g the colder return water is guided along the outer wall of the boiler. An opposite flow results within the water jacket to the warmer water, on the inner wall of the boiler, which faces the combustion chamber.

Title: IC engine afterburner with igniter and thermal recycling - has catalytic oxidation stage added at end of line, operating in conjunction with existing equipment
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N3/26
Filed: 1980-11-29
Abstract: The IC engine exhaust gas afterburner is based on known practice with an igniter. There is thermal recycling - primarily by counterflow - between incoming raw gas and outgoing afterburner exhaust, and various possibilities for increasing heat exchange. A catalytic-oxidation stage is introduced at the end of that exhaust line, its life lengthened not only conventionally, e.g. by vibration damping suspension, but also by immediate direct combustion in the afterburner of the large amounts of contaminants associated with cold starts. Once the entire system has reached a predetermined steady state thermally, gas treatment - by afterburning, catalytic oxidation or a harmonised combination of both - is determined by gas quality.
Patent DE-3106487-A1 (DE)
Title: Drilling and percussion hammer
Inventor: BLEICHER MANFRED
IPC: B25D16/00
Filed: 1981-02-21
Abstract: The drilling or percussion hammer has a percussion mechanism (813) with a drive piston (821) which accelerates a striker (823) via an air cushion (822). The striker (823) strikes a tool (819). The drive piston (821) is moved in a reciprocating manner by means of a rotating drive sleeve (828) which is aligned coaxially with the drive piston (821) and has fitted tubular parts (828', 828'') which are provided with guide surfaces (830', 830'') running in curves. The guide surfaces (830', 830'') enclose a driving dog which acts on the drive piston (821) and is designed in the form of a ball (831) to avoid wear. The guide surfaces (830', 830'') on the individual parts (828', 828''), as long as these parts are not yet fitted into the percussion mechanism, are readily accessible and can therefore be produced quickly in a technically simple manner. The drive piston (821) is secured against rotation in a low-wear manner by means of additional rollers (852) which are movable in guide slots (836, 837) essentially in the longitudinal direction of the drive piston. <IMAGE>

Title: Arrangement for measuring the RMS value, the arithmetic mean value or the peak value of electrical signals
Inventor: BAGER RALF JOACHIM DIPL ING
IPC: G01R19/04
Filed: 1981-04-23
Abstract: It is known that there are integrated circuits such as IC AD 536 for measuring the RMS value of electrical signals. The essential feature of the invention consists in virtually making the averaging time constant of such RMS meters zero so that this meter takes over the function of a full-wave rectifier which is needed for measuring the arithmetic mean value and the peak value. Thus, an extremely inexpensive measuring rectifier which operates accurately in the low-frequency region and allows alternating voltages to be measured in accordance with all conventional methods is obtained by clever arrangement of the individual function blocks by single-pole switch-over of the capacitor according to the drawing. If no use is made of the possibility of measuring the peak value, the additional circuitry costs almost nothing. <IMAGE>

Title: Ammonia-free electroless nickel-plating bath and method for nickel-plating dielectrics
Inventor: YARKOSKY EUGENE F
IPC: C23C18/36
Filed: 1981-08-07
Abstract: An ammonia-free, electroless nickel-plating bath is proposed which has a high tolerance to the presence of palladium(II) ions. The bath consists of an aqueous solution which contains approximately from 0.025 to 0.2 mol/l of nickel ions, approximately from 0.1 to 0.5 mol/ l of hypophosphite ions, a non-amine, ammonia-free chelating agent (chelatant) for nickel ions in excess of the stoichiometric amount required for complexing the nickel ions, and a soluble amine in an amount which results in complexing of palladium(II) ions without significantly reducing the nickel deposition rate. In addition, an improved method for electroless nickel-plating of a dielectric (insulator, non-conductor) is proposed, which employs the bath according to the invention. Preferred non-amine, ammonia-free chelating agents are carboxylic acids and their salts, which can form a nickel complex having a Kf above approximately 10<2>. Said amines are able to form a palladium/amine complex with a Kf which is numerically greater than the Kf of the non-amine, ammonia-free chelatant/nickel complex. Examples for amines are ethylenediamine, triethanolamine, monoethanolamine and diethylenetriamine.

Title: Device for the comparative display of the consumption of heating energy in the previous year with the consumption of heating energy in the current year
Inventor: VOELKER KARL
IPC: G01K17/06
Filed: 1981-09-14
Abstract: The invention relates to a device for the comparative display of the consumption of heating energy in the previous year with the consumption of heating energy in the current year on heating cost allocators which can be mounted on heaters (radiators) and are based on an electrical determination of consumption or on measurement using the principle of evaporation with the aid of measuring ampoules. Arranged inside the heating cost is a pointer or a mark allocator which are arranged capable of displacement along a scale or along an ampoule. The consumption can be adjusted and read off by means of this display of the preceding year in evaporation devices. In the case of heating costs distributors with electrical detection of heat, the display of the previous year also serves for measuring the consumption tendency in addition to the measurement of consumption. <IMAGE>
