Title: Converting linear to rotary motion - by using arrangement of axially projecting intermeshing teeth
Inventor: PLUECKHAHN SIEGFRIED
IPC: F16H25/12
Filed: 1990-03-30
Abstract: The device converts the axial movement of a first shaft into the rotary movement of a second shaft.  One end of the first shaft is fitted with a device which has two diametrically opposite teeth. Each tooth has one flank sloping at 45 deg. and the other flank sloping at 30 deg.  to the shaft axis.  The end of the second shaft is fitted with a similar device. The two shafts are axially aligned with each other with the teeth (1) of one device fitting into the gaps between the teeth (2) of the other device.  When the two surfaces which slope at 30 deg. are in contact with each other, the rotation of the second shaft for a given axial movement of the first shaft, is less than when the 45 deg. surfaces are in contact. USE - Mechanism is intended for the operation of air flow control valves.

Title: Compensating filter for ionising radiation detector -  is independent of energy and direction of radiation, produced at low cost
Inventor: MASSAG CHRISTOPH
IPC: G01T1/29
Filed: 1990-10-15
Abstract: Compensating filter arrangement for a tubular radiation detector, measuring ionising radiation, consists of a single cylindrical tube, surrounding the active vol. of the detector, with a length shorter than that of the active vol. Length, material and material thickness are chosen so that when radiation falls perpendicularly on the axis of symmetry, the ratio of masked to unmasked view of the active vol., because of absorption, produces independence of energy. The metal tube is open at both sides, increasing the projection of unmasked area when radiation falls at an angle. ADVANTAGE - Energy and directional independence at low cost.

Patent DE-4109744-A1 (DE)
Inventor: HUBER WERNER DR
IPC: B41F33/00
Filed: 1991-03-25
Abstract: The invention relates to a method and a device for the determination of area coincidence of a master to be printed, in particular a printing forme of a printing machine, preferably an offset printing machine, wherein the local remission of a measurement area recorded is determined by optical scanning of the master and the master has an inhomogeneity which is independent of the area coincidence, dependent on the location and influences the measurement result of the scanning. To reduce measurement errors, provision is made for the printing areas to have a different colour (colour difference) in relation to the non-printing areas of the master, for at least two remission values, which differ from one another in spectral terms in accordance with the colour difference, to be determined by each measurement area (12), and for the two remission values to be evaluated to separate a proportion of the measurement result influenced by the area coincidence (fD) from a proportion of the measurement result influenced by the inhomogeneity ( gamma ). <IMAGE>

Title: Exhaust gas washing - uses strong agitation of fluid with gas to collect toxic matter by transfer contact in sealed container
Inventor: KISS GUENTER H
IPC: B01D47/02
Filed: 1991-07-16
Abstract: The fluid washing action for exhaust gases, esp. for rubbish incinerators, has a container for the gas which is sealed against the ambient environment with a flow of low temp. fluid vols. The fluid is kept constantly on the move, through a stirrer. During agitation, the exhaust gas is kept to the condensation temps. and dewpoint of the heavy metals to be removed, and maintained until all the toxic matter has been sepd. from the strongly-moving fluid, which then has a content matter level which can be tolerated by the environment. The matter is taken up as an adsorbate, absorbate and/or in a finely dispersed microscopic form. The cleaned gas is taken from the fluid into the environment, while the fluid is passed through conventional separating and settling stages, and the cleaned fluid is returned for further use. ADVANTAGE - The method gives increased transfer contact between the soiled exhaust gas and the cleaning fluid, for an improved cleaning action

Inventor: KOENIG UDO DR RER NAT
IPC: C23C28/00
Filed: 1991-08-14
Abstract: In order to improve the wear resistance of tools with cutting edges made of cubic boron nitride (CBN) or polycrystalline cubic boron nitride (PCBN), it is proposed that the CBN or PCBN body be coated with a 0.5 to 6  mu m thick layer of one or more oxides of the metals zirconium and/or yttrium and/or magnesium and/or titanium and/or aluminium, preferably aluminium oxide. The wear-resistant coating is deposited from the gas phase at gas-phase temperatures of up to 800 DEG C.

Patent DE-4136699-A1 (DE)
Inventor: FERRERO LOUIS
IPC: C09K23/52
Filed: 1991-11-07
Abstract: The invention relates to a novel preparation process for stable complex multiple emulsions of the water-oil-water type, which are highly suitable for use in cosmetic preparations. The primary emulsions of the W/O type are prepared both in the presence of a non-ionic polymeric lipophilic emulsifier and of a non-ionic polymeric stabiliser, which in each case preferably have an HLB in the range from 6 to 10. In a second process step, further water, which contains a hydrophilic emulsifier having a relatively high HLB of preferably 12 to 25, is added to this primary emulsion until phase reversal occurs. It is important that in this second process step the process is not carried out in reverse, i.e. the primary emulsion is not added to the water phase. Further active substances, such as UV filters and vitamins, can be added to the aqueous or oily phase of the emulsions. In a third process step, hydrating agents and/or gelatinising agents can be added and as a result the viscosity can be increased without the stability of the multiple emulsions being impaired.
