Title: Mineral oil removal esp. from water surface - by binding with stearin, to form solid prod. in appts. comprising heated container, pressure and air sources, pump and spray device
Inventor: SCHULZ BRUNO
IPC: E02B15/04
Filed: 1990-04-20
Abstract: Mineral oil removal equipment consists of a heated container (1) for liquefying stearine; a pressure source, pref. a compressed air source (3) and a pump; and a spray device (7) connected to the container (1). A method of removing mineral oil (esp. liq. mineral oil prods.), by binding to form floating solids, involves spraying molten stearine (opt. mixed with vegetable oil) over the oil and collecting the resulting solids. USE/ADVANTAGE - The equipment is useful for removing mineral oil (prods.) from water surfaces. The stearine binds the oil to form a solid prod. which has stable floatability and is easy to collect. Uncollected residues are non-polluting and the stearine can be recovered by raffination or fractional distn. from the prod.

Abstract: The platforms 2 and 3 of the parking device are moved by scissor arrangements 6 and 23 respectively and by cylinder/piston arrangements 17 and 25 respectively. The cylinder/piston arrangements stand substantially perpendicularly to the orientation of the platforms and the scissor arrangements in the collapsed state. This enables the scissors to be brought close together and avoids dead centre positions and unfavourable lever arms. <IMAGE>

Title: Flexible composite superconductor for electric power cable - with spiral of ceramic superconductor in neutral zone of spiral corrugated metal tube core
Inventor: LEVACHER FRIEDRICH KARL DR
IPC: H01L39/14
Filed: 1990-05-14
Abstract: Flexible composite superconductor for electric cables consists of a superconducting, pref. high temp. superconducting ceramic material (I) and a metal substrate (II) of normal conductivity. (I) is in spiral form and wound around and attached firmly to a central cylinder of (II). The novel features are that (II) consists of a spirally corrugated tube (1) and (I) (3) is placed in the spiral, mechanically neutral zones of the corrugated tube, where it is connected electrically and bonded firmly to the (II) tube. USE/ADVANTAGE - The superconductor has the relatively large cross-section needed for cables and also satisfactory flexibility. If brittle (I) cracks, (II) provides a bridge preventing total failure of the superconductor. The (II) tube is also used for transporting the refrigerant (normally liquid N2 for high temp. (I)).

Patent DE-4021525-A1 (DE)
Inventor: SCHUSTER GEORG DIPL ING
IPC: C09K23/00
Filed: 1990-07-06
Abstract: The invention relates to aqueous solids suspensions which are stable to sedimentation and in particular milk of lime based on aqueous suspensions of calcium hydroxide Ca(OH)2, which contain, as sedimentation stabiliser, waterglass, preferably in an amount of 0.5 to 8% by weight, calculated as solid waterglass containing 17 to 20% by weight of water and based on the mass of the solid in the suspension, and processes for their preparation and their use and dry solids mixtures containing added stabilisers. In the case of the preparation of milk of lime, the waterglass may be added both before or during slaking of calcined lime and before or after calcium hydroxide is mixed into the preparation water. Suspensions stabilised according to the invention, such as milk of lime, are stable to sedimentation over a storage time of at least 5 weeks, even at low temperatures, not more than 5% of serum being formed. Even after a longer storage time without mechanical mixing, a corresponding milk of lime can be stirred up simply and rapidly for use. The invention accordingly has exceptional advantages in terms of process engineering and economics, since the investment costs for stirring or mixing apparatuses and mechanical mixing for stirring up are not required during the entire storage time. The invention leads in particular to high energy savings.

Title: Application of decorative surface(s) to substrate(s) - useful for car radiator emblems, etc. colours differing in reflected and transmitted light
Inventor: ITO TOSHIYASU
IPC: B44D5/00
Filed: 1991-02-28
Abstract: Decorative surfaces to substrates such as glass, resin, polymer, or metal.  Application of in chich, at least one decorative coating is sprayed on in an atmos. of Ar and O (O partial pressure 10-25%) which consists of partially oxidised Ti and/or Al. The reactive spray sources are Ti and A1 discs of high purity (99.999% each (5 and 6) which act as cathodes and are sepd. from the corresp. anode ring 88).  The cathodes are in the lower region of a cylindrical container (1), which has in its upper region the substrate (opaque or transparent) (11) fastened on to a clamping plate (10).  On the one side of (1) there are separated inlet ports to admit Ar and O (2 and 3), whilst on the other side there is an outlet pipe to discharge off-gases (4).  The gas pressure is held at a constant level (93 MPa) and a voltage is applied between (8) and (5+6) which gives rise to a glow-discharge.  This  creates Ar and o cations which bombared the A1 and Ti particles partially oxidising them during the spray process.  After a spray time of 30 mins. and a final gas vacuum of 4 MPa the decorative coating is complete.

Title: False twist airjet spinning device - has three stages to control the loose ends of fibre with a perforated funnel surrounded by a suction chamber in 1st section
Inventor: GOERLICH ROLAND DR
IPC: D01H1/115
Filed: 1991-05-25
Abstract: An airjet spinning device producing false twist yarn from sliver is placed between the drafting zone and the take-up rollers. The device is constructed in three sections, with a perforated funnel surrounded by a suction chamber in the first section. The sliver is brought through a drafting zone into the perforated passage which is surrounded by an evacuated chamber. The passage is funnel-shaped. The amt. of vacuum will control the number of loose ends which are drawn out of the sliver relative to the speed of falsetwist yarn being produced. An intermediary section also has a connection to the source of suction. This section is larger and is at the same deg. of vacuum as the outer chamber. These two may be connected by a series of slots or perforations in the division, in which case only one suction tube is required and the perforated passage is cylindrical. ADVANTAGE - The airjet is of economical construction. It controls a sufficiently large number of loose ends to fasciate the yarn.

Title: Sliver feed - has path deflection above cans to the drawing units to give a short path for fine sliver material
Inventor: STAHLECKER FRITZ
IPC: D01H9/00
Filed: 1991-08-20
Abstract: The sliver feed to the spinning stations of a ring spinner assembly has a powdered path deflection system closely above the sliver cans to take out the sliver. The sliver path deflection system lies generally on the same horizontal plane as the powered take-in rollers of the associated drawing unit for the spinning station. The sliver cans are supported by a platform above the base level of the ring spinners. The sliver cans have a max. outer dia. of 300mm. The powered take-in rollers of the drawing units are a max. 1.4m above the base of the ring spinners. The path deflection is a feed roller, or a deflection roller with a conveyor belt round it, with a horizontal belt path as far as the powered take-in rollers of the drawing units, and passing round the take-in roller to be powered by it. The conveyor belt has a shrouding against side air, as a sliding runner The belt deflection roller is on a frame which can swing upwards, and is part of the belt tensioning system. The take-in rollers of the drawing units are as close as possible to the rear side of the ring spinners, and the drawing units are pitched at a angle of 45 deg. to the horizontal. The take-in rollers can be disengaged from a drive shaft, and their pressure rollers are loose rollers of paired pressure rollers. A funnel, in front of the take-in rollers, lifts the sliver from the conveyor belt. The conveyor belt also works with a sliver deflector. The sliver cans are placed on a conveyor belt. A conditioning channel is at each sliver can location, in a conditioning tunnel covering the sliver cans (10) between adjacent ring spinners.

The inner rotating ring is supported on bearings and is moved using a vacuum force from a vacuum chamber (7) linked to the inlet manifold. ADVANTAGE - Improved engine efficiency over range of speeds/torque, simple adjustment to inlet manifold.

Title: Elastic roller for recoiling parallel bands - has several tensioned thin resilient rings on main shaft
Inventor: IMADA TOSHIO
IPC: B21B39/08
Filed: 1992-04-24
Abstract: The rings (10) are made of rubber-like material and placed on behind the other on the main shaft. They are tensioned from both sides and are fixed as one unit.
