Title: Prepn. of liq. fuel mixts. with increased energy yield on combustion - by heating mixts. of oil, carbon and water
Inventor: LEE SOO B
IPC: C10L1/32
Filed: 1978-02-15
Abstract: Mixts. of carbon, oil and water are heated in a container open to the atmos. to 50-100 degrees C, the heating interrupted and 20-60 wt.% light oil added to the remaining liquid of the inhomogeneous mixt. to form a single liquid phase. This is separated from the carbon and briefly ignited before extinguishing by shutting off the oxygen supply. The liq. obtd. can be used directly as a liq. fuel for heating, power generation, etc., or mixed with oil and water to form a homogeneous liq. fuel. Heat content per unit wt. of the oil/water mixt. is almost equal to that of oil alone and substantially higher than that calculated from the oil content alone.

Title: Material strip tension monitoring system - keeps chamber volume constant in pneumatic ram of jockey roller
Inventor: FELLER ROBERTO
IPC: B65H23/188
Filed: 1978-02-20
Abstract: The system which monitors the tension in a strip of material when winding or unwinding, has a jockey roller swinging under the action of a pneumatic ram. The reaction point of the pneumatic piston follows the oscillations of the jockey roller keeping the volume of the pressure chamber at the piston crown constant. The ram cylinder can also follow the piston so as to keep the pressure constant. There can be a copying mechanism with a valve controlling a hydraulic ram. This in turn controls the pneumatic cylinder. The valve can be arranged to control the pneumatic system so that if the material should tear the jockey roller reaches the end position with constant speed as determined by the hydraulic flow.

Title: Distance and speed measurement system - uses coil near metal body with cut=outs causing oscillator output amplitude modulation
Inventor: SCHNAIBEL EBERHARD DIPL ING
IPC: H03K17/97
Filed: 1978-07-19
Abstract: A distance and speed measurement device has a metallic body with cutouts corresp. to incremental distances. There is a coil near the cutouts periodically affecting the operation of an oscillator, and an evaluation circuit responding to variations in oscillator operation. The operation of the device is not dependant on the coil separation distance from the metallic body or the length of cable between the coil and the oscillator circuit. The oscillator feedback gain is high enough to prevent coil parameter variations from stopping the oscillations. The oscillator output signal is amplitude modulated by the coil.

Title: Hood type hair dryer with motor driven blower - has heating element in hood jacket preventing overheating
Inventor: MOELLER HEINRICH
IPC: A45D20/18
Filed: 1978-08-08
Abstract: Hot air inside the hood (2) is eriven by a motor-driven blower. The actual heating foil (6) is set in the jacket face of the hood (2). A very large heating surface is thus provided for the heat exchange between the air and heating element so that the temp. of the latter need not be so high as that of a heating element set directly behind the blower. Even if the dryer becomes defective and the air flow becomes uneven overheating does not occur.

Patent DE-2855393-A1 (DE)
Inventor: SCHELL LONI DIPL CHEM
IPC: G03C1/72
Filed: 1978-12-21
Abstract: A process for the preparation of planographic printing forms is described, in which a light-sensitive material composed of a support having a hydrophilic surface and of a light-sensitive layer, which contains a 1,2-naphthoquinone-diazide, is exposed imagewise, developed and then heated to a temperature above 180 DEG  C. for such a time and at such a temperature level that an oleophilic precipitate is formed on the hydrophilic image background, and the precipitate is then removed by treatment, for example wiping over, with an aqueous solution of about 0.01 to 50% by weight of polyvinyl phosphonic acid. The treatment has the advantage that in this case the support surface, for example anodically produced aluminum oxide, is not significantly attacked and is nevertheless completely freed from impurities.

Filed: 1979-05-25
Abstract: Directable mast arrangements are frequently used for overcoming obstructions on the terrain and for reducing disruptive ground reflections, etc., for the purpose of radio determination, Ordnance Surveying by means of radar or laser units, etc. A mast comprising tube elements which can be fitted together and have high torsional rigidity is mounted at its end, by means of its spherical mast foot (23), in a socket of a mast bearing (35) such that it can swivel by an angle @ to the vertical (z) within a conical casing. A cutout (36) in the mast bearing (35) produces an enlargement on one side of the conical casing and thus diverse possible applications of the mast arrangement, even for use in the open countryside. By constructing the mast bearing (35) on a base slab (B) with four vertically adjustable and angularly adjustable extension arms (7) fitted on the edge side, weatherproof mast arrangements, with or without ground anchoring, may be set up on virtually any terrain. <IMAGE>

Title: Corrosion resistant copper alloys - contg. nickel, aluminium, iron and manganese
Inventor: POPPLEWELL JAMES M
IPC: C22C9/06
Filed: 1979-06-05
Abstract: Corrosion-resistant, single phase copper alloy is comprised of 3.0-7.5% Ni, 1.0-4.0% Al, up to 3.0% Fe, 0.001-1.0% Mn and remainder Cu. The alloy may also contain up to 1.0% Cr and opt. up to 3.0% Co such that the total content of Fe+Co =4.0%.

They are relatively cheap and have good initial corrosion resistance, so that they do not release Cu into the environments or e.g. into drinking water like prior art alloys. They are esp. useful in the prodn. of pipes for use in heat exchangers, drinking water pipes, etc..
