Title: Sputtering with inhomogeneous magnetic field at cathode - using hot liq. cathode which can be replenished from a reservoir
Inventor: KAUSCHE HELMOLD DIPL PHYS
IPC: C23C14/34
Filed: 1975-06-24
Abstract: Process for depositing electrically-conducting films on a substrate comprises sputtering a cathode in a glow discharge between the cathode and an anode. The cathode contains at least one constituent of the film and is exposed to an inhomogeneous magnetic field. The novelty is that the cathode is located below the substrate and held at a temp. at which at least one of its constituents is liquid. With a multi-constituent cathode, esp. using two constituents, the constituent with the lower m.pt. is pref. liq. whereas the component with the highest m.pt. is solid. The pref. appts. includes a tank for holding the hot liq. cathode. Used for depositing films for liquid crystal displays; and Al foils and/or layers, esp. Al-Ta, with gas addns., for electric circuits. The magnetic field increases sputtering speed but causes non-uniform erosion of the cathode. By using a liq. cathode a constant surface height is obtd. for the cathode and localised sputtering presents no problem; moreover, the liq. is easily replaced.

Title: Hot sealing foil esp. for packaging - has plastic base layer and hot sealing layer extruded simultaneously
Inventor: GREINER EBERHARD
IPC: B29C48/10
Filed: 1975-06-25
Abstract: A hot-sealing plastic foil for packaging and similar purposes consists of a plastic base sheet and of a hot-sealing material applied directly onto this without any intermediate operations. The hot-sealing material is pref. a mixt. of a normally non-extrudable plastic and a synthetic wax. The material is useful e.g. as a lid, a skin-foil or as adhesive-free composite foil. For sealing to aluminium, paper, cardboard or any other common packaging material. The non-extrudable component of the hot-sealing material has a very low melting point, making it too thin for normal extrusion. If mixed with synthetic wax, however, it can be applied to the plastic base sheet during extrusion, thus producing the composite foil in a single operation.

Title: Roof snow load regulated thaw unit - has heater activated by switch operation dependent on weight measuring surface
Inventor: WOTSCHKE MICHAEL
IPC: E04H15/12
Filed: 1975-10-10
Abstract: The processs is for thawing out tent-type roofs, with regulation according to the snow loading. A heating appliance (9) is brought into operation by a switch (1) mounted under the roof (3). This makes contact, under snow loading, by weight metering surface. Under the effect of the heat given off by this, the snow is thawed and flows down as water until the remaining load on the roof is small enough for the heating appliance to be switched off, by virtue of the reduced effect on the weight metering surface. The appliance may be mounted under the roof, blowing out hot air by jets (12).
Patent DE-2546631-A1 (DE)
Title: Maintaining consistency of glue by adding water - using automation for precision to obtain perfect adhesion
Inventor: FONCK PIETER
IPC: C09H5/00
Filed: 1975-10-15
Abstract: The consistency of glue is maintained constant by automatically adding water according to the continuously measured viscosity of the glue maintained at constant temp. The appts. allow addn. of water via a valve which is actuated by the voltage level of a generator coupled to a motor which acts on the glue via an agitator mechanism. The viscosity is measured by a motor which is supplied with drive energy via a stabiliser and of which the shaft is connected in torque-transmitting relationship to the agitator and to the shaft of an electric generator at the output of which is an analyser. Below a given voltage level, the water valve is opened to reduce the viscosity and increase the voltage. As soon as the voltage reaches an upper limit the water valve is closed again.

Title: Binder resin coatings for anchoring (rough) dowels or studs - using filled coatings top coated with hardeners for high key strength
Inventor: BUCHHOLZ JOSEF
IPC: F16B12/24
Filed: 1976-01-09
Abstract: Securing steel dowels in assembled components incorporating aligned blind holes, where the roles are wetted with a binder resin, and the dowel is precoated with a mixt. of resin and filler. The resin based composition applied to the dowel is subsequently treated with a catalyst or accelerator to promote curing. pref. by spraying or dipping the surface of the coating just prior to inserting the dowel into its hole. Suitable for assembling components, of e.g concrete or wood, e.g for construction of chairs. The dowel may have a round or square cross-section, may be a straight rod or an angle pin, and pref. has a rough or ribbed surface. Also suitable for anchoring one end of threaded or partially threaded bars, i.e to provide anchorage studs in a concrete foundation. The resin enhances the keying of the dowel within its hole to resist disturbance by vibration etc. Use of a deep coating is said to be stronger than thin gum coatings. Application of hardeners to individual coated dowels avoids waste of resin due to pot life limits of premixed coating compsns. incorporating hardeners. Some of the surface hardeners are transferred to the coating resin already within the hole.

Patent DE-2608664-A1 (DE)
IPC: F04B9/04
Filed: 1976-03-03
Abstract: The unit serves in particular for dosing in liquids into a liquid stream. The displacers (1b, 2b) of at least two pumps (1, 2) operating in push-pull mode are driven by a control cam (3) in such a way that the opposite movements of the displacers in a start zone of the delivery stroke of the one pump and in an end zone of the delivery stroke of the other pump are superimposed on one another, and that the constant delivery rate of the two pumps resulting therefrom per angle of rotation corresponds to that delivery rate which is output per angle of rotation of the control cam by each individual pump in a delivery zone situated between the start and the end zones. As a result, the system is largely free of pressure surges, independent of the back-pressure. <IMAGE>

Patent DE-2630960-A1 (DE)
Title: Radiator heat output measurement - has bypass to run flowmeter impeller at min. revolutions sufficient to power thermal meter
Inventor: NIEDERMEIER HORST
IPC: G01K17/10
Filed: 1976-07-07
Abstract: The method for measuring thermal output from heating systems is designed to reduce metering error and to simplify the mechanism of the flowmeter and counter. To enable the impeller of the heat counter to run continuously at a predetermined basic speed when radiator valves are closed, a by-pass is fitted beyond the meter through which the heated medium, e.g. water, may flow. The flowmeter impeller will then run continuously and can provide a source of energy to run the actual thermal meter mechanism without the need for a separate power supply. As the calculated heat output is determined from flow rate and temp. difference, no additional error is introduced by the continuously running flowmeter since, with closed radiator valves, there is no temp. difference between flow and return pipes.
