Title: Jam-proof actuator structure - has segmented flanges which fracture in response to forces applied by engagement of deformation
Inventor: RUNKEL MANFRED ANDREAS
IPC: F15B15/14
Filed: 1978-07-21
Abstract: An actuator continues to operate after deformation of a portion which would normally restrict movement between the piston and cylinder of the actuator. The piston or gland of the actuator is constructed to include segmented flanges which fracture in response to forces applied to them upon engagement of the deformation. Slots defining the segments are filled with a rubber-like material which is bonded to the piston or gland thus providing a solid structure to enable appropriate sealing while not interfering with the fracturability of the segments.

The deflection coil system is the same as used for three electron beams of a TV colour SRT with delta-mounted electron guns. The image quality attained by this deflection coil system is extremely high even for a single beam deflection. The system provides a sharp focussing of the electron beam.
Patent DE-2835857-A1 (DE)
Inventor: DIEHL ERWIN DR
IPC: C23C2/30
Filed: 1978-08-16
Abstract: This feed salt is designed to permit low-fuming hot galvanising, in which the discharge is within the permissible limit of 80 mg/Nm<3>. The feed salt consists of 60-90% by weight of potassium chloride and/or sodium chloride, 5-20% by weight of zinc oxide and 5-20% by weight of ammonium chloride. All or some of the zinc oxide may be replaced by equivalent amounts of basic zinc carbonate, zinc hydroxide or zinc oxide chloride. The feed salt is applied in the conventional manner to the pickled metal object. The zinc oxide, together with the adhering excess of pickling acid, forms zinc chloride (component having a flux effect), and an aqueous film is formed which contains said chloride. Neither rinsing nor flux baths are required, therefore no waste water problems arise. The potassium chloride and/or sodium chloride make it possible to employ the low ammonium chloride concentration required for low discharge.

Title: Continuous drier for variable width textiles - has adjustable walls to provide hot air corridor of required span
IPC: F26B21/00
Filed: 1979-04-04
Abstract: A continuous drier for variable width sheet prods., such as tubular knitted fabrics, comprises a permeable conveyor belt which effects drying by means of air passing through the fabric. The air is circulated by hot air blowers. To conserve heat, two walls which form a drying corridor are adjustable wrt the span between them, according to the width of the tubular fabric. To avoid further possible heat loss, the damping elements are fixed to the walls and extend across the bare parts of the permeable belt. The drier is adjustable to varying widths of fabric or sheet, which results in a conservation of heat energy.

Title: Coating of workpieces via gas jet contg. materials - used esp. to adjust the oscillation frequency of quartz crystals, or to coat polymers with embedded particles
IPC: B05D1/10
Filed: 1980-01-25
Abstract: The gas jet and the particles (I) of coating materials in the jet are designed so particles (I) are embedded in the workpiece (II) and do not remove material from piece (II). One pref. application consists of increasing the thickness of a metal coating on a quartz oscillator or transducer, so a desired oscillation frequency can be obtd.. Particles (I) are pref. made of a similar or the same material as piece (II), whereas the gas jet pref. consists of, or contains, a non-oxidising or reducing gas, e.g. N2 or H2, and a gas jet contg. no particles (I) may be used before or after the coating treatment. The gas, particles (I), and piece (II) may be at the same or different temps. Similar conventional processes are used to remove material from a piece (II), whereas the invention is used for coating workpieces.

Title: Copying colour negative or diapositive picture - using individual illumination in prim. and opt. sec. colours in conjunction with analyser
Inventor: SCHLINKE GUENTER
IPC: G03B27/73
Filed: 1980-03-19
Abstract: In the prodn. of coloured pictures, the prim. colour densities of the negative are determined by individual illumination in the negative prim. colours by comparing the measured brightness with a standard value and equalising the different amt. of light by increasing or decreasing the strength of illumination or changing the exposure time. The novel feature is that this process is also used for the reproduction of diapositives by illuminating the diapositive in the prim. colours green, red and blue and equalising the amt. of light by changing the strength of illumination or the exposure time. Pref. the sec. colour densities are determined by individual illumination at least 3 times in narrow band filter colours, which are not the prim. colours. Colour contrast problems are avoided.
