Title: Thin-layer chip capacitor - has insulating substrate, dielectric film on base electrode and nickel contact surfaces
Inventor: EDMOND MICHAEL DIPL PHYS DR
IPC: H01G4/08
Filed: 1975-03-26
Abstract: The thin layer chip capacitor consists of an insulating substrate, a base aluminium electrode, a dielectric deposited on the base electrode, an aluminium counter-electrode and solderable terminal contact areas on both electrodes, these areas being of nickel. This type of capacitor affords mass production by selecting the substrate of suitable size. Instead of conventional layer combination only one layer is used and the expensive gold used in conventional capacitors of this type is replaced by nickel. The replacement of the chromium-nickel-gold combination permits better utilisation of existing surfaces, since nickel does not produce with aluminium a harmful alloy.

Title: Digital frequency display circuit - is in broadcast receiver working in AM and FM ranges and has amplifier for local oscillator
Inventor: KLANK OTTO
IPC: H04B1/16
Filed: 1975-09-16
Abstract: The wideband amplifier is common for oscillations of the AM and FM oscillator, and is followed by a frequency divider with several stages, whose division ratio depends on whether the receiver operates in the AM or FM range. At least one division stage is a decimal counter (1) with two resetting inputs (5, 6) by which it can be set to the figure nine. Resetting input (5) is operative only when a certain logic potential is applied to the resetting input (6). The decimal counter (1) counts trailing edges of rectangular pulses applied to it from the wideband amplifier (8). Leading edges of rectangular pulses are applied to the resetting input (5) through a differentiating circuit (7, 9), while an 'O' or '1' potential can be applied to the input (6) by the range switch through a control wire, so that the counter (1) division ratio is changed from 1:10 to 1:1.

Title: Steam driven power generating cycle - uses heat of condensation to heat helium which drives auxiliary turbine
Inventor: GULAIF JOSEF
IPC: F01K23/04
Filed: 1976-03-12
Abstract: Live steam from a boiler (12) enters a reciprocating engine (2). The exhaust from this passes through a turbine (3) into a condenser (15) which operates under a vacuum. A pump (4) forces helium gas through the condenser in which it absorbs the heat given up by the condensing steam. The heated gas then flows out through a turbine (5) in which the heat it has absorbed is converted into useful work. The exhaust from the turbine is piped through a coil (16) in a water tank (6) in which the exhaust is cooled. It is then returned through a pipe coil (18) to the inlet of the pump. Both the steam turbine and the helium turbine drive electrical generators (14). Atmospheric air can be used instead of the helium.

Title: Combustion engine with angular oscillating piston - has combustion space shaped so that turbulence is induced in gases just before ignition takes place
Inventor: AUGUST PAUL DIPL ING DR
IPC: F01C1/063
Filed: 1976-03-19
Abstract: The combustion engine consists of a cylinder (1), a shaft (2) to which a piston (3) is connected and a piston (4) which is attached to another part of the shaft. The cylinder has a gas inlet (5) and an exhaust (6). The two pistons are interconnected by a lever system or other suitable drive mechanism. During rotation there is a relative angular movement between the pistons so that the space between the pistons is alternately enlarged and made smaller. The combustion chamber between the pistons is alternately enlarged and made smaller. The combustion chamber between the pistons is shaped so, that when the two pistons approach each other, a narrow gap (10) is formed which squeezes the gases into the remaining part of the combustion chamber. The gases squeezed out of the gap (10) cause turbulence in the combustion chamber, which results in more efficient combustion and cleaner outlet gases.

Title: Electric cathodic deposition of inorganic powders or plastics - to improve corrosion resistance or bearing properties of substrates
Inventor: BROWN HENRY
IPC: C25D13/02
Filed: 1976-03-20
Abstract: In a process for the electric cathodic deposition of films of fine particles of water-insoluble powder (e.g. plastic), the particles are deposited from a dispersion in agitated aq. solns. of the salts of monovalent alkali metals or ammonium cations, and that the electric deposition occurs in the absence of ions which could be deposited electrolytically. The water-insoluble particles are pref. (a) BaSO4; (b) boron; (c) silicon; (d) SiC; whereas the monovalent cations are pref. sulphate salts, carbonates or sulphonates in the aq. soln. Used, e.g. when BaSO4 is deposited onto Ni and then 0.005-0.05 mm Cr, Ag, Au or Rh, a fine satin finish is obtd. with exceptional corrosion resistance in industrial or marine atmos. because the BaSO4 produces microporosity in the final layer of Cr etc. thus reducing the anode current density and the speed of pitting.
