Title: Ignition system for I.C. engine - has capacitor charged to battery voltage when contact breaker is open
Inventor: PAN PETER
IPC: F02P9/00
Filed: 1974-07-22
Abstract: A high voltage is produced in the secondary (L2) of a coil (L) by a contact breaker (SW1) in the primary circuit (L1) which is fed from the battery (B) through a diode (D1). A circuit in parallel with the primary coil branches from a point between the diode and the primary coil and contains a capacitor (C1) and a switch (SW2). The switch (SW2) is closed when the contact breaker (SW1) is open and vice versa. The capacitor charges when the contact breaker is open. The charge increases the primary current when the contact breaker closes, a higher current is broken and a higher secondary voltage is produced.

Title: Supported metal boride catalyst use in amalgam decomposer cell - for hydrogen prodn., for stability and resistance to damage and poisons
Inventor: BENDA KLAUS VON DR
IPC: C25B1/44
Filed: 1974-07-31
Abstract: Catalysts based on metal borides, which are stable in air and in storage, as in DT 2307852, are used for H2 generation in amalgam decomposer cells. These catalysts are used for cathodic H2 evolution in alkaline electrolytes and have activity comparable with Raney Ni. The compact metallic structure of the catalysts and good adhesion to the support ensure that they are not damaged mechanically by vigorous gas evolution. In contrast to other active catalysts, such as Raney Ni, these catalysts are stable at the normal operating temps. of ca. 100 degrees C. They are also relatively insensitive to catalyst poisons, e.g. Hg and its cpds. The catalysts are produced by the growth of x-ray-amorphous smooth boride films by deposition of the reaction prod. of water-soluble reducing B cpds. in aq. soln. with Ni++ or Co++ in the presence of a complexing agent for the metal ion at a concn. of metal ion of 0.02-0.2 M and of the complexing agent of 1-10 M in the original soln. on a metallic or non-metallic support. Borohydrides or borazanes are used in a concn. of 0.02-0.2 M as reducing agent, whilst the concn. of free metal ions is kept below 10-10 M and the temp. below 60 degrees C in deposition.

Title: Telephone instrument with key dialling - has excess voltage protection of individual sub-assemblies by Zener diodes
Inventor: BRANDSTETTER ALFRED DIPL ING
IPC: H04M1/74
Filed: 1974-07-31
Abstract: An excess voltage arresting circuit (a, GU2, K1, K2, b) with already existing contacts with different excess voltage resistances (GU1, GU2, K1, K2) does not pass through any further components or circuit elements. The above contacts are in fact two cradle contacts (GU1, GU2) connecting to the line the ringer or telephone instrument, and two keyboard contacts (K1, K2). The excess voltage resistance of the contact (GU1) connecting the ringer to the line is greater than that of the other contacts. When the circuitry is in dialling operation the cradle contacts (GU1 & 2) are operated as in speech operating state. During the transmission of dialling pulses one contact (K1) is open while the other (K2) is closed.

Filed: 1975-11-26
Abstract: A method is provided for growing highly oriented compound thin films on a substrate by subjecting the substrate to the vapor of a first single element which can react with the surface at a temperature sufficiently high for the reaction to occur which forms a single atomic layer of the first single element on the surface and then subjecting the thus formed surface with a first single element atomic layer thereon to the vapor of a second single element which can react with the first single element at a temperature sufficiently high for the reaction to occur so that a single atomic layer of the second single element is formed on the surface bound to the first single element. This procedure can then be repeated alternately subjecting the surface to the vapors of the first single element then to the second single element, etc. until the compound film reaches a desired thickness. There is further provided an apparatus for carrying out this method comprising a vacuum chamber with evacuating means, a support for supporting a substrate, sources for at least two vapors of two different single elements and operating means for providing on the substrate first a single atomic layer of one of the elements, and then a single atomic layer of the other of the elements.
Patent DE-2553937-A1 (DE)
Inventor: MARIANI LAURO
IPC: F02B75/02
Filed: 1975-12-01
Abstract: The technical problem which the crank mechanism solves is that of ensuring efficient lubrication between pin and crosshead and end bearing of the connecting rod, which, in the absence of the normal hydrodynamic supply, must protect the sliding surfaces from damage and seizing, without introducing excessive complications in the crank mechanism design. In order to solve this problem, the rod (1) of the piston carries on each of the opposite sides transverse pins comprising an external section (a) and an internal section (b) surrounded by the bottom bearings (a1) and (b1), respectively, and by corresponding caps (a2 and b2) mounted on the connecting rod (2). The axes of the pins (a) are eccentric with respect to those of the pins (b) of a section ( epsilon ) and these axes lie in a plane which intersects the axis of the rod (1). The intended application is in two-stroke Diesel engines. <IMAGE>
