Title: Liquid epoxy organopolysiloxanes for paper treatment - by alkaline equilibration of mixt. of epoxy organo-siloxanes in presence of water
Inventor: MENDICINO FRANK DOMINIC
IPC: C08G77/14
Filed: 1973-05-03
Abstract: Liq. epoxy-substd organopolysiloxanes are prepd by equilibrating a mixt of organosiloxanes, at least 1 of which contains an epoxy-substd org. substit, in presence of a basic equilibration catalyst, where the mixt contains is not >1 wt. % of water. The epoxypolysiloxanes are used in prodn of synthetic fibres and for improving the water-resistance of paper. Reaction may be in absence of solvents. The cost of removing water from the raw materials is avoided. In prepg. the initial mixt a 20 wt. % excess of epoxy monomer is sufficient, compared with a 100% excess in known processes. Loss of epoxy monomer o by polymerisation is avoided. The epoxypolysiloxanes show little discolouration on storage, and are of uniform quality.

Title: Thin-walled, cup-shaped mouldings - with embedded reinforcements, esp. welding protective (hand) shields
Inventor: HAUCK ALBERT
IPC: B29C44/12
Filed: 1973-06-06
Abstract: Suitably shaped reinforcement inserts (e.g. glass fibres) and a flowable or castable, hardenable plastics e.g foamable polyurethane, are introduced into a mould, shaped and hardened, and foamed inside a mould cavity which receives the reinforcement inserts and corresponds with the cup shape of the intended moulding, between components of the mould which is constructed as a split mould. The moulding cpd. thereby progressively fills the mould cavity and so completely embeds the reinforcements. Mouldings with relative complex configuration and thin walls may be produced.

Title: Ignition timing measuring system for IC engines - has differential stage to assist exact reading
Inventor: ZWANZGER HANS
IPC: F02P17/10
Filed: 1973-08-17
Abstract: The contact breaker signal oscillations are damped and fed to two stages of differing response waves. The differing square waves impulses are fed to a differential stage and substracted. The trailing edge (or terminating part of the signal) of the impulse signal is retarded and prevented from breaking into the next stage during the contact breakers opening period. The system processes the breaker signals as unfiltered as possible irrespective of the type of ignition. It also finds criteria for the opening and closing of the breaker independently of the higher and lower oscillations in the already known frequency ranges. The ignition impulses are in the region of 3,000 per minute for a maximum size of a six cylinder engine.

Title: Hydrodynamic transmission with Foettinger converters - having provision for separation of clean and air-contaminated fluid in vehicle drive
Inventor: HENRICH KURT
IPC: F16H41/30
Filed: 1973-10-23
Abstract: The fluid passes from a sump through a pump and a control valve to a Foettinger fluid torque converter. For filling the converter core the valve has a setting in which the core outlet is connected to a chamber for air-contaminated fluid, the chamber having a filtered drain into the sump. For driving the converter the valve has a setting in which the main outlet of the converter is connected through a restrictor to the sump. Thus only uncontaminated fluid reaches the sump. In the idle setting of the valve both outlets are connected to the chamber and the pump delivery is passed to a reservoir of the same capacity as the converter and having an overflow to the chamber. Thereby the level in the chamber is maintained constant.

Title: Sparking plug with integrated capacitor - has dielectric material and electrode elements arranged to form parallel capacitors
Inventor: HOLTIN UWE
IPC: H01T13/40
Filed: 1973-12-21
Abstract: The sparking plug with built in capacitor is intended for the supply of additional electric energy between the electrode point during starting to increase the conversion of energy by more efficient combustion of air fuel mixture. The element functioning as a capacitor is integrated into the module which, when assembled provides the necessary capacitance across the electrodes. The socket of the plug is designed so as to be the earthed electrode of the capacitor. The capacitance is increased by linking it with an electrode in the plug body. The central electrode which is part of the socket is linked to another electrode. The insulating material forms the dielectric, hence producing two capacitors in parallel. Preferably an external discharge path is provided.

Title: Heat treatment of faulty spots in capacitor prodn. - uses annealing of metal foil parts on insulating foils
Inventor: BETTHAUSEN FRANZ
IPC: H01G13/00
Filed: 1974-03-12
Abstract: The faulty spots in insulating foils, coated with regeneratable thin metal films for electric capacitors are repaired by annealing, during which the film coated insulating foils are guided over a reversing roll which is coupled to one pole of a voltage source, the other pole of this source being brought into capacitive and/or galvanic contact with the metal film. Rolled up coated insulating foils are inserted into a vacuum chamber, in which they are unwound annealed and rewound into the storage rolls. For this purpose preferably a vacuum with a residue pressure of less than 5.14-4 torr is used. The feed speed of the insulating foil for unwinding and annealing may be adjusted to the same value as used for metal film deposition onto the foil.
