Title: Exhaust gas vol. controller for oil-heated hot water plant - has flap throttle in exhaust gas pipe, controlled by thermostat
Inventor: WANDER WERNER
IPC: F23N3/04
Filed: 1974-01-17
Abstract: Controller for the exhaust gas vol. of burners for water heating plant, esp. for oil burners, has a throttle flap in the exhaust gas connection. The flap is adjustable by a thermostat acted on by the temp. of the operating water of the plant; the thermostat moves the flap in the opening direction when the operating water temp. falls below a preset value. Preferably the thermostat simultaneously switches the fan of the burner. The flap is operable by an electromagnet, which can be switched by the thermostat. Heat losses are minimized, and fuel use is reduced.
Patent DE-2405994-A1 (DE)
Title: Aligning fibres for bonded mouldings taking heavy loading - electrostatic fields line up fibres in direction of main loading
Inventor: ZILCH WERNER
IPC: B27N3/14
Filed: 1974-02-08
Abstract: The strength of mouldings pressed from a mixt. of fibres, esp. of wood, and a bonding agent, is improved considerably when the fibres in a mould are agitated in a direction transverse to the lines along which the main loading will be applied in the finished prodt., so that the fibres line up along these lines and are then bonded under pressure. Whilst the agitated fibres are in a state of buoyancy, they may further be exposed to an electrostatic field acting along lines parallel to those of the anticipated main loading of the moulding; the vibration being cut off first and then the electrical field. Similarly, fibres fed to the mould on an air stream may also be lined up electrostatically. Permits the prodn. of mouldings having the requisite strength in the heavier loaded zones, without an excess of matl. where it is necessary.

Title: Open-top piston for hydraulic pump - contains cushioning plunger throttling flow to low pressure oil when piston near top dead centre
Inventor: STRAUFF GUENTHER
IPC: F04B11/00
Filed: 1974-03-16
Abstract: The pump is of the type provided with a piston which is open-ended in the direction of the pressure chamber, its cylindrical bore containing a plunger axially movable between two stops within the piston, the space within the piston communicating with a low pressure oil chamber via a bore in the pistons.

Title: Aircraft contra-rotating rotors - each is integral with one half of electric motor with poles working together
Inventor: KLING ALBERTO
IPC: B64C27/12
Filed: 1974-04-29
Abstract: The two coaxial contra-rotating rotors each turn freely about a common imaginary axis on the aircraft frame or a support member. Each rotor (29, 30) forms part of an electric motor, equivalent to the rotor and stator (10, 11) and acting against each other so as to cause rotation in opposite directions. The poles of one or both parts are supplied with alternating current from a generator, typically of the high-frequency type. The generator can have a small number of poles and run at high speed, being of the polyphase type, while the number of poles of the rotors can be greater. Alternatively the generator can be a direct-current one, with an electronic or mechanical converter producing the high-frequency current for the rotors.
