Title: welding powder drying plant - with one drying oven superposed on several storage silos
Inventor: HEITZE BRUNO
IPC: F26B25/06
Filed: 1978-03-23
Abstract: A plant for drying and storing of welding powder consists of a single drying oven and several keep-warm storage silos. Each silo have a cover plate with bosses over which the feet of the drying oven can be lowered. A sleeve can be used to seal the discharge funnel with gate valve of the drying oven. The drying oven can thus be raised and lowered by lifting gear and used to charge dry welding powder into several silos where it is stored at 100 degrees C until needed. The storage at 100 degrees C ensures that the powder is of uniform quality. Different grades can be stored in different silos.

Title: Tractor implement for bale extraction - has cutting chain, holder and cut off mechanism driven by tractor
Inventor: ZADELHOFF BERNARD J V
IPC: A01F25/20
Filed: 1978-04-21
Abstract: The tractor implement is for extracting fodder in bale form from mobile silos. It consists of a support frame which can be connected with the tractor and has a tine fork at its end.

Title: Mechanical to hydraulic energy conversion system - uses hollow flexible body altered in cross section by mechanical forces
Inventor: DITS HERBERT DIPL ING DR
IPC: F15B5/00
Filed: 1978-05-31
Abstract: The system which converts mechanical energy into hydraulic or pneumatic or vice-versa, uses a hollow flexible elastic body. The wall of this body either varies or remains constant in size during conversion, and the limited volume of the body, which is filled with a medium, is altered in cross-section by external mechanical forces from an adjustable maximum to an adjustable minimum, forcing a set quantity of the medium out of it under pressure. It is returned to an adjustable maximum by feeding in medium under pressure, thus exerting mechanical forces against movable stops. The circumference of the body cross-section, and also its length between two end seals, are kept constant during distortion.

Title: Switching controller with current limiter - has operational amplifier each for controller and limiter which both control transistor applying supply voltage
Inventor: OBERMANN WOLFGANG
IPC: H02H9/02
Filed: 1978-07-07
Abstract: The controller has a filter section, a power amplifier, a current limiter and a voltage stabiliser. An operational amplifier is allocated to the controller and to the current limiter. The controller amplifier compares the output with a reference voltage. It switches forward or blocks a transistor applying the supply voltage of a certain frequency determined by a timing circuit connected to the amplifier non-inverting input. The other amplifier, associated with the limiter, controls the first amplifier which is made conductive when the current through an inductance at the stabiliser output reaches a certain value. It is blocked when the load current reaches the maximum limiting current value.

Title: Tyre retreading method - in which a belt reinforced tread is secured to a buffed carcass by an intermediate belt-like layer
Inventor: HEDLUND JOHN A
IPC: B29D30/56
Filed: 1978-10-27

Title: Directing gas flows for heating and cooling - in tunnel kiln with ceramic ware suspended from travelling roof wagons
Inventor: STROHMENGER WERNER ING GRAD
IPC: F27D99/00
Filed: 1980-07-14
Abstract: Ceramic material being fired in a tunnel kiln is suspended from insulated wagons which form the kiln roof and more on wheels along lateral channels. The material travels through a warming-up zone, a fining zone with heaters and a final coollinq zone. In the firing zone the combination gases enter transversely and then flow oppositely to the moving ceramic ware. In the warming -up zone gas enters from the side walls, near the roof and obliquely to the movement direction, while in the cooling zone the gas enters obliquely against that movement, near the kiln roof and floor. Cooling gas is also supplied near the roof in the central firing zone and flows adjacent the wagon channels. The firing process is made more uniform, with local overheating avoided, and the rapid cooling helps to avoid distortion of the ware. The cooling gas adjacent the firing zone protects the seals.
