Title: Micro-plasma welding using transferred arc - where pilot arc circuit simplifies striking of main arc
Inventor: HILDEBRANDT PETER DR
IPC: B23K9/067
Filed: 1977-01-07
Abstract: The main arc (b) is struck for plasma welding using a transferred arc (b), esp. in microplasma welding. A pilot arc (a) is formed, and then the main arc (b) voltage is applied, followed by immediately increasing both the current for arc (a) and the flow of plasma gas for a brief period. The pref. appts. uses a power supply (a, b) for each arc (a, b), where circuit (a) contains a limiting resistance connected in parallel with a resistance in circuit (b). The plasma gas supply pipe contains a main valve wity a bypass fitted with a solenoid valve operated by switch contacts. Used e.g., in the welding of very thin metal sheets using a non-consumable welding electrode, where the main arc (b) can be struck without difficulty.

Title: Load dependent gear control - has input shaft power transmission via two gearwheels to planet wheel shaft
Inventor: WITTROCK LUDWIG
IPC: F16H3/66
Filed: 1977-01-19
Abstract: The gear control is brought into service when movement under load occurs. A power transmission from an input shaft (1) is via two gearwheels to a planet wheel shaft. To this conversion planet wheels of differing size are firmly connected. For each planet wheel, a toothed crown is arranged in the gear housing (10), the crowns having an inner toothing, and on their running surfaces (16) can either slide, or can be retained as stators via one of the five stop pawls incorporated (17-21). Due to the rolling movement of a planet gearwheel the retained stator causes a rotary movement of the planetary crank (23), and in turn rotation of the driven shaft (24).

Title: Needle for introduction of preserving fluid into timber - has hexagon head on sealing block of large dia. and threaded point with capillary bore
Inventor: BINKER HANS
IPC: B27K3/10
Filed: 1977-03-21
Abstract: The impregnating needle is for the introduction of preserving fluid into timber and has a threaded point to screw into a drilled hole and a sealing block at the other end, of larger than the hexagon head.

Title: Compact adjustable flow high pressure cleaning appts. - has by=pass valve in suction valve casing without weakening cylinder chamber
IPC: B08B3/02
Filed: 1977-05-17
Abstract: The flow controller is formed by a by-pass pipe inside the housing of the suction valve (6) through which water is drawn up by a pump from the water chest into the cleaning apparatus.
