Patent DE-2755272-A1 (DE)
Title: Molten metal doser for die casting machines or foundries - where all critical moving parts are shielded from heat and dirt
Inventor: ENGEL WERNER
IPC: B22D39/02
Filed: 1977-12-12
Abstract: Metal dosing appts. uses a scoop driven automatically to deliver an exact dose of molten metal to pressure die casting- or similar-machines, or to foundry moulds. On top of a stationary pillar is a housing (a) contg. a motor driving two pivot arms between two end positions. The other ends of the arms are located on pivots on a second housing (b) contg. a ring gear actuated by a crank driven by a work cylinder. Housing (b) is mounted on the top end of a vertical tubular carrier contg. a drive rod rotated by the ring gear; and the bottom end of the drive rod is fitted with a bevel gear meshing with a second bevel gear fixed to the scoop. Rotation of the ring gear thus tilts the scoop. Housings (a,b) carrier, and a flexible bellows, shield the working parts described from heat-radiation and dirt or dust. With conventional dosing appts., heat radiation from the molten metal etc. causes the thermal expansion of the mechanical parts, such as driving chains, so accurate location of the doser is not maintained and therefore the wt. of the dose varies. The invention eliminates this disadvantage so a constant wt. or vol. of metal is provided.

Title: Record disc groove cutting control - using control signal derived from signals to be recorded, which is squared to generate cut depth
Inventor: KERN OTMAR
IPC: G11B3/72
Filed: 1978-02-28
Abstract: The control process is used for depth recording of signals on a record disc, in which the cutting force does not depend linearly on the cutting depth, but increases with its square. A control signal(S1) is derived from the signal to be recorded and is squared to generate the desired cutting depth. The circuit for carrying out this process contains a squaring network, through which passes the control signal, the network having a transmission function UA = UE2 X Z. where UE is the input voltage, UA the output voltage, and Z a freely selectable matching factor. The output voltage is supplied to an electromechanical transducer(W), associated with recording element(SB), which converts the signal into a force determining the groove depth.

Title: Motorised cutter mechanism for rods - has power tool advancing in cutting direction and swingable in plant perpendicular to advance
Inventor: HEIBERGER ERNST
IPC: B23D45/02
