Title: Enclosed electroslag remelting furnace - with upper and lower part and movable valve disc
Inventor: SPENGEMANN HEIKO W
IPC: F27D99/00
Filed: 1989-04-20
Abstract: A totally enclosed remelting furnace has a valve housing with a valve disc arranged on a lower part of the furnace with an ingot mould. The valve housing supports the upper furnace part with its current supply and is insulated from both parts.  A current conductor joins the two furnace parts coaxially to the centre line and can be moved enough to deposit the valve disc belo the conductor on the valve seat, after the consumable electrode has been remelted to an ingot in the mould of the lower part. Specifically the vacuum arc furnace with the consumable electrode (1) has a lower part (8) with a water-cooled (11) ingot mould (9) and an upper part (13).  A water-cooled (21, 22) current conductor (20) contacts the lower part by its serrated surface (23) on the flange (23a).  Then the electrode (1) has been melted to an ingot, the conductor and the upper part are lifted by the power cylinder (28) and a valve disc (36) on two roller casings (42) is moved by endless chains (39) on rockers (30) above the flange (10) and is deposited on the valve seat (10a).  The upper part can now be replaced by another with a new electrode. ADVANTAGE - This provides coaxial current paths between upper and lower furnace part and eliminates any heating of components away from the conductor.

Title: Hydraulic pump for automotive transmission - is driven via gear pump whose output decreases with transmission ratio
Inventor: SCHOPF WALTER
IPC: B60K25/02
Filed: 1989-04-24
Abstract: The hydraulic pump supplies lubricant, pressure and coolant to automotive transmission and auxiliary units, particularly a step-lessly variable transmission unit or power-assisted steering gear.  Working with the variable-ratio transmission mechanism(5, 6, 7,) the pump(14) is so driven (13, 15, 17) that its speed decreases as the output speed appraches the input speed. The drive mechanism to the pump itselt consists of a gear pump(12)., its coupling members(17, 18,19) reducing its output in direct proportion to the reduction in the difference between input and output speeds, by reducing the difference in speeds bet-ween the gears and housing of the pump(12). One or more further machines(24) forming auxiliaries are connected after the pump(14) . USE/ADVANTAGE - Reduction of pump drive losses in hydraulic trans-mission.
