Title: Production of sodium bicarbonate by reversion of nahd13-containing double salt
Inventor: COPENHAFER WILLIAM CLARK
IPC: C01D7/14
Filed: 1984-07-31
Granted: 1989-02-09
Abstract: Sodium bicarbonate is produced by introducing solid sodium sesquicarbonate and/or Wegscheider's salt into a reversion slurry, saturated with respect to bicarbonate and containing at least 10 wt. % solids, to effect rapid and complete conversion of the feed solids to crystalline sodium bicarbonate which is recovered from the slurry. Carbon dioxide is introduced into the reversion liquor to maintain its composition at a relatively constant value, preferably in a region of the Na2CO3-NaHCO3-H2O phase diagram that minimizes the equilibrium partial pressure of CO2 vapor above such liquor.

Patent DE-3583685-D1 (DE)
Inventor: WHEELER DALE K
IPC: H02K15/095
Filed: 1985-06-14
Granted: 1991-09-05
Abstract: A method and apparatus for winding field coils on internal poles of stator bodies, particularly for electric motors, have a magnet wire feeding needle or needles displaced eccentrically from the central armature axis of the stator body. The or each such feeding needle is disposed to reciprocate and partially rotate on an eccentric axis located between the central armature axis and the internal pole being wound. Due to this eccentricity, during the partial rotation of the feeding needle, the end turns of the coil are lifted above the end of the pole and laid more precisely in place. This enables the conventional winding forms to be eliminated allowing a reduction in the length of the reciprocating stroke of the feeding needle and faster winding with reduction in "snap back" effect. A further cost saving occurs from a shorter length of the end turns resulting in less wire being used.

Title: Adjusting device for moving the rolls of a rolling mill along the rolling axis
Inventor: SCHILLER GUNTER
IPC: B21B31/20

Granted: 1989-08-17
Abstract: The rolls of a rolling mill, especially the working rolls, are horizontally shifted by a compact adjusting device, with use being made, as required, of guide pieces. The device is readily arranged in cylinder blocks, and the movements of the device can be easily monitored, transmitted, and set. The predetermined motions are carried out in rigidly controlled manner and no elastic yielding is allowed because of pressure plates extending in the windows of the base frame members. The pressure plates can be horizontally aligned and they cooperate with the holding elements which are to be shifted. The pressure plates are supported by wedges which can be shifted horizontally and transversely with respect to the plane of the frame, by way of pressure posts which operatively engage the pressure plates.

Abstract: In a hydraulic percussive machine with a shuttle valve 19 to control the flow of fluid to and from a drive chamber 14 there are no timing lands on the piston 11 and a seal 25 between the drive and return chambers. This is made possible as a result of a restrictive orifice 24 connected to the shuttle valve of conventional design and a port 22 in the return chamber 15 which is covered and uncovered by the piston 11. When the port 22 is uncovered the shuttle valve 19 moves over under pressure. When the port is covered, pressure leaks through the orifice 24 to that the shuttle valve moves back again.
