Patent DE-3931414-A1 (DE)
Inventor: KUEHNERT GOTTFRIED DIPL ING
IPC: D04B1/24
Filed: 1989-09-21
Abstract: The invention concerns a flat knitting machine with two main and auxiliary needle boards (3, 4 and 5, 6) and in which at least one auxiliary needle board (5, 6) is divided into at least two zones (5R, 5M, 5L; 6R, 6M, 6L). By moving these zones (5R, 5M, 5L; 6R, 6M, 6L) together or with respect to each other, any kind of knitting pattern can be produced easily. In particular, it is possible to produce complete items of knitted clothing in a single operation, without the need for additional assembly operations. Also described are knitting procedures with which complex new patterns can be produced in a single operation in individual knitted-fabric part-items and/or complete items of clothing.

Title: Etching unit esp. for printed copper circuit boards - in which used rinsing water is distilled to recover pure water and ammoniacal etchant to which ammonia is added prior to recycling
Inventor: HAAS RAINER ING GRAD
IPC: H05K3/06
Filed: 1989-11-02
Abstract: Etching process, esp for producing printed circuit boards (2), has the novelty that the rinsing water which is contaminated with the etching agent is purified in a distillation unit (36) and recirculated to rinse the boards again. The ammoniacal etching agent recovered in the residue has ammonia added to it before it is recirculated to etch the boards. A buffer tank (3) is positioned in the circuit between the distillation unit (36) and the one or two rinsing machines (15,22) and serves as an intermediary store for contaminated rinsing water. A second similarly positioned tank (45) stores the purified water. Pref the pump (32) which feeds contaminated water to the first tank (33) acts as a double pump with the other pump (46) which extracts purified water from the second tank (45). The pumps are powered by a common motor (48) which is connected to a supervisory unit (49) having a sensor (50) which detects the entry of a board (2) into the etching unit (1) and initiates the action to operate the motor. A third buffer tank (53) positioned between the distillation chamber (37) and the etching unit (1) stores the recovered etching agent and receives the ammonia used to rejuvinate the agent. A level regulator (57) monitors the level of etching agent in the sump (10) of the unit (1). Should this level fall below the desired value a pump (55) is actuated to extract etching agent from the third tank and feed it to the sump. ADVANTAGE - Recycling the purified water and regenerated agent avoids the damaging effects arising from the disposal of such chemicals in other designs of etching installation.
