Patent KR-820000570-B1 (KR)
Title: Method of dissolution of metals
Inventor: READIO P
IPC: C09K13/04
Filed: 1978-11-07
Granted: 1982-04-14
Abstract: In the etching of Cu in the prepn. of printed-circuit boards, improved metal dissoln. rates are obtained when using an aq. soln. contg. H2SO4, H2O2, and certain primary diols[I, R1 = cyclic paraffin or -(CR2R3)n-; R2,R3 = H, C1-4 alkyl; n >=2 .  These additives have a dramatic effect in improving the etch rates both in the absence of added chloride ions or the presence of considerable quantities of chloride, i.e. 45 ppm.  In 1 example, without chloride ion, the time required to completely remove the Cu from the bottom side of a laminate was reduced from 270 sec. to 75 sec. by adding 1,4-cyclohexanediol.

Title: Method for the treatment of packing material
Inventor: NISKE JORUGEN
IPC: B31B1/74
Filed: 1985-11-05
Granted: 1989-04-15
Abstract: The method involves making a web by passing it in close contact over die rolls (140), each with raised portions (139) which extend over the contour of the rolls.  One or more grinding rolls, rotating at high speed, are arranged adjoining the die rolls.  The separation between the die rolls and grinding rolls (142) corresponds to, or slightly exceeds, the blank or web thickness. The separation between the grinding rolls and the raised surfaces of the die rolls is less than this.  The web, when passed over the die rolls, will be pressed locally by the raised surfaces of the die rolls into contact with the grinding rolls.  Parts (143) of the web material are thus ground away, to form reduced thickness portions.

Abstract: A thermoplastic tape is wrapped around a package and is tightened by the disclosed strapping or banding apparatus. The ends of the plastic tape can be welded together by a combined strapping and sealing apparatus or even with a separate sealing apparatus. The strapping apparatus includes a positioning system which ensures that a slotted wheel intended for tightening the plastic tape, once the operating cycle is complete, always assumes an optimum position for the re-insertion of the plastic tape. The use of the strapping apparatus is thereby substantially facilitated, since the operator normally does not have any hands free to adjust the slotted wheel that would otherwise be necessary for tape insertion.

Abstract: A tumble dryer for small articles of clothing having no motor or heater utilizes the output of a hair dryer to both rotate a drum containing the articles of clothing and to dry the articles. Turbine blades mounted on the periphery of the drum slowly rotate the drum to prevent uneven drying of the clothing in the warm air output from the dryer. A tray mounted beneath the drum can be used to catch water dripping from the clothing. Removing the tray allows the hot air to escape from the bottom of the unit for warming the room or drying hands. The tumble dryer and its associated hair dryer are preferably wall-mounted.
