Title: Pressure sensitive adhesive contg a polyvalent - metal compound
Inventor: THOMAS SANDERSON FRANK
IPC: C09J7/38
Filed: 1970-04-27
Abstract: The adhesive contains a compatible polyvalent metal compound (I) with an addition polymer (II) of an unsaturated monomer (alkyl C2-12 acrylate), and a polymerisable unsaturated carboxylic acid (III). The molar proportion between I and -COOH, -COONH4 or -COO amine groups is 0.01 to 2.0. The polymer contains 10 - 99.7 wt.% of II, 0.3 - 10 wt.% III and the balance is a monomer which imparts glass transition temp. of less than 0 degrees C to the polymer. The inclusion of I reacting with free acid groups in the polymer provides an improvement in shear strength of the adhesive while maintaining its tackiness, which is normally reduced by known additives. An example of I is zinc octoate.

Patent DE-2363361-A1 (DE)
Title: Balance control for electronic amplifier - designed for single potentiometer stereo balance without increasing cross-talk or overloading
Inventor: ANNER PETER ING
IPC: H03G3/02
Filed: 1973-12-20
Abstract: The main disadvantages of current types of balance controls are that single potentiometer types with a grounded wiper have an interconnecting current path in the potentiometer track, giving increased cross-talk, and that reduction of signal in one channel gives increased signal in the other channel. The proposed control is also used with matching resistors, a grounded wiper and with the two channels to be balanced connected to its ends. The track has however an additional grounded tapping at its mid-point. This point is silvered across its width to give it a low resistance. When the wiper is moved to one side or the other the resistance to ground is lowered without affecting the other channel. The low resistance to ground at the midpoint gives 100% isolation between channels.
