Patent DE-3026456-A1 (DE)
Title: Powder lacquer hardener for lustreless coatings - obtd. from mono:salts of aromatic poly:carboxylic acids and phenyl-di-imidazoline using an aq. solvent
Inventor: NEUBOLD KURT DIPL CHEM DR
IPC: C08G59/50
Filed: 1980-07-12
Abstract: Hardeners for powder lacquer systems are mfd. from monosalts of aromatic polycarboxylic acids having at least three carboxyl gps., and 2-phenyldiimidazoline, by introducing the acid as an anhydride that is hydrolised in the presence of a 2-4C alcohol in water. After this the 2-phenyldiimidazoline (delta 2) is added as a solid to the aq. suspension or acid soln. and the precipitated monosalt is removed. Pref. an alcohol concn. of 3-15 wt.% and more specifically of 5-10 wt.% w.r.t. the wt. of the polycarboxylic acid anhydride, is present in the water during hydrolysis. The result is only obtd. when the anhydride is used as the starting material and the alcohol is added only during hydrolysis of the anhydride into an acid. Suitable alcohols are ethanol, n-propanol, isopropanol, sec. butanol, ethylene glycol, etc.. Lustreless coatings which exhibit excellent mechanical properties such as those traditionally obtd. using poisonous or inflammable liqs. as solvents are produced using water as a solvent.

Title: Resistance braking circuit for chain-saw motor - has temp. sensitive resistance in series or parallel with field winding, across armature
Inventor: MITTMANN HANS-GEORG DIPL ING
IPC: B27B17/08
Filed: 1980-09-18
Abstract: The resistance braking system for universal motors for chain saws, lawn motors, hedge shears etc. uses a temperature sensitive resistance (7) as a current limiting device. The motor has an armature (1) and a series field winding (2). When the power supply is cut off, the switch (5,6) inserts the resistance in series with the field winding, and both in parallel with the armature. The resistance reaches 90 per cent of its maximum temperature after a maximum of 50 per cent of the braking time between switch operation and complete stoppage of the motor. The resistance is mounted in the flow of cooling air to the motor. Its measurement at right angles to the direction of flow is less than 18 mm. An alternative circuit has the resistance switched in parallel with the field winding.

IPC: A61C1/08
Filed: 1980-09-30
Abstract: A dental handpiece arrangement which has a drive transmission for transmitting the rotation from a motor to a socket receiving the tool in the head of the handpiece comprising a first drive shaft having a pair of coaxially arranged drive gears of different numbers of teeth, a second drive shaft having a gear engaging one of the pair of coaxial drive gears characterized by the second drive shaft being composed of a first drive shaft portion and a second drive portion which are interconnected by meshing gears providing a change in the gear ratio. Preferably, the two drive shaft portions of the second drive shaft are mounted in a housing with a gear at each end and the housing is adapted for being supported in the handpiece arrangement in two different positions so that in a first position, a gear at one end is engaging one of the pair of coaxial gears of the first drive shaft and in the second position the gear at the opposite end is engaging the other of the pair. Thus, by changing the position of the housing, a continuous stepping-up of the gear ratio can be obtained or by reversing the position of the housing a continuous stepping-down of the gear ratio can be obtained.

Title: Continuous cementation of metals from their solutions - in vibrating container with partition baffles
Inventor: MEGERLE FRIEDRICH
IPC: B01D21/00
Filed: 1980-11-25
Abstract: Plant for the continuous precipitation (cementation) of metals from their solns., e.g. copper from a copper soln. or impurities (Cu,Cd,Co,Ni) from a zinc sulphate soln., consists of a vibrating container, supported on oscillatory elements and filled with granules of a precipitant. At least one baffle is fitted after the inflow and one before the outflow opening, both leaving a gap near the bottom of the container. An unbalanced drive (12) causes the container (10) to oscillate on the flexible supports (11). The fresh metal solution enters through the inlet (13) and is forced by the baffles (18,19) to pass the entire bed of precipitant granules (20) before it reaches the outflow (14). This ensures a good functional reliability, free from clogging, and a high efficiency.
