Title: Chrome plating baths - automatic bath quality control
Inventor: YAGISHITA AISABURO
IPC: C23C22/86
Filed: 1972-12-21
Abstract: A pumping system, activated by a pH meter monitor, and connected to a H type ion exchange resin column with return pipes, is detailed for use on chrome plating baths, partic. where low conc. e.g. CrO4 10g/l plating solns. are used. By monitoring pH the build up of impurity ions e.g. Zn2+ and Cd2+ in partic., can be judged and these can be removed by the cationic H type ion exchange resin when the soln. is pumped through the resin column after the pump has been activated by the pH monitor. Replenishing soln. tanks may also be brought into line by a further pump. The resultant monitored plating soln. can thus be continuously used for the prodn. of high quality plating deposits.

Title: Hinge pin with axial lubricating grooves - has groove end closing features for forming closed lubricant chambers
Inventor: BROCKHAUS ERNST
IPC: E05D11/02
Filed: 1973-10-25
Abstract: The hinge arrangement which is used especially for rotating panels has hinge made from two components which are fitted into each other. The hinge has a hinge pin which connects two hinge halves. This pin head is knurled so that it is forced into the seat and it forms press fit. The pin has side grooves and the free end openings of the grooves are closed by peened material or by welding. The knurled top end is closed by the knurled section and the head. Grease is injected into the chambers by the radial bore in the middle part of the hinge. This bore is closed with the cap. Hence the longitudinal grooves form closed grease chambers which retain lubricant for a long period. The closed ends ensure that the lubricant does not leak out.

Title: Alkali tetraphenyl borates and 2,(2,di)-alkyl hexane diol zirconate - used as esterification catalysts in unsatd. polyester prepn
Inventor: SCHADE GERHARD DR
IPC: C08G63/52
Filed: 1973-09-23
Abstract: Unsatd. polyesters are prepd. from unsatd. dicarboxylic acids and polyalcohols using, as esterification catalysis, alkaline tetraphenylborates of formula : (where Me = Li, Na, K, Rb or Cs), or 2-alkyl-hexane diol-1,3-or 2,2-dialkyl-hexane-diol-1,3-zinconates, the alkyl having 1-4C.

Title: Automatic holder for motor vehicle door - has spring loaded pin with ratchet for locking door at any angle
Inventor: BRUCHE EDMUND
IPC: E05C17/04
Filed: 1974-03-05
Abstract: The door of the motor vehicle is kept open in position at any predetermined angle by means of the automatic device. The mechanism has a baseplate on which a locking pin loaded by a spring slides in a guide. The locking pin is at all times held firmly against the vehicle body door pillar. When the door is moved the pin follows the door displacement and maintains contact with the pillar. On actuating the door the locking pin displacement pivots a lever about a pin and this lever has at its other end a ratchet segment with teeth which are in engagement with a ratchet pawl hook. This ratchet arrangements holds the door locked against movement in the closing direction. The door can be closed after actuating a pivoted lever whose cam will lift the pawl out of engagement with the ratchet and hence the spring loaded pin is forced back into its seat against the actuating spring force.
