Title: Data switching control for status inputs - counter controlled data selector output is compared with status register output
Inventor: CLAUSS MARTIN
IPC: G06F13/22
Filed: 1974-04-25
Abstract: A status monitoring unit for a process permits any existing condition to be reactively compared with the designated condition and any variation to be recorded. Status units on the process, to the form of relays for example, operate through input interfaces with a data selection unit. An 'n' state counter triggered by impulses cycles the data selector through the status signal inputs. The impulse input also operates two registers; one containing the required status while the other stores any difference in status. The output of the data selection unit is compared with the output of the status register in an EX-OR and the information transmitted via a memory to central control. The impulse signal synchronises the activity of the two registers and the data selection unit.

Title: Corrosion resistant surface coatings which contract on cooling - have extra anchorage points, to obviate cracking which consists of undercut blind bores
Inventor: ETTRICH BRUNO ING GRAD
IPC: B05D7/22
Filed: 1975-08-19
Abstract: Surfaces exposed to corrosion, eg the interiors of pumps, are covered with powdered polytetrafluorethylene, which is then sintered at 300-400 deg.C to form a corrosion-resistant coating. The coating contracts considerably as it cools: the tensions this sets up within it relieve themselves where the coating can move across the surface, and thus become concentrated at the anchorage points, where the coating cannot move. If the distance between the anchorage points is considerable, the coating cracks round them. The spacing between the anchorage points is reduced o the level where the contractive force between any two of them is insufficient to cause cracks. The additional anchorage will be undercut round (or square) holes (16) in a pattern of isoceies triangles whose sides are one to six times the diameter of the holes.
