Title: Boiling plate with temperature sensor - has bimetal discs in hub of plate operating transmission component moving switch contacts
Inventor: HERBST JOHANN
IPC: H01H37/54
Filed: 1976-11-15
Abstract: The boiling plate has also a temperature operated switch and a central sensor cup with a switching bimetal for the switch contacts operation.

Title: Patterning control system for textile, esp. tufting machines - overcomes rapid wearing of mechanical sensers by electronic circuit
Inventor: REYER ERNST
IPC: D05C15/20
Filed: 1977-06-18
Abstract: In a textile machine producing a pattern according to a programme, e.g. a tufting machine, an electrical impulse is generated, dependent upon the angular position of the main driving shaft. This is used to initiate and terminate the stroking of the needles in accordance with the pattern. The control system comprises electronic components and positioning mechanisms acting on the needles. The central electronic control unit for converting the patterning instructions into movements of the needles consists of a crossbar board with diode pegs. This has a power output going to relays and rectifiers. Alternatively, a programmed tape reader may be used. Makes it possible to reproduce the patterns much more accurately and overcomes the problem that the patterns are only short and have to be repeated frequently. At the same time the difficulties with the rapidly wearing out of the pattern sensing devices used with patterning drums are eliminated.

Title: Inhibiting corrosion of aluminium or its alloys - exposed to weakly acidic ammonium sulphate soln., by adding neutralised condensate of di:bromo-propanol and phosphorus pent:oxide to soln.
Inventor: BLUM HOLGER
IPC: C23F11/167
Filed: 1977-07-07
Abstract: The corrosion of Al and Al alloys in ammonium sulphate contg. solns. at 0-30 degrees C is inhibited by adding to the weakly acidic soln. at pH 2-4, a condensn. prod. of dibromopropanol and phosphorus pentoxide. The inhibitor is prepd by heating a mixt. of 2-3 moles dibromopropanol and 1 mole phosphorus pentoxide until a clear soln. is obtd., and neutralising the reaction prod. with ammonium and/or another alkali hydroxide or -carbonate. The inhibitor is added to the weakly acid ammonium sulphate soln. at a concn. of 0.5-20 wt.% based on the ammonium sulphate content. Levels below 0.5 wt.% are not effective and higher ones are only useful if the ammonium sulphate concn. is very low. The soln. may contain, in addn., a fire-proofing agent and an anionic or non-ionic wetting agent.

Title: Process for removing slot insulation between commutator segments - has laser device directed at commutator clamp on and rotated with support device
Inventor: BERTRAM CLAUS
IPC: B23K26/08
Filed: 1977-07-22
Abstract: In order to remove the slot insulation, the commutator (3) is mounted on a rotary device (1). During rotation a feed device (6) with a laser (7) is guided along the slide surface of the commutator for carbon brushes. During laser irradiation the slot insulation (5) between the commutator segments (4) is removed to a given depth by the laser beam (8). Pref. the rotation of the commutator is continuous, while the feed device is moved longitudinally parallel to the commutator long axis. Thus the laser beam follows an overlapping helical trace on the commutator slide surface. Alternately the commutator may be rotated in partial steps corresponding to the number of slots.

Title: Separation plant to remove magnetisable particles - conveys particles to magnetic field by turbulent carrier gas from compressed air blower
IPC: B03C1/029
Filed: 1978-01-24
Abstract: The separating plant consists of a housing in the lower part of which chambers are provided. The chambers receive compressed air through pipes. The chambers are covered by a screen consisting of perforated, or slotted sheet metal or fabric. Adjacent to the first chamber, the material inlet is fitted distributing the material by means of proportionating wheel onto the screen.
