Patent DE-2529694-A1 (DE)
Title: Emergency supply of air of combustion for steam boiler - driving turbine compressor supplying gas, e.g. to a blast furnace
IPC: F01K15/00
Filed: 1975-07-03
Abstract: Process for the emergency supply of air for combustion, necessary for heating a steam boiler feeding a steam turbine driving a compressor. The novelty is that when a breakdown in the normal air supply occurs, part of the gas or gas mixt. delivered by the compresser is removed and used as a propellant which sucks in the atmos. by an injection effect and thus provides the air for combustion required to heat the boiler. In the pref. defice, a branch-pipe fitted with a valve is provided on the compressor outlet pipe and the compressed gas is blown through a tuyere which sucks in air from the atmos. the resulting mixt. being fed into the air inlet on the boiler, valves being provided on both air inlets. See also 832041. Ensures a continuous supply of air to the boiler so that any breakdown in the usual supply cannot interfere with the continuous compression of gases or air supplied e.g. to a blast furnace.

Title: Async. external rotor electric motor - has rotor reinforced by cross straps to increase natural rotor frequency and prevent resonance during braking
Inventor: KIRCHENMAYER GEORG DR ING
IPC: H02K17/16
Filed: 1975-09-20
Abstract: The asynchronous external rotor motor with increased or natural frequency of mechanical oscillation of the rotor has side walls of the rotor winding slots reinforced by intermediate cross-strapsor bars. The cross-strap or bar can be made of magnetically conductive or non-conductive materials. The straps or bars form a unit with each two adjacent rotor teeth (set around the whole periphery of the rotor ring. The reinforcement changes the natural frequency or the rotor in the same way as increasing its mass would, but more cheaply. The natural frequency then no longer interferes with braking or acceleration.

Title: Automatic production line recognition system - detects photographic prints rejected at inspection stage and marked with pencil
Inventor: HUBER ERNS
IPC: B07C5/34
Filed: 1975-12-15
Abstract: A circuit automatically recognizes photographic positive prints on a production line, which have been marked at an earlier stage by means of a pencil mark so that they can be rejected. The circuit depends on the relatively high absorption of infra red radiation by the graphite pencil mark on the print, compared with the unmarked print. The prints (3) travel on a conveyor belt (2) past an infra red beam generator (1) below which is a mirror (5), so that as each print passes, the reflected beam is reduced, and any pencil mark is signified in a sudden further reduction below a given threshold. A detection circuit, consisting of a photosensitive transistor amplifications stage, integration and comparator (13), compares the reflected beam with an integrated version of the same signal.

Title: Double-walled gravimetric separator - with immersion pipe of varying dia. and rectifier surfaces
Inventor: HOELTER HEINZ
IPC: B01D21/00
Filed: 1975-12-27
Abstract: The gravimetric separator comprises an immersion pipe of varying dia. and rectifier surfaces which are mounted in an external zone between the wall of the immersion pipe and the outer wall of the separator. Contaminated liq. e.g. water used for gas scrubbing, is supplied to the separator via the immersion pipe. Where the width of the pipe is increased, the rate of flow of water is reduced, and sepn. of solid particles is improved in the sump of the separator. At the transition zone from the wide part of the pipe is an increase in surface area, converting fine particles to a state of suspension and agglomerating them so that they fall back down into the sump.

Title: Pressure die casting machine with inclined injector barrel - so melt can be poured into barrel before die closure
Inventor: STUMMER FRIEDRICH DIPL ING
IPC: B22D17/08
Filed: 1976-06-01
Abstract: The parent patent described a horizontal, cold chamber die casting machine. In this addn. the angle of inclination of the injector barrel, and its dimensions, are matched, so the melt poured into the injector barrel cannot flow via the ingate into the mould while the vol. of the barrel remains constant, i.e. before the plunger is actuated. By tilting the injector barrel on a pressure die casting machine, molten metal can be poured into the barrel while the die is still open and/or during the die closing cycle. The result is that faster casting speeds can be achieved.
