Patent DE-3834674-A1 (DE)
Title: Spray diffuser for colouring agents with different pigments
Inventor: BRUENE BERNHARD
IPC: B05B12/00
Filed: 1988-10-12
Abstract: Suitable for the most varied colour compositions and colour types is a spray diffuser in which the two-piece actuator for the colouring agent is accommodated in a housing and the air actuator for the air supply is accommodated in an auxiliary housing. The colour is guided by the hydraulic part, separated by a diaphragm from the control part, and the lock into a colour tube and the colour nozzle, where the air nozzle designed as a ring nozzle provides for reliable guidance of the colour jet. By additional air-directing nozzles arranged at an angle to this, which are supplied with directional air via the same compressed-air suppliers, the colour jet is accurately fixed and guided so that the application of specifically shaped and accurate colour spots, no matter of which composition, to a base is ensured. The actuator and air actuator are advantageously of the same design and, with nozzle computer and process control computer, ensure that colour jet and directional air are discharged at a certain time interval in such a way that the formation of residual drops on the colour nozzle is reliably eliminated as a result. The design of the spray diffuser and the allocated compressed-air and colour suppliers, the colour being continuously guided in the circuit so that it cannot be deposited, not only ensures quick and precise opening and closing of the lock but also a controlled and in fact accurately controlled transport of the colour over the entire path. <IMAGE>
Patent DE-3843860-A1 (DE)
Title: Compressor/supercharger
Inventor: BERTRAM ULRICH DIPL ING
IPC: F01C21/02
Filed: 1988-12-24
Abstract: In known rotating-piston machines, the fact that pressures of different amounts prevail in the gap spaces between the housing and the rotors results in a pressure-equalising gas stream which, under some circumstances, carries the grease charge out of the bearings. Known measures against this, namely O-rings or lip rings, cause considerable friction moments. The compressor/supercharger according to the invention therefore has the features that portions of the recesses (7) receiving the rolling-bearing outer ring, the said portions being present on both sides of the rolling bearings (5), are bypassed by means of at least one connecting channel (13). The compressor/supercharger has a longer life in comparison with those which are known and is suitable for use as an air pump. <IMAGE>

Patent DE-3909271-A1 (DE)
Title: Control device for sewing machines
Inventor: MORIN BERNARD
IPC: D05B69/18
Filed: 1989-03-21
Abstract: The three functions of pricking speed, thread cutting and lifting of the press foot of the sewing machine, which is equipped with its electronic box, are determined by the momentary state of a single variable resistor contact. A pedal joined to a connecting rod acts on the variable resistor contact in order to determine the speed. Two lateral flaps which can be swivelled on both sides of the pedal interact with position detectors which control the phases of separation of the thread and lifting of the press foot by intermediate switching of the variable resistor contact to which they are allocated. Since the functions are separated, the heel of the user can rest permanently on the floor in order to guarantee his/her balance, and this permits an upright working position which takes up less room than does a seated position.
