Patent DE-3526212-A1 (DE)
Title: Ring-belt piston with head/skirt area(s) locally separated in the ring grooves (ring groove areas) by the ring belts
Inventor: SCHEUFLER ROLAND
IPC: F16J1/06
Filed: 1985-07-23
Abstract: A control piston is shown in which a steel body is fitted in the ring groove or the ring groove areas thereof in such a way that, preferably in the cutting of the oil groove, the external skirt/head separation can be accomplished in the casting process by local free casting of the control element,. In addition to separating the skirt from the head, partial casting around or partial exposure of the steel element has the effect, inter alia, that the steel part, for example, locally prevents the head area from expanding when heated, whilst allowing the skirt area adjacent to the steel part to enlarge unimpeded when heated. In practice this design according to the invention results in an improved control value. In addition the load bearing capacity of the piston is improved because the steel elements can be directly supported on the skirt and head part. One manufacturing step for a special slot milling of the skirt - head - as hitherto - outside the steel ring area is eliminated.

Title: Atomiser with flow controller
Inventor: GONCALVES ANTONIN
IPC: B65D83/14
Filed: 1985-08-27
Abstract: The atomiser has a ring (22) for controlling the flow, which ring is screwed to a seat (12) and is, with respect to its axial position, adjustable within a limited travel relative to said seat. In its various positions, the ring (22) limits the travel of a spray head (30) by means of which a rod (33) is actuated. The rod (33) is provided with orifices (35, 36) through which an aerosol contained in the vessel (1) can emerge. The ring (22) thus defines the cross-section of the holes (35, 36) which can move out of alignment with a sealing ring (11), so that aerosol can pass through when the head (30) is pressed in the direction of the vessel (1). The ring (22) has indices which can be brought into alignment with a mark which is not rotatable relative to the vessel (1), and define positions of the ring (22) in which calibrated flow rates can be obtained (0, minimum, maximum). …<IMAGE>…

Title: Safety vacuum valve for spray cans filled with compressed air as propellent
Inventor: FRIESE JOACHIM
IPC: F16K17/02
Filed: 1986-03-07
Abstract: In order to counteract a pressure drop - below a particular value - in a spray can filled with compressed air, a valve is required. The present valve, which is installed in the product rising pipe of the spray can, brings about the sudden blockage of the product and the propellent in the product rising pipe when a set value is reached. The spraying pressure required in each case to achieve a satisfactory spraying operation is thus guaranteed up to the blockage. The drive takes place firstly by means of the overpressure in the spray can and secondly by a counter-pressure spring which, thirdly, releases a further compression spring and its force which then causes the blockage. <IMAGE>

Title: Powder treatment unit for coating powders
Inventor: STEIGER PETER
IPC: B05B5/16
Filed: 1987-09-04
Abstract: A treatment vessel (2) contains fluidised powder and is furnished with a plurality of heaters (75, 76, 77) arranged one above the other which form different separately heatable heating zones in the treatment vessel. A powder inlet (6) of the treatment vessel is situated in the vicinity of one of these heating zones, and a powder outlet (14) is situated in a heating zone which is furthest from the heating zone lying in the vicinity of the powder inlet (6). As a result, moisture variations of the powder, which can occur due to powder newly introduced into the treatment vessel via the powder inlet, are either not transmitted or are transmitted to such a small extent to the heating zone lying at the powder outlet (14) that these variations can be rapidly eliminated. As a result, powder conditioned with respect to its moisture content can be taken off via the powder outlet (14), even if the powder does not yet have the required preset moisture value in other heating zones. <IMAGE>

Title: Prime mover
Inventor: FROEMCHEN HENRY E
IPC: F02G1/043
Filed: 1987-09-24
Abstract: In a prime mover operating on the principle of the Stirling engine, a working gas (45) is moved back and forth and periodically compressed or expanded between a first, hot space (17) whose volume can vary in accordance with the motion of a first element closing it off, and a second, cold space (26) whose volume can vary in accordance with the motion of a second element closing it off, by way of a regenerator (21) lying between the hot and cold spaces (17, 26) and connected to the latter. Heat is supplied to the working gas (45) from an external energy source (43) via a heater (12), and a change in volume of the working gas (45) serves to perform work. The heat released in a compression in the second, cold space (26) is dissipated via a cooler (30). So that such an engine can operate dependably over the long term and the working space remain hermetically sealed, the first and second elements are each formed by a diaphragm (16, 24), whose side facing away from the working gas (45) is connected in a force-fitting manner to a first (44) or second (46) fluid. <IMAGE>
