Patent DE-3706857-A1 (DE)
Title: Parts conveyor
Inventor: NAPIERSKI REINHARD
IPC: B65G27/14
Filed: 1987-03-04
Abstract: The parts conveyor for transporting individual parts comprises a piston-cylinder unit which can be actuated by a pressure medium and one part of which is stationary and the other part of which engages with a conveying trough. The stationary parts are the housing (10) and a cover (12), which hold the valve block (14). The moving parts are an angle piece (16), which is guided with its guide rods (18) in the housing (10). A control rod (26), on which are mounted two sealing mushrooms (28 and 30) and two compression springs (32 and 34), is mounted in the valve block (14). A nut (36), which is screwed to the piston (38), is movably mounted between the two compression springs (32 and 34). The return stroke movement is initiated by means of the opened valve mushroom (28), as a result of which the nut (36) strikes against the spring (34) and thus closes the valve mushroom (28) and opens the valve mushroom (30). By this means, the conveying stroke is initiated, which is controlled by a valve-piston-cylinder unit in such a manner that the outwards-flowing pressure medium is at first throttled and is released when the pressure drops. <IMAGE>

Title: Apparatus for delivering cleaned bottles or similar containers from the container cells of continuously circulating conveying cages to a bottle-removal conveyor for cleaning machines
Inventor: ELSNER PAUL
IPC: B08B9/44
Filed: 1987-05-14
Abstract: Apparatus for delivering cleaned bottles or similar containers for cleaning machines, with which the cleaned bottles emerging from the conveying cages of the machine are taken over by container holders circulating on chains, are set down on a delivery table and then delivered to a removing conveyor by means of pushing means. In the process, malfunctions arise, in particular at high speeds, during both taking-over and during lowering and setting-down of the bottles. The novel apparatus avoids such malfunctions while, at the same time, providing increased efficiency. This is achieved by means of container holders in the form of circulating cages (13) having holding cells (15) which serve at the same time, as pushing means and which, for the purpose of taking over containers, first of all circulate in the transport direction (45) of the conveying cages (3) and, both during taking-over, lowering and setting-down of the bottles (1) and during pushing of the rows (9) of bottles onto the removing conveyor (10), are guided such that, during the respective running of the circulating chains (28), which takes place on a trigonal circulating path, the holding cells (15) which surround protectively on all sides the body of the bottles which they have received in each case assume a permanently perpendicular position; cf. Figure 1. <IMAGE>

Patent DE-3718818-A1 (DE)
Inventor: PARDIKES DENNIS
IPC: C08F2/00
Filed: 1987-06-05
Abstract: A polymer activation system provides a variable rate, preferably continuous output of activated liquid polymer. The water and the polymer are introduced into a mixing loop (24) having a premixing manifold (26) containing a static mixer. The polymer is then blended and activated by a mechanical agitation and partially fed back into the mixing loop, to provide a desired level of polymer activation which is delivered at a desired flow rate. The resulting process includes the four steps of: pre-mixing, blending, recycling, and a final relaxation. Once the desired level of activation is selected, the system automatically maintains that level in response to changes in the output rate. The system also provides capabilities for selecting various levels of polymer concentration. <IMAGE>

Patent DE-3720931-A1 (DE)
Title: Combustion process, especially for used oil
Inventor: REICHART JOHANNES
IPC: F23J15/02
Filed: 1987-06-25
Abstract: According to the used-oil combustion process of the invention, the used oil is preheated to a temperature of less than 100@C, preferably to from 50 to 60@C, and is passed under pressure through a jet-type lance and is injected, via the orifice of the jet-type lance, into a combustion chamber. Around the jet-type lance there flows, at least over part of its length in the direction of the nozzle, a cooling compressed-air stream. At the nozzle outlet, the compressed-air stream and the used-oil jet are brought together essentially tangentially, are mixed intensively and at a distance from the nozzle outlet are ignited to form an elongated flame having a core temperature of over 1000@C. It is possible to inject additionally, into the used-oil/compressed air jet, fine granular or pulverulent combustible solids particles which may be entrained, finely dispersed, by its flow and burned together with it.
Patent DE-3724479-A1 (DE)
Title: Bending device for the individual pre-bending of osteosynthesis plates during surgery
IPC: A61B17/80
Filed: 1987-07-24
Abstract: In the osteosynthetic treatment of bone fractures there is a problem in that the plate material used must be adapted as optimally as possible to the bone, that is, it must be pre-bent. This bending process is generally carried out by the surgeon using forceps, plate benders and the like. The present invention solves this problem as follows: a readily deformable plate (e.g. one made of lead) whose dimensions correspond to those of the desired osteosynthesis plate is placed on the fracture area in the same manner as the osteosynthesis plate to be used subsequently and is adapted to the shape of the bone by manual pressure. This lead plate is then placed in a device which essentially comprises two rows of pins arranged one on top of the other. These pins make contact with the lead plate, after which the pins of each row are fixed relative to one another, for example by lateral compressive forces. The desired osteosynthesis plate is then placed between the rows of pins and pre-bent in the form of the lead plate in a suitable pressing device. In order to balance out any resilient springing-back of the osteosynthesis plate, beads and notches on the sides of the pins can engage each other in such a way that on clamping the pins laterally those pins which already project somewhat further after the contacting operation slip forward to a somewhat greater extent than their neigbouring pins (see Fig. 2). <IMAGE>

Title: Screw-type terminal with a box-shaped clamping bush
Inventor: GIEGOLD PETER
IPC: H01R4/38
Filed: 1987-07-28
Abstract: A screw-type terminal (10), used for the conductive connection of current leads for low-voltage equipment and installations, is composed of at least one screw element (11) and a pressure piece (14) assigned to the screw element, as well as of a box-shaped clamping bush (18) which consists of a multiply bent strip section and has a lower clamping wall (22), mutually opposite, upward-projecting side walls (23, 24) and a screw wall opposite the clamping wall and equipped with an internal screw thread (21) for each screw element, said screw wall being formed by the two end regions (19, 20) of the strip section, which overlap each other over the entire area of the screw wall. The screw-type terminal is characterised in that there are provided, along at least one of the bent edges located in each case closest to the two end regions (19, 20) of the strip section, slots which are open towards the lateral edges of the strip section or instead of these at least one slot-shaped recess, into which there engages - self-adhesively or adhering by additional measures or in a self-clamping manner - in each case one protruding, strip-shaped projection emerging from the facing end of the other end region of the strip section. As a result, separation of the overlapping end regions of the strip section can be prevented and thus also a spot-welded joint ... Original abstract incomplete. <IMAGE>

Title: Method for selective vibration monitoring of rotating machines
Inventor: WEIGEL MANFRED DR ING
IPC: G01H1/00
Filed: 1987-07-29
Abstract: The invention relates to a method for increasing selectivity during the investigation of vibration for diagnosis and monitoring of the mechanical state and the operational behaviour of rotating machines, in particular thermal turbo-engines on sliding bearings, with the aim of avoiding damage, early detection of damage and the avoidance of consequential damage. It is the object of the invention to take account of the previously existing possibilities of diagnosis on the design particulars of the relevant installations in general and their way of running in particular by further consideration of the vibration indicators (absolute amount and phase angle). This is accomplished according to the invention by filing in an indicator memory (1) the signal components of the various states, which components are harmonic with respect to the rotation frequency, by filing the arithmetic mean for each signal component in a reference value memory (2) and using a monitoring module (3) to determine the differential value indicator between the actual state and mean reference state, to compare it with the standard range and to signal any infringements. In addition to the indicator memory (2), a parameter memory (4) is formed which detects the associated operating parameters at the respective measuring point. A regressor 5 provides a function for predetermining the reference value. <IMAGE>
Patent DE-3735794-A1 (DE)
Title: Basin for liquid, in particular swimming pools
Inventor: ZEBINGER FRITZ
IPC: E04H4/00
Filed: 1987-10-22
Abstract: The invention relates to an adjustment structure for basins for liquids, in particular swimming pools, of metal configuration for compensating settling or even defects in the foundations, as a result of which the pool, or the overflow border of the same, can be set horizontally at any time in order that uniform overflow over the entire pool border can take place. In order to carry out this object, the upper border of the pool (8) exhibits a flange (9) which can be adjusted in sections by vertically adjustable screws (3a and 3b), with the result that an overflow which is uniform around the periphery of the pool (8) takes place into the overflow channel (2). <IMAGE>
Patent DE-3737119-A1 (DE)
Title: Short-stroke push-button switch (key)
Inventor: MOTSCH ALFONS DIPL ING
IPC: H01H13/06
Filed: 1987-11-02
Abstract: The short-stroke push-button switch described here has an elastic push-button element, in a manner known per se, which is in the form of a disc, can be pressed in in a sprung manner against a mating contact device as a contact device, and at the same time connects the poles of a circuit to one another. The novel feature is that the push-button element (1) is produced integrally with the push-button housing (2). Access to the hermetically sealed air space (26, 27) between the push-button element and the mating push-button device (13) is thus possible only by exercising sufficient force for breakage. Another novel feature is that the air pressure in the air space (opposing pressure against the switching pressure) remains virtually constant over the temperature range -30@C to +80@C as a result of a special pressure equalizing device (22, 24). The excellent progress on the short-stroke push-button switch according to the invention is, however, the reliability of switching even when the switch is pressed off-centre. Even a slight switching pressure on the edge of the push-button element (1) results in reliable switching. The reliability is based on the novel multi-point circuit which is contained in a contact support (13) and whose eight switching points (14, 15) are arranged in a circular shape around the vertical axis of the flexibly elastic contact disc (7) which is mounted on the push-button element (1), at a distance from it. The switching movement (distance between the contact disc and the switching points) can be adjusted by displacing the cylindrical contact support along the vertical axis in a moulded ring (11) which is mounted in the push-button housing. <IMAGE>

Title: Process and apparatus for reducing gas emissions from flowing, fluid media with volatile contents
Inventor: STAHN ROLF
IPC: E03F5/04
Filed: 1987-12-29
Abstract: The description has been given of a process and apparatus for reducing gas emissions from sewage with volatile constituents if the said sewage has to be channelled away at certain points over large differences in height. Such tasks arise, for example, in water management for residential areas. Until now, the sewage has been guided away in "free fall", as a result of which strong air turbulence and inclusions of bubbles in the sewage lead to considerable gas emissions with adverse effects on parts of structures (concrete corrosion) and the environment (gas imissions). In order to reduce the gas emissions, the sewage is channelled in a dammed-up manner in a vertical pipeline, the open "free fall" being eliminated, and the dammed-up discharge is effected according to the invention in that the lower end of the line is closed off by a float body or optionally by a sinker body, and discharge through the line only takes place if the float or sinker force of the closure bodies is overcome by a corresponding water level in the headwater.
