Patent DE-3418324-A1 (DE)
Title: Method of laying underground, thermally insulated pipe systems with pronounced directional changes, e.g. when laying district heating pipes in an angular manner at a road intersection
Inventor: PEDERSEN HANS NOERGAARD
IPC: F24D3/10
Filed: 1984-05-17
Abstract: When laying thermally insulated pipes underground, conventional pipe bends are replaced by curved pipe lengths with a substantially enlarged radius of curvature, which has a minimum value in accordance with the pipe size, in which arrangement the pipe bend itself, interacting with the earth, can absorb the expansion and contraction forces of the pipes caused by the temperature fluctuations. It has been found that this minimum value is so small that there is sufficient space, e.g. at a road instersection, to be able to bend a medium-duty pipe by 90 DEG  without using a sharp pipe bend. A self-compensating bend is obtained, in which case special components, such as axial compensators, ground anchors and bends filled with insulating material in a flexible manner, are dispensed with in an extended pipe system. Bends can be realised by curved standard pipes or by assembling straight standard pipe elements of small directional change per converging point.

Title: Filter for a smokable article
Inventor: PAULSEN KURT DIPL PHYS DR
IPC: A24D3/04
Filed: 1984-08-03
Abstract: A filter for a smokable article, in particular for a cigarette, has a first segment facing the tobacco rod and having an inlet nozzle, an adjoining void taking up more than 70 % of the first fragment, and an outlet opening; this void is sealed by a gas-impermeable material. The outer wall or the wrapping paper of the first segment is gas-impermeable. The first segment is adjoined by a second segment which is formed by an empty chamber bounded by perforated wrapping paper. The second segment is adjoined by a third segment having a central void with an inlet nozzle or outlet nozzle and with a layer of filter material surrounding the central void in annular form. The outer wall of the central void of the third segment and the outer wall of the layer of filter material are gas-impermeable, while the two end faces of the third segment are gas-permeable. The filter is enveloped on the outside by a porous covering paper. As a result of this special construction and the sizing of the material, the degree of ventilation and the efficiency of the filter increase with an increase in puffing volume.

Title: Locking means for chimney-lining parts
Inventor: TEERI NIILO HEIKKI PROF
IPC: E04F17/02
Filed: 1984-10-09
Abstract: The invention relates to a means for locking lining parts used for lining chimneys, which locking means facilitates installation of the lining, prevents the lining parts from mutually detaching of their own accord, and thus renders the result of installation work more reliable for operation over a long period of time. Moreover, the locking means permits installation of the lining without a lateral penetration of the chimney being necessary when introducing the conical element (3), used for fixing in the masonry, into said chimney. The invention is characterised in that the flexible tube (2) used for the lining is locked to the individual parts of the system by means of metal locking sheets (5, 6, 10, 12), the tube either being pushed onto (4) the connecting piece of the relevant part or pushed into (7) said connecting piece. When in the installed state, the individual parts of the lining thus form together a single, stable unit (Figures 2, 5, 6). <IMAGE>
Patent DE-3439193-A1 (DE)
Title: Nozzle with cover connected in front of it
Inventor: KETTERER KLAUS DIPL ING
IPC: B05B15/02
Filed: 1984-10-26
Abstract: Water nozzles, which because of their field of application tend to become blocked, are kept free, even under unfavourable conditions, by a cover being arranged in front of the nozzle opening. This cover has a passage opening which has a larger diameter than the nozzle opening itself. If this cover is constructed in the form of a sleeve, a channel which has outlet openings at the end and the conically outwardly extending passage opening at the opposite end is formed between sleeve and oblique portion of the nozzle housing. In this way, a cavity is formed between the two components, the said cavity receiving any stone dust which penetrates and ensuring that the said dust is caught by the emerging water jet and rinsed away. The nozzle is thus effectively prevented from becoming blocked. <IMAGE>

Title: Water purification device having a fan
Inventor: STOG WILHELM
IPC: C02F3/06
Filed: 1984-12-28
Abstract: To regenerate water, for example industrial wastewater, a device is used which is equipped with a support framework which is deposited in the clarification tank, that is on a pipe laid there in a fixed manner. This pipe, which is connected to a fan arranged outside the clarification tank, conducts the necessary air inside which then passes from the pipe flowing out into an air/water mixer, which is designed as a surrounding tube, having a water suction zone. Here an intensive mixing with the wastewater to be purified takes place and the air bubbles are divided into very fine air bubbles which are then forced via a compressor into a contact zone. The contact zone is provided with a long pipe which is laid at a slight incline to the water surface, which pipe has an inner air-permeable and an outer air-impermeable wall. In this manner, a long residence time of the air bubbles in the wastewater is achieved and thus a good incorporation of the atmospheric oxygen. In this manner, an optimal regeneration is ensured. <IMAGE>

Title: Device for guiding and spreading out a web of material
Inventor: LOBMAIER FRANZ DIPL ING
IPC: B65H23/038
Filed: 1985-02-28
Abstract: The invention relates to a device for guiding and spreading out a travelling web of material having at least one edge sensor which is connected to a correction device which registers the web of material by frictional contact and has at least one correction roller which together with a strip-out device which has at least two strip-out rollers held in lateral supports and is connected upstream of the correction device in the travel direction of the web of material, forms a modular unit, the modular unit being mounted so that, during the travel of the web of material, it is movable counter to the travel direction for reset. In known devices of this kind, the strip-out rollers are not moved transversely to the web travel direction, causing high distortion of the web of material and requiring an additional travel force for the web of material. According to the invention this is avoided in that the spreading-out rollers in the modular unit are mounted so as to be movable transverse to the web travel direction and counter to the connection device.

Title: Working table
Inventor: LARSEN MOGENS DROST
IPC: B25H1/12
Filed: 1985-06-04
Abstract: In a working table for use in the mounting of electronic or precision mechanics components, having a conveyor (21) which intermittently carries bowls (10) with the components in and past a collecting position, the bowls are round, and each bowl is mounted on the conveyor in such a way that it can oscillate about a horizontal axis (16) which is parallel to the conveyor. Furthermore, each bowl can rotate about its own axis (14) and, while the conveyor is moving, the lower edge of the bowl rests against a table top (22) in such a way that the bowl rotates. A number of radial channels (23) are formed in the base (11) of the bowl and have a width which corresponds to the width of the components. While the bowl rotates, the components gradually slide down the channels and, in the collecting position, two components will always be accessible in a comfortable collecting position, regardless of whether the component is to be mounted horizontally or vertically. <IMAGE>

Patent DE-3522820-A1 (DE)
Title: Process and device for reducing the pollutant emissions of combustion plants
IPC: B01D53/60
Filed: 1985-06-26
Abstract: The combustion zone of a combustion plant operated with gaseous, liquid or solid process fuels, for example a steam boiler, has a filter zone using solid fuel as a filter material provided downstream. This expediently degassed solid fuel acts both as a mechanical filter, that is it retains solid flue gas particles, but also has a highly reducing action, that is the nitrogen oxides formed in the combustion zone are very substantially decomposed in the filter zone. If lime is added to this filter material, sulphur dioxide is also almost completely bound. The exhaust gases downstream of the filter zone are subjected to afterburning with feed of secondary air. The filter fuel is likewise burnt when its activity is no longer sufficient and is continuously replaced by new filter fuel. Both filter maintenance and filter regeneration are thus dispensed with, and filter costs are also avoided since the calorific value of the filter material is also fully exploited. An embodiment of a combustion plant operated with solid process fuel is described.

Title: Configuration for forced turning-off of a thyristor
Inventor: KRIENKE ANDREAS
IPC: H03K17/732
Filed: 1985-08-10
Abstract: The requirement is to optimise a configuration for forced turning-off of a thyristor by means of a commutation circuit, which contains a turn-off semiconductor which is connected in parallel in the same direction, and which can be switched off, and a capacitor which is connected in series, and which can be loaded from a voltage source. This should be achieved with low recharging power, but nevertheless shorter commutation time. According to the invention, the way this is achieved is that the commutation circuit is constructed from two stages which relieve each other, a main stage (II) and a supplementary stage (I), in two different voltage levels (UC1 and UC2). The main stage (II) is at the higher voltage level (UC2), and is provided for the fastest possible current transfer into the turn-off circuit via the turn-off semiconductor (V2), and the supplementary stage (I) at the lower voltage level (UC1) "releases" the thyristor (V1) during its hold-off interval. <IMAGE>

Patent DE-3608732-A1 (DE)
Inventor: WUEST BURKHARD
IPC: E02D13/02
Filed: 1986-03-15
Abstract: An apparatus for inserting and/or withdrawing a construction profile in the form of trench sheeting, sheet-piling elements or the like into or out of the ground, having an oscillatory system which is designed as a vibratory hammer and consists of an exciter which is mounted in a housing via spring elements and can be vibrationally connected by means of a clamping device to the construction profile to be moved. According to the invention: a) the clamping device (3) is mechanically connected to two impact surfaces (7, 8) which are at a distance apart, and the housing (2) is fastened so as to be displaceable relative to the impact surfaces (7, 8); b) the distance between the percussive surfaces of the exciter and the impact surfaces (7, 8) can be limited by adjustable stops (13, 14), and c) the exciter (1) can be restrained with the clamping device (3), and the housing (2) is designed in such a way that it can be acted upon by a variable static force in the respective direction of movement of the construction profile (4). The adjustable stops (13, 14) for limiting the spring travel of the springs which are active between the exciter (1) and its housing (2) each consist of a screw bolt which is provided with lock-nuts. Apart from the function as a vibrator known per se, the apparatus can be used as a hammer or vibrator, depending on how this is called for by the ground conditions, under constant clamping and thus guidance of the construction profile in the pulling or thrust direction while maintaining a statically acting force. The adjustable stops enable the system to be optimised, and the damping plates provide for a corresponding reduction in wear and noise. <IMAGE>

Title: Crate, especially a fish crate, which is shaped to be stackable, and a lid for use together with a crate of this type
Inventor: MORTENSEN JOHANNES TH
IPC: B65D81/26
Filed: 1986-06-07
Abstract: A crate, especially a fish crate, consists of a base (1) and side walls (3 and 4) which project upwards from the base and are connected to one another, and drainage holes for leading off liquid from inside the crate are arranged at the transition between the side walls and the base. These drainage holes have the shape of a gap (7) which communicates with a vertical channel (6) formed in the side walls. Together with the gap (7), the channels (6) are shaped such that liquid coming from a channel in one crate in a stack of crates can flow on directly in a channel of any crate below it. Liquid from one crate is thus prevented from flowing down either into the contents of crates below it in the same stack or into crates of an abutting stack, as a result of which the possibility of storing iced fish under identical conditions, irrespective of where they are located in the stack, is improved considerably. <IMAGE>
