Patent DE-3327184-A1 (DE)
Title: Backwashable filter apparatus
Inventor: STEFFEN PETER
IPC: B01D29/00
Filed: 1983-07-28
Abstract: A filter apparatus has two filter elements (4, 5) arranged in a filter housing (1), one filter side of which elements is connected to an outlet (14) for the clean liquid and the other filter side of which can be connected individually to an inlet (24) for the dirty liquid via a main control means (22) formed as a three-way tap. The filter apparatus also has an auxiliary control means (28), which can be actuated at the same time as the spigot of the main control means and as a function of the position thereof and which is constructed as a shut-off valve, to connect the other filter side of one of the filter elements with the connection (33) for the dirty liquid, when this filter element is disconnected from the inlet by the main control means. In order to be able to use both filter elements simultaneously for filtering and also to be able to backwash each of the two filter elements separately, the two filter elements each have a connection, controllable by the auxiliary control means, to the dirty liquid connection, as soon as and as long as the filter element in question is disconnected from the inlet, the auxiliary control means at any one time opening only one of the connections between the filter element and the connection for the dirty liquid (Fig. 2). <IMAGE>
Patent DE-3328110-A1 (DE)
Title: Roof covering for turfing flat roofs
IPC: A01G1/00
Filed: 1983-08-04
Abstract: In the roof covering for turfing flat roofs or similar surfaces not connected to the ground, there is arranged on a ceiling-supporting structure, with or without heat insulation, a water-impermeable roof skin on which a combined protection, drainage and filter layer is arranged, which becomes the air layer owing to the high water-drainage capacity, and consequently water-vapour diffusion can occur upwards (outwards) through the roof structure. The condensation occurring in extreme weather conditions can diffuse out upwards, the heat insulation remains dry and the heat-insulating value is maintained. The water storage necessary for permanent turfing takes place in the layer of vegetation arranged above the protection, drainage and filter layer. The necessary conditions, such as water and air supply to the plants, is ensured, even in the case of low laying heights.

Title: Overhead projector operating by a reflection method
IPC: G03B21/132
Filed: 1983-08-26
Abstract: The invention relates to an overhead projector operating by the reflection method, which consists of a base plate holding the mirrored Fresnel lens, and an overhead housing, which is carried by a support arm mounted on the base plate and in which the light source and the lens are accommodated, over which a deflecting mirror is arranged which can be pivoted about a joint and simultaneously serves as lens cover. It is the object of the invention to configure the overhead projector for small sizes of original and operating by the reflection method, in such a way that the previous optical disadvantages and the disadvantages occurring due to the relatively large size of mirror are quite decisively reduced. This object is achieved due to the fact that the light source is arranged on the side of the lens averted from the joint of the deflecting mirror, and that in the folded-down state the deflecting mirror or the holder of the deflecting mirror reaches beyond the light source.

Title: Method for treating fetching-in processes in the area of rail brakes in down-hill systems
Inventor: HOERDER ALEXANDER DIPL ING
IPC: B61J3/02
Filed: 1983-10-06
Abstract: If a section (follower) approaches a section ahead which is still treated in a brake, the brake (B) is not opened in advance by the follower as was previously customary with the actuation of a track switching means (K1) located at a relatively large distance from the brake. Instead, until the section ahead reaches the predetermined release speed it continues to be braked as long as is acceptable. However, for the brake control the actual advancing speed (VACT) of the section ahead is then no longer taken into consideration but rather an advancing speed (VADV) which is updated computationally. The admissible clearing time (tR) for the brake by the section ahead is composed from a brake time (tB) and a time span (tL) in which the section ahead leaves the brake which is already released. The sum of the two times is determined by the running time (tN) of the follower from the track switching means (K1) to a predeterminable location, from where a conflict-free braking of the follower is still possible. This location can be permanently predetermined or varied from case to case according to the principle of braking with the last axle. By means of the invention, the respective section ahead is brought as close as possible to the running-out speed, predetermined for said section, out of the brake. As a result, the so-called ...

Title: Afterburner for existing oil and gas heating plants with a fan
Inventor: BROZIO GERARD
IPC: F23C3/00
Filed: 1983-12-24
Abstract: The afterburner consists of three main parts, the sections, and in the embodiment example has a round shape (circle). It is provided with guide sections which are welded, screwed or riveted. Furthermore, it has a partial frame which is firmly connected after alignment. A hot zone in the burner space is produced by means of the afterburner. A hot zone which causes even fuel particles which are difficult to ignite to combustion. The great advantage consists in that little fuel is required to produce the desired heat. Furthermore, because of the afterburning, less polluting material is discharged to the atmosphere. Since less fuel is burnt, and better, this invention should especially please those who have older multifuel heating plants, since according to the invention these can be brought to the efficiency of the most modern plants without great investment being necessary. After installation of the afterburner, a smaller nozzle should be fitted, since more heat is liberated by the afterburning.

Title: Disposal of domestic refuse in conjunction with clinker production
Inventor: GRIGEL WOLFGANG DR
IPC: C04B7/44
Filed: 1985-07-08
Abstract: The landfill-free disposal of domestic refuse can be combined with the production of cement clinker in a rotary kiln, if the refuse, preferably treated by air classification, is charged at special points of the rotary kiln (1). The predominantly combustible organic fraction (17) is to be fed to the sintering zone, because polychlorinated hydrocarbons are also decomposed in this hottest region, while the predominantly inorganic fraction is to be added to the kiln inlet (16), where a very homogeneous distribution in the clinker can proceed due to the long residence time. Instead of sorting, a pyrolysis can also effect the separation of the refuse, the pyrolysis residue having to be fed at the kiln inlet and the pyrolysis gases having to be fed to the furnace near the burner. <IMAGE>

IPC: B23D33/08
Filed: 1985-09-27
Abstract: The invention relates to a hold-down device for shears, in particular billet shears with crank or eccentric drive for separating bar stock and sections. A functionally reliable solution for actuating the hold-down device is to be achieved by the invention with little cost in terms of material and production. The object of the invention is therefore to design the drive of the hold-down slide (3) in such a way that a small amount of travel is sufficient to clamp the same, and during the cutting the clamping wedge (7) is held in its position without great retaining force - if possible in a self-locking manner - and at the same time positive release of the clamping wedge (7) after the cut is guaranteed. According to the invention this is achieved in that the hold-down slide (3) is connected via a two-sided lever to a piston/cylinder unit (4) operable by a pressure medium, and between frame and hold-down slide (3) a stepped clamping wedge (7) operable by a further piston/cylinder unit (9) is mounted displaceably in the horizontal direction, which clamping wedge (7) is in turn in operative connection with a hydraulic damping and release device (10) - Fig. 1. <IMAGE>
