Title: Process and apparatus for flue gas cleaning for an oil-burning plant and for preheating the oil fed to the burner of the oil-burning plant
Inventor: HELLWIG KARL-RUEDIGER
IPC: F23K5/20
Filed: 1983-05-03
Abstract: To reduce the emission of pollutant gases from oil-burning plants, the flue gases are cooled down by the oil to be burned until condensation occurs. Besides making additional use of the heat content of the flue gases, the combustion of the low-viscosity oil is effected with a higher efficiency than with unheated oil. Building the heat exchanger into the flue entails only a small amount of expenditure which is paid back in less than a year by the savings on heating oil.

Patent DE-3406299-A1 (DE)
Title: Base for a seat or a bed
Inventor: FRITSCH ALOIS
IPC: A47C23/06
Filed: 1984-02-22
Abstract: The base has a relatively large number of slats (2) (the end of such a slat is visible in Figure 4). Assigned to each slat (2) are two elastic abutments (3) which exert forces which act on the slat (2) in the longitudinal direction thereof and attempt to bend the slat (2) upwards. The abutments (3) assigned to a slat (2) are connected to one another by a tension element (16) which is variable in length. Due to the elastic abutment (3), the elastic restoring force does not or does not completely have to be raised by the slat material. Unloaded slats are also pressed back into their desired curvature even after prolonged usage, such that material fatigue does not result in permanent deformation of the slats (2). <IMAGE>
Patent DE-3409002-A1 (DE)
Title: Method and device for placing pneumatic stowing with hydraulic support assemblies
Inventor: PAWELSKI LUDWIG
IPC: E21D23/04
Filed: 1984-03-12
Abstract: During the placing of pneumatic stowing in underground coal-mining faces equipped with hydraulic support assemblies, in particular in thick seams, sloping of the pneumatic stowing already placed is largely prevented owing to the fact that the pneumatic stowing is placed only after the support assemblies are pulled forward twice without carrying the stowing wall with them and then first of all from the floor up to about half the seam thickness and only then up to below the roof after the stowing wall is moved up. To this end, the support assemblies have a roof bar whose area projecting to the rear is at least twice the length of the degree of advance of the support assemblies. The stowing wall, which approximately corresponds to the width of the support assembly, is designed so that it can pivot and be locked approximately in the perpendicular to the stratification. It can be displaced in the advancing direction by pressure-medium cylinders independently of the roof bar itself. <IMAGE>

Title: Process for thermal joining of two plastics parts
Inventor: SAENGER WERNER
IPC: B29C63/18
Filed: 1984-11-16
Abstract: In order thermally to join a first plastics part (7) consisting of a plastic which is dimensionally stable when the temperature is increased up to a material-dependent limiting temperature, for example polytetrafluoroethylene, to a second plastics part (8) at adjacent contact surfaces, a plastic is used, for the second plastics part (8), whose softening or melting point lies below the limiting temperature of the first plastics part and which, when the softening or melting point is exceeded, assumes a state in which it can thermally join to the plastic of the first plastics part. The two plastics parts (7, 8) are heated through the first plastics part (7) in such a manner that a temperature gradient results in which the temperature in the first plastics part (7) remains below its limiting temperature and that zone (9) of the second plastics part (8) which adjoins the contact surface reaches a temperature exceeding its softening or melting point, whereas the temperature in the rest of the second plastics part (8) remains below the softening or melting point. <IMAGE>

After this layer of mortar has set, the moisture-tight sheet is laid on the rough surface of this layer and, finally, the remaining slot space is filled with concrete or the like, while compressing and compacting.
Patent DE-3510318-A1 (DE)
Title: Earth-bearing greening mats for surfaces with more than 45 DEG inclination
Inventor: DOSE GEORG
IPC: A01G9/02
Filed: 1985-03-22
Abstract: The mats serve for shaping, greening and insulating, in particular with non-climbing plants, building surfaces as well as, in varied form with two visible sides, as room dividers for inside and outside.   Strips of fabric (e.g. made of glass fibres) are coated, folded and sewn together above one another. The seams run vertically on the mounted mat, the folded strips (= channels) horizontally. The coating is watertight, weather-resistant and plant-neutral, if possible also fire-retardant, if required coloured. The coating leaves parts open in the lower region of the visible side(s) of the channels, for watering and aeration of the earth fillings and is at the same time a shaping means. Mounting takes place along the seams by e.g. nailing onto laths or hooking on if eyes are included in the mats. The mats can be distributed as flat sections or rolled, either in the direction of the channels or perpendicular thereto. <IMAGE>
