Title: Dental model andd production method therefor
Inventor: ZEISER MANFRED P DR
IPC: A61C9/00
Filed: 1984-03-28
Abstract: The invention describes a dental model and a method of producing a dental model, in which the dental stumps are retained by pins on a base plate which are aligned transversely to the direction of the tooth axis and are held in coaxial receptacles in two wall sections of the base arranged at a distance from one another. In contrast to the state of the art in which the pins are aligned in the direction of the tooth axis the pins can now be removed individually without any change in the position of the dental model arch relative to the base.

Title: Environment-friendly coal-fired power station with a great reduction in harmful substances
Inventor: UHRIG WALTER
IPC: F22B3/00
Filed: 1984-07-16
Abstract: The invention comprises important advice for the conversion of existing coal-fired power stations which pose a great threat to the environment. These innovations are to ensure that a much higher temperature arises in the furnace interior, which does not even allow the environmental poisons arising in previous furnaces to arise. In addition to the conversion of existing intact coal-fired power stations, there is also the possibility of building new installations according to this system. The invention could be described as an environment-friendly coal-fired power station with a great reduction in harmful substances. The heating coil filled with thermo-oil in the furnace interior, the complete chamotte lining, which is also extended to the chimney, and the fluidised-bed part are to prevent the occurrence of oxidation substances and consequently contribute to the environment-friendliness.
Patent DE-3427584-A1 (DE)
Title: Injector appliance
Inventor: EISELE FRANZ
IPC: B01F7/02
Filed: 1984-07-26
Abstract: An injector appliance for sparging liquids is described. A paddle wheel mounted below the liquid level in a cup-shaped mixing chamber is actuated, on its rear side, by gas. The liquid is drawn in axially in the centre of the rotor, is radially accelerated by the rotation of the rotor, is mixed with the gas drawn in by the injector effect in the outer region of the wheel, is deflected through the mixing chamber and is re-expelled in an approximately radial direction so as to envelop the suction flow. Various designs of the mixing chamber are possible. In each case, however, there is no continuous separating wall between the suction flow and the discharge flow.

Patent DE-3513809-A1 (DE)
Inventor: WEBER GUENTER DR
IPC: C01B17/05
Filed: 1985-04-17
Abstract: A process is disclosed for the cleaning of a clogged packed column. The packed column is utilized for gas cleaning in a scrubbing operation carried out with a scrubbing medium, and becomes plugged by deposits which form during operation. In order to be able to effectively and economically break up these deposits, the packed column is flooded, e.g., with a scrubbing medium, wherein the flooding fluid has a specific gravity greater than that of the particles of packing material. During the flooding of the packing, the deposits are broken up by flotation of the packing material. Preferably, the packed column can thus be utilized in scrubbing out H2S in an oxidative scrubbing process in which sulfur deposits form.

Abstract: PCT No. PCT/DE86/00207 Sec. 371 Date Mar. 9, 1987 Sec. 102(e) Date Mar. 9, 1987 PCT Filed May 15, 1986 PCT Pub. No. WO86/06777 PCT Pub. Date Nov. 20, 1986.A concrete-reinforcement bar, especially a tension bar, provided with hot-rolled, helically-arranged ribs, which are located on two mutually-facing sides of the periphery of the bar and form parts of a thread. The ribs of the thread extend over roughly a third of the periphery of the bar and are inclined toward one another with their front faces which merge into the smooth bar surface of the core cross section. In order to improve the fatigue strength, and mechanical strength, and to simplify the production of the threaded bars and reduce the required tolerances, the cross-section of the bar has a regular, smooth undulating profile in an axial plane in the region of each rib (2); the wave-shaped tops of the ribs and the valleys between the ribs thus form cavities in the otherwise circular core cross-section. The cavities penetrate into the core cross-section only at localized points.

Title: Scrubbing liquid for scrubbing SO2 and NOx from flue gases downstream of fossil power stations
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/34
Filed: 1985-05-29
Abstract: The main application P 3518974.6 relates to a scrubbing liquid which is chemically treated for separating out SO2 and NOx from the flue gases downstream of power stations and other fossil combustion plants. It has now been found that laughing gas can form during the contacting of a scrubbing liquid having a pH above 7. In order to establish this, according to the invention it is proposed that the scrubbing liquid is used at a pH below 7 to avoid laughing gas and above 7 if the preparation of laughing gas is desired.

The invention further relates to a device with which the aforementioned subsequent external insulation can be produced in an extremely economical manner.
Patent DE-3539024-A1 (DE)
Title: Switch
Inventor: GANSCHOW HARTMUT
IPC: G08B13/16
Filed: 1985-11-02
Abstract: Light switches designed as automatic dimmers, which react inductively to being pressed, are known. So-called passive infra-red light switches, which respond to the heat radiation of a person going through their field of vision, are also known. For these light switches, sensors which have a field of vision of up to 180 DEG  and can detect a person at a distance of up to 15 m, have been developed. If such switches are installed, for example, on the staircase of a high-rise building, two such switches are required on each floor of the building. To create a switch which is not only simple to manufacture and fit, but also needs to be present only once even for a closed system (space) to carry out specified desired switching procedures, the invention proposes that it has a sensor which is sensitive to pressure in the infrasonic range, and to which electronics in the form of an amplifier (2), a frequency pass filter (3), and a comparator (4) are connected in series, to form a signal depending on changes of pressure, which is fed to a switching element. The invention is based on the central idea of exploiting a quite different physical principle from the mechanically inductive or passively infra-red techniques used until now, namely so-called infrasound (Fig.). <IMAGE>

Title: Scissor-type lifting platform
Inventor: FUCHS GERHARD
IPC: B66F7/08
Filed: 1986-02-13
Abstract: In a scissor-type lifting platform (1), in particular for motor vehicles, two lifting tables (2) serving as ramp rails are provided. In each case two scissor spars connected to lifting cylinders act on the lifting tables (2). The scissor spars (3) of each side each have a movable bearing and a fixed bearing at their top and bottom ends. On the base side, the fixed bearings (5) and the movable bearings (6) of the scissor-spar pairs of each side are connected to one another by yokes (7) on which lifting cylinders arranged in between act. Also arranged next to the lifting cylinder are additional units such as a hydraulic pump (17) and, in the case of several cylinders, a filling-capacity distributor (18) and the like, so that a compact drive unit is formed. The drive unit is accommodated inside a flat base box (14). In addition to the main lifting cylinder or cylinders (9) between the yokes (7), a preferred embodiment also provides for at least one auxiliary lifting cylinder (25) with a smaller working stroke compared with the main lifting cylinder. The auxiliary lifting cylinder acts in the lowered position and up to a portion of the lifting height of the lifting tables in the case of the movable-bearing yoke (7). Thus, the initial movement of the lifting platform, in the course of which an especially high force is necessary on account of the unfavourable lifting ratios, is assisted by the auxiliary cylinder. The main lifting cylinder can thereby have a smaller type of construction. <IMAGE>
