Title: Occlusal position carrier
Inventor: MARX JOACHIM
IPC: A61C13/34
Filed: 1988-03-23
Abstract: In the clinical preparatory work for a denture the occlusal position carrier permits the dentist a preliminary provisional bite-taking by using this instrument to introduce suitable impression composition into the mouth, so that the patient can close the mouth during taking an impression of the oral cavity. The shaping of the occlusal position carrier permits this to be done irrespective of whether there are still teeth remaining in the patient's mouth. Thus, this preliminary bite-taking can be done in patients having all their teeth or only some teeth left, as well as in patients without teeth. By this type of preliminary bite-taking the dentist makes it possible for the dental technician to produce a model of the mouth which can be used to produce bite plates or recording devices related to the skull coordinates. <IMAGE>

Patent DE-3826707-A1 (DE)
Inventor: SCHWEINFURTH GUSTAV
IPC: F01N1/24
Filed: 1988-08-05
Abstract: In a process for the manufacture of an exhaust silencer for motor vehicles, the advantages derived from employing mineral fiber mouldings are extensively retained while at the same time greatly reducing expenditure on shape-stabilization and transportation. To this end the silencer casing itself is divided in the meridian plane and the mineral wool is supplied and inserted directly into the original silencer casing in the form of precisely dimensioned prefabricated elements which have been impregnated with a suitable fluid, for example pretreated with synthetic resin, but not cured. This enables fast and reliable positioning of the impregnated and manually compressed prefabricated elements around the periphery of the exhaust pipe and the internal component containing the exhaust pipe inside the original silencer casing; once the silencer casing has been closed, the silencer is ready for installation. Curing, hardening or some other time consuming method of shape-stabilization is not necessary. Nevertheless, in comparison with packing the silencer casing with loose mineral wool, a more even fiber distribution is achieved, and the introduction of a specified quantity of fibers is assured through the employment of prefabricated elements, whereby the impregnation of the prefabricated elements renders them soft and pliable and thus easy to work with when placing them in position under compression.
Patent DE-3826811-A1 (DE)
Title: Drilling device
Inventor: FISCHER ARTUR PROF DR
IPC: B23B51/00
Filed: 1988-08-06
Abstract: Drilling devices for making undercut holes are known in which the drill shank is guided in a sleeve with such great clearance that the drill shank is pivotable inside the sleeve. The result of this is that the drill can deflect laterally during the drilling operation, which results in curved drill holes. In order to improve the rectilinear guidance for the drill, a sleeve enclosing the drill shank is proposed, the circumferential surface of which has an enlarged diameter towards the centre.

Title: Measuring the radioactivity of aerosols
Inventor: AUBERT JEAN-FRANCOIS DIPL ING
IPC: G01T7/06
Filed: 1988-08-27
Abstract: In measuring the radioactivity of aerosols in nuclear power stations, an air sample (1) is extracted from the exhaust air. This flows through a separating apparatus (2) in which a classification according to size of the particles contained in the air sample (1) is undertaken. After the separation has been carried out, an individual measurement is made for both materials (3, 6). While the coarse material (3) is measured in a subsequent detector (4) the fine material (6) is fed as an aerosol through a filter (7). There a non-classifying separation and the corresponding measurement take place. The particle-free air (8) then escapes into the chimney. <IMAGE>

Title: Process and apparatus for evening out discharge-water quantities from stormwater retention tanks
Inventor: STAHN ROLF
IPC: E03F5/10
Filed: 1989-01-07
Abstract: In order to achieve a quasi-stationary discharge from stormwater retention tanks, it is proposed to provide, at the level of the tank bottom, an angled-off discharge pipe which is mounted in the tank wall such that it can rotate about the pipe axis and whose outflow end opens into a discharge duct, and the inflow end of the discharge pipe is coupled, in the retaining chamber, to a float. The discharge-regulating action of this apparatus is based on the fact that, during the filling of the retention chamber, the float floats up in said chamber, consequently the discharge pipe inevitably completes a rotary movement and, therefore, the pressure level between the water level in the tank and the discharge-pipe end remains approximately constant during the entire discharging operation.
