Title: Coloscope with mechanical pneumatic advance
Inventor: REINHARDT LUTZ
IPC: A61M25/01
Filed: 1986-09-09
Abstract: A coloscope fitted with a mechanical pneumatic advance is no longer pushed into the area being examined, like the conventional coloscopes, but is instead drawn into the area. To this end, the coloscope is equipped with a flexible sliding pipe whose distal end contains at least one inflatable balloon. The distal end of the coloscope enveloping tube also contains at least one inflatable balloon. The sliding pipe and the coloscope form a Bowden pull device which is drawn into the area being examined, operated manually, mechanically or pneumatically in cycles and supported on the alternately inflated balloons. A program control can be used for operating the mechanical/pneumatic system.
Patent DE-3631421-A1 (DE)
Title: Method for hit determination during simulation, as well as an arrangement for carrying out the method
Inventor: HASSE WERNER
IPC: F41G3/26
Filed: 1986-09-16
Abstract: In order to simulate firing during training or in manoeuvres, a laser beam is normally transmitted from the firing device and the test is carried out to determine whether this laser beam has struck the target and, if appropriate, at what point. In the event of the target moving, a weapon lead angle is required which originates, however, from a uniform movement of the target which is not excessive. During firing with target seeking missiles, the flight time is, however, so great that the target can travel a considerable distance and can also be concealed by obstructions during this movement, so that it can no longer be struck by the missile. In order to take into account these conditions, according to the invention for firing simulation, a laser beam which is modulated with information items is sent to the target and is received there, and the direction from which the missile is coming is subsequently investigated by the target for obstructions in order accordingly to change the hit probability. Thus, in contrast to the prior art, the hit evaluation is carried out in the target rather than in the firing device. This makes possible very realistic simulation of firing with target seeking missiles, and determination of the hit probability. <IMAGE>

Title: Arrangement and method of calibrating flow measuring devices
Inventor: KOEHNLECHNER RAINER DR ING
IPC: G01F25/00
Filed: 1986-11-11
Abstract: Known calibrating arrangements use a calibrating cylinder, in which a displacement piston, which is acted upon on the rear side with compressed air, displaces the calibrating fluid, presses it via a pipe system through the flow measuring device to be tested into a storage container and thus generates a "measuring point" with a given flow. The flow can be determined from advance travel, advance speed and piston diameter. To adjust the flow, throttle and flow regulating valves are used which, as a result of their dependence on viscosity and temperature, give rise to measuring errors. The new method is intended to provide a large number of flow values per piston stroke, the viscosity and temperature of the calibrating medium being intended to have minimum error influences. In order to obtain per piston stroke many accurately adjustable viscosity-independent flow values, there is arranged on the displacement piston (2) a finely adjustable auxiliary drive (3, 4, 7, 8) which is inherently rigid and the axial movement of which is generated by means of servomotor (9). Together with the air pressure (22), an accurately programmable and rapidaly modifiable course of the flow through the test pieces (17) is made possible via the piston stroke. Viscosity-independent calibration of flow measuring devices. <IMAGE>

Title: Measuring module for petrol pumps having an electronic price calculator
Inventor: MUELLER FELIX
IPC: B67D7/26
Filed: 1986-11-27
Abstract: In order to operate a petrol pump having an electronic price calculator, measures must be taken to monitor the measured values in a comparative fashion and to continue recording even after a malfunction. To permit independent recording of the measured values, an additional measuring module (1) is connected to the electronic price calculator (16 to 20) and is driven by means of a second output of the gear adapter (6). The measuring module (1) is essentially composed of a mechanical revolution counter (22) having an electromagnetic resetting device (26, 27) and a malfunction indicator (34) which indicates a malfunction in the event of failure of the supply voltage. The revolution counter (22) is able to continue recording after the malfunction, so that any quantity of fuel which passes through the delivery system after the malfunction is also recorded. <IMAGE>

Title: Method for sheathing a coil with insulating material
Inventor: SCHROEDER HARRY
IPC: B29C45/16
Filed: 1986-12-10
Abstract: In the past, it has been known for relay coils to be extrusion coated with a plastic compound. Particularly in the case of very small material thicknesses and a small covering width between the coil flange and the sheath, there remains a risk of capillary gaps which allow the penetration of moisture and allow leakage currents to flow.   In order to ensure effective sealing and insulation of the coil winding with respect to metallic parts of a magnet system or of a contact spring set, the coil flanges (9) are provided with circumferential ribs (10) or other sections (12) of small material thickness which are melted on by the liquid plastic compound (8) during extrusion coating and are welded thereto during cooling. Such coils are preferably suitable for miniature relays for heavy-current applications. <IMAGE>
Patent DE-3703058-A1 (DE)
Title: Bed frame and bed based on modular construction system
IPC: A47C20/08
Filed: 1987-02-03
Abstract: The invention relates to a bed frame and to a bed in which the individual parts can be changed and joined together according to length and width of the frame and of the bed, and the foot part or the head part can be lifted or lowered into a desired inclined position up to 60@. In order to have a side table on one side of the bed or two side tables on the right and left of the bed which, with the head part raised, are always within easy reach at each height of the raised head part, the side table or side tables are moved forwards or backwards synchronously with the driving device of the head part, as the head part rises and descends. This results in the person lying in the bed having the side table or side tables next to them irrespective of the height at which the head part is situated in each case. The necessity to reach behind oneself with the head part raised is eliminated by this arrangement.

Title: Tracheotomy tube
Inventor: BERGMANN DIRK DIPL ING
IPC: A61M16/04
Filed: 1987-06-20
Abstract: In order to permit the wearer to speak, the conventional tracheotomy tubes can be closed by applying a finger or they can be equipped with a so-called speech valve. Both methods are uncomfortable and unhygienic to use; the speech valves offered at present moreover are not very reliable in operation because they are susceptible to contamination. In contrast, the novel tracheotomy tube is intended to be distinguished by a higher comfort on wearing, more comfortable and hygienic handling and increased operational reliability. The tracheotomy tube is provided with an inner shut-off member comprising a chamber of variable volume. This chamber, which is closed except for a supply channel, can be continuously increased in size by supplying a pressure medium until the tracheotomy tube is completely filled and hence sealed. The pressure medium is supplied through a flexible supply line and a pressure medium pump that can be operated by the patient. The tracheotomy tube is suitable for tracheotomised and laryngectomised patients and can be designed, in addition to the form described, as a cannula with windows and as internal cannula.

Title: Device for the purification of wastewaters having numerous chambers provided in at least one container
Inventor: FRISCHE RAINER DR
IPC: C02F3/00
Filed: 1988-01-13
Abstract: The device serves for purifying wastewaters (effluents) which are received in numerous chambers (14) connected in series. The individual chambers are divided by a diaphragm into a cathode space (24) and an anode space (26). The electrode spaces (24) and (26) are furnished with packings (38) on which solid cultures of the individual microorganisms can grow. When a low voltage between 1.0 and 10 V is applied, a redox potential is built up in the cathode space which rapidly offers anaerobic bacteria ideal conditions for degradation. A redox potential favourable for aerobic bacteria is likewise achieved in the anode space so that bacterial degradation can likewise rapidly proceed there under aeration with oxygen. <IMAGE>

Title: Tuyere for shaft furnaces
Inventor: GERBERSHAGEN HELMUT
IPC: C21B7/16
Filed: 1988-01-28
Abstract: The invention relates to a tuyere for shaft furnaces, in particular blast furnaces or hot-blast cupolas, with a base portion and an inner and outer shell starting from the latter, which are complemented by a front portion joining them to give a double-walled hollow body, whose cavity, formed between the inner and outer shell, carries in operation a coolant flow which is directed towards the front portion.   In order to obtain a reliably long service life of the tuyeres, the outer shell 3 is formed cylindrically or only slightly conically inside a first base pipe 5 which adjoins the base 1 and is still surrounded by the furnace wall even after advanced wear of the lining of the furnace, while a front pipe 6, which adjoins the base pipe and whose length is at least 20% of that of the base pipe 5, has a pronounced conical form. This effects not only intensification of the water cooling in the front region, but quantities of impending burden and splashing slag are diverted in the free-standing region of the conical front pipe, and growing skulls are, on contraction due to cooling, diverted to the front region, without being able to effect damage and deformation of the front pipe. <IMAGE>

Title: Arrangement for the generation of signals
Inventor: HOFFMANN ROLF DIPL ING
IPC: G01V3/08
Filed: 1988-07-15
Abstract: For the generation of signals, a magnet having alternating polarisation in one surface moves relative to a magnetic-field-sensitive element, in which a control signal is generated at the change of polarisation. The aim and the object are the avoidance of fault influences on the generation of the control signal, which are due to characteristic-value tolerances of the element and constructively caused changes in the separation between magnet and element. For this purpose, a magnetic field concentrator having two ends is used which is positioned so as to be able to pivot about an axis at right angles to the surface of the polarisation. The element is on this axis and in the vicinity of one of the ends, preferably in the region of the greatest field strength. The magnetic field concentrator can be designed as a hoop, a stamping or a rod. The invention is used in position transmitters. <IMAGE>
