Title: Method and arrangement for measuring the dilatation of the eye
Inventor: FERCHER ADOLF FRIEDRICH PROF D
IPC: G01B11/16
Filed: 1981-09-01
Abstract: The laser (1) illuminates the entrance pupil of the eye via the splitter cube (2). In this process, a first reflection (3) of the cornea (4) occurs. A second reflection (5) is produced on the fundus occuli (6). These two reflections interfere in the total common overlap region, and produce there an interferogram resembling a Fresnel zone, for example at the point (7). A slit (12) is arranged there in such a way that it is at right angles to the interference fringes. The slit image thus produced is projected with the aid of the optics (13) onto a photographic film (14) which moves at right angles to the slit direction. In this way, there is exposed on the film (14) a fringe system which reproduces the temporal variation of the dilatation of the eye. <IMAGE>

Title: Fire-resistant adjusting device for a shut-off device
Inventor: BRUTON BILLY R
IPC: F16K17/38
Filed: 1981-09-29
Abstract: The invention provides a fire-resistant adjusting device for a shut-off device, which interacts with a shut-off device that is screwed thereto and is of the type having a cap, in order to form a screw chamber (66) with an external jacket (50) which supports the adjusting device housing (44) and forms a compartment having virtually no openings, in order in this way to prevent an external fire coming into direct contact with the screws or screw bolts and nuts which connect the cap (14) to the housing (12) of the shut-off device. The screw chamber (66) can also be filled with an insulating material (68). The adjusting device can have a resetting spring (80) which is connected to the adjusting device spindle (30) by means of a bearing (92) in such a manner that the winding-up and unwinding of the spring does not lead to a significant torque on the adjusting device spindle. Similarly, a diaphragm (108) in the adjusting device can be connected to the adjusting device spindle, by means of a bearing (126), in such a manner that rotation of the spindle does not impart any torque to the diaphragm. Furthermore, a stop (72, 74, 76) can be provided which limits outwards movement of the spindle under the influence of the spring, and, by means of the additional creation of a suitable sliding engagement between the diaphragm adjusting device housing and the spindle, the adjusting device housing and the diaphragm can easily be removed from the rest of the adjusting device without the line pressure having to drop. <IMAGE>

Title: Process and apparatus for producing a dental model
Inventor: ZEISER MANFRED P DR
IPC: A61C9/00
Filed: 1982-01-08
Abstract: A process and an apparatus are described for producing a dental model, in which positive reproductions of the tooth stumps prepared from modelling material are detachably fixed to a base plate by pins. In this method, a support, to which the base plate and the dental impression are fixed, is oriented on a work-table in such a manner that a sighting device points from above at a predetermined point in the dental impression, whereupon holes for the pins are drilled in the base plate from below. An essential feature is that the holes are drilled into the base plate offset by a specific extent relative to the sighting line of the sighting device. As a result of this offset between sighting line and hole direction, tilting of the support on the work-table is avoided.

Patent DE-3207987-A1 (DE)
Title: Combustion chamber pipe lining
Inventor: LEITHNER REINHARD DIPL ING DR
IPC: F22B37/14
Filed: 1982-03-05
Abstract: Combustion chamber pipe lining for forced-throughflow steam generators, in which the pipes are arranged perpendicularly or parallel to the adjacent wall in the region of the funnel and completely or partially in a screwthread-shaped manner in the region of the vertical walls. As the combustion chamber funnel pipe lining is formed from pipes of different length, there is a non-uniform heat absorption by the individual pipes, which can lead to very different temperatures in the combustion chamber walls. This disadvantage is resolved in that   a) the pipes which run perpendicularly or parallel to the adjacent wall are guided out of the wall at a point which lies in front of the beginning of evaopration even in part-load operation, b) the pipes guided out of the wall open into one or a number of mixing collectors connected one behind another and c) connection pipes lead from the mixing collector(s) to group collectors, from which pipes can be guided back into the plane of the wall and form the latter. A large part of the non-uniform heat absorption in the combustion chamber funnel is compensated by the mixing in the mixing collector. m

Title: Signalling light with a built-in photo-electric switch and a method for its operation
Inventor: SEKANINA CLEMENS ALIOT
IPC: H05B41/34
Filed: 1982-04-23
Abstract: The flashlight has a built-in photo-electric switch (DS) whose switch (S1) is always open when the flashlamp (BL) is illuminated. If two or more flashlights of the same type are operated simultaneously, the signal frequency of the control signals (t1, t2) is related to the mains frequency of the supply voltage of the flashlights, which is used as a frequency standard. This prevents the light surging effect occurring because of different lighting periods of the flashlamps. <IMAGE>

Title: Cassette tape-recording apparatus
Inventor: OISHI KENGO
IPC: G11B15/087
Filed: 1982-07-01
Abstract: A cassette tape-recording apparatus has a device in order to record differently coded address signals onto a magnetic recording tape; a further device searches the tape during playback for a predetermined address signal. Before the recording of a piece of information, first of all an address signal which has been selected according to the type of information to be recorded is recorded on to the recording tape; the piece of information is recorded after this address signal. When the code of the address signal is entered upon playback, the recording tape is transported at relatively high search speed; when one of the address signals having the entered code is recorded, the transport speed of the tape is reduced to the playback speed in order to play back the piece of information after the address signal. When the playback of the information has been completed and the next address signal is recorded, the transporting speed of the tape is changed again to the search speed, in order to determine the next address signal having the desired code. Consequently, all pieces of information of the desired type, according to choice, are played back. In the case of such a cassette tape-recording apparatus, a circuit arrangement is provided in order to prevent operation of the sound-output circuit of the cassette tape-recording apparatus during searching for the entered address signal; this circuit arrangement on the other hand permits operation of the sound-output circuit during playback of the recorded items of information.

Title: Filter unit and process for the purification of hot untreated gases
Inventor: WITTENMEIER FRITZ
IPC: B01D53/08
Filed: 1983-02-18
Abstract: A filter unit and a process are described for the direct removal of solids, aerosols and pollutant gases from hot untreated gas by means of a plurality of filter chambers for receiving granular filter material, which can be fed in through, in each case, one upper feed opening and can be discharged through, in each case, one lower discharge opening having an unloading device, each chamber having an untreated gas inlet nozzle and a purified gas outlet nozzle and a transport device below the filter chambers, assigned to all filter chambers collectively, for the polluted filter material. For simplified construction and operation, and also to create a simpler possibility for the regeneration of the filter material, it is proposed that a plurality of filter chambers (13) are disposed adjacent to each other, that a further transport device (5, 6, 7, 14) for transport of the used filter material to an abrasion drum (8) is connected to the transport device (3), and that a further transport device (5, 10, 11) is connected to this drum for the return of the regenerated filter material to the feed openings (17) of the filter chambers (13). <IMAGE>

Title: Evaporator for an air/water heat pump
Inventor: RAUBE WOLFHARD
IPC: F25D21/14
Filed: 1983-02-23
Abstract: In evaporators for air/water heat pumps, it is problematical under certain operating conditions to carry away the condensate which drips during the defrosting process, without additional heating of the collecting trough. As a result of the fact that the ambient air, which is guided through the evaporator by means of a fan, is divided into two air flows arranged parallel to one another, the first air flow being guided through the evaporator and the second air flow along the bottom of the collecting trough, simple construction of the evaporator is possible. In this manner it is ensured that, with ambient temperatures which lie only slightly above freezing point, freezing of the condensate in the collecting trough is avoided, without the collecting trough having to be heated by external energy for this purpose.
