Title: Method and device for measuring the fluorescence decay time (afterglow time) of a fluorescing substance
Inventor: FEHRENBACH GUSTAV WERNER DIPL
IPC: G01K11/32
Filed: 1986-02-21
Abstract: The subject-matter of the invention are a method and a device for measuring the fluorescence decay time of the radiation of a fluorescing substance whose fluorescence decay time depends on at least one physical magnitude. The fluorescence radiation is fed back onto the output radiation in a resonant circuit whose frequency is a measure of the physical magnitude. The fluorescence radiation is thereby fed to a photoelectric receiver whose output signals are fed after phase-sensitive rectification and integration to a voltage-controlled oscillator. The fluorescence radiation is rectified only in the decay phase in an alternating fashion sensitive to phase. The total times of the rectification sections of different length are the same in the two directions. The alternatingly rectified signals are integrated. <IMAGE>

Patent DE-3609841-A1 (DE)
Inventor: HEINTZ FRIEDER
IPC: B60R21/013
Filed: 1986-03-22
Abstract: A sensor (11) in which the inner space (13) of a housing (10) is completely filled with gas (15) and with liquid (14). The gas (15) and the liquid (14) must not react chemically with one another or dissolve in one another, so that as sharp and precise an interface is created between the two media. When the housing (10) is diverted as a result of tilting or by a transverse acceleration, the reflective behaviour of an optical beam on the interface is modified. As a result, a control signal is generated which releases the passenger protection devices of a motor vehicle. With the aid of a single sensor both the position angle and transverse acceleration can be determined either individually or together.

Title: Separator for separating materials of different densities
Inventor: KOSLOWSKI KARL
IPC: B04B1/14
Filed: 1986-08-23
Abstract: In the known separators for separating materials of different densities, whose centrifuge drum consists of a separating vessel on whose circumference at least one discharge opening for the discharge of separated, heavy materials is arranged, which discharge opening is opened and closed by an annular slide which is located on the outside, the annular slide is of single-component design. A slide of this kind is not only relatively expensive to produce but it is also difficult to centre precisely on the separator. Also, it is not easy to fit and remove an annular slide of this kind. However, according to the invention, these difficulties are easily eliminated in that the annular slide (7) is of two-component design, the two parts (15, 16) being detachably connected to one another by means of a locking device (17). <IMAGE>

Patent DE-3639122-A1 (DE)
Title: Pump arrangement
Inventor: HEISLER KURT
IPC: B67D7/70
Filed: 1986-11-15
Abstract: The invention relates to a pump arrangement with a plurality of pumps for the delivery of variable quantities of fluid, particularly lubricant, to the lubrication points of an internal combustion engine. At full delivery, all the pumps take in lubricating oil from a tank, the pumps in this case being connected in parallel, and the said lubricating oil is delivered under pressure to the lubrication points. In the case of partial delivery, individual pumps can be connected in series. This is accomplished by the use of switching valves to establish connection between the delivery side of one pump and the inlet side of another pump so that lubricant which is already under the delivery pressure required at the lubrication points enters the second pump on the inlet side. In the case of pumps with the same displacement, the delivery side of the first pump can simultaneously be separated from the delivery line leading to the lubrication points. The inlet side of the second pump is likewise separated from the lubricant tank. The advantage is that, in the case of partial delivery, lower losses occur with this pump circuit arrangement than would be the case if, in the case of partial delivery, the delivery side of the unused pump were merely connected to the return. <IMAGE>

Title: Device for cleaning press rolls on sheet-processing machines
Inventor: FREISTEDT REINHOLD
IPC: B41F35/00
Filed: 1987-01-10
Abstract: The device for cleaning press rolls is used in independent press systems or in machines with integrated single-sheet pressing by press rolls. The aim of the invention is to prevent damage to the folded sheets by paper waste, that is to say paper fibres, paper residues, powder and filler proportions of the paper and also thread residues in the case of thread-sealing units, adhering to the press rolls. The object consists in cleaning these foreign bodies from the surfaces of the press rolls. According to the invention, on each press roll a scraper is arranged which extends over the entire length of said press roll and acts against the direction of rotation of the press rolls. This scraper may be designed as a brush or plate-shaped metal or non-metallic body and is arranged so as to be readjustable. The foreign bodies removed by means of the scraper are caught in a vessel so that they do not fall onto the folded sheet again. <IMAGE>

Patent DE-3711174-A1 (DE)
Title: Universal fluorescent tube installation luminaire for professionals, which can be operated with the commonly-used, already existing accumulators (storage batteries) from the electric toolrange
Inventor: BECH JAROSLAV
IPC: F21L4/02
Filed: 1987-04-02
Abstract: The invention relates to a portable installation, craft or car luminaire which is operated with a battery (mostly Ni-Cd), an extremely flat and powerful fluorescent tube, and special electronic circuitry. The advantages of the Ni-Cd battery system, the high light efficiency and the small current consumption of a fluorescent lamp are combined here for the first time by applying special electronic circuitry. This combination, in conjunction with the flat, oval shape (battery + Dulux fluorescent lamp integrated in the lamp handle) ensures that the luminaire is predestined for craft purposes in general and for vehicle construction in a very particular way. The battery is charged in the already existing charging unit or directly in the vehicle. A novel switch ensures perfect contact-making without sliding contact and offers protection against reversal of polarity. It is possible to adjust the luminaire by means of special contactless wiring. All batteries having the same shape, voltage and polarity can be used. With the aid of suitable adaptors, however, virtually any battery block of the most important electric tool manufacturers can be used as current source. By means of a special supplementary (auxiliary) beam projector, a long-range (long distance) effect is achieved to a considerable degree. The luminaire can also be operated directly from the mains by means of a ballast device.

Title: Method for automatically feeding rolls of photographic paper to a photographic printer and a device using this method
Inventor: RAUH HANS-JUERGEN DIPL CHEM DR
IPC: B65H19/12
Filed: 1987-10-15
Abstract: The invention relates to a method for automatically feeding rolls of photographic paper to a photographic printer on the hub of a reel and for introducing a respective end piece of paper from a roll into the printer. The method works as follows: the hubs (2) of the reels with the paper rolls (1) are lined up on a shaft (3) to form a stack of paper rolls. The shaft (3) is aligned with a spindle (8) which has a clamping sleeve (9) and is mounted in a paper feeding region (25) which leads to the printer (21). After the last paper winding has been drawn from a paper roll (1) which is located in the paper feeding region (25) and is to be processed in the printer (21), the hub (2) of the reel of the paper roll (1) is removed. The clamping sleeve (9) is subsequently unclamped. The stack of paper rolls is then pushed by means of a shifting device (22) on the shaft (3) by a width of the paper or the hub of the reel, and at the same time the next paper roll (1) is pushed into the paper feeding region (25) and its hub (2) over the clamping sleeve (9), whereupon the clamping sleeve (9) for fixing and rotating the hub (2) is again clamped. A description is also given of a device for carrying out the method. <IMAGE>
