Patent DE-3722363-A1 (DE)
Title: Two-frequency diaphragm pulsator with frequency shift
Inventor: SPILLECKE VOLKMAR DIPL ING
IPC: A01J5/12
Filed: 1987-07-07
Abstract: The present invention improves a known two-frequency diaphragm pulsator to the effect that the latter is less sensitive to fluctuating rubber quality of the diaphragms, is simpler in design, saves space and is therefore less expensive. The reworking in the event of diverging rubber quality can then largely be omitted. The space which is saved permits an improved configuration of the ducts and thus a reliable pulse curve. According to the invention, the second valve has been replaced by a hollow valve which is connected to a diaphragm and has its own sealing seat. The space surrounding the hollow valve is connected to the vacuum, and is separated from the alternating pressure chamber by a diaphragm or a piston. Application in milking systems. <IMAGE>

Title: Gas stove with at least one cooking-area burner below a glass-ceramic plate
Inventor: KASELOW DIETMAR G
IPC: F24C3/12
Filed: 1987-09-25
Abstract: Gas stove with at least one cooking-area burner which is covered by a glass-ceramic plate, the cooking-area burner having a gas tap and a timed-ignition and monitoring device, and furthermore the power of the cooking-area burner being adjustable. Use is made of a gas tap with a plug which can be rotated between a high setting and a low setting by means of a handle and grip shaft, with a spindle connected to the grip shaft, with a valve plate under the burnable-gas inlet opening in the plug housing, with a microswitch for the ignition device and with an electromagnet insert under the valve plate in the region of the burnable-gas supply connection of the further housing. The handle with the grip shaft and the spindle can be pushed in against the action of a restoring spring for high setting of the plug. As a result, the microswitch for the timed-ignition device can be actuated and the valve plate can be pressed onto the electromagnet insert against the action of a restoring spring, opening the burnable-gas inlet opening. The monitoring device has a thermoelectric couple which penetrates deeply into the flame of the cooking-area burner and, after 10 sec. at the latest, generates a thermoelectric current which feeds the electromagnet insert and holds the valve plate firmly. The characteristic of the thermoeletric couple and the electromagnet insert are designed so that the electromagnet insert frees the valve plate and interrupts the burnable-gas supply when the flame of the ...

Title: Target area for infrared firing practices
Inventor: WERNER HANSJOERG
IPC: F41J2/02
Filed: 1987-10-29
Abstract: A target area is specified for infrared firing practices, which target area contains an electrically non-conductive carrier board and a thermally moulded-on metal layer on the carrier board, with a target area and electrical connecting regions at the edges. The thermal moulding-on of the metal layer prevents the target area splitting at the outlet opening during firing and the target area in consequence becomes unusable for series-comparison practices.

Title: Method and apparatus for determining the specific evaporation behaviour of organic substances in thermal treatments
Inventor: OLDENETTEL HELMUT
IPC: G01N33/44
Filed: 1988-03-18
Abstract: In the heat treatment, for instance in the drying of organic substances in continuous operation, there is the problem of the limitation of the treatment temperature to a range which leads to material with desired properties. Account is taken of this by, with the aid of a sample of an organic substance to be subjected to a heat treatment, the liberation of carbon of the material being measured and recorded on heating in a gas stream as a function of a time-temperature curve. The curves determined enable the derivation of the temperature range to which the organic substance can be exposed without damage for a further processing step. <IMAGE>

Patent DE-3810482-A1 (DE)
Inventor: SODEC FRANC DR
IPC: F24F13/06
Filed: 1988-03-26
Abstract: To create a displacement-flow with low turbulence, use is made of an air exit with a cylindrical or polygonal external housing (1). In the casing of the external housing (1), there are arranged nozzles (2) which are distributed over the housing circumference. Inside the external casing (1), an internal housing (3) is arranged, the casing of which consists of a perforated metal sheet or sieve. The internal housing (3) surrounds a core space (5) which is acted upon via a connection piece (6). In order to make the jets emerging from the nozzles (2) of low turbulence and emerge with low induction into the space, and to be able to vary in a simple manner the direction of the jets, there is mounted on the end side of the external housing (1) facing away from the connection piece at least one flap (8) which is pivotable about a pin (7). As the nozzles (2) are arranged in a plane close to the flap (8), the direction of the jets emerging from the nozzles (2) is influenced depending upon the position of the flap, as according to the degree of opening of the flap (8) a part flow by volume enters into the space directly, which influences the direction in which the jets emerge from the nozzles (2). <IMAGE>

Title: Device for the selective switching of the connections between a data transmission channel and a plurality of playback devices
Inventor: SCHICK JOACHIM DIPL PHYS
IPC: H04H20/10
Filed: 1988-05-30
Abstract: In a device for the selective switching of the connection between a data transmission channel, for example an antenna connection or a cable connection, and a plurality of playback devices, the installation of a multiplicity of switchable branches from the data transmission channel to the playback devices is simplified in that, at the location of the branches from the data transmission channel, there are switches which can be switched over by means of electrical signals or reversible frequency branches or filters, and a number of switching signal leads, which corresponds to the number of the branches, is led out from a control centre on a control path connecting all the branch points with each other. Each respective switching signal lead can be loaded with a switching signal by means of an associated switching device in the control centre, which switching signal reaches the associated switchable switch or the associated reversible frequency branch or the switchable filter via the switching signal lead concerned and a tapping on the latter.

Title: Method for the point-wise generation of an image of a running material web
Inventor: STEIN WALTER VON
IPC: G01N21/59
Filed: 1988-06-06
Abstract: The invention relates to a method for the point-wise generation of an image of a running material web, in which the material web is scanned with a light spot line by line transverse to the running direction. The light coming from the light spot onto the material web is detected and converted into an electrical analog signal. The analog signal can then be scanned as a function of a time signal, in order to obtain for each image point of an image line an analog value assigned to it and corresponding to its grey-scale value, which analog value is digitised and subsequently stored in an image store for further image processing. In this case, it is provided that the digitised grey-scale values of all the image points of one image line are stored intermediately before storage in the image store, that the number of the image points scanned during scanning of the intermediately stored image line is then counted and that, before storing the digital grey-scale values of the image points in the image store, the number of the image points detected is reduced to a number of image points which can be prescribed in each case, by extracting the grey-scale values of individual scanned image points distributed over the image line. <IMAGE>

Title: Apparatus for the throughflow treatment of textile material, paper or the like
IPC: D06B23/02
Filed: 1988-06-24
Abstract: The permeable drum for the wet-treatment or dry-treatment of textile material, paper or other permeable materials of a particular width consists only of narrow sheet-metal strips or narrow webs. The sheet-metal strips extend axis-parallel, their width extension being oriented in the radial direction. The webs are oriented in the circumferential direction and are parts of the connecting elements, carrying the sieve-like covering, between the sheet-metal strips. The connecting elements also serving as spacers are made in one piece and connect two adjacent sheet-metal strips. The connection of the spacers to the sheet-metal strips is made by means of screws which have no head. The adjacent ends of two screws one following the other in the circumferential direction are screwed into a nut which can itself be surrounded by a suitable connecting element. Whilst the web of the connecting elements is in each case made narrow, the foot should be wider, in order to achieve a good sealing of the circumferential region of the drum which is not under a suction draught. <IMAGE>

Title: Method for the treatment of soot particles and exhaust emission control of an internal combustion engine and device for performing the method
Inventor: MATIJAS JOVAN
IPC: F01N3/28
Filed: 1988-07-29
Abstract: Soot particles have hitherto been removed from the exhaust gases of an internal combustion engine by means of a ceramic filter, which has to be periodically renewed, that is each time it is exhausted. The new device is intended to continuously remove soot particles from the exhaust gases without any reduction of the filter efficiency occurring. In a two-part housing, a second baffle chamber for the exhaust gases is provided in a first housing half having the inlet and a first baffle chamber in a second housing half having the outlet. The first housing half contains a static zone for the exhaust gases and - enclosed by both housing halves - a heating system, through which the exhaust gases flow three times. The device produces strong combustion of the soot particles present in the exhaust gases and is not subject to any form of exhaustion, because it does not store soot particles but largely burns them. <IMAGE>
