The invention relates to an arrangement and a method for cleaning fine solid particles from a continuously flowing liquid suspension. According to the invention, alternate emptying of cleaned liquid in at least two decanting chambers ( 34, 36 ) of the cleaning arrangement ( 10 ) is brought about by alternately opening and closing valve units ( 48, 50 ) coordinated with outlets ( 44, 46 ) of the decanting chambers ( 34, 36 ). Alternatively, valves in feeds to at least two separate inlet tanks of the cleaning arrangement can be opened and closed alternately in order to bring about a continuous outflow of cleaned liquid.

A communication unit comprised a first and second splitting/combining device, each having terminals for receiving and transmitting a CATV signal and a data signal, respectively, means for combining the CATV signal and the data signal and a third terminal for receiving and transmitting the combined signal. The first terminals of the splitting/combining devices are interconnected through a device for extracting said CATV signals and each of the second terminals is connected to a switch controlled in such a way that the second terminals are either connected to each other directly or connected to a connection device for connection to a computer. The data signal can bypass flats desiring no data connection. Also, the communication unit may be implemented in two parts: one wall mounted part and one adapter connectable to the wall mounted part and comprising the connection unit, which is needed only where a data connection is wanted.

A method for serving animals, such as milking dairy animals, allowed to go loose in an enclosed area, with animal stalls with a robot, said stalls having entrance (6) and exit (7) gates being controlled by a control means for being opened and/or closed. The invention also refers to an apparatus for serving animals, using the invented method. The invention improves the known method and apparatus to achieve an increased efficiency by arranging a service area (3) such as to comprise at least three stationary animal stalls (4), placing the animal stalls (4) around a robot (5) to form a central robot inner area, and arranging a displaceable service and/or milking robot (5) in said inner area, said robot (5) being associated with said control means and being capable of moving to and serving each one of the animal stalls (4). The efficiency is further increased by arranging a strolling area between the outer border (2) of the enclosed area (10) and the central robot area with animal stalls (4) and dividing said strolling area (10) into subareas in various ways by the use of separation means (9, 11) which also may comprise controlled one-way passing gates (14) for the animals.

A machine for manufacturing packages for compact discs or similar out of cardboard work pieces. The packages consist of a casing part and a slide part inserted therein, with a compact disc and a booklet. These two components are manufactured in separate tracks (A, B), which consist of jigs, whereby each of these rotates stepwise in a rotating table. The casing parts are manufactured by laying down the forward half of a work piece on a placing plate (1), laying down a cover (2) over this, the cover having the same outer shape as the inside of the finished casing, folding its edge upwards with first folding devices (7), folding over its edge with second folding devices (9, 10), applying melt glue on the top flap and laying down the rear half over disc, and squeezing by means of the second folding devices until the glue has stuck. After turning the folding devices away, the cover is turned upwards and the completed cover can be pulled off for being passed on to a ready position in front of a jig position in the second rotating table, where a jig, which during a work revolution has produced a finished slide part with disc and booklet inserted, by means of pushing means and funnel means passes this into the casing, standing in the ready position.

A teatcup supplying and retrieving device (4) comprises a teatcup supplying member (5) and at least one teatcup (10) connected to a tubing (11), said teatcup being provided with a teat entry end (19) having a surface defining an inlet opening (20) for a teat. According to the invention, said teatcup (10) is displaceable from a first position to a second position, in which said teat entry end (19) is directed differently from that of the first position, wherein said teatcup (10) is freely displaceable in relation to said teatcup supplying member (5) during displacement between said first and second positions, said displacement being at least initiated by a displacement means (8) controlled by a control means. Furthermore, according to the invention there is provided an automatic milking apparatus comprising a milking robot provided with a robot arm (3) to be used in conjunction with such a teatcup supplying and retrieving device (4).
摘要:
A switching circuit for connecting transceivers (TX, TX') for different frequencies alternatively to a common antenna (1). Each frequency disposes of a set comprising a plurality of PIN diodes (D1, D2; D1', D2') connected in series, and the PIN diodes in a set may be activated by a DC current (from VC1), which DC current is led through a bias resistor (3), creating a bias voltage. This bias voltage is used for reverse biasing the PIN diodes in another set, thus eliminating quiescent PIN diodes therein from creating spurious signals. The circuit is particularly suited for cellular mobile telephones using two frequency bands.

An animal related apparatus comprises a robot (6) for performing an animal related operation, said robot being associated with a control means, and at least one animal related device (12a) associated with said control means, said robot being provided with a robot arm (8) adapted to move said animal related device towards an animal. According to the invention, a registering means (20a) is provided for registering a cumulative running value, said control means being adapted to generate a signal when a predetermined threshold value has been reached.

This invention relates to a system for measuring patterns in finger surfaces, the system comprising an array of sensor electrodes over which the surface is to be moved, and at least one stimulation electrode for providing a varying current or voltage between the stimulation electrode and the number of sensors through the surface. The stimulation electrode is positioned separately from the array of sensor electrodes and the system comprises a generator coupled to the stimulation electrode for applying a current or voltage with a varying amplitude or phase to the surface. The system comprises a measuring unit coupled to the sensor electrodes for, during the application of the current or voltage, measuring the impedance at the sensor electrodes in a time sequence and calculating values of predetermined characteristics of the surface and combining the calculated values for the sensor electrodes over the time sequence for generating a representation of the surface pattern.
