Abstract: The invention relates to a fertilizer broadcaster with at least one centrifugal disc (5,18) arranged underneath a storage container (2) for fertilizer to be spread and equipped with sowing elements (4,19) for broadcasting the fertilizer, and with a row spreader (8,17) for the fertilization of cultivated rows, which comprises a collecting container (9) collecting the broadcast fertilizer and a guide device (16) allocating the fertilizer from the collecting container (9) to two or more hose-shaped lines (13). To ensure uniform delivery of the fertilizer particles from the collecting container (9) and especially to prevent the fertilizer grains from being broken when they strike the walls of the collecting container (9), according to the invention the centrifugal disc (5,18) is designed to achieve a throwing speed clearly lower than that for "normal spreading", but at least sufficient for broadcasting the fertilizer until it reaches all the lines (13).

Abstract: An x-ray image intensifier including an input screen 3 comprising a radiation transparent support 7 on which is applied a fluorescence layer 8 of Csl, a translucent conductive barrier layer 9, and a photocathode layer 10 e.g. of Cs,Sb. The metal layer replenishes the photocathode with electrons but tends to reflect incident light especially when made of metal, e.g. of aluminium 7nm thick which reflects about 50% of the incident fluorescence.The improvement adds first and second intermediate layers 21, 22 of metal oxide e.g. respectively TiO<sub>2</sub>, MnO, which are semiconductive. The thickness of the first layer 21 adjusts the reflection amplitude to equal that at the photocathode-vacuum interface, and that of the second layer adjusts the relative phase so that the reflections cancel. The first and second layers can be non-conductors such as Al<sub>2</sub>O<sub>3</sub>, however the second layer is then made thin enough, e.g. 25nm or less, to allow electron conduction by tunnelling to occur.Conductive barrier layers of conductive interstitial metal oxides In<sub>2</sub>O<sub>3</sub> and ITO are also described.

Abstract: The present invention provides significant improvements in the design and performance of a specific type of Rotary Membrane Filter (RMF) apparatus which has the capability of separating particles from a fluid having the same and nearly the same density as the particles by utilizing shear to achieve separation, not centrifugal forces. A particular application for the apparatus is in the processing of fluid suspensions in which the suspensions contain fragile particles which are subject to damage due to excessive shear stresses. The prior art describes processing at constant shear rate, whereas the present invention provides the design and optimization of operation of such an apparatus at constant shear stress, which is maintained at a value below that at which significant damage to the fragile particles is encountered. The use of the invention is plasmapheresis (blood separations) is described in detail, it being understood that the teachings of the invention are also directly applicable to other fluids containing fragile particles.The application of the RMF in a continuous flow processing system designed to extract blood plasma from a donor is described, including return of corpuscular components to the donor.

IPC: G01D5/20

Abstract: A reader identifies information, such as the identity of an object at a transponder, provided in binary form by the transponder. The reader initially generates a pulse which activates the transponder into transmitting a series of signals, such as by magnetic induction, to the reader. Upon each count of a particular number of signals in the reader, the reader generates an additional pulse which causes the transponder to transmit a new series of signals to the reader. The generation of the pulses by the reader may occur through the charge and discharge of energy in a storage member such as a capacitance. The series of signals produced by the transponder may have either a first frequency or a second frequency. The signals may be generated in each sequence at the first and second frequencies in an order dependent upon (a) the binary code identifying the object at the transponder and (b) the polarity of the pulse produced by the transponder in such sequence. The signals may be generated at the second frequency by connecting a capacitance across a coupling coil at the transponder. The reader then identifies the information by demodulating the signals received by it at the first and second frequencies. The reader is able to interrupt at any time the generation of the sequences of signals at the transponder when it does not receive the signals transmitted by the transponder. The reader then operates on a free running basis to generate pulses of opposite polarity at a relatively low frequency. In this way, the reader is constantly prepared to activate the transponder when the transponder becomes subsequently disposed within the effective range of the reader.

Abstract: A plasma display apparatus comprising a plurality of discharge cells is driven in two different modes. In an address mode a potential difference much larger than the discharge voltage is applied to selected cells to discharge while a potential difference smaller than the discharge voltage is applied to the non-selected cells so that they not discharge. In the following hold mode period the voltages are lowered but determined such that the selected cells can continue the discharge state while the non-selected cells require time to start discharge. 
     By this means a high brightness, small power consumption and a larger operating range are achieved.

Abstract: The device includes a horizontal body (1) with an upstream gas-washing unit (13), in which the gas to be purified is passed together with washing fluid through chambers formed between crossflow tubes (10) and producing a venturi effect, and is thus contacted with the washing fluid for a first precipitation of dust. The gas is then passed through an upward-inclined collector (23), which has a liquid seal (26) at its lowest point, on which dust agglomerates form, and through the grate bottom (19) of a foam-washing unit (17), constructed as a module, where the gas passes in countercurrent to washing fluid discharged through nozzles (21) and is further purified in a stabiliser (20) by foam-formation, before it is discharged via a separator (15) constructed in modular fashion. Owing to the foam washing unit (17) downstream of the gas-washing unit (13), economical gas purification can be obtained by matching the successive purification steps. <IMAGE>
