Patent EP-0086182-A2 (EP)
Inventor: LENELL LARS ANDERS
IPC: H04Q3/00
Filed: 1983-01-26
Abstract: An electronic line repeater for connecting a two-wire line to a subscriber exchange is impedance-matched to the two-wire side with the aid of a feedback circuit from the two-wire side of the repeater to the incoming four-wire side. The feedback includes a differential amplifier (F1) which senses the speech voltage drop on the two-wire side, and a resistor (R) connected to the line amplifier (F2) of the repeater. Impedance matching can be achieved by definite values of the gain provided by the differential amplifier and the line amplifier.

Abstract: It is known that the human influenza virus strain A/Puerto Rico/8/34 grows particularly well in eggs and that reassorted viruses having it as a parent may also grow well in eggs. It has now been found that certain reassortants of A/PR/8/34 and equine influenza viruses, namely those which comprise the RNA7 segment from A/PR/8/34, will grow in cell culture, even though the parent equine influenza virus will not. 
     Thus the specification describes and claims: reassorted viruses comprising genes for surface antigens of equine influenza viruses and the RNA7 segment from A/PR/8/34; methods of obtaining such viruses by reassortment; methods of propagating such reassorted viruses in cell culture, especially Vero cells; vaccines against equine influenza comprising such reassorted viruses; and methods of vaccinating equines against influenza.

Abstract: The composting plant for refuse and sludge, according to the present invention, has an inclined base and mixer screws which do not have air induction channels. They are placed on axes which are perpendicular to said base and which rotate around and move along said axes, respectively during mixing and homogenization of the material to be treated and during return and travel starting. These screws are carried on a mobile bridge whose carrying beam is parallel to the generally inclined bottom of the composting reactor and has the relative mobile supports for rolling resting on a concrete bed in direct contact with the ground. 
     The air required for the treatment of the material is sucked from the bottom of the reactor through channels cut into said bottom and covered by means of protection to avoid blockage caused by deposits of composting material which may infiltrate. 
     The same are removed by periodic washing with water, pumped inside the channels by means of special devices.

Abstract: A method for amplifying an electrostatic, charge pattern is disclosed. The method comprises (a) imagewise forming a first toner deposit by developing a first electrostatic charge pattern having a first charge-differential-per-unit area whose maximum value is no greater than a preselected level, (b) forming, in an image-amplification element comprising a charge-holding surface layer overlying a field-supporting electrode, a current-carrying path between the toner deposit and the field-supporting electrode, (c) under conditions in which nontoned regions are not photoexcited, overall charging the image-amplification element with sufficient charge to form an enhanced electrostatic charge pattern having a second charge-differential-per-unit area whose maximum value is greater than the preselected value in step (a), and (d) developing the enhanced charge pattern into a second toner deposit. By this process, high-maximum-density, continuous-tone images can be produced wherein the maximum density of such images is obtained by amplification of initial charge differentials whose maximum valve is, for example, no greater than 30 nanocoulombs/cm<sup>2</sup> or lower. In addition, images can be produced with low contrast, i.e., obtained over a wide exposure range.

All the connecting pieces (21) which are used for making contact with the contact pins of a relay or such like are of the same design. The connecting pieces (21), which must carry, for example, the high currents flowing through the relay contacts, are directly connected to the connecting terminals (29) so that these currents do not have to be passed through the conductor paths of the printed circuit. Nevertheless, these connecting pieces (21) have a contact pin (19), so that it is possible for them to be connected to a display device or other devices, for example, via the conductor paths of the printed circuit. The socket (10) has an oblong form and the connecting elements (33) of the connecting terminals (29) are arranged on a narrow side such that a plurality of sockets (10) can be arranged in a row on the printed circuit. <IMAGE>

Abstract: A method and system for high speed image reproduction by electro-coagulation of an electrolytically coagulable colloid. A plurality of negative and positive electrolytically inert electrodes (12, 14) which are electrically insulated from one another are arranged to define a matrix of dot-forming elements (16), the negative and positive electrodes of each matrix element having respective planar active surfaces with the negative electrode active surface extending in the same plane as the positive electrode active surface and in close proximity thereto. A layer of substantially liquid colloidal dispersion is applied over the electrode active surfaces of the matrix elements (16), the colloidal dispersion containing an electrolytically coagulable colloid, a liquid dispersing medium and a soluble electrolyte, and having a substantially uniform temperature throughout the layer. The negative and positive electrodes (12, 14) of selected ones of the matrix elements (16) are electrically energized to cause selective coagulation and adherence of the colloid onto the positive electrode active surfaces of the selected matrix elements and to thereby form a series of corresponding dots representative of a desired image, and any remaining non-coagulated colloid is thereafter removed.

Abstract: A magnetic-pole core for an electrorotary machine, such as a DC or AC motor, has pole sections (17) which extend over the side of a coil (4) from base sections (10,11). Each pole section (17) has two sub-sections or pole pieces (20 and 21) and one of these pole pieces (20) has an extended section (22) which extends circumferentially of the coil. This structure prevents the formation of a start-up dead-point by enabling the centre of the magnetic poles of the armature (which include the pole core) to deviate circumferentially from the centre of the poles, or the mid-point between poles, of a field magnet around the armature. The core also permits uniform rotation. There may also be a third pole piece (3) between the first and second pole pieces (21,22) and all the pole pieces may be integral with the base section (10,11) from which they extend.
