Abstract: 1284776 Cross-point switching matrices TELEFONAKTIEBOLAGET L M ERICSSON 7 Nov 1969 [8 Nov 1968] 54749/69 Heading H4K A matrix of diode pairs DB, DC, over which set and reset currents are applied to an array of bi-stable cross-point elements Z, such as polarized relays, are selected by operation of a column relay KR followed by operation of a row relay RR, driving current of a set polarity being applied by relay BR and of a reset polarity by relay CR, initial operation of a column relay KR establishing from resistors r1, r2, a reverse bias to the diode pairs or a column such that should one of the diodes of the column conduct excessively in reverse there will be a deviation in the potential of the row wire as coupled over the associated cross-point element Z and a detector B 1 which monitors the potential of each row of the matrix will signal the fault. Should a fault be signalled in response to operation of a column relay KR, subsequent operation of a row relay to select a cross-point is inhibited. In the detector B1, depending on whether a diode DB or a diode DC is at fault in the matrix, the deviation of row potential activates a transistor pair T3, T4 over diode D2, or a transistor pair T1, T2 over a diode D1. The distinction between the diodes is not, however, preserved as the fault outputs are effectively combined and gated out by a control pulse by means of gates A1, A2, A3. The resulting fault signals thus indicates a fault existing in the matrix.

[Also in Divisions B8 and F4] A building in which particulate material (e.g. grain) is dried or ventilated and from which it is subsequently discharged by passing air through louvred panels in the floor, comprises a floor having a first portion in which the louvres direct air in one direction towards a discharge outlet, and a second portion in which the louvres direct air towards the first portion and in a direction transverse to the one direction. In one embodiment, the building comprises a main air conduit 28 which extends through the building and can communicate with two adjacent parallel air conduits 66, which are made of a plurality of sections, and a plurality of lateral air conduits 13 which can communicate with the air conduits 66. The conduits 66 comprise louvred panels 46, the louvres of which direct air towards a discharge outlet (not shown). The conduits 13 comprise louvred panels 45 the louvres of which direct air towards the panels 46. In use air under superatmospheric pressure from conduit 28 is selectively supplied to each or any combination of sections of the conduits 66 and to each or any combination of conduits 13, there being flap valves between the conduit 28 and conduits 66 and between the conduits 66 and conduits 13. When material is to be discharged from the building, the outlet is opened and the material on the louvred panels 46 is conveyed by the air directly to the outlet and the material on the louvred panels 45 is conveyed over the louvred panels 46 and then to the outlet. The flat louvred panels 45 and 46 may be replaced by the louvred panels described in Specification 1,208,602, which latter panels comprise one or more V-sections, the side walls of which sections comprise louvres. The louvres in one side wall may direct the air in a direction substantially parallel, convergent or divergent to the direction of air from the louvres of the other side wall.
