Abstract: An industrial monitoring system comprises a monitoring device attached to an industrial device by a bond. Sensor data collected by the monitoring device during a commissioning period is received and used to train a machine learning model. Subsequent to the commissioning period, additional sensor data is collected by the monitoring device. An abnormal state of the bond between the monitoring device and industrial device is determined based on the additional sensor data and a characteristic inferred by the trained machine learning model. A notification of the abnormal state is generated.

Abstract: An industrial monitoring system comprises monitoring devices that are enabled for debugging by a component comprising a first microcontroller unit and a second microcontroller unit. The monitoring device receives a debugging command based on a subscription, on a publish-subscribe communications channel, to events indicative of requests to perform debugging operation. The second microcontroller unit causes the first microcontroller unit to perform the command. Results of performing the command are returned by publishing an event to the publish-subscribe communications channel.

Abstract: An apparatus, method and computer program for performing an at least partially automated commissioning of a lighting device at installation. The apparatus comprises: a wireless interface for communicating over a pre-existing public wireless network, pre-existing at said installation; a positioning module for determining a location of the lighting device; and a local control module. As part of said commissioning, the local control module determines the location of the lighting device using the positioning module, and transmits commissioning information to a register of a lighting management system by transmitting the commissioning information over the pre-existing public wireless network via the wireless interface. The commissioning information comprises an identifier of the apparatus along with the location of the lighting device as determined using the positioning system.

Abstract: A plastic pipe consisting of an outer corrugated plastic pipe and an inner smooth wall consisting of a wear resistant elastomer, particularly a thermoplastic rubber fixed in the inner bottoms wave valley to said outer corrugated pipe. The inner wall consists of a pipe which has been coextruded with the outer corrugated pipe so that the inner and outer pipe are heat welded to each other.The cavities between the inner pipe and the corrugations may be filled with a foam plastic.This plastic pipe is used for repairing or renewing a sewage pipe by installing such a pipe from a vertical shaft of the sewage system into the sewage pipes. The interstices between the outer side of the corrugations and the inner side of the sewage pipe may be filled with a mortar.

Abstract: A reusable electrophotographic element comprising a photoconductive layer containing sensitized zinc oxide particles and first and second binding agents that are incompatible is produced by employing as the first binding agent a macromolecular compound that has a higher affinity to zinc oxide than the second binding agent, is largely deposited on the zinc oxide, has an average molecular weight of at least 12,000 and is present in the photoconductive layer in an amount of 1.5 to 9% by weight calculated on the zinc oxide, with the second binding agent present in substantially larger amount. The photoconductive layer is formed of agglomerates of zinc oxide particles substantially enveloped in the first binding agent, which agglomerates have a diameter of between 2.5 and 6 .mu.m and are stuck together by portions of the second binding agent, thus providing a substantially porous photoconductive layer having a negative charge density of at most 1 m Coulomb per m.sup.2.

Abstract: In a process for the formation of an electrostatic image on a photoconductive element comprising a photoconductive zinc oxide-binder layer and an insulating top layer, the top layer is first positively charged and then is negatively charged until the element is saturated with negative charge, after which the top layer is imagewise exposed to light.

Abstract: A conducting plastic pipe system comprising a male plastic pipe part and a female plastic pipe part with conducting covering layers which are interconnected by means of a conducting sealing ring between the male and female part. In case of outer covering layers on the pipe part the covering layer extends onto the inner side of the muff end of the female pipe part.

Abstract: A pipe having an outer coating of foam plastics, a tape of thermoplastics being wrapped around the foam plastics in an overlapping way, the overlapping parts being heatsealed to each other. At least one reinforcing filament is present on the original contacting surfaces of the overlaps. Preferably one straight and one zig-zag applied filament are present.

Abstract: A process for perforating plastic tubes, in particular thin-walled corrugated tubes, by a punching or cutting operation wherein the plastic tubes are subjected to a direct or indirect treatment by a cooling fluid prior to the punching and cutting operation. The process is performed by an apparatus comprising a guide structure and conveying device for conveying the plastic tubes, and further comprising punching or cutting members, while spraying devices are provided for effecting the above-mentioned cooling treatment.

Abstract: A thermally insulated pipe particularly destined for mining industries, comprising an outer and an inner pipe, whereinbetween an insulating layer is arranged, the outer pipe being made of a synthetic material. The surface of the outer pipe is provided with an outside surface layer, being electrically conductive, which layer is connected with the inner pipe in an electrically conducting manner. The insulating material inbetween the two pipes is heat resistant.

Abstract: The invention relates to a sandwich tube comprising an inner and an outer fiber reinforced layer of thermosetting resin and an intermediate layer therebetween consisting of inorganic filler material coated with thermosetting resin and obtained by spraying a finely divided resin into a case of loosely laid inorganic filler material. A non woven is present between the intermediate layer and the outer fiber reinforced layer.

Abstract: A method and device for forming grooves in a thermoplastic pipe, by surrounding said pipe with a mould having one or more grooves in its interior wall and positioning one or two annular chambers into said pipe, a flexible sealing circular body being sealingly movable in said chamber, and the outer circumference of said body in its free state being substantially equal to the inner circumference of the mould part facing said ring minus about twice the wall thickness of the pipe in its final state. The circular body can be retracted into the annular chamber which is provided with a bottom part having a clover-leaf-like cross section, the circumference of said cross section being substantially equal to the inner circumference of said circular body.

Abstract: A stable panchromatically sensitized zinc oxide having a low moisture sensitivity with dark discharge properties rendering it suitable as the photoconductive material of elements for indirect as well as direct electrophotography is produced by reacting finely divided zinc oxide with gaseous ammonia and carbon dioxide, while keeping the zinc oxide particles in motion, until a critical stage is reached corresponding usually to a weight increase of 4 to 7.5%, at which point the reacting is terminated and the product is heated to constant weight at a temperature between 190.degree. and 350.degree. C. Photoconductive elements made with the panchromatically sensitive zinc oxide not only are reusable indefinitely under varying atmospheric humidity conditions without loss of their sensitivity, but also exhibit a memory effect much lower than that of known photoconductive zinc oxides.

Abstract: The invention relates to a method for providing a thermoplastic pipe with an inner groove, by subjecting a heat plasticized pipe to the action of some rotatably supported deforming rollers which are expanded and rotated by means of a mandril. A relative rotating motion between said deforming rollers and the pipe is maintained until the pipe is no longer permanently deformable and the relatieve rotating motion is maintained to strengthen the walls of said groove.
