Abstract: There is provided a network interface module, and a method of implementing deterministic response frame transmission therein. The network interface module comprises a processor core arranged to execute a set of threads, the set of threads comprising at least one transmit thread arranged to cause a response frame to be transmitted upon expiry of a minimum response period from a response triggering event occurring. The network interface module further comprises a timing component arranged to output a masking timeout signal indicating expiration of successive masking timeout intervals, and a masking component arranged to mask the transmit thread from being scheduled for execution by the processing core. The masking component being further arranged to receive the masking timeout signal output by the timing component and to unmask the transmit thread upon expiry of a masking timeout interval.

Abstract: An interface system has a first media access controller having a first MAC buffer for storing at least one first-type frame in a first frame format according to a first communication protocol. A time synchronization module is arranged to, upon detecting the start of the first-type frame, determine a first timestamp from a master clock signal and latch the first timestamp into a first timestamp register. A processor is arranged to: retrieve the first timestamp from the first timestamp register, and transfer a first-type frame between the first MAC buffer and a first local memory in a block-wise manner as a plurality of blocks. The processor is arranged to process the plurality of blocks of the first-type frame using the first timestamp as retrieved from the first timestamp register.

Abstract: A radial-flow pump (1), and especially a coolant pump for an internal combustion engine, comprising an impeller (2) provided with vanes (5) and a directing device (4) including at least one temperature- and/or speed-sensitive element for temperature-dependent control of the coolant flow, where at least one impeller vane (5) and/or the directing device (4) is configured as a speed-sensitive element. In order to increase efficiency, the proposal is put forward that the impeller vanes (5) should be elastically deformable by Coriolis forces of the coolant flow, the discharge angles (&agr;), which are preferably defined between impeller vanes (5) and impeller tangential planes (&egr;), decreasing with an increase in speed.

Abstract: The invention relates to an oil pump for an internal combustion engine with at least one pair of toothed wheels which are in mutual engagement, at least one intake port and at least one outlet port. An improved supply of oil at reduced driving power can be achieved with at least two pairs of toothed wheels; a first common shaft, which a first toothed wheel of each pair of toothed wheels is arranged, and means are provided to charge the individual pairs of toothed wheels with oil depending on the required quantity of conveyed oil.

Abstract: The invention relates to reaction resins formed from anionically polymerizable di- or tri-functional epoxy compounds which are suitable for impregnating and/or casting large-volume parts. Such reaction resins therefore contain tertiary amine polymerization catalysts of the general formula ##STR1## in a concentration of 0.5 to 10 mass parts, relative to 100 mass parts epoxy compound.

Abstract: The specification describes an apparatus for stacking and unstacking sheet material, more particularly glass sheets, comprising one or more suction plates, capable of moving towards a sheet material stack and adapted to be moved by a pressure cylinder actuator, and with a sensing member, which on making contact with the stack, the surface position of which changes as the stacking or unstacking progresses generates a pulse adapted to control movement of the piston rod of the pressure cylinder actuator. As a sensing member a switch (vacuum monitor, pressure monitor) responsive to changes in pressure is provided in the suction duct system of the suction plates and/or in the pressure duct system of the pressure cylinder actuator.
