Abstract: A composite oxidation catalyst for use in an exhaust system for treating an exhaust gas produced by a vehicular compression ignition internal combustion engine is disclosed. The composite oxidation catalyst comprises a honeycomb flow-through substrate monolith and two catalyst washcoat zones arranged axially in series on and along the substrate surface.

Abstract: A rail support arrangement (100, 100a, 100b, 100c, 100d, 800, 1000, 1100) to which rails (190) and/or other track elements may be coupled. A plurality of rail supports (130) are embedded in grooves (120,1121A,1121B,1122A,1122B) in a slab (110,1010). Each rail support is configured to receive a rail fastening system (160) and comprises a projection (135) that engages with the rail fastening system in order to secure a rail or other track element to the rail support.

Abstract: (100, 100a, 100b, 100c, 100d, 800, 1000, 1100) upon which a plurality of rails (190) can be supported, wobei a slab (110,1010) of the rail support arrangement is mounted to a bedding layer provided directly onto an installation area of compacted ground.

Abstract: Certain example embodiments provide a vapor compression refrigeration system, comprising: a compressor configured to suction refrigerant at a low pressure and temperature from a suction return, compress the refrigerant, and output refrigerant at a higher pressure and temperature; a condenser configured to cool refrigerant received from the compressor as the refrigerant passes though coils in the condenser; an expansion device configured to reduce the pressure of the refrigerant received from the condenser; and an evaporator configured to allow the refrigerant received from the expansion device to absorb heat surrounding the evaporator. The system may include a plurality of sensors configured to measure temperature of the system and a controller configured to control, based on the signals from one or more sensors, operation of the compressor and/or an evaporator fan motor configured to allow the refrigerant received from the expansion device to absorb heat surrounding the evaporator.

Abstract: A motor/generator unit is disclosed which is arranged to be fitted in the drive train of a vehicle, such as a hybrid vehicle. The unit comprises an electrical machine (10, 12) and a housing arrangement (14, 16). The housing arrangement comprises an inner housing (14) arranged to accommodate the electrical machine, and an outer housing (16) arranged to fit around the inner housing. This can allow the electrical machine to be provided as a self-contained unit suitable for use in different applications.
