Abstract: A dataflow processor comprising a combiner for combining instructions and data, processing elements for carrying out the instructions, has error checking at the inputs to the processing elements and the combiner, and has self-checking circuitry for these parts. The amount of circuitry which needs to be trusted, (i.e. of proven design, and verified operation) can be advantageously limited. This enables the processor to be constructed more simply and to operate faster. The processing elements may have a series of state machines, each checking the output of the previous. Self checking circuitry may be constructed using combinations of basic configurable verified circuit. This circuit has a reversible Boolean function, and other circuitry to check its output. The other circuitry has a second reversible Boolean function for regenerating the original inputs, and a comparator for verifying if the regenerated values match the original values.

Abstract: Application services gateways that execute electronic application programs/services allows the application programs/services to be managed and administered out of a network rather than locally. The application services gateways are elements in a services delivery system that execute application programs/services that control or otherwise interact with systems and devices of a home or business such as a heating and cooling system or a security system. The application services gateways have a LAN connection to a communication gateway that in turn communicates over a WAN to a remote services gateway. The remote services gateway channels data from a remote service platform to provide application programs/services and management services over the WAN to the communications gateway where it is then channeled to the application services gateways.

Abstract: An HPNA bridge comprises a bi-directional filter for blocking non-HPNA signals and splitter for distributing the filtered signal to at least one additional telephone wire pair. The filter may be a high pass filter allowing signals with a frequency above a threshold value, including HPNA signals, to pass. Alternatively, the filter may be a band pass filter allowing only signals within the HPNA frequency range to pass.

Abstract: An infinitely variable drive transmission including an input member, a summing gear set, and a variable speed transmission having an input element drivable by the input member and an output element, the output element of the variable speed transmission being connectable to one element of the summing gear set, to provide a first path between the input member and the summing gear set. The input member being connectable to another element of the summing gear set to provide a second path between the input member and the summing gear set. The summing gear set includes a driven member drivable by at least one further element of the summing gear set and drive transmitting means connectable between the output element of the variable speed transmission and the other element of the summing gear set.

Abstract: Precombustion ionization devices are disclosed for treating the vaporizable liquid fuel in internal combustion engines, including at least one foraminous member prepared from a catalytic metal having an oxide coating on the surface thereof. The foraminous member, or screen, is spaced from the carburetor and the engine intake of the internal combustion engine by means of a supporting gasket. The disclosed precombustion ionization devices may also be attached to a source of relatively high voltage, resulting in increased ionization of the vaporizable liquid fuel thereby, and preventing electropolishing of the metal oxide coating.

Abstract: A gear box serving as a transmission coupling between nominally co-axial driving and driven shafts with a gear train within a casing of the gear box coupled to these shafts by flexible couplings that are disposed within the casing about the centers of bearings on which the casing is mounted.

Abstract: A control mechanism for operating the drafting gate of a drafting race comprising a superstructure adapted to be mounted above the race, an operating handle suspended from the superstructure substantially parallel with the race for rocking movement about a substantially horizontal axis substantially parallel with the race and at a position so that it can be gripped by an operator standing at one side of the race, one end of the operating handle being coupled to the drafting gate to effect rotation thereof.

Abstract: A flexible, cantilevered, gear wheel support, comprising a flexible pin mounted at one end in a rotating carrier and carrying at the other end a gear wheel the axis of which, when the pin flexes, remains parallel to the position of this axis in the pin unflexed condition; the pin between its mounting on the carrier and its part that carries the gear wheel presenting a greater resistance to bending in planes radial of the rotational path of the carrier than it presents to bending in planes tangential to this path.

Abstract: A flexible, cantilevered, gear wheel support, comprising a flexible spindle united at one end with a carrier and at the other end with a gear wheel support sleeve by means of welds effected by electron beam welding.

Abstract: A gear wheel support of composite construction and comprising a gear wheel support sleeve with an internal abutment pillar secured in abutting relationship with an abutment pillar protruding from a face of a carrier, these pillars together comprising a flexible spindle co-axial with the sleeve with an annular clearance between this spindle and the sleeve.
