Abstract: Abstract of the Disclosure An internal combustion engine comprises a carbure-tor, which precedes an intake passage, at least one cylinder, a piston movable in said cylinder, intake and exhaust valves and igniting means.  A flow-guiding element extends in said intake passage and defines therein a flow passage which tapers along said intake passage toward the intake valve so that the velocity of flow of the fuel-air mixture flowing in said flow passage will be progressively increased. The flow-guiding element may consist of a funnel-shaped tubular member or of a flow-guiding strip.  The smaller end of the tubular member is disposed close to the intake valve and near that side of the intake passage on which said igniting means are disposed relative to the intake valve.  Near its end opposite to the intake valve, the tubular member has a projection, which constricts another flow passage, which surrounds the tubular member in said intake passage.  The flow-guiding strip gradually approaches the boundary wall defining the intake passage on that side thereof on which said igniting means are disposed relative to said intake valve.

Abstract: ABSTRACT OF THE DISCLOSURE A method and a device for attaching a rail on a timber support.  The device includes a helically threaded fastener adapted to be screwed into a helically threaded borehole in the support after a rectangular metal insert is positioned in a rectangular opening at the periphery of the borehole.  The borehole is sufficiently large that the fastener only contacts the timber support via contact with the insert.  The rectangular opening is longer than the insert so that there is radial play between the insert and one end of the insert.  The other end of the insert is ad-apted to contact a sloped side of the thread of the fastener. As the fastener is screwed into the borehole, the sloped side of the fastener presses the insert parallel to and perpendi-cular to the screwing axis of the fastener.  As a result, the insert elastically expands parallel to and perpendicular to the screwing axis.  Because the expansion perpendicular to the screwing axis is less than the radial play, no radial for-ces act on the timber support.  Rather the timber support is only compressed parallel to the screwing axis thereby pre-venting the timber support from splintering.

Abstract: Abstract of the Disclosure A bus structure for use in a computer network requiring high availabilty and reliability of communications.  Multiple bus paths are provided.  When a transmission is to be made, under most circumstances the path is selected at random, with all paths being equally probable. Thus, failure of a path is detected quickly. Each host device in the network connects to the bus paths through an interface, or port.  The task of path selection is carried out by the ports, independently of the host devices.  The ports also detect path failures and automatically switch over to an alternate good path upon detection of such a failure, all without host involvement.  Virtual circuit communications between hosts are transparent to path selection and switching, so the only indication to a host device of a path failure is a decrease in throughput.  Most of the signal processing apparatus of each port is shared by the paths, only one path being supported at any given time.  Thus, the addition of a second bus path involves only minimal cost.

Abstract: ABSTRACT OF THE DISCLOSURE A very rapidly converging adaptive filter which uses a variable scale factor for each weight of the filter.  The size of the variable scale factor is chosen for each iteration and is based upon the sign changes of the in-cremental weight change.  The variable scale factor permits large step sizes when no sign changes occur and smaller step sizes when sign changes occur.  The new filter provides considerable improvement in convergence rate and residual errors even in the presence of heavy noise while requiring only a modest increase in hardware.
