Abstract: An apparatus for guiding work past a sewing machine needle along a predetermined path to form a line of stitching corresponding to the path with deviations of the work from a normal feed path to the needle being sensed and causing a pivotal movement of the work about the needle to overcome the deviation. The ability of the apparatus to correct the deviation is related to the speed of sewing and to maintain this sewing speed within the deviation correcting ability there are fast and slow sewing speeds and sensing means that senses the occurrence of a large deviation and decreases the sewing speed to the slow speed to enable the apparatus to correct the deviation. For sewing a line of stitching a preselected distance from the edge of a workpiece, the vertical axis on which the work is pivoted is slightly tilted so that the workpiece is positioned to have the portion of its edge at the needle normally extend transversely beyond the needle a distance greater than the preselected distance from the needle.

Abstract: Use is made of the discovery that "near" ultra-violet radiation is effective in attracting large enough quantities of insects entirely from within the water to feed substantial numbers of animals without attracting flying insects from the air. Radiation from lamps producing predominantly near ultra-violet radiation, that is, radiation whose wavelength is between 3,000 and 4,000 angstroms, is directed into water in which insects live. The insects which are attracted by the radiation are fed to the animals. Preferably, the insects are attracted towards an insect enclosure with a downwardly-facing entrance in the water. A near ultra-violet lamp in the enclosure attracts the insects into the enclosure, from which they cannot escape into the air above the water. Fish or frogs in a cage are positioned below the enclosure to eat insects in or rising towards the enclosure. In one embodiment, only the lamp is used; the insects are numerous enough to allow some to escape and still feed substantial numbers of animals.

Pulses from the second pick-up are counted during a predetermined interval (T) initiated by a pulse from the first pick-up to provide a count which is stored as a reference value representing the required spark advance angle, this stored reference value being subsequently compared with the number of pulses from the second pick-up counted with the commencement of the next pulse from the first pick-up to provide a spark-triggering pulse upon parity of the number of these subsequently counted pulses with the reference value.

Abstract: A plunger slidable in a barrel of a plunger pump is actuated by an engine driven camshaft to feed high pressure fuel through a delivery valve to an injection nozzle. A needle type valve element extends through a nozzle chamber in the nozzle connected to the pump to control fuel flow from the nozzle chamber through an injection orifice into the engine. The needle end of the valve element is exposed to pressurized fuel in the nozzle chamber, and a spring applies a force to the other end of the valve element to urge the valve element to block the injection orifice. As the pump plunger moves through its injection stroke, the pressure in the nozzle chamber increases and overcomes the force of the spring to move the valve element to unblock the orifice to initiate fuel injection.

A closed loop electronic servo system is provided to position the movable part of the barrel in accordance with the required fuel injection volume.
