Abstract: An ignition system is provided for creating a continuous stream of high voltage pulses to each spark plug (8) over a predetermined period of time as controlled by the distributor (7). Below the transformer core (1) is positioned a switch (6) incorporating a plate (9) which is magnetically attracted to the transformer when a current flows through the windings. When the contacts of the contact breaker (5) open the supply from the battery (4) to the transformer core (1) is cut off so that the switch (6) closes under the bias of a spring due to the collapse of the magnetic field created in the core. Closure of the switch (6) restores the circuit from the battery (4) to the primary and secondary windings (2) (3) of the transformer and thus during the whole period that the contact breaker (5) is open the switch (6) will intermittently open and close, resulting in the application of a rapid series of high tension pulses to the respective spark plug (8 ).

Abstract: An open framework defining a pair of rows of stalls for livestock, a feeding hopper movable over the rows of stalls and having a pair of food material discharge openings each disposed to deliver food to the stalls of a different row. A pair of feeding conveyors in the hopper each feed material to a different one of the discharge openings and are independently driven and independently controlled by control elements causing the material to be discharged to predetermined ones only of the stalls. The framework includes longitudinal frame sections which provide gates to each of the stalls individually.

Abstract: A crop-gathering table for a combine harvester has a tubular main cross beam on which are supported at spaced intervals a plurality of angle iron ribs extending downwardly and then forwardly to support the back wall and then the bottom wall of the table and to support the cutter bar at the front end of the ribs. A stiffener plate is secured to the bottom of the ribs so that with the bottom wall of the table a plurality of hollow cells are formed to provide a rigid but lightweight table structure.
