Abstract: ABSTRACT OF THE DISCLOSURE     A four-cycle internal combustion engine comprises a housing defining an internal compartment having one or more paripheral lobes, an inner body mounted in the housing for non-rotational orbital movement and having a pluality of peripheral lobes corresponding in number to the number of compartment lobes, and with a peripheral recess in the inner body between each inner body lobe. A movable wall member is mounted for movement in each inner body peripheral recess and defines with the housing and inner body, a variable-volume fluid intake and compression chamber. The inner body is mounted in the housing compartment so that each of its peripheral lobes moves in a circular orbit into a respective one of the compartment lobes during movement of the inner body, and the inner body lobe, housing, and movable wall member define a variable-volume power chamber and exhaust chamber in each of the compartment lobes during movement of the inner body. The inner is operatively connected to a power output shaft to impart rotary motion thereto during orbital movement of the inner body, and the peripheral wall of each inner body inner body lobe is configured so as to impart forces of combustion in the power chamber at a substantially right angle to the crank angle of the power output shaft during the major portion of the power cycle of the engine. The housing is provided with intake and exhaust port means communicating with the internal compartment, and passageway means are located in the inner body and housing to intercommunicate the intake and compression chamber with the intake port means the power chamber during a portion of orbital movement of the inner body, and to communicate the exhaust chamber with the exhaust port means during a portion of the movement of the inner body.

Abstract: ABSTRACT            AXIAL GAP SQUIRREL CAGE INDUCTION ELECTRIC MOTOR        The stator (21) of the motor is of annular form, with generally radial slots (22) which receive the energising windings.  The squirrel cage of the rotor has a magnetic component (16) and a conductive component comprising inner ring (10) and outer ring (12) joined by bars (14).   The bars (14) are curved so as to follow a path with a higher radial component at the inner end than at the outer end.  This reduces perceived noise by avoiding sharp registering of the rotor bars with the stator slots, and also by providing a more uniform ratio of magnetic to conductive material in the rotor at different radii around the rotor axis.

Abstract: Abstract Method and device for planting pot plants by means of a planting machine travelling on the ground so that a planting furrow is formed and the plants are fed into the planting means of the planting machine. The planting means grasps the plant, lowers the plant down towards the planting furrow, and lets the plant loose above the planting furrow. Thereupon, the plants having assumed a substantially vertical position in the planting furrow, the planting furrow is closed. As the plant is detached from the planting means, the component of speed of the speed of the planting means and of the plant, opposite to the direction of travel of the planting machine, in relation to the planting machine is substantially higher than the speed of the planting machine in relation to the ground.

Abstract: ABSTRACT OF THE DISCLOSURE      A tank suitable for holding a lubricant is provided with a dipstick. A sleeve which is mounted on the tank and adapted to support the dipstick is interconnected with the output duct of the tank by means of a further duct.  The arrangement is such that if the dipstick is incorrectly located in the sleeve, air is permitted to flow through the further duct into the output duct so that the pressure of the lubricant in the output duct is reduced.  This pressure reduction consequently provides an indication of incorrect dipstick location.

Abstract: 2 ? 33a ABSTRACT           An apparatus for engaging and transporting discrete sheets downstream of a severing station at which a cross-cutter severs a running paper web has a catcher assembly with an upper and a lower conveyor unit.  The conveyor units define an elongated path for the transport of sheets therebetween.  The catcher assembly is adjustable, in its entirety, with reference to the severing station, and each conveyor unit is adjustable relative to the other conveyor unit.  The rearmost portion of the upper conveyor unit is adjustable toward and away from the adjacent portion of the lower conveyor unit.  Such adjustability of the catcher assembly, of the conveyor units and of the rear portion of the upper conveyor unit enables an attendant to counteract the tendency of the leader of the web to miss the entrance into the path for successive sheets between the upper and lower conveyor units regardless of whether such tendency is attributable to the propensity of the web to curl, to excessive or pronounced flexibility of the material of the web, to the weight of the material of the web, to the generation of eddy currents at the severing station owing to rotary movement of the severing instrumentalities, and/or any combination of such factors.

Schwab ABSTRACT OF THE DISCLOSURE       Some seeds or varieties thereof, particularly grains like sorghum and barley, or legumes like beans and peas, contain tannins in undesirably toxic amounts even for use as animal feed.  It has been found that such seeds can be detoxified by steps comprising (a) imbibition of water or acidic solutions into the seeds, and (b) storage thereof under non-evaporating conditions which preclude microorganism growth, until the tannin content is deactivated and reduced to nutritionally-desirable levels by chemical modification.          As an alternative in step (a), the seeds can be early -harvested at elevated moisture content.
