Abstract: A seed planting device has a planting wheel (22) rotatable about an axis (74) to roll over a land (38). Hollow tines (50) mounted at angular spacings on the wheel (22) extend outwardly. A seed cell (66) in each tine has an inlet (118) for receiving a seed and an outlet (69) towards an outer end. A seed dispensing mechanism (56) dispenses seeds individually to the seed cells via ducts (60). A release member (70) in each seed cell is movable between a retain condition for retaining a seed and a release condition for releasing the seed. Control means for controlling the members (70) includes a control rotor (92) rotatable about an axis (94) parallel to and spaced from this axis (74) a predetermined amount in a predetermined direction, and link means linking each member (70) to a predetermined position on the rotor (92) such that the member is in its retain condition while the tine moves through angular positions approaching a position in which the tine penetrates the land (38), and such that the member is in its release condition when the tine is at its penetrating position. <IMAGE>

Title: High frequency switch-mode power amplifier
Inventor: LEEDHAM ROBERT
IPC: H03F3/217
Filed: 2000-03-31
Granted: 2004-04-28
Abstract: A switch-mode power amplifier circuit using high power, low distortion waveforms is connected to an electromagnetic load to provide a high degree of control over the load. The circuit comprising a plurality of half-bridge networks having outputs combined at a summation point. The half-bridge networks are switched to provide power outputs sequenced to generate an interlaced output at the summation point which is operably connected to the load so that for a given switching frequency of the networks the operational frequency of the circuit is increased. The sequencing of the half-bridge outputs to generate an interlaced output facilitates the reduction of the switching frequency of individual switching components within the half-bridges while at least maintaining the overall operational frequency of the circuit. For <I>N</I> half-bridges operating at <I>f</I> kHz, the overall operational frequency of the circuit is <I>Nf</I>kHz. Alternatively, the switching frequency of individual switching elements of a system operating at <I>f</I><SB>o</SB>kHz may be reduced by a factor of <I>N</I>. A feedback signal generated across the load is included at the summation point and is optionally augmented to decrease distortion.

Title: Vehicle transmission apparatus
Inventor: SZYMKOWIAK ZBIGNIEW
IPC: F16H48/11
Filed: 2001-01-25
Granted: 2003-12-10
Abstract: The ATV transmission includes an epicyclic arrangement, which serves as a drive-differential. One road wheel is geared to the planet-carrier or spider, and the other to the ring gear, while the engine drives the sun. An idler-gear between the ring and its road wheel means that the ring and the spider rotate in opposite senses, whereby a large gear ratio between the sun and the road wheels can be provided. Steering of the vehicle is provided, by driving the road wheels at different speeds. This is accomplished using a steer-differential, which is identical to the drive-differential; rotating the sun of the steer-differential imposes a corresponding differential speed on the road wheels.
