Title: Seed potato planter with vibratory hopper - has bucket feed conveyor and photoelectric controlled feed belts
IPC: A01C9/02
Filed: 1974-03-04
Abstract: A frame (1) has a drive wheel (2) and is semi-mounted on a tractor. It supports a potato hopper (12) whose base contains two inclined endless belts (10) forming a V which brings the potatoes to a spout (5). The potatoes are prevented from bridging by vibrating the inner walls (21) of the hopper. In the centre of the hopper near the outlet is a wheel bearing flexible fingers which feed the potatoes gently through the outlet to bucket conveyor (26). This operation trips a phot-electric cell which stops the feed belts. The potato falls from the conveyor bucket, at the end of the latter's downward travel, into a drill prepared by share (19) and covered by a rake (18). As soon as the potato leaves the bucket, the photo-electric cell is activated, setting the feed belts in operation once more.

Title: Aneroid cell pressure change indicator - centrally pivoted contact moved frictionally
IPC: G01L19/08
Filed: 1974-03-25
Abstract: The direction in which a variable is moving, up or down, particularly barometric pressure as indicated by the movement of an arm attached to an aneroid cell, is indicated electrically by signals derived from a two position contact assembly. This assembly has a central contact freely pivoted and with no restoring springs. The arm of the barometer carries a needle like projection (19) which passes through a hole in the central contact. The needle being split exerts frictional forces on the sides of the hole, so that any movement of the arm causes the contact to follow, subsequent movement having no further action on the contact until a reversal of motion occurs. Various battery and bulb circuits are possible.
