Patent NL-8001412-A (NL)
IPC: A01B45/02
Filed: 1980-03-10
Abstract: The apparatus has pins (15) which are pivotably connected to the end of a first rod (5) which is pivotable (8) with its other end in the frame of the apparatus, a second rod (11) extending substantially parallel to the first rod (5) being pivotably connected with one end (12) to a point of the pin (15) below the pivot point (4). The other end (10) of the second rod (11) is likewise pivotably provided in the frame of the apparatus, the second rod having a yielding portion (16). The pins (15) penetrate into the soil substantially along a straight line, but pivot rearwardly around the pivots (4) as permitted by the resilient portion (16) in the second rod (11). Thereby the hole made is widened at its lower end for better water storing capacity while at the same time the soil is crumbled and the hole wall made porous for better water permeability. During the pivotal movement of the pins they remain substantially stationary at the location of the soil surface or turf, so that no damage of the turf is produced.

Patent NL-8103859-A (NL)
Title: Control system for gas-fired boiler - controls gas flow by temp. comparator circuit and heating element, mounted on capillary valve
IPC: F23N5/02
Filed: 1981-08-18
Abstract: This circuit controls the flow of gas to a gas-fired heating system by means of a conventional capillary valve. The temp. in the room to be heated is detected by a transducer and compared with the signal from the temp. control switch by a differential amplifier. The output of the amplifier is fed via a limiting circuit to a second differential amplifier. The other input to the second amplifier is from a temp. detector mounted on the capillary tube. The output of the second amplifier is fed to a circuit which controls the current flow through a heating element around the capillary. If the temp. in the room drops below the selected level, the heating element on the capillary produces less heat, allowing the capillary temp. to drop, thus opening the gas valve further.

Title: Mixing device for silage
Inventor: LIET CORNELIS HENDRICUS
IPC: A01F25/20
Filed: 1994-01-28
Abstract: The invention relates to a mixing device for silage, provided with a mixing chamber, a mixing element which can move inside the mixing chamber and is formed by two revolving, endless elements which are connected by drivers, and a loading platform which extends substantially vertically, for feeding the silage into the mixing chamber.
