Abstract: A module is proposed for a control system comprising several modules juxtaposed on a carrier, particularly an analog input/output module for receiving inputs and/or outputs. The circuit parts common to all the inputs and/or outputs are located on circuit board, whilst the specific circuit for each input and/or output is in each case provided on a separate circuit board. The circuit boards are received in sliding blocks, which can be inserted in the module casing from the front. For this purpose the casing contains several superimposed guides. The electrical connection is formed when the sliding blocks are inserted by means of plug connections which are located on the circuit board with the common circuit and the circuit boards with the specific circuits.

Abstract: A garden tilling tool having a soil penetrating portion in the form of a tine. The tool may be formed with a single tine or a multiple tine tool in the form of a garden fork or the like. Each tine has an opening adjacent to the end thereof, or formed in the end thereof, attached to, or integrally formed with, the tool are fluid delivery means, including a coupler for connection to a garden hose or the like, a valve for selectively controlling the flow of water through the coupler from a pressurized municipal water source, through the opening into contact with the soil upon penetration of the tine. In an embodiment, a water passage manifold communicates with a jet tube having an open end in close proximate relation to the end of the tine for passing water through the tool at the point of contact with the soil.
