Abstract:
In a venting device for a fuel tank (1), a venting line (5) has a movable section (6) and a spring element (14). The free end of the venting line (5) is prestressed against an upper wall of the fuel tank (1). This ensures that a valve (7) which is arranged at the free end of the venting line (5) is always arranged in the vicinity of the upper wall of the fuel tank (1).8
Abstract:
The flushing apparatus comprises a reservoir for storing liquid, the reservoir having an outlet end movable between a raised position where liquid accumulates in the reservoir, and a down position where liquid stored in the reservoir is flushed out; a counterweight for producing an effect of urging the outlet end of reservoir toward the raised position; a reservoir ballast for cancelling the effect of the counterweight when the liquid stored therein reaches a predetermined amount; a channel for channelling a liquid into an inlet of the ballast when the outlet end of the reservoir is in the raised position; and a means for preventing an overflow of the outlet end of the reservoir. There is also provided a method for flushing liquid.
Abstract:
Without a downspout extension rain water collected on the roof of a building is spilled onto the ground beside the foundation. This causes damp and musty basements and sometimes even cracked foundations. The problem with using a downspout extension is that it must be walked over; additionally it must be removed and re-installed in order to cut a lawn thereunder. The automatic extension device disclosed utilizes a rocker arm having a cup on one end and a latch/hook on the other. An upright tubular member having an upper end portion adapted to slide over the downspout and a lower end portion which elbows outwardly away from an adjacent building wall has an extension tube pivotably connected thereto. A channel extending laterally and downwardly from inside the upright tubular member to above the cup diverts rain water from the downspout into the cup. The extension tube is stored in an upright position having one end held up by the latch/hook. At the onset of a rain storm the cup is filled, and the rocker arm rotates lifting up the latch/hook; this causes the extension to automatically fall into an operable position. The extension may be rotatably lifted for lawn maintenance into its storeage position where it is maintained by the latch/hook.
Abstract:
Back flow blocker in sloping pipes, comprising a well vat (10) provided with an inlet (14) and an outlet (15) to be connected to the pipe. A tube (16) provided within the well vat and being connected at a first end to the inlet and opening at a second end in the well vat is arranged as a floating tube and is pivotally mounted in said first end to be pivoted in vertical direction from an essentially horizontal normal position when water is accumulated in the well vat maintaining said second end above the level of the water in the well vat.
Abstract:
In loading a hopper of a floating suction dredger with sand a suspension of sand and water is pumped into the hopper. After the hopper is filled up to its maximum permissible carrying capacity in a first loading step additional suspension is pumped into the hopper in a second loading step during simultaneously draining off by lowering drain means in dependence on the weight of the load of the hopper for maintaining the suction dredger substantially loaded at its maximum permissible carrying capacity.
Abstract:
An incubator shaker apparatus in which objects are shaken by rotary or reciprocating action within a bath with the drive means being external of movable means within the bath and with the movable means being drivingly connected to the external drive means through magnetic elements to eliminate a physical driving connection between the movable means and the external drive means. The invention also provides for improved means for controlling the level of the bath.
