Title: Decanting Aid and Method for Decanting Enclosures
IPC: B67D99/00
Filed: 1980-12-12
Abstract: A method of decanting liquids having sediments, from an enclosure 15, comprises inserting a decanting aid into the enclosure. The aid comprises a length of tubing 11 with a clip 12 which engages the side of the opening and so holds the tubing to that side. The bottom end of the tubing can be provided with a oneway valve arranged to stop entry of the liquid into the tubing. Liquid is decanted without disturbing any sediment since air enters the enclosure smoothly through tube 11 rather than by an irregular sequence of inrushes of large air bubbles. <IMAGE>

Title: Improvements in suburface soil opening implements
IPC: A01C23/02
Filed: 1981-01-12
Abstract: A machine for burying slurry, sewage, or other soil-improving fluids has a hollow straight forward-leaning tine which carries at its bottom end an arched, forward-sloping delta-shaped shoe for lifting the soil into the form of a tunnel. The hollow interior of the tine opens through the roof of this shoe, and slurry is delivered through the tine into the cavity under the shoe. A free-running vibrator on the tine vibrates it and the shoe vertically. The tine is resiliently loaded by a spring to its working position, and the reaction of the spring is applied directly to a reaction lever separately pivoted on a subframe carrying the tine. The spring reaction biases the lever downwards, and the lever is supported at its rearward end behind the tine by a roller which closes the slit formed by the tapered leading edge of the tine.

Patent GB-2109716-A (GB)
Title: Vacuum workpiece holder
Inventor: WOOD KENNETH O
IPC: B25B11/00
Filed: 1982-09-16
Abstract: A vacuum chuck for holding a workpiece 31 has a chuck or work holding area over which a large number of suction cells 22 are distributed. When a workpiece is placed on the work area each suction cell covered by the workpiece applies vacuum to the workpiece bottom over a relatively large area to produce a force holding the workpiece to the chuck. Each suction cell is connected to a vacuum space 30 by a flow path 34 exclusively serving that cell and including a restriction permitting air to flow from the suction cell to the vacuum space at only a very low rate when the cell is uncovered. The total air flow to the vacuum space when all of the suction cells are uncovered is sufficiently small that a relatively small capacity suction pump or similar vacuum source can maintain a significant vacuum in the vacuum space sufficient to operate the holder. Therefore, workpieces of different sizes may be used with the holder without having to modify or adjust the holder in any way and without having to seal the exposed portions of the work holding area. A manually operable vacuum venting valve, associated with the vacuum space, is provided for releasing the workpiece from the holding force to facilitate transferral of workpieces to and from the holder. The restrictive flow paths may be provided in an alternative embodiment in an air-impermeable flexible material 53 spread over the work-holding area. <IMAGE>

Patent GB-2134175-A (GB)
Title: Pneumatic door actuator
Inventor: VINER GEORGE CHARLES
IPC: E05F15/02
Filed: 1983-12-23
Abstract: The actuator has an actuator rod driven by a piston 1 working within a cylinder 2, opposite ends of which are selectively pressurised and vented to provide motive effort for the piston. If a closing door is temporarily obstructed the pressure in the vented end 3 of the cylinder may drop sufficiently to cause the door to be slammed shut when the obstruction is removed. The appropriate cylinder end is thus vented through a valve 20 which is unseated by a piston 13 when the difference between the pressure remaining in the cylinder and the exhaust port vent 12 exceeds a predetermined level. When this pressure difference falls a spring 23 operates the piston 13 closing the valve trapping the remaining pressure so that it acts as a cushion when piston movement is resumed. For damped end movement of the piston 1, a ring 27 closes an outlet port 17 causing flow through a bore in the piston 13, a chamber 28 and an adjustable throttle 31 to the valve. <IMAGE>
