Title: Hydraulic percussive tool - has changeover valve for driving moving parts to and fro
IPC: B06B1/18
Filed: 1974-03-04
Abstract: Hydraulically operated reciprocatory mechanism includes a changeover valve which, in one position, makes hydraulic connections to drive the moving part or parts in one directin and at the end of the resultant stroke of movement is moved to its alternative position in which it reverses the hydraulic connections to drive the moving part or parts back in the opposite direction. At the end of this stroke of movement it is moved back againt to its original position. The changeover valve is moved between its two positions by hydraulic pressure acting on respective pilot pistons and controlled by the moving part or parts, this pressure acting on a relatively large area of the respective pilot piston, being applied just before the end of a stroke movement and leaking away to exhaust during the first part of the next stroke via a restriction through which fluid may be displaced during return movement of the pilot piston. The valve is held in position during the remainder of the respective stroke by hydraulic pressure acting on a relatively small area at the same end of the same pilot piston which is removed when the valve moves to its other position.

Title: Industrial drum or band filter esp. for waste waters - utilising compressed air to backflush filter cake from endless screen
Inventor: JACKSON PHILIP
IPC: B01D33/00
Filed: 1974-12-06
Abstract: An industrial filter for liquids is claimed, of the type in which the filter screen travels in a closed circuit via a filtration zone, a cake-removal zone and then back to the filtration zone, practice the screen is formed as an endless, travelling band or is fitted around the circumference of a rotating drum. Essentially, in the cake-removal zone, the screen is thoroughly cleaned by back-flushing thro. the mesh of the screen with a jet or jets of gas under pressure, partic. compressed air. The jet direction is substantially perpendicular or radial to the screen surface and should have some angular adjustment as well as adjustable spacing from the screen. The compressed gas can be treated with an agent such as chlorine a chlorinated product, ozone, acid etc. A filter for liquids, waste waters. Using a gas to detach cake from the screen instead of a liquid, usually water, means that recovered cake does not have to be passed thro. centrifuging or decantation processes to separate off backflushing liquid; this is particularly useful in recovery of sewage sludge. A rotary drum has a filter screen around its circumference and feed liquid is supplied to the interior of the drum to give a pressure head (Delta H) which urges filtrate through the screen. Above the liquid level inside the drum, a sludge pan catches filter cake back-flushed from the screen by the blast of compressed air from a jet. This particular jet has a narrow slot nozzle extending across the width of the screen.

Title: Forming false selvedge on woven fabric - by dividing selvedge yarns in guides controlled by cams to twist yarns together
IPC: D03C7/06
Filed: 1975-04-02
Abstract: A device for forming a false selvedge on a woven fabric includes two frames, supporting yarn guides and moveable along guide rods. At each end of the guide rods are abutments against which the frames are constantly biassed by e.g. a coil spring and the yarn guides are freely pivoted on one of the frames. The other frames is provided with cam surfaces, which when the two frames are continuously moved together act on the yarn guides to continuously close them together and separate them so that selvedge yarns passing through guide eyes are continuously twisted around each other to form the false selvedge. Compared with previous devices the mechanism is simple, less prone to wear and vibration, and less likely to cause yarn breakages.

Title: Negatively charged atmospheric ions produced by air freshener - using high voltage electrostatic charge to vapourise water as ionised mist
IPC: H01T23/00
Filed: 1975-08-05
Abstract: An air freshener works by producing negatively charged (or opt. positively charged) atmospheric ions. An electrostatic potential of several thousands volts, e.g. 8,000 to 10,000 volts, is applied directly to water or a suitable aq. soln., as it flows from the end of a capillary or perforation of about 0.01-0.1 mm. in insulating material. This nebulises the water as an invisible vapour. Flow through the capillary is assisted by adding to the water a tiny quantity of non-toxic surfactant. Liq. flow is pref. maintained by a slight hydrostatic pressure or by the action of an air operated diaphragm pump. The capillary can be replaced with a porous material such as sintered glass. Used for ionising air freshener for dwellings, hospitals, factories, canteens etc. It provides the intense ionisation and biological efficiency of corona discharge without its attendant disadvantages of ozone emission and the prodn. of oxides of nitrogen.
