Title: Membrane unit for reverse osmosis water purification appts. - with short feed water channels to prevent pressure drop and increase efficiency
Inventor: RAK STANLEY F
IPC: B01D63/10
Filed: 1975-02-05
Abstract: A membrane unit for an installation purifying liquids esp. water by reverse osmosis, comprising an arrangement of layers of a semi-permeable membrane, a porous product-water spacing material, a semi-permeable membrane and a porous feed-water spacing material, wound in a spiral on a hollow arbor, has the pores of the feedwater spacing material filled at points on the radius of the unit with an adhesive impermeable to water, and adjacent zones of the se semi-permeable membranes glued together. A channel extends through the unit and the adhesive filling the pores of the feedwater spacing material, into the bore of the arbor and is sealed at its outlet on the outer cover of the unit. There is thus an open connection to every layer of the product-water spacing material, whereas the connections between the feedwater spacing layers and the channel into the arbor bore are sealed. The arrangement overcomes the difficulties of falling-off in pressure along the long paths followed by the feed water through conventional units, and increases the efficiency of operation without expensive and complicated features.

Title: Variable setting plane for hydrofoil - with elastic mounting for self regulating setting on fixed support strut
Inventor: HOPPE KARL GUENTER DR ING
IPC: B63B1/24
Filed: 1975-07-11
Abstract: The profiled hydrofoil support plane is mounted at the bottom of a support strut to pivot about a transverse, horizontal axis. The pivot axis is near the nose of the profile and at a set distance from the centre of action of the upthrust force. The plane is elastically mounted to the strut with the spring attached away from the pivot axis to pull the plane into a steep setting. As the plane is dragged through the water the drag causes the plane to assume a more horizontal setting, with the upthrust automatically adjusted. Sudden water flow changes are thus dampened out without undue vibrations transmitted to the hull.

Title: Supervisory scanning system for telephone networks - sends interrogation signals between stations and provides four operating condition indicators
IPC: G08B26/00
Filed: 1975-08-05
Abstract: The supervisory scanning system for telephone networks is used between main exchanges and repeater stations and between repeaters and branch exchanges. A sequence of interrogation pulses is sent from the exchange to each repeater in turn. Each repeater interrogates its associated exchanges and if all operations are normal, the main control repeats the complete cycle. Each repeater sends out a pulse train via a linear gate (L1) and the return pulses from the remote station (NZ) are amplified (V), rectified and passed to another gate (L2) and linear mixer (M). The output of hte mixer is connected to discriminators (DU)(DO) which differentiate between 'no signal', 'normal' and 'alarm condition'. After amplitude detection, impulses are sent from a comparator to indicate one of four operating conditions.
