Title: Demineralised sterile water prodn. plant - operating by reverse osmosis appts. and ion exchangers
IPC: C02F1/44
Filed: 1972-11-24
Abstract: The water to be treated is subjected to reverse osmosis in order to obtain a first fraction of partly demineralised water and a second fraction of mineralised, non-sterile water; a portion of this is passed through an ion exchanger to give a third fraction consisting of demineralised water. This is then treated by reverse osmosis to obtain a fourth fraction of sterile, demineralised water; this can be used directly and constitutes the desired prod. A At the same time a fifth fraction is obtd. of non-sterile, demineralised water. A good yield can be obtd. of sterile and completely demineralised water. The process can be operated on an industrial scale by using batteries of the reverse osmosis appts., and with ion exchangers in parallel. Daily outputs of the order of 2000 m3 can be achieved. Sterility can be guaranteed because the semi-permeable membrance can retain any particle larger than 0.05 microns.

Title: Non-return valve electro-magnetic holding mechanism - retains plane of sealing disc aligned with forward flow
IPC: F16K1/22
Filed: 1973-04-05
Abstract: The sealing disc is mounted on a pivot and is counter-balanced by a weight on an arm. Fluid flowing in a forward sense pivots the disc until it is in line with the flow. At this point a stop on the counter-balance arm closes a microswitch which operates an electromagnetic brake on the disc pivot spindle preventing its rotation. The brake, having its electrical circuit in series with the hydraulic pump, is released when the pump stops. Reverse flow of fluid swings the sealing disc back to the closed position.

Title: Projector slide change mechanism - has pivoting transfer frame in slide carrier operated by sliding carrier
IPC: G03B23/04
Filed: 1974-04-30
Abstract: Slides (A) are contained between spring (9) loaded pressure plates (6, 8) and are transferred from one side (1) to the other (2) of the magazine by repeated operation of the transverse carrier (4). A frame (10) freely pivoting about an axis (11) is provided with ramps at top and bottom (12, 13). As the carrier is moved to the extreme right, a projection (4a) deflects the frame away from the slides, causing additional tensioning of the spring (9) by the pressure plate (8). This assists the slide to enter the viewing frame (5) and after projection, further operation of the carrier causes the slide, guided by the ramps (12, 13) to pass to the receiving part (2) of the magazine. The peak (13a) of one ramp (13) causes the frame (10) to rotate and allow the other ramp (12) to clear the projection (4a) ready for the next slide.

Title: Cable drum control system - drum swings about vertical axis to keep cable at right angles to drum axis
IPC: B66D1/36
Filed: 1974-05-24
Abstract: The cable winding drum (3) is operated with a system which swings it about a vertical pivot so that the cable (4) unwinds at all times at right angles to the drum axis. The drum is supported on a frame (2) mounted above a fixed plate (1) so that it can pivot about a point (5) behind the drum, so that arms along the side of the frame project into a U channel (6) access the front, so that pads (10, 11) on their ends engaging the inside of the channel keep the frame (2) horizontal. A speed reduction arrangement (19, 22, 23) connected to the drum drives a cylinder (24) at a reduced speed proportional to the drum speed to displace a rod (25) controlling a distributor to actuate a cylinder (14) which is pivot mounted inside the channel (6) to swing one arm of the frame to move the drum in the required manner.

Title: Control for direct-alternating current converter - compares actual and desired values of three varying signals
IPC: H02J3/36
Filed: 1974-07-25
Abstract: A device for producing a control signal comprises a source with at least three bipolar variable input signals. A valve setting device responds to a first set of two or more of the input signals which produces an output signal, from the first set, having the largest positive value. A second valve setter responds to this input signal and a second set of at least another of the input signals and derives a resultant error signal representing the largest negative value of the signals from a group of signals constituted by a selected signal of the second set and by the largest positive signal of the first set. A device connected to the second setting device produces a control signal responding to variations in the error signal.
