Title: Sepn processes using hollow fibres - spirally wound on core to form cartridge of small cylindrical membranes
IPC: A61M1/24
Filed: 1973-01-02
Abstract: The fibres, which may melt, wet or dry spun, are first woven into a diagonal web. This is then wound onto a hollow, perforated former and the ends sealed by resin or other adhesive. One end is then cut off to expose its open ends of the filaments, and the cartridge thus formed is placed in a shell, one end being sealed by a circular seal. For reverse osmosis, liquor is pumped up the centre at high pressure and some taken away from the shell. Small molecules, such as those of water, permeate the fibres and run down out of the open ends. Thus the fibres from stable membranes which can be used for dialysis or reverse osmosis.

Title: Cellulose pulp mfr - using chlorine dioxide prepd in situ and recovering pure sodium chloride
IPC: D21C11/00
Filed: 1974-08-30
Abstract: Cellulose pulp is manufactured by contacting fibrous cellulose material with a mashing liquor contg. sulphide and NaOH, separating the pulp from the spent liquor which is then recovered and regenerated to obtain a white liquor, which is recycled to comprise at least a portion of the mashing liquor, Na2SO4 being added to the spent liquor to compensate for the loss of soda and sulphide. In this process, ClO2 is formed by reaction between NaClO3 and HCl in the presence of H2SO4, the mixture of NaCl and Na2SO4 being used in the recovery and regeneration operations to supply Na2SO4 compensating the losses in soda and sulphide and to add NaCl to the white liquor, the white liquor being concd. to deposit solid NaCl which is then recovered. The NaCl is recovered as a pure prod. and the Na2SO4 is reutilised as above.

Title: Battery charging cct. - charges in pulsations by comparing terminal volts with two refs. and controlling series switch
IPC: H02J7/02
Filed: 1975-02-19
Abstract: The battery charging circuit continuously monitors the potential difference between the batterys terminals when the latter is in the process of being charged. When this potential exceeds a first preset voltage, the charging current is switched off. When it falls below a second preset voltage the current is switched on again. In normal circumstances the charging process therefore continues in a series of pulsations whose duty factor decreases as the batteries voltage increases. The circuitry which does this consists of a Zener diode in series with a potentiometer across the battery; a transistor coupled to the potentiometers slider and controlling a transistor switch.
