Title: Liquophilic polyamide membrane filter media and process of preparation thereof
Inventor: PALL DAVID B
IPC: B01D65/10
Filed: 1981-10-13
Granted: 1986-03-27
Abstract: A process is provided for preparing skinless liquophilic alcohol-insoluble polyamide membranes by preparing at a first temperature a solution in a polyamide solvent having a temperature coefficient of solubility within the range from about 0.01 to about 5 weight per cent per degree Centrigrade of on alcohol-insoluble polyamide resin having a ratio CH2:NHCO of methylene CH2 to amide NHCO groups within the range from about 7:1 to about 12:1; inducing nucleation of the solution by controlled addition to the solution of a nonsolvent for the polyamide resin, under controlled conditions of concentration, temperature, addition rate, and degree of agitation to obtain a visible precipitate of polyamide resin particles which may or may not thereafter partially or completely redissolve, thereby forming a casting solution; spreading the casting solution on a substrate to form a thin film thereof on the substrate; cooling the film of casting solution to a second temperature sufficiently lower than the first temperature to precipitate polyamide resin from the casting solution; contacting and diluting the film of casting solution with a nonsolvent liquid, preferably containing a substantial proportion of the solvent liquid but less than the proportion in the casting solution, to precipitate polyamide resin from the casting solution in the form of a thin skinless liquophilic membrane; and washing and drying the resulting membrane; the alcohol-insoluble polyamide membranes obtained by this process have the unusual property of being liquophilic, i.e., readily wetted by organic liquids having a surface tension below about 60 dynes/cm, while being substantially not wetted by water, have absolute particle removal capabilities of the order of 0.1 to 5  mu M or more, and are useful as filter media for liquid systems in which such organic liquids are the continuous phase, as well as for separating immiscible liquid mixtures containing such liquids and liquids having a higher surface tension such as water.

Filed: 1985-11-15
Granted: 1989-10-05
Abstract: An electro-mechanical ventilator control mechanism comprises a rotary actuator (19) operable to move a control arm (1) to open and close the ventilator via a force transmitting member (10) formed in two sections (4, 5), normally retained telescoped one within the other by an electromagnetic device (2, 3) mounted on the section (4) and an electromagnetic keeper plate (4) mounted on the section (5), spring means (7) being provided pulling on the end of the member (10) and tending to open the ventilator. De-energisation of the electromagnetic device (2, 3) e.g. under the control of an automatic fire ventilating system, releases the keeper plate (4) and allows the ventilator to open under the action of the spring (7). Subsequent operation of the rotaray actuator (19) and re-energisation of the electromagnetic device (2, 3) re-sets the ventilator for automatic operation. Instead of a rotary actuator (19) a linear actuator (20) may be used.
