Title: Removing ions from aq. feed soln. - using liq. membrane which permeates the porous walls of hollow fibres
IPC: B01D/
Filed: 1979-03-27
Granted: 1986-01-20
Abstract: Coupled transport process for removing ions (I) from an aq. feed soln. and depositing them in an aq. prod. soln. is as follows: the feed soln. is circulated within the lumens of a no. of hollow fibres (II) (internal dia. is not >100 mils; microporous walls of thickness is not >20 mils) while the pores of the (II) walls are filled with an H2O-immiscible organic liq. which contains a complexing agent (III). The aq. prod. soln. is circulated over the outer sides of (II), while an ion complex is formed between (III) and (I) in the aq. feed soln. By diffusion of the (III) - (I) complex through the organic liq. retained in the (II)-pores the ions (I) are transferred to the aq. prod. soln. and there liberated. In (II), the surfaces of the walls have a greater affinity for the organic liq. than for H2O, and this characteristic and the microporous nature of the pores results in a capillary action which retains the organic liq. in the pores.

Title: Developing grid electrode for photocopier - with bias and spacing of electrode varied with time during development
IPC: B41L/
Filed: 1974-12-11
Granted: 1978-06-20
Abstract: The photocopier has a perforated metal electrode plate spaced from the charge image, and through which the toner power is applied to the image. The charge modulation on the elctrode alters the flow of toner.

At the same time the spacing of the electrode from the charge image is altered gradually, in a controlled manner. The rate of change of bias, and spacing of the electrode are both controlled by a central control to ensure max. contrast copies.

Abstract: Problem: how to record and play back data at a high line density. Means for solving the problem: a DSV control bit determining/inserting unit (11) inserts DSV control bits for execution of DSV control into an input data string and outputs the data string including the DSV control bits to a modulation unit (12). The modulation unit (12) converts the data string with a basic data length of 2 bits into variable length code with a basic code length of 3 bits in accordance with a conversion table and outputs the code resulting from the conversion to a NRZI encoding unit (13). The conversion table used by the modulation unit (12) includes substitution codes for limiting the number of consecutive appearances of a minimum run to a predetermined value and substitution codes for keeping a run length limit. In addition, the conversion table enforces a conversion rule, according to which the remainder of division of the "1" count of an element in a data string by 2 having a value of 0 or 1 shall always be equal to the remainder of division of the "1" count of an element in the code resulting from conversion of the data string by 2.

Abstract: A tower structure for gas-liquid interaction produces a high level of rolling turbulence in a gas flow path that has low pressure drop. The structure includes a spaced plurality of vertically disposed wall members (26) in an upwardly directed flow path, the wall members having a staggered array of horizontally extending deflectors (28) protruding from facing wall members, the space between the facing wall members forming a series of converging and diverging chamber portions in which the gas flows generally perpendicular to the deflectors. Rolling turbulence is produced between apexes (40) of the deflectors (28) and the facing wall portions (32,34), the gas flow being offset toward opposite wall members at succeeding apexes. In one configuration, a liquid is transported within the gas flow, in contact with the gas, the deflectors inducing a high level of rolling turbulence in the liquid. In another configuration, the liquid is separate from the gas. In a further configuration, two liquid paths are provided, one in contact with the gas, one separate from the gas. In the configurations transporting a liquid not in contact with the gas, the deflector members are hollow for passing the liquid in close proximity to the gas.

Abstract: A signal overload circuit for use in e.g. a digital TV receiver includes a piecewise linear weighting circuit which weights samples of greater magnitude proportionately more heavily than samples of lesser magnitude. The weighted samples are applied to an accumulator, and the accumulated value over a field interval is compared to an overload reference value to generate an overload output signal which is combined with other gain factors for application as the common gain control signal to a common amplifier. The overload detector is coupled in a feedback loop around the common amplifier. In order not to defeat the function of the other gain factors, the overload detector is programmable and its sensitivity is made responsive to the other gain factors.
