Patent GB-201021524-D0 (GB)
Title: Fouling control in membrane filtration processes by magnetic field induced membrane vibration
Filed: 2010-12-20
Abstract: The present invention provides a tunable, magnetically induced vibration system for fouling control in membrane filtration processes. A variable magnetic flux, generated by an electromagnet, acts directly or indirectly (via a magnetic or paramagnetic vibration rod tightly linked to the membrane element or module) on a (magnetic) membrane, membrane frame or membrane element, thus inducing its vibration. The vibration enhances shear-rate of the fluid to be separated near the membrane surface to control fouling in-situ without interrupting the filtration process, thus increasing membrane fluxes, reducing the down time of operation and reducing the cleaning frequency.

Title: Method and additive for improving the efficiency of a central heating system
Filed: 2012-11-28
Abstract: An additive is adapted to improve the efficiency of a central heating system. The additive comprises alkyl polyglycosides and may additionally comprise a corrosion inhibitor, a scale inhibitor, a sludge conditioner, a bactericide, alkyl polyglucosides and/or a non-ionic surfactant. The additive reduces the surface tension of water in the central heating system, thereby enhancing the nucleate boiling and heat transfer characteristics of the system. Also claimed is a method of dosing a central heating system with the additive, whereby the additive is dispensed directly into a bleed valve of a radiator of the system using a syringe. Dosing the central heating system with the additive produces a solution 140 having a surface tension smaller than that of water such that the solution forms microscopic bubbles 120 when heated in, for example, a heat exchange tube 100 of a boiler of the central heating system. This is beneficial over use of untreated water 14, which forms large bubbles 12 that act as a barrier to efficient heat transfer between the source of heat and the water.

IPC: C09C3/10
Filed: 1980-05-28
Granted: 1983-08-11
Abstract: A surface modified pigment formed from kaolin material and a process of producing same are described. The pigment consists of pigment particles of kaolin material, and on the surface of the particles a primary and a secondary layer are precipitated. The primary layer consists of an anionic Al2O3-SiO2 hydrate gel having a molar ratio of SiO2:Al2O3 of from 3 to 30 and is present in a quantity corresponding to from 2 to 15% by weight of SiO2, based upon the original quantity of kaolin material. The secondary layer consists of a polymeric binder which is bonded to the primary layer by hydrogen or ion bonding and which is included in a quantity of at least 2% by weight, based upon the original quantity of kaolin material. The pigment is prepared by dispersing the pigment particles in water and providing them, while they are dispersed, with precipitated primary and secondary layers. The primary layer of anionic Al2O3-SiO2 hydrate gel is precipitated by acidifying water glass with an aluminium salt and acid, and the secondary layer is formed by adding a polymeric binder, the primary and secondary layers being bonded to one another by hydrogen or ion bonding. The pigment is retained in aqueous dispersion until after application. The surface-modified pigment is intended for use in paper and coats of paint.

Title: Method and apparatus for normalizing the speed of an element
Inventor: LIN FRANK W
IPC: B41J19/00
Filed: 1984-08-25
Granted: 1988-06-16
Abstract: A speed normalization circuit for eliminating the need to fine tune a servomechanism, such as a daisy wheel printer, after manufacture, for example, in order to compensate for speed variations caused by tolerance variations throughout the manufacturing process and evidenced by variations in the actual print wheel speed and the actual carriage speed, is disclosed. In operation, when a restore sequence is called for (power up, remote restore, cover open/resume, check/resume), the carriage is restored to the leftmost home position and is then stepped three times by an identical amount (twelve increments, 1/120 of an inch per increment). The average value of the actual carriage speed for these three movements is determined and a compensation value is selected. If the carriage speed is too slow, the nominal speed value stored in a read only memory look-up table is incremented by a fixed value (i.e., plus one, two, or three units); if the speed is too fast, the nominal speed value is decremented by a fixed value (i.e., minus one, two, or three units). The compensation value is added to the nominal speed value during subsequent actual operation of the servomechanism. For the print wheel, there are two programmed movements upon restore, namely, one half rotation in each direction (one forward, one reverse) for a total of ninety-six increments per movement. The speed compensation value is calculated in the same manner. Other features are also disclosed.
