Title: Cross-flow microfiltration lime softener
Inventor: HSIUNG ANDREW K
IPC: C02F5/02
Filed: 1984-05-18
Granted: 1989-06-22
Abstract: A method for softening a fluid containing hardness constituents, comprising the steps: (a) mixing the fluid with sufficient amounts of a softening agent, and previously precipitated hardness constituents in a reactor to establish a softening reaction in the reactor for precipitating a substantial portion of the hardness constituents contained in the fluid; (b) removing a portion of the fluid and precipitated hardness constituents from the reactor as a slurry and filtering the slurry through a cross-flow microfiltration module containing at least one elongated filtration tube, whereby substantially all of the precipitated hardness constituents are removed from the portion of the fluid exiting from the module as filtrate; and (c) returning at least a portion of the filtered out precipitated hardness constituents exiting from the module to the reactor as the previously precipitated hardness constituents. Also disclosed is an apparatus for softening a fluid containing hardness constituents, comprising; (a) a reactor for mixing the fluid with sufficient amounts of a softening agent and previously precipitated hardness constituents to establish a softening reaction in the reactor for precipitating a substantial portion of the hardness constituents contained in the fluid; (b) means for removing a portion of the fluid and precipitated hardness constituents from the reactor as a slurry; (c) a cross-flow microfiltration module containing at least one elongated filtration tube for filtering the slurry to remove substantially all of the precipitated hardness constituents from the portion of the fluid exiting from the module as filtrate; and (d) means for returning at least a portion of the filtered out precipitated hardness constituents exiting from the module to the reactor as the previously precipitated hardness constituents.

Abstract: The pages of a book are bound to the cover with adhesive. The adhesive is solid at room temp. and a bar of the adhesive is placed in a mould (4). The mould has a convex floor with width and length corresponding to the spine of the book cover. The open cover is placed over the bar of adhesive and the cover and mould are placed in a press with a heated ram (16). The ram is pressed onto the spine of the cover and, as the heat from the ram melts the adhesive, the adhesive is pressed into the shape of the mould. The adhesive is thus provided with a concave surface to receive the edges of the pages of the book.

Title: Hydraulically damped mounting device
Inventor: WEST JOHN PHILIP
IPC: F16F13/00
Filed: 1986-02-06
Granted: 1989-06-01
Abstract: A hydraulically damped mounting device has two bushes (1, 2) connected together by an elongate bar (3). Each bush (1, 2) has a housing (8,9) containing an anchor point (4, 5) connected to the housing (8, 9) by a resilient spring (6,7). Each spring (6, 7), and part of the corresponding housing (8, 9) defines a working chamber (11, 13) for hydraulic fluid, the working chambers being interconnected by a passageway (14) in the bar (3). The working chambers (11, 13) are positioned in the housings (8, 9) so that movement of the anchor points (4, 5) in opposing directions causes a decrease in size of one working chamber and an increase in size in the other. This change in size causes fluid movement through the passageway, and this exerts damping on the movement of the anchor points. Thus, when the device is connected between two objects with each anchor point (4, 5) connected to a corresponding one of the objects, relative vibration of the objects, and in particular torsional vibration may be damped.

Abstract: The stabilising of piled-up soil (E) is performed by means of tubular reinforcing elements (1), which are laid in the soil. A flexible, tubular infiltration reinforcement (2), which is permeable to a binder suspension and is preferably produced from a geotextile, encloses a rigid feeding tube (3), which does not collapse under soil pressure. The aqueous binder suspension is fed to the infiltration reinforcement (2) through outlet openings (3a) in this feeding tube. The said suspension flows through the permeable infiltration reinforcement (2) and seeps in the direction of the arrows into the surrounding soil, where the binder solidifies. The reinforcing elements consequently serve at the same time for binder distribution and as a safeguard against tensile stress. <IMAGE>

If belt blowing furnaces are used, one furnace may contain a plurality of conveyor belts (7, 7', 7'') connected in parallel. Particularly favourable combinations of blowing agents and fluxes are suitable for the preparation of the activator. All the variants proposed contain silicon carbide and lamp black; a favourable example uses borax. The blowing process is carried out for from 5 to 15 minutes at temperatures between 750 DEG C and 950 DEG C. Granules, grit or foam-glass sheets are produced.
