Title: Forming heat exchangers.
Inventor: O'NEILL CHRISTOPHER GERALD
IPC: B23K1/00
Filed: 1998-01-12
Abstract: A method of forming a heat exchanger from aluminium or aluminium alloy components. The method comprises forming the components, at least one of which is a tubular component (10), assembling the components, and brazing the components together. Said tubular component (10) is formed by bending a sheet bringing opposite edge portions (10a) of the sheet into overlapping relationship with one another, the gap (12) between said overlapping portions extending along said component. A bead (14) containing particles of brazing flux in a solvent is applied to the tubular component (10) along the exposed end (12a) of said gap, and an adhesive agent (16) is applied on top of said bead (14) so that the flux material is encapsulated. During the brazing the tubular component (10) is orientated so that the flux flows into said gap (12) and enables a brazed joint to be formed between the overlapping portions (10a).

Title: Creped hydroentangled nonwoven laminate and process for making.
Inventor: JACKSON WANDA WALTON
IPC: D04H1/46
Filed: 1998-05-18
Abstract: The creped hydroentangled nonwoven laminate material (10) of the present invention includes a creped hydroentangled nonwoven layer (12) attached to a support layer (14). The exposed, top surface of the creped hydroentangled nonwoven layer includes raised loop areas having low fiber density and high z-directional fiber orientation that are designed to receive and engage the hook elements projecting from a hook material. The raised areas (16) of the creped hydroentangled nonwoven layer are separated by non-raised areas (18) having relatively higher fiber density and relatively lower z-directional fiber orientation when compared to the fiber density and z-directional fiber orientation of the raised areas. The creped hydroentangled nonwoven loop laminate of this invention can be employed as the loop material of a hook and loop fastening system, such as used on disposable personal care absorbent articles. A process for forming a creped hydroentangled nonwoven laminate material also is disclosed.

Title: Gauge for thickness measurement of plated steel - uses ultrasonic probe at surface to produce echo from difference in crystal grain at interface
IPC: G01B17/02
Filed: 1980-05-21
Abstract: The method for measuring the thickness of plated steel, uses an ultrasonic test element in contact with the surface of the specimen, which emits an ultrasonic sound wave. The wave travels through the material, and is reflected back to the transducer from the lower internal surface, after which it is displayed on an oscilloscope, the position of the echo indicating the entire thickness of the material, this being proportional to the displayed length. The relationship between the scale and the time axis and the measured thickness can be calibrated, as a probe of known thickness is used, in which the sound velocity is constant. As a result of the difference in the crystal grains at the intersection between the plating material and the base material, an ultrasonic echo is produced, which is amplified and rectified, allowing the strength of the plating over the entire surface to be measured a technique previously considered impossible.

Title: Evaporative desalination of water - using split air stream for evapn. and cooling
IPC: C02F1/10
Filed: 1980-05-05
Abstract: Prodn. of desalinated water comprises evaporating water from an aq. salt soln. by contact with an air stream. The process is carried out in an appts. comprising a cooling zone and an evapn. zone, with heat exchange between the 2 zones. A primary air stream is passed through the cooling zone and is then split into a 2nd air stream comprising 20-90 vol.% of the primary air stream and a 3rd air stream comprising the remaining 10-80 vol.%. The 2nd air stream is contacted with the salt soln. in the evapn. zone until its moisture content is increased by 3.5-116 g/kg. The moist 2nd air stream is then passed to a condenser, where the water vapour is condensed by cooling with the 3rd air stream.. Since there is heat exchange between the cooling and evapn. zones, evapn. of water from the salt soln. cools the primary air stream, which conversely heats the salt soln.; thus, no external energy is required to effect evapn. and cooling.

Title: Winning chemical elements from sea water - using selective ionisation by concentrated solar photon beam and electrodeposition
IPC: F24S20/20
Filed: 1981-03-31
Abstract: The process is intended for winning chemical elements contd. in sea water by selective ionisation of these elements to produce their electro-deposition in an accumulator cell consisting of electrodes placed in the water.

The concentrator unit consists of two transparent plastic dished discs with a medium, e.g. a gas or water, between them. The spectrum of the concentrated photon beam corresponds with that of the target element. This is achieved by depositing a thin reflective layer of that element on the surface of the concentrator dish.
