1Methods for use of abrasive blasting for producing particular effects; Use of auxiliary equipment in connection with such methods
 Appl.No PCT/GB1991/001880 Applicant GEC-MARCONI LIMITED Inventor BECK, Richard, Anthony
Apparatus for cleaning underwater structures such as oil rigs (1, 2) which suffer from marine growth, rust, etc. Grit blasting is a known method of cleaning in such circumstances but this has certain disadvantages not the least of which is abrasion of bearings, seals and other moving parts of the equipment by infiltration of grit. In the present apparatus a slurry of ice blocks in water is projected in a jet (11) at the surface from a nozzle arrangement (10, 12) on a remotely-operated subsea vehicle (ROV) (3). There are various ways of providing the slurry: a) it may be formed completely up above and pumped down a house; b) water (6) just above freezing may be pumped (7) down a hose (4) to a refrigeration plant (8) to form ice blocks; c) ice blocks may be formed in the ROV from the local water; and d) ice blocks may be stored in the ROV (3) prior to its launch and dispensed at the time of use. The use of ice blocks reduces unwanted abrasion problems since the ice fragments tend to melt after impact.

 Appl.No PCT/DK1999/000411 Applicant VRIST, Jørgen Inventor VRIST, Jørgen
A machine which is able to strip bearing line and weight line from a fishing net. The machine is designated with two steering rolls in the front (1) where the net is led through. Via a lower guide rail (2) supported by an upper guide rail (2) the net will be led to a rotating knife (3) which will separate the nets from the lines. On the back of the machine there are 4 rubber rolls (4) which - by engine power - draw both net and lines free off the machine and it is now easy to pick up. The advantages of the machine are that it is able to increase the speed of which the net is stripped. Until now this job has been carried out manually with a knife but the separation can now be done by machine. Using the machine stripping net you can now obtain a capacity of 10-15 net per hour.

A shingle-pattern roofing sheet manufactured of sheet metal profile by means of bending or press-forming, the roofing sheet having an advantageous, durable and attractive appearance which is achieved by utilizing the strength and ductility properties of the raw material. The successive steps (2) formed in the sheet metal profile are winding with respect to the direct cross-section of the sheet so that the bending directions (3, 4) of the sides (5, 6) of successive bent steps (2) are essentially divergent, and that the bending angles of the respective sides are preferably chosen so that the step-like pattern can be created without stretching the material, so that every second step has a positive bending angle (α) and the rest have a negative bending angle (α).

The concentration of a polyacrylic acid in a solution containing polyvalent cations having a valence of greater than or equal to 3, e.g., Fe (III), which interfere in the conventional quantitative analysis of polyacrylic acid scale-inhibitors, is determined by initially adjusting pH of the solution to a value in the range of 0.5 to less than 2, and then quantitatively measuring the polyacrylic acid content in a conventional manner.

A fixture is provided for checking the continuity of a cable having wires running between terminals in two end connectors. The cable is designed so that a single path is provided by each wire and its associated terminals. The connectors are plugged into mating receptacles on the fixture which also includes an array of associated light emitting diodes and an array of pins. The user touches the stylus of a manually movable probe against each pin. Only the associated light emitting device will be energized if there is good continuity for a given path in the cable. Non energizing of the associated device or energizing any other device indicates a lack of continuity and the source thereof.

 Appl.No PCT/US1997/010992 Applicant ANDRITZ INC. Inventor KOHLER, Gregory, R.
An impeller (12) for separating a conveyed stream of material has a central rotatable shaft (12) with plural blades (47, 48) extending therefrom. The shaft and blades form a number of generally wedge-shaped material receiving recesses (64, 66) within the impeller. One set of spaces has baffle means (82) which are configured to direct material in this set outwardly from the impeller on the upstream side of the baffle means. Another set of spaces has guide means (76) which are configured to guide the material in this set of spaces outwardly from the impeller on the downstream side of the baffle means. The impeller is particularly useful for separating streams of particulates, such as wood chips, compressed shavings, or the like.

 Appl.No PCT/GB1982/000275 Applicant THE SECRETARY OF STATE FOR DEFENCE IN HER BRITANNI Inventor BARLOW, Geoffrey, Frederick
It having been noted that snow accretes almost instantaneously while supercooled water (ice) builds up in linear fashion, instrumentation is provided hereby which, by differentiating the signal from an ice-accretion probe (10), is able to distinguish between ice and snow accretion and signal to that effect. As a result a helicopter pilot for example can select the appropriate deicing modes and save energy and or deicing fluid.

A bathroom scale has a load receiving platform (1) on which a user can stand and display means (8). Weight on the platform (1) is transferred to a stainless steel force plate (3) mounted on a base member (2) and having double encastred beams (42) formed by cutouts (43). The beams (42) are supported on knife edge support members (52), and a plurality of piezoelectric strain gauges (44 to 47) are screen printed on an insulating coating on the beams (42) of the force plate adjacent the position at which the force plate is supported on the support members (52). Deformation of the beams (42) as a result of weight on the platform (1) produces electrical signals which are summed to form a composite load signal and the display means (8) displays the composite load signal as a weight reading. Summing the electrical signals from the strain gauges electrically, avoids many of the disadvantages and errors associated with scales which utilise a mechanical linkage to sum weight components.
