Abstract: A digital computer performs a complete eddy current analysis of the tubes of a steam generator from data input to generation of a final report. The computer extracts signatures generated by various structural features and tube defects from the data, breaks down composite signatures into their component parts and classifies each such signature by applying thereto a cascading set of experience based rules. Signatures classified as structural features are examined closely for the presence of collocated tube defects. A post processor correlates the location of the indications so that the position of the defects can be presented in terms of distance from fixed structures.

Abstract: Apart from a carpet nozzle, a crevice nozzle (9) for cleaning places which are not easily accessible also belongs to the customary fittings of a vacuum cleaner. This crevice nozzle (9) should expediently always be ready-to-hand. In the housing (1) for a hand-held vacuum cleaner, this is achieved in that the crevice nozzle (9) is integrated in the housing (1). For this purpose, an opening (8) is formed in the rear end wall (6) of the housing, through which opening the crevice nozzle (9) can be inserted in a sheath which extends inside the motor space of the housing (1) in the region of the side edge (10) of said housing (1). The crevice nozzle (9) is held securely in the sheath by the upright operating position of the hand-held vacuum cleaner. <IMAGE>

Abstract: A film of magnetic recording media is covered with a protective layer comprising a sputtered zirconium compound. Advantageously, the zirconium compound is Zr0 2  and such a layer inhibits corrosion in the underlying magnetic recording media. The Zr0 2  layer is wear resistant and also exhibits reduced static friction. In one embodiment of our invention, an intermediate layer is sputtered onto the media and the Zr0 2  is sputtered onto the intermediate layer. Advantageously, the intermediate layer adheres strongly to both the media and the Zr0 2 . We have discovered that by providing the intermediate layer, static and dynamic friction between a read-write head and the disk tends to remain consistently low, and reliability of the disk is enhanced.

Both the lower projection and the upper projection are positioned to touch the lip and the lid, respectively. The lid can be moved from the container by positioning the lip in the recess and causing the lower projection to apply pressure to the lip away from the container and, at the same time, causing the upper projection to apply pressure to the tube at a position distant from the lip, in a direction towards the container.

Abstract: A spring accumulator (56) is used in conjunction with a modulation valve (30) to provide an operating mechanism for an hydraulic anti-skid braking system. The modulation valve includes shut-off valve means (44) to close off communication between an hydraulic pressure source (40) e.g. a master cylinder operated by the driver's foot, and a brake operating mechanism e.g. a wheel cylinder, and a modulation chamber (32) having a modulation plunger (35) which can move to vary the available chamber (32) volume and hence vary the hydraulic pressure in the chamber when the shut-off valve (44) is closed. The modulation plunger is connected to the spring accumulator (56) by a right-angle lever arrangement (63-61-64). The spring accumulator includes a movable plate (56) which is indexed by a pilot plunger (53) under the control of hydraulic pressure associated with the modulation valve (30). Work done by the outward displacement of the modulation plunger (35) can be stored as potential energy in the spring (59) of the accumulator and re-used to assist the return of the modulation plunger (35) to its resting state. The return movement of the modulation plunger is controlled by a small vacuum operated piston and cylinder (70) which can be of relatively low power as the spring accumulator (56) provides most of the energy required to balance the hydraulic pressure acting on the plunger. The right angle lever arrangement (63-61-64) and movement of the accumulator plate (56) allows the spring (59) to be locked in its compressed state (with the modulation chamber at low pressure) until activation of the spring is required to assist in returning the plunger to a higher pressure position.

Abstract: In a chemical analysis apparatus a controlled sample liquid is passed through a non-wetting porous membrane (23) in a diluter assembly (12) from a reservoir of sample liquid to a flowing stream of diluent which is constantly flowing. The sample liquid penetrates the membrane (23) under a positive pressure differential from the sample side of the membrane (23). Control is provided by varying the resistance to flow of the sample liquid, and the pressure on the sample liquid, as it flows through the diluter assembly (12). Passage of the sample liquid through the membrane (23) requires a minimum liquid entry pressure differential across the membrane (23) to cause enough penetration to give a detectable presence of the sample liquid in the diluent stream for analysis by an analytical detector (19).

Abstract: A method of forming a multi-colour chocolate product, includes the steps of applying a first colour chocolate into a chocolate mould (70) having a planar upper surface and recesses (70a) formed therein which form a sharp angle at the junction of the recesses with the planar upper surface; squeegeeing the first colour chocolate across the planar upper surface such that the first colour chocolate (72) fills the recesses and is scraped from the planar upper surface; permitting the first colour chocolate to at least partially harden; applying a second colour chocolate (76) into the chocolate mould on the planar upper surface thereof; permitting the second colour chocolate to harden to form the multi-colour chocolate product; and removing the multi-colour chocolate product from the chocolate mould. The chocolate mould is preferably formed by forming a negative plate (34) having an upper surface and recesses therein defining a pattern, such that the recesses form a sharp angle between the junction of the recesses with the upper surface; forming a positive intermould (54) from the negative plate; and   forming the chocolate mould from the positive intermould, with the chocolate mould having an upper surface and recesses therein defining the pattern, such that the recesses form a sharp angle between the junction of the recesses with the upper surface.

Abstract: A method for forming a metal layer includes the steps of forming an insulation layer (62) having at least one step portion on a wafer (48, 61); and forming the metal layer (63) over the insulation layer. The metal layer is formed by depositing aluminium-based alloy by sputtering while the wafer is heated to a temperature higher than that which produces a solid solution in the aluminium-based alloy. As a result at the step portion, a good step coverage can be obtained and the surface of the aluminium alloy layer is planarized. At the same time, the method according to the present invention contributes to a prevention of deterioration in the quality of the layer by preventing the formation of a silicon rich layer adjacent the insulating layer with interferes with a subsequent patterning process. The method also enables the deposition process to be carried out at a later stage.

Abstract: The shutter has a plug (18) whose plug-in part (24) is inserted into a circumferential sealing edge (32), and is to be so designed that the plug (18) is designed for simple production technology and uncomplicated, functionally reliable handling, yet results in hermetic sealing of the battery chamber (16), even after a battery (14) has been repeatedly exchanged. To this end, the plug (18) is manufactured in the shape of a flat hat of stiffly resilient material, so that it curves outwards against the direction of the axial application of pressure (33), for as long as the sealing edge (32) of the battery chamber aperture (15) engages in the vicinity of the cross-sectional plane of the end surface (21) of the plug facing the battery (14); while, when the plug is further pressed into the aperture (15) below the clearly identifiable cracking point, the flexural stress and hence the curvature are reversed, towards the interior of the battery chamber (16), and so, when the plug (18) is inserted, there is a manually identifiable certainty that the battery chamber (16) is now tightly sealed. In order to ensure an abrupt force reversal, despite the short axial structural length of the plug-in part (24) of the plug while it is pressed into the circumferential sealing edge (32), the plug pressure surface (37) on the actuation side is equipped with a recess (38). <IMAGE>
