A corrugated tube 30 has corrugated sections 33 in which a plurality of peaks 33a and valleys 33b are alternately formed. The ratio Wb/Wa of the peak longitudinal breadth Wa and the valley longitudinal breadth Wb, with reference to a base line BL established at a position midway in the height direction between the peaks 33a and valleys 33b, is 1.2 to 2.0. The valley 33b floor is formed as a straight portion 33c formed to virtually the same outside diameter along the longitudinal direction of the corrugated tube 30. The corrugated tube 30 stretches less under fluid pressure and has less bending rigidity, improving a better disposition.

A chemical mechanical polishing apparatus includes a platen, a polishing pad affixed to a surface of the platen, and a polishing head configured to retain and rotate a wafer while pressing a surface of the rotating wafer against the polishing pad. A first portion of the polishing pad that engages the polishing head proximate the edge of the wafer provides less rigidity than a second portion of the polishing pad that engages a portion of the surface of the wafer. For example, the polishing pad and/or the platen may have a recess or other cushioning structure positioned proximate a locus of movement of a portion of the polishing head that supports the edge of the wafer.

The lock member has a locking engaging projection portion for engagement with the lever and, at one end of the body, has a releasing operation portion for releasing the engagement of the projection. A first connection portion connects the other end of the body portion to the one wall surface while second connection portions are arranged on both sides of the releasing operation portion to connect the one end of the body portion to the one wall surface. The lock member further includes cable protective projections projecting from the surfaces of the second connection portions in a direction away from the one wall surface. The lever includes a cross frame portion having a concave portion formed in a position located adjacent the releasing operation portion when the lever is in the second position.

A method and apparatus is provided for bucking a magnetic field of known geometry and time variation by means of a plurality of bucking loops. It utilizes multiple loops, each of which is energized by an electric current that creates a magnetic field of the known time variation. The multi-loop field forms a bucking magnetic field that better opposes the spatial variation in the known magnetic field over a volume than can the magnetic field from a single loop. The present invention is useful in electromagnetic measurements, where the magnetic field of a controlled source transmitter must be annulled at a magnetic field sensor. It is particularly useful for cases where the magnetic sensor may move relative to the transmitter, such as in certain airborne electromagnetic measurements.

A gas purge valve comprising a housing fitted with an inlet port being in flow communication with a liquid outlet port, and at least one gas outlet member, a gas flow barrier associated with the liquid outlet port, a float member displaceable within the housing between a first position adjacent the inlet port and a second position adjacent the gas outlet The at least one gas outlet is fitted with an inlet prohibiting valve, and is sealingly engageable by a flexible sealing member articulated to the float member. Buoyant displacement of the float member into the second position entails sealing of the at least one gas outlet by the flexible sealing member.

The present invention refers to a suction valve assembly for alternative compressors. Said suction valve assembly comprises at least two suction valves (3) independent from one another and disposed at one same blade (1), wherein each of said suction valves (3) comprises a functional edge (4) intended for a sole suction orifice (21) of the valve plate.

A stabiliser bar (1) to counteract pitching movements in a vehicle cab (10) includes a suspension device (9) with a bushing (14) on each side of which lateral stops (16a, b) are arranged, made from an essentially elastic material, and bearings (17a, b) arranged on the outside of these. A washer-shaped unit (23a, b) is arranged between the bearings (17a, b) and the lateral stops (16a, b) and that unit has a diameter which essentially corresponds to the lateral stops' diameter. The washer-shaped unit (23a, b) is arranged to support the lateral stops (16a, b) in an axial direction and absorb any axial forces exerted by the lateral stops and to form an air gap (24a, b) between the stabiliser bar's supporting surfaces (22a, b) and the washer-shaped unit (23a, b), eliminating direct contact between the stabiliser bar's supporting surfaces (22a, b) and the lateral stops (16a, b).

The aim of the invention is to transform an initial packaging consisting of a flexible material such as roll film and sealed by at least two welded joints with a liquid substance inside, into a packaging having a cubic shape with at least three faces. The method and installation using a machine comprise the following steps:

• • 1—the initial packaging is blocked and immobilised by means of subjection clamps which maintain a constant pressure at all times, towards the inside of the initial packaging, but with regulatable damping;
  • 2—an impact clamp (6) hits any of the perimeter lateral side or sides of the initial packaging head-on, so that the packaging inflates, thereby taking on the cubic shape, and the flaps are created; and
  • 3—the flaps are then sealed and cut. The most significant advantages of the invention are that very small cubic packagings can be produced, and at the same time the logistical costs are reduced as a result of the absence of flaps.
