The invention provides a method of manufacturing garments or garment parts from a continuous web comprising feeding the web to an apparatus in which a tuck is formed in the web within the area from which the garment or garment part is to be formed, the tuck is secured at at least one location within the area to hold the tuck in place, the web is severed around the outline of the required garment part and the tuck is opened away from the location where it is secured thereby forming a dart or plea...

Photographs of the integral type, exhibiting the effect of parallax about both horizontal and vertical axes, are recorded on a spherically lenticulated film, or on a spherically lenticulated screen-film combination, by means of a modified type of camera. Light is admitted to the film by way of a rectangular aperture in the front of the camera instead of through the usual photographic objective lens. If the camera is held stationary during an exposure, the resulting photograph is pseudoscopic ins...

A method of completing a well by installing in the well a flow conductor, performing various operations such as cementing the flow conductor in the well bore, drilling out excess cement from the flow conductor, perforating the casing at desired locations, and the like, installing a liner in the flow conductor of smaller internal diameter than the internal diameter of the flow conductor to provide an internal seal surface and oppositely facing stop shoulders in the flow conductor, setting a packe...

A method of forming a pipe joint, which pipe joint is of the kind in which an external peripheral flange is provided on the pipe and a nut or other retaining device encircles the pipe so as to abut the flange (or a member in engagement therewith), which nut or retaining device can be engaged with a threaded or other suitably shaped part of the fitting to which the pipe is to be joined in such manner that the flange is trapped between the nut or retaining device and part of the fitting. The metho...

A thermodynamic power system, including in combination a membrane compressor comprising wall means which define an enclosure with a membrane or membranes in the enclosure dividing the same into inlet and outlet sides. Conduit means connect the inlet side of the membrane compressor to a source of gas. Each membrane is constructed so as to permit the passage of gas molecules from the inlet side to the outlet side and prohibits the passage of gas molecules from the outlet side to the inlet side. Co...

In accordance with illustrative embodiments of the present invention, techniques are disclosed for compensating acoustic well logging measurements for variations in one or more conditions of a well bore. More particularly, these measurements are compensated for variations in well bore cross-section, and well bore fluid acoustic impedance and velocity. These compensation techniques have particular significance in connection with systems of the type which scan a well bore wall by rotating a transd...

A hull of a ship comprises a plurality of longitudinally spaced transverse frames on which are mounted in succession, a first continuous skin, a plurality of spaced longitudinal ribs and a second continuous skin. The skins and ribs are assembled on the frames with the latter in inverted position, and the assembly is inverted when completed.

Methods and apparatus for applying coating materials to articles, using electrogasdynamic apparatus providing a flow channel having a dielectric boundary which has a length-/width ratio of greater than 2.5. Gas containing particulate coating material is ionized to create an electrical discharge field for imparting an electrical charge to the particles prior to passage through the dielectrically bounded flow path and thereby creating a high space charge potential. In special applications, a free-...

A method for folding a moving sheet along a fold line which is angled relatively to the direction of movement of the sheet is disclosed. The moving sheet is passed and folded over a round rod having its longitudinal axis parallel to the direction of movement of the sheet. An apparatus for carrying out this method is also disclosed.

Metallic components such as facing sheets and honeycomb cores of structural panels are brazed together by electroplating different metals on a first component in superposed layers, pressing a second component against the first component and heating both components to a temperature which melts the electrodeposited metals, and cooling said components while they are pressed together to thereby solidify the melted metals and bond the components to each other.
