Abstract: The invention provides an apparatus for separating components of a fluid stream comprising a first centrifugal separator and a further separator; the first centrifugal separator comprising: a support structure and a centrifugal separator unit rotatably mounted on the support structure so as to be rotatable about a rotational axis extending through the centrifugal separator unit; a drive element for driving rotation of the centrifugal separator unit; wherein the centrifugal separator unit comprises a centrifugal separation chamber having an inlet which is connected or connectable to a source of fluid requiring separation, a first outlet for collecting a higher density component of the fluid stream, and a second outlet for collecting a lower density component of the fluid stream; the first outlet being connected or connectable to a first collector for collecting the higher density component and the second outlet being connected or connectable to a second collector for collecting the lower density component.

Abstract: The present invention is a small universal smart phone stand that can fit on a key chain. It can stand a smart phone to custom viewing angles. It transforms from flat into a custom smart phone stand, by just bending two flaps. When the flaps are bent, it creates a gap in-between them. This is where a smart phone is held. One flap is the front support, the other is the back support. The angle of which the flaps are bent into, adjusts the angle of the smart phone. The present invention is made of a shape retaining material. That allows the flaps to retain the shape they are bent into.

Abstract: A method and apparatus are provided for engraving semi-soft and malleable items such as soaps and candles, to create large quantities of personalized products where each item could have unique markings, such as a monogram, logo, word, or saying. Embodiments include a machine tool having a spindle, a stylus, and a nosecone comprising a top portion attachable to the spindle. The nosecone also has a bottom rim for contacting stock to be machined by the machine tool and for distributing a downward pressure of the machine tool applied to the stock; and a body between the bottom rim and the top portion, for preventing contact between the stock and the spindle and for preventing a stylus of the machine tool from penetrating the stock before a predetermined amount of pressure is applied to the stock from the machine tool. A holding device of a rigid material, having at least one nest cavity, holds the stock while the pressure is applied to the stock.

Abstract: A locking arrangement for a row of radial entry blades (62) of a turbo-machine. A closing blade (66) includes a root portion (74) having an axial attachment shape (78) for engagement with an axially oriented slot having an axial attachment shape (76) formed at the entering slot location (34) of the radial entry rotor disk (56). For applications utilizing blades with curved platform faces (112), a preceding blade (108) and a following blade (110) in the row are designed with one curved face for abutting adjacent radial entry blades and one flat face (120) for abutting the flat closing blade faces (116). The closing blade (84) may be designed with a root portion (88) having two legs (90,92) that are urged apart by a key (86) into tight contact with the adjacent blades.
