Abstract: In a disk type data storage device wherein the firmware used to control the device is partitioned with a first portion stored in the control circuitry and a second portion stored in the reserved area of the disk surface, the replacement of one of the portions in the field may cause the drive to have different levels or releases of firmware that will not function together. This disables the drive until diagnosed and connected. The structure disclosed includes identifiers associated with the firmware portions and the provision of a copy of the firmware first portion as well as the firmware second portion on the disk. The firmware first portion on the disk is normally never accessed and is a version compatible with the firmware second portion on the disk. During the power up sequence, the identifiers are checked for compatibility and the sequence normally continues.

Abstract: A horizontal metal extrusion press has a pair of relatively stationary end plates spaced apart relative to a press axis and a plurality of spaced parallel tie rods extending parallel to the axis between the end plates, fixing same axially together, and each formed with a support face extending parallel to the axis and lying in a plane forming an acute angle with the horizontal and vertical and generally including the axis. A movable plate is displaceable axially between the end plates and carries a ram. A holder support is carried on one of the end plates and a cylinder carried on one of the end plates and braced against the movable plate for axially displacing same. Respective prismatic-section base bars on the support faces of the tie rods each have a generally vertical guide face and a generally horizontal guide face. These base bars are secured on the respective tie rods for limited movement radially of the axis.

Abstract: The invention relates to an apron conveyor whose mutually overlapping members, consisting of plates with side walls which connect vertically, are arranged on link chains and are partitioned in a way matching the chain divisions. The slats are provided in their overlap area on their oblique edges on one hand with a limb which points upwards away from the plane of the slat and, on the other hand, with an arched recess which covers the raised limb of the adjacent slat. According to the invention, webs connected to the side walls or formed by them are provided along the length of the side walls. These webs connect the chain links laterally. This arrangement allows the use of standardised link chains of which only one in each link pair must be provided with two holes (in particular threaded holes) for connection of the members to the webs.

Abstract: A subsea clamp comprising a drive member and an attachment member for location on respective ones of a first and second subsea structure. The drive member and attachment member can be wedged together by a locking member. In preferred embodiments the locking member is a collet with a deflectable end that can be moved longitudinally from a first position in which it is free to a second position where it wedges the drive member in the attachment member.

Abstract: A method for cleaning automotive or truck wheel surfaces. A cleaning composition containing an acid fluoride salt and having a pH of about 3 to 6.5 is applied to the automotive or truck wheel surface. The cleaning composition contains soluble salt in an amount which provides the composition with a molar ratio of soluble anion to hydrogen ion of about 3.5 or greater. This protects the wheel surfaces cleaned, including those of untreated aluminum, from corrosive attack by the acid fluoride salt.

Abstract: The specification discloses compositions and methods for removing particulate and greasy soils from painted and waxed surfaces without stripping the paint or wax. The composition comprises terpene and a surfactant. When applied to a surface as a concentrate, the composition effectively removes greasy and oily soils such as tree sap, tar, and other soils of this type which are typically difficult to solubilize using standard detergents. The composition can be diluted with cold water and applied to a surface to remove particulate soils. The composition and method are particularly useful for cleaning greasy and particulate soils from automotive surfaces.

Abstract: An aqueous cleaning composition is disclosed that is useful for cleaning wheel soils from surfaces of painted steel, painted aluminum, chrome, stainless steel, clear coated aluminum and plastic. The cleaning composition effectively removes organic and inorganic soils from these surfaces without pitting, etching or hazing. The cleaning composition is effective without scrubbing. The cleaning composition comprises at least one acid fluoride salt and at least one organic soil removing agent selected from the group consisting of detergents and organic solvents. The pH of the cleaning composition is from about 3.5 to about 6.0.

Abstract: This invention relates to a dual-purpose cleaning composition for removing dirt and grease from painted and waxed surfaces without stripping the wax or paint from that surface. The composition contains nonionic amide and anionic surfactants, along with at least one of a terpene or a fatty acid alkyl ester.

Abstract: In a plate belt conveyor for steep conveying in the overlapping region of adjacent plates (5, 6), a pocket (15) is provided which is formed by a seam (12) and an upward projecting leg (8) of the lower rear plate end as well as a roof-like arch (9) projecting over the seam (12) and the leg (8) with downward directed leg (10) of the front upper plate end. The rising flank of the seam (12) is concentrically formed with respect to the chain fulcrum (14) in such a manner that when the leading plate (6) is angled relative to the trailing plate (5), the pocket (15) firstly remains closed and opens only on a further angling of the plate.
