Abstract: A compact array of bottles are unitised by a single resilient sheet-like device positioned midway of the body portion of each bottle.  The device can include a loop or handle which extends upwardly from the plane of the location of the device on the bottles to a position which will provide a user or handler of such a package with a suitable handle, even though the device is situated directly adjacent the neck regions of the bottles. The device utilises a single sheet of resilient plastics flexible material which includes interconnected bands defining apertures equal in number to the bottles to be packaged, dimensioned to frictionally and resiliently grip the body regions of the bottle.  The outer rank apertures in the device are extended longitudinally while the apertures in the middle rank of the device are extended transversely.  This creates a carrier device which has a total length which is adaptable to the applicating machine.

Abstract: A variable gain analog to digital compression encoder apparatus and method is operational for 'on the fly' gain adjustments without introducing significant distortion or noise in telephone conversation. An incoming analog signal (9) is fixed gain (11) reproduced as a first stabilized mid-operating point analog signal (41). A second stabilized mid-operating point analog signal (42) is produced in inverse proportion to the first stabilized mid-operating point analog signal, in response to a signal (43) tapped along a signal division of a difference between the first and second signals. The second signal is compression encoded (13) at a predetermined rate to produce pulse code modulated signal samples (25). The tap may be varied (44) to change the encoding gain, at any time, in accordance with operating requirements of a telephone apparatus.

Abstract: The invention is a method for cleaning up contaminated soil containing not only different types of hydrocarbons but also heavy metals and cyanades which upon heating of the soil can form dioxin and benzofuran products. According to the invention the production of said products is prevented by keeping the wall temperature of the rotating furnace at a high level such that its temperature during the entire process is higher than the temperature of spontaneous combustion of the pyrolyses products of which at least the hydrocarbons bind the oxygen in the furnace. The oxygen content may be further influenced by the infeed of an inert gas and/or by adding an organic fraction such as humus.

Abstract: The present invention generally relates to the mounting of windows in a frame, particularly to the mounting of windows of a vehicle, e.g. an automobile, in the body frame work. The invention provides a window ready to be mounted comprising, along its edges, a first profiled bead of adhesive material, already cured and having the general cross section of an U-profile. This first bead is elastic but not plastically deformable. The first bead comprises in its interior a second bead of plastically deformable not yet cured adhesive material consisting of a substance chemically compatible to the material of the first bead. The second bead, serving as the real adhesive material, is protected from environmental influences e.g. by covering it by a protection foil which is removed just prior to mounting the window.

Abstract: The anchoring piece, which serves as a partial prosthesis for the replacement of a condyle of the tibial head (11), consists of a bearing element (1) for a plastic body forming a sliding and bearing surface for a femoral condyle, and of a fixing element (4). The latter has a blade-like stem (6) and a distal widening (5) which, from ventral to dorsal, extends inclined in the distal direction. On the dorsally directed front edges of the stem (6) and of the widening (5) there are cutting edges (8 and 9) which, upon implantation effected by driving in from ventral to dorsal, penetrate into the spongy tissue and compact the latter. 
<??>As a result of this design, the anchoring piece can be fixed on the tibial head (11) from ventral to dorsal, without it being necessary to manipulate the tibia in respect of its longitudinal axis. A still intact ligamentous apparatus is retained, since no ligament detachments need be carried out even during the operation.
