Title: Clamping device - for retaining packed items on trays, e.g. glass containers for sterilisation
Inventor: STEYER JOHANN
IPC: B65D71/02
Filed: 1992-11-14
Abstract: Device for simultaneous horizontal tensioning and securing of containers (37) arranged tight packed on a flat carrier, for a treatment which will subject them to mechanical movement, consists of a square or rectangular metal frame, provided with a closure device at one of its corners. The metal frame is formed from square or rectangular box section beam (1), connected on the inner face to a profile beam (6) which is flat over at least the height of the box beam (1), and provided with an elastic covering of flexible material (9). This metal frame is provided at one of its corners with a closure (13) and at least on the corner diagonally opposite to the closure (13), or on all the three other corners, with a hinged corner connector (11) and at the remaining corners with rigid corner connectors (12). All corner connections (11,12) are formed of two fish-plates, or incorporate a linked pair of fish plates, that represent the continuation of the upper and lower containment faces of the box beam (1). Hinged corner connections (11) and rigid corner connections (12) between the upper and lower fish-plates, or upper and lower fish-plate pairs, are each attached to a pulley roller (5) rotatable about an axis (10), over which is a cable (4) running inside the box beam (1) connected at one of its ends to the closure (13) and at its other end to the other leg of the closure (13) carrying corner in a screw-threaded rod (15), rotatable from outside by a countersunk drive head (18) along with the cable (4) securing (16) tensioning device. Each of the metal frame forming box beams (1) possesses a telescopic joint situated at an equiv. position in all four sides, coupled by a slider tube (2), that is rigidly attached at one end to the boxbeam (1) and at its other end is arranged to slide on a smooth bearing surface (3) in the box beam (1). At each of the telescopic joints in the box beam (1) the profile beam (6) complete with elastic covering is provided with a gap (7) in the area of the joint, extending vertically from the upper edge of the profile beam (6) halfway down its height and from there extending horizontally for a distance equal to half its height, and terminating in a vertical continuation of the gap from half height to the lower edge. The profile beam (6) together with its elastic covering (9) is thus divided into two, independent from each other, parts, each of which is provided with an extension finger (8) overlapping each other in height and moveable in opposite directions, so that each of the extension fingers (7) is not connected with the box beam (1) after the telescopic coupling. USE/ADVANTAGE - Horizontal clamping frame for retaining containers, e.g. bottle/jars, etc. on a tray or pallet and which is subject to movement e.g. in a rotary steriliser. Reduced breakages, due to overtightening, thermal expansion effects; using a device which requires minimal time for installing and releasing.

Title: Use of the gamma-radiation back-scatter measuring method for determining the density distribution of derived timber product board
IPC: G01N33/46
Filed: 1993-03-26
Abstract: Use of the gamma-radiation back-scatter measuring method for determining the cross-sectional density distribution of derived timber product board, especially of chipboard and fibreboard in the course of continuous preparation. The measurement is carried out on an edge-forming section face. The cross-section of the measuring gamma radiation is small compared to the thickness or, in the case of multilayer board, to the layer thickness of the derived timber product board. The section face is scanned by the measuring gamma radiation in the thickness direction of the derived timber product board. The measuring gamma beams are directed onto the section face with an oblique angle of incidence and the back-scatter beams are received by at least one gamma-radiation detector in a back-scatter emergent-angle range which approximately coincides with or is smaller than the angle of incidence. A computer to which the gamma-radiation detector feeds the measured values, compares the measured values with stored target values which represent a measure for the density. <IMAGE>

Title: Device for setting the angular position of pipe pieces with respect to one another
Inventor: SCHNEIDER KLAUS DIPL ING
IPC: F16L27/11
Filed: 1993-06-30
Abstract: In order to set a desired angular position of pipe pieces with respect to one another, it is proposed to displace a pressure-exerting piece, which acts on protuberances of a bellows connecting the pipe pieces, by means of a clamping element, acting on the pressure-exerting piece, such that the axial spacing of the protuberances in the region of the clamping element is reduced. For example, use can be made here of a pressure-exerting piece which can be displaced radially by means of bolt and nut and has side surfaces located in the form of a V with respect to one another. This device requires a small number of components, which do not have many requirements as regards dimensional accuracy placed upon them.
