Abstract: The palette-container (101) for liquids has an exchangeable plastic inner container (102), an outer shell (106) of lattice work and a palette (109) which is constructed as a bottom tray (110) and receives the bottom (111) of the inner container with positive fit, said bottom being constructed as a drainage bottom and having a filling nozzle (103) and an emptying nozzle (115) with a removal tap (105). Reinforcing beads (118a, 118b) are moulded into the bottom tray (110) which is adapted to the inclination of the drainage bottom (111), the bases (119) of the said reinforcing beads lying in a common horizontal plane (120-120). The flat bottom tray (110) has an outer support edge (117) extending downwards and is riveted or welded to a flat sub-base (121) or a sheet metal underframe in the region of the reinforcing beads (118a, 118b) and of the support edge (117) to form a hollow bottom with closed and/or open chambers (123) and a peripheral, outer, hollow support collar (124). 
<??>Due to the use of a flat bottom tray which receives the plastic inner container and has a flat sub-base or sheet metal underframe having hollow chambers and an outer, peripheral, hollow support collar, the palette is distinguished by a good damping capability and a high rigidity both in the case of oscillation loading due to gush oscillations of the liquid product in the container and due to oscillations transmitted by the transport vehicle and in the case of jolting and impact loading.

Filed: 1992-11-16
Abstract: A cigarette making machine is provided with a pressure drop measuring unit (1) located at or close to the garniture of the making machine. The pressure drop of a gas stream of constant volume is introduced into the compacted tobacco rod beneath the format finger (2) on the making machine at a point at which that pressure drop measurement correlates with the bound pressure drop of the finished cigarette. The unbound cigarette pressure drop or draw resistance experienced by the smoker can be calculated using the bound tobacco rod pressure drop obtained by correlation with the measured pressure drop across the rod in an algorithim processed by calculation means. The degree of ventilation of the cigarette may also be utilised in the algorithim calculation. Comparator means allows the unbound cigarette pressure drop to be maintained within pre-set limits by varying cigarette parameters which affect the overall unbound cigarette pressure drop. <IMAGE>

Abstract: A hearing aid is configured and dimensioned so as to be inserted past the cartilaginous part of the external auditory canal (external acoustic meatus) and into the bony part of the external auditory canal. The outer portion of the hearing aid fits snugly into the cartilaginous part of the external auditory canal; the microphone is located at the acoustic focus of the ear such that the natural sound and direction gathering functions of the human outer ear are fully utilized by the hearing aid. The inner portion of the hearing aid is articularly joined to the outer portion to enable the inner portion to be positioned past the sigmoid portion of the external auditory canal and forms a soft covered, elongated speaker which fits within part of the bony part of the external auditory canal, without causing discomfort to the human user. The hearing aid can be equipped with hand-held radio-controlled volume and tone controls (or a local, self-contained volume control), and it can also utilize a radio link to enable enhanced real-time signal processing of the incoming sound information via a remote processor. Additionally, the hearing aid can be equipped with an accelerometer to either cancel or enhance, depending on the human user's needs, conductive (through the bone) portions of sound information.
