Abstract: The invention relates to a backrest support for a seating furniture, in particular for an office chair. In order to provide a piece of seating furniture having a backrest, in the case of which particularly simple and safe installation and removal of the backrest is possible, it is proposed to design the backrest support (2) in two parts, having a first support part (4), which is connectable to a second support part (5) without a tool, with a releasable connection being formed, wherein, in the assembled state, the position of the two support parts (4, 5) with respect to each other can be secured without a tool by means of a lock (6).

Abstract: Summary The invention relates to powdered pharmaceutical formulations which, in addition to carrier particles and particulate active ingredient which preferably adheres to the surface of the carrier particles, contains a mixing element, wherein the formulation fluidized in the carrier gas stream can contain the mixing element. Preferably, the powdered pharmaceutical formulation is packaged as a single dose, for example filled into a container as a single dose, for example in a capsule. The mixing element has a size of at least 1 mm to 10 mm in a first dimension and a size of at least 50% of the size it has in the first dimension in the other two dimensions.

Abstract: A method and an apparatus for rapid and efficient heating of polymer pellets in preparation for processing in a plastifier. For introduction of heat energy, a gas, preferably dried air, is introduced into the polymer pellets flow so as not to be in direct countercurrent thereto. The gas is preferably introduced in its still hottest state in a targeted fashion, for the purpose of rapid energy input, at a freely selectable location. This preferably takes place at the material output of the booster hopper. The gas is preferably conducted by way of cascades, which can be of a variable design, and flows through the bulk material at least twice. The speed of the flow can be influenced.

Abstract: A vacuum drawer for vacuuming food comprises a vacuum chamber (20) which can be closed in an airtight manner by a cover (21) which can be actuated and an installation unit (40) to which a vacuum pump can be connected. To be able to generate an external vacuum, the vacuum drawer comprises a connector part (41) which is releasably connectable to the installation unit (40) (FIG. 2).

Abstract: The invention relates to a sealing bar for a vacuum drawer for vacuuming food, having a base support which comprises at least one welding wire extending in the longitudinal direction over the surface, with the welding wire being fastened to the base support by means of a clamping connection at one side or at both sides.

Abstract: The invention relates to a sealing bar for a vacuum drawer for the vacuuming of food, having a base support comprising at least one heating wire as well as having a frame part with an integrated non-stick coating, wherein the frame part is releasably fastenable to the base support.

Abstract: A vacuum drawer for vacuumizing foodstuffs with a vacuum chamber is closed by an actuatable lid at least partly is made of glass, with the glass part of the lid having two or more laminated glass panes which are arranged to at least partly overlap each other face to face.

Abstract: Preforms with a neck region and a preform body and having an enlarged geometry in comparison with the cavity of the injection mold are produced by injecting a polymer melt into the mold with a geometry of the cavity in the mold such that the radial extent of an inner space in the preform body thereby produced is not greater than the radial extent of the inner space in the neck region, the preforms are removed from the open mold by a removal gripper, and the preforms in the removal gripper are inflated using positive pressure such that the geometry of the inflated preform body is larger than the cavity in the injection mold.

Abstract: The invention relates to a device and a method for producing preforms (14) with a special geometry, wherein the finished preforms have a neck region with a thread and a preform body, which adjoins the neck region and has an enlarged geometry in comparison with the cavity of the injection mould.

Abstract: An auxiliary device and a method for finishing and calibrating preforms that are removed from a multiple tool in an unstable shape, the calibration process being performed with compressed air immediately after removing and withdrawing the preforms from the multiple tool. Nipples that can be inserted into the preforms are provided with expandable press rings or sealing rings in order to seal the interior of the blow-molded part of the preforms. The compressed air is introduced via the nipples, the sealing process being performed by radially expanding the press rings or sealing rings in analogy to the closing process of thermoses, thus protecting the preforms from adverse forces. The sealing point can be randomly selected in the transition zone from the threaded part to the blow-molded part of the preforms. The interior of the blow-molded part is optimally sealed without affecting the form stability and dimensional stability of the preforms.
