摘要:
The invention relates to a device for holding tools (13) on machine tools, comprising a tool receptacle (1) and a tool holder (6). Clamping elements (4) are used for fixing the two parts. According to the invention, the device is configured in such a way that both the tool holder (6) of a first type and the tool holder (6) of a second type can be adapted. The tool holders (6) of the first type meet the HSK standard while the tool holders (6) of the second type, for the purpose of shortening the length, do not have any receptacle (11) for a clamping system as it is required for tool holders (6) of the first type.

The inventive iron comprises a water container having a filling orifice (5) which is provided with a rigid cap (7) having a closure face (71) visible through the orifice. The cap (7) consists of retaining means which are embodied in such away that a first vertical pressure on the visible face (71) of the cap opens the orifice (5), thereby indenting said cap retaining means into the orifice (5), whereby making it possible to fill the container with water. When said retaining means are released, the orifice (5) is closed by the action produced by a second pressure on the visible face (71) of the cap.

The invention concerns a steam iron comprising a water reservoir (1), a hydraulic circuit (3) connecting the reservoir (1) to an electrically heated vaporization chamber (23), the circuit including in series an anti-drip valve (4), and an adjustable drip element (5) capable, in a self-cleaning position, of opening allowing a free passageway and supplying water to said chamber. The invention is characterized in that the drip element comprises means for opening or maintaining open the anti-drip valve (4), when it is in the self-cleaning position.

A system is proposed that is made up of a tool holder 1, a collet 15 with a clamping nut 19, and a tool insert 27, in which the collet 15 and the tool insert are fixed and positioned on various function surfaces within the tool holder 1. Nevertheless, the clamping means are the same, namely a thread on the tool holder 1.

A tool support for tools on machine tools has a tool support receptacle and a tool clamping insert arranged in the tool support receptacle and receiving a tool. At least one clamping screw secures the tool clamping insert in the tool support receptacle. The tool support receptacle has at least one continuous threaded bore having an axis that is positioned angularly relative to an axis of rotation of the tool. The at least one clamping screw when screwed into the at least one threaded bore engages in a tightened state a radial circumferential outer surface of the tool clamping insert.

The invention provides an improvement to a chair which has a tiltable seat carrier (1) and a tiltable backrest (2) on the backrest carrier (5) which are forcibly coupled to one another, and to an individual adjustment of the tilt of the seat carrier (1) in relation to the backrest carrier (5).The improvement consists in the fact that there is provided on the underside of the seat carrier (1) a bearing block (10) having a slideway contour (14) and a vertical slot (13) in which the flange (9) of a lifting element (7) is mounted vertically movably, and the lifting element (7) has a substantially triangular collar (12) which slides on the substantially rectangular slideway contour (14) when the flange (9) moves vertically. This means that the tilt of the seat carrier (1) can be adjusted to be steeper or flatter by turning the lifting element (7), and the limit positions are completely stable. The possibility of automatic unlocking is ruled out.

In a method for production of membrane proteins or receptors folded into their native structure, first, proteins solubilized in a first detergent are provided. To induce folding of proteins into their native form, the first detergent is exchanged for a second detergent. Both for the first and for the second detergent, examples are shown.
摘要:
A work place arrangement particularly adapted for laboratory work is described. The work place arrangement comprises a workbench including at least one attached board, at least one drawer, at least one arm rest, at least one working instrument or work tool and supply lines for the working instrument or tool, in which:(a) the attached board is adapted to receive the working instruments or tools located in or on the attached board, and the supply lines for the working instruments or tools housed in the attached board,(b) the arm rests comprise a left half and a right half formed as a joint unit firmly affixed on the front side of the bench at ergonomic height below the bench top main work surface; and(c) including a suction device having a suction opening located in the arm-rests unit centrally thereof between the left and right halves of said arm-rests. In a preferred embodiment of the invention two or more work benches are joined to form a working landscape.

The invention relates to an extrusion blow molding machine (1) with at least one extrusion head (2) and with at least two sheet dies (3), arranged next to one another, for the extrusion of sheet-like plastic preforms (4), with a multipart molding die (5) for processing two preforms into an essentially closed hollow body, having a device for handling the preforms (4). The device for handling the preforms comprises at least two grippers (10), arranged next to one another on a common carrier (8), for receiving the preforms (4), the distance between the grippers (10) being variable.
