Patent DE-3204560-A1 (DE)
Title: Device for locking the movable counterclamping head of a sheet or section stretching machine
Inventor: KUTZ HEINRICH
IPC: B21D25/04
Filed: 1982-02-10
Abstract: In sheet or section stretching machines, the sheet to be stretched is clamped in clamping heads which are moved apart by hydraulic cylinder units. One of the clamping heads - the counterclamping head - is movable because of the differing lengths of the sheet to be stretched and is locked positively and nonpositively in various positions by means of force-transmitting pressure elements. The pressure elements are generally situated at the height of the sheet to be stretched, between the stretching clamping head accommodating the stretching cylinder and the counterclamping head. When the counter- clamping head is locked in the pressure elements by means of pins and holes, the spacing of the holes is relatively large, leading to increased strokes of the hydraulic stretching cylinder units. In order to avoid this, the pressure elements of the present sheet stretching machine have toothing on the upper and lower side, into which engageable or releasable locking pieces equipped with a plurality of teeth and arra nged in the counterclamping head engage. The coupling operation is effected by hydraulic cylinders by means of axially displaceable wedges connected to the locking pieces via guides. Various constructions to bring about the coupling operation are described.

Title: Atomising system for powdery spray material
Inventor: HESTERMANN GERHARD
IPC: A62C31/00
Filed: 1982-05-06
Abstract: Atomising system for electrostatic powder coating for atomising fine plastics powder, in which the air stream forwarding the powder particles is fanned out in a known manner to strike an impact body, and which operates with a supplementary air stream, to improve atomisation, which stream emerges from the back side of the impact body turned away from the powder stream and which crosses the powder-air stream. The special feature of the present spray system is that this supplementary air can be temporarily switched off or reduced by 70-90% by a switch directly fitted to the spray gun, and that the applied high voltage is reduced to a substantially lower value simultaneously with the reduction effected by switching off. Switching over effects a better penetration of the powder particles into recesses of the workpiece surface.

Title: Denture model and mounting sleeve for a denture model and process for the production of a denture model
Inventor: ZEISER MANFRED P DR
IPC: A61C9/00
Filed: 1983-01-19
Abstract: In a denture model which is detachably fixed via pins to a prefabricated base plate composed of a dimensionally stable material, where one section of the pin anchored in the model is guided in a drilled guide of a mounting sleeve which fits in the base plate, the intention is that the mounting sleeve has a conical design and fits into a recess, which is previously given a corresponding taper, in the base plate. This special mounting sleeve, whose drilled guide is designed for guiding, without play, a conical pin section, is thus detachably fixed in the base plate and can therefore be used again for producing other models.

Patent DE-3322566-A1 (DE)
Title: Screw-spindle drive for tool and workpiece slides
Inventor: JAKOB LUDWIG DIPL ING
IPC: B23Q5/40
Filed: 1983-06-23
Abstract: The invention relates to a screw-spindle drive for tool or workpiece slides which, in both directions of rotation of the spindle, interrupts the force flow between the spindle nut (2) and the slide (9) driven by this spindle nut (2) when a predetermined shear-force value is exceeded. After the force flow is interrupted, the axial movement of the spindle nut (2) relative to the slide (9) is limited only by the spindle length. After reversal of the direction of rotation, the positive-locking connection is restored automatically. The positive locking can be loaded by spring force, hydraulic force, pneumatic force or magnetic force. The characteristic of the positive- locking loading is preferably degressive. The clearest solution according to the invention is that loaded by permanent magnetic field and shown in Fig. 4. The flat faces (10) of spindle-nut mounting (3), stop ring (11) and housing (7) are held together by the magnetic circuit (18). If the movement of the slide (9) is hindered by excessive forces, the positive locking at the flat faces (10) separates. Depending on the direction of movement, the stop ring (11) remains either on the spindle-nut mounting (3) or on the housing (7). The anti-rotation locking means for the spindle-nut mounting (3), which anti-rotation locking means is necessary for the re-engaging in the exact position during the reversal of the direction of rotation, has not been shown, because it is state of the art. <IMAGE>

Title: Hydraulic press
Inventor: SCHENK HORST
IPC: B30B1/32
Filed: 1984-01-28
Abstract: The invention relates to a hydraulic press for pressing fibre-reinforced plastic mats into moulded parts with two press cross-members which can be displaced towards one another by a long adjustment stroke and a short pressing stroke, one of the press cross-members executing at least the long adjustment stroke and being coupleable to lateral tension elements which transmit the full pressing force. In order to design such hydraulic presses to be shorter and more rigid without additional outlay on construction, and to achieve better guiding and centring of the two press cross-members, the two press cross-members (2, 3) are formed from a box-like supporting cross-member (6, 7) which is open on one side and from a pressing table element (8, 9) which inserted in the supporting cross-member (6, 7) and is supported there at two or more supporting points (10, 11). The pressing table elements (8, 9) are held centred in their supporting cross-members in four guides (30, 31, 32) or centring devices (41, 43, 44) which are arranged crosswise. The upper press cross-member (2) is displaceable by means of long-stroke adjustment cylinders (19) and can be coupled by frictional engagement to lateral tension elements which take the form of cylinders (4), by means of hydraulically loadable clamping sleeves (22). <IMAGE>

Abstract: In the air swirl outlet for air-conditioning installations, two possibilities are additionally created for the angular adjustment of the swirl blades. At the factory, the output angle (cold case) can be set to two or more different lever transmissions of the thermally influenced tappet stroke, so that the angular changes are of different sizes. At site, the output angle can be readjusted by turning the guide rods and the approach effected thus of the movable annular body which influences the blade pivoting to the pipe piece bearing the blade pins.

Title: Retaining device for electrical apparatuses
Inventor: SCHMALZL DIETER
IPC: H05K5/02
Filed: 1984-06-26
Abstract: The invention relates to a retaining device 3 for electrical apparatuses 4 which are provided with sliding feet 2 on their four corners. In the case of electrical and electronic apparatuses, assembly units are pivoted into different positions for maintenance. In consequence, the centre of gravity of the apparatus is displaced, so that these measures can lead to tipping of the apparatus. In order to reduce the risk of tipping, the invention provides that the base surface 1 of in each case two sliding feet 2 which are arranged one behind the other in the displacement direction be inclined inwards and upwards in an inclined manner with respect to one another in order to move the tipping point to the outer edge of the apparatus. The invention can be used wherever retaining devices for electrical apparatuses are equipped with adjusting feet. <IMAGE>

Title: Heat exchanger which operates according to the counterflow principle and only has one terminating box
Inventor: DICKS HANS PETER
IPC: F28D9/00
Filed: 1985-04-22
Abstract: Air/air, air/oil or air/water heat exchangers used today for internal combustion engines are exclusively designed according to the cross-stream or counterstream principle. Since these heat exchangers are integrated into the internal combustion engines, all users require compact, high-power heat exchangers. The present invention specifies a heat exchanger in which the exchange media are directed by the heat exchanger in counterstream mode with respect to one another. This principle results in a higher degree of efficiency accompanied by a more compact design since only one terminating box (Fig. 1) is required. <IMAGE>
