The wheel supports are pivotally movable relative to the base body between an extended position in which the wheels rest on a support surface and retracted position, the arrangement being such that when the base is disposed on the support surface the wheels are caused to adopt the extended position and when the base is moved clear of the support surface the wheel assemblies are caused to adopt the retracted position.

Abstract: Multi-sectioned arms are used as a basic mechanism for coupling the display and the base of a portable computer. With this mechanism, one single computer can support all of the following capabilities. The display can move continuously, relative to the back edge of the base, along any combination of up and down, backward and forward, and left and right directions. The display can be tilted up and down as well as sideway for viewing angle adjustment, and also set to portrait and landscape orientations. When the display is in conventional open or close positions, each arm can be folded and parked alongside and parallel to as well as away from the edge of the base. The arms can be detached from the computer. The base and the display can overlay each other in four ways. Finally, mechanical mechanisms for implementations of the arms and connections to the computer are presented.

There is also an anti-tipping mechanism. When the display is in conventional open or close positions, each arm can be folded and parked alongside, parallel to, and away from the edge of the base. The arms can be detached from the computer. The base and the display can overlay each other in four ways.

Abstract: A plastics processing machine, particularly an injection molding machine, with an operating unit, a machine controller, and a subsystem having its own dedicated control unit is described. The machine controller and control device each generate a screen display and can be operated via the screen display. The operating unit is connected or can be connected for data transmission to both the machine controller and the control unit. Both of the machine controller and the control unit can be monitored and controlled by reproducing the original screen output from the machine controller and the control unit on the display screen of the operating unit, where new information can be entered. The information entered on the display screen of the operating unit is then transmitted back to the corresponding controller or unit associated with the reproduced screen display where the information was entered.

Abstract: A mold clamping unit includes a mold height adjustment system having a length-adjustable threaded connection, comprised of a threaded spindle and a spindle nut which supports a platen of a molding tool, for stroke transmission and transmitting a locking force in clamping position. A clamping mechanism, which locks the spindle nut in relation to the threaded spindle and is selectively releasable for length adjustment of the threaded connection, includes a clamping nut, connected in fixed rotative engagement with and coupled for slight axial displacement in relation to the spindle nut, and an actuator, switchable between an active position, in which the spindle nut is braced with the clamping nut by a tightening force so that the platen is urged against the spindle nut, and an idle position, in which the actuator is released and which can be implemented irrespective of a stroke position of the drive mechanism.

Abstract: The present invention relates to a method for performing the clamping force relaxation in a clamping unit of an injection molding machine. During set-up of the injection molding process, one or more real pressure curves of the mold cavity pressure during the cooling phase are determined and a set-point curve is derived therefrom, which is stored in the machine control unit. In dependence upon the product properties and material properties the seal point is established on the pressure curve. Furthermore, the relaxation speed of the clamping pressure of the clamping unit is determined and it is specified, in dependence upon the seal point and relaxation speed, at which pressure on the reference curve the clamping force relaxation is started. During the cyclic operation of the injection molding machine the actual pressure during the cooling phase is determined and the pressure force increase is performed when the actual pressure has reached the set-point pressure that was specified during set-up.

Abstract: A nozzle contact device for guiding and clamping the injection nozzle for an injection unit of an injection molding machine onto an injection mold includes a linear drive for moving the injection unit back and forth, and a guide carriage which can be driven by the linear drive, with the guide carriage being articulated to the injection unit. The invention is characterized in that the axis of rotation of the articulation between the guide carriage and the injection unit extends horizontally, and that this axis of rotation and the injection axis are arranged on planes which are parallel to each other, preferably on the same horizontal plane. Rotary joints or flexural joints can be provided. In addition, the rear part of the injection unit, in particular a screw mechanism can be height-adjustable. As a result, the nozzle contact force is introduced into the injection unit in the absence of a bending moment. No tilting is caused between the injection nozzle and the sprue bush of the injection mold.

The process module includes one or more process boards providing a base range of input/output (I/O) connections for the machines to be controlled. The process module can be directly connected to the bus board and the wiring board by means of a plug of second or third type, and thus produces a bridge, i.e. a connection, between the bus and wiring boards, thereby reducing wiring required between these boards At least one control module, which assumes the control tasks for the machine, can be plugged into the bus board by means of a plug contacts of first type.

Abstract: In a method for making long fiber-reinforced molded plastic parts, a continuous stand-reinforced melt is injected into a mold, after the latter has been closed, causing the mold to open until a predefined compression gap has been reached. The injection of long fiber-reinforced melt into the mold is continued and the mold is closed again. After permitting the long fiber-reinforced melt to cool down, the mold is opened and the end product removed. In this way, fibers can be introduced in a comparatively gentle manner into the mold and distributed therein, and fiber breakage and formation of surface marks are largely prevented.
