Patent DE-3910660-A1 (DE)
IPC: B65F3/04
Filed: 1989-04-03
Abstract: In order to prevent the manipulation of switches, such as flap and acknowledgement signal switches, which are provided for the safety of the operating personnel, these switches are connected to a circuit monitoring device 25 which is electrically connected to the automatic control device 30 for the automatic emptying of containers, in particular waste containers, into collecting containers. This circuit monitoring device 25 issues a release signal to the automatic control device 30 only when the desired switching state of the switches 11 and 16 is present. Additionally, further safety switches can be provided, such as for example an upper and a lower reference switch 9 and 32. Moreover, the circuit monitoring device is also connected to a barrier switch 13 and designed to test the switching position of the gear shifting of the vehicle 22.

Title: Multi-cutter thread milling machine - has headstock with two or more cutters equispaced around circumference of workpiece
Inventor: HILDEBRAND RUDOLF
IPC: B23G1/32
Filed: 1989-05-30
Abstract: The output and productivity of a conventional thread milling machine are limited by there being only one cutter.  In the inventions two or more cutters are spaced equally around the workpiece circumference so that, for example, a three-cutter arrangement would produce a complete thread form in only one third of a revolution around the work instead of the full revolution normally required. Looked at in end view the machine consists of a bed and workstable (1,3) together with a headstock (2) which carries the milling head assembly for driving the cutters around the work.  The work, which may be bar or tube up to say 200 mm diameter is fixed to the workstable with its axis on the machine axis (8) and does not rotate. The thread milling cutters (10) are at the end of pivoted arms (6) which carry the drive to the cutter and can be radially fed  towards the workpiece.  Each cutter is offset axially according to the pitch of the thread to be cut. USE/ADVANTAGE - Multiple increase in output and productivity.

Abstract: A conveyor, to carry a thermoplastic film through the various processing points on a machine has a pair of conveyor chains with pointed bars which pass through the edges of the film; these bars are held by supports on the side facing the film, and the chains are driven intermittently round in guide tracks. The rods are fixed on to the rivet shanks in such a way that the latter do not project out of the surface of the rods, and their supports rest flat against the outer face of the rods. The figure shows a cross-section through one guide track (1) for a chain. It has slots to take the chain (2) which has rollers and is driven intermittently round the system. The distance between the two chains is adjustable to suit the width of the film used (8). The chain (2) has the pointed bars (9) on one side and these pass through the film (8). The bars (9) are so fixed on to the shanks of the rivets (13) of the chain (2) that the chanks (13) do not stand out of the surface (11) of the bars (9). Supports (12) are also fixed to the track (1) and the face of each support (12) fully covers that (11) of the bar (9) on the length of chain which conveys the film but not on its return. ADVANTAGE - The design significantly reduces wear on the components concerned.

IPC: H05B3/74
Filed: 1990-07-18
Abstract: A method is described for regulating and limiting the power of a heating plate made of ceramic or similar material, in particular a glass-ceramic cooking plate. In a heating plate in which the individual heating zones are in each case heated by a plurality of heating elements which can be switched and controlled independently of one another, it is provided according to the invention that the individual heating elements are switched and regulated independently of one another, by means of a plurality of temperature sensors which are independent of one another and are arranged in the region of the heating zone such that all the points of the regions which are significant for one load case, particularly local hotspots, are detected, in such a manner that the power distribution in the heating zone region is largely matched to the locally different heat extraction. This has the advantage that the heating system can be used optimally, while the thermal stress of the heating plate material is, however, reduced. <IMAGE>
