Filed: 1987-10-02
Abstract: In a circuit for controlling the electric power for a load having a temperature control, in which a comparator compares a temperature-dependent voltage with a temperature desired-value voltage, detectors are provided for the positive half-waves, the negative half-waves, and the zero-crossing of the operating voltage, as well as a first memory to which are supplied the detector signals for the positive half-waves as setting signal and the detector signals for the negative half-waves as resetting signal. In addition, the circuit has a first and a second gate to which are supplied in each case the output signal of the first memory, the output signal of the zero-point detector, and the output signal of the comparator, the second gate receiving the inverted comparator signal. Furthermore, a second memory is provided, to whose setting input the output signal of the first gate is supplied and to whose resetting input the output signal of the second gate is supplied. The detector signals for the negative half-waves and the signal of the Q output of the second memory are supplied to a third gate, and the detector signals for the negative half-waves and the signal of the /Q output of the second memory are supplied to a fourth gate. Furthermore, the circuit contains a third memory to whose resetting input the output signal of the third gate and to whose setting input the output signal of the fourth gate are supplied...

Title: Pivotable lifting platform
Inventor: CELLA SERGIO
IPC: B66F7/08
Filed: 1987-12-30
Abstract: The invention relates to a pivotable lifting platform which is supported on a self-propelled truck provided with a control cab. The platform has six degrees of freedom which permit an extensive range of movement of the platform so that it can also be used for especially difficult and tricky situations. The six degrees of freedom are: horizontal movement in the travelling direction of the truck, horizontal movement transversely to the normal travelling direction of the truck, perpendicular movement, rotation about the smaller side, rotation about the larger side, rotation on its own plane about a perpendicular axis.
Patent DE-3804339-A1 (DE)
Title: Meat ejection mixer
Inventor: SCHMIDT EDWIN P
IPC: B02C18/30
Filed: 1988-02-12
Abstract: Meat ejection mixer for mincing machine which, as a rotating vane ring (1), effects the mixing of the product in the outlet chute and emptying of the latter, in particular self-fastening attachment of the meat ejection mixer. In known mixing paddles or strippers for this purpose, the fastening in front of the front perforated disc takes place by means of screwing to the cutter shaft, which is inconvenient, time-consuming, obstructive, unhygienic in the screwing region and possible only in the case of special cutter sets. The radially directed vanes of the latter are subjected to the thrust of the meat mass flowing out. The invention is to make possible the self-fastening. For this purpose, a magnetised hub (2) is attached in the vane ring (1), the projecting end (3) of which hub (2) produces a fastening effect on the cutter hub (13.1) of the mincing machine. The vane blades (5) are arranged opposite the vane beams (12) of the mincing machine cutter (13) on the outside (15) of the perforated disc. The vane blades cover, in a rotating and changing manner, perforation zones with the periphery of their body and interrupt the passage there so that no axial thrust results towards the vane blade (5). As a result of the vane blade arrangement and the magnetic fastening effect, additional fastening becomes unnecessary. Simple slipping onto and pulling off from the cutter shaft suffices for use in all types of mincing machine. <IMAGE>

Title: Method and device for evaluation of large-dimensioned operational interrelationships using operational characteristic diagrams
Inventor: SCHULTE ERASMUS DIPL PHYS DR
IPC: F02D41/24
Filed: 1988-02-20
Abstract: In a method and device for evaluation of a large-dimensioned operational interrelationship between a large number of mutually independent, freely selectable input quantities to be measured and/or specified and one result quantity, using operational characteristic diagrams, it is proposed that the large-dimensioned operational interrelationship should be decomposed into several small-dimensioned operational characteristic diagrams, each with a small number of input quantities and one intermediate result quantity, and that intermediate result quantities which are obtained from these operational characteristic diagrams are combined into one summarising, small-dimensioned operational characteristic diagram which forms the result quantity. It is thus possible to solve even operational interrelationships with very many input quantities using small, and therefore cheap and comprehensible, operational characteristic diagrams.

Title: Roughening machine for the nipping edge of a shoe unit
Inventor: JUNG KLAUS DIPL ING
IPC: A43D37/00
Filed: 1988-07-19
Abstract: The invention relates to a roughening machine for the nipping edge of a lasted-on and nipped-on shoe shaft, in which the shoe unit, consisting of last, insole arranged on the last bottom and shoe shaft drawn onto the last, is located on a holding device and in particular the nipping edge turned over onto the insole is roughened all around by means of a tool in order subsequently to be stuck together durably with a sole. To rationalise the roughening process, it is proposed with the invention, that the shoe unit is moved past the working region of the machine by a timed conveyor arrangement, the shoe unit is channelled out of the timed conveyor arrangement into the working region to be worked and is subsequently channelled back into the timed conveyor arrangement, or that the shoe unit is guided through the working region of the machine by a timed conveyor arrangement and the shoe unit is worked inside the timed conveyor arrangement by the tool while the shoe unit is situated in the working region of the machine.

Patent DE-3842834-A1 (DE)
Inventor: KROEHLING ERICH DIPL ING
IPC: F02N11/04
Filed: 1988-12-20
Abstract: In order to use a generator 2, which is connected to an internal-combustion engine 1 and drives an electric drive motor 5, as the starter for the internal-combustion engine 1 without providing additional auxiliary windings in the generator 2, it is proposed that current flow through the exciter winding 6 before flowing through the armature winding 8. While the voltage of the starter battery 13 remains essentially constant, it is thereby possible for the exciter field to be built up almost completely before a current flows through the armature winding 8 and produces a torque. A switching arrangement for such a method is also proposed.

Title: Method and apparatus for reducing the formation of condensation water in a chimney for a boiler with forced-draught burner
Inventor: GOEBEL WERNER DIPL ING
IPC: F23M9/00
Filed: 1989-03-17
Abstract: To reduce the formation of condensation water in a chimney for a boiler with forced-draught burner and with a flow shaft which connects the waste-gas conduit opening into the chimney to the combustion-air duct leading to the forced-draught burner and is arranged, with one end preferably constructed in the form of a hood, in the intake region of the forced-draught burner, air is conveyed out of the intake region of the forced-draught burner forcibly through the flow shaft. For this purpose, a second blower is used which conveys the air through the flow shaft for a predetermined period of time. This is carried out after the forced-draught burner has been switched off, but can also be effected with a time delay after the forced-draught burner has started.
