Title: Chocolate conching mixer - with drive motor speed control by power output parameter of motor
Inventor: KUSTER WERNER
IPC: B01F15/00
Filed: 1989-10-12
Abstract: A conching mixer for triturating and trowelling chocolate material in a trough has at least two reversible rotors with conching tools which cooperate with the conching surfaces of the trough.  At least one motor has a speed control system with a control signal input joined to the output of a measuring set-up for a power parameter of the motor. The motor (M) driving the two rotors (3, 4) in a conching mixer (1) with jacketed walls (2) has in the power supply a dimetal thermoswitch (S) with an adjusting screw (13) for the current input, in series with a resistor R1.  Temp. sensors (14, 14') measure the temp. of the chocolate and of the water in the jacket, respectively, as a measure for the motor power output.  The motor speed control includes a thyristor (T1) which is controlled by the unit (P) in accordance with signals from the switch (S) via the lines (L).  If the change-over switch (SS) is actuated, the unit (P') which is governed by the temp. reading replaces the unit (P).  Alternatively a microprocessor compares the motor current with a set value and controls the motor speed. ADVANTAGE - This is a safe way of preventing overheating of the chocolate material and of achieving an optimum throughput without redn. in quality.

Inventor: KUTSCHKER WOLFGANG
IPC: B21D5/04
Filed: 1989-10-26
Abstract: A process for the two-directional bending of sheet metal comprises the following stages: The bending cheek of a swivel press is laid on a first side of a sheet metal section which is bent about a predetermined angle in a first direction of rotation; the bending cheek is then withdrawn from the bent sheet in a first direction of movement prependicularly to its pivoting axis and pivoted further in the first direction of rotation until it lies against the second side of the sheet opposite the first; the bending cheek is shifted in a second direction perpendicularly to the first; after the bent sheet has been suitably moved between the lower and upper cheeks of the bending machine, the bending cheek is laid against the second side of the sheet, which is bent about a predetermined angle by pivoting the bending cheek in a second direction of rotation opposite that of the first. In the bending machine for implementing this process, the bending cheek is fitted so that it can perform both mutually perpendicular movements in the first and second directions of travel.

Title: Automatically repeating thermic timer - has contact coupling material expanding by heater to break contacts and switch off heater allowing material to contract again
Inventor: SIMMANK WILFRIED DIPL ING
IPC: H01H61/06
Filed: 1991-02-13
Abstract: A first time, T1, is started by switching on a temp.-dependent switch (S1). The latter is brought to its switch off temp. by heating of the coupling material (C) by a heater (H1). T1 is thus established as the start of the  heating from the heater to the switching off. The switch (S1) interrupts the power supply to the heater. The coupling material cools at a rate determined by the heat insulation (D) and thus the chemically coupled switch (S1). Upon reaching its switch on temp. the latter switches the heater on again and starts the same process to establish a time, T2, from switch off of S1 to its switch on. USE - Switching of external load, e.g. separate heating circuit lamps, pumps, relays, motors or ventilators. Regular flushing of urinals in public lavatory.

IPC: E03C1/04
Filed: 1991-03-15
Abstract: A sanitary fitting for installation in a part of a building, for example on the edge of a bath tub, comprises an inner part (3) of the fitting, which can be fixed to a mounting (2), with form-fitting, in a manner such that it cannot be twisted relative to the mounting (2). A threaded bush (23) is axially movable relative to the inner part (3) of the fitting, by means of a screwing movement, in a manner such that it projects to a greater or lesser extent beyond the mounting (2). A coupling part (28) is connected to the threaded bush (23) in a manner such that, although it is uncoupled from the rotary movement of the latter, it nevertheless follows the axial movement of the threaded bush (23). The coupling part (28) is secured against twisting on the inner part (3) of the fitting by form-fitting with non-circular contours. An outer part (4) of the fitting is pushed onto the coupling part (28), again with form-fitting by means of non-circular contours. With this structure, the distance between the lower end face of the outer part (4) of the fitting and the mounting (2) can be changed without it being necessary for the parts located underneath the mounting (2) to be accessible. <IMAGE>
