Patent DE-3242481-A1 (DE)
Title: Laser controller
Inventor: KREMERS ERNST
IPC: H01S5/0683
Filed: 1982-11-18
Abstract: The invention relates to a method, and to a circuit arrangement for carrying it out, for controlling the output signal of a semiconductor laser, and is characterised in that the peak value of the modulation current has a pilot tone superimposed on it, in that the pilot tone frequency is filtered out of the electrical output signal of an opto-electronic converter which receives and converts the optical output signal of the semiconductor laser, in that the pilot tone received in this way is compared with a reference signal and the comparison result is supplied to the modulation current as the control signal. This method allows good stabilisation of the peak current operating points of the semiconductor laser, the cost for fast components being very low. The superimposition of the second pilot tone is proposed in order to set the base operating point of the semiconductor laser diode.

Patent DE-3313936-A1 (DE)
Title: Indoor blower having a recuperative heat exchanger
Inventor: ADAM CHRISTOPH
IPC: F24F12/00
Filed: 1983-04-15
Abstract: Indoor blower having a recuperative heat exchanger (Fig. 1) in which fresh air flues (5) separated from one another by fins are led past room air flues (6) having a warm room air flow. The air flues (5, 6) are deflected by 180 DEG  in the shape of a U after half their total length, so that the particular air flows are led in the opposite direction. The result is a U-shaped arrangement of the heat exchanger in which condensed water collects in the lowermost part of the arrangement. This condensed water, which forms in the cold room air flue (6), is absorbed by the water-absorbing cover (9) and partly given off to the dry heated fresh air in the fresh air flue by the arrangement that the cover (9) covers the fresh and room air flues on the outside in the U-shaped deflection. The fresh and room air flues have effected a common central partition (8) by means of the U-shaped deflection. At the lower end of the blower having a heat exchanger there is mounted behind a flap a container (10) which collects superfluous condensed water. The ventilators (11, 12) both operate in each case under pressure, or suction, so that no pressure difference arises between the plurality of adjacent air flues in the region of the U-shaped deflection (7). Filter mats (18) which can be removed laterally from the box (13) for maintenance are arranged above the ventilators (11, 12). <IMAGE>

Patent DE-3327202-A1 (DE)
Title: Belt type spreader
Inventor: KULLIK EDWIN
IPC: B65G65/28
Filed: 1983-07-28
Abstract: In a belt type spreader which can move on running gear assemblies and has a superstructure which is pivotable about a horizontal axis (7) and comprises a stacker boom (5) and, if necessary, a counter-weight boom (6), and an intermediate conveyor (13), the intermediate conveyor is connected by its transfer end (12) to a traverse (10) in the region above the unit for transferring the bulk material from the intermediate conveyor (13) to the stacker boom (5) by means of a bearing (11) which can be pivoted in all directions, which traverse is mounted in the superstructure (5, 6) so as to be pivotable about a horizontal axis (9) and is pivotable about the said horizontal axis (9) by means of an actuating device (23). When the superstructure (5, 6) is pivoted, simultaneous pivoting of the traverse (10) means that horizontal displacement of the intermediate conveyor in relation to the substructure (2) can be avoided. In order to eliminate vertical displacement as well, it is proposed to displaceably mount the bearing (11) which can be pivoted in all directions in a guideway curved round the horizontal pivoting axis (7) of the superstructure (5, 6). <IMAGE>

Title: Trailer vehicle with front axle steering
Inventor: WIELSCHER BENNO
IPC: B62D13/02
Filed: 1984-02-16
Abstract: In a trailer vehicle, in particular lorry trailer, with front axle steering, having a front axle which is constructed as a pivoted bogie axle with a pivoted bogie and a live ring and with a drawbar which is joined to the pivoted bogie, the drawbar being made telescopic in order to vary the distance between the towing vehicle and trailer, the object is to be achieved of enabling the distance, when selected to be short, between towing vehicle and trailer to be increased when the lorry is going round a bend in such a way that it is ensured that the trailer will swivel through freely. The distance control is to be automatic here and to take place without additional steering transmission connections between towing vehicle and trailer. In order to achieve the object it is proposed that a master cylinder (19) which is effectively connected to the telescopic cylinder (17) of the drawbar and has a piston and a piston rod (20) should be attached to the trailer body in order to control the telescopic cylinder (17) of the drawbar in the pivoted bogie (14), the piston rod (20) of the said cylinder (19) being connected at its free end to the pivoted bogie (14) via a positive guide (21). <IMAGE>

Patent DE-3416407-A1 (DE)
Title: Thermal lifting element
Inventor: MUELLER CHRISTOPH
IPC: H01H37/36
Filed: 1984-05-04
Abstract: The invention relates to a thermal lifting element having a working chamber, which is bounded by walls and of which at least one boundary wall can be displaced or moved in the event of an increase in pressure in the working chamber. The working chamber is tightly sealed in operation and contains a predetermined volume of working medium. Furthermore, the working medium can be fed thermal energy by means of which the working chamber or the working medium can be brought to a temperature which is above the evaporation point or sublimation point of the working medium. The result of this is that, at the phase transition temperature, the working medium changes its state into a gaseous or vapour form. As a result, the pressure and thus the volume of the working chamber is increased, so that a useful lift is generated by the movable boundary wall. <IMAGE>

Title: Laundry spinner
Inventor: THOMAS OTTO
IPC: D06F49/04
Filed: 1984-08-16
Abstract: A laundry spinner having an electric motor which is held elastically in a housing surrounding it and on the upwardly facing drive shaft of which the flange of a spinning drum is arranged, and in which the opening of a cover engaging over the spinning drum is preferably to be prevented by a safety device when the spinning drum is running, is to be developed so that, even when there is a substantial reduction in the conventional dimensions, a drive motor which can easily be accommodated ensures favourable operating conditions as well as a simplification of the safety and braking arrangements. It was recognised as essential to provide for the drive a direct-current motor which can be designed as a series-wound or shunt motor and in which shunt properties, in conjunction with a constant field, can be achieved by exciting it by means of permanent magnets. Particularly on account of the high starting torque which can be obtained thereby, the direct-current motor is equipped with lateral supporting arms which are supported on rubber blocks connected to the bottom of the housing, the bottom itself being provided with footpieces having a long elastic shank.
