Patent DE-2652660-A1 (DE)
Title: Electronic control for apportioning appts. for loose goods - corrects signal representing pre-required cut-off value using integrator output voltage
Inventor: WEBER JOERG DIPL ING
IPC: G01G13/285
Filed: 1976-11-19
Abstract: The electronic control is for apportioning appts. for loose goods. The weighing-out appts. is electromechanical, and the material flow is automatically cut off when a preset weight below the required value, the pre-required value is reached. This value is corrected in the one or the other sense when the weighed material is outside the tolerances. Automatic correction of the electric signal representing the pre-required value is made by the output voltage of an integrator. A current flowing in te one or the other direction is applied to the integrator in accordance with the actual weight exceeding the tolerances. It flows during a specified time interval.

Title: Controlling phase condition of material in crystallisation from melt - where photoelectronic circuit detects interface between molten and solid state
Inventor: MUNIC ILJA N
IPC: C30B13/30
Filed: 1976-12-21
Abstract: The phase condition of a material is controlled during its crystallisation from a melt, where the radiation emitted by the material is picked up by a photo-optical system, in which the amplitude/frequency spectrum of the electric output signals is monitored; the presence of a low frequency component (k) in the spectrum indicates the existence of the molten state. When component (k) is detected, the photo-optical system is pref. moved towards the solid phase and is locked when the component disappears at the liq. solid interface. The pref. appts. uses one or two photo-receivers mounted on a trolley which can be moved in two horizontal directions above the interface. The output of the photo-receiver is fed to an amplitude/frequency analyser providing signals which actuate a stepper motor driving the trolley. The frequency of component (k) is pref. 0.5-30 Hz. Used for the zone melting of metals or semiconductors growth of monocrystals; drawing profiled parts from a melt, and other uses. One example is the zone melting of Al.

Title: Electronic PID controller with saturation prevention - uses linear amplifiers to produce pulse width modulated output
Inventor: PROELS HANS DIPL ING
IPC: G05B11/28
Filed: 1977-02-03
Abstract: An electronic adjustable proportional integral differential controller with saturation prevention generates a pulse width modulated output signal directly without further specialized circuitry. This feature represents an improvement on existing similar circuitry described in the literature. An input error signal (XW) is fed via resistors (4, 11) to two linear amplifiers (3, 8), one a differential amplifier, connected in a feedback loop with a hysterises circuit (6) and three potentiometers (7, 913). These can be adjusted to alter the proportional band, reset rate and rate time of the circuit which automatically generates a series of pulses of which the mark to space ratio represents the appropriate PID function of the input signal (XW). An alternative form generating two antiphase output signals is also available.

Title: Domestic heat recovery system - circulates water through sun blinds or roller shutters to partly heat fresh water supply
Inventor: BIESTERFELDT HARALD
IPC: F24S10/70
Filed: 1977-02-21
Abstract: The domestic heat recovery system uses the heat from the sun's rays to raise the temperature of water in a tank in e.g. the cellar, for baths, washing, laundry etc. Any further heat for the water can be supplied by a conventional boiler. Roller shutters or blinds which are lowered over the windows can be of hollow construction so that water can be circulated through them. This water absorbs the heat from the sun and can be fed to the collector tank. The heating action can be improved by an absorbing layer on the outside of the shutter, and the conveying tubes can be insulated. The system can be used for garage doors, etc., and plastics or other material can be used. The system can be thermostatically controlled.

Title: Strain gauge mounting arrangement - consists of holes drilled in body transverse to direction of applied force
Inventor: BROSA ERICH
IPC: G01L5/10
Filed: 1977-06-07
Abstract: A rectangular body (1) which is subjected to a force applied to one face has one or more holes (2) bored into it, transverse to the direction of the force, to a region of the body at which it is desired to measure strain.

Title: Winding drum driven by variable speed motor - has also adjustable tension rollers to control torque
Inventor: LIEDTKE REINHARD ING GRAD
IPC: B65H23/00
Filed: 1977-09-13
Abstract: A winding drum (4) is driven by a motor (1) whose rotational speed is continually adjusted in relationship with the increasing diameter of the windings on drum(4). The motor speed is such that the drum shaft (2) rotation is always ahead of the actually present winding velocity. An adjustable tension roller (9), operated by a second control circuit, regulates the winding tension and thus the applied torque on the winding drum (4). A photo cell (12) monitors the gap between the tension roller (9) and the winding diameter so that its signals can be used for the tension roller control.

Title: Switching control for track guided vehicles - with offset lateral guide rails and programmed control circuit receiving signals from sensor rollers
Inventor: NIEMANN KLAUS DR ING
IPC: B62D1/26
Filed: 1978-04-22
Abstract: The road vehicle is guided on a special track in city centres using lateral guide rails sensed by lateral guide rollers(10). These are linked to the automatic steering for front and rear axles. Switching control is achieved by setting the guide rails back and allowing the sensors to extend to follow a programmed track. The offset guides initiate the auto steering, or operate trackside signals to adjust the steering to follow either the left or right hand guides and hence follow the direction change.
Patent DE-2824723-A1 (DE)
Title: Pressed stainless steel sink top mfr. - uses press tool to cut off excess metal to prevent puckering around corners
Inventor: REITTER ERHARDT
IPC: B21D22/22
Filed: 1978-06-06
Abstract: Stainless steel sink tops (10) are pressed out of sheet metal with a turned down flange (16) around the entire top surface. This turned down flange tends to pucker at the corners (17) which are usually produced with a relatively small radius. This puckering can be avoided by a special press tool which cuts off part of the flange in the corner region before folding it at right angles to the plane of the sink top (14). This removal of metal reduces the metal flow to the corner and so eliminates the usual puckering in that area.
Patent DE-2827904-A1 (DE)
