Patent DE-2902219-A1 (DE)
Title: Electrodynamic grader for particle classification - uses criterion of density and electrical conductivity, using AC magnetic field to induce eddy currents
Inventor: ZACHAROVA GEB KOVALENKO MAYA S
IPC: B03C1/23
Filed: 1979-01-20
Abstract: Theelectrodynamic separator for non-magnetic loose materials, such as ore or gold concentrates is based on interaction of non-homogeneous alternating magnetic field and eddy currents, induced in the electrically conductive parts of the material to be classified. The flow of the material being graded is directed into the region of the max. strength of the inhomogeneous alternating magnetic field to generate max. eddy currents that deflect the moving electrically conducting particles from the direction of introduction of the material. Additional electromagnetic forces are introduced, in order to grade heavy metal combinations. These forces oppose the force of gravity and increase the angle of deflection.

Title: Digital process for balancing current or voltage signals - has analogue signal digitised and stored followed by conversion for comparison
Inventor: HEIDUK RAUL B ING GRAD
IPC: G01R17/02

Title: Plastomer stretch deforming tool - with two plungers for workpieces with oriented structure
Inventor: ARNOLD GERHART DIPL ING
IPC: B29C43/36
Filed: 1979-06-12
Abstract: A tool, which can be built into conventional plastics extruder or injection moulding machines and is charged by them, receives a parison in its cavity. A piston mechanism at right angles to the feed ports moves the parison into the final mould into which it is expanded by stretch deformation. The thermal fixation of the parts is effected by suitable control of the temperatures inside the stretch defomation tool. The stretch deformation of specific parts, for example of teeth in gear wheels, results in a beneficial orientation of the plastomer structure, leading to greatly increased strength.

Title: Gearchange control for tractor - has time control for staggered servo brakes to reduce drag
Inventor: REIMANN PAUL
IPC: F16H61/70
Filed: 1979-07-04
Abstract: The gearchange control for a utility vehicle has a solenoid valve to control the servo brakes for the epicyclic gears, with a time delay to ensure that the brakes have sufficient time to grip before the torque is applied. The gearchange operates with pressure control valves. The time delay is especially useful for reciprocal driving, such as for front loaders, when switching from forward to reverse allows the gearchange components time to stabilise before applying reverse thrust. The system is intended to reduce wear and fuel consumption.

Title: Beet harvesting and cleaning machine - has endless conveyor discharging onto cleaning grid for transfer to adjustable angle delivery conveyor
Inventor: WESTPHAL HERBERT
IPC: A01D17/22
Filed: 1979-09-08
Abstract: The beet harvesting machine which also includes a sieving system for cleaning the lifted beets, has a conveying arrangement behind the sieving system. The lifting mechanism drives two lifting wheels with their axes of rotation at an acute angle to the ground, covering six rows of beets. These discharge into an endless conveyor which conveys the beets upwards for discharge onto a transfer conveyor which discharges them onto a collector vehicle. The endless conveyor forms a rectangle in a vertical plane, the horizontal top strand discharging onto a grid which slopes downwards, acting as a sieve, to discharge onto the lower end of the transfer conveyor. This not only slopes upwards, but it can be swung sideways to a required angle about a vertical pivot axis.

Title: Monitoring appts. for indicating losses of stored material - has level sensor and circuitry for discriminating between level changes due to demand or supply and those caused by e.g. leakage
Inventor: NICOLAI WALTER
IPC: G01M3/32
Filed: 1979-10-05
Abstract: The appts. comprises a level sensor (7) providing an electrical output the value of which is read into an instantaneous store at predetermined time intervals under the control of a timer. A pulse shaper is connected to the instantaneous value store and provides a pulse output indicative of the rate of rise or fall as measured by the level sensor. Alarm circuits operate in response to the output of the pulse shaper via respective threshold switches to indicate optically and/or acoustically unauthorised changes of level as measured by the sensor (7). An arrangement is provided for inhibiting the alarm circuit when the monitored liquid level is being altered by authorised addition to or subtraction from the stored liquid.
Patent DE-2941967-A1 (DE)
Title: Removal of outer shells of crustaceans - using rotating rollers with rotating catcher with arms over rollers to prevent untreated shells passing through
Inventor: SCHREIBER WOLFGANG DR
IPC: A22C29/02
Filed: 1979-10-17
Abstract: The external shell of crustaceous is removed by passing them along sets of rotating rollers between which there are narrow gaps. The shells are broken off the bodies of the fish and pass through the gap between the rolls. The shelled fish fall off the end. Mounted above the roller, is a distributor which consists of 4 arms projecting out around a central pivot. The arms reach down into the gap between the rolls. The arms are rotated and they pick up any shellfish which is tending to slip over another and thus pass through without being satisfactorily shelled. The distributor throws the fish back to the inlet from where it must repass down the roll. The process is to remove the shells from crustaceous esp. to recover. The system ensures a very low amount of shell being passed through with the flesh when processing small crustacea.

These two paths can follow one another, the pedal actuating the member after completion of the first one.
Patent DE-2945710-A1 (DE)
Title: Versatile internal wiring system in telecommunication exchanger - uses fine-core cable between main control and rack-mounted units
Inventor: BECKMANN JUERGEN DIPL ING
IPC: H04Q3/545
Filed: 1979-11-13
Abstract: Only a single set of cable cores (RS,TE,DE,WR,QE) is used for data flow from the central control system to the peripheral equipment (IVPn) and only one other set of cable cores (QS,AE,DS,TS,SA) for data flow in the reverse direction. The significant element is that not merely are data sent over separate cores (DS,DE) but also the clock pulses (TS,TE). This implies that the information speed is adaptable to the equipment concerned. Outgoing data (DS) reach all the peripheral equipment units simultaneously but only one selected unit is enabled to respond through address data on address lines (ADR) with individual output lines from a decoder (DEC) connected to individual units.

Title: Ion, atom, or molecule sensor - with bipolar transistor with perforated gate as sensor
Inventor: HOEFFLINGER BERND PROF DR RER
IPC: G01N27/414
Filed: 1979-11-22
Abstract: A device for the detection of the presence of ions, atoms and molecules in gases or solutions consists of a semiconductor substrate (1) with an insulating coating (2) (which can be designed as a pn-junction with reversed polarity in the substrate) and a conductive layer. (3)The latter has perforations so that the ions can come into contact with both coatings. If designed as an MOS transistor, the substrate includes doped regions (9) of the opposite conductivity as drain and source, and the perforated coating is used as the gate. The gases or solutions can thus reach the insulator boundary and produce under the gate a change of the work function which can be measured as a voltage, threshold voltage or capacitance change.

Title: Pressure cooker valve with radial outlet - has diaphragm ensuring controlled lateral steam outflow and manual control of valve
Inventor: KAJA ALEXANDER
IPC: A47J27/09
Filed: 1979-11-28
Abstract: The valve housing is formed by a resilient stud (1) of rubber, which is a poor heat conductor, which at one of its end sides has an inlet opening (3) while at the other end remote from this opening it is closed by a diaphragm. The inlet opening (3) is closed by the head of an axially displaceable valve body (4) whose end side which is remote from the head (6) controlling the nlet opening can be brough to abut the inside of the diaphragm facing the inlet opening. The stud has a radial outlet opening (11) and the diaphragm ensures that the steam always flows axially through the stud during the transition from the open to the closed position and vice versa so that the steam escapes through the radial bores in the stud in a controlled direction allowing safe handling.
