Title: Centralised moisture control unit for plant cultivation - has moisture level sensors multiplexed to single central comparator to allow individual control
Inventor: SCHMIDLIN RENE
IPC: A01G25/16
Filed: 1978-12-21
Abstract: The moisture control system is used in plant cultivation systems and allows individual control of a number of units over a central controller. A probe inserted in the soil responds to a change in capacitance due to moisture level. The capacitive change is detected by a bridge circuit and the amplitude of the output AC signal is a direct measure of moisture level. The signal is smoothed to provide a DC output. The DC measured values (17) are multiplexed (Sa1, Sb1, Sc1Sn1) to a single comparator (39). Ref. values provided by potentiometers (43) are also multiplexed to the comparator. The resulting outputs of the comparator are demultiplexed (Sa3, Sb3, Sc3, Sn3) to the relevant control valves (33) supplying water. The multiplexing operation is synchronised by a central unit (47).

Title: Recording of operator work periods - utilising coped data card which activates timing unit for measurement of periods worked
Inventor: SIEBER WALTER
IPC: G07C1/06
Filed: 1979-02-01
Abstract: A time clock for recording the start and finish times of an operator has the facility to allow a number of shift working modes to be automatically a accommodated. In particular the system is suited to use 'flexi-time' operating systems. The identification cards used have a number of punched holes that enable switches (2) and contact (9, 12) to be controlled. In the standby condition timing pulses (A) do not have any effect upon the timer relay (1), since the main switch (2) is open. When the operator card is inserted the switch is closed and pulses are counted. An alternative for use during flexi-time periods is provided by a card that causes the main relay (9, 12) to be switched. Pulses (B) are transmitted to the timer relay when a bistable relay is closed. Indicators (5, 6) display the status of the system.

Title: Texturising friction discs - have surface coating to prevent debris clinging
IPC: D02G1/08
Filed: 1979-03-29
Abstract: In the mfr. of the friction discs for texturising yarns, following a serpentine path through the disc assembly, the side surface of the discs are coated with an anti-adhesive layer. There is an adjustable cleaning unit located between the discs, close to the disc upper surface, with a gap between them which is less than the axial distance between two adjacent discs, and it can also be used as a safety mechanism to stop yarn winding round the disc hub. The shape of the cleaner matches the disc, and acts with the shrouding round the discs. The cleaning assembly is mounted to the friction disc assembly, and is coupled to it. The cleaner can incorporate blades, brushes or sponges, which apply flexible pressure to the surface of the discs. The system prevents fibre particles and other debris from clinging to the discs.

Filed: 1979-09-18
Abstract: Two flaps, which can pivot about in each case one axis (13a, 13b), are opened by the insertion contacts (16) during insertion of said insertion contacts (16) into the busbar or cable space and are closed again by a restoring force during withdrawal, are provided on the insertion-contact bushing opening (25) in the partition wall (26) of a high-voltage switching cell. The flap arrangement is intended to be constructed such that, with a pivoting angle of the flaps which is as small as possible, it is possible optionally to open or close a through-opening which is as large as possible. For this purpose, the two flaps (11a, 11b) which jointly cover the bushing opening (12) in the closed state can pivot out in opposite directions about pivoting axes (13a, 13b) which are essentially at right angles to the plane of the bushing opening (12). A touching-contact surface (15a, 15b) which runs obliquely with respect to the opening axis (14) is inclined such that an opening force is exerted on the flaps (11a, 11b) by the axially moved insertion contacts (16) during insertion. <IMAGE>

Title: Volumetric measurement of milk yield during milking - using electrode pairs closing height related circuits and display
Inventor: LEMMER HELMUT
IPC: G01F23/24
Filed: 1980-02-14
Abstract: A method and arrangement for determining the vol. of milk produced by cows during a milking session enable display of the vol. and measurement of the milking efficiency. Individual data for each cow are presented with sufficient accuracy for the farmer simply and without adversely affecting milking. As the milk level rises it causes a number of electrical circuits, each corresp. to a defined level, to be closed. The condition of each circuit is continuously monitored and displayed. The circuits are made by the milk bridging the gap between electrodes (15) immersed in it. The display may show the state of all closed circuits or just the one corresp. to the highest level. The circuits may be scanned periodically. Their switching conditions can be used to regulate control processes.
