Title: Cultivating and harvesting mushrooms on spawned compost bed - topped with harvesting grill(s) and covering layer of soil or sand
IPC: A01G1/04
Filed: 1978-12-14
Abstract: Compost forms a confined bed in an open-topped box or bag etc. A harvesting grill is placed on top of a covering layer of soil and is overlaid with a supplementary layer of soil or sand, pref. to a depth of 0.5-1.0 cm. Pref. >=1 similar harvesting grill is laid immediately underneath the harvesting grill. Underneath this stack of grills there is pref. inserted a support grill with honeycomb rectangular apertures with sides 2-5 cms long and a grill depth of 1 to 5 cms. This is placed directly on top of the compost bed and filled in with sand or soil before the harvesting grill(s) is (are) applied.

Title: High current electromagnetic relay for safety circuit - has ferromagnetic screens mounted on high current conductor to prevent operation by parasitic currents
IPC: H01H71/32
Filed: 1978-12-22
Abstract: An electromagnetic relay in a safety circuit is sensitive to high currents and has a circuit excited by a large cross section conductor. Ferromagnetic screesn prevent operation by parasitic currents. A current whose intensity is being detected passes along a bias bar (1) covered by an insulating sheath (2). This bar passes through a magnetic circuit comprising a breech (3) and a moving armature (4) which is subjected to a return magnetising force from a magnet (6). This armature carries a contact (7) with which the operating contact (8) cooperates. Flat ferromagnetic screens (11, 12) located either side of the breech have an opening (13) which allows them to be mounted on the bar with a little play. These screens prevent parasitic fields from interfering with the magnetic circuit.

Title: Applying glazing coating to ceramic ware - using dry powder of specified electric resistivity in electrostatic field
IPC: B05D1/06
Filed: 1979-10-18
Abstract: Glazing is applied to a ceramic material by an electric field which applies the glazing in a dry state as a prepared powder in a size range of 80 microns and with an electric resistivity of >1010 ohm/m, pref. 1010-1013 ohm/m. The powder is prepared by enclosing the particles with methy hydrogen polysiloxane in a mass ratio of 0.1%, with an addition, to the coating material, to 5-10% of dibutyl tindilaurate or cobalt naphthenate. the powder is applied in an electric field at a voltage of 50 kV and the glazing is finally fired at 800 degrees C-1000 degrees C. This serves the two firing operations which are needed when the glazing is applied wet on a fired ceramic article. The new system thus saves up to 50% of the power consumption and over 50% of the glazing material per unit surface area.

Title: Laser beam tracking system - uses synchronous detector comparing phase of received beam and oscillator output to provide control signals operating motor to move mirror
Inventor: DAVILA CLAUDE
IPC: G01S17/66
Filed: 1979-10-31
Abstract: The laser tracking system includes a laser beam generator (1) sending a beam (2) via a plane mirror (3). The beam is reflected by the mirror to produce a cylindrical beam (4) directed towards the target. The mirror is rotatable about a pivoted joint (5) by electric motors (6). The motor input (7) is connected to the output of a servo system (8) via an amplifier (9). One output of an oscillator (10) producing a reference frequency (f) is also connected to the amplifier. Part of the energy reflected by the target is received on a beam (11) by a photodetector (12). The detector output is connected via filtering circuits to a synchronous detector (18). This compares the phase of the oscillator output and received beam in order to track the target. The beam has a variation in intensity across its width, the intensity decreasing from the central axis of the beam towards the outside.

Title: Drilling system using multiple tubes for treatment - uses tubes perforated at levels of strata for treatment inside pressure resistant tube
IPC: E21B43/12
Filed: 1979-11-13
Abstract: The system for drilling for water uses a number of tubes sunk through different strata until the required layer of water is reached, the tubes reaching different depths to match the contour. At the tops of the tubes are control valves, and suction can be applied to clean the perforated tubes from a remote position. Different tubes are used for treatment and development.
