Title: A method of growing plants, and a growing bag for use by the method
Inventor: AHM PAUL HENRIK
IPC: A01G31/00
Filed: 1981-04-15
Abstract: Growing of plants, whereby a growth substrate surrounded by a plastic film in the form of a bag is used for the growing of roots, whereas the plant stem extends through an opening in the bag, and whereby the growth substrate is continuously supplied with water containing the additives necessary for the growth of the plants, and the water leaves the bag through one or more openings in the bag at the opposite end thereof relative to the stem opening. This growing is carried out with the bag being substantially vertically oriented. The watering water is collected and recirculated. For this purpose a growth bag is used, which is formed by a plastic bag with an opeining for the plant stem at one end and one or more openings at the opposite end. The bag comprises a porous growth substrate being appropriately hydrophobic and containing no soil, and it is adapted and shaped for vertical suspension. The bag is made of a light-impenetrable, preferably light-reflecting material. By the method a quick passing of nutrient fluid past the roots is carried out, and crop-carrying plants such as tomatoes, cucumbers, pepper, melons and beans may be grown in a high yield. By the growing, the mutual distance of the plants may in a simple manner be adapted to the growing step of the plants.

Title: Optical system for a liquid flow absorption cell
Inventor: KELDERMAN HERMAN FREDERIK
IPC: G01N21/01
Filed: 1983-02-09
Abstract: An optical system is designed to form real images of both its field and aperture stops 21 and 22 at the two window boundaries 13 and 14 of the path through a cell 11. This dual stop imagery permits control of both size and shape of the illuminated space. If this space is made cylindrical, its volume equals the exact fundamental minimum required to transfer the available light flux over a given path length, without reliance on wall reflections. A marginal concentric clearance of the cell bore around the illuminated space serves to avoid interferences from the wall and any adjacent perturbed liquid layer. The embodiment shown is an analytical apparatus for detection of optical absorption in liquid chromatography and cell 11 is tubular and has an entrance 15 and exit 16 for flowing liquid. Hemispherical and hyper - hemispherical lenses may be used. <IMAGE>

Title: Burners
Inventor: BOYLETT WILLIAM FREDERIC
IPC: F27D99/00
Filed: 1983-11-04
Abstract: A gas burner for use with a second similar gas burner has a combustion air supply duct containing a heat store 19 (which uses the heat from exhaust gases) and an aspirating venturi 18 connected at one end to exhaust through a valve 21. With the valve closed air entering the venturi via pipe 20 at the throat is directed turbulently through the heat store to form a combustible mixture with gas from supply line 16. With the valve open, and the burner not ignited, the entering air sucks exhaust gases through the heat store and blows them out through the valve, the store thereby being heated.   A control system for two burners senses the temperature at the heat stores and uses this to switch over the gas and main combustion air flow. The aspirating flow of air is under the control of a pressure sensor in the combustion chamber. <IMAGE>

Patent GB-2143093-A (GB)
Title: Inverter-fed synchronous motor and generator
Inventor: BOLTON HUGH ROBERT
IPC: H02P25/02
Filed: 1984-05-04
Abstract: Inverter-fed synchronous motors suffer losses due to mismatch between the voltage waveform at the output of the inverter and the e.m.f. waveform generated within the motor windings. The motor described has magnets 11 and 12 extending over a wide arc and stator windings 21 which are housed in open slots 18, 19. Each winding subtends an angle less than 30 electrical degrees and is spaced by 180 electrical degrees. The gap between the rotor and the stator is less than 1/4 of the width of the entrance of the open slots. The wide angle of the magnets helps to match the waveforms and the magnet disposition and properties, together with the use of open slots, tend to facilitate the attainment of near-rectangular current waveforms. In addition by using a larger than usual number of stator phases the torque ripple of the motor is decreased. An inverter and microprocessor control for the motor are also described. <IMAGE>
