Title: Destructurized starch and process for making same
Inventor: DOBLER BEAT
IPC: C08L3/02
Filed: 1987-03-09
Abstract: A destructurized native starch material is described which has a water content in the range of about 10 to 25 % by weight and that its mass average molar mass is reduced by a factor of 2 to 5000 compared to its original mass average molar mass. The destructurized starch is produced by heating a chemically non-modified starch material having a water content in the range of about 5 to 25 % by weight of the total weight of the composition in the presence of a chain scission catalyst in a closed volume to an elevated temperature sufficient to form a thermoplastic melt and until the mass average molar mass is reduced by a factor of 2 to 5000.
Patent GB-2190573-A (GB)
Title: Plant watering system
Inventor: JONES DAVID WILLIAM
IPC: A01G27/00
Filed: 1987-04-23
Abstract: The plant watering system, which is for watering hanging plant pots has a body member (1) with a lower pot support hook (2) and an upper suspension hook (3). The body member has a lower part (4) and an upper part (5) which is slidably received in the lower part. The end of hook (2) is fixed to a piston (6) which is slidable under the influence of gravity in a blind bore (7) in upper part (5), resisted by spring (9). Upper part (5) has a cavity connected to a water inlet (11) and an outlet (12). Inlet (11) is sealed by a seal (22); when the weight of a pot attached to hook (2) exceeds the force of spring (9), the piston (6) moves down causing the seal (22) to cut off flow of water through the inlet. When the pot loses weight (because of loss of moisture), the spring overcomes the pot weight, moves the piston (6) upwards, releasing pressure on the seal (22), allowing water through the inlet, then through the body member and out through the outlet. The point at which the water is permitted to flow through the body member is calibrated, depending on the weight of plant pot attached to lower hook 2, by screwing lower part 4 up or down to adjust the tension of the spring. The change in weight in a pot attached to the hook can therefore be used to directly control the watering needs of the pot. The water flow may be controlled by a spool-valve or a pinch- cock system and the piston replaced by a diaphragm. <IMAGE>
