Title: Hydroponic plant cultivation using foam tube - having uniformly distributed holes for circulation of gases and nutrients
IPC: A01G31/00
Filed: 1973-08-06
Abstract: A root holder for hydroponic cultivation of plants comprises a foam tube whose walls have holes uniformly distributed over its entire surface. The ratio of the net tube surface area (excluding holes) to the total area of holes is pref. 3:1-1:2 (1:1). A thin coating, partially permeable to water, esp. a perforated plastics sheet, may be fitted outside the tube, opt. with a layer of hydrophobic soft foam, e.g. polyurethane soft foam, between them. Inside the tube, there may be a cylindrical support, either in the form of a perforated plastics tube or a metal coil, e.g. Al. To feed the tube, it is simply dipped in water contg. nutrients. When out of the water, the holes permit free circulation of air to the roots of the plants and the escape of gases from the roots. The holes also permit immediate access of the nutrients to the roots when the tube is dipped into the water.

Title: Process for the manufacture of a device making it possible to obtain multiple visual effects with microencapsulated liquid crystals
Inventor: CALANCHI MASSIMO DR
IPC: B44F1/08
Filed: 1977-09-30
Abstract: Several overlaid layers of microencapsulated liquid crystals are applied, each layer consisting of a mixture of liquid crystals which changes colour at a temperature which differs from that at which the other overlaid layers change. The numerals represented consist of segments (A1, A2, A3...), each segment consisting of differing layers of liquid crystals which change colour at the temperatures whose value brings about the appearance of the numeral consisting of the respective segments. The layers of overlaid microencapsulated liquid crystals make it possible to produce objects of use in numerous sectors, such as advertising, decorating or furnishing, and thermometers indicating numerous temperatures on a confined surface. <IMAGE>
Patent CH-561980-A5 (CH)
Title: Control for async. machines with static inverters - has separate regulation for inverter input voltage and rotor speed
IPC: H02P23/08
Filed: 1973-08-27
Abstract: The control system for asynchronous machines with static inverters has logic circuitry to control the inverter frequency. A sensor generates a speed signal proportional to the rotor speed and a regulating circuit generates a slip signal. The speed signal and the slip signal are passed to the logic to control the inverter frequency as a function of the rotor speed. The inverter input voltage is monitored and the slip signal altered if this voltage exceeds a given limit. This variation of the slip signal occurs independently of the regulating circuit which generates the slip signal, and is in a direction which adjusts the machine so that the input voltage deviation becomes zero.

Title: Deflashing device on a casting machine
Inventor: YAMAGUCHI TERUMOTO
IPC: B29C45/42
Filed: 1977-10-19
Abstract: This deflashing device is used for the direct deflashing of the casting part of an injection die-casting machine without additional manual work. A holding device (28) can be moved in front of the product (a) in the mould cavity (11) of the die by means of a piston rod (26). The product is then pushed into this holding device by means of ejectors (12) and the holding device, together with the product, is then moved in front of a punch (25). During the subsequent working stroke of the casting machine, this punch (25), which is connected to the moving die part (10), removes the flash and lugs from the product (a), the holding device serving as a die. During each working stroke, one product is produced and the preceding finished product deflashed. This increases production efficiency. <IMAGE>

Title: Cellulose drying process with heat recycle stage
IPC: F26B3/00
Filed: 1971-04-16
Granted: 1972-01-07
Abstract: The cellulose dryer is enclosed within a ventilated housing, and heated, humid, air exhausted from the dryer is fed to a heat exchanger to heat up air drawn from the ventilated housing which is then fed to the dryer. The humid exhaust air is then reheated and fed to a heat exchanger to heat up ambient air supplied to the housing for ventilation. The dryer has a low energy consumption, and heat energy can be recycled without filtering the air exhausted from the dryer.

Title: Reconstituted marble tiles - mfd to exact sizes using a cast (polyester) resin setting
IPC: B29C67/24
Filed: 1971-07-20
Granted: 1973-03-02
Abstract: Chips of marble are bound in a layer on a flexible support sheet using sufficient resin to withstand abrasive cutting of the aggregate into a series of tiles with rough cut edges and slightly smaller (by 3-4mm) in size than the required product. These preform tiles are then placed in moulds and sheathed with additional cast resin to form tiles of the required final size and depth. The paper or plastics sheet used as the flexible support may be retained as an integral backing for individual tiles. Pref, the initial cast is of polyester resin lightly loaded with grains of marble and the resin contains coarser particles. Method offers excellent reproducibility in the tile sizes without requiring machining and polishing treatments.

Title: Electromagnet mechanical needle selection - for circular knitting machine
IPC: D04B15/74
Filed: 1972-08-08
Granted: 1973-03-30
Abstract: An electro mechanical system of needle selection on a circular knitting machine has a number of discs which correspond to the number of selector jacks in a diagonal arrangement. On these discs are two pegs which act on the jack, if they are actuated by a further pivoted lever which is held by a magnet. The lever is moved by a curved cam, to correspond to the timing of the disc to the jack, (and gauge) onto the magnet. If not energised a spring returns the lever to its start position. The pegs are returned automatically to their start position by a curved surface.

Title: Air supply regulator for forced-draught boiler - has valve actuated by gas pressure sensor diaphragm
IPC: F23N1/04
Filed: 1973-09-25
Granted: 1975-04-18
Abstract: Burner air supply regulator for a gas-tight heating boiler with forced draught consists of a suction fan in a discharge duct for the flue gases and a pressure-tight housing which surrounds the chamber and is connected to the exterior by a fresh air inlet duct. A chamber of the housing is connected with a diaphragm directly via a duct to the gas inlet of the burner's nozzles. The diaphragm responds to pressure changes of the gas fed to the nozzle and acts on a valve which alters the amount of air for combustion. The amount of air is altered without changing the rotary speed of the fan impeller, and the air feed is proportional to the power supplied. The gas pressure to the burner, proportional to the power, is therefore the quantity that is used, to control the air supply.
