Title: Cultivation system for hot countries - uses cold water pumped from lake or sea as heat exchange medium for soft water circulated through greenhouses
IPC: A01G9/24
Filed: 1976-07-20
Abstract: A rigid pipe (7) conveys the water through a motorised pumping unit (9) and non-return valve (10) into a supply canal (11) surrounding the land under cultivation.

Title: Polyolefin electric cable insulation prodn. - by passing extruded polyolefin through a chamber contg. organic heat transfer liq. under pressure
Inventor: HOQUARD MAURICE
IPC: B29C48/91
Filed: 1976-10-29
Abstract: Freshly extruded cross-linkable polyolefin in cable insulation is cured and chilled by passing through an adjacent chamber filled with an organic liquid heat transfer fluid of >=3 bar. The chamber is mounted on the outlet of the extruder die and is surrounded by heated and cooled jackets in succession. Used esp. for mfr. of electric power transmission cables. Use of relatively high mol. wt. heating medium of low volatility and permeability avoids internal opacity and microvoiding of such sheathing associated with pressurised steam filled during chambers. The operating pressures and vessel ratings can be lower, e.g. 3-15 bar instead of 15-30 bar.

Title: TV screen simulated tennis game - uses sampling device for ball signals resulting from separator and counting system
IPC: A63F13/00
Filed: 1977-03-29
Abstract: The game representing a game of tennis is played on the screen of a television receiver, where a spot of light travels to and fro. This is formed by a video synchroniser, which is combined with two synchronisers controlled by the two players to represent the racquets, using potentiometers. A signal separator for the interlacing signal is used to extract the synchronisation signal from the video signal. A counting system increases each pulse line and returns it to zero.

Title: Glass coated with two resin layers - with inner thermoplastic or elastomeric layer and outer duroplast powder layer
IPC: C03C17/34
Filed: 1977-07-11
Abstract: Glass is given 2 coatings of synthetics, (a) an inner layer of a thermoplastic or elastomeric synthetic, and (b) an outer layer of a duroplast powder. The glass is esp. in the form of bottles or of flat glass, e.g., windows or windscreens. The coatings have good bonding strength, resistance to scratching and alkali, low frictional resistance, and good transparency, are not tacky when warm, and give protection against splintering. Use of solvents can be avoided. Waste powder from the application of the outer layer can be re-used. Energy is saved by application of the powder layer directly onto the hot surface from the first application. The thickness of the inner layer can be reduced to 15 mu, and the thickness of the outer layer can also be reduced. The coated glass remains transparent after breacking.
