Title: Draped polyvinylfluoride film in solar energy capture panel cascade - to spread the water thinly and inhibit evaporation
IPC: F24S10/60
Filed: 1975-07-31
Abstract: Solar energy capture panels ('insolation' panels) involve a liquid heat transfer medium (water) cascading under gravity down sloping roof top panels, where the water passes through shallow passages beneath a transparent cover and is spread over the base of the passages by a draped flexible plastic film. Prefd. polyvinyl fluoride used for heat capture for water or space heating systems, pref. involving thermostat controlled pumps to interrup the cascade if the panels are too cool, e.g. snow bound. The spreading of the water film and the restriction of the depth of the water layer (to about 0.5 mm) by the draped film enhances the efficiency of heat collection by the water (a) from impinging radiation, (b) by transfer from the heat absorbant surface over which the water cascades. The water surface is covered by the film, inhibiting heat loss by evaporation. Simpler, cheaper and less prone to blockage than very shallow passages made with rigid walls for gravity or force fed cascades.

Title: Pick up bale arranging sled - has guides directing bales into compartments changed over by bales as each fills
IPC: A01D85/00
Filed: 1975-12-19
Abstract: The sled comprises a frame hauled behind a pick-up baler and divided into a number of bale compartments. It has guides directing the bales in succession (10, 11, 12) to the different compartments. These are changed over by the action of the bales themselves (25), so as to direct the latter to the next compartment each time one fills up. The bales can be released when all compartments are full so as to leave them behind in a set pattern. Hinged guides (10, 11, 12) can extend forward from each compartment, having actuating portions (13, 14, 15) extending into the respective compartments at an angle to the rest of the guide itself. Thus the last bale entering each compartment thrusts this portion sideways and swings the guide across to direct the next bale into the next compartment.

Title: Unit for recovery and reuse of heat - utilising heat exchange produced in evapn. and condensn. of fluid
Inventor: ABOURACHID JOSEPH
IPC: F28D15/02
Filed: 1976-02-03
Abstract: Heat recovery unit comprises a closed circuit contg., degassed fluid. The circuit consists of an evaporator, a condenser and connecting pipes. The level of the bottom of the condenser is higher than the top of the evaporator. The connecting pipes lead from the top of the evaporator to the top of the condenser and from the bottom of the condenser to the bottom of the evaporator. When the unit is operational the temp. of the evaporator is higher than that of the condenser. When they have a common temp. the level of the fluid is between the bottom of the condenser and the top of the evaporator. During operation, when the evaporator is surrounded by a current of the hot medium and the condenser by the cold, the evaporator becomes almost full of liq. and the condenser of gas. A small bubble of gas is maintained at the top of the evaporator and a small height of liq. in the bottom of the condenser. This helps to prevent carry-over of liq. from the evaporator or gas from the condenser. It is possible to use a battery of several heat recovery units to effect greater heat recovery. The unit can be adapted for use with solar energy. The evaporator is placed behind the energy receivers and the condenser, in coiled form, may be placed in a container of water - thereby heating the water. The system can be used for recovering heat from industrial plant and using it to heat air for workshops etc.
