Patent ES-452323-A1 (ES)
Title: Heat exchange units
IPC: B22C5/08
Filed: 1976-10-11
Abstract: A heat exchange unit for delivery of moulding sand in foundries. The sand is heated or cooled, as desired, by contact in its fluidized state with a heat exchange surface. The delivery temperature may be thermostatically controlled. The unit is capable of intermittent delivery, fluidization ceasing when delivery ceases so that the sand in direct contact with the heat exchange surface insulates the bulk of the sand therefrom. Delivery temperature on recommencement is therefore substantially the same as before cessation. By-pass means may be provided to ensure delivery of sand in the event of malfunction of the unit or during maintenance.

Title: Two step shifting unit for internal combustion engine starter
IPC: F02N11/00
Filed: 1977-05-26
Abstract: The starter motor pinion is turned via a friction clutch and moved axially along a course threaded section of the drive shaft by a magnet to engage fully with the starter ring before the starter motor is energised by a relay.

Patent ES-481330-A1 (ES)
Title: Apparatus for regulating the speed of a member delivering or winding a yarn
IPC: B65H59/38
Filed: 1979-06-06
Abstract: The yarn is formed into a loop and a loop sensor monitors the variations in length in the loop of yarn. The variations in the size of the loop result from a difference in the speed between the speed of the yarn and the speed of the draw-off or delivery member. The draw-off or delivery member is driven by an asynchronous motor having a slip-clutch drive with an assembly for braking in response to eddy currents. In particular, a disc is connected to the motor and a magnetic field is applied to the disc, the magnitude of the field which is applied to the disc directly dependent upon the size of the loop. In the preferred embodiment, the regulation of the speed of a pilot roller of a winder as a function of the delivery speed of the yarn is accomplished.

Title: Solar evapn. for desalination of sea water, purificn. of effluent etc.
IPC: C01D3/06
Filed: 1982-12-06
Abstract: Liq. is drawn by capillary action into a porous mass, e.g. cellular concrete or granular material. An upper part of the porous mass is bounded by a perforated, inclined panel of which the other side is heat absorbent and pref. forms part of the lining of a glass-topped solar radiation trap. Liq. percolates through the heater panel and promptly evaporates, in part at least. The vapour moves in a current which passes into a condensing chamber, shielded from the heat and pref. located below the porous mass. The condensing chamber is pref. kept at a low level by surrounding it with liq. on its way to the porous mass for evapn. Apart from the top of the solar energy trap, the greater part of the installation can be buried below the surface of the ground. Liq., e.g. sea water, can then be drawn into the porous mass directly from the surrounding earth or sand. Such ingress of liq. can pref. be regulated and prevented by movable shutters. This process and installation are used for solar evapn. to desalinate seawater, to purify waste water, to recover minerals from soln. etc. The installation is very simple, inexpensive and will give trouble-free service over long periods.
