Patent ES-413754-A1 (ES)
Title: Method and machine for manufacturing shaped parts from flat sheet metal
IPC: B21C37/16
Filed: 1973-04-16
Abstract: A method for the manufacture of shaped parts of elongate shape and having a variable cross-section from a strip of flat sheet metal. The method is characterised in that the strip of sheet metal is displaced along a generatrix of a shaping mandrel whose cross-section varies progressively along this generatrix in predetermined manner by decreasing dimensions, and in that the strip of sheet metal, as it is displaced, is progressively bent around the shaping mandrel on either side of said generatrix by appropriate pressure means which constrain it to follow the contour and dimensions at the point where their action is exerted, and in that the point of action of said pressure means is displaced along the spindle according to any appropriate law for producing a desired variation of section on the shaped part thus obtained. Such shaped parts may be the masts of pleasure-boats, or support poles for the installation of external lighting.

Title: Device in an evaporative cooler
IPC: F28C1/04
Filed: 1978-09-22
Abstract: In an evaporative cooler having a casing, a multilayer type contact body and means for supplying water to selected channels in the contact body, the top edges of the contact body are formed to define outwardly widened openings communicating with only selected channels in the body.

Patent ES-8301560-A1 (ES)
Title: Regulated DC power supply
IPC: H02M7/155
Filed: 1981-07-17
Abstract: A regulated DC power supply has a converter having a plurality of switches which, upon proper regulation of their conduction, rectify an AC current. The converter produces a current feedback signal. A reference generator produces a plurality of adjustable reference signals each representative of one value of a load current and produces a predetermined, standby, reference signal representative of a standby load current. One of the adjustable reference signals, the standby reference signal, and the current feedback signal are added to produce a control signal. The control signal is compared to a signal representative of the AC source voltage. Firing signals, used to regulate the conduction of the switches, are produced in response to the existence of a predetermined relationship therebetween. In the event that all of the adjustable reference signals have a value of zero for a predetermined period of time, the firing signals will be inhibited from regulating the conduction of the switches.
