Patent ES-420407-A1 (ES)
Title: Starter motors
IPC: F02N11/00
Filed: 1973-11-09
Abstract: A starter motor for an internal combustion engine comprising an electric motor capable of rotating a shaft. A pinion gear wheel carried by the shaft, and rotatable therewith, the gear wheel also being movable axially relative to the shaft. An electromagnet including an armature which is coupled to the pinion gear wheel so that the two can move axially relative to the shaft. The electromagnet also includes a plurality of electromagnet poles which are equi-angularly spaced around the shaft in a plane at right angles to the axis of the shaft, and which are spaced apart by an amount such that the armature can enter between the poles. In the rest position of the armature there is a clearance between the poles and the armature in the direction of movement of the armature. The shaping of each pole is such that the surface of the pole presented to the armature includes regions which are spaced from the armature by different distances in the direction of movement of the armature, and which are equally spaced from the shaft in a radial direction. The electromagnet further includes a member which magnetically interconnects the poles and a winding associated with the poles so that when energised there is a flow of magnetic flux between the poles and the armature, within the armature at right angles to the direction of movement thereof, and between the poles by way of said member, such that the armature is attracted to the poles. The arrangement of said regions of the pole surfaces is chosen to achieve a predetermined attraction between the poles and the armature during the movement of the armature towards the poles.

Patent ES-486529-A1 (ES)
Title: Continuous process and apparatus for adsorbent bleaching of triglyceride oils
IPC: C11B3/10
Filed: 1979-12-03
Abstract: Triglyceride oils are bleached rapidly and efficiently in a continuous system wherein a stream of the oil is preheated to bleaching temperature and is introduced into a mixing zone in such manner as to provide a swirling motion, bleaching adsorbent containing moisture is added to the surface of the swirling hot oil and water vapor or steam derived from the moisture in the adsorbent forms a protective atmosphere above the surface of the oil to protect it from oxidation. The oil-adsorbent mixture is pumped continuously from the mixer to a bleaching zone consisting of one or more static mixers, which may be unobstructed pipe sections, under flow conditions providing an average residence time of approximately one minute. The flow regime in the bleaching zone may be laminar or turbulent. Optionally, the oil-adsorbent mixture may flow continuously from the mixing zone to a vacuum dryer where it is deaerated and dried to optimum moisture content for bleaching prior to being pumped to the bleaching zone. Total time through the system may be in the order of less than three minutes. The advantages include simplicity of the operation, savings in time and ease of changing feedstocks.

Patent ES-8103312-A1 (ES)
Title: Synchronized transmission
IPC: B60K23/08
Filed: 1980-04-02
Abstract: A tractor transmission is synchronized between four different speeds in each of two different high and low ranges and a reverse range. A top shaft coupled to be driven by the tractor engine has four different gears which are concentrically and rotatably spaced along the length thereof in constant mesh with a different one of a second group of four gears formed on the outer surface of a counter shaft. The counter shaft is selectively coupled to the top shaft by either of two pairs of synchronizers concentrically mounted on the top shaft between different pairs of the first four gears. High and low ranges are respectively provided by a first splined collar capable of coupling the counter shaft directly to a differential drive shaft and a second splined collar capable of coupling the differential drive shaft to the fourth gear disposed about the top shaft via a low range driven gear. Upon loss of hydraulic fluid pressure, a planetary gear arrangement coupled between the top shaft and the tractor engine is automatically returned from a direct drive condition to an underdrive condition by mechanical springs within two different clutches associated therewith. Similar safety features are provided in connection with the front wheel drive portion of the transmission.

Title: Process for making products based on calcium silicates and/or calcium aluminates.
IPC: C04B14/04
Filed: 1980-09-23
Abstract: A process for manufacturing calcium silicate and/or aluminate based products, such as Portland cement or aluminous cements. The raw material subjected to a first heating step in which it is heated in a preheater-decarbonator and/or a rotating kiln to a temperature less than that at which impurities, such as alkalines, chlorine and sulfur, are volatized. The heated raw material is then subjected to a second heating step in the presence of a reducing gas, preferably in a plasma furnace, the raw material being heated to a temperature higher than the temperature at which the impurities are volatilized, as for example above 1950 DEG C., and more than 80% of the material is in fusion, whereupon the material is cooled to produce the clinkers of improved quality and/or with lower energy consumption. An important feature of the invention is the utilization of the gases generated during the second heating step and during cooling to implement heating of the raw material. It is equally important, however, that the gases generated during the second heating step are not utilized to heat the raw materials unless such gases are first purified.
