Patent ES-8103153-A1 (ES)
Title: Apparatus and method for solar coal gasification
IPC: F24S20/20
Filed: 1980-04-12
Abstract: Apparatus for using focused solar radiation to gasify coal and other carbonaceous materials. Incident solar radiation is focused from an array of heliostats onto a tower-mounted secondary mirror which redirects the focused solar radiation down through a window onto the surface of a vertically-moving bed of coal, or a fluidized bed of coal, contained within a gasification reactor. The reactor is designed to minimize contact between the window and solids in the reactor. Steam introduced into the gasification reactor reacts with the heated coal to produce gas consisting mainly of carbon monoxide and hydrogen, commonly called "synthesis gas", which can be converted to methane, methanol, gasoline, and other useful products. One of the novel features of the invention is the generation of process steam at the rear surface of the secondary mirror.

Patent ES-8402474-A1 (ES)
Title: Rotor with a laminated segmented rim and mounted poles for electric machines.
IPC: H02K1/30
Filed: 1983-03-25
Abstract: A larger number of keys (L) are formed in the outer cylindrical surface of a rotor rim than is strictly necessary for fixing pole pieces (P) thereto. The keys are regularly spaced around the rim. This arrangement makes it possible to avoid having adjacent rim segments offset to each other by an angle which is equal to the pole pitch or at best to the half pole pitch as has previously been the case. The overlap between segments may now be at the pitch of the fixing keys. This can be used to increase the overlap factor, thereby increasing the mechanical strength of the rim against centrifugal forces.

Title: Laundry softening detergent
IPC: C11D3/12
Filed: 1983-04-07
Abstract: A heavy duty laundering and textile softening detergent composition, in particulate form, useful for automatic machine washing of laundry in water, especially hot water, and readily dispensable from a charging compartment of an automatic washing machine (by action of water being fed through such compartment) includes a synthetic organic detergent, a builder for such detergent and a laundry softening proportion of bentonite, with which there is present a dispensing assisting proportion of a siliconate or similarly functioning derivative of such siliconate. In addition to tending to inhibit firm adherence to the charging compartment walls of the bentonite, which is advantageously in separately agglomerated bead form, and promoting release thereof from such walls, the siliconate also aids in controlling the foaming activity of the built synthetic organic detergent and in strengthening the bentonite agglomerates. It also assists in stabilizing perfumes, dyes and bleaches when such are present in the detergent compositions when it is employed in coatings for particles containing such components.

Patent ES-8405229-A1 (ES)
Title: Improvements relating to video data transmission.
IPC: H04N7/32
Filed: 1983-07-22
Abstract: A conditional replenishment video data transmission system involves the transmission of digital values representing the brightness changes at picture elements of a raster scanned image since the previous frame. Since nothing is transmitted for those picture elements without a significant brightness change, the amount of data to be transmitted will depend on the extent of movement in the image, and buffer stores are provided to allow the use of a constant transmission rate. If the extent of movement in the image is very high the buffer store at the receiver will tend to fill up and might overflow. In order to avoid this occurring, reduction of the amount of data to be transmitted by element subsampling has been proposed in which in a cluster of changing elements data relating to only some, for example alternate ones, of the elements are transmitted, and interpolation is used at the receiver to calculate the brightness change data for the omitted elements. The blurring of vertical edges in the image resulting from the interpolation is avoided by suspending sub-sampling where vertical edges are detected in the image. When in the sub-sampling mode, in order to avoid having to mark those normally omitted elements for which data are transmitted the receiver is arranged to detect the presence of a vertical edge and respond by treating the data as if they relate to all elements in the vicinity of the edge and not just the sub-sampled ones. Transmission error can result in the receiver being incorrect in the detection of edges, and to avoid this the number of quantizing levels during sub-sampling is reduced from 8 to 4, using one set of 4 codes for the normally present elements and the other set of 4 codes for the normally omitted elements. Since a vertical edge will usually appear in more than one line, the receiver may be arranged to check the previous line for a vertical edge and anticipate the inclusion of normally omitted elements if such an edge has occurred.
