Title: Resinous polymer sheet materials having selective, surface decorative effects and methods of making the same.
IPC: B41M3/06
Filed: 1979-02-20
Abstract: Resinous polymer sheet material having surface decorative effects. The material is made by applying to a potentially foamable resinous composition (16) a printing composition layer (18) forming a pattern and then applying to said printing composition layer a resinous polymer wear layer (22) having therein reactive polymerizable and cross-linkable monomeric materials. There is included in areas (20) of the sheet material a polymerization initiator, perferably dicumylperoxide, capable of initiating a polymerization and cross-linking reaction of the monomeric materials, and the surface of the wear layer is heated in order to develop the foam, preferably also mechanically embossed, and to bring about such reaction at the areas of the polymerization initiator. The melt viscosity of the wear layer at said areas is thereby increased so that said areas will have a different appearance than the other area of said wear layer.

Patent ES-480219-A1 (ES)
Title: Electrophotographic copying machine including an automatic document feeder.
IPC: G03G15/23
Filed: 1979-05-04
Abstract: An electrophotographic copier includes an automatic document feeder (ADF) 16 operable to feed sheets in turn from a feed stack. In order to produce duplex copies from single sides of the original documents, two copying runs are performed. In the first run, the ADF is controlled by logic circuitry 140 and input circuits 165, 146 to pass odd numbered documents from the feed stack to a receiving stack directly. Even numbered documents are copied. At the end of the run, when all sheets have passed through ADF, the receiving stack is re-positioned to form the feed stack, and a stack of produced copies is placed into the copy feed bin. In the second run, copies of the even numbered documents are produced on the back of the copy papers. A collator receives the copies produced by both runs. During the first run, the collator 20 is controlled by logic 142 to stack the sheets such that no re-ordering is necessary when they are transferred to the copy feed bin.
Patent ES-8203230-A1 (ES)
Title: Solar distillation apparatus
IPC: F24S23/30
Filed: 1979-06-13
Abstract: Solar distillation apparatus in which a substantial part of the heat of condensation of the condensing liquid is recovered. A conduit (14) having an inclined smooth lower surface (54) is disposed below a lens system (12) and above a container (16) for the liquid to be distilled (e.g. salt water) and on which the evaporated liquid condenses and releases its heat of condensation. A fluid is circulated through the conduit in a heat exchanging relationship with the lower surface thereof, the fluid absorbing a substantial part of the released heat of condensation. The condensed liquid flows along the bottom of the inclined lower surface (54) and is discharged from the lower end (56) thereof and collected. The conduit in the preferred embodiments is flat and transparent and the spacing between the upper and lower walls of the conduit is elected so that only a small part of the solar energy is absorbed in the conduit while the fluid in the conduit recovers a substantial part of the released heat of condensation. Preferably, more fluid is circulated in the conduit means than the quantity of liquid evaporated from the distillation compartments and condensed on the conduit means in order to carry away the released heat of condensation while maintaining the temperature of the fluid below that of the condensing liquid vapor.

Title: Multi-purpose vehicle
IPC: B60K17/08
Filed: 1979-08-31
Abstract: A multi-purpose four-wheel drive vehicle having four-wheel steering. The vehicle according to the present invention incorporates a number of features, some of which are individually known in the prior art but which, when combined in a single vehicle, constitute a vehicle having several advantages over conventional vehicles presently employed for various uses. The applicant's multi-purpose vehicle is of light-weight construction, is relatively inexpensive to manufacture in comparison with vehicles presently employed for the same jobs as those accomplished by the present vehicle, and has substantially less initial and operating costs. The applicant's vehicle incorporates a relatively high ground clearance which is achieved by employing four vertical axles and wheels situated at the four corners of a main frame body of the vehicle. The vertical axles are situated in respective spaced-apart leg post members, each leg post member being rigidly interconnected by two spaced-apart longitudinally extending frame members and two spaced-apart transversely extending frame members. At least three of the frame members are of torsionally resilient construction. When a weight is suspended mid-point between the front and rear wheels of the vehicle, this weight may be transferred by the vehicle without traction loss due to the increased load in that true traction is increased as the load increases.

Title: Process for the recovery of carboxylic acids from mixtures containing glycol esters derived from these acids.
IPC: C07C51/44
Filed: 1980-09-30
Abstract: A process for the recovery of carboxylic acids from mixtures containing glycol esters derived from these acids. The process comprises reacting these mixtures at boiling with water to form carboxylic acid and entraining the carboxylic acid formed by means of the water by azeotropic distillation, so as to separate off a mixture of carboxylic acid and water. This mixture is subjected to extractive distillation by means of an organic solvent which is insoluble in water and in which water is insoluble. A mixture of water and organic solvent is thereby separated from a solution of carboxylic acid in the organic solvent.
