Patent ES-462123-A1 (ES)
Title: Device for dividing predetermined number of pieces overlaped with each other like scales into groups
IPC: B65H33/12
Filed: 1977-09-05
Abstract: A horizontal belt conveyor (2) is used to split a flow of flat and overlapping objects (5) into individual groups. Two heavy cables or chains (13) are suspended above the conveyor belt by means of pneumatic cylinders (9, 15). The brake cables (13) form an arc such that the lowest point is above the end of the conveyor (2). In order to produce a gap between the overlapping objects (5), the brake cables (13) are lowered so that, starting from the exit end (3), the overlapping objects are clamped against fixed guide rails. Thus by slightly increasing the amount of overlap, the flow can be separated into groups without stopping the conveyor belt (2).
Patent ES-469165-A1 (ES)
Title: Detachable connections particularly for furniture
IPC: F16B12/20
Filed: 1978-04-26
Abstract: The tongue plate comprises two diametrically opposed tongue parts (4, 5), each of which has a hook (40, 50) which engages into the hook mouth (53, 43) of the other hook (50, 40) when the tongue plate is assembled. The assembled tongue plate then forms a two-sided figure which is delimited by identical arcs of a circle. The diagonal, acting as the separating plane, of said two-sided figure is aligned with opposite guiding surfaces (near the ends of the arrows 4, 5) and with inner surfaces, acting against each other, of the hooks (40, 50). The tongue parts (4, 5) can be inserted into grooves (1'', 2'') which are in the form of portions of a circle and belong to structural parts (1, 2), the surfaces (1', 2') of the structural parts (1, 2) then being aligned with the said diagonal of the assembled tongue plate. The structural parts (1, 2) can be connected when the hooks (40, 50) of the tongue parts (4, 5) are pushed one into the other, for which purpose the surfaces (1', 2') of the structural parts are laid one upon the other and the structural parts (1, 2) are displaced along these surfaces (1', 2') in the direction of the hooks (40, 50). The connection is released conversely.

Patent ES-8104337-A1 (ES)
Title: Process and mixture for the preparation of a polyisocyanurate foam.
IPC: C08G18/02
Filed: 1980-07-04
Abstract: The process involves adding a blowing agent containing a trimerisation catalyst to a prepolymer formed from a polyol and an isocyanate. The polyol and the isocyanate are mixed with one another in the prepolymer in a molar ratio of 1:3 or more. In addition, it is appropriate to use a catalyst which is soluble in the blowing agent and to provide the prepolymer with a foam stabiliser, a flameproofing agent and/or similar additives. This allows a PIR foam which can easily be adapted to the particular application to be produced economically without complex machinery virtually anywhere. This is because the prepolymer formed from the polyol and isocyanate and stored in a storage container is foamed in a static or dynamic mixing unit merely by admixing a modifiable amount of a blowing agent which contains the trimerisation catalyst and is likewise premixed. Thus, the processor needs no metering equipment instead, the containers containing the prepolymer and the blowing agent with catalyst can be connected directly to a spray gun. The supply of the blowing agent in the mixing unit produces a foam which is finished in volume terms and cures in a time of, for example, from 5 to 20 minutes. Its initiation and rise time can be modified by means of the trimerisation catalyst, and an inexpensive PIR foam having a high thermal insulation capacity and thus a low density of, for example, 25 kg/m<3> can be produced during the foaming by merely adding an appropriately large amount of blowing agent to the prepolymer. By contrast, in the production of a heavy foam as a construction material which can be used to fix components, the amount of blowing agent to be added is reduced, for example using a spray gun, so that the density is increased up to 60 kg/m<3>.

Title: Solvent refining of coal using octahydrophenanthrene-enriched solvent and coal minerals recycle.
IPC: C10G45/44
Filed: 1981-02-04
Abstract: Ash-containing raw coal is converted to a liquid fuel product by contacting the coal with hydrogen and an OHP-enriched solvent containing OHP and THP in a ratio of OHP/THP greater than 0.4, wherein the OHP is present in an amount of at least 5 weight percent of the solvent, to produce a liquid stream and a coal minerals stream, and recycling at least a portion of the coal minerals stream. A portion of the liquid stream (64) is catalytically hydrogenated (68), preferably with a tungsten-containing catalyst, to increase the ratio of OHP/THP to a value greater than 0.4 or preferably greater than l. The OHP-enriched liquid stream solvent is passed as solvent to a mixing zone (11) where it is admixed with raw coal (10) and recycled coal minerals (38), admixed with hydrogen (58) and passed to a preheater (20) and dissolver (24). The use of the OHP-enriched solvent improves coal solvation and liquid distillate production, while the recycle of coal minerals assists in maintaining a high OHP level in the circulated process solvent. By increasing the OHP/THP ratio to a value greater than 1, the amount of hydrogen consumed in the process can be significantly reduced.

Title: A process for the in-solvent, in-situ generation of N-substituted-2-haloacetanilides.
IPC: C07D309/24
Filed: 1981-03-18

Patent ES-8300053-A1 (ES)
Title: Control arrangement for an antiskid hydraulic braking system of a vehicle
IPC: B60T8/48
Filed: 1981-10-27
Abstract: A control arrangement for use in a hydraulic braking system equipped with an antiskid control device and an auxiliary energy source and including a master cylinder device which is operated in dependence on the travel of a brake pedal, includes normally open separating valves in braking conduits to the wheel brake actuating cylinders, which close during antiskid control operation, provided that auxiliary energy is available. An auxiliary supply conduit supplies the auxiliary energy to the wheel brake actuating cylinders so that the latter can be operated in a dynamic manner. A normally closed return valve is interposed in the return conduit from the respective wheel brake actuating cylinders and can be opened, either directly or indirectly, by the auxiliary energy during the antiskid control operation, so that the pressure from the wheel brake operating cylinder to be controlled can be relieved to the low-pressure supply reservoir while rendering static operation of the wheel brake actuating cylinders possible in its normal closed position assumed when no antiskid control action is needed. The pressure of the auxiliary energy hydraulic fluid can be generated by a hydraulic pump which is operated only during the antiskid control action, or the auxiliary energy supply system can be operated on a continuous basis, in which case the auxiliary hydraulic fluid is supplied to the hydraulic braking circuit only when the need for an antiskid control action arises.
