Patent ES-8701808-A1 (ES)
Title: Hydrolysis of alkoxysilanes
IPC: B01J21/16
Filed: 1982-10-06
Abstract: Alkoxysilanes are hydrolyzed with water in the presence of various hydrolysis catalysts. The hydrolysis catalysts include the solid oxides of the Group IIa metals and solid acid catalysts. The solid acid catalysts are used in conjunction with neutralizing agents and optionally with condensation catalysts. Generally, the process for hydrolyzing alkoxysilanes comprises: mixing an alkoxysilane, a stoichiometric excess of water and an effective catalytic amount of hydrolysis catalyst selected from the group consisting of a solid oxide of a Group IIa metal, a solid acid catalyst and mixtures thereof neutralizing the hydrolysis mixture with a sufficient amount of neutralizing agent, for example, magnesium oxide and separating the hydrolysis product from the mixture. When a Group IIa metal oxide hydrolysis catalyst is used, the liquid portion of the hydrolysate is neutral, and no additional neutralizing agent is required in the mixture. By the process of the present invention, the average chain length of silanol-stopped polysiloxanes can be controlled. A stabilized, crystalline tetramethyldisiloxane diol and a crystalline dimethyldisilanol have also been prepared by modified catalytic hydrolysis processes using solid acid catalysts to catalyze the hydrolysis of dimethyldimethoxysilane with water.

Patent ES-8402095-A1 (ES)
Title: Discrete fourier transform circuit.
IPC: G06F17/14
Filed: 1982-11-23
Abstract: In a transmultiplexer, which is an interface between a number of PCM highways and an FDM group, the conversion between PCM and FDM involves first converting the PCM words into their linear form and filtering them, applying them to a circuit which performs a discrete Fourier transform (DFT) on them followed by a second stage of filtering. An efficient implementation of a DFT is described which reduces the number of multiplications required by making use of certain symmetry properties in a DFT matrix. The whole can be used <<backwards>>, as it were to give an inverse Fourier transform as needed for the FDM-PCM conversion.

Patent ES-8501699-A1 (ES)
Title: A method and an arrangement for the manufacture of packing containers.
IPC: B65B31/04
Filed: 1983-09-26
Abstract: The manufacture of non-returnable packages is frequently carried out by the conversion of web-shaped, laminated packing material to a tube, filling of the tube with milk, and sealing and forming the filled packing containers to the desired shape. During the forming, which is done by external forming devices, the contents are used as a mandrel or a holder-up for the forming device, so that the desired shape can be achieved without creasing or other deformations. The above-mentioned forming principle works less well if the packing containers are not completely filled, but have a certain air space or headspace. The proportioning of the contents also becomes uncertain and the desired accuracy of volume cannot always be achieved. These difficulties are overcome by the invention wherein a sealed off part of the packing material tube is pressurized with the help of gas during the forming process, so that the internal back pressure required during the forming is obtained, independently of the quantity of contents. The method also permits an accurate proportioning of the contents either by continuous feed at a controlled flow rate or by discontinuous feeding in portions. The invention also relates to an apparatus for the realization of the method.

Title: Microporous separator for storage batteries and relative process and apparatus for continuous manufacture.
IPC: H01M50/463
Filed: 1984-03-30
Abstract: The separator comprises a plurality of longitudinal channels and ribs. The ribs are hollow and closely spaced apart with center distance less than 12 mm. Both the channels (C1, C2, ...) and most of the ribs (N3, N4,...) have longitudinal hollow projections respectively protruding on the two opposite sides of the separator. The ribs and projections contribute to define the bearing planes or faces of the separator, improve the characteristics thereof of longitudinal and transverse rigidity and assure a constant spacing between the plates when assembled therebetween owing to the increased number of contact points or locations therewith. The distribution of projections on a separator is sufficiently different from that of a plurality of separators intended to be superimposed or stacked to one another, no projection of one of such separators can nest in a cavity of another separator an the extraction of any separator from the pack can be readily carried out. In a continuous production process, the separators are obtained from a strip of material which in case is preheated, then drawn by means of two rollers and finally cut to measure. The strip may be fed from a roll or from a strip forming system, and particularly from a sintering furnace when using thermoplastic powders.

Title: Debounce circuit providing synchronously clocked digital signals.
IPC: H04L25/08
Filed: 1984-10-05
Abstract: An improved debouncer circuit is disclosed for providing debounced, synchronously clocked digital signals from a single-throw switch, as for instance, of the momentary contact type. A signal, variable between two logic levels, is provided by the switch for input to the debouncer circuitry. That input signal is applied as one input to an EXCLUSIVE OR gate, the other input to that gate being fed back from the Q output terminal of an output data latch having complementary Q and Q* output terminals. A signal representing the Q* output terminal of the data latch is connected to the D input of that latch such that a synchronous latch clocking signal appearing at the clock input of the output data latch serves to toggle the states of the Q and Q* output terminals. The signal appearing at either one of the output terminals Q, Q* of the output data latch may be used as the debounced signal provided to other circuitry, depending upon signal polarity needs. The clocking signal which toggles the output data latch is the output of a NAND gate. The inputs to the NAND gate include one phase of a two-phase synchronous clock signal, the output of the EXCLUSIVE OR gate, and the signal from the Q output of a second data latch. The second data latch is clocked by the other phase of the two-phase synchronous clock. The D input of the second data latch is connected to the output of an AND gate, with the inputs to the AND gate being provided by the O* output of the second data latch and by the output of the EXCLUSIVE OR gate.
