Title: Control of thermal convection in a float glass forming chamber
IPC: C03B18/22
Filed: 1975-04-24
Abstract: Thermal convection currents in the headspace above a body of glass being formed into a continuous sheet of glass while supported on molten metal are controlled to prevent the development of surface distortion patterns in the upper surface of the glass being formed. This is accomplished by establishing a series of small convection cells at least adjacent the upper surface of the glass so that the characteristic convective cooling rate for the glass in the forming chamber is substantially diminished, particularly near the inlet end of the forming chamber.

Patent ES-468073-A1 (ES)
Title: Knitting-machine patterning system
IPC: D04B15/76
Filed: 1978-03-20
Abstract: A cam carriage, provided with a jack-filled pattern wheel followed by a knitting cam system, travels along a needle bed of a flat-bed knitting machine. Those pattern-wheel jacks which are selected for operation by a jacquard mechanism cause selected needles to be transversely shifted away from the knitting cam system. The pattern wheel has a first and a second circumferential succession of jacks, and two jacks per interneedle interval of the pattern-wheel circumference. The needle-controlling portions of the jacks of the first succession are located at different heights from those of the second succession. Some groups of needles have jack-engaged members located at the height of the needle-controlling portions of the first jacks. The other groups of needles have jack-engaged members located at the height of the needle-controlling portions of the second jacks. As the cam carriage performs a stroke, and the pattern wheel performs a first rotation, the needles which the pattern wheel passes are controlled by the first circumferential succession of jacks. As the stroke continues, and the pattern wheel performs a second rotation, the needles which the pattern wheel passes during the second rotation are controlled by the second circumferential succession of jacks. Thus, a base pattern can have a width corresponding to twice the pattern-wheel circumference. The correlation between needle groups and the two circumferential successions of jacks is selectable, for implementing complex patterning effects.

Patent ES-485894-A1 (ES)
Title: Clock pulse generating circuit.
IPC: G06F1/04
Filed: 1979-11-13
Abstract: In a microprogrammed processor consisting of several circuitized chips, which are to be synchronously operated, each chip is provided with its own local clock generator or T-ring for deriving therefrom timing signals required during the subphases of micro instruction execution. A master clock connected to all of the T-rings by lines of equal length forces the individual T-rings to operate synchronously and keeps them operating in such a manner. In addition, reset circuitry is provided for forcing all of the T-rings to their first timing interval for initial synchronization thereof or, at an appropriate time, when a micro instruction requiring less than the maximum number of available T-ring timing signals is executed. The timing signals which are locally produced are subject to little delay on their way to the various local switching points. Thus, the entire system can be operated at a higher oscillator or master clock frequency to take advantage of the enhanced processing and transfer speeds of modern, highly integrated circuit chips.

Patent ES-8403652-A1 (ES)
Title: Spectral shift controlled nuclear reactor.
IPC: G21C7/32
Filed: 1981-12-14
Abstract: A spectral shift pressurized water reactor comprising apparatus (38) for inserting and withdrawing water displacer elements (40, 82) having differing neutron absorbing capabilities for selectively changing the watermoderator volume in the core (34) thereby changing the reactivity of the core. The displacer elements (40, 82) comprise substantially hollow cylindrical low neutron absorbing rods (40) and substantially hollow cylindrical- thick walled stainless rods (82). Since the stainless steel displacer rods have greater neutron absorbing capability, they can effect greater reactivity change per rod. However, by arranging fewer stainless steel displacer rods (82) in a cluster, the reactivity worth of the stainless steel displacer rod cluster can be less than a low neutron absorbing displacer rod cluster.

Title: A tissue adhesive and a method of producing the same
IPC: A61K31/70
Filed: 1982-07-27
Abstract: A tissue adhesive based on human or animal proteins contains factor XIII, fibrinogen and an antibiotic. In order to achieve a high straining capacity of the adherences and a retarded antimicrobial efficacy, the ratio of factor XIII to fibrinogen, expressed in units of factor XIII per gram of fibrinogen, amounts to at least 500.

The antibiotic is added either before deepfreezing or lyophilization of the resulting preparation, or after thawing or reconstitution of the same.
