Abstract: Alkali metal polyphosphate complexes of alpha -6-deoxy-5-hydroxytetracycline are prepared which have the formula (C22H24N2O8)z . (MePO3)x . (HPO3 )y in which Me is sodium or potassium, z = 1 to 5, x = 1 to 5, y = 1 to 5, x + y </= 6 and z </= y.

The remaining free acid groups of the metaphosphoric acid are then neutralised with a methanolic or ethanolic solution of sodium hydroxide or potassium hydroxide in the stoichiometric quantity. The complex formed in this process is then precipitated by addition of a non-solvent which is inert to the reaction. Preferred compounds are the ethanol/water solvate of the complex of the formula C22H24N2O8 . NaPO3 . (HPO3)5 and C22H24N2O8 . (NaPO3)2 . (HPO3)4.

Patent ES-455335-A1 (ES)
Title: Shared direct memory access controller
IPC: G06F13/28
Filed: 1977-01-25
Abstract: A microprocessor system includes a microprocessor, a memory, and one or more direct memory access controllers, all connected to a common system bus which includes a system address bus and a system data bus. At least one of the direct memory access controllers is shared by a plurality of subsystem device controllers which may control peripheral devices having diverse characteristics. The microprocessor is limited in its instruction repertoire and may control peripheral devices only by means of an input and an output instruction. The shared direct memory access controller includes no circuitry which is specifically for controlling only a single type of peripheral device, the device dependent logic being located in subsystem device controllers. Data transfers may take place directly between the memory and, through the shared direct memory access controller, any selected one of the peripheral devices. In order to set up the actual data transfer, the microprocessor executes an Input instruction which addresses the status register in a selected subsystem device controller and returns this status to the microprocessor. Next, two Output instructions are executed to load a memory starting address into an address pointer counter in the shared direct memory access controller. Finally, an Output instruction is executed to address a control register in the selected subsystem device controller to load it with a command. After this last operation the actual data transfer takes place on a byte basis through the shared direct memory access controller between the memory and the selected subsystem device controller. The shared direct memory access controller includes an interrupt priority encoder and circuits responsive to an interrupt that is granted priority for placing the status and address of the interrupting subsystem device controller on the system bus. Circuits are included in the shared direct memory access controller for "handshaking" between it and the memory, and between it and the subsystem device controllers.
Patent ES-460949-A1 (ES)
Title: Spot adhesive welding using high power local induction heating - esp. for car trim assembly near heat sensitive or delicate parts
IPC: F16B11/00
Filed: 1977-07-22
Abstract: Covers or linings are spot welded to support structures by rapid induction heating of metallic components or adhesive fillers to fuse or cure the adhesive. Heating of the constituent pieces is promoted by Joule effects from strong Foucault current generation and/or by magnetic hysteressi effects. Used esp. to secure vehicle door linings to door frames or panels by spot bonding at intervals along the lining border using epoxy-resin-based adhesives requiring heating to 100-300 degrees C. Contact or pressure across the assembly is not essential, though opt. desirabl where pressure can be tolerated. Rapid, local heating possible (2-6s) to avoid damage to other heat sensitive material which may be nearby. The open sided heating device is suitable for rapid loading/unloading or assembly line operations.
Patent ES-461043-A1 (ES)
Title: Steering control valve for power booster steering mechanisms
IPC: B62D5/083
Filed: 1977-07-27
Abstract: An otherwise conventional multi-way booster steering control rotary valve plug is provided with needle bearings at both ends of the grooved valve core, i.e., the rotary valve plug, in order to maintain it exactly centered radially within the coacting grooved valve sleeve i.e., a worm shaft in the present instant. This has been found to obviate heavy friction due to buildup of pressure on one side of the valve plug causing eccentricity within the valve worm shaft, such eccentricity causing these components to contact at the opposite side. The arrangement maintains radial clearance within very small limits to preclude significant oil leakage between the components and permits smooth rotary operation.
Patent ES-462400-A1 (ES)
Title: Molded glove and form therefor having textured wrist portion for the elimination of cuff roll-down
IPC: B29C41/40

In accordance with this invention, a plurality of circumferential channels are defined on the wrist portion at the end remote from the hand portion, the circumferential channels crossing the longitudinal channels. The thickness of the glove along the longitudinal and circumferential channels is increased over the thickness of the glove in areas adjacent to the channels. The glove exhibits improved resistance to rolling down of the cuff while being worn, when compared with conventional gloves having longitudinal flutes or channels, gloves having beaded cuffs, and the like.
Patent ES-469507-A1 (ES)
Title: Roof or wall covering
IPC: F24S10/70
Filed: 1978-05-05
Abstract: The roof or wall covering comprises individual hollow profile panels (15a-15d), in particular of plastic, which permit a lateral groove-and-tongue connection and are concavely drawn in, transversely to their longitudinal direction, on the upper and lower surfaces. In the interior of the hollow profile panels (15a-15d), there are located profile chambers (17, 18, 19) which pass through in the longitudinal direction and permit a carrier fluid to be received, either directly or in drawn-in lines (20, 21, 22), provided that they are used in conjunction with solar-energy systems. Connecting pieces, which can be pushed into the profile chambers (17, 18, 19), permit the connection of a plurality of hollow profile panels (15a-15d) in the longitudinal direction. In order to simplify mounting, there are provided fastening elements which engage in the grooves of the groove-and-tongue connection and exhibit base plates, which are fastened on the substructure and are used, at the same time, for the sliding support of sliding surfaces on the edges of the hollow profile panels (15a-15d). When used in solar-energy systems, air can be sucked through the profile chambers (17-19) of the hollow profile panels (15a-15d) and heated and fed to a heat pump. Furthermore, the profile chambers (17-19) can form a closed system which channels a carrier liquid.

The resultant shaped articles are useful, e.g., catalysts or catalyst carriers/supports.
Patent ES-472894-A1 (ES)
Title: Continuous business forms assemblies
IPC: B41L1/26
Filed: 1978-08-01
Abstract: The form arrangement consists of multi-layer sets of forms, connected one behind the other, which can be advanced through the printer of an office machine. Two outer, endless layers (11, 12) are separably connected to each other at the longitudinal edges and have tractor feed perforations (13) and, for separation, transverse lines (36) of weakness. In between the latter lie intermediate layers (21, 22, 23, 24, 28) which are connected to form individual sections. The sections are connected, only along one longitudinal side of the form arrangement, to each other and to only one of the outer layers, in a separable manner. The printed sets of forms are each completely separated at the transverse lines of weakness. With this arrangement, however, only the section and one outer layer (11) of the last printed set of forms can be separated easily, whereas the other outer layer (12) can be left as a drive web for initiating the advance of the subsequent sets of forms to be printed. As a result, the whole set of forms is not wasted for this purpose.
