Patent ES-348598-A1 (ES)
Title: Sheet products made from thermoplastic filaments
IPC: D04H3/16
Filed: 1967-12-23
Abstract: A sheet-like product is made by depositing bundles of drawn continuous thermoplastic synthetic filaments on a moving support to form a web of randomly intersecting bundles of filaments, and subjecting the web to a superatmospheric pressure whilst the web is held at a temperature below the melting point of the filaments and above the second order transition temperature of the filaments. The temperature may be 3-50 C. below the melting point of the filaments. The pressure may be 1-180 kg./ sq. cm. and may be applied by nip rolls and/or by a heated roll over which an endless belt passes. Liner belts which may be embossed or woven may be passed between the endless belt and the filaments and between the filaments and the heated roll. The filament feeding device and the conveyer belt receiving the filaments may be reciprocated transversely to the direction of movement of the belt. There may be 5-50 filaments in the bundles. The filaments may be made of polyamides and polyolefines, especially polypropylene, polyethylene and nylon 6. The sheet-like product may be smooth and largely non-fibrous, porous or fibrous. The latter may be heat-sealed on one or both sides.

Title: Wire strip and wrap bit
IPC: H01R43/033
Filed: 1970-05-08
Abstract: A wire-wrapping bit cuts and strips a wire end and wraps a terminal in one operation using "free" ends of insulated wire (that is, not intended to be drawn up tight). The cutting elements are removed, and an easy-feed wire hold guide and length gauge are provided, whereby wire may be fed through the guide up to a striker flange on the shank of the bit, for determining the skinner length and the wire held against withdrawal by being trapped in the skinner plate. A collar surrounding the feed guide assists the feed and permits wire to be fed at 45 DEG to the bit and prevents "snatch." An expanding bit shank, and a feed channel extending its length, both assist in ejection of the insulation after the wrapping operation.

Patent ES-444380-A1 (ES)
Title: Novel anthracycline glycosides and methods of preparing the same
IPC: A61K31/7028
Filed: 1976-01-16
Abstract: Metallic derivatives of anthracycline glycosides such as doxorubicin and daunorubicin are prepared by admixing divalent or trivalent metal cations, preferably Fe(III), with the glycoside and adjusting pH to promote chelation of the metal by bidentate ligands of the glycoside. The derivatives are isolated in essentially monomeric form, and preferably lyophilized for later reconstitution immediately before use in the treatment of transplanted tumors in mice. As compared with the parent glycosides, the derivatives exhibit greatly diminished cardiotoxicity and less general, hematological and digestive toxicity as well. At the same time, the antineoplastic efficacy of the derivatives in transplanted mouse tumor test systems appears to be approximately equivalent to that of the parent glycoside on a mg. to mg. basis. As a result, the therapeutic index of the derivative is greatly elevated over that of the parent, since the derivative may be safely administered in greater quantities.

Patent ES-471406-A1 (ES)
Title: Request forwarding system
IPC: G06F13/28
Filed: 1978-07-04
Abstract: Storage access requests are forwarded from plural input/output channels to shared main storage. An address word in each request designates the identity of the source channel (CHID) and "destination" address (of a doubleword space in storage relative to which one, two or four "data" words shall be transferred). EOT tag signal provides demarcation of requests and also uniquely identifies "1-wide" input (Store) requests. Quadword (QW) tag, presented with "4-wide" requests, enables the storage access system to use a single address in the request to locate two contiguous doubleword spaces in storage. Data tags (D1, D2), presented on a selective basis enable the access system to selectively steer (reorder the positions of) data words in an input request relative to word halves of the addressed space. Consequently the data repositioning function associated with Read Backward operations does not require reordering of data words in the channel buffers (saving handling time and expense of "steering" circuits in the individual channels). In association with a "1-wide" input request a single data tag, D1 or D2, is used to steer the single data word of the request into either half of the addressed space on a selective basis.
