Title: Improvements in or relating to the manufacture of high molecular weight synthetic linear polyamides
IPC: C08G69/04
Filed: 1967-11-08
Abstract: Pigmented high M.W. linear polyamides are prepared by condensing one or more monomers selected from: a diammonium salt of a diamine NH 2 -X-NH 2 with a dibasic acid HOOC-YCOOH or an amino acid NH 2 -Z-COOH. X, Y and Z denote methylene chains, X and Y together contain at least 6 methylene groups and Z at least 3. The methylene chains may be interrupted by 0, 1 or 2 meta or para-phenylene groups and may also bear alkyl or aryl substituents and may optionally contain -O- links, providing the groups -O-O-, -O-CH 2 -N- and -O-CH 2 -CH 2 -CO- are absent. An aq. soln. of the said monomer or monomers is pumped through an elongated reaction zone heated to polymerization temperatures in which the reaction mass flows in two phases from an initial pressure at the inlet of at least 14 atmospheres to a pressure of not more than 1 atmosphere at the outlet. At a point in the reaction zone at which the temperature of the reaction mass is not more than 5 C. below the temperature of the vessel walls and the pressure is at least 7 atmospheres greater than that at the outlet, a dispersion (preferably aqueous) of pigment, e.g. TiO 2 or carbon black, is introduced into the reaction mixture and polymerization is completed. Examples of suitable polyamide forming monomers are: hexamethylene diamine with adipic acid, sebacic acid, suberic acid, terephthalic acid or isophthalic acid m-xylylene diamine and adipic acid dodecamethylene diamine or nonomethylene diamine with terephthalic acid #-aminocaproic acid and #-aminoundecanoic acid. The resultant polyamines are suitable for the fabrication of films, filaments and ribbons. In a typical example a polyamide of hexamethylene diammonium adipate is pigmented with TiO 2 at a reaction temperature of 290 C. and using an initial pressure of 23 atmospheres. The reaction zone in the form of a steel coil is 273 metres in length.

Title: Electrical winding structures
IPC: H01F27/28
Filed: 1968-03-23
Abstract: A disc coil winding in which each disc coil 19, 20, 22, 23 (Fig. 1) comprises two (or more) insulated conductive strands A, B, forming radially interleaved turns at least one strand in each coil being severed at least once (e.g. at B0/B6, B6/B12) to provide radially separate portions having inner and outer radially spaced ends. The relative positions of two parallel circuits through the coils are transposed from one pancake coil to the next. Transposition of the position of the A and B circuits between coils 20 and 22 may be arranged as in Fig. 1 or Fig. 4 a detailed description of the method of construction and interconnection being given (Figs. 2 and 5, not shown). In a preferred arrangement the A and B conductors are severed alternately in alternate coils to provide radially separate portions and this arrangement may be used in a double interleaved construction as shown diagrammatically in Fig. 7. Four conductive strands LA1, LB1, LC1, LD1 may be used as illustrated in Fig. 9 which shows a single interleaved arrangement in which full transposition of the strands needs four coils. The procedure for winding the coils, and cutting, and interconnecting the conductors to give only one brazed joint per coil is described (Figs. 10- 14, not shown). The methods and constructions involved in providing tappings are also described in detail (Figs. 15-21, not shown). Fig. 26 shows an arrangement having three conductive strands per coil, only two being interleaved at any section of a coil, full transposition of the conductive strands occurring over three coils. A comparable arrangement with different interconnections is also described (Figs. 27 and 28, not shown) as are other threeconductor arrangements (Figs. 31-33, not shown) and two four-conductor arrangements (Figs. 29 and 30 and 34 and 35, not shown).

Patent ES-362184-A1 (ES)
Title: Magnetic copy system
IPC: G06K1/04
Filed: 1969-01-07
Abstract: In the copying of a plurality of recorded tracks from a master record to a copy record, the master and copy records are disposed with their recording surfaces face to face and mutually offset by an odd number of track surfaces. This restores the original direction of playback for each track in the case of to and-fro (boustrophedonic) recording, the copy being a mirror image of the master. As shown, a master record card M and a duplicate card D are inserted through a slot 3 into a housing 1 where they are latched in suitably offset positions. They are then pressed together on depression of a handle 6, and movement of a sliding knob 8 along a slot 1b causes a drum 11 containing permanent magnets (11a Fig. 3a) to roll along a rack (13) across the cards and effect the copying operation.

Title: Laser recording technique using combustible blow-off
IPC: G03C5/56
Filed: 1972-09-28
Abstract: A recording technique using a laser beam for image recording on a film. In the preferred embodiment, the film comprises a transparent substrate coated with heat absorbing particles, dispersed in a self-oxidizing binder. Contrary to the present practice of directing the laser beam on the coating itself, the laser beam is directed through the substrate with its energy focused on the boundary interface between the substrate and coating. This causes the coating to be removed, as by blow-off or explosion, leaving a clear area on the substrate forming a positive image of the recorded material.
