Patent ES-362795-A1 (ES)
Title: Process for the preparation of new plastics materials, and plastics materials produced by said process
Inventor: LEFEBVRE MICHEL
IPC: C08J11/10
Filed: 1969-01-22
Abstract: A poly(aminoacid) is treated with a solution comprising a hydrogen halide in a mixture of water and alcohol at a concentration which effects a depolymerisation such that the reduction of the degree of polymerisation by 50% takes more than a minute and in a quantity sufficient to take all the partially depolymerised polyamide into solution, and the resulting solution is then neutralised with an alkali to form a precipitate. Preferably the solution is allowed to stand for about a day before neutralisation. A softening agent e.g. polyoxyethylene sulphonate or menthol or other phenol may be mixed with the solution or neutralising agent. Precipitation may be effected in the presence of a filler, e.g. rare earth oxides, or in situ on a fabric. In the case of nylon 6 HCl at a concentration exceeding 2 moles/litre may be used. The precipitation product is stated to have ionic sites which cause reticulation giving a cellular product having very different electrostatic properties from the starting polyamide. Uses. The application of the process with neutralisation effected in situ on a fabric is stated to improve opacity, moisture-absorbance and fire-resistance and to modify the dyeing properties. A further treatment with aqueous sodium bicarbonate forms bubbles in the coating and give a simulated leather appearance. Polymer precipitates on a filler may be used for radiation-deflecting or absorbing screens. Specified fabrics are cotton, polyester and nylon. In the case of nylon contact with the solution prior to neutralisation should be brief (less than 10 and 3 seconds for nylons 66 and 6 respectively) and the fabric may first be dipped in water. The solution may be applied by doctor blade, bath or roller.

Patent ES-480763-A1 (ES)
Title: Relocate feature for an electronic typewriter
IPC: B41J21/17
Filed: 1979-05-21
Abstract: On electronic typewriters which have the ability to record into a small working memory those characters, functions and escapements which are keyed at the keyboard, it is many times advantageous to be able to place the carrier and the print point over a character which has been previously typed without using repeated backspaces. Disclosed herein is a feature for an electronic typewriter which permits the operator to easily align the print point with a character on the page by positioning a reference mark on the card holder or print carrier in relation to a previously printed character and then through keyboard control cause the carriage to shift its position such that the print point is then exactly aligned with the character printed. The positioning of the carrier such that the reference mark is in relation to the desired print point is accomplished by a backspace operation and the repositioning or causing of the carrier to assume a position immediately over the subject character is accomplished by keyboard control through the electronics of the typewriter to cause the carrier to shift a predetermined distance.

Title: Combined linearity and side pincushion correction arrangement.
IPC: H01J29/70
Filed: 1980-01-09
Abstract: A linearity inductance (23) and a side pincushion correction inductance (25) are wound on outer leg core portions (21a, 21b) of a single E-shaped core. A magnet (22) biases the linearity inductance core portion (21a) for saturating that portion each horizontal deflection cycle for producing a linearity corrected horizontal deflection current. A high reluctance path for flux mutually linking both the linearity and side pincushion correction windings is provided by the E-shaped core configuration. The portion of the flux generated by the side pincushion correction winding (25) that does flow in the linearity winding core portion (21a) compensates for undesirable vertical rate changes in the magnetic bias of the linearity winding core portion (21a).
