Title: Process and apparatus for manufacturing thick threads from highly polymeric polymethylene terephthalate, and threads when thus manufactured
IPC: D01F6/62
Filed: 1959-10-26
Abstract: Thick threads are made from polymethylene terephthalates, especially polyethylene terephthalate, by extruding the threads into a liquid bath, guiding them therethrough by one or more deflecting members, and thereafter stretching the threads to a few times their original length, the process being effected under conditions such that the threads at their first point of deflection in the liquid bath are at the second order transition temperature. Thick threads are defined as monofilaments of diameter not below 0.2 mm. The threads are preferably guided over a curved surface at the second order transition temperature. As shown, suitable apparatus may comprise an extender 1, measuring pump 2, spinning plate 3, bath 4, and one or more thread-deflecting members 9, 10, 11, the first deflecting member 9 being movably mounted in the direction of the thread travelling thereto and being kept in equilibrium by a member 15 (e.g. a spring) which maintains a constant tension in that portion of the thread which has not yet passed the first deflecting member. By means of the member 15 the apparatus can be so operated that the first deflection point will automatically coincide with the point of the thread having the second order transition temperature. Methods of measuring the temperature of the thread at the first deflection point are described. The threads are withdrawn by rollers 12 and collected on winding roll 14. The collected threads may then be stretched between roller quintets 16, 17 while subjected in chamber 18 to the action of saturated steam at 100 DEG C., pulled under tension by draw-off rollers 19 through chamber 20, heated by steam at 120 DEG C. and wound-up.

Title: A System for Interconnecting the Prismatic Bars of a Moderator Stack of a Nuclear Reactor
IPC: G21C5/04
Filed: 1967-02-08
Abstract: A moderator stack for a nuclear reactor comprises a plurality of columns of blocks of moderator material, e.g. graphite, placed one upon another, the blocks being keyed to blocks in adjacent columns in such a manner that the blocks can move vertically relative to one another and transversely toward and away from one another in a plane normal to the column axes while maintaining the relative relationship between the column axes, the keying being effected by keys making sliding engagement with the walls of keyways in the blocks at spaced zones along the. keyways. The keyways may be disposed in the block side surfaces, and/or at the corners. The keys may have a reduced central part and co-operate by way of their ends with keyways having a constant width, or have a widened central part and cooperate with the keyways by way of this central part. Alternatively, the keys may have a constant width and the keyways a widened or reduced central part. The keys may be either integral with or separate from the blocks. In other variants, the keys are integral with the blocks and form tenons either at the block ends or in the central part of the blocks which cooperate with keyways having a constant width. The keyways may contain filler elements between the tenons.

Title: Improvements in or relating to razor blades
IPC: C23C8/02
Filed: 1967-06-09
Abstract: A process for the production 'of a razor blade comprises applying a coating of a fluorocarbon polymer to a cutting edge thereof and sintering the coating to adhere it to the edge, in which prior to, during, or after the sintering step the blade is heated at a temperature of at least 300 F in a reducing atmosphere containing from 2 x 1014 to 2 x 1015 molecules of oxygen per cubic centimeter. The polymer may be a homo-polymer of tetrafluoroethylene or a co-polymer of tetrafluoroethylene with small amounts e.g. up to 5% by weight, of hexafluoropropylene, especially those having a molecular weight of 5000 or more. The desired concentration of molecular oxygen can be provided by controlled addition of a small amount of molecular oxygen to a reducing gas or a mixture of such gases, such as hydrogen or cracked ammonia and using the mixture obtained at normal atmospheric pressure. Alternatively a gas such as water or carbon dioxide which decomposes at elevated temperature to form an equili- 'brium mixture containing molecular oxygen may be employed. A further method is by the use of the air at a reduced pressure.

Patent ES-426422-A1 (ES)
Title: Copy sheet and method of printing the same
IPC: B41M5/382
Filed: 1974-05-17
Abstract: A copy sheet that is capable of being printed by a reaction which requires the presence of three components. One of these components is carried by a printing master and another of these components is supplied to the copy sheet immediately prior to the printing operation. The third component is carried by the copy sheet in the form of a layer provided on one side of a carrier sheet forming part of the copy sheet. The printing master is placed on a rotating drum and the layer on the carrier sheet is moistened to supply the still missing component and is thereafter urged into contact with the printing master by means of a counter-pressure roller. If, in making a series of prints on a number of copy sheets, one copy sheet in the sequence should fail to be conveyed to the printing location, the rotating printing master will contact the counter-pressure roller and apply thereto the component carried thereby. This gives rise to the problem that the back side of the next copy sheet will be printed by the counter-pressure roller since this side is moistened and also normally includes at least a small amount of the third component required for the reaction. This problem is eliminated by providing a layer on the back side of the copy sheet which is free of the third component.
