Abstract: 1,246,067. Pulse shaping circuits. BENDIX CORP. 29 Oct., 1969 [26 Nov., 1968], No. 52903/69. Heading H3T. An electrical network for squaring an input voltage signal having repetitive peak voltage valves occurring at the pulse repetition frequency of a reference squarewave, has a signal line 10 shunted to a reference potential line by two paths each including the source to drain path of a field effect transistor switch 16, 20, of opposite conductivity type to that in the other path, in series with a respective capacitor 18, 22 and an energizing means 24; 26, 28, 30, including a reference signal line 31,33 energized by a reference square wave signal synchronized with the input voltage signal, alternately opens and closes switches 16, 20 and closes and opens switches 20, 16. The squarewave reference input at 31 is synchronized with the distorted squarewave signal input 12 so that positive going reference voltage on line 33 turn on diode 28 and field effect transistor 20 which saturates and negative going reference voltage on line 33 turn on diode 24 and saturate FET 16 so that the transistors 16, 20 alternately conduct. The diodes 24, 28 protect the transistors against the reverse voltages applied alternately to their gates. The capacitors 18, 22 charge, when their associated transistor 16, 20 conducts, to voltages which represent the negative and positive going parts of the input square wave so that a square wave output is obtained at 14. Resistor 32 and capacitor 34 filter any h.f. noise from the reference squarewave. The squaring network may be used to shape a train of amplitude modulated waves generated by a gyro in response to the altitude of an aircraft in an automatic pilot system. After the train is shaped it may be applied to a correcting mechanism to maintain the aircraft at a desired altitude.

Two plastics films may be laminated, optionally between surface sheets of paper, non-woven fabric or plastics, or one plastics film may be laminated between such surface sheets using adhesive. The laterally oriented plastics film may be a network produced by slitting, perforating or embossing a continuous film before stretching, or a film which has been fibrillated after stretching, and may also be longitudinally oriented. Lateral and longitudinal orientation may be carried out by tentering and by rollers respectively; the tentering device may also maintain the laterally oriented film under tension for laminating. The following specific laminated constructions are disclosed: (1) A film is slit laterally and stretched laterally before feeding between surface sheets. The slits may be a pattern of staggered rows or a row of long slits, so that stretching produces a flat film in the form of a network or a row of interconnected tapes, respectively; the film may be such that the apertures between the resulting ribbons are of substantially zero width. Such films having an unslitted border portion are described and claimed in Specification 1,378,750. (2) Two films are slit, one laterally and one longitudinally, and are laminated. (3) Two films are longitudinally slit and are laminated after one has been stretched laterally and the other longitudinally. (4) Two films are stretched, one laterally and the other longitudinally, and are fibrillated before laminating. (5) Two embossed films are each stretched laterally and longitudinally before laminating. (6) The film of interconnected tapes mentioned in (1) is laminated as a central layer between two similar layers whose tapes have been produced by longitudinal slitting and stretching and which are offset relative to the other, so that the product resembles a fabric. In the above embodiments longitudinally oriented films should be maintained under longitudinal tension for laminating. Slitting may be performed by heated knives carried on a roller and may be facilitated by using a freshly-extruded film. Embossing may be performed by a roller immediately after extrusion of the film or after heating to soften the film. Suitable fibrillation techniques are disclosed.

Abstract: 1287996 Controlling reactors SIEMENS AG 9 Dec 1970 [10 Dec 1969] 58542/70 Heading G6C A control rod driving assembly comprises a drive rod for transmitting axial drive to a control rod from a prime mover releasably coupled to one end of the drive rod, with the control rod coupled to the other end, so as to vary the degree of insertion of the control rod in the reactor core, and resilient means arranged so as to impel the drive rod axially away from the prime mover towards the core, upon release of the coupling between the prime mover and the drive rod, with a force which is greater the smaller the degree of insertion of the control rod at the instant of such release. For example, a lifting rod 3 connected to a driving motor (not shown) has secured to its lower end an electromagnetic coupling device 4 which engages an armature plate 41 secured to the upper end of an elongate drive rod 42, from the lower end of which a control rod (not shown) is suspended. An impelling spring 51 extends between a plate 52 carried by a stop 43 on the drive rod 42 and the end wall of a tubular housing 5. A projection 53 on the lateral wall of the housing 5 bears on a stop 21 inside a guide tube 2. The compression of the spring 51 is inversely proportional to the extent to which the control rod has penetrated into the reactor core. In an emergency, the electromagnetic coupling 4/41 is released and the armature plate 41 is pulled away by the force of the spring 51 and accelerated downwards together with the drive rod 42 and the control rod. When the plate 41 engages the end wall of the housing 5, the spring 51 ceases expanding and is carried downwards by the plate 41. At the end of the downward movement, the plate 52 engages an abutment ring 7 and the spring 51 is compressed (Fig. 3, not shown), thus slowing down the drive rod 42. The remainder of the kinetic energy of the driving assembly is absorbed by shock absorber springs 6, e.g. dished or ring springs, when the housing 5 bears on the ring 7. To re-start the reactor, the electromagnetic coupling 4 is again coupled to the armature plate 41 and then raised. The upward movement of the housing 5 ceases when the projection 53 engages the stop 21, and from then on the spring 51 is increasingly compressed by the further upward movement of the drive rod 42.
