Patent ES-335818-A1 (ES)
Title: Method and apparatus for assaying the lithium isotope of mass no.6
IPC: G01N23/22
Filed: 1967-01-19
Abstract: The lithium-6 content of a sample is measured by directing on to the sample a beam of deuterons and detecting the [alpha] particles produced by the reaction Li6 + d # 2[alpha] which are simultaneously emitted by the sample in directions corresponding to opposite directions in the centre of mass system and with energy within a given range. Collimated 700 keV deuterons from an accelerator impinge on a carbon or plastics holder carrying a film of material to be analyzed for Li6. Silicon junction detectors 10, 10' located at 85 degrees to beam direction detect [alpha] particles emitted at right angles to the beam in the centre of mass system. The outputs of detectors 10, 10' are fed via amplifiers 14, 14' 16, 16' and single channel pulse height analyzers 18, 18' to a coincidence circuit 20, which gives an output pulse only when detectors 10 and 10' simultaneously receive [alpha] particles of the same energy. A pulse height analyzer 26 may be provided to determine the height difference between spectrum peak and the background level and apply a signal to scaler 22 to compensate for background. In order to compensate for variations in the deuteron beam intensity the same may be measured by a Faraday cage 23 which receives the beam after it has passed through the sample and feeds a current integrator 24. In a modification Fig. 2 (not shown), the deuteron beam intensity is monitored by scattering some of the deuterons which have passed through the sample on to a silicon junction detector by means of a gold foil.

Patent ES-363755-A1 (ES)
Title: Manufacture of polymeric tubular films
IPC: B29C48/10
Filed: 1969-02-17
Abstract: A tubular film has a wall having at least three layers which are formed alternately of different polymers and which, as exposed in a transverse cross-section of the tubular film, have at least over part of the film's circumference a spiralling shape, the layers defining the inner and outer wall surfaces being each formed of a single polymer. The spiralling part of each layer may extend through an angle of at least 360 degrees. The thickness of at least one of the surfacedefining layers may differ from, and may be at least 50% thicker or thinner than, any one of the layers of spiralling shape. To make such a tubular film in which the surface-defining layers consist of different polymers, two streams of different polymer are fed, Fig. 1, via adjacent passages 20, 21 respectively to annular chamber 14 between housing 3 and rotor 6. The streams, rotating side by side with rotor 6, flow through chamber 14 and are extruded through an annular slot 17 to form the film 30, Fig. 3. The outlets 25, 26 of passages 20, 21 are elongated in a direction parallel to the axis of rotation of rotor 6. Alternatively, the two polymer streams may be fed into one end of the annular chamber, one stream being eccentrically disposed with respect to the chamber's axis and being surrounded by the other stream, or two polymer streams may be fed through a stationary mandrel to an annular chamber formed between the mandrel and a rotatable housing surrounding the mandrel. To make a film in which the surface-defining layers are formed of the same polymer, two streams of different polymers are fed, Fig. 4, into one end of an annular chamber between rotor 37 and housing 39 via ports 40, 41 respectively. The two streams, one surrounding the other, are rotated and fed along the chamber to be extruded through an annular slot. The extruded tubular films may be inflated.

Title: Tdm telecommunication system designed for transmission of supervisory signals
IPC: H04J3/12
Filed: 1971-07-13
Abstract: To indicate the active or inactive condition of any one of a group of n telegraph lines transmitting in interleaved relationship over a common channel, each line is assigned a 5-bit time slot in a recurrent cycle of n+1 time slots, the extra slot being utilized at the beginning of each cycle to register the 4-bit address of the first nontransmitting line in the series which is either idle (stop signal) or about to become active (start signal). In the time slot of the line so identified, a discriminating bit differentiating between "start" and "stop" conditions is accompanied by the four address bits identifying the next nontransmitting line in the series, and so forth the extra time slot eliminates the need for a 6th bit to accommodate the start and stop signals in a 32-character telegraphy code.
