Title: Optical energy sensor and demodulation system
IPC: G01J3/26
Filed: 1982-05-31
Abstract: The signal energy to be sensed or detected is caused to stretch an etched single mode fibre. An etched single mode fibre is a single mode glass clad fibre whose cladding thickness has been reduced a specific amount so as to lower its strength. The invention provides that, when necessary to maintain the etched single mode fibre's light guiding properties, the portion of the glass clad which was removed is replaced with a plastic material whose optical index is lower than that of the single mode fibre's core material and whose elastic modulus is lower than that of the glass clad which it replaces. - Such an etched single mode fibre is more sensitive to stretching or compression because it is weaker. For a given amount of signal energy, a single mode fibre will stretch a greater amount after it has been etched. The sensor is used in a hydrophone array.

Patent ES-8502586-A1 (ES)
Title: Pager decoding system.
IPC: H04W88/02
Filed: 1984-02-22
Abstract: A pager decoding system which is suitable for use with signal formats, such as POCSAG, in which code words are sent in batches, each batch containing a synchronization code word and (n-1) address/message code words, n being the number of code words in a batch, each code word comprising m bits. The pager is able to detect or regain synchronization code word when the carrier signal is lost due to fading. When synchronization is lost input data received by the pager is combed through by switching-on the pager for a duration of m bits at intervals corresponding to (n+1) code words. The data received is stored in a shift register having m stages and in which a synchronization code word can be assembled within two batch periods. Once the synchronization code word has been detected the pager can be switched to a normal data receive mode. In another fade recovery mode the (m-1)th, mth, and (m+1)th bit positions every nth code word are searched to see if a preamble or synchronization code word is present. If none is detected after a predetermined number of batches has been searched then the pager assumes the loss of synchronization mode described above.
Patent ES-8500662-A1 (ES)
Title: Method and apparatus for joining optical fibres.
IPC: G02B6/36
Filed: 1984-03-08

Patent ES-8507697-A1 (ES)
Title: Broadband doppler simulator
IPC: G01S7/52
Filed: 1984-04-30
Abstract: A broadband doppler simulator is described in which signals from a plurality of hydrophones are simulated by selecting storage addresses of a random access memory whose successive addresses contain samples of an input signal. The range of each hydrophone from the target whose signal it is receiving is determined by the address assigned to the hydrophone relative to the address of the input signal in the random access memory. In order to produce a doppler shift (time compression/expansion), the address of the simulated hydrophone signal is changed with respect to the signal which is being stored in the memory. The rate at which the address of the simulated hydrophone signal is being changed relative to the input signal determines the doppler shift. In order to reduce the size of the random access memory while retaining the ability to change the apparent doppler shift with a higher resolution as well as maintain signal distortion below an acceptable limit, an interpolation technique is used to obtain signals corresponding to delays which are smaller than the delay between adjacent addresses.

Patent ES-8503750-A1 (ES)
Title: Method and apparatus for continuously treating textile materials in rope form.
IPC: D06B3/28
Filed: 1984-06-27
Abstract: The crease displacement and the achievable dilution factor in the conventional continuous pretreatment or aftertreatment operations of fabric ropes with liquid means in rope washers are not adequate, and consequently the water consumption necessary for satisfactory results is too high. To date the existing problems can only be solved with squeeze rollers which, however, have an adverse effect on the goods. According to the invention the textile rope is now introduced into a treatment store of a liquid-operated jet apparatus, is subjected to the action of the treatment liquor, is then carried along by a steam- or more generally gas-operated jet arrangement and conveyed into an interim store, where dewatering takes place. From the interim store the goods, with satisfactory dilution factor, are then passed to the next isothermal or non-isothermal treatment stage of the same or a very similar structure.
