Title: Air-collecting balloon for sampling air at high altitude
IPC: G01N1/22
Filed: 1968-02-23
Abstract: A tetrahedral balloon for collecting air at high altitudes (e.g. from 3000 to 33,000 metres) comprises an inflatable tube 3 forming a triangular frame, a flexible tube 7 extending from the plane of that frame to a fourth apex weighted by a metal strainer 15, and a flexible skin 1. At ground level before ascent the tube 3 is partially inflated, the remainder of the balloon being collapsed, the tube 7 being pulled inside-out through a rigid ring 11 as far as the strainer 15 which is held against the ring by a release device 17. This balloon is then suspended below a carrier balloon by cables 19, 43, 45 and lifted, the tube 3 stiffens, and to prevent over-inflation it is equipped with safety valves mounted on rigid vertical tubes 27 at the comers. The release device 17 acts after a time delay so that at an appropriate height the strainer 15 is released, and by its weight it pulls the balloon to the shape shown, drawing in the ambient air through the tube 7 and the strainer. The balloon is then released from the carrier balloon and allowed to,fall.

Patent ES-372606-A1 (ES)
Title: A weft stop motion for a loom
IPC: D03J5/00
Filed: 1969-10-16
Abstract: A weft stop motion comprises a signal transmitter in the shuttle including a thread sensor 10 controlling an active electronic component, a signal receiver outside the shuttle for controlling the means for stopping the loom, and first and second devices located respectively alongside the path of the shuttle and in the shuttle, which devices are not in electrical contact but interact temporarily, during the shuttle movement, to provide electrical energy for the electronic component in the shuttle. The weft sensor comprises a friction plate 10 over which the thread runs, thereby generating an electrical signal in a conductive plate which is transmitted to an amplifying transistor 25 energised by electrical pulses produced when a coil 15 carried by the shuttle passes a stationery permanent magnet 21 carried by the batten and situated inside a coil 17 forming a signal receiver. The signal produced by the action of the weft on the plate 10 is transmitted by coil 15 and picked up by coil 17. Filter 29 separates the part of the signal produced by the thread and filter 34 that due to the supply voltage pulses, and after amplification and pulse shaping, two pulses are fed to a carrier device 36 which only produces an output pulse if both signals are present, indicating the presence of weft. This pulse is fed to a device 37 and cancelled therein by a pulse from a generator 38 actuated by the loom drive mechanism, whereby the stop motion mechanism 40 is not operated. If the weft is broken, no signal is produced by the device 36 and a pulse is emitted by the device 37 to actuate the stop motion mechanism. Separate coils may be provided in the shuttle for generation of supply energy and transmission of signals and the supply energy may alternatively be generated by a beam of light cooperating with a photoelectric device in the shuttle or by an alternating current in an induction coil.
