Patent ES-355233-A1 (ES)
Title: Method of pulse shaping and renewable duration variable pulse-shaping circuit for the application of said method
IPC: H03K5/00
Filed: 1968-06-20
Abstract: A method of lengthening a pulse comprises transmitting each incident pulse t 0 to a sealer 18 for resetting the sealer 18, directing the resultant signal 28 to a re-cycling pulse generator 30, re-cycling pulses from generator 30 to the sealer 18 until a predetermined number has been registered and converting (at 32 and 36) to a single long pulse, the successive pulses from generator 30. The circuit described operates at intervals between a few tens of nanosecond and a few microseconds, the sealer 18 being reset by further input pulses occurring during the long output pulse so that the resulting output pulse ends at the predetermined time after the last input pulse. As shown, each pulse at 14 triggers a univibrator 20 giving a pulse of duration p which is delayed at 22 before triggering a second univibrator 24, the output of which resets the scaler 18, comprising three bi-stable circuits. An output from each stage of the sealer 18 is coupled via an OR gate 28 to initiate the re-cycling pulse generator 30, the frequency and duration of which may be adjustable by variation of delay lines (not shown). After shaping at 32 and 34, pulses ta . . . t g are passed by a gate 26 (blocked during period p) to the counting input of sealer 18. After a count of 7, the output from the OR gate 28 no longer allows generator 30 to pulse, hence the pulse train is terminated. The smoothing circuit 36 delivers a single pulse output at 35 of duration equal to that of the train of pulses from 30. Figs. 5-9 (not shown) explain the operation following receipt of input pulses at 14 of various time separations. Figs. 1, 2 and 10 (not shown) relate to the use of the invention in an anticoincidence circuit.

Title: Improvements in and relating to shielding containers
IPC: G21F5/08
Filed: 1969-03-28
Abstract: In a shielded container for transporting radioactive substances, thermal insulation is provided to afford protection against external fire. In Fig. 1, the radio-active substance 5 is surrounded by the lead wall 2 within the steel envelope 3. To provide thermal insulation the bands 9, and slab 10, formed of asbestos, cement composition or a water-saturated substance, are mounted between 2 and 3. Mechanical shocks are absorbed by the lead mass contacting the envelope 3 between the zones 9, 10. In a modification the container is cylindrical. In an alternative form, Fig. 4, a conventional container 28 for transporting radio-active substances, may be mounted inside the concentric steel envelopes 30, 31 which are separated by wood blocks 32 and thermal insulators 33.

Title: Stack preheater
IPC: F27B7/20
Filed: 1969-04-23
Abstract: A shaft heat exchanger 1 for pre-heating or drying falling granular or pulverulent material by means of a rising gas stream incorporates a continuous helical surface 2 forming a downwardly facing acute angle (V, Fig. 1) with the shaft wall and decreasing in pitch in the upward direction of the shaft. As shown, the heat exchanger is a preheater for heating cement raw material in a rotary kiln plant (see Fig. 3, not shown). The flow of material through the shaft can be controlled by the inclusion of a vertical frusto-conical member 5 arranged to regulate the width of the continuous gap formed between the inner edge of the helical surface and the member 5. In a modification, Fig. 4, the shaft is provided with a second helical surface 21 extending between the radially inner edge 20 of the surface 2 and the shaft wall, as shown. This arrangement permits part of the shaft wall to be removed and replaced by vertical structural bars 25.

Title: Self-test apparatus for facsimile graphic communication system
IPC: H04N1/00
Filed: 1969-06-16
Abstract: A self-test facility for a document facsimile transceiver, e.g. of the Telecopier type, comprises means, including an enabling switch 66, for energizing both the scan circuitry 62 and print circuitry 64 and coupling means, such as a dummy telephone headset 78 which produces audio coupling between transmit and receive transducers 82, 84 in an acoustic coupler 36, for coupling the output of the scan circuitry 62 to the input of the print circuitry 64. The scanning part of the transceiver, in this case comprising two scanning heads 24, 25 on a rotating turret scanner unit 4, scans a test label fixed to a test document 59 and the printing part, in this case impact printing heads 34, 35, simultaneously reproduces the image of the label elsewhere on the document 59 for comparison with the original. The acoustic coupling arrangement may be replaced by electrical coupling, e.g. inductive in nature. The test document 59 may use a carbon, or other colorant, paper or a system involving the use of encapsulated colouring fluid. Alternatively the impact printing arrangement may be replaced by electrolytic or electrostatic printing means.

Title: Fluid flow control instrumentality
IPC: F15B21/044
Filed: 1969-07-11
Abstract: In a valve mechanism for controlling doubleacting motor 7, fluid pump 12 passes via check valve 18, passage 15 and line 17 to chamber 16 whence it is admitted to one side or the other of the motor upon raising of spool 19 or 20 by actuation of pilot valve 8 to pressurize port C1 or C2. The other port is simultaneously depressurized to allow the other spool to be lowered by work port pressure applied there above via 34, 35 to exhaust the other side of the motor. When the motor is acting against a load, delivery pressure at 15 is high and acts via 60 on plunger 61 to unseat valve 51 to provide an exhaust path via 30, 53, 52, 13. When the load assists the motor pressure at 15 falls whereas that at 52 rises and the pressure differential across valve 50 eventually unseats the latter to allow the exhaust fluid to flow to 15 thereby supplementing the pump output and preventing void formation in the motor. The exhaust fluid also flows via 67, 68, 57, 69 to assist in keeping pilot operated pump unloader valve 48 closed, and via 43 and pilot valve 8 to assist in keeping the operative spool raised. In Fig. 2, pressure rise at 52 eventually moves valve 80 leftwards and acts in chamber 57 to bias relief valve 72 closed. Valve 80 may be embodied in the relief valve.
