Title: Tube connector for flexible plastic tubes - for transporting compressed air, oil, water or other media
IPC: F16L37/092
Filed: 1973-07-12
Abstract: Connector for rapidly connecting flexible tubes, mainly plastic tubes, comprises a housing with a penetrating bore with a coaxial cylindrical widening on one side, in which a sleeve is mounted using a press fit. The innermost wall surface of the sleeve directed to the interior of the tube connector is conical, and the innermost wall surface directed to the end of the tube connector is cylindrical. A cylindrical organ in this sleeve is slidable longitudinally and has a bore for inserting the piece of tube.

Patent NL-7612711-A (NL)
IPC: G10L25/90
Filed: 1976-11-16
Abstract: A detection circuit for the significant peaks of a speech signal, comprising first and second detectors respectively for detecting the positive and negative peaks of said speech signal. Each of these detectors is followed by a peak charging circuit comprising a first integrator having a relatively large discharge time constant and a comparator comparing the detected speech signal and the output signal of said first integrator. Each peak charging circuit comprises in addition a second integrator having a relatively small time-constant. The discharge of the first integrator is effected up to a voltage equal to the output voltage of the second integrator, and the discharge of the second integrator is effected down to a voltage depending on the output voltage of the first integrator. The two integrators of each peak charging circuit provide a non-exponential decreasing signal which has an inflection point following a significant peak in the original speech signal.

Title: Magnetic tape cassette system - presses cassette slid into carrier against head assembly and tape drive shafts by spring-loaded push-button assembly
IPC: G11B15/29
Filed: 1981-04-13
Abstract: This magnetic tape recording system is more suitable for high fidelity sound reproduction than conventional micro-cassettes. It can have facilities for automatic changing of cassettes. The manually-operated system consists of a drive unit (2), head assembly (4), cassette (1) and cassette carrier (21). The cassette slides into the carrier and is pressed up against the head assembly (4) and tape drive shafts (11,12) by a spring-loaded push-button assembly (37,38,39). The automatic cassette-changing system uses a gearwheel mounted at the back (23) of the carrier to mesh with grooves on the back of the cassette (25), and to drive the cassette into the player. Similar gearwheels on either side of the carrier then mesh with the side-walls of the cassette to force it against the head (4) and drive shafts (11,12).

Patent NL-8501529-A (NL)
IPC: G01F1/44
Filed: 1985-05-29
Abstract: An apparatus for measuring a gas mass flowing through a pipe per unit of time comprises a constriction (5) into which a pin (6) is inserted which may be moved a greater or lesser distance into the constriction thereby varying the smallest section of the constriction. The constriction is intended for the passage of gas through it at sonic speed. If the area of the sonic section and the nature of gas are known, only the total pressure and temperature will have to be measured in order to enable the mass flow to be calculated. For an accurate measurement of the total pressure and upstream of the constriction the gas should have come to rest. Therefore upstream of the constriction a stilling chamber 7 of relatively large section is disposed and this stilling chamber contains the means (8, 9) for measuring the temperature and pressure. Further the constriction is bounded by a truncated De Laval jet pipe (4).

Wedge shaped polyester epoxyresin and wear proof lights are placed in the top or side edge of the flap or in the telescopic end of the flap which can reach the ground after telescoping. No part of the lights extends outside the surface of the flap or beam and they are mfd. from a hard reinforced transparent plastics material. Each contains an electric bulb with cables running to the vehicle battery via a spring switch and grooves in the flap or beam. On flapping open or telescoping out, the spring switch closes and light shines on the edges of the tailboard or load beam.

Title: Television display system with reduced line-scan artifacts
IPC: H04N5/44
Filed: 1982-08-23
Abstract: A flat-field television image having reduced visibility of horizontal scan lines is generated by receiving first and second fields of interlaced video and progressively generating a scanned image within a time for one incoming field. The progressively scanned image contains interstitital lines between the lines of one field, and consequently the line-scan structure is made less visible, but the flicker rate is undesirably decreased. In order to increase the flicker rate, additional progressively scanned images are generated at a rate equal to or greater than the incoming field rate.
