Title: Blasting mat made of olefin polymer or rubber tubes
IPC: E01C5/20
Filed: 1969-09-15
Abstract: Blasting mat for dampening detonation waves and preventing rock splinters or debris from spreading, consists of parallel tubes of flexible material wired together. The mat is lighter than the usual mats made from old motor tyres, and also lasts longer and is easier to handle since it can be rolled up. The preferred materials for the tubes are olefine-polymers or rubber. Tube or hose lengths placed side-by-side to form a rectangular mat, are connected together by wires passed transversely through holes at right-angles to the tubes. Reinforcing wires are threaded lenthwise through the tubes and end loops of these wires are used to join adjacent mats together. The mats hinge about this joint to absorb the blast. The tubes can be closed at the ends and filled with sand.

Patent NL-7705734-A (NL)
IPC: G10L25/87
Filed: 1977-05-25
Abstract: In a speech recognition system of the type including a recognition unit responsive to a voice input and a conditioning input for recognizing the voice input to produce a recognition output, a start signal is produced whenever a voice input exceeds a threshold level and a pause interval detection signal is produced whenever a voice input falls below a threshold level. An output timing signal is produced when the detection signal lasts a preselected interval of time that may be either about 250 milliseconds or about 250 milliseconds plus a delay. The recognition output from the recognition unit produced in response to the detection signal is displayed in response also to the detection signal. The result is delivered to a utilization device in response to the output timing signal. The delay may be given either by a predetermined duration or an interval between those instants at which the above-mentioned 250 milliseconds have just elapsed after production of the detection signal and after production of another pause interval detection signal for a next following voice input. During the delay, it is possible either by a manually operable switch or a cancel voice input to cancel delivery of the recognition result displayed to be incorrect.

Title: Sample core drilling unit has outer barrel with drill bit - rotatably contg. inner barrel with core catcher axially movable against spring
IPC: E21B25/00
Filed: 1982-03-05
Abstract: The core drilling unit (1) comprises an outer core barrel (5), which is secured at the lower end of a drilling string and, at its lower end, carries (4) a core drill head (2,3), and an inner core barrel (17) which is rotatably carried (via 13-16) by a swivel (9;10-12) and, at its lower end, carries (22) a core catcher (23). The lower end (24) of this core catcher extends by a small amount below the level (H) at which the annular downward mud passage (26) around the catcher enters a portion (29) with reduced cross-sectional flow area. The inner core barrel is axially movable relative to the outer barrel against spring force (upward to H against spring 31 and possibly downward to L against spring 32). Used as drilling unit to take core samples (35) in underground formation (33). The arrangement gives clear indication if, e.g. through fracture of the core, this can no longer move upwards in the inner barrel, as the catcher is raised (H) and the mud pressure suddenly drops by the flow constriction (29) being eliminated. Drilling is then stopped and damage to the core and to the inner barrel (if in plastic) prevented.

Title: Dust collector for silo ventilation
Inventor: ROMME ADRIANUS JOHANNES CORNEL
IPC: B65G69/18
Filed: 1995-03-24
Abstract: The invention relates to a device for collecting and processing dust which is formed when filling storage silos, for example for animal fodder. For this purpose, a dust collector is attached to the ventilation system of the silo, which dust collector is rigidly coupled to a pipe conveyor for conveying animal fodder to the animal sheds. The dust collector (dust trap) may be provided with a cyclone. The dust-collecting space of the dust collector is connected to the interior of the pipe conveyor. When the pipe conveyor is switched on, it will transmit vibrations to the dust collector and the dust will be entrained in metered form with the animal fodder. The air filter will to some extent have a self-cleaning action due to the air movements in the ventilation system.
