Patent WO-8600953-A1 (WO)
Title: Gate systems
Inventor: CARROLL NOEL
IPC: E05F15/20
Filed: 1985-07-30
Abstract: A gate system comprising two parallel barriers (2), (4) defining an entryway into a zone. A gate (6) is pivotal about an upright axis at one side of the zone and is movable between a closed position at which it extends across the zone and open position at which it extends in the direction of the zone adjacent one barrier (2). The gate (6) is driven from a motor (20) via a flexible coupling (22), a gear box (24) and a coupling device (26) and a spring loaded clutch (28). When the gate (6) is at its closed position the gate is locked in that position by locking the coupling device (26). The gate can, however, be moved to its open position notwithstanding this locking by application of force to the gate whereby to exert sufficient pressure to release the spring loaded clutch (28). Approach of persons towards the gate system, in an intended allowed direction of passage therethrough, at the entrance (10) thereto, is detected by use of a photocell (12) which causes the gate to be moved to its open position for a predetermined period and then reverted to its closed position. Approach of persons to the exit side (16) is detected by a detector arrangement (14) effective to generate an alarm, when such approach is detected.

Patent WO-9103850-A1 (WO)
Inventor: HILL PETER COLLIN
IPC: H01S3/225
Filed: 1990-09-06
Abstract: It has been discovered that short-lived dimer ions are created in a noble gas under high energy conditions, such as during an electrical discharge. These noble gas dimer ions have excited energy states which make them suitable for use as the gain medium in a laser. A laser created using noble gas dimer ions as the gain medium exhibits a high degree of efficiency, is tunable over a broad range of wavelengths, and may be capable of being operated continuously.

Abstract: ABSTRACT OF THE DISCLOSURE           A two-stage process for purifying wasetwater includes the  steps  of  biophysical  anaerobic  treatment  to  remove  the majority of the COD, followed by biophysical aerobic treatment to further purify the wastewater.  A powdered adsorbent, preferrably powdered activated carbon, is used with biological solids in each treatment step.  Excess biophysical solids from the aerobic step are transferred to the anaerobic step for digestion.  Fresh powdered adsorbent is added to the aerobic treatment step to compensate for that transferred to the anaerobic treatment step.          Solids concentration in the anaerobic step is controlled by wasting solids to disposal.
