Abstract: LEAD-IRON PHOSPHATE GLASS AS A CONTAINMENT MEDIUM   FOR THE DISPOSAL OF HIGH-LEVEL NUCLEAR WASTES                   ABSTRACT OF THE DISLOSURE Lead-iron phosphate glasses containing a high level or Fe2O3 for use as a storage medium for high-level radioactive nuclear waste.  By combining lead-iron phosphate glass with various types of simulated high-level nuclear waste, a highly corrosion resistant, homogeneous, easily proceased glass can be formed.  For corroding solution at 90°C., with solution pH values in the range between 5 and 9, the corrosion rate or the lead-iron phosphate nuclear waste glass is at least 102 to 103 times lower than the corrosion rate or a comparable borosilicate nuclear waste glass.  The presence or Fe2O3 in forming the lead-iron phosphate glass is critical.  Lead-iron phosphate nuclear waste glass  can be prepared at temperatures as low as 800°C., since they exhibit very low melt viscosities in the 800 to 1050°C. temperature range.  These waste-loaded glasses do not readily devitrify at temperatures as high as 550°C. and are not adversely affected by large doses of gamma radiation in H2O at 135°C.  The lead-iron phosphate waste glasses can be prepared with minimal modification or the technology developed for processing borosilicate glass nuclear wasteforms.

Abstract: A B S T R A C T     A counterweight (12) provided at the end of a shaft (8) for winding up the door-raising belts (3) of a concertina type door.  The counterweight (12) is designed to open the door to a fraction of its height.  It co-operates with the motor (7) when the door is being opened and closed under normal circumstances.          A motor and brake unit (14) is provided including both the motor (7) and a brake for locking the shaft (8) when the motor is not in operation.  Catch means may also be provided on the bottom of the door.  Manual means are provided for releasing the shaft-locking brake means in the event of a power failure.          The device is essentially a safety device and in the event of a motor breakdown or a power failure it enables the concertina-type door to be rapidly opened, at least partially.  Similarly, in the event of the coupling between the drive shaft and the motor being broken, the device prevents the door from falling to its closed position in a catastrophic manner.  The device also makes it possible to use a motor of smaller power than would be required in an installation which does not include a counterweight.

Abstract: Abstract of the Disclosure A frequency synthesizer comprises a voltage control generator (11) for generating an output signal of a desired frequency in response to a control signal and a reference signal generator (13) for generating a reference frequency signal.  The output signal is sampled (21) by the reference frequency to produce a sampled signal.  The reference frequency signal is frequency divided (22) by a division factor determined by the desired frequency and the reference frequency.          The sampled signal and the divided signal is compared (15) in phase and frequency and the control signal is produced depending on the phase difference between the both signals.  For the division factor, two different values are determined by the desired frequency and the reference signal and one of the two values is selected according to a selection pattern determined by the reference frequency and the desired frquency.  A control circuit (41) calculates the two values and a multistage frequency divider (42) generates the selection pattern signal under control of the control circuit (41).

Abstract: OPTICAL FIBER SIGNAL TEST CLIP     Abstract The invention relates to a hand-held device for detecting whether or not an optical fiber is carrying a light signal.  The device includes a spring loaded hook for grabbing an exposed optical fiber anywhere along its length, thereby introducing microbending, a photodetector for responding to the presence of light emitted in the proximity of the microbend, and a light emitting diode connected by way of an amplifier to the photodetector for indicating when a light signal has been detected.  Upon release of the spring loaded hook, the fiber returns to its normal state.  The device can be easily modified to indicate not only the presence of a light signal, but also the strength of the signal and the direction in which the signal is being transmitted.

Abstract: ABSTRACT            Many attempts have been made to design a suitable computer architecturefor processing production systems in parallel and/or in real time. This invention is a processor that can execute production systems such as expert systems or rule based algorithm in real time by processing the rules in parallel. it is based on an arrangement of special gates that permit the firing of several rules concurently. It also does the match of the premisses of rules with the input or conclusions of fired rules in parallel. Once programmed with a production system, the arrangement of gates becomes an analog processor for that particular production system. Several variation or improvement are possible for application to particular fields such as control systems, expert systems, logic programming. The differences permit simpler designs when backward chaining, negation or arithmetic capabilities are not needed.
