Patent CA-2114108-A1 (CA)
Title: Modular closing resistor
Inventor: FREEMAN WILLIE B
IPC: H01H33/70
Filed: 1992-06-29
Abstract: A modular closing resistor assembly (20) can be added in line with the interrupter assemblies (16) of an extra high voltage circuit breaker and has a relatively short length. The resistor element consists of two stacks (70, 71) of disks which are disposed side by side and are electrically connected such that the alternate disks (72, 73, 74) of each stack are connected in series with one another. The operating mechanism of the unit includes a linearly moving roller (120) which engages a crank arm (110) which is in turn pivotally connected to op-erate the movable closing resistor contact (52) with a motion and with a variable mechanical advantage adapted to cause the resistor contacts (52) to close a high speed just after the interrupter contacts close and to open after the interrupter contacts open.

Title: Fluorescent lamp ballast
Inventor: GARBOWICZ GLENN D
IPC: H05B41/24
Filed: 1994-02-04
Abstract: ABSTRACT: Fluorescent lamp ballast.     A starting capacitor disconnect scheme for a fluorescent lamp in which each starting capacitor shunts one or more fluorescent lamps until all fluorescent lamps are ignited. Following ignition of all fluorescent lamps, each starting capacitor is effectively removed from the ballast. Preconditioning of the fluorescent lamp filaments can be limited to the period of time that one or more lamp loads are shunted by the starting capacitor.

Title: Underwater light scattering sensor
Inventor: BARTZ ROBERT
IPC: G01N21/49
Filed: 1994-03-22
Abstract: ABSTRACT OF THE DISCLOSURE An underwater light scattering sensor is disclosed that includes a light source, light stop and a light detector mounted on a planar support capable of measuring nearly all suspended particle concentrations found in natural waters, 1 µg/l to 3 g/l. The sensor is designed to measure light scattered at nearly all angles, which includes forward scattering, back scattering, and multiple scattering, from suspended particles in water through a very short light path length. The small and simple design of the sensor allows it to be produced at low cost, permitting its use in both expendable and non-expendable applications for the detection or measurement of suspended particulate concentrations in water. The magnitude of the scattered light measured by the sensor is proportional to the suspended particle concentration in water, provided the nature of the particles does not change.

Title: Fiber-optic amplifier with a device for monitoring the input power
Inventor: HEIDEMANN ROLF
IPC: H04B10/079
Filed: 1994-03-24
Abstract: Abstract of the Disclosure The input light in fiber-optic amplifiers is monitored in order to turn off the system in which it is contained, or individual components of the system, e.g. the fiber-optic amplifier itself, when input light is lacking. To that effect, in known fiber-optic amplifiers, a portion of the input light is coupled out by a coupler. However, this coupler has disadvantages; e.g. the signal-to-noise ratiodeteriorates. To monitor the input light, the fiber-optic amplifier of the present invention uses a device (4), which couples out and evaluates the pump light thatwas not absorbed by the section of the optical waveguide (2).

Title: Method for transporting cocoa beans in loose form
Inventor: FALCO SERGIO
IPC: A23G1/06
Filed: 1994-11-10
Abstract: ABSTRACT    An improved method of transporting cocoa beans to chocolate manufacturers in loose form, a way not presently done, through the use of a transfer station.  At the transfer station the cocoa beans are unbagged or unpacked and cleaned by removing all impurities that are packed with the cocoa beans.  Thereafter, the cocoa beans are stored in silos located at the transfer station and are then loaded into hopper rail cars or hopper trucks for transportation to the chocolate manufacturers for immediate use in the chocolate making process,  allowing them to save on transportation costs, labor costs, storage costs, and allow them decrease the amount of property or space needed to operate a chocolate manufacturing plant.  The improved method also saves the chocolate manufacturer machinery and maintenance costs as well as time.
