Patent CA-2102880-A1 (CA)
Inventor: GOLLADAY STEVEN D
IPC: G01R31/26
Filed: 1993-11-10
Abstract: A method for measuring electrical characteristics of an  electrical  device  having  a  conductive  structure associated therewith involves the sequence of steps as follows:  First,  employ  a  low  energy electron beam  to charge  all  conductors  on  the  surface  of  the  device. Expose  individual  conductors  to  a  focussed  low energy electron beam serially. Make measurements of an induced current signal when individual conductors are exposed to the  focussed  electron  beam.    Analyze  induced  current measurements  derived  from  the  individual  conductors. Then determine electrical characteristics of the device based on the analysis.  A charge storage method and three capacitive test methods for defect detection and methods for shorts delineation are described.

Title: Ranging method for use in tdma systems on tree-and-branch optical networks
Inventor: MOSCH THEO W M
IPC: H04B10/272
Filed: 1993-08-23
Abstract: Ranging Method for use in TDMA Systems on Tree-and-Branch Optical Networks Abstract In a passive optical free-and-branch network, which utilizes the Asynchronous Transfer Mode (ATM) transmission format, a superimposed low-level, single frequency, ranging signal is used to determine the distance between an Optical Line Termination (OLT) node and any Optical Network Termination Node (ONT) of the network. In one embodiment of the invention, this ranging frequencyis a low frequency signal that is superimposed on top of the transmitted data signal from the OLT. This ranging signal is returned to the OLT from a particular ONT upon the issuance of a ranging command from the OLT. The phase difference between the transmitted ranging signal and the received ranging signal is proportional to the distance between the OLT and that particular ONT. In a second embodiment of the invention, the ranging signal is a high frequency signal that is superimposed on top of the transmitted data signal from the OLT. This ranging signal is returned to the OLT from a particular ONT upon the issuance of a ranging command from the OLT. The time between issuance of the ranging command and reception from that particular ONT of the ranging signal is proportional to the distance between the OLT and the ONT.

Abstract: It is applicable to the recovery mainly of pastry goods, such as cookies, biscuits or the like, packaged in cardboard, plastic or the like, which may also include staples, nails or other fastening and sealing elements. The raw material in bulk is received in a hopper (1) from which it is led by means of an Archimedean screw (2) to a hammer mill or the like (4) in order to be ground. After passing through some grids it is collected by a second helicoidal screw (6), whose covering frame (7) has in its final section a grating (12) that defines a screen where the useable material in the form of grain or flour is separated by gravity. The unuseable material and that still contains particles of edible material passes to a trommel (8), at the outlet of which there is an absorption device (9) of the unuseable material. In the top part of the hammer mill (4) there is a device with magnets (5) to remove the possible staples, nails, etc. The compact or metallic remains that come out of the trommel (8) and which are not collected by the absorption device (9) are returned to the grinding mill (4.) <IMAGE>

IPC: A01K5/00
Filed: 1995-02-14
Abstract: In the care of herbivorous, ruminating livestock there are many types of systems and units available to provide the same with minerals and salts that are necessary for their diet. Since these animals are often attacked by biting insects, the same or different units incorporate insecticide wicks or spays that transfer insecticide to their bodies and help provide relief from the same. At the same time, any unit which may provide these needs to livestock must also provide protection to the minerals, salts, and insecticide from weather contamination. In this invention a unit is manufactured which provides all this and at the same time is sturdy enough to withstand the pushing and scratching action which is common among large livestock and also answers two concerns very common among livestock producers. One concern is environmental and is answered by re-using the 20 liter plastic containers which contain many products which livestock producers and all farmers purchase. Another concern is, that if one of the plastic containers of the unit which contain the minerals, salts, or insecticide should be damaged or destroyed by the livestock, the producer would have a ready, economical replacement whenever necessary.
