Title: Photodetector arrangement for measuring the state of polarization of light
Inventor: AZZAM RASHEED M A
IPC: G01J4/04
Filed: 1987-01-23
Granted: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus and method for the measurement of at least one parameter of the state of polarization of a light beam is described.  The apparatus includes only a photodetector and no other optical elements.  The detector surface is partially specularly reflecting and intercepts the light beam at an oblique angle of incidence.  The absorbed fraction of incident radiation produces a corresponding electrical output signal that is detected and from which the at least of parameter of the state of polarization can be determined.  The detector may also be rotated to modulate the electrical output signal to determine the elliptic polarization of light except for handedness.  A two detector ellipsometer is disclosed wherein light reflected from one detector is absorbed by the second detector and the entire system is rotated.

Title: Electrical terminal connector
Inventor: BOEHM WILLIAM J
IPC: H01R4/36
Filed: 1987-06-18
Granted: 1992-03-31
Abstract: IMPROVED ELECTRICAL TERMINAL CONNECTOR               Abstract of the Disclosure An improved solderless electrical terminal connector includes a plurality of serrations or notches formed on its lower surface for improving the electrical and thermal contact between the connector and the surface onto which it is mounted.  The wire receiving portion of the connector includes a set screw for holding the wire securely in place in a body member.  The cross-sectional area of the body member in the direction of the wire is reduced so that it is less than the diameter of the set screw thereby to improve pullout characteristics.  The opening for the wire in the body member extends into a tang to form a stop to provide for ease of installation of the wire.  This placement of the wire will also reduce electrical resistance.  In an alternate embodi-ment, a spiral groove may be formed in the wire receiving opening to cut into the wire as it is clamped in place both to improve pullout characteristics and to lower the electrical resistance between the wire and the connector.

Abstract: A B S T R A C T            Improvements relating to the production of tea and the like bags The invention provides a machine for manufacturing and handling tea bags, wherein the tea bags are produced by laminating together two webs with individual quantities of tea therebetween.  Two rows of tea bags, formed in the webs, and the tea in the bags is biased upwardly of the webs.  This is followed by severing of the webs into two individual single tea bag row webs, and this is followed by transverse severing of the  web  to produce individual tea bags.  The tea bags are held into magazines so as to form two stacks therein and stacks of tea bags are moved laterally of the magazine into the inserting device and the inserting device places the two stacks of tea bags into a carton.  The two stacks of tea bags are placed together prior to insertion of the carton and extra conversion is given to the stacks to compensate for revising the tea.

Patent CA-1330287-C (CA)
Inventor: SOBEK ANDREW A
IPC: A01N25/10
Filed: 1988-01-21
Granted: 1994-06-21
Abstract: ABSTRACT     Various chemolithotrophic bacteria such as Thiobacillus ferrooxidans by direct or indirect mechanisms catalyze the oxidation of metal  sulfides and produce acid, i.e. sulfuric acid and soluble metal salts at a much faster rate than chemical oxidation. Elimination of such bacteria would inhibit the formation of the acid.  The natural production of such acids is particularly troublesome in mines e.g. coal mines, since acid water is produced which is damaging to the environment. An effective method of abating or eliminating such acid water production is to apply a bactericide such as a biodegradable organic surfactant which at low pH values are bactericides and hence inhibit the bacteria from catalyzing the metal sulfides. The affected acid water site can thus be treated with the surfactant which provides a temporary or short term result usually for a few months.  A long term solution, that is 1 year to several years, is provided through the use of a slow release composition of the present invention in which a heterogeneous matrix contains a thermoplastic domain and an organic surfactant domain. A suitable porosity is created when proper amounts of surfactant are utilized so that a long term slow release composition is formed. A method of making the heterogeneous matrix or slow release composition involves the dry blending of a thermoplastic compound and various processing aids, subsequently adding a bactericide thereto and mixing under shear and heat the resulting molten composition.  A suitable slow release article can be formed such as pellets.

Abstract: VISUAL ANALYTICAL TRACER AND METHOD FOR DETECTION AND QUANTITATIVE ANALYSIS FOR WATER TREATMENT CHEMICALS            Abstract of the Disclosure An inert water soluble dye is added to a concentrated water treatment composition.  This mixture is added to the water in a circulating water system such as a cooling tower.  The concentration of the dye and the concentration of the actives in the treatment composition are proportionate to each other. The concentration of the treatment composition in the water system can be determined by measuring the percentage of light absorbed by the dye in the water.      This can be determined by use of a colorimeter.          Fluorescein is the preferred dye.

Abstract: ABSTRACT OF THE DISCLOSURE      A self configuring memory for a computer system.          Memory is distributed between a central processor unit (CPU) memory and expansion memory boards that are selectively insertable into expansion slots of the computer system.  The CPU memory board and expansion memory boards each provide signals indicating the respective sizes of the memories.          Logic circuitry on each expansion memory board determines the cumulative amount of memory in the system.  This value is passed on to an adjacent expansion memory board  such that the logic circuitry on each board determines the range of addresses corresponding to the physical memory space resident on the board.  When an address within that range is accessed by the CPU, the logic circuitry generates an acknowledgement signal  hat is returned to the CPU.  In an intialization routine, the CPU tests the acknowledgement signal for each address in a sequence of addresses to determine the upper limit of the addressing range available in the computer system.
