Title: A recognition apparatus and method for security systems
Inventor: GRAHAM DAVID
IPC: G07C9/00
Filed: 1991-10-11
Abstract: A method of authenticating input data including user data and pin code data for an access control system. The method includes the steps of receiving the user data and the pin code data from a keyboard and/or a card reader (II), combining an offset data with the user data (13), making a modulo adjustment of said offset user data, obtaining one or more variables from the offset user data (14), calculating a matrix index (15) by bringing certain variables into a predetermined equation, determining a constant (16) from a matrix by the matrix index and comparing (17) the constant with a corresponding digit value of the pin code data. If the constant matches the digit value, a validation signal is generated and the next constant is obtained from the matrix by the next matrix index obtained by use of a predetermined second equation so that next digit value of the pin code data is compared with this constant. This procedure continues until all subsequent digits of the pin code data are checked to determine whether the input data entered into the access control system is true or not. If the data is true, the access is granted.

Abstract: A component for use in a multi-lobular drive system of the type having coaxial, engageable female and male members.          One of the members has threads formed thereon defining a rotational direction.  The female component includes a multi-lobular recess (53) and the male component includes a multi-lobular projection engageable with the recess (53).          The multi-lobular recess (53) and projection each define alternating, interengageable flutes and lobes in which the flutes and lobes on the female member engage the corresponding lobes and flutes of the male member.  The flutes and lobes on one of the members has drive walls and trailing walls which are positioned substantially parallel to the central axis.  The other of the members has drive walls (32,64) and tapered trailing walls (34,66).  Each of the tapered trailing walls (34,66) forms an angle relative to the associated drive walls (32,64).  The tapered trailing wall (34,66) provides a wedging engagement with the corresponding trailing wall of the other member when the male and female members are interengaged.

Title: Method of geochemical prospecting
Inventor: CLARK JOHN R
IPC: C22B3/18
Filed: 1992-10-13
Abstract: A method of geochemical prospecting where samples of soil, sediment and rock in a geological area are collected and each sample is contacted with a leach solution of water, glucose and glucose oxidase. The oxidase acts upon the glucose to produce gluconic acid and hydrogen peroxide. The leach solution reacts with manganese dioxide carrying trace metal elements and compounds in the samples to produce a leach reaction solution.      The leach reaction solution and the residue of the said sample are separated, and the leach reaction solution is analyzed to determine the trace metal content present. From the analysis, the mineral content of the geological area is predicted. The leach solution may also contain ascorbic acid, catalase, galactose oxidase and a salt such as water soluble metal cyanides and water soluble metal halides.

Title: Device for enriching water with co- gas in order to generate carbonated water
Inventor: NOTAR ROBERT
IPC: B01F15/00
Filed: 1993-08-25
Abstract: Apparatus including a circulating pump inside a carbonator tank which blends CO2 with still water and which is started and stopped for predetermined time periods in repetitive cycles having an on/off ratio ranging between 1:10 and 1:20. A timing circuit controls the operating and non operating times of the circulating pump so that sufficient carbonation of the water with CO2 gas is achieved along with the formation of an ice bank on the cooled wall of the storage tank. During intervening periods when the circulating pump is not operating, the carbonated water arranges itself in layers according to its density so that the relatively warmer water sinks while the colder water together with any ice particles or small pieces of ice floating therein join together, becoming fixed to the ice bank in the upper portion of the carbonator. During the next operating cycle of the circulating pump, these particles are frozen together and become relatively harmless to the extent that the shutoff valve and output carbonated water line remains unobstructed. Whenever carbonated water is removed from the storage tank or fresh water is supplied to the storage tank, the circulating pump is again started for an additional on-period time interval which is greater than the normal on-period.

IPC: H01H85/36
Filed: 1992-10-02
Abstract: An electrical interruption device is disclosed in which an overcurrent protective device is provided to interrupt electric current flow on a sustained overcurrent current occurring.  The overcurrent protective device is characterized by a plunger which is held in tension against the force of a spring by a low temperature solder, and further in which a sleeve of insulating material, such as silicone, is provided about the plunger.  Preferably, the overcurrent protective device includes a housing, with the plunger disposed in the housing and having one end extending therefrom to provide electric communication with the remainder of the electric circuit.  The sleeve of insulating material preferably being located about the end of the plunger which extends from the housing.  On a predetermined condition causing the solder to melt, the plunger is released and under the force of the spring is moved to a position retracted within the sleeve, interrupting the current flow.  Advantageously, the overcurrent protective device may be used together with pulverulent arc quenching material.  The sleeve acts to isolate the pulverulent arc quenching material from the plunger and prevent its interference with the plunger as it is moved under the force of the spring.
