Granted: 1997-02-25
Abstract: An overflow controller detects and prevents the introduction of supply fluid into a receptacle beyond a predetermined level.  A vertical overflow chamber is in communication with the receptacle and contains a float which is buoyed by fluid entering the overflow chamber when the fluid level in the receptacle increases above the predetermined level.  The float preferably interacts with a proximity detector that senses the float when it moves sufficiently close.  As the float rises towards the sensor, the sensor is activated to produce an output which is received by a fluid controller.  The controller then prevents any supply fluid from being added to the receptacle.

Title: Apparatus and method for providing synchronization of base-stations in a communication system
Inventor: WALSH WILLIAM J
IPC: H04W92/00
Filed: 1993-09-22
Granted: 2000-11-21
Abstract: A communication system (105) utilizes the global positioning system (GPS) to maintain a high degree of accuracy of synchronization of base-stations (115-116). When the GPS signal (106, 107, or 108) is absent, the communication system (105) employs an alternate signal (110-113), such as a WWVB, LORAN-C, and MSF  signal, to provide redundant synchronization of the base-stations (115-116). To achieve the degree of synchronization accuracy provided by the GPS signal (106-108), the communication system (105) characterizes the alternate signal (110-113) by utilizing the GPS  signal (106-108) when the GPS signal (106-108) is present. When the GPS signal (106-108) is absent, the characterized alternate signal is then employed such that synchronization of the base-stations (115-l16) is transparent to the base-stations (115, 116).  Use of the GPS signal (106-108) to characterize the alternate signal (110-113) also allows the characterized alternate signal to provide the same degree of accuracy as that of the GPS signal (106-108).

Title: Controlled magnesium melt process, system and components therefor
Inventor: LE GRAS BRIAN W
IPC: F27B14/16
Filed: 1995-06-06
Granted: 1996-07-23
Abstract: Process and Apparatus for a fully automated magnesium melt system. Raw magnesium ingots are moved through a preheater chamber heated by radiant heat panels where they are thoroughly dried by being controllably heated to a temperature range of about 150°C to 250°C preferably 200°C to 225°C before they are introduced into a melt cell also referred to as a furnace. The ingots, are monitored for temperature by an infra red temperature sensor or a direct contact type thermocouple and this determines whether the ingot is ready to be charged into the furnace. A furnace metal level probe monitors the metal level and a control unit causes ingot charging as determined by a process level set point or temperature overshoot. The melt cell, or furnace uses a closed loop P.I.D. (Proportional Integral Derivative) equation that is enhanced in a PLC (Programmable logic controller) program by introducing variables that are interactive with an ingot being charged to the furnace metal bath, the die cast machine being started and placed into automatic cycle or semi-auto, and also by which furnace control mode the operator has selected via the operator computer interface.      The two furnace control modes are run mode (production) and idle mode (non-production, weekend). There are two zones of heat in the furnace with each zone supplied by its own 3 phase zero cross fired silicon controlled rectifier firing boards which are gated by A 4-20mA gating signal.      This controls how much the SCR's are allowed to conduct.      The amount of error between the metal bath set point and the actual metal bath temperature automatically determines how much of the 4-20mA gating signal is required to maintain the predetermined metal bath temperature. Liquid magnesium is transferred from the furnace to the die cast machine shot sleeve pour hole by a siphon transfer tube which has two sets of electrical heating elements. The melt cell upon receiving a request from the die cast machine for material will, as long as all conditions are met in the melt cell PLC program, allow the transfer tube to lower to the die cast machine pour hole. The transfer tube valve then opens for the length of time set by the operator via the operator computer interface. Providing all safety conditions are met and sensor activated for signal to PLC. Upon completion the valve closes and the transfer tube raises to its home position to be ready for the next cycle. The signal to the die cast machine that the pour is complete is given as soon as the valve closes and the tube begins to raise. Interactive communication between the die cast machine computer, a control computer and other monitoring or remotely located computers provide complete process control and information. This provides total control of the temperature of the magnesium at all times, for safe operational quality and cost effective casting.

Granted: 1999-12-07
Abstract: A caulk dispenser device for use with conventional caulking cartridges and powered by expanding refrigerant liquid is disclosed.  Expanding gases are released into a chamber defined in part by a housing and in part by the caulk cartridge, the plug or piston within the cartridge forming a boundary of the chamber.  Discharge of the gas directly against the piston is avoided by the interposition of a deflector surface within the housing reducing the tendency of the caulk to increase in viscosity and bond to the walls of the cartridge or to tilt relative to the cartridge.  The propellant liquid-gas material incorporates an increment (e.g. 5%) of perflurocarbon or like compound liquid at ambient temperatures which minimizes the cooling effect resulting from discharge of the gas.  Preferably, the device is fabricated of material having a low thermal conductivity such as polymeric material to thereby reduce the cooling effect on the canister of propellant with resultant loss of pressure.
