Abstract: A telecommunication terminal block employs a housing (10) having a number of separate dielectrically isolated chamber (22) disposed therein. Service wires to be connected to a splice cable are inserted into a chamber through openings (12) in the housing and into a movable wire carrier member (24) disposed within the chamber. An actuator member (14) drives the carrier member (24) from a first position, at which the wires are inserted, to a second position where the wires engage a contact element (40) which electrically couples them to the splice cable. The carrier member (24) moves within the chamber (22) so as to allow an electrically insulating medium within the chamber to flow around the carrier and maintain a constant volume of the medium within the chamber. Loss of insulating medium is thereby avoided during connection and reconnection of the service wires allowing improved protection from environmental factors such as moisture, chemicals and other contaminants.

Abstract: A panel system is provided in which adjacent panels are removably joined at their edges. The system includes the following components: a pair of substantially identical clips, each of which is affixed to an edge of a panel, each clip including a base portion and a body portion extending upwardly from the base portion in a generally perpendicular disposition with respect to the base portion. At least two linear members extend in an inward direction away from the body portion away from the base. These members define slots which also extend parallel to thebase. The body further includes a substantially flat, outwardly facing portion on the side of the body opposite the members. Each of the panel edges defines a channelhaving flat walls which extend parallel to their respective panel. The channel walls extend from a channel bottom upwardly to the panel edge. The base of each clip is designed to be affixed to its respective channel at the bottom. The configuration and height of the clips are such that at least one of the linear members and at least one of the slots is disposed within the channel when the base is mounted in place, and at least one of the linear members and atleast one of the slots extends out of the channel beyond or above the edge of the panel. The flat, outwardly facing portion of the body of each clip extends in substantial contact with its adjacent channel wall when the clip is affixed in the channel. The clips and their associated panels can be mounted to one another by sliding the linear members of one of the clips into complementary slots in the other clips, with the channel walls preventing the two clips from being disengaged. Once it is desired to disassemble the panels they are vertically slid apart. Because the normal loading of a panel is not normally in that lengthwise direction, inadvertent dislodgement is highly unlikely.

Title: Electrically heated metal melt cell
Inventor: LE GRAS BRIAN W
IPC: F27B14/14
Filed: 1995-06-06
Granted: 1999-04-20
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.
