Patent CA-2164080-A1 (CA)
Inventor: MUNAKATA TAKEO
IPC: H01B5/10
Filed: 1995-11-29
Abstract: An overhead cable provided with a plurality of segment strands of a sector-shaped cross-section twisted at the outermost layer and having grooves of a substantially arc-shaped cross-section at the surface at the adjoining portions of the segment strands. Also, a low sag, low wind load cable provided with tension-bearing cores comprised of strands having a linear expansion coefficient of -6 × 10 -6 to 6 × 10 -6/°C and an elastic modulus of 100 to 600 PGa and with a plurality of sector-shaped cross-section segment strands twisted around the outermost circumference of the cable including the tension-bearing cores comprised of a super-high-heat resisting aluminum alloy or extra-high heat resisting aluminum alloy, grooves of a substantially arc-shaped cross-section being provided at the surface at adjoining portions of the twisted segment strands. This enables the wind load to be reduced. Further, a low wind load cable can be easily fabricated at a low cost. In addition, by using invar strands for the cores and using segment strands of a super-high heat resisting aluminum alloy or extra-high heat resisting aluminum alloy at the outermost layer, the sag at high temperatures can be greatly suppressed. Accordingly, even the amount of the sideways swinging caused when the overhead cable is struck by a strong wind from the lateral direction can be greatly suppressed together with the low wind load construction.

Title: Method for the utilization of residual materials in the production of cement
Inventor: MEININGER SIEGFRIED DIPL-ING
IPC: C01B17/74
Filed: 1996-02-13
Abstract: Within the known Müller-Kühne process and a corresponding installation, a utilization of a great variety of residual materials can be achieved with optimum process control, both in regard to the production of a raw powder and the fuel, whereby this is made possible in particular in that the raw powder components and the fuel components also are, with respect to the residual materials being used, stored separately, conditioned, and then mixed according to the formulation under strict monitoring. The glue gas is used for preheating the raw powder by adding the cold raw powder to it. This simultaneously removes sticky components from the flue gas. The raw powder preheated in this manner, and also the raw powder or dust recovered in subsequent dedusters are returned to the rotary drum kiln, whereby the solid and other fuels are used and burned with a mutually supportive flame at the opposite end of the rotary drum kiln.

Title: Thin film transistor with reduced channel length for liquid crystal displays
Inventor: DEN BOER WILLEM
IPC: H01L29/786
Filed: 1996-05-15
Abstract: A liquid crystal display including an array of thin film transistors. Each thin film device in the array includes gate, source and drain electrodes. At least one of the source and drain electrodes include first and second metal layers offset with respect to one another so as to reduce the channel length of the transistors.          Because of the reduced TFT channel length, the TFT channel width can also be reduced while maintaining the same ON current. Thus, the gate-source capacitance is reduced which in turn reduces pixel flickering and image retention and improves gray level uniformity. The first and second source-drain metal layers are of different materials so that the etchant for the second metal does not etch the first metal layer deposited. The TFT may be either a linear TFT or a ring-shaped TFT according to different embodiments of this invention.

Abstract: Process and Apparatus providing a fully automated magnesium melt system. Raw magnesium ingots are moved through a preheater chamber where they are thoroughly dried by being controllably heated to a temperature in the range of 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 i.e. run mode (production) or idle mode (non-production, weekend) via the operator computer interface. There are two heating 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 a 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.

Title: Multi-functional plastic double wall panel & drainage system
Inventor: GRAUL RUSSELL CHARLES
IPC: E02D31/02
Filed: 1996-08-15
Abstract: A plastic double wall panel is presented as a multi-functional purpose panel that can be laminated to any rigid or semi-rigid substrate to provide protection! waterproofing, bugproofing, drainage, solar heating, and/or an air transfer system, as well as offer a smooth surface for finishing or signage. The invention provides a component comprising of a plastic double wall sheeting that is an extrusion of 2 parallel walls which are connected by numerous flutes or channels, along its length, in a perpendicular or triangular pattern to form a rigid single panel. One side of the double wall panel may be slotted or perforated to create a drainage system. This allows liquid to pass through the perforated wall and drain along the flutes. The other side that is not perforated acts as a waterproof barrier or membrane. Also a cloth or material which allows liquid to pass through but not particles, may be attached to the perforated side to form a filter system. The plastic double wall panel can be laminated to any type of rigid or semi-rigid foam, such as extruded, expanded, polyurethane, or rigid polyisocyanurate foam (which is bonded directly during manufacture of the foam), to form an insulated protected panel, and/or part of an insulating concrete system. The length, width and thickness of the laminated foam panels can be varied to conform to different size specifications. The foam side of the concrete forming panels, facing the concrete, can be grooved along its length (vertical). This allows the cement to bond completely to the foam, eliminating the need for fasteners and creating an effective moisture barrier. the edges of the foam may have an interlocking design so as to form a continuous wall. The plastic double wall acts as a crush zone to protect the foam during backfill of a below ground wall as well as seals, waterproofs, and bugproofs the wall along with providing drainage, a solar heating, and/or an air transfer system. The plastic double wall panel also uses the inner airspace for added insulation affect.

Title: Spectacles using variable focal length lenses which have an arbitrarily shaped periphery
Inventor: EPSTEIN SAUL
IPC: G02C7/08
Filed: 1995-04-10
Abstract: A variable focal length lens whose peripheral shape can be arbitrarily specified, for use in spectacles, which includes a rigid lens (12) to provide the wearer's distance correction, and a liquid-filled lens bounded by a stretched distensible elastomeric membrane (15) to provide a variable near addition. The liquid (21), which has a fixed volume, is stored in the field of view between the elastomeric membrane and the rigid lens. Variation of the optical power of the liquid filled lens is achieved by displacement of a membrane support to which the outer periphery of the stretched elastomeric membrane is attached. The shape of the distended membrane is kept substantially spherical, despite the circumference of the membrane being non-circular. This is accomplished by supporting the membrane on a transparent spacing member which has substantially the same refractive index as the liquid and which includes a circular opening which defines the free area of the membrane. A pair of spectacles is comprised of two variable focal length lenses mounted to a frame with an actuator for adjusting their focal lengths mounted on the frame between the lenses.
