Title: Method of making a halogen incandescent lamp
Inventor: KIESEL ROLF
IPC: H01K3/26
Filed: 1997-06-11
Abstract: To provide a halogen incandescent bulb with controlled variation in wall thickness of the bulb, a bulb tube (20) first has a cup region (26) formed thereon.  The cup region, by radial application of force, for example by rollers (22), is constricted, and the constriction then pulled to form a small, closed projecting tip (19).  Mold jaws (27) then mold the shape of the bulb; the mold jaws are formed with a cavity (29') to receive the projecting tip (19) which, then, has the end cut off to provide an attachment cannula (30) for the pumping tube (32). The pumping tube is melted on the nipple (29) of the cup (26) of the bulb.  A filament mount (8) with filaments (9) is then introduced, and pinch jaws (35) pinch-seal the filament mount in the bulb and finish-shape the bulb.  The bulb can then be flushed, evacuated, and filled with the requisite halogen containing fill through the pumping tube (32), which then is tipped off.

Abstract: In a brush holder device, in which an action-side end portion 22a of a torsion spring 22 is engaged with a torsion spring engaging groove 25 recessedly provided in an end surface of the brush 24 on the side opposite to a commutator 23, so that the elastic force of the torsion spring presses the brush against the commutator 23, a first inclined surface 26 is formed in the end surface of the brush 24 so as to incline at an angle of 15°  relative to a plane perpendicular to the axis of the brush, and second inclined surface 27 is formed in the engaging groove 25, being superposed on the first inclined surface 26.  Further, a pigtail 28 is connected to the brush at an offset point relative to the engaging groove 25.

Title: Duplex procedure for the production of metals and metal alloys from oxidic metal ores
Inventor: DRY RODNEY JAMES
IPC: C21B13/02
Filed: 1996-11-04
Abstract: The production of highly metallised feed, an intermediate product produced solely by gaseous reductants in two stage reduction processes of that kind, encounters sticking problems, which interfere with continuous processing and productivity. This problem has been overcome by exploiting a high volatile carbonaceous material, such as coal, as the reducing agent for the (partially reduced) oxide ore starting material in the solid state prereduction stage of a duplex process, in which the final stage consists of smelting, to produce the final metal (alloy).  Intermediate products of the first stage are char from the coal, which avoids the sticking problem, partially reduced ore and CO and H2, which participate in the prereduction. The process has particular application to iron ores, such as haematite and magnetite and similar derivatives, namely, chromite and oxidic nickel ores. The process may be extended to a triplex, which includes drying, preheating and partial reduction in the first stage, followed by further partial reduction and finally the smelting step. Plant for the process may consist of a shaft furnace or fluidised bed for the prereduction sequence, preferably the latter.  For the triplex process, two associated fluidised beds (3, 5) are preferred. Any suitable furnace (7) may be used for smelting, as long as it is equipped for the injection of partially reduced ore, char and fluxes, hot air lancing, off gas and the tapping of molten metal and slag. The final stage of solid state reduction takes place at a temperature of at least 550 °C, preferably 750-900 °C. At least 50 % of metallisation is essential for satisfactory processing, preferably at least 80 %.
Patent CA-2237003-A1 (CA)
Inventor: SORIANO NINO
IPC: A47J37/07
Filed: 1998-06-10
Abstract: This is a component used to minimize the amount of oils that drip into the element of the barbeque and the coals or lava rocks, therefore allowing even heat thoughout with little or no induced flame in any one particular area. The idea is to allow heat to evenly cook the food and to provide a path for the fluids to travel without dripping onto the hot element, coals, or rocks. Another benefit to this product is to have an oil tray to store all the extra juices. The cooking bed is parallel to the heat element with the heat vents, and the juice channels are set at an approximate 8 degree angle in order for the juices to move to the oil tray. This product, in my mind, should be recommended by code in order to limit the chances of an uncontrollable fire. The grills are set-up as interlocking so that they can be easily connected in pairs or more.

Patent CA-2238514-A1 (CA)
Inventor: NAKAJIMA TOSHIKATSU
IPC: H04L12/70
Filed: 1998-05-25
Abstract: A telephone communication method capable of promoting the efficient use of the limited number of IP (Internet Protocol) addresses is disclosed. When a call is originated on a first telephone terminal, a first gateway accommodating the terminal accesses a DNS (Domain Name System) server via a UDP (User Datagram Protocol) channel of Internet or Intranet. The first gateway inquires the DNS server of the IP address of a second gateway accommodating a telephone terminal to be called, using an office number assigned to the second telephone terminal as a host name. The DNS server returns the IP address of the second gateway to the first gateway via the UDP channel. In response, the first gateway selects its own IP address for speech transfer and sends a call connection request to the second gateway on a TCP (Transmission Control Protocol) channel of Internet. On receiving the request, the second gateway determines whether or not the second telephone terminal is busy, and selects the IP address for speech transfer if it is idle. The IP address selected is returned to the first gateway in the form of a response message. As a result, a connection is set up between the two telephone terminals.
