Patent ID-24295-A (ID)
Inventor: GATHJE JOHN C
IPC: C01G1/00
Filed: 1997-10-23
Abstract: Provided is a method for processing a gold-bearing sulfide ore which involves maintaining the ore in a substantially oxygen free environment, preferably beginning with comminution of the ore and ending when a desired final concentrate, enriched in sulfide minerals, is obtained by flotation. In one embodiment, nitrogen gas is used to substantially prevent contact between the ore and air during comminution of the ore and during flotation operations. It is believed that oxygen gas present in air detrimentally affects the recovery of sulfide minerals in a flotation concentrate through surface oxidation of sulfide mineral particles. The use of a gas such as nitrogen can significantly reduce the potential for such surface oxidation. Additionally, gases separated from an oxygen plant may be beneficially used, with an oxygen gas stream being used, for example, for pressure oxidation of sulfide mineral materials, and with a nitrogen gas stream being used in comminution and/or flotation operations, resulting in advantageous use of a nitrogen gas by-product stream which has previously been vented to the atmosphere as waste.

Abstract: PURPOSE:To prevent the scatter of a toner image and the deviation of the image, etc., and to miniaturize a device by heating a conductive member and simultaneously transferring and fixing the toner image in a transfer device having the conductive member which transfers the toner image on a photosensitive drum on a transfer body. CONSTITUTION:The toner image on the photosensitive drum 1 is transferred on the transfer sheet 4 whose leading edge is seized by a gripper 5. At such a time, a voltage whose polarity is opposite to that of toner is impressed on a transfer roller 2 and also the heat of a fixing roller 3 heated by a heater 7 is conducted to said roller 2. Therefore, the heat of the roller 2 reaches the toner image on the drum 1 through the transfer material 4 and only surface contacting with the transfer material 4 becomes in a melted state. The toner image is provisionally fixed on the transfer body 4 and, thereafter, it is completely fixed by the fixing roller 3.

Title: Cross flow fan
Inventor: SUGIO TAKASHI
IPC: F04D17/04
Filed: 1990-01-11
Abstract: PURPOSE:To suppress the occurrence of a wide-band noise and obtain cross flow fan which is silent when operated by providing grooves along the rotation direction on the inner periphery of the negative pressure side face of each blade. CONSTITUTION:A cross flow fan has the characteristic that an air stream passes through the blade train of an impeller 1 twice. The air stream is reversed at the same blade 5 when it passes through the suction section 7 and discharge section 8 of the cross flow fan. The discharge section 8 generates a high wide- band noise S in general. When the air stream from the upstream shown by an arrow A passes through the discharge section 8 and crosses the blade 5, it collides with the front edge F of the blade 5 and generates a pressure pulsation on the surface of the blade 5 mainly to cause the wide-band noise S generated on the negative-pressure side face 5a. The pressure pulsation is mitigated and absorbed by the grooves 6 on the face of the blade 5, and the noise value can be reduced.
