METHOD FOR PRODUCING A HEAT TRANSFER WALL FOR VAPORIZING LIQUIDS
BREWING
Heikichi Kuwahara, Kenji Takahashi, Takehiko Yanagida, Wataru Nakayama, Shigeo Sugimoto, Yoshihik Nakayama, Hiromichi Yoshida, Kiyoshi Oizumi, Toshi Sasaki, Shigeho Fukuda, Ibaraki, Japan assigned to Hitachi Ltd; Hitachi Cable Ltd A method of producing a heat transfer wall, including a plurality of minute tunnels parallelly extending and spaced a minuscule distance from each other under an outer surface of the wall in contact with liquid, and a plurality of tiny hole portions formed at the outer surface of the wall above the tunnels and located at regular intervals along the tunnels to maintain same in communication with the outside. Each hole portion includes a projection located in the hole portion including a hole itself and extending from the vicinity of the hole portion into the hole portion in a manner to traverse same, so that a flow of liquid into the tunnels and a flow of vapor out of the tunnels can be optimally regulated by the projections to enable the heat transfer wall to exhibit a high heat transfer performance.
Noel R Wilkinson, Burton on Trent, United Kingdom assigned to Robert Morton DG Limited An improved brewing unit in which energy is saved by providing a mash tun, hot water tank and kettle in a single unit, by partially enclosing the mash tun with the tank and if necessary preheating the water supply to the tank by using the heat from wort coolers provided between the unit and fermentation tank; further improvements are provided by constructing the kettle as a combined kettle and whirlpool in a single chamber having a circular wall and a tangential inlet to the wall, a pump and wort boiler being in circuit with the kettle so that wort is continuously circulated through the boiler and tangential inlet to the kettle while the worts are boiled. The combined kettle and whirlpool saves space and enables the process of brewing to be shortened with resultant savings in both energy and brewing time.

4653268 REGENERATIVE GAS TURBINE CYCLE Hirom Nakamura, Takehiko Takahashi, Norio Narazaki, Kazuo Yamamoto, Norio Sayama, Chiba, Japan assigned to Mitsubishi Gas Chemical Co Inc In a regenerative gas turbine cycle in which heat recovery is carded out by multi=phase and multicomponent mixture of compressed air/liquid phase water/steam (hereinafter referred to as MPC mixture), said mixture being obtained by injection of liquid phase water (hereinafter referred to simply as water) into a part of or the whole of compressed gas using air or air based gas (hereinafter referred to as air) as a combustion supporting/working medium gas; the improvement comprising (a) intercooling of said compressor, and/or Co) precooling of the compressed air for producing the MPC mixture by a part of the MPC mixture. H.L$. ?/S--F
Warren W Quinlisk, James A Fernholz assigned to L B White Company Inc A heat exchanger (10) for transferring heat between intake air and exhaust air is disclosed. The heat exchanger (10) includes a plurality of ducts (11) having open first and second ends (1 lc and 1ld). The ducts (11) are connected in a vertical space relationship to one another defining therewith two sets of channels. A first set of channels (1 la) being inside the ducts (11) and a second set of channels (1 lb) being between the ducts (11). Intake air passes through the first set of channels (1 la) and exhaust air passes through the second set of channels (1 lb). The air flow in the second set of channels (1 lb) is confined. The heat exchanger has a releasably attached bottom (24), whereby when the bottom (24) is released, there is ready access to clean said second set of channels (1 lb) between the ducts (11). Also, the intake air and exhaust air enter and an exit through their respective sets of channels without mixing. The heat exchanger (10) has an inlet (18a) and outlet (19a) for fresh air in the first set of channels (1 la) and an inlet (30a) and outlet (34a) for exhaust air in the second set of channels (I ld).
