Abstract: A counterflow heat exchanger has a pair of disklike end plates between which there are disposed a multiplicity of disklike heat transfer walls. The heat transfer walls have peripheral flanges which are fluid-tightly joined to each other to provide spaces between the walls. There are a first and a second pair of spaced openings defined through each heat transfer wall for the passage of a first and a second fluid respectively therethrough. Each heat transfer wall is additionally fluid-tightly joined to an adjacent heat transfer wall on one side thereof at their edges bounding the first pairs of openings, and to another adjacent heat transfer wall on another side thereof at their edges bounding the second pairs of openings, so that two sets of flow paths for the two fluids are formed alternately by and between the heat transfer walls. The two pairs of openings in each heat transfer wall are situated adjacent the peripheral flange thereof for uniform fluid distribution throughout each flow path.

Abstract: A pair of heat exchangers of generally cylindrical shape are coaxially coupled to the opposite ends of a cylindrical air-water separator. Each heat exchanger has a stack of heat transfer disks brazed together to define two alternating sets of intercommunicating flow paths. The first set of flow paths of the first heat exchanger receives high-temperature, high-humidity air under pressure, which is precooled by low-temperature, low-humidity air flowing to the second set of flow paths from the air-water separator. The precooled high-humidity air is directed through an internal passageway in the separator into the second heat exchanger, in which the air is cooled by heat exchange with a coolant. The cooled high-humidity air is then directed into the separator for reduction of the moisture. The low-temperature, low-humidity air is then afterheated by precooling the incoming high-temperature, high-humidity air in the first heat exchanger, for subsequent delivery to a load.

Abstract: There is disclosed a vacuum-pressure regulating device which is attached to a vacuum system in connection with a vacuum pump so that it serves to ensure a constant vacuum pressure in the vacuum system and then to supply vacuum pressure from the vacuum system, after reduced to the required extent, to a desired space. The vacuum-pressure supply device of the present invention is suitable for adjusting vacuum in vacuum systems for milking cows.

Abstract: A milking machine detects a flow rate of milk during milking and integrates by a completion timer the time when the detected flow rate is smaller than a reference flow rate near an end of the milking, the integrated time being displayed graphically. The reference flow rate is corrected by a specific resistance of milk. The specific resistance is obtained by selecting a minimum resistance value from resistance values of milk which are actually measured during a predetermined time interval starting from a time after milking begins when a flow rate of milk measured on the basis of a predetermined standard resistance value reaches a predetermined value.

Abstract: A milk-claw for collecting milk sucked from cow's teats through teat cup liners and sending it to a vacuum milking machine, in which the horizontal sections of the collecting chamber in the milk-claw are formed polygonally to prevent the milk which flows into the milk collecting chamber through liner nipples from forming a whirlpool, and the vertical section of the collecting chamber is formed polygonally to prevent milk directed forcibly through a liner nipple into the milk collecting chamber from flowing backward through another liner nipple.

Abstract: An infrared ray generator includes a housing of heat resisting refractory material, the housing forming a first opening facing in a desired heating direction. A number of heat resistant fiber mesh screens cover the first opening and, together with the housing, form a combustion chamber. A burner extends through a second opening in the housing to direct a combustion flame into the combustion chamber so that the mesh screens are brought to red heat. Gaseous substances, which originate from the burner combustion flame, are then burned upon contacting the mesh screens, so that these substances do not pass to the outside air. The mesh screens also serve to suppress noise developed within the combustion chamber.

Abstract: An improved nozzle spray type burner including a combustion chamber, a housing having an exhaust passage coupled to the combustion chamber, a fan mounted in the housing for directing air through the exhaust passage to the combustion chamber and a fuel spray nozzle in the exhaust passage for spraying fuel into the flow of air in the exhaust passage. The improvement includes a first mechanism associated with the fan to control the flow rate of air in the exhaust passage, and a second mechanism associated with the nozzle for controlling the amount of fuel sprayed from the nozzle. The first and second mechanisms are arranged to cooperate to control the degree of combustion of the fuel with the air in the combustion chamber.

Abstract: A device for detecting and signalling the end of a milking period includes a sensor for detecting variations of the quantity of milk flowing in a milkline connected to a test cup, and providing a corresponding output signal. Circuitry is provided for detecting the output signal of the sensor, and for actuating a signalling device such as an alarm buzzer when the flow of milk in the milk line remains below a certain level over a given period of time.

Abstract: An infrared heater includes a combustion chamber having a radiator with a surface arranged to direct radiant heat in a forward heating direction. A fan has an outlet opening which is located to direct a flow of air above the radiating surface, thereby deflecting convective air heated by the combustion chamber in the forward direction. The fan is mounted above and on the rear side of the chamber so that it is out of the influence of radiant and convective heat developed by the chamber. A motor which drives the fan is mounted at one end of the fan so that the motor is also not affected by the radiant and convective heat.

Abstract: A milking machine tap assembly for connecting a teat cup unit with a vacuum pipe and a milk pipe extending within the vacuum pipe. A tap box unit is provided which has a housing with a window opening in its side wall, and two axially aligned connecting tubes at opposite ends of the housing to connect with confronting sections of the vacuum pipe. A tubular milk tap body within the housing has its ends arranged to connect with confronting sections of the milk pipe, the tap body also having a first port through its side wall to enable the teat cup unit to communicate with the milk pipe through the tap body. A tap frame is fixed to the housing over the window opening to position the first port. An air packing is mounted on the frame and cooperates therewith to form a second port which enables the teat cup unit to communicate with the vacuum pipe through the housing interior. A gate is slidably mounted to the frame for simultaneously closing the first and second ports.
