Permanent magnetic coupling transmission, braking or load device with cooling and lubricating device

The invention relates to a permanent magnetic coupling transmission, braking or load device with a cooling and lubricating device. The permanent magnetic coupling transmission, braking or load device is in a structure of a rotor disc, a rotating cylinder or in a combined/composite structure of the rotor disc and the rotating cylinder. The permanent magnetic coupling transmission, braking or load device consists of at least one group of axial magnetic field or/and radial magnetic field permanent magnetic coupling modules, at least one pair of a driving rotor disc/rotating cylinder coupling mechanism and a driving shaft coupling mechanism, at least one pair of a driven rotor disc/rotating cylinder coupling mechanism and a driven shaft coupling mechanism, one pair of air-gap space and coupling area adjusting mechanisms, at least one set of coolant cooling devices, at least one set of lubricating devices, at least one pair of integrated assembling mechanisms facilitating integration of system structure and a shell. The permanent magnetic coupling transmission, braking or load device is suitable for the technical fields such as transmission, speed regulation of transmission shaft and load, braking, rotating load, energy conservation and emission reduction, disconnection/connection power and the like. The invention is used for designing a technical scheme of a permanent magnetic coupling device, a speed regulation coupler device, automatic speed changing device, a brake device, a load/loading device, a centrifugal load speed regulation device or an engaging-disengaging device.

Semi-frozen food product producing machine

The present invention includes a dual purpose carbonator/blending bottle connected to a source of beverage syrup, a source of potable water and to a source of pressurized carbon dioxide gas. The dual purpose bottle is retained within an ice bank water bath tank. A pair of ratio valves provide for metering the water and syrup at a desired ratio. The mixed beverage first flows through a serpentine coil, also located in water bath, and then flow into the dual purpose bottle. A refrigeration system provides for cooling an evaporator located in the water tank for forming the ice bank thereon. The carbonated beverage then flows from the bottle into a freeze cylinder. The freeze cylinder also includes a further evaporator coiled around an exterior perimeter thereof. The freeze cylinder evaporator is connected to and cooled by the same refrigeration system that cools the evaporator in the water bath tank. A scraping mechanism within the cylinder provides for scraping frozen beverage from the inner surface of the cylinder. A control mechanism provides for controlling the refrigeration system and the cooling of both evaporators. The beverage is therefore pre-cooled to a temperature just above its freezing point before delivery to the freeze cylinder. Thus, less cooling power is needed to reduce the beverage to a frozen state. The present invention utilizes a method of controlling the operation of the refrigeration system and the cooling of both evaporators thereof. The control system provides for directing refrigerant to one or the other of the evaporators as is most efficient so as to avoid short cycling or pressure build up. The present invention uses a control strategy that can more accurately maintain a pre-selected temperature differential between the inlet and outlet temperatures of the evaporators. The control algorithm utilizes a proportional integral differential control approach that safely permits a much narrower temperature difference so that a greater length of each freeze cylinder evaporator can be utilized for efficient heat transfer cooling.

Ka-band tilt-structure active phased array antenna

The invention provides a Ka-band tilt-structure active phased array antenna, so as to provide an active phased array antenna which is high in integration density and can improve maintainability and interchangeability. According to the technical scheme, one path of RF signals transmitted by a transmitting signal processing terminal are transmitted to a power distribution/synthesis network (5) via a signal interface and a radio frequency interface to be divided into M paths of signals; according to information of an azimuth angle and a pitch angle of the phased array antenna provided by the transmitting signal processing terminal in real time, a beam controller (4) calculates and obtains beam pointing of the phased array antenna in real time through an FPGA; the beam pointing of the phased array antenna is converted into phase data needed by each array element under control of the beam controller (4); the data are transmitted to tilt-type TR assembly sub array modules in N channels respectively via a high and low-frequency interconnected multi-core high and low-frequency socket, and under control of the beam controller, M*N paths of signals are transmitted to an antenna array, and thus signal transmission is completed, and synchronous electric control scanning of beams transmitted by the phased array antenna is realized.
