Described is a fixing arrangement for releasably fixing an air conditioning module to the roof of a vehicle such as a rail vehicle. The module has opposite side surfaces from which first fixing projections project. The vehicle roof supports positioning rail members in mutually parallel relationship at a spacing from each other corresponding to the spacing between the side surfaces of the module. The positioning rail members have upwardly open first openings. Second fixing projections project from the positioning rail members at the outside thereof laterally beside the first openings. Locking rail members are adapted to co-operate with the positioning rail members, for which purpose the locking rail members have slots operatively associated with the second fixing projections and second upwardly open openings which are associated with the first openings and which have a portion extending in the longitudinal direction of the respective locking rail member for lockingly receiving the first projections on the positioning rail members.

A cable positioning arrangement comprises a flexible member, such as an elastic band or cord, extending between two structures. The flexible member is associated with a hole through which a cable passes thereby positioning the cable relative to the structures.

The invention discloses a continuous grinding mechanism based on grinding belt surface self-growth. The continuous grinding mechanism based on the grinding belt surface self-growth comprises a grinding belt, a water tank, an abrasive particle injector head, a UV light lamp tube, a workpiece installing head, a double-directional cylinder and a base station; the water tank is filled with UV light solidified coatings, an idler wheel is installed in the water tank, two idler wheels which are higher than the water tank are installed on two sides of the water tank, when the grinding belt moves, the grinding belt firstly enters the water tank, after the grinding belt moves out of the water tank and moves to be horizontal, the surface of the grinding belt is covered with the UV light solidified coatings, and grinding belt surface self-growth is conducted; the abrasive particle injector head is installed above the horizontal position of the grinding belt, the UV light lamp tube is installed on the back face of the abrasive particle injector head, and the height of the workpiece installing head can be adjusted through the double-directional cylinder, the height can be maintained until workpiece machining is completed. By means of the structure, restoration of the grinding belt is simple, fast and convenient, dismounting of the grinding belt is not needed, the restoration of the grinding belt and the workpiece machining can be conducted synchronously, and the surface of the restored grinding belt is flatter and neater.

The invention discloses a method for prolonging life of pump shells and blades by carrying out laser strengthening, which relates to the technical fields of machinery manufacturing and laser processing application. The method adequately combines the characteristics of laser cladding with laser shock strengthening, i.e., the method comprises the steps of performing laser cladding repair on micro-cracks at first, and then performing laser shock strengthening treatment on a cladding layer, thus effectively solving the problem that the pump shells and blades are easy to generate internal defects such as cracks and air holes in the laser cladding repair process, and avoiding the problems of welding deformation, large heat influence area, easy generation of heat cracks and the like in a conventional processing method; the method disclosed by the invention is capable of generating a high-amplitude residual compressive stress on the surface of a material, effectively improving the fretting fatigue resistance of the material, comprehensively improving the mechanical properties of the material, and greatly prolonging the fatigue life of the material, thus achieving the purposes of prolonging the life and improving the reliability and safety.

A clamping apparatus for fixing and non-rotatably clamping threaded shafts, particularly threaded shafts used as electrodes for eroding threads, comprises a hollow cylindrical shaft with a clamping sleeve member located at its front end. The clamping sleeve member has a central bore and a rectangular aperture opening into that central bore. A rectangular clamping member is slidably received in the aperture and comprises at its front surface, facing the central bore, a number of thread convolutions matching the thread convolutions of the shaft to be clamped. For moving the clamping element towards a threaded shaft received in the central bore, a rotating collar is provided, located around the outside of the clamping sleeve member, and having a an inner circular surface with a diametrically gradually enlarging recessed portion into which the clamping element protrudes. By rotating the collar, the clamping element is radially moved toward a threaded shaft inserted into the bore, until the thread convolutions of the clamping element engage the thread convolutions of the shaft in the bore.

An air-conditioning system operable at different states employs a control unit including a receiver and a transmitter. The receiver is connected electrically to a switching device for a compressor of the air-conditioning system. The compressor is installed at a remote location exterior to a building. The receiver is responsive to an encoded radio signal to provide an electronic control signal for actuating the switching device. The transmitter is installed within the building and is electrically connected to a thermostat within the building that responds to temperature changes to provide a temperature control signal. The transmitter upon receipt of the temperature control signal transmits to the remote location the encoded radio signal for operating the air-conditioning system at one of the different states.
