摘要:
The present invention relates to an apparatus for monitoring the process performance of a laser system with a high-power optical fiber cable (3), specifically an optical fiber cable made for transmitting power levels up to and exceeding 20 kW. Generally the fiber cable has an entrance end (1) for an incident beam-light and an exit end (2) where the beam-light is leaving the optical fiber, and wherein at least one of the ends is provided with a connector device (4,5) having sensor means (14) for monitoring the optical fiber cable status. According to the invention the sensor means (14) are located inside the connector device (4,5) and arranged for monitoring and controlling a laser application process during action as well as detection of conditions within the connector device, such as scattered light, temperatures or the like. The sensors (14) are connected to a fiber interlock circuit (30) to activate an interlock break when measured signals are higher than threshold levels(31) and the comparison of the signals to the threshold values is integrated inside the connector device (4, 5). Preferably the sensor means includes diodes (15,16,17) of the light sensor type located in the rear part of the connector device (14,15). A very fast interlock break system is then provided which has the signal control integrated inside the fiber connector.

Frame assembly (1) comprising at least a first frame member (2) joined together with a second frame member (4). The first frame member (2) comprises a stepped first end section (9) comprising a first end surface (10) and a second end surface (11) at an angle to the first end surface (10). The second frame member (4) comprises a third end surface (15) perpendicular to the fourth end surface (16). The first end surface (10) comprises a pin (7) intended to be inserted into a hole (8) in the third end surface (15), or vice versa. The pin (7) and/or the hole (8) comprises an upper part (17, 22) that is chamfered in such a way that, when the pin (7) is inserted into the hole (8) and the third end surface (15) is moved towards the first end surface (10), the second frame member (4) is moved in the direction towards the second end surface (11) by the action of the chamfered upper part (17, 22).

A system (101) for controlling the indoor climate in a building, at least comprising a first air duct (102) for supply air, a second air duct (103) for exhaust air, an exhaust-supply air heat exchanger (104) for selective transfer of heat between supply air and exhaust air, a water system (105) having a hot water circuit (106) and a cold water circuit (107), a water-supply air heat exchanger (108) at the first air duct (102) and a water-exhaust air heat exchanger (109) at the second air duct (103), both for selective connection to the hot water circuit (106) or the cold water circuit (107), a heat pump (110) for selective transfer of heat between the water circuits (106, 107), wherein first fan devices (111, 111') circulate ventilation air (A2, A3) to/from the building, wherein the system has a passage (113) for admitting a partial flow (A1') of outdoor air (A1) upstream of the water-exhaust air heat exchanger (109), wherein second fan devices (112) suck or blow the partial flow (A1') together with exiting circulated ventilation air (A6), through the water-exhaust air heat exchanger (109), wherein the second fan devices (112) provide a maximum air flow rate at least 1.7 times greater than the air flow rate from the first fan devices (111, 111').
摘要:
The present invention relates to an air supply apparatus (102) for a two- stroke stratified scavenging combustion engine (100). The air supply apparatus includes an air cleaner (124) having an air outlet (130) and a partition (131), such that the partition substantially divides the air outlet into a first section (132) and a second section (134). The air supply apparatus further includes a carburetor (126). The carburetor includes a passage (136), a throttle valve (140) and a choke valve (138), such that the throttle valve and the choke valve substantially divides the passage into an air portion (142) and a mixture portion (144). Further, a first aperture in communication with the first section of the air outlet is provided corresponding to the air portion, and the second aperture in communication with the second section of the air outlet is provided corresponding to the mixture portion. Moreover, an area of the first section is different from that of the second section.

The invention relates to medicine. The inventive device for preventing and treating locomotion disorders comprises two shoes, each of which is provided with pneumatic modules whose number for each shoe is equal to 2. A compressor and receiver are common for all pneumatic modules, wherein said receiver is connected, by means of a separate air hose, to each pneumatic chamber which is provided with an additional electric pneumatic valve selected according to a condition of supplying air from the receiver to the pneumatic chamber therethrough, discharging the surplus of said air from the pneumatic chamber to the atmosphere and obtaining in the pneumatic chamber a pressure equal to an atmosphere pressure. The electric pneumatic valves and pressure sensors are connected to a microprocessor provided with an air supplying program simulating different walking or running modes. The shoe comprises a sole provided with a unit for fixing pneumatic chambers which increase the volume thereof when they are supplied with pressure in a vector mode only in a perpendicular position with respect to a pelma surface. The shape and size of the pneumatic chamber of one pneumatic module correspond to the shape and size of the pelma metatarsal area comprising medial and lateral sections of Vater-Pacinian corpuscles, and the shape and size of the pneumatic chamber of the second pneumatic module correspond to the size and shape of a calcaneal area also containing the Vater-Pacinian corpuscles. The invention variants are characterised by the pneumatic chamber embodiment.
