Abstract:
기기의 배관에 설치되어, 배관 유로 내의 압력을 일시적으로 축압하고, 혹은 펌프 등에 의해 배관 내에 발생하는 유체 압력의 맥동을 흡수하는 어큐뮬레이터에 있어서, 0℃ 이하의 저온 환경에서의 블레이더(3)의 반복되는 굽힘과 인장 운동에 대한 내구성을 향상시키고, 가스실의 쿠션 가스의 감소를 유효하게 방지하기 위해, 블레이더(3)가, 예컨대 중심 탄성층(321)과, 그 바깥쪽의 가스 차폐층(322)과, 더 바깥쪽의 외측 탄성층(323)의 적층 구조를 가지며, 상기 중심 탄성층(321), 가스 차폐층(322) 및 외측 탄성층(323)이 폴리아미드 수지로 이루어지고, 상기 가스 차폐층(322)은 상기 중심 탄성층(321) 및 외측 탄성층(323)보다 굽힘 탄성률이 높아지도록 하였다.
Abstract:
The invention concerns a reflector (100) for reflecting electromagnetic waves, which waves are emitted into a conducting structure (101) from at least one antenna (4) situated at a distance (d') from the reflector (100). The distance (d') is calculated based on measured emitted and reflected waves to and from the reflector (100), respectively. The inventive reflector (100) comprises a reflector disc (102), an elongated body (103,103') having a first longitudinal end (105) and a second longitudinal end (106), the first longitudinal end (105) being fastened to the reflector disc (102) and the second longitudinal end (106) being fastenable to an accumulator piston (107, 107'). Said elongated body (103, 103') further comprises at least two telescopically interconnected reflector tubes (103, 103') rendering reversible adjustment of the elongated body's (103, 103') longitudinal length around a predetermined equilibrium length possible. The invention also concerns a piston accumulator (2,116) applying the reflector, and a method for measuring said distance (d').
Abstract:
An apparatus for determining the weight of a payload (44) in a bucket (24) of a machine (20) where the bucket (24) is attached to a chassis (26) of the machine (20) by a linkage. The apparatus comprises an energy storage device (82) for storing potential energy of the bucket (24), payload (44), and linkage when the bucket (24) is moved from a first suspended position to a second suspended position. A mechanism (86) provides physical data corresponding to a physical change in the energy storage device (82) caused by storage of the potential energy and a processor (116) calculates the weight of the payload (44) using the physical data.
Abstract:
Die Erfindung betrifft einen Hydraulikfluidspeicher (30) mit einer Hochdruckkammer (32) und einer Niedrigdruckkammer (33), wobei die mit einem Ausgleichsvolumen (36) versehene Hochdruckkammer (32) in der Niedrigdruckkammer (33) angeordnet ist. An dem Hydraulikfluidspeicher (30) ist ein externer Anschluss (34) für das Ausgleichsvolumen (36) vorgesehen, über welchen das Ausgleichsvolumen (36) mit einem Gas mit einem vorgebbaren Druck befüllbar ist.
