Abstract: A variable mode microwave water cut monitor includes a test cell (8) which contains a fluid sample. Valves (64,68) control the provision and removal of the fluid sample to effect different modes of operation for the monitor, a normal test mode and at least two calibration modes. A source (3) provides microwave energy to a first antenna (7) which in turn provides the fluid sample in the test cell with microwave energy. A second antenna (9) receives the microwave energy that has passed through the fluid sample. A detector (22) detects the received microwave energy and provides a signal representative thereof. An indicator (44) provides an indication of the water cut of the fluid sample in accordance with the received signal power, a phase difference between the transmitted microwave energy and the received microwave energy, and internally recorded calibration data for water alone and oil alone.

Abstract: Two lifting units (1, 2) have lifting grabs (3) for lifting individual concrete slabs (29) off a prestressing bed on which they have been cast and then stacking them on a pair of support beams (6) to form a pile (28). Once the pile (28) has been formed, the lifting units (1, 2) use lifting hooks (16) contained within an upper frame (14, 15) to lock into the beams (6). A jacking mechanism (13) then raises the upper frames (14, 15) relative to lower frames (11, 12) to lift up the entire pile of slabs (28). The lifting units (1, 2) are mounted on rails (9) which run along the sides of the prestressing bed and lead off to a stockyard where the pile of slabs (28) is taken by the lifting units (1, 2) for storage. During transfer of the individual slabs (29) to the pile (28), drilling units (4) are swung under each slab (29) to drill drainage holes. One of the lifting units (1) has a container (21) for dispensing and collecting the beams (6).

Abstract: An exhaust gas purification system for a diesel engine (2) with a lean NOx catalyst (4) includes a temperature detecting means (6), an excess air ratio changing means (8) capable of changing an excess air ratio without changing a fuel injection amount, a control means for controlling the excess air ratio changing means (8) so as to increase the excess air ratio when the exhaust gas temperature is higher than an upper limit of a predetermined temperature range and to decrease the excess air ratio when the exhaust gas temperature is lower than a lower limit of a predetermined temperature range. In the exhaust gas purification system, the exhaust gas temperature can be controlled to the temperature range independently of the fuel injection amount.

IPC: B60T11/224
Filed: 1992-09-09
Abstract: In a two-step valve, in particular a brake valve, the effective cross-sections of two cross-sectional steps come successively into effect. First of all, the larger effective cross-section is used for filling a system. After a transitional phase, the smaller effective cross-section alone is then used for the application of the working pressure. The valve has a relief passage (24, 30) which is situated between the pressure space with the larger effective cross-section and a reservoir and which, during the pressure stage of the valve, during which only the smaller effective cross-section is operative, is open or can be opened. In order to protect a working element exposed to the working pressure from impermissibly high pressures and in order to achieve a limitation of the displacement stroke of the pressure piston, the relief passage (24, 30) is closed when a predeterminable working pressure is exceeded. For this purpose, an overload protection valve exposed to the working pressure is arranged in the relief passage (24, 30).

Abstract: In a housing (32) which has a housing axis (A) and encloses a first cam surface (54) arranged around the latter, a body of revolution (38) is mounted to rotate about the housing axis (A). The body of revolution (38) has an axial extension (76) for coupling an actuating member (80) and, on its circumference, has a toothing (86) and, furthermore, a second cam surface (40) by means of which it is supported against the first cam surface (54) in order to bring about an axial displacement dependent on its rotation. A first screwed body (60) is furthermore rotatable about the housing axis (A). A second screwed body (70) is held fast against rotation, is designed to exert an actuating force on a brake shoe (24) and is connected to the first screwed body (60) by means of a pair (72) of readjusting threads. A resetting shaft (90) is mounted at a lateral distance from the housing axis (A). Coupled to the first screwed body (60) is a pinion (112). Arranged around the resetting shaft (90) is a coupling arrangement (98) which is in engagement via a toothing (89) with the toothing (86) of the body of revolution (38), with the result that a limited torque for the axial readjustment of the brake shoe (24) is transmitted from the body of revolution (38), via the coupling arrangement (98) and the pinion (112), to the first screwed body (60). To achieve a frictional engagement, the pinion (112) is spring-loaded in the axial direction and connected to the coupling arrangement (98) by a one-way slipping clutch, rotation of the first screwed body (60) during operation being permitted only in a direction which reduces the brake release clearance. <IMAGE>
