IPC: F16J15/44
Filed: 1968-12-23
Abstract: In a steam turbine or other elastic fluid machine in which a gland case 15 for a labyrinth seal ring 14 is mounted on a main casing 11 by equispaced key assemblies 26 for permitting radial expansion of the gland case and maintaining the proper clearance between the shaft 10 and the seal ring, each key assembly comprises a key 31 and a circular bushing 33 extending through the key and mounted on the main casing for rotation about an eccentric axis so as to permit compensation for any inaccuracy in the position of the keyway 32 relative to the key assembly attaching means 35. The gland case 15 houses arcuate sections of the seal ring supported by leaf springs (28), Fig. 2 (not shown) and is mounted on the main casing 11 by the key assemblies 26 and bolts 16, the latter passing through clearance holes to permit the radial expansion of the gland case. Adjustment of the key 31 in its keyway 32 is performed by rotating the bushing 33 eccentrically about a dowel stud 35 by means of a tool inserted in grooves 37 in the end face of the bushing. After the key has been adjusted, the bushing is locked by peening or tack welding at 39 and the whole assembly retained by a nut 42.

Patent ES-458973-A1 (ES)
Title: Timing control for fuel injection pump
IPC: F04B1/06
Filed: 1977-05-20
Abstract: In a fuel injection pump having a cam and pump plungers movable relative to the cam to translate the contour of the cam into a sequence of pumping strokes. An advance piston connected to the cam to adjust the timing of the pumping strokes is controlled by a hydraulic pressure which increases with engine speed. The advance piston mounts a servo valve having a preloaded biasing spring to prevent the delivery of hydraulic pressure to act on said advance piston until a predetermined speed is reached. A movable stop controls the maximum retard position of the advance piston and responds to the hydraulic pressure which is continuously applied to the movable stop and acts to advance the timing a fixed amount as soon as the engine fires. A load sensing piston actuated by a load related source of fluid pressure is operatively connected to the other end of the advance piston to urge the advance piston in a direction to retard the timing of the pumping stroke in response to increased engine load.

Title: Electronic scales with two ranges
IPC: G01G3/14
Filed: 1980-07-10
Abstract: In order to obtain, in an electronic balance, ranges which are in a predetermined ratio, for example 1:10, there is provided a measuring arm provided with strain gauges adapted to measure the deformation of this arm when it is subjected to a constraint or force. Between the arm and a knife-edge there is disposed a measuring annulus likewise provided with strain gauges adapted to measure the deformation of this annulus when it is subjected to a weighing force. The balance is operated in such a manner that the force or mass of the weight to be measured at the moment of weighing is exerted firstly on the arm via the annulus, until the arm contacts the abutment. This determines the small measuring scale. If the weight is higher than this value, the force is subsequently exerted solely on the annulus which presents a resistance in the region of 10 times greater and determines the second measuring scale.

Title: Stretchable belt conveyor system and belt construction.
IPC: B65G15/34
Filed: 1981-08-25
Abstract: A belt conveyor system has a stretchable belt reinforced by a layer of stretch fabric (16) which includes crimped high strength warp cords (17) woven around transverse cords (18). Low strength warp cords (19) are woven around the transverse cords (18) in an opposite direction to hold the high strength cords (17) in the crimped condition prior to and during molding of the belt.
