Title: Improvements relating to hydraulic testing means
Inventor: HINDE PHILIP BENJAMIN
IPC: G01N3/10
Filed: 1963-10-08
Abstract: 1,059,113. Testing physical properties. W. & T. AVERY Ltd. Sept. 29, 1964 [Oct. 8, 1963], No. 39518/63. Heading G1S. A device for adjusting the effect of elasticity of components of a hydraulically powered testing apparatus comprises a ram and a supply system to supply hydraulic liquid to the ram, the device comprising means responsive to increasing liquid pressure in said system and ram for decreasing the hydraulic liquid capacity of the supply system and ram. The device comprises two cylinders 6, 7 in coaxial alignment with coaxial pistons 11, 12 respectively of different cross-sectional areas joined together so that as one piston 11 or 12 sinks into its cylinder the other emerges. A compressed helical spring 13 bears against the end of the larger piston 11 and the inner end of cylinder 7. Each cylinder has an inlet/outlet passage 15, 16 for connection into the hydraulic circuit of a testing machine. In a hydraulic testing machine the hydraulic fluid is fed from a reservoir 20 via a main chamber 19 and a needle valve 21 to the supply system 22 which is connected to a hydraulic ram 24. The inlet/outlet passage 15 is connected to the main chamber 19 and the passage 16 to a delivery pipe 23 so that the constant pressure difference achieved by a valve 21 and a piston 29 also exists between the liquid parts within the cylinders 6, 7. Since the pistons 6, 7 have different crosssectional areas, with deformations of the parts due to elasticity, the larger piston 6 will be forced out of its cylinder against the action of the spring 13 forcing the cylinder 7 into its cylinder and so displacing some of the liquid from the latter into the supply system 22 to decrease the capacity thereof. As the pressures fall the reverse takes place and the capacity is increased.

Filed: 1972-08-25
Abstract: 1376398 Breaking pieces J HOCHREUTER 25 Aug 1972 39681/72 Heading F2X  A shearing pin safety coupling for connecting two shafts comprises two parts 3, 4 formed with external flanges 18, 21 having bushes 19, 26 distributed around them and axially aligned so as to hold shearing pins 20. The flange 21 has an integral annular projection member 23 overlapping the flange 18, with a facing ring 24 attached to it by screws 25. On the cylindrical inner face of the projection formed by member 23 and facing ring 24, and on the cylindrical outer face of the flange 18, there are provided bearing surfaces in the form of ball-bearing races 27, 28 of V-shaped (or, alternatively, semi-circular) cross-section which hold a set of ball bearings 29. If the shearing pins 20 break during operation due to the permissible torque being exceeded, the ball bearing comprising the races 27, 28 and the balls 29 prevents axial separation of the two coupling parts 3, 4. In addition, insofar as the balls 29 lie without play against the two pairs of inclined surfaces in the ball races 27, 28 any radial movement between the coupling parts 3, 4 is also precluded. At high rotary speeds, such movements could result in correspondingly high eccentricities and centrifugal forces. The bearing is provided with a grease or oil filling which necessitates an appropriate sealing. For this purpose, the mutually-facing end surfaces of the member 23 and the facing ring 24 are formed as an endless rabbet 30, a sealing ring in the form of a lip 31 is provided between the facing ring 24 and the flange 18, and an O-ring 32 is provided between the member 23 and the flange 18. Each coupling part is formed at its outermost end with internal toothing 1, 2 meshing with crowned outer teeth 5, 6 formed on a shaft hub 7, 8. Each hub 7, 8 has a groove 9, 10 for the reception of a plate spring to ensure positive connection with a drive shaft or driven shaft. In an alternative embodiment (Fig. 2, not shown) a similar shearing pin safety coupling is described formed as a claw coupling.
