Title: Pressure regulator display
Inventor: HECKING WILLI
IPC: F16K37/00
Filed: 2009-06-04
Abstract: Apparatus for adjusting and displaying pressure in a pressure regulator includes a valve assembly to control the pressure, the position of the valve assembly being adjustable by the tension of a spring 32 interacting therewith. An axially movable spring cap 40 is arranged on a threaded actuator 36, and handle 24 is rotated to adjust the axial position of the spring cap 40 and thus the spring tension. A coarse-threaded shaft (42, Fig. 4) parallel to the threaded actuator 36 interacts with the spring cap 40 such that axial movement of the spring cap 40 rotates the shaft 42. Indicator means to display the adjusted pressure comprises a cogwheel (48, Fig. 5) that engages with teeth on the shaft 42. The cogwheel 48 drives an indicator (26, 28, Fig. 3) to display the adjusted pressure.

Title: Calibrating weighing scales
Inventor: HOLLIMAN ROGER JOHN
IPC: G01G23/01
Filed: 2009-07-02
Abstract: A weighing scale has a calibration weight 25 which is movable between a deployed condition and a retracted condition. The deployed condition of the calibration weight is such that the calibration weight sits upon a load-cell 19 of the scale in order to calibrate the scale. The calibration weight is moved between its deployed and retracted conditions by the relative angular displacement between two members 30, 31. The reaction may be caused by one or more inclined surfaces (43, Fig 7) on the two members. The two members may be coaxial rings 30, 31. One of the rings 31 has a plurality of slots (42, Fig 7) distributed around its circumference, the other ring 30 has a plurality of projections (41, Fig 7) which are designed to nest in the slots of the first ring. The angular displacement of the second ring may cause the lowering of the calibration weight on the first ring. An abutment which causes the calibration weight to separate from the rings may be located on a saddle member which is connected to the load-cell and also supports the items submitted to the scale. A means to limit the magnitude of either positive or negative load that can be imposed on the load-cell may be incorporated.

Title: Improvements in hydraulic brakes for use with drop hammers
IPC: B21J13/06
Filed: 1928-04-05
Abstract: 300,870. Urbanek, J., and Schneider, A. April 5, 1928. Power hammers.-A braking-device between the lifting-rod &c. and the top of power hammers comprises two hydraulic brakes in combination, one of them chiefly active during the downward movement of the lifting-member after the blow and the other active only during the ascent of the lifting-member. A hydraulic cylinder 2 is provided in the tup 1 and the lifting plunger 3 has disc pistons 4, 5 working therein. The cylinder cover is engaged during the lift by a collar 6 on the plunger 3, which has a central air chamber communicating with the cylinder 2 by holes 10. Ports 9 in the piston 4 are adapted to be closed by a plate valve 7 supported by a light spring 8 and grooves 11 are provided in the cylinder wall. When the tup delivers a blow and the pistons descend in the cylinder 2, the braking liquid passes through and around the piston 4, and some of it through the holes 10 into the plunger air chamber. The, lower part of the cylinder 2 is of diminishing diameter so that the outlet cross-section of the fluid displaced by the piston 5 decreases, whereby the braking force is kept approximately constant until the lifting-device comes to rest. When the lifting-device moves upwards the plate valve '7 is forced downwards and closes the ports 9, causing the fluid to return to the lower part of the cylinder 2 through the grooves 11 only; the merging out of the grooves 11 at the top ensures easy contact of the collar 6 with! the cylinder cover. The expensive tapered and grooved construction of Fig. 1 may be avoided by the modified construction shown in Fig. 4, wherein grooves 16 are provided in the circumference of the piston 4 and a port 14 leading to the air chamber of the plunger 3, or by providing auxiliary ports through the piston, or by leaving play between the piston and cylinder wall. Shoulders 19 may be provided on the piston 4, Fig. 5, engaging a corresponding cavity in the tup cover to ensure powerful throttling of the fluid escaping from the space above the piston to avoid violent contact of the collar 6 with the tup cover. In the modification shown in Fig. 6 the piston 4 is provided with a resilient washer 12 the space behind which communicates through ports 13 with the upper side of the piston so that on the up-stroke of the lifting-device the washer is forced against the cylinder wall. The hydraulic brake device may be combined with a steam or compressed air operated tup cylinder of known construction shown in Fig. 7, wherein the outlet 17 is arranged above the inlet 18 and is overrun by the piston during the stroke forming a cushion beneath the piston.
