Title: Improvements in or relating to stress relieving spring assemblies for valves
IPC: F16K31/05
Filed: 1962-07-04
Abstract: 957,267. Valves. LINK-BELT CO. July 4, 1962 [July 11, 1961], No. 25712/62. Heading F2V. A valve, e.g. of the disc type, is actuated by a fluid or electric motor or manual means through a worm 28, worm wheel 44, a drive sleeve 46 and a nut 72 splined thereto in which is threaded the valve stem 16; the nut 72 is connected to an annular cage 88 containing a number of springs 118. Any over-run of the transmission, causing valve closing torque to be exerted on the stem 16 after the valve is seated, is dissipated by the nut 72 and cage 88 rising against the bias of the springs 118. The upward movement of the cage 88 is defined by a flange 106. Lateral shifting of the springs 118 is prevented by upper and lower bolts 114, 132, the latter being associated with spacer 130. The cage 88 is held stationary by a key 140 in an elongated slot 136, which arrangement is also employed to indicate the cage displacement. The springs 118 will also act in a similar manner to relieve stresses due to expansion of the valve stem when subjected to a temperature increase. Conversely the springs will maintain the valve seated if the stem cools more rapidly than the surrounding parts. The spring assembly may be installed in an existing valve.

Title: Physiological reaction time meter
IPC: A61B5/16
Filed: 1956-08-23
Abstract: 786,414. Measuring physiological reaction time. YLINEN, K. J. Aug. 23, 1956 [Aug. 26, 1955], No. 25763/56. Class 81 (2). [Also in Group XVIII] A physiological reaction time meter comprises a channel for a falling body, a support for the body at the upper end of the channel, manuallyoperable means for withdrawing the support, means for delaying the withdrawal of the support after the manually-operable means has been actuated, means for giving a signal when the support is withdrawn and the body starts falling and a braking member extending along the channel for operation by the user on reception of the signal in order to stop the fall of the body, the distance fallen giving a measure of the reaction time of the user. A coin 5 is inserted at the top of the channel 4 and is supported by a pin 18 carried on one end of a spring 19 which is fixed at the other end to a frame. On pressing a push-button 29 the pin 18 is withdrawn, a second pin 22 carried by an arm 23 is inserted in the channel 4 to support the coin 5 and the push-button 29 is retained in depressed position by engagement of a suction cup 30 on the push button 29 with a plate 32. Air slowly enters the suction cup 30 through the clearance between a screw 34 and the plate 32 to destroy the suction seal so that the push-button 29 is returned to its initial position by a spring 25. The arm 23 then moves so that pin 22 is withdrawn from the channel 4 and a hammer 37 carried by the arm 23 strikes a bell 38 or operates a visible signal (not shown) to indicate the start of the fall of the coin 5. A lever 12 pivoted about a fixed point 10 and secured at one end to a movable bar 3 forming one wall of the channel 4 is held against a spring 14 by a pin 39 so that the movable bar 3 permits the coin 5 to fall. On receiving the signal the operator presses a push-button 41 which releases the lever 12 from the pin 39 so that the lever 12 is actuated by the spring 14 to move the bar 3 inwardly of the channel 4 and stop the fall of the coin 5. The movable bar 3 may alternatively be operated electromagnetically. A scale 44 calibrated in hundredths of a second is marked on a glass plate arranged over the channel 4. If the coin 5 is stopped in the channel 4 adjacent an electric contact plate 45, it closes a circuit which includes the movable bar 3 and operates prize delivering mechanism. If the coin 5 is stopped adjacent a tube 51, the coin is returned to the operator.

Title: Filter
IPC: B01D29/46
Filed: 1971-04-19
Abstract: 1350152 Edge filter BENDIX CORP 19 April 1971 [1 April 1970] 25765/71 Headings B1D and BIT A filter apparatus 10 for removing particles of diameters 0.01 to 10 microns from a fluid, e.g. air, comprises a stack of washers 26 mounted on a threaded rod 44. The stack is mounted within a two part casing 12, 14 with fluid inlet 20 leading to an annular inlet space 22 around the outside of the washer stack and filtered-fluid outlet 42 leading to an annular outlet space 32 between the inner surfaces of the washers and rod 44. Fluid passes from the inlet to the outlet along passages formed as grooves in the surface of each washer, one end of which 140, 142 (Fig. 3) communicates with the inlet space 22 whilst the other end 194 communicates with outlet space 32. A number of pockets 168 are formed along each passage and these are arranged to trap the solid particles by centrifugal deposition. The pockets 168 may have a combined inlet and outlet 146 as shown in Fig. 3 (also Fig. 4, not shown) which is offset to one side of the pocket so that incoming fluid will swirl in the pocket and generate the centrifugal forces. Alternatively, the pockets may have separate inlets and outlets mounted at adjacent corners of the pocket (Figs. 6 and 7, not shown), in which case the inlet and outlet are connected outside the pocket to allow some of the fluid flow to by-pass the pocket. In a third embodiment (Fig. 8, not shown), there is a single fluid inlet and outlet in the centre of one side of the pocket, but the fluid is directed into and out of the pocket at an angle. The sections of the passageway between pockets, suitably, are straight for a sufficient length to enable laminar fluid flow to be established between the pockets. The use of the filter apparatus to treat gases at high temperatures, e.g. 1000‹C, to remove organic particles is mentioned. In such a case, the washers become so hot that the removed solids are burnt off and the filter is self cleaning.
