Abstract: 1,239,322. Pressure indicators. CARBORUNDUM CO. March 5, 1969. No.11684/69. Heading G1L. In a pressure indicating device in which a piston 17 is slidably mounted in a housing 11 and is subjected on the upper end to a high pressure through an aperture 18 and has the lower end exposed to a lower pressure the arrangement is such that the piston 17 is normally held adjacent to a partition 12, by a coil spring 20, in which position an indicating means 15, having a head 15A of a magnetically attractive material is held in the position shown by the poles 21 of a magnet 19 and is held in such position by balls 37 engaging a head 34 and an inclined surface 36 on the interior of an indicating button 28 but as soon as an increase in pressure through aperture 18 moves the piston 17 downwardly against spring 20 the magnetic influence exposed by magnet 19 on the head 15A decreases and the head 15A is attracted towards a magnet 27 to move the head 34 out of contact with balls 37 thus allowing a spring 32 to move the button 28 to the projected position.

Abstract: 1,251,280. Fluid-pressure servomotor systems. LUCEAT. Dec.18, 1969 [Dec.20, 1968], No.61652/69. Heading G3P. A relief valve 10, which may be used to relieve either excess pressure or excess vacuum within its inlet A, has connected thereto a pressure pilot valve 12 and a vacuum pilot valve 14, the two pilot valves being of identical construction and being responsive respectively, to excess pressure or excess vacuum at the inlet A. Up to a predetermined excess inlet pressure, such inlet pressure is transmitted to a diaphragm chamber C of the pilot valve 12, and from chamber C is communicated through a check-valvecontrolled passage 114, chambers F and E, and a passage 136 to relief valve control chamber B, such communication being possible as long as the inlet pressure acting within chamber C does not overcome the force of spring 96 and hence pilot valve member 70 remains remote from a seat surrounding a duct between chambers E and F but seated on a seat surrounding a duct between chambers D and E, the former of which is vented to atmosphere via port 81. Upon the pressure rising, the diaphragm of chamber C moves upwardly as does closure member 70. As a result the inlet pressure ceases to be communicated to chamber E, the pressure within chamber B is relieved to atmosphere via passage 136 chambers E and D and port 81, and hence the relief valve opens. The pressure at which relief occurs is adjustable by varying the loading on spring 96. Upon the inlet pressure exceeding a certain level of vacuum, pilot valve 12 becomes inoperative on account of the check valve in passage 114. Instead, vacuum is communicated to chamber D' of vacuum pilot valve 14 with such vacuum acting on a diaphragm 66' the other side of which may be exposed to positive or negative pressure. Upon the degree of vacuum reaching a limit predetermined by springs 96', diaphragm 66' moves in opposition to spring 96' and hence valve member 70' moves upwardly. Accordingly, vacuum supplied to chamber D' from inlet A is communicated to chamber E', and thence, via duct 136', to chamber B as a result of which relief valve 10 opens, the degree of vacuum at which relief occurs is adjustable by varying the loading of spring 96'. Alternatively, valve 14 may be omitted and the check valve in passage 114 of valve 12 removed. In such an arrangement, transmission of vacuum from chamber C to chamber F is no longer impeded and pilot valve 12 serves to actuate relief valve 10 under both excess pressure and excess vacuum conditions.

In a centrifugal pump having a shaft sealing ring 4 which is resiliently urged, as by springs 5, against a mating ring 3 when the shaft 14 is stationary, Fig. 4, and is lifted therefrom by centrifugally actuated weights 8 during operation, Fig. 3, the weights 8 comprise spheres disposed between recesses 16 and 17 in annular discs 13 and 7 respectively, the disc 13 being fixed to the shaft and the disc 7 being slidable on the shaft and the outer surfaces of the recesses being conical whereby as the spheres 8 move radially under centrifugal force the discs are forced apart and bolts 10 which are secured to the disc 7 and pass through holes in the disc 13 and in a lift-off ring 9 lift the ring 4 during pump operation. The recesses 16, 17 are divided into segments (19, Fig. 2) by circumferentially spaced radial webs (18). A bellows 21 extends between the ring 4 and a ring 23 which is held by a clamp ring 22 and sealingly engages both a sleeve 12 on the shaft and the disc 13. The springs 5 are compressed between the ring 22 and a guide ring 24 which abuts the sealing ring 4. During operation, shaft leakage is prevented by blading 27 and 28 on the pump impeller 1 and a further impeller 2, respectively. In a modification, Fig. 1 (not shown), the ring (4) is urged towards ring (3) by a resilient ring (33).

In an electric clock the escapement action is controlled by a torsion pendulum (not shown) and the winding action is performed by a D, C, motor 5 controlled by a travelling nut 28 having a conical surface, the nut being displaced by a spring barrel 11 driven by the motor through a worm gear 10 and the motor being controlled by a switch 31 having a follower 35 which engages the surface of the nut. The spindle 12 of the spring barrel has a screw-threaded portion 27 which meshes with the nut so that as the spring unwinds the nut travels towards the gear 10 until the follower 35 is released, thereby switching on the motor. The worm 9 of the motor rotates the gear 10 thus winding the spring and causing a pin 29 to rotate the nut 28 until the nut actuates the switch 31 to deenergize the motor. The escape wheel 20 is controlled by a pallet carrier 21 pivoted on a spindle 24 and having pallets 22, 23.
