Abstract: 533,710. Closures for tanks. METALLINDUSTRIE GES. Aug. 14, 1939, No. 23400. Convention date, Sept. 8, 1938. [Class 125 (iii)] A closure for fuel tanks, cooling water vessels and the like, has a valve and a resilient diaphragm, subject to atmospheric pressure over the whole of its external area, which operates automatically to equalize the pressure inside and outside the tank. The cover 1 contains packing 3 beneath the rim of a casing 2 which has a sunken central part containing a spring 4, the upper end of which abuts on a resilient retaining member 6 having ends which pass through slots 5 in the casing 2. An intermediate plate 7 rests on packing 8, and has a central aperture for the stem 13 of the valve plate 14 which is normally lifted by the spring metal diaphragm 18 to engage the annular ridge on the plate 7. When the liquid level falls in the tank and the internal pressure is thereby reduced, atmospheric pressure on the diaphragm 18 causes it to drop and lower the valve plate 14, thus permitting the pressure to be equalized by means of the valve opening and the channels 10 in the plate 7. When an excess pressure develops in the tank, the cover 1 is lifted against the pressure of the spring 4 ; the spring is held by the plate 6 the ends of which rest in bayonet grooves in the container wall. A conical valve. or ball valve may be used in place of the plate valve 14.

Title: Improvements in or relating to calculating machines
IPC: G06C23/04
Filed: 1925-09-19
Abstract: 241,177. Friden, C. M. F. Oct. 8, 1924, [Convention date]. Multiplying and drividing apparatus.-In an independently operated machine of the type having a rotatably adjustable differential setting mechanism with locking means for holding the parts in set position, the looking means is moved into operative position by a movement of the main crank handle from its neutral position and is held in locking engagement during subsequent movements of the crank through neutral position, the usual crank handle pin or equivalent means being eliminated. As shown applied to the type of machine described in Specification 207,858, the operating crank 37, Fig. 7, is mounted on a shaft 38 and through gearing 39, 41, 42. 43, Fig. 5, drives a. spindle 71 connected in the known manner with the spindle 36, Fig. 3, carrying the totalizer actuating segments and the adjustable setting discs 12. Rotation of the shaft 36 causes a cam 35 thereon to rock an arm 34 to force the locking fingers 33 into engagement with the notched segment 31 of the setting discs. In multiplying- operations, the fingers maintain the setting discs locked by the engagement of a depending arm 51 on one of the fingers with a disc 52 mounted on a spring-controlled shaft 53. The disc 52 is normally held at one side of the arm 51 but is moved beneath the arm on the initial movement of the crank. This movement is effected by a bell crank lever 58, Fig. 4, the corner of which engages the spring housing 56, the arm 59 of the bell crank being raised bv the end 61 of a pivoted lever 78 having a projection 92 engaging a pair of notched discs 81, 83, Figs. 7 and 9, associated with the gear wheel 39. In the neutral position of the crank, the notches 82, 84, are in alignment but on rotation of the crank, they are. moved out of line by reason of the limited play permitted between the discs 81, 83 through the pin and slot connections 85, 86, and through a third disc 87 which is pinned to the disc 83 and is engaged by a spring-controlled frictional-drag bar 91. When the crank is brought to rest, a flat portion 88 on the disc 87 causes the disc 83 to assume the normal position and thus restore the locking disc 52. In adding and subtracting operations the usual control key 64, Fig. 8, is manipulated to rock the lever 66<1> so as to raise the extension 62 and thereby rock the bell crank lever 58 to move the looking disc to an inoperative position beyond the arm 51.

Abstract: 1,136,044. Frequency discriminator. CSFCOMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 26 May, 1966 [15 June, 1965], No. 23749/66. Heading H3A. A frequency discriminator for demodulating frequency modulation signals comprises a field effect transistor with the input signals applied between its two electrodes 19 and 20, Fig. 4, the input also being applied to the gate 18 with a phase shift dependent on frequency. In Fig. 4 the source 11 is inductively coupled to a circuit 7 tuned to the carrier frequency and coupled to the gate 18. A second tuned circuit comprises windings 12 and 13 inductively coupled to the circuit 7 and tuned by a capacitor 14. At carrier frequency the voltage across electrodes 19 and 20 is in quadrature with that applied to the gate 18, but this phase relationship varies with frequency giving rise to an output across the filter formed by resistances 21 and 22 and capacitor 23. A bias source is preferably connected between points 24 and 25 and is essential if gate 18 is insulated. Another arrangement, Fig. 5 (not shown), uses only capacitors and resistances and is suitable for manufacture as an integrated circuit. The source (11) is connected, if necessary through a capacitor (28), to one electrode (19) of the F.E.T., and the junction of a capacitor (30) and resistance (31) connected across the source provides the quadrature phase signal to the gate (18). The other electrode (17) provides the output and is connected to earth through a filter (capacitor 34 in parallel with resistance 35) and to the gate through a gate leakage resistance (33) and a bias source if the gate is insulated.

Filed: 1938-08-11
Abstract: 517,973. Conditioning air. FLEISHER, W. L. Aug. 11, 1938, No. 23761. [Class 137] [Also in Group XIII] Air for an enclosure is conditioned by passage through a dehydrator 4, which by latent heat evolved raises the temperature, and is delivered at this temperature, which is above the dewpoint of the surrounding air, through a long conduit, e.g., a mine shaft to a remote distributing unit 22 where it is cooled at the point of delivery to the enclosure and may be mixed with cool air from the enclosure. Fan 9 draws air through a casing 4 enclosing a layer 5 of glass wool or the like on to which a dehydrating liquid such as lithium or zinc chloride in solution is sprayed from nozzles 8. Moisture removed from the air dilutes the liquid in a sump 7, altering its specific gravity, and a hydrometer 10 controls the valve 11 in the fuel supply to a burner 12 which heats a regenerator 13. A pump 6 supplies part of the liquid to the regenerator and part through a cooler 34 for re-use in the casing 4. The partially-dried air is passed through cooling coils 15 and water sprays 18, but either the coils 15 or the sprays 18 may be used alone. The air is distributed to the enclosure through ducts 22. A hygrostat 23 in the enclosure may be used to control valve 11. In Fig. 3, the conditioned air enters a distributor 26 through duct 22 and may be further cooled by coils 28. Recirculated air from a duct 29 passes heating or cooling coils 30 and a thermostat 31 controls a damper 32 in duct 22, and the conditioned air enters the enclosure through discharge ducts 27. The dehydrating liquid may be passed to the regenerator 13 by an independent pump which, with the heater 12, is controlled by the hydrometer 10, or by psychrometric or hygrostatic means in the enclosure. Specifications 331,824, [Class 137], and 449,685 are referred to.
