Abstract: 701,161. Valves. HYMATIC ENGINEERING CO., Ltd. Nov. 16, 1951 [Dec. 22, 1950], No. 31216/50. Class 135. '[Also in Group XXIV] Mechanism providing a rotary hand control of a rectilinearly movable member is employed as a means for selecting the mass effective on an " anti-G " valve controlling the air flow to inflatable bags placed in an aircraft pilot's flying- suit to restrict blood flow under high acceleration forces. A double-beat valve a is closed by a spring b and is loaded by a mass e when the acceleration forces thereon have overcome a supporting spring f. The effective loading mass may he increased, at the pitot's volition, by dropping thereon one or both of two conical rings g, h, each of which is normally held clear of the mass e by a ring of three balls m, or three balls k, mounted in holes in a fixed cage i and held in their inner positions, as shown, by a manually rotatable cam ring n. The ring n has therein three recesses o adapted to register with the upper ring of holes and balls k, and three longer recesses, Fig. 5 (not shown) to register with the lower ring of holes and balls m, so that on rotary adjustment of the ring n the balls may move into the recesses and allow the corresponding cones to drop on to the mass e. Further rotation of the cam ring n forces the balls inwardly to raise the cones to their original positions.

Hydrocarbons, cracking; rectifiers. -In distilling hydrocarbon oils to produce lighter oils, such as gasoline, the oil after partial vaporization is brought into a region where steam is being generated, whereby the heavier ends of the oil are vaporized. and cracked. Oil from tanks 6, 7 is forced by water admitted below the oil from a pipe 8 through the upper row of pipes 19 of a tube furnace 17 and water is passed through the lower row 23. The streams of oil and water unite in a tee-piece 31 which allows unvaporized oil to pass downwards in the tubes 23 where the water is being vaporized. The mixture of oil vapours and steam passes through the remaining rows 20, 21, 22 of the furnace 17 and through the tubes of a furnace 36 and is discharged by a pipe 45, into a condenser 46, having a series of inlets 47, 48, 49. The condenser is fitted with a series of connected flat spiral pipes 51, 55 serving for the passage of heating or cooling medium, and with perforated baffle plates. Uncondensed vapours pass by a pipe 65 through a series of similar condensers and condensate passes by a pipe 84 into a collecting tank 81. The temperatures of the condensers are regulated to obtain various fractions by passing steam or water through the coils 51, 55, and by varying the height at which the oil vapours are admitted by means of the cocks 47, 48, 49. The temperature of the vapours in the furnaces 17, 36 is about 750‹ F., and the pressure, due to generation of vapours may rise to about 75 lb. The tubes in the furnace 17, 36 may be formed of alloys, containing silicon, iron and, in some cases, calcium, which act as catalysts to promote the formation of lighter hydrocarbons.

Filed: 1971-07-06
Abstract: 1357654 Induction heating apparatus; inverting R J CUNNINGHAM 6 July 1971 [6 July 1970] 31617/71 Headings H2H and H2F [Also in Divisions G3 and H3] Induction heating apparatus comprises a heating coil 134 incorporated in a resonant circuit 114 which is periodically connected to a current supply by a switching circuit 112 arranged to turn off in response to oscillations set up therein and to turn on again after a delay determined by a variable resistor 122. Current in lead 126 charges a capacitor 120, during a time depending on resistor 122, to the breakback voltage of diode 118, whereupon an SCR 116 is fired. The SCR passes current to circuit 114 and sets up oscillations therein; the current in lead 128 subsequently falls and the SCR is rendered non-conductive until capacitor 120 has been re-charged. The current in coil 134 is stated to be as in Fig. 5. In order to stabilize the repetition rate of firing of SCR 116 a photosensitive resistor 122 is used, and a coil 52 in a feedback circuit 50 is coupled to a coil 130 in circuit 114: pulses of current in coil 130 caused by the firings of SCR 116 induce current in coil 52 which affects the mean level of illumination of a light bulb 60 in circuit 50. The illumination of bulb 60 in turn affects the value of resistor 122 which in turn influences the charging time of capacitor 120 and thus controls the interval between switching off and firing of SCR 116. In a further embodiment (Fig. 7, not shown) two pairs of circuits 112, 114 are used (resistor 122 being variable but not necessarily photosensitive), one being connected to the current supply via the switching circuit of the other so as to provide sequential operation of the two heating coils.
