Abstract: 535,383. Vitamins. NATIONAL OIL PRODUCTS CO. Oct. 6, 1939, No.. 27339. Convention date, Nov. 30, 1938. [Class 2 (iii)] A vitamin A concentrate is obtained by treating the unsaponifiable fraction of a marine oil with a de-aerated mixture of an adsorbent for the vitamin and an organic solvent and then eluting the adsorbate. Suitable adsorbents are the oxides and hydroxides of calcium, barium, strontium, magnesium and aluminium and activated clays such as bentonite and tonsil and suitable solvents are non-polar solvents such as benzene, cyclohexane, toluene, chlorbenzene, heptane, hexane, petroleum ether and ethylene dichloride. The de-aeration is effected by stirring and if desired heating, the layer of solvent vapour preventing access of oxygen. The solvent may be only sufficient to wet the adsorbent, the vitamin material dissolved in more solvent being then added, or the whole of the solvent may be mixed with the adsorbent and, de-aerated, the vitamin material being then added. The eluting agent is preferably a mixture of non- polar and polar solvents in a ratio greater than 5 : 1. Suitable polar solvents are methanol, ethanol, propanol, acetone and dioxane. Examples describe the treatment of the unsaponifiable fractions of the liver oils of swordfish, pollack and dogfish, but ling and jewfish are also mentioned.

Title: Improvements in or relating to discriminator circuits for use in automatic frequency control systems
IPC: H03J7/04
Filed: 1938-09-20
Abstract: 522,939. Automatic frequency control Systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and RUST, N. M. Sept. 20; 1938, No. 27448. [Also in Group XL] In a phase type discriminator circuit, for use in A.F.C. systems of the kind shown in Fig. 2 comprising a resonant circuit AC the voltage across which, in the " in-tune " condition, is in quadrature with a voltage between the mid-point B of the circuit AC and the mid-point E of the load impedance of the rectifiers D, a voltage swing over the range of operation of at least 180 degrees is obtained between the paths AB and CD by coupling the resonant circuit AB and the corresponding tuned circuit of the receiver by at least one further tuned circuit and providing a feed back path between the discriminator and the tuned receiver circuit. There are thus obtained two frequencies corresponding to points 7, 8 on the control voltage curve, Fig. 1, besides the " intune" point 3 at which the voltages are in quadrature and the range of the automatic control is thus predetermined. In Fig. 5, circuit 4, 5, 6 is interposed between the I.F. stage 1, 2, 3 and the discriminator 7, 9 10 and this latter is coupled to the I.F. stage by a tuned circuit 13 and valve 12. In Fig. 6 a band-pass circuit 3 is used and coils 15, 16 tuned above and below the I.F. are provided in the cathode leg of the I.F. valve 2 to the grid of which the discriminator is coupled capacitatively by a condenser 18. In a similar circuit, Fig. 7 (not shown), the discriminator is connected directly to the cathode of the valve 2. Improved characteristic, of the control voltage curve is obtained by applying reaction to one or other of the tuned resonant circuits, Figs. 16 and 17 (not shown).

Title: Improvements in combination locks
IPC: E05B37/10
Filed: 1938-09-21
Abstract: 499,483. Permutation locks. MARTINS, P. Sept. 21, 1938, No. 27519. [Class 44] In a permutation lock having a tumbler 12 resting against the edges of discs 4, whose notches 6 are alignable, by the rotation of a knob, to enable the tumbler to be introduced therein to release the bolt, the tumbler is in the form of a spring held against the discs by its own resiliency. When the kink 13 in the tumbler enters the notches 6 to allow the end 14 of the tumbler to spring out of the notch 11 in the bolt 9, the bolt is retracted by a spring 10. Before the tumbler can re-engage the bolt, the combination must be scattered and to enable this to be done by a partial turn of the knob, the tumbler 12 is movable longitudinally by virtue of the resiliency of the part 16. One disc 4 is fixed to the knob spindle 2 and, when the knob is turned, this disc moves the tumbler, which carries with it the other discs until the kink 13 slips out of the notches 6. Brake blocks 7, pressed against the edges of the discs by a spring 8, prevent accidental rotation of the tumblers. In a modification, the tumbler is not free to move longitudinally and when the knob is turned to displace the kink 13 from the notches 6, the loose discs are not scattered. In a further modification, one end of the tumbler is again fixed, but disc-scattering is effected by mounting a brake block on an extension of the end 14 of the tumbler instead of on a separate spring, so that when the kink 13 is disengaged from the notches 6 by turning the disc fixed to the knob spindle, the other discs are scattered by the consequent movement of the brake block.

Abstract: 503,793. Fluid - actuated valves. NICOSTAT PRODUCTS, Inc. Oct. 13, 1937, No. 27895. Convention date, July 2: [Class 135] In a fluid-flow control device comprising a main valve 25 of disc form freely floating in a valve chamber 24 under the control of an auxiliary valve 38, the main valve is made so light in comparison with the fluid pressure forces acting on it that the device can operate in any position, and the auxiliary valve 38 is arranged in a chamber 36 which is always in free communication with the chamber 24 irrespective of the position of the valve 38. As shown in Figs. 1, 2 and 5, an inlet chamber 20 is separated from an outlet chamber 16 by a circular wall 17 on which the valve seat 18 is formed. When the valve 25 is fully open, the downward rush of fluid into the outlet creates a vacuum force tending to balance the dynamic fluid forces tending to open the valve. The chamber 36 is formed as an elongated recess in a cover 30 for connection to a port 40 leading to the outlet. The port 40 is controlled by the valve 38 which is pivotally engaged by forked fingers 44 on a counterbalanced lever 41 secured to a spindle 42 which passes out of the cover for connection by means of a cranked portion 50, 52 with the outer end of a bi-metallic spiral 56. The inner end of the spiral is connected to a finger 60 projecting from an arm 62 pivoted coaxially with the spindle 42 and adjusted by a cam portion 78 on a lever 71, a spring 80 maintaining the cam and arm in contact. The arm 62 and a back plate 67 on which the lever 71 is pivoted by means of a pin 76 are mounted on a boss 66 on the cover 30. The setting lever 71 cooperates with indications on a housing 92 supported by a flange 94 on the back plate 67.
