Title: Apparatus for vapour-conditioning grain
IPC: B02B1/08
Filed: 1940-01-29
Abstract: 540,679. Conditioning grain. FORSTER, jun., T. E. Jan. 29, 1940, No. 1778. [Class 58] [Also in Group XIII] In an apparatus for conditioning grain with steam comprising a horizontal cylinder 10 through which the grain is passed and to which steam is supplied from an inlet pipe 40 having a control valve 51, the quantity of steam admitted to the cylinder is controlled by a differential temperature responsive regulator 41 by which the valve 51 is actuated, the regulator having a "hot" bulb 43 in the grain outlet 17 and a "cold" bulb 42 in the grain inlet 16 of the cylinder 10. The regulator is set so as to give the increase in temperature of the grain, as recorded by thermometers 45, 44 in the grain outlet and inlet respectively, which corresponds with the desired weight of moisture absorbed by the grain. Thus in the case of wheat, a 20‹F. rise in temperature corresponds to a water absorption of 1 per cent. of its weight. The grain falls from the outlet 17 to a second cylinder 11, to which water may be admitted from a supply pipe 46, and from thence to a cooling cylinder 12 the lower side of which is in the form of a screen 36 and through which cooling air is drawn from a valve controlled inlet 38 by an exhausting fan 39. Cooling water is supplied to the shoot 18 through a valve controlled pipe 47; this admission of water to the cylinders 11 and 12 allows for the loss of, moisture during cooling. Beeswing &c. falls through the screen 36 into a hopper 37 and the conditioned grain is finally discharged through a shoot 19. The cylinders are provided with rotating axial shafts carrying lifting and dropping cups 33 .. 35 to agitate the grain, inlet tubes fitted with feeding worms 30 .. 32 on extensions of the axial shafts, and transverse adjustably mounted gates 20 .. 22 across their discharge ends to retain a predetermined quantity of grain in the cylinders. The regulator preferably comprises a double bellows type, the space 59 between the bellows 57, 58, Fig. 6, being connected through, a U-tube 61 and tube 60 to the "cold" bulb 42, and the space 62 between the outer bellows and its casing 54 being connected through a tube 55 to the "hot" bulb 43; these spaces contain suitable expansible liquids. The inner side of the bellows is closed by a plate 56 joined.at its edge to the casing 54, and the outer side of the bellows is closed by a head 53 carried by an extension 52 of the valve stem 51. A spring 63 with an adjusting nut 64 enable the regulator to be set. Specification 540,716 is referred to.

Abstract: 415,113. Discharge lamps. ROTHER, F., 6, Bozenerstrasse, Sch÷neberg, Berlin. Jan. 19, 1933, No. 1834. Convention date, Jan. 19, 1932. [Class 39 (i).] A lamp is provided with visible electrodes 2, 3 which are not heated by means of an auxiliary current source and are in the form of parallel wires or the like, which at one end are connected to contacts in the lamp cap 7, and the other ends of which are insulated from each other, e.g. by means of a glass bridge 4. Further, the filling consists of a gas or a vapour or a mixture thereof at a pressure of 6 mms. or less and of another gas or vapour or mixture thereof at a pressure greater than 6 mms., and the partial pressures of the two components are relatively adjusted so that the former component emits a column of brilliant radiation in one colour between or around the electrodes and the latter component covers one or both of the electrodes with a brilliant radiation in a different colour. The respective partial pressures may be 10 to 30 mms. and 2 to 4 mms. and the filling may consist of a mixture of argon and neon, or may comprise mercury, or the former component may consist of nitrogen and argon at partial pressures of 12 mms., and the latter component of helium and hydrogen having equal partial pressures. If the distance between the electrodes is sufficiently small, the glow covering each electrode may form one aureole surrounding both electrodes. A clear or frosted bulb may be used and the electrodes may be shaped as signs &c. and consist of a radioactive metal or alloy such as molybdenum-thorium or of an alloy of chromium and nickel or of nickel and iron. They may consist of a metal, which, as described in Specification 415,111, is coated with another metal which in the periodic table lies on the left side of, or on the left side of and below the line containing, the core metal. With continuous-current only one electrode is covered with a glow. The Specification as open to inspection under Sect. 91 states also that the former component consists of nitrogen and argon at partial pressures of 4 mms., and that a straight wire electrode may be arranged perpendicularly to a plane containing a wire loop-shaped electrode and passing through, or terminating at, the centre thereof. This subject-matter does not appear in the Specification as accepted.

Abstract: 693,517. Locking nuts. AEROQUIP CORPORATION. Jan. 25, 1951 [Feb. 17, 1950], No. 1973/51. Class 89 (i) [Also in Group XXVIII] In a coupling, e.g. a pipe coupling, wherein a nut retained on a part 13 is screwed on to a part 2 and brought into automatic engagement with a locking device provided on the part 2 to prevent unintentional backward rotary movement of the nut due to vibration, the device comprises a ring 28 having circumferentially-arranged and closely-spaced pawl-teeth 20 so that a number of the teeth can simultaneously engage ratchet teeth 21 of the nut. The ring 28 may be connected by fingers 31 in axially-movable relationship with a ring 29, the rings being urged apart by a wavelike ring spring 30. The nut may comprise inner and outer parts 6, 7 connected by a quickaction screw-thread 22 of opposite hand to the screwthread 5 which engages that of the part 2, the part 7 having at one end the teeth 21 and at the other end a flange 26 axially-movable in an annular recess 24 of the part 7. Relative rotation of the parts 6, 7 causes the free end 27 of the part 7 to clear the teeth 21 and the flange 26 to abut a flange 25 of the part 7 so that the parts are locked together and then screwed as a unified structure on to the part 2. To effect uncoupling, rotation of the part in 7 the opposite direction causes the part to move axially relatively to the part 6 until the flange 26 abuts a flange 23 of the part 7 and the end 27 presses the teeth 20, 21 out of engagement whereby the two parts are then again constrained to rotate together. Specification 656,483 is referred to.

Title: Improvements in valved amplifying circuits
IPC: H03F1/50
Filed: 1933-01-21
Abstract: 397,759. Valve amplifying circuits. TELEVISION LABROATORIES, Ltd. and FARNSWORTH, P. T., 505, Crocker Building, San Francisco, U.S.A. Jan. 21, 1933, No. 2063. [Class 40 (v).] The potential variations of the output electrode 12 and the control electrode 9 of an amplifying-valve 6 are in the same sense, and a network 37 between the electrodes 9, 12 has an admittance of the same character as, and of correct magnitude to neutralize, a component of the admittance of the input circuit 31 .. 34. The valve works on the bottom bend of the part of the plate characteristic in which the current flows in the reverse direction to normal. At this point the secondary emission is proportional to the flow of primary electrons, and the reverse current through the plate resistance 16 therefore produces fluctuations of the plate potential which are in phase with fluctuations in the potential of the control grid. By correctly proportioning the admittance y<1>, Fig. 3, of the neutralizing network 37 relatively to the input admittance y to be neutralized, the voltage on the grid G due to the amplified voltage E on the plate D is made equal to the input voltage e, and the effective input admittance is then zero. The capacity 37 neutralizes the capacity 33 in the input circuit. In a second amplifying-valve 53 a capacity 61 and a resistance 62 in parallel, and in series with a blocking-condenser 59, neutralize the output capacity of the valve 6 and part of the conductances of resistances 16, 57. A tuned circuit 64, 66 in parallel with the plate resistance 63 has sufficiently high impedance at the frequency to which the circuit is tuned for its effect to be negligible, but at other frequencies it reduces the voltage amplification of the valve and thus upsets the neutralization.

Abstract: 1411473 Mixing liquids in proportions ALFA LAVAL AB 16 Jan 1973 [19 Jan 1972] 2294/73 Heading BIC  Apparatus for metering and mixing liquids comprises a metering means having inlet conduits for receiving liquids under pressure and outlet conduits leading to a common outlet for the liquid mixture and compensating means for maintaining a substantially constant flow in the common outlet, the compensating means comprising an inlet chamber connected to the inlet conduit of one liquid, an outlet chamber connected in the common outlet and a pressure responsive member between the two chambers and movable in response to differing pressure in the chambers to expel liquid from the outlet chamber into the outlet conduit by the pressure in the inlet chamber in response to a reduction of pressure in the outlet chamber. In an embodiment three liquids in containers 10, 20, 30 are pumped by centrifugal pumps 11, 21, 31 to valves 13, 23, 33 with the liquid from container 10 passing through the chamber 47 of the flow compensating device 40 on its way to valve 13. Each liquid is directed by its respective valve through one of two conduits 12a, 12b; 22a, 22b; 32a, 32b; to a metering cylinder 14, 24, 34 respectively. Each cylinder communicates with two conduits from the respective value and the pistons in the cylinders are coupled to a rod 41 pivoted at 42, the cylinders 24, 34 having their pistons adjustably coupled to the rod. The outlet conduits from the valves are connected to a common outlet 44 and in this is connected chamber 48 of the compensating device 40. The piston rod 54, common to all the pistons of the valves is driven by a piston 60 in a fluid cylinder 61 and supply to that cylinder is controlled by valve means 64 actuated by the rod 41. In operation liquids from the containers 10, 20, 30 are pumped into the valves which direct them through conduits 12a, 22a, 32a, into the cylinders 14, 24, 34 to move the piston 15, 25, 35 to the right in the Figure thus forcing measured quantities of liquids already in the cylinders 12b, 22b, 32b into the valves and out to the conduits 19, 29, 39, to a common conduit 44. When the rod 41 reaches the position 43 the valve means 64 causes pressure to be supplied to the cylinder 61 to move the valve pistons to the right, to direct the liquids from the containers through the conduits 12b, 22b, 32b to the cylinders. In the chamber 48 of the compensating means 40 there exists a varying pressure due to the mixed liquids flowing therethrough but a constant pressure exists in chamber 47. Thus when pressure in the chamber 48 decreases the piston 46 is forced upwardly to expel liquid in the chamber 48 into the outlet conduit of the chamber 48 and 50 to retain a substantially constant pressure therein.
