Title: Improvements in or relating to combine harvesters
IPC: A01D61/00
Filed: 1946-06-11
Abstract: 612,962. Combine harvesters. DEHN, S. G. (Minneapolis-Moline Power Implement Co.). June 11, 1946, No. 17485. [Class 6 (iii)] Relates to combine harvesters of the kind in which the sickle bar extends along the entire width of the machine. According to the invention, a conveyer 21a connects the harvester part A to the thresher part B, and a feeder assembly is disposed above the conveyer, a part of said feeder assembly being a crop engaging member D which positively engages the crop material during the downward and rearward rotation of a portion of the feeder assembly. In the construction shown, a reel 20 directs the crop to a sickle bar 19 and thence when cut to a pair of opposed augers 21 which convey the crop to the central longitudinally extending conveyer 21a, the crop cut along the whole width of the combine thereby passing to the thresher part B through a feeder housing C. The drum feeder device D (Fig. 3) in the housing comprises a shell 27 with end walls 29 from which trunnions extend to bearings in the side walls of the housing. A tubular shaft or pipe 44 is carried by arms 42 the stub shafts 40, 41 of which are mounted in the trunnions. A series of arms 47 are mounted on said pipe, all but one 47a (Fig. 3) of each series having a limited pivotal movement, the fixed one serving to rotate the shaft in unison with the drum. The arms all project through slots in the drum and since the axis of the drum is offset with respect to that of the shaft (which is fixed as arms 42 do not rotate) rotation of the drum and shaft causes the arms to project out to varying extents, the greatest being towards the auger side of the machine so that the crop is positively engaged and urged rearwardly and, as the arms retract, is not carried forwardly again.

Title: An improved apparatus for enabling a predetermined adjustable duration of illumination to be obtained in photographic printing processes
IPC: G03B27/16
Filed: 1922-06-27
Abstract: 190,440. Soc. Godefroy FrÞres. Dec. 14, 1921, [Convention date]. Printing-apparatus. - A dashpot timing-switch for regulating the duration of exposure, for example in bromide printing, comprises a driven member, retarded by brake action, and carrying an electrical contact adapted to move over a fixed contact of adjustable length to close the lighting circuit for a predetermined period. In the form shown, the movable member is a piston b movable, under the the action of a spring c, in a cylinder a filled with viscous liquid, such as glycerine or oil. Surrounding, and insulated from, the cylinder a is a rotatable cylinder k, having a helical upper edge, which may be set in any angular position with the aid of a scale on its base flange l. Pivoted to a collar f on the piston-rod d is a bent lever g, controlled by a spring j, and having a contact-finger i adapted to move against the surface of the cylinder k. The cylinders k and a carry the terminals p and q of the lighting circuit, and all the parts are of metal except the insulating washers o, r. In operation, the cylirder k is first rotated so that it presents the desired length of surface to the finger i, and the piston b is forced to the bottom of the cylinder a by pressure on a button h on the lever g, which simultaneously rotates this lever so that it does not make, contact with the cylinder k. The piston moves down freely owing to the opening of a ball valve m. On releasing the button h, the spring c forces the piston up, but the movement is retarded by the closing of the valve m, so that the liquid is forced to pass through the narrow space between the piston and the cylinder a. As the piston rises, the finger i, under the action of the spring j, engages and moves over the surface of the cylinder k, thus completing the lighting circuit for a period depending on the initial setting. A device is described for preventing the cylinder k during its adjustment from fouling the lever g.

Title: Mixing valve
IPC: F16K11/18
Filed: 1943-10-27
Abstract: 573,068. Mixing valves. JOHANSSON, F. A., and KALL, A. Oct. 27, 1943, No. 17728. [Class 135] In a mixing valve of the kind in which the quantity and ratio of the two fluids to be mixed are controlled by separate movements of the one operating element, and the hot and cold water inlets 3, 4, Fig. 1, are provided with stop valves 9, 10 actuated by a yoke 27 from the common operating member, the latter transmits longitudinal movement through a pin 40 to the yoke which is tiltably mounted with respect to the pin, and the ratio of mixing is controlled independently of the position of the pin either by a control member located after the stop valves or by relative movement of the latter. The operating handle 49 is in screwthreaded engagement with a non-rotatable pin 43 so that, as the handle is rotated, the pin 43 is withdrawn to allow the valves 9, 10, yoke 27 and pin 40 to be lifted by the pressure of the incoming liquids which will then flow through openings 18, 19, Fig. 2, in a partition 14, through a mixing chamber 24, and out through the spout 54. The openings 18, 19 are non- symmetrically placed in the partition, and they are obturated to vary the mixing ratio of the two liquids by means of heels 31, 32 depending from a member 30 which carries the handle 49 &c. and which can be rotated about the axis of the pin 40. A spring 37 presses the member 30 downwards. The valves 9, 10 carry positioning pins 7, 8, and they are in contact with the yoke 27 through the medium of pins 22, 23 which engage in recesses in the yoke. The pin 40 engages in a conical recess 29 in the yoke to allow the latter to tilt slightly. An indicator 52 is provided. In a modification, the yoke carries rollers acted upon by cam surfaces on the member 30 so that, as the latter is rotated, the ratio of the amounts of the two liquids entering the mixing chamber is varied both by the relative amount of opening the valves 9, 10 as well as by the relative restriction of the openings 18, 19. The recess 29 is elongated slightly in one direction to allow the yoke to tilt suitably. In a further modification, the pin 43, Fig. 14, carries a tongue engaging in a slot in the' pin 40 to prevent rotation of the pins, and the upper end of pin 43 has a ball and socket joint 63 with a screwed spindle 65 carried by the handle 49. The heels 31, 32 are omitted and the mixing ratio of the two liquids is controlled solely by the relative amounts of opening of the valves 9, 10. The latter carry projections 70, 71 on which are loosely threaded pins 22, 23 projecting through apertures in the yoke 27, and the upper ends of the pins are engaged by a cam face 72 on the member 30. The pin 40 seats in a depression in the yoke. To prevent the partition 14 from rotating, it carries depending flanges engaging in cut-away portions of the flange on which it is supported.

Title: Improvements in and relating to diesel and like internal combustion engines
IPC: F02B3/00
Filed: 1925-07-10
Abstract: 263,895. Bentley, H. July 10, 1925. Regulating.-In Diesel and like engines, a more constant ignition temperature arising from compression of the air charge is obtained by causing the inlet valve to remain open longer as the speed increases, so that a variable quantity of the air charge is driven out through the inlet valve according to the speed, the whole charge being retained at starting and low speeds. Fig. 3 shows a two-stroke engine having a pump piston 2<a> compressing air into a transfer passage or receiver 4 past a non-return valve 4<a>. This aic is admitted to the working cylinder through a valve 5 controlled bv a cam 7 which is movable axially by hand or governor to vary the time of closing of the valve. The invention may be applied to four-stroke engines. Specification 208,740 is referred to.

Abstract: 942,032. Transistor switching circuits. OLYMPIA WERKE A.G. May 9, 1962 [May 12, 1961], No. 17826/62. Heading H3T. [Also in Division G5] The ends 5, 6 of the winding of a head 4 are connected directly to the secondary 18 of a write transformer 3 and through pairs of complementary transistors 7, 9 and 8, 10 to the centre-tapped primary of a read transformer 14, the transistor bases being switched by flip-flop means, represented by the switch 33 to potentials which pass read but block write currents from the input stage of the read amplifier 13, one of the transistors of each series connected pair blocking positive voltages and the other the negative voltages. By virtue of the symmetry of the arrangement about the centre-taps 21, 22, any small standing direct currents in the half-windings 23, 24 which are cut off by the switch 33 during write, do not give rise to spurious read outputs. The waveforms arising are indicated (Fig. 3, not shown).

Filed: 1939-06-19
Abstract: 539,932. Ammonium nitrate. HYDRO NITRO SOC. ANON., and HOBLER, T. June 19, 1939, No. 17868. Convention date, June 27, 1938. [Class 1 (ii)] In a process for the production of ammonium nitrate of the kind in which the ammonium nitrate is concentrated in two stages (a) by circulation through an absorption unit in which the nitric acid is added at the point of greatest pressure in the circuit and in which concentration is effected by introduction of air (b) by further concentration under reduced pressure while being further heated by heat exchange with the solution under going preliminary concentration, the further concentration is effected while blowing air therethrough. The plant comprises a tower 50 having an absorption section 1 and evaporator 5, and a heat exchanger comprising outer and inner vessels forming an annular passage 3. The nitrate solution is pumped from the bottom of the tower 50 through line 36 by a pump 2 which forces it through the annular passage 3 and thence through line 40 and spray nozzle 4 back to the tower 50. Nitric acid from a tank 26 is pre-heated in coil 27 and then enters through line 18 the circuit at the point of greatest pressure, e.g. at the side of the pump 2. Ammonia is supplied through line 32 and air through line 38. A portion of the solution passing through the syphon 6 connecting the absorption and evaporation sections is withdrawn through line 12 and, mixed with sufficient solution from the sump 52 to give a neutral solution, is fed to a tank 14 divided into two sections so that tests for neutrality may be made. The withdrawn solution is further concentrated by pumping it through a line 18 to a weir 19 at the top of the heat exchanger from which the solution trickles down the inside of the concentrater 20 where it is concentrated by air injected through lines 33. The solution concentrated to 92-96 per cent. is withdrawn to a tank 22 provided with a jacket 24 connected to the jacket of the heat exchanger which may be heated with steam should a break in the circulation occur. German Specifications 539,642 and 614,324 are referred to.
