Title: Machine for forming cylindrical hollow bundles from mowed grasses, cereals or the like as a substitute for sheaves
IPC: A01D43/00
Filed: 1924-08-07
Abstract: 221,195. Pettersson, V. I. Aug. 29, 1923, [Convention date]. Reaping-machines; sheafing-apparatus.-Grass, cereals, or similar crops cut by an adjustable mowing device 12 are carried by a longitudinal conveyer 15 to a studded transverse conveyer 14 which turns the cut crop, heads foremost, to a curved guide 17. The turning action is assisted by a vertical transverse conveyer 16 arranged at the rear of the conveyer 14. The guide 17 directs the crop into the annular space 10 between an outer cylinder 2 carried in a main wheel 1 and an inner cylinder 9 supported on a central shaft 8. The wheel 1 is supported on rollers 4 carried by shafts 5 projecting from the main frame 6. Rams 18, moving round with the cylinders 2, 9, and actuated by a cam member 20 on the main frame, compress the crop in the, space 10, the movement of the crop causing the rotation of wheels 21 having teeth projecting through slots in the inner cylinder. This rotation forces a worm sleeve 22 along the shaft 8 until it engages a clutch member 23, the wheels 21 then being driven in a direction to brake the movement of the crop through the passage 10. The speed of rotation of the wheel 21 may be varied by change gear in the train through which the shaft 8 is driven from a shaft 35 actuated by a pinion 36 engaging an intarnal gear on the wheel 1. The outer cylinder extends beyond the inner one a distance slightly larger than the length of a completed cylinder of grain and is cut away to provide an ejection opening 53. A cylindrical sleeve 37, also provided with an ejection opening, is rotatably mounted upon the outer end of the cylinder 2 and normally rotates therewith, but is adapted to be engaged and maintained stationary by a stop 41 on a rockshaft 40 provided also with an arm carrying a roller 38 adapted to be engaged by the grain cylinder as it approaches the end of the cylinder 2. The sleeve is held stationary until its ejection opening and the corresponding opening in the rotating cylinder 2 come into registration when the completed cylinder of grain falls on the field. The rock-shaft 40 also throws out the clutch coupling the feeding and conveying mechanism to the shaft 35 during the discharge of the grain cylinder. In a modification, the feeding and conveying mechanism is run continuously, one grain cylinder being separated from the next by the automatic operation of knives. The bundles of grain may take other shapes, such as cones, and may be tied up by binding mechanism. In further modifications, the cut crop is directed head foremost to the guide 17 by two transverse conveyer members, the rear one moving more quickly than the other, or the crop is delivered by a transverse conveyer so that the heads fall on a conveyer while the stalks fall on a stationary plate. For convenience in travelling the machine may have displaceable wheels and the platform may fold up.

Title: Improvements in and relating to pure fluid systems
IPC: F15C1/14
Filed: 1964-05-07
Abstract: 1,064,173. Fluid regulation. R.E. BOWLES. May 7, 1964 [May 31, 1963], No.18982/64. Heading G3H. A pure fluid device for producing an output signal which corresponds approximately to the time differential of an input signal comprises, a nozzle 52 receiving the input through conduit 53, a flow divider 48 for dividing the input signal equally into passages 43, 47 communicating respectively via lines 30, 31 with nozzles 14, 15 of a comparator 10, and output channels 25, 26 separated by a flow divider 22. Line 30 has a restrictor 55 and line 31 has a restrictor 56 and a capacitor 57. When the input signal is constant, the flows from nozzles 14, 15 combine to form a stream that is divided equally into channels 25, 26. If the input signal is instantaneously increased and maintained at the new value, the stream issuing from nozzle 14 experiences the increase with little delay, but the capacitor serves to delay the transmission of the increase to nozzle 15. The stream from nozzle 15 is thus diverted to channel 26 along with a portion of the stream from nozzle 14, and the pressure difference between channels 25, 26 indicates the change in the value of the input signal. Since the input signal remains at its new value, the signal from nozzle 15 gradually increases until it equals the signal from nozzle 14, at which stage the outputs from channels 25, 26 again become equal. A similar action occurs when the input signal is instantaneously reduced to its original value, except that the pressure difference between channels 25, 26 is in the opposite sense. In the alternative embodiment of Fig. 6 (not shown), nozzles 14, 15 are replaced by nozzles (67, 68) which control the deflection of a power jet from nozzle (63) into output channels (70, 71).

Title: Improvements in or relating to tobacco manipulating machines
Inventor: MOLINS DESMOND WALTER
IPC: A24C5/34
Filed: 1959-06-03
Abstract: 958, 021. Measuring electrically. MOLINS MACHINE CO. Ltd. June 2, 1960 [June 3, 1959], No.19064/59. Heading G1N. Variations in the uniformity of a continuous layer of tobacco, e.g. in a continuous rod cigarettemaking machine, are detected by passing air through the tobacco and over an electrical element, one of whose characteristics, e.g. resistance, varies with temperature. A perforated conveyer belt 2 passes through a chamber 3 adjacent the end of a narrow passage 1. Air is continuously drawn out of chamber 3 so that when a stream of air and cut tobacco is passed through passage 1 the tobacco forms a layer held by suction on the under-side of belt 2. The belt then passes under a chamber 6 containing a hot wire resistance element 50 (of tungsten) and air is drawn through the tobacco layer and conveyer belt over this element. As the air-permeability of the tobacco layer varies so the airflow over element 50 varies, causing a corresponding variation in its resistance. Element 50 is connected in series with a regulated power supply unit 53 and a load resistor 58, and a reference standard 54 sensitive to the ambient temperature compensates for changes in the temperature of the airstream over element 50. Across resistor 58 is connected aD.C. amplifier which feeds a positional solenoid 64. Armature 65 operates the input member 10 of a hydraulic amplifier 11 whose output member 13 operates trimming discs 5 which remove excess tobacco from the belt. Specification 929,338 is referred to.

Title: A manufacture of a monooxychrysene
IPC: C07C37/05
Filed: 1934-06-28
Abstract: Monooxychrysene is obtained by heating with a dilute acid the monoaminochrysene obtainable by mononitrating chrysene and reducing the nitro-compound thus formed.  Alternatively, a salt of the aminochrysene may be heated with water.  The dilute acid may be inorganic or organic such as sulphuric, hydrochloric, formic, acetic, benzenesulphonic, naphthalenesulphonic or benzoic acids. In examples, monoaminochrysene is heated with dilute sulphuric, sulphurous, hydrochloric or acetic acid, or the hydrochloride of monoaminochrysene is heated with water to yield a product that will couple with diazo-compounds.  Mononitrochrysene is prepared by nitrating chrysene with nitric acid and glacial acetic acid. Monoaminochrysene is prepared by reducing mononitrochrysene in the presence of glacial acetic acid with tin and hydrochloric acid.  The Specification as open to inspection under Sect. 91 refers also to the use of a mixture of sodium sulphate and dilute acetic acid in place of the dilute acid.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to high-frequency travelling-wave electron tubes
IPC: H01J23/30
Filed: 1954-06-30
Abstract: 778,399. Travelling wave tubes. RAYTHEON MANUFACTURING CO. June 30, 1954 [Oct. 27, 1953], No. 19208/54. Class 39(1). [Also in Group XL(b)] In a travelling wave tube the delay line has loss material only in a prescribed portion thereof, the characteristic impedance of the delay line being less in this prescribed portion than elsewhere. The loss material is a coating of ferromagnetic material, preferably iron, formed by electro-plating. In one form copper fingers 16, Fig. 1, carried by supports 15, forming parts of an interdigital line, are immersed in a plating bath containing an aqueous solution of 67 gms. of FeCl2 4H2O and 60 gms. of anhydrous CaCl2 and water to one litre and form the negative electrode, the positive electrode being of iron. The parts not to be coated are kept out of the solution or precoated to prevent deposition thereon. The characteristic impedance of the delay line is reduced in the vicinity of the loss material. to increase the absorption of the wave, by reducing the finger spacing in this region 33, and to avoid discontinuities transition section 35 has varying finger spacing and its fingers are also coated with lossy material. The spacing variations are produced by varying the thickness of the fingers, as shown, and/or the pitch distance of the line. The length of the fingers can be varied as shown in Fig. 1 to obtain desired attenuation characteristic. The finger length is about <#>/4 and the finger spacing is approximately equal to the space between their free ends and the opposite support 15. The tube shown is a backward wave oscillator operating with crossed electric and magnetic fields. Output is taken by a coaxial line adjacent the cathode, the inner conductor of the line being attached to an end finger of the delay-line and the vacuum being maintained by a ceramic seal in the coaxial line. A second coaxial line may be provided at the lossy end of the delay line to measure the reflected energy. The interdigitated line may be replaced by a helix or strapped or unstrapped multicavity line. The invention may be applied to travelling wave tubes not having transverse magnetic fields. In a crossed field backward wave oscillator of circular type, Fig. 3, with interdigital line comprising fingers 38 and support rings 39, block 40 decouples the ends of the delay-line and projection 41 collects electrons. The negative electrode 45 is secured by web 46 to cylinder 47 carried from the envelope end plate (not shown). The ribbon cathode 48 is carried by supports 49 urged apart by spring 49a. Supports 49 are connected via insulating supports 50 to projections 51 attached to negative electrode 45. The cathode leads, one of which is shown at 52, are connected to coaxial tubes 53, 54. The amount of loss can be estimated by applying an input signal to 42 and measuring the output from a coupling device at the other end of the delay line. Prior art devices in which loss material is applied by painting or spraying are referred to.

Filed: 1961-05-29
Abstract: 931,372. Cold separation of gas mixtures. UNION CARBIDE CORPORATION. May 29, 1961 [May 31, 1960], No. 19223/61. Class 8(2). In a compressed gas mixture e.g., air rectification process wherein a separated gaseous component e.g., nitrogen is used to cool feed air in heat exchangers 11, 18, 19, Fig. 1, and a product liquid oxygen is withdrawn from a conventional double column 23, 25 through a valved duct 41, at least a portion of the sowarmed gaseous nitrogen is liquefied in an externally refrigerated vessel 44 and is returned to the column 25 through a duct 45 in sufficient quantity to compensate for the cold lost by the column by the withdrawal of the liquid oxygen product. In operation a portion of feed air having traversed cooler 11 and an ammoniacooled exchanger 12 is expanded in a turbine 16 and is fed to a scrubber 17 where it is joined by the remaining air having traversed nitrogen-cooled exchangers 18, 19 and an expansion valve 20. Cleaned air then passes through a duct 22 to the high pressure column 23 whereas the contaminated scrubber liquid traverses one or other of filters 35 and passes to the low pressure column 25 together with oxygen-rid liquid from the base of column 23. Liquid nitrogen collecting on a sheet 28 of column 23 is further cooled in an exchanger 38 traversed by counterflowing effluent nitrogen from the head of column 25 after which a portion is expanded through a valve 39 into the column 25 as reflux whilst the remainder is flashed through a valve 47a into a pot 48 and the nitrogen vapour therefrom is added to the nitrogen effluent in duct 40. In a modification for the production of gaseous oxygen the latter is withdrawn from column 78, Fig. 2, through a duet 100 and after traversing a non-reversing path 64 in countercurrent to incoming feed air in an exchanger 61 is in part discharged through an outlet 102 and the remainder is fed through a duct 105 to a liquefying chamber 44 and the so-liquefied oxygen is fed through a duct 106 to the base of column 78 to compensate for the cold losses therein due to withdrawal of cold separated components therefrom. The feed air is also cooled by reverse flowing nitrogen in one or other of switchable paths 62, 63 which has a side bleed 65 from which condensible impurities are removed by traps 68 and residual impurities are removed from the main air stream by a trap 72. An additional adsorber 94 is located above the liquid oxygen in the base of column 78. In a further modification for the production of gaseous and liquid oxygen and liquid nitrogen the latter is obtained by liquefying warm effluent nitrogen leaving the heat exchanger in which feed air is cooled using an external refrigerant. Specification 931,371 is referred to.

IPC: D06M15/423
Filed: 1957-06-19
Abstract: Fabrics containing at least 50% of cellulose are impregnated with a reaction product of at least 2.5 mols. of formaldehyde, 1 mol. of urea and at least 1 mol. of glyoxal and are heated in the presence of an acid catalyst.  The molecular proportion of formaldehyde to urea may be as much as 4 to 1.  The urea and formaldehyde may be reacted first and the product reacted with the glyoxal or the monourein formed by reacting urea and glyoxal (from which glyoxal diurein and impurities have been removed) may be reacted with formaldehyde, or the components may be reacted together simultaneously.  The impregnating liquor may have a pH of 6 to 8.  Catalysts specified are tartaric and boric acids and magnesium and ammonium di-hydrogen phosphates.  The resin may be formed in an atmosphere of superheated steam or the fabric may be treated with steam after resin formation. The fabric may be embossed, glazed, creased or otherwise mechanically treated before forming the resin.  The fabric may be composed wholly or partly of cotton, linen or regenerated cellulose and may be subjected subsequently to a swelling or shrinking treatment with caustic soda, as described in Specification 437,361, and may then be further treated with a resin, which may also be a resin from at least 2.5 mols. of formaldehyde, 1 mol. of urea and at least 1 mol. of glyoxal.  In Example (3) (B), a stearamidomethylol melamine softener is added to the treating solution. Specification 744,991 also is referred to.ALSO:A resin (formed in situ upon cellulosic textiles) is formed from at least 2.5 mols. of formaldehyde, 1 mol. of urea and at least 1 mol. of glyoxal.  Resin formation is promoted by heating in the presence of an acid catalyst, tartaric and boric acids and ammonium and magnesium di-hydrogen phosphates being specified. Textile impregnating solutions have a pH of 6 to 8 and may comprise a reaction product formed by reacting the components simultaneously, or by first reacting the urea with the formaldehyde and subsequently reacting the product with glyoxal or by reacting the monourein obtained from urea and glyoxal (from which glyoxal diurein and other impurities are removed) with formaldehyde.  Molecular proportions of up to 4 of formaldehyde to 1 of each of the other components are specified.  The examples describe the formation of resin-containing impregnating solutions. In Example (5) a crystallized glyoxal monourein having a melting point of 146 DEG  C. is obtained from glyoxal and urea and is dissolved in a formaldehyde solution to which calcium hydroxide is added to give a pH of 8.3.  After standing, calcium is precipitated by adding oxalic acid until a pH of 7 is obtained. The solution is then warmed to precipitate calcium oxalate and magnesium dihydrogen phosphate (catalyst) is added to provide a textile treating solution.
