Title: Pulveriser
IPC: B02C19/06
Filed: 1936-12-19
Abstract: 469,068. Jet pulverizers ; endlesschain conveyers. GRAEMIGER, B. Dec. 19, 1936, No. 34977. Convention date, Dec. 21, 1935. [Class 59] [Also in Group XXX] In a jet pulverizer the nozzle or nozzles for the gas stream which lead into the periphery of the pulverizing chamber are located substantially tangentially to the wall of the pulverizing chamber, and the supply means for the raw material lead to the middle of the pulverizing chamber. As shown in Fig. 3 an air jet through nozzle or nozzles 23 circulates around a circular or polygonal chamber 20 which may have pins inserted through the walls or contain balls Material is fed to the centre of the chamber which may contain a fixed or movable conical member 37 and around which the material is displaced so that it is entrained by the air and projected onto the wall of the chamber either to be broken at impact or disintegrated in the subsequent frictional contact with the walls. The disintegrated material is carried up by the air blast through an annular orifice 26 into the outer chamber 29 of a separator 27. After passing through adjustable vanes 44 the material separated out falls into the inner chamber 30 and the fines ascend through divergent outlet 45. A central pipe 31 conveys fresh feed from a bunker 36 to the side of the chamber 30 from which it is fed into the pulverizing chamber 20 together with the coarse material separated out. The central feed pipe 31 may pass outside the chamber 30 so that the material separated out is kept separate from the fresh feed. The vanes 44 may be dispensed with and the outlet 45 may be made adjustable. In Fig. 9 the fresh material is supplied to a central hole in the bottom of the chamber 20 by means of a chain conveyer 104 supplied with material from a hopper 101, the upper and lower runs of the conveyer being separated by a partition bulged at 108 to raise material into the pulverizing chamber 20. The coarse material separated out in the chamber 30 of the separator 27 falls down onto the conveyer and is carried forward over the end 109 onto the lower run of the conveyer by which it is raised over the upturned end 112 of the partition and is carried into the hopper 101 by the upper run of the convever. The amount of material drawn from the hopper 101 is thus regulated according to the amount of returned material already in the conveyer and an automatic regulation of feed is effected. The size of the inlet end of the nozzle 23, Fig. 3, may be regulated by an adjustable hinged flap or by a sliding wedge-shaped member. Fig. 8 shows an arrangement of two pulverizing chambers 90, 96 in series, the material disintegrated in the chamber 90 by the jet 97 passing through an annular orifice 93 and impinging on an impact plate 95 before being engaged by the air jet entering through nozzle 98, the ground material being discharged through orifice 99. The outlet from the mill may be regulated by an iris diaphragm and-recesses may be made in the pulverizing chamber to receive tramp iron.

Title: An improved process for the recovery of pectic products from vegetable matter
Inventor: WALSH CONRAD LAWRENCE
IPC: C08B37/06
Filed: 1947-12-31
Abstract: Pectic substances are recovered from vegetable matter by treating it with a salt of an alkali metal or ammonia to produce a solution of a salt of the pectic substances from which a pectic acid gel containing 70-80 per cent of water is precipitated by the addition of acid, an oxide, hydroxide, carbonate, or bicarbonate of an alkali metal, alkaline earth metal or magnesium or a carbonate or bicarbonate of ammonium in finely-divided solid form or as a saturated aqueous solution or suspension being then mixed in to produce a salt which is subsequently dried and ground.  The vegetable matter may be parts or the whole of the plants, which may have been previously treated for the removal of fibre, wax, chlorophyll, alkaloid, hydroxy acid, glucoside, sugar, saponin, or other constituents.  This is treated with a solution of an alkali metal or ammonium bicarbonate, carbonate, sulphite, phosphate, or oxalate, preferably a 0.7 per cent solution of sodium carbonate.  The liquid is filtered through a stainless steel screen, the residue being pressed and the liquid being filtered and added to the main body.  A solution of a mineral acid, e.g. hydrochloric or sulphuric acid, in sufficient quantity to produce a pH of 4-2.5, is added and the precipitated pectic acid gel is recovered by filtering through a stainless steel screen.  The gel may be bleached by treatment with sodium hypochlorite and washed, re-screened, and subjected to pressure in a hydraulic press to reduce the water-content to approximately 80 per cent.  The gel is then mixed with finely-divided crystals or a saturated aqueous solution or suspension of the selected compound, and after the reaction is complete, the product is dried at about 70 DEG  C.

Title: Amusement vehicle for ghost railways
IPC: A63G5/00
Filed: 1937-12-20
Abstract: 499,431. Amusement vehicles. BEIER. N. T. Dec. 20, 1937, No. 35266. [Class 132 (i)] An amusement vehicle for ghost railways consists of an underframe 13 and a rotary body 21 disposed thereon characterized in that a steering wheel 24 is provided by which the passengers can rotate the body 21 relatively to the underframe 13. A rotary platform 20 may be disposed between the two so that the body 21 can be rotated relatively to the platform 20 by means of the steering wheel 24 through a chain 25 and roller 26, or in a modification through a friction clutch 37, Fig. 3, universal joint 35, pulley 32, rope 31 and pulley 30. The underframe 13 carries a caster wheel 14 running on a rail 12 and is driven through a pair of wheels 15 rolling on the floor 11, by means of an electric motor 18 situated in a cylindrical housing 17 which forms the pivot pin of the platform 20 and body 21. The platform 20, or in the platformless construction, the body 21 carries pins 27 so disposed that when the vehicle moves, they strike fixed stops 28 which rotate the body, the passenger returning the body to its normal position by the wheel 24. Anti-friction devices are fitted between the body, platform and frame, but brake blocks may also be fitted to subdue the swinging. In a modification, the caster wheel 14 is replaced by a plate 38 supporting two U-shaped irons carrying rollers 42 which bear on either side of the rail 12, with a wheel 14 on the rail. The stops 28 may be replaced by brake blocks on the walls at the height of the platform or the base of the body. In a further modification, the platform 20 is carried on caster wheels running on the floor 11 so relieving the underframe 13 of weight. These casters are connected to the platform 20 by springs or by a friction device so that when the underframe turns a sharp curve, the platform is rotated relatively to tbe underframe.

Title: Improvements in or relating to dynamo electric machines
IPC: H02K47/16
Filed: 1927-12-30
Abstract: 282,828. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Dec. 30, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Rotary transformers; windings; exciting; commutating windings. - A continuous-current dynamo-electric machine having two separate commutator windings or a single armature is provided with main and regulating field poles, in such a manner that the voltage in the brush axis of one commutator is due to the sum of the main and regulating fluxes, and in the other brush axis to the difference, so that the ratio of the commutator voltages may be varied. A rotary transformer, Figs. 1 and 2, has main poles N, S carrying a winding a connected across the supply mains and a compounding winding b, and regulating poles N<1>, S<1> having a winding c with a variable resistance d in series. The voltage across the motor brushes m<1>, m<2> is proportional to the difference of the main and regulating fluxes whereas the voltage across the generator brushes g<1>, g<2> is proportional to the sum. To obtain a greater range of secondary voltage regulation, for example, in starting railway motors, the current through the winding c may be reversible. If it is desired to compensate for the secondary voltage drop the regulating pole winding may be connected in series with the secondary load. Alternatively if a constant secondary voltage is required with a fluctuating supply voltage, for example for lighting systems or railway installations, the winding on the regulating poles may be connected across the supply mains or across the motor brushes. In this case the auxiliary poles are given a polarity opposite to that shown in Fig. 1, and are only slightly saturated whereas the main poles are highly saturated. The machine may be used as a threewire generator or as a balancing transformer in a three-wire system, the regulating pole winding being in series with the middle wire. If the main and regulating poles are located in axially displaced planes, the armature coils of both windings are bent as shown in Fig. 7, or, as shown in Fig. 8, the coils of one winding are twisted in the form of the numeral 8. Commutating poles may be employed excited partly from the. load current and partly from the current in the regulating pole winding.

Title: An improved process for removing bismuth from copper mattes
IPC: C22B15/00
Filed: 1935-12-23
Abstract: Bismuth is removed, during the working up of copper mattes to metallic copper by a blowing operation carried out on the molten matte in the presence of silica, by using finely divided silica in p excess of that required to slack impurities, such as iron, the presence of free silica being maintained at every stage of the process from the commencement to the end of the blow.  The silica may be added in a single charge before blowing or in successive portions, e.g. by blowing in with the blast.  Coal or carbon may be mixed with the silica; also a small amount of alkali sulphates or chlorides or lead may be added.  Instead of silica, substances containing free silica, silicates which have been opened up with sulphuric acid, ferrosilicon or substances which can form ferrosilicon as an intermediate product may be employed.  The resulting blister copper may be further refined with silica; lead may be added to the blister copper, silica and sodium sulphate or chloride or both being then blown in.

Title: Improvements relating to the removal of hydrogen sulphide
Inventor: NICKLIN THOMAS
IPC: C01B32/50
Filed: 1959-10-21
Abstract: <PICT:0871233/III/1> In a process for the absorption of H2S from gases or gaseous mixtures, the H2S is absorbed in an aqueous alkaline solution of one or more anthraquinone disulphonic acids whereby the hydrogen sulphide is oxidised to sulphur and the reduced anthraquinone disulphonic acid or acids is or are reoxidised by means of free oxygen or a gas containing it.  As shown, gases consisting of H2S or mixtures of H2S and other gases or gaseous mixtures, e.g. CO2, CO, H2, aliphatic or aromatic hydrocarbons, organic sulphur compounds, O2 and N2, say, coal gas, synthesis gas or natural gas, is passed through a plurality of series-connected scrubbing towers 1-4, preferably fabricated from iron-containing material e.g. mild steel, in counter-current to parallel streams of aqueous alkaline solution containing a mixture of isomeric anthraquinone disulphonic acids, particularly a mixture of the 1,5 and 1,8 or 2,6 and 2,7 isomers, containing sufficient alkali, e.g. caustic soda or potash, ammonia, sodium, potassium or ammonium carbonate or organic bases, e.g. alkanolamines, to produce a pH above 7. Spent solutions containing precipitated sulphur passes into tank D and thence by overflow to tank E.  From E the solution is passed by pump B to an oxidiser wherein it is contacted with a co-current of free oxygen or air to effect regeneration. Regenerated solution collects in tank C from whence it is passed to header tank F either directly, or wholly or in part through filter press G for removal of sulphur.  From header tank F solution is returned to the top of the absorption towers.  The process may be effected at normal or elevated temperatures and atmospheric or higher pressures.  When the gases contain CO2 at least part of the process is effected at elevated temperature to to produce a pH above 7.  Spent solution conbonate formation, e.g. the solution in tank F may be heated to expel CO2, or an additional heater (not shown) may be positioned between the washing and oxidation stages operating at 60 DEG C.  When the gases contain large amount of free oxygen the oxidation step may be omitted, the solution being returned direct to the top of the absorption towers after removal of sulphur. Reference is also made to the batchwise operation of the process, and to filtration before regeneration.  Where coal gas is scrubbed, the ammonia present in the gas may be sufficient for maintaining the pH.
