Title: Excavating machine
IPC: E02F3/48
Filed: 1926-06-23
Abstract: 280,980. Dunlop, G. H. June 23, 1926. Scraping-apparatus.- An excavator comprises a main frame with a swingable jib from which is suspended a. scoop operable by filling, hoisting and tipping ropes, a substantially rectangular braced frame at the front of the main frame and supporting a horizontal frame which provides an upper bearing for a rotatable jib post, a pivotally adjustable V-shaped roller frame supported on the braced frame, and means for restraining the swinging movements of the jib. In Figs. 1 and 2, a wheeled frame 32 carries forwardly a frame 9 internally braced and supported by stays 12, the side posts of the frame being vertical or inwardly inclined. A triangular frame 13<a> projects from the top of the frame 9 and provides an upper bearing for a rotatable jib post 8, arched at 8<a> and fixed to a bracket 1<b> in which the jib 1<a> is pivoted; an adjustable stay 8<b> supports the jib. while the jib post 8 carries a brake drum 14 by which it may be held against rotation. Jib ties 15 are attached to opposite sides of the brake drum which further carries a link 14b and pulley 16<b> for a jib tie 16. The scoop 1 is filled by hauling on a rope 2 passing over pulleys 6, 7 to a winding drum 2a; the pulley 6 may have a V- groove. The scoop is then lifted by a rope 3 passing over a jib pulley 3<b> and side pulley 5 to a winding drum 3<a>, the rope 3 also swinging the jib laterally. Tipping of the scoop, and return of the jib. are then effected by a rope 4 passing over pulleys 4<b>, 5<a>, to a winding drum 4a. The carriers of the pulleys 5, 5<a> are pivoted on vertical or inclined axes. A brake tie 17 is secured to the side of the brake drum remote from the pulley 5 to resist the pull of the rope 3 when the jib post is locked. A check tie 17<a> limits swing of the jib and preferably includes a spring. When the jib is in a sideward position, the rope 3 or 4 on the opposite side engages a forwardly projecting roller 12<a>, so exerting a greater leverage when returning the jib; the roller 12<a>, is carried by a frame 12b, pivoted at 12<c>, and held in adjusted position by a bolt and an apertured plate. The side pulleys 5, 5<a>, may have weighted or spring- actuated levers 29, Fig. 9, to hold the slack rope 3, 4 in position to engage the roller 12<a>. The winding drum 2<a> is driven through clutch 22 and slow gearing 19, 19<a>, and the winding drums 3a, 4<a>, through fast gearing 20, 20a, and separate clutches. In a modification, the winding drum 2a is provided with a clutch for connection to its shaft which is then arranged in front of, and driven from, the shaft carrying the winding drums 3<a>, 4a. In a further modification, the winding drums 2<a>, 3<a>, 4<a>, are carried by the front frame 9, the rope 2 then passing directly from the pulley 6 to its drum 2<a>. The side pulleys 5, 5<a>, may be replaced by flanged rollers 23, Fig. 8, supported on horizontal pins 25 and adjustably secured by slotted brackets 27 and nuts 28; guide rollers 23<a> may be provided.

Filed: 1968-04-03
Abstract: 1,220,465. Non-woven fabrics. PAPETERIES NAVARRE. 3 April, 1968 [4 April, 1967], No. 16073/68. Headings D1L and D1R. In a method of producing a fibrous structure from a crude base comprising intermingled fibres of at least two types one of which is retractile compared to the other type or types, the fibres are softened and the retractile fibres caused to shrink whilst the base is free to contract in at least one of its major dimensions and to expand in the direction of its thickness. The softening of the fibres is preferably effected by means of water vapour at a lower temperature than the shrinkage temperature of the retractile fibres. The shrinkage of the retractile fibres may be effected by the action of heat e.g. water vapour. A binder may be incorporated in the base prior to the softening step; the binder may be fibrous, natural, synthetic or artificial and in the form of an emulsion, solution or a powder. The binder may be stabilised after the shrinkage step. As shown, an enclosure F forms a softening and shrinking tunnel for a fibrous base 10 while supported by an endless conveyor belt 1. The tunnel may be divided into compartments each of which is supplied with gaseous fluid at different temperatures and humidity. The conveyor belt 1 which may be plastics sheet material or metal fabric preferably has an inclined upper run, the base 10 moving down the incline during its passage through the tunnel. The conveyor belt 1 may be supported by heated rotary bars within the tunnel, and nip rolls may be provided at the entrance and exit openings of the tunnel (Fig. 2).

IPC: B23P15/40
Filed: 1962-04-30
Abstract: 966,630. Making paper creasing dies; jointing. CONTAINER CORPORATION OF AMERICA. April 30, 1962, No. 16397/62. Headings B3A and B3V. [Also in Division B6] A method of assembling prefabricated scoring channels on a cutting jacket for the production of carboard carton blanks comprises assembling on the flat bed of the press a plurality of upstanding scoring rules, applying markings on the cutting jacket to indicate the lines of pressure to be applied by the scoring rules, releasably positioning the scoring channels on scoring rules, applying adhesive to an uppermost flat face of the scoring channels and to areas of the cutting jacket indicated by said markings, and moving the cutting jacket into pressure contact with the uppermost surfaces of the scoring channels to transfer said channels to the cutting jacket. The adhesive is allowed to dry beyond the tacky stage before assembly. As seen in Fig. 1, a press assembled according to the above method comprises the die 10 formed by locating a series of scoring rules 13 and cutting blades 14 in an assembly of wood blocks held within a steel frame co-operating with a platen in the form of a cylinder 11 on which is mounted a cutting jacket 17 to act as an anvil for the cutting knives 14 and a number of adhesively secured scoring channels 16 which may be made of brass, and which form score lines in the blank in association with the scoring rules 13. Fig. 5 shows one method of releasably mounting the scoring channels centrally on the scoring rules, the width between the channel sides 16a being greater than the scoring rule thickness by an amount equal to twice the blank thickness. A strip 20 of plastics or lead is interposed between the scoring rules and channels. A second method of centring the channels (Fig. 4, not shown) employs a rectangular bar of plastics material having in its lower face a groove of width corresponding to the scoring rule thickness, and on its uppermost face a rectangular key of width corresponding to the distance between the channel walls 16a. The guide lines for applying adhesive to the cutting jacket 17 may be formed by placing a sheet of carbon paper on the scoring and cutting rules 13, 14, placing a thin sheet such as paper on the carbon paper, pressing the paper, and adhesively securing the carbon marked sheet of paper to the cutting jacket 17 by aligning a given pair of lines at right-angles to each other on the paper with two corresponding lines already marked on the jacket. Alternatively, all the guide lines may be marked directly on the cutting jacket. Reference has been directed by the Comptroller to Specification 807,251.

Title: Improvements in coin testing apparatus for coin freed automatic sales apparatus
Filed: 1928-06-06
Abstract: 305,161. Eller, F. Feb.- 1, 1928, [Convention date]. Testing coins. - Coin-freed apparatus is provided with a shoot having a single slot for inserting coins of different denominations and equipped with an assorting passage and testing passages, the testing passages being provided with slots in their laterally inclined side walls of a height permitting coins of normal size to pass along the passage hut coins which are too small to drop through the slots. For assorting and testing coins of two different sizes, they are inserted through a slot a, Fig. 1, into a shoot d formed by two members b, c hinged together, the member c having a longitudinal slot comprising three sections f<1>, f<2>, f<3> of different breadth. Coins of less diameter than the smaller coin fall out through the section f<1>. The smaller coins fall through the section f<2> to a shoot g and the larger coins run through to a shoot k. Coins of less diameter than the larger coins run through the section f<3>. Coins that are too thin fall between the members b, c. Rejected coins are returned through a passage h to a tray i. In a modification, Fig. 3, the testing passages d<1>, d<2> for large and small coins respectively are arranged above each other. In front of the passage d<1> is a passage m communicating with a narrower passage n in front of the passage d<2>, so that there is a shoulder o between the parts m, n. A large coin of proper thickness runs on the shoulder o into the passage d'. If it is too small in diameter, it tilts through a slot p, and, if it is too thin, it drops past the shoulder o to the passage n, where it remains until the members b, c are opened by pressing a push button. The smaller coins drop through the passages m, n and roll along the passage d<2> which has a slot g for testing diameter. Too thin coins drop past a shoulder r at the bottom of the passage n and through a slot s to the reject shoot h. More than two sizes of coins may be tested by increasing the number of testing passages.

Title: Improvements in or relating to the concentration of minerals by froth flotation
IPC: B03D1/012
Filed: 1938-06-03
Abstract: 515,937. Concentrating minerals. MINERALS SEPARATION, Ltd. June 3, 1938, Nos. 16754 and 16755. Convention dates, June 5, 1937, and Dec. 18, 1937. [Class 82 (ii)] [Also in Group III] A xanthomolybdic acid compound is used as a collecting agent in the froth flotation concentration of minerals. The compound, which can be employed in conjunction with other collectors such as xanthates and dithiophosphates, is prepared by acidification of a solution of a xanthate and a molybdate, the preferred proportions corresponding to 2 molecules of xanthic acid to 1 of molybdic acid. The xanthomolybdic acid compound is precipitated as an oil which solidifies on standing ; it may be purified by solution in ammonia and reprecipitation with acid. The compound may be added in the solid form to the ore during grinding or to the pulp as a solution in an organic liquid such as acetone, chloroform, or ether, or the mixture obtained on acidification of the xanthate-molybdate solution may be added. The concentration of the following ores is described, a xanthomolybdic acid compound being used in each case in addition to the reagents specified :-(1) copper ores using pine oil and lime ; (2) lead ores using soda ash and cresol; zinc ores using copper sulphate and pine oil ; gold and silver ores using pine oil and cresol; molybdenum ore using sodium cyanide and terpineol. In the concentration of a copper-molybdenum ore a copper concentrate is first obtained by using cresol and xanthate with a depressing agent such as starch or other protective colloid to inhibit flotation of molybdenite ; the tailings are then subjected to flotation with pine oil and a xanthomolybdic acid compound to give molybdenite concentrate which is cleaned by refloating with cyanide and pine oil. In the treatment of mixed sulphideoxide copper ores the sulphides may be floated by the use of the xanthomolybdic acid compound and pine oil, the remaining pulp being thickened, leached with sulphuric acid to dissolve the oxide copper which is then precipitated as metallic copper by addition of iron and floated with pine oil, Barrett oil, and the xanthomolybdic acid compound. Alternative treatments comprise (a) removing the oxide copper by leaching and filtering prior to flotation, and (b) dissolving the oxide copper by treatment with sulphuric acid, precipitating by adding iron, and floating the sulphide copper and metallic copper together. Specification 223,860, [Class 82 (ii)] and U.S.A. specification 2,070,076, are referred to.
