Title: Improvements in and relating to pressure filter presses
IPC: B30B9/04
Filed: 1963-02-05
Abstract: 986,870. Pressure filter presses. STAHLWERKE SUDWESTFALEN A.G. Feb. 5, 1963 [Feb. 22, 1962], No. 4608/63. Heading BID. A rotary pressure filter is provided with a plurality of rotating disc filters which are arranged on a shaft parallel to one another and between which annular cyindrical filter chambers are arranged and communicate, on the inlet side, with a press chamber which is common to all filter chambers and is provided with a closable inlet for the material to be filtered and has a press piston by which the material to be filtered is compressed in the press chamber and in the filter chambers. As shown (Fig. 3), material to be filtered enters inlet 6 and passes into the press chamber 5, the piston 7 then closing the inlet. Under the action of the pistons 8, the material is forced into the annular filter chambers 13, between oposed pairs of revolving filter wheels 4, and the solid concentrate is carried along a circular path towards the discharge outlets 27, Figs. I and 2, so that there forms in front of the slide 28, a solid plug of material. Slide 28 is then opened, the plug sealing the discharge outlet, and during the withdrawal stroke of the pistons 8, fresh material is introduced via inlet 6. The filter wheels 4 each consist of two half discs 14, mounted on the shaft 3, having circumferential rubber sealing rings 15 resting against the wall of the cylindrical shell 1, and are each fitted with a perforated screen 16, Figs. 4 and 5, in close contact with a helical wire spiral spring 18 of round cross-section, Fig. 7, which acts as an edge-filter. In Fig. 6, an additional perforated screen 17 abuts the other side of the spiral. Hence liquid passes through the spiral 18 and screen 16 (or screen 17, spiral 18 and screen 16) of the filter wheel 4 and through the ducts 22 and 23 to openings 24 in the shell of the cylindrical housing 1 which communicates therewith during each revolution of the filter wheels and filtrate flows from outlet 25 into the discharge duct 26. The inlets 12 and outlets 27 are placed as close as possible so that as large a part of the circumference of the cylinder as possible is available for the removal of liquid. The narrow zone between the inlet and outlet, Fig. 1, in which no filtration takes place, may be utilized for the removal of solids, by the action of steel rods (not shown) arranged in this zone to clean the spiral spring filter linings or the surfaces of the perforated screens. In a modification (not shown) only one pair of filter wheels is used, and the covers 2 of the cylinder 1 are replaced by press pistons, moving in opposite directions along the axis of the cylinder 1, thus forming two filter chambers. In this modification the press pistons 8 and cylinders 10 are replaced by the cylinder shell. Chamber widths of 50-80 mm. and operating pressures of 470-1420 p.s.i. are specified. Such presses may be used in conjunction with pneumatic and hydraulic conveyers for concentrating the solids-liquid mixture flowing therethrough.

Filed: 1916-03-29
Abstract: 100,304. National Equipment Co., (Assignees of Bausman, A. L.). April 17, 1915, [Convention date]. Depositing-machines. - Relates to so-called " starch " machines in which the starch is used as a moulding-material for candy centres or cores, and consists in an arrangement in which loaded draws may be placed and emptied, and in which empty trays may be placed to be filled and levelled with starch in a semi-automatic manner, thereby providing a machine for use intermittently, and one which is of utility to t.he small manufacturer; provision is also made for the separation of the candy cores from the starch as well as for cleaning the cores in substantially the usual manner. A tray is placed on guides 105, 106 and pushed forwards until it engages a vertical web 108, and the operator then depresses a hand-lever 87, throwing in a clutch which rotates a shaft 80 and consequently a conveyer chain 101. A lug 100 on the chain engages the side of the tray and moves it along tracks 109. 110 into filling position over a starch receptacle 32, and at the same time a tray filled with starch is moved out of the machine on to a platform 111: during this movement, the surplus starch is automatically removed from the tray by a reciprocating leveller 115. The filled tray is then "printed" with recesses to receive the molten material for the cores, and after these cores have hardened, the loaded tray is inserted in a rack 38 at the top of the machine. Meanwhile, the conveyer chain 101 is stopped by the engagement of a second lug 100 on the chain with a trip 102 of a rod 98, which releases a lock holding the lever 87 in its depressed position, and the empty tray 33 is filled with starch from the receptacle 32. This filling- means is continuously running and comprises a screw conveyer 17 which feeds the starch to one end of the receptacle 32 into a position to be engaged by lifters 31 bridged across chains 23, 24. these lifters deposit the starch in the tray 33. Meanwhile, the tray in the rack 38 is inverted bv rotating a hand-lever 44, and the starch and cores fall on to an inclined vibrating sieve 45, through which most of the starch drops back into the receptacle 32. The cores work down and fall into a second and brush-lined sieve 57, where they are cleaned by brushes 61 carried by an oscillating frame 62. The starch and small pieces of core drop through the sieve 57 into a third sieve 74, which catches the pieces of core, but permits the starch to pass through on to deflecting-plates 75, 76 and so back to the receptacle 32. The cleaned cores pass along the portion 57<1> of the sieve 57 and fall into a receptacle placed on brackets 59<2>, while the core chips pass out of the machine through a delivery pipe.

Abstract: 895,476. Automatic control systems for power stations operating in parallel. GENERAL ELECTRIC CO. Feb. 10, 1960 [Feb. 12, 1959; April 30, 1959], No. 4672/60. Drawings to Specification. Class 38 (4). In an apparatus for computing the most economic method of generating and transferring power between a plurality of local transmission systems one of the local systems acts as a reference to which all the other local systems are compared, and a plurality of signals are generated, each representing the amount of power to be exchanged between each of the local systems and the reference system. The means at each local system has signals fed to it representative of the difference between power generated and power consumed, which means produces a signal representative of the incremental cost of power, the means being in two parts, which delivers a signal appropriate to whether power is to be imported or exported. The signals representative of the power to be exchanged to bring the system into economic balance may be relayed manually to each local system by a despatcher at the reference point, or by means of comparators having signals fed to them representative of the actual and most economic power generation, an error signal is derived which conrols the generated power in each local system automatically. The incremental cost signals may be modified to allow for the cost of transmission losses. Specification 866,271 is referred to.

Abstract: 1,261,073. Transformers. LINCOLN ELECTRIC CO. 30 Jan., 1969 [2 Feb., 1968], No. 5132/69. Heading H1T. The output voltage from a transformer with a shell-type core is adjustable in small increments by taps on a secondary winding on the centre leg, the taps being disposed on the end turn at least one tap being spaced less than one half-turn from an end tap and at least one connection to a tap passing outwards through a hole in the core. There may be taps on the second turn of said winding including a tap X2 at its end which is insulated from the tap E2 at the beginning of the third turn, all the taps may be connected to appropriate contacts on two selector switches SW1, SW2, whereby setting of the switches adjusts the voltage output of the winding in small increments. There may be secondary windings 1, 3 on the other legs 11, 13 of the core T and there may be coarse tappings A, B, C, D, E at 1 turn intervals along all the secondary windings connected to a terminal board S. In the case of a three-phase transformer the terminals may be so disposed that a single shorting plate P may connect the three windings in star connection thereby varying the output voltage of each winding in coarse steps while ensuring that the voltage output difference between any two windings is less than the volts per turn of the winding. The transformer output taps may be connected to the input terminals of a full-wave rectifier R and inclusion of the selector switches SW1, SW2 and terminal board S provides a D.C. voltage supply, the output voltage being adjustable in small increments over a large range, such a supply being suitable for welding apparatus.

Abstract: 818,176. Coated polyalkylene terephthalate films. KALLE & CO., A. G. Feb. 20, 1956 [Feb. 19, 1955], No. 5216/56. Class 140. Coated foils comprise a base foil of a high polymeric polyalkylene terephthalate, especially polyethylene terephthalate that has been stretched in two directions at right angles to at least twice its original dimensions and fixed in this condition by heating at 140-230 C., provided with an anchoring agent on one or both sides which is a difficultly volatile organic isocyanate, tri-N : N-ethyleneimino phosphine oxide or p-nitraniline, and a top coating layer consisting wholly or for the most part of polyethylene. The isocyanates which are used as anchoring agents are defined as including mono-, di- and polyisocyanates, also monomeric, dimeric and polymeric isocyanates and addition products of isocyanates with tertiary alcohols, ethyleneimine or acetamide which will reform isocyanates on heating. The coating composition may be wholly polyethylene or may contain polyisobutylene and may be applied as a melt or a solution in such solvents as trichloroethylene, chlorobenzene or xylene. In the construction of the coated foil it is necessary to apply heat at various stages. If tri - N : N - ethyleneimino - phosphine oxide is used as anchoring agent, the foil and anchor layer must be heated prior to coating with polyethylene, and always the final coated foil must be heated to provide firm adhesion between the layers, but in any of these operations the temperature at which heating is carried out must not exceed the temperature at which the base foil was fixed. The anchoring agent may be incorporated in the polyethylene coating composition and a preformed polyethylene foil may be secured to the polyethylene teraphthalate foil to form a laminated assembly.

[Class 138 (i)] Screen wiper operating mechanism comprises a crank actuating a spring-returned reciprocating member and means for arresting its movement; the arresting means may be provided with means for moving the arm to an unobtrusive position, or this may be effected by the further motion of the crank. As shown in Fig. 1, a rack a is reciprocated by a crank g engaging an open link h, and a spring j. The movement is arrested by a hand-operated spring pawl k, and the pawl may be moved to rotate the wiper arm to an unobstructive position by an eccentric o. Figs. 6 and 7 show a form in which this final movement is effected by the crank. For this purpose the crank g has parts of different diameters for engagement with wide and narrow parts i, i<SP>1</SP> of a slot in the member h, the normal movement taking place with the narrow part of the crank in the slot i<SP>1</SP>. On the movement of the rack being arrested the crank moves into the wider part of the slot and a spring r forces the wider diameter part of the crank into engagement therewith. The next movement of the crank effects the increased movement of the rack. The part h is returned to its normal position with the narrow part of the crank in engagement with the slot i<SP>1</SP> by the engagement of a projection t with an inclined abutment u. In another form, similar to Fig. 1, the gap i in which the crank works has a bight which is engaged by the crank, after the rack has been arrested, to effect the final movement of the rack. In a further form in which the rack is returned by a compression spring the crank operates a lever 2, Fig. 12, which engages the end of the rack, and the movement of the rack is effected by a handoperated detent 5 a notch 5b in which engages a projection 6 on the lever 2. The next operation of the crank engages a spring-influenced lever 7 on the lever 2 to provide the final movement of the rack.

Abstract: 433,629. Making pistons, bearings, crank shafts, and machine details. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Rose-Engle Co. ; 711, Sanford Street, Wilmington, California, U.S.A.) Feb. 19, 1934, No. 5391. [Class 83 (ii)] [See also Group II] A metallic band is inlaid in the surface of a metallic machine element, e.g. a piston, crank shaft, or bearing, by cutting a groove in the surface of the element by means of a cutting tool which is shaped or set so that it breaks the metal in the surface of the groove and leaves it abnormally rough and then depositing metal in the groove by a spraying process. The process is particularly applicable to inlaying a band of hard metal, e.g. steel, in a machine element made of a light alloy. A piston 1 held in lathe supports 2 is rotated in contact with a cutting tool which cuts a screw thread beneath the surface of the metal producing a wide groove with a serrated bottom 3, the tool being set so that it breaks the metal slightly leaving the surface of the groove abnormally rough. The sides of the wide groove are undercut at 4. A spraying pistol 5 is mounted on a post on a carriage which can be moved longitudinally with respect to the piston and the piston is rotated while the metal is sprayed into the groove. The deposited metal is then ground down to the required size. Specification 408,067 is referred to.
