Title: Improvements in mills for grinding grain and the like
IPC: B02C7/18
Filed: 1925-05-20
Abstract: 235,173. Bjerre, S. June 6, 1924, [Convention date]. Disc and like mills.-A machine of the kind in which the grain or other material to be ground is fed between two grinding-members one of which is normally stationary while the other rotates, is so arranged that the, normally stationary member moves axially relatively to the rotating member along a stationary shaft when an overload occurs on the machine to relieve the same, and moves back to its original position automatically when the overload ceases. At the same time the feed to the machine is reduced. The rotating member 2 is supported in bearings 12 around a stationary shaft 1 on which is slidably supported on collars 6, 7 the normally stationary member 3 and hub 5. A spring 14, compressed between the collar 7 and a nut 15 screwed on the shaft 1, maintains the grinding- members in contact. In the event of an overload, the increased frictional torque on the stationary grinding member turns it on its shaft 1 against the action of a spring attached to an arm 8 projecting from the hub 5 and anchored to the casing of the machine, and a screw 22, attached to the frame connecting the collars 6. 7, rides up an inclined surface on a nut 4 secured to the shaft 1 and on which the collar 6 rests, to separate the grinding-members. At the same time an arm attached to the hub 5 acts on the oscillating feed-tray 21 by which material fed into the hopper 19 is transferred to the grinding- members and moves it relatively to the cam 20 on the rotating shaft 41 by which it is oscillated to reduce or stop the feed. Instead of the spring referred to above, the spring 14 may be used to control the angular movement of the member 3 on the shaft 1.

Title: Method of welding thermoplastic organic film material
IPC: B32B27/00
Filed: 1964-03-31
Abstract: 1,084,722. Seaming non-metallic sheet material. O. B. RASMUSSEN. May 25, 1965 [March 31, 1964], No. 13300/64. Heading B5K. Thermoplastic organic film material is welded by applying, as a .welding aid to selected areas of at least one of the films to be welded, a thin layer of a low-molecular weight substance which is capable of dissolving the film material at the welding temperature and which is liquid at a temperature below that necessary to effect a substantial dissolution of the material, the low molecular weight substance being applied in liquid form and rapidly cooled to a congealed state, subsequently arranging the layers of film material in the desired position for welding and heating the arranged-layers sufficiently to make the welding aid at least swell the film material at the places to be welded but insufficiently to make the surfaces stick together without the welding aid. Preferably, the welding aid is applied to the film or films by printing, e.g. by an engraved roller, and is applied in a layer the thickness of which is 1-25% of the thickness of the films to be welded, the higher percentages being used for thinner films. Fine particles of the same polymer as the film material or a closely related polymer of preferably the same or similar molecular weight may be mixed with the welding aid. Specified films are high density polyethylene and isotactic polypropylene which are welded at a temperature in the range 95-120‹ C. Oriented film material may be used and the films to be welded may each be a laminate in which the directions of orientation of the single layers cross one another. The welding aid is preferably an aromatic hydrocarbon or a chlorinated hydrocarbon, e.g. one melting within the range 40-100‹ C., such as naphthalene or paradichlorobenzene. Polyethylene terephthalate may be welded by means of nitrobenzene in a cooled room. The welding aid may be applied to both sides of a narrow band of polymeric material which is interposed between the films to be welded together. The invention is applicable to welding block bottom bags. The films may be continuous or partly fiberized, e.g. an oriented polyolefine which has been mechanically treated to produce a multitude of splits or cracks close to one another.

Filed: 1939-05-04
Abstract: 528,757. Grid resistances. HUHNE, H. P. May 4, 1939, No. 13328. [Class 37] The loops of each element of a corrugated tape resistance are adjustably mounted between counterpart insulated clamping members which also serve as separators, the clamping members being perforated, shaped, and dimensioned so as to project from one or each side of the rod upon which they are adjustably assembled, together with insulators, the rod being furnished with clamping means so that the loops may be longitudinally adjusted. On rods or tubes 1 are slidably mounted a plurality of perforated intermediate clamping members 2 and interposed perforated mica, porcelain, or other insulators 3 between perforated slidable end clamps 4. so that the loops or bends a, a<1> of two strip resistances can be spaced apart and secured between corresponding insulators 3 and clamps 2, 4 by means of nuts 5. Each of the loops a, a<1> is stiffened by corrugations the number and arrangement of which varies with the width of the strip. Plain portions are left between the corrugated portions to permit the strip to be bent into loops. The corrugations are V-shaped to correspond with counterpart V-shaped projections and recesses 7, 8 on the clamping elements 2, 4, while the interposed insulators 3 are correspondingly shaped. In the case of wide resistance strips of a V-shaped corrugation may be formed near one edge of each of the loops a, a<1 >in addition to smaller longitudinal and transverse corrugations, so that such elements are secured at one edge in the insulated clamps. The intermediate clamping members 2 may be made from sheet metal such as aluminium or aluminium alloy and the corrugated ends thickened with layers of sheet metal or they may be cast in aluminium &c. with the corrugated ends thickened. Tappings may be taken by inserting contact plates of copper &c. between the resistance loop to be tapped and the insulators on each side of it, the contact plates being formed with corrugations corresponding to those on the resistance strip. The rods 1 are mounted in an angle-iron frame, which may be enclosed with panels and doors or removable covers.

Title: Improvements in or relating to a turbine or compressor inlet nozzle assembly
IPC: F01D9/04
Filed: 1958-04-28
Abstract: 878,988. Axial flow and centrifugal compressors; turbines. MASCHINENFABRIK AUGSBURG - NURNBERG A.G. April 28, 1958 [Oct. 31, 1957], No. 13432/58. Classes 110 (1) and 110 (3). In a turbine or compressor inlet nozzle assembly, the entire ring of guide vanes is subdivided into a number of sectors each comprising a plurality of vanes, each sector being pivotally mounted about an associated axis perpendicular to the direction of flow. As shown for an axial flow turbine (Fig. 3), the assembly is divided into four sectors 23a, 23b, &c., each pivotally mounted by a pin 25 in a housing part 21<SP>1</SP> movable radially in the turbine housing 21 to allow for thermal expansion. Each sector comprises a carrier part 30 rotatably received in a chamber 31 in the corresponding housing part 211 and biased radially inwards by a spring 28 to bear on the spherical peripheral face of an annular projection 33 on the housing. The clearances between the parts 21<SP>1</SP> are sealed by labyrinth packings. Each sector comprises six vanes (Fig. 6) spaced a constant distant t apart, the narrowest cross-sectional width of the passage between two adjacent vanes being # and the narrowest cross-sectional width of the passage between the end vanes of two adjacent sectors being 2# before the sectors have been pivoted. The normal vane passage area of 28 #h (where h is the height of each vane) may be decreased to 20 8h by pivoting the sectors in one direction so as to close the passages between the sectors, or increased to 36 8h by pivoting the sectors in the opposite direction to open these passages to 4#, thus providing a variation of up to 56% of the normal vane passage area. In an alternative embodiment (Figs. 1 and 2, not shown), the assembly comprises two semicircular sectors having sliding abutting diametral surfaces at least one of which may be provided with labyrinth packings. The peripheral faces of the two sectors and the counter face of the housing are spherical, a packing effect being produced in the radial clearance by the formation of peripheral slots in the outer ring of the assembly. Fig. 7 (not shown), illustrates the application of the invention to radial flow turbines.

Title: Improvements in and relating to the feed control of fuel for furnaces
IPC: F23K3/14
Filed: 1942-09-28
Abstract: 565,624. Regulating fuel supply. LINDARS,H. Sept. 28, 1942, No. 13613. [Class 51 (i)] The fuel feeding means of a furnace is driven intermittently by a motor which is started and stopped at intervals and the period during which fuel is fed to the furnace 'is regulated in accordance with the pressure difference on opposite sides of a constriction in the air supply conduit by means which causes the fuel to be fed in relation to the air supply according to square root and sine laws. As shown in Fig. 1, fuel is fed to the furnace by a screw conveyer 2 driven by an electric motor 41 and air is supplied by a conduit 5 provided with an orifice plate 8. The air pressure on opposite sides of the plate 8 is communicated through pipes 10 to chambers 15, 16 on opposite sides of a body of liquid 14 contained in an oscillatorily-mounted balanced ring 11 having a gap 13 or partition and provided with a. counterweight 17 so that the differential pressure on the surface of the liquid causes. the ring to rotate. The ring carries a cam 23, the profile of which is designed by taking into account a square root law owing to the volume of air supplied being measured by the , differential pressure and a sine law owing to the angular movement of the cam. A motor 31 drives shaft 33 which is provided at one end with a wiper 39 adapted at each revolution to close electric contacts 40 and start the fuel feeding motor 41. At the same time an electromagnet 36 in the motor circuit is energized and operates an armature 37 which moves a rotatable disc 28 against the action of a spring 35 into contact with a friction wheel 34 continuously driven by the motor 31. Rotation of the disc 28 causes the bar 26 to be moved by rack and pinion gearing against the action of a spring 27 towards the cam 23. The bar 26 carried a switch 24 in the circuit of the motor 41 and electromagnet 36 operated by spindle 25 which engages with the surface of the cam and opens the circuit of the motor 41 at a time determined by the position of the cam. In a modification shown in Fig. 3, the cam 23 is mounted on the ring 11 and the disc 28 co-operates with a bar 80 which is pressed against the disc by the electromagnet 36 and is moved towards the cam, the end of the bar being provided with a spindle and switch 24, 25 similar to that shown in Figs 1 and 2.
