Title: Machine for rolling and wrapping newspapers, periodicals and the like
IPC: B65B25/14
Filed: 1954-11-26
Abstract: 761,741. Rolling and wrapping newspapers and periodicals. KERR, G. A. Nov. 26, 1954 [Dec. 16, 1953], No. 34291/54. Class 94(1). A machine for rolling and wrapping newspapers or periodicals comprises two opposed forked members rotatable about a common axis and movable axially towards each other so as to embrace the side edges of the newspaper and roll it within a cylindrical space defined by two sets of resiliently-mounted rollers, the members being withdrawn when the rolling is complete and the sets of rollers moved apart to discharge the rolled newspapers. Each forked member 53. 54, Fig. 6, is secured to a rod 55 which is slidable between rollers journalled in brackets secured to a sleeve journalled in a fixed housing 56, the sleeve being rotated by a sprocket 59 and chain (not shown). The ends of the rods 55 are coupled to levers 69, 70, Fig. 1, operated through push-rods 67, 68 by a cam 13 on a shaft driven by a sprocket 12, the levers also actuating links 71, 72 coupled to mechanism, see Figs. 7 and 8 (not shown), which varies the slack in the chains driving the sprockets 59 so that the rotation of the forked members' is temporarily arrested as they move inwardly to enable them to embrace the newspaper. The sets of rollers 19, Fig. 2, are mounted on brackets 17 and 18 which are pivoted to supporting links 21, 20 and arranged to be swung to an open position against the action of a spring by links and bellcrank levers 25, 27 and 24, 26 operated through rods 28, 29 by a weighted lever 30 carrying a roller 31 engaging a cam 14 on the shaft of the cam 13. An extension 35 of the lever 27 is coupled to a rod 36 which controls the engagement of newspaper-feeding and holding rollers 40, 38 with driven rollers 42, 43. As a newspaper is fed over a table 50 it engages an abutment 49 on a lever 48 and unlocks a spring-loaded trip lever 47 which moves a stop 44 to an inoperative position so that the roller 40 is moved downwardly when the control rod 36 is moved upwardly by.the lever 27 as the sets of rollers 19 are.moved apart by operation of the lever 30 to discharge a previously-wrapped newspaper. The rollers 40, 42 feed the newspaper forwardly until its front end lies between the rollers 38, 43, whereafter the cam 14 actuates the lever 30 to close the sets of rollers 19 and operate the control rod 36 to cause the rollers 38, 43 to engage and feed the newspaper down a shoot 51 into the space between the rollers 19. The forked members are then moved inwardly to roll the newspaper. After about one turn has been completed, a gummed wrapper is fed from a roll 52 by mechanism driven through a onerevolution clutch 16 controlled by the lever 47 and is rolled around the newspaper.

Title: Improvements in or relating to textile calenders or the like machines
Inventor: HARZENDORF GERHARD
IPC: D06C15/02
Filed: 1960-10-06
Abstract: 887,968. Calendering fabrics. ERSTE MASCHINENFABRIK KARL-MARX. STADT VEB. Oct. 6, 1960, No. 34345/60. Class 42 (1). A textile calender or like machine having two outer rolls 1, 2 and two inner rolls 3, 4 disposed therebetween, the inner rolls being adjustable in the peripheral direction of the outer rolls and arranged to act as working rolls defining a working gap for the material 6 to be treated, is characterized in that the inner rolls are arranged to be driven by friction by the outer rolls, the latter being driven in opposite directions, and in that the gap between the outer rolls is smaller than the sum of the diameters of the inner rolls so that the frictional drive from the outer rolls to the inner rolls tends to move the inner rolls closer to the gap between the outer rolls. As illustrated the rolls 3, 4 are journalled in slots 7, 8 in arms 9, 10 mounted on journals 11, 12 of rolls 1, 2. The arms 9, 10 are connected by links 13, 14 on both sides of the frame 17 to a common yoke 15 connected to rod 16 resiliently loaded by spring 19 so that the rolls 3, 4 are held resiliently in a position close to the gap of outer rolls 1, 2. Consequently the rolls 3, 4 can further approach the narrowest gap between rolls 1, 2 if the web 6 has a thin part and conversely can yield in the direction of the running web 6 if a relatively thick part should enter the gap 5. Either or both of the rolls 1, 2 may be resiliently mounted and a third outer roll may be provided above roll 1 or below roll 2 with a second pair of inner rolls 3, 4 to provide a second passage for the material to be treated.

Abstract: 1418348 Sewage treatment MASCHINENFABRIK HELLMUT GEIGER GmbH & CO KG 19 July 1973 [20 July 1972] 34505/73 Heading C1C A sewage percolating tank of the kind which is charged with the sewage and supplied with air for promoting organic growth in the charge, wherein said tank contains plate means for supporting a growth coating and movable stripping means capable of mechanically detaching the growth coating. In operation, the tank is charged with the sewage and supplied with air and the organic growth mass is mechanically detached from the surfaces before said mass reaches the stage where it automatically detaches itself due to its biological and/or physical action. In the embodiment of Fig. 1 a charging device 2 is arranged in a casing 1 above rectangular parallel plates 3. Sewage enters at 2 and flows through the plates, over the inclined base 4 and out of the drain 5. The air enters at 6 and leaves at 7. The plates 3 are separated by spacing members 8 and are mounted in a hinge joint 9. A stripping device 11 is rotatably mounted at 12. In normal operation the plates 3 and device 11 occupy the positions shown in full lines. In order to detach the growth coating, the device 11 may be rotated to position 13 thus stripping half of the plate 3 and the plate may be rotated to position 10, stripping the other half of the plate. When both plate and device 11 are in the positions shown in dotted lines they form an inclined surface down which sludge settles to be removed through access plate 14. The sludge has low water content and in most cases sedimentation is unnecessary. In another embodiment, Fig. 2 (not shown) the plates themselves form the stripping device, two sets of interlocking plates being provided, each in a comb formation. Preferably no liquid is delivered to the tank during stripping, which may be automatically controlled.

Abstract: 1,159,688. Pipe couplings. INTERNATIONAL HARVESTER CO. 3 Aug., 1966 [16 Aug., 1965], No. 34730/66. Heading F2G. An hydraulic fluid coupling comprises a coupling member 12 having a valve body 20 with a bore 22 connectible to a first conduit 28 and formed with a valve seat 30 on to which is biased by a spring 48 a valve 38 slidable in the bore and provided with a snout 42, and a coupling member 14 having a piston 68 the bore 100 of which is connectible to a second conduit and a cylinder 60 slidable on the piston for movement between first and second limit positions, the cylinder and piston being shaped to provide a fluid-receiving zone 80 therebetween which zone, when the cylinder is in the first limit position thereof has a greater volume than when the cylinder is in the second limit position, the cylinder is biased by a spring 78 towards the first limit position and there are means for releasably locking together the coupling members and which may comprise a sleeve 90 biased by a spring 92 to move balls 86 radially inwardly into a groove 56 in the member 12 when the latter has been fully inserted into the member 14. A valve seat 110 formed in the bore 100 of the piston divides the bore into fluid chambers 114, 116, the chamber 114 being in communication with the zone 80. A valve 128 slidably positioned within the piston and having a body 134 and a snout 130 is biased by a spring 154 into engagement with the seat 110 to prevent fluid flow therethrough, movement of the valve away from the seat being limited by means such as the closed end of a cylinder 172 in which the valve may slide. Coupling of the members is effected by inserting the member 12 into the member 14 with the snouts of the valves in engagement to move the valve 128 off the seat 110, further movement of the member 12 causing the cylinder to slide over the piston towards the second limit position thereof a distance sufficient to allow engagement of the locking means 84 in which position fluid under pressure supplied to the bore of the piston will cause movement of the piston within the cylinder so that the latter returns to the first limit position and the engaging valve snouts force the valve 38 off the seat 30 whereby the coupling members and conduits are placed in fluid communication.

Title: Improvements relating to liquid pumping systems
Inventor: MARSLAND JACK RONALD
IPC: B63B27/24
Filed: 1964-08-25
Abstract: 1,047,124. Centrifugal pumps. WORTHINGTON-SIMPSON Ltd. May 6, 1965 [Aug. 25, 1964], No. 34807/64. Heading F1C. A liquid pumping system comprises a centrifugal pump 1 driven by a turbine or electric motor and connected by a feed pipe 4 to the cargo or ballast tanks of a tanker ship. During discharge of the cargo, the liquid level in a separating chamber 3 is depressed by vapour accumulating therein, and the vapour pressure is communicated to a liquid level controller 7 which responds and sends out a pneumatic signal to various controls. Initially, the increasing signal pressure opens a diaphragm controlled valve 11 to communicate the chamber 3 with atmosphere via an intercepting chamber 13 having a moisture separator. Further increase in signal pressure closes switches 8 to a vacuum pump 6 which discharges the vapour together with pump sealing water to a separating tank 20 vented at 21 and containing a cooling coil 22 cooled by sea water. During final draining of the cargo tank the higher signal pressure, communicated through a selector relay 25, causes progressive closing of a valve 14 in the discharge line of the pump 1 and reduction in the pump speed. The valve 14 may be operated manually and locked in open, shut and draining positions. In the event of excessive temperature of the discharge from pump 1, a thermostat 23 stops the pump. Overloading of the pump 1, as by pumping high viscosity liquids, is avoided by applying an over-riding pneumatic signal through the selector relay 25 to the valve 14 to cause it to throttle the flow. This signal is applied either by a hand-set air regulator 26 connected to an air supply line 27, or by an electro-pneumatic device 28 which senses the driving motor current by a current transformer 29 and produces a suitable pneumatic signal through a controller 30. The pump may be shut down in an emergency by venting the pneumatic signal lines and isolating the air supply. A valve 18 prevents undue gasification due to excessive vacuum.

Filed: 1955-12-07
Abstract: 817,392. Stuffing-box substitutes. GITS BROS. MFG. CO. Dec. 7, 1955 [Nov. 1, 1955], No. 35124/55. Class 122 (5). In a seal for use between relatively rotatable elements, such as a rotary shaft and a wall through which the shaft extends, comprising a support 11, Fig. 1, carried by one of the elements and carrying an annular member 15 axially movable relative to the support and having a sealing face 17 to engage a sealing face on the other element, the member 15 is sealed to the support by a resilient packing ring 21 which is housed in a recess in the member, axially compressed by a spring 25 and prevented from being blown out of position by fluid pressure by an inturned flange 27 at the open end of the recess. The support 11 comprises inner and outer cylindrical walls 12 and 13 connected by a radial wall 14 and ridges 18 on the outer wall 13 engage in grooves 19 in the member 15. The ring 21 of natural or synthetic rubber is compressed between a metal washer 24 and a washer 26 of polytetrafluoroethylene, silicone rubber or other heat-resistant elastomer, by the spring 25 so that it is urged into sealing contact with the wall 12 and the recess wall 22. The spring 25 also acts to urge the sealing face 17 into contact with its cooperating sealing face and the areas 28, 29, 30, 31 and 32 are arranged so that increase in pressure of the sealed fluid results in increase in contact pressure between the sealing faces. In a modification, Fig. 2, a wedge-section washer 45, which may be of polytetrafluorethylene or silicone rubber, is pressed into sealing contact with the recess in the member 39 and the support 35 by springs 49, 51 acting on a frustoconical section metal or other rigid washer 48. In a further modification, Fig. 3 (not shown), a resilient washer has a frusto-oonical surface co-operating with a similar surface of a rigid washer, both washers being axially compressed in the recess in the member 39 by a spring.

Title: Improvements in or relating to gyratory crushers
Inventor: KUENEMAN DON
IPC: B02C2/04
Filed: 1968-07-23
Abstract: 1,236,944. Gyratory crushers. D. KUENEMAN and C. P. KENVILLE. 23 July, 1968 [27 July, 1967], No. 35168/68. Heading B2A. A gyratory crusher 10, Fig. 1 has provision for automatic adjustment of the crushing bowl and gap and overload protection. The crusher has a main frame 11 supporting an adjusting ring 12 via a spring system 15, 16. A threaded inner surface 18 of the ring 12 mates with a threaded bowl 20. Thus by rotation the bowl is movable axially relative to the ring. The control system for the threaded connection between bowl and crusher comprises a thread clearance removal system 30, a locking system 50 and a bowlrotating system 70, which are hydraulically actuated from a common control system. Thread clearance removal system: To remove lost motion in the connection between bowl and ring a floating ring 31 is fitted over the upper portion 20A of the bowl 20 with a key 32 to prevent rotation and springs 33 to support the ring. The outer threaded periphery of the floating ring can be screwed into an upper wall 12A of the adjusting ring, and thus the floating ring maintained in a constant axial position relative to the bowl. Hydraulic piston lifting mechanisms 34, 36 are mounted around the top of the bowl and operate against the floating ring. The bowl is normally lifted upwards by springs 39. Hydraulic operation of mechanisms 34 moves the pistons 36 and consequently compresses the springs 39 and releases the bowl. In an alternative form the upper wall 12A is fabricated separately, Fig. 2 (not shown). Locking mechanism: Posts 51, Fig. 4, are mounted on the ring 12 and in pairs support leaf springs 52. Each spring set carries a locking lug 54 which engages between ribs 27 on a vertical side 26A of the crusher cap 26. To release the lock a ram cylinder 55 is actuated. Bowl rotating system: After the lifting and locking mechanisms have been released an hydraulic interlock including a pressure-sensitive switch permits actuation of a rotary actuator 71 mounted on the ring 12 and having a double-ended pawl 72 connected to an oscillating arm 73. Reversal of the rotational direction of the bowl is effected by an hydraulic cylinder 78, which swings the actuator. Limiters 80 on the adjustment ring engage a limit arm 81 of the actuator and reverse the fluid flow when contacted. The upper wall 12A has bearings 82 to reduce friction, so that the bowl may be rotated with a single actuator.
