Title: Improvements in combined hot water and steam boilers
IPC: F24D1/00
Filed: 1962-12-11
Abstract: 951,747. Steam boilers combined with hotwater boilers. GOTAVERKEN A.B. Dec. 11, 1962 [Dec. 13, 1961], No. 46800/62. Heading F4A. In a combined steam and hot-water boiler comprising pressurized water heating and steam generating circuits with respective tubulous heating surfaces 3, 4 disposed on a common furnace 1, the steam generating circuit includes a drum 15 from the water space of which an open connection 21 leads to the water heating circuit so that the drum serves as an expansion tank and pressure regulating device for that circuit in which the water temperature exceeds 100 C. In the hot water circuit a pump 9 forces water through the tubes 3 and a coil in a heat exchanger 6 wherein it heats water for a central heating system connected at 7 and 8. The pump speed is controlled to maintain a constant temperature in the flow pipe 7 whilst the fuel supply to the common furnace burner 2 is controlled to maintain constant the water temperature at the outlet from the tubes 3. In the steam generating circuit a pump draws water from the drum 15 and returns it thereto through the heating surface 4. Feed water is supplied to the drum through a line 16 having a regulator valve 20 set according to drum level by a device 19. A pressure sensitive member 23 controls two valves 24, 27, opening the former to admit a spray of water from the hot water circuit into the drum if the pressure therein rises above a preset value in the event of decreasing steam demand and closing the valve 27 if the demand exceeds the generation rate to maintain a constant pressure in the drum and hence in the hot water circuit through the open connection 21.

Abstract: 1,163,058. Bending non-metallic material. TETRA PAK A.B. 16 Oct., 1967 [24 Oct., 1966], No. 46996/67. Heading B6J. [Also in Division B8] A web of material 1, e.g. of stiff paper coated with polyethylene, which is to be fed into a packaging machine, and which has transverse fold lines 2 formed thereon intended to define the corners of the package, is driven along a non-linear path causing it to buckle along the fold lines 2 to facilitate folding in the machine. As shown, the material 1 is fed by two pairs of feed rollers 3, 5 and 4, 6, and between the feed rollers it passes over a series of guide rollers 7 . . . 10 in a path causing the buckling or prefolding along the lines 2. The packages may be produced by first forming the web of material into a tube and then sealing it transversely to close the end of each package. Filling of the package is effected whilst the package is within a former, the inner surfaces of which move relatively to one another to compress the package to shape.

Title: Lockbolt placing apparatus
Inventor: SANDERS JOHN STEWART
IPC: B21J15/00
Filed: 1968-10-04
Abstract: 1286466 Riveting AVDEL Ltd 3 Oct 1969 [4 Oct 1968] 47177/68 Heading B3U A lockbolt placing apparatus comprises an hydraulic master piston 11 reciprocable in a master cylinder 12 one side of which is connected to an hydraulic reservoir 25 and both sides of which are connected by hydraulic connections 19, 21 to the opposite sides of a slave cylinder 15 which is connectable to an anvil for swaging the lockbolt collar and in which reciprocates a slave piston 14 connectable to a lockbolt stem gripping device. In operation, the trigger (53) (Fig. 2, not shown) of the tool is depressed to actuate a valve member (48) (Fig. 5, not shown) of a pneumatic valve (46) which allows compressed air to raise a piston 44 and the connected master piston 11. Hydraulic fluid is forced into the slave cylinder 15 via the connection 19 to drive the piston 14 rearwards causing the stem gripping jaws (66) (Fig. 8, not shown) to be retracted and the anvil (61) to be forced over the lockbolt collar. A deficiency of hydraulic fluid is produced in the connection 21 due to the different effective areas of the pistons 11, 14, which deficiency is rectified by fluid being drawn from the reservoir 25 through a non-return valve 27. The fluid is contained in a compressed foam rubber tube 36 which expands to fill up the space in the reservoir 25 occupied by the withdrawal of fluid. When the collar has been swaged into the locking grooves in the stem and the stem has broken, the trigger (53) is released to cause the master piston 11 to move downwards and the slave piston 14 forwards. The pressure in the connection 21 is thereby increased, the high pressure behind the piston 14 allowing the ejector sleeve (73) to pull the anvil (61) off the swaged collar. The excess fluid in the connection 21 is discharged into the reservoir 25 through a pressurized inlet valve 31 which opens at a pressure differential of 1500 p.s.i., the rubber 36 being compressed to accommodate the fluid. The reservoir 25 is designed to absorb the extra excess fluid produced if the slave piston 14 is prevented from moving forwardly due to jamming of the jaws (66).

Title: Power lift for a tractor
IPC: A01B63/112
Filed: 1972-10-13
Abstract: 1400031 Tractor power lift mechanism MASSEY-FERGUSON SERVICES NV 13 Oct 1972 [15 Oct 1971] 47259/72 Heading A1P A tractor power lift mechanism comprises a draft control operated via a link 65 with follow up provided by a member 37 and a link 69 and also a depth limiting linkage operated by a link 101 and is characterised in that the mechanism is in two portions, one carried by the main housing 15 and the other by the detachable part 17. The detachable part supports the valve V and bell cranks 43, 49, 107 and has access holes for adjustment of screws 105 and 54. The remainder of the mechanism is mounted in the main housing 15. The detachable part 17 can be removed by means of screws 20, for the purpose of, for instance, servicing. The mechanism is so arranged that separation and reassembly of the detachable part requires neither special disconnection beforehand nor readjustment afterwards of the linkage. Operation. In order to lower the draft linkage, link 65 is moved forwards to cause a shaft 61 and also a member 67 to rotate anticlockwise about the axis 59. This will cause rearward movement of a shaft 60, a sleeve 64 and a pin 58 and simultaneously urge a control rod 53 rearward through the spring 55. This motion is transmitted through a bell crank 49, a link 47 and a bell crank 43 to the valve operating rod 41, to urge the valve V against its spring into a position to allow the implement to lower. As the implement enters the ground, a draft sensing device causes the input member 37 to be moved downwards. This downward movement acts through the link 73 and lever 69 to rotate the shaft 64 counterclockwise, acting to relieve the force through a spring 55 on the member 53 to allow the valve V to close. When the draft force has increased to the figure preset by the link 65, then a member 37 will have moved downwards sufficiently to close off the valve V. A link 101 is set to a position representing the maximum depth to which the implement is required to go. This movement of link 101 acts through the links 99, 95, pin 93 and link 89 to locate the lower pin 90 of the floating lever 83. As the implement is lowered, the rock shaft 16 rotates clockwise causing a lever 85 to move forward. Through the intermediate pin 92, the extension 79 on the control rod 53 is moved rearward and when the maximum depth selected is reached the valve V will be closed off.  In order to raise the implement out of the ground, the lever 65 is moved rearward to cause the shaft 61 to rotate clockwise which causes forward movement of the forked member 57, thereby moving the control rod 53 forward and through the bell crank 49, lever 47 and bell crank 43, permit the valve V to allow oil into the cylinder raising the implement. As the implement is raised, the rock shaft 16 rotates counter clockwise and when a maximum transport height is reached, the pin 109 engages the arm of the bell crank 107. This action urges the bell crank 43 to shut off the valve and hence to stop the raising of the implement.
