Title: Cylinder Drives for Multi-colour Sheet-fed Rotary Printing Machines
IPC: B41F13/012
Filed: 1967-04-24
Abstract: 1,160,011. Rotary printing presses; driving arrangements. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. 24 April, 1967 [7 May, 1966], No. 18841/67. Heading B6C. In order to eradicate the possibility of " hunting " of the wheels and cylinders in the common drive of a multi-colour sheet-fed rotary printing machine having a series of printing units and at least one transfer cylinder between the impression cylinders of adjacent units, auxiliary gear wheels are provided in the drive which are resiliently connected to other gear wheels such that each resilient connection exerts a force in a direction resulting in the teeth of each auxiliary wheel abutting against the non-driving flanks of the gear wheel with which said auxiliary wheel is in mesh. In the described embodiment the impression cylinders 3 of successive units are interconnected through gear wheels 4, 5, 6, 7 and 11 and auxiliary gear wheels 12, 13, 16, 14 and 15, Fig. 2. The wheels 12, 13, 14 and 15 are resiliently mounted through spring mechanism on the respective driving gear wheels 5 and 7 so that in operation of the machine any play which occurs between the meshing teeth of the cylinder driving wheels is immediately compensated for or suppressed.

Title: Turbojet engine having variable-angle fan blades
IPC: F02K3/04
Filed: 1973-04-18
Abstract: 1420679 Axial-flow fans; gas-turbine ducted-fan engines MOTOREN-UND TURBINEN-UNION MUNCHEN GmbH 18 April 1973 [19 April 1972] 18864/73 Headings F1C and F1J In a gas turbine ducted-fan engine, an annular piston arranged for energization by compressor air and connected to drive an actuating mechanism for changing the fan blade angle is arranged coaxially with the engine centreline and disposed, together with the actuating mechanism, substantially in an annular region located between the main duct of the engine and the fan duct. When the angle of the fan blades 2 is to be changed, compressed air is supplied via a control valve 34 to either of two pipes 35, 36. When the air is supplied to pipe 35, it passes, via a duct 40 in a stay vane 14, a chamber 42 and an annular chamber 47 to act on a portion 48' of an annular piston 48, whereby the annular piston is moved to the left and acts, via gearing 49, 50, 52, 53 to withdraw spring-loaded plungers 54 from engagement with slots 55 in racks 27. This unlocks the fan blades 2, each of which is adjustable by a corresponding one of the racks. The piston is now in a position in which the portion 48' is to the left of a duct 56, whereby compressed air can flow from the chamber 47 to the duct 56 and thence via a chamber 57, a passage 58, a chamber 59 and a pipe 60 to an annular chamber 25, where it acts on an annular piston 20 to move the racks 27 to the left and therefore change the blade angle, e.g., for cruising or for reverse thrust. The valve 34 is then actuated to relieve the pressure, allowing the piston 48 and the plungers 54 to be returned by springs to their original positions. The plungers 54 then engage slots 61 in the racks 27 to retain the blades 2 in their new positions. When the blades 2 are to be returned to their original positions, the control valve 34 supplies compressed air to the pipe 36 and hence, via a duct 39, a chamber 41 and an annular chamber 46 to act on a portion 48"of the piston 48, whereby the piston is again moved to the left to withdraw the plungers 54 from engagement with the racks 27 to unlock the blades 2. The portion 48" will now be to the left of a port 66, allowing the compressed air to pass from the chamber 46 via the port 66, a chamber 65, a passage 64, a chamber 63 and a pipe 62 to an annular chamber 21, where it acts on the annular piston 20 to move the racks 27 to the right. The position of the annular piston 20 may be sensed by means of iron cores 68 carried by the piston and moving relatively to the windings 69, 70 of a differential transformer to provide a control voltage to actuate the control valve 34 when the blades 2 have reached the required position.

Abstract: 664,810. Fluid-pressure servomotor control systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. July 19, 1949 [Aug. 11, 1948], No. 18976/49. Class 135 A steam turbine having a valve controlled by a fluidpressure servomotor to regulate the flow of steam to the turbine in accordance with its speed includes a speed governor 9, Fig. 2, an emergency overspeed governor 10 and a steam chest 12 for the admission valve 28 and the servomotor. The servomotor comprises differential pistons 42, 44 slidable in a cylinder 26 surrounded by a sleeve 25 leaving a space 53 therebetween through which passes inlet steam to the face 51 of the piston 44. The piston 42 is integral with the valve 28 and a stem 46 which abuts the piston 44, whilst the piston 44 has an axial bore 58 controlled by a needle valve 60 operatively connected to the governor 9 by a spring 72 and a lever 69 to permit the escape of steam from the face 51 through the bore 58 and a passage 58b to atmosphere. On, e.g. a decrease in turbine speed due to increased load, the lever 69 turns anti-clockwise so that the valve 60 opens and releases the pressure on the piston 44 to exhaust and the now unbalanced pressure on the left face of the piston 42 moves the piston assembly to the right to follow-up the movement of the valve 60 and open the valve 28 until the forces on the pistons 42, 44 are again equal. In the event of overspeeding of the turbine, the governor 10 acts through a lever and spring '(not shown) to disengage a cam piece 79 from a spring- loaded cup member 74 which, when released, engages a collar 84 to move the valve 60 to close the bore 58 and hence move the piston assembly to the left to close the valve 28. To reset the overspeed governor after use a lever 85 is provided.

Abstract: 1,046,996. Dividing by fusion. RAYMOND INTERNATIONAL Inc. May 7, 1965 [June 9, 1964], No. 19298/65. Heading B3V. Helically welded tubing 15 is cut into predetermined lengths by a plasma torch 14 supported on a carriage 20 which advances with the rotating tube as it is fed from a welding station. A disc 33 carried by a pivoted arm 32 (Fig. 5, not shown) engages the leading edge of the tube and is mounted on a carriage 21 interconnected with carriage 20 so that as the tube advances it moves the carriages with it. The carriages are slidable on rods 17 and 18 (Fig. 3, not shown) and interconnected by tubes 30, the spacing of the carriages being adjustable to alter the length of tube to be severed. The disc 33 is mounted on a ball joint 34 to allow the disc to tilt slightly if irregularities exist on the previously severed tube end, this movement of the disc allowing more accurate control of the length of the tube to be made. The carriage 20 is returned to its initial position after cutting of the tube by a spring-loaded cable 26, a pneumatic tyre 29 bringing the carriage softly to rest. Operation of the torch 24, and pivoted lever 32 are controlled by switches 40, 43, 44 and 45 mounted adjustably on a fixed beam 17a and co-operating with the carriage 20. The tube 15 is supported by rollers 59 on support beams 57 and 58 and is urged downwardly by adjustable rollers 60 and 61. After being cut a tube length is supported initially by arms 47-50 and is then lowered on to a conveyer 52 for removal. The various supports mentioned and also the main supporting structures 16 and 19, are adjustable to accommodate tubes of different diameters. During cutting of the tube water is sprayed from the carriage into the cutting area to control fumes and oxide particles which are produced. The water is subsequently removed from a severed tube by tilting it as it is lowered on to the conveyer 52.
