Title: Improvements in and relating to Distributing Rollers in Inking and Damping Units of Printing Machines.
IPC: B41F31/15
Filed: 1968-09-20
Abstract: 1,196,847. Printing machines. HEIDELBERGER DRUCKMASCHINEN A.G. 20 Sept., 1968 [24 Nov., 1967], No. 44837/68. Heading B6C. In a printing machine, the distributing roller 1 of the inking or damping apparatus is removable for the cleaning of the damping rollers or replacement of the inking rollers, and for this purpose has coaxially housed within it telescopic components 6, 7 in screw-threaded engagement with one another, each component being coupled to one of the roller journals 2, 3 for axial movement therewith, the components 6, 7 being rotatable relative to one another by means outside the roller 1 so that the roller is either clamped to the journals or the journals are moved to positions permitting removal of the roller 1. The component 7 is keyed to the roller 1 and has a groove 12 engaged by a forked part 13 on the journal 2. A flange 14 on the journal 2 engages a recess 15 in the end of the roller 1 and a hole 17 in the flange 14 engages a pin 16 on the roller when the journal and roller are clamped together. The component 6 is rotatable in a bore 22 of the roller 1 and also has a groove engaging a forked part 19 on the journal 3, the latter carrying a flange 25 for engaging a recess 26 in the end of the roller 1 when the parts are clamped together. A key 20 extends into an axial groove 21 in the bore 22 to engage the surface of component 6 to hold the latter and the roller 1 in proper radial alignment with the journals. A turn key 28 can be inserted through a bore 27 in the journal 3 so that its flat end 29 engages a diametral recess and the end 18 of component 6 to rotate the latter and move the journals together with flanges 14, 25 apart or towards one another. In the apart position, the flanges 14, 25 are moved away from the recesses 15, 26 so that the roller 1 can be removed by lifting the components out of the forked parts 13, 19. Within the component 6 is a blind hole or bore 31 containing a plunger 34 urged towards the end 18 by a spring 33. In the clamping position the plunger 34 is moved inwardly and causes balls 35 mounted in holes in the component 6 to be moved radially outward to engage a shoulder 22<SP>1</SP> formed by an enlargement 122 of the bore 8 in the roller 1. This prevents any outward movement of the part 6 notwithstanding any tendency of the latter to rotate. When the turn key 28 is inserted, its end 29 moves the plunger 34 inwardly so that the balls 35 can drop into an annular groove 36 in the plunger to release the latter and the component 6.

Title: A Control Circuit for Static Converters

IPC: H02M7/757
Filed: 1966-10-20
Abstract: 1,176,484. Converting; control of D.C. motors. ENGLISH ELECTRIC CO. Ltd. 18 Oct., 1967 [20 Oct., 1966], No. 47066/66. Headings H2F and H2J. In a control device for a static converter, firing pulses are withdrawn from one or more controlled rectifiers in response to inverse voltage occurring during the interval when said rectifier(s) is conditioned to conduct. The system is applicable to control of a system (Fig. 1, not shown) in which the outputs of a pair of polyphase bridges are connected in parallel opposition to a D.C. motor so as to provide forward and reverse power to the motor. In order to increase motor speed, the firing angles of the thyristors from the appropriate bridge are reduced in the normal manner but to decrease motor speed, the conducting bridge is first blocked and the other bridge conditioned to invert so as to absorb energy from the slowing motor. When the desired speed has been reached the inverting bridge is blocked and the other bridge rectifies again at the appropriate firing angle. In order to reverse the motor the initial procedure is adopted again but the inverting bridge is maintained in that state until the motor stops and is then conditioned to rectify. In such a system, the withdrawal of firing pulses from the rectifiers of one of the bridges must only occur when those rectifiers are non-conductive. Reduction in motor speed or in supply voltage during this time causes an inverse voltage to appear across one or more rectifiers. This inverse voltage is detected by diodes D2, D3 and causes a short circuit to appear across the primary of transformer T1. The rectifier firing pulses are supplied via capacitor C3 to a NOR gate N1 whilst firing pulses delayed by 60 degrees are supplied to a NOR gate N2, gates N1, N2 being cross-coupled to form a bi-stable circuit. Auxiliary 15Á, 5 kc./s. pulses supplied to the base of transistor TR1 result in inverse pulses being passed via the short-circuited transformer T1 and Zener diode ZD1 to a further NOR gate N3. This gate thus only provides an output of such pulses if the controlled rectifier 1 has inverse voltage during a period between the firing time and a time 60 degrees later. This output is used to withdraw the firing pulses from one or more of the controlled rectifiers. The circuit shown in Fig. 5, may be connected to one or more of a number of parallel thyristors isolated by respective current-limiting reactors.
