Title: Improvements in or relating to stereotype plate clamping means of rotary printing presses
IPC: B41F27/10
Filed: 1944-03-13
Abstract: 571,934. Printing-surfaces. HADDAN, R. (Duplex Printing Press Co.). March 13, 1944, No. 4644. [Class 100 (ii)] A clamping means which is especially applicable for clamping tubular printing- plates B to cylinders A is constructed with a number of clips 16 which are simultaneously operable to engage the edge B<1> of the printing-plate, and as the clips are moved axially of the cylinder by actuators 11 from a position in which the bevelled edges 16c of the clips are at a level below that of the inside of the tube B (permitting the tube B to slide thereover), the clips are moved radially outwards so as to cause engagement of the edge B<1> by the clips. Similarly, as the clips are withdrawn from the edge B<1>, they are moved radially inwards. The actuators 11 are moved axially in T-shaped slots A<7> in the cylinder and have yieldable connections with a ring 4 which is moved over a reduced part A<1> of the cylinder by means of radial arms 3 attached to a screw 2 of a jack arranged in the bearing end of the cylinder, the arms 3 being guided by slots A<6> in the reduced part A<1>, and so acting to prevent rotation of the screw. The screw 2 which is coaxial with the cylinder is operated by means of a threaded member 1 passing through ball bearings C and fitted with an extension 1e passing through ball bearings 6, the member 1 being prevented from axial movement and being fitted with a rectangular projection arranged in a guard 7 and adapted to receive a wrench for actuating the member 1 and screw 2. The clip 16, Fig. 7, is formed with an inclined T-shaped projection 16a which slides in a T -shaped slot 11c in the actuator 11. The front end of the clip 16 is fitted at each side with spring-pressed studs 16d which grip the sides of the slot A' to prevent forward movement of the clip 16 as the actuator 11 moves from left to right in Fig. 3. The first movement of the clip 16 is thus radially outwards. Finally, however, it advances so as to engage the edge B<1> as shown in Fig. 3. On reversal of the motion of the screw 2, the clip is moved radially inwards after releasing the edge B<1>. To permit of the use of plates of various lengths, the slots A<7> are made long, and they may be fitted with filler blocks 20, Fig. 10, which can be inserted in the slots A<7> with the straight sides parallel to the sides of the slots, then rotated 90 degrees to the position shown in Fig. 10, and then held by screws 21 formed with non-circular tool-engaging sockets in their upper ends adapted to be engaged by a tool inserted through the slots A<7>.

Title: Improvements in voltage regulator
IPC: G05F1/52
Filed: 1948-02-20
Abstract: 654,116. Automatic and current control systems. SORENSEN & CO., Inc. Feb. 20, 1948, No. 5108. Convention date, April 17, 1946. [Class 38 (iv)] An A.C. voltage or current regulator comprises an auto-transformer, the input to which is varied by a saturable reactor controlled by the amplified output of a bridge circuit, one arm of the bridge being a tungsten filament diode, the filament current being varied in accordance with the output voltage or current. In a voltage regulator, Fig. 3, the auto-transformer 46 is in series with a saturable reactor 37 across the input terminals 21, 22, the output being taken from terminals 31, 32. The D.C. winding of reactor 37 is controlled by an amplifier valve 35 supplied with D.C. by a rectifier 40 and winding on transformer 24 fed from the output terminals. A voltage is applied to the control grid of valve 35 whenever the bridge, consisting of resistors 10, 11, 12 and the diode 13, is unbalanced. A high D.C. voltage derived from transformer 24 and rectifier 33 is applied across the imput corners of the bridge, the balance of which is determined by the impedance of diode 13 in turn determined by the filament current provided by a transformer 51, the primary of which is connected in series with resistors 29 and 39 across the output terminals 31, 32. Resistor 39 is for datum setting. Resistor 29 applies a voltage component proportional to input voltage becuase it is in series with the supply to the primary of transformer 24 the load on which varies according to the D.C. excitation of reactor 37 and this varies with the input voltage to the regulator. A transformer 61 in series opposition to transformer 51 applies a component proportional to the output current through a shunt 57, to obtain level compounding. A condenser 49 across bridge resistor 11 prevents hunting. In a modification, Fig. 5 (not shown), the diode filament is supplied by three transformers in series, the third transformer supplying a voltage proportional to the input voltage. In another embodiment, Fig. 4 (not shown), output current is stabilized by supplying the diode filament from the secondary of a current transformer in the output line and also by an opposing voltage proportional to output voltage to stabilize the regulator. The transformer supplying the auxiliary D.C. circuits is supplied from the input terminals instead of the output.
