Title: Addressing machines
IPC: B41L47/18
Filed: 1961-12-11
Abstract: 964,601. Addressing-machines. FABBRICA ITALIANA MACCHINE AZIENDALI. Dec. 11, 1961 [Dec. 16, 1960], No. 44246/61. Headings B6C and B6D. Stopping, starting, tripping, &c.-A device for advancing the address plates in addressing machines comprises at least one flexible closedpath member with means for pushing the plates and driven with unidirectional intermittent motion, said motion is derived from a continuously rotating shaft, and means is provided for disconnecting the transmission for a predetermined fraction of each revolution of the shaft. The drive shaft 24 carries a gear 25 during a gear 26 keyed on a shaft 27 and integral with a disc 33 having peripheral notches 34, 35 spaced 180 degrees. The flexible member is a chain 2 driven by a sprocket 14 freely mounted on the shaft 27 and rigidly connected with a plate 28 to which there is pivoted at 29 a dog 30 having lugs 31, 32. During rotation of the gear 25 from zero position as shown to 120 degrees, the gear 26 is rotated through 180 degrees, rotating the sprocket 14, until the lug 31 abuts the end of an arm 40 and disengages the lug 32 from the notch 35. During rotation of the gear 25 from 120 degrees to 240 degrees the sprocket 26 is stationary, and at 240 degrees a stud 41 rotates an arm 43 to move the arm 40 clear of the lug 31, whereupon the lug 32 moves into the notch 34, which is now aligned with it. During rotation of the gear 25 from 240 degrees to 360 degrees and on to 120 degrees the sprocket is again rotated. During each period of motion of the chain 2, the latch moves the distance between address plates.

Abstract: 1,165,545. Variable speed friction gearing. H. AZUMA, and H. AZUMA. 5 Oct., 1966 [27 Oct., 1965], No. 44561/66. Heading F2D. In an automatic steplessly variable speed friction gear comprising a driving friction wheel 2, a driven friction wheel 4, and an idle wheel 13, the axis of rotation C1 of the idle wheel is deviated or deflected from its equilibrium position lying in a plane passing through the axis or axes of rotation of the driving and driven wheels to vary the speed ratio, under the action of a driving tangential force produced at the contact point between the idle wheel and the driven wheel, lying on a circular path on the driven wheel, due to the load torque applied to the driven shaft, an opposing force being applied to the idler wheel support to bring the idler wheel back to a new position of equilibrium after a ratio change. In Figs. 1 and 2, the idle wheel 13 is mounted in a frame 14 axially slidable along a shaft 16 supported at its ends by levers 5 having limited pivotal movement about a shaft 7 and loaded at their opposite ends by a weight 6 on a rod 9. The frame 14 is supported by crank arms 25, 26 passing between rollers (19), Fig. 3 (not shown), and 20 on the frame, and loaded to a central position by springs 35, 36, the compression of which is adjustable by screw rods 29, 30 to alter the torque characteristic of the variable speed means. In Figs. 9 and 10 (not shown), drive shaft (42) drives two intermediate shafts (41), each carrying a driving friction wheel (45) having an idle wheel (48) interposed between it and a single driven friction wheel (47). The idle wheels are supported in frames (49) axially slidable along a shaft (74) supported at its ends by adjustable springs (53). In Figs. 11-14 (not shown), the driving and driven friction wheels (83), (84) are formed with conical friction faces against which six spherical idle wheels (90) abut. The wheels (90) are mounted on shafts (89), the ends of which are mounted in radial slots in annular guide plates (85), (86) having limited rotational movement, one end of each shaft (89) also entering a helical slot (92) in a rotatable annular following plate (91). A lever (97) connects the plates (85), (86) at their periphery and permits relative angular adjustment thereof. The plates (85), (86) are spring loaded relative to rings (108), (109), rotatably adjustable to alter the torque characteristics of the change speed gear. In Fig. 19 (not shown), five spherical idle wheels (142) are mounted in guide plates (149), (150), between toroidal driving and driven friction discs (133), (134).

Title: Electronic amplifying assemblies
IPC: H03K5/02
Filed: 1971-09-24
Abstract: 1351037 Differential amplifiers, binary memory circuits INTERNATIONAL BUSINESS MACHINES CORP 24 Sept 1971 [29 Dec 1970] 44579/71 Heading H3T A differential sense amplifier, e.g. for a memory cell 10, comprises two, 2-stage amplifiers T1, T3 and T2, T4 having a common constant current supply T5 for their first stages, each amplifier having feedback from output to input and the amplifier outputs being coupled together by a resistor network, R3, R4, R5 to reduce coupling between the two sides of the amplifier. It is explained that variations at one input will cause variations in the other output due to the common current supply and the feedback therefore causes variations in the other input. This is compensated by the network. To write a "one" into the cell, negative data and clock pulses are applied to D1 and CLS and subsequently a negative pulse is applied to the write terminals. The current switch 14 turns off allowing T6 to conduct and set the cell to "one". To write a zero the sequence is repeated except that the data terminal D1 remains at its positive level so that T8 holds T6 off. The common emitter potential of switch 14 is however applied through T11 its base of T7 to render it conductive and thus set the cell to zero.

Abstract: 1282414 Internal pipe cutters FOSTER WHEELER JOHN BROWN BOILERS Ltd 25 Sept 1969 [25 Sept 1968] 45597/68 Heading B3C A tool for severing tubes comprises a body 12, a shaft 14, for insertion in a tube to be severed, which extends from, and is rotatable relative to, the body and has a cutter 16 pivoted to it at 18 and movable by an actuating linkage 28 from a position (shown in broken line) in which cutting tip 44 is wholly or mainly within the shaft to cutting positions in which the tip projects radially from the shaft for progressively cutting through the tube wall as the shaft is rotated and the tip is projected further from the shaft, the linkage 28 being movable axially of the shaft by actuating means which may, as shown, be a knob 30 in threaded engagement with the body 12. The shaft is rotated by means of a wormwheel 22 surrounding the shaft meshing with a worm 24 fixed to a drive shaft 26 journalled in the body 12 and driven by means (not shown). The linkage 28 includes a yoke 32 and a pin 34 extending between the yoke arms and slidable in a slot 36 in the cutter. Marks 40 on the knob and 42 on the body 12 indicate the position of the linkage and thus of the cutter. A guide ring 56 and a sleeve 58 keep the shaft axially aligned in a tube to be cut. There may also be a guide on the body 12 including tubular projections for engaging in the ends of tubes adjacent to that being severed. The sleeve 58 may form part of a weld torch used to weld a tube to e.g. a header, the sleeve being left in the tube when the main part of the torch is removed if the weld is found to be faulty. To prepare an edge for welding, a cutter (60) (Fig. 3, not shown) having two cutting edges at right angles to one another may be substituted for the cutter 16, the pivot pin 18 being readily removable. Air for cooling the cutter and removing swarf is supplied through inlet 50 and channel 48.
Patent GB-1073860-A (GB)
Title: Photographic shutter with electronic timing circuit
IPC: G03B7/083
Filed: 1965-11-01
Abstract: 1,073,860. Electronic shutter control. PRONTOR-WERK ALFRED GAUTHIER G. m. b. H. Nov.1, 1965 [Nov. 4, 1964], No. 46207/65. Heading G2A. A shutter has an electronic timing circuit comprising a first switch coupled to the shutter release, which closes the circuit, and a second switch, in parallel to the first, which is actuated by the shutter drive mechanism. Fig. 2 (not shown) is a diagram of the timing circuit, the time-delay being determined by the values of capacitor C and resistance R. The circuit is energized by closing switch 15, 16, which is effected when shutter release lever 9 is depressed. In parallel with switch 15, 16 is another switch 29, 30, which is closed by the running down of the shutter mechanism. Thus even if switch 15, 16 is opened again when the release lever is no longer depressed, the timing circuit continues to function while contacts 29, 30 remain closed. Fig. 1 shows the arrangement of the switches and the shutteroperating mechanism, in the cocked position. The shutter release lever 9 has an arm 9b extending through a slot 2a in base plate 2 to the camera release (not shown). One arm 9c, 9d of lever 9 holds back a spring-loaded lever 13 from urging spring arm 15 into engagement with contact pin 16. The tensioned driving disc 4 is latched against movement by arm 6a, 6b of spring-urged lever 6. Disc 4 has pivoted to it a driving pawl 18 which engages a lug 17a on a shutter-driving ring 17, and when disc 4 is allowed to run down (clockwise) pawl 18 drives ring 17 first one way and then the other, in known manner, to open and close the shutter blades. However, the complete running down of disc 4 is blocked by an arresting lever 20, which is in turn prevented from moving out of its blocking position by a further lever 23 whose position is controlled by a solenoid 28. When release lever 9 is actuated, lever 13 is released to close contacts 15, 16, so energizing the timing circuit. Lever 6 releases disc 4 to run down until blocked by lever 20, blocked in turn by lever 23 as solenoid 28 is now energized. Thus the shutter blades are held in the open position. Due to the "opening" movement of ring 17, a pin 17b which it carries allows spring contact 29 to engage contact 30, so that the circuit remains energized even if contact 15, 16 is broken by removing pressure from the camera release. When the timing action of the circuit elements eventually causes solenoid 28 to become deenergized, lever 23 is released, which in turn releases lever 20, and disc 4 is free to complete running down and so close the shutter again.
