Title: Multi-Coloured Ribbon System for Typewriters or Like Machines
IPC: B41J33/518
Filed: 1967-04-07
Abstract: 1,160,324. Typewriters. SCM CORP. 7 April, 1967 [26 April, 1966], No. 16083/67. Heading B6F. Multi-colour ribbon arrangement; fast winding feeding.- An ink-ribbon has a portion of its length one colour and another portion of its length a different colour and, at the portion of the ribbon where the different coloured lengths meet, is an abutment, e.g. a button 14, which actuates a ribbon reversing member 16 when half of the ribbon is on one spool, e.g. 82, and a further button, at the end of the ribbon attached to spool 82, operates a reversing member 66 when all the ribbon is wound on the other spool 96. To bring the other colour on the other half of the ribbon into use, a fast winding feed from a motor 102, Fig. 4, is used; this drives belts 104 and a shaft 100. The drive from this shaft to a ribbon feed shaft 22 is coupled by a belt 110 on a lever 106 actuated by a control key 114. The key 114 has two directions of movement according to which colour, i.e. which end of the ribbon, is required. The key 114 tilts a lever 126 one way or the other to operate the ribbon reversing mechanism but in both directions the belt 110 is tilted so the fast drive from the shaft 100 is coupled to the ribbon feed-shaft 22. Ribbon reversing, automatic.-The shaft 22 may be axially shifted to effect a drive to either the left or right-hand spool. For normal typing actions, a shaft 50 is rocked at each operation and a bail finger 20 rocks, clear of engagement with a step portion 42 on a conditioning lever 32. However, when a button 14 indicates the end of a particular colour length by its engagement with either reversing levers 16 or 66, the ribbon reversing mechanism is actuated so that the step portion 42 is engaged by the finger 20. This causes a fork 27 to rock clockwise and the shaft 22 is axially shifted by a disc 44 positioned between the fork. The reversing members 16, 66 which are engaged by the buttons 14 are formed of two parts sprung together so that when a different colour end of the ribbon is required the middle of three buttons 14, which is thinner than the buttons at either end, may pass through the levers. Ribbon guide.-The ribbon vibrator guide 89 is shaped at 90 to allow passage of the middle button 14.

Title: Improvements relating to mechanical relay mechanism
IPC: G04F3/02
Filed: 1926-06-26
Abstract: 281,350. Graseby, R. C. June 26. 1926. Clockwork actuation.- Mechanical detent mechanism for clockwork-controlled switches &c. comprises a number of escapement mechanisms cooperating with a stop and being reset directly by a cam, the arrangement being such that after one of the escapements is reset it is held in that position by the cam, whilst after a subsequent operation by another escapement, the former escapement is held reset by a trip lever. As shown, the arm 5 for moving the switch &c. is connected to the clockwork spindle 2 upon which are rigidly secured two cams 8, 9. the cam 9 being provided with a detent 24 and the cam 8 having a projecting tooth 10. Escapement spindles 12, 13 have flats 16, 17 cut in them and are adapted to arrest or release the cam tooth 10 when their corresponding arms 22, 23 lie on the cam surface or fall behind the detent 24. Movement of the arm 22 or 23 behind the detent 24 is, however, presented until one or other of levers 35 is tripped about the pivot 34, the trip levers having pin-and-slot connections 28 - - 31 with further arms 26, 27 carried by the escapement spindles 12, 13. The pin-and-slot connections are such that while, say, in the left-hand connection, the pin 29 abuts the edge of the slot 31, there exists a certain amount of loose play in the other connections. This arrangement permits slight actuation of one trip lever without affecting the escapement mechanism. An interlocking arrangement 41 further prevents both trip levers from being actuated at the same time. The trip levers are restored by light springs 39.

Title: Improvements relating to machine tools
IPC: B23Q15/00
Filed: 1969-03-31
Abstract: 1,246,215. Machine tool details. BABCOCK & WILCOX CO. 31 March, 1969 [14 June, 1968], No. 16663/69. Heading B3B. [Also in Division G1] In a machine tool the workpiece W, Fig. 1, is carried on a pallet 10, and moved between stations, so that at any station, the workpiece is machined by a rotating tool T, the applied torque of which is controlled by a controller C associated with a motor 16, so that when a predetermined torque is reached, a warning signal is produced, and when a greater predetermined torque is reached, the tool is retracted by a cylinder 15. Motor 16 may be electric or hydraulic, and slide actuating cylinder 15 may be replaced by a lead screw, rack and pinion, or ball screw, or a quill may be used instead of a slide and spindle 15, 14. Controller.-The controller comprises a torque sensor 25, Fig. 3, which produces a signal corresponding to the torque on the motor, and therefore on the tool. The signal passes through an AND gate 26 which also has a no load torque signal passing through, the signals then registering on an analog memory 27. As the tool engages the workpiece, the load increases, thus causing an increased instantaneous torque. The signals are subtracted in a summer 28, and then compared with a first reference signal in a comparator 29, and if the output of summer 28 exceeds, the reference signal, a warning signal is produced which energizes a warning light 30. The output of summer 28 is also compared in a comparator 31 with a second greater reference signal, and if the output is greater than the reference signal a second signal energizes a relay 32, which actuates cylinder 15, and the tool T is retracted. The instantaneous torque signal also passes to a rate of change detector 33 whose value is compared in comparator 34 with a reference signal, and if greater actuates relay 32. In a modification, signal comparison is referred to the nominal cutting load, a preset level of torque corresponding to a sharp tool, and a workpiece of normal composition, rather than to the no-load condition alone, by including a servo set potentiometer assembly (35), Fig. 4 (not shown). In a further modification, the functions of summing amplifier 28 are split between amplifier (28a) (28b), Fig. 5 (not shown). In another modification, provision is made, for retracting of the tool if a sufficient torque is not being applied, by including a time delay (40), and a comparator (42), which produces a signal when the load torque signal is less than a reference signal (3), Fig. 6 (not shown).
