Title: Improvements in power-driven typewriters
IPC: B41J23/12
Filed: 1955-12-23
Abstract: 814,400. Typewriters. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 23, 1955 [Dec. 29, 1954], No. 36935/55. Class 100(4) In a power-driven typewriter having a plurality of manually-operated keys 8 each operating an associated interposer 32 to establish a driving connection between power driving means 2 and a corresponding type bar, each key is connected to its associated interposer by a linkage associated with a cyclically-operable member 64 common to all the keys so that the linkage' is effective to operate the interposer only at suitable points in the operating cycle of member 64, whereby operation of two keys other than substantially simultaneously results in operation of the corresponding type bars at different ones of said selected points in the cycle of member 64. In the rest position shown trip latch 56 engages a lobe 78 or 76 on cam 54 and unwinds the spring of clutch 50 so that pulley 48 is rotated, free of shaft 52 carrying flutes 66, 68, by a pulley 44 rotatable with the power roll 2. When a key lever 4 is depressed:its finger 10 engages an ear 12 of a corresponding latch 14 and turns the latter about its pivot 16, so that hook 70 is moved into the path of flutes 66, 68, ear 24 is moved into position to operate on shoulder 26 of cam 28, and extension 20 rocks bail 22, the latter causing latch 56 to rotate, against spring 60, so that nose 62 is lifted out of the path of cam 54. Clutch 50 is thereupon operated, and pulley 48 rotates shaft 52. A flute 66, 68 then engages hook 70 and pulls latch 14 lengthwise, whereupon ear 24 rocks cam 28 and the serrated surface 34 engaging roll 2 causes lever 32 and the corresponding type bar to be rocked. As latch 14 is thus moved extension 20 slides off bail 22 and spring 60 restores the bail and moves latch 56 to block cam 54, and ear 12 is drawn beyond finger 10 whereupon spring 72 rocks latch 14 counterclockwise disengaging hook 70, and moving extension 20 into engagement with stop 74. If the key 8 is not released ear 12 engages finger 10 and prevents return of the latch 14. If a second key is depressed before latch 56 is restored by spring 60 the transverse movement of the latch 14 associated with the first key frees that latch from bail 22, but the extension 20 of the latch 14 associated with the second key blocks the bail, preventing the return of latch 56, and cam 54 makes a further half revolution during which flute 68 or 66 operates the second latch 14. The timing between type actions is therefore equal to one half of a revolution of shaft 52, and the timing is such that approximately 10 milliseconds elapses from the depression of the key until the next flute 66, 68 engages a hook 70. If two keys are depressed simultaneously or within 10 milliseconds side collision, but no head-on collision, occurs.

Abstract: 1471972 Inspecting pipe-lines COMPAGNIE FRANCAISE DES PETROLES ETUDES PETROLIERES MARINES SARL ATELIERS ET CHANTIERS DE BRETAGNE ACB SA COMPAGNIE MARITIME D EXPERTISES SA and COMPAGNIE GENERALE POUR LES DEVELOPPEMENTS OPERATIONNELS DES RICHESSES SOUS MARINES SA 22 Aug 1974 [27 Aug 1973] 36990/74 Heading F2P Apparatus A for checking the bore of a pipe T being laid from barge B on sea-bed F comprises a frame 1 having a domed movable part 2, which responds to deviations in the pipe bore greater than a predetermined value and/or to an overpressure of water in direction opposite to motion of apparatus to activate locking 7 and sealing means 11. The apparatus is connected via cable 8 to barge B by means of swivel 5 and drawbar 26, passing through movable part 2 and connected to frame 1. Movable part 2 carries metal blade 18, with lip seal 12, inwardly movable under deviations in bore of pipe. When a predetermined deviation is exceeded blade 18 contacts electrically conductive plate 30 to energize solenoid 21 to activate, under compressed air, piston 25b which pushes stop plate 9 compressing springs 24. This releases latches 10 allowing locking parts 7, equally spaced around frame 1, to move under springs 3 to bear against the pipe. Due to the pull of the cable on frame 1 the apparatus moves until the annular section of part 2 locks against the deformation and seal 11 is sealingly compressed against facing plate 29 and pipe bore. The annular space between drawbar 26 and part 2 is sealed by nozzle 13 engaging housing 16. In this manner faults are detected and due to the circular configuration of locking parts 7 and seal 11 prevented from propagating. If a split occurs in the pipe and the pressure of water is sufficient to move part 2 compressing seal 11; by means of rods 17 connected to stop plates 9 and urged against part 2 by springs 24 the apparatus is locked and sealed in position. Frame 1 carries wheels 15 urged against pipe bore by springs 28. One of the wheels is connected to a rotary counter 19 which in the event of shearing of the cable 8 and recoil of the apparatus energizes the solenoid to anchor the apparatus in the pipe-line. The cable 8 may be attached to rods 17 with rod 26 operating stop 9. The cable may be dispensed with and the apparatus moved by fluid pressure acting on cup (35) attached to rear of frame (Fig. 5). The position of seal 11 may be altered to for example be compressed by locking parts 7.

Abstract: 983,584. Telegraphy. DE STAAT DER NEDERLANDEN, TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEURGENERAAL DER POSTERIJEN, TELEGRAFIE EN TELEFONIE. Oct. 16, 1961 [Oct. 19, 1960], No. 36995/61. Drawings to Specification. Heading H4P. In a two-way telegraph multiplex system characters are transmitted over each channel in time spaced relationship, and in successive groups per channel, it being arranged that one character in each channel cycle is distinctively marked, each group having its distinctive character in a different time position from the other channels. A method of attaining or regaining an in-phase relation between cooperating stations is described. A four channel system is described in which each group contains four 7-unit signals. On channel A the first signal is sent inverted and the other three signals normal. On channel B is sent a second group of four signals, all of these except the second being inverted. On channel C all signals except the third are inverted, and on channel D all signals except the fourth are sent normal. Each channel is thus distinguishable from the others. If there is complete loss of phase between cooperating stations the receiver distributer steps by one signal bit at each cycle until it is found that there is correct phasing within the groups of signals. However, the channels may be now out of phase and if this is found to be so the distributer is stepped by one group of 28 bits at each cycle until the channels are in phase. Complete loss of phase is detected by counting the number of marks during a 112 consecutive bits and if the number counted is 56 (due to the arrangement of the channels described above), but no service signal I has been detected, phase loss is present. Loss of channel phase is detected by considering the distinctive characters referred to above. When complete loss of phase is detected a series of service signals I is transmitted (equivalent to setting up procedure) until synchronization is attained. Specifications 912,252 and 936, 804 are referred to.

Abstract: 835,907. Circuits employing bi-stable magnetic elements. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 4, 1956 [Dec. 7, 1955], No. 37038/56. Class 40 (9). [Also in Groups XIX and XL (c)] In a circuit employing a transistor memory device, each device is coupled to a saturable core which in turn is connected to a further transistor. Assuming free charge carriers have been established in the base region of transistor 45 by applying a negative pulse thereto, a subsequent clock pulse K1 applied to the collector circuit of the transistor causes current to flow in the emitter-collector path to magnetize the core 47 in one sense. The next clock pulse K2 provides a read-out facility so that a current is fed through winding 49 and isolating diode 50 to establish a state of free charge carriers in transistor 51. The next clock pulse K1 is effective in winding 53 to cause current flow in the emitter-collector path to magnetize core 54, any residual charges being swept out by clock pulse K3 fed through diode 52.

Abstract: 1,072,995. Cleaning films by air flow. E. I. DU PONT DE NEMOURS & CO. Sept. 1, 1965 [Sept. 3, 1964], No. 37403/65. Heading B5B. Particles are removed from the surface of a shaped article such as a film to clean it by exposing the film to a cleaning zone, creating aerodynamic shock waves in the cleaning zone by passing air having at least one sonic velocity at a pressure P 1  to a lower pressure P 0  when the ratio P 0 /P 1  is no greater than 0À528, and directing the shook waves across the surface of the film. The apparatus used includes means to support the film, and nozzle means for producing shock waves from a flow of air having at least sonic velocity, the nozzle means being located with respect to the film to allow the shock waves to flow upon the surface of the film. As depicted in Fig. 1 (not shown), a web 10 of film travels around a support roller 11 with the surface to be, cleaned outwardly exposed. Adjacent to the supporting roller is located a nozzle housing 13 consisting of a plenum 14 connected to a source of compressed air and a nozzle section 15 which extends to at least the width of the web surface to be cleaned. The nozzle section can have various configurations provided that sonic or supersonic air velocity be obtained when the air is discharged from the nozzle to form a jet 16 which impinges on the web at the line 12 and then flows upwards and downwards over the surface of the web away from the line 12 in a complicated aerodynamic shock-wave pattern. These shock waves dislodge the very fine particulate impurities clinging to the web, including particulate matter held to the web with strong electrostatic force. To prevent recontamination of the web the particulate matter dislodged from the web may be removed from the vicinity by a vacuum system. This may comprise a vacuum housing 17 which fits closely around an area of web on the support roller 12 so that a slight flow of atmospheric air will flow from outside the housing into the vacuum chamber 18 which is connected to a vacuum source.
