Abstract: 1,258,786. Keyboards for printers. TELETYPE CORP. 23 Jan., 1969 [29 Jan., 1968], No. 3742/69. HeadingB6F. A keyboard for a teleprinter includes a plurality of key levers 55 each associated with an encoding device, depression of the key lever acting first to move the encoding device to an operative position and subsequently to disengage the key lever from the encoding device so that the encoding device can return to an inoperative position. Each encoding device comprises a shutter 106 having tabs 112 capable of closing light paths 110 and a universal tab 113 capable of closing a light path 111. On depression of the key lever 55, a lever 90 is caused to pivot at 92 and bring a finger 95 into engagement with a pin 114 on the tab 113. The shutter 106 is thereby rotated against a spring 116 for further depression of the key lever 55 until the arcuate paths of travel of the finger 95 and pin 114 diverge, when the shutter 106 is released. At the time of release, the tab 113 blocks the light path 111 but the tabs 112 have passed their respective light paths 110 (Fig. 3A, not shown). In this position, light detectors are primed so that as the shutter returns, the light passing along the paths 110 is detected when the path 113 becomes unblocked. At this moment, the tabs 112 are blocking their respective light paths 110 (Fig. 3B, not shown), and a coded signal is generated. Repeat action.-The key lever 55 is formed with a tab (120), Fig. 2 (not shown), capable of blocking a light path 121, Fig. 3, under full depression of the key lever. While the light path 121 is blocked, the character corresponding to the key lever depressed is repeatedly generated. If the character is not required repeatedly, the tab (120) may be broken away from the key lever.

As shown, both the leading and trailing edges 5, 6, respectively, of the projection 3 are bevelled. The projection 3 extends into a slot between units 7 of a roller carrying a thermoplastic film web past the blade 1, the units 7 being separated by a spacer 8.

The neutral line of tension 10, i.e. the line through the ends of the blade about which the strains resulting from the attachment of the blade at itstwo ends, under longitudinal tension, are balanced, lies wholly within the body of the blade. The blade may be made of a nickelchrome alloy. The blade may be used for dividing flattened tubular films into at least two sections or for slitting a single thermoplastic layer, e.g. to prevent fraying of cut edges of a woven fabric or to form bead edges to strengthen the cut edges of slit films.

Title: Electrophoretic image reproduction device
IPC: G02F1/167
Filed: 1970-04-23
Abstract: 1313412 Matrix displays MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 23 April 1970 [23 April 1969 (2) 12 June 1969 (4) 29 July 1969] 19611/70 Heading G5C [Also in Divisions H1 and H4] A display device comprises a colloid layer and means for applying an electric field thereto so that the colloidal particles move electrophoretically to one side of the layer thereby varying the optical reflectivity of the layer. The field may be applied by two electrodes adjacent the entire major faces of the colloid layer, or one of the electrodes may be shaped or segmented, Figs. 5 and 6 (not shown), or both electrodes may be in the form of orthogonal sets of parallel strips, Fig. 7 (not shown), e.g. for sequential scanning purposes. An insulating coating between the electrode and colloid improves the operating life of the device, Fig. 11 (not shown). Alternatively the electrode may be placed, permanently or temporarily, on the outer surface of a container for the colloid, Figs. 6b and 8a (not shown), e.g. being shaped, or an electrode "pen". The electric field may also be applied using ions or a beam of electrons which scan an insulating plate, or a conductor mosaic plate, adjacent the colloid, Fig. 9 (not shown). The display produced may be erased in each case by application of a direct or alternating field, e.g. using a conductive roller on one surface of a housing for the colloid, or by directing charged particles thereto. The colloid may comprise particles of a single type, or of types having different mobilities or charge polarities, in a closed or colourless medium. Thus a grey colloid formed of black and white oppositely charged particles will give white and black opposed surfaces when a field is applied. The colloid layer may include a layer of porous material such that the colloid particles may pass through but which obscures the particles when they have passed through, Fig. 2 (not shown). In such a device, on reversing the applied field, the colour may change from that of the colloid to that of the porous layer. The colloid may also be contained in a layer of porous material which serves to space the electrodes apart, particularly if the device has flexible walls, and which may be colourless or be constituted by the coloured porous layer mentioned above if it is of a suitable thickness, or a spacer may be incorporated which divides the layer into individual cells. Figs. 12 and 13 (not shown). A display panel , Fig. 12c (not shown), uses such a spacer together with orthogonal sets of strip electrodes. Successive cells have colloids capable of giving red, green and blue reflectances, respectively, or are provided with red, green and blue filters and have colloids capable of giving black or white reflectances. The display may be "fixed" if the suspension medium is suitable, e.g. by heating a thermosetting medium, by cooling a molten medium, or by evaporating off solvent which has previously been used to soften the medium. Details of materials used for the colloid and in the construction of the device are given in the Specification.
