A flexible planographic printing-plate for imaging by means of a carbon ribbon, and particularly for printing on cheques with mag. netic ink, comprises a cellulosic sheet, a pianographic coating of a pigmented water-insoluble hydrophilic polymer and an intermediate barrier layer of a heat-curable pigmented elastomeric latex-derived hydrophobic polymer. The sheet may be paper, lightly sized and coated with a composition of casein and clay with some urea formaldehyde added. For the planographic coating a polyvinyl alcohol type adhesive, e.g. a highly hydrolysed alcohol, may be used, or hydroxy-ethyl starch, carboxy-methyl cellulose, modified starches, polyacrylic acids, and carboxy-methyl-ethyl-cellulose may be employed. The pigment may be calcium carbonate and English coating clay dispersed in water. A small amount of melamine formaldehyde solution plus a water solution of zinc acetate are also incorporated in the coating. Latices based on acrylic copolymers are suitable for the barrier layer and may be cross-linked with a reactive and thermosetting resin, e.g. urea or melamine formaldehyde, to improve the resistance to water. Other substances that may be used are styrenebutadiene latex, vinylidene chloride latex and butadiene-acrylonitrile latex. The pigment in the layer may be clay. The sheet may have a layer similar to the barrier layer on its under face to prevent curling. An indentation test for the completed plate is specified. The imaging is performed by a typewriter using a film type of ribbon of polyethylene or acetate. Specification 633,747 is referred to.

Abstract: 1,079,023. Rotating waveguide couplings. COMPAGNIE FRANCAISE THOMSON HOUSTON - HOTCHKISS BRANDT. Oct. 23, 1964 [Oct. 25, 1963], No. 43425/64. Heading H1W. A single or multi-path rotatable coupling comprises one or more inputs, e.g. 103, 104, Fig. 2, connected by means of a rotating annulus 100 to an output or to respective outputs, e.g. 103<SP>1</SP>, 104<SP>1</SP>. The annulus carries on one end surface a circular array 105 of probes 1, 2, 3, 4, 5 &c. connected respectively by transmission lines 106 1 , 106 2  &c. (not all shown) to a further circular array 105<SP>1</SP> of probes 1<SP>1</SP>, 2<SP>1</SP>, 3<SP>1</SP>, 4<SP>1</SP>, 5<SP>1</SP> &c. on the other end surface, the second array of probes being numbered in the opposite direction to the first array. The connection between the probes is invariable, i.e. 1 is always connected to 1<SP>1</SP>  and 2 to 2<SP>1</SP> and so on. Slots 7 permit passage of the probes through the sides of the waveguides. The spacing of the probes is such that each waveguide always contains one or more probes, the widths of the waveguides preferably being made equal to a multiple of the probe spacing. If the sets of input and output waveguides rotate with respect to each other at an angular velocity N, it can be shown that the inputs remain coupled by the lines 106 to the outputs in one-to-one correspondence provided that the annulus rotates at a velocity N/2. A method of ensuring the required relative rotations may comprise a planet wheel journalled to the annulus and meshing with sun wheels fixed respectively to the sets of input and output waveguides. It is necessary that all the transmission lines 106 be of equal length and a configuration for ensuring this is indicated in Fig. 6 (not shown), where it may be seen that the axial and circumferential runs of the lines are arranged to have the same aggregate length. A suitable construction may consist of a stack of annuli, each annulus having two parallel arcuate grooves in which are located inner conductors, apertures being provided at suitable intervals to provide for the axially arranged lengths of line. Alternatively, dielectric compensation may be used in a set of lines having unequal physical lengths. For multi-channel working, waveguides of different dimensions may be used, each output waveguide having, of course, the same dimensions as the corresponding input guide. Where high powers are involved, it is necessary to use simultaneously as many of the probes and transmission lines as possible. In a suitable coupling for this purpose (Fig. 8, not shown), a series of probes (105) move parallel to the axis of a tapered waveguide (160).

The conveyor 42 secured to the button holder clutch 80 is rotated in steps by the oscillation of toothed sector 68 which rotates a pinion 70 and. through a one way clutch, the clutch 80, reverse movement being prevented by an escapement 82. During rotation of the conveyor a button fed in at station A is urged by a stationary cam 160 into its recess where it is held by a spring 146. The orientation means 168 comprises a gear 181 and pin 174, the latter carrying two prongs (180 Fig. 6 not shown) for engaging the button's holes and being engaged by one end of a pivoted spring 184 the other end of which is engageable, when the support frame 36 and conveyor are raised, by an abutment 193, 194 mounted on the machine frame. In operation the pins 180 press against the upper surface of the button and pin 174 is rotated a minimum of 90‹ or 180‹ according to whether four or two hole buttons are supplied, during which rotation the pins engage the holes and continue to orientate the button in its recess. At the end of a cycle spring 184 pivots to raise pin 174 from the button which then is moved by the conveyor to the sewing position. At the end of a sewing cycle the device is raised but the work is maintained against the throat plate by the spring 204 secured below the support frame 36 to drag the button from the conveyor as that frame rises. The spring has a notch open in the appropriate direction so that the sewn button can be pulled away by the work as it is fed in the appropriate direction. An optional thread severing mechanism comprises cutter blades 258, 266 pivoted below the throat plate and operated by linkage 228, 230, 232, 250.
