Title: Traverse control arrangement for print head drive
IPC: B41J11/14
Filed: 1972-06-15
Abstract: 1338351 Control of printers CREED & CO Ltd 15 June 1972 28058/72 Heading G4H The printhead of a serial printer is moved to a new location by a stepping motor 10 controlled by a circuit which produces a train of pulses separated by intervals which first decrease and then increase. Pulses from a clock 6 are fed to a shift register 1, outputs from stages 1, 5, 8, 11, 14, 18 thereof being fed in turn via gate 7 to a counter 8; a sequence of six signals from 8 is applied over lines 8a-8d in turn to windings 10a-10d of the motor, the spacing between the signals being such as to allow for acceleration then deceleration of the printhead as it moves to its new position. The output from stage 18 of register 1 is fed back to stage 1 and to gates 2-5; a switch 3 is normally closed so that a "1" in stage 18 inhibits gate 5 to stop the motor (with the printhead in its new position). To move the printhead again, switch 3 is opened to enable gate 5 whereupon the "1" in stage 18 is transferred to stage 1 and is shifted through the register as before.

Title: Travelling wave amplifier discharge device
IPC: H01J23/087
Filed: 1947-10-22
Abstract: 669,473. Travelling-wave tubes. WESTERN ELECTRIC CO., Inc. Oct. 22, 1947 [Oct. 22, 1946], No. 28258/47. Class 39 (i). In a travelling-wave tube the highfrequency wave travels along a helix 2, Fig. 2, and the helix 2 is supported and spaced from the tube wall by insulating-rods 15. Magnetic coils 23, 24 focus the beam, coil 24 being enclosed in a magnetic shield 25. The wire of the helix may be of steel or molybdenum. Alternatively it may be of high-loss material such as iron or an alloy which may be plated at both ends only or along its whole length with low-loss material such as copper or silver or may be unplated, in order to provide a desired uniform or non- uniform attenuation along the length of the helix and so to prevent any tendency to selfoscillation. Another way of introducing attenuation is to surround the central portion of the helix with a cylinder 36, Fig. 4, of loss material such as a mixture of ceramic and metallic materials. The input and output are injected and removed by wave-guides 3, 4, Fig. 2, coupled to the helix by strips 7, 9 designed to give a good impedance match and integral with short cylinders 6, 8. Cylinders 6, 8 may be a quarter-wavelength long and together with shields 10, 11 form open-ended low-impedance lines. A shield 12 extends between the waveguides 3, 4. Cylinders 6, 8 are positioned by ceramic spacers 13, 14 and have circumferential notches to receive the rods 15 which may be of a ceramic material containing zirconium oxide. The indirectly-heated cathode 16 is positioned in the aperture of focusing electrode 17. Accelerating electrode 18 and collector 19 are also provided. The cavity resonator 26 is resonant at the mid-frequency of the band and serves as a choke to prevent leakage of highfrequency energy along the lead to the helix from D.C. source 22. It is stated that the wave velocity is slightly less than the beam velocity. In Fig. 4 the rods 15 are in two parts on either side of the cylinder 36, the latter having circumferential notches to receive the ends of the rods remote from cylinders 6, 8. In another embodiment, Figs. 8, 9 (not shown), further magnetic focusing coils are provided, one of the coils surrounding the electron gun which is made of non-magnetic material. The coils are arranged to produce a uniform field over the whole length of the discharge device. In the form of Fig. 9 (not shown), the envelope is uniformly slender throughout its length and has no enlarged portion. Specifications 669,474 and 652,155 are referred to.

Title: Cross-laminated film material and methods of producing such material
IPC: B32B27/00
Filed: 1970-06-12
Abstract: 1316640 Cross-laminated films O B RASMUSSEN 12 June 1970 [13 June 1969 8 July 1969] 28479/70 Heading B5N Cross-laminated film material comprises two oriented polymer films laminated together with their directions of orientation crossing by means of a bonding film there being three substantially uniformly distributed bonding systems, namely (a) the bonding layer is strongly bonded to the one oriented film (the first) but not bonded or weakly bonded to the other (b) the bonding layer is not bonded or weakly bonded to the first oriented film but strongly bonded to the other, and (c) the bonding layer is not bonded or weakly bonded to both oriented films, the areas of the different bonding systems being immediately adjacent with one another with each area (c) generally immediately between areas (a) and (b). The oriented films may be of high density polyethylene and the bonding layer of low density polyethylene. Alternatively the oriented films may be of iso- or syndiotactic polypropylene, polyamide, polyethylene terephthalate, polystyrene, polyvinyl chloride or polyvinylidene esters and the bonding layer may be of high density polyethylene softened by addition of elastomers, soft copolymers of vinylidene chloride, polycaprolactam, polyethylene terephthalate, block copolymers of propylene containing elastomer links, block copolymers of butadiene and styrene, highly plasticized polyvinyl chloride or vinyl chloride-vinyl acetate copolymers. The strong bonds may be produced by thermowelding, by means of a solvent or by means of a two component adhesive and the weak bonds may be produced by means of a pressure sensitive adhesive of low viscosity, e.g. a soft putty comprising a mixture of a material of oily consistency with a finely dispersed powder. The oriented films may be printed with adhesive in the desired pattern of bonds and bonded together with the intermediate layer of unoriented material which may be extruded directly on to them in the nip of laminating rollers. Alternatively the oriented films may be bonded together by extruding the bonding layer on to one of them, effecting lamination by applying variable pressure with rollers at least one of which has an embossed surface and simultaneously or subsequently laminating the other films to the bonding layer. Using this method a bonding layer may also be laminated to the other film using variable pressure prior to laminating the oriented films together or the molten bonding layer may be extruded between the oriented films which are laminated together by applying variable pressure.
