Title: Scanning devices
IPC: G02B5/09
Filed: 1972-01-25
Abstract: 1419619 Optical scanning REDIFON Ltd 23 Nov 1972 [25 Jan 1972] 3429/72 Heading H4F An optical scanning system comprises a rotatable mirror drum 10 together with an arc of combinations 15 each of a lens 16 set at substantially its focal distance from the reflecting face of the drum and a roof prism 17 and which serve to receive a light beam 14, 14<SP>1</SP> after reflection at a face of drum 10 and to redirect it as a beam 14<SP>11</SP> to the same face, whereby the final beam 14<SP>111</SP> is deflected in the same sense as, and at four times the angular rate of, the rotation of the drum. In Fig. 1, the beam 14 is at a slight angle to the general plane of the system, and as the beam 14<SP>1</SP> traverses each roof prism it provides a corresponding line scan. The scanning of beam 14<SP>111</SP> is centred about the beam 14 when seen in plan view, but is vertically displaced therefrom. Fig. 2 (not shown) indicates how, by suitably relating the positions of combinations 15 with respect to the angles between adjacent faces on the drum 10, the light loss which would otherwise occur when a corner of drum 10 crosses beam 14 is eliminated. During that period, beam 14 is split into two beams incident on separate combinations 15, but the beams recombine when again incident on the drum corner to form a single scanning beam 14<SP>111</SP>. By this means it is possible to increase the width of beam 14 so that it is equal to, or greater than the width of individual faces of the mirror drum. A similar principle may apply if beam 14 falls on more than one corner of the drum simultaneously. The beam 14 may extend from a light source, e.g. a laser, or extend towards a stationary photodetector. It may be of ultra-violet or infra-red radiation. The system is said to be of use in surface inspection apparatus, for visual displays or video signal generation, and in apparatus for data recording and retrieval. Tracking of moving radiant areas is also mentioned.

Patent GB-746798-A (GB)
Title: Improvements in or relating to wave attenuating arrangements
IPC: H01J23/30
Filed: 1954-02-08
Abstract: 746,798. Traveling wave tubes. TELEFUNKEN GES., [formerly TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE]. Feb. 8, 1954 [Feb. 7, 1953], No. 3564/54. Class 39 (1). A travelling wave tube of the helix type is provided with loss material in the form of a strip-like layer of uniform thickness deposited on an insulating member, preferably a helix supporting rod, the layer having a linear central portion and end portions several wavelengths long extending progressively away from the helix so as to provide a progressive reduction of the attenuation, due to the rapid decrease of the high-frequency field with radial distance from the axis, and so to prevent reflection. In one form, Fig. 3, one of the three ceramic rods 11, 11a, 11b supporting the helix 3 carries a strip of loss material which contacts the helix along its central portion 12a and is bent away from the helix at its ends 12b in spiral arcs. If the rod 11 has a sufficiently large diameter, generally greater than the helix diameter, and is made of a suitable ceramic material, e.g. having a dielectric constant greater than 6, it is possible to make the line substantially dispersionless, i.e. with constant phase velocity over a wide frequency range. This is because when # increases the field spreads further radially and the retardation due to the rod material increases, which counteracts the increase of phase velocity which normally results when A is increased and similarly for a decrease in A. Thus the D.C. voltage of the helix can be kept constant. The ends of the attenuating layer are preferably substantially outside the high frequency field, so as to reduce reflection to a minimum. In a modification, Fig. 4, each of the three ceramic rods 11, 11a, 11b has an attenuating strip coating 12b. There may be a fewer or greater number of rods than three and the rods need not be of circular section, e.g. these may be three rods of rectangular section, Figs. 5, 6 (not shown). It is stated that the invention is applicable to wave retarders and other line structures in general. A prior art travelling- wave tube in which the insulating rods or tube carrying the helix have a layer of loss material the thickness of which tapers at the ends, is referred to.

Title: Improvements in or relating to the treatment of filamentary tow
IPC: A24D3/02
Filed: 1961-05-04
Abstract: 986, 393. Treating fibres. EASTMAN KODAK CO. May 4, 1961 [May 5, 1960], No. 3949/64. Divided out of 986, 391. Headings D1F and D1L. A jet device for use in processing tow comprises a tubular entrance member, a flared exit member, a chamber therebetween containing an orifice plate and inlet means permitting gaseous fluid to be forced under pressure into the chamber and through the orifice plate towards the exit member. Preferably the device includes resilient means adjacent the exit member for retarding the exit of the tow whereby a build-up of tow occurs which thus acts as a filter for the gaseous fluid leaving the jet device. In the embodiment shown in Fig. 3, the jet device consists of an outside shell 10 containing several inner members 11,13,14 held by plugs 12,15. A passageway 16 extends through the device so that multi-filament crimped tow may pass therethrough. The conical outer surface 19 at the lower end of member 11 and the tapered surface 20 of the thin orifice plate 13 together form an annular orifice for metering the air flow from openings 24, 24<SP>1</SP> into a Venturi tube member 14. The air flowing through said annular orifice impinges on tow passing through passageway 16 to produce an opening or blooming effect on the tow. This blooming effect is further enhanced by providing a plurality of flat spring fingers 26, 26<SP>1</SP>, 26<SP>11</SP> around the outer surface of Venturi member 14 which have the effect of partially retarding the tow as it emerges from the jet. The retarding force acting on the tow can be adjusted by the position of clamp ring 28. The jet device is used in the manufacture of tobacco smoke filter as described in Specification 986,391 and plasticizer may be added to the tow in the form of an aerosol generated in an "atomizer" incorporated in the air supply system to openings 24, 241. Alternatively the plasticizer may be introduced directly into the jet and on to the tow being processed therein by a plurality of metering gear pumps supplying capillary tube probes located in the tow entrance tube 11 and/or in the Venturi member 14. In a further embodiment the plasticizer may be applied to the tow as described in Specifications 986,392 and 986, 395. Specification 986,394 also is referred to.

Abstract: 760,107. Automatic reclosing circuitbreakers. GENERAL ELECTRIC CO. Feb. 13, 1953 [Feb. 15, 1952], No. 4113/53. Class 38(5) An automatic reclosing switch comprises a fixed contact 22 and a contact arm 24 connected in the transformer primary circuit, the arm 24 being freely pivoted on a shaft 28 and having a slot 27 engaged by a pin 47 on a disc 45. The disc 45 is fixed to a shaft 37 which may be driven by a spring 39 through gears 43, 44. Rotation of the disc 45 is normally prevented by a latch 55 which has arms 56, 57., alternately engageable with a tooth 46 on the disc. The latch 55 is fixed to the shaft 28 to which are also fixed arms 54 biased by a spring 58 into engagement with adjusting screws 53 on bimetallic elements 48, 49 connected in the transformer secondary circuit. In the event of overload, one or both bimetallic elements deflect upwardly and turn the arms 54, shaft 28 and latch 55 to release the tooth 46. The spring 39 then turns the disc through half a revolution in a clockwise direction the tooth 46, then abutting the latch arm 56 and the pin 47 pivoting the contact arm 24 about the shaft 28 to open the contacts. When the bimetallic elements cool, the arms 54 are returned to their initial position by the spring 58, so turning the latch 55 to release the tooth 46. The disc 45 then turns through a further half revolution and recloses the contacts 22, 24. Should the overload condition remain, two further reclosing operations are performed before the switch is locked open by a pin 59 on the gear wheel 43 abutting a frame 36 and preventing further rotation of the shaft 37 by the spring 39. An arm 41 is provided for resetting the switch, the arm also serving as an indicator to indicate the position of the switch and the number of operating sequences performed.
