Abstract: 1,226,002. Vehicle lighting systems. B. NORDBERG. 8 March, 1968 [8 March, 1967], No. 11386/68. Heading F4R. [Also in Division H2] A system of individual units for lighting-up defined portions of the field of vision in front of a road vehicle comprises one or more longrange units (which may be supplemented by a headlamp unit), a short range unit and a position indicating unit, light from each long-range unit which is concentrated into a horizontally narrow beam whereby it illuminates a long narrow strip of distant roadway extending in the direction of travel, performing a continually oscillating movement laterally. The shortrange lighting produces one or more patches of close-range illumination on the roadway wider than that produced by the long-range unit(s) and extending at right angles to the direction of travel. Fig. 2 shows the light distribution produced by the system. Two long-range beams which execute the oscillating movement produce illuminatiated areas 1, 2, two close-range beams illuminate an area 13 in which there are two transverse areas 9, 10 of concentrated light and position-indicating beams produce two narrow lines of illumination 14, 15 parallel to or aligned with the sides of the vehicle. The oscillating long-range lamp may be mounted in a common casing with two short-range lamps, the casing being closed by a recessed window having refractory points in front of the latter lamps, Figs. 9, 10, 11 (not shown). The units of the oscillating lamp are provided with elliptical paraboloidal reflectors; the lamp also has a refractory window which comprises a plurality of refracting elements, having suitable cylindrical components concentrating the light into lines, these being vertical in the long-range lamp and horizontal in the other lamps. Two forms of refracting element are described, Figs. 12-15 (not shown). The oscillation may be produced by mounting the reflector 29, Fig. 16, on vertical bearings 38, 39, the oscillation being produced by an arm 41 carrying a permanent magnet 45 at one end and engaging one of the pivots 39 at the other, the magnet 45 swinging between an electromagnet 46 and a fixed magnet (47). Current is supplied to the coil (54) of the electromagnet through conductors 52, 53 and a make-and-break circuit operated by an arm on the pivot 38.

Abstract: 1,228,430. Photographic film packages. POLAROID CORP. Feb. 27, 1969, No. 10634/69. Heading G2A. Photographic film units, e.g. of the selfdeveloping type for use with a self-developing camera, has an opaque envelope 14, 16 including an opening at one end and being releasably sealed at 72 adjacent another end thereof and along the longitudinal margins 18a, 18b thereof, the other end of the envelope including a pair of tabs 22, 24 each of which is integral with, and extends from, an envelope wall whereby after a photo-sensitive sheet has been withdrawn through the opening for exposure and subsequently reinserted to complete the processing of the exposed sheet, the sealed portions of the envelope are unsealed by pulling the two tabs in opposite directions. One envelope wall has attached thereto via a retaining strip 64, an image-receiving sheet 58 and a masking sheet 62 having a rectangular aperture 60 for defining the image area. The envelope walls 14, 16 are sealed by longitudinal strips 18a, 18b so that a photo-sensitive sheet 28, having a clip 20 at one end and a pod 52 of processing fluid at the other, may freely slide in the envelope from the initial position shown to an exposure position, Fig. 2 (not shown). The film units are preferably used in conjunction with the film holders described in U.S.A. Specification 2, 933, 993 or in Specification 1, 228, 429. In use, the unit is slid into a suitable holder attached to a camera, a releasable detent member (42) Fig. 3 (not shown) being operated to engage clip 20 so that upon removal of the unit the photo-sensitive surface is retained in the camera in an exposure position, the unit being removed until a transverse strip (46) Fig. 2 (not shown) mounted on the unit engages a further detent device (48). After exposure the unit is again slid into the holder, the detent devices (42), (48) operated to permit removal of the unit from the holder between pressure rollers which fracture the pod of processing fluid and spread a layer of fluid between the sheets to effect processing, the thickness of the layer being determined by spacer strips 66. After removal, tabs 22, 24 are pulled to break the seal 72 and tear the strips 18a, 18b to expose the completed print.

Abstract: 1,250,428. Weighing apparatus; photo-electric apparatus. L. OERTLING Ltd. June 5, 1970 [June 5, 1969], No.28573/69. Headings G1A and G1W. In a top-pan balance comprising a balance beam 11 on which a pan carrier 15 is pivotally supported to carry a pan 18 above the beam 11, a stabilizing weight 24 mounted below the fulcrum 13 of the pan carrier 15 is movable horizontally relative to the pan carrier, in a direction normal to the axis about which the latter is movable, by automatic means responsive to angular displacement of the pan carrier from the vertical, to restore the carrier to the vertical position. The weight 24 is in the form of a nut prevented from rotating by engagement of a lug 23 with a bracket 22, and threaded on a screw 21 drivable by a reversible electric motor 20. A vane 40 on the pan carrier 15 impinges on the light beam from a lamp 41 to a photo-cell 39 (a photo-sensitive resistance) connected in a Wheatstone bridge circuit which controls energization of the motor 20 via an amplifier 32. The vane 40 is shaped so that if the pan carrier remains vertical during pivoting of the balance beam 11, the illumination of the photo-cell remains constant. Movement of the pan carrier 15 is damped by an eddy current brake comprising an electrically conductive vane 42 on the carrier extending between a pair of permanent magnets 43. Ring weights (not shown) normally suspended on the pan carrier 15 are removed selectively until balance is achieved. An image of a transparent scale on the balance beam 11 is projected on to a screen for reading to fractions of the smallest weight. In a modification the vane 40 is replaced by a plane mirror which reflects the light beam on to the photo-cell. Alternatively the photo-electric system may be replaced by a capacitance transducer or a differential transformer responsive to angular movement of the pan carrier.

A spring 20 biases the unit relative to the path of a web (not shown) moving thereover so that the web, which normally has one edge close to the adjoining edges of rollers 26, 28, is urged outwardly until roller 28 begins to be turned by the edge of the web ; this action causes the pinion 29 to rotate, whereby the whole unit swings about the pin 14 in a direction to cause the edge of the web to move inwardly. As soon as the web moves clear of roller 28, the pre-loading action of spring 20 becomes effective again, and the shaft 16 is restored to its original position to ease the web outwards once more. Thus the edge of the web is maintained approximately in line with the division between rollers 26 and 28. Bobbins 42 between adjacent rollers prevent unwanted foreign matter from entering the bearings of the rollers.

Abstract: 1296786 Laser gyroscope HONEYWELL Inc 11 May 1970 [14 May 1969] 22618/70 Heading G1A [Also in Divisions H1 and G4] In a laser gyroscope two beams of monochromatic radiation are directed around a closed path defined by mirrors 2, 3 and 4 in opposite directions. The light beams are detected via mirrors 6 and 7 by photo-detector 8. If the system is rotated a frequency difference is produced between the two beams which may be detected in the form of a shifting fringe system. In order to prevent the two frequencies locking together in the laser, the optical system as a whole is oscillated so that the frequency difference between the two beams is always sufficient to prevent lock-in. The detector circuit 13 is designed so that the output appears on line 14 or line 15 according to the direction of rotation of the system. The pulse train output on lines 14 and 15 are fed via gates 29 and 30, which are NAND gates to a reversible counter 17. In this way the count recorded on counter 17 is the difference count between lines 14 and 15 and represents the next rotation in any one direction. The pulse trains are counted by counter 17 for a fixed number of oscillation periods of the rotating system, so that the next reading on counter 17 corresponds to true rotation and not the imposed oscillatory rotation. This gating is achieved by means of control circuit 16 which controls the switching of gates 29 and 30. The gates 29 and 30 being held open for a fixed number of cycles by means of counter 32, and latching circuit 33. The logic units employed in this circuit are NAND gates. Specification 1116416 is referred to.

Abstract: 1310582 Measuring frequency J E READ 24 March 1970 14358/70 Heading G4H Recognition of the frequency of an input signal is achieved by applying the A.C. input signal via terminal 1 to amplifier 2 which converts it to a series of pulses. These pulses pass through a gate 3 which is controlled by means of a clock 4 so that pulses are only passed thr ough the gate for a preset period. The pulses then pass through a pulse divider 6 and are recorded in a binary counter 7. At the end of the timing period, gates 16 to 19 are enabled, these gates acting as a decoder unit. If the count stored by the counter corresponds to a binary 4, 5, 6, 7 then a signal is stored on the appropriate one of memory 20 to 23. These memories in turn control control switches 11. A lockout device 24 is provided to inhibit the operation of the clock for a period after decoding of the counters so that only one frequency measurement is made during the period in which a continuous signal is detected by the apparatus. The apparatus may be used for controlling the operation of a toy or model. The incident signal may be a sound of a given frequency an electrical signal detected by an induction coil.

Abstract: 1317055 False twisted yarns TURBO MACHINE CO 12 June 1970 28460/70 Headings DID and D1F Yarn is processed by first applying false twist to the yarn and then applying real twist to the yarn at a selectively variable rate. In a preferred embodiment, two yarns Y 1 , Y 2  are pretwisted together and passed in contact with a heater 11, the two yarns being false twisted by following the pretwist and untwisting. The false twisted yarns are separated at S and passed via guides and pulleys 13, 14, 23 and 24 to tension equalising nip rolls 25, 26. The separated yarns are then passed to a bobbin 41, 42 via a ring and traveller twisting arrangement whereby the relationship between the speed of rotation of the bobbin and the rate of feed of the yarn from the nip rolls determines the amount of twist imparted to the yarn. The ring 43 of each twisting station may reciprocate up and down independently or may be attached to a ring rail 45 for simultaneous motion. Similarly, the speed of rotation of each bobbin may be controlled independently or all bobbins may be controlled in unison.
