Title: Improvements in or relating to an optical system and an apparatus for measuring displacements
IPC: G01B21/06
Filed: 1963-01-01
Abstract: 1,006,698. Electric selective signalling. RAYDOW LABORATORIES Inc. Jan. 1,  1963 [Jan. 19, 1962], No. 148/63. Heading G4H. [Also in Divisions G1 and G2] In apparatus for measuring displacement there are primary and secondary gratings, a mono-chromatic light beam illuminating a predetermined portion of the primary grating, means for superimposing an image of the primary grating on the secondary grating and for displacing the image according to the displacement to be measured. In the form of Fig. 1 the primary grating 23 is illuminated by a lamp 20, the light passing through a narrow band filter 21 and a condenser lens system. The image passes through a collimating lens 24 and is reflected from a mirror 25 through a lens 26 to fall on the secondary grating 27 as shown at 23a. A photo-cell 28 receives light passing through the grating 27. As the mirror 25 rotates through a small angle the image 23a moves over the grating 27 and induces a sinewave signal in the photo-cell 28. In modifications the image is projected through a halfrnirror at 45 degrees or a prism on to the displaceable mirror which returns it to the halfmirror for reflection on to the secondary grating at one side. In a similar form, Fig. 7, the image reflected by the half-mirror 30 is enlarged by a lens 35 and reflected by a mirror 30<SP>1</SP> on to a secondary grating 27<SP>1</SP> which is larger than the primary grating, corresponding to the enlarged image 23a. Rotation of mirror 25 gives photo-cell 28 to provide an output of a corresponding number of cycles. In the form of Fig. 3 an image of the primary grating 31 is projected by lens 24 on to displaceable mirror 25, reflected light being returned through lens 24 on to the secondary grating which is coplanar with the primary grating. As the mirror tilts the image of the primary grating sweeps over the secondary grating and photo-cell 28 generates a sinewave signal as before. For measuring linear displacement the primary grating 23, Fig. 9, is arranged with a halfmirror 30, and mirror 25 to project an image on to the secondary grating 27. The photo-cell 28 may be connected to a meter 45 the reading of which indicates the relative position of the image of grating 23 with respect to grating 27. A pivoted wedge 46 may also be provided to displace the image through the distance of one or more lines. In the form of Fig. 10, the primary grating 23a has lines in both directions at right angles and its image is projected on to X and Y secondary gratings. The displacement in the two directions is indicated by photo-cells 28a, 28b. The sinusoidal output from a photo-cell is applied to a Schmitt trigger to generate a square wave which is is differentiated to obtain positive and negative peaks. The latter are eliminated by rectification and the former pass to a counter for measuring the displacement or the speed of movement.

Title: Apparatus for punching tapes
IPC: D03C19/00
Filed: 1975-01-07
Abstract: 1485182 Selective punching apparatus EDOUARD DUBIED & CIE SA 7 Jan 1975 [14 Jan 1974] 618/75 Heading B4B [Also in Division F2] Apparatus for selectively punching a tape used to control, e.g. a knitting machine comprises a plurality of punches 23 freely mounted in a carrier plate 21 for co-operation with a die plate 6 and adapted to be actuated by a strike bar 10, feed means 62, 63, 66, 67 for feeding a tape through the apparatus, keyboard operated selectors 24, 25, for selecting the punches which are held in such selected positions prior to actuation of the punches by retaining means 58, 60, the retaining means being released at the end of the punching cycle. The punch carrier plate 21 is connected to the strike bar 10 which is raised and lowered during a punching operation by means of rods 15, 16 actuated by respective eccentrics 34, 38 mounted on a manually-rotatable shaft 29. The punch selectors 25 are pivotally mounted on a shaft 27 and each have connected thereto an interposer rod 24; the rods may be the same length and alternate ones connected to their respective selector 25 by one or other of slots 44, 45, Fig. 2. Upon operation of a selector, the rod is moved over its associated punch and the selector retained in this position by means of a projection 58 on a spring finger 60 engaging with a lug 56 formed on the respective selector. At the end of the punching stroke, a bar 59 is raised by cam actuated connecting rods 32, 40 to release the selected spring fingers thereby allowing all the selectors 25 to be returned to their inoperative positions by springs 53; alternatively, the selectors may be individually returned by releasing the respective spring finger 60 by means of a projection 61 provided on each finger. The tape is fed through the apparatus by means of pin wheels 62, 63, 66, 67 mounted on rotatable shafts 64, 65, the shaft 65 being rotated by means of ratchet-and-pawl mechanism 93, 94, Fig. 8. The pawl 93 is pivotally mounted on a lever 90 which is oscillated by a cam 36 secured to the shaft 29. The pawl may be disengaged from the ratchet 94 by means of a sliding lever 100 thereby enabling the shaft 65 to be rotated directly in the reverse direction by a handwheel (87), Fig. 7 (not shown). In a modification, Fig. 10 (not shown), the pin wheels are of hexagonal shape such that they can feed interconnected cords (133) instead of a continuous tape.

Title: Improvements in or relating to Synchronizing Systems
IPC: H04N1/36
Filed: 1967-01-05
Abstract: 1,162,348. Electric synchronous movements. MAGNAVOX CO. 5 Jan., 1967 [12 Jan., 1966], No. 654/67. Heading H2L. In facsimile or other equipment in which transmitting and receiving transducer yokes are driven by synchronous electric motors via intermediate " actuators," synchronizing pulses from the transmitter operate the receiving actuator so that its yoke is locked to the drive only when the drums are in phase synchronism. Prior to this the yoke is driven at some 90% normal speed via epicyclic gears and a centrifugal friction clutch 98. The synchronizing pulses are transmitted during an initial period only, determined by thermal switches at transmitter and receiver, and comprise a continuous black level signal interrupted when a magnet carried by the drum closes a stationary earthing switch at the datum position. Transmission is by frequency modulation of an audio oscillator by optical scanning means, the oscillator being coupled to a standard telephone handset. The intermediate actuator comprises an arm 112 carrying two coupled pawls 114, 116. 114 can engage any tooth in a wheel 120 (driven directly at synchronous speed) and 116 engages a detent 128 in a member 24 coupled to the yoke. Initially, the pawl 114 is engaged and the actuator arm 112 is carried round until the pawls reach a datum position defined by the armature of an electromagnet (not shown). While the magnet is energized the pawls are disengaged and the arm 112 held, but on arrival of a synchronizing pulse the magnet is released and the pawl 114 again engages the wheel 120, but this time in phase synchronism with the transmitter. When the second pawl 116 meets the detent 128 the drive is transmitted to the yoke. Since the speed of the centrifugal clutch 98 depends on the difference between the speed of the yoke and synchronous speed, this now disengages and synchronism is complete. The actuator is arrested whenever it reaches the electromagnetic stop unless this occurs in synchronism with the de-energizing pulse. When the thermal switch has timed out the magnet is permanently de-energized and the facsimile transmission commences.

Abstract: 1,181,501. Coated surface. W. A. WOOD and D. GRAY. 6 Jan., 1967 [6 Jan., 1966], No. 686/66. Heading B2K. Coated surfaces are obtained by preparing the surface to remove any loosely adhering particles or layers therefrom, applying an uninterrupted prime coat comprising urethane modified drying oil or semi-drying oil alkyd or urethane oils which have an affinity to the prepared surface, in the absence of cellulose acetate butyrate, and applying over the prime coat when set or cured a protective coating which has an affinity to the prime coat material. A pigment may be added to the prime coat, the pigment being for example red lead, calcium plumbate, zinc chromate or zinc metal. The prime coat may be a modified urethane alkyd resin such as a urethane modified linseed oil alkyd. The base may be of ferrous or non-ferrous metals, pre-treated metals, brick, stone, asbestos, synthetic resin plastics, ceramics, cardboard, chip-board, wood, concrete or plaster. The pre-treatment may be a scraping, wire brushing or shot blasting. A decorative coat may be applied over the top coat. In examples the method is used for coating pipes and a gas holder.

Title: Television camera
IPC: H04N5/228
Filed: 1963-01-07
Abstract: 982, 967. Photo-electric waveform generators. FERNSEH G.m.b.H. Jan. 7, 1963 [Jan. 5, 1962], No. 689/63. Heading G1A. [Also in Division H4] To prevent "burn-in" effects on the target electrode of an image-orthicon pick-up tube the electrons emitted by the photo-cathode are subjected to a periodic deflection under the control of photo-electrically generated deflecting waveforms. Thus, as shown in Fig. 1, an eccentrically mounted rotary shutter 17 co-operating with perpendicularly inclined fixed radial slots 15, 16 periodically varies the amount of light from a source 10 which falls on respective photo-electric cells 8, 9 the outputs of which consisting of 90 degrees phase displaced alternating currents are supplied via amplifiers 6, 7 to auxiliary deflecting coils 4, 4<SP>1</SP> and 5, 5<SP>1</SP> surrounding the image section of the image-orthicon tube to produce a circular motion of the photo-electrons. Instead of the latter arrangement three fixed radial slots mutually displaced by 120 degrees and three sets of auxiliary deflecting coils may be employed. The amplifiers 6, 7 are preferably arranged to provide scanning currents which alternate in both positive and negative directions with respect to zero output so that the displacement of the electron image is symmetrical with respect to its undeflected position. The rate of the circular motion of the electron imate may be between one and ten revolutions per minute and the drive for the rotary shutter 17 is conveniently derived via a suitable mechanical drive 18 from the motor 20 which drives the usual "working-hours" counter 18.

Abstract: 534,184. Making engine mounting rings &c. BRAIME, Ltd., T. F. & J. H., and BRAIME, T. F. Jan. 12, 1940, No. 720. [Classes 83 (ii) and 83 (iv)] Uniting by fusion.-A built-up ring of circular, rectangular or other shape, such as an engine mounting ring for aircraft, is made by pressing or otherwise forming two or more sections, locating them on a complementary former, welding the sections at spaced points and then moving the former and ring relatively to each other to allow the completion of the welds.. The ring may be formed of two pressed U-sections 2, which are assembled on a former 12 having recesses 13 co-operating with projections 3 on the sections, which serve to lock the assembled ring against movement and also subsequently provide bosses for the passage of the engine securing bolts. The former is also provided with slots 14 through which the two sections of the ring may be tack welded internally. After tack welding internally and externally the former and ring are then moved apart and the welding completed. Solid or hollow strengthening bosses or bobbins, 7, 4, Figs. 5 and 4, with reduced ends may be placed between the sections at the parts 3 during assembly. They are subsequently welded at 27, 26. The edges of the sections may be chamfered or spaced slightly apart by the bobbins to provide a welding recess. Face plates 28 and collars 29 and brackets may also be welded in position on the ring while it is on the former. The former 12 may be mounted on the centre 15 of a jig table 16 and the ring sections assembled thereon and held together by bolts 17 passing through the bobbins. The ring and former may then be lifted off the jig table and mounted on a rotatable table 18 for the welding operation. Bolts 19 on the table pass through holes in the former and the ring is held by clamps 20 against facing blocks 21 on the table. Wedges 22 temporarily hold the sections evenly apart. After tack welding the former 12 is drawn towards the table 18 by bolts 19 to expose the whole of the inside joint for completion of the weld. The bobbins are then welded and the face plates &c. welded. The face plates 28 are welded through countersunk holes and also round the edge. Small boles 31 are provided to line up with centre markings on the solid bobbins to indicate the correct position.

Title: Dielectric recording medium and a method of making a record
Inventor: WILKINSON RICHARD L
IPC: B41M5/24
Filed: 1986-07-03
Abstract: A multi-layer information recording medium for storing large amounts of information in a prescribed pattern of microscopic pits, formed by focusing onto the medium a beam of radiation having a prescribed wavelength and having an intensity modulated by the information to be recorded. The record medium includes a substrate having a light-reflective surface on its upper side, a light-absorptive dielectric layer overlaying the substrate and having a thickness approximately equal to an odd integral multiple of one fourth the wavelength of the beam of radiation in the dielectric material, and a thin metallic layer overlaying the dielectric layer and having a light-reflective surface on its lower side. During recording of the information, a substantial proportion of the intensity-modulated beam of radiation is transmitted through the metallic layer to the dielectric layer where it is confined, due to multiple internal reflections by the light-reflective surfaces of the substrate and the metallic layer, until it is finally absorbed by the dielectric material. This causes an evaporation of the dielectric material whenever the intensity of the beam exceeds a predetermined threshold, such evaporation carrying away the overlaying portions of the metallic layer and creating the prescribed pattern of microscopic information-bearing pits.
