Abstract: 1285196 Detecting flaws in transparent particles COMPAGNIE DE SAINT-GOBAIN 9 Oct 1969 [9 Oct 1968] 49617/69 Heading G1A A method or apparatus for the detection of flaws in transparent articles, e.g. bottles, comprises directing a modulated light beam on to a surface of the article, collecting the light from the article, converting the light received into a representative electrical signal and selectively amplifying the electric signal to detect variations in the intensities of the light received produced by the presence of flaws. In an apparatus for carrying out the above, light from an iodine lamp 1 is reflected by mirrors 2, 2a, and focused by lenses 3, 3a, as shown, to form two images of the lamp filament in the plane of the disc 4. The disc 4 has two concentric rings of apertures so when its rotated by motor 5 objective lenses 6, 6a receive two modulated light beams. Each beam enters a fibre optic distributor 8 or 8a through apertures 7 or 7a Fig. 2 (not shown) where it is distributed to four fibre optics cables which terminate in emitting heads 9. The emitter heads 9 include an optical system 12 to focus a pencil of light on to the bottle 10. Light is received from the glass by a receiving head 13 comprising an optical system 14 and a photo-electric cell 15. The cell is connected to an amplifier (not shown) having a narrow acceptance band and tuned to the frequency of modulation of the emitted light pencil.

Patent GB-518228-A (GB)
Abstract: 518,228. Automatically controlling combustion in stoves. THORNTON, A. A. (Reich- Oefen Ges.). Aug. 16, 1938, No. 24124. [Class 126] In a solid fuel or other stove in which combustion is regulated by a heat-sensitive element mounted in a chamber 4 arranged in the path of the flue gases in the flue outlet 5, the chamber is closed to the flue gases but open to the room atmosphere, so that the operation of element 1 depends both on the flue-gas temperature and. on the room temperature. In the forms shown, the heat sensitive element is a bimetallic strip, but it may alternatively be an expansion rod, a container filled with liquid or gas, or a thermocouple. In Fig. 2, the .element 1 operates either an air-inlet flap 6 or a spoildraught flap 23, when it comes in. contact 'with the arms 7, 27, but the spoil-draught flap may be omitted. When the fire is being lit, the flap 7'is held wide open by a cam operated from the front of the stove. The flue-gas temperature range in which the flap or flaps are operated is varied by adjusting the flow of air through the chamber 4 by the hit-or-miss, valve 13. In Fig. 4, this variation is obtained by hinging the flap 6 at 32 to a movable member 27 fixed to a rod 30 slidable in openings on a frame 24. By rotating a spindle at one side of the stove, an arm 37 engaging a forked member 36 fixed on the rod 30 causes the member 27 to move towards or away from element 1, so varying the position at which the arm 35 on the flap 6 makes contact with the element 1. In another form, the chamber 4 is pivoted near its. openend to the wall of the flue. In another form. the Chamber 4 is open at both ends to the room atmosphere and is mounted horizontally in a vertical part of the flue. The heat-sensitive element is adjustable horizontally by rotating a cylindrical sleeve provided with a helical slot 'in which engages a pin on a non-rotatable member attached to the heat-sensitive element.

Abstract: 1,242,003. Electric selective signals. MINNESOTA MINING & MFG. CO. 1 Nov., 1968 [3 Nov., 1967], No. 51997/68. Heading G4H. [Also in Division H1] An electron beam lens system, e.g. for an electron beam recorder, which comprises an electron gun 22, a first electron lens 80, an apertured mask 60 for passing the central portion of the electron beam and a second electron lens 66 for focusing the passed central portion of the electron beam, for example on to an electron sensitive medium 16, has a programming circuit for selectively and simultaneously controlling the electron gun and the electron lenses to increase or decrease the current of the generated beam, focus the generated beam to respectively increase or decrease the current density thereof, and focus the passed central portion of the electron beam to the desired respective larger or small cross-sectional area at the surface while maintaining the predetermined current density of the beam at the surface. The arrangement may be used to generate on the electron sensitive recording medium characters of two different sizes in response to the digital output from a magnetic tape or a computer 100. For generating the smaller character, e.g. with a spot size of 15Á, electron lens 80 is not energized; however, for the larger character, e.g. with a spot size of 30Á, electron lens 80 is energized to focus the beam 58 more finely on to aperture 62 in mask 60, the electron beam current from the electron gun is increased (e.g. doubled) and the focusing of electron lens 66 may be altered. A magnetic deflection coil 72 addresses the electron beam on to a predetermined area of medium 16 and deflection plates 70 selectively deflects the beam in small discrete strokes to image a character on to this area. As shown, the supply to all these components is controlled by a "controller and memory" 104 which in turn is responsive othe magnetic tape or computer output. Fig. 4 shows a filament-grid assembly 30 which can be plugged as a unit into the electron gun. The insulating support 142, filament 34 and conductors 36 form an integral unit which can be adjustably located, e.g. by screws 150, in the grid hollowed-out area 146.

In a two-bed warp machine for knitting tights or the like certain guide bars are shogged over adjacent needles of one bed during formation of the body portion and over needles on the opposite beds during formation of the leg portions. The control of these bars is shifted from one to the other of two sets of pattern chains in an auxiliary pattern mechanism. Guide bars 1, 2 and 11, 12 which supply yarn to front and rear needle beds respectively, and bars 3, 9 and 4, 10 which supply single ends of yarn to both beds at the ends of the blanks are controlled by main pattern mechanism A. The remaining bars 5-8 are controlled by auxiliary mechanism B which includes two sets of chains 51, 51a. The bars are moved by slides 42 mounted in a box 43, movable by a fluid cylinder and piston 56, 57. When a counter 65 has registered a predetermined number of courses, set by an operator (on scales 71, 72, Fig. 3 not shown), the box is shifted so that following rollers 50 follow the other set of chains. While 'body fabric is knit guide supply yarn to the front and rear needle bars 5, 6 and 7, 8 each carrying one control beds respectively. To knit two legs integral with the body, when the box is shifted, bars 5, 7 and 6, 8 supply yarn to opposite needles on the two beds to join the inside of the legs. Several strings of blanks, joined alternately waist to waist and toe to toe, are knit across the machine. The main and auxiliary pattern mechanisms, which may each include two sets of chains, may be at the same end of the machine. In a modification (Figs. 8-10 not shown) the bars are controlled by levers (94) pivoted on an axle (100) in a movable frame (104, 112- 115). The upper ends of the levers carry guides (97) which slide in a grooved upper frame member (98). The bank of levers is movable to follow either of two sets of chains (91, 91a).

Abstract: 1433157 Accelerometer SYSTRONDONNER CORP 14 Nov 1973 [29 Nov 1972] 52821/73 Heading G1A An accelerometer including a closed loop servosystem, is provided with a damping circuit for said system, the arrangement being such that on application of electrical power, damping is removed and dither induced into the system so as to overcome the effects of friction in the mechanical bearing assembly of the accelerometer. A timing circuit is used to gradually restore damping to its full value.  The dither circuit may be applied to an accelerometer of the type using a pichoff coil sensing movement of the accelerometer member, Fig. 1 (not shown), but is described with reference to one using a photo-electric arrangement. The accelerometer member is a torque coil 47 supported in bearings 49, a magnet 51 being mounted within the coil, and a return path for the field being provided by cylinder 52. The coil shaft also carries a flag 56, which in the absence of acceleration blocks light from light emitting diodes equally from reaching phototransistors PT1, PT2. On acceleration occurring, unbalance occurs and a signal is fed on line 58 via the servo loop including operational amplifier 61 to effect a restoring torque on the coil 47 via load network 76. A phase lead damping circuit 89 is provided by a further feedback loop comprising resistor 82 and capacitor 81 to the amplifier input 59. However, when the dither circuit is actuated this circuit is shunted out and suitability results, causing torque coil 47 to vibrate in its bearings. The dither circuit comprises a feedback loop including Cds photoresistor 72 and capacitor 81. On switching on power (switch 79), light emitting diode 85 is switched on to full intensity, causing photoresistor 72 to drop in resistance, resulting in  cancellation of the phase-lead, addition of phase lag and instability. The light emitting diode intensity is gradually reduced to increase damping asymptotically to its full value, under control of timing circuit 106. Voltage regulation by Zener diodes for the photo-transistors and current regulation for the light emitting diodes are provided.
