Title: Improvements in or relating to the examination of transparent sheet material
Inventor: WINCH GORDON THOMAS
IPC: G01N21/896
Filed: 1959-06-26
Abstract: 898,828. Drilling. GENERAL ELECTRIC CO. Ltd. May 16, 1960 [June 26, 1959], No. 22011/59. Class 83 (3). [Also in Groups XIX, XXIII and XL (b)] A method of detecting and locating internal flaws in transparent sheet material 2 comprises directing light from a source 5 on to an edge of the material and so causing any internal flaws F to be illuminated by internally reflected light and their positions to be marked by the presence of relatively bright areas on the surface of the material. A continuous glass sheet 2 is fed over rollers 1 and passes between a pair of tubular incandescent lamps 5 each arranged to focus an image of its filament on the edge of the sheet 2. If there is an internal flaw in the glass as at F a relatively bright spot formed by internally reflected light will appear on the surface of the sheet as the flaw passes between the lamps 5. The bright spot is detected by a photo-sensitive device 10 which is one of a number arranged to cover the width of the sheet. The output signal is passed to an amplifier and a delay device and can be used to operate a drill to drill out the flaw. If desired a warning can be given when a flaw has been detected and a counter may register the total number of flaws. The apparatus may also be used for examining single sheets of glass which are then directed into one or other of two reception channels depending upon the presence or absence of flaws. In addition to the edge illumination a light projector may be located on one side of the sheet and arranged to project light through the sheet from one face to the other. This will indicate surface faults if used with a photo-sensitive device as described above. In this case the two types of fault may be indicated differently. In a modification the array of photo-sensitive devices is replaced by a rotatable drum mounted above the conveyer with its axis extending in the direction of movement thereof. The drum carries on its periphery a system of mirrors so that as it rotates a single photo-sensitive device scans the whole width of the sheet of glass.

Title: Improvements in or relating to brushes
IPC: A46B3/12
Filed: 1947-08-08
Abstract: 657,024. Brush manufacture; twisted stem brushes. OSBORN MANUFACTURING CO. Aug. 8, 1947, No. 22094. Convention date, Nov. 22, 1943. [Class 19] A method of manufacturing brushes, especially twisted stem brushes, comprises the steps of placing a layer of brush material between flat opposed faces of a pair of parallel elongated retaining members, subjecting the portions of the members in contact with said layer to heavy external pressure so as to compress the layer laterally and compact the same and then securing said retaining members together while still maintaining such pressure, thereby to hold such layer tightly therebetween. The retaining members are preferably secured together by twisting the portions lying beyond the layer to form a brush as shown in Fig. 3. The twisting may be continued along the brush as shown in Fig. 1, the wires 2 being of half round section with their flat faces opposed. In the brush shown in Fig. 5 the brush has the construction as shown in Fig. 3 except that the bristles are trimmed to the form shown and this form of brush may be mounted in a holder 9 (Fig. 6) having a bore 10 to receive the twisted stem, the end 11 being tapered and transversly slotted to allow projection of the bristles. The brush shown in Fig. 3 may be provided with a similar holder with its forward end cylindrical instead of tapered. Another form of holder (Fig. 7) comprises a hollow cylindrical body 20 open at one end and provided at the other with a central stud 21 for securing it for rotation. The body of the holder is provided with a plurality of bores 22, each of which receives a brush such as that shown in Fig. 3 and radial slots 23 intersecting the bores 22 are provided to accommodate the brush layers with their outer ends projecting, the brush being adapted to operate on a work piece such as a boss W. Fig. 10 illustrates a method for making a brush of the type shown in Fig. 3. The layer 6 of brush material is inserted between the doubled portions of the wire 5 and the projecting wires passed through an aperture in a fixed abutment 13. Such wires are then pulled so as to press the brush layer against abutment 13. The wires 5 are then pressed between the movable jaws 14 and the wires lying beyond the abutment are gripped between rotary jaws 15 and tightly twisted together. Instead of a doubled wire two separate opposed members may be twisted together to form the stem the twisting being continued beyond the interposed brush material at both ends. The brushes may be made from continuous strands of brush material by applying thereto at spaced intervals pairs of the elongated retaining members, twisting the portions which lie beyond the layer while subjecting the layer to pressure between the members and finally severing the layer between each successive pair of said members.

Abstract: 763,030. Stencilling-apparatus. VEB. TEXTTILMASCHINENBAU ZITTAU. July 29, 1954, No. 22210/54. Class 100(2) In a stencil printing machine for textiles of the kind having a movable printing base to which the material is secured, and a number of printing stations, the base moving intermittently through pattern repeat lengths, and the stencils printing .by means of squeegees, an endless band running beside the base carries adjustable pattern repeat stops, which set the stencil carriages in correct position and also cause stopping of the base for printing. The base, 4, Figs. 1 and 2, running on rollers 5, 6, is provided with adhesive by mechanism 7 and cleaned by mechanism 13. The material 1 is adhered to the base and carried thereby over tables 8 and under stencils 9, intermediate drying apparatus 10, 11 and final drying apparatus 12, being then separated therefrom and wound on to rollers 14, 15. The roller 5 is in slotted bearings to allow for extension of the base 4. Beside the base 4 runs a non- extensible endless band 18, e.g. of steel strip adjustably joined at 24. The band 18 is driven by and in synchronism with the base 4, being secured thereto by stops 20, Figs. 2 and 5. The stops 20 grip the base 4 by jaws 21 adjustable according to the thickness of the base and movable into release position by a snout 87 running in guides near the pulleys 22, 23 so that the base 4 and element 18 are connected together only along the printing and reverse runs, but not near the pulleys 22, 23. Further stops 19 are provided, any of which can be pivoted to an inoperative position. A motor 16 drives a shaft 17 and the roller 6 and base 4. The shaft 17, Figs. 1 and 3, drives, at each printing station, through a magnetic coupling 42 eccentrics 35 and a switch 45. As the base moves, a snout 49 on a holder 19 operates a switch 50 to close the coupling 42, whereupon the stencil carriages 9 are lowered to the position 48. The stop 19 then abuts a stop 52 and moves the carriage 9 against a spring 46 to correct position, whereupon the stencil is further lowered to printing position and the switch 45 opens a coupling 27 to stop the base, the eccentrics automatically stopping after one revolution. The stencil mechanism includes a double squeegee 53, Fig. 4 which is rocked by means of a sliding bolt 56 connected to an element 59 driven by a reversible motor 60. The movement of the bold first rocks the squeegee and then moves the squeegee mechanism for printing, limit switches 61, 62 causing stroke reveirsal. A counter 63 stops' the motor after a desired number of strokes. On raising the stencil, the squeegee is raised first, since the latter is connected rigidly to a shaft 72 from which the carriage is supported by slotted bearings. The eccentrics 35 are arranged to raise one edge of the stencil first.
