Title: Improvements in glass cutting machines
IPC: C03B33/12
Filed: 1928-03-12
Abstract: 290,241. Price, W. C., and Price, W. H. G. May 11, 1927, [Convention date]. Cutting glass.-A machine for cutting glass sheets, and particularly for producing rectangular sections or glass tiles, comprises sets of cutters adapted to be reciprocated across a sheet of glass placed on the bed of the machine, and means for preventing the cutters from chipping the edges of the glass. The machine bed, shown in plan in Fig. 1, has two sets of slideways 9 disposed at an angle to one another, usually 90‹. The sheet of glass, 10, rests on adjustable supports 11 clamped to the bed, and stops 13 are provided to act as abutments for the sheet. The cutters are' carried by blocks 17, Figs. 1 and 4, clamped to a bar 15 which is pivoted, in a pair of slide blocks 14 that can be reciprocated along the slideways 9. The cutters 19 are mounted on holders 20 which are flexibly connected by springy steel strips 21 to the cutter blocks 17, and vibration is prevented by damping-levers 23. Each of the cutter bars 15 has secured to one end a lever arm 31, Fig. 7, which has a cam face 39 formed on its free end. A spring-operated trip lever 32 is pivoted to the arm 31 and has a hook 33 adapted to engage a projection 34 on the block 14. A blade, spring 40, secured to the cutter-bar 15, forces the cutters downwards into contact with the glass when the hook 33 is free from the projection 34. The cutters are raised during part of their movement by means of ramps 35, 36, Figs. 1 and 7, disposed in the slideways 9, which engage the cam face on the lever arm 31. A third ramp, 37, engages] the trip lever 32. In use, the operator moves the slide blocks 14 across the sheet 10 from the position shown in Fig. 1, and during this stroke the cutters are held out of contact with the glass, the ramp 35 having raised them, and they are kept in the raised position by the engagement of the trip lever 32 with the projection 34. On the return stroke, the ramp 37 engages the trip 32 and allows the spring 40 to press the cutters down into contact with the glass. The position of the ramps 36 and 37 is so arranged that the cutters are moved downwards gradually, but not until they have passed over the edge of the sheet, thus preventing them from chipping the edge.

Title: Moccasin manufacture
IPC: A43B3/14
Filed: 1965-02-24
Abstract: The upper blank of the moccasin is placed on a form and the edge portion which is to be joined to the plug portion is shortened along its entire length to match the shape and length of the edge of the plug, then the plug is permanently joined to the upper.  As described the upper blank is shortened by means of a draw string attached to the blank, e.g. by edge stitching, or by a lock stitch in which the draw string constitutes the bobbin thread. Alternatively the needle thread may act as the draw string and the bobbin provide guide thread loops.  The draw string is held in tightened condition by a clip, staples, studs, knots, or a plastic cement.  The blank may be of leather and may be mulled before being placed on the form and then set by drying.  The skived edges of the blank and plug are then joined together by cement with or without stitching.  The shoe is then mulled, force lasted, and force dried.  The draw string may be removed, or left as a decorative seam.  The machine for producing the lock stitch to guide the draw string may have a dull blade attached to the needle bar to form a series of regularly spaced indentations in the upper to facilitate shortening when the draw string is pulled.

Title: Improved printing process
Inventor: HEROLD EDWARD WILLIAM
IPC: B23K26/08
Filed: 1967-02-20
Abstract: 1,204,542. Farsimile systems. R.C.A. CORPORATION. 20 Feb., 1968 [20 Feb., 1967], No. 8007/67. Heading H4F. To produce a halftone image of a continuous tone pattern halftone dots of constant size are generated, but the spacing between the dots is varied so that the number of halftone dots per unit area portrays the continuous tones in the original pattern, and an additional random variation of the spacings between the halftone dots is superimposed thereon. As shown, Fig. 1, a flying spot scanner 50 scans a transparency 12 (negative of an original pattern) and a phototube 72 transduces the light signal transmitted through the transparency into a varying D.C. signal. Photo-tube 72 thus generates a relatively high signal when the tone scanned in transparency 12 has a low density, i.e. light. If the pattern to be scanned is an opaque photograph then the light reflected therefrom is utilized to obtain the image signals. The image signals are amplified 74, passed through a lowpass filter 82 which eliminates original highfrequency pattern components, limited, 84, and fed to a variable frequency oscillator 86 which produces signals having frequencies that are directly proportional to the amplitudes of the image signals. A cross-over detector 90 and a pulse shaper 92 convert each cross-over or zero amplitude point into a constant pulse, and the frequency of the pulse output depends on the frequency of the signal derived from oscillator 86. The pulse output is applied to a cathode-ray display tube 93 and each pulse is arranged to unblank the electron beam to produce light spots or halftone dots 104 which are focused on to a photographic film 97 which is then processed to form a printing plate, e.g. a gravure, letterpress or offset printing plate (Figs. 2a, 2c and 2d, not shown). A noise generator 112 is connected in the system to introduce a random variation in the spacing of the halftone dots that is superimposed on, and is directly proportional to, the average spacing of the half-tone dots in a region of the half-tone image. In a second embodiment, Fig. 5, a laser 120 is substituted for CRT 93 and the laser beam 124 is broken into pulses 126 by means of an electrooptic shutter 128 controlled by the F.M. image signal pulses from oscillator 86, and these laser beam pulses are deflected and focused, 136, on to a printing plate 122 and form identical sized cavities 127 thereon. The laser may alternatively be Q switched to provide pulses 126. Instead of forming cavities in plate 122 a photoresist covering of the plate may be hardened by the laser pulses. Plates for three or four colour printing may be produced.
