Title: Method of manufacture of bags from two or more thicknesses of paper or the like
IPC: B65D30/18
Filed: 1927-12-19
Abstract: 296,240. Klein, E. Dec. 19, 1927. Paper bags, making; paper bags.-In making bags formed, of two or more layers of paper, the inmost and outmost layers are formed from a single sheet a by folding it upon itself, the fold being formed at the upper or filling end of the paper tube to be formed and being cut at one side to form two flaps d', d<11> between which the opposite side e of the folded sheet is adhesively secured. The sheet is folded so that one edge a<2> extends beyond the other edge a<1>. Further single or double sheets n may be inserted between folds of the sheet a and positioned so that one edge projects between the flaps d<1>, d<11> and the lower edge between the edges a<1>, a<2>, the arrangement providing a stepped formation in each instance. The edge of the inserted sheet may be secured by a strip of adhesive paper to the fold c. In making the tubes, paper having a width equal to twice the length of the tube is drawn from a roll. folded approximately at its middle and severed into lengths to the circumference of the tube plus the width of the adhesive seam, the fold positions lengthwise of the bag being simultaneously stamped out. The sheets may be folded so that the longer piece a<2> is either inside or outside. In the former case, to form the bottom of the bag. two triangular folds are made with the inwardly directed edges a<11>, Fig. 7, overlapping, a rectangle y of paper is stuck over all the exposed edges. the triangular flaps k, l are turned in, and a second piece of paper is stuck over them and the piece y. When the edge a<1> is outermost, small triangular flaps m, Fig. 10, are made, a length of paper n is stuck on them and the long flaps are turned over about the lines C, D and E, F to overlap and be adhesively secured to each other. The upper end or mouth of the bag may be closed as shown in Fig. 14 to form a filling valve. One end of a paper strip q is tucked beneath one of the triangular folds and secured there by adhesive applied to the upper surface of the strip. The long flaps c are then folded on to the strip and adhesively secured thereto, the strip being folded over at s and secured to the upper sides of the flaps. Instead of folding over a single strip, two separate strips may be used.

Title: Apparatus for detecting dirt or foreign bodies in transparent bottles
Inventor: FORD GEOFFREY EWART
IPC: B08B9/32
Filed: 1963-09-02
Abstract: 1,098,174. Photo-electric bottle inspection. FORDS (FINSBURY) Ltd. Sept.2, 1964 [Sept. 2, 1963], No.34548/63. Heading G1A. Foreign bodies in transparent bottles are detected as the bottles supported upon a rotating pedestal and illuminated with diffused light pass in turn in front of a vertical stack of photo-cells which scan the side walls of the bottle through a vertical slit moving in concert with each bottle. Lenses may focus an image of the bottle wall on the photo-cells or the photo-cells may be so close to the slit as to obviate the lenses. A moving lens focuses, for a short interval, a stationary image of the bottom of the bottle on a fixed photocell as it passes beneath, a diffused light-source illuminating the bottle from below. In Fig. 1, which shows a plan view of the apparatus, bottles 30 are successively fed by the star wheel 2 on to pedestals 8 where they are clamped and rotate as they come within the field of view of the vertical stack of photo-cells 41, as determined by the adjustable opening 4, or a series of vertically arranged openings, 44. The moving slits 40 and moving stack of lenses 42 permit the photo-cells to view only a small portion of the bottle wall at any one time, a foreign body present then causes a signal from the photo-cells which passes via analyzing circuitry to a memory device to subsequently operate a reject mechanism. The individual photo-cells have differing sensitivity to reduce the effect of moulded in names and ridges and the analyzing circuitry distinguishes between foreign body signals and those from expected variations in glass thickness. The bottom of the bottle is inspected as it passes over a diffused light-source 47 and beneath a fixed photo-transistor (not shown) upon which is formed a stationary image of the bottom by a moving lens Fig. 3 (not shown). Signals from the photo-transistor and those from a mechanical gauge sensing the neck of the bottle are stored in the memory device.

Abstract: 619,199. Sawtooth generating circuits. PHILIPS LAMPS, Ltd. Nov. 26, 1946, No. 35078. Convention date, June 8, 1943. [Class 40 (vi)] In a sawtooth generator of the type in which a capacitor is charged or discharged through a constant current device, any residual non- linearity, due for example to the blunting of a control impulse applied to the constant current device by stray inductances and capacitances, is minimized by adding an appropriate voltage to that appearing across the capacitor. As shown, this is effected by connecting an adjustable resistor 7 in series with the capacitor 3 which discharges linearly through constant current pentode 5 whenever a control impulse is applied to the control grid of the pentode.
