IPC: B31D1/02
Filed: 1958-11-25
Abstract: 865,165. Pressure sensitive labels. DICKINSON & CO. Ltd., John. Dec. 10, 1959 [Nov. 25, 1958], No. 37918/58. Class 73. Relates to the production of pressure-sensitive label strips comprising labels secured adhesively to a protective backing strip from which they are removed when required for use. A laminated web 10 comprising a strip 11 of label material superposed on a backing strip 12 is unwound from a reel 13, the two strips being separated by passing them over guide rolls 14, 15. The label strip 11 has its lower side coated with a non-drying pressure sensitive adhesive and is conveyed through a cutting station comprising a rotary cutter 16 and a rotary anvil roll 17. The cut-out labels 18 adhesively adhere to the anvil 17 while the label strip matrix 19, i.e. the waste portion of the label strip, is drawn over a guide roll 20 to a rewind reel 21. The labels 18 are transferred to a transfer roll 23 by means of a stripper blade 22 and suction apertures 24 in the roll 23 and are then fed together with the backing strip 12 between the roll 23 and a roll 25 whereby the labels 1'8 are adhesively secured to the strip 12. This is then severed into the required lengths or, as shown, wound on a reel 27. Modifications are described which eliminate the transfer roll 23 and avoid the labels sticking to the anvil roll. Means 36-39 (Fig. 3, not shown) may be provided for printing the labels.

Abstract: 1,249,625. Measuring borehole inclination electrically. SOIL MECHANICS Ltd. Feb. 24, 1969 [Nov.23, 1967], No.38772/67. Heading G1N. A borehole inclinometer to measure differential slippage of earth strata comprises a chain of inductive transducers, 10, which chain is centred in an initially vertical borehole 4, by springs 18, so that earth movement imposes a curvature on the chain. The transducer comprises a rigid rod, 6, connected by a rigid bar, 12, to a coaxial component 11, the disposition of which component is sensed by quadrilaterally disposed components 14 inductively coupled to that, 11. The components 14 are arranged in two pairs to sense displacement along each of two perpendicular axes normal to that of the borehole. A signal from the transducer is fed to terminal equipment 15 at the mouth of the borehole by means of wires 16 which signal is decoded to provide a reading of the angular displacement of the axis of a rod relative to that of an adjacent one. Such signals are summed to indicate the overall bore curvature and hence the extent of earth slippage. The component 11 is flexibly connected to the adjacent rod by a flexible bar, 13, or, Fig. 3, (not shown), by two rigid bars (13a) and a universal joint (17). The components 14 are supported on a tubular extension, 8, which is joined to that, 7, by a flexible bellows 9. Each transducer includes two ferrite pot cores.

Title: Mechanism for shifting the work in a zigzag sewing machine
IPC: D05B3/24
Filed: 1959-11-16
Abstract: 879,750. Sewing-machines. SINGER MANUFACTURING CO. Nov. 16, 1959 [Nov. 17, 1958], No. 38852/59. Class 112. Mechanism for moving the work in a zig-azg sewing-machine includes a work engaging foot 55 carried on a feed blade 50 arranged to undergo rectilinear and turning movement with respect to the sewing-machine, a rotary actuator receiving step-by-step turning movement from the machine, follower means 112 mounted on the feed blade and engaging the rotary actuator, the feed blade being mounted to pivot on and to slide transversely to a fulcrum pin 63 which has its axis parallel to that of the rotary actuator. The pin passes through a slot 60 in the blade, a slot 61 in the frame 40 and a hole in an angle bracket 64 which latter may be selectively positioned on the frame along the slot 61. The rotary actuator comprises a pinion 101 which engages the rack teeth of the follower 112 which is detachably mounted on the feed blade. The pinion is rotated in steps by a ratchet wheel 100 driven by a pawl 94 mounted on a carrier 93 oscillated about the axis of the actuator by a link 96 operated by a lever 27 driven from the needle bar of the sewing- machine. The leaf spring 104 which presses the ratchet wheel 100 on to the frame 40 has a finger 105 which forces the pawl 94 out of engagement with the teeth of the ratchet wheel for a portion of the travel of the pawl, so that variation in the stroke of the drive lever due to the attachment being used with different machines will not be critical, and shifting of the work will occur only when the needle is well out of the material being stitched. A manual ratcheting lever 87 is also pivoted about the axis of the actuator and has a pawl 91 engaging the ratchet wheel. The attachment is provided with an anti-flagging finger 140 mounted for vertical movement on a stud 147 secured to the frame, and lifted against the action of the spring 148 by the co-operation of a lip 145 with a cam surface 146 formed on the drive lever.

Filed: 1960-11-11
Abstract: 911,584. Automatic tension control. STANDARD TELEPHONES & CABLES Ltd. Nov. 11, 1960, No. 38878/60. Class 38 (4). In a magnetic tape recorder, the tensions in a tape 6 being fed from a supply reel 10 over a magnetic head 2 and capstan 9 to a take-up reel 11 are automatically controlled. The tensions in the tape, before and after the capstan, is detected by movable spring-loaded arms 17, 19 mounted coaxially with the reels 10, 11. Variation in tape tension causes the arms to move and by arm 17 switches 25 to 28 are actuated selectively. When the tension in the tape is between predetermined limits the reel rotates freely. An increase in tension causes the arm 17 to move anticlockwise until the switch 25 is actuated to energize a clutch, not shown, connecting a motor, not shown, to the reel so as to drive the reel in a direction tending to reduce the tension. A reduction in tension cause the arm 17 to move clockwise, a switch 26 being actuated to energize a brake, not shown, for the reel. The operation of the arm 19 and associated switches is the converse of that for the arm 17. The capstan 7 is driven through a clutch by a second motor and a capstan shaft carries a pulse generator, comprising a toothed rotor varying the flux through a fixed coil. Switches 27, 28 are actuated by the arm 17 when switches 25, 26 fail.

IPC: C03B19/10
Filed: 1964-10-06
Abstract: Spherical bodies of high compressive strength particularly for use as packing materials for chemical reaction towers, porous load-supporting beds, and proppants in oil and gas wells, are made by fusing glass or glassy material such as slag and then quenching in a liquid of a viscosity greater than that of water, e.g. aqueous solutions of waterglass, starch, soap, ethylene glycol, or oil. Glass is crushed, mixed with a carbonaceous material to separate the particles, heated in a crucible or on a travelling belt to cause incipient fusion of the particles and cause them to become spherical, and then dropped into the cooling liquid, preferably after falling through the air for a short distance; alternatively slag, to which may be added small amounts of silica, alumina or a boron compound, can be used, heating, preferably at about 200 DEG  C. above the melting point, being continued until the evolution of gas ceases, and quenching (if desired after granulating by allowing the molten material to fall first on to a rotating disc passing through a screen, or blowing from a bath) being effected by allowing the material to fall into a bath of solid materials or a liquid other than water.  Glass spheres must be quenched from not less than 650 DEG  C. and slag spheres from not less than 980 DEG  C.
