Title: Improvements in or relating to conveyors for box-wrapping systems
IPC: B31B15/02
Filed: 1944-08-30
Abstract: 608,938. Box-making machines. STEVENS, A. H. (Stokes & Smith, Co.). Aug. 30, 1944, No. 16488. [Class 18] [Also in Group XXX] A conveyer for transporting coated wrappers and box blanks to the vicinity of the form block of a wrapping machine comprises at least two, and preferably three, endless belts arranged side-by-side of which one only extends to the transfer station from which the assemblies are fed to the form block structure. Mechanism TG, Fig. 1, of the kind described in Specification 600,724 applies adhesive and adhesively coated tabs T to the wrappers W and delivers them to the conveyer C which carries them to the assembly station AS. At this point an operator places box blanks B upon them which have been bent and delivered by mechanism BM of the kind described in Specification 608,936. The assemblies are then conveyed to a transfer station TS adjacent to the form block 2 of the wrapping machine WM. Since the conveyer C is composed of belts 43, 41, 42. of which only the central belt 41 extends to the proximity of an operator at station TS, this station can be arranged-at such a distance from the path of the block 2 that the operator can transfer an assembly from the conveyer to the wrapping machine without undue exertion. Each belt is perforated and may be of fabric, but preferably is of fabric impregnated with or covered by rubber. The working run of the belt passes over the perforated upper surface of a suction chamber 52, Fig. 5, which is provided with an angularly adjustable transverse valve 70 in order that the suction may be reduced at the delivery end. The other end 53 is pivoted at 51 to the main portion in order that it may be swung upwardly to permit cleaning of the adhesive applying roller. This movement occurs when the frame 56, Fig. 2, which carries the idler roller 55, driving rollers 18, 19 and the wrapper feed rolls 57, 58 is turned about its pivot 59 and the roller 55 engages the underside of the extension 53. The driving roller 18 is made of rubber or other elastic material and is tapered as shown in Fig. 6. Its spindle 77 is mounted in bearings 78 which are pressed downwards by springs 79, the tension of which can be adjusted by screws 80. The roller 19 may be tapered in a complementary manner. At the receiving end the edges of the lower run of each belt are engaged by grooved pulleys. The pulleys 44 for the central belt 41, Fig. 3, are in a plane which is higher than the plane containing the pulleys 45, 46 for the outer belts. At the delivery end the edges of the belt 41 are engaged by pulleys 47, Fig. 5. The return run of each outer belt is passed between pairs of guide pulleys 50 which are mounted in a plane below that of the plane containing the return run of the central belt.

Title: Polyisocyanate modified polyesters
Inventor: EDGAR OWEN BURCHELL
IPC: C08G18/42
Filed: 1953-06-19
Abstract: A rubber-like material is obtained by reacting an organic polyisocyanate with a copolyester formed from ethylene glycol, terephthalic acid and an aliphatic alpha-omega-dicarboxylic acid containing 4-10 carbon atoms, the molecular proportions of the acids being from 0.54 to 0.82 of terephthalic acid to 1 of the other acid. Preferably the copolyester has a molecular weight of 2000-10,000 and the amount of polyisocyanate used is such that there are 1.0-2.0 isocyanate groups present for each end group of the copolyester.  The reaction may be modified by the addition of water, glycols or diamines.  Specified polyisocyanates are tetramethylene-, hexamethylene-, p-phenylene-, m-phenylene-, diphenyl-4 : 41-, toluylene-, diphenylmethane-4 : 41-, diphenyl ether-4 : 41-, and naphthylenediisocyanates; and toluene-2 : 4 : 6-, triphenylmethane-4 : 41 : 411-, and diphenyl-2 : 4 : 41-triisocyanates.  In an example an ester obtained by heating adipic acid with ethylene glycol and an ester obtained by heating dimethyl terephthalate with ethylene glycol in presence of litharge were heated together while slowly reducing the pressure and removing ethylene glycol.  The resulting copolyester having a hydroxyl number of 23 and an acid number of 0.28 was heated with naphthylene-1 : 5-diisocyanate and then a fine spray of water directed on the surface of the melt. The melt thickened to a rubber and was thereafter heated in an oven, homogenized on a mill, baked, re-milled and moulded.

Abstract: 256,752. Elsworth, T. F., Wright, F. W., Harker, P., and Mann & Co., Ltd., G. July 2, 1925. Delivery apparatus.-The driving-mechanism for the delivery chains of a printing-machine is controlled by a timed cam so that the chains receive a cyclic movement of the character described in Specification 19673/11, the speed of the chains being equal to the uniform peripheral speed of the impression or take-off cylinder during the take-off portion of the cycle, and being slowed down for the remainder of the cycle. Fig. 1 shows a form of cam applicable to the epicyclic driving-mechanism described in Specification 210,481. The cam comprises five sections, the larger section B-C being an archimedean spiral for the rim at maximum speed, the section D-H giving the minimum speed for delivery, the sections C-D and E-A a return to average speed, and section A-B acceleration to the maximum speed. Fig 2 shows the application of two similar cams 6, 7 set 180‹ apart in an offset rotary printing-machine in which the impression cylinder 1 makes two revolutions per impression, the cams having the main portion an archimedean spiral to give the uniform maximum speed for take-off. The cams control rocking levers 8, 9 tinked to rack-bars 15, 16 engaging with pinions 19 loose on a shaft 20 ,and provided with projections 21, 22 carrying pawls 23, 24 engaging with shoulders or notches 25, 26 on a boss 27 fast on the shaft 20, so that one rackbar drives the shaft 20 on its forward stroke while the other rack-bar returns idle on its backward stroke. The chain wheel 29 is driven from the shaft 20 through gearing 28, 30, 31, 32. In another arrangement the timed cam is used to reciprocate a sliding helical pinion forming part of the driving-mechanism.

Patent GB-241282-A (GB)
Title: Improvements in or relating to loose leaf binders
IPC: B42F13/12
Filed: 1924-07-17
Abstract: 241,282. Moore, C. H. July 17, 1924. Post files; covers; locks.-In a loose-leaf binder of the type having a rigid back, and vertical posts, on which the perforated leaves are filed, the posts are movable out of engagement with all the leaves without movement of the covers or back of the binder. The binder back comprises a box structure having a base plate A, end walls A' constituting guides for the leaves, and side walls A<2>, one of the walls A<2> having a cover c in which slides a locking-plate D while the other is provided with holes F in which slide the filing posts G mounted on a connecting bar F. The posts are semi-circular in form except for the ends G<2> which are rounded to engage with perforations in the locking-plate D and in a plate J which prevents total withdrawal of the posts. Automatic disengagement of the posts from the leaves on release of the locking slide D is obtained by means of the pressure of a spring F against the outside of the box. The covers K are hinged to the sides A<2> and are covered on the inside with sheets of fabric K<1>, the ends of which protrude into the box. One Provisional Specification states that filing posts engaging slots in the leaves may be provided instead of the guide members A<1>, the posts, which may be curved, being fixed at their top and bottom ends to the back of the binder, or having their top ends releasably locked to the binder by a sliding bar.

Title: Feed device for headed nails
IPC: B27F7/38
Filed: 1974-04-19
Abstract: 1441069 Discharging hoppers MAINETTI SpA 19 April 1974 [15 June 1973] 17197/74 Heading B8S A device for feeding headed nails to a power machine (not shown) comprises a box 3 which is open at its top and at one side and is movably mounted in a guide 2 on a frame 1, the nails being arranged horizontally in superimposed layers in the box 3 with their heads not necessarily ordered, the nails in the uppermost layer in the box 3 being removed individually by means of a pendulum 5 provided at its lower end with a magnet 5<SP>1</SP> which during each oscillation removes a nail from the box 3, the nail then striking against a fixed cross member 6 which causes the nail to fall into a hopper 7 and to slide along the hopper floor until it falls into an underlying channel 8 provided at its base with a slot of sawtooth shape along which the nail moves to the power machine, the channel 8 being vibrated by an electromagnet 9. Oscillatory motion of the pendulum 5 is caused by an electric motor 11 which rotates an eccentric disc 10 which engages a roller 12 mounted on a plate 14 rigid with the pendulum 5 to cause motion of the pendulum 5 in one direction, the return movement of the pendulum being effected by a spring 16, and the pendulum 5 is also translatable in a direction transverse to its plane of oscillation, such that for each complete oscillation it translates through a small distance corresponding to the diameter of one nail, the said translatory movement of the pendulum 5 resulting from the fact that the pendulum is mounted by means of a bearing on a block 17 fixed on a threaded shaft 18 which is rotated by the motor 11. When the pendulum reaches one end of its translatory stroke (i.e. when it has completely removed all the nails from the uppermost layer of the box) a screw 22 on a box 21 which moves with the pendulum 5 during its translatory moves actuates either of two pneumatic limit valves 24 (25), Fig. 1 (not shown), this causing reversal of the direction of rotation of the motor 11 and simultaneously causes the floor of the box 3 to be raised by a small amount by means of a pneumatic ram 4 to bring a fresh layer of nails to the level of the upper surface of the guide 2.
