Title: Apparatus for automatically closing and sealing the flaps of cartons
IPC: B65B7/20
Filed: 1964-05-12
Abstract: 1,069,448. Centring cartons in carton-closing machines; endless and roller conveyers. INTERNATIONAL STAPLE & MACHINE CO. May 12, 1964 [May 28, 1963], No. 19693/64. Headings B8A and B8C. The conveyer in a cartonclosing machine automatically disposes cartons of different widths so that their longitudinal centre lines lie in the same position to facilitate subsequent folding and sealing. Adjusting for width of cartons.-The cartons are fed over rollers 2 (Fig. 4) by endless belts 74 held on frames which are moved inwardly by a pneumatic ram 81, and, to ensure that they are always equally spaced from the centre line of the machine, the frames are secured to opposite runs of chains 80 running over connected sprockets 77. An adjustment of the belts permits them to register the carton with a line displaced from the centre-line of the conveyer. Adjusting for height of cartons.-Folders for the top flaps of the cartons are carried by a carriage (5) (Fig. 1, not shown) moved vertically in response to operation of a feeler (72) gauging the height of each carton. The feeler (72) is pivoted at the end of a hinged link (35) which is engaged by tall cartons so that it moves against the bias of a pneumatic spring to operate a microswitch (106) which causes the carriage (5) to be raised. Smaller cartons pass under the arm (35) to operate a microswitch (102); this causes the carriage (5) to be lowered until the flap (72) engages the carton to operate a microswitch (103). Folding carton flaps.-The leading flap (la) (Fig. 1, not shown) of the carton is folded by the bottom edge of the arm (35) which is held by pneumatic spring (70). The trailing flap is folded down by a folder (57) swung by a pneumatic ram (62) about its pivot on an arm (36) turned, through a chain-and-sprocket mechanism, from a pneumatic ram (49). The side flaps are folded down, as the carton travels towards the stapling device, by inwardly inclined arms 34. Stapling or securing flaps.-Upper and lower stapling heads (95) (95a) (Fig. 1, not shown) are mounted on a manually adjustable linkage so that it can be disposed to apply a central line of staples, where the side flaps do not overlap, or a line of staples spaced from the centre line, where the side flaps overlap one another. The staples may be arranged parallel to or at rightangles to the longitudinal axis of the machine. The cartons may alternatively be secured by tapes or glue. Automatic control devices.-Each operation is initiated by a limit switch operated when the carton reaches the proper position.

Patent GB-753287-A (GB)
Title: Improved method of, and apparatus for, extracting a substance from particles
IPC: C11B1/10
Filed: 1954-07-06
Abstract: In a process for continuously extracting a substance from particles (e.g. oil from seed) by means of a solvent, the particles and solvent are fed respectively into an elongated, substantially horizontal, extraction vessel at different regions thereof and passed through in counter flow, a surplus of solvent being maintained constantly in the vessel either at the top or bottom thereof, depending on whether the particles are heavier or lighter than the solvent, and the surplus solvent being sucked out of the extraction vessel at the top or bottom at a plurality of spaced places between the regions <PICT:0753287/III/1> <PICT:0753287/III/2> at which the solvent and particles are fed in and being returned to the extraction vessel at a corresponding number of places at the bottom or top respectively, thus setting up a rotational movement of the contents of the vessel; also, vibrations are imparted in the longitudinal direction to the contents of the vessel.  As shown (Fig. 1), seed is continuously fed into a filtering chamber 2 at one end of a cylindrical extraction vessel 1.  Solvent flows in at the opposite end through a pipe 5 and the miscella is discharged through the filter chamber and pipe 7 into a tank (not shown).  The cylinder is completely filled with solvent and the level of the seed is kept below the top of the cylinder. Pumps 8 are arranged outside the extraction vessel so that the sucking side of each pump communicates with the cylinder 1 at its top through slots 9, and the compression side communicates with the bottom through slots 10.  The connecting pipes to the pumps are tangential to the cylinder 1 (see Fig. 2) and are arranged so that the compression pipe enters the cylinder at a point nearer the miscella discharge end than the solvent entrance end.  A helical rotational movement of the contents is thus set up, but the speed of the rotational component should be such that the particles can drop under the action of gravity before they are carried to the top of the cylinder.  When the particles are lighter than the solvent, the surplus is sucked off at the bottom and returned to the top of the cylinder, and the particles are then allowed to rise to the top before they can be carried down to the bottom by the rotational movement of the solvent.  A baffle 11 may be provided to limit the movement of the particles.  The treated seed is drawn out by a pump 12. Counter-current motion is thus set up.  Pump 12 draws off fresh solvent together with the treated seed, and the mixture is therefore discharged into a filter 13, the filtered solvent being returned to the extraction vessel 1.  The contents of the cylinder are also subjected to longitudinal vibrations by vibrating means 15 coupled to rigid rods 16 carrying metal discs 17.

Title: Improvements in continuous electromagnetic wave transmitting systems
IPC: H03B5/10
Filed: 1920-07-08
Abstract: 147,757. Latour, M. Aug. 16, 1915, [Convention date]. Void [Published under Sect. 91 of the Act]. Clueless signalling. -In systems for generuting high - frequency oscillations by thermionic apparatus, the amplitude of the oscillations is modulated at an audible frequency (1) by supplying the plate circuit from an alternator; or if a direct-currant supply is used the same result may be obtained (2) by introducing a low-frequency oscillation circuit in the supply circait, or (3) by connecting an auxiliary condenser (in series or not with an inductance) as a shunt between the grid and the filament, the frequency of the oscillating circuit thus formed being regulated relatively to that of the main circuit in such a manner as to produce beats. If an alternator is used in the supply circuit, oscillations are generated only during alternate half-cycles, but two generators may be connected to the two halves of a supply transformer E, E, Fig. 6, in such a way as to operate alternately, oscillations being generated during every half-cycle. By throwing a switch K, the connexions of one of the generators can be reversed, so that the two generators operate simultaneously instead of alternately, alternate half-cycles being barren. in this position of the switch K the modulation frequency is the same as that of the alternator; in the other it is double. The modulation frequency can be further varied by using known arrangements for changing the number of poles in the alternator. The alternator may be rendered self-exciting by means of a condenser, and may be of a type which does not involve the use of sliding contacts. Or the alternator may be replaced by a D.C. dynamo with large voltage-fluctuations, which may be accentuated by means of a shunt condenser. Three generators may be connected, as shown in Fig. 8, to a threephase alternator I. The thermionic generators, instead of being self-exciting, as in the arrangements shown in the figures, may have their gridfilament circuits connected to a small auxiliary generator, such as a self-exciting valve. The valve filaments may be heated by batteries, or by current from the main alternator, regulation being effected by a variable transformer, or the alternator may have a separate low-tension winding for supplying heating-current. The arrangements described are applicable for wireless telephony, speech being possible in spite of the modulation note if the latter has a frequency below 100 or above 2000. The microphone M may be connected as shown in Fig. 8.

Title: A method of and apparatus for pickling metal
IPC: B65G49/04
Filed: 1937-07-16
Abstract: 498,860. Conveyers. GREER, A. J. R. July 16, 1937, No. 19811. [Class 78 (i)] [Also in Group II] In a plant for conveying coils of strip metal through pickling and washing troughs, each coil wound on a coiler A rolls down a platform B and is arrested by a stop member 17 pivoted at 18. When the stop is rocked by a cylinder 23 its upper surface 31 becomes horizontal, permitting the coil to roll on to it. A mandrel 33 is then inserted through the coil and the stop is restored to the position shown, so lowering the mandrel until its ends rest on inclined rails 24. The mandrel, carrying the coil, rolls down these rails and is received in the forked ends 28 of transfer arms 27 pivoted at 25. The arms are then lowered causing the ends of the mandrel to enter between curved guides 58 which lead them on to rails 35 extending above the pickling trough 34. The ends of the mandrel are provided with sprocket wheels 61, Fig. 7, which are engaged by endless drive chains 37 which cause the mandrel to roll along the rails. The coil is thus carried along and rotated with its lower portion immersed in the pickling fluid, so agitating the fluid and exposing each part of the coil alternately to the fluid and the air. At the end of the trough the mandrel leaves the chains 37 and rolls down inclined ends of the rails 35 into hooks 68 of pivoted transfer arms 67, at the same time tripping a limit switch to start a motor which rotates the arms and causes them to lift the mandrel and coil from the trough and transfer it to a washing trough 64. The two hooks 68 are of unequal length so that as the coil is raised its axis is tilted to allow the acid to drain from between the layers. The means for traversing the coils through the washing trough 64 comprise supporting rails 73 and drive chains 74 for the mandrels, similar to those in the pickling tank, the coils however being wholly immersed in the water. The coils are subsequently passed by similar means through a second washing trough 95, to and from which they are transferred by arms 98 and 127 operated similarly to the arms 67. The arms 127 deposit the coil on a cradle 133, the mandrel resting on notched bracket plates 138 so that it may be removed. The cradle 133 is then rocked by a cylinder 137 and discharges the coil on to a curved platform 144 of an upending device which is subsequently turned to bring the roller platform 145 to a substantially horizontal position, so that one end of the coil rests on it, and the coil is discharged from it to a gravity conveyer.

Abstract: 748,869. Oscillating machines; converting; automatic voltage control systems. KELVIN & HUGHES, Ltd. Aug. 4,1953 [Aug. 7, 1952], No. 19913/52. Classes 35, 38 (2) and 38 (4). [Also in Groups XIX, XL (b) and XL (c)] An electromechanical oscillator device comprises, in the embodiment shown, a permanent magnet 18 fixed for oscillation on a torsional support 17 and having arms 30, 31 projecting radially from the oscillatory axis of the magnet to which arms a spring 33 applies a resilient restriction, a core 20 having input coils 25, 26 for maintaining the system in oscillation and an output coil 27 for deriving from the system an alternating current of frequency determined by that of the system, and means whereby an operator can adjust the spring so as to vary the natural periodicity of the system over a given range. In an arrangement for indicating the speed of an engine not shown, the output coil 27 controls the conduction of a valve 60, Fig. 4, which in turn controls that of a valve 66 in the anode circuit of which is a transformer 68 which drives a motor 67 forming the frequency standard side of a differential gearing, not shown, the other side of which is driven by the engine whose speed is to be indicated. The frequency of oscillation may be varied by altering the inclination of the spring 33, Fig. 2, with reference to the arms 30, 31 and this may be effected by-a knob 42 acting through gearing 36, 37, 40 and a carrier 34. In operation the knob 42 is adjusted to vary the frequency of oscillation and hence the speed of the motor 67 until the output of the differential is zero at which point the corresponding engine speed is indicated on a dial 57, Fig. 1, by a pointer 56 which is connected through gearing and cam mechanism 45 ... 52 and 54, 55 to the gear 36. To provide against internal and supply voltage changes varying the output volts and natural frequency an automatic gain or volume control is provided which comprises a non-linear volt-ampere bridge 64 connected to the rectified output of valve 66. The bridge gives a voltage of polarity and amplitude dependent upon the voltage output of transformer 68, which bridge voltage biases the output coil 27. In another embodiment, Figs. 5 and 6, not shown, the resilient restriction spring comprises two helical springs disposed one at each side of the permanent magnet arm and whose tension is adjustable by means of gearing. Specification 748,930 is referred to.
