Title: Improvements in and relating to the sealing of cartons
IPC: B65B7/18
Filed: 1940-02-06
Abstract: 538,609. Packeting. BEASLEY, H. H., and BEASLEY, FRENCH & CO., Ltd. Feb. 6, 1940, No. 2280. [Class 94 (i)] Relates to a method of and machine for sealing cartons in which a waxy or like coating or impregnant of a carton is softened by heat treatment to obtain tacky areas which are pressed together and then cooled to harden them. According to the invention, each carton is passed through, heating, pinching, and cooling stages by a number of intermittent movements in each stage, and during each stationary period a carton is automatically displaced from the heating stage into the cooling and pinching-stage simultaneously with the feeding of a new carton into the heating stage, each carton being continuously treated in each stage during a succession of stationary and moving periods. The machine comprises a conveyer 2, Fig. 2, which carries the open cartons to the machine, intermittently rotated tables 5, 6, 7, and a discharge conveyer 3. A carton is pushed off the conveyer 2 by a reciprocating pusher 14 on to the table 5 beneath a hood 13, Fig 5. The hoods 13 are reciprocated vertically by a cam 28, and when a hood descends, it folds in the upper end of a carton as shown in Fig. 6. Each hood is of inverted V-shape, and the movement of the carton 1 on to the table 5 beneath a hood folds a flap 1a, formed on one side of the carton, on to the other side of the carton mouth. When a hood descends, a horizontal plate 13d engages the flap 1a and folds it as the carton is pushed off the table 5, by a pusher 15, on to the table 6. A heating chamber 17 is supported above the table, and the chamber contains radial channelsection bars 18 each shaped to engage the closed upper portion of a carton. As a carton moves on to the table, the closed flap engages in a bar 18 which is heated by any suitable means, such as electric heaters 19, the temperature of the bars being regulated, if required, by a thermostat 20. The heat softens the wax at the closed flap, and when a carton is moved by a pusher 21 from the table 6 on to the table 7, the softened portion is engaged by radial pinching-devices 22, Fig. 2, The pinching operation cools and hardens the softened wax, and a cover 57 over the table 7 forms a chamber 58 which may be cooled by suitable means to assist the hardening. Finally another pusher 50 moves the sealed cartons on to the conveyer 3.

Abstract: 672,343. Magnetic switches. GRAVINER MANUFACTURING CO., Ltd., WILKINSON SWORD CO., Ltd., MATHISEN, A., HALL, H. W., and STRAIN, R. N. C. April 3, 1950. [Feb. 1, 1950] No. 2590/50. Class 38 (v). [Also in Groups XXVI, XXXV and XXXVIII] A temperature responsive device specially suitable for giving warning of excessive temperatures in the various fire-proof compartments of a jet engine plant on an aircraft (see Group XXVI), comprises a cap 2 of magnetic material, which on reaching its Curie point loses its magnetic properties thereby causing relative movement between itself and a permanent magnet and the consequent operation of contacts. In the form shown in Fig. 2, the element 2 normally attracts one pole of an L-shaped permanent magnet 10 mounted in a frame pivoted at 12 and holds it in the position shown against the repulsive action of a second' permanent magnet 16 till the Curie temperature is reached when contacts 13, 14 are closed. When the temperature drops the parts resume their original positions. The magnet 10 and frame are pivoted at their C. of G. so that vibration has no effect and a blade spring 17 presses on the pivot pin to take up any play. In a modification, the frame carries one magnet which attracts the cap 2 and another magnet which is repelled by a third magnet. In another modification, the frame is biased by a spring and by air blast from an air scoop, and carries one U-shaped magnet with a short leg. The magnetic elements may be made of ferro nickel with nickel varying from 34 per cent to 45 per cent if the desired temperature of the Curie point is between 250‹ C. and 450‹ C. The elements may also be blackened or coated with silica so that they respond more readily to change of temperature.

[Also in Division F4] A water heating system includes a closed boiling water tank fed by a supply conduit having a non-return or back-pressure valve; heating means having both a thermostat adjusted to a predetermined temperature below boiling point and a switch for optionally rendering the heating means operative to boil the water; a vapour withdrawal conduit connected above the normal water level and having a control valve; and a boiling water withdrawal conduit connected below the normal water level; whereby, if the water is boiled and the control valve closed the operated steam pressure forces water out of the boiling water withdrawal conduit. Boiling water tank 10 is fed from cold water supply 13 via warm water tank 11 and non-return valve 18, and includes a thermostatically controlled heating element 20, and two further heating elements 22 and 23 which are energizable by manual operation of a switch to boil the water. Hot water can be withdrawn from tank 10 via conduit 25, and boiling water via conduit 40 by closing valve 31 in the vapour withdrawal conduit 30 which leads to a heat exchanger consisting of coaxial tubes 32, 33 mounted in, and heating, the warm water tank 11, tube 33 being in communication with the atmosphere by way of the loose fitting cap 35. Steam may be withdrawn via conduit 45 by opening valves 31 and 44. The boiling water withdrawal conduit 40 projects into a longer bore tube 42, and extends therein below the level of an air inlet 43, to prevent syphoning. The operating lever 51 of valve 31 may be arranged automatically to switch off the additional heaters 22 and 23 when it is operated to close the valve in order to withdraw boiling water. A modification (Fig. 3, not shown) dispenses with the hot water withdrawal conduit 25, but has a mixing vessel connected in conduit 17 between the warm water tank and the valve 18, which in this case is of back-pressure type, whereby water drawn off through a hot water withdrawal conduit from the mixer consists of a mixture of water from tanks 10 and 11. Specifications 944,652 and 944,653 are referred to.

Abstract: 389,959. Electromagnetic relays. ERICSSON TELEPHONES, Ltd., 67, Kingsway, London, and NEWELL, G. R., Ericsson Telephone Works, Beeston, Notting- ham. Feb. 2, 1932, No. 3065. [Class 38 (v).] Indicators.-In a combined electromagnetic indicator and relay of the type used in telephone exchanges, the armature is maintained in the operated position upon de-energization of the magnet by a locking member which has no retarding effect upon the operation of the armature. Fig. 1 shows an indicator similar to that described in Specification 167,522, [Class 40 (i), Electric signalling systems &c.], wherein the armature and indicator flap assembly comprises a channelshaped member D which pivotally supports the armature A and indicator B interconnected by a stiff wire C. The armature is operated by a coil wound on a core and contained within an iron shell S, the armature being normally maintained in its retracted position by a helical spring contained within the end of the core and adapted to co-operate with disc DS on the armature. The armature assembly is fixed to the shell S which is supported on a front plate FP in such a manner that a protecting cover, Fig. 3, may be slipped through a hole in the front plate and over the end of the shell. The cover is provided with a label LB covered by a window W and arranged to form an O-shaped aperture for revealing the indicator flap B. The armature is adapted to be locked in the operated position by a pivoted two-armed lever LM the upper arm of which in the retracted position of the armature, rests against the armature. When the armature is attracted the lever LM turns about its pivot under the action of gravity into a position such that the ,upper arm is substantially at right angles to the armature and holds the latter looked. During this movement the lower arm moves freely in a slot T2 in a member N operable by a push button PB which when depressed restores the lever and allows the armature to move to its normal position. The lower arm of the lever may be insulated in order that restoration may be effected by the insertion of a plug in a jack. The armature operates contacts mounted in the front face of the coil, the insulated boss I being provided for that purpose. The inertia of the locking member produces a. time lag between the operation of the armature and locking thereof, thus preventing permanent operation in response to short pulses of exciting current.
