Title: Improvements in or relating to apparatus for setting-up cartons
Inventor: MOSSE RICHARD WOLFGANG EMIL
IPC: B31B3/46
Filed: 1959-01-26
Abstract: 874,665. Making cartons. METAL BOX CO. Ltd. Nov. 25, 1959 [Jan. 26, 1959], No. 2817/59. Class 18. A carton, of the form shown in Fig. 10, is made of cardboard with a coating of lowviscosity paraffin wax on both sides and has a thermo-plastic adhesive beneath the wax on one side where the carton is to be adhesively secured when in its erected form. The thermoplastic adhesive may be a polyvinyl acetate resin incorporating plasticisers. Heating means is provided to pre-heat each blank before it is presented to a die-and-plunger type erecting machine to reduce the time that the blank is in the die. In one form, Fig. 1, the blanks are held in a magazine 11 and transferred by a device 13 having suction pads 14 to a die and plunger 16, 15. The transfer mechanism is operated by the linkage shown from the driving shaft 27. A heater 31, Fig. 7, heats a blank resting on a ledge 12 and is moved away to the position shown dotted immediately before the transfer device operates by a cam 41 acting on a linkage 38, 37, 35. When an electric motor driving the shaft 27 stops, an electro-magnet 42 is energised and through a rod 47 connected to the member 38 moves the heater away from the magazine. Alternatively, the blanks may be pushed away from the heater. Radiant heater devices are also provided on the transfer device to continue the heating. A third heating device is incorporated in the die itself. Pressure is applied to the adhesive coated portions to secure them by members moved inwardly of the die by a linkage 52, 54, 55, 56, 58 and actuated by a cam 51. The cartons are removed by a suction device 60 into a shoot 61 for passing to a filling and closing machine ; in a second embodiment, Fig. 11, a pusher 75 on a conveyer belt 76 removes the cartons from the suction device. In the second embodiment, Fig. 11, the blanks are held in two magazines 11 on opposite sides of the die-andplunger, and the heating is effected by means on the transfer devices only. One device heats the next blank while the other device is carrying a blank to the die. When the machine is stopped relative movement occurs between the heaters and the magazine or the transfer devices are arrested at a position away from the magazines. Elements 66 locate the blanks above the die and are moved by cams 67 to act alternately as presser members.

Filed: 1972-01-21
Abstract: 1412122 Retractive switches ARROW-HART (EUROPE) Ltd 4 Jan 1973 [21 Jan 1972] 2960/72 Heading H1N A switch for incorporation in the handle 1 of a lawn mower, for example, comprises a tubular elongate housing portion 3a, 3c, a fixed contact and a co-operating movable contact, an actuating member 21 with its pivotal axis substantially at right angles to the longitudinal axis of said housing portion and finger-operable to close the contacts, a locking means 31 in the housing portion at a region remote from the actuating member 21 and manually slidable lengthwise of the housing portion between a first position, which prevents member 21 from closing the contacts, and a second position, which permits relative movement of member 21 to effect closure of the contacts, and means 35 urging the locking means 31 towards said first position. As shown, the locking means 31 comprises an insulating plate having a dependant finger 36, which abuts actuator 21 to prevent operation thereof. If the plate 31 is moved against the action of spring 35 by means of a thumb button 32, the finger 36 can enter a bore 27 and actuator 21 may then be pivoted against the action of its spring 30. An insulating plate 6 carries two strips 11 with fixed contacts (17, Fig. 5, not shown), and two spring blades 39 having contacts (18) for co-operation with the fixed contacts (17) to form a double-pole switch. As shown, blades 39 are biased towards the fixed contacts and lateral projections 25 on actuator 21 normally hold the contacts open due to the spring 30 being effectively stronger than blades 39. In the embodiment of Figs. 1 and 2 (not shown) the blades (19) carrying the moving contacts (18) are biased away from the fixed contacts and the projections 25 positively close the contacts when actuator 21 is pivoted.

Title: Improvements in and relating to an electronic switching network
IPC: H04Q3/52
Filed: 1964-01-24
Abstract: 1,003,774. Automatic exchange systems; transistor gating circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 24, 1964 [Jan. 28, 1963], No. 3170/64. Headings H3T and H4K. In order to reduce interference in a switching network composed of a number of stages of matrices of bi-stable electronic cross-points each marking voltage employed to establish a conducting channel through the cross-points is disconnected from the cross-points it controls as soon as one of the cross-points becomes conducting. As shown in Fig. 6 a PNPN transistor 1 comprising a cross-point in one switching stage can be switched to its conducting state to provide a speech path by way of a link 5 to a further stage where the path may be continued over a PNPN transistor such as 2. If the cross-point 1 is required in a speech path its emitter is connected to 24 volts and its base is switched from 30 volts, connected over normally conductive transistor 21, to 16 volts by a marking pulse on terminal 16 which cuts off transistor 21. As cross-point 1 switches to its conductive state the appearance of 24 volts on the link 5 triggers a one-pulse generator 27 causing the collector of transistor 21 to rise to 30 volts and thereby discontinue the effect of the marking pulse on terminal 16. Instead of being triggered by the voltage on the link 5 connected to an outlet of the switching stage the one-pulse generator may be triggered by the current pulse which occurs in the inlet to the stage, this arrangement being particularly suited to the last stage of the switching network. The network is of the kind described in Specification 849,873. A check that the network operates correctly when a path is set up across it may be carried out as described in Specification 1,003,773.

Title: Improvements in constant current systems
IPC: G05F3/04
Filed: 1939-02-01
Abstract: 524,627. Protective arrangements. STANDARD TELEPHONES & CABLES, Ltd., and JACOBSEN, B. B. Feb. 1, 1939, No. 3337. [Class 38 (iv)] In constant current power supply arrangements in which the loads are connected in series and operate at constant current, a resistance having a negative resistance-voltage coefficient is connected, in series with a constant resistance, in parallel with each individual load. Fig. 4 shows two main loads 1, 2 each consisting of three parallel loads L1, M1. N1 and L2, M2, N2 shunted by a negative coefficient resistance O1, 02 and a fixed resistance P1. P2 in series. This combination keeps the voltage across its load constant by absorbing the current due to failure of any one of the subsidiary loads, and also keeps constant the voltage across each main load despite changes in the main current. The combination of a negative-coefficient resistance and a constant resistance in series may be connected as a shunt to a circuit across points which are required to have a certain potential difference, or as an " inverted fuse," that is to shortcircuit the points from which a load is removed. The sudden voltage impulse due to the change from low to high current in the resistance may be detected at another point in the system to indicate failure of a load in the constant current circuit. The loads may be amplifier stations of a transmission system supplied with power via a constant current circuit. Fig. 3 shows a constant current circuit consisting of loads L1, L2, L3, L4, which may be valve filaments in a repeater station of a transmission system. In parallel with each load is a negative coefficient resistance 1a ... 4a and a relay 1b ... 4b which serves as the constant resistance. If any load fails, increased current flows through the resistance and operates the relay, which closes an alarm circuit. In the arrangement shown in Fig. 5 input power is supplied at S to a tuned circuit comprising an inductance L and condenser C in series. The load circuit O is connected across a rectifier bridge R. A negative coefficient resistance T1, T2 in series with a fixed resistance is connected at x or y or in both places. The negative coefficient resistances may be silver sulphide, uranium dioxide, or the material known under the Registered Trade Mark "Thyrite." Fig. 6 shows an arrangement for maintaining constant voltage over a large current range. A negative temperature coefficient resistance a is arranged in series with a constant resistance c in parallel with a series combination of negative temperature coefficient resistance b and constant resistance d. The resistance d may be shunted by a further combination of negative coefficient and constant resistances.

Abstract: 301,415. Soc. Anon. des Distilleries des Deux-Sevres. Nov. 29, 1927, [Convention date]. Addition to 296,974. Acetic acid.-In the extraction of acetic acid from its aqueous solutions by a solvent such as amyl acetate having a boiling point above that of acetic acid but below 150‹ C. as described in the parent Specification, when the aqueous acetic acid contains matters such as mucilaginous matter which would hinder the separation in the extraction column (as is the case with acetic acid from cellulose fermentation) the acid is vaporized and led into the middle of the separating column 3 which receives solvent from the tank 2. The column 3 is heated at 28 and vapour of water and solvent escapes at the top and is condensed at 26, separating into two layers in a vessel 27. The solvent is returned to the column from the vessel 27 and the water is rejected. There flows off at the bottom of the column 3 a mixture of solvent, acetic acid, and a small quantity of water which is taken to a column 6, the rest of the process being as described in the parent case. The process, and that of the parent Specification and Specification 300,246, may be carried out at atmospheric or above or below atmospheric pressure.

[Also in Division G1] In a damped oscillator type proximity switch, feedback is varied with the oscillator output to provide a SNAP-ACTION IN/OUT of OSCILLATION, to avoid the need for a subsequent trigger circuit. As shown, a Colpitt's oscillator Tr 1  has a capacitance-diode (or voltage sensitive capacitor) Co controlled by overall feedback through R 1  to vary the "feedback factor" of the oscillator. The oscillator output is amplified by Tr 2  and rectified by diode D to apply bias of a polarity that the output of Tr 3  increases as the oscillations decrease, whereby capacitor-diode Co further reduces oscillation. A recorder may be connected to the output of Tr 3 . Applications.-Counting objects; measuring length of objects moving at a predetermined speed; tachometer generator used in conjunction with a driven magnet-wheel.

Abstract: 1450624 Channel inductor ALLMANNA SVENSKA ELEKTRISKA AB 25 Jan 1974 [26 Jan 1973] 03527/74 Heading H5H An inductor for a channel induction furnace, ladle or other melt container comprises an electrically conducting frame (Fig. 6, not shown) lining compound 19 packed within the frame, an inductor coil 21, and an iron core comprising a first part 18 fixed to and reinforcing the frame and a second core part 32 detachably secured to the first part. Each core part is L-shaped to form a closed loop core when secured together. Keyhole slots 34, 35, 29 in opposite end plates of the frame receive the horizontal limbs of the core 18, 32, the absence of conducting frame material in the region 29 between these limbs reducing the risk of induced currents in the frame. No insulating interruptor is thus required in the frame. A short circuited ring of copper or aluminium surrounding each keyhole slot reduces leakage flux. Water cooling channels reinforce the frame and a water cooled flange 25 is provided for attachment to a furnace. A cooling jacket 22 surrounds the coil 21. The two core parts 18, 32 are strapped together and the first core part 18 is welded to the frame. This construction enables the melt channel 20 in the lining to be more closely coupled to the coil 21.
