Title: Improvements in and relating to package-sealing machines
IPC: B65B57/04
Filed: 1920-08-18
Abstract: 171,760. Imrie, H., (Ginn, P. E.). Aug. 18, 1920. Paper and like bags, folding down mouths of after filling. - Relates to machines for sealing down the tops of cartons in which the cartons are moved through the machine by a conveyer while the front and rear flaps are folded down, glue is applied to one of the side flaps, the side flaps are folded, and the closed carton is received by a conveyer which holds the flaps closed until the adhesive has set. The filled cartons 1, Figs. 2 and 5, are fed to the machine by a belt 15 against a stop 42 and into the path of a plunger 29, Fig. 5, which transfers it to a guideway 34. In the case of an irregular feed of cartons and to prevent them from being crushed, a stop device. Figs. 2 and 4, is provided. During a regular feed, the stop 43 is kept in the position shown in broken lines in Fig. 4 by the advancing cartons, but if a gap occurs, the stop is swung into the position shown in full lines and is locked by a latch 46, thus stopping the feed until the plunger 29 commences its backward stroke, when a bar 54 is retracted by a cam against the action of a spring 57 and a pin 55 on the bar disengages the latch. The stop 43 then yields and allows the feed to continue. The cartons which have been advanced to the guideway 34 are engaged by pushers 61, Fig. 2, on chains 57 passing round sprocket-wheels 58, 59, and are conveyed past folding and gumming mechanism to a drying- device. Each pusher 61 has a tail 63 which rests against a guide 64 whereby it is held in the operative position, having been initially brought to this position by a plate on the sprocket-wheel 58. The carton is first acted upon by a rear folder 6, Fig. 2, and is prevented from tipping forward by a spring catch 79 which subsequently yields to the action of the feed and allows the carton to be carried under a front flap folder 7, Fig. 5, having two pairs of elements 83, 84 which turn over the flaps 4, 5 into the position shown in Fig. 10. In this position, the flap 4 passes between the glueing rollers 8, 9 whereby both sides are glued. A wire folder 88, Fig. 6, then turns over the flap 4 and another folder turns down the last flap 5. Presser-rolls 91 ensure adhesion of the flaps 2, 3, 4 and a grooved wheel 95, Fig. 6, acts on the edge 96, Fig. 12, of the package. The guideway 34 is formed with overhanging lips 93 adjacent to the folder 88, a bevelled part 94 facilitating the entrance of the packets. The lips 93 ensure correct folding of the top of the carton even if the sides are bulging. The packet then passes to a drying-device comprising endless bands engaging the top and bottom of the package and driven at a slower speed than the conveyer 57. The lower belt is capable of vertical adjustment so that different heights of packages can be accommodated. The lower part of the guideway 34 and the feeding- belt 15 are both vertically adjustable.

A two-part connector has at least one resilient socket which can be deformed by the sides of apertures in a clamping member to grip an inserted pin. Plug contacts 18, as shown in Fig. 4, having a pin 21 with a uniform diameter tip portion 27 and a reverse tapered portion 28 and socket contacts 19 with slits 29 in a sleeve 22 are carried in plug-and-socket portions 10, 11, Fig. 5. The socket contacts 19 pass through slots 25, Fig. 2, in a clamping-plate 23 pivotally mounted by a screw 24 on the socket 11 and rotation of the clamping plate 23 causes movement of the contact sleeve 22 from a wide portion of the slot 25 to a narrower portion and thus deforms the sleeve. The two parts are correctly engaged by means of locating tabs and a bayonet locking sleeve 32 also serves to rotate clamping plate 23. An alternative form of clamping member, which moves in the axial direction of the contacts, is shown in Fig. 7. In other embodiments the clamping plate is mounted for limited rectilinear movement, e.g. as in Fig. 12, where an insulating board 90 has conducting tracks connected to sockets 93 and a clamping or locking bar 96 is mounted to slide parallel to the edge of the board.

Abstract: 718,196. Electrostatic switches. LORD PRESIDENT OF THE COUNCIL. Jan. 26, 1953 [Oct. 24, 1951], No. 24906/51. Class 38(5) [Also in Group XXXVI] The moving electrode of the electroscope of a radiation dosimeter is arranged to close a contact to operate an electro-acoustic device when in the discharged condition. As shown a metal or metallised rectangular box 1 contains a terminal block 2 electrically connected to the box and carrying a metallised quartz fibre 3. A profiled electrode 4 insulated from the box is charged by means of a spring-loaded contact button 5 when the fibre is deflected to the full line position shown. As the charge leaks away the fibre moves towards the dotted line position and the electrode 4 is so shaped that the fibre accelerates and contacts a metallised quartz loop 6 carried on an insulated block. The fibre short-circuits a resistor 13 in the grid circuit of pentode oscillator v. This oscillator is normally arranged to " squeg " at 100 CS but when the resistor 13 is short-circuited the oscillator generates continuous waves at 2 Kcs. These notes are produced by a small speaker or telephone ear-piece 7 the change in note indicating that maximum radiation dosage has been reached. Condenser vane 15 is provided to adjust the capacity of electrode 4. Quartz fibres 3 and 6 are provided with heavy metal coatings of dissimilar metals to avoid sticking. In a modification a rectangular plate is substituted for electrode 4, the quartz fibre being arranged at right angles to the plane of the plate so as to be attracted towards the edge by a charge in the plate.

Abstract: 173,278. Taylor, A. M. Aug. 30, 1920. Protective arrangements; systems depending on the use of static transformers; systems depending on the use of two or more machines.-To reduce the stress in the cable insulation of a three-phase supply system, a single-phase electromotive force of three times the frequency of the three-phase system is introduced between the neutral point of the generator or transformer and earth by means of a motor-generator or by the static frequency changer described in Specification 8853/11, [Class 38 (ii), Electric currents, Converting &c.]. When the electromotive force of the triple frequency current is above a predetermined value a third harmonic of this current is also introduced to give a deformed electromotive force which will give the best results. The neutral point of a generator or transformer G, Fig. 1, is connected to earth E through a resistance R and the secondary coil S of a frequency changer F, C. In the modifications shown in Fig. 2, the frequency changer FC is provided with star-connected primary coils arranged to over-saturate the cores while the secondary coils 1, 2 and 3 are arranged in incomplete delta.
