The carton tray blank shown (Fig. 3) includes corner portions 15 which are joined to the ends of adjacent wall panels by fold lines 21, 22 and are each subdivided by further fold lines 16, 17 into a central sector 18 and two lateral sectors 19, 20. The tray is erected by folding the corner portions inwardly, and edge flap panels 27, 28 downwardly into a plane parallel to the bottom of the tray. The lateral sectors 19, 20 are sealed to the adjacent wall panels and connecting flaps 23 are folded over and sealed to the ends of the edge flaps 27, 28. During the latter operation, incisions 25, 26 cause the central sector 18 to be further subdivided into a middle portion 29 (Fig. 2) which is substantially perpendicular to the bottom and marginal portions 30 which are brought into contact with and may be sealed to the lateral sectors 19, 20. A cover 31 which may be of transparent foil (Fig. 1) has weakening lines 32, 33 which define a removable section 37, marginal strips 34, 35 and two tear-off tabs 36. The cover on its underside and the blank on its side corresponding to the interior of the tray has a fluid-tight coating, e.g. of a plastics material such as polypropylene. The cover and tray are secured together by the application of sealing stripes or by heat and pressure to fuse the coatings. The connecting flaps (23) may be joined to adjacent edge flaps 27, 28 by intermediate edge flap portions (50, 51), Fig. 4 (not shown), which are folded over and secured to the edge flaps, Figs. 5, 6 (not shown). The portions below the tearoff tabs 36 may be left unsealed to provide leaking gaps for generated vapours if the carton contains food and is heated. The cover may have on its underside a continuous incision line (56), Fig. 7 (not shown), which defines an inner tab (60) and only partially penetrates the cover and an incision line (57) defining a tab (58).

Abstract: 1,251,074. Static converters; A.C. motor control. NATIONAL RESEARCH DEVELOPMENT CORP. 6 June, 1969 [7 June, 1968; 2 Jan., 1969], Nos. 27259/68 and 325/69. Headings H2F and H2J. ' In a static frequency multiplier A.C. is rectified e.g. by a diode bridge D3 (Fig. 3) and fed to an induction motor M via a coupling capacitor Cl. The D.C. component of the rectified current is by-passed by a resistor R and blocked by Cl so that current at twice the supply frequency passes through the load, as illustrated, Fig. 2. The by-pass circuit preferably should have selectively high inductance so as to block the A.C. component. Various full-wave, half-wave, polyphase and single phase rectifier arrangements based on the basic circuit, Fig. 3, are described. For instance, Fig. 5 (not shown), illustrates a 3 phase to single phase half wave rectifier arrangement and Fig. 21 illustrates an arrangement for supplying a three-phase motor from a three-phase frequency multiplier. In a polyphase arrangement, Fig. 16 (not shown), to change the motor speed one phase may be open-circuited by a switch to give a frequency multiplication of four instead of six. Switching arrangements to selectively convert a circuit operation from full-wave to half-wave with consequent change in the output frequency, are also described, e.g. Fig. 9 (not shown). The by-pass resistor may be variable, also variable resistors may be inserted in the A.C. input to the rectifiers to vary the voltage applied to the motor and thereby change its speed. The rectifier elements may be thyristors. The application of the multiplier circuit to fan motors e.g. hair dryers, wherein the by-pass resistors may also function as heaters, is described.

Abstract: 1295141 Cleaning coke oven door flanges ALLIED CHEMICAL CORP 3 July 1970 [18 July 1969] 32463/70 Heading F2N A device for cleaning the flanges 13 of a coke oven door 10 (Fig. 1) comprises a cleaner head 12 pivotably mounted on a carriage frame 51 via a pair of counterbalance arms 52. The counterbalance arms 52 are also connected via spring units 61 to the frame 51 and the height of the cleaner head 12 may be adjusted by nuts 64. A bell-crank 54 is connected via turnbuckle 66 to the head 12 at 67, the other arm of the crank being resiliently secured to frame 51 at 71 so that adjustment of the turnbuckle can cause the head to be inclined from the vertical when at rest. The carriage frame 51 is connected to a trolley with rollers 76, 77 running on parallel tracks 78. A coke oven door to be cleaned is presented to the cleaner head 12 and the ram 80 operated to advance the head towards the door. The head 12 is adjusted by the tumbuckle 66 so that the first engagement is between an inverted U- shaped slot 14 on the door and a spring-loaded finger 38. Subsequent movement of the head engages a profiled roller 44 on a co-operatingly profiled head 15 on the door, thus ensuring correct registration of head and door. The flexibility required to achieve this is achieved by making pivots 53, 57, 58 of the ball-jointed swivel bearing type. When in plumb position the head and door are locked together by clamps (97) (Fig. 13, not shown) on arms 91 after rotation of a crank-shaft (108). After cleaning the carriage frame 51 is retracted and the device centred by the ends of the arms 52 being engaged by guides (88) (Fig. 10, not shown). Scrapers.-Two scrapers progress round an endless path corresponding to flange 13. The scrapers 134 (Fig. 17) are spring-mounted on members 133 carried by the front section 132 of a scraper head 131, springs 135 allowing relative movement to prevent jamming on uneven deposits on the door. The scraper head 131 is mounted on parallel shafts 115 (118), the former carrying rollers 117, 116, and the latter bearing rollers 118, 119. The rollers run on wear strips 31 lining a pair of guides 25, 26 which are formed between Z-shaped strips 20, 21 (see also Figs. 1 and 2). The guides form the endless path for the carriage 30 (Fig. 17) and correspond in shape to the rectangular flange 13 on the oven door. To prevent the carriage 30 moving towards and away from the door a further guide rail 23 is provided on which guide rollers 128 run. Scraper drive.-A pair of endless chains 125, 127 run over sprockets 154, 155 on shafts 150-153, the shafts being placed at the corners of the rectangular guides 25, 26 (Figs. 1 and 2). Members 124, 126, mounted on carriages 30 (Fig. 17) are secured to links on the respective chains so as to move the carriages and scrapers when motor 156 (Fig. 2) drives shaft 150. The guides 25, 26 are cleaned by scrapers (147) (Fig. 18, not shown), mounted on shaft (143) which is attached to the chains 125, 127 by arms (142) and catches (144). The chains are adjusted and tensioned by moving the shaft bearings 161 by adjustment nuts 165.

In operation, the layers 4 are threaded through the apparatus to lie beyond the device 10. The device 9 is closed to clamp the stack tightly and the device 10 is operated to cut through the stack. The carriage 13, uncoupled from the chain 12, is pushed to the left of Fig. 1 and the device 15 grips the cut edge of the stack. The device 9 is released, the carriage 13 is coupled to the chain 12 and the belt 11 is operated. The stack is pulled out until the carriage 13 strikes the switch 16 which causes the device 9 to close and initiates another cutting operation. After cutting, the carriage 13 is disengaged, the device 15 is released and swung above the stack which then passes through the carriage and is conveyed by the belt 11 to the work table. The carriage 13 is displaced to the left or may run automatically in this direction if the upper frame rails are so inclined. To accurately align the longitudinal edges of the layers 4 as they emerge from the magazine 1, the edges are sensed by photoelectric means which control a motor 19 or 30 to axially displace a rod 23 carrying a roll 2. In one embodiment Fig. 3, the motor 19 drives a threaded spindle 20 which has a nut 22 non-rotatably mounted thereon. The top of the nut 22 is forked to engage into an annular groove of a ring 24 fixed to the rod 23. Switches 26 limit the travel of the nut 22. Pairs of rollers 25, 28 support the rod 23 and parts 29, conical externally and cylindrical internally, fix the position of the roll 2 on the rod 23. In another embodiment, Fig. 7, a worm gear motor 30 has a driving worm 31 meshing with a worm wheel 32 provided with a female thread by which a threaded spindle 33 is non-rotatably displaced. A nut 36 on the spindle 33 has a slotted collet 37 into which the rod 23 extends. (For Figures see next page)
