Abstract: 1,127,427. Laminatingap paratus. LANGSTON CO. 12 Aug., 1966 [17 Aug., 1965], No. 36232/66. Heading B5N. A single facer machine for corrugating sheet material 46 and gluing the corrugated material to a plain sheet of facing material 48 to form a sing efaced board 50, such as paperboard, comprises upright side frames 14 supporting a glue mechanism between them, the mechanism including a glue applicator roll 62 having circumferential grooves 64 therein, a metering roll 66 and clean-out fingers 82, each of which is disposed partly in one of the grooves on the roll 62 and lies entirely between the vertical planes containing the respective axes of rotation of the rolls 62 and 66. The fingers 82 are free floating, their upward movement being limited by a shaft 84. The gluing mechanism is supported on brackets 76 which are fixed to a shaft 78 rotatable about its axis under the action of pneumatic motors 72 towards and away from a lower corrugating roller 18 for maintenance purposes. Fine adjustment of the gap between rollers 62 and 18 is effected by adjustment of screws 100 threaded through shafts 96 also connected to shaft 78. The web of material 46 is led over a spreader bar 38 and conditioned under a shower 40. A slitter knife may be provided for trimming its side edges. It is then corrugated under heat and pressure between an upper roller 20 and the lower roller 18 and is guided around the roller 18 by guide fingers 54 which are also accommodated in the grooves of the roll 62 and supported on a bar 56. Adhesive is applied to the crests of the corrugations as the material passes between the nip of the rollers 18 and 62, the fingers 54 being cut away slightly at this point to allow slight fluffing of the material. The corrugated material 46 is joined to a web of plain material 48 between the nip of the roller 18 and a lower pressure roller 30. The rollers 18, 20 and 30 may be heated. The roller 30 is supported at its ends by arms 32 pivoted at 34 and it may be moved away from roller 18 by pneumatic motors 38. Similarly, roller 20 is supported on arms 22 pivoted at 24 and is movable away from roller 18 by pneumatic motors 28.

Title: Braiding machine
IPC: D04C3/00
Filed: 1973-08-07
Abstract: 1393836 Braiding-machine D RICHARDSON 7 Aug 1973 [14 Aug 1972] 37439/73 Heading D1C In a tubular braiding machine having two sets of contra-rotating yarn carriers the carriers are guided without the use of a track plate, solely by engagement with the horndogs, and are rotated to maintain a point thereon substantially on a line joining the carrier axis and the braiding point. Each horndog of the two sets 20a, b comprises upper and lower plates 21a, b; 22a, b having pockets 26a, b for receiving the carrier spindles. The horndogs are rotated by horngears 32a, b connected to the dogs by posts 33. The horndog spindles 15a, 15b carry stationary sun gears 35, 40; 43, 44 respectively. A pair of planetary gears engages each sun gear, the pairs associated with each horndog being offset by 90. Each carrier spindle carries a gear 50 meshing with the planetary gears. Each carrier moving clockwise around the braiding point is carried clockwise around an outer arc by one horndog and anticlockwise round an inner arc by the next. To maintain the desired constant disposition of the carrier the first set of planetary gears 41, Figure 5c slows its clockwise rotation about its own axis. The next set 45 more than compensates for the anticlockwise rotation. Similar rotation is effected by gears 46, 36 for carriers moving anticlockwise. The carrier spindles carry semi circular flanges 52, 53 defining tracks 53, 54 for rollers 56-59 carried by the horndogs. Each spindle is held in a pocket by an adjacent roller engaging the corresponding track. As the carrier approaches a change-over to an adjacent horndog the roller e.g. 56a Fig. 6c approaches the end of its track. The roller 58b of the receiving horndog is about to engage track 55 and take-over guidance of the carrier.

Filed: 1974-08-28
Abstract: 1485303 Automatic control WATKIN ELLIOTT SYSTEMS ENGS Ltd 18 Aug 1975 [28 Aug 1974] 37592/74 Heading G3N A control apparatus, for a sequence or batch treatment process for articles conveyed through a number of process stations, effects an increase or decrease of the speed of a conveyer so that the effective length of the conveyer is an exact multiple of the length associated with an article or batch of articles. As shown, a batch system for the formation and baking of pies comprises a former 10, transfer devices 11, 13 and a conveyer 12 whereby pies are placed in a rester 14 in which the pastry of the pie is allowed to prove. The pie is subsequently passed by a conveyer 16 and transfer devices 15, 17 to an oven 18 and, finally, by a transfer device 19 to a cooler 20. The elements 10-18 are phase and speedcontrolled by pulses on lines 30-32, from a pulse generator 28 which incorporates a crystal-controlled osciallator, associated frequency-dividers and a variable pulse-rate master clockpulse generator providing overall speed-control. The speeds of the rester and oven, to effect satisfactory preparation of the pies, are set by an operator in dependence on batch length. For the oven 18 the speed of the conveyer is sensed by a pulse generator 40 and a control circuit 41, Fig. 3 (not shown), adjusts a drive motor 38 through a device 39. A control circuit 70, Fig. 4 (not shown), for the conveyer of the rester 14 is similar to that of the oven but stretch is compensated by determining by pulse generator 66, 67, the speed of driven and idler sprockets and modifying the control of a motor 65 accordingly. Items 10-13, 15-17 and 20 are cyclically controlled, by signals on lines 30, 32 by control devices, 85-90, and 47, in dependence in the desired operating speed. The transfer device 19 is operative, through a divider 33, from line 30 and comprises an unloading arm intermittently operated by a motor 29. The system employs digital techniques but it is stated that analogue devices can be employed for  parts of circuits. Alternative analogue and digital cyclic control devices are described in Figs. 5, 6 (not shown).

Filed: 1973-08-09
Abstract: 1433393 Storage system HONEYWELL INFORMATION SYSTEMS Inc 9 Aug 1973 [5 Oct 1972] 37741/72 Heading G5A Variable masking apparatus for simultaneously accessing under program control a variable number of bytes b of information stored in groups of i bytes per group in any of n modules of storage operable in m different storage modes includes means for masking selected ones of the b bytes. As described the storage comprises a main memory 301 (Fig. 3) and a high speed multimodular buffer memory 304, data from the main memory being transferred to the buffer memory if it is not already stored therein when requested by a CPU or input output unit. An address from the CPU is stored in a memory address unit 307. Bits 20-26 of the address are utilized to access a buffer directory module 305. Bits 8-19 are compared in comparator 308 with data in row upper and row lower fields of the buffer directory module and if coincidence occurs a hit upper or hit lower signal is fed to buffer control circuitry 303. Bits 20-29 are utilized to address the data buffer modules 304 U, 304 L where data is sorted in one mode in upper and lower banks of the modules each having 128 columns holding 32 bytes in two rows, i.e. 128Î2Î32 mode. A 4 byte data word is read out from an upper or lower bank of the upper or lower module by logic circuitry (Fig. 4, not shown), validity bits in the address indicating the validity of the data stored in the buffer location. When no match occurs, each of the four modules of main storage 301 are accessed to retrieve 8 bytes of data for loading into the buffer store, 4 bytes also being fed to the CPU. Three further accesses without data transmission to the CPU are then made so that 32 bytes are entered into the buffer store. In a second mode of operation (Fig. 5, not shown) the buffer memory has only upper banks in each of its modules each storing 128 half pages. In a further mode of operation (Fig. 6, not shown), the 256 x 2 x 16 mode, each module stores 256¢ pages. Alternatively in the 128Î2Î32/16 mode (Fig. 7, not shown) each module stores 128 pages in upper and lower banks which are themselves subdivided into two. A mode of operation is selected using the circuitry of Fig. 8E (not shown). Addressing for either the CPU or input/output device is effected via AND gates (801E, 802E). If the 128Î2Î32 mode is required further AND gates (804E, 806E) are primed to access the memory module whereas if the 128Î2Î16 mode is selected AND gates (807E, 808E) are primed. Logic circuitry (8A-8D, not shown) is used to generate inter alia masking signals.

Abstract: 881,684. Extrusion apparatus. BURGESS ENGINEERING STOKE-ON-TRENT Ltd. July 21, 1960 [Nov. 10, 1959], No. 38017/59. Class 87(2). Apparatus for extruding plastic material such as dough in strip form comprises a driven feed roller 12 in contact with the material 14 in a container 10, a driven pinning roller 16 located below and to one side of feed roller 12 for assisting in the feed and for determining the thickness of the strip to be extruded, and a delivery roller 13 of larger diameter than rollers 12, 16 which is located below roller 12 for delivering the extruded strip, the ratio of the rate of rotation of the delivery roller 13 relative to that of the feed roller 12 being 1À316, the diameters of rollers 12, 13 having a like relationship. The feed roller 12 has a fluted surface while the other rollers are smooth-surfaced. The pinning roller 16, which is of the same diameter, and driven at the same speed but in the opposite direction as roller 12, is mounted between a pair of arms 15 pivotally mounted on standard 111 coaxial with the axis of feed roller 12. These pivotal arms 15 are in turn pivoted to the upper ends of rods 17 having eyed lower ends mounted on eccentrics 181 carried by a transverse shaft 18, the turning of which by a handwheel (not shown) varies the throw of the eccentrics 181 and hence the spacing of the peripheries of the delivery roller 13 and the pinning roller 16 and the thickness of the extruded strip. As the feed roller 12 rotates anticlockwise and in the opposite direction to the pinning roller 16, material 14 is drawn from the container 10 and forced into the space A in a state of compression. From this space, the material is extruded through the gap between the peripheries of the delivery roller 13 and the pinning roller 16 and is carried on the periphery of the latter until, e.g. in the case of dough, it falls into baking tins 34 supported on the upper surface of a chain driven conveyer. Transversely arranged knives 32, 33 strip any adherent dough from the lower peripheries of rollers 13, 16 respectively. In addition to extruding dough, the apparatus can be used for extruding marzipan, paste, jam or other confectionery fillings in strip form, or in other industries where a plastic material is required to be extruded continuously in an unbroken strip of uniform width and thickness.
