Title: Improvements in apparatus for drying webs of fabric
IPC: F26B13/04
Filed: 1933-05-19
Abstract: 402,676. Drying fabrics. GESSNER AKT.-GES., E., Aue, Saxony, Germany. May 19, 1933, No. 14586. Convention date, July 7, 1932. [Class 34 (i).] A drying chamber is subdivided by partitions into compartments, in each of which there is a separate conveyer which carries festooned fabric, the conveyers being so arranged that the speed of each can be independently regulated. For the formation of the loops, each compartment may be provided with a feed roller driven with alternate acceleration and retardation ; and the bars on which the loops hang may be rotated. In one form, there are two drying compartments I and II, each provided with an endless conveyer 14 working on rollers 15, these conveyers being separately driven. Hot air for drying enters through channels 17, and passes out through suction channels 18 to heaters 19, whence the air passes to the same or another compartment. By adjusting the heaters 19, the temperature of the air may be regulated separately for each compartment. After preliminary drying at IV, the web 21 enters compartment I, where the loop former VI lays the web in festoons on the conveyer. The web is fed to compartment II by rollers 24 and a travelling apron 25, which may be furnished with a spreading device. Other forms show various arrangements of adjacent and superposed chambers. In each case the loops increase in length as the web progresses from one compartment to another, the speeds of the conveyers being lower in successive compartments. The air may flow through the chambers in the opposite direction to the web, and its temperature may be raised from say 35‹ C. in the last stage of treatment of the fabric to 90‹ C. or more in the first.

Title: Improvements in or relating to the manufacture of slivers of bast fibre
Inventor: SATO KEISHI
IPC: D01H5/22
Filed: 1964-04-10
Abstract: In order to produce slivers of bast fibres, a band of the degummed fibres is divided longitudinally into strips, drafted, and redrafted in such manner that opposite edge portions of the strips are subjected to different drafts to give different amounts of longitudinal movement between adjacent fibres of the strips. The redrafting is preferably effected by passing the strips between conical rollers, the narrower end of one of the rollers being in operative association with the wider end of the other. The conical rollers may be coated with an elastomeric high polymer, such as synthetic rubber.  A process of sliver production in six steps is described.  In the first of these a band of fibres is split by a porcupine roller whilst being drafted and, whilst the fibres are passing through the same machine, they are given three further successive drafts including one in which conical rollers are utilised.  The sliver so produced is passed through a gill-box, through a tow-to-top conversion type of apparatus, then through a further gill-box, a lap-forming machine and a comber. The latter has means for removing dirt and nap by directing a current of air at the needle bars.

Filed: 1966-04-06
Abstract: 1,148,081. Digital data processing. GENERAL ELECTRIC CO. 6 April, 1966 [6 April, 1965; 14 April, 1965; 15 April, 1965], No. 15377/66. Heading G4A. In a data processing system the address field of instruction words of a programme may be modified using a number of auxiliary words (Figs. 2d-2j, not shown), the modification taking place after the instruction word has been read from memory but before the associated instruction has been carried out. The address field of a standard 24-digits instruction word comprises the first 15 digit (0-14), digits (15-17) forming a control field which indicates what form of modification of the address field (if any) is to be performed, and the remaining digits (18-23) forming an operation code identifying the instruction and indicating whether the word is a single or two-address instruction. If the control field has a value 1-6, the address field of a Fixed Location index word (Fig. 2d) is added to the address field of the instruction word and the instruction then executed uses the modified address. If the control field has the value seven then modification is performed by a P-sequence A.M.S. word (Fig. 2e) whose digits (18, 19) indicate whether the word is an index, an index pointer, or an index link. If an index, then its address field is added to that of the instruction word. If an index pointer, its address field indicates an indexing quantity outside the programme, which quantity is again to be added to the address field of the instruction word. If an index link, then its address field specifies a Remote A.M.S. word (Fig. 2f) which may be similarly classed as an index, an index pointer or an index link, and which further continues the modification of the instruction word. If the digit 21 of a P-sequence A.M.S. word has the value 1, modification is performed by an Indirect Address word (Fig. 2g) which is specified by the address field of the P-sequence A.M.S. word, the address of the Indirect word replacing the address previously developed. The Indirect Address Word may then call for further modification using Indirect A.M S. words (Fig. 2h) similar to the Remote A.M.S. words. For twoaddress instruction words, the second address may be developed using P-sequence S.A.S. words (Fig. 2i) and Remote S.A.S. words (Fig. 2j). In operation, the address field, the operation code and the control field are transferred from memory 10 into registers D, I, and Q, respectively, and the relevant parts examined. Sequences of auxiliary words are then generated to modify the instruction word, which in its final form, is interpreted by an operations control unit 318 and the instruction then performed using adder 492 and register E. Each in - struction word read out from the memory is addressed by P-register and a 25th digit of the word stored in the memory is examined by a parity check and generation logic 316, the latter also providing the correct 25th digit when the word is re-entered into the memory.

Abstract: 1,260,251. Packaging machines. J. J. SHUTTLEWORTH. 1 April, 1970 [28 April, 1969], No. 15418/70. Heading B8C. In a packaging machine comprising a horizontally reciprocable platform 45 to which objects are fed by a first conveyer 13, and from which the objects are lifted by a vacuum head 16, the platform 45 then being retracted to the left and the vacuum head being lowered to push the objects into a box 15 on a second conveyer 12, pads are placed between layers of objects in the box 15 by means of suction cups 131 which remove a pad from a stack 115 and transfer it to a carriage 150 secured to the underside of the platform 45. When the platform 45 is retracted to the left, the pad is stripped from the carriage 150 by stops 200 and falls into a funnel 40 from which it is pushed into the box 15 by the descending vacuum head 16. The platform 45 has a vertical track 62 which is pushed by a roller 61 carried by a lever 60 rotated by a piston and cylinder 50, 51 to reciprocate the platform 45. Rollers (not shown) on the platform 45 engage cam tracks 42 carried by the funnel 40 such that the latter is lowered as the platform 45 is retracted. The stack 115 of pads is carried in a rack 100 which is adjustable by means of threaded shafts 102. The suction cups 131 are carried on an arm 130 keyed to a shaft 125 rotated by an hydraulic motor 136 to place a pad on horizontal frame members (165, Fig. 1) and on lower ribs 160 on the ends of the side members of the carriage 150. On retraction of the platform 45 and the carriage 150, the pad abuts stops 170 carried by the horizontal frame members (165). On subsequent movement of the carriage 150 towards the first conveyer 13, the pad is pushed by lugs (180) on the carriage over the stops 200 so that on subsequent retraction of the carriage 150 the pad is stripped therefrom by the stops 200.
