Title: Improvements in fabric draw-off means for knitting machines
IPC: D04B15/88
Filed: 1966-06-28
Abstract: 1,116,135. Knitting-machines: takeup mechanisms. TEXTILE MACHINE WORKS. 28 June, 1966 [6 July, 1965], No. 29007/66. Heading D1C. A straight bar knitting machine with fixed spring bead needles 17 comprises a takeup mechanism having welt hooks, fabric take up hooks 45, a second set of fabric take up hooks 171 which disengage the fabric take up hooks 45, and a fourth form of take up mechanism comprising reels with hooks. The machine produces a turned welt and the welt hooks take up the welt then return it to the needles. At this point a bar with fabric take up hooks 45 engages the fabric and is pulled back by a wire 70 and weight. A deflector bar 105 pushes the fabric down as the hooks 45 come up to engage the fabric, thus assisting this engagement. A third fabric take up means comprising hooks 171 engages the fabric at the same time as the other hooks 45 these are moved by straps tensioned by weights, the return movement being made by a pawl and ratchet controlled by a cam on the machine. A cam (281) controlled lever 271 raises the hooks 172 in their forward position and then lowers them to engage the fabric. Both sets of hooks pull the fabric off until the bar (42) with hooks 45 is stopped by a fixed part of the machine and then only the hooks 171 are operative. The levers 271 are disengaged as the hooks 171 move back by abutment against the front bed 16 of the machine. A fourth take up means comprises reels (317) with hooks (318) which rotate in the take up direction. As hook members 171 reach the back position they rise slightly and a strip of felt disengages the fabric therefrom with the aid of the reels (317) which continue the take up process.

Title: Improvements in the construction of airplanes
IPC: B64C3/00
Filed: 1929-09-26
Abstract: 336,761. GÚrin, J. Sept. 26, 1929. F u s e l a g e s ; framework; planes, construction of. - Lifting surfaces and fuselages of aeroplanes are built up from juxtaposed box elements secured on spars, each box element being composed of a number of metal sheets flanged inwards at the edges and assembled by riveting juxtaposed flanged edges which form internal stiffening-ribs whilst leaving the external surface smooth. The spars are constituted by elements, each of which presents a cross section of constant external dimensions and the relative spacing apart of which is constant for several types of machine whilst the length, the thickness and the material are variable, according to the stresses to be supported. The boxes are provided with apertures for the passage of the spars, the dimensions and spacing apart of these apertures corresponding to those of the spars. Fig. 1 shews wings built up from box elements 1 threaded on tubular spars 2, the boxes 1 having apertures formed in ribs 3, Figs. 2 and 3, flanged at 5 to slide on the tubes 2. The boxes are secured at the outer ends of the planes by locknuts screwed to sleeves or rods on the ends of the spars. One element 2a of the box 1 is adapted for the attachment of bracing struts. In a modification the tubes 2 are arranged one at the leading edge and two near to the maximum thickness of the wing section. A box, Figs. 11 and 12, suitable for a variable-area wing of the .type described in Specification 302,277 comprises four long ribs 13 and intermediate ribs constituted by the flanged edges of the covering elements which are riveted together. Ribs 13 have holes 14, 15, 16 with flanged edges 17 to fit on the spar tubes. A false spar is constituted by plates 18 riveted to ribs 13 and to the covering elements. The ribs are cut away to allow for movement of the variable surface, the rib rollers, shewn dotted in Fig. 11, slide in channels riveted to the false spar and to the ribs 13. The lower part 27 of the covering is hinged at 28 and secured by screws 29 to a longitudinal channel member 30. The portion of the covering between the member 30 and the trailing edge is loose and is kept in position by springs 32. The rivets 33 of the end ribs of the box alternate with apertures 34 which receive the rivets of the juxtaposed box and vice versa. Similarly internally and externally flanged lightening holes in the centre part of the end ribs serve as dowels to locate juxtaposed boxes. When applied to wings having fixed surfaces the ribs 13 are continuous and the channel slides are omitted. Fig. 5 illustrates a fuselage built in three parts from box elements 1 having tubular spars which are composed of elements 2, 2<a> arranged to suit the contours of the fuselage, these being connected together by reinforced intermediate boxes 1<b>, Fig. 6. The inwardly flanged covering elements forming the boxes are riveted to bulkheads 3 having flanged apertures 5; intermediate bulkheads may also be provided. Arrangements involving sets of three and four spars are illustrated.

The intermittent D.C. for energizing the magnets 1, 2 is supplied from a battery 25 through an interrupter 8, rheostats 9, 10 separately controlling the electro-magnets 1, 2. An iron armature 11 is carried on a vibrator reed 12, which also carries a contact 14 engaging a fixed contact 13. The pick-up unit is carried in a pistol shaped casing 15, Fig. 2, through which the end of the test magnet core 4 projects slightly, this end being of hemi-spherical shape and applied to the metal to be tested, which has a corresponding indentation made in it by a special tool. The case 15 also carries a lamp 17 controlled by a switch and arranged to illuminate the operating nose end 16. The receiver unit C comprises twin sets of ear-phones 18,19 connected through a transformer 20 to the circuit containing the vibratory contacts 13, 14. A pilot light 21 is also provided for visual indication. The hemispherical end of the test core 4 is applied to an indentation in a standard steel plate and the rheostats 9, 10 are adjusted until the electromagnet 2 attracts the vibrating armature 11 to such an extent that the contact 14 is moved so far from the contact 13 that these contacts do not engage as indicated by silence in the earphones 18, 19. The test core is then applied to an indentation in the metal to be tested. If this is up to standard silence is again obtained, but if it is below standard the vibrating contact 14 intermittently engages the contact 13 and causes sounds in the phones.

Oct. 2, 1930, No. 29506. Convention date, Oct. 10, 1929. Void [Published under Sect. 91 of the Acts]. [Class 51 (ii).] A continuous glass furnace having a movable sole 32 carrying the posts 6 is heated by independently regulable burners 10 and divided by vertical partitions 13, 14<1>, 14<2>, 17, 18 into compartments corresponding to the successive operations in glass making. The furnace comprises outer and inner walls 1<1>, 1<2> enclosing an annular space 2 with a roof 23 closed at the bottom by a fixed sole 3<1> and a central movable sole 32 mounted on rollers 5. The fixed sole is hollowed out to form a basin 4 to catch waste glass. The burners 10 are placed centrally of the furnace, the flame passing radially through the working chamber 2 and escaping to the recuperators through flues 11 near the bottom of the outer wall 1<1>. Between the casting zone C and the reheating zone R is a screen 13, Fig. 5, reaching down to the level of the rotary sole. Each pot from the position 6<24> after casting is returned to the reheating zone R through the door 122, the sole having moved so that the free space has moved to position 6<1>. In the charging zone E the pot passes beneath the vertical screens 141, 142 supporting horizontal screens 15, and the charging operation is performed through an opening 12<1>. The pots then pass in turn into the melting and refining zones F; A, combustion in which is separately regulable. Mechanical stirring devices may be arranged in the refining zone, with screens similar to the screens 14<1>, 14<2>. The screen 17 separates the refining zone from the cooling zone B the heat of which is regulated by the flues 11, and the screen 18 separates the casting zone C from the cooling zone. The screens 141, 14<2>, 17, 18 allow the pots to pass beneath them. Removable plugs in the outer wall 1<1> allow the glass collected in the basin 4 to be run out. A hydraulic joint 7 is provided between the parts 31, 3<2> and the track for the rollers 5 is vertically adjustable to regulate the height of the movable sole. An inside rim 9 on the movable sole puts the inner basin 4 out of action when the burners are at the centre of the furnace and the movable sole projects over the basin 4 so that hot glass cannot run into the free space 8. The burners may be otherwise arranged and the flame may be of horseshoe or circular shape.
