Title: Electric current limiting arrangement
IPC: H01H71/12
Filed: 1924-01-25
Abstract: 223,460. Kambayashi, K. Jan. 25,. 1924. E l e c tromagnetic switches; conducting liquid switches.-A maximum current limiter comprises a sealed glass vessel containing a glass float 6 with an iron core 4 at the lower end and an openended tube 5 at the upper end. The vessel contains also a rod electrode 2 and a tubular electrode 3 surrounding it, the electrodes being normally connected together by conducting liquid 7 which fills the container up to the level shown. The lower end of the container carries a coil 8 in series with the load 10 and a coil 9 in shunt with the load and in series with a resistance 12. When excess current flows in the load circuit the float is drawn upwards and the open-ended tube progressively shrouds the electrode 2 thus progressively reducing the current until finally no current passes in the series circuit. In a modification, the tube is made of metal and constitutes the outer electrode while contacts hinged to it normally engage the inner electrode. The open-ended glass tube first pushes the contacts out of engagement with the inner electrode and then progressively covers it. Alternatively, a loose contact piece, 3<1>, Fig. 4, may be arranged on the inner electrode and normally resting on projections from the' metal container. The glass tube first lifts this contact out of engagement and then shrouds the inner electrode.

Filed: 1920-01-27
Abstract: 138,344. Krause, W. March 9, 1918, [Convention date]. Addition to 138,339. Couplings, disconnectible.-Relates to joints or couplings for sectional pipes in the irrigation system claimed in the parent Specification, and of the type in which hooks carried by levers pivoted to the sides of one of the pipes are adapted to engage studs on the other pipe, drawing the pipe ends together when the levers are rocked. The invention comprises an arrangement in which the pipe end carrying the hooks is also provided with guides which support and guide the hooks in a straight line parallel with the pipe axis when the lever is rocked to effect the coupling. In the arrangement shown in Fig. 1, pins 71 projecting from a sleeve 70 on one pipe end, are engaged by hooks 72 pivoted at 73 to a lever 74 mounted on trunnions 75 on a sleeve 69 fixed to the other pipe end. By pulling down the lever 74 from the position shown in dotted lines to that shown in full lines, the coupling members are drawn together, the hooks 72 sliding on guides or supports 76 fixed to the sleeve 69 and arranged so that the hooked ends move in a horizontal line parallel with the pipe axis. In a modification, the lever 74 is weighted at its upper end, and is adapted to be tipped over by engagement with a projecting arm or horn on the other pipe end when this is placed in position. In this form, the weight may be secured to the arm 74 by a catch which is adapted to be released by pulling a cord trained on rollers 82, 83 as shown in Fig. 4, an additional arm 79 disposed at an angle to the lever 74 being provided in this case. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the arrangement shown in Fig. 2 (Cancelled), in which the coupling is effected by notched and toothed arms 65, 66 respectively, engaging in a plane passing through the pipe axis.

[Also in Division B8] Flat bags having rectangular bottoms are made from a longitudinally folded web H intermittently fed in steps corresponding to the width t of the bags to processing stations a, b, c and d. At station a, a separating and welding beam 4 reciprocable towards and away from the web applies a short separating weld seam 6 to define the bottoms of the bags. At station b, a flat supporting arm 8 reciprocable in a direction 13 is located between the plies of the web and carries an expansible former 9 to spread the plies apart in a direction normal to the web. Electrically heated separating and welding jaws 23, 23<SP>1</SP>, 24, 24<SP>1</SP> at station c movable in a direction normal to the web on a support 25, nip off, the triangular pockets Z, Z<SP>1</SP> formed on expansion of the former. Pairs of handles 35 may be applied to the web at a station intermediate stations c and d by known means. At station d a second welding and separating beam 31 extends the weld seams 6 and serves the bags. As shown in Fig. 6, the expansible former comprises two flaps 10, 10<SP>1</SP> mounted on drive pins 14, 14<SP>1</SP> in turn mounted on the arm 8 and carrying pinions 16, 16<SP>1</SP> at one end which engage with racks 17, 17<SP>1</SP> carried by a common thrust bar 18. As the arm 8 is moved into the web, an abutment 19 prevents movement of the bar 18 and the pinions 16, 16<SP>1</SP> co-operate with the racks 17, 17<SP>1</SP> to open the flaps 10, 10<SP>1</SP> from their parallel, closed position to that shown. A spring 21 returns the flaps to their closed position on retraction of the arm 8. The position of the abutment 19 may be adjusted to control the amount of expansion of the flaps 10, 10<SP>1</SP>. In a modification, the pinions may be replaced by cam follower arms engaged in cam slots of a cam plate mounted on the bar 18. In a further modification, the expansible former comprises two pairs of fingers, each finger being mounted on a shaft and the shafts of each pair being rotated in opposite directions to collapse or expand the former.

Title: Aromatic polyester compositions
IPC: C08K5/06
Filed: 1956-01-30
Abstract: The invention comprises a composition of a high molecular weight linear aromatic polyester plasticised with a bis-aralkyl ether.  The term "high molecular weight polyester" is used to denote a polyester having an intrinsic viscosity of at least 0.4 when measured at 30 DEG C. in a solvent composed of a 60/40 mixture by weight of phenol and tetrachloroethane.  The plasticiser can be incorporated while the polymer is in solution or by using an internal mixer or a two-roll mill.  An example describes mixing an ethylene terephthalate-ethylene isophthalate with bis-(bimethylbenzyl) ether.  The plasticisers can also contain chloro, bromo, nitro, hydroxy, aryl, aryloxy, alkyl and alkoxy groups.  Specified are bis-benzyl, bis-(diethylbenzyl), bis-(p-phenylbenzyl), bis-(p-phenoxybenzyl), bis - (chlorobenzyl), bis - (nitrobenzyl), bis - (hydroxybenzyl) and bis - (b  - phenylethyl) ethers.  The polyesters can be those produced by self-condensation of hydroxy-acids such as p-(b -hydroxyethoxy benzoic acid, p-(hydroxymethyl) benzoic acid and p-(b -hydroxyethyl) benzoic acid.  Other examples are polyesters and copolyesters of acids such as terephthalic, isophthalic, 1,4-diphenoxy benzene-41,411-dicarboxylic, 1,4 - bis - (phenoxymethyl) - benzene - 41,411 - dicarboxylic (phenoxymethyl) - benzene-41,411 - dicarboxylic, phenoxybenzene - 41,411-dicarboxylic and diphenoxy alkane dicarboxylic acids with dihydroxy compounds such as glycols or hydroquinone.
