Title: Process for winding parallel wire strand
IPC: B65H55/00
Filed: 1974-01-29
Abstract: 1463319 Winding and unwinding parallel wire strands ARBED-F & G DRAHTWERKE KOLN GmbH and WESTFAELISCHE UNION AG 29 Jan 1974 4193/74 Heading D1T A method of winding parallel wire strand onto one or two drums and subsequently unwinding the strand comprises, without the application of torsional forces, allowing or causing individual wires of the parallel wire strand to be mutually displaced in one or more directions so as substantially to eliminate the tension differences which tend to result between the individual wires when the strand is wound onto a drum; and wherein the strand is unwound so that the individual wires are returned to their original positions in the strand and the parallel wire strand is restored to its original form. In Fig. 3 a strand or parallel wires passes between rollers 9, 10; over vibrating means 8; through a spreading plate 7 that causes the wires to be arranged in a flat parallel array and these parallel wires are then wound onto a drum 1. If the span of the spread layer is too wide for the drum 1 the spread wires may be arranged to lie in more than one layer. The tail end of the strand may be held in its desired configuration by an anchoring sleeve whereby, during unwinding of the strand, the individual wires tend to come together to give the strand its original shape and form. The strand may be unwound by passing it through one or more shaping nozzles or dies so that the wires coming off the drum are reassembled by the nozzles or dies to give the original bunched configuration of the wires in the strand.  In Fig. 5 the bundle of parallel wires 14 is wound up from both ends by means of two drums 11 in such a manner that the outer wires of the bundle on one drum are the inner wires of the bundle on the other drum, the drums being rotated in the same direction. This compensates for any tension differences that would otherwise occur between individual wires when the bundle of wires is wound up. In the above embodiments the strand may be enclosed in a protective flexible sheathing before being wound up, the bare wires being covered with a lubricant to which may be added a passivating media such as zinc chromate or lead oxide.

Title: Improvements in or relating to the manufacture of amine salts of o-substituted dinitrophenols
Filed: 1945-02-20
Abstract: Compositions suitable for use as insecticides on dilution with water are obtained by reacting an aqueous suspension of 2.4-dinitro-o-cyclohexyl phenol in a ball mill with dicyclohexylamine in substantially equimolecular proportions. Advantageously, the aqueous suspension of the dinitrophenol is prepared by grinding it with water and a suspending agent, i.e. an agent which permits the formation of a fluid non-flocculent suspension of the dinitrophenol when so ground.  Specified agents are: water-soluble colloids, sulphite cellulose waste liquors, sulphonated naphthalene-formaldehyde condensation products and gelatine. Sedimentation of the suspension may be inhibited by the addition of a small proportion (e.g. 0.01 to 1 per cent) of a thickening or stabilizing agent such as a water-soluble cellulose ether, starch or colloidal clay.  Wetting or spreading agents may also be included to increase the spreading or penetrating properties of the suspension when diluted for spraying.  In an example, an aqueous suspension of 2 : 4-dinitro-o-cyclohexyl phenol is prepared by grinding the mixture in a ball mill, grinding the resulting suspension with dicyclohexylamine and further grinding it with a little "Cellofas W.L.D." (Registered Trade Mark) to obtain a fluid paste of the dicyclohexylamine salt of 2 : 4-dinitro-o-cyclohexylphenol which may be diluted with water to form an insecticide spray.  Specification 546,018 is referred to.ALSO:Compositions suitable for use as insecticides on dilution with water are obtained by reacting an aqueous suspension of 2.4-dinitro-o-cyclohexyl phenol in a ball mill with dicyclohexylamine in substantially equimolecular proportions.

Abstract: 1347663 Adjustable seat mechanisms FRITZ KEIPER 31 Jan 1972 [24 Feb 1971] 4449/72 Heading A4J [Also in Division E2] A hinge fitting for the adjustable backrest of a seat comprises a fixed hinge member 16 to be secured to the seat, a pivotable hinge member 15 to be secured to the backrest and locking means provided there between; the locking means comprising two toothed portions 18, 19 each combined with one of the hinge members, one toothed portion 19 being displaceable and adapted to be optionally engaged or disengaged from the other toothed portion 18 by an operating device actuable by means of a handle 39, the operating device comprising a first element 22 for bringing the displaceable toothed portion 19 into a locking position and a second element 23 for bringing it into a releasing position, the operating elements being pivotably mounted on respective spaced apart pivot pins 17, 26 and being coupled to each other by a lever arrangement. The toothed portion 19 travels between guides 20 and 21, and is displaced into meshed engagement with portion 18 for the locking position by a cammed track 31 of the element 22. The portion 19 is displaced out of mesh for the releasing position by a cammed track 32 of the element 23 which engages a projection 34 on the portion 19. The linking arrangement of the two operating elements 22 and 23 includes a lost-motion device and is such that when the element 22 engages the portion 19 for the locking position, the element 23 simultaneously disengages the projection 34, and when the element 23 moves towards the releasing position a certain amount of material play occurs before the element 22 follows the motion of the element 23. A spring 43 biases the elements 22, 23 into the locking position. The element 23 is fixed to a rotatable pin 26 which is provided with a prismatic cavity (30), Fig. 3 (not shown), into which is inserted a connecting bar (29), Fig. 1 (not shown), so that it rotates with the pin 26 and acts as a link with a corresponding pin of a hinge fitting (14) arranged on the opposite side of the seat.

Filed: 1974-01-31
Abstract: 1454434 Microwave heating CHEMETRON CORP 31 Jan 1974 04595/74 Heading H5H To prevent heating of certain items of food on a tray 300, a conductive shield 200 impervious to microwaves and mounted in a microwave oven is moved into a shielding position from an open position (Fig. 4) when the food tray 300 is inserted. The shield 200 has a pair of rearwardly extending fingers which engage in sockets 102, 104 in the rear wall of the oven cavity and a bracket 208 which secures the shield to a tongue 106 mounted on a rotary shaft 416. A spring blade 206 depends from the shield 200. The lower edges 212 of the shield 200 are coated with P.T.F.E. tape to prevent arcing between the shield and the conductive flanges 310, 318 on the tray 300. The shield 200 is biased upwardly by a spring 414 acting on a lever 412 mounted on shaft 416. When a tray 300 is inserted in the oven its leading edge 320 engages the blade 206 of shield 200 and rotates it to the closed position where it forms a microwave seal with the flanges 310, 318 against the biase of spring 412. When the oven door 112 is closed, chain 408 connecting a door hook 402 to a pivoted crank 406 goes slack allowing the crank to be rotated clockwise by a spring 420 and this causing a spring 410 attached to the crank 406 and lever 412 to firmly seat the shield 200 on the tray 300. Providing the shield is properly seated and the door H2 is closed, switches 418 and 422 actuated by lever 412 and crank 406 respectively initiate the heating operation. If the shield is improperly seated switch 418 is not actuated and switch 422 gives an audible alarm. The oven construction, and its control of heating is the same as in copending application 4475/74.

The ethers may be methyl vinyl ether, ethyl vinyl ether, propyl vinyl ether, isopropyl vinyl ether, normal butyl vinyl ether, isobutyl ether, and 2-ethyl hexyl vinyl ether.  A solvent or diluent such as pentane, hexane, benzene, dichloromethane, chlorobenzene, diethyl ether, dibutyl ether, ethyl acetate, amyl acetate, acetone, methyl ethyl hetone and acetomitrile may be added to the polymerization mix.  The polymer may be precipitated with methanol containing a small amount of phenyl beta naphthylamine and the polymer washed and dried.  A stretched sample gave X-ray evidence of stereo regular chain segments.  Polymerzation may be affected at a temperature of 0-120 DEG C.ALSO:A hydrate of ferric hydrosulphate having the composition Fe2(SO4)3.H2SO4.XH2O where X is a number not less than 3 nor more than 4 is obtained by heating Fe2(SO4)3.6H2O in strong H2SO4 at 80 DEG C. for 4 1/2 hours and then cooling and treating with diethyl ether.  A white powder is obtained which after washing with ether and drying in vacuo contains 19.85% of Fe and 22.7% of S.
