Abstract: 1,218,009. Synthetic filament webs. FARBENFABRIKEN BAYER A.G. 23 June, 1969 [22 June, 1968], No. 31594/69. Heading D1R. A non-woven matted web 16 is produced by drawing off a set of synthetic filaments 3 from spinnerets 2 or the like by means of a gas jet 8 and depositing them on a support 15. The gas jet 8 emerges from a slot nozzle 6 in a wall 5 inclined at an angle of 50-75‹ to the wall from pressure chamber 7 at a supersonic flow velocity and is deflected about the sharp edge 9 to flow down along the face of wall 5. The set of synthetic filaments 3 enter the jet 8 in the region where it is deflected. A secondary gas flow may be provided by arranging a plate 13 opposite the wall 5 so that the outer filaments are drawn in towards the centre of the set. A spacer 10 may be used to align the filaments so that they enter the jet 8 in the centre plane thereof and may be in the form of a tensioned wire or an endless rotating wire. The filaments 3 are carried along by the jet 8 and deposited on the support 15.

Abstract: 1,149,285. Endless conveyers. KLIKLOK CORP. 11 July, 1967 [12 July, 1966], No. 31808/67. Heading B8A. Boxes D0, D1 &c. are fed on to a belt conveyer 12, 13, by a shoot 11 (Fig. 9) and successively move up into engagement with pushers 18, 19, carried respectively by chains 23, 26, of timing conveyers which run at a slower speed than that of the conveyer belts 12, 13. The arrangement is similar to that described in Specification 831,588 in which the leading edge of a box is engaged by a pusher 18 (or 19) as shown in Fig. 1, and subsequently the side of the carton is engaged by the pusher 19 (or 18 as the case may be) the latter pushing the carton laterally against an endless guiding belt 14 associated with the timing conveyer 23. Only two of the pushers 18 (or 19) and one of the pushers 19 (or 18) are exposed within the conveying track of the timing conveyers 23, 26, at any one time. The endless belt 14 and the corresponding supporting belt 15 on the other side of the conveying track moves at a speed which is slower than that of the belt 12, 13, but faster than that of the pushers 18, 19. The belt 14 and the timing chain 23 are carried on a plate 38 which has a parallel linkage mounting with respect to the main conveyer frame. This enables the belt 14 and the timing conveyer on each side of the conveying track to be moved laterally to accommodate boxes of different widths for maintaining the conveying lines of these conveyers parallel with the conveying track. One arm of the parallel linkage is formed by a link 54 (Fig. 10), the other is formed in effect by the fixed distance between the axis of a driving sprocket 42 of a drive-chain 43 of these conveyers, and the axis 51 of a drive sprocket 49 connected to a gear-box 59 (Fig. 10). After leaving the timing conveyers the boxes are successively engaged by projections 29 of an outfeed conveyer 28.

Title: Improvements relating to fluid-pressure-operated braking mechanisms for trailer vehicles
Inventor: BALLARD DONALD HENRY
IPC: B60T8/18
Filed: 1957-10-14
Abstract: 889,804. Fluid-pressure brakes. CLAYTON DEWANDRE CO. Ltd. Sept. 29, 1958 [Oct. 14, 1957], No. 32043/57. Class 103 (1). A fluid pressure-operated braking mechanism for a trailer vehicle,and of the kind in which the maximum pressure attainable in the brake actuating means is dependent upon the vehicle load, comprises a control valve 1 in a compressed-air, or vacuum, line 3 to the brakeactuating means 4, the valve 1 including a movable valve element 13 coacting with a valve seat 14 to control the fluid flow through said line 3 and spring-urged away from the seating, and pressure-responsive means sub. jected to the pressure in line 3 and acting against the spring 20 to close the valve, the spring 20 acting between the valve element 13 and a member 18 which is movable with a sprung part of the vehicle relatively to an unsprung part. The valve 1 is mounted on the platform 2 of the trailer vehicle, and a roller 19 on the tubular thrust member 18 is lifted by a lever 22 pivoted to a rod 24 in turn hinged to a member 25 fixed to the wheel axle. A diaphragm 7 and the element 13 are attached to a rod 15 and collar 21 which are thrust upwards by a coil spring 20. If the trailer is unladen, the distance from wheel axle to platform 2 is the maximum, shown in Fig. 1; member 18 projects the maximum and spring 20 has minimum compression. When the tractor servo is operated, vacuum is supplied to cylinders 4 through line 3 and passages 9, 10, 11 and 12 of valve 13, 14, and lower part 6b of the diaphragm chamber, to apply the brakes. This vacuum will also act on the underside of diaphragm 7, and when the pressure differential so created over the diaphragm overcomes the loading of the spring 20 the element 13 moves down on to seat 14 to interrupt the vacuum to the trailer brake cylinders 4 and limit the degree of braking. Since the trailer is unloaded the compression of spring 20 is relatively light and the degree of permissible braking is correspondingly limited. Loading of the vehicle lowers the platform 2, and the lever 22 is rocked clockwise about its pivot on the bracket 23, whereby member 18 is moved upwards in tube 17 to compress spring 20. Hence, a higher degree of vacuum is needed to overcome the spring loading on the diaphragm, giving a correspondingly increased degree of braking.

Title: Process for recovery of complex ester synthetic lubricants
IPC: C07C69/34
Filed: 1954-11-05
Abstract: Complex esters, obtained by reacting an aliphatic dicarboxylic acid, an aliphatic monohydric alcohol and a glycol or a polyalkylene glycol so that the resulting complex esters do not contain free carboxyl or hydroxyl groups, are contacted with alumina to remove corrosive material and any complex esters adsorbed on the alumina are extracted with a paraffin containing from 6 to 16 carbon atoms and recovered by distilling the paraffin extract.  Suitable paraffins are hexane, heptane, octane, nonane, and decane, and mixtures thereof particularly mixtures of paraffins containing from 11 to 14 carbon atoms.  The treatment with the alumina and with the paraffin may be carried out at room temperature up to 150 DEG  F. and/or for a period of 1/2 to 3 hours.  A suitable proportion of paraffin is 1 to 3 volumes (preferably 1 volume) of paraffin for 1 volume of alumina from the above contacting step.  A suitable quantity of alumina is 0.1 to 7.0 per cent by weight of the complex ester.  In the example a complex ester obtained by reacting together 2 mols. of sebacic acid, 2 mols. of 2-ethylhexanol and 1 mol. of polyethylene glycol having a molecular weight of about 200, using toluene as the water entrainer and sodium bisulphate as the catalyst, is treated by the above process rising hexane and heptane, and mixtures of paraffins having 11 to 14 carbon atom for the extraction step.  The use of acetone and isopropyl alcohol for the alumina extraction step is also referred to.
