Title: A new woolly fabric and method of making the same

Abstract: 1,040,563. Tufting machines, tufted fabrics. H. PRESTON. Nov. 16, 1962 [Oct. 9, 1961], No. 36200/61. Headings D1G and D1K. A method of making woolly fabric consists in pulling individual tufts of wool through a base fabric, either by taking the tufts from a fleece which is fed towards the fabric, or by taking the tufts from a sheepskin which is fed towards a cutting mechanism located adjacent the fabric and arranged to sever the tufts from the skin as or immediately before the tufts are pulled through the fabric, the fabric being subsequently treated on its reverse side with an adhesive to secure the tufts thereto. As shown, a row of horizontal needles 1 is fixed in a bar 3, slidably mounted on a bed 2 and reciprocated by means of connecting rods 4 and crank discs 5. Each needle has a fixed jaw 11 and a pivoted jaw 12 having an extension 14 biased by a spring 15 to close jaw 12. Extension 14 is formed with a triangular protuberance 16, which, during rearward movement of the needle, abuts a collar 17 loosely mounted on the needle until collar 17 is halted by a bar 18. Protuberance 16 then passes through collar 17, whereby jaw 12 opens and closes. Near the end of the forward movement of the needle, collar 17 is halted by a bar 19, whereby the protuberance passes through the collar to cause opening and closing of jaw 12. A vertical web 6 of base fabrics is fed intermittently past the needles. A sheep's skin 8 is fed intermittently horizontally on a conveyer towards the needles. The needles in their forward movement pass through the stationary web 6 and seize tufts of wool on the stationary skin 8. The needles and skin are then moved at the same speed, whereby the seized tufts are severed by a stationary blade 9, the movement of the skin being halted when the tips of the needles reach the cutting edge of blade 9. The tufts are then partly pulled through the web 6, when the jaws 12 open to leave the tufts engaged in the web. Blade 9 is omitted if a fleece, instead of a skin, is fed by the conveyer.

Title: Process for the production of High-Pure Aromatic Hydrocarbons from Cracked Gasoline
IPC: C10G59/02
Filed: 1966-08-16
Abstract: 1,155,416. Aromatic hydrocarbons. YAWATA CHEMICAL INDUSTRY CO. Ltd. 16 Aug., 1966 [16 Aug., 1965; 23 Aug., 1965], No. 36537/66. Heading C5E. High-purity aromatic hydrocarbons are obtained by subjecting a feed oil comprising cracked gasoline or cracked gasoline blended oil to aromatization refining by contacting said feed oil with at least one catalyst comprising a platinum group metal or an oxide of chromium, molybdenum or tungsten in the presence of hydrogen in an amount of 2-15 mols/mol of hydrocarbon in the feed oil, at a temperature of 545-595‹ C., at a partial hydrogen pressure of 5-25 kg./sq. cm. gauge, and at a LHSV of 0À2-4 hr.-<SP>1</SP>, and distilling the refined oil to separate individual aromatics therefrom. The refined oil contains no non-aromatics difficult to remove by distillation, and contains more aromatics, than did the feed oil. Reactions occurring during the refining include dehydrogenation, dehydrogenation/isomerization, and dehydrocyclization to form aromatics, and hydrocracking of paraffins, olefins and impurities. The refining may be carried out in a fixed bed, fluidized bed or moving bed reactor, and in one or more stages. In a multi-stage process the catalyst in the various stages may be the same or different, a preferred arrangement being a first stage with a platinum group catalyst and a second stage with an oxide of Cr, Mo or W as catalyst. The feed oil may be cracked gasoline, e.g. from an olefin production plant, or a mixture thereof with coke-oven light oil, oil-gas light oil, naphtha, shale oil naphtha or reformed gasoline. Prior to the aromatization refining the feed oil may be subjected to one or more of the following treatments: prefractionation to separate C 6 , C 6-7  or C 6-8  fractions as desired; primary hydrogenation to remove dienes; secondary hydrogenation to remove sulphur and nitrogen compounds, and conventional catalytic reforming. Similarly, after the aromatization refining and prior to the final distillation, the refined oil may be subjected to a de-alkylation process to increase the benzene production, and to a clay treatment. Suitable conditions and catalysts, where appropriate, are given for these optional treatments. The final distillation may be a simple rectification, an azeotropic distillation, or an extractive distillation. In examples, the main products are benzene and toluene, with smaller amounts of ethyl benzene and xylenes.

Title: Wheel slip sensing arrangements
IPC: B60T8/172
Filed: 1970-07-30
Abstract: 1312833 Sensing wheel slip electrically ROBERT BOSCH GmbH 30 July 1970 [31 July 1969] 36861/70 Heading G1N [Also in Division F2] In a wheel slip sensing arrangement a pulse train the pulse frequency of which is dependent upon the angular velocity of the wheel is applied to a monostable trigger circuit via a pulse shaper and the output of the trigger circuit is connected via a differentiating circuit to a hysteresis circuit. The output 118 from a pulse or A.C. generator 18 of the variable reluctance type, electro-magnetic, fluidic or light generator coupled to the vehicle axle of each wheel is squared by Schmitt trigger 34 and then differentiated by circuit 35 to produce a train of sharp pulses 135 which trigger a monostable circuit 36. The output 236 from circuit 36 is averaged, 261, by low pass filter 37 and fed to differentiating circuit 61, Fig.6 (not shown). During unbraked periods the output from the low pass filter 37 is constant as shown on the left hand side of curve 261 of Fig. 3 and the circuit controlling the activation of the brakes, Fig. 1 (not shown), is unenergized. As the wheel is accelerated or decelerated the magnitude of the output voltage of the low-pass filter 37 increases or decreased and a signal is produced at the output of stage 61 proportional to the rate of change of the output voltage of the low pass filter 37. If the vehicle wheel decelerates very rapidly i.e. begins to slide the amplified output voltage 261 of a stage 61 falls below the lower level, -b, of hysteresis circuit 42, the latter switches and triggers monostable circuit 43 having a natural relaxation period of 200m. s. The output of circuit 43 acts on a solenoid valve by way of gate 44 and amplifier 47 to reduce the pressure in the braking system and release the brakes. When the wheel is subsequently accelerated again the frequency of pulses 135 increases and the output voltage 261 of stage 61 increased so that the upper threshold of hysteresis circuit 42 is exceeded which then switches off prematurely the output 143 from monostable circuit 43 thus resulting in the brakes being applied again. If the sliding wheel should not be accelerated sufficiently e.g. on a very smooth road, the interval between pulses 136 is also not reduced again and the output of stage 61 does not increase sufficiently to trigger the hysteresis circuit and in this case monostable circuit 43 terminates automatically after 200 m.s. and the brakes are applied again momentarily. In order to prevent the circuit being activated at very low speeds AND circuit 44 is included input 45 of which is supplied with a signal from a gate circuit common to all the wheels Fig. 4 (not shown) only when the peripheral speed of all the wheels is above a speed of 7 Km/h, this gate circuit being supplied with the signals at terminals 48 from filler circuits 37 of all the wheels.
