Patent GB-217763-A (GB)
Abstract: 217,763. Ingold, E. A. June 13, 1923. Twisting wires together.-In an apparatus for twisting together the overlapping ends of a loop of wire encircling a wooden or other box, bale &c., one end of the wire is gripped by a pivoted clip co-operating with a transversely slidable clip, which is normally fixed but which is capable of sliding outwardly on withdrawal of a stop so as to permit the wire and pivoted clip to be drawn forwards towards the twisting-pinion as the wire shortens during twisting so as to avoid breakages. One end B of the wire is fixed in a gripper C longitudinally movable to tension the wire as described in Specification 202,335, and the other end A is secured between a lever E, preferably with an eccentric-serrated end, and a clip D, which is adjustably fixed to suit the diameter of wire by screws and slots on a slide F, normally fixed in its forward position by a lever H held in position by a bar I pivoted thereto and resting on a positioning stop J and engaging an adjustable arresting stop L. At a pretedermined point of the twisting operation a cam K<1> on one of the shafts K of the twisting pinion or pinions raises the bar I against the action of a spring I<2> so as to release the lever H, whereupon the wire and lever E are drawn forwards by the tension of the wire into the position shown in Fig. 5, the slide F being pressed forward by a spring F'. When the cam K<1> engages a notch I<1> in the bar I the lift of the bar ceases, and the bar is restored to its normal position when the lever E is displaced manually or automatically to release the cut-off, end of the wire. The lever E may be adjustable to suit wires of different diameter instead of the clip D.

Title: Splitting up of hydroperoxides of aromatic hydrocarbons by means of an acid catalyst
Filed: 1954-07-26
Abstract: Phenols and aldehydes or ketones are formed by the cleavage of aromatic hydroperoxides by passing a gas containing 1-5 per cent by volume of hydrogen chloride through a solution of the hydroperoxide in a hydrocarbon.  The solution may be of the hydroperoxide in its parent hydrocarbon prepared by partial oxidation of that hydrocarbon. Hydroperoxides specified are those of isopropyl benzene, p-methyl isopropyl benzene, ethyl benzene, diphenyl methane, 1:1 diphenyl ethane, di-p-tolyl methane, 1:1 di-p-tolyl ethane, and cyclohexyl benzene, which are converted according to the process of the invention to phenols, such as phenol or p-cresol, and aldehydes such as acetaldehyde, benzaldehyde or p-tolualdehyde, or ketones such as acetone, acetophenone, p-methyl-acetophenone or cyclohexanone.  The gas catalyst, consisting of an inert gas such as air, carbon dioxide or nitrogen containing hydrogen chloride, is passed continuously or intermittently through the stirred solution of the hydroperoxide maintained at below 50 DEG  C.  The catalyst may be recycled.  On completion of the reaction, the gas catalyst may be removed by passing the inert gas alone through the reaction mixture which may then be neutralized with dry ammonia gas, alkali metal hydroxides, soda, calcium oxide, or calcium carbonate, and the products isolated by distillation, or the phenols may be extracted with an alkali metal hydroxide solution. In an example, air containing hydrogen chloride is passed through a stirred solution of 1:1 di-p-tolyl ethane hydroperoxide in 1:1 di-p-tolyl ethane with cooling to form p-cresol and p-methyl acetophenone.  Other examples include the cleavage of cumene hydroperoxide under similar conditions to form phenol and acetone and the cleavage of di-tolyl methane with hydrogen chloride in nitrogen to form cresols and tolualdehydes.

Abstract: 1,119,427. Peeling potatoes. INSTITUUT VOOR BEWARING EN VERWERKING VAN LANDBOUWPRODUKTEN. 16 May, 1967 [25 May, 1966], No. 22749/67. Heading A4C. A method for peeling potatoes or similar tubers comprises moving the same against a series of rollers fitted with bristles which rotate about their own axes, these rollers forming a rotary cylindrical drum kept horizontal or slightly inclined, while feeding little or no water to the drum. On the outside of the rollers the sum of the centrifugal accelerating forces caused by rotation of the drum and rollers is large enough to cause the previously softened peels to move outwards from the drum while on the inside the difference between the two said forces is small enough to hold the peel on the rollers. A suitable apparatus consists of a rotary drum 1 which rotates as a whole on wheels 7 by means of a driving unit. Rollers 2 fitted with bristles 3 are driven via a geared system, the whole drum being fitted inside a fixed housing 11. Scrapers 12 fastened between the plates supporting the rollers rotate with the drum and scrape the inner surface of housing 11 free of peel, which is removed via opening 13. The acceleration needed to hurl the peel off rollers 2 on to housing 11 may be lowered by the addition of dry finely-divided material into the drum.

Title: Improvements in gyro integrators
IPC: G01F1/76
Filed: 1961-06-23
Abstract: 953,585. Gyroscopic apparatus; flowmeters. GENERAL ELECTRIC CO. June 23,1961 [July 20, 1960], No. 22748/61. Headings G1C and G1R. In a gyroscopic integrating device, for example for obtaining an integrated output from a mass flowmeter, in which a gyro rotor 19, Fig. 1, is universally mounted for movement about major and minor axes CC, BB, torque being applied about axis BB to cause precession about the axis CC and thus drive a counter 26 through gearing 27, the effect of friction in the linkage connecting the flowmeter to the gyroscope is counteracted by applying periodic reversing torques about the major axis CC during precession about that axis, to cause oscillation of the gyroscope about the minor axis BB and thus oscillation of the linkage. The reversing torques may be applied by the rotor levelling arrangement. As shewn, the fluid flowing through a conduit 14 passes through an impeller 16 driven at constant speed by a synchronous motor energized from the same source of alternating current as the motor of rotor 19. The angular momentum thus imparted to the fluid is removed by a turbine 17 whose shaft 25 transmits a torque through linkage to the gyroscope. The linkage comprises a crank arm 31, on shaft 25, engaging crank arm 31, on shaft 25, engaging crank arm 32 on shaft 33, mounted within the streamlined bracket 34. Motion is transmitted outside the flowmeter housing by magnets 37, 38 rigid with shaft 33, co-operating with magnet 39 on one end of a shaft 40, the other end carrying a crank arm 45 engaging push rod 46 which extends upwardly through the hollow lower trunnion 24 along axis CC. The upper end of rod 46 bears on an L-shaped lever 47 which is pivoted on outer gimbal 21 and engages at 49 an arm 51 on inner gimbal 20 so as to produce torque about axis BB and thus precession about axis CC. To level the gyro, the rotor 19 has a shaft extension carrying a disc 53 with projecting magnets 54. These co-operate with aluminium rings 55, 56 on the gyro casing and by means of eddy currents cause the rotor axis to lie in a plane at right angles to the axis of rings 55, 56. If this axis coincides with axis CC the rotor axis is horizontal and by providing the inner gimbal 20 and casing with co-operating bar magnets (Fig. 6, not shown) a torque is produced about axis CC and thus oscillation of the gyro about axis BB as it precesses around axis CC. However, if the axis D, Fig. 3, of rings 55, 56 is slightly displaced from axis CC, the rotor axis, in aligning itself in a plane at right angles to axis D, will cause the gyro to oscillate about axis BB as it precesses about axis CC.
