Filed: 1927-02-01
Abstract: 291,823. Petroff, G. Feb. 1, 1927. Mineral oils, purifying-Mineral oils and naphtha are treated in presence of fatty acids such as stearic and oleic acids with a sulphonating agent such as concentrated or fuming sulphuric acid, sulphuric anhydride, or chlorosulphonic acid. In an example, petroleum oil which has been treated with 5 per cent of the monohydrate, is mixed with 5 per cent of oleic acid and 20 per cent of sulphuric acid of specific gravity 1.85 is gradually added. Tarry matter separates out and is heated with water to remove the sulphonic acids. The treated oil is washed with alkali. In another example petroleum is mixed with 15 per cent of stearic acid and treated with 50 per cent of fuming sulphuric acid or with sulphur trioxide or bath. The product is washed with alkalies, and is free from unpleasant smell. The term mineral oil is used to include all oils containing hydrocarbons obtained from peat, lignite or coal tar, or synthetically.

Title: Cable Winch Assembly
Inventor: KOENIG THEODORE J
IPC: B66D1/22
Filed: 1968-01-19
Abstract: 1,148,995. Constant tension winches. THEODORE J. KOENIG. 19 Jan., 1968 [25 Oct., 1967], No. 3109/68. Heading B8B. The drive for the drum shaft 45 of a constant tension winch comprises an electric motor shaft carrying a sun gear, a carrier freely rotatable on the shaft and carrying planet gears engageable with the sun gear and an internal ring gear, and a reduction gear drive 42, 44 (part only shown between the carrier and the shaft 45, the ring gear and motor shaft which are clutchable to each other being each provided with a brake. The clutch and ring gear brake are jointly electrically operable to give either a low speed or a straight through drive to the reduction gear 42, 44, the low speed drive being normally in operation. A winching drum 52 is freely rotatably mounted on the drum shaft 45 and is drivably connected therewith through a compression spring 60 connecting an ear 58 on one flange 55 of the drum with an ear 57 on a flanged hub 50 keyed to the drum shaft 45. With this arrangement, the compression of the spring 60, i.e. the relative rotation between the drum 52 and the shaft 45, is a measure of the tension T in a cable 62 wound on the drum. This relative rotation is translated into axial movement of a sleeve 68 freely mounted on the shaft 45 and having a projection 70 which is connected via pivoted links 72, 74 to the drum at 78 and to a projection 66 keyed to the shaft 45. The axial movement of the sleeve 68 is transmitted through a linkage system to control the electric drive motor whereby a substantially constant tension in the cable 62 is automatically maintained. If after a fixed time the cable tension has not reached a pre-determined value, the drive motor torque is increased automatically at intervals until either the tension is reached or the motor cuts out and the brakes are applied to lock the system. If during cable pay-out, the motor voltage is increased to a pre-determined level due to rapid over-riding of the system by the cable, a voltage sensing relay operates to energize the ring gear brake and clutch, producing the straight-through drive to the motor whereby its speed is reduced.

Filed: 1945-02-15
Abstract: 596,312. Gear-cutting. RICKENMANN, A. Feb. 15, 1945, No. 3781.. [Class 83 (iii)] [Also in Group XXIII] A method of grinding toothed gears by means of a helical-profile rotary grinding-tool of the hob type comprises a first phase in which the workpiece to be ground derives its rotational drive from the said grinding tool and a second phase in which the workpiece is positively driven in a predetermined ratio to the speed of rotation of said grinding-tool. The grinder 4, which is of the form shown in Fig. 6, and its driving motor 6 are mounted on slide 3 movable, by hand wheel 41, on slide 2, movable, by hand wheel 31, on the frame 1. The grinder shaft 5 drives through bevel gears 9, 10, shaft 11, gears 14, 15, 16, 17, shaft 18, bevel gears 19, 20, shaft 21 and gears 22, 24 a work spindle 25, Fig. 5, between which and the arbor 26 on which a number of gear-wheel blanks 38 are mounted is provided a clutch 30 comprising pistons 67 pressed inwardly by springs 69 and projected outwardly into driving position by fluid supplied by a gear pump 46 under control of valve 61 through pipe 601, distributer groove 652 and bores 251, 252, 253 ; a pressure maintaining valve 62 and pressure gauge 63 are provided. Rotation of the work spindle 25 is controlled by gear pump 85 driven therefrom by gears 24, 77, 79, 80 and having pressure adjusting valve 86 and gauge 88. The pump 46 supplying fluid to operate the clutch also supplies fluid through connection 602 to a cylinder 71, Fig. 1, to operate member 73 to lock slide 3 to slide 2 whenever the clutch 30 between the work spindle and arbor is rendered operative. The arbor 26 is mounted between lower centre 27 on the work spindle 25 and upper centre 28 on tailstock 29, the whole assembly being carried by a slide 23 vertically reciprocable, so as to carry the blanks axially past the grinder, by piston 57 in cylinder 53 supplied with fluid, from gear pump 45, driven in common with the pump 46, under control of a valve 52 operated manually by handle 56 or with automatic reversal. In operation, the clutch 30 is left inoperative until the workpiece has attained its full speed and the backlash of the various gearing members has been taken up ; the clutch is then rendered operative. In a modification, instead of the drive for the work being taken off the grinder shaft, the grinder and work are independently driven by two synchronous motors having damped starting torque and asynchronous driving characteristics. The grinder motor may drive a generator supplying the work motor. The gearing in the work drive may include gears having a prime number of teeth.

Abstract: 795,484. Delivering liquid fuels. MULLER, J. Feb. 8, 1956 [June 9, 1955], No. 3934/56. Class 116 [Also in Group XXVII] A swing-arm for delivering fuel includes ,a telescopic arm 2, 8 (Fig. 1) mounted for universal movement at the upper end of a delivery column 1 and provided with means which hold it in any position to which it is moved. In the construction of Fig. 1 the telescopic arm 2, 8 forms the delivery conduit for the fuel and terminates in a depending pipe 3. The arm 2, 8 is counterbalanced by compression springs 23 connected between brackets 18 on the swinging arm and brackets 19 on a head 4 rotatable at the top of the column 1. The arm 2 is connected to a T-fork 5 (Fig. 2), extending from the head 4, by a pair of pipes 6 which lead to couplings (see Group XXVIII) at the ends of the fork 5 permitting vertical swinging of the arm Each coupling includes a friction lock in which a pair of rollers 47, 48 (Fig. 4) are normally pressed by springs 51, 52 to jam in wedge-shaped recesses 45, 46 formed between a movable ring 44 and a fixed ring 28. Projections 53, 54 from the swing- ing arm serve however to unwedge the rollers 47, 48 provided the force exerted on the swinging arm is sufficient to overcome the spring 51, 52. The outer portion 8 of the swing-arm may be telescoped within or without the inner portion 2 by a connection 59 (Fig. 5) to an endless chain 58 supported by sprockets from the portion 2 of the arm and driven by a crank 60 through an irreversible coupling similar to that illustrated in Fig. 4. Where the portion 8 telescopes over the portion 2 as in Fig. 5 the tail sprocket is carried by a member 56 sliding on the portion 8 and connected by a link 57 to a bracket 55 on the portion 2. The drop-pipe 3 is connected by a rotary joint 10 to an elbow 9 on the swing-arm. Handles 11, 12 assist in manipulating the arm and a valve 13 controlling the flow and biased by a spring 16 is controlled through a link 14 from a handle 15. In an alternative construction (Figs. 6 to 9, not shown) the telescoping swing-arm serves to support a flexible conduit which runs on rollers in the inner portion 2 (Fig. 1) of the swing-arm and passes over an arcuate guide at the head of the outer portion 8 of the arm to depend freely. In this construction a jack operated through an irreversible drive alters the inclination of the swing-arm which is carried by a slewing column. The flexible hose may pass to the swing-arm directly from a drum in the dispensing apparatus and may be guided by a suitable fairlead at the inner end of the swing-arm.
