Title: Solids flow equalizer-blender
IPC: B65G47/72
Filed: 1964-10-28
Abstract: 1,020,650. Blending solids. E. I. DU PONT DE NEMOURS & CO. Oct. 28, 1964 [Nov. 1, 1963], No. 43969/64. Heading B1C. Apparatus for equalizing the flow rates of streams of polyethylene granules and blending them comprises a vessel 11 having an inverted conical lower portion 11b and a coaxial conical baffle 20, the materials being supplied through a plurality of conduits 10 all of the same diameter and arranged symmetrically about and equidistant from the axis of the vessel and discharging into its top or upper part at the same horizontal level. There is an axial bottom discharge outlet 18. The conduits 10 must be straight for a distance at least three times their diameter and inclined to the horizontal at an angle greater than that of the angle of repose of the materials to be processed. The baffle 20 must be positioned so that the distance x is greater than the self-bridging distance of the materials and not more than half the radius of the baffle base, and so that the area of the annular opening between the baffle and the vessel is greater than that of the discharge opening but less than the sum of the crosssections of the inlet pipes. The baffle must also be positioned so that its base is not less than three inlet pipe diameters below their discharge ends and not less than 3x above the vessel discharge outlet. When the apparatus is "flooded" with material equal amounts of each stream will flow through it irrespective of the heads in the inlet pipes. The maximum rate of flow is achieved when the centres of the pipes 10 are in line with the centre line of the annular interspace between the baffle and the vessel. The baffle may be vertically adjustable as shown; it may have a notched or scalloped edge, and the inlet pipes may be vertical, see Fig. 3 (not shown). The materials may be recirculated.

Title: Improvements in or relating to tape dispensers
IPC: B65H35/00
Filed: 1959-12-29
Abstract: 900,806. Tape dispensers. BETTER PACKAGES Inc. Dec. 29, 1959 [March 25, 1959], No. 44120/59. Class 18.  In a tape dispenser driven by an electric motor, the act of depressing one of a row of push buttons causes a given length of tape to be dispensed, moistened and cut off. The tape is fed from a roll 22 along a table 26 where it is gripped between a roll 28, driven by a chain 50 and gears from the drive motor 54, and a pressure roll 30, passes through a cutter 32, 34 and over moistening brushes 36. A tank of water 42 has a heater 44 and is fed by a water bottle. A pressure plate 38 with an adjustable weight 40 presses the tape on to the brushes When a push button is depressed a solenoid 76 causes the cutters to open and the pressure wheel to move against the drive wheel 28 which is then driven by the motor to feed the tape. A trip magnet 122, Fig. 2, is also energized and operates a clutch 124 causing a sector 120 to rotate slowly by connecting the sector to a large gear 104 driven slowly by a pinion 106 on the shaft that carries the drive roll 28. The sector carries a resetting wheel 136 which engages a pin 114 extending inwardly from the push button that has been operated and resets the button and stops the motor. A spring 86, Fig. 3, causes the cutters to sever the tape. A spiral spring returns the sector 120 to its initial position where a clamping member 146 prevents the sector rebounding. The wheel 136 can be bolted to another position on the sector to alter the range of lengths that can be dispensed. A safety switch 162 at the end of the row of buttons trips the motor circuit if struck by the wheel 136 and a random button 172 causes tape to be fed so long as the button is depressed.

Title: Self-locking bevel differential gear for vehicles, more particularly for motor vehicles
IPC: F16H48/20
Filed: 1968-09-17
Abstract: 1,216,899. Differential gears. DAIMLERBENZ A.G. 17 Sept., 1968 [28 Sept., 1967], No. 44168/68. Heading F2D. A motor-vehicle limited-slip bevel-type'differential gear is locked by torque-responsive multi-disc clutch packs 22 biased into engagement by plate springs 27, whenever the output torque on one or other output shaft 25 vanishes, e.g. when one wheel loses traction. As shown, interleaved clutch discs drivingly connect the differential casing 10 to extended hubs of side wheels 15, 16 which are bolted at 17 to eliminate relative axial movement normally resulting from bevel gear thrust, and which are themselves connected through cam balls 30 mounted in continuous sinusoidal surfaces 28, 29 to flanged hubs 23, 24 splined to the output shafts 25, the plate springs 27 acting through the flanged hubs 23, 24 via thrust bearings 26. During normal drive, an axial thrust is generated at the cam balls 30 which acts through the flanged hubs 23, 24 to overcome the spring bias, releasing the clutches to permit unrestricted differential action. If either driven wheel loses traction, the driving torque and hence reaction thrust at the camming balls 30 is reduced, permitting the plate springs to re-engage the clutch packs to lock the differential gear. In Fig. 2 (not shown), the clutch engaging plate springs (33) are mounted between the back face of the flanged hubs 23 and a sleeve (34) supported on an axially adjustably screwed sleeve bearing (36, 37) whereby the tension of the plate springs (33) may be adjusted to compensate for service wear &c.

Filed: 1975-10-28
Abstract: 1532978 Pipe sealing apparatus G I BOUNDY 28 Oct 1975 [28 Oct 1974] 44220/75 Heading F2P A pipe sealing device comprises a support arm 2 and a sealing head 5 at one end of the support arm, the sealing head comprises a resilient sealing ring 8 between two plate members 6, 7. The sealing head is movable relative to the support arm from a first position in which the axis of the sealing ring 8 is aligned substantially parallel to the support arm 2 into a second position in which the axis of the sealing ring is substantially perpendicular to the support arm. Relative movement of members 6, 7 in the second position causes the sealing ring to expand or contract for peripheral sealing. Means to control the orientation of the sealing head and to cause the ring to expand and contract may be provided by a control lever 18 connected by a control arm 14 to a wedgeshaped plate 13. The latter co-operates with a slot 10 in central member 9 fixed to plate 6 and with a sleeve 12 fixed to plate 7 so that as it is pulled through the slot 10 it forces plate members 6 and 7 together. The device is placed down a riser 25 and the control arm 14 is then raised, this causes the sealing head to rotate until it reaches stop bracket 23. Further raising of the control arm pulls the wedge shape plate 13 thereby forcing members 6 and 7 together which in turn forces the resilient sealing ring radially outwardly into sealing engagement with the wall of the pipe 26. To maintain the sealing device in position a plate 22 engages in notches 21 on plate 20 secured to lever 18. In an alternative embodiment the control arm is raised by a screw thread arrangement (Figs. 4 and 5, not shown).
