Filed: 1945-07-05
Abstract: 597,057. Making medical &c. capsules. FISHER, E. G. July 5, 1945, No. 17226. [Class 87 (ii)] In a method of producing capsules in which two ribbons of plastic material, e.g., of gelatine are separately and intermittently fed through a filling location at which they are brought into face-toface contact, and whilst stationary, a filling substance is injected between them to distend each ribbon to a pocketlike formation, the ribbons being then sealed therearound, the ribbons are pressed on an anvil all round the periphery of the capsule simultaneously, and whilst the pressure is maintained, the capsule is severed by a cutter co-operating with the anvil. In Figs. 1A and 1B, ribbons 5, 6 suitably lubricated by liquid paraffin, are intermittently drawn over rollers 7-12 and the surfaces of block 1 by feed rollers 2, 3 having raised portions 4. Block 1 is heated by electrical elements disposed in bores 18, 19 as in Specification 597,445 and at its apex, there are provided horizontal guides, housing presser members 37, 41, Fig. 5, operated against the action of springs 45, 46 by cam 42 and lever 44, and cam 43 respectively. Wh@gh ribbons are gripped by members 37, 4 capsule content material is forced between through nozzle 20 by the action of pump the upper sides of the pressure members being bevelled to accommodate the tip of block 1. The pump piston is driven by cam 31, and this, and a rotary plug distributing valve 27 are synchronized with the movement of the feed rollers 2, 3, so that liquid is drawn into the pump from hopper 25 when the ribbons are moving. The pump piston may be held out of action, e.g., during starting operations, by catch 33. When the liquid has been injected between the ribbons, cutter member 50, operated by cam 51 and lever 53 severs the capsule from the ribbons, and it is then ejected through aperture 67 in member 41 into chute 68 by rod 57 actuated by cam 58 and lever 62. The ribbons thereupon pass through feed rollers 15, 16 to a cutter 17. Any number of nozzles may be formed in the lower edge of block 1, and a corresponding number of sets of presser &c. elements provided.

Abstract: 430,859. Universal joints. RZEPPA, A. H., 3879, Audobon Avenue, Detroit, Michigan, U.S.A. June 12, 1934, No. 17431. Convention date, June 12, 1933. [Class 80 (ii)] A universal joint of the kind comprising inner and outer spherical members with meridian ball race grooves engaged by balls retained by an intermediate spherical cage member, has positive means for compelling an angular movement of the cage member substantially one half of the relative movement of the other spherical members. A cage member E, Fig. 1, is arranged with working clearance between a spherical member A on a shaft B and a spherical member C splined to a shaft D, and has slots to receive balls I which work in grooves F, G formed in adjacent faces of the members A, C. A spherical segment J abutting against the cage member E has a flanged opening J<1> to receive a ball K<1> on a pin K having spherical ends M, L respectively engaging cylindrical bores in the shafts B, D. The bore in the shaft D has a cup-shaped bush N<1> engaging the end L, and a spring P<1> in the shaft B keeps the pin K pressed towards the cup N<1>. The pin ensures movement of the segment J and consequently of the cage member E to keep the plane of rotation of the balls I approximately bisecting the angle between the two shafts. Fig. 5 shows a modification wherein the ball cage E<1> is engaged by a surface T<1> on a member T having two spherical surfaces T<3>, T<2> normally centred on the axis of the shaft D<1> at points on opposite sides of and equidistant from the centre of the joint. These surfaces engage corresponding surfaces on two members R, S, the member R being secured to the outer spherical member A<1> secured to the shaft B and the member S being splined to the shaft D<1>. Projections T', Fig. 6, on the member T engage recesses S<2> in the member S to cause the member T to rotate therewith, one projection being formed opposite each ball race groove in the member A<1> and the surface T<1> being defined by the faces of these projections. The member T and consequently the cage E<3> is constrained to tilt through half the relative angular tilting of the shafts B<1>, D<1>. The parts R, S, T are pressed together by a spring U with an interposed oil retaining pad V. The Specification as open to inspection under Sect. 91 contains a reference to U.S.A.

[Also in Groups XII and XXIX] An automatic controller for controlling the cyclical operation of the valves of a gate lock discharge system in a dust recovery plant comprises a shaft 17 carrying cams 9a, 9b operating balanced change-over valves 10a, 10b respectively and a piston and cylinder mechanism 5 adapted to rotate the shaft step by step through pawl and ratchet mechanism 7, 8. The valves 10a, 10b control fluid pressure servo-mechanisms 123, 119, 120 which in turn operate the valves of the gate lock discharge system. The piston and cylinder mechanism 5 is controlled by a change-over valve 24 moved in opposite directions under the control of valves 23, 23a operated through levers 28, 29 respectively alternately engaged by fixed collars 56, 57 on a'shaft 114. A lever 6 on which the pawl 7 is pivoted carries a cross head 27 which engages the adjustable nuts 18. The gate system comprises an upper chamber 30 and a lower chamber 116, controlled by flap valves 34, 31, 32 such that the valves 34, 32 are closed before the valve 31 opens, and the valve 31 are closed before the valves 34, 32 are opened. An equalizer valve 122 is provided to ensure that the negative pressure is the same in the lower chamber 116 as in the upper chamber 30, the hopper 115, and the compartment 33 before the valve 31 is opened. The valve 122 is operated by the servo-mechanism 123 under the control of the cam 9a and is first moved upwards to vent the chamber 116. A tappet 121 then operates a valve 35 which causes a servo-mechanism 36 to close the valve 31. On further rotation of the shaft 17, the cam 9b causes the servo-mechanisms 119, 120, controlled in parallel by the valve 10b, to open the valves 34, 32 so that material in the hopper 115 falls into the chamber 30 and material in the chamber 116 is discharged. On still further rotation of the shaft 17, the valves 34, 32 are closed, the equalizer valve 122 is lowered and finally the valve 31 is re-opened. Specifications 777,924, 777,925, [both in Group XXIX], and 777,926 are referred to.
