Abstract: 1,110,914. Cigarette filter tips. CIGARETTE COMPONENTS Ltd. 10 April, 1967 [8 March, 1966], No. 10172/66. Heading A2C. In a method of assembling a wrapped filter tip in end-to-end relationship with a tobacco rod, or one or more wrapped filter elements in end-to-end relationship with another or other filter elements to form a multiple filter tip, to prevent the formation of air passages between the primary and secondary wrappers of the filter tip when the tip is either under or over size, the members to be assembled are brought into contact and alignment with one another, a paper or like wrapper is folded progressively about the assembly and the primary wrapper of the filter tip or of the said one or more filter elements is slit longitudinally. A succession of enwrapped plug elements 11 is fed to, and brought into endwise abutment by, a helically ridged drum 14, which delivers the elements 11 on to a continuous paper strip supported by a moving garniture tape 18. An endless belt 20, travelling at the same speed as the tape 18, in conjunction with a pressure foot 25, holds the elements 11 in place on the paper 17 while this paper is partially wrapped around them. The primary wrapper is then slit by a knife 26 rotating at the same circumferential speed at the linear speed of the advancing elements 11 when the paper 17 has taken the form shown in Fig. 8. Subsequent closure and sealing of the wrapper paper 17 is effected in known manner. In the manufacture of filter cigarettes, a circular knife is mounted to slit the wrapper of the filters to be attached to cigarettes at the point at which they pass axially from the feed hopper to the point at which they are attached to the tobacco rods.

Patent GB-400174-A (GB)
Title: Improvements in clutch
IPC: F16D43/14
Filed: 1932-04-13
Abstract: 400,174. Free-wheel clutches; variable-speed gearing. KELLER, R. E., 670, East Woodbridge Street, Detroit, Michigan, U.S.A. April 13, 1932, No. 10619. Convention date, April 13, 1931. [Class 80 (ii).] In centrifugal clutches for use in variablespeed gearing, a gripping-device slides centrifugally in an inclined plane on the driven member against the action of means tending to retract it from engagement. The clutch is described as applied to coupling the aligned driving and driven shafts 2, 11, Fig. 6, of a gear-box comprising a low-speed train 36-39 and a reversing-train 36, 37, 40, 41, 42 brought into action by a dog-clutch member 43 slidable on the layshaft 35, the wheels 39, 42 having freewheel clutches 44, 45. Thedrivenmember 7 of the centrifugal clutch, provided with lugs 14, 33, 34, Fig. 3, is retained against the face 5 of a driving- drum 1 by a lug 15 on a sleeve 9 and is slotted at 19, 18 to allow slight radial freedom on the driven shaft 11 and a pin 16 respectively. Equispaced clutch rollers 30, 31, 28 coact with inclined pockets 32, 29 respectively in the lugs 33, 34 and in a block 23, which is movable centrifugally in oblique guides 25 in the lug 14 against a light spring 26. The guides 25 allow sufficient play for the serrated inner face of the block 23 to ride over serrations 22 on the inclined face of the lug 14, inward motion of the block being limited by a second lug 13 on the sleeve 9. When the driven shaft 11 attains a predetermined speed through the gear train 36-39, the block 23 moves outwards and to the left to bring the roller 28 against the flange 4 of the driving-drum 1, all three rollers being then carried to the extreme shallow ends of their pockets, so causing the serrations on the parts 14, 23 partially to re-engage. Since the members 7, 23 do not then rigidly react on each other, no drive ensues until, by intentional retardation of the driving-member, the member 7, by virtue of the freewheel clutch 44, overruns and causes the rollers to pass to the deeper ends of their pockets and so allow further movement of the block 23 to bring the roller 28 into a shallow groove 6 in the drum flange 4. When, in this position, the shaft 2 is again speeded up, the rollers move towards the shallow ends of their pockets, but before they can complete the movement, the serrations fully engage and the rollers jam in the pockets to cause drive. After engagement, the clutch allows overrunning by normal action of the rollers, but, due to the groove 6, can only be completely disengaged by a second retardation of the driving-member to unlock the block 23 when the speed of the driven shaft is low enough for the spring 26 to overcome centrifugal force.

Aeroplanes; helicopters; propelling; steering and balancing.-A machine capable of horizontal and vertical flight has means for controlling the lateral and longitudinal equilibrium located in the airstream from the lifting screw or screws. a single control element being provided to move said means independently of one another to cause them to be acted upon more or less by the said airstream. A machine is shown having two lifting screws 15 on concentric shafts driven in opposite directions through bevel gear and a clutch from an engine 12 which also drives a forward propeller 11 through a clutch or reversible gear. Biplane supporting surfaces 2 have each an aileron 6 extending the full length of the wing, and tail planes 5, 10 with elevator 8 and rudder 9 are provided for use during forward flight. Two planes' 26, pivoted at 86 are adapted to be moved in and out of the fuselage so as to project more or less into the airstream from the lifting screws to control longitudinal balance during upward flight. The planes 26 and elevator 8 are connected by cords 80, Fig. 4, to a lever 79 on a transverse shaft 78 on which the lower part 60 of a transversely hinged lever 27 is secured so that fore and aft movements of the lever control the elevator and planes 26. The ailerons 6 are connected by cords 63, 64 to the lower end of a rod 61 capable of sliding in the lever 27, the ailerons hanging vertically when the rod is in its lower position and becoming horizontal when it is raised to its upper position. The rod 61 has a handle 62 and is locked in its upper and lower positions by a spring catch'. A balance wire 67 connects the lower sides of the ailerons and becomes taut when the latter are raised. The rod 61 is kept in its lower position during vertical flight and lateral movements of the lever 27 raise one or other of the pairs of ailerons on opposite sides of the machine more or less into the airstream independently of the other pair. During horizontal flight the rod 61 is raised and lateral movements of the lever 27 then move the ailerons on opposite directions from their horizontal position.

Title: Improvements relating to extrusion dies for plasticised matter
IPC: B29C48/09
Filed: 1956-04-09
Abstract: 798,527. Dies for extruding tyre tread bands &c. PIRELLI SOC. PER AZIONI. April. 9, 1956 [April 9, 1955], No. 10765/56. Class 87(2). An extrusion die is so designed that the resistance to flow of plastic material as it is forced through the die, by the surfaces of the orifice of the die, varies from point to point across the orifice with the height dimension of the orifice in the sense that the greater the height dimension from side to side of the orifice the greater the resistance to flow and vice-versa. In a die for extruding a tyre tread band, Figs. 5 and 6, L3, Fig. 6, represents the length dimension of the orifice at the portion 4, which has a height dimension h3. The two side portion 5 of the orifice decrease in height and length dimension in the direction away from the central portion, the minimum length dimension L6 being the minimum thickness of material capable of withstanding the extrusion pressure. The design of orifice is governed by the empirical formula where L<SP>1</SP> and L<SP>2</SP> are the greater and less length dimensions at two transversely spaced points, h<SP>1</SP> and h<SP>2</SP> are the corresponding height dimensions and n is a constant appropriate to the material being extruded. A deflector 6, opposite the central portion of the die and directed upstream, ensures continuous flow of the whole of the plastic material to the orifice. Fig.4 shows a die which tapers at 2 on one side of the orifice according to the above relationship; also means for varying the length dimension of the orifice in the form of a recess 3 on the downstream side. In a modification, a projection on the downstream side of the orifice may combine with a recess to provide in conjunction with the surfaces of the orifice proper, the required variation in length dimension, the passage of the material through those parts of the orifice of reduced height dimension being braked by the recess and the projection as it flows unhindered from the orifice. Specification 661,556 is referred to.
