Title: Improvements in or relating to the manufacture of cigarettes
IPC: A24C5/52
Filed: 1933-07-14
Abstract: 424,492. Cigarette-making machines. WIX, A., 338, Goswell Road, London, and MAY, R. F., 9, Manor Road, Potters Bar, Middlesex. July 14, 1933, No. 20021. [Class 130] Lengths of tobacco which are cut from a continuous rod are moved out of alignment therewith and associated with filter tips, the associated tobacco and filter tips being moved axially into engagement with means for applying a continuous paper strip to produce a continuous cigarette rod. In the construction shown in Figs. 4 and 5, a length of tobacco issuing from a collector tube 2 is severed by a cutter 3 and received in a bore 4<a> in an intermittently rotatable drum 4. Filter tips are fed by a plunger 19<a> into bores 7<a> in an intermittently rotatable disc 7, which is driven from the drum through pins 7c co-operating with slots 4<c>. When the bores 4<a>, 7<a> are in alignment, a plunger 5 pushes the filter tip into the bore 4<a>, and a picker 8 enters a slot in the plunger and passes through aligned slots 4b, 7b, in the drum and the disc to engage behind the tips and to eject the tobacco and the tip into the guide tube 9 of a rod-forming apparatus, which operates at a faster speed than the mechanism supplying the continuous rod of tobacco. To ensure that the bores 4<a>, 7<a> are accurately aligned, a pin 15 engages the lower pair of aligned bores before the plunger 5 enters the upper pair. The picker mechanism consists of two longitudinally reciprocating members 10 mounted on vertical slides 10<a> carrying the pickers 8 and having pins 10<b> engaging cam tracks 11<a> in a member 11 between plates 12, a spring-pressed pivoted member 10<c> ensuring the engagement of the pin with the upper part of the cam track on the return stroke. The pickers are bent outwardly at their upper parts to enable the lower part of one to pass freely over the lower part of the other on the return stroke. In modified constructions, (1) a double length of continuous tobacco rod is severed and a double-length filter tip is inserted from the disc, and the picker members 8 are mounted on the links of an endless chain ; and (2) the disc is dispensed with and the tips are inserted at the opposite end of the drum, either at a position in alignment with the tube 2 or at a previous stage, and the combined tip and tobacco portion is ejected either in the reverse direction to the travel of the tobacco rod by the picker mechanism described or in the same direction by utilizing picker devices having circular portions which abut against the tobacco charge.

Abstract: 1344277 Dispensing measured quantities of liquids ZYMA SA 19 April 1971 [21 Jan 1970] 20088/71 Heading B8N A liquid, e.g. soap, dose dispensing valve attachable to a container having a flexible wall and a rigid neck 1 comprises a substantially cylindrical body 2 open at one end and closed at the other end by a wall 3 provided in use with an outlet 4, a partition 9 provided with apertures 12, a valve disc 16, and a disc 17 of a diameter such that an annular gap E exists between the edge of the disc 17 and the internal wall of the body. The valve disc is integral with a rod 15 which extends through, and which carries a stop 15<SP>1</SP>, for the disc 17. The stop 15<SP>1</SP> may be adjustable on the rod. Springs 19, 20 urge the discs to their illustrated positions. The spring 20 may be dispensed with. For operation, closure member 5 is torn off and the container is inverted (as shown). Liquid passes through the annular gap E and fills the space between the disc 17 and the partition 9. Applying pressure to the container wall causes the disc 17 to move downwardly and simultaneously the valve disc 16 is moved away from annular rib 14 to allow the liquid to flow to the outlet. When the disc 17 contacts flange 9<SP>1</SP> of the partition dispensing stops. Upon release of the container wall the discs 16, 17 will return to their illustrated positions, the return of the disc 16 being assisted by or wholly effected by (if spring 20 is dispensed with) the reduced pressure created in the space between the disc 17 and the partition 9. In the alternative embodiment of Fig. 4, the partition 26 has, extending from its periphery, a skirt 26<SP>1</SP> which terminates in a seat 35 for the disc 32. When the disc 32 is in its inoperative position the space 33 is not in communication with the liquid in the container.

Title: Improvements in or relating to governor and transmitting mechanism therefor
IPC: B66D5/26
Filed: 1933-07-18
Abstract: 419,969. Speed governors. SMITH, D. M., 37, Church Street, Stretford, Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. July 18, 1933, No. 20290. [Class 57.] An inertia governor is employed to control the movement of a body or system capable of movement in both directions and is associated with a mechanism which discriminates between acceleration and deceleration so that the inertia governor is rendered inoperative during one of these changes when that particular change occurs in either direction of movement. Fig. 1 shows an inertia governor 34 as described in Specification 393,598 employed in a winding &c. gear as described in Specification 392,252, [Group XXXIV]. The brakes 2 of the gear are actuated by a weight 9 and a piston 12 subjected to pressure controlled by a valve 15 and a valve sleeve 35. The valve 15 is moved by a lever 86 or by the action of fluid pressure on the piston 16. The sleeve 35 is connected by linkage to the brake operating links to provide a follow-up movement. The inertia governor 34 is connected to a control valve 47 co-operating with a sleeve 71 which derives a follow-up movement from the brake operating linkage and also from a depth indicator. The discriminator 92 comprises a flywheel 97 driven by gearing 94 and resiliently mounted upon the shaft 93 by springs 100, 100<1>. A sleeve 111 secured to the flywheel is provided with ports 110. A member 101 is mounted upon a splined portion of the shaft so that it may move circumferentially a certain fixed amount and ports 112 are provided in an extension. A ring 102 is provided with pins 106 engaging the member 101 and also springs 103 so that it is pressed into engagement with the stationary ring 104. It is arranged that the ports 110 assume a central position but that the ports 112 assume one of two extreme positions according as to which direction the shaft 93 is rotated and due to the effect of the braking disc 102 and the play in the splines, so that the ports will align only upon one of the following, acceleration or deceleration, taking place in either direction of rotation. Mounted in a casing 105 is a valve 96 subjected on its face 123 to a fluid pressure and its larger face 121 is subjected to the same fluid pressure after passing through a restricted bore. The space 122 is connected through the bore 113 in the shaft 93 to an annular space leading to the ports 112. When the ports 110,112 do not align, the valve 96 will be retained in its lefthand position wherein the pipe 95 will be connected to exhaust and the connection between the inertia governor 34 and the piston 16 will be broken. However when the ports 110, 112 align, the space 122 is connected to atmosphere and the valve 96 moves to the right-hand position and the pipe 28 from the control valve 47 is connected to the pipe 95. Specification 298,691, [Class 57], also is referred to.

Abstract: 399,949. Copy - holders. RUF-BUCHHALTUNG AKT.- GES. and KÍLLIKER, E.. 19. L÷wenstrasse, Zurich, Switzerland. July 19, 1932, No. 20444. [Class 100 (iii).] In a clamping-device for holding bookkeeping sheets on a base during duplicate writing, which includes a clamping-bar 6, Fig. 1, for the account sheets 7 and an intermittently moving line indicator 9 arranged on the bar 6, the line indicator is loosely coupled by means of a spring-pressed pawl 10 with an actuating rack or rod 12 slidably arranged in the bar 6 so that only a forward movement of the line indicator is possible. The bottom or journal sheet A and the carbon &c. sheet rest against stops 36 on the base 1 and are retained on the latter by springs 37 fixed to a bar 2 hinged at one end 3 and retained at the other end by a spring-pressed pin 4. The bar 2 is provided with lugs a in which the bar 6 is rotatably mounted on a rod 5, the bar 6 being pressed by a torsion spring 20 to clamp the upper or account sheet 7. The bar 6 is marked with divisions corresponding to the divisions on the sheets and is slotted longitudinally at 8 for the reception of the line indicator 9. As shown in Fig. 3, which is a view from želow the bar 6, the indicator 9 is provided with a spring 33 which resists the movement of the latter, and the pawl 10 is engaged by a spring 11 to keep it in contact with the rack 12. The rack 12 is movable longitudinally, by means of a double armed lever 13 in bearings 35 on the bar 6, against the action of a spring 32. The lever 13 is mounted on a pin 34 on a handle 17 on the bar 6 and is slotted at 14 for the reception of a pin 15 on an angled lever 16. The lever 16 is pivoted on the handle 17 and its free end is bent at 21, Fig. 2, to engage an inclined slot 18 in a lever 19 secured to the bar 2. Downward movement of the handle 17 lifts the bar 6 and depresses the lever 16 which, by reason of its engagement with the inclined slot 18, is oscillated about its pivot ; this movement is communicated to the pivoted lever 13 which moves the rack 12 to forward the line indicator a distance of one division. On release of the handle 17 it moves back under the action of the spring 20 to its original position and the lever 16 is again moved to release the rack 12 so that it can move back to its initial position. The pressure of the spring 33 retains the indicator 9 in its new position during the backward movement of the rack 12. The indicator 9 may be moved independently of the rack by means of a handle 22 which on rotation brings the pawl 10 out of engagement with the rack. In a modification the actuating lever of the rack bar is engaged by a pin on an arm which is secured to a spindle on the operating handle. In this case, the indicator is moved by the rotation of the spindle, no movement of the clamping-bar being necessary. In a further modification the rack is provided with a simple projecting handle which is moved along the clamping-bar to forward the indicator.
