Title: Improvements in or relating to gear selecting arrangements
IPC: F16H3/36
Filed: 1957-01-24
Abstract: 819,151. Change-speed gearing. MAQUINAS AGRICOLAS ROMA S.A. Jan. 24, 1957 [Jan. 25, 1956], No. 2635/57. Class 80 (2). In a change-speed gear in which a first gear is arranged to selectively engage any one of a set of stepped gears by movements parallel and transverse to the common axis, the movements of the first gear are controlled by a single manually-operable means. A Norton-type change-speed gear in which a driving shaft 55 has an axially slidable gear 54 keyed thereto and carried in a supporting member 49 slidable on, and rotatable about the shaft 55. The  supporting member 49 also carries a second gear 52 permanently engaged with the gear 54 and selectively engageable with a series of stepped gears 53. The supporting member 49 is controlled by a hand lever 4 having angular movements 27, 28 transverse to the shaft 55 and also parallel to the shaft 55 about the axis of a control shaft 1. Initial movement of the lever 4 in direction 27 moves a cam 29 in a direction 30 along the control shaft 1 through movement of a fork 21 connected to the lever 4. Movement of the cam 29 causes a follower 44 to ride up a truncated conical face 46<SP>1</SP> and rotate a locking control lever 37 to contact the free end of an engaging member 64 and withdraw a catch means 60 from a locking recess 61 against the action of a spring 80, to unlock the supporting member 49. Further movement of the cam 29 in direction 30 allows the cam end face 46 to contact an abutment 45 on a lever 40, pivoted at 41, to cause the end 47 of the lever to contact the underside of the supporting member 49 and rotate that member about the shaft 55, against a spring 68, to unmesh the gears 52, 53. Angular movement of the lever 4 about the axis of the control shaft 1 swings a first control member 35, rigid with the shaft 1, and having portions 50, 51 located on either side of the supporting member 49, to move the member 49 axially along the shaft 55 for gear selection. The levers 37 and 40 are pivoted at 38 and 41 respectively on the member 35 and move with it. Movement of the lever 4 in direction 28 first allows engagement of the gear 52 with the selected gear 53 and then releases the catch means 60 to lock the supporting member in position. A chart, co-operating with pointers on the control member 5, is fixed to the casing 10 to indicate the ratio obtained.

Patent GB-973358-A (GB)
Title: Artificial filaments and spinnerets for their production
IPC: D01D5/253
Filed: 1961-01-25
Abstract: A spinneret for making hollow artificial filaments suitable for cigarette filters by dry spinning, has one or more orifices the cross-section of which normal to the axis of extrusion is in the shape of a crescent defined by arcs of circles of the same radius, one arc passing through the centre of curvature of the other arc. The spinneret may have orifices both of the crescent shape and of one or more other shapes.  The orifices may be arranged in one or more concentric circles in the spinneret face and the orifices of crescent shape may alternate with differently shaped orifices. When the spinneret is used for dry spinning, hollow filaments having the cross-sectional shape of a prolate split-ring with the split in one of the long sides of the ring and thus possessing a high surface to weight ratio may be produced.  They do not pack tightly even when mixed with filaments of other cross-sections, so that a bundle of filaments containing a substantial proportion of or consisting wholly of filaments of the above cross-section exhibit a high porosity and are therefore suitable for use in the manufacture of cigarette filters.  In an example, 90 bundles each containing 180 filaments produced by dry spinning an acetone solution of a secondary cellulose acetate (through a spinneret having 180 crescent-shaped orifices according to the invention) are joined together into one large bundle and passed through a stuffing box crimper to impart to the bundle an average of about 8 crimps per inch.  The crimped tow is opened in a conventional manner, sprayed with 6% of its weight of glycerine triacetate as a plasticizer and formed into a cigarette filter rod which is dried at room temperature for 2 hours to cause adhesion of the filaments to one another at points of contact.

Title: Machine for manufacturing sanitary napkins or the like
IPC: A61F13/15
Filed: 1962-01-29
Abstract: 964,541. Catamenial appliances. SCOTT PAPER CO. Jan. 29, 1962 [Feb. 2, 1961], No. 3228/62. Heading A5R. A machine for making sanitary napkins comprises a conveyer 33 for wrapper web material 32, means 31 for depositing pads 30 on the web, a series of web folding plates 41, 42, 43 and a series of rollers 44, 55 for ensleeving the web about the pads and positioning marginal strip portions of the web into upstanding abutting relationship and means for sealing the abutting strip portions together. Sanitary pads 30 are deposited at intervals by a conveyer 31 on gauze wrapper material 32 incorporating thermoplastic adhesive bonding material and moved continuously by a conveyer 33. Fixed converging horizontal wings 35 disposed above the wrapper conveyer define guides for the marginal portions of the gauze and with a tongue 37 define a throat through which the pads are guided as they pass below the wings. The marginal portions of the gauze pass over plates 41, 42, 43 which are fixed to the inner edges of the wings in oppositely arranged pairs of increasing inclination. The marginal gauze portions are flattened against each plate by resiliently mounted power-driven rollers 44 which also are slightly inclined in the direction of travel of the gauze to tighten the wrapper about the pads 30. The sides of the wrapper material are finally disposed in upstanding abutting relationship by passage between rollers 55 mounted on the plate, a vertical separator 56 being disposed between the wrapper sides. Thermoplastic adhesive is applied between the abutting sides of the gauze from a heated container 58 by a nozzle 57, the sides of the wrapper being then pressed together by passage between shoes 80, 83 which may be rotatable. Excess marginal wrapper portions 87 are removed by a cutter 88 and the completed seam is then flattened against the pad by a finger 100. The continuous wrapper sleeve 98 so formed about the pads is then passed between upper and lower chain conveyers 106, 107 (Fig. 19), the links of which support sets 108, 109 of thick transverse bars between which wrapper links 103, 104 between pads are gripped and sets 112, 113 of thinner transverse bars which define pockets for receiving the ensleeved pads. Chain conveyers 114, 115 (Fig. 20) disposed at each side of the travelling pads carry opposite sets 116, 117 of horizontal fingers 122 which are so disposed that, as a wrapper link portion 103 between adjacent pads enters between the upper and lower conveyers 106, 107, they indent the sides of the wrapper link to form tucks. The wrapped pads then pass between rollers 136, 137 having pockets 142 for receiving the pads and heated shoes 143, 140 between which the wrapper links adjacent the ends of the pads are ironed and heat-sealed. The sleeve 98 is then cut between the pads. The pads may be tapered and the apparatus arranged so that only the wrapper portions adjacent the narrower ends are tucked, the pads being delivered to the wrapper material so that the narrow end of one pad faces the narrow end of an adjacent pad.
