Abstract: 997,024. Seaming non-metallic sheet material. RIEGEL PAPER CORPORATION. March 4, 1963, No. 8574/63. Heading B5K. [Also in Division B8] A wrapper as shown in Fig. 2 and as described in Specification 934,523, primarily intended for wrapping bacon, is sealed to form a flat package by folding front and rear walls 13, 11 into face-to-face relationship, applying successively heat and pressure adjacent heat-sealable edges 16, 17 while the wrapper is moved along a predetermined path, re-orientating the wrapper through substantially 90 degrees in its own plane, and successively applying heat and pressure adjacent heat-sealable edge 18 during continued movement of the wrapper. The machine shown in Fig. 16 comprises a shoot 241, a main conveyer 240, an infeed auxiliary conveyer comprising spaced belts 262, 263 and an out-feed auxiliary conveyer comprising belts 281, 282. A wrapper having its front wall 13 uppermost and folded on to rear wall 11 is fed fold 14 first into the shoot 241 and is held flat between conveyer 240 and the infeed auxiliary conveyer while edges 16, 17 pass through longitudinal slots in heaters 242, 243 and thereafter between pressure applying fluting rollers 245, 246. A camming surface 273 on a vertical flange 272 causes a 90 degrees rotation of the wrapper to bring edge 18 within a longitudinal slot in a heater 244 as the wrapper is continuously moved forwardly by conveyer 240 and the outfeed auxiliary conveyer. Pressure is applied to edge 18 by fluting rollers 258 and 259 (not shown). If the wrapper is provided with a flange 19, a folding mechanism 290 (Figs. 3-5, not shown) is positioned before heater 244 to fold the flange on to front wall 13. In a modification, two main conveyers with their associated auxiliary conveyers are placed at right angles to one another (Fig. 1, not shown). In this case edges 16 and 17 are sealed during movement of the wrapper on one main conveyer and the wrapper is drawn off at right angles to its first direction of movement by the second main conveyer to effect sealing along edge 18. The auxiliary conveyers in both embodiments are each rotatable as a unit about their driving shafts (shafts 261, 283, Fig. 16) to facilitate inspection and maintenance of the main conveyers. An indicia-providing or dating mechanism (Figs. 8-10 not shown), may be incorporated with the outfeed fluting rollers.

Heading B7C. A tyre easing is removed from a tyre-building drum, which has been collapsed, by a mechanism 3 which has arms 2 which are operated to engage the exterior of the tyre casing and lift it clear of the drum and to deform the casing to free it from the drum. As shown in Fig. 1, the mechanism may be mounted on a carriage 1 which is axially displaceable by means of a fluid-operated piston- and-cylinder arrangement, the piston-rod being provided with a rack 14 which interengages with a gear in a gear train 15 having another gear which interengages with a rack on the carriage. As shown in Fig. 2, the tyre removal mechanism comprises arms 2 carried by levers 7 which are interconnected by a shaft 6. The levers are provided with pins 9 guided in slot 8 in the carriage 1 and joined to one end of links 10 which have their other end connected to a piston-rod of a piston displaceable in a pneumatic cylinder 11. In use, the carriage I is moved axially such that arms 2 are located under the tyre easing to be removed. Air is supplied to cylinder 11 to operate the piston therein to lift links 10 in the direction of the arrow A, see Fig. 2. This causes the levers 7, and hence the arms 2, to be lifted and to be moved inwards with respect to the axis of the drum, thereby lifting the tyre casing off the drum and deforming it to free it completely from the drum. The carriage 1 may then be returned to its initial position by supplying air to an appropriate chamber in cylinder 13 and the tyre casing may be removed from the arms 2 and discharged on to a conveyer.

Title: Improvements in train control mechanism for use on railways and the like
IPC: B61L3/12
Filed: 1921-03-21
Abstract: 174,559. National Safety Appliance Co., (Assignees of Folker, H. S.). Jan. 22, 1921, [Convention date]. Fluid-pressure. - Apparatus, in which the brakes are applied when magnetic means carried on the vehicle are influenced by magnets placed on the track, is constructed for control of vacuum brake systems. Similar apparatus for use with pressure brake systems is described in Specification 170,814. The brake pipe is opened by a pneumatic stop valve, which is opened by atmospheric pressure when a vacuum pipe is opened by a duplex valve carried below the locomotive or tender and normally maintained closed by the action of permanent magnets, the effective field of which is weakened on passing over an active permanent magnet fixed on the track. Two valves controlled by permanent magnets, the poles of which are reversely situated, are used on the train in order that one of these valves may always be released by the weakening of the magnetic force on the armature independently of the polarity of the track magnet, or by the weakening of one of the control magnets in relation to the other. Each track magnet has associated with it an electromagnet, controlled automatically by track-circuits, which neutralize the track permanent magnet under line-clear conditions. The arrangement of control magnets, and their coacting pole-pieces and inductor plates is similar to that described in Specification 170,814, the passages controlled by the valve being modified for control of a vacuum system. Fig. 1 shows the control valve F and the stop valve D and the manually operated releasing valve 302. The control valves connected to the armature 45 of each duplex magnet M, M<1> are double-seated valves serving, when the armature is raised, to connect conduits 131, 132 in the valve cap 70 and shut off these conduits from atmospheric pressure in the housing 22. When the armature is released, the flange 54 closes conduit 132 and atmosphere is admitted to conduit 131 through a side port in the valve seating. A ball valve 150 closes the connection to the other valve and conduit 132, which is connected by pipe 128 through a restricted passage 128<1> and the releasing valve 302 to the vacuum chamber. Air is thus admitted to the pipe 130 and the chamber C of the stop valve D. This valve includes a diaphragm 209 attached to the valve 203 which seats on. the flanged seating to' close chamber A from chamber B which is open by ports e to atmosphere. Air in the chamber C raises the valve and admits air from chamber B to the brake pipe T. To reset the duplex-valve, the releasing-valve 302 is turned to shut the pipe 118 and to connect the conduit 132 to atmosphere. The control valve being then subjected to equal pressure above and below, the magnet is able to lift it, and when the valve 302 is replaced the chamber C is exhausted and the valve 203 closes the train-pipe.
