Title: Mechanism for rigidifying a collapsible object
Inventor: WARSAGER RUBIN
IPC: B41F19/06
Filed: 1970-05-04
Abstract: 1301122 Labelling machines R WARSAGER 4 May 1970 [27 March 1970] 21447/70 Heading B8F [Also in Division B6] A mechanism for rigidifying a hollow object to be decorated by the application of decorative material from a transfer tape comprises a base for supporting the object, an air-receiving opening in the base arranged to be contiguous with an opening in the object when supported on the base, sealing means on the base to engage the object firmly, a timer having means thereon to set an interval of time, an air valve operatively connected to the timer and means on the timer to selectively actuate means on the air valve to open and close the air valve, air lines connected to the air valve and the bass whereby air can pass through the air lines to the base in response to opening and closing movement of the air valve. As shown in Figs. 1 and 2, platform 19 is constrained to move in a vertical direction only and is moved up and down by the action of air cylinder 17. Mounted on top of the platform is a block 23 cradling bottle 25 to be decorated. As shown in Fig. 3 the block 23 has a seal 49 pressed into a counter bore 50 at one end thereof. The inner diameter of the seal 49 is dimensioned to receive the neck of the bottle 25 firmly so as to prevent air from leaking out of the bottle 25. Air flows into the bottle through the passageway 48 and through the opening in the seal 49. Transfer tape carrying the decorative material is fed from reel 26 over guides 28, between the object 25 and a die 30 and then fed between a pair of pull rollers 29 having a surface which grip the tape. The rollers 29 are rotatably mounted and can be driven by a motor (not shown) or can be actuated by hand to advance the tape after the pressing operation. The die 30 is fixed to a carriage 31 freely slidable on guide rails 33 under the influence of air cylinder 34. When the platform 19 is raised, a finger 37 thereon trips switch 38 which completes an electrical circuit to a conventional timer 39 electrically connected to solenoid air valve 41. The air valve includes a coil 42 which when energized attracts armature 43. Fixed to one end of the armature 43 is a coil spring 44 which serves to return the armature to its rest position. When the armature coil 42 is energized, passageway 45 aligns with passageway 46 permitting air to flow through the air supply lines to passageway 48 and into the bottle. The timer 40 at the end of a pre-set time signals the solenoid 41 to release the air by actuating the armature 43. This signal occurs one-half a second before timer 40 signals the air supply to the cylinder 17 to lower the platform 19.

Title: Improvements relating to the recovery of sulphur dioxide from products obtained in the treatment of mineral oils and tars or their distillates
IPC: C01B17/58
Filed: 1930-07-16
Abstract: <PICT:0364103/III/1> Sulphur dioxide is recovered from the products resulting from the treatment of mineral oils, tars and the like with sulphuric acid by heating a mixture of these products with a heavy residual oil and passing the evolved sulphurous gases, which are given off in an irregular manner, to an equalizing device consisting of a storage vessel in which they are subjected to such a pressure and held in such quantity as to enable them to be drawn off regularly as required.  The sulphur dioxide is used in the manufacture of sulphuric acid.  The heavy residual oil which preferably has an asphaltic base acts as a fluxing medium which causes the material to remain fluid and prevents coking.  In order to keep the hydrogen sulphide content of the evolved gases as low as possible the temperature of the mixture should not exceed 180 DEG C.  A mixture of kerosene sludge and a crude Mexican oil of asphaltic base is fed into a pot 1 heated by a furnace flue 2 and provided with a stirrer 3. The reaction commences when a temperature of 115 DEG C. is reached, the temperature being subsequently maintained at 160 DEG  C. The evolved gases pass to the top of a lead-lined container 6 which intercepts any solid or liquid material which may pass over and then to a condenser 9 in which they are cooled.  Any water present is thus condensed and collects in a vessel 11 while the gases proceed through a pipe 12 to a scrubber 13 fed with sulphuric acid.  The dried gases pass to a compresser 15 which delivers the gases under pressure to a storage vessel 16 which should have considerable length.  Here the sulphur dioxide liquefies and any condensed hydrocarbons float as an upper layer on this liquified gas.  The liquid sulphur dioxide can be used directly for the manufacture of sulphuric acid.  Two storage vessels may be provided, the sulphur dioxide being continuously removed from the first to the second, which would also be maintained under pressure.  The scrubber 13 may be followed by another scrubber in which the gases are freed from hydrocarbons by such materials as silica gel or gas oil.  Specification 319,673, [Class 91, Oils &c.], is referred to.

Title: Aircraft instrument
IPC: B64D43/00
Filed: 1946-07-20
Abstract: 614,689. Aircraft indicating instruments. SQUARE D CO. July 20, 1946, No. 21740. Convention date, Aug. 4, 1945. [Class 4] An aircraft indicating instrument comprises a pointer and relatively movable dials graduated in terms of indicated airspeed and angle of attack to show values of these factors under all conditions of operation, the arrangement being such that the dials do not move relatively to each other under constant loading conditions regardless of changes in airspeed and angle of attack. Fig. 1 is a sectional elevation of the complete instrument and Fig. 2 a diagrammatic arrangement of the chief components. The pointer 32 is mounted on a shaft 31, and the angle of attack dial 61 on a sleeve 58 enclosing the shaft 31, while the airspeed dial 62 is fixed to the instrument casing. The top portion of the dial 61 is graduated in terms of percentage of load, and the scale also bears markings 86, 87 denoting the stalling angle, and the angle corresponding to maximum lift to drag ratio, respectively. A capsule 12 is connected at 14 to a pitot head and moves the pointer 32 in accordance with airspeed through a linkage 16, 17, shaft 18 and a toothed sector 24 engaging a pinion 33 on the shaft 31. The dial 61 is rotated in accordance with variation in angle of attack by a self-synchronous transmission system, the transmitter 74 of which is operated by a wind vane 75. The shaft 37 of the receiver 35 carries a lever 38 which engages a slotted lever 43 on a shaft 44 carrying a pinion 46 which meshes with a pinion 47 rigid with a rotary frame 48. A shaft 52 is mounted within this frame and carries two planetary pinions 53, 54, the former of which gears with an idler pinion 55 engaging a second toothed sector 23 on the shaft 18, the sector meshing with a pinion 57 integral with the sleeve 58 carrying the dial 61. In the event of change in angle of attack without variation of airspeed, the sector 23 and pinion 55 remain stationary, the movement of the frame 48 causing rotation of the planet pinions 53, 54, and consequent rotation of the pinion 57 and dial 61. If a change of loading occurs at constant angle of attack, the frame 48 remains fixed and the sectors 23, 24 rotate the dial 61 and pointer 32 through equal angles. At constant loading the consequent changes in airspeed and angle of attack result in movements of the sectors 23, 24 and the frame 48 such that the dial 61 remains stationary. To compensate for operation of the flaps 73, the latter are connected to the stator of the receiver 35 through cam mechanism 71, a flexible shaft 69, pinions 66, 65, a shaft 64 and gearing 63, 36.
