Filed: 1928-03-15
Abstract: 308,887. Jardine, Ltd., J., and Ball, H. J. March 15, 1928. Ink-ribbon mechanism.-In ink-ribbon mechanism of the kind described in Specifications 146,609 and 265,011 the pawl plates connected to the universal bar to effect the ribbon feed are combined with a bar carried on the fixed part of the frame so that it can be moved longitudinally for the purpose of cross-connecting and transmitting the rocking movement of one pawl plate to the other to effect the automatic reversal of the ink ribbon. The pawl plates B are provided on their underside with studs E which project through slots G in the bottoms of the fixed spool-casings H, and a pair of. links C are connected between the ends of the universal bar A and the studs E. A bar J disposed parallel to the universal bar, with its ends resting upon fixed frame-bars K, is arranged to have a longitudinal movement which is limited by studs L on the bars K engaging slots J<1> in its ends, the right-hand slot being curved to provide two positions of rest in either of which the bar is held by a spring M. Arms O extending forwardly from the bar J are formed with slots O<1> to receive pins P on the pawl plates B, whereby the oscillating pawldriving movement transmitted to the pawl plates by the universal bar produces no effect on the bar J. The spool ratchets each co-operate with a detent S pivoted at S<1> on the spool casing H, and with a driving-pawl T pivoted at T' to the pawl plate B, an extension T<2> on the pawl T being so arranged that when the detent S is moved out of engagement with the ratchet wheel the driving-pawl is also disengaged. When either spool is exhausted a rocking motion is imparted to the pawl plates as described in Specification 146,609, the right-hand spool being the unwinding spool in the example shown, whereupon the pawl plates B, through the link J, are both swung to the left and an abutment B<1> on the right-hand pawl plate is moved away from the detent S, allowing the driving pawl to become operative for re-winding the ribbon. The link J and the pawl plates are moved to the right again when the left-hand spool becomes empty. An adjustable connection D is provided between the links C and the universal bar A, and a pin-and-slot connection between the member D and the links C enables the universal bar to rise and fall during case-shift without corresponding movement if the links.

Title: Improved process and apparatus for distilling or cracking hydrocarbons and purifying the vapours
IPC: B01J8/02
Filed: 1926-03-24
Abstract: 249,871. Gray Processes Corporation, (Assignees of Gray, T. T.). March 24, 1925, [Convention date]. Mineral oils, purifying.- In purifying hydrocarbon vapours by passage through a heated catalyst such as fuller's earth, bone-black, bauxite, kieselguhr, infusorial or other adsorbent earths, as described in Specification 222,481, a solvent, which may be a condensate from the process, is passed through the catalyst simultaneously with the vapours to remove polymerized products. The catalyst is heated by passing the vapours round the vessel containing it, or by providing the vessel with a steam or a heat-insulating jacket. The catalyst is supported in an inner vessel 15 on a perforated floor formed of wire gauze 17 held between perforated and slotted plates 16, 18. Hot vapours from an oil still enter by an inlet 12, preferably tangentially, the annular space between the vessel 15 and the outer vessel 14 and pass downwards through the catalyst to an outlet 36. A solvent liquid is distributed over the catalyst from a perforated pipe 25. The liquid collecting in the base of the vessel 14 may be passed into the still through a pipe 24 or through a trap 39. The catalyst may be discharged through a gate valve 31. If the vapour is passed directly into the catalyst, sufficient condensate to serve as solvent for the polymerized products is formed therein. The vapour supply pipe may be fitted with a valve to maintain the still under pressure, and to allow expansion of the vapours into the catalyst to regulate the temperature. Steam at temperatures up to 400‹ F. may be admitted to the catalyst chamber. A cooling coil may be placed above the catalyst to condense part of the vapours to form a liquid which acts as a solvent. A liquid seal may be formed between the base of the catalyst chamber 15 and the outer chamber 14. The vapours may pass upwards through the catalyst, which may be contained in a chamber mounted directly on the oil still.

IPC: B65H1/18
Filed: 1952-03-31
Abstract: 719,954. Feeding sheets. BLOCK & ANDERSON, Ltd., and HALL TELEPHONE ACCESSORIES, Ltd. March 24, 1953 [March 31, 1952], No. 8159/52. Class 100 (1). Pile tables; ; sheet-separators.- In a sheet-separating apparatus the pile table for the sheets is pivotally mounted at or near the end remote from that from which the sheets are delivered, and is urged upwardly at the free end by spring means controlled by an escapement which is itself controlled by a detector engaging the .top sheet of the pile, whereby the top of the pile is kept at a desired level. As applied to a duplicating-machine, the pile table 5 is pivoted about a fixed axis 3, and is urged upwardly at the back or delivery end by a roller 15 carried on one end 14 of a bell-crank lever secured to a shaft 16, the other end 17 of the lever being attached to a tension spring 18. A pile of sheets is placed on the table 5 between adjustable side plates 6 and the table depressed against the action of the spring 18 to bring the top of the pile to the level of a plate 10 which is secured to the machine frame. The shaft 16 is coupled to a shaft 28 through a number of gear-wheels and a one-way clutch, so that as the table 5 is moved, an escapement wheel 29 on the shaft 28 is rotated: the clutch allows free depression of the table 5. The rotation of the wheel 29 is controlled by a rocker 30 to which is attached a pendulum arm 31 carrying a weight 32. When the pendulum 31, 32 is free to swing, its natural frequency determines the rate of movement of the escapement wheel 29. The upward movement of the table 5 is arrested, when the top of the sheet pile is at the correct level, by the free end of a lever 34 embracing a pin 33 secured to the rocker 30. The lever 34 is pivoted at 35 and attached to a link 36 which is guided for vertical movement by a detector responsive to the position of the top sheet of the pile. As shown, this detector comprises a friction or combing roller 11 which feeds the sheets from the pile, the roller being carried by an arm 12 pivoted at 13 and driven by known means. An arm 40 secured to the arm 12 is adapted to engage a pin 39 on the link 36 so that if the roller 11 drops below a certain level the link is lifted to release the rocker 30 and allow the spring 18 to raise the table 5. A latch 41 on the arm 40 can engage in a notch 43 in a plate 42 to enable the roller 11 to be retained in a raised position during loading of the table 5. The lower part 10<SP>1</SP> of the fixed plate 10 slopes away from the table 5 and acts to register the sheet pile by displacing it rearwardly as the table rises. An adjustable trip, to prevent upward movement of the table just before the pile of sheets is exhausted and to operate an electric trip in the drive of the machine if the machine is driven electrically, comprises an arm secured to the shaft 16 adapted to operate a link which stops the rotation of the roller 11 and the machine when the arm has been rotated through a predetermined arc by the shaft 16.
