Abstract: 903,481. Actuation of switches. LOEWY ENGINEERING CO. Ltd. June 18, 1960, No. 21491/60. Class 38 (5). [Also in Group XXX] As a circular object 11 is driven along tracks 12 by a driven endless chain 13, it engages a feeler 16 and displaces it, together with a rack 22, to the right along guides 18 against the action of a counterweight 21, so that an arm 23a, pivoted to an arm 23b of a switch 25, ratchets over the teeth of the rack. When the feeler 16 starts to return from its position of maximum displacement, the rack pivots the arms 23a, 23b in a counterclockwise direction to actuate the switch 25 to cut out the conveyer drive motor 14. In a modification, the switch 25 actuates a timing device which cuts out the drive motor after a predetermined time delay, and in a further modification, Fig. 3 (not shown), the rack 22 is replaced by a ratchet-wheel and the counterweight 21 is replaced by a fluid pressure piston and cylinder or a torque motor.
Patent GB-215511-A (GB)
Abstract: 215,511. Kinnard, E. H., and Universal Postal Frankers, Ltd. March 21, 1923. Postmarking and stamp-cancelling machines; tripping-arrangements. - Relates to a machine for automatically cancelling and stamping letters or the like to a prepaid amount determined by the setting of a meter by the postal authorities and of the type in which the stamp drum is normally held inoperative by a trip gear, the invention consisting in the provision of a series of interchangeable dies which can be mounted in position to actuate one and the same meter to an extent proportionate to the value of the stamp printed. The trip gear employed is shown in Fig. 4 in the printing position, a pivoted finger 3 having by the entry of the letter being first pushed aside to rock the arm 4 and withdraw a roller 12 from engagement with a roller 22. This withdrawal allows of the printing drum, which is frictionally clutched to a constantly driven spindle 19, being driven until the roller 14 assumes the position shown with the rollers 12, 22 again in contact, the edge of the letter preventing the finger 3 from rising under the action of a spring 15 until the whole of the letter has passed, thereby preventing more than one operation of the printing drum irrespective of the length of the letter. The interchangeable stamp drum 30 is provided with gear teeth 34, the-number of which is proportional to the value of the stamp printed, and these teeth engage a pinion 37 transmitting motion to a meter 35. The roller 14 of the trip gear is carried in a bracket 22 on a sleeve 21 mounted concentrically with the spindle 19 and capable of being driven by the spindle through friction clutch elements, the pressure being adjustable by a nut 29, cross bar 26, and dogs 25. The printing drum 30 is secured to the sleeve 21 and rotates in a casing which is suitably cut away at the printing point. A detachable frame 16 forming the upper bearing of the spindle 19 is clamped in position by a wing nut 18 and carries the trip mechanism. When the drum and its casing are removed from the machine the printing-dies are in a position in which they are marked by the casing. This position may be maintained by a spring operated locking plunger freed by the entry of the drum into the machine. The meter is removed with its base plate 36, and all the gears, frame 16, trip mechanism and the printing mechanism, so that the portion of the base plate 36 surrounding the sleeve 21 may be lifted; thereby printing in the absence of the meter is prevented. If desired an auxiliary counting-device may be employed to totalize as the meter 35 gradually returns to zero.

Filed: 1923-08-27
Abstract: 205,059. Chenu, A. J. J. Oct. 3, 1922,. [Convention date]. Hydrogen.-The lifting gas of an airship is purified by passing it through a closed circuit containing a purifier which comprises an apparatus for liquefying any air contained in the lifting-gas. The purifying apparatus may be carried on a motor truck. The impurities may be replaced by additional lifting gas which may consist of Dowson gas after the elimination of the carbonmonoxide. The lifting gas in the case of airships having multiple gas bags is circulated from one gas chamber to another, the gas in each chamber being taken from the bottom and replaced at the top. Oxygen and nitrogen are removed by liquefaction in the apparatus shown in the Figure. The gas to be purified is drawn through a conduit 4 and compressed by a multiple-stage pump b, c, d cooled by jackets and water jets. The compressed gas is passed through a water separator e and a drying chamber f containing soda or lime which absorbs water and carbonic acid. The gases then pass through tubes g, extending through chambers p, l and through tubes h to a chamber i, the tubes h and chamber i being surrounded by a chamber n supplied with liquid air from a generating apparatus s. The purified gas escapes through a tube j to the chamber l, where it helps to cool the tubes g, and issues through the conduit 5. Air evaporating from the liquid in the chamber n, which may be kept under a depression, is led through a pipe o to the chamber p to cool the upper parts of the tubes g, and is withdrawn through a pipe q from which it may be conveyed to the generator s to be recondensed. The air liquefied in the chamber i may be withdrawn through a valve t and mixed with that in the chamber n or run to waste. The Specification, as open to inspection under Sect. 91 (3) (a), comprises also the removal of oxygen and nitrogen by means of carbide of calcium at a red heat or by means of calcium, magnesium, &c. This subject-matter does not appear in the Specification as accepted.
