Abstract: 339,559. British Thomson-Houston Co., Ltd., (Assignees of Acheson, M. A.). Feb. 21, 1029, [Convention date]. Vacuum tubes.-Anodes forming part of the envelopes of transmitting valves, particularly generators of very high frequency oscillations, comprise spaced concen. tric cylinders 21, 24, Fig. 1, joined at their upper ends, the lower end of the cylinder 21 being closed to form a chamber for the electrodes which are supported from the other end of the envelope, and the lower end of the cylinder 24 being ring- sealed to the glass 1 to re-enter the envelope. The sealing-ring 23 may be integral with, and of larger diameter than, the cylinder 24 and in line with the envelope as shown or the ring may extend outwardly from the cylinder 24 and be sealed to a short re-entrant part of the glass 1. A partition 25 and chamber 29 may be provided for cooling the anode by circulating water, oil or air. The cylinder 24 may be longer or shorter than the cylinder 24. Within the cylinder 21 are successively a helical scrceen-grid 20 on a collar 7 with a side-lead 12, a helical control grid 19 on a collar 8 with a, side-lead 11, and a cathode comprising two V -shaped filaments 15 connected to flexible leads 17. A sufficient distance along the surface of the glass between the grid lead and the anode is thus obtained with short electrodes and electrode supports, and interelectrode capacity is thus reduced. The screen-grid 20 may be omitted. The Specification as open to inspection under Sect. 91 (3) (a) comprises also modifications in which the cylinder 24 is replaced by a glass tube 34, Fig. 3 (Cancelled), sealed to the top of the cylinder 21 by a ring 23 and in which the chamber 21. is shortened to form a hemisphere. This subject-matter does not appear in the Specification as accepted.

Abstract: 139,513. Kiefer, K. April 21, 1917, [Convention date]. Bottling.-In a machine for filling bottles &c. with viscous or like substances, the bottles &e. are fed by an endless system of carriers 57, Figs. 1 and 2, beneath the delivery spouts 15 of a distributing-head 10, which rotates beneath a stationary controlling-head 17 having a passage 18 to which the substance is supplied by a pipe 33 from a force pump 27. The head 10 is adjustable vertically on the shaft 6 by means of a hand-wheel 13, and the head 17 is held stationary by a radial spur 15 engaging an upright 26 secured to the table 2. The spiral-gear pump 27 is driven by sprocket gearing 47, 48, 49 from a shaft 46<1> driven from a vertical shaft 42 which carries a friction-disk 41 driven by a frictionwheel 40 on the driving-shaft 38. The wheel 40 is adjustable by means of a fork 51 operated by a hand-wheel 53 to regulate the speed of the pump, and the vertical shaft 6 is driven by worm gearing 35, 37 from the shaft 38. The detachable carriers 57 are carried by a chain 58 passing round sprocket-wheels 9, 59, and each carrier has downwardly-extending lugs 69, Fig. 5, between which the hook 71 of one link and the cross-bar 72 of the next link of the chain engage. Between the wheels 9, 59, the lower sides of the chain links slide along on the top of the bottom bar 61 of a trough 60. Ribs 74 on the outer part of each lug 69 bear against the inner side of the adjacent rail 62 of the trough 60, and ribs 75, 76 on the under side of each carrier bear on the top of the rails 62. A series of gauges 78 mounted on a disk 79 above the wheel 9 on the shaft 6 is provided to centre the containers. Each gauge comprises diverging arms 80 and a slotted shank 81 which is bolted to the disk 79. A flat opening 84 causes the containers 57 to move in between the arms 80. For use with bottles, a mouthcentring attachment consisting of a split hub with diverging lips is clamped to each spout 15. Fig. 8 shows a modification for filling containers to an uniform height.

Title: Improvements in locks
IPC: E05B63/20
Filed: 1934-02-23
Abstract: 428,489. Locks. GIBBONS, Ltd., J., and GIBBONS, F. J. J., Church Lane, Wolverhampton. Feb. 23, 1934, No. 5978. [Class 44] In a lock having a bolt withdrawable by a key, and a handle which is not connected to but can follow the movements of the bolt, means are provided which prevent movement of the handle when the bolt is in the fully protruded position. A bolt a is pressed upon by a spring b and lever b<1>, and is guided by a stud a<2> and slot a<1>. A key inserted at d engages a shoulder a<4> on the bolt after lifting tumblers e, f, which have slots e<1>, f<1> and gates e<2>, f<2>. A stump a<5> on the bolt is located in slots e<1>, f<1>, when the bolt is fully shot, and in the gates when the bolt is withdrawn. When the bolt is partly shot the stump is in the slot f<1> and gate e<2> the slot f<1> being considerably wider than the slot e<1>; this causing the tumbler f to drop before the tumbler e. An arm h<1>, of a follower h', h<2>, fixed to a spindle i, to which an external handle is attached, contacts with a shoulder g on the bolt. The arm h<2> touches a head k<1> of a rod k due to a spring l pressing between the head and a fixed surface k<2>. The tumbler e has an arm m with a block m<1> at its extremity which touches the inclined end of the rod k when the tumbler is dropped, i.e. when the bolt is fully shot. When the tumbler e is raised, the block m<1> is held clear of the end of rod k, thereby permitting movement of the latter, the handle and the follower h<1>, h<2>. A blade spring c, riveted at c<1>, carries a detent block c<2> which engages a lug a<3> on the bolt a when the latter is fully retracted. A button c<3>, on the spring c, projects from the lock casing and engages the door jamb when the door is closed to move the detent laterally out of engagement with the bolt. Fig. 5 shows a modified arrangement in which a bell-crank lever o<1>, o<2>, replaces the plunger rod mechanism. A tumbler n has a slotted arm n' which engages the lever o<1>, pivoted on a stud o. The handle spindle i and follow h<1>, h<2> are located below the bolt a. When the tumbler n is raised, the arm o<1> is also raised, thus allowing movement of the follower. A stop p is provided. A coiled spring i<1> maintains the follower in contact with the bolt. Specification 13209/11, [Class 44], is referred to.

Abstract: 588,904. Printing-surfaces; printing processes. AUTOGRAPHIC BUSINESS FORMS, Ltd. (Autographic Register Co.). March 10, 1945, No. 6018. [Class 100 (ii)] Hectograph master sheets, which may be either mirror script or unreversed (for transfer to a gelatine surface), are made by superposing a continuous strip of master-form material on a strip coated with hectograph ink, printing either on the outer side of the form material to produce a mirror-script copy on the back or on the non-coated side of the coated strip to produce a positive, and inserting a continuous, protective strip between the coated strip and the hectograph-printed surface of the master strip. A web 10 perforated along the middle line 12, or slightly off that line, and coated on one half 11 is folded along the line 12 with the coating inside the fold, and is printed in a press 15. A protective strip 16 from a supply roll 18 is interposed between the folds by means of a turning bar, after which further printing is effected at 21, .marginal feed-perforations are punched in the strips at 19, and the strips are perforated transversely at 29, cut transversely by a knife 26 and delivered into a box 28. The transverse cutting may be omitted and the strips delivered folded zig zag, in which case the protective sheet may be removed continuously during use, e.g., by means of a turning bar. Part of the printing- surface of the press 15 may be soft rubber types which print without transferring the hectograph coating. Where the line of perforations 12 is slightly off the middle line, the bottom sheet of the final assembly projects beyond the protective sheet the width of which is such that this sheet projects beyond the top sheet, whereby removal of the protective sheet is facilitated.
