Abstract: 195,621. American Dan Bottle Seal Corporation, (Assignees of Clark, W. L., and Hawkins, W. J.). April 1, 1922, [Convention date]. Capsules and like closures; cap-stoppers, screw. -A closure for a bottle &c. provided with a protuberant bead 8, Fig. 4, and a groove below the bead comprises a malleable metal cap 5 having the lower edge of its flange 6 condensed and hardened within the groove by the application thereto of pressure applied to all parts of the flange edge at the same time by rigid cold-swagings means which confines and hardens the metal to form an anchoring band. The actual seal occurs mainly around the lower exterior surface of the bead 8, and its effectiveness is increased as the internal pressure acting on the imperforate top of the cap increases. The interior of the cap or the exterior of the bottle neck and bead may be coated with gasket-forming material 10 such as plastic gum, wax, balsam, or gelatine, the material preferably being insoluble and without odour or taste, and a cork or other insert mav be used. The cap may be formed of thin aluminium, and may be formed from a disc on the bottle mouth. or it may be preformed as a cap as shown in Fig. 1, tear-off tabs 4 being provided. The closure may be housed by a cap 20, Fig. 6, with a skirt 19 screwed on to threads 18 on the bottle neck. Reference has been directed by the Comptroller .to Specification 10337/03.

Abstract: 345,485. Winding, stranding, coiling or lapping machines. LARMUTH, J. H., Hill Crest, Upper Colwyn Bay, Carnarvonshire. March 15, 1930, No. 8359. [Class 120 (ii).] In a winding, stranding, coiling, lapping or like machine the bobbin spindle is locked in the bobbin cradle 1, 2, Figs. 1 and 2, by two slide members 5 which are moved simultaneously into the locking or unlocking position by a third member 10.

Title: Method for the preparation of iron electrodes
IPC: H01M4/30
Filed: 1975-02-28
Abstract: 1492621 Making iron electrodes WESTING- HOUSE ELECTRIC CORP 28 Feb 1975 [14 March 1974] 8417/75 Heading B3A [Also in Division H1] A method of making an iron electrode comprises mixing particulate iron with an organic mouldable resin, moulding the mixture into an electrode shape and heating the moulded shape to at least 950 C. in an inert atmosphere to carbonize the organic resin. The particulate iron comprises an iron powder, an iron oxide or an iron hydroxide and a preferred mixture is formed of Fe 3 O 4 , carbon black and a phenolic moulding powder in a weight ratio of 8 : 1 : 2. The carbon black provides a favourable porosity for the electrode and maintains the conductivity between the carbon matrix structure and iron oxide, which shrinks during the carbonizing step. The resins should be mouldable at a temperature not greatly in excess of 200 C., preferably 100 C. The strength of the electrode may be increased by utilizing carbon filaments or nickel fibres. Alternatively a metallic screen may be incorporated in the mixture prior to moulding.

Abstract: 526,450. Training aircraft pilots. SHEKLETON, A. March 16, 1939, No. 8438. [Class 4] Relates to devices for training aircraft pilots and of the kind in which horizontal movements of an aircraft in flight are represented by the movements of a " crab " which moves over a graph sheet and is operated by aircraft controls on a dummy fuselage.

Title: Improvements in or relating to sideband transmitters for communication systems
IPC: H03C1/60
Filed: 1953-03-27
Abstract: 725,354. Modulating systems; multiplex radio signalling. CROSBY, M. G. March 27, 1953 [March 27, 1952], No. 8466/53. Class 40 (5). A single-sideband transmitter comprises a carrier amplitude modulator supplied with a phase-modulated carrier, the modulating signals being derived by detecting the amplitude and phase modulation respectively in the output of a known single sideband modulator. In one embodiment the primary modulating signal and an auxiliary carrier from oscillator 3 are applied to a single-sideband modulator 1. The resultant carrier phase modulation is detected by circuit 13, fed with carrier from source 1 and with the single sideband output, after passing through limiter 11, and is used to phase modulate the main carrier generated in circuit 17. The phase-modulated output from the latter is passed through amplifier 19 to the amplitude modulator 9 feeding the aerial 21. The modulating signal for circuit 9 is derived by detecting the amplitude modulation, produced in modulator 1, in circuit 5, the output from which is amplified by the amplifier 7. The circuit 1 may comprise two carrier suppression modulators supplied with different modulating signals, the upper sideband of one and the lower sideband of the other being selected by filters, Fig. 2 (not shown), so that the energy radiated by aerial 21 carries one signal on one sideband and a different signal on the other. Some carrier is passed to the output of modulator 1. In order to synchronize the two modulating signals, applied respectively to the phase modulator 17 and amplitude modulator 9, a time delay equalizer 15 is included in the output circuit of the phase detector 13. In a modification, negative feed-back is provided by circuits which detect the phase and amplitude modulation components in the output of the final modulator 9 and subtract them respectively from the modulating signal inputs to circuits 17 and 9, Fig. 4 (not shown).

Laminates, having an embossed, compact layer up to 3 mm. thick of rubber, or rubber coated with a thin sheet of synthetic resin, and a foamed rubber or synthetic resin backing, are prepared by placing the precursor layers into an engraved preheated suction mould, applying a vacuum, and heating either the mould or the mould placed in a press in an autoclave in order to vulcanize or set the sponge and unite the layers. The mould is preheated to a temperature below the vulcanization temperature of the rubber and the setting temperature of the resin. Fig. 4 shows the laminate a, b in the mould which is held between press plates e and g, the latter carrying the lid of the mould h which presses the peripheral portion f of the laminate projecting from the chamber i. After vulcanizing the pressed and moulded laminate may be trimmed to obtain chamfered edges.

Abstract: 319,724. Union Special-Maschinenfabrik Ges. Sept. 27, 1928, [Convention date]. Addition to 305,530. Thread - cutters for severing the enchained stitches between stitched articles of the kind described in the parent Specification, are provided with means for laterally moving the movable cutting knife which also has a guide finger. The movable knife 6 is carried on the arm 8 of a lever 8, 11 pivoted at 9 on a bracket 10 carried by the presser bars 4, 4. The knife is normally held out of action by the spring 28. When the presser foot 3, 3 drops on to the work plate 1 owing to the absence of any work, the recess 21 in the arm 12 pivoted to the arm 11 at 13, descends to engage the toe 24 of the lever 17 carried by the arm 18 constantly oscillating in the pivot 20 owing to a connection 19 operated by some part of the machinery. This causes the lever 8, 11 to be rocked about its pivot 9 to impart cutting motion to the blade 6 until the presser foot is again lifted by the arrival of work thereunder. A blade-spring 29 with an inclined side engaging the set-screw 32, Fig. 3, is carried on the bolt 30 in the bracket 10. The blade 6 is thereby given a lateral movement away from the leger blade 5 on its upstroke and towards it on its downstroke. The lateral movement on the downstroke is arrested by the contact of the guide finger 7 with the leger blade 5.

A carton closure flap folding and sealing machine has rotary flap folding means to contact the underside of leading and trailing flaps of cartons being advanced through the machine, and to lift and infold the flaps under a stationary sweep. The invention is described as applied to the machine set out in Specification 966,547, the single rotary sweep being replaced by two rotary sweeps mounted on a vertical shaft 40. The leading flap sweep 43 has an arcuate triangular head 45, the tip 48 of which passes below the leading flap 18. As the sweep 43 rotates and the carton advances, the flap 18 rises up along the edge 46 and the stationary sweep 47 pushes the flap 18 down over the carton top. The trailing sweep 49 has an arm 54 and cam follower 56 at opposite ends, the sweep 49 being vertically pivotable about pin 53 by a fixed cam 58 against the bias of spring 60. As the sweep rotates, the cam causes it to rise abruptly whereupon the flap 19 is raised and then passes over the carton top so that the flap is pressed down for passage under the sweep 47. The cam 58 may be rotatably adjusted using screws 63 whilst a vertically adjustable rail 64 may be used to accommodate package variations.
