Title: Modulating drive mechanisms
IPC: B41F13/00
Filed: 1973-01-12
Abstract: 1420471 Packaging apparatus BAKER PERKINS HOLDINGS Ltd 10 Jan 1974 [12 Jan 1973] 1690/73 Heading B8C [Also in Divisions F2 and B5] Cyclic variation of the rate of rotation of an output shaft 26 is derived from a constant speed input shaft 25 via two crank-link mechanisms 28, 30, 31 and 29, 32, 33 connected between each end of an intermediate shaft 27 and the input and output shafts 25, 26, respectively. The intermediate shaft 27 is movable by a pivoted bar 34 from a position coaxial with the input and output shafts 25, 26, in which the constant speed, i.e. uniform angular velocity of input shaft 25, will give an identical uniform angular velocity to output shaft 26, to selectively adjustable positions (Figs. 2A and 2B) laterally offset from but parallel with the coaxial (as shown) input and output shafts 25, 26 to provide the desired cyclic variation in the rotation of the output shaft 26 whilst maintaining one output revolution at shaft 26 for each revolution of the input shaft 25. The output shaft 26 may be connected to a printing die (24) or the sealing and cutting dies (19) or the web feeding rollers (21) when used on a moving web (16) of packaging material which is drawn around articles in a continuous tube form (17) in packaging machinery (Fig. 1, not shown) wherein different printing and packaging of different size articles requiring varying time periods for each machine cycle time are readily achieved. Various alternative cyclic variable crank-link mechanisms are illustrated in Figs. 8 to 12 (not shown). In the arrangement of Figs. 8 and 9, the input and output shafts (25, 26) are parallel to each other and connected via similar crank-link arrangements (31, 30 and 33, 32) to a pair of meshed gears (28A, 29A) arranged on a centrally pivotable bar (34) whereby cyclic variation is achieved as the bar (34) carrying the gearwheels (28A, 29A) is adjustably rocked about its central pivot (35). In the arrangement of Figs. 10 to 12, the input and output shafts (25, 26) are coaxially arranged in nested form, the intermediate shaft (27) being rotatably mounted in the bar (34) adjustably pivoted at (35) by a screw-threaded shaft (46), a disc (50) replacing the cranks (28 and 29).

Title: Improvements relating to the manufacture of pneumatic tyres or cases
IPC: B29D30/36
Filed: 1923-01-22
Abstract: 214,704. Walton, P. S. Jan. 22, 1923. Centrifugal machines; moulding wheel tyres.- Relates to the manufacture of pneumatic tyres, cases or carcasses and consists in subjecting the cavity of the tyre to centrifugal face derived by rotating a mass of liquid or a mass of comminuted mobile substance, e.g. metallic pellets. Fig. 1 shows one form of apparatus comprising discs 8, 9 mounted upon a hollow rotary shaft 1 and supporting peripherally an expansible or flexible member 13. The disc 8 is axially movable. The carcass 18 is secured over the member 13 by mould sections 14, 15 and bead rings 19 after which the shaft 1 is rotated and liquid is admitted to the shaft through a pipe 17 and passes through openings 16 into the space between the discs; or comminuted substance is fed in through holes 20 fitted with removable plugs. The centrifugal force causes distension of the member 13 and the drawing together of the discs 8, 9 and closure of the mould sections. Fig. 2 shows a modification in which, after expansion of the tyre by the mobile substance, the pressure is retained and the tyre transferred to a separate vulcanizing- mould. A turntable 27 supports a sectional mould 25, 26 within which the tyre is held by a clip ring 30 and bead rings 28, 29. A pipe 33 supplies comminuted substance to shoots 34 leading to the mould through pairs of conduits 32, 31 disconnectably coupled at 40 and furnished with non-return valves 35, 36. The introduction of the substance may be assisted by compressed air. The conduit 31 is fitted with a cap 41 to relieve the pressure.

[Class 51 (ii)] In an electrically-heated tunnel furnace for firing. porcelain or like ware re-' quiring a reducing atmosphere at a certain stage in the heating operation, the reducing gas, consisting mainly of carbon monoxide, is produced from solid and liquid fuels supplied to and partially burnt in stationary chambers located outside the furnace tunnel but in direct communication therewith. In the construction shown, a series of gas-producing chambers d is disposed in the side wall of the furnace, fuel, e.g. wood in small pieces, being fed thereto through ducts c by conveyers b arranged at the lower end of gas-tight hoppers a. The gas generated enters the tunnel through nozzles f in which are fitted the sensitive elements c of a carbon monoxide measuring device, the latter controlling the operation of the conveyers b and thus effecting automatic regulation of the carbon monoxide supply. When metal heating elements i are employed, the nozzles f terminate, as shown, flush with the inner face of the chamotte masonry h, but in the case of ceramic elements, they preferably project into the interior of the tunnel.

Abstract: 553,813. Winding electrical coils; severing webs of paper &c. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 18, 1942, No. 2138. Convention date, Feb. 18, 1941. [Class 120 (ii)] [Also in Group VIII] An electrical coil comprising a number of conductor layers with layers of insulation of gradually varying thickness between them is wound on a rotatable support carrying a former, the insulating material being cut longitudinally from a roll supported in the apparatus and the cutting means being moved transversely of the web as a portion thereof is wrapped on the former. As shown in Fig. 5 the insulating material e.g. paper is in the form of a roll 59 carried on a spindle 61 and the wire 57 is wound on a former 10 on a spindle 52 driven from a reversible motor 54: the paper of the roll 59 is cut spirally as it is drawn therefrom by a cutter 65, Fig. 6, carrying a wedge-shaped shoe 66 and pivotably mounted on a bolt 67 biased by a spring 69 and carried in a bracket 68 slidably mounted on a screw 70 arranged parallel to the winding spindle 52 and driven therefrom through gearing and a clutch 76; the bracket 68 carries a follower 71 normally forced into engagement with the threads of the screw 70 by a spring 72 and by selecting the gears between the spindle 52 and screw 70 the angle at which the web 62 is cut is determined. After a layer of wire has been wound on the former 10 the end of the web from the roll 59 is secured thereto, a number of full width layers of paper are wound on the wire layer, the follower 71 is engaged with the screw 70 at the right-hand end thereof, the wedge 61 is inserted between the web and the roll and the clutch 76 is engaged; when the cutter has slit the web a short distance the tapered end 63<SP>1</SP> is secured to the roll by an adhesive pitch 78 and the diagonally-cut portion 62 of the web is wound upon the wire layer and after the second layer of wire has been wound, the end 63<SP>1</SP> of the portion 63 of the web is secured to this layer and wound thereon- During the winding of the insulation layers the wire is wound on one of the drums 55, 56 at the ends of the winding spindle so that the wire at the end of each layer need not be severed. In a modification the web is severed by an electrical cutter carried by a support mounted on the screw which is driven by sprocket gearing from the winding spindle, the whole of the diagonally-cut web being wound on the wire layer and after the tapered end of the one part is secured to the coil, the other part of the web is rewound back on to the roll for use after the second layer of wire has been wound.

Title: Improvements relating to inhaling devices
Inventor: SCHACHNER HERBERT
IPC: A24F42/60
Filed: 1963-01-17
Abstract: An inhaling device comprises a nicotine-containing substance and means for heating this substance to a temperature at which nicotine vapour is given off.  The device is preferably shaped to simulate a cigarette but, when heating is obtained by combustion of a suitable substance, smoke and other combustion products are not inhaled.  In one form of the device a narrow bore tube 4, Fig. p  1 (not shown), of aluminium, containing nicotine extract or nicotine-enriched tobacco, is surrounded by combustible material 5, which may be tobacco, sawdust &c. treated with potassium chlorate or other substance to ensure continuous smouldering. When the tube 3 is thus heated, nicotine vapour is given off, condenses into aerosol form in a cooling chamber 2 and is inhaled by the user through a filter mouthpiece 6.  Several other arrangements are also described and it is also proposed to obtain heating by using finely divided metal which oxidizes on contact with the air.  Flavouring substances or other additives may be incorporated in the inhalant material.
