Title: Improvement in electrical condensers
IPC: H01G13/02
Filed: 1927-01-18
Abstract: 273,239. Dubilier Condenser Co. (1925), Ltd., (Assignees of Nyman, A.). June 24, 1926, [Convention date]. Condensers are made by winding alternate sheets 2, 4 of rubberized cloth and foil, respectively, on a rod 5. The cloth is wound on reels 1 and may be muslin covered with rubber in uncured form so that the condenser when finished can be vulcanized. In the course of finishing, the condenser may be pressed into the form shown in Fig. 2, the foils being connected to terminals 7, 8, or, if desired, the winding may be effected so that the edges of the foils project as shown at 4 in Fig. 3. The cloth is wound on the rod 5 to a slight extent before winding the foils, and the rod 5 is removed when the winding is finished. The invention is applicable to other than wound condensers. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of any materials capable of being influenced by heat. This subject-matter does not appear in the Specification as accepted.

Title: Tracked vehicle systems
IPC: B61B13/08
Filed: 1972-01-13
Abstract: 1430761 Magnetically levitated transport systems G R POLGREEN 9 April 1973 [13 Jan 1972] 1604/72 Heading B7L In a magnetically levitated transport system comprising a track of magnetic material formed by steel rails 2, a vehicle has a magnetic suspension system including permanent magnets 6 which are attracted upwardly to the rails 2 so as to balance the weight of the vehicle. The ferrite brick-magnets 6 are provided with mild steel polepieces 8 which extend beyond the magnets to have coils 10 wound thereon. A magnetic circuit is formed between each magnet 6 and the track through the polepieces 8, and the flux in this circuit may be varied by the passage of current through the coils 10 without permanently reducing the strength of the magnet 6. As shown in Fig. 2, each rail 2 is L-shaped with a horizontal limb associated with a respective magnetic rail 4 on the vehicle for vehicle suspension, each rail 4 comprising a series of the magnets 6 equipped with the polepieces 8 and coils 10, and a vertical limb associated with a further rail 4 for lateral guidance of the vehicle. When no control current is flowing through the coils 10, the lifting force of the magnets 6 is such that the associated rails 4 are normally held in contact with the downwardlyfacing surface of each horizontal limb of the rails 2. Current is then passed in a direction to reduce the flux density sufficiently for the vehicle to be suspended without direct contact with the rails. In another form, as shown in Fig. 3, a central polepiece 32 is provided which can be moved vertically relative to outer polepieces 26 to thus vary the flux in the magnetic circuit, only the central polepiece 32 being provided with a control coil 34. When an increase in the weight of the vehicle occurs, a spring 41 is compressed and a linkage rotates a cam 48 beneath each central polepiece 32 to raise the piece 32 through its coil 34 and thus increase the lift exerted on the vehicle.

In an arc-welding machine for joining stationary pipes end-to-end, the welding rod is oscillated transversely of the joint, the direction of the transverse movement being adjustable. When welding pipes, whose axes are inclined to horizontal, the direction of transverse movement is maintained horizontal by manual adjustment as the welding rod moves round the joint of support 30, Figs. 1 and 2, consisting of semi-circular members 32 interconnected by struts 38, 64 is secured on a pipe 24 by chains 48 tensioned by toggle devices 50. The members 32 carry rollers which retain and guide a movable semicircular frame 66 to which are fixed chains 90 engaging with motor-driven pinions 96 mounted on opposite ends of the support 30. A plate 108, Fig. 5, pivotally mounted on the frame 66 is urged by a spring 164 towards the pipes and telescopically carries rods 120, 122 connected to a bracket 126, Fig. 3, journalling a roller 158 engaging the pipe 24. A manuallyoperated bell-crank 178 is operable to lift the roller 158 clear of the pipe 24. A platform 202 supported by the bracket 126 so as to be adjustable radially of the pipes 22, 24 by a hand wheel 188 carries bearings 212 in which is journalled a sleeve assembly 208, Fig. 8. The welding head 230 has arms 236 pivotable in the sleeve assembly 208 and is connected through links 342, 312 and 334 to an eccentric 322 driven by a motor 316. Amplitude and direction of the transverse movement of the welding head are varied by altering the pivot point of the link 312 by a hand wheel 292 and by rotating the sleeve assembly 208 by a hand wheel 274, respectively. A reel 346 and a feeding device 350 on the frame 66 supply an electrode to the welding head 230 which is provided with an expendable guide tube extension 260 connected by a coupling 262. Welding current is supplied to the welding head by a cable 250 and carbon dioxide is fed through a tube 354 to shield the welding zone. An enclosure 360 connected to the bracket 126 and provided with a removable transparent panel 358 and a shroud 366 of asbestos webbing surrounds the welding zone. The bracket 126 and so the welding head 230 is adjustable along the pipes by actuation of a motor 140 on the plate 108. The welding head 230 is moved at welding speed from the 12 to the 6 o'clock position on each side in turn and is returned at a faster speed. Two welding heads working in opposite directions may be used.

Title: Improvements in or relating to the manufacture of lactones
IPC: C07D315/00
Filed: 1960-01-20
Abstract: A lactone is prepared from a ketene and an aldehyde by a modification of the liquid phase process claimed in the parent Specification, wherein methanol is used as solvent for the anhydrous aluminium chloride catalyst in place of the aliphatic ester there specified. The catalyst solution is preferably prepared by adding the aluminium chloride to the methanol while preventing the temperature exceeding 25 DEG C. Desirably, the solution contains at least 15% by weight of the catalyst; other catalytic ingredients e.g., zinc chloride may be present.  In an example, propiolactone is prepared continuously by feeding an equi-molar mixture of ketene and formaldehyde into a mixture of propiolactone and a methanolic solution of A1 C13, containing a minor amount of Zn Cl2; a make-up supply of catalyst dissolved in methanol is provided and propiolactone product is continuously withdrawn.

The slide C has marks labelled with units of weight in various systems, while the slide D has marks appropriately disposed and labelled with units of volume in the same systems, both sets being marked in black, so that by setting the black scales C, D relative to one another according to the specific gravity of a liquid corresponding weights and volumes may be read off in any system by moving the slides together as set to appropriate positions relative to either of the fixed scales. Similar conversions between price per unit volume may be made by using the red A.P.I. gravity scales in conjunction with red labels of price on slides C and D. Scale plates U and V, logarithmically graduated, are provided for money conversions between dollars and sterling by setting according to the rate of exchange, and may be replaced by similar plates for other currencies. Conversion scales for conversions between different temperature scales may be provided.
