Patent GB-1468694-A (GB)
Title: Melt processing of fluorinated polymers
IPC: C08J5/22
Filed: 1974-07-29
Abstract: 1468694 Treating fluorinated polymers E I DU PONT DE NEMOURS & CO 29 July 1974 [1 Aug 1973] 33426/74 Heading C3P Fluorinated polymers having pendant side chains terminating in sulphonic acid, sulphonic acid salt or sulphonamido salt groups are treated to render them melt-processable by contact with a tertiary amine, a quaternary ammonium base or a salt of such an amine or base, with the proviso that free tertiary amine is not used when the terminal groups are alkali metal sulphonate. The process is especially useful for repair of ion exchange membranes used in electrolytic cells, which after said treatment may be repaired by melt-processing, e.g. by bonding a new portion of film to the damaged one. After repair, the treated film may be restored to its original chemical form, e.g. by ion exchange, though this is not essential. The process may also be used in recovery of waste or scrap material. In Examples, films formed from a copolymer of tetrafluoroethylene with perfluoro(3,5-dioxa-4- methyl-7-octene sulphonyl fluoride) are first treated with KOH solution to convert -SO 2 F groups to -SO 3 K groups, are then treated with various quaternary ammonium compounds, and finally two separate portions of the film are heat sealed one on top of the other.

Title: Improvements in and relating to wrapping machines
IPC: B65B11/14
Filed: 1930-11-07
Abstract: 362,617. Wrapping-machines. FORGROVE MACHINERY CO., Ltd. and GROVER, F., Oakhurst Avenue, Dewsbury Road, Leeds. Nov. 7, 1930, No. 33516. [Class 94 (i).] The machine wraps cylindrical objects, or cylindrical, elliptical or octagonal assemblies of coins or other objects, in cellulose sheet material or like transparent wrappers. The articles E are placed in pockets B on chains A and are carried, by intermittent movements, to position I to lie coaxially with formers F<1>, Fig. 3, one at each end of the article. A wrapper J is fed to the position shown in Fig. 1, and is then gripped against the former at each end of the article by a spring gripper H, which is moved by the operation of a rod I<1>. The formers are moved slightly apart to draw the leading edge of the wrapper taut and are then rotated to enclose the article as shown in Fig. 7. The grippers are released and the formers are withdrawn axially, provision being made for the ingress of air to the spaces vacated. By making the surface F<3>, against which the grippers press the wrapper, less protuberant than the general cylindrical surface of the former, accommodation is made for the slight movement of the grippers in the releasing movement. Lateral displacement during withdrawal is prevented by thin blades G<1>, Fig. 5, of segmented shape and adapted to impinge slightly against the outer edges of the object without interfering with the wrapper formation. The outwardly extending edges of the wrapper may be twisted or folded by known devices N.

As shown, the camera lens B is carried in a mount B<1> screw-threaded to the camera wall for focusing purposes. The rear edge B<2> of the mount B forms a cam acting on a roller C<1> carried by a lever C pivoted at C<2>, and carrying a second roller C<3> engaging with an arm D carried by a Dove's prism D pivoted at D2. The prism D inverts in a vertical plane the image entering through the window A<2>, and constitutes both the movable reflecting element of the telemeter and also the incidence pupil of the view-finder. The inclined semitransparent mirror E transmits the rays received through the prism D and reflects the rays received through the window A', a pentaprism F being provided behind the window A<1> to invert the image and reflect the rays down to the mirror E. The telescopic view-finder comprises an objective G, an eye-piece G<1> and a diaphragm G<2>. A second Dove's prism H inverts the image laterally.

In generating plant for a multi-engined aircraft wherein each engine drives, through a constant-speed device such as described in Specifications 604,285, 676,093, [both in Group XXVI], and 735,194, an alternator intended to work in parallel with those of the other engines, each alternator includes a polyphase rotor winding (which may also be used as the D.C. excitation winding) connected to a polyphase resistor which permit an unexcited incoming machine to be connected to the common bus. bars by closure of a main stator circuit switch. An auxiliary switch controlled by the main switch then allows an exciter machine to build up (by shorting out resistance in its field circuit) and supply D.C. to the incoming machine to effect synchronization. A second auxiliary switch operates automatically a predetermined time interval after operation of the first auxiliary switch and shorts out the polyphase rotor resistor.

Title: Improvements in and relating to the surface treatment of metal articles
IPC: C25D11/24
Filed: 1935-12-06
Abstract: The absorption of dyestuffs into anodic oxide films on aluminium or aluminium alloys is controlled by treating the oxide film with a weak aqueous solution of sodium or potassium mono-or di-hydrogen phosphate either prior to or simultaneously with the treatment with the dyestuff, the phosphate treatment being carried out at a temperature of between about 80 and 100 DEG  C.  The process is applicable only for those dyestuffs, e.g. Alizarine Red S or Anthracene Blue G.S.R., which can produce substantially permanent colours on aluminium oxide films without the use of a mordant.  The Provisional Specification is not limited to the treatment of anodically produced oxide films and refers also to controlling the absorption of oils, fats, and waxes.

In a variable resistor or inductor which comprises a helical winding 34, Fig. 1, on a former 18 the adjustable contact member 54 is of gear-wheel form and rotatably mounted on a carriage 44 so that the contact member engages the winding in the manner of a worm gear arrangement. The former 18 may be continuously rotated by the motor 30 via the gear train 28, 26, in which case the contact member 54 rotates and ensures good contact and even wear. In addition, the carriage 44 may be moved along shaft 14 to vary the position of contact, the contact member rotating as the carriage moves. It is stated that this form of contact member is of advantage where the member is lifted out of contact with the winding since it cannot, as opposed to a normal grooved pulley member, be replaced in the wrong position, e.g. between turns.
