Abstract: 818,316. Opening crimped filament tow. EASTMAN KODAK CO. June 25, 1957 [June 26, 1956], No. 20001/57. Addition to 769,936. Class 120(3) Crimped filament tow opening aparatus comprises a pair of driven rollers 2, 3, providing a bite for tow passed therebetween, a co-operating pair of retarding rollers 4, 5 which are braked or driven at a slower speed, the two pairs of rollers forming therebetween a tension zone through which the tow is continuously drawn and in which the tow is subjected to a tension which is sufficient substantially to straighten out the crimps, and a rockable device having a pair of spaced members 11, 12 positioned adjacent the tow in said zone and adapted to contact the tow and periodically to increase and decrease the tension in the tow while it is passing through said zone. In the arrangement shown the members 11 and 12 are in the form of striking bars carried on supporting arms 13, 14, 17 and 18 fixed to a sleeve 19 keyed to a shaft 15 which is rocked by cam mechanism driven by motor 20.

Abstract: 413,002. Accumulators. RULAG BATTERY CO., Ltd., 91, Farringdon Road, London.-(Rudolf, A. ; 12, Flemmingstrasse, Berlin.) Oct. 4, 1932, No. 20029/33. Divided on 407,723, under which a Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 6, 1932. [Class 53.] One or more of the conductors leading from the plates of a cell employing lead electrodes is covered with insulating material and is arranged to pass between adjacent plates to act as a spacing member or separator. Figs. 2 and 3 show a cell in plan and side views in which the plates 12, 13 are inverted, the lugs 14, 15 being connected to conductors 9, 8 which are provided with celluloid coverings 10 and which pass through the cell between the plates. The plate lugs pass through a false bottom 16 cemented to the walls of the cell near its lower end and the coverings 10 are cemented to the bottom 16 and cover 6. The cover 6 and bottom 7 are cemented in position to make the cell gas-tight. The plates of the cell may be constructed as described in Specification 407,723. The Specification as open to inspection under Sect. 91 states that the covered conductors need not be arranged as separators between the electrodes and that portions of the conductors may be formed as helices to increase the length and diminish creeping of the electrolyte between the conductors and their coverings. The conductors may be protected from the electrolyte by being embedded in the wall of the cell as shown in Fig. 4 (Cancelled). This may be done by passing the conductors through holes blown in the cell walls or by moulding the cell round the conductors. This subject-matter does not appear in the Specification as accepted.

Class 83 (iii). An automatic multiple spindle lathe comprises a spindle head, a fixed drive box spaced from the latter longitudinally, driving shafts in the drive box, shaft butts extending from the drive box, but not impeding the working space of the machine between the spindle head and drive box, the shaft butts being adapted to rotate synchronously with the shafts, cams carried by the said shaft butts, and additional tool slides on the spindle head adapted to be actuated by linkage operatively connecting them to cams carried by the shaft butts. In the application of the invention to a four-spindle work-turret automatic lathe, spindles in the head 11 carry the workpieces which are operated on by tools carried on a head 23 and cross slides 19, 20, 21. Operation of the tool slides is effected from drive mechanism in the gear box 12. A drive shaft 24 therein drives cam shafts 26, 26a, for the cross-slides and also cam shafts 50, 30a for the tools carried on the head 23. The latter cam shafts are extended at 31, 31a to project through the gearbox casing. These extensions may have cams 33, Fig. 3, secured thereto moving followers 35 which act through links 37 to move subsidiary slides such as 32 for turning, slotting, milling, or transverse drilling, in synchronism with the other tool movements.

Abstract: 1,143,121. Electrolytic capacitors. FUJITSU Ltd. 6 May, 1966 [7 May, 1965], No. 20296/66. Heading H1M. A wound solid electrolytic capacitor is manufactured by spacing an anode film bearing a dielectric oxide layer from a cathode film by means of a spacer made from a cellulose derivative having an ignition temperature below the temperature at which manganese nitrate decomposes to manganese dioxide, winding the electrodes and spacer, impregnating with manganese nitrate and heating to decompose the manganese nitrate to manganese dioxide and eliminate the spacer. Reanodizing is carried out after winding to repair faults arising therefrom. Impregnation and pyrolysis is repeated to increase the amount of manganese dioxide, and re-anodization also carried out after each pyrolysis. As shown, cathode foil 3 is separated from anode foil 1 bearing oxide coating 2 by a lacquer coating 4 of nitrocellulose, ethyl cellulose or methyl cellulose, the lacquer preferably incorporating fine manganese dioxide powder 5. Alternatively, a pre-formed film of the cellulose derivative may be used or the lacquer may be painted on a cathode previously coated with a layer of manganese dioxide by pyrolysis of manganese nitrate.

Title: Phototropic cells
IPC: G02B5/23
Filed: 1961-09-22
Abstract: A phototropic cell comprises spaced transparent plate-like members, a spacing member extending around the periphery of the plate-like members to define therewith a chamber and a phototropic film extending across the chamber and secured to the spacing member.  The rate of opaquing and recovery may be increased by incorporating in the cell a humectant film, e.g. of polyvinyl alcohol and glycerol, or by heating means.  In one modification electrically conductive coatings are incorporated and attached to a high frequency potential source suitably triggered, e.g. by means of a photo-electric cell. Ultra-violet and infra-red filters may be incorporated. Two phototropic films of different sensitivity may be incorporated, the more sensitive inner film being protected against burning out by the less sensitive outer film. Suitable phototropic materials are disclosed in Specifications 1,008,536 and 1,008,537, e.g. comprising solid solutions of polyvinyl alcohol, polyvinyl acetal, polyvinyl butyral, cellulose acetate or cellulose acetate hydrogen phthalate and a transition metal halide or an inorganic heteropolyacid. Films of these materials when oriented by stretching become strongly dichroic when opaqued, so that the efficiency of the cell may be increased by using two oriented films with the stretch axes perpendicular.

July 18, 1931, No. 20622. Convention date, Aug. 15, 1930. [Class 40 (iv).] In order to increase the response of a loud-speaker or transmitter at low frequencies, the front and back of the diaphragm are connected by an acoustic path, the mass and stiffness of which are so proportioned that the sound waves from the back of the diaphragm are brought into phase with and reinforce those from the front of the diaphragm-at low frequencies. In the moving-coil loud-speaker shown in Fig. 2, sound waves from the back of the diaphragm 7 pass through an opening 11 in the central polepiece into a chamber 5 lined with felt and communicating through a series' of tubes 4 with the other side of the diaphragm. The air in the chamber 5 and tubes 4 provide the stiffness and mass elements of the acoustic path. The sectional area of the tubes may equal the effective area of the diaphragm, and the mass of the air in the tubes may equal the effective mass of the diaphragm. In a modification, Fig. 6 (not shown), the chamber 5 is of cylindrical form and has a slightly curved base. In a further modification, Figs. 7 and 8 (not shown), the series of tubes 4 is replaced by an annular space defined by two cylindrical members. In the moving-coil transmitter shown in Fig. 9, the air-space 5 within the magnet 50 communicates by a tube 54 with the' outer side of the diaphragm 60 which is secured by a shallow tapered ring 55. The central polepiece 51 is curved. A ring 52 provides a small air chamber under the moving coil, this chamber being connected to the air-space 5 by a narrow passage 66.
