Title: Improvements in or relating to photographic film
IPC: G01J1/42
Filed: 1948-10-01
Abstract: 651,068. Photographic films. KODAK, Ltd. Oct. 1, 1948, No. 25689. Convention date, Oct. 2, 1947. [Classes 97 (i) and 98 (ii)] A photographic light-sensitive film has a transversely-extending latent image of a sensitometric strip in each of a selected number of areas which are intended to or serve to separate consecutive latent picture images. A film 10, Fig. 1, having a sensitometric strip image 14 in every space 14 which separates consecutive picture images 12, has the usual marginal perforations 11 and at one side of each image 14 a small perforation 15. The sensitometric strip images 14 may be formed on the film by contact-printing either before or after the usual exposure of the film. A contact printer for this purpose comprises a continuously rotating sprocket 32, Fig. 2, a slit 33 and a light source 34. Sprocket 32 has teeth 35 for engaging the perforations 11 of film 10 and a series of small teeth 36 for engagement with the perforations 15 in the film 10 and with similar perforations in a negative 37 bearing transverse images of a sensitometric strip. The picture images 12 may be formed by exposure of film 10 in a camera which includes a claw 24 carried by an arm 22 which reciprocates under the control of a cam 21 carried by a sprocket 19 and rotatable in an aperture in the arm 22. The sprocket 19 meshed with a sprocket 18, which also carries a cam 20. This cam engages a yoke 25 mounted on a reciprocable rod 26 having at one end thereof a pin 29 for engaging the film perforations 11 and a pin 30 for simultaneously engaging the perforations 15. Specification 346,189 is referred to.

Title: Process and apparatus for manufacturing hollow articles of a thermoplastic material
IPC: B29C48/09
Filed: 1958-08-11
Abstract: 845,059. Extrusion-centrifugal moulding machines. PATELLA, L. Aug. 11, 1958, No. 26692/58. Class 87(2). A process of moulding hollow articles of a thermoplastic material comprises extruding softened material 50 on to the inner surface of a cylindrical mould 32 so that the material lies in helical convolutions 51 whilst rotating the mould at a relatively low speed and heating it during the laying-down step to maintain the material in its softened condition, centrifuging the material in the mould at a high speed so that the convolutions 51 fuse together and then cooling the material to form a unitary body. Thermoplastic end pieces 33, 34 may be placed in the mould 32 so they fuse to the convolutions and the convolutions may be laid in more than one layer and of different materials. An axially movable tube 17 has a discharge orifice or orifices 20 through which plastic material is forced by a ram 23 into a mould 32 rotated on rollers 31. Two such tubes may discharge into the mould, one from either end. The tube 17 and ram 23 are mounted on a rotatable bracket 19 having an extrusion barrel 11 and distribution chamber 14. In operation the tube 17 is withdrawn until the orifice 20 is within the chamber 14 whereupon the pressure of the plastic material within the chamber 14 forces back the ram 23 and fills the tube 17, the volume contained by the tube 17 being adjustable by a ram stop 24. The tube 17 and ram 23 are then advanced in the mould 32 and differential withdrawal of the tube and ram extrudes the helical convolution 51. Rotation of the bracket 19 enables the tube 17 to discharge into a second mould whilst the material in the first mould is centrifuging.

Abstract: 443,693. Valve circuits ; holders. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Sept. 16, 1935, No. 25696. Convention date, Sept. 15, 1934. [Classes 39 (i) and 40 (v)] For generating ultra-high frequencies, two or more oscillator valves are connected symmetrically to a common resonator comprising two hollow hemispheres S1, S2, Fig. 1, mounted on the ends of an axial rod or tube A, A. The rod and the metal surface of the hemispheres constitute the inductance, and the space between the flanges F1, F2 the capacity of the resonator circuit, which is matched with the valve impedance. The oscillator-valves may be connected to the resonator as shown in Fig. 2, in which case the grids are energized in phase ; or they may be coupled non-uniformly when it is desired to produce harmonics for frequency-changing, the grids then being excited in phase-opposition. The valves may be mounted inside the hollow resonator. Or as shown in Fig. 3 they are only partly enclosed by it. The axial rod A then serves as one of the filament leads to the valves R1, R2, the other lead running inside it. The plate supply Ea is connected to the hemisphere S1, and the grid voltage Eg to the hemisphere S2, these two being insulated from each other at C1, C2.

Filed: 1924-10-28
Abstract: 231,422. Owens Bottle Co., (Assignees of Corner, A. N.). March 31, 1924, [Convention date]. Rotary conveyers.-In an apparatus for receiving bottles or other articles from a forming machine and conveying them to a lehr or to other apparatus, the articles are placed one by one in an upright position on a plate and are moved over it on to a travelling conveyer by means of a series of pockets. The bottles fall on to a shoot 11 and slide, neck foremost, until they strike a stop 13 whence they fall back in an upright position on to a plate 12. A bottle, as it falls on to the plate, is received in one of a number of pockets each comprising vertical side plates 16, 17 and a back plate 18. The plates 16 and 17 are attached to a disc 20 secured to a shaft 22 which is rotated step-by-step by the forming machine, and the plate 17 is attached to a lower disc 21. This disc is loose on the shaft but is adjustably connected to the upper disc, so that the two discs rotate together but may be adjusted angularly to one another in order to alter the width of the pockets. The plate 17 is resiliently attached to the disc 21 to enable it to yield if a bottle is caught by an obstruction. The rotation of the discs pushes each bottle over the plate 12 and deposits it on a conveyer 19 which carries it out of the pocket to the lehr.

Title: Improvements in or relating to welding machines
IPC: B23K5/22
Filed: 1931-09-16
Abstract: 371,744. Uniting by fusion. SVENSKA AKTIEBOLAGET GASACCUMULATOR, Liding÷, Stockholm. Sept. 16, 1931, No. 25948. Convention date, Oct. 2, 1930. [Class 83 (iv).] In a gas welding machine, the wire, bar or other additional material is rotated or oscillated about its longitudinal axis while being fed to the joint so that different surfaces of the material are presented in turn to the welding flame, the material being thus melted uniformly all round. The wire 2 may be fed to the flame 1 by discs 4 rotated by a flexible shaft 5 on the disc portion 6 of a holder 3 which is oscillated by a band 10 reciprocated by a pair of eccentrics &c. The lower portion of the holder is eccentrically mounted in the bearing 9a of a fixed arm 9 so that at the same time it is oscillated laterally of the joint. In another form, Figs. 4 and 5, the wire is rotated by discs 23 carried in adjustable spring-pressed bows 21 pivoted at 24 on a toothed wheel 12, which is rotated by a pinion 18 through a flexible shaft. The wheel 12 is rotatably mounted in a bearing 14 on a plate 13 secured to a frame 11, which is journalled at 43 in a fixed arm 44 and is oscillated across the joint by an eccentric &c. The axis 50 of the journal 43 is inclined so as to diminish the oscillations in the upper part of the wire. The wire is fed by one or more edges 29, Fig. 7, or discs placed obliquely so as to act as nuts and formed on or carried by cylindrical members 30 mounted in a non-rotatable member 31. The members 30 are pressed radially inwards by springs 32 and may be withdrawn by a hand-operated cam 42 to facilitate insertion of the wire. The member 31 is carried by a plate 38 attached to the frame 11 by screws 39 passing through large or oval holes so as to allow lateral movement thereof due to kinks or variations in thickness of the wire. The rate of feed may be varied by adjusting the inclination of the edges 29. For this purpose the ends of the members 30 are provided with arms 34 engaging grooves 34a in a disc 35, which may be rotated by a handwheel 36 through worm gear 37. In a third form, Fig. 10, the holder 3 may be rotated continuously by a band 10, and the feed effected by edges or discs as in the previous form, the member 31 being mounted on the frame 46 by a screw 39 and enlarged hole so as to allow lateral movement thereof. The Specification as open to inspection under Sect. 91 (3) (a) states that the invention may be applied to electric welding machines. This subject-matter does not appear in the Specification as accepted.

Filed: 1944-12-28
Abstract: 642,083. Cathode-ray tubes. COSSOR, Ltd., A. C., and WOODBRIDGE, L. A. Dec. 28, 1944, No. 25964. [Class 39 (i)] A cathode-ray tube has apertures in the anode or first anode and also preferably in the grid of the electron gun off-set to one side of the tube axis and magnetic field means for deflecting the beam to the desired path in order to prevent negative ions from reaching the fluorescent or other screen of the tube. In the construction shown the parallel rods 2 and spaced insulating discs 3 support the grid 5 with off-set aperture 12 in dished portion, the first anode 8 with off-set aperture 13, the cylindrical shield portion 9 and the anode diaphragm 10 with central aperture 14. A permanent or electromagnet is arranged to develop in the cylinder 6 a magnetic field for deflecting the electron beam into coincidence or parallelism with the axis 11-11 before it emerges from the aperture 14, the negative ions collecting on the inner wall 9 of the cylinder 6. The aperture 13 overlaps the aperture 12 in a direction parallel with the axis 11-11 and the cathode 4 and grid aperture 12 lie in or closely adjacent the plane of the supporting insulating disc 3 to avoid effects of tilting of the disc 3. Dimensions are given.

Title: Fibrous material
IPC: D04H13/00
Filed: 1975-09-10
Abstract: 1522952 Fibrillated film fabrics LAMBEG INDUSTRIAL RESEARCH ASSOCIATION 10 Sept 1975 [12 June 1974] 25980/74 Heading D1R [Also in Division B5] A fibrous material used in the production of fabrics and consisting of fibres having helical crimp or a precursor for such material, is produced from films of molecularly-orientable synthetic thermoplastic semi-crystalline organic polymer material, e.g. polypropylene, which after drawing to a high degree of uniaxial orientation have a tendency to fibrillate, by a process including melt-laminating two of the films, one being thicker than the other, and the thicker film only being characterized by surface modification or mechanical working or both. The surface modification comprises subjecting the film in an unoriented condition and molten deformable state to the action of a travelling surface having a homogeneous series of discrete depressions or protuberances numbering at least 10,000 per square inch to give rise to a corresponding series of discrete protuberances or depressions on the film and cooling the film to a non-molten state in which the protuberances or depressions are substantially retained. The mechanical working comprises mechanically working the film during transition from plasticized to unplasticized state to cause internal movements which break up spherulites forming part of the material structure, e.g. by passing the film after extrusion into a nip between a metal chill roll surface and a rubber roller or belt which may be provided with protuberances or depressions. The thinner film which may be produced in an air knife/chill roll casting unit, may be bonded to the thicker film at the nip and a coating of polyethylene powder carried by the rubber belt may also be applied to the thicker film at the nip, the polyethylene subsequently being used to bond together the resulting fibres. The laminated films may be stretched during passage through an oven and fibrillated on a pinned roller fibrillator. The helically crimped fibres may be spun into a bulked yarn or needle punched and/or solvent bonded using the vapour of an halogenated hydrocarbon to produce a non-woven fabric. A supported non-woven fabric may be produced by needle punching the fibrillated laminate whilst laid on a woven tape fabric.

[Also in Division B8] Draft force is applied to a rope 1 by pairs of grippers 19, 19<SP>1</SP> attached to links 11, 12 of an endless chain (see Division B8). The grippers 19, 19<SP>1</SP> are mounted on arms 15, 16 pivoted at 13, 14 to the links 11, 12 and are forced into contact with the rope 1 by the lever action of rollers 17, 18 engaging spring-loaded cam surface 20 and cam surface 20<SP>1</SP>, respectively, as the chair is driven by a ratchet mechanism operated by a reciprocatory hand lever 37 freely pivoted on a shaft 7. Pivoted on the lever 37 is an arcuate rocker member 42 having a pair of oppositely projecting pawls 38, 39 engaging gears 34, 35 respectively. The gear 34 is fast with the shaft 7 which carries a chain-driving sprocket 5. The gear 35 is rotatably mounted on a shaft 36. When the lever 37 moves clockwise (as seen in Fig. 4) gear 34 is driven clockwise by pawl 38, pawl 39 ratcheting over gear 35. When the lever 37 is moved anticlockwise gear 35 is driven anticlockwise by pawl 39 and drives gear 34 clockwise, pawl 38 ratcheting over the gear 34. When the lever 37 is stationary both pawls 38, 39 are engaged and the system is locked. The drive may be made unidirectional by disengaging either pawl 38 or 39 by levers 43, 44 respectively. If both pawls 38, 39 are disengaged the load (not shown) will drop and may be braked by an oil gear pump 45. A gear 47 meshes with a gear 46 keyed to a shaft 52 connected through a one-way drive (not shown) to a sprocket 6 over which the endless chain is entrained. Oil from a reservoir 51 passes through an adjustable flow restricting valve 49, the flow, and hence the braking action, being controlled by a knob 50. A filling plug device 53 includes a spring-loaded plunger to take up variations in the volume of oil due to temperature variations.
