Title: Sheet conveying device for rotary printing machines
IPC: B41F21/08
Filed: 1932-02-23
Abstract: 384,488. Rotary printing-machines. TURNBULL, D. H., 10, Reginald Terrace, Chapeltown Road, Leeds. Feb. 23, 1932, No. 5322. [Classes 100 (i) and 100 (ii).] In a rotary printing-machine the sheets are conveyed through the machine by grippers on a carrier which is guided by a closed cam path and which does not release the sheet until it is printed. The release may be delayed until delivery occurs, and the carrier passes in turn under the control of feed or delivery chains which are driven at a variable speed to receive or deliver the sheet, but are driven at the time of sheet transfer at the same speed as the chain which carries the sheet through the printing- couple or couples at a constant speed. In one form, Fig. VIII, three chains passing over pulleys a, b; b, c ; c, d are employed and the dark line indicates the path of the gripper carrier 21, Fig. II, which is formed with extensions fitted with runners 5 which move in a closed cam track 6 which constrains the carrier to move in the path indicated. The method of transferring the carrier from the first pair of chains 10 to the second pair of chains 9 is shown in Figs. I and II. Extensions 7 of the gripper carrier are engaged by curved links 8 of the chain 10, and as the chains 10 pass over pulleys 12 which are driven at a variable speed by elliptical gearing 14, 16, 17, 18, the extensions 7 are transferred to similar links 8 on the chains 9 which are keyed to a shaft 13 driven at a constant speed. From the chains 9 the carrier may be directed to a further pair of delivery chains driven at a variable speed, or the sheets may be released from the gripper carrier and pass to a separate delivery chain.

Patent GB-578016-A (GB)
Title: Improvements relating to fibres, films and the like
IPC: D01F9/04
Filed: 1943-03-05
Abstract: Filaments, fabrics, films, or the like made from solutions of alginic acid or alginates, are impregnated with an aqueous solution of a protein and the treated articles are then subjected to the action of an insolubilising agent for the protein.  The protein may be added to an aqueous coagulating bath into which a solution of an alginate is extruded to form the filaments, films, or other articles.  The treatment improves the strength, particularly the wet strength of the fibres, films and other articles, and imparts resistance to swelling by water.  The protein may be glue, gelatine, casein or albumen.  The insolubilising or hardening agent may be formaldehyde, a chromium-containing salt, or a natural or synthetic tanning agent. In an example, fibres composed of calcium alginate are steeped in a 1 per cent solution of gelatine and then removed and dried. They are then immersed for 1 minute in a hardening liquid comprising water, formaldehyde, ethyl alcohol, acetic acid and chrome alum.  The fibres are allowed to dry in the air.  In another example, fibres of aluminium alginate, prepared by treating calcium alginate fibres with a solution of aluminium sulphate, are hardened in a similar manner.

Filed: 1938-02-21
Abstract: 510,468. Boots and shoes. SCHOLL MFG. CO., Inc. Feb. 21, 1938, No. 5435. Convention date, March 4, 1937. [Classes 17 (i) and 17 (ii)] A cavity 21, Fig. 6, of a shape in keeping with the fleshy parts of the foot surrounding the os calcis is made in the inside sole part before or after its incorporation in a shoe, at a position which is to be located under the os calcis, by grinding away material of the insole. Other cavities 23, 24 may also be ground out from the inside sole part under the first and fifth metatarsal heads. These cavities serve to increase the bearing area over which the weight of the body is distributed. Where a foot-arch support is worn inside the shoo, the heel part of the insole may be ground out to a depth equal to the thickness of the part of the support under the heel. A burr or tool 9, Fig. 4, comprising a base 10 of comparatively soft metal in which is set a plurality of knives 11, of hardened steel preferably extending radially of the base with bevelled inner ends, may be employed to form the cavities. It may be mounted in a stand and driven by an electric motor when used on insoles, or, as shown for use in forming the cavities in finished footwear, the tool may be mounted on a flexible shaft passing through an angularly bent handle 15 at the forward end of a flexible casing 14. Specification 4658/07, [Class 17], is referred to.

Abstract: 1377426 Television MESSERSCHMITTBOLKOW-BLOHM GmbH 7 Feb 1972 [10 Feb 1971] 5591/72 Heading H4F In the photography of a subject from an attitude stabilized satellite or missile an image of a subject is formed by a lens 6, a plurality of linear image regions lying end-to-end are derived from the image,.and each image region is directed on to the photosensitive screen of a different electron beam scanning tube, 101, 102. As shown, image regions corresponding to areas 41, 42 are reflected by separate reflecting strips 71, 72 formed on prisms 121, 122. For colour photography lenses 91, 92 are each replaced by an assembly of two lenses with a dispersion wedge between them so as to produce on the vidicon screens an image which is scanned in four separate lines corresponding to spectral ranges 0À5 Á to 0À6 Á, 0À6 Á to 0À7 Á, 0À7 Á to 0À85Á and 0À85 Á to 1À0 Á. The lines may be scanned successively by a single electron beam or simultaneously by four beams. Preferably the electron beam (27), Fig. 7 (not shown), scans beyond the end of the image so as to traverse a screen area containing two circular scanning marks 281, 282 symmetrically located with respect to the image of one of the spectral ranges. If the beam is incorrectly aligned the asymmetrical voltage pulses resulting from scanning these marks actuates a regulating system (not described) to restore alignment. In a further embodiment four reflecting strips are provided, directing image regions to four vidicons, each image region being spectrally spread, as previously. Preferably the four vidicons scan successively the image regions in the first spectral range, then scan successively those in the second range, and so on. The main image forming lens may be replaced by a Cassegrain mirror lens, with a negative intermediate lens. Successive strips 4 of the subject are scanned as a result of the forward motion of the satellite and/or of its rotation. Stereophotographs may be obtained by providing two pick-up systems arranged at different angles, the angle between them being a measure of the plasticity of the stereo picture which can be obtained.

Feb. 25, 1932, No. 5644. [Class 97 (iii).] A solid mass of a composition containing a fusible and/or sublimable substance or mixture of substances and a filler is adapted to indicate the temperature of a surface, particularly of an iron or calender for textile operations. In use the mass is applied to and leaves a deposit of filler upon the surface to be tested if the temperature of the latter is above melting or subliming point. Suitable fusible or sublimable substances for the mixture are bismuth tribromide, metallic selenium, potassium pyrosulphite, para-azophenol, 1 : 5-dinitro-naphtha,- lene, anthraquinone disulphonic acid, and anthracene. Substances, e.g. naphthalene in the case of anthracene, may be added to lower the melting point. The fillers, e.g. chalk, Fuller's earth, zinc oxide, or powdered pigments, may be coloured by dyestuffs, such as Lithol Fast Yellow 2G, Sudan 2G, Fast Oil Orange T, Fast Oil Scarlet 2R, Para-chlororthonitroaniline, and 2 : 6-dinitro-4-methylaniline, which sublime and/or change colour about the desired temperature of the tested surface.
