Title: Improvements in or relating to the manufacture of artificial filaments, fibres, threads and the like filamentary products
IPC: D01F4/00
Filed: 1947-05-22
Abstract: Artificial filaments, fibres, threads and like products are produced from viscous alkaline peanut globulin solutions by extrusion from a multi-hole spinneret into an acidic saline solution and, if desired, passed into one or more non-swelling saline solutions prior to insolubilization, all saline solutions being at a temperature less than 40 DEG  C., and are then led on to one or more supporting surfaces against which they are pressed with substantial stress, the process being characterized in that at least the saline solution preceding the first such supporting surface includes therein a cationic surface active agent.  The latter may be an alkyl quaternary ammonium halide such as cetyl trimethyl ammonium bromide or an alkyl pyridinium halide such as cetyl pyridinium bromide.  About 0.1-2 per cent on the weight of the liquor may be used.  In an example an aged solution of peanut protein (28 per cent protein, 1.45 per cent sodium hydroxide) is extruded through a 500-hole spinneret into an aqueous bath containing 3 per cent sulphuric acid and 19 per cent sodium sulphate at 28 DEG  C.  The filaments are then passed into a nearly saturated sodium chloride bath containing 0.5 per cent cetyl trimethyl ammonium bromide at 20 DEG  C.  The filaments so produced are collected in hank form on a pair of rollers, on one of which the hank is allowed to drain while hanging under its own weight.

Title: Improvements in or relating to the production of photographic sound records
IPC: G11B7/00
Filed: 1934-05-10
Abstract: 439,631. Optical sound-recording and re-recording apparatus. KOLB, O. K., 39, Beverley Court, Wellesley Road, Chiswick, London. May 10, 1934, No. 14106. [Class 40 (ii)] An optical sound-recording or re-recording system is adapted to produce simultaneously two or more substantially identical records by means of a single electro-optical sound recording or re-recording instrument, such as a light valve or modulator, galvanometer or oscillograph system, which controls a plurality of light beams directed to and focused on the desired number of sound track spaces located on two or more separate or separable films each adapted to serve either as a negative for printing positives therefrom, or as a sound record film for direct sound reproduction. As shown, light from a source 10 passes through a lens system 11, apertures 12<a>, 12b in a mask 12 and a lens 13 on to an oscillograph mirror 7<a> which is actuated for direct recording purposes by currents from a microphone 27 and amplifier 6 or for re-recording purposes by currents from a photo-electric cell 5 influenced by a master film 1. The amplifier may be provided with known volume and tone correction devices. The light beams reflected from the mirror 7<a> pass again through the lens 13 causing images of the apertures 12<a>, 12b to be formed on the slit diaphragms 14, 15 arranged in front of lenses 16, 17. The divergent beams after being rendered parallel by double reflection in prisms 18, 19 fall on objective lens systems 20, 21 and are focused so as to produce images of the slits in diaphragms 14, 15 on the two half films 22, 23 which are combined in a single film strip 24 adapted to be divided ultimately along the centre line 24<a> and provided with two sets of sprocket feeding perforations 22<a>, 23<a> and with two sound tracks 22<b>, 23b. When the records are used as negatives, the perforations in the film serve to assist its passage through the positive printing and after processing devices before division of the film. A multiple series of cinematographic images can also be impressed on the film before the processing and division of such combined sound films is performed. According to a modification, two separate exciter lamps may be employed. An observation microscope system comprising a prism 25 and eyepiece 26 may be inserted in the path of one or other of the light beams 8<a>, 9<a>. The various optical elements may be separately and independently adjustable. Specification 393,610 is referred to.

Title: Improved ink-ribbon mechanism for typewriting-machines
IPC: B41J33/40
Filed: 1928-05-14
Abstract: 311,102. Alexander, r. May 14, 1928. Ink-ribbon mechanism.-Automatic feed-reversal mechanism comprises rocking discs connected to feed pawls and coupled alternately to a rocking disc operated by the universal bar. An adjustable-throw vibrator may also be operated by the universal bar. In the mechanism shown in Figs. 1, 3 and 5, ratchet-wheels 7 on the spool-spindles 6 co-operate with pawls pivoted on slides 10 having apertures for engaging levers 11 which are connected by links 27 to arms 31 on sleeves 32 mounted loosely on a rock-shaft 33. The slides engage levers connected to returning-springs, and the tails of the pawls abut on the ends of slots formed in adjustable plates. The sleeves 32 are formed with discs 35, 38 abutting on a disc 41 which is secured to the rock-shaft and is provided on opposite faces with balls 43, 42, Fig. 5, adapted to engage cups 36, 37 on the disc 35, and cups 39, 40 in the disc 38 respectively. A finger 79 pivoted on the disc 41 engages slots in the discs 35, 38. The disc 41 is provided with a fork 44 engaging a rocking arm 46 operated by the universal bar 48. The levers 11 associated with the winding and unwinding spools are engaged with and disengaged from their slides, the corresponding arms 31 being in the rearward and forward positions. When the end of the ribbon is reached, tension prevents movement of the operative lever and disc 35 or 38, and the movement of the disc 41 and finger 79 reverses the relative positions of the discs and arms, thereby reversing the feed. The balls pass from one cup to another during the movement of the discs. A returning-spring 77 is connected to the disc 35. The vibrator 56 is carried by a lever 54 connected by a link 50 to the rocking arm 46. To permit of colour adjustment, the lever 54 rocks on alternative fulcra 58, 59 secured to a rockshaft 57 connected by linkage 60, 62, 63 to a ribbon-key lever 64 which can he locked by means of a pivotel catch 73. To facilitate assembling, some of the above-mentioned links and levers are provided with open slots for engaging their pivots or pivotal connections. To permit of access to the mechanism, the tabulator bar 82 and the platenshift devices 85, 86 are detachable, and the spool spindles 6 are supported on a detachable framemember B.

Title: Improvements relating to Change Box Motions for Looms for Weaving.
IPC: D03D43/00
Filed: 1916-10-09
Abstract: 108,941. Butterworth & Dickinson, and Prior, A. Oct. 9, 1916. Change-box motions.-In a change-box loom, an indicator operates in conjunction with a dial or plate bearing numerals arranged in predetermined order and placed opposite to, between, or in line with, the needles or other card or pattern-chain controlled devices, the arrangement being such that, when any one of the boxes is in operative position, the numerals indicated or exposed by the indicator show which needle &c. is to be operated to bring any other box into operative position. As applied to an Eccles boxmotion, an indicator B, Fig. 2, is connected by a rod b to the box lever, and three needles C, C<1>, C<2> are employed in a four-box loom, the needle C effecting a one-box change, the needle C<2> a twobox change, and the needle C' acting on the needles C, C<2>, as shown in Fig. 3. A plate A has vertical rows of numerals over the needles and, at the right side, indicators of the boxes 1 - - 4 and, if desired, of the colours of the wefts used. The numerals are such that, if, say, the box 1 is indicated, the numerals 2, 4, 3 in the first row indicate the box that will be brought into operative position if the corresponding needle C, C<1>, C<2>, respectively, is operated. The plate A may have numerals on both sides and may be moved instead of the indicator; or the indicator may be in the form of a frame with an opening to expose one row of numerals. When two separate needles are moved simultaneously by blanks on a card to effect a change of box, for example when three needles causing two-box, onebox, and two box changes respectively are used for a six-box loom, the box-indicating numerals may be placed in a vertical row between the corresponding needles or in the rows over both needles. A similar plate with a hand-actuated indicator may be used to assist in the preparation of the cards or other pattern surfaces.

Title: An improved resilient wheel
IPC: B60B9/18
Filed: 1920-05-27
Abstract: 146,937. Weston, M. T. July 3, 1919, [Convention date]. Spring wheels with continuous outer rigid ring and pneumatic hubs and cushions.-The axle of a spring wheel carries arms 1 on which are pivoted links 2. The cuter ends of the links 2 are pivoted at 3 to links 4 on a journal 12 mounted on brackets 10 on the outer rim 5, so that the pivot 3 is intermediate of the journal 12 and pressure rollers 20 at the ends of the arms 4. A pneumatic tube 37 with a cover 27 is arranged between the link mechanism and a rim 7 carried by the outer rim 5. The cover 27 carries plates 23 connected to anchor plates 34 by chain belt connexions 33, flexible radially but transversely inflexible. The plates 23 provide a bearing-surface for the pressure rollers 20 and resist the displacement of the axle to an eccentric position. The tyre cover is closed round its outer periphery by hooks 30, Fig. 20, engaging a circumferentially-disposed wire 32. The inner tube 37 is provided with pads 38, Figs. 2 and 10, in radial alinement with the rollers 20 to take up stresses on deflation, and these are held in an operative position by an insertion 39 between the rim 7 and the tyre, of which the thickened portions support the pads 38 as shown in Fig. 2. This insertion may be of the form shown in Fig. 16, in which a metal band 41 is corrugated at 42 varying in depth according to the thickness required. The corrugations admit air for cooling the parts. The pneumatic tube is shown in Fig. 2, having narrow portions 27a which register with the anchor plates 34, and wide portions 27<b> which contain the pads 38 and register with the pressure rollers 20. The respective cross-sections are shown in Fig. 1, being flattened to allow a large effective pressure from a relatively small pressure in the air tube. Packings 9<1>, 43 are arranged between the rim 5, and the side covers 52, 44 respectively. A packing 48 bears upon a brake drum connected to the axle. Ports 80, 81 supply communication with the atmosphere, a partition 83 preventing the entrance of water. In a modification, the pressure plates 23 and the anchor plates 34 are not connected by a band 33, the pneumatic tube being circular in cross-section at the intermediate points. In another modification, the tyre cover may be thicker where it registers with the rollers 20.
