Title: Spreading device for fertilisers
IPC: A01C15/18
Filed: 1955-05-12
Abstract: 793,259. Manure distributers &c. VAN DER LELY N.V., C. May 12, 1955 [May 13, 1954], No. 13790/55. Class 6(1). A manure distributor, of the type wherein one or more hoppers 24 feed material to endless belts 21, 22 extending transversely to the direction of travel so that the material is carried transversely for various distances and is discharged over one lateral edge of each belt, is characterized in that this edge of the belt is bent downwardly at the point of discharge so that the carrying surface, of the belt tapers longitudinally outwardly. The machine comprises a chassis 4, 5 extending forwardly to a towing-connection 7 and rearwardly to wheels 1, 2 which drive a shaft 3 through ratchetclutches. The shaft 3 drives gearing in a gearbox 14 from which two output shafts 12, 13 rotating oppositely at the same speed transmit power to the driving shafts 10, 11 of the two belts 21, 22. The belts run over rollers 35, 36 (Fig. 3) carried by stub-shafts 34 arranged along the length of transverse beams 17, 18, the beams being hinged, as at 28, so that their outer ends 29 may be folded up, for transport. Each stub-shaft carries a grooved roller, the undersurface of the belt having ribs 39 which enter grooves 36 in the roller and the upper surface having longitudinal channels which carry the fertiliser. Each roller has one fewer section 35 than its predecessor so that the forward edge of the belt is unsupported and hangs down vertically, this action being accentuated by the outer end of the belt being passed around a vertical roller 45 on the end of the beam. Adjacent to the forward edge of each roller, a scraper 48 bears on the belt to discharge fertiliser from the corresponding channel and at the rear edge a flanged roller 42 bears on the belt to prevent its accidental removal from the rollers 35. In a modification, a single endless belt is used, passing around vertical rollers at its outer ends and over horizontal rollers at intermediate points. The scrapers may comprise wheels in oblique staggered formation.

Filed: 1925-05-27
Abstract: 257,332. Rogers, R. H. May 27, 1925. No Patent granted (Sealing fee not paid). Moulding walls in situ; scaffolding.-Shuttering sections for casting walls in situ are positioned and held in vertical alignment by means of uprights 1, Fig. 1, consisting of aligned vertical superposed planks, or by pre-cast pillars 34, Fig. 3, and consist of angular shaped members 2 having strengthening ribs 8 and also means on their upper faces for retaining superposed members in vertical alignment. The lower sections are adapted to be removed without removing the upper sections and are placed above the upper sections for continuing the erection of the wall. The aligning means for superposed sections is in the form of a strip 5 of iron or wood extending along the whole length of a section and spaced from the front edge a distance equal to the thickness of a section. The strips 5 may be detachable. In the case when temporary uprights are employed, the sections are spaced at the required distance apart by means of distance-pieces 3 fitting between the sections and the uprights, and held in position by plates 4 secured to the distance-pieces and also, if desired, to the uprights. Metal straps or cords may be employed to hold the shutters in position. The inner faces of the shuttering sections are provided with vertical triangular projections and horizontal projections 7, which are so arranged as to give the surface of the finished wall the appearance of a wall formed of concrete blocks which break joint. In forming a sill, a water groove is provided in its undersurface by means of a strip of suitable material placed on the corresponding surface of the moulding section. At corners, the ends of the shutters are arranged to overlap. The uprights 1, Fig. 1, are formed of planks connected in vertical alignment by means of gas pipes or bars 22 which are held in grooves 21 by clamps 23. Tie-bars 24, 26 hold adjacent uprights in correct position. Brackets 27 for securing platform boards are secured to the uprights. In the case of pre-cast pillars, Fig. 3, such members have holes for the reception of bolts 35, and distance-pieces 36, planks 37, and sliding wedges 38, hold the shutters 2 in position. The first Provisional Specification describes the aligning member 5 as of angle-iron form.
Patent GB-591712-A (GB)
Title: Improvements in the finishing of textile fabrics
IPC: D02G1/18
Filed: 1945-05-10
Abstract: A textile fabric containing wool fibres and cellulose acetate staple fibres is subjected to the action of an aqueous solution of an organic substance which is a shrinking agent for the cellulose ester or ether.  The treatment results in the consolidation of the fabric and in an increase in the proportion of wool in the surface of the fabric.  The treatment may be utilized in conjunction with other treatments such as milling, or as described in Specification 591,708, with a raising operation.  The material may be milled while wetted with an aqueous soap solution or dilute sulphuric or other acid either before or after the treatment with the softening agent for the cellulose derivative fibres.  If desired, the material may be milled while wet with the softening agent.  The softening agent may be an aqueous solution of acetic acid or other lower fatty acid of 30-50 per cent strength.  Solutions of formic, propionic or lactic acid, or of dioxane, diacetone alcohol, glycol monomethyl ether acetate, acetone, ethylene - methylene ether, ethyl lactate, phenols, cresols, chloracetic acid, or glycollic acid may be used.  Woven or knitted fabrics may be treated and the wool and cellulose derivative fibres may be associated in any desired manner.  In an example, a fabric knitted from a spun yarn from a mixture of equal parts of wool fibres and cellulose acetate staple fibres is scoured and soaked in a solution of acetic acid.  The material is then rinsed, centrifuged, dried and ironed.  The treatment results in shrinkage of the fabric which is then resistant to further shrinking.  Upon dyeing the material with a blue wool dye such as Coomassie Brilliant Blue F.F.S. and a red dye for the cellulose acetate such as 1-methylamino-anthraquinone from a neutral bath, the resulting fabric is predominatingly blue due to the high wool content at the surface of the material.  In another example, a woven fabric consisting of warp and weft yarns spun from wool and cellulose acetate staple fibres is steeped in aqueous acetic acid, drained, milled for 3 hours, rinsed in water and dried.  The material is shrunk and consolidated and the surface contains a high proportion of wool. Local effects may be obtained by printing, stencilling or otherwise locally applying the softening agent to the material. In an example, a fabric knitted from a yarn containing wool fibres and cellulose acetate fibres is printed in stripes with aqueous acetic, formic or lactic acid.  It is then washed and neutralized. If the material is then dyed with a blue acid wool dye, the printed portions have a deeper shade of blue than the unprinted portions due to the preponderance of wool in the surface of the former.  Contrasting effects may also be obtained by dyeing the printed material with Coomassie Navy Blue 2RNS and 1-methylamino-anthraquinone. Specification 380,504 is referred to in the Provisional Specification.

Title: Improvements in electric lamp sockets provided with cut-outs
IPC: H01R33/96
Filed: 1931-05-14
Abstract: 365,931. Electric lamp holders. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Crago, H. R. ; 840, De Camp Avenue, Schenectady, New York, U.S.A.) May 14, 1931, No. 14298. Convention date, May 15, 1930. [Class 39 (ii).] A lamp holder adapted for use with lamps connected in series is provided with an electromagnetically operated cut-out which closes a shunt circuit when the lamp filament is ruptured, the cut-out being located between spring contact arms 25, 26, Fig. 1, which are connected by screws 23, 24 respectively to the screw-threaded socket shell 19 and the central contact 22 of the lamp holder. The contact arms 25, 26 are engaged between spring contacts 14, 15 connected to terminal posts 16, 17 on the insulating-base 11 of a series lighting unit of known type. The electromagnet comprises a winding 35, Fig. 4, on an insulating spool 36 riveted to the spring contact 25, the ends of the winding being connected directly to the contacts 25, 26. A spring plunger 38 mounted in an axial bore of the spool is urged outwardly by a light spring 39, so that its end 38a engages with an offset member 43, Fig. 2, at the end of a spring contact 40 secured at 41 to the spring contact 25. In this position a contact ear 42 on the member 40 is held apart from a contact ear 44 on the spring contact 26. The resistance of the winding 35 relatively to that of the filament is such that the current passing through the winding is negligible. Upon the rupturing of the filament however the increased current through the winding 35 causes the plunger 38 to be pulled inwardly, thereby releasing the contact spring 40 and bringing the contact ears 43, 44 together to provide the shortcircuiting path.

Abstract: 360,818. Looms with stationary weft supplies. BRITISH CELANESE, Ltd., 22, Hanover Square, London, and POOL, W., of British Celanese, Spondon, near Derby. May 9, 1930, No. 14312. [Classes 142 (ii) and 142 (iii).] In looms in which lengths of weft are inserted from a stationary supply, the weft is inserted in the shed leaving an end free and is tensioned during the beat-up. At one or both ends of the shuttle race, which is covered with Bedford cord, there is arranged an attachment 14 in communication with suction apparatus and having an aperture adapted to be opened by a cam 69 to cause the end of weft released by a dummy shuttle 90 to be drawn in and tensioned. Slides in the attachment, also operated by the cam 69, then move to close the opening to the suction device and to grip the thread which is then beaten-up. A cord or lever may be arranged beneath the weft to increase its tension. Sliding cutters also operated by the cams 69 sever the end of weft within the attachment, and the subsequent suction carries such ends into a container. A centre weft-fork 93 is arranged to stop the loom in case of incorrect laying of the wefts from either side of the room. The weft may be laid in hairpin form with one limb in each shed as described in Specification 346,850. According to the Provisional Specification a trimmer knife operated by the lay is adapted to pass through the reed and sever the weft near the selvage.

Abstract: 682,213. Bending. DUBOSCLARD, P. P.M. June 8, 1950 [June 13, 1949], No. 14339/50. Class 83 (iv). A machine adapted to bend a relatively thick metal sheet of uniform or of varying crosssection includes freely rotatable rolls associated with pressure-applying means controlled in a predetermined manner and means for moving each end of the sheet independently of its other end while under pressure from the rolls. The machine comprises a bed having a horizontal flange 19 and a vertically movable beam 28 having reinforcing ribs 35 and upper and lower horizontal flanges 34 and 31 with projections 36 and 37 respectively. Keyed to the flanges 19 are brackets for rolls 23 acting as supports for two lower idle rolls 21 extending across the machine. A single larger diameter roll 26 is similarly backed by rolls 29 mounted between brackets keyed to the flange 31 of the beam 28 which may be raised by means of two hydraulic devices 43 or pressed down by four hydraulic devices 48, the pairs of devices 48 at opposite ends of the beam being separately supplied with fluid so that a greater pressure may be exerted on one end of the roll 26 than on the other. Slidably mounted within the bed beyond the ends of the rolls are carriages 64, each having a bottom rack 87 engaging a pinion 91 and an upper detachable cam 62. Each carriage is coupled to one end of a rod 72, the other ends of which rods are joined by a member 75 to which the work is secured by bolts 78. The two carriages are traversed at different predetermined speeds so that the two sides of the work are drawn or punched between the rolls at different speeds. Rollers 53 bearing on the top of each cam 62 are connected through a bar 57 with the upper projections 36 of the beam 28 and hence with the pressure-applying means 48. A spring 60 relieves back-lash and the differential compression between the bar 57 and an unloaded bar 111 may be utilized to operate a strain gauge indicator. In a modification, Fig. 11, rollers 21 are omitted and the carriages 64 are connected to the opposite sides of a cam block 120 slidable over the bed of the machine and having stops 128 and 129 to position thereon the work 127.
