Title: Improvements in or relating to process and apparatus for treating yarns or filaments
IPC: D06P5/13
Filed: 1930-03-14
Abstract: Apparatus for making filaments; distinguishing artificial silk of different physical or chemical characteristics; dye preparations.-Yarns or filaments are subjected to successive treatments comprising the application for identification purposes of a liquid containing a fugitive colouring-matter, i.e. one having no affinity for the fibre, and the application of a lubricating liquid. The treatments may be effected in either order.  The invention is particularly applicable to yarns or filaments made of cellulose esters or ethers and/or to yarns containing such cellulose derivative fibres in association with other fibres such as natural silk, regenerated cellulose silk, cotton, or wool, and includes the application to filaments of the cellulose derivatives continuously with their production, i.e. during their transmission from the spinning cabinet to a winding or winding and twisting device.  The tinting liquid contains a solvent, e.g. water, for the colouring matter and preferably also one or more liquids, e.g. oils or polyhydric alcohols, of higher boiling point, specified liquids being olive oil, castor oil, turkey red oil, glycerol, ethylene glycol, and diethylene glycol. p  In an example the tinting liquid comprises Acid green G, Amacid red 3B, colloidal olive oil, and soft water.  The lubricating agent may be a light mineral oil, e.g. spindle oil, a heavy mineral oil, or an oil of another type, e.g. neatsfoot oil, olive oil, or castor oil.  The treatment may be effected by immersing hanks of yarn first in one liquid and then in the other, or may be applied to yarn passing from one package to another.  In the latter case the yarn may pass over successive rollers or wicks dipping into the liquids, or the liquids may be dripped on to the yarns in transit, or the travelling yarn may dip into the liquids successively.  The process of Specification 325,823, [Class 2 (ii), Cellulose &c.], is disclaimed.

Aerial machines without aerostats; planes, arrangement of; cars.-The planes of an aeroplane or hydroaeroplane having multiple supporting-planes are so arranged and braced that they form a structure having one or more of the planes in compression and the planes above and below them in tension. Figs. 1 and 2 show an aeroplane having a plane a carrying flat forwardlysloping partitions a<5> and end pieces a<7>, between which wires are stretched for supporting central planes c and triangular end planes d. The plane a is therefore in compression. The partitions a<5> are braced by wires b<4>, Fig. 8, to the corners of a fuselage set as shown, which is built up of longerons and diagonal pieces and covered with threeply wood or sheet metal. In an hydroaeroplane, the planes are arranged wholly above the fuselage, two sets having their partitions a<5> arranged #-form being used. Planes, construction of; steering and balancing.-The central planes c can be varied in area and incidence, and the end planes d warped in opposite directions. The plane a is of solid wood, or wood sheathed with metal, or it may be of hollow metal with internal supports. The rear wires d' Fig. 9, of the end planes d are connected to rollers d' running on brackets d<10> mounted on the partitions a<5>. The rollers d<9> are moved simultaneously for warping the planes d by a cord d<1> led over pulleys d<2> to a lever d<3>, Fig. 8, or by a cord d<@> connected through bellcranks d<3> and cords d<4> to the lever d<3>. The rear wires of the central planes c are connected to nuts e, Fig. 12, engaged by screw shafts e<1> mounted on the partitions a<5>. The shafts e are geared to a transverse shaft e<5> having a toothed wheel e<6> adapted to he engaged by a lever c'. The rear edges of the planes c may consequently be raised or lowered by moving the lever c<7>. Each plane c may he composed of two pieces of fabric meeting at the centre and mounted by means of rings upon the stretched wires. The meeting edges of the fabric are connected to an endless cord led over pulleys on the partitions a<5> to a drum on the fuselage, so that the two sections of fabric may be drawn apart to vary the area of the plane. Skids.-Skids a', Figs. 1 and 2, are carried at the lower ends of the partitions a<5>.

Title: Epicyclic change-speed gear
IPC: F16H3/66
Filed: 1952-04-02
Abstract: 716,581. Change-speed gearing. RAVIGNEAUX, P. April 2, 1952 [April 9, 1951; Feb. 29, 1952], No. 8459/52. Class 80 (2) Epicyclic change-speed gearing comprises a first three-element train of which the carrier M<SP>1</SP> is fast with the input shaft M‹, the element P is loose and the element Q is fast with one sun M of a second four-element train with intermeshing planets m, c, the second sun C of the second train being loose and the annulus R meshing with the planets c and being fast with the output shaft R<SP>0</SP>. The element P, the carrier A of the second train and the sun C can be braked at P<SP>1</SP>, A<SP>1</SP> and C<SP>1</SP> respectively and the element P and sun C can be clutched to the carrier M<SP>1</SP> at E and E' respectively. By simultaneously engaging two of these five electromagnetically-operated brakes and clutches, six forward speeds (including direct) and one reverse speed can be obtained. As shown, a second annulus B, which is loose and can be braked at B<SP>1</SP>, engages the planets m, whereby eight forward speeds and two reverse speeds can be obtained. The elements P, Q may both be suns, in which case stepped planets are used. As shown, however, element P is a sun and element Q an annulus, with intermeshing planets, so that the first train acts as a reducing train. Alternatively, single planets may be used, in which case the first train acts as a multiplying train. The clutch E may act between carrier M' and element Q instead of between carrier M' and element P. Specification 471,394 is referred to.

Title: Improvements in and relating to electron discharge apparatus for producing modulatedelectric currents
IPC: H01J31/04
Filed: 1949-03-29
Abstract: 701,032. Microphones &c. WTLLS, H. G. March 27, 1950 [March 29, 1949], No. 8509/49. Class 40 (4) [Also in Group XL (a)] Cathode ray apparatus for producing modulated electric currents comprises means for deflecting the beam over two anode members arranged edge to edge, wherein the juxtaposed anode edges are formed' with intermeshing serrations or undulations having oblique or curved faces so as to obtain high sensitivity. The deflecting means may comprise an electrostatic member coupled to a diaphragm or functioning as a diaphragm for receiving sound waves, or coupled to a moving body. In a further modification the electrostatic or electrodynamic means usually employed for focussing the stream may be coupled to the diaphragm or moving body. Particular applications are to microphones and electrical pick-ups such as radiogram pick-ups or pick-ups for detecting movements of parts of a structure under load or subject to vibrations or temperature changes. The device can be used to operate a loud-speaker direct. In the device illustrated, the envelope 1, Fig. 1, is of flat rectangular form and has directly or indirectly heated cathode 2, parabolic negative " reflector " electrode 18, beam forming and concentrating electrodes 10, 16 comprising one or more plates and rectangular frames respectively for forming a ribbon beam, main anodes 3, 4 and an auxiliary centralising anode 19. Two negatively biased " deflector " plates 21, 22 connected by a mechanical coupling 23, are coupled to the diaphragm or other movable body by coupling 24. The plates 21, 22 are thus oscillated up and down and this is stated to vary the current in the output transformer 7, 8. The Provisional Specification states in addition that the deflecting means may be a coil instead of a plate or plates. The deflecting means is arranged as near as possible to the cathode. The movement of the deflecting means may be modified to assist in producing a desired wave form. The deflecting means may be driven by a vibrator or motor or, alternatively, instead of moving the deflecting means, an alternating or varying potential may be applied thereto.

Filed: 1940-05-11
Abstract: 539,720. Road-vehicle suspensions ; vibration damping ; mounting motors. ARMSTRONG SIDDELEY MOTORS, Ltd., and TRESILIAN, S. S. May 11, 1940, No. 8513. [Classes 108 (ii) and 108 (iii)] [Also in Group XXXI] A method of damping a motor-vehicle suspension consists in mounting a mass on a stationary part of a road-wheel assembly for up-and-down movement against a resistance, for damping the wheel in its up- and-down movements relatively to the chassis-frame and in addition providing a separate damping means to act in a similar way on the chassis-frame, to damp the latter against pitching and bumping. The stationary part may be the brake anchor plate 11 on which is secured a vertically-arranged cylinder 12 housing a piston 13 of appropriate mass which reciprocates above a supporting spring 14. An upper return spring 15 is provided. The two ends of the cylinder are filled with fluid, preferably at atmospheric pressure, and the ends communicate by way of a bleed hole 17 in the piston. The piston, instead of itself constituting the appropriate mass, may be connected to an appropriate mass. The amplitude of vibration of the piston 13 may be greater than the amplitude of the wheel when bouncing. The resistance may involve mechanical friction means. The chassis frame 28 may be damped by mounting thereon a cylinder 27 comprising a piston 25 which supports, via a piston rod 21, the front end of the power unit 19A. The cylinder 27 has a fluid reservoir 33 communicating with the liquid inside the cylinder by a valve 34. A torque-reaction damper 22 is secured to one of the chassis longitudinals by means of a bracket 23 and has its movable element linked to a trunnion 24 extending forwardly from the power unit well below the rocking axis of the latter. Some part of the rear of the vehicle, e.g. the fuel tank, spare wheel or luggage boot, may be supported for up-and-down movement relatively to the chassis-frame against a resistance.

Abstract: 453,920. Hedge - cutting machines ; lawn-mowers. LLOYDS & CO., LETCHWORTH, Ltd., and LAWRENCE, J. P., Pennsylvania Works, Letchworth, Hertfordshire. March 20, 1935, No. 8725. [Class 6 (ii)] A hand-carried powerdriven clipper comprises a rotary-blade cutter of high-speed impact type and a pronged guard plate mounted at the back of the cutter and formed in parts which are detachable from one another and are complementary in the sense that the prongs, as regards their number, are distributed between them, so that the clipper may be adapted for cutting hedges or grass. The clipper may comprise an electric motor 1 with a balanced two-bladed cutter 2 removably connected to its shaft through a slipping clutch. A dished guard plate detachably connected to the motor behind the cutter 2 is provided with prongs or teeth for guiding the twigs &c. into the path of the cutting edges of the cutter, which cutting edges sweep over an area radially beyond the periphery of the guard plate. This guard plate is composed of two complementary parts 3, 4, which are interchangeable with similar parts having different arrangements of prongs. The part 3 is used alone for grass cutting and may have three front prongs 7, Fig. 2, six rear prongs 8, and two pairs of side prongs 9, 10. Some of the rear prongs 8 form downwardly turned hooks to protect the cutter as it is drawn backwards. For hedge cutting the complementary annular part 4 having teeth 11, 13, 14, 15 is bolted on the part 3. The crosssection of the dished guard plates is such that there is a minimum of area around the edge lying in a plane substantially parallel to the plane of rotation of the cutter. In order that the tool may be used for trimming lawn edges, the handle socket may be connected to the motor casing by a universally adjustable mounting comprising a clamping strap 20, Fig. 6, having a yoke 23 engaging the socket 26 and pivotally and adjustably connected to the strap by fixing bolts 24 and nuts 25.

Filed: 1958-03-19
Abstract: 850,412. Making sliding clasp fastener chains. YOSHITA, T. March 19, 1958, No. 8813/58. Class 83 (2). Apparatus for making sliding clasp fastener chains in which tape, to which the teeth elements of the chains are to be secured, is fed continually includes means for regulating the input of teeth elements so that chains are produced having no teeth over predetermined lengths thereof. A shaft 48, Fig. 10, drives means for feeding teeth to tape being continually fed through the machine. The shaft 48 is driven from a crank by a link 51, swinging arm 49, pawl 46 and ratchet-wheel 47 on the shaft 48. The pawl 46 is disengaged from the wheel 47 for adjustable periods, to stop the feed of the fastener teeth so that portions of tape having no teeth affixed thereto are formed, by a solenoid 43 actuated by a switch 32, Fig. 7, under control of plungers 22, 23 depressed for the adjustable periods by arcuate graduated bars 18, 19 secured to the faces of a graduated gear-wheel 14. The wheel 14 is rotated by a toothed shaft 12 rotated in one direction by a gear 8 driven directly by a gear 4 driven by a shaft 1 connected to the crank-shaft of the machine, and in the other direction by a gear 9 driven through gears 5, 7 from the gear 4. The wheel 14 is rotated on a feed-screw 17 so that it moves axially until a stop 28 thereon abuts a stop 34 to stop the wheel, this causes a key 10 to be forced radially from a V groove in the gear 8 to a V groove in the gear 9 so that the wheel 14 now rotates in the reverse direction and moves along the screw 17 until a plate 29, Fig. 8, on the wheel 14, hits a stop 33 on a member 25 to cause reverse motion once more. The plunger 23 and stop 33 are adjustable by a screw 30 and the bars 18, 19 and plate 29 are also adjustable.
