Abstract: 864,869. Coating with metals. COMMONWEALTH ENGINEERING CO. OF OHIO. March 12, 1958, No. 7990/58. Class 82(2) [Also in Group XV] Printed circuits or the like, e.g. printing matrices, are made by controlling a source of heat to conform to a predetermined pattern, positioning a backing member over the source of heat and heating areas of the upper surface of the backing member from such source to above the decomposition temperature of a gaseous compound of a selected metal, and exposing the said surface to the gaseous compound to deposit metal on the heated areas thereof. As shown in Fig. 1, a gas chamber 10 is provided, in which a positivelydriven endless belt 16 is caused to circulate around drums 17 and 18, the drum 17 being driven by a motor 23. A further endless belt 40, circulating around rollers 45 ,46, enters and leaves the chamber 10 through slots 41, 42, respectively, and is positively driven at the same speed as the belt 16 by the motor 23. Rollers 26 are biased by springs 27 against the upper flight of the belt 16. Grids 29, made of metal of a high electrical resistance, and forming the pattern to be reproduced, are attached to the belt 16 by clamps 36 (Fig. 5) which have depending arms 37 in sliding contact with conductors 38, which are connected to a source of electrical energy, for heating the grids. The belt 40 has spacing members 50, between which non-conductor backings 56 are fed. Volatile metal compounds, e.g. carbonyls of iron, nickel and zinc are vaporized in a generator 52 and circulated through the chamber 10 by means of conduits 53 and 54. The grids 29 heat corresponding portions of the backings 56 to the decomposition temperature of the metal compound, and the metal is then deposited on the backings in the form of a pattern. A sheet of glass may be interposed between the belts 40 and 16, to prevent metal from being deposited on other portions of the appartus. In a modification, Fig. 8, a battery of infra-red lamps 65, is provided, above which is a heat-conductive sheet 68, e.g. of aluminium. Photographic likenesses on gelatine plates 84 on which are positioned films of vinyl plastic 85 are carried by the belt 69 into the treatment chamber above the lamps 65, and a gaseous metal compound is introduced. The non-shaded portions of the film become heated and metal is deposited thereon.

Patent GB-568258-A (GB)
Title: Process for treating cellulose with formaldehyde
Filed: 1942-06-15
Abstract: Filaments, yarns, flocks, fabrics, films, or other structures made of natural or regenerated cellulose are rendered resistant to swelling by treating them with formaldehyde in the presence of large quantities of relatively concentrated solutions of strong acids which do not exert any parchmentizing effect under the conditions of the treatment, and continuing the treatment at least until the cellulose no longer dissolves in the usual cuprammonium solutions.  The cellulosic materials may be impregnated with an aqueous solution of formaldehyde and then exposed to the action of the acid solution, with or without an intermediate drying step, or they may be treated with an aqueous solution containing formaldehyde and acid.  Natural or artificial staple fibres in flock or yarn form may be treated with a mixture of formaldehyde and acid in a centrifuge.  Fabrics may be treated while their dimensions are fixed by a stenter.  They may be forwarded through the acid solution by means of rollers or selvedge clips or clamps. The treatment may be associated with the production of artificial filaments, e.g. formaldehyde may be added to the spinning solution and a relatively concentrated acid coagulating bath may be used, or the spinning solution may be extruded into an aqueous solution of formaldehyde and acid.  The treatment may be applied at a later stage to the filaments, spun cakes or other packages. Instead of formaldehyde, trioxymethylene or hexamethylene tetramine may be used.  The acid used may be sulphuric, hydrochloric, phosphoric, or trichloracetic acid, or a mixture of these.  A solution of a strongly acid salt such as an alkali bisulphate may be used.  With sulphuric acid, the concentration may correspond to 40-45 DEG  Baum<\>ae, and with hydrochloric acid it may correspond to 17 DEG  Baum<\>ae.  The reaction period may vary from 1 minute to 1 hour at room temperature, and from 5-20 seconds at 70 DEG  C. with sulphuric acid of 40 DEG Baum<\>ae.  Examples describe the treatment of viscose cr<\>zepe de chine fabric, mercerised cotton voile, cotton batiste, staple fibre flock, viscose thread, mercerised cotton twist, and cuprammonium artificial silk in hanks.  The treatment increases the affinity of the cellulosic materials for dyestuffs.

IPC: C08G63/48
Filed: 1961-03-07
Abstract: A method of making drying oil modified alkyd resins comprises subjecting a drying oil to acidolysis with a polybasic acid, and reacting the acidolysis product with a polyol and a vinylidene compound.  The acidolysis product may be reacted first with the vinyl compound and then with the polyol, or may be reacted simultaneously with the vinyl compound and polyol.  When the polybasic acid comprises o-phthalic acid the acidolysis product is preferably treated first with a substantial portion of the polyol, and then with the remainder of the polyol and the vinyl compound.  The drying oil may be linseed, soya or dehydrated castor oil.  The polybasic acid may be a phthalic acid or phthalic anhydride, optionally with up to 10% of fumaric or maleic acid. The polyol may be glycerol, pentaerythritol or trimethylol propane.  Specified vinyl idene compounds are styrene, vinyl toluene, acrylic and methacrylic esters such as methyl methacrylate, and mixtures of vinyl toluene with acrylonitrile. Reaction with the polyol and vinyl compound may be effected under reflux using e.g. styrene or an inert solvent such as xylene as entrainment solvent.  Reaction with the vinyl compound may be effected in the presence of initiators, e.g. benzoyl peroxide and di-t.-butyl peroxide, and chain transfer agents, such as mercaptans and dipentene.  Examples describe the preparation of reaction products from linseed oil, isophthalic acid and vinyl toluene with (I) pentaerythritol and (II) glycerol; and a mixture of soya bean oil and dehydrated castor oil with phthalic anhydride and glycerol and (III) styrene and (IV) styrene and acrylonitrile, and with (V) isophthalic acid, glycerol and methyl methacrylate.

Abstract: 1465204 Fluid pressure switches GIRLING Ltd 26 Feb 1974 [17 Jan 1973] 8714/74 Addition to 1312614 Heading H1N In a differential pressure switch actuated by a double-acting piston and sleeve assembly 17, 18, Fig. 1 in which the switch actuator 22 extends radially towards an annular camming recess 21 of the assembly, a ball bearing 40 is interposed to reduce friction at the camming surface. Inward axial movement of the sleeves 17 towards each other is limited by stops 16 so that in the event of a pressure failure at one end, the piston 18 moves towards that end together with the sleeve 17 at that end. On restoration of the pressure the piston assembly is centralized due to the pressure at the restored end acting on both the piston 18 and the sleeve 17 while away from its stop 16 against the action of the pressure at the other end of the piston 18 only since the sleeve 17 at that end is against its stop. In a modification the sleeves 17, Fig. 2 abut each other at their inner ends and on an 0-ring 43 on the piston 18 and also abut stops 16 on the housing. A groove 42 for the ball 40 is formed at the abutment between the sleeves, whereby on movement of a sleeve the ball 40 is free to move radially of the piston 18 to actuate the switch.

Title: Improvements in and relating to textile winding machines
Inventor: MACKIE JOHN KAY PRINGLE
IPC: B65H54/14
Filed: 1955-03-29
Abstract: 823,041. Winding yams; stop mechanism. MACKIE & SONS Ltd., J. March 15, 1956 [March 29, 1955], No. 9143/55. Class 120(2) A stop motion for a cop or roll winder comprises a stopping mechanism which is brought into action on breakage or running out of the yarn by a detector lever pivotally mounted on the machine frame between its end and carrying at one of its ends yarn tensioning means, the detector lever being normally held in a position not actuating the stopping mechanism, by reason of the frictional pull of the yarn on the tensioning means. In the embodiment shown a winding spindle 10 is driven by a rope 18 through a pulley 20 fast on the spindle and lying alongside a loose pulley 22. A shift lever 24 for shifting the rope from one pulley to the other is pivotally mounted at 26 and has a downward extension 28 which forms a detector lever and carries a yarn tensioner 30. The yarn  12 passes over a guide 34 downwards through the tensioner 30 to a traverse arm 14. The shift lever carries a brake member 36 for bringing the spindle to rest. When the spindle is rotating and yarn is being wound on the cop the friction between the yarn and the tensioner causes the lower end of the detector to be pulled towards the spindle and the shift lever and the brake are held inoperative. If the yarn breaks the detector unit swings about the pivot 26 so as to shift the rope on to the loose pulley and stop the spindle. To restart winding after piecing up the detector lever is pushed towards the spindle so that the brake is removed from the spindle and the driving rope shifted on to the fast pulley. In the case of a roll winder the stop motion raises the head carrying the roll of yarn out of engagement with its driving roller.

Abstract: 250,935. Vaugeois, J. G. April 14, 1925, [Convention date]. Radio active s u b - stances and preparations thereof.-In an apparatus for rendering liquids radio-active, the radioactive material is separated from the liquid by an air chamber in such a manner that the emanation is able to reach the liquid. As shown in Fig. 1, the radio-active material e is contained in a tube c fitted with a porous plug d and supported in a larger tube a. The tube a is fitted with a porous plug b at its open end and is supported from the stopper g of the vessel containing the liquid. In use, radium emanation diffuses into the liquid through the plugs d, b, but the liquid is kept out of contact with the radioactive material by the air in the tube a. In the form shown in Fig. 2 the radio-active material is contained in a tube a closed by a porous plug b and supported above the level of the liquid by the stopper g. The construction shown in Fig. 2 may be modified by giving the lower end of the tube a a capillary form or by fitting it with a valve constructed so as to open only when the container is in a vertical position.

Abstract: 344,681. Lowering the ring rail and stopping ring spinning &c. machines when the set is completed. RUSHTON, J. L., Kay Street Works, Bolton. March 25, 1930, No. 9438. [Class 120 (ii).] In ring spinning, doubling, and like machines, wherein a locking-member such as a plunger engaging a chain block or other part of the building-motion is automatically released on the completion of a set to allow the ring rail to fall under control to its lowest position for doffing, a cam operatively connected with the building-motion effects the release and resetting of the locking - member, the descent of the rail is controlled by a weight operatively connected to the chain block or other part engaged by the locking-member, and the machine is stopped by means actuated by the descending ring rail. The building-motion to which the invention as described is applied comprises a chain 20, which is connected to a block 19 operated from the building-lever and to the lifting-pokers, and is anchored to a block 21. The locking-member comprises a plunger 37 which normally engages a stop on the chain block 21, and is released by a lever 32 connected to a sleeve 36. A spring-controlled plunger 48 engages the sleeve 36 and is arranged so that, when the end of the sleeve is moved into contact with the head of the plunger it snaps over a double wedge-shaped part on the sleeve to remove the plunger from the stop on the chain block 21. The lever 32 is operated by a cam 29 on the shaft of the block 19, and is reset by a cam 30 on the same shaft when the building-motion is reset. The descent of the ring rail is controlled by weights 56 connected to pulleys 60 on a shaft 59 geared with the shaft 41 of the block 21. A cam 65 on the shaft 59 is arranged to release a bar 68, when the shaft 59 is rotated during the fall of the ring rail, so that it is drawn longitudinally by a spring 71 and moves the belt-shifter 75 to transfer the driving-belt of the machine to the loose pulley. A slot 73 in the bar 68 permits the apparatus to be reset without moving the belt back to the fast pulley, this being subsequently done by hand. The cam 65 may be adapted to control clutch mechanism or an electric switch according to the nature of the drive.

Roundabouts.-Motor-driven cars H are propelled round an endless track D on a platform C of a roundabout having a surface which is partly undulating and partly horizontal, and are mounted so as to be capable of lateral movements with respect to the track, and variable speeds of travel. The straight portions X, X<1> and X<2>, X<3> are undulating, as shown in Fig. 7, while the end portions of the track are horizontal. A guide-rail E is provided at a higher lever than the track D and running round this rail E is a series of undercarriages G provided at one end with runners F, F<1> and at the other with a pair of wheels I, I<1> which have two diameters, as shown in Fig. 3. The rear wheel I<1> is driven by a chain J<1> from a motor carried by a car H, which is pivoted at its fore end about a vertical pin J carried by the undercarriage G<1>. While traversing the undulating sections of the track, the smaller diameter of the wheel I<1> engages the track, which is in the form of an open channel, but on reaching the ends, the larger diameter engages a rail D<1> placed in the bottom of the channel, thus increasing the speed of the car H. The cars are connected together by jointed flexible rods Q, which permit of the acceleration of one car independently of the other. Lateral movements of the car H on the track are caused by the steering wheel K operating the bar L which carries the rear castors O.
