Title: Improvements in or relating to the distribution of viscous liquid substances in pipes
Inventor: PARR WILLIAM GEOFFREY
IPC: D01D1/06
Filed: 1963-03-22
Abstract: 1,012,501. Spinning composition supply system. BRITISH NYLON SPINNERS Ltd. Feb. 28, 1964 [March 22, 1963], No. 11378/63. Heading B5B. [Also in Division F2] A spinning solution (or melt) supply system (Fig. 1) comprises a supply pipe or manifold M fed with the viscous liquid material under pressure and having successive sections 1-4 of decreasing diameter, and stripping junctions T 1 -T 3  for branch pipes at intervals along the pipe designed to remove an outer annular portion of liquid, so spaced and constructed that the times of transit of the liquid material from the supply pipe inlet to each of the withdrawal positions (P 1 -P 4 ) are at least substantially equal. Thus the extent of thermal degradation of a polymer, e.g. hexamethylene adipamide, withdrawn at each point is substantially the same. Thus, in Fig. 1, the volumetric flow u at each position is the same and is a quarter of that (4u) at the input of the manifold, the dotted lines within the manifold showing the boundaries between the streams flowing to the respective positions. By reversing the direction of flow of liquid through the apparatus, it may be used for providing a viscous liquid material from a plurality of sources of supply to a common outlet. In Fig. 2, a manifold M is connected to a twin branch stripping junction T having three branches B 1 , B 2 , B 3 , the upstream end portion of the smaller diameter pipe of branch B 3  protruding backwardly into the manifold. In Figs. 3 and 4, a manifold M is connected to a single stripping junction T having a branch pipe B. In Fig. 3, division of the stream takes place upstream of the junction, as in Fig. 2, by virtue of the backward protrusion of the inner pipe of the stepped down portion of the manifold. In Fig. 4, division of the stream takes place downstream of the branch B, the outer annulus of the stream of liquid being reversed in direction before flowing down the branch pipe. Figures 5 and 6 illustrate the use of an annular metering slot at the stripping junction leading to an annular plenum chamber C. In Fig. 6 a sufficiently large plenum chamber enables the asymmetric arrangement of branch pipes B 1  and B 2  to be used if desired. Fig. 7 illustrates a four-branch junction. Branch pipes B 1 -B 4  are equal in diameter to the manifold M so that they more than cover the circumference of the manifold at the tapping station T. This overlap is necessary if proper stripping of the entire annulus is to take place by the action of meter pumps extracting an equal flow in each of the branch lines.

Title: Device for folding and inserting liners into folding box shells
IPC: B31B7/46
Filed: 1956-04-16
Abstract: 794,652. Making lined cartons. BALJAK CORPORATION. April 16, 1956 [April 20, 1955], No. 11446/56. Class 18. A machine for inserting liners into cartons comprises plunger and die means for folding up the liner blanks, the plunger having a projectible element for forcing the liner into a carton beneath it, and the die being associated with members for engaging the carton and for preventing infolding of the liner during its passage into the carton. The machine described sets up both carton and liner blanks, the cartons being discharged onto a conveyer for transit to beneath the liner plunger. Carton and liner blanks BB and LB are removed simultaneously from two stacks by a pivoted frame 22 carrying suction heads 18, 19, and deposited across the apertures of the liner and box dies. The blank removing means may be as described in U.S.A. Specification 2,624,249 and Specification 785,183 [Group XVI]. The box forming die and plunger means are as described in Specification 668,523. The liner folding plunger 31, which is connected to a reciprocating head 25 common to the box plunger 33 includes a bottom wall 45 projectible beneath the plunger side walls by lever means 46, 47 operated by a roller 50 striking a part 51, Fig. 2, of the die as the plunger descends. The wall 45 is biased upwardly by springs 57 on tubes 55, the tubes sliding on guide rods 58. Pivoted below the end walls of the die are vanes 70, 71, these being spring biased inwardly to the position of Fig. 7, and being movable between resilient stops 76, 77, 80, 81 by contact with the descending liner. When the liner blank is placed on the die, members 24 on the frame 22 co-operate with elements 59, Fig. 16, on the die to give the corner gussets a preliminary creasing. The frame 22 withdraws and the plunger forces down the blank, the corner gussets folding and passing into corner gaps in the die. Folding rods 65, Fig. 7, turn the gussets onto the liner end walls. Towards the end of the plunger stroke, the vanes 70, 71 commence to be swung downwardly and enter a carton located on the conveyer beneath by a stop 101, Fig. 11, to engage the inside of its end walls. At the same time, the vanes press the liner gussets against the plunger. When the roller 50 strikes the surface 51, the bottom 45 thrusts the liner into the carton. The cartons and linings may be of other forms than those shown. The cartons may be formed by a separate machine (not described). Specification 794,653 also is referred to.

Title: Improvements in illuminating flares
IPC: B63B51/04
Filed: 1946-04-15
Abstract: 610,684. Illuminating-flares. SCHERMULY, C. D., SCHERMULY, A. J., and SCHERMULY, C. April 15, 1946, No. 11470. [Class 9 (ii)] A marine flare device of the kind described in Specification 579,703 has the flare candle 9 located in the upper part of the casing 1, the ignition fuze being led through the casing adjacent its lower end, the device being so weighted and the buoyancy chamber 2 so disposed that on separation of the cover 3 from the casing, the said casing rotates through 180 degrees so that the candle is then in the lower part of the casing and the lighted fuze at the top. The casing 1 having stabilising fins 8 and a buoyancy chamber 2 on to the lower end of which is slipped a cover 3, said cover being secured to said chamber by a soft-solder joint 5, is closed at the lower end by a metal foil disc 7. A metal plug 13 closes the upper part of the casing 1 in which a candle 9 is supported by a spacer 10. the lower end of the candle being closed by a combustible cover 11. Below the buoyancy chamber 2 is a wooden block 14 surrounding the casing 1, the said block having a recess 15 into which fits a metal plate 16 below which is a block 17 having an orifice 18 and passage 19 for an instantaneous fuze 20 communicating with a delay fuze 21 housed in a metal tube 24 and joined to a quick-match 22, itself communicating with the combustible cover 11. The tube 24 passes through the casing 1 and is crimped to the fuze 20 to render the casing 1 water-tight. Inserted in the lower end of the cover 3 is a metal plug 29 having a central hole for the passage of a contact fuze 30, which may be ignited on impact with the water or may be a delay fuze. Arranged between the plug 29 and the block 14 is a metal block 31, spacer plates 33 and a primed cambric disc 32. In the metal block 31 is an annular recess 34 filled with a separating charge 35, the said charge communicating by a length of quick-match 37 in a hole 36 in the block 31, with the cambric disc 32, which is in contact with the lower end of the instantaneous fuze 20. When the device is dropped from an aircraft and the fuze 30 is actuated on striking the water, the flash from fuze 30 ignites the disc 32 and passes thence by instantaneous fuze 20 to the candle 9. The disc 32 also ignites the quick-match 37 and hence the separating charge 35, detonation of which separates the cover 3 from the buoyancy chamber 2, whereupon the block 31 and spacing plates 33- fall away from the casing 1, which then rises to the water surface and rotates through 180 degrees, the gases from the burning candle forcing off the foil disc 7.

IPC: B27J5/00
Abstract: 114,846. Kiellerup, O. Oct. 8, 1915, [Convention date]. Cork, cutting.-In a machine for cutting cylindrical corks, a piece of cork is first secured upon points on a jaw 4, and a preliminary movement of a handle 22 moves this jaw gnadually so that the cork is pressed on to a jaw 8, and further movement of the handle slides the shafts 7, 9 of the jaws to couple the shaft 9 to a continuously rotating friction disk 13 so as to rotate the cork, and at the same time the frame 1 carrying this apparatus is swung to bring the cork gradually up to the rotating cutter 30, Fig. 3. Before inserting a cork, the jaw 4 is retracted against the action of a spring 17 by a fork 19, which is loose on the shaft 21 of the handle 22, engaging a collar 20 on the shaft 7, the fork being moved by a pin controlled by the handle, and pawl 18 retains the jaw in the retracted position. When the handle is raised, a cam x on a plate 23 movable with it gradually raises the pawl 18 while in contact with the fork 19 to permit the initial movement of the jaw 4 by the spring 17, and then raises the pawl clear of the fork to permit the final movements. The frame 1 is pivoted on arms 2, and a face cam y on the plate 23 engages a stop 29 to enable a spring 31 to rock the frame and draw the cork gradually into contact with the cutter 30.

Abstract: 1309931 Reeling and steaming textiles; skein winders CROON & LUCKE MASCHINENFABRIK GmbH 10 March 1970 [25 Aug 1969] 11524/70 Headings D1J and D1L Hanks of yarn are removed from a reeling machine by a stripping ring which surrounds the reel frame, means being provided to move the ring from one end of the frame to the other thus displacing the finished hanks. As described the hanks are displaced on to a shaft of a transporting truck so that they can be conveyed to a steaming machine. As shown in Figs. 1 and 5 the reeling machine has a reel frame 5 carried on a shaft 6 mounted in a bearing 7. The frame members 5' are connected to the shaft by links which enable the diameter of the frame to be increased or decreased. The hank transporting truck 2 consists of a wheled chassis 15 on which is rigidly supported a tube 12. When the hanks 27 are of the prescribed weight, the winding is stopped and the truck 2 is positioned in line with the reeling machine shaft as shown in Fig. 4 with the tube 12 passing through the hanks. The diameter of the frame 5 is reduced by actuating the link mechanism and the hanks are pushed off the frame onto the tube by advancing a stripping ring 29 having inwardly projecting spokes 62 which engage the last hank. The ring 29 is carried by a slide 44 engaging a bar 43 disposed parallel to the frame shaft 6. The hanks are carried on the truck to a steaming machine 3. This machine consists of a casing closable at one end by a door 83 and from the opposite end of which project two vertically spaced perforated steam pipes. The tube 12 is slid upon the uppermost of the pipes whereupon a stop 95 is lowered to engage the last hank so that when the truck is withdrawn the hanks are left hanging from said uppermost pipe. After the hanks have been steamed they are pushed off the pipe into a container by advancing an ejector device 116. (For Figures see next page)
Patent GB-920203-A (GB)
Title: Method and apparatus for contacting gas with a liquid
IPC: B04C3/00
Filed: 1959-04-06
Abstract: 920,203. Contacting gases with liquids. RUHRCHEMIE A.G. April 6, 1959 [April 10, 1958], No. 11532/59. Class 55 (2). A method of contacting a gas with liquid comprises effecting the contact in a cylindrical tube, within which is mounted a member provided over substantially the whole of its length with means which impart a rotary motion to the gas stream, the gas being passed upwardly through the tube with a velocity sufficient for the downward fall or flow of the liquid under gravity in the zone of said rotary motion to be either retarded or prevented, with the result that the liquid is carried upwards. The method may be employed in the scrubbing out of impurities which are present in the form of dust or mists in gases or vapours, in the absorption of gases from gas mixtures or vapours and in effecting heat exchange between gaseous and liquid media. The member imparting a rotary motion to the gas stream may be of circular cross-section and may have vanes of metal plate or screw threads mounted on an internal cylinder. Alternatively, a plurality of ring- shaped metal plates disposed one above the other may be employed, the plates having guide vanes formed therein by suitable cutting and upward bending, or layers of segments of expanded metal may be employed. If desired, several units of apparatus, each comprising the cylindrical tube with the member for imparting a rotary motion to the gas mounted therein, may be connected in series. In Fig. 1, the interior of tube 1 contains a built-in cylindrical member 2, which is tapered at the top and bottom and is provided with guide vanes 3 whereby a rotary motion is imparted to the gas, which enters at 4, as it flows through the apparatus. Scrubbing liquid, drawn from collecting vessel 6 by pump 5, enters the apparatus through spray nozzle 7. Purified gas escapes at 8, while the liquid flows off in a downward direction to vessel 6. This vessel may be provided with an outlet 9, while scrubbing liquid may be introduced continuously or otherwise through feed line 10. In Fig. 2, vapours from chamber 17 pass up tube 12, in which is disposed device 11 provided with guide members 16. Condensate is precipitated from the vapour stream by cooling jacket 14 and collects in trough 13. This condensate serves as the scrubbing liquid and is entrained by the vapour stream as it passes constriction 15. The enriched scrubbing liquid is expelled by centrifugal force into a collecting trap 19 through annular slot 18 and is led off through line 20. In Fig. 3 (not shown), the cooling jacket 14 is located above the device 11.

Abstract: 1,002,714. Lubricating; bearings. ROLLSROYCE Ltd. March 19, 1964, No. 11762/64. Heading F2A. In a fan assembly for aircraft vertical-lift purposes a rotatable hollow shaft 19 carrying rotor blades 20 is mounted in bearings 14, 15 supported by a stationary casing 12 housing guide blades 13, and lubricating oil in a reservoir 31 flows under centrifugal action upwardly over the inner surface of a tapered hollow shaft 33 to pass through a plurality of apertures 35 in shaft 19 and downwardly through the bearings before returning to the reservoir through apertures 41 and a tube 42. Oil leaving apertures 35 is caught by a flange 45 and after passing through bearing 14 the oil flows over the exterior surface of shaft 19 to be caught by a similar flange 50 above bearing 15. A proportion of the oil collects in galleries or traps 46, 51 in shaft 19 to ensure adequate lubrication of the bearings when the fan is started, the oil passing into, or out of, the galleries through apertures 28, 35, respectively. Outward flow of oil through seals 24, 25 is prevented by pressurized air or gas fed to an annular chamber 37 through a pipe 40, the air or gas which passes between the seals being discharged through apertures 41, tube 42 and a pipe 43 at the uppermost end of shaft 19. Modifications of the fan assembly (Figs. 2, 3, not shown) mainly differ from the aforementioned assembly in that they comprise two sets of contra-rotating rotor blades or two sets of stationary guide blades, the bearings and lubrication passages being arranged accordingly. In each modification a syphon tube returns oil from the uppermost bearing to the reservoir, the lower bearing or bearings being fed with oil through apertures in a central tapered hollow shaft. Outward flow of oil through seals provided between the stationary and rotatable parts of the assembly is prevented by pressurized air or gas as in the aforementioned assembly.
