Title: Apparatus for melt-spinning synthetic linear polymers
Inventor: DAVIES GERALD THOMAS
IPC: D01D4/00
Filed: 1954-11-11
Abstract: <PICT:0779787/IV(a)/1> In melt-spinning apparatus of the type described in Specification 533,307, [Group IV] comprising a melt grid on to which solid polymer in particulate form is caused to fall and through the interior of which a heating fluid is circulated at a controlled predetermined temperature, a heated chamber below the grid containing a filter pack and spinneret through which the melt is forced, the chamber has a socket into which is detachably received an assembly comprising a filter pack and spinneret, the construction and arrangement being such that the socket and the assembly are in heat-conducting relationship at a number of points.  As shown, molten polymer is supplied to a jacketed socket 11 through a duct 1 by a pump (not shown) from a reservoir of polymer in a melt chamber, and the melt is forced through a sand pack 3, a screen assembly 5 and a metal spinneret plate 7.  The sand in the pack 3 is laterally retained by a metal holder 9, which is forced into tight engagement with the inner wall of the socket 11 by means of screws 13 in a metal retaining ring 14 for the spinneret, this ring being screwed into the bottom of the socket 11, so that there is direct contact between the spinneret and pack assembly and the inner wall of the socket 11 at the top of the pack holder 9, where there is situated an aluminium gasket 15, and at the points of contact of the screws 13 with a metal gasket 16 under the spinneret 7.  In order to provide an additional contact, the outer wall 17 of the pack holder 9 is stepped about mid-way along its length and an additional aluminium gasket 19 is provided at the area of contact of this step with a complementary step in the inner wall of the socket 11.  Spaced circumferential grooves 21 are machined in the metal wall of the socket 11, and a cylindrical outer wall 23 is welded across the top and bottom flanges of the socket so as to surround the grooves 21 and provide a jacket surrounding the socket, the grooves 21 with their intermediate ridges 24 thus providing a considerable area of surface to heating fluid circulated through the jacket from an inlet pipe 25 and discharged from the jacket through an outlet pipe (not shown).  By controlling the temperature of the heating fluid the temperature of the melt at the instant of extrusion may be controlled within \sB 1 DEG  C.  As a further aid to close control of the temperature of the melt at the spinneret plate 7, a small reservoir of melt may be maintained immediately above the spinneret plate by means of a screen-supporting and melt-distributing metal plate positioned between the screen assembly 5 and the spinneret plate.  Such a melt-distributing plate may comprise a disc with uniformly spaced and relatively large orifices therethrough, having an annular gasket between its lower surface and the upper surface of the spinneret plate to define a small space between them.  Specification 536,379, [Group IV], also is referred to.

Abstract: 760,949. Dispensing towels. NIET, J. M. D. DE. Nov. 22, 1954 [Nov. 25, 1953], No. 32753/53. Class 18. [Also in Group XVIII] An apparatus for dispensing towels contains groups of towels, each group consisting of a number of towels clamped together at an edge, the towels being withdrawable one at a time with part retained in the apparatus, and pulled back into the apparatus after use. The towels are clamped between bars 32, 34 held at their ends by caps 36 slidable in guideways 38. The groups of towels are pressed against the top of the apparatus by sliders 22 pulled upwardly by springs 25. In one embodiment the top towel is withdrawn through a slot 8 and after use a pedal 18 is depressed causing fingers 50 on the ends of arms 42 to swing downwardly, engaging the used towel and pulling it into the apparatus. To prevent another towel being withdrawn before the arms 42 return to their raised position depression of the pedal 18 causes a shutter 64 to move over an access notch 10. In another embodiment, Figs. 6-8 (not shown), a shutter prevents access to the towels until the pedal is depressed, raising the shutter and the towel withdrawing fingers. A dashpot controls slow automatic withdrawal of the towel by the fingers as they descend.. When a group of towels is soiled, the pulling out of the first towel of the next group causes the caps 36 of the. soiled group to rise clear of the guideways 38 and the soiled towels and their clamping means to fall to the bottom of the apparatus.

Title: Improvements in or relating to the preparation of metal soaps
IPC: C07C51/41
Filed: 1962-08-27
Abstract: Metal soaps, defined as the water insoluble salts of organic acids having at least 6 C atoms and a metal other than an alkali metal, e.g. aluminium, the alkaline earth metals, lead, zinc, are prepared by forming an aqueous suspension of an oxide or hydroxide of a metal capable of forming a basic metal carbonate, reacting such suspension with carbon dioxide, while stirring to form a suspension of the basic carbonate, forming an aqueous emulsion of a molten or liquid fatty acid in the presence of ammonia and adding the emulsion to the suspension to form the metal soaps.  The reaction with carbon dioxide may be effected by passing the gas through the suspension for 1 to 4 hours.  The invention is particularly described with reference to the preparation of zinc stearate and lead stearate, which are recovered by filtration.
Patent GB-279772-A (GB)
IPC: F16H29/08
Filed: 1926-12-29
Abstract: 279,772. Lange, A. Nov. 1, 1926, [Convention date]. Variable-speed gearing comprises a rotary driving cam 2, Fig. 2, designed so as to impart uniform motion to a one-way driven wheel 16. Power passes by way of a lever 3, a link 7, a variable lever 8, and a link 14 to the one-way drive. The speed is varied by displacing a fulcrum block 9 through which the lever 8 passes. The block 9 slides in guides 20. The one-way drive may be a pawl and ratchet. In the arrangement shown, the link 14 is pivoted to a ring 27 which oscillates about the driven wheel 16 and carries a number of spring plungers 28 adapted to engage holes in the wheel 16. The plungers 28 are raised out of engagement at the end of their stroke when a tappet 34 strikes an abutment 36. A lever 32 then actuates a pin 33 on an outer cam ring 31, so as to advance that ring. A tail 29 of plunger 28 rides up a cam 30 into a retaining notch 37. At the end of the return stroke, the tappet 34 strikes an abutment 35 so as to release the plunger 28 for the drive stroke. When change-speed lever 24 is operated, the abutments 35, 36 are displaced in unison with the block 9 through rack-and-pinion and screw gearing. The whole gearing may be arranged in multiple phase. To eliminate back-lash in the cam drive, the cam groove 2 may be duplicated as shown in Fig. 3, the lever 3 carrying duplicated spring-pressed conical bowls 41.

Title: Improved hood latching means for vehicles
IPC: E05B65/19
Filed: 1946-11-06
Abstract: 628,135. Hook fastenings. BURGESS, A. F. (Krause, W. H.). Nov. 6, 1946, No. 32968. [Class 44] [Also in Group XXXI] A latch assembly for motor-car bonnets of the type which are hinged and latched on both sides is shown fastened in Fig. 5 and unfastened in Fig. 6. It comprises an apertured keeper plate 11 on the bonnet, a latch base 8 on the fixed part and a latch 31 pivoted at 30 to the base and having a hook part 32 to engage the part 15 of the keeper plate. A two-armed link pivoted at 35 to the latch carries on one arm 36 a roller 39 engaging a curved slot 44 in a raised guide 43 and of such a shape that any tendency of the latch to turn from the locking position is prevented by the engagement between the roller 39 and the side of the slot 44. The other arm 37 is attached to an operating rod 51 which when pulled first tilts the link from the locking position and then turns the latch towards the released position. An over-centre spring 62 mounted on a fixed stud 65 acts on the pivot 35 to urge the latch 31 to either of its terminal positions. A spring 58 is provided between the latch and link which assists the spring 62 in urging the link to the locking position. As the keeper plate 11 is moved to the closed position, it contacts an arm 33 on the latch member 31 turning it towards the latching position. This movement is completed by the over-centre spring 62. In the unlatching movement, the arm 33 contacts the underside of the plate 11 to cause a small displacement towards the open position. The latch base 8 is carried on a pivot so that when the motor-car bonnet is fastened on one side it may hinge about that side whilst being opened from the other side. One or more centering members 9 may be provided on the base 8 for co-operation with holes 10 in the latch plate 11. In a modification the curved slot 44 is replaced by a member having a raised curved edge forming a guide for the roller.

Abstract: 1533007 Heat setting of extrudate A HEGGENSTALLER 9 Aug 1976 [12 Aug 1975] 33127/76 Headings B4-B5 A mixture of waste of wood particles or textile fibre with a binder, which is extruded by a piston extruder, is heat set downstream of the extruder die under pressure, during sliding passage through a channel defined between at least one pair of opposed elements 2, 3, of which one 2 is fixed against displacement transversely of the extrudate, and the other, 3 is transversely displaceably urged against the extrudate, by a loading means 24, 25, which may comprise compression springs, or an hydraulically or pneumatically operated piston, to a location which is peripherally spaced from the element 2, to permit escape of moisture from the extrudate, and permit the loading to be maintained constant, or varied. Preferably, the extruder piston and the means 24, 25 are hydraulically actuated from a common pressure source, with an overload protection afforded by a control which, when an adjustable extrusion pressure is attained, reduces the operating pressure of the means 24, 25 to a level which is also adjustable. The element 3 may exert a lower pressure during an extrusion then during a retraction stroke of the extrusion piston when stress relaxation of the extrudate is accordingly prevented. The elements 2, 3, may comprise a single pair engaging a cylindrical extrudate, Fig. 2 (not shown), or two pairs of plates 5 as in Fig. 1, which, with the means 24, 25, are preferably supported on a plurality of pairs of frames 11 spaced apart in the direction of extrusion with each frame of a pair comprising a member 12 carrying the stationary elements 2, and a member 13 releasably clamped thereto at 15, 16 and pivotable apart therefrom at 14, e.g. for releasing defective extrudate. One frame 11 of each pair is fixed, and the other 11 is slidable under thermal expansion at 18 in a guide 17, and each frame 11 is also vertically and horizontally adjustable for alignment with the extrusion die. Each element 3 is mounted for its transverse displacement to the frame member 13 by bolts 19 which support a plate 10 of the element 3 at heads 22 and are loaded on the other side of the member 13 by adjustable springs 20. To prevent the transversely displaceable element 3 being displaced with the extrudate by frictional contact, each element is also supported to the frame by a transversely spaced pair of tie rods 29, Fig. 4, engaging both the frame member 13 and lugs 27 of the element 3, at pivots 30 which permit the transverse displacement of the element 3.
