Abstract: 999,072. Melt-spinning synthetic filaments. BRITISH NYLON SPINNERS Ltd. Jan. 9, 1964 [Jan. 25, 1963], No. 3197/63. Addition to 901,398. Heading B5B. The melt spinning process of the parent Specification (wherein there is continuously and uniformly provided immediately below the spinneret plate a homogeneous and laterally unconfined shallow layer of an inert gas, such as superheated steam, in contact with the entire surface area of at least that portion of the face of said spinneret plate which contains the extrusion orifices) is modified in that the layer of gas is provided by two streams of gas emanating from opposing sides of the face of the spinneret plate, the width and direction of each such stream being such that that part of the spinneret plate containing the orifices is blanketed with the gas. As shown in Figs. 1 and 2, a pack and spinneret assembly comprise two inwardly-facing elongated slots 1, 2 to each of which superheated steam is provided under pressure, the slots being located in flanges parallel to and contiguous with the long straight sides of the spinneret 3 of a " datebox " pack 4. The slots extend outwardly in their length direction to points beyond the short convex ends 5, 6 of the spinneret, in order that the outer orifices at those ends shall be completely blanketed with steam. The " datebox " pack comprises a pack holder 10 and a lid 11, filtering material 13 held between top screen 14 and spinneret screen 15, and a spinneret 3 mounted on a shoulder at the bottom of the holder. The steam from a supply pipe 16 is supplied to the slots 1, 2 by drillings 8, 9 formed in the lid 11 and the pack holder 10. Baffle means 17, 18 are positioned at the location where the drillings open into the slots, in order that the steam shall flow along the length of the slots in both directions, before flowing out of the slots across the face of the spinneret. Screw-threaded rods 19, 20, as steam diffusing means, are fitted in the lips of the slots 1, 2 and cause the steam to be evenly distributed along the full length of each slot. The helix angle of the screw of the rods is preferably a low one. If diffusing means are omitted from the slots 1, 2 the steam provided in the vicinity of the spinneret plate must have expanded to atmospheric pressure or must have been pre-diffused prior to its arrival in the slots, to fill them uniformly.

Abstract: 829,341. Stuffing-box substitutes. BENDIX AVIATION CORPORATION. Jan. 30, 1957 [Feb. 6, 1956], No.3317/57. Class 122 (5). A fluid-pressure seal between a surface 20 and a member 14 which is axially reciprocatable through an opening 16 in the surface and also capable of radial movement with respect to the opening, comprises an O-ring 34 of rubber-like material which tightly engages the surface of the member 14, a disc 36 positioned between the ring 34 and the surface 20, which it sealingly engages, and a retaining-member 40 which is spring-loaded to engage the ring 34. The internal diameter of the O-ring 34 before assembly is less than the outside diameter of the member 14. The disc or sealing washer 36 is made of stiff non-metallic material, e.g. nylon, or fabric impregnated with phenolic resin, and it bears against a facing 38 of smooth semi-resilient material, e.g. rubber, on the surface 20. The retaining member 40, which is cup-shaped, is biased against the ring 34 by a coil-spring 42 located between the retainer 40 and a spacer member 22. The rim of the retainer 40 is recessed to provide an abutment surface 46 which engages the periphery of the disc 36 at a distance spaced axially from the inner portion of the retainer and less than the " free " thickness of the ring 34 to provide a predetermined deformation of the ring. The sealing washer 36 may be, alternatively, of metal and lapped to provide a direct metallic sealing contact with the surface 20. The radial clearance of the opening 16 in the surface 20 allows the member 14, which may be the actuating member of a pneumatic servomotor, as described in Specification 829,030, a slight angular movement during reciprocation, as when its remote end is attached to a linkage requiring an arcuate motion.

Title: Method of and apparatus for baling
IPC: B30B9/30
Filed: 1966-01-26
Abstract: 1,095,626. Baling presses. AMERICAN BALER CO. Jan. 26, 1966 [Feb. 23, 1965], No. 3491/66. Heading B5F. Apparatus for compacting and forming wood pulp etc. into bales comprises the combination of (i) compactor and extruder means 10, (ii) separating and conveying means 11 and (iii) intense pressure bale-forming means 12. The wood pulp is fed in loose condition through a hopper 18 into a baling chamber 14 where it is compacted by a baling head (16) reciprocated by an hydraulic cylinder (17) (Fig. 4, not shown). The bailing chamber 14 leads to a throttling device 15 having at least a pair of opposite side walls 20 which can be moved together to form a variably tapered constriction by means of an hydraulic cylinder 22 and linkage 23, 24. The wood pulp is compacted in layers to form a selfsupporting cubic extrusion W (Fig. 9) which is fed on to a table 29 in the separating and conveying section 11. A transfer car 32 having wheels 34 running on rails 30 is provided with a pair of gripping arms 36 attached to the car by means of swinging links 42. The upper ends of the arms 36 are interconnected by a lost motion telescopic connection 45, and the arms are actuated by a double-acting hydraulic actuator 51. When the actuator 51 is extended, gripping flanges 40 carried by arms 36 are pressed into the sides of the extrusion W to grip it firmly. Then, on account of the links 42, the arms 36 lift a length of the extrusion and separate it for transfer by the car 32 to the intense pressure section 12. During the lifting motion of the arms 36 the car 32 is being moved by a double acting hydraulic actuator (58) (Fig. 7, not shown) carried by the car 32 and connected through a jointed transfer arm 54 to a fixed point (56) on the machine. The intensifier section includes a pressure chamber 70 comprising a fixed part 71 and a movable part 77 (Fig. 11). The fixed part 71 consists of an end wall (72) (Fig. 13, not shown) and top and side walls 73, 74. The movable part 77 comprises bottom and side walls 78, 79 mounted on wheels 81 for movement along rails 80 by means of crank arms 83 driven by a rotating hydraulic motor (86) (Fig. 13, not shown). End portions 82 of rails 80 are curved upwardly so that as the movable part 77 travels towards the fixed part it is given a slight lift into its final closed position. A number of movable hook links 90 engaging with corresponding lugs 91 hold the parts 71, 77 in the closed position, the hook links being operated by a shaft 102 through a bell crank 101 and tie rods 99. An end wall (76) of the pressure chamber 70 is then moved by an hydraulic actuator 75 towards the closed end wall (72) to compress the bale under intense pressure. The apparatus is controlled by two hydraulic systems, one (Fig. 14, not shown) for the compactor section 10 and the other (Fig. 15, not shown) for the separating and conveying section 11 and the intensifier section 12.

Title: Method for oxidizing carbon monoxide contained in moist air
IPC: C01B32/50
Filed: 1972-01-26
Abstract: 1371402 Oxidation of carbon monoxide KACHITA CO Ltd 26 Jan 1972 3615/72 Heading C1A [Also in Division F4] Carbon monoxide contained in moist air is oxidized by first passing through a dessicant to dry the air, secondly through a catalyst of natural zeolite nickel with an equal @@@@@@ a mixture of MnO2 and CuO in an amount of 70 : 30 by wt. to oxidize the CO to CO2 and finally through a second dessicant. The dessicant, which may be silica gel, active alumina or natural zeolite is regenerated by passing dry air through it, so operation is such that when the first dessicant becomes saturated the flow is reversed through the three systems, thereby causing dry air to flow through the saturated dessicant and thus regenerate it. The dessicant may be replaced by the catalyst mixture, in which the natural zeolite behaves as the dessicant.

Filed: 1949-02-10
Abstract: <PICT:0676744/III/1> <PICT:0676744/III/2> Plastic articles, e.g. ice cream blocks, are conveyed to a seizing station where spiked members 46 seize the articles and carry them through a coating bath and then deposit them for further treatment, unless a detecting device 29, adjacent the seizing station, detects that an article is absent or of insufficient thickness when actuation of the corresponding spiked members is prevented.  Ice cream blocks 13 are cut from a strip 11 by a cutting device 14 (see Group V) and deposited on a conveying member 21 which carries them past a detecting member 29 (see Group XIX).  If a block 13 is of sufficient thickness, member 29 is operated against the action of weighted arm 31 to cause link 32 to operate lever 34 and release member 38 thus allowing member 38, 39 to be operated through link 62 and lever 63 by cam 67 to push abutment 42 forward and cause spiked members 46 to seize the block.  The spiked members are operated by links 61, 59, 57 and through racks 60 as described in Specification 648,735, [Group VI].  The members 46 are carried on a rotating arm 44 raised and lowered by cam 48 so that the blocks are dipped in bath 71 and then carried to the wrapping mechanism (see Group XVII) where they are wrapped, the wrapping mechanism operating only if a block is impaled on the spiked members.  The second Provisional Specification also describes the use of stationary spike members with a movable coating bath.  Both Provisional Specifications mention the use of a delayed action device between the detecting device and actuation of the spike members.
