Title: Use of polyethylene powder as coating for flat articles and especially for linings,as well as polythylene powder with a share of foreign polymer
IPC: D06M13/07
Filed: 1983-04-16
Granted: 1986-09-30
Abstract: Coating, esp. by printing with a powder or paste, is carried out with polyethylene powder (I) having a different polymer (II) adhering to the surface of the particles. Pref. (I) is LDPE powder. (II) is a polyamide, polyurethane, polyester, polyacrylate, polyvinyl halide, polyvinyl acetate, polyether and/or polyalcohol. A plasticiser (bisphenol A) may be added. The amt. of (II) is 0.5-25 (1-10) wt.% w.r.t. (I). (II) is applied as a soln. or dispersion and dried. A double dot coating may be used, the coated (I) providing a barrier layer preventing the top layer flowing into the interfacing. This barrier layer consists of (I) contg. 0.5-10% (II), whilst the top coat consists of a hot melt adhesive powder of copolyamide (m.pt. 80-130 deg.C) or copolyester (m.pt. 115-140 deg.C). (I) has a particle size distribution of 0-200 (9-80) microns. The breaking load of the (II)-coated (I) at room temp. is (min. 25, pref. min. 50%) lower than that of uncoated (I). The technique is esp. useful for coating woven, knitted and nonwoven textile, real and artificial leather and foams. The surface properties of (II)-coated (I) are about the same as those of (II) powder, allowing (I) to be applied in the same way as other more costly hot melt adhesive powders, e.g. (co)polyamides and (co)polyesters.

Patent GB-664414-A (GB)
Title: Process for purifying and concentrating crude unsaturated aliphatic aldehydes by extractive distillation
IPC: C07C45/78
Filed: 1949-01-07
Abstract: <PICT:0664414/III/1> Crude acrolein such as that obtained by catalytic oxidation of propylene, is separated from close-boiling saturated carbonyl compounds, e.g. propionaldehyde and acetone, by subjecting the mixture to extractive distillation in the presence of water so that water forms at least 80 per cent by weight of the mixture in the distillation zone; the distillation being carried out under sub-atmospheric pressure and at a temperature below 35 DEG C., preferably between 0 DEG  and 20 DEG C.  Purified acrolein containing less than 0.4 per cent of water, is withdrawn from the distillation zone as an overhead vapour product.  The process may also be used for the purification of methacrolein.  The crude unsaturated aldehyde is preferably submitted to preliminary treatments to eliminate normally gaseous and relatively high-boiling components.  A mineral acid, e.g. phosphoric acid, may be added to the water or to the crude aldehyde charged to the extractive distillation zone.  Crude acrolein from a reaction zone where the catalytic oxidation of propylene is effected, is quenched in line 10 with water introduced through line 12; and is then passed through cooler 11 into separator 13.  Acrolein is present in both the liquid and the gaseous phases in separator 13. The gaseous phase is scrubbed in column 15 with water introduced through line 16, the pressure being 125 p.s.i.g.  Propylene and other fixed gases are discharged through line 17.  An aqueous solution containing acrolein is withdrawn from column 15 through line 18, and combined with the liquid from separator 13; the mixture is then distilled in column 20.  The liquid bottoms which comprise an aqueous solution of formaldehyde and high-boiling components, are eliminated from the system.  The overhead vapours from column 20 which comprise acrolein (80 to 90 per cent by weight), acetaldehyde, propionaldehyde, acetone, and water, are submitted to extractive distillation in column 26.  Water is introduced through line 29 in order to maintain 83 per cent by weight of water in column 26.  The head and base temperatures are held at -9.7 DEG  and 15 DEG C. respectively, the corresponding pressures being 50 and 152 mm. absolute.  The reflux ratio is 2 : 1.  Purified acrolein (99 per cent) is taken off overhead, condensed in condenser 35 and withdrawn from the system through line 37.  A dilute aqueous solution of acetaldehyde, propionaldehyde and acetone is withdrawn from the base of column 26. In a modification, some of the acetaldehyde in the feed to column 26 is eliminated by subjecting part of the overhead from column 20 to preliminary fractionation in column 40.  The bottoms from column 40, which are substantially free from acetaldehyde, are then passed to column 26.

Filed: 1974-01-22
Abstract: 1514908 Armour - piercing projectile MALLORY METALLURGICAL PRODUCTS Ltd 22 Jan 1974 [8 Jan 1973] 924/73 Heading F3A An armour-piercing projectile comprises a body the nose of which is formed from a metal composition possessing high overall hardness, high tensile strength and high modulus of rigidity with the remainder formed from a metal composition possessing relatively lower overall hardness, higher ductility and lower tensile strength, the two compositions having been processed together by a common powder metallurgical method to form an integral structure. Such a projectile may be made by lining a metal can 10 with a rubber bag 11, the interior shape of the can 10 being similar to that of the projectile to be produced but of somewhat larger dimensions. A first powder mixture 'A' is introduced into the nose 12 of the can 10 and the can vibrated to settle the powder, a second powder mixture B then being introduced on top of the powder 'A' and the can again vibrated to settle the powder. The filled can is then closed by a closure cap 13 after sealing the bag 11. The can and its contents are subsequently subjected to an isostatic pressure of 2000 atmospheres in a pressure vessel, after which the pressed compact is removed and subjected to a sintering operation in an atmosphere of H 2  or cracked NH 3  on a bed of refractory oxide at 1500‹ C. for a period sufficient to effect liquid phase sintering of both powder compositions. The metal alloy components are integrally connected without a sharp line of demarcation between the compositions "A" and "B". In order to produce a hollow projectile body two concentric tubes may be introduced into the rubber bag and subsequently the respective powder mixtures introduced one between the outer tube and the bag and the other between the two tubes, leaving the inner tube empty, the outer tube being withdrawn after or during the charging operation. The powder mixture "A" may comprise WC, Co or W, Ni, Fe, Mo, while powder mixture "B" may comprise W, Ni, Fe or W, Ni, Cu, the tungsten content being at least 80 wt.per cent.

Title: Carriage latch for a disc drive
Inventor: WIENS JOHN POLING
IPC: G11B5/54
Filed: 1990-11-01
Abstract: The disclosure relates to a dynamic lock for a disc drive carriage incorporates a plunger (34) that captures an extension on the carriage (12). The plunger is guided by a solenoid (36) and frame (30). The plunger is spring loaded (38) such that it normally is biased into the carriage to restrain the carriage in the home locking position. The solenoid (36) can withdraw the plunger and allow release of the carriage. A counterweight (40) rotates about a pivot (50) provided on the frame adjacent the plunger. A finger (42) that protrudes from the counterweight rides in a recess on the plunger. In the event of a sudden shock to the disc drive, the shock force is transmitted from the plunger (34) through the finger (42) to the counterweight (40). The counterweight is designed to be of equal mass to the plunger (34), whereby the shock force is neutralized, preventing the plunger from moving back toward the solenoid and releasing the carriage (12).

Title: Detecting device for internal abnormality of transformer
Inventor: INAGAKI KEISHIN
IPC: G01R31/06
Filed: 1981-01-07
Abstract: PURPOSE:To obtain a trouble detecting device of low cost and yet high reliability by making such an arrangement that when transformers end each of which is divided into more than two sections are used by combinding them with one another, physical values at the same points on all the transformers are compared with one another, and if the comparison value proved to be different from the value of normal time, an abnormality is judged to have coccurred. CONSTITUTION:Tanks 11 and 12, steel cores 21 and 22, and windings 31 and 32 of first and second unit transformers are manufactured to the same specification, and detecting means 41 and 42 are installed on almost same locations in respective tanks 11 and 12, and therefore, voltages detected by the respective detecting means are to take almost same values when operating in the normal condition. If an abnormality, such as shortcircuit of winding, etc. occurred in the tank 11 or the tank 12, leaking magnetic flux in the abnormal-occurring tank varies, and therefore, it is obvious that a difference is caused to detecting voltage between the detecting means 41 and 42, and then, it becomes possible to easily detect occurrence of an abnormality in the tank by comparing the two voltages with each other by a comparing means 5. As this device requires no current transformer, it can be operated economically, and since it maintains the same phase even at the time of impression of voltage, it is not necessary to consider possible influence by exciting rush current.
