Title: Method of Manufacturing Porous Products from Films or Filaments.
Inventor: RASMUSSEN OLE-BENDT
IPC: D01D5/42
Filed: 1966-08-24
Abstract: 1,199,566. Making porous products from films and filaments. O.-B. RASMUSSEN. 18 Aug., 1967 [24 Aug., 1966], No. 38072/66. Addition to 1,148,382. Heading B5B. [Also in Division C3] Porous products are made by melt mixing a film- and filament-forming polymeric material A colloidally with a polymeric material B that has a lower molecular weight, a lower melting-point and a higher melt index than A, is incompatible with A and is chemically different from A, extruding the molten mixture as a sheet or filament and phase orientating the extruded product by stretching in the direction of extrusion, cooling the stretched sheet or filament to make the polymeric material A crystallize and agglomerate while the material B is still in the liquid state, fibrillating or partly removing the material B and thereafter reinforcing the structure of the product by a cross-linking or a polymerization reaction of the material B. The removal of part of the material B may be effected by dissolution with a solvent which dissolves the B phase but not the A phase. Polymerization may be effected by polymerization in situ of a monomer which is soluble in the B phase. Cross-linking may be effected by a gas phase reaction. The material B may be a graft polymer in which ethylene oxide has been used for the grafting, e.g. the graft polymer may be produced by grafting polyoxyethylene chains on to either material A or a polymer which is soluble in A. The A phase may be a polyamide and the B phase may be a graft copolymer of the same polyamide and polyoxyethylene. In an example, to isotactic polypropylene with melt index 0À3 is admixed 30% by weight of a copolymer of 29% of vinyl acetate and 71% of ethylene, the copolymer having a melt index of 15 (A.S.T.M. method, Condition E). The components are emulsified into one another and the mixture melt-extruded as a film. In a second example, to polycaprolactam of melt index 0À35 (condition K) is admixed 35% by weight of polyoxyethylene of melt index 3 (Condition E). In a third example there is admixed to the polycaprolactam of Example 2, 35% by weight of a graft copolymer of 30% polyoxyethylene and 70% of polycaprolactam.

Title: Frequency divider circuits
IPC: H03B19/12
Filed: 1960-11-11
Abstract: 964,424. Frequency divider circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 11, 1960 [Nov. 13, 1959], No. 38848/60. Headings H3P and H3T. In a frequency divider of the type in which a normally charged energy storage device is periodically discharged under the control of the input signal, the amount of stored energy prior to the discharge is reduced by a conical voltage as the input frequency is increased so that, for example, the division ratio is maintained constant. Fig. 4 shows a circuit in which, in the rest condition, a condenser has been charged through a resistor 18 to a value insufficient to break down a negative resistance device 20 such as a gas-discharge tube or a PNPN or Reeves diode. An input signal at 26 from the signal to be divided in frequency causes the diode to breakdown and so discharge capacitor 10 to a value at which the negative device becomes high resistance again. Thereafter the capacitor 10 charges through resistors 16 and 18 until after a predetermined number of input cycles the voltage across the capacitor is such that the next negative halfcycle will retrigger the negative resistance device 20. Accordingly, an output may be obtained from a cathode follower valve 14 of saw-tooth wave form having a frequency which is a subharmonic of the input frequency. Part of the output voltage from the cathode follower is fed through a potential divider 13 and 24 and an averaging circuit 22, 28 to bias the diode whereby the operative portion of the charging curve of the capacitor moves from the region 40-42 (Fig. 3), to the region 44-46 so that the charging rate of the capacitor is automatically increased with increase in input frequency so as to maintain the division ratio constant. The change in bias voltage is due to a change in average current through the cathode follower valve resulting from the sawtooth waves having a higher convex curvature value when they are derived from the upper part of the charging curve, e.g. 40 to 42 than a lower part, e.g. 44 to 46. The first stage of frequency division is followed by two succeeding stages differing from the first in that the compensating voltage is derived from the preceding circuit through resistors 48a and 48b instead of by regenerative action from its own output circuit. The input signal can alternatively be applied to the right-hand electrode of the diode 20 (Fig. 5, not shown). In Fig. 6 (not shown), the capacitor 10 is replaced by a capacitor of the potential variable diode type and compensation is obtained by connecting the output of the averaging circuit to the lower plate of the capacitor to control its capacitance. It is stated that in Fig. 1 an inductance could be substituted for resistor 18 and a resistor for capacitor 10.

Abstract: 1,099,949. Magnetic structures. REEVES INDUSTRIES Inc. Sept. 10, 1965 [Sept. 10, 1964], No. 38850/65. Heading H1H. A magnetic record member is lubricated by forcing lubricant under pressure into the pores of the finished record member. In the Figure, a tape 10 passes between rollers 14, 16 one of which deforms elastically while the other is comparatively rigid. A continuous stream of lubricant 28 is applied at the nip of the rollers and dirt &c. is carried away to the sides. The rollers are wider than the tape. The tape materials are conventional and the lubricant is an aliphatic mono-ester (preferably butoxy ethyl stearate) or a sperm oil or an ester of an aliphatic substance with polysubstituted siloxanes or a fluorinated hydrocarbon. The lubricant may alternatively be an emulsion or dispersion of a solid such as trichlorotrifluoro-ethylene in alcohol or water. A swelling agent may be added to facilitate penetration. One of the rollers is heated and rotates faster than the other so as to polish the tape.
