Title: Improvements in or relating to preparing yarns in and for the production of stretchable knitted fabric
IPC: D02G1/02
Filed: 1955-02-08
Abstract: 803,471. Knitting; finishing fabrics. PATENTEX, Inc. Feb. 8, 1955 [Sept. 3, 1954], No. 3703/55. Classes 42 (1) and 74 (2). [Also in Group IX] Elastic stretchable (120-250 per cent) fabrics or stockings are knitted from monofilament yarn of thermoplastic polymer, e.g. nylon, prepared by first twisting, e.g. 5-40 turns per inch, in one direction and then winding on to a bobbin in a direction to impart to the yarn a twist opposite to the twist of the first twisting step ; the yarn may have been pre-set by heat treatment, with or without shrinkage. After knitting, the fabric is relaxed to allow creping, i.e. the knit loops turn on to their edges under the action of the released torque in the yarns, which produces a herring-bone pattern and/or washboard effect and the fabric is heated to set it in its relaxed condition. The fabric may be relaxed by standing free from tension at room temperature for 2-24 hours and then set e.g. placed in loose form in a treating chamber and exposed to heat (water vapour) at a temperature of 170- 210‹ F. and relative humidity 70-100 per cent for 15-60 minutes, then scoured, dyed and boarded on forms of reduced size compared with the stretched dimensions. In knitting the leg and/or welt, at least, of a stocking, yarns which have been first twisted in opposite directions (one or both of which may have been pre-set) may be knitted into alternate courses or sets thereof (up to four such courses) and/or one or both may alternate with other similarly or oppositely twisted or untwisted monofilament or multifilament yarns at least some of which may differ in denier. Specification 786,551 is referred to.

Patent GB-657448-A (GB)
Title: Improvements relating to frequency modulation radio altimeters
IPC: G01S1/02
Filed: 1949-02-14
Abstract: 657,448. Frequency measurements. SOC. FRANCAISE RADIO-ELECTRIQUE. Feb. 14, 1949, No. 4021. Convention date, Feb. 18, 1948. [Class 37] [Also in Group XL (c)] In a radio altimeter in which the frequency of the transmitted wave is periodically varied and the difference between the frequencies of the transmitted and received waves is measured, a limiting amplifier is employed having two valves in which the anode current remains constant over a large range of anode voltage when the voltage of one of the grids between the control grid and anode of each valve remains constant. The control grid of the first limiter valve 1 is supplied with the signal voltage through a condenser 2. A part of the rectangular waveform voltage developed across the anode load resistance 16 is applied to the control grid of the second limiter valve 8 through a voltage divider comprising two resistances 9, 10. The valve 8 has a load resistance 11 and the screen grids of the valves 1, 8 are connected in parallel and supplied with current through a common resistance 12. Grid bias for the valve 8 is obtained from the voltage drop of the cathode current of the two valves across resistances 13, 14 from which the grid bias voltage for the valve 1 is derived through a resistance 15. The resistances 9, 10 have such values that variations of grid voltage of the valve 8 are equal to those of the valve 1 but of opposite sign, so that the sum of the screen mean currents is constant and the voltage drop over the resistance 12 is constant. The amplitude of the output voltage is thus independent of the shape of the signal voltage wave as long as the amplitude of the signal is sufficient to saturate the valves 1, 8. The anode of the valve 8 is. connected to earth through a condenser 3 and oppositely connected rectifiers 4, 5, in the circuit of one of which is an ammeter 6, the reading of which is proportional to the number of charges received by the condenser 3 in one second and therefore to the frequency of the signal voltage. The meter may be graduated in metres to constitute an altimeter. Alternatively, the valves 1, 8 may be connected in a flip-flop circuit. The condenser 3, rectifiers 4, 5 and meter 6 may alternatively be connected in the anode circuit of the valve 1 or between the anodes of the valves 1, 8. The valve which is not connected to the condenser 3 may be connected to a similar circuit 3, 4, 5 including a relay which actuates pilot lamps corresponding to preselected heights.

Title: Improvements relating to cellular materials
Inventor: WILSON PAUL IVAN
IPC: C08J9/35
Filed: 1962-02-05
Abstract: Fragmentary polymeric foam material is bonded by allowing a polymer containing terminal hydroxyl group to react with a polyisocyanate without extranous heat to give a prepolymer which is mixed with the fragments and cured.  Specified hydroxy polymer are: polyether diols derived from ethylene and propylene oxides and polyether triols derived from triols, e.g. trimethylol propane, hexane triol or glycerol and polypropylene oxide, this product being subsequently optionally reacted with ethylene oxide. In prepolymer formation there may be 4-5 -NCO groups present per OH group.  A catalyst, e.g. diazobicyclooctane in aqueous solution, may be used.  The same or a different catalyst may be used in the curing step if heat is not applied.  Curing may be by cross-linking with water.  The products may be resilient.  In Example (1) a prepolymer prepared from tolylene-2,4 and 2,6-diisocyanate and glycerol-centred-poly-propylene oxide triol is mixed continuously with resilient polyether polyurethane fragments, and diazabicyclooctane in water and cured under pressure in moulds with application of heat.  In Example (2) diazobicyclooctane also catalyses the pre-polymer formation.  In Example (3) rubber latex fragments are used.
