Title: Improvements in and relating to the production of regenerated cellulose shaped products, objects or articles
IPC: C08B1/08
Filed: 1958-03-17
Abstract: In the manufacture of regenerated cellulose shaped products from sheeted prehydrolysed sulphate chemical wood pulp by the viscose process, there is incorporated in the pulp (or in the alkali cellulose prepared from the pulp), at any stage prior to the completion of the shredding of the alkali cellulose, from 0.02 to 0.3%, preferably 0.1 to 0.2%, based on the bone-dry weight of the pulp, of a surface-active agent comprising the condensation product of refined tall oil containing about 25-35%, preferably 30%, of resin acids with (1) a mixture of propylene oxide and ethylene oxide or (2) propylene oxide and ethylene oxide introduced sequentially in that order, the molar ratio of total polyalkylene oxide to refined tall oil in the condensation product being from 2:1 to 100:1 and the weight ratio of propylene oxide to ethylene oxide in the condensation product being from 1:3 to 3:1, preferably 1:1.  On a molar basis the condensation products preferably contain about 5-10 mols. of propylene oxide and 7-14 mols. of ethylene oxide per mol. of refined tall oil. Examples are given of the preparation of viscose by the slurry and steeping processes and of filtration tests on the viscoses, 0.1% by weight (based on the bone-dry weight of the pulp) of surface-active agents according to the invention being added to the air-dry pulp sheet.  In an example of the preparation of a surfaceactive agent, a mixture of equal parts by weight of ethylene oxide and 1,2-propylene oxide is added to half its weight of refined tall oil containing 32% of resin acids and having a saponification number of 193, to which has been added a small proportion of sodium hydroxide.  The temperature and pressure are raised from 134 DEG  C. and 50 p.s.i. to 164 DEG  C. and 70 p.s.i. in 4 hours 40 minutes, during which time the mixed oxides are gradually added to the tall oil -sodium hydroxide mixture.  The product contains 7 ethylene oxide units and 5 propylene oxide units per mol. of tall oil.  Sequential type condensation products are similarly prepared, the propylene oxide being introduced into the reaction vessel before the ethylene oxide.

Filed: 1948-03-31
Abstract: 656,648. Cathode-ray oscillographs. AEROQUIP CORPORATION. March 31, 1948, No. 9121. Convention date, Nov. 22, 1947. [A Specification was laid open to inspection under Sect. 91 of the Acts on Oct. 23, 1948.] [Class 37] [Also in Group XXXVIII] In a fluid-pressure indicating system, comprising a cathode-ray oscillograph, a pressureresponsive resistance element 1 and a temperature-responsive resistance element 2 are connected with resistors 3, 4 and balancing potentiometer 6 in a Wheatstone-bridge circuit which is energized from a stabilized voltage source and has series potentiometers 7, 8 across its output whose sliders are connected to the inputs of a direct coupled push-pull amplifier A feeding the Y plates of the C.R.O. 20. The X plates are energized through a phase-splitting amplifier B from a thyratron time-base 21 having a switchable resistance capacity charging circuit 22-23 for adjusting the sweep frequency. The time-base circuit has 5 different modes of operation selectible by rotary switch 31a, 31b, 31c, and in the single-sweep position shown an impulse signal from the output of the amplifier A through condenser 32, and switch 31b triggers a second thyratron 33 to trigger the negatively-biassed grid of thyratron 21 so that the C.R.O. beam makes one sweep only. Thyratron 33 remains conducting until its anode circuit is broken at 35 to prepare for another sweep. In subsequent switch positions the thyratron 21 may be triggered direct from the amplifier output to give repetitive sweeps, or run continuously with internal or external synchronization or give single or repetitive sweeps triggered by short-circuiting the SYNC terminals 42, 43. A stable R.C. oscillator shown at 50 produces a timing wave which may be injected in the output of the second amplifier stage through switch 47, and the " X " deflection may alternatively be derived from a potentiometer linked mechanically to a device whose pressure conditions are to be measured. Potentiometer 12 controls the Y shift, potentiometers 7, 8 the Y axis sensitivity, variable resistance 14 the amplifier gain while the variable resistor 30 controls the beam speed and potentiometer 28 the starting position of the beam. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 664,354. This subject-matter does not appear in the Specification as accepted.
