Patent GB-487652-A (GB)
Title: Improvements in the manufacture and application of polymerised alkylene oxides
IPC: D06M15/53
Filed: 1937-10-29
Abstract: Alkylene oxides are polymerized by causing them to stand in liquid condition in contact with an alumina earth, e.g. fuller's earth which has been activated by heating to 370-480 DEG  C.  The time of contact may be 2-7 days.  The mixture of polymers may be separated from the alumina earth by extraction and/or distillation and separated into fractions by distillation, fractional extraction or fractional precipitation.  Less viscous fractions are particularly useful as textile lubricants if desired in admixture with oils, fats or sulphonated products thereof.  More viscous fractions are suitable as sizes, either alone or with starch, gelatine or oils.  All fractions are suitable as plasticizers and swelling agents for organic derivatives of cellulose with which they yield strong, clear, crease-resisting films.  In an example, 50 parts of fuller's earth activated by heating to 370-480 DEG  C. are added to 100 parts of liquid ethylene oxide, and the mixture is kept at 0 DEG  C. for 2-7 days.  Residual ethylene oxide and aldehydes formed are removed by evaporation and the polymers dissolved out with water or benzene. Addition of ether to a benzene solution of the polymers precipitates a soft white rubbery solid fraction, and further addition of ether a waxy solid fraction.  Still more ether yield a syrupy liquid fraction, and a residual liquid fraction.ALSO:Sizes for textiles, e.g. yarns in slasher operations, or as tacking medium for doubling yarns with little or no twist, comprise polymers of alkylene oxides alone or mixed with starch, gelatine or oils.

Abstract: 771,953. Making flanged pipes. KRAUS, J. J. Oct. 18, 1955, No. 29732/55. Classes 83 (2) and 83 (4). [Also in Group XXVIII] In a method of making flanges for a thinwalled tube 24, Fig. 4, a strip 32 is coiled edgewise into a helix conformable to the surface of the tube and a ring cut therefrom is welded or brazed into position. Separate rings may be initially cut from the helix or the end 28 may be progressively tack-welded to the tube until the length of the strip can be exactly determined in order to prevent any overlap or gap. The end face 26 is finally smoothed by light grinding. In coiling the strip the material may be given a torsional stress so that the rings will lie flat after severance.

[Also in Group XIII] The pressure of air or gas being heated in a ceramic-walled recuperator 2 is reduced to the pressure of the flue gases in the recuperator by introducing into the air or gas leaving the recuperator a stream of gas under pressure directed towards the combustion chamber 1 of a furnace. In the form shown in Fig. 1, a blower 9 delivers flue gas from a flue 3 to an injector 7 in a venturi passage supplying fuel gas from the recuperator 2 to the chamber 1. The supply of flue gases to the nozzle 7 is con. trolled by a damper 11 regulated by the pressures of the fuel gas in the pipe 4 leading to the recuperator and of the flue gases in the pipe 11. A damper in the flue 3 is controlled by the pressure in the chamber 1. A valve 17 controlled by a temperature-responsive element 18 in the combustion chamber controls the fuel gas supply, and the air supply is correspondingly regulated by a valve 21 controlled in response to pressures in the gas, and air supply pipes 4, 12. In a modification, Fig. 3, the nozzle 34 induces a flow of fuel gas from a recuperator into a tube 40 composed of inter-fitting refractory rings, and the mixture delivered into the outlet 42 to the combustion chamber induces a flow of air from another recuperator. A pearshaped obturator 35 in the nozzle 34 is carried by rod 36 movable by hand or by a piston in a cylinder under the control of the pressure of the flue gas delivered by the blower and of the fuel gas supplied to the recuperator.

Title: Method of producing boron-hydride-nitrogen compounds
Inventor: JENKNER HERBERT
IPC: C07F7/18
Filed: 1961-08-21
Abstract: Amine-borines and aminoborines are made by reacting a boric acid ester with a silicon hydride compound (i.e. a compound containing at least one Si-H linkage) and an organic amine. Amine-borines are produced from tertiary amines such as trialkyl amines, or pyridine. When secondary amines are used, then aminoborines are obtained in addition to amine-borines.  Silicon hydride compounds include monosilane and organosilicon hydrides such as those of the formula SiRxH4-x, where R may be a hydrocarbon, or alkoxy radical or a halogen atom and x is 0, 1, 2 or 3.  The boric acid ester may be an orthoboric acid ester containing up to 4 carbon atoms in the ester radicals.  Reaction temperatures between 100 and 250 DEG C. are preferred and the silicic acid ester by-product may be distilled off from the amine-borine or aminoborine.  Solvents or diluents such as aliphatic or aromatic hydrocarbons may be used or an excess of the silicon hydride compound can be a diluent.  Examples describe the preparation of triethylamine-borane from methyl borate, triethylamine and monosilane or diethylsilane.

Title: Improvements in magnetic amplifiers
IPC: G05D23/22
Filed: 1959-09-03
Abstract: 901,336. Magnetic amplifiers. FOXBORO CO. Sept. 3, 1959 [Sept. 11, 1958], No. 30168/59. Class 40 (9). The whole of the output current of the second stage of two stages of a magnetic amplifier is fed back to a winding on the first stage. This is applied to the third and fourth stages 28 and 30 of a four-stage magnetic amplifier, as shown. Stages 28 and 30 are auto-selfexcited full-wave amplifiers supplied from centretapped windings 172, 188 of mains transformer 32. The output of stage 30 is smoothed at 192 and supplies a low impedance load 22 in series with a negative feed-back winding 196 on stage 28. Stages 28 and 30 are stabilized by the looped windings 200, 202, and each stage has a short-circuit winding 208, 210. The first stage 24 is provided with input from a thermocouple 16 over a smoothing choke 38, voltage limiting diodes 53, 54, and a temperature-compensating bridge 55, 56, 57, 58 in which resistor 55 is temperaturedependent. The bridge is energized from the power supply provided by centre-tapped winding 76 of the mains transformer 32 with Zener diodes 66, 68 and 69, giving voltage regulation. A temperature-dependent resistor 64 provides compensation in a bias supply to the stages 26 and 28, while bias to stage 24 is uncompensated. Output from the second stage 26, which is fullwave auto-self-excited from centre-tapped winding 136 of the mains transformer, is fed to the input to stage 28 in series with a resistor 58 connected in the thermocouple and compensating bridge input circuit, thereby contributing negative voltage feed-back. The output of the first stage 24 forms a half-wave balanced output circuit fed from winding 90 of mains transformer 32. Positive rate feed-back is applied to stages 24 and 26 with windings 118 and 146; stage 26 also having positive feed-back to winding 144. For an input of a few millivolts the amplifier is said to give an output of the order 10 to 50 milliamps. Specification 901,335 is referred to.

Abstract: 1,019,996. Circuits employing bi-stable magnetic elements. SPERRY RAND CORPORATION. Aug. 9, 1962 [Sept. 22, 1961], No. 30554/62. Heading H3B. The magnetic cores of a matrix are operated under the influence of a bias field between a stable saturation point 48 on the hysteresis curve shown and a " time limited " point 50. By " time limited " it is meant that the duration of the driving field is insufficient to take the flux from one saturation state to the other. In the embodiment described, Fig. 5 (not shown), bipolar read-write signals 62, 72 on a word line are combined with the bias 60 or write " 1 " signal 70 on the digit line. The limited duration write signal 72 and the bias signal 60 together drive the core flux to point 66 from which the bias field alone returns it to point 68 to record a " 0." To write a " 1 " the bias is removed and the limited duration write signal 72, together with a write " 1 " signal 70 in the digit line, causes the magnetization to reach point 74 before the restored bias 60 returns it to point 50 to store a " 1." The read signal 62 drives the magnetic state of a core to point 58, thus producing an output pulse in a sense line. In the embodiment described transformer coupling is used for the word lines and information may be re-written after readout so as not to destroy the information on reading. The sense windings are wound for noise cancellation.
