Title: Navigation-aid apparatus for aircraft
IPC: G05D1/06
Filed: 1955-11-18
Abstract: 776,595. Controlling aircraft. SPERRY RAND CORPORATION. Nov. 18, 1955 [Dec. 6, 1954], No. 33038/55. Class 4. [Also in Group XL(c)] An aircraft navigational aid includes means for manually or automatically utilizing a radio glide path or for establishing level flight conditions. A switch is provided for disconnecting the glide path signals and im mediately substituting signals calling for level flight at the altitude reached ; after a pre-set time or when the craft has reached a pre determined speed the level flight signal is replaced by signals [for flying upwards As shown, signals from the glide path receiver 5 are fed to modulator 6 to produce a control signal fed over switches 12 and 17 for mixing with a vertical attitude signal from gyroscope 7 in mixer and rectifier 4. The output of unit 4 is fed to operate the horizontal pointer 2 of cross pointer indicator 1 and/or to control automatic mechanism 51 operating on the elevators. If control 11 is operated switches 12 and 13 are moved to other contacts and the glide path receiver signals are replaced by a signal from altimeter 9 tapped off across potentiometer 16. The second contact of switch 13 energizes clutch 10 associated with the altimeter so that its signals call for (or produce) flight at the altitude reached when control 11 is changed over. If landing down a glide path is being attempted and it becomes necessary for emergency reasons to fly up again as soon as the air speed makes it safe to do so, switch 20 is operated. This immediately disconnects the receiver 5, energizes clutch 10, and feeds the whole of the signal from altimeter 9 calling for level flight over switches 21 and 17 to mixer 4. Switch 21 is controlled by relay 22 in circuit with now closed switch 19 and device 24. In the latter, pressure bellows 26 are controlled by dynamic air pressure due to the speed of the craft and when the craft speed is high enough move contact 35 off insulating segment 31 onto conductive segment 32. This completes the relay circuit and disconnects the altimeter signal from mixer 4 and replaces it by a manually pre-set fly-up signal from generator 35. In order to avoid unsafe angles of climb power monitors 39 and 40 on each of the engines are provided and, in the event of engine failure, these insert resistors 43 or 46 in series with load resistor 34 to form a potential-divider reducing the fly-up signal. If desired the device 24 may be replaced by a thermal time-delay unit of the bi-metallic strip type, Fig. 2 (not shown), to allow a fixed time delay, during which the craft's speed can be increased, before fly-up signals are applied. Specifications 663,913 [Group XXXVIII] and 691,017 [Group XL(c)] are referred to.

Title: Improvements in or relating to the manufacture of paper from artificial fibres
Filed: 1959-09-30
Abstract: 891,809. Pulp and paper comprising artificial fiibres. SOC. RHODIACETA. Sept. 30, 1959 [Oct. 2, 1958], No. 33203/59. Class 96. In preparing paper pulp having a pH between 2 and 3, fibres of a synthetic linear polymer, e.g. mixed with cellulosic fibres, are dispersed in water in the presence of gelatine. The pH may be brought into the required range by adding hydrochloric acid and, if desired, monopotassium phthalate. The pulp is brought to a consistency of about 1% and made into paper on a screen or wire, the paper is cold-pressed at a pressure of 10 kg. per sq. cm., then dried and conditioned. According to Example I, a mixture of fibres containing 10% by weight of polyhexamethylene adipamide fibres and 90% of refined pinewood pulp is dispersed in cold water in the presence of 4% of gelatine, computed on the total dry weight of the fibres, and the pH of the resulting pulp is brought to 2.5. According to Example II, a tow of polyhexamethylene adipamide filaments is impregnated at 25‹ C. with an aqueous 10% solution of gelatine so that the filaments retain 44% of their weight of gelatine. The tow is then dried and cut into fibres. A mixture comprising 20% of these fibres and 80% of refined pinewood pulp is dispersed in water at pH 2.5. According to Example III, a mixture comprising 50% of polyethylene terephthalate fibres and 50% of refined white kraft cellulose pulp is dispersed in water in the presence of 15% of gelatine, computed on the total weight of fibres, and the pH of the resulting dispersion is brought to 2.5. Paper made from pulp prepared according to the invention has improved strength, when compared with paper made from similar pulp having a pH of about 6.

Patent GB-941016-A (GB)
Title: A process for the preparation of alcohols
Inventor: WRIGHT WILLIAM ERIC
Filed: 1960-09-28
Abstract: Alcohols are prepared by the hydrolysis of an alkoxide or aralkoxide of a metal of Group 1, 2 or 3 of the Periodic Table in the presence of a surface active agent.  The preferred alkoxides and aralkoxides are those of zinc, aluminium, gallium and magnesium and may be conveniently prepared from the corresponding metal alkyl compound. The preferred alkoxides for use as starting materials are those in which the alkyl groups each contain 6-30 carbon atoms such as those derived from cracked wax and cracked raffinate olefines.  The metal alkyls may also be derived from olefins obtained by the Fischer-Tropsch synthesis.  The metal aralkoxides used as starting materials may also be obtained from the corresponding metal aralkyls. The surface active agent used may be anionic, cationic or monionic e.g. fatty acids, soaps, sulphuric acids or salts, alkane sulphonic acids, alkyl aromatic sulphonic acids and their salts, primary, secondary and tertiary amine salts, quaternary ammonium compounds, guanidine and thiuronium salts and preferably condensation products of an alkylene oxide with an alcohol or phenol or fatty acyl alkandamides. The hydrolysis is usually carried out by treating the alkoxide or aralkoxide with an aqueous solution of the surface-active agent.  The surface-active agent is preferably present in an amount less than 1% by weight based on the water.  In the examples an aluminium alkoxide derived from a mixture of C14-C18 cracked-wax olefines is hydrolysed in the presence of a surface active agent to give a mixture of C14-C18 alcohols.  Specifications 645,129, 763,081, 763,824, 770,707, 794,359 and 804,335 are referred to.
