Title: Improvements in or relating to automatic flight control systems for aircraft
Inventor: POLLAK HEINZ
IPC: G05D1/06
Filed: 1963-01-18
Abstract: 1,065,695. Automatic control of aircraft. SMITHS INDUSTRIES Ltd. Jan.17, 1964 [Jan.18, 1963], No,2216/63. Heading G3R. In a system in which the pitch attitude of an aircraft is automatically controlled by a signal to produce a flare-out in pitch during landing, the signal is also responsive to airspeed in such sense that changes in attitude with airspeed are such as to compensate for the change in lift which would otherwise occur. In Fig.2, the elevators 41 of an aircraft are automatically controlled by a rate-rate servo-system in which electrical signals from a rate gyro 36 are applied through a phase advancer 37 and magnetic amplifier 35 to operate a servomotor 38 controlling elevator actuator 40. Rate feedback to amplifier 35 is derived from a tachometer generator 39 associated with servomotor 38. During automatic landing, the pitch attitude of the aircraft is controlled by signals from a radio altimeter (not shown) which are amplified by magnetic amplifiers, have differential and/or integral components added by resistance-capacity networks, are limited by diode limiters, and finally applied to amplifier 35 at 15 so that the aircraft makes an exponential descent. To counter the effect of speed variations on altitude of the aircraft, differentiated electrical signals from an airspeed detector (not shown) are filtered to reduce noise, and applied to amplifier 35 at 33 so that the pitch of the aircraft is adjusted to maintain the same lift despite change of airspeed. There are references to (a) additional control of pitch attitude in dependence on time (b) use of a position instead of a rate servosystem (c) control of elevons instead of elevators (d) guidance in azimuth by a localiser radio beam (e) maintenance of constant airspeed by automatic control of engine throttles.

Title: Magnetic recording material
IPC: C08K5/45
Filed: 1963-01-18
Abstract: 991,676. Magnetic recording members. GEVAERT PHOTO-PRODUCTEN N.V. Jan. 18, 1963 [Jan. 22, 1962], No. 2256/63. Heading H1H. A magnetic recording member is formed by depositing on a substrate a dispersion of magnetic particles in a solution of a fully latent polyisocyanate and a binder which reacts above a certain temperature with isocyanate groups, then evaporating the solution below the reaction temperature and finally heating above the reaction temperature allowing the isocyanate groups and the binder to react. By fully latent polyisocyanate is meant the reaction product produced by the addition of a compound containing an active methylene group to any isocyanate group of a polyisocyanate compound. From this latent polyisocyanate the free polyisocyanate is regenerated by heat between 100‹ and 200‹ C. The magnetic particles are preferably oriented by a magnetic field during the evaporation process and the member is calendered before or during the chemical reaction. The substrate may be stretched polyethylene terephthalate coated with a copolymer of acrylonitrile and vinylidene chloride as in Specification 991,675. The binder may be of thermoplastic macromolecular compound containing groups which react with isocyanate groups, such as polymers containing free hydroxyl, carboxyl, amino or sulfhydroxyl groups. Suitable polyhydroxy compounds include cellulose esters and cellulose ethers containing free hydroxyl groups such as nitro-, acetyl-, propionyl-, butyryl-, acetylbutyryl-, benzyl- and ethylcellulose. And also partially saponified polyvinyl esters, soluble reaction products of polyamides and epoxy resins and polyesters containing hydroxyl groups, such as the soluble reaction products of polyesters containing hydroxyl groups with polyisocyanates. Other suitable binders are polyvinyl acetals with free hydroxyl groups, such as the non-stoichiometric reaction products of polyvinyl alcohol and butyraldehyde. Solvents for these binding agents are chlorinated lower aliphatic hydrocarbons, lower aliphatic alcohols and aromatic hydrocarbons such as toluene. Latent polyisocyanates which may be used include the addition products of lower alkyl acetoacetates, such as ethyl acetoacetate, and polyisocyanates, such as 1,4-cyclohexyl di-isocyanate or 1,6-hexane di-isocyanate. However these cause pores and irregularities in the film due to the escape of the volatile alkylacetoacetates. This can be overcome by using a compound of, for example, 2,4-toluene di-isocyanate with an ester of malonic acid or acetyl acetic acid and a polyalkylene glycol where Z is alkylene, such as ethylene or isopropylene; R is a group not reacting with isocyanate; n is an integer from 1 to 50. The Specification gives four quantitative examples for making recording tapes.

Title: A process for the pigmenting of prepolymers of polyurethanes
IPC: C08K9/04
Filed: 1964-01-20
Abstract: A mixture comprises a pigment and an hydrolysable compound which is hydrolysed substantially completely in the presence of water.  The hydrolysable compound may be an alkyl borate, aluminium alkoxide, alkyl titanate, difurfuryl ether, ethyl orthoformate or ethyl or trosilicate.  Methyl lactate or ethylene glycol diformate may also be used by mixing them with compounds capable of reacting with the acids resulting from their hydrolysis e.g. alkyl titanates.  Many pigments are specified e.g. carbon black, rutile, iron oxide and barium sulphate.ALSO:Polyurethane prepolymers containing terminal -NCO groups are pigmented by mixing said prepolymer with a pigment and a compound which is hydrolysed substantially completely in the presence of a substantially stoichiometrically equivalent amount of water to form a compound containing at least one -OH, -SH or N-H bond, said compound being added in an amount at least stoichiometrically equivalent to the water present in the pigment.  A pre-mixture of pigment and hydrolysable compound may be made and then mixed with the prepolymer. The hydrolysable compound may be: an alkyl borate, alkyl titanate, difurfuryl ether, ethyl orthoformate or ethyl orthosilicate. Methyl lactate and ethylene glycol diformate may also be used by mixing them with compounds, e.g. alkyl titanates capable of reacting with the acids resulting from their hydrolysis. In this case the pigment is premixed with the aforementioned mixture of compounds before its incorporation into the prepolymer.  To prevent blocking of the -NCO groups of the prepolymer by the -OH, -SH or = NH groups formed by the hydrolysis, a mono or polyisocyanate which is more reactive with the free -OH, -SH or = NH groups than the -NCO groups of the prepolymer may be added to the mixture.  A preferred isocyanate is diphenyl methane 4,41-diisocyanate.  The use of the isocyanate as binding agent may be avoided by using as the hydrolysable compound one that liberates an alcohol which is only very slightly reactive with -NCO groups, e.g. t-butyl alcohol from the hydrolysis of tetra-t-butyl titanate.  In a typical Example (2) uncoated rutile TiO2 was mixed with diotyl phthalate and secondary aluminium butylate and a solution in methyl-isobutylketone of a prepolymer from toluene diisocyanate and oxypropylated trimethylol propane and polyoxypropylene glycol. Many pigments are specified, e.g. iron oxide red, iron oxide yellow, iron oxide black, phthalocyanine green, carbon black, barium sulphate and titanium white.

Title: Improvements relating to arrangements for controlling the access of a plurality of equipments to a common apparatus or circuit
Inventor: LONG DOUGLAS PERCY
IPC: H04Q3/42
Filed: 1961-01-23
Abstract: 927,410. Automatic exchange systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 27, 1961 [Jan. 23, 1961], No. 2619/61. Class 40 (4). In an arrangement for testing the availability of a common apparatus, each equipment of a plurality associated with the apparatus is provided with a capacitor which (when the equipment requires the use of the apparatus) is periodically charged and then discharged through a circuit comprising a test relay shunted by similar test relays in each of the other equipments, the arrangement being that if the common apparatus is busy the greater part of each discharge is through the shunt circuit, whereas when it becomes free the discharge is then substantially through the associated relay so that the latter is operated and hence seizes the common apparatus. The invention is applied to the case where a plurality of registers require access to a control circuit common to a number of selectors. When a register (Fig. 1a) requires the use of the control circuit (Fig. 2), a contact ax therein operates to complete a self-interrupting circuit for the slow-operate slow-release relay AG and capacitor AC2 is thus periodically connected to a test relay AT, which is thereby operated and locks to negative battery in the control circuit if the latter is idle. However, if another register is already connected up, i.e. test relay BT is up, capacitor AC2 discharges through the low resistance holding winding II of BT and AT remains down until the control circuit is free. If contact z is open then none of the registers can gain access to the control circuit.
