Title: Modified aminoplastic resinous compositions
IPC: C08L61/20
Filed: 1956-01-12
Abstract: An aminoplast composition comprises (1) an uncured reaction product of an aldehyde and a monomeric compound containing two or more amidogen groups each having at least one hydrogen atom attached to the amidogen nitrogen atom, (2) an alpha alkyl-D-glucoside wherein the alkyl group contains 1 to 4 carbon atoms, and (3) a compound of the formula <FORM:0790034/IV (a)/1> wherein R is an organic radical, X is SO2 or CO, and R1 is hydrogen or an alkyl, alkylol, aryl or acyl radical, the glucoside and methylol compound together constituting from 1 to 35 per cent by weight of the composition.  Examples of methylol compounds are amides, sulphonamides and imides, e.g. N-methylol-toluene sulphonamide, -benzamide, -phthalimide, -toluamide, -stearamide, -succinimide, -p-cymene sulphonamide, -xylene sulphonamide and -1,2,3,4-tetrahydronaphthalene sulphonamide. The ratio of the glucoside to methylol compound should be within 25 : 75 to 75 : 25 by weight.  The methylol compound may be formed in situ during the formation of the resin or may be added as such to the resin.  If the resin is a melamine-formaldehyde product, the addition should be to the liquid resin.  The glucoside may be added at any time prior to the cure of the composition, and may be added separately to a portion of the resin and the two mixtures combined. The specific examples relate to melamine resins, but the resin may be prepared from urea, thiourea, dimethylol urea and alkyl ethers thereof, polymethylol melamines and their alkyl ethers, methyl urea, phenyl urea, allyl urea, guanyl urea, guanyl thiourea, dicyandiamide, guanidine, biguanide, diaminodiazines, guanazole and other diaminotriazoles.  Instead of formaldehyde there may be used paraformaldehyde, hexamethylene tetramine, paraldehyde, acetaldehyde, propionaldehyde, butyraldehyde, benzaldehyde, furfural and mixtures thereof.  The compositions are primarily intended for use in decorative laminates, when they are employed as solutions or dispersions in a mixture of water and a lower alkyl alcohol in concentrations of about 20 to 60 per cent.  The compositions may also be used for moulding.  Curing agents, colouring matter, mould lubricants and fillers may be added, particular examples being p-toluene sulphonic acid, phthalic acid and anhydride, and benzoic acid; zinc, calcium and glycerol stearates; alphacellulose, wood flour, walnut shell flow, calcined or natural asbestos fibres or powder, silicon carbide, carbon black, graphite, diatomaceous earth, slate dust, ground cuttings of silk, rayon, nylon or glass cloth, and ground cork.

Abstract: 824,102. Automatic steering control systems. SUD-AVIATION SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. Jan. 13, 1956 [Jan. 21, 1955], No. 1270/56. Drawings to Specification. Class 38 (4). [Also in Group XL (c)] In an aircraft automatic pilot craft deviations are transformed into electrical signals which are transmitted by radio to a remote station where the signals are combined to produce further signals which are transmitted back to the aircraft by radio to control it. The invention is applied both to an aircraft having rudder, elevators and ailerons and to an aircraft having three rudders 120 degrees apart. Instruments on the aircraft transform the following variables into electrical signals which are transmitted over a multi-channel frequency-modulated radio link to a station remote from the aircraft :-(a) airspeed; (b) rate of pitch; (c) rate of roll; (d) rate of yaw ; (e) acceleration along the pitch axis; (f) acceleration along the yaw axis; (g) position of each control surface. Suitable instruments having variable voltage, inductance or capacitance type pick-offs are described. At the remote station the received signals are combined in various proportions and in various senses in an electronic or mechanical computer to produce three resultant signals which are then transmitted to the aircraft over a second multi-channel radio link to control each of the three control surfaces so that a set course and altitude is automatically maintained. The control surfaces are operated by hydraulic servomotors controlled by pilot valves, operating solenoids of which are energized under the control of differential electromagnetic relays. A control column and steering swing-bar is provided at the remote station so that a human pilot there can set the desired course and altitude by producing electrical signals which are combined with the other signals in the computer. By operating switches at the remote station the human pilot may also send signals over the second radio link to operate landing gear, flaps, air or wheel brakes or fuel controls. Signals indicating the position of such apparatus are also transmitted over the first mentioned radio link so that, together with the other signals, they may serve to operate indicators and instruments on an instrument panel provided for the benefit of the human pilot at the remote station. Specification 824,101, [Group XXXVIII], is referred to.

Title: Improvements in and relating to electrical apparatus for automatically controlling avariable
IPC: G05D23/27
Filed: 1936-01-15
Abstract: 456,795. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Jan. 15, 1936, No. 1323. Convention date, Jan. 16, 1935. [Class 38 (iv)] Temperature &c.-In apparatus for the control of a variable wherein triodes, or like discharge devices, are rendered conducting or non-conducting by change in the grid or like control voltage, an opposed voltage in the grid or like control circuit is varied according to the correction effected so that the discharge devices are restored to their initial state and hunting is avoided. In a rotary kiln 10 the temperature of the contents is controlled by a photo-electric cell 18 controlling the grid potential of an amplifier 19 the output circuit of which includes resistance 33. The rate at which the contents travel through the kiln is varied to control the temperature by changing the speed of a commutator motor 12 rotating the kiln. A reversible pilot motor 16 adjusts the commutator brushes as required, relays 22, 23 supplied through triodes 20, 21 being provided. A generator 39 circulates a current in a resistance 36 to give a potential drop therein proportional to the speed of the kiln. The grid circuit of the triodes 20, 21 includes a portion of resistances 28, 29, resistance 22 and resistance 36. The first are adjusted so that the valve 20 is non-conducting and the valve 21 is conducting when the temperature in the kiln is normal, i.e., when a normal current is passing in the resistance 33 in the anode circuit of the amplifier 19. Any variation in the potential drop in resistance 33 due to temperature variation will then cause relay 22 or 23 to close its contact and adjust the speed of the kiln, but the change in speed will vary the current in the resistance 36 so that the potential drop therein equalizes the potential drop in resistance 33 and the valves 20, 21 are restored to their original condition, notwithstanding the speed adjustment. Hunting or over regulation is thus prevented.

V. ; Haddonfield Manor, Haddonfield, New Jersey, U.S.A.) Jan. 18, 1932, No. 1496. Convention date, Jan. 16, 1931. [Class 40 (v).] A radio receiver comprises a local-distance control, in which resistances are inserted into circuit with loose-coupled tuning coils, and a volume control, the two controls being operated by a single handle. Fig. 1 shows a super-heterodyne receiver comprising a radio-frequency amplifier 7, first detector 9, oscillator 17, two intermediate-frequency amplifiers 31, 33, second detector 39 and push-pull output stage 72. Screen grid voltage for valves 7, 9, 31, 33 is obtained from resistance 53, while control grid bias for valves 7, 31 is derived from resistances 57, 59 the latter being variable and constituting the volume control of the receiver. The coupling between the first detector 9 and amplifier 31 is made loose by spacing apart the coupled coils 23, 27 and interposing a copper disc 24. For local reception quality is improved at the expense of selectivity by a localdistance switch 69, which inserts a high resistance 74, across the tuned circuit 25, 23 and a low series resistance 76 in the circuit 27, 29. In its other position, the switch open-circuits 74 and short-circuits 76 ; alternatively the switch may have a third position cutting out one resistance only. The switch is unicontrolled with the volume control 59 as shown in Fig. 3. Fig. 2 shows the arrangement of the coils 23, 27 and copper disc 24 on an insulating former 26. The disc 24 may be bent down at the edges if increased coupling is required. Instead of one series and one shunt resistance for the coupled circuits 23, 27; two series resistances with single control may be used as shown in Fig. 2, the volume control being actuated by the same handle. Coupling arrangements similar to the device of Fig. 2 may be employed for coupling coils 35, 37, 41, 43 with the omission of the disc 24. In the latter case one of the pins 28, which are normally of copper or brass to reduce losses, may be of iron.
