Abstract: 1,143,077. Testing aircraft stall indicators. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. 20 April, 1967 [22 April, 1966], No. 17785/66. Heading B7W. An aircraft incidence sensor, which comprises a spigot 12 with either slits 13 or fins (not shown) rotated to be aligned with the local airflow, and upon reaching a given degree of rotation produces a signal for a stall warning or prevention device, is tested by apparatus comprising a sleeve 10 engaging the spigot 12 (e.g. by friction pads 11) and rotated by means (e.g. a knob 31 and alternatively a motor 18), the sleeve rotation being measured (e.g. by pointer 27 moving across scale 28), the sleeve rotation measurement being held by means (e.g. clutch and brake 181) responsive to the stall signal produced by the sensor. The pointer 27 rotates on shaft 251 with gear 26 driven by gear 20 on the output shaft 19 of the motor 18 and clutch and brake 181. To allow for clockwise rotation of a sensor spigot on the starboard side of the aircraft, and anticlockwise on the port side, the gear 19 is connected to the gear 22 on the sleeve 10 alternatively by one idler 21 or two 23, 24 mounted on plate 25. The sensor may include a phase advance network (42), Fig. 4 (not shown), to advance the angle at which the stall signal is given, in proportion to the rate of rotation of the spigot. This network is tested by using the constant speed motor 18 to drive the sleeve 10.

Title: An improved means for the transfer of heat
IPC: F25B30/00
Filed: 1924-07-29
Abstract: 242,690. Dobbs, A. C. July 29, 1924. Refrigerating, special processes for.-Relates to means for transierring heat energy from a medium at a low temperature, e.g. sea water or the atmosphere, to a high temperature medium, of the type in which the heat is first absorbed by a process of endothermic solution, e.g. using potassium nitrate and water, and then delivered to the high temperature medium, e.g. the steam evolved by evaporation, by separation of the solute from the solvent. The vapour obtained by evaporation at the surface of the solution, which constitutes a cooling mixture, is drawn through an engine or other apparatus, in which its energy is utilised, and then passed through the cooling mixture itself so that any residual heat of the vapour, including its latent heat, is transferred back to the mixture simultaneously with the reintroduction in the opposite direction, on the counter-current principle, of the solvent into the mixture. In the apparatus shown the potassium nitrate or the like is disposed within an annular receptacle 1, which is immersed in sea-water 2 and to which water is supplied from a tank 5. The receptacle 1 communicates with a boiler 3 having a non-conducting covering 4, the lower part of the boiler also containing crystals of potassium nitrate. Steam-pipes or electric heating elements are arranged in a boiler near the surface of the solution, and the heat absorbed from the sea-water in the process of dissolving the potassium nitrate is recovered when the potassium nitrate is separated again from the water and deposited in the boiler. The steam evolved in the boiler may be employed for driving a turbine 8 and then condensed, preferably in a coil 10 located in the receptacle 1. The condensate may be re-circulated from the tank at a rate regulated through the medium of a valve 12 by the pressure in the boiler, or it may be discharged at a level 11 below the apparatus not less than the height of the water barometer. In warm countries, the absorption of heat resulting from the dissolving of the potassium nitrate or the like may be made effective for cooling purposes. Also, if sea-water is supplied for the tank 5, a separation of the salts contained therein is effected in the boiler 3, and these salts may be removed at intervals.

A generator supplying a lighting load and a buffer battery is controlled by a regulator responsive to generator power output at the beginning of the change, the connections being changed to give voltage regulation at a certain changing condition. A generator 1, 2 changing a buffer battery is controlled by a field regulator 3 having two voltage coils 4, 6 and a current coil 5 connected to a relay Y. At the beginning of the change, the load current flowing through a coil 32 operates a relay Q energizing relay Y which disconnects coil 6 and inserts coil 5 in series with the load. At a predetermined voltage an opposing relay coil 33 releases the relay Q, and in turn relay Y, placing the coils 4, 6 in series and disconnecting coil 5. The generator then acts under voltage control the changing current being reduced below the operating value of the coil 32. A heavy load switched across the battery will revert the system to power regulation. In another arrangement, one relay only is employed, the contacts on relay Y being operated by the armature of relay Q. In this arrangement a cut-out is provided to disconnect the generator from the battery.

Title: Process for the treatment of textiles, paper, leather, skins and other fibrous substances
IPC: D21H17/14
Filed: 1932-06-29
Abstract: In the treatment of fibrous materials, such as textiles, leather, skins, and paper, with aqueous emulsions of organic substances for purposes such as dressing, softening, impregnating, and waterproofing, use is made of dilute emulsions, the disperse phase of which carries an electric charge of opposite sign to that on the materials treated.  The dilute emulsions are prepared from concentrated emulsions containing at least about 15 per cent of disperse phase, the dilute emulsions containing about 0,5 per cent or less of the concentrated emulsions and the volume of the bath being such that up to about 10 per cent of concentrated emulsion is taken, calculated on the weight of the material treated.  The material is left in contact with the dilute emulsion for a relatively long time, whereupon the material adsorbs the disperse phase from the emulsion. In the examples: (1) cotton is treated for 10-15 minutes with a dilute emulsion of coconut oil to which a little acetic acid has been added to give it a positive charge; (2) woollen yarn, which has been dyed with an acid dye and is positively charged, is treated for 15-20 minutes with a dilute emulsion of paraffin; (3) woollen yarn, which has been dyed without the use of acid and is negatively charged, is treated for 30 minutes with a paraffin emulsion having a positive charge due to the presence of an aluminium salt. Specification 10422/12, [Class 120 (i), Spinning, Preparation &c. for], is referred to.

Filed: 1962-03-09
Abstract: 999,183. Printed circuits. J. MICHEL. March 9, 1962, No. 18518/58. Drawings to Specification. Heading H1R. A printed circuit is made by forming a circuit pattern, including components, on an auxiliary conductive support, bonding the support on its circuit side to an insulating support and then chemically removing unwanted parts of the auxiliary support. The remaining parts of the support form an electrical screen and a reinforcement. The construction of a plug-in transistorized bi-stable circuit is described. Gold or silver contacts are first deposited through apertures in a mask formed on a thin aluminium sheet or foil. The mask is then removed and conductors of gold, silver, nickel, cadmium, chromium, rhodium, tin or alloys are next deposited electrolytically through a second mask. After removal of the second mask, further gold or silver contacts are electrolytically deposited through a third mask to form resistor terminals and capacitor electrodes. Dielectric films are now applied to form parts of capacitors. A fourth mask is now applied and resistive coatings of constantan, carbon, graphite or metallic oxides are deposited by precipitation, vaporization or fritting. A sheet or plate of phenolic or epoxy resin, melamine, or ceramic material is next attached by adhesive to the circuit side. A mask is now applied to the exposed surface of the aluminium so that unwanted parts may be etched away in a 10% sodium hydroxide solution. Modifications.-The auxiliary conductive foil may be reinforced by a detachable backing sheet. The electrolytic circuit printing may be replaced by first coating the aluminium with iron by treatment in a solution of iron perchloride, then displacing copper from a solution of copper sulphate.

Title: Improvements in and relating to hand operated indicators for displaying variable information
IPC: G09F13/32
Filed: 1943-11-09
Abstract: 585,355. Educational appliances. PAGE, C. R. Nov. 9, 1943, No. 18588. [Class 146 (ii)] [Also in Group XXXVIII] Relates to indicators of the type comprising a series of discs relatively movable to one another about a common axis and adapted when in predetermined positions to display desired information. In the embodiment shown, Fig. 5, a front disc has windows 5-11 and is connected to a back disc so forming a casing which encloses two intermediate rotary discs mounted co-axially with the front disc. A series of diagrams around the circumferential margin of the intermediate discs depict marine signals as seen at sea at night. When any particular one of these diagrams is viewed through the window 8 the corresponding meaning of the signal is seen through window 6, the type of ship showing said signal through window 5, and the number of the diagram through window 7, such data being inscribed on the rotary discs in appropriate positions. The number of the diagram corresponds to that given in an alphabetical index printed on the front disc. The first intermediate disc may be adjusted angularly to display any one of twenty-six signals through the window 8 or it may be adjusted so that a set of windows thereon coincide with the windows of the front disc whereby similar data on the second rotary disc may be viewed. Tabs 14 and 15 on the first and second intermediate discs respectively co-operate with the divisions of a circumferential scale on the front disc in order to determine the exact positions to which said rotary discs may be adjusted so that only the desired information is exposed. The windows 9, 10 and 11 expose other information regarding the Rule of the Road at sea. In another embodiment, Fig. 6, the invention is applied to an indicator for semaphore signalling. The arrangement of windows, numerals and letters on the two intermediate rotary discs and on the cover disc is such that when the arms 34, 35 attached to the rotary discs respectively are adjusted to confirm to an observed signal the meaning of said signal will be exposed through one of the windows 40 on the cover disc. The arms 34 and 35 co-operate with a circumferential scale on the back disc to determine the positions to which said rotary discs may be adjusted. Reference has been directed by the Comptroller to Specification 191,193, [Class 118 (i)]
