Filed: 1950-02-02
Abstract: 804,905. Electric analogue calculating systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Jan. 19, 1951 [Feb. 2, 1950], No. 2679/50. Class 37. In a computing apparatus for evaluating the rate of change of one variable with respect to a second variable, a tightly coupled inductive potentiometer forms the primary of a transformer, the voltage at the secondary of which represents the required rate. Impedances connect voltage storage devices to contacts along the length of the potentiometer which are moved continuously along the potentiometer from the centre point such that their positions represent values of the second variable. Alternating current voltages of the same phase, or the storage device have amplitudes representative of values of the first variable which correspond to the values of the second variable represented by the position of the corresponding taps. As shown, the tightly coupled potentiometer is scanned by a series of sliding contacts 5 ... 8 in the downward direction. The contacts are fed from storage units 9 ... 12, through resistors 13 ... 16, with alternating voltages representative of values of the first variable. As the lower tap 8 leaves the potentiometer a fresh tap commences the downward scan at point 2 and is simultaneously connected to a storage unit. The output at winding 17 represents the required rate of charge. Specification 802,799, [Group XXXVIII], is referred to.

Title: Improvements in and relating to aircraft rate of climb indicating instruments
IPC: G01P3/62
Filed: 1956-01-27
Abstract: 800,046. Aircraft instruments. SPECIALTIES, Inc. Jan. 27, 1956 [Jan. 28, 1955], No. 2794/56. Class 4. [Also in Group XIX] A rate of climb indicator for aircraft comprises a barometric capsule 19 housed within a closed container 18, the base 19a of the capsule being fast with the container and having a connection 20 with a static pressure line 21. The interior of container 18 communicates with static pressure air through a capillary opening 22 so that movement of diaphragm 19b of the capsule gives an indication of the rate of climb of the aircraft. Such indication, however, lags behind the instantaneous rate of climb due to the metering effect of capillary 22 and to overcome this disadvantage the signal from the capsule 19 is combined in an adding device 24 with a further signal from an accelerometer 10, the combined output from device 24 being used to operate a rate-of-climb indicator 26. The accelerometer comprises a vertically movable mass 10, balanced by a spring 11 and damped by a dashpot 15. In operation, during a climb, the mass 10 will be caused by the vertical acceleration of the aircraft to move downwardly which results in an immediate output, representative of rate of climb, fed to adding means 24. The signal so derived is transient, but before it decays the aircraft will have moved upwardly into relatively less dense atmosphere so that a further signal will be derived from the capsule 19 to complement the decaying signal from mass 10. When the aircraft levels off a negative acceleration will be present in mass 10 which will reverse its signal to means 24 and cancel the enduring erroneous signal from capsule 19. Embodiments are described wherein the coupling between mass 10 and capsule 19 is pneumatic and provision is made to cancel erroneous signals resulting from the effect of sustained accelerations experienced in turns. Further, a gyroscope may be incorporated in the instrument to furnish signals, which are functions of pitch and bank angles of the aircraft, to control the movements of mass 10. In a further embodiment the capsule 19 and mass 10 are mounted in a common housing mounted in the aircraft for banking movement under the control of a servo motor and follow up unit energized by a gyroscope whereby movement of the housing with reference to the instrument panel of the aircraft provides an indication of bank angle.

Title: Improvements in or relating to the production of polymeric products from styrene andunsaturated fatty compounds
IPC: C09D125/14
Filed: 1951-02-07
Abstract: <PICT:0709011/IV (a)/1> Styrene (4 to 6 parts) and one or more unsaturated fatty compounds (6 to 4 parts) are co-polymerized by continually passing the mixture through a reaction zone heated to between 210 DEG  and 270 DEG  C. and maintained within this range by the removal of heat developed during the reaction, under a pressure at least sufficient to maintain the reaction mixture in the liquid state, e.g. 25 to 100 atmospheres, the contact time within the zone not exceeding 120 minutes and being such that 30 to 90 per cent. by weight of the styrene is reacted.  The fatty compounds may be drying oil unsaturated fatty acids or partial or full esters of such acids with polyhydric alcohols.  Specified esters are (A) raw or partially polymerized conjugated drying oils such as oiticicia, china wood, tung or dehydrated castor oil and isomerized oils from B and C, (B) unconjugated drying oils such as linseed or perilla, (C) esters of glycol, pentaerythritol and sorbitol with unconjugated fatty acids derived from whale, sardine, herring and menhaden oils, (D) semi-drying oils such as soyabean and sunflower oils and (E) esters of mannitol, pentaerythritol or sorbitol with fatty acids derived from A, B or D.  The unsaturated fatty acids which may be used are those derived from the oils or esters above.  Up to 50 per cent. of a conjugated oil is added when using semi-drying oils or their acids and sulphur may be present in up to 0.5 per cent. of the fatty component.  An inert solvent such as xylene or white spirit may be used and excess styrene and the solvent may be removed after reaction by a continuous stripping still.  The styrenated fatty acids produced may be reacted with a polyhydric alcohol, e.g. glycerol, and a polybasic acid, e.g. phthalic or maleic acid or anhydride, to produce alkyd resins.  Esters may also be produced by reaction with glycerol alone.  Referring to the drawing, styrene and the fatty compounds are separately pumped from supply p  lines 13, 14 into a mixer 17, and then through a reactor coil 19, surrounded by boiling liquid 21, vapour from which is condensed in reflux condenser 24 and may be reboiled in the heater 22.  The products pass through a needle let-down valve 26, and then either through a cooler 28, to storage or to a continuous stripping still 30, and then through pipe 32 to the cooler and storage.  Recovered unreacted styrene is recycled.  The liquid 21, e.g. a mixture of toluene and alkyl naphthalenes, both brings the reactants to temperature and acts as a cooling means to maintain the temperature in the range required.  Solutions of the products in white spirit and/or xylene may be mixed with metal naphthenate driers and titanium dioxide to form cooling compositions. Specifications 573,809, 573,835, 611,109, 616,044 and 622,948 are referred to.
