Filed: 1939-03-31
Abstract: 530,509. Radio direction-finding. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MEREDITH, F. W. March 31, 1939, No. 10131. [Class 40 (v)] [Also in Group XXXV] Relates to aircraft direction-finders for homing on to a ground transmitter of the type in which the directional aerial is stabilized in azimuth by a turn detector, e.g. a gyroscope, in order to reduce the curvature in the homing path in the presence of side winds. According to the present invention the angular correction applied to the aerial is n # where # is the change in the heading of the aircraft and n is between 0 and 1, e.g. 0.7 to prevent hunting. As shown the direction-finder comprises loop and open aerials 12 and 11 and a receiver 10 controlling a left-right indicator 15 and a relay 16 controlling an automatic pilot 17. Initially the loop is set athwart ship and the aircraft orientated to give a zero deflection on indicator 15 and the gyro 18 is then coupled via a servo motor 24 to the loop aerial by actuating an electromagnetic clutch 22. In a modification, Fig. 2 (not shown) the rudder is controlled by the servo motor which is mechanically coupled to the gyroscope via a differential gear one input of which is actuated by a reversible motor controlled by the relay.

Title: Process and apparatus for removing oil from condensation waters
IPC: B01D17/02
Filed: 1921-04-07
Abstract: 161,942. Gail, J. B., and Adam, N., (trading as Soc. J. B. Gail et N. Adam). April 15, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Purifying liquids; filters with loose filtering- materials.-To remove oil from water of condensation the water is treated with an alkaline and an acid reagent which will react to form a metallic hydrate that will envelope and carry down the oil. Carbonate of soda and perchloride of iron are preferably used. Suitable apparatus comprises vessels 5, 6 containing the reagents in solution. The solutions are displaced from the vessels 5, 6 at an equal rate by water passing to the vessels through adjustable orifices from a vessel 17 in which a constant liquid level is maintained by a float valve. The solutions mix with the water to be treated in a cylinder 30, situated centrally in a compartment 2 of a tank 1, and' the mixture passes down a pipe 29 to the bottom of the compartment where the precipitates settles. The water overflows from the compartment 2 through a receiver 31 and pipe 32 to the bottom of a compartment 3 in which it is filtered upwards through a bed of wood fibre. It is finally passed to a third compartment containing gas coke over which it is distributed by a system of perforated branch pipes. Discharge takes place through a pipe 40, open at the top and having an outlet branch 41, so that the liquid level in the last compartment is such that, while the water trickles over the upper portion of the coke, the lower layers are flooded. A modified form of apparatus is described in which the water to be treated is supplied intermittingly from a siphon cistern to the mixing chamber, which is in the form of a bell and has a tapered sediment receiver below. The water passes upwards through the bell and is then directed downwards towards the bottom of the main settling-vessel by a pipe which surrounds the bell. There is a filter of wood fibre in the upper part of the settling vessel.

Title: Preparation of a therapeutically useful heterocyclic sulphonamide derivative
IPC: C07D239/69
Filed: 1945-04-24
Abstract: 2-(p-Aminobenzenesulphonamido)-4-methylpyrimidine is obtained by condensing a p-substituted benzenesulphonyl guanidine, wherein the p-substituent is a free amino group or a substituent capable of conversion into an amino group by a method known per se, with a 1-halogeno-1-butene-3-one and thereafter, if necessary, converting the p-substituent into a free amino group.  Specified p-substituents are acylamino, alkylideneamino, nitro, nitroso, azo, azido and carbamido.  Condensation is effected optionally in the presence of a solvent, preferably using a condensing agent such as an alkali alcoholate, mineral acid, acid anhydride or nitrogen base.  In examples: (1) p-acetylaminobenzene sulphonyl guanidine in sodium ethoxide solution is heated under reflux with 1-chloro-1-butene-3-one, and the residue, diluted with water, is neutralized with acetic acid and hydrolysed by boiling with aqueous caustic soda; (2) p-acetylaminobenzene sulphonyl guanidine and pyridine are heated under reflux during the gradual addition of 1-chloro-1-butene-3-one and the residue is dissolved in 2N caustic soda, the alkali filtrate being refluxed and the product precipitated by acetic acid; (3) p-acetylaminobenzene sulphonyl guanidine and 1-chloro-1-butene-3-one are added to sodium benzylate, the mixture being heated under reflux, diluted with water and neutralized; and (4) p - aminobenzene sulphonyl guanidine is stirred whilst heating under reflux with sodium ethoxide solution, 1-chloro-1-butene-3-one is added and the mixture finally filtered and the product precipitated by acetic acid.  The Specification as open to inspection under Sect. 91 refers also to the use of acetals of 1-halogeno-1-butene-3-one, or their derivatives in the enolic form. This subject-matter does not appear in the Specification as accepted.

Abstract: 809,593. Friction clutches. FERGUSON RESEARCH Ltd., H. June 3, 1955 [April 9, 1954], No. 10508/54. Class 80 (2). A motor vehicle disc clutch 13 is engaged by a single central spring 41 acting between the usual presser-plate 37 and an enclosing flared tubular shaft 18 which connects the engine flywheel 12 to the crankshaft 11 through a laminated disc coupling 23. The clutch is disengaged by applying pedal - controlled hydraulic pressure to a piston 43 on the remote end of a clutch-withdrawal rod 26 passing centrally through the aligned hollow input and output shafts 35, 25 of the associated changespeed gear, to bear directly on the presserplate 37. Disengaging thrust is taken by a bearing 46 supporting the flywheel 12 in the front wall of the gear-case. Alignment of the presser-plate 37 is maintained by sliding bearing surfaces between its hub and the shafts 18, 35. The final output wheel of the changespeed gear drives an inter-axle differential gear 30 driving a front axle 17 and, through a connection 29, a rear axle. Additional one-way driving connections 31, 32 limit possible overrun of the axles as described in Specification 731,938. Specification 773,595 also is referred to.

Title: Improvements in continuously variable frietion gearing
IPC: F16H15/22
Filed: 1928-04-10
Abstract: 306,752. Robertson, J. H. April 10, 1928. Grant of Patent refused. Variable-speed friction gearing suitable for motor-vehicles comprising a friction driven member k movable transversely with respect to a driving-member c is operated automatically in accordance with the speed, or with the torque, or in accordance with both jointly. The member c turns with a shaft a fixed in position and has a conical gear face c<1> which is thrust out axially so as to draw the member k inwards and control the speed by a centrifugal governor such as that described in Specication 306,751, [Class 57, Governors &c.]. The surface c<1> is box-shaped and has a feathered connection at b<1> with a rigid cylindrical box b within which is a loose cam ring f turned against springs d by a pivoted centrifugal weight g. The driven member k is supported on a short shaft i, which moves parallel to itself being carried upon an arm j pivoted at j<1>, a universally jointed shaft h transmiting the drive. A toggle link m comprising a spring in compression tends to hold the arm displaced eccentrically, and the rearward wedging thrust on the member k is supported by a buffer link n.' The torqueresponsive control is a balance between the axial thrust of cone c<1> pulling member k inwards and the reaction of the drive by the same cone tending to thrust the same member outwards. An imposed manual control is effected by applying axial thrust to the other end of the buffer link n, and a hand-lever for doing this is described. When this lever is withdrawn to disconnect the drive, it may be coupled to a control for operating a suitable auxiliary reversing-gear. In the arrangement shown, the member k has two friction surfaces k<1>, k<3> of different coefficients, as described in Specification 306,753.

Abstract: 1,076,072. Signal level detector. ENGLISH ELECTRIC CO. March 11, 1966 [March 12, 1965], No. 10619/65. Heading H3T. [Also in Division H2] A signal level detector comprises means for producing from an alternating input signal a unidirectional cyclically varying signal having maximum and minimum values proportional to the peak value of the alternating input signal, and a switching device to which the unidirectional signal is applied, which device assumes one state upon the maximum value exceeding a first threshold and a second state upon the minimum value falling below a second threshold. The unidirectional signal is formed by the combination of a full-wave rectified version of the input signal, provided by diodes 8, 9 and a similar signal of 90 degrees phase difference obtained from phase-shift circuit 10-13 and full-wave rectifier 14, 15. The signal is then applied to Schmitt trigger 17, which circuit has unequal collector load resistors 20, 21, so that transistor 18 is switchedoff when the maximum of the unidirectional signal exceeds a first threshold, and is not turned on until the minimum falls below a second, lower threshold. The diodes 8, 9, 14, 15 may be replaced by transistors connected in emitter-follower configuration (Fig. 3, not shown). A polyphase input signal may be employed, in which case the phase-shift network is dispensed with, since the rectified input will have the cyclic form necessary.
