Title: An arrangement for winding up or unwinding spiral springs more especially for balancing sash-windows or the like
IPC: E05D13/00
Filed: 1948-03-05
Abstract: 648,989. Springs. VRIES, A. DE, and VRIES, L. DE. March 5, 1948, No. 6963. [Class 108(iii)] [Also in Group X] In an arrangement for winding up or unwinding spiral springs, more especially, for balancing sash windows &c. a twisted strip having part of its length twisted in one direction and part in the other, or a screw threaded bar with a part of righthand thread and a part of left-hand thread, is used first to twist the spring in one direction and then in the other as the strip or bar is moved relatively to the spring. Fig. 1 shows the invention applied to a window sash 1 slidably mounted in the frame 2. A tension spring 3 between the sash and frame is attached at one end to the sash at 4, and at the other end 5 to a tube 6 which is attached by a fastener 7 to the frame at 8. A torsion spring 9 within the tube 6 is fixed to the tube at its upper end, and at the lower end is fixed to a slotted bushing 10 which is mounted for rotation in tube 6 and at 11 engages the spiral member 12 which is secured to the spring 3 at 13, reverses its direction of twist at 14, and whose pitch decreases from 14 towards each end. The sash weighs 25 Kgs, and when the window is fully opened spring 3 exerts an upward force of 15 Kgs, and spring 9 is biassed so that it tends to unwind in a clockwise direction when viewed from above, and exert a rotational force. The upward vertical component of which is 10 Kgs., so that the resultant upward force is 15 Kgs. As the window is moved to the half-way position, spring 3 is stretched so that the force it exerts increases to 25 Kgs., and spring 9 is still further wound, but due to the increase in the pitch of the spiral it exerts a decreasing upward vertical force which becomes zero at point 14 where the pitch is 90 degrees. At the half-way position, therefore, the resultant upward force is again 25 Kgs., and spring 9 is biassed to its maximum extent. When the sash is further lowered spring 3 is stretched and the upward force it exerts increases to 35 Kgs. at the closed position, and spring 9 is unwound by the action of the spiral, but because the pitch of the spiral decreases spring 9 experts an increasing vertical force, in a downward direction because of the hand of the spiral, which becomes 10 Kgs. in the closed position, so that the resultant is again an upward force of 25 Kgs., the weight of the sash. The tension spring may be replaced by a compression spring in another arrangement.

Title: Improvements in radio navigating means for locating the position of a movable body
IPC: G01S1/02
Filed: 1936-03-09
Abstract: 475,027. Electric signalling systems. SJOSTRAND, H. E. March 9, 1936, No. 7020. [Class 40 (i)] [Also in Group XL] Relates to a method of utilizing the signals from one or more fixed land beacons to mark out the position and to record the course, of an aeroplane or other moving craft by the intersection of two indicator needles moving over a chart, provision being made to drive one of the two indicators in the opposite direction to the other, since it lies on the opposite side of the chart, and also to correct for any turning movement of the craft relative to the beacon station. As shown in Fig. 1, a frame aerial 10 is constantly rotated by sprocket gear 14, 15, the pick-up voltage being applied through the receivers 82, 821 to two members 32, 321 which are located on a chart 44 in positions corresponding to the geographical location of the land stations. The pointers 70, 701 are aligned in directions which correspond with the bearings of the moving craft relative to the land stations through the medium of relays 85, which are operated at those movements when the signal pick-up is a minimum. The circuit including the contact 88 and conductors 90, 91 energizes a coil and armature contained in the casing 32 and thereby rotates the needle 70 into the desired direction. The same operation takes place through the receiver 821 and member 321, the double bevel-gearing 25, 28, 281 ensuring a reversal of drive of the needle 701 necessitated by the fact that the member 321 is on the opposite side of the chart. In order to compensate for any turning movement of the mobile craft, a gimbalmounted compass needle contained in a casing 106 co-operates with a lamp and a pair of light-sensitive cells to drive a motor 122 and to impart the necessary correcting rotation to the frame-aerial shaft 12 through gearing 125, 104, 141, and a differential motion 18, 21, 22. A mirror 119, Fig. 9, is mounted on the shaft of the compass needle 107, and reflects the light from a lamp 113 on to one or other of a pair of photo-electric cells 120, 120a, according to the direction in which the craft may yaw. This in turn energizes one or other of a pair of coils 128, 130, Fig. 12, wound around an armature 139 co-operating with a magnet 140, and so closes the appropriate contact 134 137, to pass current from a battery 127 through the upper or lower halves 133b, 133a of the field winding of the correcting motor 122, 132. The driving connection between the frame aerial and the pointer arms may be through ratchet gearing, Figs. 13 and 14 (not shown), or by servomotor mechanism, Fig. 4 (not shown). A modified arrangement for correcting for the effects of any turning movements by light-control is also described.

Title: Purification of phosphoric acid
IPC: C01B25/46
Filed: 1964-02-20
Abstract: Phosphonic acid is purified by extraction with a water-insoluble secondary or tertiary amine or salt or quaternary ammonium base or salt or mixtures thereof, having at least two saturated or unsaturated branch or straight chain aliphatic radicals each containing 7-15 carbon atoms attached to N.  Other N-attached groups preferably have up to 18 carbon atoms, and may contain substituents such as OH, COOH, OCH3, halogen, NO2 and SO3.  Salts, if used, are of acids stronger than HgPO4, i.e. Ka above 8 x 10-3, e.g. HCl, H2SO4. The extractan may be used as a 1-80% solution in a water-insoluble organic solvent, with or without additives to increase its solubility e.g. monohydric aliphatic alcohols containing 6-20 carbon atoms Lists of suitable amines, solvents, and alcohol are given.  The HgPO4 may be obtained by treating phosphate rock with H2SO4, and may be of 1-90% concentration.  It is preferably contacted, batchwise or in continuous countercurrent, first with sufficient free amine to remove only anionic impurities, e.g. F1,SO411, and then with amine salt to extract HgPO4 from cationic impurities, e.g. Fe, or with further free amine if the latter have first been removed.  The extractant may be regenerated by vaporizing the diluent, if used, and removing the extracted material with water, acid or base. Alternatively, NHg may be bubbled through the extractant phase to precipitate ammonia phosphates.  Organic impurities may be removed by filtration before and after extraction, and the acid may subsequently be concentrated e.g. by evaporation.
