Patent GB-131899-A (GB)
IPC: F02P1/00
Abstract: 131,899. Splitdorf Electrical Co., (Assignees of Martin, J. S.). Jan. 16, 1915, [Convention date]. Magnetos, driving.-In devices for imparting accelerated movements to the rotors of ignition magnetos of internal-combustion engines at starting, the driven and driving members are normally 'locked together but unlock automatically during the initial movement for energizing the accelerating-spring, and the device is automatically put out of action when the spark is advanced after starting. The driven member secured to the rotor shaft 9 comprises a disk 10 provided with an arcuate groove 11 to accommodate the accelerating- spring 16, and the driving-member comprises a disk 13 provided with lugs 27 by which it is driven from the engine, and with a lug 15 which projects into the groove 11 to energize the spring 16. The disks 10, 13 are normally locked together by bolts 19 adapted to slide in the disk 10 and to engage in apertures 21 in the disk 13. Lugs 20 on the bolts engage in cam-slots 23 in a ring 22 loosely mounted on the disk 10. When the engine is turned, the ring 22 is arrested by a stop 29 on it engaging a pivoted catch 28, and the disk 10 continues to move until the slots 23 disengage the bolts 19 from the disk 13; the disk 13 continues to turn and compresses the spring 16 until a cam 38 on the disk disengages the catch 28 and frees the disk 10, which is then accelerated until it overtakes the disk 13. The ring 22 is restored to its normal position on the disk 10 by means of a spring 26, the bolts 19 thereby being re-engaged with the apertures 21 to lock the disks together. When the usual spark-timing device is turned to advance the spark after starting, link and lever connexions 36, 35, 32 rock the catch 28 out of the path of the stops 29 to render the trip mechanism inoperative. This can also be effected independently by a rod 41.
Patent GB-391613-A (GB)
Title: Electrical speed regulator
IPC: H02P7/06
Filed: 1932-05-07
Abstract: 391,613. Automatic regulation. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET, Võsteras, Sweden. May 7, 1932, No. 13213. Convention date, May 9,1931. [Class 38 (iv).] A motor 2 supplied by a Ward- Leonard generator 1 is maintained at a constant slow speed by causing it to drive a cam disc 5 which imparts oscillations to pins 7 carrying contacts 9 and urged towards the disc by springs 8. Co-operating contacts 11 carried by pendulums 12 remain in engagement with the contacts 9 so long as the speed is below a critical value; above this value the inertia of the pendulums prevents them following the motion of the contacts 9 towards the cam, thus each pair of contacts 9, 11 is opened for a half of the oscillation. As the cam is constructed so that the oscillatfons of the contacts 9 are out of phase with each other, and as all the contacts 9, 11 are in a series circuit, this circuit is opened above the critical speed and inserts a resistance 4 in the generator field circuit. For high-speed operation without speed control, the resistance 4 is short-circuited by a. relay 14. A modification consists in having the springs 8 of such a strength that rupture of contact between pins 7 and the disc 5 occurs at the critical speed. The Specification as open to inspection under Sect. 91 comprises also another modification in which the motor generates an alternating current which maintains the contact member in oscillation. This subject-matter does not appear in the Specification as accepted.

Filed: 1933-05-08
Abstract: 419,002. Indicating-apparatus; adjusting wireless apparatus. SPERRY GYROSCOPE CO., Ltd., Great West Road, Brentford, Middlesex, and HARDING, W. G., 28, Allan Way, North Acton, London. May 8, 1933, No. 13338. [Class 106 (iv).] Means for indicating angular motion comprise two adjacent members rotated at all times through distances proportional to the motion to be indicated but different from each other, one of the members serving as a mask in relation to the other so as, upon relative movement between the members, to uncover indications on the said other member. The invention is shown applied to a compass repeater. One member forms a card 7, graduated as shown in Fig. 5, and is moved through five times the angle moved by the main compass by a motor 2 and gearing 3, 4, 5, 6. The card 7 is pivoted at 13 and a mask 8 comprising the other member is pivoted at 14, the mask having seven gaps 18 and being connected to the card by internal gearing 12, 11 having a ratio 35: 36. This arrangement provides such relative motion between the card and mask as to expose successively the appropriate figures on the card 7 during the five complete rotations of the latter corresponding to one rotation of the main compass card.

Title: Process for the preparation of fertilizer salts from solutions obtained by the decomposition of phosphate rock
IPC: C05C1/00
Filed: 1964-04-01
Abstract: An aqueous solution of K, Mg, or NH4 phosphate and/or nitrate, obtained by decomposing phosphate rock with excess concentrated HNO3 followed by addition of the corresponding sulphate, and removal of gypsum, is treated with a water immiscible aliphatic alcohol having 4-6 C-atoms, e.g. butanol, to extract free acid. At least 1 part, preferably 2.5-3.5, of alcohol to 1 part of solution (by volume) may be used. The conversion of nitrate and H5PO4 into phosphate and HNO3 during extraction may be counteracted or promoted respectively by adding to the alcohol HNO3 or 1 part of a lower aliphatic ketone, e.g. methyl isobutyl ketone, per 2 parts alcohol.  The process may be carried out in stirring vessels or continuously in packed or plate columns.  Phosphate rock is decomposed with at least 40%, e.g. 55%, acid at below 40 DEG  C., and the liquor fed into vessel 2 together with sulphate solution from 3. Gypsum is filtered and removed at 6; part of the mother liquor is used to dissolve sulphates in 3, and the remainder is fed to the top of extraction column 9, alcohol being fed in at the base from 10.  The aqueous solution discharged from the base is stripped of alcohol at 13, treated at 14 with gaseous NH3 to neutralize any free acid, evaporated at 16, and granulated. Alcohol from the top of 9 is washed at 18, water being fed back to the top of 9, then neutralized with gaseous NH3 in 22.  The ammonium salts solution is separated in 24 from alcohol, which is returned to 10, then stripped at 27, evaporated at 28, and granulated with 100% water-soluble phosphate.  Mixtures of KNO3, KH2PO4 and NH4H2PO4, and of KNO34NH4NO3 may be obtained at 16.
