Title: Improvements in the production of fertilisers from phosphate rock and the like
IPC: C05B7/00
Filed: 1930-04-08
Abstract: Solutions containing ammonium phosphate and nitrate are treated to precipitate an insoluble phosphate, and the latter after separation from the remaining ammonium nitrate solution is reconverted to ammonium phosphate by treatment with ammonia. Ferric nitrate may be used as precipitant, the solution preferably be maintained faintly alkaline during precipitation, and the ferric hydroxide obtained on reforming ammonium phosphate be reconverted to nitrate for re-use; or it may be used as such in the precipitation step.  When the mixture of phosphate and nitrate has been obtained from phosphate rock by treatment with nitric acid in conjunction with ammonium sulphate followed by neutralization of the solution with ammonia the ammonium phosphate recovered from the iron &c. phosphate may be added during the neutralizing step.  In such case the major portion of the ammonium phosphate may be recovered directly from solution by crystallization.  Specificatio 343,701 is referred to.

Title: Composite television signal blanking apparatus
Inventor: BAUN LEONARD JOSEPH
IPC: H04N5/08
Filed: 1968-03-07
Abstract: 1,216,394. Television. R.C.A. CORPORATION. 7 March, 1968 [30 March, 1967], No. 11252/68. Heading H4F. In a circuit for removing synchronizing pulses 14 from a composite television signal 11, e.g. when it is necessary to regenerate and replace distorted sync. pulses, the received signal is supplied via terminal 12 and diodes 17, 18, which conduct during the video signal interval, to the output terminal 19. During the blanking pulse interval a negative-going pulse 25 is applied to the bases of normally non-conducting transistors 23, 24 so that they saturate, the time constants being arranged to make transistor 24 operate slightly before transistor 23. This renders diodes 17, 18 non-conducting and the output signal 11a is blanked at the black level 15 to remove the sync. pulse. In order to reduce switching transients the transistors 23, 24 are biased so that they do not conduct until the switch pulse 25 reaches a level 27 approaching its maximum level and also become non- conducting when pulse 25 falls to level 27.

IPC: B63B3/06
Filed: 1917-08-13
Abstract: 120,745. Ritchie, H. C., and Kahn, M. Aug. 13, 1917. Concrete vessels and pontoons.- Reinforcedconcrete ships, floating docks, pontoons, &c. are built up of pre-cast and matured unit sections, each comprising a portion of the shell, preferably with flanges at either side, the units being assembled with the flanges abutting to form one set of frame members, preferably the transverse frames, the other set of intersecting frame members being then cast in situ so as to be integral with the assembled units both as regards concrete and the steel reinforcement bars. Fig. 1 shows assembled side units A with the flanges a<2> joined to form transverse trame members. The units A abut at the bottom against bilge units F, Fig. 3, and a longitudinal stringer C is moulded along the joint on bars c' which pass through holes a', a<10>, f<6>, f<10> in the transverse frame members a<2> and are united by stirrups and links c<2>, c<3>. Longitudinal or diagonallyarranged framing-bars a<7>, a<8> pass through other holes a<6> in the flanges a<2> of the units, and are anchored at the ends, for example, in the side stringer C and in the sheer-strake member B. The reinforcements a<5> of the transverse frame flanges a<2> are anchored to the longitudinal reinforcements of the frame members which are cast in situ, for example, to the bars b<1> of the sheer strake B, as shown, and to the bars c<1> of the side stringer by curving round the bottom holes a<6>, a<10>. Additional outer holes a<10> are provided to take additional bracing members or bars, as a<11>, as are required for strength, and such bars may be used to form intermediate side stringers cast in situ. In building up the bottom of the ship, the ends of the bottom units E terminate at one end in the centre keel G and at the other end in the bilge keel H, both cast in situ after the reinforcement of the bilge and floor units have been anchored to those of the keels. The deck beams are pre-cast in units D and terminate in the sheer strake B and the hatch coamings P which are both cast in situ. The deck d<2> and inner ship's bottom M also are cast in situ on expanded-metal sheeting. The transverse bulkheads may be constructed either in situ or precast in unit sections. The stern post may be of cast or forged steel with anchoring pieces to embed in the concrete hull. The ship may also have longitudinal under-deck beams integral with the hatch coamings with columns underneath between the several decks and in the hold, all cast in situ. Watertight joints between the abutting flanges are obtained by running waterproofed cement between them and by recessing the edges thereof and keying the recess with bitumen &c. This system of construction facilitates repairs as damaged units may be removed and replaced.
