Title: Production of complex nitrophosphate fertilisers
IPC: C05B11/06
Filed: 1969-01-29
Abstract: Nitrophosphate fertilizers are prepared by: (i) digesting a naturally occurring calcium phosphate with aqueous nitric acid in the presence of a gas containing one or more nitrogen oxides (ii) cooling the solution obtained in order to crystallize at least a part of the Ca(NO 3 ) 2 present as Ca(NO 3 ) 2 .4H 2 O (iii) separating the Ca(NO 3 ) 2 .4H 2 O (iv) neutralizing the mother liquor with ammonia, concentrating the resulting mixture, adding if desired a potassium salt and then granulating the mixture to form a nitrophosphate fertilizer (v) thermally decomposing the separated Ca(NO 3 ) 2 .4H 2 O in the presence of the off gases from step (i) and (vi) recycling the nitrogen oxide containing gas from step (v) to step (i). In the preferred embodiment, the phosphate and nitric acid (concentration less than 55%, preferably 35%) are added to reactor, 1, which is at 20-60 C. (30-40 C. preferred). Both the liquid and the off gas therefrom are passed to reactor 2, which is at 20-90 C. (40-60 C. preferred). The liquor is cooled to 12 C. at 3 and 4, and Ca(NO 3 ) 2 .4H 2 O is separated at 5. The liquor containing Ca(NO 3 ) 2 , HNO 3 , H 3 PO 4 , H 2 SiF 6 , and SiO 2 , goes on to be converted into a nitrophosphosphate by the addition of HNO 3 and NH 3 . The separated Ca(NO 3 ) 2 .4H 2 O is melted at 6, mixed with CaCO 3 from 10, and passed to the granulator drier 7, which is heated by the combustion gases of the decomposer 9. The screen 8, enables only particles of size 1-15 mm. to pass to the decomposer 9. Oversize particles are returned to the melter 6, and undersized particles are returned to the granulator 7. Off gas from reactor 2, now containing SiF 4 and HF, is mixed with CO 2 before entering decomposer 9 which is at 440-750 C. The CaCO 3 formed in the decomposer is returned to 6, via 10, excess being removed. This CaCO 3 also contains some CaF 2 , SiO 2 and Ca 3 (PO 4 ) 2 . The off gas from the decomposer 9, is passed to reactor I, either directly or by first condensing off part at 27 and adding as liquid to reactor 1. Alternatively the Ca(NO 3 ) 2 containing solution or molten Ca(NO 3 ) 2 may be passed directly from 5 to hot CaCO 3 in 9, or less preferably a solution of Ca(NO 3 ) 2 is sprayed on to a bed of lime, no CO 2 being added to the off gas from 2. The Ca(NO 3 ) 2 .4H 2 O may be removed by solvent extraction with, for example, isobutanol.

Title: Sensing circuit for use in vehicle braking systems
IPC: B60T8/172
Filed: 1969-05-21
Abstract: A sensing circuit for use in a vehicle braking system, comprising in combination a generator for producing an output signal having a magnitude dependent on the speed of rotation of a selected wheel of the vehicle, electromagnetic means 21 for controlling the braking effort applied to the wheel, and a control circuit coupling the generator to the electromagnetic means 21. The control circuit produces from the generator output a signal representing the deceleration of the selected wheel, and initiates current flow in the electromagnetic means 21 at a predetermined magnitude of deceleration and then increases the current flow with increasing deceleration so that the current flow is proportional to the deceleration. In the construction shown the control circuit is provided with a normally conductive input transistor Q1, the bias thereon being completely removed at the predetermined magnitude of deceleration the cutting off of transistor Q1 causing an output transistor 8 to conduct and activate the electromagnetic means 21. An amplifier is positioned between the two transistors Q1, Q8 and a feedback circuit is provided from the output transistor to stabilize the output current. The feedback is delayed momentarily to allow an increased current flow in the electromagnetic means. The circuit further comprises a second speed circuit 22 to provide another input to a transistor Q4. In a modification (Fig. 2, not shown) a current pump is initiated at a deceleration above a predetermined level so that the brakes are released completely.

Patent ES-384330-A1 (ES)
Title: Apparatus for deflashing annular palstic articles
IPC: B29C35/04
Filed: 1970-10-08
Abstract: Plastic workpieces, such as automobile steering wheels, are mounted on rotatable shafts on workpiece carriers spaced at intervals along an endless conveyor chain arranged a drive track, the shafts being inclined downward and outward therefrom and the lower course of the conveyor chain extending adjacent a tank containing a plastic solvent solution. As the workpieces are carried into the tank, they are lowered into the solution by the combination of shaft angle and track angle, whereupon pulleys on the shafts engage the drive track and are rotated thereby together with the workpieces carried thereby as they move through and along the tank while the workpieces are partly immersed in the solution, so as to agitate it as they rotate and pass through it. From the tank, the workpiece carriers and workpieces are carried upward through an oven which rapidly evaporates the excess solvent that has not already been drawn off by the combined actions of surface tension and gravity. The plastic workpieces emerge dry, polished and free of flash from the oven and pass around a conveyor chain drive sprocket to an unloading station, immediately beyond which is a loading station for the next plastic workpieces to be processed.

Patent ES-405277-A1 (ES)
Title: Vehicle seats
IPC: B60N2/70
Filed: 1972-07-28
Abstract: When vehicle seats are covered with a synthetic plastics material there are problems in hot weather because they do not soak up perspiration as would natural leather. On long journeys or on hot days, therefore, passengers clothes in contact with such seat coverings tend to become wet with perspiration. This is mitigated according to the invention by using the seat cushion as a pump which expells air as it is depressed by the movements caused by the person sitting on the seat or vehicle movements and the expelled air is forced out through the front face of the back rest of the seat. Air is also sucked in through the top face of the seat cushion at times when the seat cushion becomes less depressed. In this way a flow of air is provided between the passenger and the seat which removes perspiration.
