Patent FI-953749-A (FI)
Inventor: KATISKO KEIJO
IPC: H04B1/40
Filed: 1995-08-07
Abstract: PCT No. PCT/FI96/00431 Sec. 371 Date Apr. 4, 1997 Sec. 102(e) Date Apr. 4, 1997 PCT Filed Aug. 6, 1996 PCT Pub. No. WO97/06607 PCT Pub. Date Feb. 20, 1997Amplitude and phase errors between branches I and Q of a transceiver utilizing phase quadrature modulation are corrected by preventing propagation of a nominal-frequency signal from a digital part through a loop part and a reception branch to an RSSI indicator by changing the frequency response of a component on the path of the signal. The same indicator that normally measures the payload signal, here measures only undesired signal components. After this, such amplitude and/or phase correction signals are determined with which the measuring result obtained from the indicator reaches the minimum. The resultant correction signals are stored in the memory, and the frequency response of the system is then restored to normal.
Patent FI-953991-A (FI)
Inventor: EGBERS JOCHEN
IPC: H03L7/07
Filed: 1995-08-24
Abstract: The method involves using a relatively inaccurate working frequency generator (FWORK) whose output is converted by frequency synthesiser (FSYN) to a more accurate frequency. An external reference signal (FE) is input to an operational frequency estimation circuit (FB) which frequency-normalises the signal before outputting it to a digital phase locked loop (DPLL). The DPLL output frequency (SIP) is synchronised with (FNOR), and is fed to an analogue phase locked loop (APLL), whose output is divided by a frequency divider (FT) which is included in its feedback loop to provide the final output (FA).

Title: Improvements in or relating to the manufacture of fertilizers
IPC: C05C3/00
Filed: 1925-01-14
Abstract: The process described in the parent Specification for obtaining sodium bicarbonate and a fertilizer containing potassium chloride and ammonium chloride by using sylvinite instead of sodium chloride in the ammonia-soda process, is modified by using a mineral, such as carnallite, kainite or schoenite, containing also magnesium salts instead of sylvinite.  After the precipitation of the bi-carbonate of soda, sufficient of the mineral is added to the warm mother-liquor to replace the sodium removed as bi-carbonate and the mixture is treated with ammonia and carbon dioxide in the requisite proportions to precipitate the magnesium as ammonium magnesium carbonate.  The temperature of the mixture is raised to 50 DEG  to 55 DEG  C.  The double carbonate may be separated, or recovered with the mixture of potassium chloride, potassium sulphate, ammonium chloride and ammonium sulphate which settles on cooling.  Both the double carbonate, and the mixture of potassium and ammonium salts, with or withut the double carbonate, may be used as fertilizers.  When the mineral used is poor in sodium, the mineral may be added in portions, the fertilizing matters being separated between the several additions. Specification 224,505 is referred to.ALSO:The process described in the parent Specification for obtaining sodium bi-carbonate and a fertilizer containing potassium chloride and ammonium chloride by using sylvinite instead of sodium chloride in the ammonia-soda process, is modified by using a mineral, such as carnallite, kainite or schoenite, containing also magnesium salts, instead of sylvinite.

Filed: 1950-01-18
Abstract: 681,824. Electric measuring systems. PYRENE CO., Ltd. Jan. 18, 1951 [Jan. 18, 1950], No. 1351/50. Class 40 (i). A device for determining rate of change of acceleration comprises a mechanically unbalanced moving coil milliammeter movement in which the unbalance is effected e.g. by an additional weight 20 or by displacing the balance weights 18. If the device is accelerated e.g. in the direction of arrow 22 the coil will assume a position dependent on the acceleration, the inertia of the moving system and the strength of the return spring 10. Fluctuations in the acceleration will cause the angular position of the coil to vary and an e.m.f. will be generated proportional to rate of change of acceleration which may be measured by a galvanometer if necessary, after amplification, or be used to actuate an indicator when the rate exceeds a predetermined value. Two arrangements for calibrating the device are described Figs. 2, 3 (not shown). Specification 681,847, [Group XXXVII], is referred to.

Title: Improvements relating to the manufacture of confectionery
IPC: A23G3/02
Filed: 1947-06-05
Abstract: 646,503. Endless-belt conveyers. SCOTT, A. T., and MARS, Ltd. June 5, 1947, No. 14936. [Class 78 (i)] [Also in Groups V and XL (b)] A band conveyer 20 delivers a slab of confectionary to another band conveyer 21 on which the slab is cut longitudinally into sixteen strips by rotary knives 52. Conveyer 21 runs around rollers 23 ... 27. Eight alternate strips are led away upwardly by eight V-belts 56A (one conveyer for each strip) and the remaining eight are taken downwardly by eight V-belt conveyers 56B. The conveyers 56A and 56B rim around rollers 57, 73 and 76 and fan outwardly, as shown in Fig. 6. At its terminal roller 73, 76, each belt 56A, 56B transfers its strip to two other V-belts 84A which support the strip at its edges. The belts 84A run around rollers 73, 85, and 76, 87. The strips pass under cutters 110, 111, which cut them transversely into bars, and during cutting they are supported by V-belts 84C which support the strips at their centre portions. The belts 84C run over belts 128 ... 131. The cut bars are transferred from belts 84A to V-belts 90A, 90B, which converge to a common plane and deposit the bars on a belt conveyer. Belts 90A and 90B run around rollers 85, 87, 91. As the slab passes from conveyer 20 to conveyer 21 it may deviate from a central position. To correct this deviation the conveyer 21 is automatically slewed in a horizontal plane about a vertical axis, the frame 32 which carries it being for this purpose pivoted in a footstep bearing 28. Two fixed lanterns 47 project light beams through the space between the two conveyers on to photo-electric cells 46. If the slab meanders off centre, one of the beams is interrupted by a border of the slab, whereupon the cells operate through amplifiers and relays to start a motor 48 which, through a screw-and-nut connection 49, 50 slews the frame 32.

Title: Improvements relating to ram air turbine driven auxiliary power generators
Inventor: MOSS NORMAN
IPC: F01D15/10
Filed: 1956-01-17
Abstract: 829,100. Ram air turbines. PLESSEY CO. Ltd. April 17, 1957 [Jan. 17, 1956], No. 1526/56. Class 110 (3). [Also in Group XXXIII] A generator of auxiliary power for an aircraft is arranged to be driven through gearing alternatively by a ram air turbine and a self-contained emergency power unit. A ram air turbine 1 drives through a hollow shaft 5 a member 8 attached to the planet gears 11 of an epicyclic gear formed by the sunwheel 9, a ring gear 10 and planet gears 11. The ring gear 10 is locked by freewheel mechanism 12 against rotation in the direction in which the turbine wheel 1 rotates so that the turbine drives the output shaft 7 connected to a generator unit 13 which must be driven by a prime mover to produce output and which may be, for example, an electrical generator, an hydraulic pump, a compressor, or any other source of servo-power for the aircraft. When the speed of the aircraft is insufficient to supply the required power, a supplementary turbine 14 is put into service. This turbine is preferably a gas turbine and is driven by the combustion of a monofuel such as isopropyl nitrate. The turbine 14 drives the shaft 7 through an epicyclic gear formed by the sun-wheel 15, planet-wheels 18, and outer ring gear 16. The ring gear 16 is prevented from rotating in the direction of rotation of the shaft 6 by the freewheel mechanism 17. During flight at high speeds, the member 19 can freely rotate so that no power is used to drive the turbine 14. At low air speeds, the ring gear 10 freely rotates so that no power is used to drive the turbine 1. In a modification, the member 19 drives the ring gear 10, the freewheel mechanisms 12 and 17 are omitted, the ring gear 16 fixed in the housing 3 and freewheel mechanisms are provided to prevent reverse rotations of the shafts 5, 6. In this case, the amount of power required from the turbine 14 is reduced at those speeds where the power of the turbine 1 is only slightly less than the power required for driving the generator 13.

Title: Improvements in and relating to rotary grates, particularly applicable to the furnaces of steam generators or the like
IPC: F23H9/02
Filed: 1936-01-20
Abstract: 462,075. Rotary grates. SCHMIDT'SCHE HEISSDAMPF-GES. Jan. 20, 1936, Nos. 1835 and 1836. Convention dates, Jan. 19, 1935 and April 16, 1935. [Class 51 (i)] A rotary grate comprising at least two superposed discs rotatable about different axes is fed with fuel near the centre or periphery of the upper disc and the fuel moves outwardly or inwardly over the disc in a spiral path on its way to the lower disc or discs. Figs. 1 and 2 show diagrammatically two methods of causing the fuel to follow a spiral path on the upper rotary grate disc. According to Fig. 1, the fuel is fed by a vertical shoot 2 at the centre of the grate disc 1 and during rotation of the disc the fuel is piled up against a wall 3 to form an obstruction which deflects the oncoming fuel outwardly at d and subsequently at e, the fuel being finally discharged at f. Fig. 2 shows a modification wherein the shoot 2 is arranged eccentrically to the grate disc 1 and the fuel itself forms a barrier which deflects the oncoming fuel and causes it to move in a spiral path. Fig. 3 shows a furnace grate in which an upper grate disc 1 rotates about an axis a, and a lower annular grate 4 rotates about an axis m. The axis of the fuel shaft 5 is at n and is angularly displaced in a direction opposite to the direction of rotation of the grate discs with respect to the line joining the axes a, m. The upper disc consists of grate bars 19, 21 and is driven by gearing from a shaft 29 and the lower disc consisting of bars 7 supported on rings 41, 4<11> is driven by gearing from a shaft 17. The outer edge of the upper disc is provided with teeth 31. The fuel residues are discharged from the lower disc through a shoot q which may be provided with a hinged flap at its inlet. The lower end of the fuel shaft is provided with an adjustable slide 35. Fig. 7 shows diagrammatically the spiral path of the fuel on the upper grate 1 when it is fed through a feed shaft 2 arranged at the periphery of the grate where is also arranged a barrier wall 3. The axis a of the grate may coincide with the axis of the firebox as shown or may be eccentric thereto in which case the wall of the firebox may be extended downwardly to the grate and form a deflecting barrier. Fig. 9 shows two superposed rotatable grate discs 1, 4 to which fuel is fed from the shaft 2, the axes of the grate discs being out of alignment with each other and with the central vertical axis of the firebox. The grate discs are rotated in the same direction by shafts 54, 55 end gearing 52, 53. A further modification comprises three superposed annular discs, the upper and lower discs being driven directly while the intermediate disc is connected by a link to the upper disc. With a number of grate discs, alternate discs may rotate about a common axis and the remaining discs about another axis. Various driving means for the grate discs may be employed.
