Title: Improvements in or relating to engine governors
IPC: G05D13/00
Filed: 1927-04-08
Abstract: 281,155. Uskside Engineering Co., Ltd., and Wood, J. W. April 8, 1927. Fluid governors.-A governor for regulating the supply of pressure fluid to engines e.g. compressed air engines for operating jigger conveyors, comprise a casing 1 the inlet 3 and outlet 4 being coupled to the compressed fluid circuit a passage being provided through a circular port 11 opened and closed as required by a piston 11 balanced between tluid pressure on the head 17 and spring pressure on the hollow piston 8, a bye pass 16 being provided from the engine side to the piston head 17. The spring compression is set by a screw 12. Maximum throttling is set by the adjusting screw 18. In operation, when the engine is overloaded, pressure accumulates at the outlet 4 and travels through the passage 16 to the piston head 7 to press it back and increase the port opening 11 thus allowing more working fluid to pass from 3 to 4. When the engine tends to speed up, the pressure in passage 16 diminishes and allows the spring 9 to push the piston 8 to the right to diminish the port opening 11. The piston 8 has a spring ring 20.

Title: Ammonium salts and fertilisers based thereon
Inventor: DEE GEOFFREY THOMAS
IPC: C05B7/00
Filed: 1962-03-15
Abstract: <PICT:1042132/C1/1> The invention comprises a process for making ammonium nitrate or mixtures of ammonium salts containing ammonium nitrate wherein in a first stage a liquid mixture containing ammonium nitrate and nitric acid is formed or an acid mixture containing ammonium nitrate and at least one of ammonium sulphate and ammonium phosphate is formed in the liquid phase, and wherein in a second stage the product from the first stage is treated in the liquid phase at an elevated temperature with a countercurrent stream of ammonia gas, the second stage being operated so that the water vapour evaporated as a result of treating the product from the first stage with ammonia gas is removed out of contact with the mixture being treated with ammonia in the second stage at a point where the pH of the liquid phase is the same as that of the product from the first stage, and if any water vapour is separated in the first stage this is done at a similar pH to that at which water vapour is separated in the second stage.  When making ammonium nitrate the pH is preferably in the range of 3.5 to 4.5, and when making mixtures of ammonium salts a pH of 2.0 to 3.0 is preferably used.  In the second stage a suitable gas inert to the reaction mixture may be fed along with the countercurrent stream of ammonia.  Part of the final product may be returned to the first stage. Example 1 refers to the flow sheet shown in Fig. 1, in which a phosphoric-acid-containing mix is fed from tank 1 through preheater 2 to reactor 3.  Ammonia is also fed to reactor 3 through line 5.  Water vapour from the boiling partly ammoniated product from reactor 3 is condensed in condenser 10.  The ammoniated product is led to the head of reactor 6 while a mixture of ammonia and air is fed to the base of reactor 6 through lines 7 and 8 respectively. Further ammoniation takes place and the resulting product is recovered through line 9. Water vapour and any unreacted ammonia is condensed in condenser 10.

Patent HU-T52898-A (HU)
Title: Change-over filter
Inventor: BLIND MANFRED
IPC: H03H7/46
Filed: 1989-03-08
Abstract: In known diplexers for separating a total frequency range into at least two part-frequency ranges or connecting these together, via which a remote power feeding current is fed into the connecting point of a branch, constructed, for example, as high-pass filter, for a higher part-frequency range for supplying an active component with operating current, this branch exhibiting at least one series capacitor and a shunt inductance connected to its connecting point, the high-pass filter is bypassed by a choke (D) for the transmission of the remote power feeding current (Figure 1). Due to the inter-turn and stray capacitance of this choke (D), the transfer characteristics of the diplexer are greatly impaired at high frequencies and/or feed currents. To avoid or at least to minimise this disadvantageous effect, it is proposed that the shunt inductance (L7) connected at the connecting point (A2) of the branch (4) for a higher frequency range (first satellite intermediate frequency range) is connected to earth via a bypass capacitor (C7) and the junction point (P1) of these two reactances (L7, C7) is connected via a choke (Dr1, Dr2) to a circuit point (P2) of a branch (3) for a lower part-frequency range (40 to 860 MHz), which is connected via at least one inductance (L1, L2, L4) to the separating point (A) or junction point of the diplexer (1). <IMAGE>
