Abstract: 313,937. Magnus, H. March 23, 1927, [Convention date]. Addition to 287,525. Hydrocarbons, distilling and cracking.-In the process of continuous distillation and cracking of mineral oils and tar described in the parent Specification the process is carried out using heated reaction vessel in which the surfaces from which heat is emitted are arranged to be larger than those on which heat is absorbed by constructing such surfaces with corrugations, ribs, fins' &c. In the apparatus shown in Fig. 1 raw material enters at 2 and is passed by a pump 3 through heat exchangers 4<a> - - 4<e> to a pipe 5 leading to a distributing ring 6 in a distillation vessel 1 where it is blown tangentially, together with carrier gases, from nozzles 7 through molten metal 8 heated by a burner 9. The vapours pass to a condenser 13, driving a turbine 12 on the way, the non-condensable gases returning to the reaction vessel 1 with carrier gases introduced through a pipe 19 and entering the molten metal by a further set of nozzles. Unvolatilized liquid 20 passes through a pipe 21 and a power engine 22 which absorbs its energy to volatilizers 23, 25 and condensers' 26<c> - - 26<a>. Residues' and condensates pass through Pipes 27<a> - - 27e to heat exchangers 4<a> - - 4<e> and may be drawn off or selectively introduced by a pipe 30 into a cracking vessel 35 from which the vapours and liquid fractions are dealt with in the same way as in the first part of the apparatus, residues and condensates passing by a pipe 55 into the first part of the apparatus. The reaction vessel 1, Fig. 2, is provided with ribs 10, a metal liner 84 contacting the tops of the ridges. The reaction vessel 35 contains a number of tubes 59, Fig. 7, through which the heated gases or electrically heated coils pass and have ribs 64 on the outside. The volatilizer 25, Fig. 14 operates under vacuum, the liquid falling on' a corrugated surface 80 heated by hot vapours the flow of which may be controlled by an obturator 81. The furnace containing the two reaction vessels 1, 35 may have electrical contact devices 69 which on the escape of molten metal operate an alarm to stop the fuel supply or the supply of raw material for the distillation process, or tip the two reaction vessels, or apply vacuum to the reaction vessels to prevent escape of contents, or drive through the furnaces cooling air or gases or fluids preventing combustion such as carbonic acid, steam, foam, &c.

Patent GB-1600699-A (GB)
Title: Electronically controlled hydraulic drive system
IPC: F16H61/46
Filed: 1978-03-01
Abstract: Hydraulically driven vehicles with hydraulic wheel motors hitherto exhibited poor regulation of speed control over rough terrain. In addition, erratic loads on the prime mover (I.C. engine) resultant from varying loads on the wheel motors often causes engine stall. In the present system the I.C. engine (1) drives a hydraulic transmission pump (2) with variable displacement controlled by a swash plate (4). Encoding means (5) gives a first signal representative (A) of the engine throttle control setting. Engine speed sensor means (6) generate a second signal (B) representative of engine speed. Computing means (10) derives electronically from the first and second signals a third signal (F) applied to control motor means (19) which displaces the swash plate (4) to a position in which the load placed by the hydraulic transmission pump (2) on the engine (1) enables the engine (1) to maintain an engine speed directly related to the setting of the throttle control means.

Title: Measuring apparatus
IPC: G01R19/00
Filed: 1957-03-11
Abstract: 824,983. Voltage measurement; measuring bridges. FOXBORO CO. March 11, 1957 [March 12, 1956], No. 8020/57. Class 37. Apparatus for measuring the changes in potential of a high-impedance voltage source 10 and adapted to produce corresponding changes in output power of substantial magnitude without drawing any effective power from the voltage source comprises: a variable capacitor coupled across the voltage source, the capacitor plates 28, 30 being relatively moved by the resulting electrostatic forces to vary the capacitance between the plates; and a capacity responsive network 44 coupled across the plates to sense such capacitance variation. As described, a D.C. voltage source 10 is connected through isolating resistor 18 to electrostatic voltmeter 22 the capacitor plates 28, 30 of which are connected through D.C. blocking capacitor 40 across terminal points 42, 46 of a balancing impedance bridge 44 energized by a 5000 c.p.s. signal from oscillator 58 applied across terminals 42, 52 of the bridge. Variation in the source potential causes capacitance changes between plates 28, 30, thereby unbalancing the bridge circuit; the magnitude and phase sense of the unbalance currents depending respectively upon the magnitude and sense of the source potential variation. The bridge output across terminals 46, 68 is amplified by an A.C. amplifier 76 and then fed to phase-sensitive detector 86 provided with a phase-reference signal from the oscillator 58; the output of detector 86 being a D.C. signal the magnitude and polarity of which correspond respectively to the magnitude and phase sense of the unbalance currents. This output from detector 86, after amplification at 100, is used to drive a solenoid motor 102, the cylindrical core 112 of which moves in a direction dependent on the output polarity from detector 86. The core actuates a linkage 114 connected to the movable pen 116 of a recorder 118, and to the variable capacitor 66 of the bridge which is thereby rebalanced. The linkage may also be connected to a controller adapted to maintain the source potential 10 at a constant value. For measuring a source of A.C. potential, an inductor in parallel with blocking capacitor 40 provides a rejection filter for the frequency, e.g. 60 c.p.s., of the A.C. source; the oscillator 58 may provide an R.F. signal in this case to simplify the filtering. Alternatively, when measuring a high-frequency A.C. voltage, the oscillator 58 may have a low-frequency output. Specifications 647,025 and 773,032, [Group XXXV], are referred to.
