Abstract: 592,249. Torque and phase displacement control. SMITH & SONS (ENGLAND), Ltd., S., MEREDITH, F. W., FURZEHILL LABORATORIES, Ltd., and MILSOM, F. R. March 20, 1945, Nos. 7064/45 and 4710/46. [Class 38 (iv)] An automatic control system for aircraft or watercraft comprises a servomotor which is supplied from one of two circuits depending upon the direction of rotation required, and an instrument which is fed in opposition by these circuits for indicating any unbalance caused by the torque reaction due to out-of-trim conditions. To effect rotation of a three-phase hysteresis motor, e.g. of the kind described in Specification 576,248, in one direction, current flows through a resistance 6, forming one ratio arm of a Wheatstone bridge 7, under control of a saturable inductance 8 and to effect rotation in the opposite direction current flows through a resistance 9, forming another ratio arm of the bridge, and a saturable inductance 10. When a craft is properly trimmed, the resistances 6, 9 are heated equally and the bridge is balanced. Out-of-trim conditions produce an increase of current in one of the resistances 6, 9, the bridge is thus unbalanced, and a galvanometer 12 indicates the presence of out-of-trim conditions. In a modification, Fig. 2 (not shown), the Wheatstone bridge is arranged between the controlling inductances and one of the phases of a two-phase hysteresis motor, the other phase of which is excited in quadrature by the supply. In another modification, Fig. 3 (not shown), the resistances 6, 9 are replaced by heating coils. Within each heating coil is arranged a thermocouple, the outputs of which are connected, in opposition, to the instrument 12. A relay controlling a motor for operating trimming tabs may be substituted for the galvanometer. Specification 576,249 also is referred to.

Title: Control system for controlling operations in internal combustion  engines
IPC: F02D41/30
Filed: 1971-12-22
Abstract: 1372260 Engine control systems; reading records photo-electrically VOLKSWAGENWERK AG 22 Dec 1971 [24 Dec 1970] 59603/71 Headings G1A and G1N In an I.C. engine control system, engine operations are controlled using a disc and a transmitter which are moved relatively to each other by at least two engine operating parameters, the disc being divided into elements having a common property which varies from element to element thereby storing information regarding the operations to be controlled Figs. 1 and 2 (not shown). Alternatively, a plurality of discs mounted for  coaxial movement are provided, one for each operation, Fig. 3 (not shown). In one form the transmitter includes a light source and photo-cell, the elements of the disc then having varying opacity. Alternatively, the transmitter may include a magnetic circuit, the disc then having areas of different thickness to vary an air-gap in the circuit. As shown in Fig. 4, the disc is provided with areas I to VII having different opacities, each area corresponding to a stored control of an engine operation. The angular position of the disc about a point 50 is for example determined by engine speed, and the radial position, relative to the disc, of the transmitter (not shown), is determined by induction pressure, or throttle position. Other parameters which could be used include air throughput, sub-atmospheric pressure in the region of the carburetter, or pressure in the exhaust. The output of the transmitter is applied to a receiver, Fig. 5 (not shown), which includes a separate discriminator for each operation to be controlled. Operations to be controlled include detoxication of exhaust gases, pre-heating of induction air, cooling of engine, exhaust gas recirculation, air and/or fuel metering of a carburetter engine, ignition advance and retard, and switching of vehicle lights in dependence upon engine speed, as well as fuel injection control.

Title: Blanking circuits
IPC: H03K19/0185
Filed: 1972-12-29
Abstract: 1419271 Displays; zero - suppression HITACHI Ltd 29 Dec 1972 [29 Dec 1971] 60030/72 Heading G4H [Also in Divisions H1 and H3] A blanking circuit producing a two level output O comprises: a series arrangement of a number of transistors T1, T2 and a load T3; a blanking input BL connected to an input of one of the transistors T2 and to the input of an inverter IN; a signal input I connected to the input of the transistor T1; and an output control circuit including a semi-conductor element T4 which may be either in a first state in which it does not affect the output O or in a second state in which it determines one of the output levels. The semiconductor element T4 is formed with a thick layer insulating the gate so that, in its first state, it does not function as a transistor with normal gate voltages. For the second state, the layer is further etched away until the element can function as a transistor. When BL is in its low level condition (negative potential) the gate is enabled and the signal I is passed to the output with polarity inversion. When BL is in its high level condition (earth potential), the gate is blocked and the level at O depends on the state of the element T4. In the case when element T4 is not functioning as a transistor, the level at O is low when BL is high. When element T4 is functioning as a transistor a high signal at BL renders T4 conducting clamping the output O to earth, giving a high level output. Opposite polarity outputs may be obtained at O by means of an inverter T5, T6. The circuit is employed in a digital display arrangement, a common blanking signal being applied to a number of such circuits each having a separate input (I 1  ... I m ) and a separate output (O 1  ... O m ), Fig. 6 (not shown). The display system, Fig. 1, of a portable calculator includes a register RG in which binary signals are circulated, a memory M in which the signals from the register are stored in parallel and a decoder DC which converts the signals into a form for lighting up or writing predetermined numerals on display devices Dp 1  ... Dp 8 . Digit changing signals Dt 1  ... Dt 8  for operating the display devices in time sharing are also provided. The blanking circuit BC is provided to obviate the flicker effect produced when adjacent digit changing signals overlap, and also to provide a zero masking signal which prevents the display of unnecessary "0" at higher digits when displaying numbers not involving all the available digits.
Patent GB-664375-A (GB)
IPC: C01B32/50
Filed: 1948-10-25
Abstract: <PICT:0664375/III/1> Ammonia and carbon dioxide are separated by selective absorption of the ammonia in an aqueous solution of an ammonium salt of a strong acid, e.g. ammonium nitrate, under a pressure higher than atmospheric, e.g. at 2 to 5 atm.  The ammonia liquor so obtained may be rectified under pressure to release the small proportion of carbon dioxide dissolved in it.  The process is particularly applicable to the recovery of unreacted ammonia and carbon dioxide from the effluent gases in the high-pressure synthesis of urea. The urea solution from the reaction-autoclave is expanded through valve 1 into container 2 which is maintained at a pressure of 3.5 atm.  The gaseous mixture set free in container 2 is passed to column 3 which is divided into an upper-ring packed section maintained at about 100 DEG C. by a water-jacket, and a lower plate-section heated at the base by coil 7.  The gaseous mixture enters the column between the two sections, and ammonium nitrate solution is introduced at the head.  Carbon dioxide leaves the head of the column, is cooled in heat-exchanger 5, and passes to a gas-holder through valve 6.  The solution of ammonia in aqueous ammonium nitrate is rectified in the lower-section of column 3; and the liquor from the base is passed through a coil in the base of column 9, and is then introduced into the head of regenerator column 8.  The regenerated ammonium nitrate solution withdrawn from the base of column 8 is pumped back to the head of column 3. The ammonia and water vapours from the head of column 8 are passed to column 9. Ammonia is withdrawn from the head of column 9 and is collected in a gas-holder.  The water obtained at the base of column 9 is supplied to the jacket around the upper section of column 3.
