Title: Improved Means for Controlling Movement in Two Directions from a Distance.
Inventor: PROUMEN HENRI JACQUES GUILLAUM
IPC: F41G7/30
Filed: 1917-05-29
Abstract: 127,848. Proumen, H. J. G., and Lautreppe, A. Le C. de. May 29, 1917. Wireless control of distant apparatus.-Apparatus or mechanism, such as a rudder, is controlled from a distance in such a way that the emission of waves from a transmitting-aerial causes the mechanism to move in one direction, while, in the absence of such emission the mechanism moves in the other direction. The rudder a or other apparatus is moved in either direction through linkages d, e bv a piston c acted on by compressed air admitted to the cylinder by the movement of a valve q. This valve is actuated in opposite directions by magnets 5, 8 the windings of which are connected to contacts arranged on opposite sides of the armature 2 of a relay 10. The wireless receiving conductor is in the form of a spiral wire 12 mounted on an horizontal pivot and fitted with gyrostats 16 to maintain its angular position fixed. The transmitting-antenna is set perpendicular to the axis of the receiving-conductor. A coherer 11 in the receiver circuit is also included in a batterv circuit through the relay 10. When no waves are being received, the armature 2 is down, and the magnet 5 is energized by a battery 1, thus causing the rudder to be thrown over to one side. The rudder is reversed by sending waves which cause the relay 10 to be energized, and the armature 2 to be lifted, thus disconnecting the battery 1 from the magnet 5 and coupling it to the magnet 8. In a modification, the relay magnet 10 actuates the valve g directly against the action of a spring. Reference has been directed by the Comptroller to Specification 27128/98.

Filed: 1962-02-28
Abstract: 977,427. Data transfer apparatus. SPERRY RAND CORPORATION. Feb. 28,1962 [June 19,1961], No.7765/62. Heading G4A. A data transfer circuit is adapted to transfer with shift a data word from a first register to a second register,the amount of shift being determined by a number in a third register. As described,a binary number stored in an 8-stage input register 102 is transferred via a "shift matrix" circuit 100 to a 15-stage output register 104,the amount of shift being determined by a number in a register 106. The circuit 100 comprises "transformer-diode" circuits TD-0 to TD-10 containing two output windings and up to four input windings. The amount of shift is by up to seven bit positions, the amount-determining number being registered in a register 106 comprising six bi-stable stages divided into a first part 108 containing four stages representing decimal digits 0-3 respectively and a second part 110 containing two stages representing decimal digits 0,4 respectively, the arrangement being such that just one bi-stable stage in each part 108, 110, is set. In operation, an input register clock pulse 112 and a digit timing clock pulse 114 are effective to energize an input winding of appropriate transformers TD, determined by the register part 108, if the bit to be transferred is a "1",the register part 110 being effective to enable an output winding of one of the energized transformers to energize an appropriate input line 138 to the register ,104, into which the "1" bit is written on the occurrence of a clock pulse 116 at the required position as determined by the number in the register 106. If the bit to be transferred is a "O", none of the transformers TD to which the corresponding register stage is connected is energized.

Abstract: 1,047,415. Distillation columns, automatic control. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Feb. 23, 1965 [Feb. 25, 1964], No. 7803/65. Heading B1B. In a system for the continuous distillation of a mixture by means of a fractionating column 1 and a condenser 3 for the top product, the valve 13 controlling the discharge of the top product from the system through conduit 5 is adjusted by a signal from a controller 11 which compares the composition of the top product with a set value, and the return of reflux to the column through conduit 4 is controlled by a valve 12 which is automatically adjusted by a signal obtained by summing the output signal of controller 11 and the output signal from a controller 8 which compares the liquid-level in the accumulator 2 for the top product with a set value. For example, the output signal of the adding element 9 will open valve 12 further if the concentration of the desired component in the top product is too low, and also if the liquid-level in accumulator 2 is too high. The influence on the adjustment of the reflux flow of one of the signals, i.e. from controller 11 or controller 8, may be made stronger than that of the other.
