Abstract: 1,231,998. Photogrammetry. HOBROUGH Ltd. 27 Oct., 1969, No. 52540/69. Heading H4D.  In photogrammetric apparatus a pair of aerial stereo photographs are scanned by respective television cameras, one of the produced video outputs is fed to a cathode ray tube display forming part of a photographic print out system and, such that the printed out photograph shall be an orthophoto directly convertable to a map, the scanning patterns of the camersa are distorted from the basic rectangular raster until the two resulting video signals are substantially identical, the distortion being under the control of a computer fed with the outputs of a correlator receiving and comparing the two video signals. The signal controlling the raster distortions is fed to serial circulating memory means so as to be stored and usable for an extended period. The stereo photos 12A, 12B, Fig. 3, are moved on carriages 17, 18 so that television cameras 25, 26 scan small areas of each in approximately the same position. With a photograph 100 x 220 mm. and an 8 mm. square raster, 350 pairs of such scans have to be made to cover the whole photo. The video signals are fed on lines 50, 51 to correlator 49, which produces co-ordinate misregistration signals representing X parallex (line 52), Y parallex (line 53) and a signal indicating the equivalent height # Z  of the scanned terrain. On the basis of these signals a computer 29 produces signals altering the rectangular scan signals for generator 56 in raster shapers 62 and 63. The video signals made substantially equal as explained are fed to a stereo viewer 42 and also via a switch 54, to the print out display tube 59, switch 54 ensuring that, under the control of the computer, the video signals from camera 25 are used to print out the left hand half of the photograph and those from camera 26 for the right hand half. The correlator comprises, Fig. 5, x and y parallex discriminators 95, 92 receiving the video inputs and producing respective x and y parallex signals. These signals are averaged by means 105, 98. The y parallex signal is also fed to a signal analyser 97 together with the scanning signals, to produce y scale and x skew signals. The x parallex signal is also fed to an analyser 106 to produce the height # Z  signal. The analyser 106 contains the referred to circulating memory means and is shown in Fig. 6. The x parallex signal is thus fed to one input of an adder circuit 111 where it is added to the output of the adder circuit delayed at 113 by one frame period. The # Z  signal at the adder output is thus continuous and maintains the value necessary to keep the video signals equal. A second circulating circuit can be added in tandem with the first having a delay of one line. The raster shapers 62, 63 are shown in Fig. 4 wherein the computer 29 produces multiplying coefficients K 1 /K 6 . Standard x and y square raster waveforms from generator 56 are fed on lines 70 and 71. The shaper also receives the # z  signal; A series of multiplers 72, 73, 81, 84, 86, 87 and adders 78, 79 produce distorted scan waveforms X and Y wherein:

Abstract: 1,233,389. Timing ignition; carburetters. F.A. KANE, G. F. OBERRENDER and E.R. POSNACK. Dec. 6, 1968, [Dec. 8, 1967], No. 57950/68. Heading G1B. An electrical operating means 22 is electrically connected to the generator 100 associated with an internal combustion engine, (not shown) to actuate electro-mechanical means 21 whereby when a valve member (not shown) is operatively brought by the electro-mechanical means to its open position the engine intake manifold will be in communication with the distributor vacuum actuator (not shown) so that the vacuum in the manifold will operatively draw the actuator into a spark advance position. When the throttle pedal 26 is depressed to the cruising range the increased generator speed will energize the relay member 84 and cause the arm 86 to be attracted to the core 85 thereby bringing contacts 88, 89, 90 into mutual engagement. At the same time the cruising portion 140 of the cam 134 will be brought into operative engagement with the roller 138. Consequent engagement of the contact blades 131, 132 will accordingly close the circuit through the coil 130 of the solenoid 21 causing the core 64 to be actuated so as to operate the spark and air control valve (not shown) thereby advancing the spark and drawing auxiliary air from the air cleaner into the intake manifold. When the throttle pedal is further depressed to the high speed range at which cam portion 141 is in engagement with the follower roller 138 the three blade 131, 132 and 133 will be mutually separated hence even though the relay switch 87 is still closed both relay circuits will be broken. The respective cores 27 and 64 of both relays will thus instantly snap down into inoperative positions. When the throttle pedal is released to decellerate the engine to cruising speeds the resultant operative engagement of the contact blades 131,132 will again close the circuit through the coil 130 of the solenoid 21. The spark advance and auxiliary air controls are thus set into operation. These controls in addition to effecting the efficient burning of fuel drawn in at partial throttle conditions also serve to effect the burning of the residual rich mixture in the intake manifold drawn in during the previous wider open throttle conditions when the vehicle is further decellerated, as long as the engine speed is above a predetermined critical speed the armature 86 will still be held down. The circuits through both solenoids 20, 21 will thus be closed and all four controls will be in operation to wit the spark advance the auxiliary air the float bowl main jet and the idle shut off controls.

Channel 19 is used for supply of pressure material which may contact the article 34 to the body of the cylinder. The pressure producing fluid is forced through passage 21 into the space 22 between tubular part 14 and the elastomeric bag 15 and transmits pressure through the bag to the pressing fluid. Perforated plate 17 keeps the article 34 out of contact with the elastomeric bag. The yokes 1 of a press stand maintain the closure members in the tube when pressure fluid is applied. In an alternative embodiment the elastomeric bag 15 is replaced by a piston sliding in tubular part 14.

Abstract: 1,257,852. Commutating controlled rectifiers; inverting. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 24 April, 1970 [29 May, 1969], No. 27379/69. Heading H2F. In a commutation circuit for a controlled rectifier (e.g. CR1) having a commutating capacitor C3 and a switching device CR7 for diverting current in an inductor L1 from the main controlled rectifier CR1, the inductor L1 is bridged by one winding of a saturable transformer T1, arranged to undergo a voltage time integral substantially the same as that of L1, another winding of the transformer being arranged to return surplus energy in L1 to the supply terminals 1, 2. As shown in Fig. 3, the invention is applied to the commutation of thyristors CR1 . . . CR6 of a three-phase bridge inverter. The transformers T1, T2 remain saturated after each commutation. One of the main thyristors (e.g. CR1) may be turned off by triggering commutating thyristor CR7 so that commutating capcitor C3 (charged by a previous commutation) can turn off CR1 by providing reverse current therethrough. L1 is initially shortcircuited by the saturated impedance of T1, but when T1 comes out of saturation, energy across L1 is transferred via diode MR7 to the D.C. supply. Reactive current is returned to the D.C. supply via diodes MR1 . . . MR6 and transformers T1, T2. In Figs. 5α . . . 5d (not shown) transformers T1, T2 are biased by bridging diodes MR7, MR8 by resistance or by means of separate biasing windings. In Fig. 6 (not shown) the right hand side of T1 is connected across L1 via a further thyristor, triggered by a circuit responsive to the voltage between point B and the left hand side of L1. In Fig. 6 (not shown) a further saturable transformer is interposed between the right hand of L1 and the cathode of MR9. Single phase inverters.-In Fig. 9, the invention is applied to an inverter comprising a bridge of four thyristors CR1 . . . CR4 having the commutation capacitor C1 across the load L. Saturable transformers T1, T2 may have a common core.
