Abstract: 1,140,760. Electric calculators. SANDERS ASSOCIATES Inc. 27 June, 1967 [27 June, 1966], No. 29685/67. Heading G4A. Two or more digital numbers are additively combined by a circuit comprising digital-toanalogue converting stages 18-24 each of which receives corresponding digits of the numbers and produces an analogue signal corresponding to an additive combination of those digits, the stages being interconnected to produce an analogue output signal corresponding to an additive combination of weighted functions of the outputs from the stages 18-24. The particular additive combination obtained depends on the outputs of supplies E 1 -E 4 , two simple examples being ¢(A + B) when E 1  = E 3  = + 1 volt, E 2  = E 4  = 0, and A-B when E 1  = E 4  = + 1 volt, E 2  = E 3  = - 1 volt. If linear ramp voltages are produced by selected supplies E 1 -E 4 , the resultant output voltage may be made to vary linearly between values representing A and B, e.g. for display on a C.R.T. The numbers to be combined may be in binary, ternary, octal, binary-coded decimal or other forms. Fig. 1 shows a circuit for two binary-coded numbers A, B. Taking the first example quoted above, a " 1 " digit from register A or B results in an output at 46 of 1, 2, 4 or 8 units depending on which of stages 18-24 the digit is applied to. If corresponding digits of the A and B numbers are both " 1," the resulting output at 46 is 2, 4, 8 or 16 units.

Filed: 1972-06-26
Abstract: 1379642 Gyroscopes ANSCHUTZ & CO GmbH 26 June 1972 [24 June 1971] 29887/72 Heading G1C A north-seeking gyro device comprises a gyrosystem 10, 12, 16, having freedom of movement in three axes, supported by a strip 18 in a support body 30. When a horizontally rotating rotor 16 is displaced from the meridian its axis of rotation 14 tilts and precession of the gyro-system 10, 12, 16 about the meridian results. A motor 44 then slaves the support 30 to the gyro-system 10, 12, 16 by utilizing a mirror 48 and a photo-electric device 50 which supply a signal to the motor 44 proportional to the azimuthal difference between the support 30 and gyro-system 10, 12, 16. The common vertical oscillatory rotation of the gyrosystem 10, 12, 16 and the support 30 is kept constant by controlling the oscillatory rotation of the gyro-system 10, 12, 16 by means of a counter torque generator 22, 24. Since in uncontrolled precession the velocity and angle of tilt of the rotor 16 increases as the meridian is approached and decreases when the meridian is passed, the force required to keep the angle of tilt of the rotor axis 14 and the angular velocity of the precession constant varies from a maximum at the extremities of the precession to zero at the meridian. Thus a zero output from a constant value controller 54 which controls the generator 22, 24 coincides with the gyro-system 10, 12, 16, and hence a theodolite 36 mounted on the support body, being directed along the meridian. This null output is detected by a zero sensor 62 causing, for example, a breaking of contact 64 so as to stop the motor 44 and hence movement of the theodolite 36. In a modification the gyro-system is not supported as a pendulum, the supporting moment generator then being effective about the Y axis being controlled by for example, a clinometer. A further torque generator is then required which acts about the vertical axis. For exact indications of the meridian a time switch is provided to ensure that the spin vector of the rotor 16 forms a sufficiently large angle with the meridian when the rotor has reached full speed. This then allows a constant speed to be established on the precessing gyro-system.

[Class 58.] Corn is " popped " in a heated rotatable drum having a wirework periphery and containing a second drum with larger perforations within which is arranged a conical screen the wider end of which forms a discharge opening at the side of the drum. The drums are contained within a casing 9 which carries bearings for a shaft 13 that is driven by a reversible electric motor. A clutch member 16 pinned to the shaft is adapted to be engaged by a co-operating member 17 secured to a head 19 closing the rear of the main drum 18 which is slidable and rotatable on the shaft 13. The front head of the drum is comprised by a dished annular member 20 that carries a handle 26 and a latch member 29 by which the drum can be held with its clutch member locked in engagement with or free from the clutch member 16. The drum 18 has a fine wire screen 21 as periphery upon which the grains of corn are heated till popped, the heating being accomplished by a gas burner 42 provided with finger like downward extensions 43 between which fragments of burning husk may fall. A second screen 32 of larger mesh than the screen 21, arranged within the first drum, is provided with a gateway 33 that is situated in advance of a plate 34 extending to the screen 32 at one side of slotted opening 22 to the passage between the screens ; through this gateway access is obtained to the interior of the second drum. Another gateway 37 is provided in the periphery of the conical screen 36 which is formed of sheet metal having large openings therein which however are not large enough to permit the passage of popped grains. In use the drums are turned till the gateway 33 is at the bottom and a charge of grain introduced through the open side of the coned screen 36 this grain immediately falling through the gateway 37 on to the screen 32. The drum is then rotated in the direction indicated the unpopped grains falling on to the screen 21, while the popped grains collect on the screen 32 thence passing to the coned screen 36 and outwards through the side opening. To remove unpopped grains after a sufficient length of time for roasting has elapsed the drum is rotated in the reverse direction the grains thus being thrown out through the slot 22.
