Patent GB-1129294-A (GB)
Title: Gyroscopic system
Inventor: GATES ROBERT LEE
IPC: G01C19/38
Filed: 1965-10-18
Abstract: 1,129,294. Gyroscopic apparatus. TRW Inc. Oct. 18, 1965, No.44045/65. Heading G1C. A gyroscopic system for the determination of azimuth alignment comprises an inertial gyro 10 having a rotar 11 with a spin axis and orthogonal input and output axes, the spin axis being located in use at the local latitude angle with respect to the local horizontal plane and being aligned approximately in the local meridian plane, a motor 35 for locating the input axis in a first position in the local horizontal plane and subsequently in a second 180 degrees displaced position in this plane, the total gyro drift rate being measured with the input axis in each of the first and second positions, this rate being dependent on both misalignment of the spin axis with the meridian and error torques in the gyro, the two measured drift rates being summed in a computer 29 to cancel out the effects of the error torques and enable the misalignment angle to be determined. The gyro 10 is a single degree-of-freedom gyro and is provided with a pick-off to detect precession of the rotor. The pick-off signal controls a torque signal generator 25 which develops a current fed to a torque on the gyro which precesses the rotor back its null postion. This current is passed through a resistor 26 to generate a voltage across the resitor which controls the frequency of an oscillator 27 in dependance on the develped voltage. This frequency is thus a measure of the torque required to maintain the rotor 11 in its null position and thus of total gyro drift rate and is measured by a counter 28 the output of which is stored in the computer 29. A control 24 controls the action of the counter 28 to 100 second periods for each of the two 180 degrees displaced positions of the gyro input axis and the control 24 also actuates a rotation control for the motor 35 between the 100 second periods. The angular position of the gyro about its spin axis is monitored by an E-core pick-off 36 co-operating with one of two iron slugs 37, 37a mounted on the gyro case. When the pick-off 36 detects that the gyro has reached one of the two possible 180 degrees displaced positions for the input axis a position control 33 stops rotation of the motor 35 and electrically cages the gyro. The total gyro drift rate is measured for each of the two positions for the gyro input axis in a continuous sequence and the computer 29 algebraically sums the drift rate values to give a value for the misalignment angle between the local meridian plane and the gyro spin axis thus giving the desired azimuth alignment. A desired rotation of the gyro about its spin axis between the two refered to positions may be effected manually.

Abstract: 995,165. Paper-folding apparatus. HAMILTON TOOL CO. Nov. 21, 1962 [March 15, 1962], No. 44086/62. Heading B6H. In a rotary folding-apparatus for zig-zag folding a paper web and comprising two cylinders 12, 14 having mounted thereon co-operating folder-jaws 32, 34 and a tucker blade C, the tip of the blade is moved rearwardly relatively to its cylinder during engagement of the blade with the jaws. The carrier block 36 for the blade is mounted in a recess 24 in the cylinder 14 and has a slot 39 in which a clamp-bar 40 is secured by a bolt 42, a rounded corner 50 of the bar gripping the inner edge of the blade so that the blade can flex. The shaft 38 of the block 36 is rocked against the action of a spring 62 to cause the rearward movement of the blade tip, by a fixed cam 58 acting on an arm 52 fixed to the shaft 38, the cam 58 also acting to advance the blade tip when it is disengaged from the jaws. One jaw 34 is fixed to cylinder 12 and the other jaw 32 is replaceably-secured to a pivoted arm 28 spring urged to close the jaws and operated in known manner to open them. The gripping surfaces of the jaws have a greater frictional grip on the paper than the surface of the blade so that the blade does not tend to pull the fold outwardly as it is withdrawn and the outer part of each jaw is radiused. Each cylinder has one blade and one pair of jaws for producing one zig-zag folder per revolution, but additional jaws and blades may be provided for producing two zig-zag folds per revolution.

Title: Charged particle beam apparatus
IPC: H01J37/04
Filed: 1975-10-28
Abstract: 1523297 Automatic current control STEIGERWALD STRAHLTECHNIK GmbH 28 Oct 1975 [29 Oct 1974] 44437/75 Heading G3R The current in a charged particle beam is regulated by continuously measuring the emission current of the particle source, correcting the measured value by multiplying it by the ratio of workpiece current to emission current when the beam is first directed on to the workpiece, and comparing the corrected value with a desired workpiece current to produce a current control signal.  As shown, electron beam apparatus 10 for boring, cutting or welding a workpiece 12 includes a cathode 14, anode 18 and Wehnelt cylinder control electrode 16, and is energized from a high voltage source 30. A deflection device 24 initially directs the beam on to a collector 26, but a start signal from a source 42 causes the beam to strike the workpiece 12 after passing through a coil 28 which produces a pulse with an amplitude proportional to the instantaneous value of the current striking the workpiece. This pulse is fed to a regulator 36 which effectively divides its amplitude by the total beam emission current as sensed by a resistor 32, thus producing a value for the beam current efficiency which is multiplied by the emission current during operation so as to provide a continuous signal representing actual workpiece current. This signal is compared with a reference voltage from a source 38 using a PI regulator circuit which feeds a signal to a control voltage source 34 connected to the current control electrode 16. Digital counting and logic circuitry for carrying out the functions of the regulator 36 is described with reference to Fig. 2 (not shown), and it is stated that analog circuitry may also be used.

Filed: 1974-10-15
Abstract: 1490205 Colour television INDESIT INDUSTRIA ELETTRODOMESTICI ITALIANA SpA 15 Oct 1974 [22 Oct 1973] 44725/74 Heading H4F The phase of the reference subcarrier oscillator 10 in a PAL colour television receiver is controlled by controlling a phase shift circuit 8 connected between a burst gate 2 and oscillator 10, such control being carried out in response to a signal derived from the output of at least one of the demodulators 3, 4. Burst gate 2 is opened to pass only every second colour burst and is controlled by a circuit 6 receiving line repetition frequency pulses 5 and a signal from a half-line-frequency generator 7 which also controls a PAL switch 13. The output of B-Y demodulator 3 is fed via a half-line-frequency selective circuit 17 to a circuit 18 which provides the control signal for phase shift circuit 8 and resets generator 7 if it is operating in incorrect phase. Circuit 18 may also receive a second input from a second half-line-frequency selective circuit 17<SP>1</SP> connected to the output of R-Y demodulator 4. The circuit 18 includes two peak detectors (21, 22, Fig. 2, not shown) connected with reversed polarity to the output of frequency selective circuit 17; if circuit 17<SP>1</SP> is included it is connected to two similar peak detectors (21<SP>1</SP>, 22<SP>1</SP>), the outputs of corresponding peak detectors (e.g. 21, 21<SP>1</SP>) being added together. The output of one peak detector (or the corresponding adder) controls two threshold circuits (25, 26) one of which (25) has a higher threshold and shorter time constant than the other and supplies the resetting signal to generator 7 if the generator 7 is operating in the incorrect phase ; such incorrect phase results in the burst gate 2 separating the wrong bursts and oscillator 10 operating at 90 degrees to the correct phase. The second threshold circuit (26) controls a change-over switch (27) to supply the output of one of the peak detectors (or the corresponding adder) to control phase shift circuit 8.
