Title: Signal Processing for measurement of phase difference between light pulses in a series of signal pulses from an optical sensor
Inventor: AUSTIN EDWARD
IPC: G01B9/02
Filed: 2009-10-29
Abstract: There is described a method and apparatus for processing light pulses returned from an optical sensor, wherein the light pulses are applied to two interferometer arrangements, a first interferometer arranged simply to superimpose two pulses and detect a first resulting value, and the other interferometer being arranged to apply a relative phase shift of about n/2 before superimposing the two pulses to detect a second resulting value. The relative phase shift is applied by shifting the phase of one or both of the pulses. The first and second resulting values are divided to give a third value, representative of the sensor state. The state determined may be the instantaneous optical path length of the optical sensor. A seismic sensor array using such an apparatus to process returning pulses is also described.

Title: Improvements in or relating to remote control systems for rotary shafts
Inventor: COPPIN KENNETH JOHN
IPC: G05B19/04
Filed: 1964-03-12
Abstract: 1,048,725. Electric selective signalling. E. K. COLE Ltd. June 10, 1965 [March 12, 1964], No. 10445/64. Heading G4H. A positional control apparatus for a rotary shaft in which a plurality of commutators each with a pair of brush assemblies 180 degrees apart are arranged such that the correct brush assembly is selected according to the reading of the preceding commutator and that in each brush assembly continuity of signal at change of conducting segments is maintained using two brushes. The two brushes may be staggered or aligned with the conducting segments having overlapping portions. In the illustrated embodiment rotary switches define the final shaft position and as each commutator reaches that position, highest value first, a relay is operated to step a plurality of uniselectors whereby the shaft motor is stopped, a relay is operated according as the setting is odd or even and thus determining which of the two brush assemblies of the next commutator should be utilized. The uniselectors are stepped again, the shaft motor operated until that shaft position is reached, the operation being repeated. The three finest settings are determined by balancing a Wheatstone bridge arrangement similar to that in Specification 856,138 in which a contact on a toroidal potentiometer is rotated until its potential is equal to that of the pole of the set switch. The shaft motor is then disconnected, the uniselector stepped to the next position at which the odd or even setting is checked and then stepped to the next position to restart the motor for a rotation set by the next switch. To provide slow movement of the shaft at this stage the motor may be pulsed by a constantly charging and discharging capacitor. The final balance of the Wheatstone bridge is checked at positions 9 and 11 of the uniselectors to check correct positioning of the shaft. The shaft may be used for positioning a machine tool or a body on which work is to be performed.

IPC: E05B37/04
Abstract: 105,487. Chubb & Sons Lock & Safe Co., and Butter, F. J. July 26, 1916. Locks, permutation.- The lock is of the type having co-axial disks set by a single knob which is turned in one direction only a.nd is moved longitudinally after each disk has been set. The disks 32, 33, 34 are frictionally mounted on bosses 31, and each disk has a slot 40 into which the stump 41 on the bolt enters when the combination is set. When the combination is to be changed, a key or tool is passed through the barrel 45 into the slots 40 and, being turned through a right-angle, wedges open the slots, releasing the grip of the disks on the bosses 31, so that while the disks are held, the bosses can be turned to new positions. The disks are set by the fin 29 on the operating-spindle 8 acting on pins 30 within the bosses 31. After each disk has been set, the inward movement of the knob brings the fin 29 to a position clear of the pin 30 corresponding to that disk. After all the disks have been set, the spindle is pressed in farther, and the face of the star-wheel 27 presses back the spring-catch 50 in the bolt-tail 10. At the same time, the star-wheel engages a projection on the bolt-tail, and by turning the knob 15, the bolt 42 is withdrawn. When the bolt is withdrawn, guards 54 pass up behind the star-wheel, locking the spindle 8 and knob 15 in the pressed-in position until the bolt is again shot. The turning of the spindle to set the combination disks is regulated by numbered graduations on the disk 12, which turns with the spindle, and a guide-mark on the fixed mount 11. Special means are provided for regulating the extent to which the knob and spindle are moved inwards as each disk is set in turn. The whole extent of the movement of the spindle is limited by the collar 9.

[Class 40 (v)] The signal detector D of a radio receiver is associated with a rectifier 2, the anode of which is connected to the grids of the frequency changer FC and intermediate-frequency amplifier IF through a path of negligible impedance to direct currents such as the choke 6, whereby these grids are decoupled from the output circuit of the detector D both when the receiver is muted and normally operative. The muting system consists of the rectifier 2, fed with high frequency energy from the anode circuit of the detector D over condenser 3, resistance 5, switch 10 and resistance 8. With the switch 10 on contact 11, normal grid bias from 12 is applied to F.C. and I.F. and the muting is inoperative. On contact 9 the grids of F.C. and I.F. are slightly positive and the receiver is muted. On tuning in a signal of a given strength the diode 2 becomes operative, the rectified p.d. across resistance 5 causing a fall in potential of point 4 to remove the muting ; the diode 2 subsequently feeds A.V.C. potentials to valves F.C. and I.F.
