Title: Improvements relating to calibration arrangements for oscillographs and their application to radio obstacle detection systems
IPC: G01S19/24
Filed: 1944-02-07
Abstract: 592,577. Radiolocation; cathode-ray oscillographs. STANDARD TELEPHONES & CABLES, Ltd. Feb. 7, 1944, No. 2277. Convention date, Dec. 4, 1942. [Class 40 (v)] [Also in Group. XXXVI] A radiolocation system is provided with a vernier oscillograph, the time base sweep of which commences at a selected time after the transmitted or synchronizing pulse and is provided with a train of calibration pulses. The synchronizing pulse 15, Fig. 2, coinciding with the pulse emitted from transmitter 10, Fig. 1, is fed to the combined delay and wave train producing device 20 which comprises a series of oscillatory circuits L1, C1-Ln, Cn. Each circuit is tapped off from the previous circuit between the coil and condenser by connections 21, 22 ... provided with contacts 21a, 22a, &c. The first circuit L1, C1 produces a train of oscillations 31 at contact 21a, which is delayed by a time t1 from the pulse 15, equal to 90 degrees at the oscillation frequency fc. The oscillations 32 of the same frequency fc in circuit L2, C2 are similarly delayed with respect to the oscillations 31 and commence at time t2, equal to 180 degrees, after pulse 15. A series of trains of oscillations of frequency fc, spaced in time, are thus available at contacts 21a, 22a, &c. As shown, the oscillations 35, delayed by a time t5 equal to 450 degrees at the oscillation frequency is selected from the fifth circuit and contact 25a by the movable contact 40, and is fed to a circuit 42 which limits at levels 44, 45, the resulting square wave being differentiated in circuit 46 to produce pulses 50, 51. A limiting circuit 48 operating at level 53 passes the series of pulses 54 to the vertical deflecting system of the cathode-ray tube 14, which is also connected to the receiver 12, to produce the calibration pulses on the time base trace. The pulses from the output of the differentiating circuit 46 are also fed to trigger a multivibrator 61, the output of which is differentiated at 62 to produce a sharp pulse corresponding to the first calibration pulse, which is used to trigger the time base sweep generator 63. Specification 592,574 is referred to.

Title: Servo systems
IPC: G11B5/55
Filed: 1972-01-19
Abstract: 1369155 Automatic control of position INTERNATIONAL COMPUTERS Ltd 16 Jan 1973 [19 Jan 1972] 2602/72 Heading G4H [Also in Division G3] Apparatus for positioning a movable data transducer in relation to a plurality of parallel data-tracks comprises a plurality of servo tracks parallel to the data tracks each track comprising spaced apart discrete signal recordings, the recordings being so arranged that there are sets of at least first, second and third tracks in which the recordings are relatively displaced whilst the recordings of corresponding tracks in different sets are aligned, and a servo transducer mounted for movement across the servo tracks in synchronism with the movement of a data transducer and arranged to be positioned symmetrically with respect to a pair of servo tracks when the data transducer is aligned with a data track, and a coarse positioning control means including means responsive to the signals sensed by the servo transducer in passing from one track to another to generate a track change signal, and fine positioning means responsive to the amplitudes of signals sensed from each servo track to maintain the data transducer aligned with a data track. As shown, the servo transducer 6 applies sensed pulses to a shaping circuit 14 and via a line 15 to synchronize a phase-locked oscillator 16 which provides a clock signal of 3 times the frequency of the sensed pulses of any 1 servo track. The clock signal is passed to a mark circuit 24 which produces the outputs 10, 01, 00 sequentially on lines 25, 26, which are applied with the clock pulses to a gating circuit 27. The output of circuit 14 is also passed, via a level detector, to the set input of a flip-flop 20 and the clock signal, inverted, to the reset input thereof such that the flip-flop supplies a "1" signal to a shift register 21 during a clock pulse duration if a mark is sensed at 6, and a "0" if no mark is sensed. The register 21 has 3-stages and the decoder 21 provides a pulse to circuit 27 at the "011" state of the register. When the head 6 is symmetrically aligned with 2 of the servotracks, the "00" signal at 24 is coincident with the output from 23 and no pulse is passed to counter 12. When a track change occurs the flip-flop output will be 1 clock pulse leading or tagging on the output of circuit 24 and circuit 27 will pass an appropriate count signal to counter 12, the circuit 24 being reset at 30 is in synchronism with the new phase of the sensed pulses. Each secone sensed pulse is inverted at 32 and added to each first pulse to provide a fine positioning analogue signal.

In Fig. 3 the corrugations extend axially and the strip is spot-welded at 17 to the spokes of a hub which extend in a spiral beneath the edges of the strip. For tools of larger diameter, a strip 30, Fig. 6, of corrugated form or having a crimped edge 35, may be interposed between the spokes 32 and the helical joint, the edges of the cutting strip being spot-welded, or continuously welded, to one edge of the strip 30 and the spokes attached to the other.

Abstract: 922,654. Resistors; resistor faults testing. WESTERN ELECTRIC CO. Inc. Jan. 29, 1960 [Feb. 27, 1959], No. 3269/60. Class 37. A method of making a resistor includes forming a resistive path on an insulating base, sensing the resistance per unit length of the path as it is formed, and giving an indication if such varies outside predetermined limits. Irregularities in the resistance per unit length of a resistor formed by cutting a helical groove 46 through a deposited carbon layer 11 are detected during cutting by passing the output from the Wheatstone bridge 37 to the differentiating network 36, which provides output to the amplifier 43 and resistor rejection device 44 only upon the occurrence of a sufficiently marked irregularity. The bridge 37 is adjusted to attain balance at the desired final resistance value. The resistor blank is clamped in chucks 12 by rotation of the pivoted arm 26, and is held against the cutting wheel 22 by counterbalanced arms 19 which can pivot about the splined guide rod 21, and which withdraw the resistor from the cutting wheel, when the Wheatstone bridge output falls to zero, by means of solenoid 32 and armature 33, which are excited when normally closed relay 39 opens. The resistor blank is rotated on its axis by drive shafts 13 and 17 coupled by telescopic shafts 15, and motors 18 also traverse the blank past the cutting wheel by moving arms 19 along rod 21 by a gear mechanism (not shown). The resistor blank may be prepared by heating an insulating base in an atmosphere of methane and oxygen.
