IPC: G01G9/00
Filed: 1969-12-30
Abstract: 1,273,067. Transistor switching circuits. R. G. HUSOME. 30 Dec., 1969 [15 Jan., 1969], No. 63171/69. Heading H3T. [Also in Division G1] In a circuit for operating a solenoid S for a predetermined time, if the duration of an input pulse lies outside certain pre-set limits, a positive-going leading edge is initiated by wire 30 leaving pin 40, which causes transistor Q1 to conduct, thereby cutting off Q2, Q3 and Q5. Capacitor C1 charges through R1 and C2 through R2 but at a slower rate, while Q3 removes the short across thyristor SCR-1. If the pulse terminated by 30, 40 reconnecting is of the correct duration, Cl will have charged sufficiently long for the potential of the emitter of unijunction Q4 to have risen enough for it to conduct, and feed a firing pulse, to SCR-1, the fall in anode potential allowing substantially complete discharge of C1 over diode D1 As a result, when Q2 conducts again, the pulse developed by C1 discharging through R3 is insufficient to fire SCR-2, while the conduction of Q3 quenches SCR-1 at its anode. If the pulse terminates before the pre-set limit, Cl will not have been substantially discharged from Q2 conducting, the pulse developed across R3 is effective when fed over D2 to fire SCR-2, causing S to operate. If the pulse length exceeds the preset limit, C2 will have charged sufficiently for Q6 to conduct and feed a pulse over D3 to fire SCR-2. Limitation of duration of operation of S. In the normal state SCR-3 conducts, the low anode potential maintaining mean Ne extinguished. When SCR-2 fires, the fall in anode potential, applied over C4, quenches SCR-3. C4 now charges over R8 until Ne ionizes, whereupon SCR-3 fires and extinguishes SCR-2 so that S releases.

Title: Error detection
IPC: H04L1/08
Filed: 1978-11-01
Abstract: Repeatedly transmitted data blocks comprise groups of coded data pulses each group representing respective items of message information, and including a parity bit for error checking the group. Each information block comprising a plurality of groups has transmitted with it a plurality of error detection bits which can be used for error checking the information block as a whole, using a CRC. The data receiver arrangement comprises a data acquisition circuit DAC to which an incoming data stream DS is applied. The data stream PS is fed to a parity bit group error detector PBD which error checks each group of coded data pulses, error-free groups only being stored in a data store ST from which they can be applied to a utilisation device UD. A "whole message" error detector WMD error checks a stored information block as a whole using the CRC error detection bits. Thus an entire block need not be received error free before any group is stored, migration of errors amongst the group as blocks are repeatedly received being prevented. Application is to teletext transmission. <IMAGE>

Title: Measuring the thickness of metallic films on insulating substrates
IPC: H05K3/42
Filed: 1979-07-16
Abstract: An automatic thickness analyzer is provided which automatically measures the thickness of a metallic film deposited on an insulating substrate e.g. plated through holes of printed circuits. A direct current increasing at a constant rate 125, 150 is applied to the conductors of a plated-through hole 350. If the metallic film burns out before the maximum output of the analyzer is achieved, the value of the current corresponding to the burn-out current is captured and held by circuit 200 and the held valve applied to a display meter 250 until it is manually reset by 325. An empirical relationship allows automatic conversion of the burnout current to the corresponding thickness of the metallic film. Burn-out shutdown circuit 275 responsive to the burn-out current inhibits the sample and hold circuit 200 and inactivates the current generator 150. If the metallic film does not burn out before the maximum current capacity of the analyzer is reached, current limit shutdown circuitry 300 is automatically activated. <IMAGE>
