Title: Apparatus for the measurement of short time intervals
IPC: G04F10/00
Filed: 1972-10-28
Abstract: 1389894 Measuring short time intervals; testing semi-conductor devices FERRANTI Ltd 25 Oct 1973 [28 October 1972] 49796/72 Heading G1U A time interval representing a delay in a semiconductor circuit is measured by applying two signals to the device, sampling its output, using the output to control the delay of one signal with respect to the other and displaying the duration of the delay. The "set up" time of a D-type bi-stable X is measured by using synchronized signals SG1 and SG2 as the clock and data inputs respectively these having fixed and variable delays FD and T respectively. The bi-stable output is sampled by a discriminator SD gated by a signal SG3 which precedes a reset signal SG4. The discriminator output is sensed by a circuit C which controls the delay T. If the clock and data signals are too close, X does not change state and delay T is shortened to make the data pulse earlier. At the critical time difference, control circuit C senses the change in bistable output to stop any further variation and the time interval is displayed, DP. By inverting the SG2 signal, the "hold" time of the bi-stable, i.e. the time after the clock pulse that the data pulse must still be present, can be measured. If the two delayed signals are gated together and applied to the clock input Figs.3 and 4, (not shown) the minimum necessary clock pulse width can be determined for bi-stables or monostables.

Abstract: 1446225 Atomizers DECAFIX Ltd 21 Oct 1974 [26 Oct 1973] 49871/73 Addition to 1366890 Heading F4T An atomizer for fuel oil comprises a convergent annular chamber 19, a coaxial inner convergent gas nozzle chamber 17 and a coaxial rigid annular deflector 18, which has a gas bleed disc 22 leading to a further deflector 21, which deflects a gas stream across the outer face of the first deflector. In operation, compressed air is fed through passages 13 to chamber 17 and is emitted at sonic velocity along the outer surface of deflector 18 where it increases to supersonic velocity. When the gas approaches the curved portion of deflector 18 the pressure increases and the velocity decreases to thus produce shock waves. Liquid to be atomized is fed through passages 12 to chamber 19 and thence as a film into the gas emitted from chamber 17. Gas is also fed through passages 23, 22, 24, into annular space 25 and thence between deflectors 18, 21, so as to prevent build-up of carbon on the face of deflector 18.

Filed: 1967-11-10
Abstract: 1,180,147. Rolling. COMPAGNIE DES ATELIERS ET FORGES DE LA LOIRE (ST. CHAMOND FIRMINY, ST. ETIENNE, JACOB - HOLTZER), and HYDROMECANIQUE ET FROTTEMENT. 10 Nov., 1967 [19 Dec., 1966], No. 51334/67. Heading B3M. [Also in Division G3] Apparatus for regulating the thickness of a rolled product is positioned in a roll stand either between a lower chock and the roll housing or between an upper chock and a screw-down, and comprises a piston 1 which is acted on by a chock E and moves within a support 2. The space between the piston and support is filled with a liquid 5 into which extends the end of a plunger piston 4. The position of the piston 4 is controlled by a servovalve 7 and an hydraulic actuator 6. The servovalve is in turn operated by a unit 13 in response to the measured position of piston 4 and the pressure of the liquid 5. Any change in the roll gap leads to a movement of the piston 1, and a proportional change in the liquid pressure. The piston 4 is thus caused to move axially. The liquid pressure is measured at 11, and the actual position of the piston 4 is measured at 10 by a position detector. Signals corresponding to these measurements, together with a zero shift signal, are fed to the unit 13. The unit controls the servovalve 7 such that the piston 4 is moved in a sense to compensate for the original change in pressure in the liquid 5. A diaphragm 12 positioned between the chock E and piston 1 transmits vertical loads while absorbing lateral and rocking forces produced by the chock. The liquid 5 consists of a mixture of 20 parts by weight of calcium-soap grease, 10 parts of nicron size graphite and 2 parts of sodium tri-stearate. A second plunger piston may be used which is forced out of its bore in the event of excessive rolling pressure.

Title: Data processing systems
Inventor: NICKEL F
IPC: G06F15/16
Filed: 1973-11-06
Abstract: 1451349 Data processing systems SPERRY RAND CORP 6 Nov 1973 [6 Nov 1972] 51377/73 Heading G4A The system has a central processor and a number of partitionable units, so that the system may be partitioned into two or more substantially independent systems which process different applications, such as real time, batch, and maintenance. The partitionable units include multi-access sub-systems (MAS) for accessing peripherals which can be assigned to more than one application at a time. Each unit is associated with a switch for each application and with a switch for placing the unit off-line. The switches cause signals to be generated to indicate, e.g. by means of a lamp, to which of the applications the unit is switched. An external interrupt signal (EI) is generated when any switch is operated. The MAS switches are interlocked so that, for any MAS unit, setting any application switch resets the off-line switch, whereas setting the off-line switch resets all the application switches. The switches for the remaining partitionable units are also interlocked so that, for any one unit, setting any one application switch resets all other application switches and the off-line switch, whereas setting the off-line switch resets all the application switches. As disclosed, each switch is a double pole double throw switch. One half of the switches pertinent to a particular application are serially connected so that during switching the connection is broken briefly, causing generation of the EI signal. There is a separate EI generator for each application. The EI signal is passed to that or those input/output access units (IOAU) which have been selected (by operation of the switches) for the particular application. The relevant IOAU responds by examining status  words, which indicate which units are assigned to each application, in order to determine the nature of the change in partitioning called for by the switch operation, and the new partitioning configuration is recorded in the status words. Software in the partitioned system affected makes the program changes necessary to adjust to the new partition status.

Abstract: 1332006 α-Strontium acid phosphate PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 3 Nov 1970 [6 Nov 1969] 52256/70 Heading C1A [Also in Division C4] In the method of manufacturing α-strontium acid phosphate (α-SrHPO 4 ) by mixing aqueous solutions of a strontium salt and a secondary phosphate at between 40‹ and 100‹C., watersoluble aminopolycarboxylic acid or water soluble salt thereof is added to at least one of the solutions, the aqueous medium from which the α-strontium acid phosphate is precipitated containing 10<SP>-3</SP> to 100 mg. mol of the aminopolycarboxylic acid of salt per litre. Specific salts are strontium chloride, strontium nitrate, or strontium acetate ,and ammonium or alkali metal secondary phosphates. The solutions may be mixed at a chemically equivalent rate, maintaining the concentration of aminopolycarboxylic acid or salt in the precipitation vessel constant. In one embodiment the precipitation vessel contains an aqueous aminocarboxylic acid or salt solution prior to addition of the two solutions. In a further embodiment, 1-10 vol. per cent of the required strontium salt solution is introduced into the precipitation vessel before simultaneous addition of the two solutions, thus avoiding excess of hydrophosphate ions. In the examples diammonium hydrogen phosphate (1À75 molar) and strontium chloride (1À75 molar) were supplied at 25 ml/min. to a precipitation vessel containing 1 litre of distilled water at 85‹ C. which was being stirred. Aminopolycarboxylic acid was present in the water, and twice that concentration was present in the strontium solution. Aminopolycarboxylic acids specified include, nitrilotriacetic acid, ethylenediamine tetra-acetic acid, 1,2-diaminocyclohexane tetra-acetic acid, and diethylenetriamine penta-acetic acid. Particle sizes of the α- strontium acid phosphate are mostly between 6 and 20 microns.

Abstract: 1,106,459. Automatic phase control systems; radio navigation. A. C. COSSOR Ltd. 17 Dec., 1965 [24 Dec., 1964], No. 52438/64. Headings H3A and H4D. In an arrangement for providing second oscillations phase locked to first oscillations, first and second pulses are produced when a part of each cycle of the first and second oscillations respectively occurs, the part for the second oscillations is separated by half a cycle from the corresponding part of the first oscillations, and a coincidence detector supplies an output signal to the second oscillation generator to prolong a cycle of its oscillations by the time required for the first and second oscillations to become phase locked. Phase locking for oscillations of different frequencies means that all nodes at which the waveforms are changing in the same sense are time-spaced a whole number of periods at the lowest common multiple frequency. The embodiment relates to apparatus for testing airborne radio navigation receiving devices for I.L.S. and marker beacons, the I.L.S. system operating on differential depth of modulation (D.D.M.) of 90 c/s. and 150 c/s. modulations of the same carrier frequency. In Fig. 2 a 900 c/s. a stable multivibrator feeds two sets of dividers, each incorporating a divide-bytwo bi-stable multivibrator 16, 18. 90 c/s. and 150 c/s. square waves are taken to emitterfollower pairs VT5, VT6, and VT7, VT8, respectively. The phase-locking circuit 19 depends on the coincidence of a positive-going step in the 90 c/s. waveform at the emitter of transistor VT6 with a negative-going step in the 150 c/s. waveform at the emitter of transistor VT8; at this time the collector of transistor VT3 is also going positive. The 90 c/s. signal from the emitter of transistor VT6 is differentiated and the ensuing short pulses are fed to an AND gate formed by diodes D1, D2; the 150 c/s. signal from the collector of transistor VT3 is likewise differentiated and then passed to the AND gate. When the waveforms are unlocked, a point 55 goes positive to switch on transistor VT9 via a diode D3. A negative pulse then passes to switch off transistor VT4 to bring the waveforms into phase. The square waves are changed into sine waves by filters 20, 21, and combined in pre-set amplitude ratios via tapped auto-transformers 22, 23. The radio navigation testing apparatus as a whole, incorporating the phase-locking arrangement described above, includes selectable provision of marker, localizer, and glide path signals, Fig. 1 (not shown). A remote control switching arrangement for setting the switches in the testing apparatus is described, Fig. 4 (not shown).
