Title: Testing arrangements for intelligence storage equipment
Inventor: WEIR DONALD ADAMS
IPC: G11C29/00
Filed: 1953-03-25
Abstract: 737,498. Digital electric calculating-apparatus. STANDARD TELEPHONES & CABLES, Ltd. March 25, 1953, No. 8232/53. Class 106 (1). Intelligence storage equipment comprises a memory device subdivided into a number of separate storage sections and a test section, recording and reading means associated with the memory device and arranged to co-operate with the sections, a control circuit associated with the recording and reading means and arranged to perform a sequence of operations in co-operation with the respective storage sections, means responsive to the bringing of the test section into operative relation with the recording and reading means to initiate a test sequence of operations by the control circuit, means for checking the test sequence and means for indicating if the test sequence is not correctly performed. In a first embodiment the equipment comprises a magnetic drum memory 1, Fig. 1, having read/record heads 5, 6, 7 cooperating with tracks 2, 3, 4. Each track is divided into a number of individual sections which need not be of equal length, the beginning of each section being defined by signals on a marker track 9, which signals are fed to a counter MPC. Each possible element position is defined by signals on a clock track 10, which signals step on a counter CPC to register the number of elements in each section before being zeroized by a signal from track 9 marking the beginning of the next section. In the present example the eleventh (last) section of each information track 2, 3, 4, &c., is used for testing purposes. The energization of the eleventh section of the counter MPC opens a gate G12 to allow the reading of this section of the track to pass to a testing device 13. Information is recorded in each section in binary code and, after being picked up by the reading head, is either returned to the record surface unchanged or, if a signal is present on the incoming line associated with the section under examination, the binary value is increased by one by recording the reverse of each binary digit received up to and including the first zero and thereafter recording the digits unchanged. The test section, however, provides only one binary digit position, and since a signal T, representing an incoming line signal, is provided permanently at a gate G11, the binary digit in the test section alternates between " 1 " and " 0 " continuously. These alternations may be compared with the alternations of a trigger circuit operated by the zeroizing pulse of the counter MPC. Any disagreement would give an output to operate an alarm 14. A single common control circuit 8 may be associated with a number of tracks in turn by employing an additional " track counter " (Fig. 2, not shown). Other embodiments are described in which the memory unit consists of (1) a mercury delay line, (2) a CRT-type memory, (3) a matrix of saturable magnetic cores, and (4) a matrix of ferroelectric elements.

IPC: H05B41/32
Filed: 1949-03-25
Abstract: 661,779. Ignition systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 17, 1950 [March 25, 1949], No. 8250/49. Class 7(iv) [Also in Group XXXV]  An ignition system includes a condenser 20 charged to a high voltage from a low voltage D.C. source 11 by means of a pulse transformer 17, 18, a make and break contact device 16 in the transformer primary circuit, a spark gap 21 in series with the transformer secondary and condenser under charge and a large condenser 19 shunted across the contacts to ensure at contact make an impulse voltage greater than that at break and thereby reduce the possibility of the condenser 20 discharging back over the spark gap 21 upon contact break after receiving a charge on contact make. The transformer windings are closely coupled to ensure rapid build-up of the charging current upon the spark gap breaking down and a resistance 22 is preferably included in series with the spark gap, remote from the transformer secondary, to reduce high frequency transients. To further decease the peak valve of the impulse voltage at contact break a resistance or condenser or both in series may be shunted across the transformer secondary 18 and a resistance may be shunted across the transformer primary 17. This discharge circuit. to the spark plug 25 includes a spark gap 23 of breakdown voltage lower than that of gap 21 and an inductance 24 to limit the peak current. A resistance 26 is preferably shunted across the plug to protect the apparatus in the event of plug removal. The make and break device may be camoperated but preferably of the tuned vibrator type having its own driving means such as winding 13.

Title: Improvements relating to automatic weighing machines
IPC: B07C5/20
Filed: 1930-03-15
Abstract: 344,676. Sorting by weighing. SOUTHALL & SMITH, Ltd. and WEAVER, F. W., Villa Street Works, Hockley, Birmingham. March 15, 1930, No. 8436. [Class 143.] An automatic machine for checking the weights of packets&c. comprises an horizontal travelling band, pivoted means situated above the band and arranged to be swung to one side for diverting packets of incorrect weight from the main stream, and a weighing device (over which the packets pass) for controlling the pivoted packet-diverting means. The packets, bottles, &c. i carried by a travelling band. are pushed by a reciprocating plate g on to one or other of two platforms h. Adjacent to each platform is a scale pan l to which the packet is transferred by a pusher j, the scale beam k being temporarily clamped by a camoperated locking lever q. If the packet is too light the scale beam rises when released, and closes the circuit through an electromagnet u. The armature of the magnet displaces a catch x and permits a spring z to swing a pair of parallel deflecting-plates o into a position inclined to the travelling band a. The weighbeam is again clamped by its locking lever q and the packet is pushed off the scale pan on to the travelling band by a plunger m. The inclined deflecting plates o then divert the light packet off the band into a collecting receptacle. If the packet is of correct weight, the scale beam, when released, fails to rise and the deflecting plates o remain parallel to the travelling band, the packet then being carried forward to the delivery position. Instead of the duplicate arrangement described, a single scale beam and its co-operating parts may be used. The machine may be adapted to reject excessively heavy packets instead of, or as well as, those of underweight. Specification 262,078, [Class 143, Weighing-apparatus], is referred to.

Title: Rotary hydraulic machines, such as pumps and pump-turbines
IPC: F03B11/00
Filed: 1966-02-25
Abstract: 1,137,203. Centrifugal pumps; hydraulic turbines. DOMINION ENG. WORKS, Ltd. Feb.25, 1966 [March 12, 1965], No.8452/66. Headings F1C and F1T. A rotary hydraulic machine comprises a stationary housing containing a bladed impeller having a shroud, at least one substantially annular space being formed between the shroud and the housing, means for introducing gas to the space, at least one annular rib extending outwardly from the shroud to provide a radially outwardly extended path of flow from the space to the impeller intake, and means for withdrawing gas and liquid mixture disposed adjacent the rib and axially on the side of the rib towards the space, whereby the rib acts as a barrier to the flow of gas into the impeller inlet from the space but not into the withdrawing means. The pump or pump-turbine shown in Fig. 2 is of the type in which air is supplied to an annular space 27 adjacent an impeller shroud 2 to reduce fluid friction. Water from the discharge side of the impeller flows continuously through annular passages 35, 36, 37 to form sealing water for a seal 7. Excess air supplied to the space 27 is discharged via annular passages 38, 39 to join the sealing water in passage 36. The sealing water conveys the air via passage 37 and seal 7 to an annular chamber 11 where the air-water mixture is rotated by the frictional drag of an annular surface 18 of a radially extending annular flange 10 on the impeller shroud 2. This rotation builds up pressure in the mixture and causes partial centrifugal separation of the air from the water, whereby the water leaking around the flange 10 and so returning to the inlet 5 is free from air, the remainder of the mixture being withdrawn through a conduit 13 to a manifold and thence to a separator from which the air can be discharged to atmosphere and the water returned to the machine intake. In the case of a multi-stage machine, the separated air and water from H. P. stages can be re-used in the L. P. stages. The invention may be applied to a pump handling crude oil.

Abstract: 597,584. Electric indicating systems. STANDARD TELEPHONES & CABLES, Ltd. April 13, 1945, No. 9286. Convention date, April 20, 1944. [Class 40 (i)] [Also in Group XXXVI] In a meter of the resultant field type, the rotor is adapted to be locked by separately energized means released in dependance on the energization of the meter. As shown, applied to a radio direction-finding system utilizing two interrupted overlapping radio beams transmitted by a ground station, two pulse trains 3, 4 derived from the radio receiver-amplifier detector 2 are segregated in a discriminator 5 and applied over leads 6, 9 to the series connected coil pairs 7, 8 and 10, 11, the direction of the resultant magnetic field produced by the coils being indicated by a pointer 23 on a rotatable shaft 21 carrying a bar magnet 24 rotating substantially in the plane of the coils. The magnet is keyed to the shaft 21 between a nut 31 and resilient washer 30 so that it rotates with the shaft but is capable of a limited rocking movement relative thereto. Two magnetic rings 40, 41 secured to the insulating frame elements 13, 17, 18 coaxially with the shaft 21 are joined by a magnetic yoke 42 carrying two coils connected in opposition. One of these coils is energized from a battery 46 and the other from the receiver detector 49. Normally, with the coils 7, 8, 10, 11 energized, both the coils carried by the yoke 42 are energized and cancel out the effect of each other. When no signals are present in the receiver, only the battery fed coil on the yoke 42 remains energized and the consequent magnetic field between the rings 40, 41 rocks the magnet 24 into engagement with the frame extensions 37, 39, whereby the movement is frictionally held and its reading persists until the instrument is again energized. Fig. 6 (not shown) illustrates a known way of deriving from a pair of directional antennµ the two voltages for application over leads 6, 9 of Fig. 1.

Abstract: 1301697 Transistor monostable circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 Feb 1970 [1 March 1969] 9375/70 Heading H3T A monostable multivibrator as shown is characterized in that the emitter of transistor 3 is connected to the base of transistor 1, while the base of 3 is coupled to a terminal 14 having on it a reference voltage -V R , this terminal also being connected to the emitter of 1 via a threshold element 16 whose theshold value is equal to the sum of the base of emitter function voltages of transistors 1 and 3. The pulse width is varied by a rheostat 13 connected either as shown or in the collector circuit of 3. In the stable state, 1 is bottomed, thereby charging capacitor 4 with the polarity shown; 2 and 3 are off. An input pulse at 17 is differentiated by 18; its leading edge has no effect but its trailing edge biases 1 off and tends to turn 3 on. 1 going off turns on 2, and this causes the emitter of 3 to go more positive and so definitely turn on. Capacitor 4 then discharges to the supply via 2 and 3 in series at a rate determined by the setting of 13. When it is sufficiently discharged the circuit switches back to its stable state. The output signal 21 is taken from terminal 20. The components other than the capacitors and variable resistor 13 may be made in integrated form. The threshold device 16 enables very short output pulses to be obtained.
