Title: Numerical base translator
IPC: H03M7/12
Filed: 1970-10-05
Abstract: 1321649 Digital computers; radix conversion COMTEC INDUSTRIES Inc 5 Oct 1970 [7 Nov 1969] 47257/70 Heading G4A An apparatus translates digital data from one selected radix to one of several other radices and vice versa. The radices may be binary, octal, hexadecimal or binary coded decimal entered on a keyboard 20 and the entered digits and the translated digits may show on display 72. The apparatus may be part of a computer arithmetic unit for performing the four rules of arithmetic. The operator selects the radix on keyboard 20 and enters the digits which are passed to data register 52 in parallel. If the data is entered in binary form it passes to the 2<SP>1</SP> terminal, if in octal to terminals 2<SP>3</SP>, 2<SP>2</SP>, 2<SP>1</SP>, and hexadecimal or BCD to all four terminals 2<SP>4</SP>-2<SP>1</SP>. If no radix is selected the keyboard treats the data as binary. The data is passed serially from the register on one of three lines 52-1, 52-3, 52-4 depending on whether the data is a 1, 3 or 4 bit code. The data register is controlled by a settable shift counter 40 itself receiving data from one of five registers 22-26 holding data in one of the four mentioned radices or an X (unspecified) radix received from keyboard 20. The counter 40 gives 1, 3 or 4 pulses on its output line 41, depending on the radix, which also pass to a four bit preset register 70 connected to a display register 71 and a display 72. The data from register 52 passes simultaneously to display register 71 whence it is displayed in groups of four, the number of data bits in each group depending on the code 1, 3 or 4, and to one of three 32 bit additional registers (80, 81, 82, Fig. 1B, not shown), one register for binary, octal or hexadecimal, one register for BCD, and one register for X, each register being connected to output 41 of counter 40. For an arithmetic operation data can be transferred from one of the three registers to a storage register (110, Fig. 1D, not shown) connected to a serial arithmetic unit for performing addition, subtraction, multiplication and division. Transfer is initiated by pressing a key and the data is ring shifted from register 80 to register 110 or from register 81 or 82 to register 80 then to register 110. Alternatively, to convert the data from one radix to another and display the converted data an appropriate radix key is pressed. If the data entered was binary, octal or hexadecimal it is present in binary form in register 80. To interconvert the data to another of these radices it is necessary only to regroup the bits using counter 40, see Fig. 3, where octal is grouped in three's starting from the most significant bit on the right and adding a zero to each group and hexadecimal is grouped in fours. To convert binary, octal, or hexadecimal to BCD or vice versa the contents of register 80 are counted downwardly and the contents of the BCD register 81 is counted upwardly or vice versa. This is claimed in British Patent No. 51806/72. In either case the data is displayed. The apparatus is controlled by pulses from a crystal oscillator.

Title: Production of hydrogen cyanide
IPC: C01C3/02
Filed: 1964-11-20
Abstract: Hydrogen cyanide is produced by reacting ammonia, natural gas, and air or oxygen in the vapour phase with hydrogen in an amount from 1.5 to 50, preferably 2-30, i.e. 10-25 mole per cent based on the natural gas over a platinum metal or platinum alloy catalyst, e.g. at 500-1300 DEG  C., preferably 900-1200 DEG  C., the mole ratio of ammonia to natural gas being 0.7:1 to 0.9:1 and that of natural gas to air 1:5 to 1:6.  Suitable catalysts are those containing platinum, or platinum in conjunction with another metal such as iridium, palladium or rhodium, e.g. 80-90% platinum to 20-10% rhodium gauze. The process may be carried out at any pressure.  Contact time may be 0.001 to 0.002 sec.

Title: Camera
IPC: G03B7/081
Filed: 1976-11-16
Abstract: 1520088 Photographic exposure control FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE] 16 Nov 1976 [23 Dec 1975] 47694/76 Heading G2A A camera has an automatic exposure control system in which (a) a pre-selected time automatically sets the diaphragm stop in dependence on subject brightness, and when a maximum or minimum stop is reached without an optimum exposure resulting, the pre-selected time is varied to a longer or shorter time while retaining the said maximum or minimum stop, or (b) a pre-selected diaphragm stop automatically sets the exposure time in dependence on subject brightness, and when a maximum or minimum exposure time is reached without an optimum exposure value resulting, the diaphragm stop is varied while retaining the said maximum or minimum exposure time. As shown, the film sensitivity is set by a potentiometer 6 which is connected to the input of a totalling amplifier 5. A signal corresponding to the light measured by a photo-cell 2 is also fed to amplifier 5. The exposure time or diaphragm value is set by a potentiometer 7 which is connected to the input of a second totalling amplifier 8, whose output is connected to amplifier 5. The output of amplifier 5 is connected to the inverting inputs of first and second sum-and-difference amplifiers 9 and 10, formed as operational amplifiers. The non- inverting inputs of these amplifiers are connected to potentiometers 11 and 12, on which are set the minimum and maximum diaphragm apertures or exposure times. The output of amplifier 9 is connected to the input of amplifier 8 through a diode 13, and the output of amplifier 10 similarly connected through a diode 14. The base of a transistor 17 is connected to a pulse generator 18, which is switched on by a switch 19 for manual operation only. When a fixed time is set, a switch 15 is left in the open position shown. Positive and negative signal voltages are produced respectively at the outputs of amplifiers 9 and 10. The output signal of amplifier 8 passes to a shutter time control circuit 20 to effect a shutter release and to an indicator device 31 comprising an array of luminous diodes. If, however, amplifier 5 calculates an output signal corresponding to an aperture value less than the set minimum, a negative signal passes through diode 13 to amplifier 8. If the value is greater, then a positive signal passes through diode 14 to amplifier 8. This correction signal is superimposed with the signal derived from the set time, which combined signal is passed to the amplifier 5, so making the time shorter or longer, as required. If a fixed aperture is set, switch 15 is changed over to the left, when it short circuits diode 13. If manual operation is required, switch 15 is changed over to the right, or switch 19 is closed to make transistor 17 conductive by means of pulses from generator 18. The pre-set time and diaphragm values now both show on the indicator.

A waterless gasholder comprising a casing 1 and piston 3 has an oil seal between the casing and piston, a basin 12 receiving oil leaking from oil seal basins 10, 10<SP>1</SP> and a pump 17 returning the leaked oil to a reservoir 7 connected to the basin 10. Excess oil passes, due to differences in pressure, from the basin 12 to a basin 15 communicating with the pump 17, the drive of the pump being derived from a drum 21 having a wire rope 22 wound on it, one end of the rope being connected to a roof truss at the top of the casing. The other end of the rope may be connected to a drum mounted on the roof truss, Fig. 1 (not shown). Means are provided, keeping the wire rope under tension such that any movement of the piston causes the drum 21 to rotate, thus operating the pump 17. Three or more such drums 21 and pumps 17 may be mounted on the piston to keep the piston substantially level. In a further embodiment, Fig. 3 (not shown), the drum 21 is substantially longer, the ends of the rope being connected to the drum 21 and the roof truss.

Title: Circuit arrangement for dial pulse receiving facilities in a telephone exchange system
IPC: H01M8/24
Filed: 1964-11-27
Abstract: 1,065,540. V.F. tone receivers. STANDARD TELEPHONES & CABLES Ltd. Nov. 27, 1964 [Dec. 4, 1963], No. 48251/64. Headings H4K and H4R. A circuit for receiving voice frequency signals from a subscriber's set Tln, at an exchange comprises a link VS which is seized for the call and which is connected via a switching network RKF to a register Reg. The register includes a hybrid G connected on its two-wire side to the link VS via the switching network so that, when the register is seized at the commencement of a call, dial tone is fed from generator WG through the conductive gate circuit T, and hybrid G to the subscriber Tln. The subscriber then operates the number sender to transmit, e.g. 2 x (one out of four), tone signals over the line via the link circuit and hybrid G to the voice frequency receivers Ton E, which are equipped with voice immunity circuits. The reception of valid signals at the v.f. tone receiver causes the gate T to be blocked via the " and " gate U and switches off the dial pulse generator WG. The decoded tone signals are also fed into a store Sp and the store keeps gate T blocked until the digits therein have been used or transmitted elsewhere. If then no further tone signals are received during a predetermined time, gate T is unblocked and the calling subscriber is connected to the forwardly extending line La via the register. After a further time delay the register is switched off normally. The receiver for the 2 x (one out of four) tones, Fig. 2 (not shown), includes " or " gates (01 and 02) to supervise the signalling and an " and " gate (U) to supply the signal to the operate gate (T). The hybrid transformer circuit and diode gating circuit is also described, Fig. 3 (not shown).

Abstract: 1495964 Flaw detection COMBUSTION ENG Inc 11 Nov 1974 [12 Nov 1973] 48719/74 Heading G1N Apparatus for inspecting tubes, for example in a steam generator, with a view to detecting flaws and identifying their position, both longitudinal and angular, comprises a plurality of probes united in a group for movement within a tube, each probe being capable of detecting a different flaw indicating characteristic of the tube. An elongate drawing member is connected to the group to propel the group through the tube and to control the angular orientation thereof, the drawing member being biased so as to have a tendency to roll up to a coil. As described a probe train 100 comprises an eddy current probe 110 and a film cassette probe 36 which are non-rotatably connected together and to either or both of cables 48, 50 which by virtue of their natural bias to coil maintain the probe train 100 in its desired orientation. The eddy current probe comprises coil pairs 112a,b, 114a,b, 116a,b supported within grooves of varying depth in bobbins 118, 120, 122 fixidly mounted on tubular member 124. Different sectors of coil in each coil pair are in close proximity to the tube wall, these sectors between them being sensitive through 360 degrees, the signals generated thereby via a bridge circuit allowing the orientation of a flaw to be ascertained. A picture of the flaw so detected may then be obtained by means of film cassette probe 36. A radiation source (32) Fig. 2 (not shown) is inserted in an adjacent tube and located adjacent the flaw, the γ radiation therefrom penetrating the tube walls to form an image on film (40) Fig. 14 (not shown) which may be shielded by lead (42) light opaque tape (44), and an envelope (46) of heat shrink material to shield against abuse, moisture and contamination.

Title: Electronic trunk junctor

Filed: 1974-11-12
Abstract: 1452386 Automatic exchange systems INTERNATIONAL STANDARD ELECTRIC CORP 12 Nov 1974 [16 Nov 1973] 48860/74 Heading H4K A junctor includes a ringing detection circuit and a trunk seizure circuit which are interconnected with a control circuit by electrooptical means. The junctor is used on a trunk connecting a public exchange with a PBX and includes a ringing detection circuit 1 for detecting ringing current from the public exchange and a trunk seizure circuit 4 which loops the trunk in response to a command from the control circuit, Fig. 5, and presents an effective inductance across the trunk wires 8, 9 when performing the trunking looping function. In operation negative cycles of an A.C. ringing current applied to wires AB are eliminated by Zener diode D1 and the positive cycles limited by Zener diode D1 are applied via transistor T1 to LED Do1, photo-transistor To2 being held operative by light emitted by LED Do2 (Fig. 5). LED Dol illluminates photo-transistor Tol of the control circuit to switch the output Q of bi-stable 10 to logic O, thereby indicating a calling condition to a central control which responds by applying logic O to wire 16, LEDs Do2 and Do3 therefore stop conducting to cause photo-transistors To2 and To3 to turn off, photo-transistor To2 blocking the ringing detector. The disabling of photo-transistor To3 enables transistor T2 to loop the trunk, the circuit 4 presenting an effective inductance across the wires 8, 9 (circuit 4 is generally referred to as a gyrator dipole). LEDs Do4 and Doy cause photo-transistor To4 and phototransistor Thy to conduct and thereby enables the trunk to be released should a power supply voltage drop occur due to an erroneous line seizure. LED Do5 makes it possible to dial directly into the PBX from the public network. For dialling out to the public network, the central control sends trunk seizure signals over wire 16 and trunk release signals over wire 17 alternately. Compensating for fine length.-It is said that circuit 4 acts as a virtual constant current device to cause the same current to flow through resistor R4 irrespective of the length of the trunk.
