Title: Pulse-train forming circuits
IPC: H03B19/00
Filed: 1970-09-24
Abstract: 1308784 Transistor pulse circuits SIEMENS AG 24 Sept 1970 [25 Sept 1969] 45428/70 Heading H3T A pulse train forming circuit for producing separate output pulse trains having repetition rates which are suitable for the subsequent production of an even-numbered and an oddnumbered multiple of a given frequency f 0  comprises a pulse shaping stage IP, Fig. 1, a monostable stage MM, a bi-stable stage FF, AND gates G1, G2, an inverter U and amplifier stages V1 and V2 providing an output pulse train T (2f 0 ) (a, Fig. 3, not shown) of double the given frequency (f 0 ) and an output pulse train (c, Fig. 5, not shown) whose repetition frequency for pulses of one polarity is equal to the given frequency T(f 0 ) respectively in response to a sinusoidal input frequency 2f 0  that is double the given frequency. The pulse shaping circuit IP delays the input (b, Fig. 2, not shown) to the monostable stage MM with respect to the input (a, Fig. 2, not shown) applied to the bi-stable stage FF. The output T(f 0 ) (a, Fig. 4, not shown) from the bi-stable stage FF, which divides its input by two, prepares each of the AND gates G1, G2 before arrival of the pulses (b, Fig. 4, not shown) from the monostable stage MM at a frequency T(2f 0 ). The output pulse trains (c, Fig. 4, not shown) of frequency T(2f 0 ) from the gates G1, G2 are displaced from one another by the time which corresponds to the period (2f 0 ). The output pulses from the gate G1 are inverted (b, Fig. 5, not shown) by inverter U and combined with the pulse train (a, Fig. 5, not shown) from the gate G2 in amplifier V2 so that a pulse train of opposite polarity pulses (c, Fig. 5, not shown) is obtained at the output of the amplifier V2 suitable for the production of odd numbered multiples of the basic frequency (f 0 ). The output pulse train T(2f 0 ) (a, Fig. 3, not shown) from the amplifier V1 is suitable for the production of even numbered multiples of the basic frequency. In a transistor arrangement of Fig. 1, shown in Fig. 6, the pulse shaper IP is Ts1, Ts7, Ts13, the monostable stage MM is Ts2, Ts8, Ts9, the bi-stable stage FF is Ts11, Ts12, the AND gates G1 and G2 are Ts3, Ts5 and Ts4, Ts6 and the inverter U is Ts10. The input transistor Ts1 acts to clip and amplify the input sinusoidal signal. The output amplifiers include push-pull Class B output stages Ts14, Ts18 and Ts17, Ts20 including driven transistors Ts15, Ts19 and Ts16. The circuit can be of integrated circuit form.

Title: Process for adjusting the electrode distance in an electrolytic cell with flowing mercury cathode.
IPC: C25B15/04
Filed: 1966-10-12
Abstract: 1,167,001. Mercury cathode cells. FARBWERKE HOECHST A.G. Oct. 12, 1966 [Oct.12, 1965], No.45564/66. Heading C7B. In alkali metal chloride electrolytic cells with flowing mercury cathode, the electrode distance is adjusted by bringing the graphite anodes, singly or in groups, close to the cathode until the oscillations of current or voltage, which occur with a small electrode distance, have attained a predetermined amplitude, e.g. measured as derivative of the current by induction across an annular transformer or as derivative of the voltage by charging a capacitor. The anodes may then be readjusted to a distance corresponding to the desired cell voltage, or the electrode distance corresponding to the predetermined amplitude may be maintained.

Title: Semiconductor mass memories
IPC: G11C19/18
Filed: 1973-10-05
Abstract: 1412391 Integrated circuit memories HONEYWELL INFORMATION SYSTEMS Inc 5 Oct 1973 [21 Nov 1972 26 Dec 1972] 46721/73 Heading G4C [Also in Division H3] In integrated circuit storage module, comprises a common semi-conductor substrate carrying a plurality of storage circuits, Fig. 23, connected to common, address, data, control and clock bus lines 113, 115. Each storage circuit includes address matching logic 106 for comparing address signals received from bus 115 with an address unique to that storage circuit and semi-permanently stored therein after manu - facture of the module, and a shift register 112 for storing data. In addition, each storage circuit is provided with a disconnect control 120 which is selectively energized after manufacture of the module to disable or enable transfer circuits 118 connecting logic 106 and the shift register 112 to the bus lines 115, whereby storage circuits which are defective or redundant may be disconnected. Each storage circuit may also have a rupturable link F in its power supply conductors. After manufacture each module is tested to determine which storage circuits are serviceable. A unique address is assigned to a storage circuit by applying a voltage to selected contact pads P, Fig. 25, so as to cause avalanche electron injection in floating gate devices F1-F3 whereby the gates are charged and the assigned address is stored semi-permanently. Erasure of the address may be effected by X-ray or ultraviolet radiation. The stored address is compared with address signals A from the bus 115 by transistors Q1-Q3 forming an exclusive OR circuit. Floating gate devices may also be used to inhibit the transfer circuits 118 of storage circuits which are not required. Organization of store.-The smallest unit of data which is addressable in the store is a data block 62, Fig. 6, which may comprise for example 256 words of 36 bits each, and which is transferred to a higher speed cache memory wherein individual words of the block may be accessed. In the store described, modules are grouped together to form assemblies 68 on printed circuit cards the number of operable storage circuits in each assembly being equal to an integral power of 2 (e.g. 256). It is possible to arrange modules in pairs which together have an effective number of storage circuits equal to a power of 2, some of the addresses in the two modules overlapping. For example, a module having 651 operable circuits assigned addresses 0-650 may be paired with another module having 389 operable circuits assigned addresses 635-1023 giving a total of 1024 address with 635-650 being duplicated. In accessing the store a segment address is decoded, 64 to supply a block address to a group of assemblies forming a particular segment. The same block address is used to select one shift register storage circuit in each assembly 68 whereby the block is accessed serial by word and parallel by bit.

Title: Power interruption monitor with delay disconnecting and reconnecting means
IPC: H02H3/24
Filed: 1969-09-23
Abstract: 1,261,995. Protective arrangements. BENDIX CORP. 23 Sept., 1969 [30 Sept., 1968], No. 46814/69. Heading H2K. A protective arrangement is operative to switch off a load 21 a predetermined time after a power supply 1 has failed and to switch on the load a predetermined time after the power supply has been restored. As shown, the load 21 is connected in series with the contacts 22 of a relay having a coil 11 connected in series with a silicon controlled rectifier 10 and a transistor 12 across the power supply. On initial application of the supply, a capacitor 9 charges rapidly through a diode 8 and through a Zener diode 19 renders the transistor 12 conductive. A capacitor 3 charges at a controlled rate through a resistor 2 and after a delay reaches a voltage sufficient to cause a unijunction transistor 6 to produce a pulse which triggers the rectifier 10 into conduction. The relay is operated to close the contacts 22 and to close contacts 4 to discharge the capacitor 3. When the supply fails, the opening of the relay is delayed by the capacitor 9 discharging through the rectifier 10, coil 11 and transistor 12 until the voltage across this capacitor has fallen sufficiently for the Zener diode 19 to cut off so that the transistor 12 ceases to conduct.

Title: Improvements in or relating to gas chromatography
Inventor: SMITH JOHN FREDERICK
IPC: G01N30/12
Filed: 1962-12-12
Abstract: 1,055,091. Gas chromatography injector. NATURAL RUBBER PRODUCERS' RESEARCH ASSOCIATION. Dec. 6, 1963 [Dec. 12, 1962], No. 46868/62. Heading B1L. A method of introducing a sample for gas chromatography comprises injecting a liquid sample into a heated carrier gas stream whilst it is passing through a Venturi in a gassageway within a metal block which is maintained at a temperature above that of the column. The gas is then passed to a metal equilibrator tube which is in thermal contact with the block and with a heat sink operating at the temperature of the column. Thus all liquid is vaporized and the gas stream enters the column from the equilibrator at the column temperature. The metal block and heat sink may both be made of a high thermal conductivity material e.g. copper, copper alloy or aluminium. The heat sink may be constituted by the chromatography column or a metal block. The equilibrator tube may be lower thermal conductivity than the block e.g. stainless steel, and the tube surface may be at ambient temperature, thus ensuring a uniform temperature gradient along the tube. Alternatively the tube may be of high thermal conductivity e.g. copper, copper alloy or aluminium and the temperature gradient established by the dimensions of the tube and/or cooling the surface with a current of air. A heated brass block 1 has a passageway 2 in the form of a Venturi with a feeder passage 3 coming from a tube 4 having a serum cap 5 closing one end thereof. A by-pass 6 enables carrier gas from tube 7 to sweep all the sample out of tube 4. Secured to the block in good thermal contact is a stainless steel equilibrator tube 8 containing stainless steel gauze rings 9 which are supported by gauze discs 10. The outlet end of the stainless steel tube may be connected to one end of a thick-walled aluminium chromatography column which may be thermostatically controlled. The temperature difference between block and sink may be 10‹C. The vaporized sample is said to enter the column as a "square pulse".

Abstract: 1,167,365. Measuring temperature, electrically. GENERAL ELECTRIC CO. Oct.25, 1966 [Nov.26, 1965], No.47788/66. Heading G1N. Temperatures at predetermined depths in the oceans are measured by a plurality of thermistors disposed at predetermined intervals along a cable corresponding to the depths, the cable being suspended by one end from floating buoy, and signals corresponding to temperatures sensed are transmitted by radio to a receiver base. Each thermistor is successively connected, via leads of predetermined length, and a rotating switch to a Wheatstone bridge Fig. 2 (not shown). The otherwise logarithmic resistance/temperature characteristic of each thermistor is linearized by the provision of a resistor in parallel while a resistor in series with each thermistor shifts the characteristic to within the operating range of the read out device. The potential drop across a thermistor and its associated leads and calibrating resistors is compared in the bridge with that across a reference resistor and the reference resistor is automatically adjusted by a servo to rebalance the bridge. The voltage across the tapped portion of the reference resistor is thus proportional to the thermistor resistance and to the temperature sensed, and, is transmitted by radio to a distant receiver. As shown Fig.1 thermistors 7 are disposed along a cable 1 and are connected by a respective pair of conductors 6 to the measuring bridge and calibrating network on the buoy. The cable also includes a stainless steel rope member 2 wrapped with tar impregnated jute 3 to provide thermal insulation, a plurality of conductors 4 which may connect pressure transducers to the read out device, for accurately determining the depths, a heat conducting layer of aluminium tape 8, and an outer sheath 9 of polyethylene.

Abstract: 1448819 Screened cable UNITED KING- DOM ATOMIC ENERGY AUTHORITY 22 Oct 1973 [18 Oct 1972] 47939/72 Heading H1A A screened high-frequency cable comprises a braided wire shield 3 and a magnetic tape 20 of, for example, Mu-metal (Registered Trade Mark) 0À002 inches in thickness wound in a manner which does not result in an increase in diameter at the overlap 21. When the Mu-metal tape is used it should have previously been annealed to allow it to stretch by more than 10% without fracture. The cable may be completed by a further metal braided shield and an outer jacket, or the further metal braided shield may be followed by a second magnetic tape and a third metal braided shield. A process for applying the magnetic tape comprises advancing the cable through a rotating tubular die 1b while the tape 5 is led from spool 4 over guide rod 9, angularly adjusted for minimum friction to enter a slot (1c, Fig. 2, not shown) in the die, substantially tangential to the die bore, along one side face. The guide rod 9 is carried by arm 8 which is fixed to the die. The rate of advance of the cable is adjusted so that the tape is applied with an overlap 25% for example, and the tension on the tape is adjustable by the device comprising a spring 6 and nut 7 on a screw threaded part of die portion 1a. As the upper lap of tape engages the lower the lower layer is compressed radially inwards to a greater extent than the upper lap is stretched.

Abstract: 1,217,424. Feeding webs. VICTORYKIDDER Ltd. 9 Oct., 1969 [14 Oct., 1968], No. 48511/68. Heading B8R. A web feeding mechanism comprises an aircushion table 4 which supports a web reel 3 on its side, the passage of air from a pressure supply 11 to the table 4 being controlled by a valve 12 responsive to the position of a dancer roller 13 around which the web 2 passes on its way to a processing machine 1, air-loaded turner bars (14, Fig. 6, not shown) being provided to turn the plane of the web from the vertical, as it leaves the reel 3, to the horizontal. Should the tension in the web become too low the supply of air to the table is reduced so that the reel tends to fall back on the table thereby increasing the friction between the two, the rate of unwind of the reel thus being automatically reduced; conversely the friction between the reel and the table is reduced by an increase in the air supply when the web tension becomes too high, and thus the web tension tends to remain constant during the unwinding process. The air cushion may be provided by supplying air under pressure to a plurality of spring loaded valves in the table 4 (Figs. 4 and 5, not shown), or to an annular groove formed in the table surface (Figs. 13 and 14, not shown); alternatively, air may be supplied through a spindle 5 to the space between the reel and the table (Fig. 15, not shown). If a plurality of webs are to be fed to a processing machine the reels may be supported on separate tables arranged one above another (Figs. 7 and 8, not shown), or side-by-side (Figs. 9 and 10, not shown), the reels being loaded on to the tables by aircushion conveyers. The spindles 5 may be pneumatically actuated to locate the reel on the table (Figs. 2 and 12, not shown) if the mechanism is used for winding rather than unwinding.
