Filed: 1966-09-27
Abstract: 1,106,857. Associative stores. SPERRY RAND CORPORATION. 27 Sept., 1966 [28 Sept., 1965], No. 43018/66. Heading G4C. [Also in Division H3] In a content addressable memory using strip conductors 17-22 in association with wires 11, 13, 15 coated with anisotropic magnetic thin film to define discrete magnetic storage locations, each wire 11 has a two-location-per-bit digit position 39, 40 and a two-location-per-bit flag position 41, 42, the digit values being interrogated by simultaneously pulsing one digit conductor 17, 18 and one of two reference strip conductors 19, 20, followed by simultaneously pulsing the other digit conductor and the other reference conductor. The coated wires have a circumferential easy axis of magnetization, and the flux at any magnetic storage location as represented by vectors 23-38 is rotated towards the hard axis in the left facing direction when the associated strip conductor is pulsed by a driver 43-47. As shown in digit and flag positions 39, 40, 41, 42, the direction of vectors 23, 24, 33, 36 represent a stored ONE while vectors 27, 30 in the reference position defined by strips 19, 20 represent a stored ZERO; this notation applying throughout the memory. To write a ONE in a digit position the strip 17 and the wire 11 are coincidently pulsed by respective currents I 1 , I 3 . Strip 18 and the wire 11 are then coincidently pulsed by respective currents I 2 , I 4  ; I 3  and I 4  being opposite in direction. To write a ZERO the order I 3 , I 4  is reversed. When a digit position is to be interrogated for the presence of a ONE, the pulse pattern of currents I 1 , I 2 , I 5 , I 6 , I 7 , I 8  shown in Fig. 2 is applied to the strips. Currents I 5 , I 6  are used to rotate the flux of the flag locations towards the hard direction so that switching of a flag position can be effected by current in the associated wire, the current arising if the digit stored is ZERO. The flag switching phase occurs during the transitional period when currents I 1  and I 7  terminate and I 2  and I 8  commence, the flux vectors 24, 30 of one digit location and one reference location restoring from the hard to the easy direction at the same time as the flux vectors 23, 27 of the other digit location and reference location rotate towards the hard direction. If the digit stored is ONE the induced voltages due to these rotated fluxes mutually cancel and no output is produced in wire 11. If on the other hand the digit stored is ZERO, the induced voltages augment one another and cause the associated flag location to switch to ZERO as denoted by vectors 33a, 36a. The order of currents I 1 , I 2 , I 7 , I 8  is changed for interrogating a ZERO, Fig. 3.

Abstract: 1420655 Tobacco filters ROTHMANS OF PALL MALL (AUSTRALIA) Ltd and LANTOR OF AUSTRALIA PTY Ltd 18 Sept 1973 [27 Sept 1972] 43692/73 Heading A2C [Also in Divisions D1 and D2] A tobacco smoke filter is produced from a bonded non-woven fabric comprising wool fibres, by folding the sheet about its longitudinal axis and compressing 1 - 1¢ inch length, 18-22 micron Merino wool may comprise 75-100% of the fibres the balance being cellulose acetate, cellulose, reconstituted cellulose, polyolefin, polyamide, polyethylene terephthalate or polyvinyl chloride-polyvinylacetate copolymer. The wool is scoured, carbonised, fully bleached by peroxide or perborate, optionally blended by carding and air laid to form a random fibre web. The web is passed through an aqueous dispersion of polyacrylate, acrylonitrile - butadiene copolymer or styrene-butadiene copolymer incorporating melamine-formaldehyde hardner to promote cross-linking. Excess polymer is removed and the web passed through a 250- 350‹F heating tunnel to dry the web and cure or cross-link the binder. The web is slit into 5 inch wide strips and each strip passes through the nip between heated ribbed rolls 6 to impart a quasicorrugation in longitudinal direction of the fabric. Pre-folder 8 then turns the edges of the strip upward and over towards the centre whilst the centre of the strip is raised. A cylindrical plug is then produced by trumpet 9 and heated condensing tube 10. The plug is then converted into wrapped filters in conventional apparatus. The wool filter may entirely replace the celluolse filter in a filtertipped cigarette (Fig. 2A, not shown), it may be sandwiched between the tobacco and the conventional filter (Fig. 2C, n.s.) or form the middle part of a three part filter (Fig. 2B, n.s.). The filters may also be used in pipes and cigarette holders.

Title: Circuit arrangement for the suppression of impulses
IPC: H04N9/455
Filed: 1965-10-15
Abstract: 1,099,439. Colour television; gating circuits. FERNSEH G.m.b.H. Oct. 15, 1965 [Oct. 15 1964], No. 43899/65. Headings H3T and H4F Relates to a circuit arrangement for the suppression of an impulse occurring during an interval of otherwise constant value in an electrical signal, e.g. a chrominance signal which in the demodulated condition contains periodically repetitive burst impulses in the horizontal blanking interval. The burst impulses are suppressed because they may have different amplitudes and polarities according to their phases prior to demodulation and thus when the clamp circuit in a colour television display comes into operation, which is during the burst impulses, the direct current component of the signal varies, i.e. the background brightness of the picture screen becomes dependent upon the phasing of the colour burst before demodulation. Although the phase of the colour burst is nominally constant it may vary due to chroma control adjustments. As shown, Fig. 1, the circuit arrangement comprises a capacitor 4, to which is applied the composite demodulated chrominance signal 12, Fig. 2, via a transistor 2, a resistor 5, clamp circuits 8 and 9, and an output terminal 13 at which there appears output signal 14, Fig. 2. The junction of capacitor 4 and resistor 5 is connected to earth during the front porch periods by means of clamp circuit 8 to which is applied pulses 22, Fig. 2, and the other terminal of resistor 5 which is connected to the base of transistor 3 is connected to earth during at least the interval in which the burst impulse appears by means of clamp circuit 9 to which is applied pulses 28, Fig. 2. The Specification discusses the fact that the resistor 5 should be given a high value so that practically no discharge of capacitor 4 is effected during the horizontal blanking interval, but not so high that the frequency response of the composite chrominance signal is markedly deteriorated since resistor 5 forms a low-pass filter with the stray capacitances of transistors 3 and 23. As a result of the effect of the two clamping stages the impulses 29 are thus suppressed, so that the composite chrominance signal shown by waveform 14 is fed out by means of load resistance 7 and output terminal 13. The Specification describes an arrangement of apparatus, Fig. 4, not shown, for indicating the phasing of chrominance signals by means of a vectorscope and for simultaneously displaying these chrominance signals by means of a colour television display unit, the demodulated burst impulses being suppressed.

Abstract: 1,125,724. Automatic speed control. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct.19, 1965 [Oct. 22, 1964], No.44213/65. Heading G3R. [Also in Division H2] The speed of a battery-fed motor 1 is regulated by a comparator circuit comprising bridge 4-7, a reference voltage being developed across diode 7, whilst the voltage at the junction of resistors 4, 5 varies with the motor voltage. The error voltage is applied to the base-emitter of n-p-n transistor 8 whose collector is directly connected to the base of p-n-p transistor 3 which is in series with the motor. Resistor 9 compensates for variations in the motor-load. A resistor, having a negative temperature co-efficient and associated with resistor 5, may provide temperature compensation. Alternatively, the diode 7 may be arranged to provide stabilisation against temperature variations. In another arrangement, the transistors 3 and 8 are of the n-p-n and p-n-p types respectively. A lamp in parallel with transistor 3 indicates the charge condition of the battery.

[Also in Division G3] A fluidic sensor comprises a first oscillator means 10 for generating pulsating fluidic signals of a frequency which is a function of the sensed characteristic, e.g. temperature, motion, pressure or humidity, a resonator means 11, a rectifier means 12 and an amplifier 13 which produces a differential pressure output. The oscillator (Fig. 2, not shown), has a sensing tube 15 which is placed in the medium to be sensed and two outputs 21, 22 through which the output flows in alternate oscillations in a known manner. The oscillation rate varies as the speed of sound which, for temperature sensing, is proportional to the square root of the temperature. The output signals pass down lines 31, 32 to beam type diodes 38, 40 (Fig. 3, not shown). Line 31 divides into lines 41, 42 of different lengths (and thus of different resonant amplitude characteristics) which change the relative amplitudes and cause relative phase shift between the signals (Fig. 5, not shown). The amplitudes of the respective output signals from the rectifiers 38, 40 are of different magnitude and vary as the frequency of the oscillator signals. The signals are filtered in units 58 (Fig. 4, not shown) and further amplified in the known amplifier 13. A differential pressure representing the temperature exists in lines 62, 63 and this pressure controls a retractive actuator 67.
