Title: Low-pass electrical filter circuits
IPC: H03H11/12
Filed: 1963-06-07
Abstract: 1,035,042. Transistor amplifying circuits. SPERRY RAND CORPORATION. June 7, 1963 [June 8, 1962], No. 22752/63. Heading H3T. A low-pass electrical filter circuit comprises an input terminal between which and an earth connection an input signal is applied and which is connected through a first resistor to an output terminal, and a high-gain phase-inverting low imput impedance amplifier having its input and output circuits coupled to the output terminal through first and second capacitors respectively. The values of the capacitors are such that the attenuation factor of the filter is a second order function of the frequency of the input signal and the attenuation rises with frequency for frequencies above the resonant frequency. As shown in Fig. 1, one input terminal 10 of the filter is connected through variable resistor R1 to one output terminal. The amplifier comprises a transistor common emitter stage T1 followed by a common collector stage T2, the input signal to the amplifier being applied through capacitor C1 and negative feedback being provided between the emitter of transistor T2 and lead 25 by capacitor C2 and between the base of transistor T1 and a tapping on the emitter impedance R3, R4 of transistor T2. In operation, the D.C. component of the input signal e 1  passes directly to output terminal 26 and the A.C. component passes to phase inverting amplifier T1, the current passing through capacitor C1 being directly proportional to the magnitude and frequency of the input signal. Due to the negative feedback over capacitor C2 and choice of values of the components the A.C. components appearing at the output of the filter are highly attenuated at frequencies above a predetermined frequency. The feedback signal through resistor R3 to input of transistor T1 serves to stabilize the amplifier and lower the input impedance.

Title: Improvements in the production of knock-stable motor fuels
IPC: C10G45/04
Filed: 1934-08-07
Abstract: Anti-knock motor fuels are obtained from middle oils by treating the middle oils at 400--430 DEG  C., with hydrogen in presence of hydrogenating catalysts.  Separating the products boiling below 100--125 DEG  C., from the products obtained, and subjecting the latter to a reforming and dehydrogenating heat treatment under pressure so that an anti-knock product poorer in hydrogen is obtained.  Sulphides prepared as described in Specification 379,335 are preferably used as the hydrogenating catalysts.  The reforming treatment is carried out at temperatures of 475--560 DEG  C., under 70--100 atms. pressure and for a period of 1--10 mins. and the octave number knock rating is raised from 50 to 65.  Middle oil produced by the destructive hydrogenation of German brown coal is passed with hydrogen under 200 atms. at 420 DEG  C., over a tungsten sulphide catalyst.  A product is obtained containing 60 per cent benzines and 40 per cent heavier oils which may be further converted or used as lamp and Diesel oils.  The fraction boiling below 125 DEG  C., is removed from the benzine which is then passed at 500--520 DEG  C., and under 80--100 atms. pressure through an externally heated coil the time of sojourn in the coil being 2--4 minutes.  The product obtained is cooled by direct contact with middle oils, (separated from high boiling compounds), condensed, and stripped.  The final product has an octave number of 65 and on mixing with the lighter fractions distilled off a benzine having an octave number of 68 is obtained.

Abstract: 854,700. Telephone cables. WESTERN ELECTRIC CQ. Inc. July 18, 1958 [July 19, 1957], No. 23130/58. Class 36 [Also in Group XXV] A low cross-talk telephone cable comprises a plurality of groups of wires bound together, the wires of each group having back-and-forth random twists so that the relative orientation of the wires in the resultant cable varies in a substantially non-repetitive manner throughout its length. Fig. 1 shows an arrangement for forming such a cable. Twenty-six twisted pairs are fed from supply stands 10 to each oscillating unit 14 to form groups 15 having back-and-forth random lays. The groups 15 are then directed to a stationary face-plate 16 and are twisted together by a take-up unit 17. Each unit 14 (Fig. 3) consists of a main member 22 supported in bearings 23 and carrying a face plate 27 and a forming die 31. The member 22 is driven by a D.C. motor 43, the direction of rotation of which is periodically reversed by a switch 56 in the armature circuit actuated by screws 57, 58 on the member 22. The motors of all units are commercially identical and connected to a common supply but due to inherent manufacturing differences the lay in each-group differs slightly thus ensuring non-repetitive relative orientation of the wires in the resultant cable.
