Filed: 1976-04-06
Abstract: 1515246 Carbon fibres TOHO BESLON CO Ltd 6 April 1976 [8 April 1975] 13813/76 Heading C1A Carbon fibres are produced by treating acrylonitrile polymer fibres containing at least 90% by weight of acrylonitrile at 200-300C in an oxidising atmosphere while allowing the fibres to shrink 40-70% of the free shrinkage of the fibres determined under a load of 1 mg/d under the same conditions, carbonising the oxidised fibres at 500-1,000C in a non-oxidising atmosphere while allowing the fibres to shrink by 40-70% of the free shrinkage of the pre-oxidised fibres determined under a load of I mg/d and treated at 1,000C for 15 minutes and finally heat treating the carbonised fibres at constant length at up to 3,000C. The degree of shrinkage in both stages may be controlled by passing the fibres through various stages over a series of independently speed variable rollers. Precursor fibres may be a homopolymer of acrylonitrile or a copolymer thereof with an acrylate, methacrylate, thioacetate, acrylamide, N- methylol acrylamide, acrylic acid, methacrylic acid, ionyl sulphonic acid, allyl sulphonic acid, methallyl sulphonic acid or a sort of such acids. The oxidation treatment may be carried out in air or an O 2  containing gas until O content of the fibres becomes 5-15%. Carbonisation is typically carried out at 700-950C in an atmosphere of N 2  until C content of fibres becomes at least 75%. The heat treatment is suitably conducted at 1,000-2,000C for 30 seconds-30 minutes in a non-oxidising atmosphere.

Abstract: 353,961. Collision guards for road vehicles. HUNTER, F. J., 73, Cleveland Gardens, Barnes, London. May 9, 1930, No. 14243. [Class 103 (ii).] A life-guard for motor and like vehicles comprises bumper bars H6 extending transversely in front of the vehicle, an electric motor P1 started when one of the bars H6 contacts with an obstruction, and mechanism operated by the motor for unrolling a leather mat K5 from its housing K1 and extending it to receive the obstruction. The guard is secured to the vehicle by two vertical brackets Al, A2 each having two bearings B1, B2 through which passes a mild steel shaft C1 having its rotation limited by a pin and slot E5, Jl. The shaft carries sleeves D1 .. D4 in the case of the three upper sleeves, having pin-and-slot connections E1, E2, with the shaft to limit rotation of the sleeves while the lowest sleeve has a slotted engagement with a lip-sleeve D5. Projecting from the latter internally is a pin E3 which normally is kept in contact with a pin E4 on the shaft C1 by a spring G1 anchored to the end of the shaft and to the sleeve D5. The sleeves D5 on each shaft Cl are connected by a rod Z1. Attached to each of the sleeves D1 .. D4 are two steel links H4 connected to a bracket H5 bolted to each bumper bar H6, the latter being kept in its normal position by V-shaped springs X2, X3. The housing K1 is supported at the bottom of the brackets and has a slot K6 along its entire length through which the front edge of the mat K5 projects, the mat being rolled on a shaft K2 revolving on bearings in endplates K3. Auxiliary brackets A4, A5 support a cross-shaft M2 having right- and lefthand threaded portions, and are grooved to support spring steel runners P2, P4 attached to a wedgeshaped rubber strip K7 secured to the front edge of the mat. The bracket A4 also supports the electric motor P1. Fitted between the brackets A4, A5 is a lazytongs arrangement reinforced by cross-pieces of channel steel R4, the ends of the tongs being connected to pins N1, N2 on nuts M6, M8 on the shaft M2, a shaft M4 preventing rotation of the nuts. In the neutral position the strip K7 rests upon lips on the two sleeves D5 and a plunger switch S5 is held open by the mat. When any one of the bumpers bars meet an obstruction, the shafts C1 are turned and rotate the sleeves D5 through the pins E3, E4. The forward edge of the mat drops from the lip of the sleeve and the switch S5 is closed thus starting the motor which operates the shaft M2 and forces the nuts M6, M8 towards each other. The lazytongs is thus projected and causes the mat to shoot forwards to receive the obstruction. On the nuts reaching the centre of the shaft they contact with another plunger switch S4 which breaks the circuit and stops the motor. The mat is returned to its housing by a reverse switch.

In a colour TV receiver, a signal of lesser bandwidth is connected over a series inductance shunt capacitance low-pass filter (Fig. 1, not shown) to the base of a NPN transistor amplifier whose emitter receives a signal of greater bandwidth over a series resistance and whose collector develops an output summation signal applied to the base of a further transistor amplifier having a frequency dependent series capacitance resistance feedback path connecting the output of a potential divider energized by the collector to the base of the first transistor, so as to equalize the frequency response (Fig. 2, not shown). In a development (Fig. 3, not shown) (R-Y) and (B-Y) colour difference signals from synchronous demodulators are applied over LC low-pass filters to the bases of respective adding amplifying transistors whose emitters receive Y colour signals over shunt RC circuits to produce respectively R and B signals at the collectors, which are applied over voltage dividers to the control grids of screen grid tubes with series LR anode loads to produce corresponding amplified colour signals. Frequency response equalizing feedback signals are derived from the resistance fed screens and applied over capacitances to the transistor bases. A green colour signal is formed in a matrix network from the (R-Y) and (B-Y) signals at the emitters of the adding transistors, and the Y colour signal, and energizes a similar screen grid amplifier.
