Title: Method of making a display apparatus comprising a light trans mitting unit and apparatus made thereby
IPC: G02B6/06
Filed: 1970-12-24
Abstract: 1380899 Display apparatus RANK ORGANISATION Ltd 22 Dec 1971 [24 Dec 1970] 61330/70 Heading G5C [Also in Division G2] A light transmitting unit comprises a block 10, one face 11 of which consists of a multiplicity of optic fibre ends 12a arranged in mutually spaced relation. From the opposite face of the block the fibres 12 are gathered together in a common ferrule 13 on the end of which light from a lamp 14 is focused by a mirror 15. Symbols may be constructed from groups of blocks 10, as in Fig. 2 (not shown). One method of manufacturing blocks 10 employs 20 spooled fibres 12 spaced 1 mm. apart which are interlaced by plastics strips for short portions 16 of their lengths, say 20mm., at intervals, say two feet, along the fibres 12. A portion 16 is placed on one end 17a of a belt 17 of felt which is at right angles to the fibres and impregnated with uncured epoxy resin, and the felt and fibres are then folded alternately over each other in such a way that portions 16 and felt 17 form a 30 layer sandwich. The loops 20, 21 are then cut, the resin cured, followed by cutting across the plane X-X, and the resulting faces 11 are ground and polished thus forming two units 10. Another method is to wind a continuous optical filament in a helix with resin impregnated spacers arranged at intervals around the periphery between successive layers in radial groups, In a further method a foaming agent, such as polyurethane foam, is applied to the fanned out ends of a bundle of fibres, which are then placed in an annular mould.

Title: Timer cirucit of an automatic telephone answering apparatus
IPC: H04M1/654
Filed: 1970-12-29
Abstract: 1335999 Substation equipment PIONEER ELECTRONIC CORP 29 Dec 1970 [29 Dec 1969] 61592/70 Headings H4R and R25  A telephone answering machine has a single timing circuit which starts timing when the machine is switched on in response to receipt of ringing signals but is reset to its initial state on receipt of message signals by a pulse generated in a circuit when the signal fulfils specific amplitude and duration requirements. The machine operates in the normal way with relay Y 1 operating to reproduce an answering message from an endless tape T1 and then by operation of a relay Y2 (not shown) the machine is prepared for recording the caller's message on tape T2. When relay Yl operates contact Y12 also operates and capacitor C6 in timer circuit 4 starts to discharge through resistor R2. If the discharge continued for about 10 secs. the voltage on capacitor C6 would allow transistor Tr4 to become conductive thus de-energizing relay Y 1 and returning the machine to a standby condition. Incoming signals on line 1 are recorded on tape T2 and also rectified at 6a causing transistor Tr1 to become conducting which causes Tr2 and Zener diode ZD to become non- conducting and capacitor C4 to discharge. A positive pulse is applied to the base of transistor Tr3 which conducts momentarily and allows capacitor C6 to become fully charged. During speech the capacitor C6 will be recharged frequently due to pauses in the incoming signal causing transistor Tr1 to be intermittently switched on and off. During silence or a continuous tone signal, e.g. dialling tone, capacitor C6 will discharge and the machine will be switched to standby after the set time has elapsed. If intermittent tones are likely to be received it is ensured that the delay circuit 6b does not have time to respond and allow more than the initial pulse to be generated so that the timing circuit is only reset once.

Abstract: 625,570. Distilling and crystallizing xylene. ANGLO-IRANIAN OIL CO., Ltd., BIRCH, S. F., FIDLER, F. A., and HARESNAPE, J. N. April 12, 1946, No. 11295. [Class 32] [Also in Group IV (b)] p-Xylene is obtained from an aromatic hydrocarbon mixture derived from coal tar or petroleum and boiling within 135-150‹ C. by separating by fractional distillation and/or low temperature filtration a fraction enriched in p-xylene, and a fraction enriched in o- and/or m-xylene, subjecting at least part of the latter to catalytic isomerization to convert part of the o- and/or m-xylene to p-xylene, and recovering p-xylene by fractional distillation and/or low temperature filtration. The aromatic fraction may be fractionated to give an overhead boiling up to 137‹ or 138‹ C. containing the ethyl benzene, a 138-139.5‹ C. fraction containing p-xylene and a residue of mainly o- and m-xylenes. The intermediate fraction is cooled to 0‹ to - 50‹ C. to crystallize p-xylene, and the residue passed with the o- and m-xylenes to the isomerization. Alternatively, ethyl benzene may be separated, the remaining xylenes cooled to - 40‹ to - 50‹ C. to crystallize p-xylene, and the mother liquors passed to the isomerization or an overhead containing ethyl benzene, p- and m-xylenes, an intermediate cut rich in m-xylene, and a residue containing o-xylene may be separated, the overhead cooled to crystallize p-xylene and the mother liquors fractionated to give ethyl benzene overhead, an intermediate containing m- and p-xylenes, and a residue concentrated in m-xylene, the intermediate cut being cooled to separate pxylene and the mother liquors fed with the first intermediate cut to the isomerization.

In a thermally-actuated safety cut-off device for gas burners comprising a bi-metallic strip 29 mounted on the valve casing 11 and engaging at its free end the operating stem 23 of a valve 22 in the gas supply to a burner nipple 10, also mounted on the casing 11. The valve is opened initially by the shorter arm of a horizontallypivoted manually-operated lever 36 engaging the strip and held in the raised position shown by the reaction pressure of the strip until released by deflection of the strip due to the heat of the burner flame. The lever 36 thereupon returns by gravity to a vertical position out of engagement with the strip so that should the burner flame become extinguished, the strip cools and the valve closes. One limb 28 of the U-shaped bimetallic strip 29 is secured to a lug 26 on the valve casing 11 and the other end engages the stem 23 directly or is bifurcated to engage a grooved member 33 on the stem. The poppet valve 22 may be replaced by a spring- loaded ball valve. The lever or latch 36 is pivoted on a forked member 34 mounted on a horizontally-extending lug 27. The valve cavity 13 is supplied through a narrow passage 15 adjusted by a transverse screw provided with a lock nut. The device is applied to a space heater and the casing 11 is provided with laterally extending trunnions which may be secured to the heater.

Title: Carbon Fibre
IPC: D01F9/32
Filed: 1979-03-14
Abstract: In a method of making carbon fibre, multifilament commercial heavy acrylic tow is initially heated under tension to remove crimp and provide initial stretch. The tow is then passed through a pre-heat zone below the critical temperature. The pre-heated tow is passed through an oxygenation zone of at least two stages, gradually being heated up to a temperature of 220-250 DEG C at which oxygen is taken up without degradation in a first stage, and the partly oxygenated tow being heated to a temperature of 260-300 DEG C in a second stage. The fibres are held under sufficient tension within the oxygenation zone to stretch them. The stretched and oxygenated fibres are thereafter carbonized at a temperature of 1050- 1600 DEG C under non-oxidizing conditions.
