IPC: H01B1/24
Filed: 1969-05-29
Abstract: 1,259,315. Anti-static synthetic fibres; bonded fibre and tufted fabrics; yarns. TEIJIN Ltd. 29 May, 1969 [4 June, 1968], No. 27369/69. Headings D1K, D1P, D1R and D1W. Synthetic fibres are rendered anti-static and electrically conducting by applying a coating of thickness 0.5 to 15 microns comprising a mixture of acrylonitrile-butadiene copolymer and a phenolic resin the weight ratio of copolymer to resin being 0.4:1 to 4:1, the mixture having sufficient finely divided silver and/or carbon dispersed therein to lower the resistivity of the fibre to less than 10<SP>9</SP> ohm./cm. The conductive material may be present in an amount of 70-90% or 10-60% based on the weight of the coating for silver and carbon respectively and the copolymer may contain from 28- 42% by weight of acrylonitrile. Anti-static materials may be formed from blends of non- conductive synthetic fibres containing less than 2% by weight of the conductive fibres. The fibres may be coated by immersion in a paste formed from the copolymer, phenolic resin and conductive material in a volatile organic solvent, followed by heating to set the coating. In an Example, an antistatic nylon monofil was plied with every third, sixth, ninth or twelvth needle yarn of crimped continuous filament nylon in making a tufted carpet. In a further example a monofilament of the fibre material was incorporated in a tow with polyvinyl chloride filaments and this tow was crimped and cut to staple fibre 76 mm. long. The crimped conductive fibre retained its conductivity to an adequate degree. This staple fibre (70 parts) was blended with polyproylene staple fibre (30 parts), made into a web and then into several non-woven carpets by the needle punch method.

Abstract: 1295221 Vehicle transmission-mechanism parking-brakes; positive detents NISSAN MOTOR CO Ltd 18 Jan 1971 [17 Jan 1970] 2336/71 Heading F2E The brake pawl 14 is urged into the braking position shown in Fig. 2 indirectly by a torsion spring 26 surrounding a rotary shaft 15 and acting between an anchor pin 24, Fig. 5, penetrating the shaft, and a cam member 16 rotatably mounted on the shaft. The cam member in turn engages by its lobe 28 an enlargement 22 on the pawl to hold it against the action of another torsion (release) spring 20 surrounding the pawlmounting pin 19. The brake is controlled for application and release by a manually-operated knob 40 and rod 37, Fig. 9, connected to rotate shaft 15 by rod 36 and lever 35; the shaft 15 is permitted to occupy certain positions only, by a " clickstop " device consisting of a lock plate 30, Fig. 5, with edge recesses, mounted on the shaft, and a spring-pressed captive ball (not shown) engageable with the recesses. Each position of the shaft corresponds with one of the functional states of an assembly comprising engine 41, transmission mechanism 42 and differential gear device 43, Fig. 9, as indicated by the legend PRND 21 above brake knob 40. In any position other than P (parking), e.g. " neutral " (N), Fig. 4, pawl 14 does not engage parking gear 12 because enlargement 22 on pawl 14 is in contact with the smaller-diameter part 44 of the cam member 16. Also, spring 26 is preloaded so that its action on cam member 16 (in the counter-clockwise direction in Figs. 1, 2 and 4) is such as to force an axial stop member 29, Fig. 5, on the cam member into contact with the head 25 of pin 24. However, if shaft 15 should be turned towards "parking" position when pawl 14 lies opposite a tooth 18 of parking gear 12, Fig. 1, lobe 28 on cam member 16 becomes caught under enlargement 22 on pawl 14 before shaft 15 reaches its final position. As rotation of shaft 15 is continued, head 25 of pin 24 leaves stop member 29, thereby loading spring 26 further. If, thereafter, output shaft 11 is rotated slightly, cam member 16 is able to rotate to the Fig. 2 position, snapping pawl 14 into position with its tooth 17 between two gear teeth. In alternative embodiments: the cam-shaft 15 is perpendicular to the output shaft 11 and the pawl-mounting pin 19 (Figs. 10 and 11, not shown); the pawl-mounting pin 19 is perpendicular to the output shaft 11 and cam-shaft 15 (Figs. 12 to 14, not shown), in which case the pawl 14 is radially tapered (for strength) with its greatest axial dimension surrounding the pin; the output shaft 11 is perpendicular to the cam-shaft and mounting pin (Figs. 15 and 16, not shown). To release pawl 15 from parking gear 12, shaft 15 is rotated in a clockwise direction as viewed in Fig. 2. This moves cam member 29 clockwise by anchor pin 24 (extending through shaft 15). Lobe 28 is thus moved out of engagement with enlargement 22; enlargement 22 now rests against the circular part 44 of cam member 16, as in Fig. 4.

Abstract: 1295250 Preparation of rubber latices O W BURKE Jnr 12 Dec 1969 60824/69 Headings C3G C3P and C3Q The invention comprises a process for making a latex of a high modecular weight polymer comprising the steps of (i) making a solution of the polymer or polymer composition in a substantially water-immiscible solvent which has a boiling point less than that of water at atmospheric pressure, or forming an azeotrope with water, having a boiling point less than that of water at atmospheric pressure (ii) adding water and an emulsifier to the solution and mixing to form an oil in water emulsion containing aqueous particles of precursor latex size (i.e. which will form a stable latex when relieved of their solvent content) (iii) providing a moving flow of gas comprising steam, the gaseous phase (iv) introducing the emulsion into the flow of steam and subjecting the mixed flow to decreasing pressure whilst keeping the temperature within the stability range of the latex, whereby the solvent evaporates and passes into the gaseous phase, and (v) separating the resulting latex particles from the gaseous phase. Solvents which may be used include toluene, a xylene, an ethyl benzene or cumene. Examples relate to the production of latices of butyl rubber, ethylene/propylene rubber, a butyl rubber/silica composition, butadiene/ styrene rubber grafted with vinyl pyridine, a cis-1,4-polybutadiene/silica composition, and a natural rubber/acrylonitrile-ethylene glycol dimethacrylate copolymer composition, by the above process. Apparatus is described in which the emulsion is introduced to a turbulent flow of steam through a corrugated plate type heat exchanger. The latex produced may be recycled through the same or another heat exchanger, to increase its solid content by evaporation of water. The solvent condensed from the separated gaseous phase is reused.

Abstract: 1297877 Facsimile transmission HITACHI Ltd 4 Feb 1970 [5 Feb 1969 14 Feb 1969] 5454/70 Headings H4F and H4P In a facsimile transmission system to reduce redundancy in the binary encoded run length signals, each run length signal is divided into blocks and only those blocks from the least significant up to and including the block containing the most significant 1-bit are transmitted, a 1 or 0 bit being added to each block to identify whether it pertains to a black or white run length. A store is provided to temporarily hold the signals if their rate of generation exceeds the transmission rate, dummy signals being added if the generation rate is less. In the embodiment (Fig. 2, not shown) the run length is encoded as a four-bit binary signal which is split into two blocks. A counter having stages C 1 , C 2  (block 1) and C 3 , C 4  (block 2) counts clock pulses a for the period of a run length at the end of which differentiation circuit T and delay circuit D 1  generate a read-out pulse transferring the counter state to register R 2 , R 3  and R 5 , R 6 . Register stages R 1  and R 5  are set with a 1 if a black run length and register stages R 4  and R 8  are set to 1 if C 1 , C 2  or C 3 , C 4  contain a 1-bit respectively, to indicate whether the signal to be transmitted is from R 1  to R 3  or R 1  to R 3  plus R 5  to R 8 . The setting of R 8  automatically sets to preceding R 4  stage. Delay circuit D 2  provides a clear signal to the counter.

Abstract: 1309735 Electric selective signalling R H JONES 4 June 1970 [18 June 1969] 30827/69 Heading G4H A number of multi-contact switches connected to a multi-wire common cable operate some or all of their contacts in a predetermined order to transmit an identifying sequence of signals to a control device to selectively switch for example electric lamps. In the arrangement shown in Fig. 2 a sequence of three signals is transmitted by pulsing two of, or all three of, the signal leads 1, 2 and 3 of the common cable by sequential closure of the contacts of a remote switch (not shown). Each pulse passes via resistors R1 to R6 to one gate lead 1, 2, 3 to selectively switch particular SCR's in an SCR chain. The whole sequence of three pulses opens a unique path through the chain to operate one of the lamp energizing relays LR1 to LR12. Each pulse resets a timing circuit, including capacitor C, which times out the SCR chain. Circuits RC1, RC2 cut off a voltage supply to the chain if more than one switch is operated so resulting in two of cable leads 1, 2, 3 being pulsed simultaneously.

The filter is of the kind, more particularly described in Specification 1,136,158, in which resonant regions 2 are defined by capacitative tuning screws 1 each of which provides a reactance equal and opposite to that afforded by the associated length of evanescent waveguide. The resonant regions 2 alternate with coupling regions 3 and the centre of the pass-band is determined by the transverse D.C. magnetic field applied to ferrimagnetic (e.g. ferrite) elements 4. These extend over the resonant regions and into the coupling regions. It is shown in the Specification that the effects of the ferrite loading on bandwidth are opposite to each other for the two regions whereby it is possible to obtain constant bandwidth over the tuning range by properly choosing the dimensions of the elements. These may consist of single crystals of ferrite. In an alternative construction, each resonant region contains elements made of single crystals and each coupling region elements made of polycrystalline material.

It is stated that the mean particle diameter D s  in ft, is given by an empirical relation: where V s , V a  are solid, air velocity respectively and # s  is solid density in lbs per cubic foot. In the velocity measuring device the input signal m(t) derived from the upstream electrode 2 is delayed in an adjustable device 8 by a period # the delayed signal being multiplied at 9 with that derived from the downstream electrode 3 and the product integrated at 10 and indicated at 11. It is stated that when the integrand which is a cross-correlation function is at its maximum value then the time delay # is equal to the transit time ¯ of a given disturbance in powder flow between the electrodes. Thus the powder velocity V s  = (#/#) may be calculated. It is stated that the calculation of the cross-correlation function may be carried out by a proprietary crosscorrelator or by a digital or analogue computer. In use the apparatus is calibrated with particles of several diameters and Fig.4 (not shown) illustrates a plurality of peaks in the crosscorrelation function each of which peaks represents a different range of diameters.
