Abstract: 1,257,844. Pneumatically emptying containers; loading vehicles. J. H. ASKEW. 13 Feb., 1970 [8 Oct., 1969], No. 49483/60. Headings B8A and B8E. A container 2 is mounted on a lorry for the transportation of light-weight materials, e.g. wood shavings, and has on its inside a fan 5 to whose inlet these ducts 3a-3c are secured and at whose outlet is a two-way flap valve (20), Fig. 3 (not shown), mounted in a housing 6. To fill the container 2 the material is sucked in by the fan 5 through a flexible hose 10 and ducts 3 and blown into the container interior through a duct 7. In order to empty the container, the duct 3c is removed and flap valve (20) moved to block the entrance to duct 7 and open an outlet duct 9. Duct 3b may be removed at a later stage to permit removal of material in the centre of the container, and the hose 10 may be secured to the duct 9 so that the end 11 may be used for the discharge of material. The fan 5 may be driven from the gear-box of the lorry engine 13.

Abstract: 1326769 Coating with carbides W or Mo FULMER RESEARCH INSTITUTE Ltd 29 Sept 1971 [8 Oct 1970] 47981/70 Heading C7F [Also in Division C1] Tungsten and/or molybdenum hexafluoride benzyne, toluene or xylene and hydrogen react in the vapour phase at a temperature between 400 degrees and 1000‹C. to produce the respective carbides, the carbon/hydrogen ratio in the mixture being sufficiently low to ensure that no carbon is deposited during the reaction. The total hydrogen in the mixture both free and combined should not appreciably exceed that required for complete conversion of the metal hexafluoride into hydrogen fluoride if it is desired to produce the pure carbides. However, by varying the composition of the gas mixture e.g. using a total amount of free and combined hydrogen exceeding that required for complete conversion of the hexafluoride into HF, mixtures of the metal and the metal carbide may be produced. The process may be used for the vapour phase coating of metal substrates and of carbon fibres. In the case of coating mild and other steels, a sub-coating of nickel or cobalt (deposited electrolytically or chemically) is preferably produced on the steel prior to the vapour phase deposition of the carbide. A particular substrate may also be coated using a fluidized bed technique.

Abstract: 1329368 Automatic exchange systems SIEMENS AG 15 Oct 1971 [27 Oct 1970] 47975/71 Heading H4K In a digital transmission network comprising groups of exchanges that utilize different bit rates and modulation modes, tandem calls via an exchange group utilising a modulation mode different from that of the terminal groups are set up without the aid of modulation changers. As shown groups A and B use 2-4 Kb. PCM whereas group B uses 19À2 Kb. delta modulation. A connection from subscriber Alk to C1m is set up via tandem exchanges B1 and B4 over multiplex lines that incorporate bit rate changers GU, i.e. pulse stretchers and shorteners which may be monostables, that serve to match the different bit rates of the three groups but without any change of modulation at the interfaces between the groups. A connection between A1k and say B4n however requires a modulation changer MU. The latter has two appearances on exchange B1's switching network such that it is effectively in series with the transmission path between A1k and B4n. The switching networks may incorporate superhighways with channel stores being provided for time slot changing. The interexchange highways may comprise carrier radio or line transmission systems. Signalling data, e.g. dial signals must be converted so that a tandem exchange can interpret them correctly, appropriate converters may therefore be connected in parallel with the rate changers in each intergroup highway. A mobile subscriber nominally attached to one group, e.g. Co in group C, may be provided with a direct (radio or line) link to an exchange e.g. B4 in another group, this line being equipped with a bit rate changer but a modulation changer only being required if a call involving Co terminates in group B.

Abstract: 1343111 Slack adjusters GIRLING Ltd 19 April 1971 [3 April 1970] 15854/70 Heading F2E A brake slack adjuster comprises a nut and shaft having a reversible screw thread connection, i.e. a connection wherein relative axial movement of the nut and shaft produces a relative rotation whereby driving braking, means causes relative radial displacement between the nut and the shaft to avoid relative rotation of the two. An hydraulic brake, having opposed pads axially moving to clamp a disc, operated by opposed pistons 15, 16 and a floating caliper 19, a split or axially slit nut 25a, 25b engages a shaft 23. During the application of the brake, the shaft 23 is forced to the right with piston 16 by fluid pressure, and leftward movement of piston 15 causes a spring biased ball bearing 32 to move against a shoulder 33 on the nut 25a, 25b. Spring force urges the nut 25a, 25b leftward with the bearing 32 producing the adjustment. With the brake fully applied and during release of the brake, reverse movement of the nut 25a, 25b is avoided by the clamping action of a frusto-conical sleeve 26 forcing the nut against the shaft 23. Handbrake operation is through a cam 20 and dolly 22, forcing the shaft and thus the piston 15 leftward. Once again the sleeve 26 avoids relative movement between nut 25a, 25b and shaft 23. A Belleville washer 37 and pawl 34 engage ratchet teeth 35 in the sleeve 26 to avoid rotation of nut 25a, 25b due to vibration.

The vanes are biased into contact with the chamber walls as by a spring band or internal air pressure within the rotor. The heat exchanger outlet port is so located that the fluid volume defined by the vanes immediately on either side of the port at a given rotational point has a valve adapted to accept the same amount of fluid mass as entered the heat exchanger inlet port at the given rotational point. Moisture or ice particle catching means, Fig. 11, comprising baffles are mounted in an outlet duct to dehumidify the exhaust air and the inlet and outlet ducts may be interconnected and the collected moisture may be used to cool the heat exchanger fluid.

Abstract: 1348786 Measuring the length of moving vehicles; road traffic signalling apparatus PLESSEY CO Ltd 14 May 1971 [5 June 1970] 27406/70 Headings G4H and G4Q Apparatus for measuring the length of a moving vehicle comprises a first counter 14 the output of which is related to the speed of the vehicle, a second counter 12 the output of which is related to the length and speed of the vehicle and a circuit 28 responsive to the two outputs for determining the length of the vehicle. A pair of inductive loops A, B are arranged in the path of the vehicle so that when a vehicle enters the loop A, a detector 8 enables the second counter 12 to start counting clock pulses from a generator 16. When the vehicle leaves the loop A, the detector 8 stops the counter which therefore has a count proportional to the sum of the vehicle length and the length L 1 of the loop A divided by the vehicle velocity. When the vehicle enters the loop A, the first counter 14 also starts to count and is stopped by the combined outputs of the detector 8 and a detector 10 when the detector 10 senses the entry of the vehicle into the loop B. Hence the count in the counter 14 is proportional to the known distance L 1 + L3 divided by the vehicle velocity and a line 36 may provide a digital speed indication. From a knowledge of the frequencies of the clock pulses fed to the two counters, the length of the vehicle is calculated and compared with a stored critical length to provide an output on a line 32 or 34 depending on whether the measured length is above or below the critical length.
