Title: A fail-safe checking system
IPC: G08B29/04
Filed: 1965-09-30
Abstract: 1,124,746. Condition monitoring arrangement. SCULLY SIGNAL CO. Sept. 30, 1965 [Sept. 30, 1964], No. 41610/65. Heading G1A. A condition monitoring arrangement is capable of responding in different ways to an undesired value of the condition and to faults in the circuit or its components. A relay is made to pulsate and thus produce an audible signal or through contacts produce a flashing light, when the condition is either normal or abnormal, as desired, and is additionally arranged to fully pullup or drop out when a short or open circuit or vice versa occurs within the circuit. The circuit may be fed with A.C. or with D.C. with some form of interrupting switch changing periodically the voltage, the switch being either a relay contact or being cam operated. The sensor may be light or heat sensitive and may comprise-a lightsensitive rectifying transistor. A temperature sensitive resistor may be provided at a desired level in a liquid level monitoring arrangement and be cooled by the presence of the liquid to effect indication. The sensor may be in series or in parallel with the relay. Suitable relay constructions for pulsating are discussed, and operating currents are exemplified. The use of a change in pulse characteristic for monitoring purposes is also referred to, and means for quenching pulses in a pulsing transistor are described.

Title: Production of shaped bodies of carbonaceous material
IPC: C04B35/532
Filed: 1972-06-29
Abstract: 1395340 Forming carbon bodies from coated filler particles KERNFORSCHUNGSANLAGE JULICH GmbH 29 June 1972 [30 June 1971 2 July 1971] 42093/72 Divided out of 1395339 Heading C1A A shaped body of carbonaceous material is produced by (i) forming a non-dry green body without substantial application of pressure by moulding or shaping a sludge or paste consisting of binder coated carbonaceous particles with a small quantity of liquid, the surface of the particles being substantially completely covered by the binder, (ii) drying the green body to remove the liquid and (iii) carbonizing the green body. The sludge or paste may be prepared in or introduced into the mould, it may also be a kneadable mass which is self supporting when shaped and is shaped directly into the body. A precursor sludge may be used to form the desired sludge or paste by first drying the precursor and then introducing sufficient liquid into the dried material to give the desired sludge, before or after the shaping step. The liquid used may be one in which the binder is not or is only slightly soluble, or is swellable to form a paste which is then shaped. When the liquid is to be introduced into a mould containing the dried material, it may be introduced by exposing the material to the vapour of the liquid which then condenses on to the material, the liquid being one in which the binder is completely or partially soluble. The proportion of binder in the sludge or paste may be more than 25% by wt. The desired sludge or paste or the precursor sludge or paste may be obtained by forming a suspension of the carbonaceous particles in a solvent having a binder wholly or partially dissolved therein, and then introducing the suspension through a nozzle into a mixing chamber containing a liquid with which the solvent is miscible but in which the binder is insoluble or only sparingly soluble thereby causing deposition of the binder as a coating on the particles and recovering the so coated particles as a sludge or paste, e.g. by filtration or decantation. The mixture in the mixing chamber may be heated to facilitate the separation of the binder coated particles. The carbonaceous particles may be lamp black, powdered coke or graphite, and the binder may be pitch, tar, or synthetic resin, e.g. phenol-formaldehyde resin; graphite is the preferred filler. Methanol is specified as a solvent with water as the carrier liquid. The graphite may have a grain size of 0À06 mm.

Title: Actuators
IPC: F15B21/08
Filed: 1970-09-04
Abstract: 1357529 Fluid-operated actuator control systems ROTORK Ltd 27 Aug 1971 [4 Sept 1970 19 April 1971] 42352/70 and 9758/71 Heading F1P [Also in Divisions F2 and G1] An actuator comprises a linearly movable shaft 20 attached to the piston 22 of an hydraulic singleacting unit 11, solenoid valves 42, 49 for controlling fluid-flow to and from the working chamber 23 of unit 11, control means, Fig. 6, for controlling the solenoids 43, 50 of valves 42, 49, and selector means Figs.3, 4 and 5, (not shown, see division F2) for either causing the piston to be returned by spring means 35, 36 when the control circuit fails or is de-energized, or for holding the piston 22 in the position within the cylinder at which such failing or de-energization occurs. The low pressure side of piston 22 is open to the pressure of reservoir 24 in which a pump 14 operated by motor 13 is located. The fluid is pumped from reservoir 24 to the working chamber 23 and eventually, when required, returns to the reservoir. Expansion and contraction of the reservoir fluid is compensated for by a gas-filled bladder 25. The pump 40 pumps fluid from reservoir 24 to a line 41 and back to reservoir 24 via the normally open valve 42. If valve 42 is closed then the fluid is fed past the checkvalve 47 and thence to chamber 23 to move piston 22, the valve 49 being normally closed. If the valve 49 is opened, fluid can flow from chamber 23 back to reservoir 24, the piston be urged by the spring means. Clearly, if actuation of the solenoid 50 normally closes valve 49 then deenergization of the circuit stops solenoid operation to open valve 49 and permit the piston to be returned. An alternative fail-safe result can be obtained by arranging for valve 49 to be open during solenoid actuation so that de-energization closes the valve and thus holds the fluid in chamber 23 to keep the piston 22 in the position it attained at that time. Operation of the valves, by control of solenoids 43, is effected by the circuit of Fig. 6 in which the signals of a zero-set potentiometer 62 and a "required travel" potentiometer 60 are fed to a differential amplifier 64 for comparison with a feedback potentiometer 66. Amplifier feeds the required signal to control unit 55 which controls the solenoid-operated valves 42, 49 to produce the required length of piston stroke. The mechanism by which the position of the piston 22 is fed to the potentiometer is also described (See division G1).
