Title: Improvements in and relating to protective devices for alternating current electric distribution systems
IPC: H02H3/30
Filed: 1919-11-20
Abstract: 158,736. British Thomson-Houston Co., Ltd., and Trechman, H. K. Nov. 20, 1919. Protective arrangements.-In a balanced protective system of the Merz-Price type employing core balancing ring transformers at each end the three-phase cable and having each a three-legged core, as described in Specification 141,121, the secondary windings 3 on the inner core are connected in series with the secondary windings 4 on the outer core and the windings of the respective transformers are connected together by two pilot wires 5, 12 the current in which, on the occurrence of a fault to earth or a fault between phases, operates biassed relays 7, 8 and 10, 11, the connections being such that the capacity current in one pilot wire normally balances that in the other. In the arrangement shown, the common point of the windings 3, 4 of one transformer is connected with that of the other by the pilot wire 12, the circuit being through the restraining-windings 14 of the earthfault relays 7, 8 and through the operating-windings 13 of the relays 10, 11 for dealing with faults between phases. The free ends of the windings 4 are interconnected by the pilot wire 15 through the operating-coils 6 of relays 7, 8 and the restraining-windings 9 of the relays 10, 11. The restraining-windings are given a percentage bias. With earth faults in the section, the resulting unbalancing between the secondaries 4 causes a current flow through pilot wire 5 and coils 8 and 9, thereafter dividing (i) through pilot wire 12 and coils 13, 14 and (ii) through winding 3 back to winding 4 through pilot wire 15. Thus the whole of the unbalanced current passes through the operating coils 6 of relays 7, 8 and part only through their restraining coils so that relays 7, 8 operate to isolate the section. Part only of the current passes through the operating coils 13 of relays 10 and 11 and, consequently, these relays are unaffected. With fault between phases of the section, however, the resulting unbalancing of the windings 3 causes current to flow in the pilot wire 12 through (i) the operating coils 13 of relays 10, 11 and (ii) through pilot wire 5 and coils 6, 9. The latter circuit, however, includes the reactance of winding 4 and the current therein does not affect the relays 7, 8 whereas the relays 10, 11 operate to isolate the system. A fault to earth outside the system causes no disturbance of balance and capacity current in the pilot wires may be limited by earthing resistances. A fault between phases outside the section again does not disturb the balance but may cause considerable capacity currents in the pilot wires 5, 12; as these currents, however, pass through the operating coils of one pair of relays and the restraining coils of the other pair, the percentage bias on the relays retains them inactive. In a modification, the relays 10, 11 may be dispensed with the connections being carried through as in Fig. 1 neglecting the relays 10, 11, and the pilot wire 12 being open circuited at the middle point.

Filed: 1953-10-20
Abstract: 735,614. Balloons. GENERAL MILLS, Inc. Oct. 20, 1953, No. 28919/53. Class 4. [Also in Group VIII] A method of forming a load-carrying balloon for sustained flights of sufficient size to support a payload and formed of non-extensible material, is characterized by forming spaced-apart seals across a length of tubular material to join the layers, and cutting across the seals to form a sealed envelope. The tubular material, preferably polyethylene or other thermoplastic, is drawn across a table 28, Fig. 2, and a hot wire 36 is used to sever the material and also to make a seal 32. Successive cuts produce sealed envelopes. A portion 50 of one seal is cut off, Fig. 7, when a message or instrument is to be inserted, the aperture then being resealed. One corner is removed, Fig. 11, for insertion of an inflating gas when the balloon is to ascend, the aperture 66 being resealed. The gas is preferably admitted to the extent where it provides buoyancy, but does not distend the envelope' until the balloon reaches a predetermined height.

Abstract: 1,253,982. Bunkering. COAL INDUSTRY (PATENTS) Ltd. 17 June, 1969 [18 June, 1968], No. 28931/68. Headings B8A and B8E. [Also in Division G3]  Solid particulate material is discharged into one part of a container and, when the material therein reaches a predetermined height, a detector causes the discharge means to advance along the container to feed another part of the container. In Fig. 1, particulate material, supplied on a conveyer 5 moving from right to left, is deflected by a transversely angled blade 6 into a container 1. Blade 6 is mounted on a trolley 8 which, when the level of material reaches a probe 12 carried by the trolley, is automatically moved to the left by an hydraulically operated winch to ensure a constant height of material along the container from which material is removed through hydraulically operated doors 2 and deposited on to a discharge conveyer 3. When the material reaches the level of probe 12, which may be resistive, capacitive or inductive, a relay (not shown) is operated to stop conveyer 5 and start movement of trolley 8 to the left. Time delay is provided to ensure a substantial movement of the trolley. If the level of the material is below the probe after this, the trolley moves back until it is not. Limit switches prevent excessive travel of trolley 8 and a centrifugal switch ensures that doors 2 are closed when conveyer 3 is stopped and only permitted to open again a predetermined time after conveyer 3 is re-started. Alternative, manual, control is provided for conveyer 5 and trolley 8

Title: Improvements relating to the control of the moisture content in clay
IPC: B28C1/22
Filed: 1961-08-15
Abstract: 952, 510. Automatic control of moisture content. WESTERN COUNTRIES BRICK CO. Ltd., and M. E. C. STEDHAM. Nov. 14, 1962 [Aug. 15, 1961], No. 29346/61. Heading G3R. The moisture content of clay, e.g. for brickmaking, is controlled by means responsive to the stiffness of the clay in addition to other means responsive to the moisture content itself. The moisture content is detected at or near the outlet of a mixer 11 at which tempering water is added, by measurement of electrical resistance or absorption of microwave energy or nuclear radiation; the signal is used to correct short-term variations. As shown, the clay is passed to an extruding machine 20, in the spacer section 25 of which the stiffness measurement is made. This may be by detecting the pressure on hydraulic fluid contained in a diaphragmed capsule in the path of the moving clay, by strain gauges which detect the deflection of probes, or by measuring the torque or current of the motor 22 driving the extrusion machine. The stiffness signal is arranged to correct for long-term variations, e.g. those due to changes in the basic clay. As shown, the signals are converted to pneumatic form, the moisture signal being pneumatically or electrically filtered to remove mixer paddle or other "noise", and applied to a controller 29 operating a valve 16 in the water supply. Both the controller 29 and a transducer/controller 31 in the stiffness signal circuit produce a pneumatic output signal which includes a term proportional to the deviation of the input signal from a referance value and also a term which is a time integral function of this deviation. Mention is made also of a possible differential function. The single valve 16 may be replaced by separate valves for each error signal, in the same or separate water supplies, or it may be a single valve responsive to separate signals. The invention may also be used when the clay is not extruded, the stiffness then being measured by the penetration of a probe into a column of the clay. In the Provisional Specifica- - tion electrical means may replace the pneumatic features shown.
