Title: Thermal protection circuit for electric apparatus
Inventor: FARROW VICTOR FRANCIS
IPC: H02H5/04
Filed: 1965-05-21
Abstract: 1,044,498. Transistor switching circuits. THORN PARSONS CO. Ltd. May 21, 1965, No. 21687/65. Heading H3T. [Also in Division H2] A protective arrangement comprises a relay having contacts RLA-1 controlling the supply to a protected apparatus, a thyratron or thyristor TH1 in series with the relay winding   RLA/2, a temperature responsive resistor R3 2 associated with the apparatus and connected in a bridge circuit including zener diodes MR1, MR2, and an amplifier, e.g. a transistor VT1, connected across the output terminals of the bridge and controlling the device TH1. On one half cycle the zener diodes conduct freely and the bridge circuit is inoperative, but on the alternate half cycles the diodes are reverse biased and conduct with a constant voltage drop across each diode. Under normal conditions the balance of the bridge is such that the transistor VT1 conducts on the alternate half cycles and causes the thyristor TH1 to conduct, the relay being energized. When the temperature of the apparatus, e.g. a motor, becomes excessive, the resistance of the resistor R3 reaches a value such that transistor VT1 is cut off and the relay is de-energized. The relay may be provided with contacts RLA-2, which when the relay is de-energized, disconnect a resistor R5 and connect a resistor R4 so providing a large change in the balance of the bridge to ensure certainty of operation.

Title: Improvements in or relating to room heating or cooling systems
IPC: E04B9/00
Filed: 1959-06-24
Abstract: 897,749. Suspended ceilings; ceiling panels. STRAMAX A.G. June 24, 1959 [June 24, 1958], No. 21705/59. Classes 20(4) and 87(1) [Also in Groups XIII and XXV] The plates 2 of a sub-ceiling, heated or cooled by the pipes 3 which they conceal, Figs. 2, 5, and which support them, are hung so that at least some of the plates may be tilted and then detached for removal. The plates shown in Figs. 1 and 2, e.g. of plaster of Paris, mortar or stucco, reinforced with fibre, are in the form of trays, each with a middle, grooved ridge 7, the bottom of the tray, and the ridge, being covered by an aluminium sheet 8 with tongues anchored in the plate 2 and the bottom of the tray and sheet 8 having perforations leading to glass wool 16 contained in the tray and covered by a sheet 23 of kraftpaper. The plates may be without perforations, glass wool and the sheet 23 and they may be of metal faced with a thin, plaster layer or paint. A channel 12, with slots 11 so that it can be held by pins 10 on the ridge 7, forms with the ridgegroove a socket for the pipe 3 which allows the tilting, indicated in Fig. 2, for removal of the channel and plate when necessary. Normally the tilting is prevented by the presence of keys 14, Fig. 1, in grooves 13 formed in two opposite sides of each plate. The pipes 3 are suspended .from the ceiling by arrangements, Fig. 3 (not shown), each including a bolt and nut so that the height of the pipe can be adjusted. The ridge 7 may be offset to one side of the middle line, Fig. 4 (not shown), and the resulting tendency to tilt is prevented by an adjustable stop secured to the ceiling or to the plate. In Fig. 5, a simple plate 2 has an offset ridge 7 and the natural tilt is prevented by a bent extension 29 of the sheet 8 which clasps an extra pipe 3<SP>1</SP>. When tilted as indicated, against the natural tilt, the channel 12 is exposed for removal of the plate as before. If the grip of the bend 29 is made strong enough the ridge 7 can be made central and the pipes 3 and 3<SP>1</SP> equally spaced. In a still further embodiment, Fig. 6 (not shown), the sheet 8 has a bent extension similar to that 29 of Fig. 5, but in this case the extension clasps the pipe 3 and the pivotable support of the plate 2 is separate from that pipe. A hook of adjustable height is secured to the ceiling and links with an eye incorporated in the plate. For removal after tilting, the plate is unhooked or the hook is unscrewed from its ceiling attachment. Reference has been directed by the Comptroller to Specifications 690,271, 690,279, 690,320, 690,327 and 744,931.

Title: Improvements in and relating to devices for protecting electrical transformers and other apparatus
IPC: H02H5/08
Filed: 1937-08-09
Abstract: 494,197. Electromagnetic and magnetic switches ; protective cut-out systems; transformers. BUCHOLZ, K. F. Aug. 9, 1937, No. 21835. Convention date, Aug. 8, 1936. [Class 38 (v)] [Also in Group XXXV] A protective device responsive to a fault which results in evolution of vapour or gas, particularly applicable to a transformer or other oil - insulated electrical apparatus, comprises two members influencing one another magnetically or electromagnetically, one of which is arranged within a casing and is subject to displacement under the influence of the evolution of gas or vapour which accompanies the fault, while the other is arranged outside the casing and is adapted to operate a switch or indicator when the first member is displaced. In one construction, Fig. 1, a float 3 carrying a permanent magnet 4 is placed in a casing 2 connected to the cover 1 of a transformer tank. Under normal conditions, the magnet 4 attracts an iron plate 5 arranged outside the casing, but when the level of the oil, and with it the float 3, drops due to the collection of gases in the casing 2, the plate 5 is pulled away by springs 6 and completes a circuit at 7. In a modification, the permanent magnet 4 is replaced by an electromagnet energized by a coil which may either be mounted on the float or arranged outside the casing. In another construction, the iron plate is carried by the float, and the permanent magnet is movably mounted outside the casing. In the construction shown in Fig. 6, the float 3 carries a coil 23 connected to a source of current, and movement of the float causes an induced current in an external coil 24 which is adapted to actuate an alarm device. Fig. 7 shows an arrangement responsive both to accumulation of gas and also to the flow of oil, comprising an oil-filled casing placed in a conduit connecting the transformer with the conservator vessel. Accumulation of gas in the connecting chamber 26 causes a float 3 carrying a permanent magnet 4 to fall and release a plate 5, which springs upwardly and opens a contact or actuates a latch 27. A pivoted plate 28 responsive to the flow of oil is connected to a magnet 29 which normally attracts an armature 31 adjustably mounted on a lever 33 pivoted at 32, and holds the lever against a stop 34. When, in consequence of the expansion of the oil and evolution of gas, the flow of liquid attains a certain rate, the magnet 29 is withdrawn from the armature 31, and the lever 33 is rocked by a weight 35 to close a circuit at 36. The armature may be arranged to be normally outside the sphere of influence of the magnet, the magnet being sufficiently near to the armature to attract it in the event of a fault. The invention may also be applied to the protection of fermentation vats from excessive accumulation of gases. Specification 470,966 is referred to.
