Patent GB-846037-A (GB)
Title: Improvements relating to anti-icing systems
Inventor: DAVIS JOHN HOWARD
IPC: B64D15/04
Filed: 1958-01-03
Abstract: 846,037. Aerial housings. MARSTON EXCELSIOR Ltd. Dec. 23, 1958 [Jan. 3, 1958; March 31, 1958], Nos. 306/58 and 10820/58. Class 40(7). [Also in Group VIII] A radome having skin and core layers is provided with heating passages in the core layer arranged so that the heating fluid circulating in the passages is in close proximity to the outer skin layer over a large part of its area. To do this the areas where the core and outer skin are in contact are reduced to relatively small size and may be little more than lines. This reduces the strength of the resulting radome considerably, particularly where the core material is not readily bondable . to the material of the outer skin. To overcome this difficulty according to the present invention an intermediate layer is provided of material which can easily be bonded to the skin and this layer is secured to the skin over a comparatively small area and to the core over a comparatively large area to effectively hold skin and core together. In practice the core layer may be composed of expanded nitrile rubber and it may be cut or moulded to the required shape or foamed in place. The skin layer is preferably a glass fibre reinforcement, in which case the intermediate layer may be Of knitted or woven glass cloth. Suitable adhesives for the intermediate layer are those of epoxy or phenolic type, a glycol-maleic anhydride polyester laminating resin could also be used. The heating channels are conveniently triangular in cross section with their maximum width adjacent the outer wall. It is usual to provide an inner wall skin layer and the apices of the triangular heating channels may reach through the core to the inner skin or they may only reach to an intermediate level in the core. Fig. 3 shows a section through a radome wall in which the triangular heating channels 4 reach right through to the inner skin 2 and divide up the expanded core layer 3 into separate triangular sections. The outer skin 1 is in close proximity to the heating channels over a large part of its area. It has the intermediate layer 5 attached to it along the lines between the heating channel edges. The necessary strength of adhesion between the intermediate layer and the core is achieved by attaching them together over the centre channelled face of the core. Fig. 3 also shows the optional use of reinforcing strips 6 of approximate U-section bonded to the outer skin and to the intermediate layer adjacent the outer skin. Fig. 4 shows another embodiment in which the core 3 is made up of a number of separate trapezium cross-sectioned units. Each unit is wrapped in a separate intermediate layer portion 5 which overlaps as shown against the inner skin and is attached to both inner and outer skins where it is in contact with them. The heating channels 4 are triangular in section as before.

Abstract: 1,023,834. Controlling steam generators. SULZER FRERES S.A. Jan. 2, 1963 [Feb. 6, 1962], No. 318/63. Heading F4A. [Also in Division G3] A forced-through flow steam generator 1 and a superheater 2 supplies a turbine 3 driving an electrical generator 4. The working medium flows from the turbine through a condenser 5 and pump 6 to a preheater 7 and thence to a cold water reservoir 8. Water then passes through a pump or valve 9 and preheaters 10, 11, 12 to a hot water reservoir 13 from where it is pumped to generator 1. The preheaters are supplied with steam bled from the turbine. The flow of water to the preheaters 10, 11, 12 is controlled by the pump 9 (or a valve) actuated by a controller 26 which receives a signal from a controller 30 proportional to the difference in levels in the two reservoirs and a signal proportional to a plant balance magnitude such as steam pressure at 25, turbine speed or generated voltage or frequency. The controller 26 provides a P.I. control in respect of the signal from 30 and a PD control in respect of the signal from 25. The controllers 30 and 25 also act on a control 24 such as the generator burners. A controller 29 responsive to the sum of the liquid levels in the reservoirs acts through an integral controller 31 on a feed water pump 20.

Abstract: 775,506. Coating by vapour deposition. CORNING GLASS WORKS. Jan. 5. 1955, No. 345/55. Class 82(2) An elongated body, e.g. ceramic or glass rod or tube, is coated as it progressively travels from one point to another along a line of travel parallel to its length, by passing through an elongated space closely confining such body, introducing streams of vaporous coating material into the space from an external source, and causing the streams to converge on the body as they advance through an initial portion of the space and then to pass along the body as it travels through the space. As shown, glass tubing 12 issuing from an updown machine 10 is passed through a passage 27, into the input end. of which issue vapour streams, e.g. of tin oxide, from an annular row of apertures 25. The vapours impinge against the conical wall 26 of the said passage and are thus forced to converge on the tubing 12 as it passes therethrough, undeposited vapour passing to an exhaust system via the annual row of apertures 43. The coating resistance per unit length may be continuously measured by bridging a length of the tubing (or rod) with electrically conductive rollers included in a circuit with a current source and meter, whereby manual or automatic adjustments of vapour concentrations may be effected to obtain desired coating thicknesses. U.S.A. Specification 1,635,184 is re- (erred to.

Abstract: 1,203,651. Milling machine for chamfering rods and tubes. D. W. R. WALKER. 4 April, 1968 [5 Jan., 1967], No. 644/67. Heading B3K. Apparatus for pointing or chamfering the end of a cylindrical workpiece, e.g. a rod or tube, comprises a rotary cutting head driven about its own axis and mounted so as to swing bodily in a conical path the apex of which lies on the axis of the workpiece. The cutter, e.g. 11, Fig. 1 or 73, Fig. 6, may be directly driven by an electric or pneumatic motor 10, 72, or by flexible drive (Fig. 3, not shown). The cutter motor 10 is resiliently mounted by means of a rubber ring 17 which provides a biasing force urging the cutter against a workpiece located by a guide bush 24. In a further embodiment adapted to chamfer the internal end portions of tubes (Fig. 5, not shown) a rotating eccentric weight (61) biases the cutter against the tube end. In each embodiment in which the cutter is biased against the workpiece the resultant frictional effect may be utilized to feed the cutter around the workpiece. In the embodiment of Fig. 6, the cutter 73 is moved in a fixed and predetermined conical path by the crank mechanism 85, 86, 87 driven by a motor 75. In a similar embodiment (Fig. 4, not shown), the drive motor for the crank mechanism is mounted stationarily and drives an eccentric universal bearing (54) in which is supported one end of a rigid shaft (52) attached at its other end to and coaxially with the cutter drive motor (48).

Title: Improvements in travelling cranes
IPC: B66C13/00
Filed: 1921-01-06
Abstract: 156,661. Fitch, B. F. April 24, 1919, [Convention date]. Overhead travellers.-A travelling crane of the bridge type is fitted with a turntable so that the load can be moved angularly in addition to being hoisted and traversed. In the form illustrated in plan in Fig. 1 and in side elevation in Fig. 2, the skeleton rectangular bridge is supported by four pairs of running wheels engaging the I-beam tracks 10, and is traversed by two pairs of these wheels being driven by spur gearing from a common shaft 30 actuated by a hand chain wheel 35. An I-beam turntable track 40 is carried by the bridge and is engaged by pairs of rollers projecting upwards from a. diagonally-trussed rectangular frame carrying the hoisting and rotating mechanism. One pair of rollers is connected by spur gearing to a shaft operated by a second hand chain wheel 63 for rotating this lower frame round the turntable track. Hoisting-mechanism may be embodied in the apparatus, the form illustrated being adapted to raise transferable truck bodies by means of four ropes attached near the corners of the body. The four ropes are wound on two drums 76 operated simultaneously from a motor 87 through worm and spur gearing. An alternative hand-gear for raising the load comprises hand chain wheels 101 at opposite ends of a shaft 100 connected to the motor shaft through chain gearing 104 and a clutch 107. In a modified construction, which allows a limited angular rotation instead of a complete revolution of the load, the turntable track is formed by extending the four ends of the frame members 21 of the bridge to form overhanging curved tracks, which are engaged by the wheels of the lower frame. This construction reduces the depth of the apparatus and permits lower bridge tracks to be used.

Title: Gyroscope with brushless dc motor
IPC: H02K11/00
Filed: 1975-01-08
Abstract: 1492682 Electric motors; control of brushless motors CROUZET 8 Jan 1975 [15 Jan 1974] 730/75 Headings H2A and H2J [Also in Division G3] A gyroscope includes a brushless D.C. motor having an external toroidal permanent magnet rotor 1 and stator poles 2-2<SP>1</SP> carrying windings 8-8<SP>1</SP> (coil L1 in Figure 4), whose commutation is controlled by a rotor position sensor 3 consisting of a coil (L2 in Fig. 4) mounted on a saturable magnetic core responsive to the rotor field to vary the coil impedance as the rotor rotates. The coil (6) of the sensor is mounted on a ferrite pot (5) coupled to a ferrite magnet (7) and to the rotor 1 by silicon sheet metal strips (4, 4<SP>1</SP>), Fig. 3 (not shown). The coil L2 forms part of a multivibrator including transistors T3, T4 and the coil L1 is controlled by a transistor T1 whose switching instant is determined by the multivibrator, which controls transistor T1 through a circuit including a transistor T2, potentiometer P1 and a capacitor 33nF. Coil L2 generates negative peak voltages which are detected by diode D1 and integrated by the capacitor 33nF to form a voltage across the potentiometer P1, whose tapping is adjustable to regulate the switching instant of transistor T1. The voltage across capacitor 33nF is also dependent on the output of a voltage regulator consisting of transistors T5, T6, which are controlled by a transistor T7 to produce a high (10V) or low (4V) output voltage according to whether transistor T7 is conductive or non- conductive. The latter conditions are determined by the motor speed which is dependent on the back EMF of coil L1 detected by circuit components D4, P2, R(220) and C(25), the arrangement being such that, if the speed exceeds a value set by the Zener diode connecting members P2, T7, the transistor T7 becomes non-conducting to cause a reduction of the voltage across capacitor 33nF and hence a reduction of the ON-time of transistor T1 (down to zero depending on the setting of potentiometer P1). Protection against excess motor temperature may be provided by placing the sensor in contact with the windings 8, 8<SP>1</SP> and choosing the ferrite pot (5) such that the Curie point of the magnetic circuit of the sensor is relatively low (e.g. 100 to 150 C), whereby the multivibrator cannot switch on the transistor T1 when the motor temperature exceeds the value chosen in the aforementioned range.

Abstract: 606,232. Jetties; foundations. WETS, C., and PADUART, A. Jan. 11, 1946, No. 999. Convention date, July 4, 1945. [Class 68 (ii)] A jetty or like structure intended to sustain shocks, comprises a framework with non-rigid joints composed of parallelepipeds in contact formed by prefabricated concrete elements which are stayed and made into a stable structure by metallic tie-rods placed along the diagonals of the parallelepipeds and/or along the projections of these diagonals upon some of the faces, the tie-rods having a working tension sufficient to prevent play or movement, and the dimensions of the elements and the tierods being such that in case of shock the tierods break first. In the form shown, vertical, longitudinal and transverse reinforced concrete members 1, 2, 3 respectively are connected by high-strength steel, tensioned tierods 5, 5<SP>1</SP> protected against corrosion, which arc placed along the diagonals of the parallelepipeds and pass through oblique holes in and are anchored to extensions on certain of the concrete elements or joint blocks 4, Fig. 1, which engage with the concrete elements in such a way as to prevent their separation through lateral sliding. The surfaces of contact between the elements 1, 2, 3 and the blocks 4 may be convex or otherwise modified to increase the possible deformation of the structure under shock. Some of the elements may be connected and reinforced by pretensioned tie-rods 12 when engaging joints are unnecessary. The forces to which the jetty is subjected are transferred to the joints 4 by means of wood fenders 13, and produce tensions in the tie-rods 5, 5<SP>1</SP> and compressions in the concrete elements. The framework rests on wood or concrete foundation piles. The lower blocks 4<SP>1</SP> are adjusted thereon by wedges, and a surrounding concrete block 15 is cast in situ embedding reinforcements projecting from the pile and the block 41.

Abstract: PURPOSE:To improve reliability, by setting an allowance range of oil pressure and an oil level, while finding an operation zone of the oil pressure and the oil level from this allowable range and the detected temperature as a function value for comparison and, when something trouble is detected, varying temperature inside a pressure oil tank. CONSTITUTION:A temperature detector 9, an oil level detector 10 and a pressure detector 11 are all installed in a pressure oil tank 4, and each output out of these detectors 9-11 is inputted into an operation controller 12, while a heating device 13 and a cooling device 14 are installed in an oil collecting tank 2. An oil pressure-oil level allowable range in consideration of a temperature characteristic, where any drawbacks on a turbine operation controlling system are not produced, is determined, and with this allowable range and the temperature detected all the time, an oil pressure-oil level operation zone is found as a function value for comparison and, if something trouble is detected, temperature inside the pressure oil tank 4 is altered whereby an oil level inside the pressure oil tank 4 is controlled. With this constitution, the operation zone of oil pressure and an oil level in side the pressure oil tank 4, where any drawbacks on the turbine controlling system are not produced, is maintainable all the time, thus reliability is improved.
