Filed: 1970-06-29
Abstract: 1312829 Measuring fluid flow electrically SIEMENS AG 29 June 1970 [28 June 1969] 31465/70 Heading G1N In a fluid flow monitoring probe the probe face 2 is provided with one or more recesses e.g. trough shaped across the mouth(s) of which the fluid 3 being monitored flows and adjacent which are positioned an electrical sensor device 8 such as a semi-conductor thermistor or thermocouple and a thermal control means 4 for controlling the temperature of device 8. Where the fluid 3 being monitored is a coolant fluid of a power generator control means 4 are in the form of a heater wire and the wire and device 8 are potted in aluminium containing resin 6. The trough edges 7 are of such height that when the rate of flow of fluid 3 slows down a vapour film forms at the heat exchange surface 2 which film impairs heat exchange between sensor 8 and fluid 3 so that the temperature of sensor 8 rises and its electrical parameters alter with higher rates of flow the trough edges 7 produce a whirling of the fluid 3 and heat is extracted from the device 8. A positive temperature co-efficient registor 9 may be provided to reduce the heating voltage of heater 4 when the probe is not immersed i. e. prevents over heating. The recesses may be in the form of a honey comb like structure or a roughened structure and flow-hindering elements may be also provided.

Title: Improvements in the manufacture of lace on single thread lace-braiding machines
IPC: D04C3/00
Filed: 1920-11-09
Abstract: 162,635. Henkels, A. & E. April 26, 1920, [Convention date]. Braiding-machines.-To avoid the use of auxiliary threads to hold the web together during the drawing-off operation, which threads are subsequently cut out of the fabric and wasted, the braiding-threads are laid in places over fine springy steel wire d which extend from pillars b mounted on the centre plates a, to the braiding point, and are bent up as shown so that the free upper ends lie parallel to the mandrel k. Each wire d is mounted on a sleeve e which lies on the top of the pillar b when in action. The wires d and pillars b are provided only on the plates corresponding to the places where auxiliary threads would otherwise be required. On receiving thread crossings the corresponding wires are pushed up by rods h working inside the pillars under control of the pattern gear and are held above the bobbin threads on the overhanging arched end of a pillar c by a spring catch f. An inoperative wire is brought into operative position by a lever g acting under pattern control.

Title: Omnidirectional beacon antenna
IPC: G01S1/02
Filed: 1958-10-03
Abstract: 844,559. Aerials. STANDARD TELEPHONES & CABLES Ltd. Oct. 3, 1958 [Oct. 10, 1957], No. 31670/58. Addition to 772,120. Class 40(7). An aerial system suitable for use at a TACAN radio beacon station and capable of producing the required multilobed rotating radiation pattern is constructed with a view to maintaining an adequate depth of modulation up to high angles of elevation. This is done by reducing in length the rotating parasitic elements forming the pattern lobes as compared with similar elements in prior art aerial systems and by arranging the shortened elements in groups. The embodiment shown comprises a vertical central array of four cylindrical dipoles 7, 8, 9, and 10. These dipoles are coaxial with a central feeder system described in detail with reference to Fig. 2 (not shown) which supplies energy to them in the proportions 1:2:2:1 and with relative phase relationships -45 degrees: -30 degrees: + 30 degrees: -45 degrees. The array is stationary and is enclosed in a dielectric cylinder 2. Surrounding the cylinder 2 is the rotating part of the structure consisting of inner and outer dielectric cylinders 4 and 6, dielectric cap 23, and conductive counterpoise surface 24. The whole aerial system is mounted in a stationary dielectric radome 28 on a bottom support 29. The outer rotating cylinder 6 carries nine equally spaced groups of parasitic elements. The arrangement of elements in one group is shown in Fig. 3. For operation at a frequency of approximately 1,000 mc/s. the element 30 is 7 inches long and the elements 31 and 32 on either side of it 5 inches long. Above the element 30 is element 33 of length 4# inches and, to the side of this, element 34 seven inches long. Elements 31 and 32 are made of resistance wire and the remaining elements of copper wire. There is a single group of parasitic elements mounted on the inner cylinder 4 arranged as shown in Fig. 4. Here the elements 35 and 36 are each 6¢ inches long and the V-elements 37 and 38 which serve to increase the coupling between them have 3“ inch legs set at an angle of 60 degrees. The upper element 39 is 4¥ inches long and all the elements are of copper wire. The Specification gives full details of the positioning of the elements relative to each other and to the central array for the frequency mentioned. There is also described with reference to Fig. 5 (not shown) a suitable group of outer parasitic elements for use with a central array of seven vertically aligned kiconical radiators. An explanation of the theory involved is given, reference being made to the vector diagrams and curves of Figs. 6 to 11 (all not shown). The reason that short parasitic elements of the order of half a wavelength long are used is that these have definite centres of radiation which do not shift appreciably with any change of frequency. Further, short elements are easier to place to obtain optimum spacing and radiation phasing.

Title: Improvements relating to electric current transformer arrangements

Abstract: 641,370. Transformers. KING, A. J., MAGUIRE, C. R., DODDS, J. M., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 1, 1947, Nos. 31729 and 32876. [Classes 35 and 38 (ii)] Apparatus for deriving a current at voltage which is representative of th( current flowing in a higl voltage line comprises two devices, one for changing alternating current into mechanical vibrations, the other for changing mechani cal vibrations into alter nating current, the two devices being joined by insulating means capable of transmitting vibrations be tween the devices and o: withstanding the line volt age. Nominal insulation between the line 7 and the secondary winding of the current transformer 8 is permitted by the provision of devices 1, 2 which each comprise a coil 4 wound on a cylindrical former 5 and suspended in the field of a permanent magnet 6. Application of alternating current to the coil 4 of the device 1 causes it to vibrate axially and the vibrations are transmitted to the device 2 by an insulating tube 3, which is made long enough to insulate the device 2 from the line voltage, so that the coil 4 of the device 2 generates a voltage or current which, when applied to the primary of a transformer 9, enables a current or voltage to be obtained from the secondary which is representative of the line current. The former 5 may be made of metal to provide damping, or mechanical damping may be provided, to avoid transient effects. In further embodiments the devices are arranged to have torsional vibrations and may comprise a wound armature moving in a permanent magnet field or a permanent magnet armature moving in a wound field system. If desired the output voltage of the device 2 may be differentiated in known fashion so as to be more nearly representative of the line current, also the phase angle between the output voltage and applied current may be reduced by suitable arrangements. In some applications of the invention the insulating tube 3 may be made of resistive material and used as the series resistor for a voltmeter or wattmeter.
