Title: Device for measuring and/or monitoring the flow velocity of a flowing fluid
IPC: G01P5/10
Filed: 1974-12-02
Abstract: 1494636 Measuring fluid-flow rate electrically ELEKTRONIK-KONSTRUKTIONER AB 2 Dec 1974 [3 Dec 1973] 52105/74 Heading G1N A flow measuring or monitoring device comprises a pair of similar temperature sensors, each comprising a monolithic semi-conductor crystal, one of which is associated with a heater arranged to heat it by a constant amount and means for comparing the outputs of the sensors to obtain flow velocity. The device may be used to operate an alarm when flow velocity deviates from a desired value.  The sensors 8, 10 may be arranged on a sheet 6 projecting into the fluid stream with its plane parallel to the direction of flow. A radiation shield 12 is sited between them and circuitry and an alarm may be contained in a unit 4 on the exterior of the conduit wall 2. Each sensor 8, 10 may comprise an identical array of four bi-polar transistors T3, T4 Fig.3, integrated on the same silicon wafer, three being connected, as shown, and one 18 being used as a heater in the sensor 10. The corresponding one in the sensor 8 is not utilized. Heater current is supplied to drive the transistor 18 in the reverse direction, by a conventional stabilized voltage assembly I with potentiometer R6 providing for voltage adjustment. Capacitor C2 is a noise filter. The sensor circuit includes a potentiometer R13  for the sensor 8 for voltage adjustment and potentiometers R10, R14, the former for fine adjustment in temperature compensation for the sensor 10 and to account for manufacturing tolerances between the sensors and the latter to adjust the point at which an alarm indicates that flow has deviated from the desired flow valve. Capacitor C3 is a noise suppressor and also forms the shield 12. The two diode paths are connected to a level discriminator IC2 and to a relay Rel which energizes the alarm. The sheet 6 carries some of the circuitry in printed form. The device may be used to regulate flow rather than operate an alarm. Uses described relate to air-flow control.

Filed: 1973-11-12
Abstract: 1443758 Resistance elements for potentiometers TRW Inc 12 Nov 1973 [4 Dec 1972] 52475/73 Heading HIS A resistance element 10 comprises a wire core 12, e.g. of copper, an insulating layer 14 which extends beyond the core ends, a helical winding of resistance wire 16 about the layer 14 including the latter's extending ends, and an outer protective layer 18. As shown a strip of the layer 18 is out away by buffing or an abrasive blast to form a track 20 so that the element may be used in a variable resistor. A batch of elements is made by coating a number of elongated wire cores (Figs. 2, 3, not shown) with polyimide resin, winding each with a resistance wire, and applying a protective coating of polyimide or epoxy resin which is cut away to form the tracks 20. The cores are placed in spaced, parallel relation and encased in a plastics block (26) which is then cut transversely into a number of wafers (28, Figs. 4, 5, not shown). The exposed ends of cores 12 are etched away so that the ends of layers 14 project and an outer portion of the plastics block is removed by solvent to expose the ends of protective layers 18. The exposed ends of the cores and of the layers 18 are then coated with an insulating film 22 and the rest of the plastics block is dissolved to leave the finished elements. Helical resistance elements may be made by forming the wound, elongated cores into helices and processing in a block as before.

Abstract: 1,092,520. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. Dec. 31, 1964 [Dec. 31, 1963], No. 52961/64. Heading H4K. [Also in Division G4] The call store, for the No. 1 ESS, comprises a plurality of blocks of memory (ferrite sheet stores 0 to 4, Fig. 20) each of which consists of independent left- and right-hand halves. The data in the left-hand half of each block is duplicated in the right-hand half of an adjacent block and either data may be addressed by central control over either of duplicate address bases 6401 and 6402. With an odd number of blocks, the standby central control can not normally address all the data; viz that shown as E is only addressible over the " 0 " bus which is usually used by the active central control. However all the data can be read out to either central control over the response bus system. In the event of a faulty store, higher priority data therefrom is written into another store in place of lower priority data contained in the other store. Thus in the lower part of Fig. 20, store 2 is faulty and the A data has been written in to store 2 in place of the original C data whereby A data is still duplicated (stores 0 and 2) but the B and C data now only occurs once. The necessary logic for addressing the store under normal and maintenance conditions is as described in Specification 1,081,811- Specification 1,081,817 inclusive.
