Abstract: 1,155,588. Measuring fluid-flow rate electrically. P.J.F. CALVET. June 28, 1966 [June 28, 1965; Feb. 17, 1966; June 22, 1966], No.29032/66. Heading G1N. In apparatus for measuring the rate of flow of a fluid by its coating effect on a heated resistor, the resistor is fed with a pulsed current and the rate of change in temperature of the resistor after each pulse is measured to determine the fluid-flow rate. As shown Fig. 1, a timer B causes an EMF source E, e. g. an oscillator to feed power to a resistance transducer or thermocouple CA until its temperature reaches a first predetermined value, when a first trigger circuit B1 is operated and oscillator E is disconnected from the transducer CA. When the falling temperature reaches a second predetermined value a second trigger circuit B2 operates and the time interval between the operation of B1 and B2 is measured at IM and is indicative of the rate of fluid-flow. The switch S may constitute a vibrating relay which connects transducer CA alternately to the EMF source E and a measuring amplifier Ap Figs. 3, 5 (not shown). In further embodiments the rate of change of temperature of the transducer is sensed by measuring the temperature difference over a fixed time interval in the heating cycle Fig. 7 (not shown), or by continuously differentiating an electrical signal representing its temperature Fig. 9 (not shown). The principle of the invention may be used to measure other parameters, e.g. the viscosity of a fluid, by applying pulses of momentum to a paddle and measuring the rate of charge of its displacement.

Abstract: 1,136,839. Capacitors. ILLINOIS TOOL WORKS Inc. 23 June, 1967 [27 June, 1966], No. 29200/67. Heading H1M. In a method of making a capacitor, a strip of dielectric material is wound into a roll, and during the winding, strips 14, 16 of conducting electrode material are brought into contact with the dielectric strip at locations so spaced apart that at the end of the winding the strips are separated by a predetermined thickness of dielectric, leads 18, 20 being brought into electrical contact with the respective electrodes in positions such that in the finished capacitor they are out of the electric field existing between the electrodes. The length of each electrode strip is substantially the same as the circumference of the roll when it is fed. The electrode strips may be attached to opposite sides of the dielectric strip, and the leads bonded to opposite sides of a second outer dielectric strip so that they contact the electrodes on winding (best seen in Figs. 4 to 7, not shown). Alternatively, two dielectric strips may be employed, each lead being bonded to the strip which is not the one to which its associated electrode is held. In the winding apparatus shown in Fig. 11, the electrode strips are fed from supply reels and held on vacuum drums 36, 38, cut by blades mounted on cutter drums which co-operate with slots in the vacuum drums, and controllably released therefrom on to opposite sides of the dielectric strip, being held by electrostatic attraction due to circuit 58 or, alternatively, by adhesive. At the same time leads 32a, 34a are bonded to dielectric strip 21 by electric heating or by preheating them. When winding is finished, the last turns of dielectric are heatsealed. The dielectric may then be heatshrunk.

Title: Improvements in and relating to washing machines
IPC: D06F13/00
Filed: 1939-11-03
Abstract: 535,318. Washing and drying machines. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 3, 1939, No. 29319. Convention date, Nov. 3, 1938. [Class 138 (ii)] Relates to a washing-machine of the kind in which clothes are washed and centrifugally dried in a single receptacle as described in Specification 452,402. According to the invention, a filter is supported on the receptacle, and means are provided for circulating the washing-liquid from the receptacle on to the filter during washing, and for admitting rinsing-liquid directly to the receptacle while the receptacle is rotating at high speed. The device comprises an outer casing or tub 1 provided with an open top closed by a cover 4. A washing compartment or receptacle 6 is supported above the bottom 5 of the casing, the space between the receptacle and the bottom being sufficient to store the liquid contents of the receptacle. The receptacle is supported by a tubular post 8 through which extends the shaft 8a that oscillates the agitator 7 and rotates the receptacle for centrifugal drying. In the bottom 5 is an outlet 9 connected to the inlet of a pump 12 through a valve 13. During washing the liquid continuously flows out to the casings through holes 22 in the upper edge of the receptacle, and is withdrawn from the bottom of the casing by the pump 12 and discharged through a conduit 14 and a gooseneck 15 on to a filter 16 carried by a ring 17 supported by a cover 4. The liquid is thus filtered continuously during washing, and suspended particles are removed. The gooseneck 15 may be turned to discharge the liquid into a drain. At the conclusion of the washing-operation, the receptacle is rotated rapidly to dry the clothes, and during this operation, the pump 12 is inactive but the valve 13 is opened so that liquid thrown outwards through the holes 22 collects in a trough 24 and runs through a conduit 25 into the casing. After the washing- liquid has been partly removed from the clothes. rinsing-liquid may be introduced into the receptacle through a conduit 26, and the liquid flows through the clothes and escapes through the holes 22. During rinsing, the valve 13 is closed and the pump operated, the gooseneck 15 being turned to discharge the liquid into a drain so that it does not dilute the washing- liquid. The rinsing liquid may also be introduced through a conduit 27 which discharges into an annular trough 28 formed by a wall 29 fixed to the bottom of the receptacle. The liquid enters the receptacle through openings 30 which are small enough to prevent lowering of the liquid level in the receptacle during washing. In modified constructions, the filter is of annular shape and is mounted on the upper edge of the receptacle, the opening in the filter being large enough in some cases to permit insertion of the clothes into, and removal from, the receptacle. During drying, and before the rinsing-liquid is introduced, solid particles may be flushed from the filter by discharging liquid on to the filter.
