Title: Improvements in or relating to liquid level sensitive apparatus
IPC: G01F23/26
Filed: 1948-02-24
Abstract: 674,034. Liquid level measurement; capacitance and inductance measurement; electric condensers. WHEELCO INSTRUMENTS CO. Feb. 24, 1948 [May 3, 1939], No. 5451/48. Class 37. Fig. 1 shows apparatus sensitive to the level 4 of liquid in a container 2, which is connected to a non-metallic gauge tube 6 carrying a pair of separate vertical conductors 7, 8 forming the plates of a condenser, of which the tube and the liquid therein form the dielectric. This condenser tunes the grids inductance 12 of a thermionic oscillator 18, whose anode current is fed through a relay 24 whose moving contact 35 controls the direction of rotation of a reversible split-field motor 30 through an anti-hunting device in which rotary cam 32 closes contacts 34, 38a in the motor circuit at timed intervals and introduces a lag between relay closure and motor operation. The motor drives the shaft of a variable condenser 25 tuning the anode inductance of the oscillator, and also drives a liquid level indicator pointer 26a moving over a dial 26. A level recorder may also be driven by the motor. When the liquid is at a predetermined normal level, the plate circuit is tuned slightly off-resonance with the grid circuit and the constants are such that the anode current holds relay contact 35 neutral between contacts 36 and 37. A change in liquid level alters the grid tuning capacity so as to decrease or increase the difference in tuning between grid and anode circuits, and thus decreasing or increasing the relay current. to close either contacts 35, 37 or 36, 37 depending on the sense of the change, so that the motor retunes the anode circuit with the grid circuit thus restoring the relay contact 35 to neutral; and rotates pointer 26 to indicate the new liquid level. Inductance instead of capacity may be varied by the liquid level, Fig. 2 (not shown). The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 674,113 which is referred to. This subject-matter does not appear in the Specification as accepted.

Abstract: 117,825. Cruz, J. L. V. da. April 23, 1917. Non-contact-making relays; variable-resistance transmitters. - Apparatus for detecting and measuring weak magnetic forces, especially from distant sources, is applicable for use in detecting submarines, exploding mines and directing torpedoes, and comprises a suspended or pivoted magnetic system acting upon microphones or special contact resistances. The magnetic system may be a single magnet or an astatic system, a coil or an electromagnet, and may be mounted in gimbals or supported by a float. In the arrangement shown in Fig. 1, a system comsisting of a long magnet A and a pair of shorter magnets B is pivoted at E and is rendered astatic by the influence of bars C and F of soft iron; the system is held between a pair of microphones M, and is controlled by a pair of adjustable magnets or coils D. The magnetic system may be replaced by reducing the parts to one side of the pivot by a counterweight. In the modification shown in Fig. 3, two magnets A<1>, A<2> are mounted coaxially on a non- magnetic bar B' pivoted at E, with two similar sets of soft-iron bars C, F, magnets D and microphones M arranged in perpendicular planes, horizontal and vertical for instance, to indicate separately the corresponding components of the magnetic force.

Title: Improvements in spray damping machines for textile fabrics
Inventor: JOHNSON JACK
IPC: D06B1/00
Filed: 1959-02-19
Abstract: <PICT:0870404/IV(c)/1> In a spraying apparatus for textile fabrics in continuous length in which spray is applied to both faces of the fabric whilst the latter is travelling in a vertical direction between spraying devices mounted in a container, a set of nozzles is directed to eject liquid vertically downwards on to a pair of pivoted perforated sprayboards by which the spray is converted into a mist directed towards the fabric, the inclination of the sprayboards being varied by an electric motor or other means to control the volume of mist impinging on the fabric.  As shown in Fig. 1 fabric 1 may be fed through inlet slot a between adjustable plates a1 so as to travel vertically upwards through container A leaving through slot a3. Spray nozzles B direct liquid on to sprayboards C the surfaces of which may be covered with wire gauze.  Sprayboards C may be pivoted at C such that their inclination may be varied.

Title: Hydraulic pressure-proportioning valves for motor vehicle braking systems
IPC: B60T8/26
Filed: 1965-02-11
Abstract: 1,040,524. Fluid pressure brakes; valves. GENERAL MOTORS CORPORATION. Feb. 11, 1965 [Feb. 27, 1964], No. 5940/65. Headings F2F and F2V. An hydraulic pressure reducing valve particularly suitable for reducing the pressure of hydraulic fluid to the rear brakes of motor vehicles comprises a body 32 within which a valve element 42 having an extension 44 is urged towards an open position by a spring 54 and towards a closed position by hydraulic pressure acting on the area of the extension 44. In operation, at low pressure the valve is open and fluid supplied through a pipe 24 passes between a valve seat 52 and an O ring 50 to an outlet pipe 28. As the pressure increases the valve element is moved to the right against the force exerted by the spring 54 by fluid pressure acting on the area of the extension 44 until the O ring 50 seats against the valve seat 52 closing the valve. When a further increase in inlet pressure occurs an unbalanced force due to hydraulic pressure on the area within the O ring tends to re-open the valve allowing a small quantity of fluid to pass an elastomeric O ring seal 50 causing the outlet pressure to rise at a rate less than but dependent upon the inlet pressure. A one-way valve 62 allows fluid to return from the pipe 28 to the pipe 24 when the inlet pressure is removed. In another embodiment, Fig. 4 (not shown), an inertia mass 78 holds the one-way valve in an open position, rendering the pressure reducing valve inoperative, until a predetermined deceleration is attained when the oneway valve closes and the pressure reducing valve operates as previously described. In another embodiment, Fig. 5 (not shown), an inertia mass 120 is attached to the valve element by a link 128 and holds the valve in open position until a predetermined deceleration is attained.

Title: Improvements in or relating to electrical counting devices
Inventor: LONG ARTHUR
IPC: H03K29/00
Filed: 1958-02-26
Abstract: 859,922. Electronic counting-apparatus. HILGER & WATTS Ltd. Feb. 24, 1959 [Feb. 26, 1958], No. 6170/58. Class 106 (1). An arrangement for indicating the state of a cold-cathode glow-transfer counting tube comprises trigger tubes connected one with each counting tube cathode, the arrangement being such that the trigger tubes are normally cut off but are pruned when an indication of the count is desired. Positive pulses 5 to be counted operate a single shot multivibrator 1 whose output is passed via a cathode follower 2 to step on the discharge in a multicathode counting tube 32. The cathode receiving the discharge applies a positive potential to an associated trigger tube 61- 70 which does not fire if the switch S1 is closed due to the bias applied to a line 39. When the switch S1 is opened (as shown) the potential of the line 39 drops and the primed tube 61-70 fires, the energy required being provided by the discharge of a capacitor 112. The tube, therefore, remains fired even if the discharge in the counting tube 32 steps on. The operating potentials required are derived from a transformer 113. Outputs 101-110 may be connected to a mechanical printer which records a digit corresponding to the fired tube. A plurality of counting stages may be provided. The tube 32 may be a binary instead of a decimal counter.
