Patent GB-1052430-A (GB)
IPC: G01F15/08
Abstract: 1,052,430. Liquid dispensing apparatus. MOLKEREIMASCHINEN G.m.b.H. & CO. Jan. 14, 1964, No. 1582/64. Heading A4T. [Also in Divisions B1 and B8] Liquid, e.g. milk, is metered in flowing from one receptacle 1 to another higher receptacle 13, the liquid being degassed in flowing through an intermediate tank 4. Initially valve 11 is closed and vent 7 is open with float 5 lying on the tank bottom. As pump 1 starts to pump milk from tank 1 into the intermediate tank, float 5 rises and forces air out until liquid rises to a level where the float closes the vent. Pressure in the tank then increases and is sufficient to open valve 11 to permit discharge to tank 13, the milk being metered by device 9 as it flows through line 10. Any air entrained in the milk separates out in tank 4. When storage receptacle 1 is empty and air is pumped into tank 4 the float will drop and vent 7 will open. The resulting drop in pressure causes valve 11 to close, and discharge to tank 13 ceases.

Abstract: 1,225,665. Pulse modulation systems; demodulators. QUINDAR ELECTRONICS Inc. 18 April, 1968, No. 18490/68. Headings H3A and H4L. In a telemetering system in which a pulse repetition frequency is modulated in accordance with the amplitude of an input signal, the transmitter is provided with a negative feedback circuit including a frequency-to-voltage converter using a saturable transformer with a square hysterisis loop and errors in the received signal are minimized by arranging that the receiver comprises a similar frequency-tovoltage converter. Transmitter, Fig. 1.-The output of a transducer 20 is chopped by a field effect transistor 28 under the control of an oscillator 30, amplified at 34 and reconverted to a direct current by a synchronous demodulator 36 also controlled by the oscillator 30. The output of the demodulator 36 is supplied to the common base circuit of a pair of transistors (136, 138), Fig. 3 (not shown), respectively controlling the discharge of timing capacitors in a conventional multivibrator circuit 38 to convert the input voltage to a corresponding pulse repetition frequency which modulates a carrier at 40 for transmission. The output of the voltage-tofrequency converter 38 also is amplified at 42 and re-converted to a voltage at 44 the converter 44 including a saturable transformer having a square hysterisis loop producing in its secondary winding for each transition in saturation, pulses in which the voltage-time integral is independent of the input voltage, temperature &c. These pulses are rectified, smoothed at 45 and the difference between the resulting voltage and a reference voltage from 48 is applied as negative feedback to the input of F.E.T. 28, the gain of amplifier 34 and converter 38 being sufficiently high for the system to be controlled by the characteristics of the feedback path. Receiver, Fig. 2.-The received carrier is demodulated at 49 and supplied to a pulse demodulating circuit comprising amplifier 50, frequency-to-voltage converter 52, filter 53 and reference comparator 54 which are identical to components 42, 44, 45 and 48 of the transmitter.

A body of yarn e.g. a complete yarn package rendered waste by damage or unsatisfactory spinning, is stripped from a core on which it is wound by cutting a longitudinal notch in the body, using a rotary cutter and to a depth just, say one-sixteenth of an inch, short of the core surface, and then severing the remanent uncut turns of yarn along the apex of the notch e.g. in the case of thermoplastic yarn, by a directed jet of hot fluid such as air. In the device shown, a bobbin 1 of yarn 2 is automatically positioned on a table 3 located by a spigot 4 engaging the tube 5, and secured by pressure of a head 6 of a hydraulic ram on one end 7. An annular (or partially annular) blade 10 carried on an inverted dished support 8 is rotated and moved (in a cutting and a return stroke) relatively to and axially and (if necessitated by the contour of the bobbin) laterally of the bobbin by a pneumatic (or hydraulic) piston and cylinder mechanism (not shown) so that it cuts a notch 12. Provision is made for the change in direction of the surface of the bobbin e.g. from the frusto-conical portion 1a to the cylindrical portion 1b, by altering the alignment of the piston and cylinder by means of a cam in response to a limit switch (not shown) actuated when the blade-support reaches an appropriate position relative to the changing bobbin surface.

[Also in Division H2] In electrical resistance welding an alternating current is supplied to the electrodes in contact with the work, of such a frequency that the reactance of the welding current circuit including the electrodes and the work is higher than the resistance of the circuit. An apparatus for making metal blanks 11 into tubular cam bodies comprises a horn 12 and advance means 13 for moving the blanks 11 along the horn and an apparatus 14 for forming the blanks into tubular shape encircling the horn with overlapping edges. Roller electrodes 18, 24 are provided to contact between them the edges to be welded, although sliding or shoe electrodes may be used. The roller is mounted on a fluid piston/cylinder device 30, 31 so that the roller 24 is pressed tightly to sandwich the edges to be welded. Alternating current is supplied from a generator 35 including a step down transformer to the electrodes 18, 24 and a tack welder including electrodes 37, 38 may be provided to tack weld the overlapping edges prior to insertion between the electrodes 18, 24.

Abstract: 1,266,406. Magnetic storage apparatus. COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE. 25 March, 1969 [28 March, 1968; 7 March, 1969], No. 15632/69. Heading H3B. An anisotropic thin film memory is provided with a magnetic shield of isotropic or anisotropic magnetic material to control the apparent coercive field of the memory elements. Thin magnetic film storage elements 2 in the form of discrete areas, strips or continuous film are deposited on a glass or ceramic substrate 1 backed by ground plane 9 with their easy axis A in the direction shown. Word drive conductors 5 and bit conductors 3 on insulating sheets 6, 4 are superimposed on the film elements. In accordance with the invention shields 7 of soft isotropic magnetic material having a very low coercive field or anisotropic material having its easy axis perpendicular to that of the storage elements 2 is coated on the bit conductors 3. The relative positions of the films 2 and 7 may be reversed, Fig. 3 (not shown), and a further set of conductors parallel to the bit conductors may be included below or between the storage elements 2 and shields 7, Figs. 4, 5 (not shown). In another arrangement the conductors 5 may be positioned below the storage elements. The conductors may be in the form of wires and/or strips with the wires within a groove or deposited on a soft magnetic plate for forming a closed flux path, Figs. 6 to 9 (not shown). The effect of the shields 7 when no currents are applied to the word and bit conductors is to increase the apparent coercivity field of the storage elements without any increase of their anisotropic dispersion so that creep and disturbances from spurious magnetic fields during read/write operations are prevented. During read/write operations when currents are applied to the conductors the shield saturates and becomes inoperative at those elements which have been selected enabling the read/write operations to be carried out. The reduction in creep enables the thickness of the storage elements to be increased. To further improve the protection against interfering magnetic fields the word conductor may be divided into parts 5<SP>1</SP>, 5<SP>2</SP> arranged respectively on opposite sides of the shield 17, Fig. 12 (not shown). This arrangement ensures that the shielding effect is maintained provided that both word and bit conductors are not simultaneously energized which results in the shield being saturated. As shown in Fig. 13 an additional shield layer 107 and a further two layer system of conductors 1051, 105<SP>2</SP> may be provided. The shielding 107 does not disappear until both conductors 105 and 3 are energized. Thus in order for the shielding effect to be cancelled at a point currents I 1 , I 2 , I 3  must all be present.
