Abstract: 1,228,335. Gas igniter system; burner control system. FENWAL Inc. 15 Jan., 1970 [24 Jan., 1969; 31 Dec., 1969], No. 1963/70. Headings F4F and F4T. [Also in Division H3] In an alternating current . powered transformerless gas igniter system, gas is provided to an electrically earthed burner 11 from a supply main 13 through a valve 15 which is mechanically coupled to and controls a switch SW1, which is closed when the valve 15 is opened, allowing rectified current to flow through a diode D1 and resistors R1 and R2 to charge a timing capacitor C4 to a voltage which causes a neon lamp N1 connected between the timing capacitor C4 and the gate of a silicon controlled rectifier Q1 to conduct so triggering the SCR Q1 allowing an energy storage capacitor C3, which is charged by current flowing through the diode D1 and the resistor R1, to discharge through a circuit including the SCR Q1 and the primary winding W1 of a spark coil 23, as a result of which a current is induced in the secondary winding W2 of the spark coil 23 and causes a spark between an electrode 21 and the burner 11, both of which are connected in circuit with the secondary winding W2, so igniting the gas at the burner 11. A large isolating resistance R6 is connected between the side of capacitor C4 which is not earthed and the side of the secondary winding W2 of the spark coil 23 opposite to the electrode 21, in order to substantially isolate the burner 11 from the power supply, so reducing the risk of electric shock. A capacitor C2 is connected between the burner 11 and the secondary winding W2 to act as a discriminator allowing igniting pulses to pass while presenting an open circuit to the D.C. charging current flowing to the timing capacitor C4. The gate of the SCR Q1 is connected to the neon lamp N1 via a resistor R4 and to the power supply lead L2 via a resistor R5. The charging of the capacitors C3 and C4 and the firing of SCR Q1 will repeat periodically as long as the spark gap has a high impedance; but when the gas has ignited at the burner 11, the impedance will be low enough to shunt the capacitor C4 and prevent its being charged to the voltage necessary to fire the neon lamp N1. In another embodiment (Fig. 2, not shown) adapted for use with A.C. voltages which are of opposite polarity with respect to the ground, an intermediate voltage substantially equal to ground potential is provided by means of a pair of dropping resistors connected in series across the power supply leads. Alternative embodiments (Figs. 3 and 4, not shown) have the discriminating function of capacitor C2 performed by neon lamp (N2) and a second spark gap respectively.

A universal motor 1 connected to an A.C. supply may have a rectifier 3 switched into its supply circuit by means of which one half wave of the A.C. feed is blocked, the motor torque frequency is halved and consequently the speed of the motor is reduced. The switching is by changeover switch 4 or alternatively by an onoff switch (not shown) for by-passing the rectifier. Rectifier 3 is a diode. The speed is also controlled by variable resistor 2 or by a transformer (not shown). Motor 1 is primarily for use in a domestic sewing machine and the diode 3 and switch 4 may be installed on the motor, in the starter housing or in the lead between the mains and the motor. The arrangement is intended to vary the speed while maintaining the torque peaks the same for maintaining the penetration power of the needle in the sewing machine.

Abstract: 1,257,099. Rotary retorts. COLLEGE RESEARCH CORP. 25 Aug., 1969 [30 Aug., 1968], No. 42314/69. Heading F4B. High and low melting point alloys are separated by passage through an inclined rotary retort 4 which is mounted within a gas fired furnace 20. Scrap 5, charged through inlet 6 is conveyed through the retort by screw flight 9 which is secured to but spaced from the internal wall of the retort. Molten low melting point alloys such as those of zinc or aluminium are discharged through screen 7 into container 10, whilst solid high melting point alloys such as steel or east iron are discharged past hinged cover 12 into container 11. A gas heated radiant burner 24 is located in an extension 21 of the furnace 20, above screen 7 to prevent molten metal solidifying on it. The main heating burners (not shown) fire tangentially on to the cylindrical retort wall. Some combustion gases are drawn through screen 7 to pass in counterflow to the scrap through retort 4 to inlet 6; the remainder pass out through controlled roof vents 26. In a modification (not shown), the scrap may be introduced into the lower end of the retort, the solid high melting point alloys being discharged at the upper end.

Abstract: 1,258,022. Gramophone record. MATTEL Inc. 13 Jan., 1970 [17 Jan., 1969], No. 1556/70. Heading G5R. A gramophone record for use in a gramophone in a toy comprises a first annular area 14 carrying a plurality of recorded sound sequences in respective similar spiral grooves G1-G6 and a second annular area 16 divided into sectors S1-S6 each associated with a sound sequence groove and carrying a series of lead-in grooves for that sound sequence groove. Each sound sequence groove, e.g. G4 has a main lead-in groove 34 in its associated sector S4 and a series of secondary lead in grooves 35, 36, 41-45 connected to the main lead-in groove. Thus the accuracy required for indexing of a record and its playback stylus 30 to reproduce a particular sound sequence is much reduced in that the sequence is selected by placing the stylus anywhere in the associated segment area. In a second arrangement, Fig. 2 (not shown), two adjacent annular areas divided into lead-in groove sectors are provided and a particular sound sequence is obtained by indexing both record and stylus to select the associated sector. In a third arrangement, Fig. 3 (not shown), the annular area divided into sectors is nearer the record centre than the area carrying the sound sequence record grooves and the record rotates in the opposite sense. In a further arrangement, Fig. 4 (not shown), two annular areas divided into sectors are provided, one nearer and the other further from the record centre than the sound sequence record area.

The helium is compressed and cooled to below its inversion temperature in a three-stage compressor 1, cooler 2, heat exchangers 3, 5, 6 and 7 and expansion turbine 4 before division into two flows. One of the flows is throttled in a valve 8, heated by unthrottled helium in heat exchangers 7,6 expanded in a turbine 9 and combined with recirculating helium prior to its entry into the heat exchanger 6. The second flow after expansion in a valve 10 to a pressure above its critical pressure and cooled in heat exchangers 11, 12 flows with throttling but without phase change through the magnet coils 13, 14 with a consequential high mass flow rate and high heat transfer coefficient. Helium leaving the coils in gaseous phase is throttled in valves 15, 16 to a subcritical pressure to form a vapour-liquid mixture. This mixture cools elements 17, 18 associated with the magnet e.g. supporting means, and the majority of liquid helium either flows through a heat exchanger 12 or in a liquid separator 20 before flowing through heat exchangers 11, 7, 6, 5 and 3 to the compressor 1 for recirculation.
