The flux serves to prevent oxidation, to insulate, to lubricate and to remove alumina. The wollastonite may be pure synthetic or natural CaO.SiO 2  or CaO.SiO 2  in solid solution with at least one of SiO 2 , CaO and Al 2 O 3 , e.g. pseudo wollastonite or rankmite. The low melting flux constituent with a melting point of 700-1300‹ C. may be Na 2 CO 3 , K 2 CO 3 , NaF, KF, LiF, AlF 3 , Na 3 AlF s , CaF 2 , boric acid or a borate and comprises up to 45% wt. of the flux. The flux may also contain millscale up to 15% wt. of expanded vermiculite, perlite or pumice and up to 20% wt. of carbonaceous powder. A preferred flux contains 50-75% wollastonite, 4-20% perlite and 1-12% Na 2 CO 3 . 0À5-1À5 kg. of flux is added per 1000 kg. of cast steel.

Abstract: 317,820. Compagnies Reunies des Glaces et Verres Speciaux du Nord de la France. Aug. 23, 1928, [Convention date]. Rolling.-A method of producing plate glass in a continuous strip consists in making the glass in a pot furnace, pouring the contents of each pot successively into a heated container which maintains the glass therein at the proper temperature for rolling, and in flowing the glass continuously from the container into a rolling machine, each pot being poured into the' container before the whole contents of the preceding pot has flowed into the rolling machine. The apparatus comprises a pot furnace 1 of known type, a container 2, a rolling apparatus 3, and a leer 4 of the roller-conveyer type. The container 2 consists of a small tank furnace heated by burners 8 and provided in one wall with a horizontal slot 7 through which the glass flows into the pass between the rollers 3. The floor 5 of the furnace is inclined towards the slot 7 and is extended outside the furnace to form a pouring or receiving table 6. The floor may also be wormed with a recess 9. In a modification, a part of the floor near the outlet slot may be horizontal. The dimensions of the container are such that it will hold more than the contents of one pot but less than the contents of two.

In apparatus for recording maximum and/or minimum values of a variable measured electrically by a null method, the unbalance signal from a bridge circuit is fed through a chopper amplifier 3 to winding 4 of rebalancing motor 1, and to a phase-sensitive rectifier 5 feeding the electronic equivalent of a polarized relay 6, controlling a dot-printer. A phase change in the unbalance signal, representing a maximum or minimum value of the measured variable, produces a change in direction of the motor 1 and a change in polarity at the output of the relay equivalent 6, which initiates a printing operation, and stops the motor.

Title: Improvements in or relating to burner control apparatus
IPC: F23N5/20
Filed: 1970-04-28
Abstract: 1299758 Ignition and control system for burners HONEYWELL Inc 28 April 1970. [11 July 1969] 20433/70 Headings F4F and F4T An ignition and control apparatus for a burner 54 having a fuel valve 53, comprises a spark igniter 55, an electromagnetic radiation sensor, preferably u.v. sensor 63, to sense ignition sparks and, after valve 53 has been opened as a result, ignited fuel, a flame rectification sensor 59 to sense burner flame establishment, means, including timer capacitor C 3 , for establishing a trial for ignition period, lockout means for closing the valve 53 if ignition is not established before the end of the period, and means to prevent lockout and to turn off the igniter if the sensor 59 senses the pressure of a flame.  A.C. power is supplied to the apparatus through terminals 30, 31 and step-up transformer 33. On a first positive half-cycle (when conductor 35 is positive with respect to conductor 34) timing capacitor C 3  charges and the gate voltage of transistor Q 1  drops and allows the transistor to charge capacitor C 5 . When the charge on capacitor C 3  decays through resistor R 4 , e.g. after about 10 sec., the apparatus will lockout unless sensor 59 has sensed a burner flame. On the next-half cycle, a negative one (when conductor 35 is negative with respect to conductor 34) fluid effect transistor Q 1  blocks capacitor C 3  from discharging and capacitor C 5  turns on thyristor Q 2  to put conductor 43 at a negative potential and to turn on field effect transistor Q 3 , which thereby triggers thyristor Q 4 . Capacitor C 6  now charges as Q 5  cannot conduct in the absence of a gate pulse, and capacitor C 10  is charged via thyristor Q 2 . On the next positive half-cycle. currents set up in the resisters R 19 , R 18 , R 16  trigger thyristor Q 5  and capacitor C 6  is discharged causing a spark at spark plug 55. On sensing the spark, ultra-violet sensor 63 becomes conducting and current, bolstered by the charge on capacitor C 10 , passes through diode CR 8 , resistor R 25  and ultra-violet sensor 63, to store energy in inductor L 1 . On the next negative half-cycle the energy in conductor L 1  produces a current in diodes CR 10 , CR 11  to charge capacitor C 9  and bias field effect transistor Q 7  on, and thereby charge capacitor C 8 . On the next positive half-cycle the charge on capacitor C 8  produces a current to trigger thyristor Q 6  and energize solenoid 64 to turn on fuel valve 53. On ignition of the burner, flame rectification sensor 59 senses the flame and produces a current in conductor 47 to maintain a charge on capacitor C 3  and prevent lockout and to cut off transistor Q 3  and hence thyristor Q 4  and capacitor C 6  cease to operate but transistor Q 1  and thyristor Q 2  remain conducting. In the event of lockout occuring the system may be reset by switching off the power supply momentarily.

Abstract: 797,202. Dielectric heating. RADO, L. July 5, 1954 [July 23, 1953], No. 20486/53. Class 39(3) In welding thermoplastic material by dielectric heating between opposed non- rotatable H.F. electrodes, at least one electrode 1, 3 presents a welding surface of semi-circular or quarter-circular cross-section of a radius greater than the thickness of the material to be welded, so that the electrodes on meeting touch each other only on a line. Both electrodes may be semi-circular or one electrode may be flat. The thermoplastic is thus sealed along a line 6 and is either cut along the line or is thinned to be easily tearable.

Abstract: 148,806. Leipziger Schnellpressenfabrik Akt.-Ges. vorm. Schmiers, Werner, & Stein. March 2, 1918, [Convention date]. Sheet carriers and registering devices; grippers. - A laying-on device for feeding sheets to a rotary printing-machine of the kind in which an oscillating arm carrying grippers takes the sheet from a feed table and feeds it to the grippers of the impression cylinder, is so constructed that the grippers are carried in spring-pressed bearings which can yield in a radial direction on the arm which carries them. As shown, the sheets are fed over a table a to registering devices m on bearings h in which the shaft g of the feeding-grippers h is mounted. The bearings h are carried by arms c on which they can slide against the action of springs l which normally press the grippers in an outward direction to an extent controlled by adjustable stops k. In the event of a double feed or other disturbance, the grippers g can yield without liability of being broken, and mechanism is provided for automatically withdrawing the grippers g away from the impression cylinder on the return of the arm c to the feed-table a. This mechanism takes the form of a cam which is oscillated in a lateral direction and moves the grippers away from the impression cylinder on the return motion of the arms c.
