Title: Improvements in or relating to mechanism for feeding molten glass
IPC: C03B5/18
Filed: 1929-04-27
Abstract: 330,366. Jackson, L. Mellersh-, (Hartford-Empire Co.). April 27, 1929. Gathering.-Relates to apparatus for circulating molten glass in a gathering-pool or forehearth, particularly for use in connection with suctiongathering machines. According to the invention, the glass is moved by an impeller which has an alternating motion and co-operates with one or more stationary baffles aranged in the forehearth to cause the glass to circulate in a definite path. The apparatus may comprise a forehearth 16, Fig. 9, having at its front end an opening through which a suction head 122 is inserted periodically to gather charges of glass at the point 26. An impeller or paddle 24 dips into the glass and is arranged to oscillate about a pivot 55 with a rapid forward stroke and a slower rearward stroke. The paddle co-operates with a baffle which may be in the form of an island 50, Fig. 1, built up from the floor of the forehearth and situated behind the gathering point 26. The baffle may have an extension 51 which does not reach the surface, so that the glass is shallower at the gathering point 26 and a flow of greater velocity past this point will be produced by the stroke of the paddle. In a modified construction, the baffle is placed in front of the paddle and the glass is forced over it by the forward movement of the paddle. In another construction, shown in Fig. 5, the paddle moves between two baffles 61, 62 which confine the glass and prevent it from flowing sideways The floor 63 between the baffles may be raised to reduce the depth of glass below the paddle. In a further construction, shown in Fig. 7, baffles 64, 65 are arranged to direct the flow of glass to one side of the forehearth, and a submerged dam 66 is provided to prevent the glass from flowing back when the paddle is retracted. The paddle may be so operated that its rearward stroke is quicker than the forward stroke, and the glass is then drawn away from the gathering-point instead of being urged towards it.

Title: Improvements in and relating to pulse generators
Inventor: ENGLAND THOMAS SIDNEY
IPC: H03K3/55
Filed: 1947-05-16
Abstract: 637,813. Pulse generating circuits. MINISTER OF SUPPLY. May. 16, 1947, No. 13236. [Class 40 (vi)] In a pulse generator in which high power pulses are produced by applying a low-voltage D.C. input to the primary winding of a step-up transformer via a switch, the secondary of the transformer feeding a pulse-forming network and a load, means are provided to ensure that at the instant at which the primary switch is to be opened the voltage across it is substantially less than that of the D.C. input. Fig. 5 shows a generator in which the primary and secondary switches comprise grid-controlled mercury valves of the type described in Specification 635,147. Both valves are normally non- conductive and capacitor C1 charges via inductor L1 at a substantially constant rate from the D.C. supply D, a positive pulse of short duration applied to grid W1 renders the left-hand section of the valve conductive to charge the pulse forming network N from capacitor C1 via the step-up transformer T. When the current in the primary winding of the transformer has fallen substantially to zero, the primary switching valve begins to de-ionize and eventually becomes an open-circuit. A positive pulse of short duration is then applied to the grid W2 of the secondary switching valve and the pulseforming network N discharges through the transformer Q to produce a pulsating current through the load R1, the secondary switch then de-ionizes and the cycle is repeated. The value of capacitor C1 is made less than the effective capacity of network N referred to the primary circuit so that on discharge the voltage across capacitor C1 reverses in sign. The values of inductor L1 and capacitor C1 are chosen with respect to the pulse recurrence frequency so that C1 charges in a substantially resonant manner. In a modification, Fig. 6 (not shown), the values of the input inductor and capacitor are chosen so that the capacitor charges in a shorter time than the interval between the output pulses and a rectifier connected between the inductor and capacitor ensures that the capacitor remains charged to the peak voltage and the amplitude of the output pulses is maintained constant even if the intervals between successive operations of the switches &c. varies within wide limits. The pulses required for the operation of the primary and secondary switches may conveniently be derived from the leading and trailing edge of a square wave of predetermined width.
